Description

Technical Field

[0001] The utility model relates to the technical field of slide rail structures, in particular to a spring-pushing type tool-free disassembly and assembly synchronous connecting rod mechanism for thin slide rails. Background Art

[0002] A slide rail, also known as a guide rail or a slideway, is a hardware connecting component fixed on the cabinet body of furniture and is used for connecting drawers of furniture and household appliances such as cabinets, furniture, document cabinets, bathroom cabinets, refrigerators, etc. made of wood and steel, such as the slide rail of the internal drawer of a refrigerator. It mainly supports the drawer and allows the drawer to be smoothly pulled out and pushed in, so as to increase the convenience for users when taking and placing food.

[0003] When installing the current thin slide rail, first fix the thin slide rail on the connecting plates on both sides, then install the synchronous linkage component on the slide rail, and connect the two synchronous linkage components through a synchronous connecting rod, so that when one side of the slide rail is forced to move, the other side of the slide rail is driven to move through the synchronous connecting rod.

[0004] For example, in the Chinese patent with the publication number CN106037297B, a synchronous drawer slide rail system with a sound-absorbing and rebounding function is provided, which can solve the problems of large space occupation rate and low bearing capacity of the slide rail in the existing drawer slide rail system due to the damping device of the rebounding mechanism being arranged at the bottom end inside the slide rail. The two outer sides of the drawer are respectively slidably connected to the two inner side walls of the cabinet body through symmetrically arranged slide rail components, and the two groups of slide rail components are synchronously connected through a synchronous mechanism; a housing component is fixedly installed on the inner side wall of the cabinet body, a long linear concave groove extending along the relative sliding direction of the drawer and the cabinet body is formed on the side surface of the housing component facing the drawer, the slide rail component is installed in the linear concave groove, a horizontal extension plate extending towards the drawer is arranged on the bottom surface of the housing component, a rack is arranged at the inner end of the horizontal extension plate, a downward groove is formed between the bottom groove wall of the linear concave groove and the rack, and a slide rail rebounding mechanism is installed in the groove. However, most synchronous connecting rails use bolts to connect the connecting rod and the gear, and then the gear cooperates with the rack to rotate synchronously. However, using screws will cause problems such as when it is necessary to disassemble one side of the slide rail, special tools are required to disassemble the screws first, which is rather troublesome, and repeatedly disassembling the screws will increase the labor intensity of the staff. Content of the Utility Model

[0005] In view of the problems existing in the above-mentioned prior art, the utility model provides a spring-pushing type tool-free disassembly and assembly synchronous connecting rod mechanism for thin slide rails, which has the technical effect of not requiring other tools for disassembly and increasing convenience.

[0006] To solve the above technical problems and achieve the above technical effects, the utility model is realized through the following technical solutions:

[0007] The technical solution of the present utility model is: a spring-pushed tool-free disassembly and assembly synchronous connecting rod mechanism for a thin slide rail, a synchronous connecting rod. A cavity runs through the inside of the synchronous connecting rod. Transmission gears are provided at the outer ends of the synchronous connecting rod. The transmission gears are meshed with the racks on the inner rail of the thin slide rail. Connecting grooves are formed inside both of the two transmission gears. One end of the synchronous connecting rod is slidably provided with an extension component connected to the front transmission gear. The extension component includes a connecting rod extension cylinder. The connecting rod extension cylinder is slidably sleeved on the front end of the synchronous connecting rod. An extension connecting block is fixedly installed at the front end of the connecting rod extension cylinder. The connecting rod extension cylinder is clamped with the inner cavity of the transmission gear through the extension connecting block. A spring support plate is fixedly installed inside the synchronous connecting rod. A connecting rod connecting groove for the horizontal movement of the synchronous connecting rod is formed in the inner wall of the connecting rod extension cylinder. A support spring is horizontally and telescopically arranged between the inner wall of the connecting rod connecting groove and the inner wall of the spring support plate.

[0008] Further, the extension connecting block has the same size as the synchronous connecting rod, and the connecting rod extension cylinder and the transmission gear have the same size.

[0009] Further, silent clamping blocks are provided on the inner walls of both of the two transmission gears.

[0010] Further, silent grooves adapted to the silent clamping blocks are formed on the surfaces of the extension connecting block and the tail end of the transmission gear.

[0011] Further, the silent clamping block is designed to be inclined, and an observation port is formed on the surface of the transmission gear and on one side of the silent clamping block.

[0012] Further, the spring support plate is arranged in an L shape.

[0013] Further, an extension cylinder guide block is provided on one side of the inner wall at the rear end of the connecting rod extension cylinder, and an extension cylinder guide groove adapted to the extension cylinder guide block is formed on one side of the inner wall at the front end of the synchronous connecting rod.

[0014] Further, an L-shaped baffle for assisting in positioning the support spring is provided on the inner wall of the connecting rod connecting groove.

[0015] The beneficial technical effects of the present utility model are as follows: By providing a connecting rod extension cylinder and a support spring, when it is necessary to disassemble a slide rail, slide the connecting rod extension cylinder inward, so that the connecting rod extension cylinder receives the front end of the synchronous connecting rod through the connecting rod connecting groove, and the spring support plate supports the support spring, causing the support spring to contract and generate elastic force while contracting. Subsequently, the extension connecting block in the connecting rod extension cylinder cancels the connection with the transmission gear to release the connection at one end. Then, pull out the rear end of the synchronous connecting rod outward to release the transmission connection between the two slide rails. Subsequently, disassemble the slide rail that needs to be replaced, which increases convenience. There is no need to disassemble the entire slide rail assembly and no need to use other tools for disassembly. The structure is simple, time-saving, and labor-saving.

[0021] In order to be able to more clearly understand the technical means of the present utility model and implement it in accordance with the content of the specification, the following combines the drawings and embodiments to further describe in detail the specific embodiments of the present utility model. The following embodiments are used to illustrate the present utility model but are not used to limit the scope of the present utility model.

[0022] Refer to the attached Figure 1 As shown, a spring push type tool-free disassembly and assembly synchronous connecting rod mechanism for a thin slide rail includes a synchronous connecting rod 1. A cavity runs through the inside of the synchronous connecting rod 1. Transmission gears 3 are provided at the outer ends of the synchronous connecting rod 1. Connecting grooves are provided inside both of the two transmission gears 3. A rack connected to the transmission gear 3 is provided on the inner slide rail inside the thin slide rail. The transmission gear 3 meshes with the rack on the inner rail of the thin slide rail. When one side of the slide rail is stressed and unfolded, the slide rail drives the transmission gear 3 to rotate through the rack plate, and the synchronous connecting rod 1 drives the other side slide rail to move through the transmission gear 3 on the other side, thus realizing synchronous movement.

[0023] One end of the synchronous connecting rod 1 is slidably provided with an extension assembly connected to the front-end transmission gear 3; the extension assembly includes a connecting rod extension cylinder 2, the connecting rod extension cylinder 2 is slidably sleeved on the front end of the synchronous connecting rod 1, and the front end of the connecting rod extension cylinder 2 is fixedly installed with an extension connecting block 202. The extension connecting block 202 has the same size as the synchronous connecting rod 1, and the connecting rod extension cylinder 2 and the transmission gear 3 have the same size. The connecting rod extension cylinder 2 is clamped with the inner cavity of the transmission gear 3 through the extension connecting block 202. A spring support plate 102 is fixedly installed inside the synchronous connecting rod 1. The spring support plate 102 is arranged in an L shape. An L-shaped baffle capable of assisting in positioning the support spring 103 is arranged on the inner wall of the connecting rod connection groove 203. A connecting rod connection groove 203 for the horizontal movement of the synchronous connecting rod 1 is opened on the inner wall of the connecting rod extension cylinder 2. A support spring 103 is horizontally arranged between the inner wall of the connecting rod connection groove 203 and the inner wall of the spring support plate 102 in a telescopic manner.

[0024] By setting the extension assembly, when it is necessary to separately disassemble one side of the slide rail, slide the connecting rod extension cylinder 2 inward, so that the connecting rod extension cylinder 2 receives the front end of the synchronous connecting rod 1 through the connecting rod connection groove 203, and the spring support plate 102 supports the support spring 103, so that the support spring 103 contracts and generates elastic force at the same time. Subsequently, the extension connecting block 202 in the connecting rod extension cylinder 2 cancels the contact with the transmission gear 3 to release the connection at the front end of the synchronous connecting rod 1. Then, pull out the rear end of the synchronous connecting rod 1 to release the transmission connection between the two slide rails, and then disassemble the slide rail that needs to be replaced.

[0025] The connecting rod extension cylinder 2 and the synchronous connecting rod 1 form a folding assembly. After the slide rails on both sides are fixed, the folding assembly can be placed between the two slide rails. Press the connecting rod extension cylinder 2 to make the connecting rod extension cylinder 2 move inward. Then align the connecting rod extension cylinder 2 with the inside of the transmission gear 3 and release the connecting rod extension cylinder 2. The support spring 103 pushes the connecting rod extension cylinder 2 to expand, so that the connecting rod extension cylinder 2 drives the extension connecting block 202 to insert into the inside of the transmission gear 3. While providing auxiliary fixation, it can provide some movable adjustment space for the synchronous connecting rod 1 to have enough space when adjusting the position of the other end of the synchronous connecting rod 1. After inserting the other end of the synchronous connecting rod 1 into the corresponding transmission gear 3 as well, the two transmission gears 3 can be connected. When one side of the slide rail moves, the other side of the slide rail can move synchronously.

[0026] See Appendix Figure 2As shown in the figure, on one side of the inner wall at the rear end of the connecting rod extension cylinder 2, there is an extension cylinder guide block 201. On one side of the inner wall at the front end of the synchronous connecting rod 1, there is an extension cylinder guide groove 101 adapted to the extension cylinder guide block 201. When the connecting rod extension cylinder 2 is sleeved on the front end of the synchronous connecting rod 1 through the connecting rod connection groove 203 and moves, the extension cylinder guide block 201 moves horizontally inside the extension cylinder guide groove 101, so that while the staff observes the moving distance of the connecting rod extension cylinder 2, the moving direction of the connecting rod extension cylinder 2 can be assisted in positioning, so that the connecting rod extension cylinder 2 can only slide horizontally along the surface of the synchronous connecting rod 1.

[0027] See the appendix Figure 3 As shown in the figure, on the inner walls of both of the two transmission gears 3, there are soundproof clamping blocks 301. The soundproof clamping blocks 301 are designed to be inclined, and on the surface of the transmission gear 3 and on one side of the soundproof clamping block 301, there is an observation port. On the surfaces of the extension connection block 202 and the tail end of the transmission gear 3, there are soundproof grooves adapted to the soundproof clamping blocks 301.

[0028] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. It should be pointed out that for those of ordinary skill in the art in this technical field, without departing from the technical principle of the present invention, several improvements and modifications can still be made, and these improvements and modifications should also be regarded as the protection scope of the present invention.
