Description

Technical Field

[0001] This utility model relates to the field of teaching equipment technology, specifically to a slide rail with hidden buffer damping and a push-pull smart blackboard. Background Technology

[0002] The smart blackboard includes a main frame and a sliding sub-board mounted on the main frame. A slider is mounted on the outer frame of the sub-board, and the slider slides in conjunction with a slide rail on the main frame. To limit the movement of the sub-board, existing technology uses limit blocks at both ends of the slide rail to block the slider, thereby limiting the range of movement of the sub-board. However, in actual use, the design method of using limit blocks to block the slider requires teachers to move the sub-board very carefully. Even a slight force will cause the sub-board to violently hit the limit blocks of the main frame, resulting in loud noise and affecting the overall lifespan of the smart blackboard. Utility Model Content

[0003] To address the technical problem of the lack of sliding damping design in the push-pull sub-plate of existing smart blackboards, this application proposes a slide rail with hidden buffer damping and a push-pull smart blackboard, thus solving the aforementioned technical problem.

[0004] The technical solution adopted by this utility model to solve its technical problem is:

[0005] This utility model provides a slide rail with concealed buffer damping, including a damping strip and a slide rail. The damping strip is fixedly connected to or integrally formed with a limiting block on the slide rail. At the same time, the damping strip is laid flat on the track surface of the slide rail, and contacts the side of the slider that is matched on the slide rail before the limiting block, and is inserted into the gap between the slider and the slide rail.

[0006] Furthermore, the damping strip includes a guide section and a straight section, one end of the straight section is connected to the limiting block, and the other end of the straight section is connected to the guide section. The guide section forms a gradually thinning slope starting away from the straight section.

[0007] Furthermore, the width of the damping strip is narrower than the width of the limiting block.

[0008] Furthermore, the damping strip is made of a non-metallic material and has a rough surface.

[0009] This utility model also provides a push-pull smart blackboard, comprising: the aforementioned slide rail with concealed buffer damping; a push-pull sub-plate, on which the slider is fixed.

[0010] Furthermore, the slide rail is mounted on the main frame.

[0011] Furthermore, the slide rail includes a sliding base plate and L-shaped baffles disposed on both sides of the sliding base plate. The sliding base plate and the two L-shaped baffles enclose the assembly space and contain and limit the slider. Correspondingly, sliding portions adapted to the inner groove shape of the L-shaped baffles are formed on both sides of the slider in the width direction.

[0012] Furthermore, a raised groove is formed at the center of the bottom of the slider to create a gap at the mating point between the slider and the slide rail for the damping strip to engage.

[0013] Furthermore, a protrusion is formed in the center of the sliding base plate of the slide rail, and the protrusion is held in the middle by the two sliding parts of the slider.

[0014] Based on the above technical solution, the technical effects that this utility model can achieve are as follows:

[0015] This utility model features a concealed buffer damping slide rail with a simple structure and low cost. It only requires the addition of a damping strip to the limiting block. The damping strip engages with the gap between the slider and the slide rail before the slider hits the limiting block. The damping strip generates friction with the side of the slider, reducing the potential energy of the slider hitting the limiting block. Simply adding this damping strip to the limiting block of the smart blackboard can provide damping buffer for the push-pull sub-plate of the smart blackboard, reducing the impact noise of the push-pull sub-plate, and also facilitating the pushing and moving operation of teachers without having to worry about the moving force.

The damping strip 1 is fixed to the limiting block 3 on the slide rail 2 and is located at the end that can be hit by the slider 4 that is fitted on the slide rail 2. At the same time, the damping strip 1 is laid flat on the track surface of the slide rail 2, contacts the side of the slider 4 before the limiting block 3, and is inserted into the gap between the slider 4 and the slide rail 2.

[0022] In a specific embodiment of this utility model, the damping strip 1 includes a guide section 11 and a straight section 12. One end of the straight section 12 is connected to the limiting block 3, and the other end of the straight section 12 is connected to the guide section 11. The guide section 11 gradually thins out from away from the straight section 12 to guide the slider 4.

[0023] In one specific embodiment of this utility model, the width of the damping strip 1 is narrower than the width of the limiting block 3, which facilitates the modification of the existing smart blackboard.

The main frame 5 is equipped with a slide rail 2, the slide rail 2 is equipped with a limit block 3, the limit block 3 is equipped with a damping strip 1, and the push-pull sub-plate 6 is fixed with a slider 4, which is slidably engaged with the slide rail 2 of the main frame 5 through the slider 4.

[0026] In a preferred embodiment of the present invention, the slide rail 2 includes a sliding base plate 21 and L-shaped baffles 22 disposed on both sides of the sliding base plate 21. The assembly space enclosed by the sliding base plate 21 and the two L-shaped baffles 22 accommodates and limits the slider 4. Correspondingly, sliding portions 41 adapted to the inner groove shape of the L-shaped baffles 22 are formed on both sides of the slider 4 in the width direction.

[0027] In a preferred embodiment of the present invention, a raised groove 42 is formed in the center of the bottom of the slider 4 to form a gap for the damping strip 1 to be inserted at the mating point of the slider 4 and the slide rail 2.
