In the figure, 1, a support seat; 2. a through hole; 3. a jack; 4. a clamping member; 5. a first weight-reducing slot; 6. an extension plate; 7. a channel is arranged in a penetrating way; 8. a limiting groove; 9. a limiting block; 10. a circular arc plate; 11. an extension plate; 12. a second weight-reducing slot.

Detailed Description

The following are specific embodiments of the present invention and are further described with reference to the drawings, but the present invention is not limited to these embodiments.

As shown in fig. 1-3, a sliding seat is characterized by comprising a supporting seat 1, through holes 2 for a guide rail to pass through are arranged at two ends of the supporting seat 1, a jack 3 for mounting an optical element is arranged on the supporting seat 1, and a clamping piece 4 for clamping the optical element is connected to the jack 3.

In further detail, the holding member 4 holds the optical element by a frictional force.

The clamping piece 4 clamps the optical element through friction force, so that people can conveniently adjust the height of the optical element.

In more detail, the supporting seat 1 is provided with a first lightening groove 5, and the clamping piece 4 is positioned in the first lightening groove 5.

The first weight reduction groove 5 is arranged to reduce the weight of the supporting seat 1, production cost is reduced, and the clamping piece 4 is arranged in the first weight reduction groove 5 to prevent the clamping piece 4 from being affected by the outside.

In further detail, the clamping piece 4 comprises two extension plates 6, the two extension plates 6 are symmetrically arranged on two sides of the insertion hole 3, and the two extension plates 6 are matched with the insertion hole 3 to form a penetrating channel 7 for the insertion rod of the optical element to penetrate.

The extension plate 6 can increase the contact area with the inserted rod of the optical element and increase the friction force, so that the optical element can be stably fixed on the support seat 1.

In a further elaboration, two ends of the insertion hole 3 are provided with limiting grooves 8, and the limiting grooves 8 are used for inserting and fixing limiting blocks 9 symmetrically arranged at two ends of the insertion rod of the optical element.

This setting is used for restricting optical element's angle, and after optical element's inserted bar inserted jack 3, optical element can aim at light source etc. can guarantee simultaneously that in the experimentation, optical element's angle can not change.

To be more specific, the extension plate 6 is composed of an arc plate 10 and extension plates 11 disposed at both ends of the arc plate 10.

After the insertion rod of the optical element is inserted into the insertion hole 3, the arc plate 10 abuts against the insertion rod of the optical element, and the extension plate 11 abuts against the limit block 9, so that the contact area between the insertion rod of the optical element and the extension plate 6 is increased, and friction is increased.

In further detail, the extension plate 6 is made of a plastic material.

When the inserted bar of optical element inserts the slot, extension plate 6 can be strutted to both sides, adopts plastics not fragile, and when optical element pulled out the slot back, extension plate 6 can resume initial position simultaneously.

In more detail, the two ends of the supporting seat 1 are also provided with second weight-reducing grooves 12.

The provision of the second lightening grooves 12 enables the weight of the support base 1 to be reduced while reducing the production cost.

The specific embodiments described herein are merely illustrative of the spirit of the utility model. Various modifications or additions may be made to the described embodiments or alternatives may be employed by those skilled in the art without departing from the spirit or ambit of the utility model as defined in the appended claims.
