Abstract
Description
Technical Field
[0001] This utility model relates to the field of slide rail technology, and in particular to a slide rail with a buffer closing mechanism. Background Technology
[0002] A slide rail, also known as a guide rail or slide track, is a mechanical device used to guide and support objects in linear reciprocating motion or motion along a specific trajectory. It usually consists of two or more cooperating parts, one of which is fixed and the other can slide along the track of the fixed part.
[0003] Current drawer slides typically only have the function of opening and closing, without any cushioning measures. When used in drawers or sliding doors, the slider collides directly with the end of the slide after opening or closing to the limit position, which will produce a noticeable collision sound. Furthermore, the impact force generated when closing may cause items (such as fragile tableware, glassware, etc.) to vibrate and collide with each other or fall out of the drawer, resulting in damage to the items. Utility Model Content
[0004] To address the problems existing in the prior art, this utility model provides a slide rail with a buffer closing mechanism, which can buffer the closing when the slide rail is closed, thereby achieving the technical effects of reducing impact force and noise.
[0005] To solve the above-mentioned technical problems and achieve the above-mentioned technical effects, this utility model is implemented through the following technical solution:
[0006] The technical solution of this utility model is: a slide rail with a buffer closing mechanism, including an outer rail, a middle rail slidably connected to the front of the outer rail, an inner rail slidably connected to the front of the middle rail, a rear ball retainer provided at the rear end of the back of the middle rail, a front ball retainer provided at the front end of the front of the middle rail, and a noise-silencing component provided on the surface of the outer rail; a buffer closing component is fixedly installed at the rear end of the bottom of the outer rail, a fixing plate is fixedly installed on the front of the inner rail, and a push plate for use with the buffer closing component is provided on the back of the fixing plate; the buffer closing component includes a mounting plate fixedly connected to the outer rail, a cylinder is provided at the bottom of the mounting plate, a piston rod is provided at the front end of the cylinder, and a limiting block adapted to the push plate is provided at the front end of the piston rod.
[0007] Furthermore, the noise reduction component includes a first rubber component disposed at the front end of the front of the middle rail, and a first baffle adapted to the first rubber component is disposed at the front end and the middle of the back of the inner rail.
[0008] When the inner rail is closed, the rear end of the first baffle contacts the rear end of the first rubber component; when the inner rail is opened, the front end of the first baffle contacts the front end of the first rubber component.
[0009] Furthermore, the noise reduction assembly also includes a second rubber component and a third rubber component disposed on the back of the middle rail and located on both sides of the rear ball bearing retainer, and a second baffle that is adapted to the third rubber component and the second rubber component is provided at both ends of the back of the outer rail.
[0010] When the middle rail is closed, the rear side of the third rubber component contacts the rear end of the second baffle. When the middle rail is extended, the front end of the second rubber component contacts the front end of the second baffle.
[0011] Furthermore, the top of the fixing plate is provided with a connecting groove, and the front of the inner rail is provided with a protrusion that matches the connecting groove. The inner rail is fixedly connected to the connecting groove through the protrusion.
[0012] Furthermore, the mounting plate has a guide groove inside that can guide the limiting block, and guide rods that are adapted to the guide groove are provided on both sides of the upper surface of the limiting block. The front of the limiting block has a limiting groove that can limit the push plate. The rear end of the limiting block is rotatably connected to the front end of the piston rod.
[0013] When the inner rail and the middle rail are closed in sequence, the push plate on the fixed plate will move to the limiting groove in the limiting block and continuously press backward. The limiting block moves inside the guiding groove through the guide rod, so that the limiting block limits the push plate in the limiting groove by rotating.
[0014] Furthermore, the upper surface of the mounting plate is provided with a mounting block, and the lower surface of the outer rail is provided with a slot that matches the mounting block.
[0015] Furthermore, the front ball retainer consists of a first ball and a first retainer, and the inner rail is slidably connected to the middle rail through the front ball retainer.
[0016] Furthermore, the rear ball retainer is composed of a second ball and a second retainer, and the middle rail is slidably connected to the inner rail through the rear ball retainer.
[0017] Furthermore, mounting grooves are provided at both ends of the front side of the inner rail. The workpiece connecting plate is connected to the inner rail through the mounting grooves, and the workpiece is connected to the inner rail through the workpiece connecting plate.
[0018] Furthermore, the outer rail, the middle rail, and the inner rail are of the same length.
[0019] The beneficial technical effects of this utility model are as follows: By setting a silent component, when the slide rail needs to be closed, the inner rail moves backward, and the first baffle on the back of the inner rail makes soft contact with the first rubber part on the middle rail, thus providing initial cushioning. Subsequently, after the middle rail moves backward, the second baffle on the outer rail makes soft contact with the third rubber part on the back of the middle rail, providing secondary cushioning. This avoids direct collision between the ends of the inner rail, middle rail, and outer rail when closing or opening, reducing noise. At the same time, the cooperation between the push plate and the buffer closing component can further reduce the impact force when the slide rail is fully closed, preventing items (such as fragile tableware, glassware, etc.) from being vibrated and colliding with each other or falling out of the drawer due to the impact force generated when the slide rail is closed, thus avoiding damage to the items.

[0030] In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, the specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.
[0031] See appendix Figures 1-8 As shown, a slide rail with a buffer closing mechanism includes an outer rail 1, a middle rail 2 slidably connected to the front of the outer rail 1, and an inner rail 3 slidably connected to the front of the middle rail 2. The outer rail 1, middle rail 2, and inner rail 3 have the same length. A rear ball retainer 21 is provided at the rear end of the back of the middle rail 2, and a front ball retainer 23 is provided at the front end of the front of the middle rail 2. The front ball retainer 23 is composed of a first ball and a first retainer. The inner rail 3 is slidably connected to the middle rail 2 through the front ball retainer 23. The rear ball retainer 21 is composed of a second ball and a second retainer. The middle rail 2 is slidably connected to the inner rail 3 through the rear ball retainer 21.
[0032] The front ball cage 23 and the rear ball cage 21 can reduce the resistance of the inner rail 3 and the middle rail 2 during sliding, making the sliding of the middle rail 2 and the inner rail 3 smoother.
[0033] The top of the fixed plate 4 is provided with a connecting groove 42, and the front of the inner rail 3 is provided with a protrusion that matches the connecting groove 42. The inner rail 3 is fixedly connected to the connecting groove 42 through the protrusion. Both ends of the front of the inner rail 3 are provided with mounting grooves. The workpiece connecting plate 6 is connected to the inner rail 3 through the mounting grooves, and the workpiece is connected to the inner rail 3 through the workpiece connecting plate 6.
[0034] The fixing plate 4 is riveted to the protrusion on the inner rail 3 through the connecting groove 42, without additional accessories, thus reducing costs.
[0035] After the outer rail 1 is fixed to the inner wall of the cabinet, the workpiece connecting plate 6 is fixed on the inner rail 3. Finally, the workpiece is installed on the workpiece connecting plate 6, so that the workpiece can move in the cabinet through the slide rail.
[0036] The outer rail 1 is provided with a noise reduction component. The noise reduction component includes a first rubber part 22 located at the front end of the middle rail 2. The front end and the middle of the back of the inner rail 3 are provided with first baffles adapted to the first rubber part 22. The noise reduction component also includes a second rubber part 24 and a third rubber part 25 located on the back of the middle rail 2 and on both sides of the rear ball retainer 21. The two ends of the back of the outer rail 1 are provided with second baffles adapted to the third rubber part 25 and the second rubber part 24 respectively.
[0037] When the inner rail 3 is closed, the rear first baffle contacts the rear end of the first rubber part 22. When the inner rail 3 is opened, the front first baffle contacts the front end of the first rubber part 22.
[0038] When the middle rail 2 is closed, the rear side of the third rubber part 25 contacts the rear second baffle. When the middle rail 2 is open, the front end of the second rubber part 24 contacts the front second baffle.
[0039] A buffer closing assembly 5 is fixedly installed at the rear end of the bottom of the outer rail 1. A fixing plate 4 is fixedly installed on the front of the inner rail 3. A push plate 41 for use with the buffer closing assembly 5 is provided on the back of the fixing plate 4. The buffer closing assembly 5 includes a mounting plate 52 fixedly connected to the outer rail 1. A mounting block 56 is provided on the upper surface of the mounting plate 52. A slot adapted to the mounting block 56 is opened on the lower surface of the outer rail 1. A cylinder 51 is provided at the bottom of the mounting plate 52. A piston rod 53 is provided at the front end of the cylinder 51. A limiting block 55 adapted to the push plate 41 is provided at the front end of the piston rod 53.
[0040] When the slide rail needs to be closed, the inner rail 3 moves backward, and the first baffle on the back of the inner rail 3 makes soft contact with the first rubber part 22 on the middle rail 2, thus providing initial cushioning. Subsequently, after the middle rail 2 moves backward, the second baffle on the outer rail 1 makes soft contact with the third rubber part 25 on the back of the middle rail 2, providing secondary cushioning. In conjunction with the setting of the buffer closing component 5, when the slide rail is fully closed, the push plate 41 is cushioned by the buffer closing component 5, reducing the impact force and avoiding the problem that the impact force generated when the slide rail is closed may cause items (such as fragile tableware, glass products, etc.) to be vibrated and collide with each other or fall out of the drawer and be damaged.
[0041] The mounting plate 52 has a guide groove 54 inside that can guide the limiting block 55. The upper surface of the limiting block 55 has guide rods 57 on both sides that are adapted to the guide groove 54. The front of the limiting block 55 has a limiting groove that can limit the push plate 41. The rear end of the limiting block 55 is rotatably connected to the front end of the piston rod 53.
[0042] When the inner rail 3 and the middle rail 2 are closed in sequence, the push plate 41 on the fixed plate 4 will move to the limiting groove in the limiting block 55 and continuously press backward. The limiting block 55 moves inside the guide groove 54 through the guide rod 57, so that the limiting block 55 limits the push plate 41 in the limiting groove by rotating.
[0043] When the slide rail needs to be closed, the inner rail 3 moves backward, and the first baffle on the back of the inner rail 3 makes soft contact with the first rubber part 22 on the middle rail 2, thus providing initial cushioning. Subsequently, after the middle rail 2 moves backward, the second baffle on the outer rail 1 makes soft contact with the third rubber part 25 on the back of the middle rail 2, providing secondary cushioning. In conjunction with the setting of the buffer closing component 5, when the slide rail is fully closed, the push plate 41 is cushioned by the buffer closing component 5, which can further reduce the impact force when the slide rail is fully closed. This avoids the problem that the impact force generated when the slide rail is closed may cause items (such as fragile tableware, glass products, etc.) to be vibrated and collide with each other or fall out of the drawer, resulting in damage to the items.
[0044] The first rubber component 22, the second rubber component 24, and the third rubber component 25, together with the first baffle and the second baffle, ensure that both ends of the middle rail 2 are protected by the rubber components when the middle rail 2 and the inner rail 3 are opened or closed. This allows both ends of the middle rail 2 to make soft contact, thereby avoiding direct collision between the ends of the inner rail 3, the middle rail 2, and the outer rail 1, which would cause noise problems. This results in a better user experience when the slide rail is used in furniture, medical facilities, or commercial displays.
[0045] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
