Abstract
Description
Technical Field
[0001] This utility model relates to the field of slide rail structure technology, and in particular to a slide rail structure, drawer structure and refrigeration equipment. Background Technology
[0002] In some devices with drawers, drawers are commonly used for storage. During use, drawers need to be pulled out to retrieve or store items. In many common devices, drawers are sliding, installed via multi-section rails. These rails consist of three stacked metal sections with metal ball bearings between them, and stop points at the ends. During the drawer's movement, the rails slide relative to each other, and the rails are prone to irregular impacts with the stop points, resulting in relatively high noise levels from the sliding rail structure. Utility Model Content
[0003] The main purpose of this utility model is to propose a slide rail structure, a drawer structure, and a refrigeration device, which aims to reduce the noise of the slide rail structure.
[0004] To achieve the above objectives, the present invention proposes a slide rail structure, which includes: The slide rails consist of multiple sections, all extending along a first direction, with adjacent sections capable of sliding relative to each other. The multiple slide rail sections include three adjacently arranged slide rails: a first slide rail, a second slide rail, and a third slide rail. The synchronization component includes a rotating member mounted on the second slide rail, and a first connecting part and a second connecting part that drive the rotating member. The rotational stroke of the rotating member can be converted into the linear movement stroke of the first connecting part and the second connecting part. The first connecting part is located on the first slide rail, and the second connecting part is located on the third slide rail. Under the action of external force, the first slide rail moves in a positive linear direction relative to the second slide rail, thereby driving the first connecting part to move in a positive linear direction, which in turn drives the rotating part to rotate. The rotation of the rotating part causes the second connecting part to move in a negative linear direction relative to the first connecting part, so that the second slide rail moves synchronously in a positive linear direction relative to the third slide rail.
[0005] In one embodiment, the first connecting portion includes a first rack, the second connecting portion includes a second rack, the rotating member includes a rotating gear, and the first rack and the second rack respectively mesh with the opposite two ends of the rotating gear.
[0006] In one embodiment, the rotating component includes two synchronizing rollers, which are spaced apart along the extending direction of the second slide rail. The synchronization assembly also includes a synchronization belt, which is sleeved on the two synchronization rollers and has a first belt segment and a second belt segment opposite to each other on the two synchronization rollers. The first connecting part and the second connecting part are respectively connected to the first belt segment and the second belt segment.
[0007] In one embodiment, the rotating component includes a pulley, and the synchronization assembly further includes a transmission cable wound around the pulley, with the first connecting portion and the second connecting portion respectively located at both ends of the transmission cable; Two synchronization components are provided, and in the two synchronization components, the two transmission cables are respectively wound around the two pulleys on the side that is close to or far from each other.
[0008] In one embodiment, a ball bearing assembly is further provided between two adjacent sections of the slide rail, the ball bearing assembly comprising a plurality of spaced-apart balls; and / or, The ball bearing is made of plastic.
[0009] In one embodiment, the ball assembly includes a retainer having a receiving hole in which the ball is disposed.
[0010] In one embodiment, each of the multiple slide rail sections has a length direction extending along a first direction, a height direction extending along a second direction, and a width direction extending along a third direction, and the multiple slide rail sections are stacked sequentially along the second direction. On the projection along a third direction, the projections of the first slide rail and the third slide rail at least partially overlap.
[0011] In one embodiment, the first slide rail is provided with a first limiting portion to abut against the end of the second slide rail, thereby limiting the maximum overlap length between the first and second slide rails; and / or, A first retainer is provided between the first slide rail and the second slide rail. A second limiting portion is provided on the first slide rail, and a third limiting portion is provided on the second slide rail. The third limiting portion and the second limiting portion are used to abut against the opposite sides of the first retainer to limit the minimum overlap length of the first slide rail and the second slide rail; and / or, A second retainer is provided between the second slide rail and the third slide rail. A fourth limiting part is provided on the second slide rail, and a fifth limiting part is provided on the third slide rail. The fourth limiting part and the fifth limiting part are used to abut against the opposite two sides of the second retainer to limit the minimum overlap length of the second slide rail and the third slide rail.
[0012] This utility model also proposes a drawer structure, including: The shell has a receiving cavity with an opening facing forward; The drawer body is slidably disposed in the receiving cavity; and, The slide rail structure includes the slide rail structure described above, wherein the first slide rail is fixedly disposed on the bottom side wall of the receiving cavity, and the third slide rail is disposed on the outer bottom wall of the drawer body; The slide rail structure includes: The slide rails consist of multiple sections, all extending along a first direction, with adjacent sections capable of sliding relative to each other. The multiple slide rail sections include three adjacently arranged slide rails: a first slide rail, a second slide rail, and a third slide rail. The synchronization component includes a rotating member mounted on the second slide rail, and a first connecting part and a second connecting part that drive the rotating member. The rotational stroke of the rotating member can be converted into the linear movement stroke of the first connecting part and the second connecting part. The first connecting part is located on the first slide rail, and the second connecting part is located on the third slide rail. Under the action of external force, the first slide rail moves in a positive linear direction relative to the second slide rail, thereby driving the first connecting part to move in a positive linear direction, which in turn drives the rotating part to rotate. The rotation of the rotating part causes the second connecting part to move in a negative linear direction relative to the first connecting part, so that the second slide rail moves synchronously in a positive linear direction relative to the third slide rail.
[0013] This utility model also proposes a refrigeration device, including the aforementioned drawer structure; The drawer structure includes: The shell has a receiving cavity with an opening facing forward; The drawer body is slidably disposed in the receiving cavity; and, The slide rail structure includes the slide rail structure described above, wherein the first slide rail is fixedly disposed on the bottom side wall of the receiving cavity, and the third slide rail is disposed on the outer bottom wall of the drawer body; The slide rail structure includes: The slide rails consist of multiple sections, all extending along a first direction, with adjacent sections capable of sliding relative to each other. The multiple slide rail sections include three adjacently arranged slide rails: a first slide rail, a second slide rail, and a third slide rail. The synchronization component includes a rotating member mounted on the second slide rail, and a first connecting part and a second connecting part that drive the rotating member. The rotational stroke of the rotating member can be converted into the linear movement stroke of the first connecting part and the second connecting part. The first connecting part is located on the first slide rail, and the second connecting part is located on the third slide rail. Under the action of external force, the first slide rail moves in a positive linear direction relative to the second slide rail, thereby driving the first connecting part to move in a positive linear direction, which in turn drives the rotating part to rotate. The rotation of the rotating part causes the second connecting part to move in a negative linear direction relative to the first connecting part, so that the second slide rail moves synchronously in a positive linear direction relative to the third slide rail.
[0014] In the technical solution of this utility model, when the first slide rail moves in a positive linear direction relative to the second slide rail, the first connecting part also moves in a positive linear direction relative to the second slide rail. The rotating member rotates to drive the second connecting part to move in a negative linear direction relative to the second slide rail. The third slide rail has a tendency to move in a negative linear direction relative to the second slide rail. The third slide rail applies a positive linear thrust to the second slide rail through the second connecting part to drive the second slide rail to move in a positive linear direction relative to the third slide rail. Thus, when the first slide rail moves in a positive linear direction relative to the second slide rail, the second slide rail moves in a positive linear direction relative to the third slide rail; similarly, when the first slide rail moves in a negative linear direction relative to the second slide rail, the second slide rail moves in a negative linear direction relative to the third slide rail. This achieves the extension and retraction of the slide rail structure, and overall achieves synchronous movement of the first and second slide rails, so that the first and second slide rails slide to the stop position simultaneously, so that the first and second slide rails collide with the corresponding limit points simultaneously, reducing irregular impacts of the slide rails and lowering the noise of the slide rail structure.

[0022] In some devices with drawers, drawers are commonly used for storage. During use, drawers need to be pulled out to retrieve or store items. In many common devices, drawers are sliding, installed via multi-section rails. These rails consist of three stacked metal sections with metal ball bearings between them, and stop points at the ends. During the drawer's movement, the rails slide relative to each other, and the rails are prone to irregular impacts with the stop points, resulting in relatively high noise levels from the sliding rail structure.
[0023] This utility model proposes a slide rail structure.
[0024] Please see Figure 1 , Figure 2 and Figure 3In one embodiment of this utility model, the slide rail structure 100 is used for a refrigeration device. The slide rail structure 100 includes multiple slide rail sections 1 and a synchronization component 2. All multiple slide rail sections 1 extend along a first direction, and adjacent slide rail sections 1 can slide relative to each other. The multiple slide rail sections 1 include a first slide rail 11, a second slide rail 12, and a third slide rail 13 arranged adjacent to each other. The synchronization component 2 includes a rotating member 21 mounted on the second slide rail 12, and a first connecting part 22 and a second connecting part 23 driving and connecting the rotating member 21. The rotational stroke of the rotating member 21 can be converted into the linear movement stroke of the first connecting part 22 and the second connecting part 23. The first connecting part 22 is located on the first slide rail 11, and the second connecting part 23 is located on the third slide rail 13. Under the action of external force, the first slide rail 11 moves in a positive linear direction relative to the second slide rail 12, thereby driving the first connecting part 22 to move in a positive linear direction, which in turn drives the rotating part 21 to rotate. The rotation of the rotating part 21 drives the second connecting part 23 to move in a negative linear direction relative to the first connecting part 22, so that the second slide rail 12 moves synchronously in a positive linear direction relative to the third slide rail 13.
[0025] In the technical solution of this utility model, when the first slide rail 11 moves in a positive linear direction relative to the second slide rail 12, the first connecting part 22 also moves in a positive linear direction relative to the second slide rail 12. The rotating member 21 rotates to drive the second connecting part 23 to move in a negative linear direction relative to the second slide rail 12. The third slide rail 13 has a tendency to move in a negative linear direction relative to the second slide rail 12. The third slide rail 13 applies a positive linear thrust to the second slide rail 12 through the second connecting part 23 to drive the second slide rail 12 to move in a positive linear direction relative to the third slide rail 13. Thus, when the first slide rail 11 moves in a positive linear direction relative to the second slide rail 12, the second slide rail 12 moves in a positive linear direction relative to the third slide rail 13; similarly, when the first slide rail 11 moves in a negative linear direction relative to the second slide rail 12, the second slide rail 12 moves in a negative linear direction relative to the third slide rail 13. The slide rail structure 100 is extended and retracted, and the first slide rail 11 and the second slide rail 12 are synchronized. This allows the first slide rail 11 and the second slide rail 12 to slide to the stop position at the same time, so that the first slide rail 11 and the second slide rail 12 collide with the corresponding limit stop point at the same time. This reduces the irregular impact of the slide rail 1 and lowers the noise of the slide rail structure 100.
[0026] In the multiple slide rails 1, adjacent slide rails 1 can be filled with balls and rollers to reduce friction between connected slide rails 1. Adjacent slide rails 1 can also slide directly in contact, which is not limited here; specifically, balls are provided between adjacent slide rails 1. One of the first slide rail 11 and the third slide rail 13 is fixedly arranged, specifically, the first slide rail 11 is fixedly arranged. The materials of the first slide rail 11, the second slide rail 12, and the third slide rail 13 can be metal or plastic, which is not limited here. Specifically, the first slide rail 11, the second slide rail 12, and the third slide rail 13 are all made of aluminum alloy, which can be easily processed and formed by stamping, cutting, and welding. By making the first slide rail 11, the second slide rail 12, and the third slide rail 13 into metal materials, the strength and service life of the first slide rail 11, the second slide rail 12, and the third slide rail 13 can be guaranteed.
[0027] Please see Figure 1 , Figure 3 and Figure 5 In one embodiment of the present invention, the first connecting portion 22 includes a first toothed rack, and further reference is made to... Figure 3 The second connecting part 23 includes a second rack, and the rotating part 21 includes a rotating gear. The first rack and the second rack respectively mesh with the opposite two ends of the rotating gear.
[0028] When the rotating gear rotates, it simultaneously drives the first rack and the second rack to move in opposite linear directions relative to the rotating gear, so that the first slide rail 11 and the second slide rail 12 move in opposite linear directions relative to the rotating gear. When the first slide rail 11 moves in a positive linear direction relative to the second slide rail 12, the second slide rail 12 moves synchronously in a positive linear direction relative to the third slide rail 13. Conversely, when the first slide rail 11 moves in a negative linear direction relative to the second slide rail 12, the second slide rail 12 moves synchronously in a negative linear direction relative to the third slide rail 13.
[0029] The first rack can be integrally connected or fixed to the first slide rail 11 by any other fixed connection method, such as bonding or bolting, etc., which is not limited here. The first rack can be made of metal or plastic, which is not limited here; specifically, the first rack is made of aluminum alloy, and the first rack and the first slide rail 11 are fixed by bolts.
[0030] The second rack can be integrally connected or fixed to the third slide rail 13 by any other fixed connection method, such as bonding or bolting, which is not limited here. The second rack can be made of metal or plastic, which is not limited here; specifically, the second rack is made of aluminum alloy, and the second rack is fixed to the third slide rail 13 by bolts.
[0031] Please see Figure 8 and Figure 9 In one embodiment of the present invention, the rotating component 21 includes a synchronous roller, two synchronous rollers are provided, and the two synchronous rollers are spaced apart along the extension direction of the second slide rail 12; the synchronous assembly 2 also includes a synchronous belt 24, the synchronous belt 24 is sleeved on the two synchronous rollers, and has a first belt segment 241 and a second belt segment 242 opposite to each other on the two synchronous rollers; the first connecting part 22 and the second connecting part 23 respectively connect the first belt segment 241 and the second belt segment 242.
[0032] When either the first slide rail 11 or the third slide rail 13 moves linearly relative to the second slide rail 12, the corresponding first connecting portion 22 and second connecting portion 23 enable the synchronous belt 24 to drive the synchronous roller to rotate. When the synchronous belt 24 rotates, one of the first belt segment 241 and the second belt segment 242 moves linearly in the forward direction relative to the second slide rail 12, while the other moves linearly in the reverse direction relative to the second slide rail 12. This results in one of the first slide rail 11 and the third slide rail 13 moving linearly in the forward direction relative to the second slide rail 12, while the other moves linearly in the reverse direction relative to the second slide rail 12. Overall, this achieves synchronous linear movement of the second slide rail 12 relative to the third slide rail 13 in the forward direction when the first slide rail 11 moves linearly relative to the second slide rail 12. Similarly, it achieves synchronous linear movement of the second slide rail 12 relative to the third slide rail 13 in the reverse direction when the first slide rail 11 moves linearly in the reverse direction relative to the second slide rail 12. This enables the extension or contraction of the slide rail structure 100.
[0033] The two synchronous roller axes can be arranged in parallel to ensure the stability of the synchronous belt 24 during installation. The first connecting part 22 can be integrally connected to the first slide rail 11 or the synchronous belt 24, which is not limited here; the second connecting part 23 can be integrally connected to the third slide rail 13 or the synchronous belt 24, which is not limited here.
[0034] Please see Figure 10 and Figure 11In one embodiment of the present invention, the rotating component 21 includes a pulley, and the synchronization component 2 further includes a transmission cable 25. The transmission cable 25 is wound around the pulley, and the first connecting part 22 and the second connecting part 23 are respectively provided at both ends of the transmission cable 25. Two synchronization components 2 are provided, and in the two synchronization components 2, the two transmission cables 25 are respectively wound around the two pulleys on the side that is close to or far from each other.
[0035] When one of the first slide rail 11 or the third slide rail 13 moves in a forward linear motion relative to the second slide rail 12, one of the transmission cables 25 can pull the other of the first slide rail 11 or the third slide rail 13 to move in a reverse linear motion relative to the second slide rail 12. When one of the first slide rail 11 or the third slide rail 13 moves in a reverse linear motion relative to the second slide rail 12, the other of the transmission cables 25 can pull the other of the first slide rail 11 or the third slide rail 13 to move in a forward linear motion relative to the second slide rail 12. Overall, it is possible to achieve synchronous movement of the second slide rail 12 relative to the third slide rail 13 in a forward linear motion when the first slide rail 11 moves in a forward linear motion relative to the second slide rail 12. Similarly, when the first slide rail 11 moves in a reverse linear motion relative to the second slide rail 12, the second slide rail 12 moves in a reverse linear motion relative to the third slide rail 13; thus realizing the extension or contraction of the slide rail structure 100.
[0036] The two pulleys are spaced apart along the extension direction of the second slide rail 12, and the two transmission cables 25 are respectively wound around the sides of the two pulleys that are close to each other. The two pulleys can also be coaxially arranged, and the two transmission cables 25 are respectively wound around the opposite sides of the two pulleys.
[0037] Please see Figure 1 , Figure 2 and Figure 7 In one embodiment of this utility model, a ball bearing assembly 3 is further provided between two adjacent sections of the slide rail 1. The ball bearing assembly 3 includes a plurality of spaced-apart balls 31. By providing the ball bearing assembly 3, the balls 31 can be supported between two adjacent sections of the slide rail 1, reducing friction between the two adjacent sections of the slide rail 1. The material of the balls 31 is not limited; the material of the balls 31 can be metal or plastic, and is not limited here. The material of the balls 31 can be set according to actual needs; specifically, in some embodiments, the material of the balls 31 is set to plastic.
[0038] The ball bearing 31 is made of plastic. The ball bearing 31 reduces noise during impact with the slide rail 1, thus reducing the noise of the slide rail structure 100. The ball bearing 31 can also be made of polyoxymethylene (POM).
[0039] Multiple balls 31 are spaced apart, and the stability of the support for the slide rail 1 can be improved by using multiple balls 31.
[0040] Please see Figure 12 , Figure 13 and Figure 14 The ball assembly 3 includes a retainer 32, which has a receiving hole 321 in which the ball 31 is disposed. The retainer 32 can constrain and limit the movement of the ball 31 through the receiving hole 321.
[0041] The two retainers 32 include a first retainer 322 and a second retainer 323. The first retainer 322 is disposed between the first slide rail 11 and the second slide rail 12, and the second retainer 323 is disposed between the second slide rail 12 and the third slide rail 13.
[0042] Please see Figure 2 , Figure 4 and Figure 7 In one embodiment of this utility model, each of the multiple slide rail sections 1 has a length direction extending along a first direction, a height direction extending along a second direction, and a width direction extending along a third direction. The multiple slide rail sections 1 are stacked sequentially along the second direction. In the projection along the third direction, the projections of the first slide rail 11 and the third slide rail 13 at least partially overlap. By setting the dimensions of the first slide rail 11 and the second slide rail 12 so that the projections of the first slide rail 11 and the third slide rail 13 at least partially overlap in the projection along the third direction, the size of the slide rail structure 100 in the second direction is reduced.
[0043] The first slide rail 11 is provided with a first limiting part 111, which abuts against the end of the second slide rail 12 to limit the maximum overlap length of the first slide rail 11 and the second slide rail 12. By abutting the end of the second slide rail 12 against the first limiting part 111, the linear movement of the first slide rail 11 and the second slide rail 12 toward each other can be limited, thereby limiting the maximum overlap length of the first slide rail 11 and the second slide rail 12. The first limiting part 111 can be fixed to the first slide rail 11 by integral connection or other feasible methods, which are not limited here; specifically, the first limiting part 111 is fixed to the slide rail 1 by bolts.
[0044] Please see Figure 2 , Figure 5 and Figure 7In one embodiment of the present invention, a first retainer 322 is provided between the first slide rail 11 and the second slide rail 12. A second limiting part 112 is provided on the first slide rail 11, and a third limiting part 121 is provided on the second slide rail 12. The third limiting part 121 and the second limiting part 112 are used to abut against the opposite two sides of the first retainer 322 to limit the minimum overlap length of the first slide rail 11 and the second slide rail 12.
[0045] When the first slide rail 11 and the second slide rail 12 move along mutually distant straight lines, the third limiting part 121 and the second limiting part 112 are used to abut against the opposite two sides of the first retainer 322, thereby limiting the minimum overlap length of the first slide rail 11 and the second slide rail 12.
[0046] The second limiting part 112 can be integrally connected to the first slide rail 11 or connected in any other feasible manner, which is not limited here; specifically, the second limiting part 112 is integrally formed with the first slide rail 11. The third limiting part 121 is integrally connected to the second slide rail 12 or connected in any other feasible manner, which is not limited here; specifically, the second slide rail 12 is partially cut and bent to form the third limiting part 121.
[0047] Please see Figure 2 , Figure 6 and Figure 7 In one embodiment of the present invention, a second retainer 323 is provided between the second slide rail 12 and the third slide rail 13. A fourth limiting part 122 is provided on the second slide rail 12, and a fifth limiting part 131 is provided on the third slide rail 13. The fourth limiting part 122 and the fifth limiting part 131 are used to abut against the opposite two sides of the second retainer 323 to limit the minimum overlap length of the second slide rail 12 and the third slide rail 13.
[0048] When the second slide rail 12 and the third slide rail 13 move in directions away from each other, the fourth limiting part 122 and the fifth limiting part 131 can respectively abut against the opposite two sides of the second retainer 323 to limit the minimum overlap length of the second slide rail 12 and the third slide rail 13.
[0049] The fourth limiting part 122 can be integrally connected to the second slide rail 12 or connected in any other feasible manner, which is not limited here. The fifth limiting part 131 can be integrally connected to the third slide rail 13 or connected in any other feasible manner, which is not limited here.
[0050] In one embodiment of this utility model, the first limiting part 111 and the second limiting part 112 are respectively disposed at both ends of the first slide rail 11 along its length. The first limiting part 111 and the second limiting part 112 can provide movement space for the first retainer 322.
[0051] The third limiting part 121 and the fourth limiting part 122 are respectively disposed at both ends of the second slide rail 12 along its length. The third limiting part 121 and the fourth limiting part 122 can provide movement space for the second retainer 323.
[0052] This utility model also proposes a drawer structure, which includes a slide rail structure 100. The specific structure of the slide rail structure 100 is as described in the above embodiments. Since this drawer structure adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, and will not be described in detail here. The drawer structure includes a shell, a drawer body, and a slide rail structure 100. The shell forms a receiving cavity with an opening facing forward. The drawer body is slidably disposed in the receiving cavity.
