Description

Technical Field

[0001] This utility model relates to a door closing buffer technology, specifically a sliding door anti-detachment buffer. Background Technology

[0002] Sliding door systems are widely used in homes, offices, and public facilities, with their core function being to achieve smooth opening and closing of the door. To improve the user experience, existing technologies typically incorporate dampers in sliding door systems to slow down the closing speed and prevent impacts and noise. However, the sliders in existing dampers usually achieve their sliding and resetting functions through the cooperation of guide rails and tripping rails. However, when subjected to external vibrations such as door shaking or ground vibrations, the sliders can easily accidentally reset from the tripping rails, causing the damper to lose its automatic buffering function when the sliding door closes. For example, when the sliding door is half-open, vibration may cause the slider to disengage from the tripping rails and reset directly to the guide rails, thus causing the sliding door to lose its buffering effect when closing, resulting in impacts and noise.

[0003] To address the issue of unexpected slider reset, some buffers employ complex mechanical structures such as additional locking devices or spring-loaded limiting mechanisms. However, these structures not only increase manufacturing costs but also reduce the reliability of the device. For example, complex locking devices are prone to wear or jamming after prolonged use, causing the buffer to malfunction.

[0004] Therefore, the buffering effect of existing buffers is greatly affected by the slider position and motion state, and it is necessary to make further improvements to them. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a sliding door anti-detachment buffer that is simple in structure, easy to use, and can effectively improve the stability of the door closer.

[0006] The purpose of this utility model is achieved through the following means: a sliding door anti-detachment buffer, which includes a main body, a sliding groove and a receiving groove are provided on the main body, a guide rail and a release rail are provided on the side wall of the sliding groove, a slider is slidably installed in the sliding groove, a moving block and a guide block are provided on the slider, the moving block extends into the guide rail and slides, and the guide block slides in the guide rail or the release rail.

[0007] A buffer is installed in the receiving groove, and the piston rod of the buffer extends into the sliding groove and is connected to the slider.

[0008] The main body is also equipped with a tension spring, one end of which is connected to the main body and the other end is connected to the slider. The tension spring pulls the slider to move in the closing direction.

[0009] The guide rail extends horizontally in a straight line, and the release rail is set at the end of the guide rail and is inclined to the extension direction of the guide rail.

[0010] The release track has an anti-disengagement groove recessed on the side wall facing the guide track, and the guide block is fixed in the anti-disengagement groove;

[0011] When the slider slides in the closing direction, the guide block is reset from the release track to the guide track via the anti-disengagement groove.

[0012] Furthermore, the anti-disengagement groove is located on the side wall of the release track facing the guide track and intersects with the bottom of the release track.

[0013] Furthermore, the release track and the guide track are connected by an arc connecting track, the radius of which is greater than the width of the guide block.

[0014] Furthermore, the width A of the release track is set to be greater than the width B of the guide track.

[0015] Furthermore: two guide rails and a release rail are provided, which are symmetrically distributed on the two side walls of the sliding groove; guide blocks are symmetrically provided on both sides of the slider, which cooperate with the two guide rails and the release rail respectively.

[0016] The beneficial effects of this utility model are: 1. Simple structure, low production cost, and improved market competitiveness.

[0017] 2. In this utility model, an anti-disengagement groove is recessed on the side wall of the release track facing the guide track, and the guide block is fixed in the anti-disengagement groove. This recessed anti-disengagement groove design effectively enhances the locking force and stability of the slider, so that even when the door is subjected to external force vibration, the guide block can still be firmly locked in the anti-disengagement groove, avoiding accidental disengagement.

[0018] 3. Through the anti-detachment design, this utility model ensures that the sliding door can still maintain the automatic buffer reset function of the buffer when it is closed, and the function will not fail due to the accidental reset of the slider. Attached Figure Description

[0025] The present invention will be further described in detail below with reference to the accompanying drawings. A sliding door anti-derailment buffer includes a main body 1, on which a sliding groove 2 and a receiving groove 3 are provided. The side wall of the sliding groove 2 is provided with a guide rail 21 and a release rail 22 that are interconnected. A slider 4 is slidably installed in the sliding groove 2. The slider 4 is provided with a moving block 41 and a guide block 42. The moving block 41 extends into the guide rail 21 and slides, and the guide block 42 slides within the guide rail 21 or the release rail 22.

[0026] A buffer 5 is installed in the receiving groove 3, and the piston rod 51 of the buffer 5 extends into the sliding groove 2 and is connected to the slider 4.

[0027] The main body 1 is also provided with a tension spring 6. One end of the tension spring 6 is connected to the main body 1, and the other end is connected to the slider 4. The tension spring 6 pulls the slider 4 to move in the closing direction.

[0028] The guide rail 21 extends horizontally in a straight line, and the release rail 22 is set at the tail of the guide rail 21 and is inclined to the extension direction of the guide rail 21.

[0029] The release track 22 has an anti-disengagement groove 23 recessed on one side wall facing the guide track 21, and the guide block 42 is fixed in the anti-disengagement groove 23.

[0030] When slider 4 slides in the closing direction, guide block 42 is reset from release track 22 to guide track 21 via anti-disengagement groove 23.

[0031] In one embodiment: the anti-disengagement groove 23 is located on the side wall of the release track 22 facing the guide track 21, and is intersecting with the bottom of the release track 22.

[0032] In one embodiment: the release rail 22 and the guide rail 21 are connected by an arc connecting rail 24, the radius of the arc of the arc connecting rail 24 being greater than the width of the guide block 42.

[0033] In one embodiment, the width A of the release track 22 is set to be greater than the width B of the guide track 21.

[0034] In one embodiment: two guide rails 21 and two release rails 22 are provided, which are symmetrically distributed on the two side walls of the sliding groove 2; guide blocks 42 are symmetrically provided on both sides of the slider 4, which cooperate with the two guide rails 21 and the release rails 22 respectively.

[0035] Working Principle: Traditional sliding door dampers suffer from the problem that the slider can easily accidentally reset itself from the release guide rail when subjected to vibration. In this invention, the release rail 22 has an indented anti-disengagement groove 23 on the side wall facing the guide rail 21, and the guide block 42 is fixedly engaged within this anti-disengagement groove 23. This indented anti-disengagement groove design effectively enhances the locking force and stability of the slider, ensuring that even when the door is subjected to external vibration, the guide block remains firmly engaged within the anti-disengagement groove, preventing accidental disengagement.

[0036] By employing an anti-disengagement design, this invention ensures that when the sliding door is closed, the slider can only disengage from the trip track and hook onto the trigger when the trigger strikes the slider. The slider then pulls the sliding door via the trigger to achieve an automatic buffer reset function. In other words, in non-operating conditions, the slider will not malfunction due to accidental reset.

[0037] Meanwhile, the concave anti-detachment design solves a common problem in existing technologies without increasing complexity, avoiding the need for additional guiding devices or locking mechanisms added to enhance buffer stability in traditional methods. This not only simplifies the overall structure, reduces manufacturing costs and maintenance difficulty, but also improves the reliability and durability of the system.

[0038] Due to its robust anti-derailment design, this invention significantly reduces door instability during accidental opening or closing, effectively improving the safety and ease of use of the sliding door system. It is particularly suitable for public places or commercial environments with frequent opening and closing.

[0039] In summary, the sliding door anti-detachment buffer of this utility model effectively solves the problem of accidental slider reset under vibration conditions in traditional buffers through innovative anti-detachment groove design, and has significant technical advantages and application prospects.
