Description

Technical Field

[0001] This utility model relates to the field of reclining chair technology, specifically a shifting structure for a reclining chair. Background Technology

[0002] With economic and technological development, reclining chairs are widely used in various aspects of life. Existing reclining chair structures generally include a seat, backrest, and leg supports. The leg supports directly support the backrest and also anchor the entire reclining chair to the ground. As the application scenarios for reclining chairs expand and the needs of users increase, the backrest of reclining chairs are becoming more adjustable. Existing adjustment mechanisms are typically sliding, flip-up, or button-operated, but these are overly complex and do not allow for a smooth transition between sitting and reclining positions. Therefore, those skilled in the art urgently need to propose improvements. Utility Model Content

[0003] The purpose of this utility model is to provide a shifting structure for a recliner that is compact, easy to use, and aesthetically pleasing.

[0004] This utility model proposes the following technical solution: a shifting structure for a recliner, wherein the shifting structure is slidably disposed on an external connecting member, and the shifting structure includes:

[0005] The fixing module has an axially provided through hole, and the external connector passes through the through hole to form a sliding track;

[0006] A limiting module is movably connected to the fixing module. The movable connection is a first state in which the limiting module controls the fixing module to be fixed on the external connector and a second state in which the limiting module controls the fixing module to slide on the external connector.

[0007] The limiting module includes a limiting member and an elastic member. The limiting member is inserted into the fixing module, and the two ends of the elastic member abut against the fixing module and the limiting member, respectively. The limiting member is also provided with a through hole for connecting an external connector.

[0008] This design allows the fixed module and external connectors to be connected through the sliding and fixing of the limiting module, and the operation is simpler and more convenient than the existing design.

[0009] Specifically, the limiting component includes a first limiting block and a second limiting block. The first limiting block is movably connected to the fixing module and switches between a first state and a second state. The second limiting block protrudes from the bottom of the first limiting block and abuts against the elastic component.

[0010] In this design, the transition between the first state and the second state is achieved through the cooperation of the protruding part between the second limiting block and the first limiting block and the elastic element. Although the protruding part is set on the second limiting block in this utility model, it is not excluded that the protruding part may be set on other parts but the structural principle is the same and the same purpose effect can be achieved. All of these fall within the protection scope of this utility model.

[0011] Specifically, the second limiting block is provided with a protrusion, and the bottom of the first limiting block is provided with a first through hole for the protrusion to pass through; the external connector is also provided with a second through hole that matches the protrusion.

[0012] In this design, both the first and second through holes are matched with protrusions to better lock them into the preset positions, that is, to fix the fixing module to the preset position of the external connector.

[0013] Specifically, in the original state, the protrusion of the second limiting block passes through the bottom of the first limiting block and through the external connector, so the fixing module and the limiting module achieve the first state on the external connector; the first limiting block applies force to the second limiting block to deform the elastic element, so the fixing module drives the limiting module to achieve the second state on the external connector.

[0014] This design allows for smoother sliding during use, more accurate locking of the clips, and is more effortless and convenient to use.

[0015] Specifically, the first limiting block and the second limiting block are integrally formed.

[0016] This design is based on the consideration of making the structure of the first and second limiting blocks more stable.

[0017] Specifically, the first limiting block and the second limiting block are set separately.

[0018] This design is based on the consideration that the second limit block can be replaced according to actual needs, making it easy to replace if damaged and extending the service life of the overall structure.

[0019] Specifically, the second limiting block is made of metal.

[0020] The design uses metal because it is more durable and has a longer lifespan.

[0021] Specifically, the second limiting block is made of plastic.

[0022] The design uses plastic material for easier integrated production, and the second limit block can also be replaced with other materials with similar or identical properties.

[0023] Specifically, the first limiting block is provided with a button part, which is detachably disposed from the first limiting block.

[0024] This design allows the user to apply force to fix the position of the module. The first limiting block is detachable for easy replacement.

[0025] Specifically, at least one fixing bracket extends outward from the outer side wall of the fixing module.

[0026] This design aims to link the shifting mechanism with external connectors, thereby broadening its application range and providing a new linkage connection method. Attached Figure Description

[0041] Please see Figures 1 to 9 As shown, a shifting structure for a recliner is slidably mounted on an external connector 1. The shifting structure includes a fixing module 2 and a limiting module 3. The fixing module 2 and the limiting module 3 are primarily made of plastic, but can also be made of other materials. The fixing module 2 has an axially oriented through hole 21 through which the external connector 1 passes to form a sliding track; the shape of the through hole 21 must match the shape of the external connector 1.

[0042] In this invention, the limiting module 3 is movably connected to the fixing module 2. This movable connection exists in two states: a first state where the limiting module 3 controls the fixing module 2 to be fixed on the external connector 1, and a second state where the limiting module 3 controls the fixing module 2 to slide on the external connector 1. The limiting module 3 includes a limiting member 31 and an elastic member 32. The elastic member 32 in this invention is a part made of a spring or other material that can automatically return to its original shape. The limiting member 31 is inserted into the fixing module 2, and both ends of the elastic member 32 abut against the fixing module 2 and the limiting member 31, respectively. The limiting member 31 also has a through hole 21 for connecting to the external connector 1.

[0043] The limiting component 31 includes a first limiting block 311 and a second limiting block 312, wherein the first limiting block 311 and the second limiting block 312 are integrally formed or separately disposed. The second limiting block 312 is made of metal or plastic.

[0044] The first limiting block 311 is movably connected to the fixed module 2, switching between a first state and a second state; the second limiting block 312 protrudes from the bottom of the first limiting block 311, and the second limiting block 312 abuts against the elastic member 32. The second limiting block 312 is provided with a protrusion 3122, and the bottom of the first limiting block 311 is provided with a first through hole 3111 through which the protrusion 3122 passes; the external connecting member 1 is also provided with a second through hole that matches the protrusion 3122 (not shown in the attached figure but does not affect the understanding).

[0045] The first limiting block 311 is provided with a button part 3112, which is detachable from the first limiting block 311 for easy replacement. At least one fixing bracket 211 extends outward from the outer wall of the fixing module 2. The backrest height of the recliner is adjusted by connecting the fixing bracket 211 with other external connectors 1. The angle between the fixing module 2 and the limiting module 3 relative to the external connectors 1, combined with the angle adjustment of the fixing bracket 211, can be adjusted to a comfortable control direction for the user.

[0046] During operation, in the original state, the protrusion 3122 of the second limiting block 312 passes through the bottom of the first limiting block 311 and through the external connector 1, so the fixing module 2 and the limiting module 3 achieve the first state on the external connector 1; the first limiting block 311 exerts force on the second limiting block 312 to deform the elastic member 32, so the fixing module 2 drives the limiting module 3 to achieve the second state on the external connector 1.

[0047] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
