Description

Technical Field

[0001] This utility model relates to the technical field of guiding mechanisms, specifically a pull-out synchronous guiding mechanism. Background Technology

[0002] Pull-out guide mechanisms are used for drawers or similar pull-out guide devices and are applicable to furniture, filing cabinets, kitchen cabinets, bathroom cabinets, electromechanical cabinets, heavy-duty refrigerators, etc.

[0003] The existing pull-out guide mechanism has an upper rail, a lower rail, and a middle rail. The lower rail is fitted onto the lower part of the middle rail and a support plane is installed thereon. The upper rail is fitted onto the upper part of the middle rail and a support plane is installed thereon.

[0004] However, the pull-out guide mechanism described above has the following shortcomings in practical applications:

[0005] 1) In the existing pull-out guide mechanism, the upper rail and the middle rail do not operate synchronously during opening and closing, resulting in poor sliding of the guide mechanism, poor transmission stability, and even jamming, which seriously affects the normal use of the product.

[0006] 2) During the opening and closing process, the middle rail of the existing pull-out guide mechanism will sway left and right and collide with the upper and lower rails, which will generate a lot of noise, reduce the user experience, and easily damage the product, thus reducing its service life.

[0007] 3) If a synchronous operation mechanism with rack and pinion is added to the existing pull-out guide mechanism, the structure will be complex, occupy a large space, resulting in a large product size and greater limitations in use. Utility Model Content

[0008] The purpose of this invention is to overcome the shortcomings of the prior art and provide a pull-out synchronous guide mechanism with a simple structure, which can reduce space occupation, reduce product size, improve synchronization performance, enhance operational stability, reduce shaking during operation, strengthen transmission stability, and ensure product quality.

[0009] The objective of this invention is achieved as follows: A pull-out synchronous guiding mechanism includes an upper rail body, a lower rail body, and a middle rail body movably supported between the upper and lower rail bodies. The middle rail body is equipped with a synchronous running device for synchronous operation between the rail bodies. The synchronous running device includes an upper fixing component, a lower fixing component, a transmission component, a front transmission wheel, and a rear transmission wheel. The upper fixing component is installed on the upper rail body, and the lower fixing component is installed on the lower rail body. The front and rear transmission wheels are respectively installed at the front and rear ends of the middle rail body. The transmission component is fixedly connected to the upper and lower fixing components, and the front and rear ends of the transmission component are respectively wound around the front and rear transmission wheels.

[0010] Based on the above optimization, the upper fixing component includes an upper fixing frame and an upper transmission fixing component. The upper fixing frame is installed on the upper rail body, the upper transmission fixing component is detached from and installed on the upper fixing frame, and the upper connecting part of the transmission component is fixedly connected to the upper transmission fixing component.

[0011] Based on the above optimization, the upper transmission fixing member has an upper fixing mounting hole for the upper connecting part of the transmission member to pass through and for fixing the upper connecting part of the transmission member.

[0012] Based on the above optimization, the upper fixing frame includes an upper fixing plate fixedly installed on one side of the upper rail body and an upper fastening position formed by bending the upper fixing plate. The upper transmission fixing component is installed and removed in the upper fastening position. The upper fastening position is provided with upper support connecting parts for supporting the upper connecting part of the transmission component on both sides.

[0013] Based on the above optimization, the lower fixing component includes a lower fixing frame and a lower transmission fixing member. The lower fixing frame is installed on the lower rail body, the lower transmission fixing member is detached from and installed on the lower fixing frame, and the lower connecting part of the transmission member is fixedly connected to the lower transmission fixing member.

[0014] Based on the above optimization, the lower transmission fixing member has a lower fixing mounting hole for the lower connecting part of the transmission member to pass through and for fixing the lower connecting part of the transmission member.

[0015] Based on the above optimization, the lower fixing frame includes a lower fixing plate fixedly installed on one side of the lower rail body and a lower fastening position formed by bending the lower fixing plate. The lower transmission fixing component is installed and removed in the lower fastening position. The lower fastening position is provided with lower support connecting parts for supporting the lower connecting part of the transmission component on both sides.

[0016] Based on the above optimization, the transmission component is set as a steel wire rope.

[0017] Based on the above optimization, both the front drive wheel and the rear drive wheel are configured as drive groove wheels that rotate on one side of the middle rail body.

[0018] The advantages of this utility model are:

[0019] 1) By adding a synchronous operation device, the structure of the upper fixed component, lower fixed component, transmission component, front transmission wheel and rear transmission wheel of the device is simplified, space is reduced and product volume is reduced. During opening and closing, the middle rail body is pulled outward or pushed inward, which can drive the upper rail body to run synchronously, so that the pull-out synchronous guide mechanism opens and closes in sequence, improving synchronization performance and strengthening transmission stability.

[0020] 2) With the structure of the synchronous operation device, during operation, the transmission components can be connected to the front and rear transmission wheels by friction transmission respectively, ensuring the synchronous operation during opening and closing, reducing shaking during operation, enhancing transmission stability, and ensuring the quality of product use.

[0025] The present invention will now be further described with reference to the accompanying drawings.

[0026] According to the appendix Figures 1 to 4 As shown, the pull-out synchronous guiding mechanism of this utility model includes an upper rail body 1, a lower rail body 2, and a middle rail body 3 movably supported between the upper rail body 1 and the lower rail body 2. The middle rail body 3 is equipped with a synchronous running device for synchronous operation between the rail bodies. The synchronous running device includes an upper fixing component 4, a lower fixing component 5, a transmission component 6, a front transmission wheel 7, and a rear transmission wheel 8. The upper fixing component 4 is mounted on the upper rail body 1, the lower fixing component 5 is mounted on the lower rail body 2, the front transmission wheel 7 and the rear transmission wheel 8 are respectively mounted at the front and rear ends of the middle rail body 3, and the transmission component 6 is fixedly connected to the upper fixing component 4 and the lower fixing component 5, with the front and rear ends of the transmission component 6 respectively wrapped around the front transmission wheel 7 and the rear transmission wheel 8.

[0027] Since the upper fixed component 4 and the lower fixed component 5 are fixedly connected to the transmission component 6, and the front transmission wheel 7 and the rear transmission wheel 8 are frictionally connected to the transmission component 6, when the product drawer is pulled, the upper rail 1 moves outward, causing the upper fixed component 4 to drive the transmission component 6 to move. Under the action of friction, the upper rail 1 and the middle rail 3 move outward synchronously. When pulled to a specific position, under sufficient pulling force, the upper fixed component 4 of the upper rail 1 drives the transmission component 6 to move towards the front transmission wheel 7, so that the upper rail 1 opens outward relative to the middle rail 3, achieving full opening of the guide mechanism. This enhances the synchronization of the guide mechanism, reduces the initial friction of the mechanism, and makes the product drawer easier to open.

[0028] When the product drawer is pushed, the upper rail 1 moves inward under the pushing force, causing the upper fixed part to drive the transmission part 6 to move towards the rear transmission wheel 8, causing the upper rail 1 to retract onto the middle rail 3. Subsequently, under the frictional force between the transmission part 6 and the front transmission wheel 7 and the rear transmission wheel 8, the upper rail 1 and the middle rail 3 move inward synchronously and retract into the lower rail 2, achieving the closure of the guide mechanism. This ensures the smoothness and sealing of the product drawer when closed, improving the product's usability, safety, and durability.

[0029] Reference Figures 1 to 4 As shown in the diagram, further detailed, the upper fixing assembly 4 includes an upper fixing frame 41 and an upper transmission fixing member 42. The upper fixing frame 41 is mounted on the upper rail body 1, the upper transmission fixing member 42 is detached from and mounted on the upper fixing frame 41, and the upper connecting part of the transmission member 6 is fixedly connected to the upper transmission fixing member 42.

[0030] Furthermore, the lower fixing assembly 5 includes a lower fixing frame 51 and a lower transmission fixing member 52. The lower fixing frame 51 is installed on the lower rail body 2, the lower transmission fixing member 52 is detached from and installed on the lower fixing frame 51, and the lower connecting part of the transmission member 6 is fixedly connected to the lower transmission fixing member 52.

[0031] The upper transmission fixing member 42 has an upper fixing mounting hole 43 for the upper connecting part of the transmission member 6 to pass through and for fixing the upper connecting part of the transmission member 6. The lower transmission fixing member 52 has a lower fixing mounting hole 53 for the lower connecting part of the transmission member 6 to pass through and for fixing the lower connecting part of the transmission member 6.

[0032] Furthermore, the upper fixing frame 41 includes an upper fixing plate 411 fixedly installed on one side of the upper rail body 1 and an upper fastening position 412 formed by bending the upper fixing plate 411. The upper transmission fixing member 42 is installed and removed within the upper fastening position 412, and upper support connecting parts 413 for supporting the upper connecting part of the transmission member 6 are respectively provided on both sides of the upper fastening position 412. The lower fixing frame 51 includes a lower fixing plate 511 fixedly installed on one side of the lower rail body 2 and a lower fastening position 512 formed by bending the lower fixing plate 511. The lower transmission fixing member 52 is installed and removed within the lower fastening position 512, and lower support connecting parts 513 for supporting the lower connecting part of the transmission member 6 are respectively provided on both sides of the lower fastening position 512.

[0033] The upper fixing component 4 and lower fixing component 5 using this structure are simple in structure, easy to assemble, reduce the space occupied, and at the same time strengthen the connection between them and the transmission component 6, ensuring the synchronous operation of the guiding mechanism.

[0034] Furthermore, the transmission component 6 is a steel wire rope; the front transmission wheel 7 and the rear transmission wheel 8 are both transmission groove wheels that rotate on one side of the middle rail body 3.

[0035] In this way, during operation, the wire ropes can be connected to the front drive wheel 7 and the rear drive wheel 8 through friction transmission, ensuring the synchronization of operation during opening and closing, while strengthening the connection stability, reducing shaking during operation, enhancing transmission stability, and ensuring the quality of product use.

[0036] The above specific embodiments are only specific implementations of the present utility model with better effects. All structures that are the same as or equivalent to the pull-out synchronous guide mechanism of the present utility model are within the protection scope of the present utility model.
