Description

Technical Field

[0001] The utility model relates to the technical field of slide rail systems, in particular to a press-fastening 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 wooden and steel drawers of cabinets, furniture, document cabinets, bathroom cabinets, refrigerators, etc. For example, the slide rail of the drawer inside the refrigerator is mainly responsible for supporting the drawer and allowing the drawer to be smoothly pulled out and pushed in, so as to increase the convenience for users to pick up and place food.

[0003] For example, in the Chinese patent with the publication number of CN106037297A, a synchronous drawer slide rail system with a sound-absorbing and rebounding function is provided. 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 assemblies, and the two groups of slide rail assemblies 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 one side surface of the housing component facing the drawer. The slide rail assembly is installed in the linear concave groove. A horizontal extension plate extending towards the drawer side is provided at 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. A slide rail rebounding mechanism is installed in the groove, which can solve the problems of large space occupation rate and low load-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. However, when a single slide rail is damaged and needs to be replaced, the connection of the connecting rod still needs to be released by screws. During installation or disassembly, a specific tool is required to disassemble the screws. After releasing the fixation of the screw on the connecting part of the connecting rod, the single slide rail can be disassembled, which is relatively troublesome. Summary of the Utility Model

[0022] In order to more clearly understand the technical means of the present utility model and be implemented 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 not to limit the scope of the present utility model.

[0023] See the attached Figure 1-2 As shown, a press - button snap - type tool - free disassembly and assembly synchronous connecting rod mechanism for a thin slide rail includes a transmission gear 1 meshing with a rack on the inner rails of the inner sides of the thin slide rails at both left and right ends; a connection slot 103 is opened at the rear end of the transmission gear 1, and a synchronous connecting rod 3 is detachably arranged inside the connection slot 103. The synchronous connecting rod 3 is designed in a hollow shape. A card slot 101 is opened at the rear end of the upper surface of the transmission gear 1, and a press - button fastener 2 adapted to the card slot 101 is arranged inside the synchronous connecting rod 3. An activity slot for the horizontal sliding of the press - button fastener 2 is opened at the rear end of the upper surface of the synchronous connecting rod 3. By manually sliding the press - button fastener 2, the press - button fastener 2 can horizontally slide inside the cavity of the synchronous connecting rod 3.

[0024] A chamfering slot for guiding the press - button fastener 2 is opened at the rear end of the upper surface of the transmission gear 1. By providing the chamfering slot, when the synchronous connecting rod 3 is inserted into the inside of the transmission gear 1 and the press - button fastener 2 is pushed forward, the chamfering slot squeezes the head of the press - button fastener 2, so that the press - button fastener 2 can be pressed down.

[0025] Such as Figure 3-4As shown, the front end of the lower surface of the push buckle 2 is provided with an arc-shaped elastic member 203 that can provide supporting force for the push buckle 2, the bottom of the arc-shaped elastic member 203 is in sliding contact with the inner wall of the synchronous connecting rod 3, and a fixing seat 202 is provided on the lower surface of the push buckle 2 and at the rear end of the arc-shaped elastic member 203, and the front end of the upper surface of the push buckle 2 is provided with a limit block 205 that can be used with the card slot 101, the height of the pressing portion 201 is higher than the limit block 205, the front end of the limit block 205 is designed to be inclined, and the angle between the rear end of the limit block 205 and the upper surface of the push buckle 2 is 90°, the height of the pressing portion 201 is greater than the design of the limit block 205, so that the pressing portion 201 protrudes from the surface of the synchronous connecting rod 3, and the upper surface of the push buckle 2 is provided with a pressing portion 201, and the rear end of the pressing portion 201 is provided with an extension portion 204.

[0026] There are two extension parts 204 at the tail of the pressing part 201, and the two extension parts 204 and the tail end of the pressing buckle 2 form a concave tail. In actual use, when it is inconvenient to push the pressing buckle 2 to move inward due to special circumstances or angles, a push rod can be used to push the rear end of the pressing buckle 2 to move the pressing buckle 2 forward, and then the front end of the limit block 205 cooperates with the inclined groove at the rear end of the upper surface of the transmission gear 1, so that the pressing buckle 2 produces a downward movement under force.

[0027] By setting the arc-shaped elastic member 203, when the pressing part 201 is pressed downward, the arc-shaped elastic member 203 is deformed by the pressure, so that the pressing buckle 2 moves downward as a whole, and then pushes the pressing buckle 2 forward, so that the pressing buckle 2 drives the limiting block 205 to move to the card slot 101. When the pressing buckle 2 is released, the arc-shaped elastic member 203 will reset according to its own elasticity and push the limiting block 205 to move upward to the inside of the card slot 101. When the limiting block 205 moves to the inside of the card slot 101, the fixation is completed. When disassembling, press the pressing part 201, so that the pressing part 201 drives the limiting block 205 to be pressed downward, and slide the pressing buckle 2 backward to make the limiting block 205 detach from the inside of the card slot 101.

[0028] according to Figure 5 As shown, a protrusion 102 is provided at the rear end of the transmission gear 1, and a transmission gear connected to the slide rail is provided at the front end of the transmission gear 1. The setting of the protrusion 102 is convenient for the staff to identify the front and back sides of the transmission gear 1, so that the position of the press buckle 2 and the slot 101 are parallel during installation.

[0029] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the technical principle of the present invention, and these improvements and modifications should also be regarded as within the protection scope of the present invention.
