Abstract

A clamp includes two clamping units spaced apart from each other, each of which includes a supporting mount, a tightening block and a tightening bolt. The supporting mount has an inclined guide face which faces an object to be clamped, and two through holes through which two fasteners respectively extend to engage an installation plane. The tightening block has a sliding face abutting against the inclined guide face, and is fastened on the supporting mount by the tightening bolt. A threaded portion of the tightening bolt passes through a passage hole of the tightening block to engage an engagement hole of the supporting mount, so that the tightening block is compelled by the tightening bolt to move along the inclined guide face.

Claims

1. A clamp adapted to clamp an object and to be fastened on an installation plane by at least four fasteners, said clamp comprising:

two clamping units spaced apart from each other, each of said clamping units including

a supporting mount that has at least one inclined guide face which is configured to face the object to be clamped, and that is formed with at least one engagement hole, and at least two through holes through which two of the fasteners respectively extend to engage the installation plane,

a tightening block that has at least one sliding face slidably abutting against said at least one inclined guide face of said supporting mount, and that is formed with at least one passage hole to be aligned with said at least one engagement hole of said supporting mount, and

at least one tightening bolt that has a threaded portion, an maximum diameter of which is smaller than a diameter of said at least one passage hole of said tightening block;

wherein said tightening block is fastened on said supporting mount by said at least one tightening bolt, said threaded portion of which passes through said at least one passage hole of said tightening block to engage said at least one engagement hole of said supporting mount, so that said tightening block is compelled by said at least one tightening bolt to slidably move along said at least one inclined guide face of said supporting mount.

2. The clamp as claimed in claim 1, wherein for each of said clamping units:

said supporting mount further has a bottom face opposite to said at least one inclined guide face and adapted to contact the installation plane;

said at least one inclined guide face is two in number, said inclined guide faces being spaced apart from each other along a longitudinal direction where said supporting mount extends;

said at least one engagement hole is two in number, said engagement holes being spaced apart from each other along the longitudinal direction and extending respectively from said inclined guide faces to said bottom face;

said at least one sliding face is two in number, said sliding faces being spaced apart from each other along a longitudinal direction where said tightening block extends, and respectively corresponding to said two inclined guide faces of said supporting mount;

said tightening block further has two abutment faces respectively opposite to said sliding faces;

said at least one passage hole is two in number, said passage holes being spaced apart from each other along the longitudinal direction where said tightening block extends, and extending from said abutment faces to said sliding faces, respectively; and

said at least one tightening bolt of each of said clamping units is two in number, the threaded portion of each of said tightening bolt passing through a respective one of said passage holes of said tightening block to engage a respective one of said engagement holes of said supporting mount.

3. The clamp as claimed in claim 2, wherein:

each of said tightening bolts further has a head portion that is adjacent to said threaded port ion thereof, and that abuts against a respective one of said abutment faces of said tightening block.

4. The clamp as claimed in claim 3, wherein:

said supporting mount further has a fastening face between said inclined guide faces; and

said at least two through holes are two in number, said through holes being spaced apart from each other along the longitudinal direction where said supporting mount extends, and extending from said fastening face to said bottom face.

5. The clamp as claimed in claim 2, wherein:

said tightening block further has an abutting plane configured to face the object to be clamped;

said supporting mount further has an inward plane configured to face the object to be clamped; and

each of said clamping units further includes an upper shim that is disposed on said abutting plane of said tightening block, and a lower shim that is disposed on said inward plane of said supporting mount.

6. The clamp as claimed in claim 5, wherein:

said tightening block further has an external plane opposite to said abutting plane; and

each of said clamping units further includes a decoration cover, and an adhesive component that is disposed between said decoration cover and said external plane of said tightening block, and that adheres said decoration cover to said external plane, so that said decoration cover covers said tightening block, said supporting mount and said tightening bolts.

7. The clamp as claimed in claim 1, wherein:

said tightening block is fastened on top of said supporting mount, said at least one sliding face is located on a bottom side of said tightening block; and

said at least one inclined guide face is located on a top side of said supporting mount.
