Abstract

An ice shaver structure includes a worm shaft, an ice pressing tray installed at the bottom of the worm shaft for controlling ice block, a thread section formed on the worm shaft and engaged with a worm gear, a resisting mechanism installed on the worm gear and having a stopper fixed to an ice shaver and abutted against an axial surface of the worm gear, and a resilient device abutted against the stopper. The resilient device has a position-adjusting fixing element for determining an elastic force produced by the resilient device after being compressed, and the elastic force is acted on the stopper to push the stopper to press against the worm gear, such that the resilient device becomes a relative fixed end which is difficult to turn, so that the worm shaft can be driven by a motor to produced up-and-down displacements.

Claims

1. An ice shaver structure, comprising a base, a pillar erected from the base, and a machine head disposed at the top of the pillar, and the machine head further comprising:

a driving motor, having a driving gear installed thereon;

a worm shaft, having an ice pressing tray installed at the bottom of the worm shaft for controlling an ice block, and the worm shaft having a driven gear engaged with the driving gear and provided for the driving motor to drive the work shaft to rotate by the driving gear and the driven gear;

the worm shaft having a thread section and a worm gear engaged with the thread section, wherein a shaft rod is installed along the axis of the worm gear, and a resisting mechanism is installed on the shaft rod; and

the resisting mechanism comprises a stopper fixed onto the machine head and abutting against an axial surface of the worm gear, and a resilient device pressing at the stopper and having a position adjustable fixing element installed at an end of the resilient device for determining an elastic force acting on the stopper after the resilient device is compressed, wherein the elastic force is acted onto the stopper to increase the friction between the stopper and the worm gear.

2. The ice shaver structure of claim 1, wherein the stopper has a through hole formed at an end of the stopper and sheathed on the shaft rod of the worm gear, and the other end of the stopper is secured to the machine head;

and the resilient device includes a shaft sleeve and a compression spring, and the shaft sleeve having a shaft hole sheathed on the shaft rod of the worm gear, wherein the shaft rod has a key portion disposed thereon and the shaft hole of the shaft sleeve has a key groove, and the key groove of the shaft sleeve and the key portion of the shaft rod are embedded and linked with each other, and a flange is extended from an end of the shaft sleeve and abutted against the stopper;

the compression spring is sheathed on the shaft sleeve and an end of the compression spring abuts against the flange, and the other end of the compression spring is screwed to an adjusting nut of the shaft rod, and the elastic force produced by compressing the compression spring pushes the flange, so that the shaft sleeve abuts the stopper and transmits the elastic force to the worm gear, and the adjusting nut may be turned to adjust the elastic force of the compression spring;

a shaft sleeve with a shaft hole penetrating through the shaft sleeve is installed along the axis of the driven gear, and the shaft hole has a key groove, and the worm shaft has a key portion protruded from the worm shaft for embedding into the key groove, so that the driven gear and the worm shaft are combined integrally.

3. The ice shaver structure of claim 1, wherein the worm shaft has a junction at the bottom of the worm shaft, and the ice pressing tray has a first side and a second side back to back to each other, and the first side has a shaft base, and the shaft base has an insert hole for receiving the junction and coaxially plugging the junction, and the shaft base has a plurality of pin slots formed along the radial direction of the insert hole, and the junction has a stop pin that can be inserted into the pin slot when the junction is plugged into the insert hole, and when the junction is plugged into the insert hole, a positioning element is provided for positioning the junction at the shaft base, such that the stop pin drives the ice pressing tray to rotate when the worm shaft rotates.

4. The ice shaver structure of claim 3, wherein the columns are scattered on the second side, and the ice pressing tray is made of plastic, and each column is made of aluminum and has a vertical column section combined into the ice pressing tray and a conical section exposed from the second side.

5. The ice shaver structure of claim 4, further comprising a pressing element for separating a wear resisting plate and attaching on the second side of the ice pressing tray, and the ice pressing tray and the pressing element are coaxially and pivotally coupled with each other by a pivot and pivoted with respect to each other.
