Description

Technical Field

[0001] The utility model relates to the technical field of chair armrests, in particular to a buckle-type chair armrest. Background Art

[0002] A chair is a kind of daily furniture, a kind of seat with a backrest and armrests. The structure of a chair generally includes: a support leg and a seat cushion connected to the support leg, and a backrest support connected to the seat cushion or the support leg. The backrest support is equipped with a backrest and a lumbar support, and the armrests are installed on the chair armrests. The armrests of the chair are usually fixed to the chair by a bracket. The armrests are mainly for people to place their arms for comfort.

[0003] At present, most of the existing chair armrests are installed by bolts or integrally formed, so that the armrests can be installed on the oval pipe of the chair. However, during the installation of the armrests, due to their simple structure, they are often directly inserted into the oval pipe of the chair or fixed with bolts. During the whole fixing process, due to the soft texture of the chair armrests themselves, position deviation is easy to occur during the process of screwing the screws, which affects the actual installation of the entire chair armrest, and is not convenient for installation and use. In view of this, we introduce a snap-on chair armrest. Summary of the invention

[0004] The purpose of the utility model is to provide a snap-on chair armrest to solve the problems raised in the above-mentioned background technology.

[0007] The buckle B is arranged on the inner side of the armrest, and the buckle B and the armrest are integrally formed. A positioning column is arranged on the inner bottom wall of the armrest, and the positioning column and the armrest are integrally formed.

[0008] Preferably, a fixing mechanism is provided inside the armrest, and the moving plate and the plug-in rod are driven to move by a spring of the fixing mechanism, so that the plug-in rod is inserted into the interior of the chair to be fixed.

[0009] The fixing mechanism includes a positioning cavity opened inside the armrest, and the positioning cavity and the armrest are integrally formed. The movable plate is slidably connected to the inside of the positioning cavity, and the upper and lower ends of the movable plate are respectively in contact with the inner wall of the positioning cavity, so that the movement of the movable plate is limited by the inner wall of the positioning cavity, and the movement is always in a horizontal state. The plug-in rod is connected to one side of the movable plate, and the plug-in rod and the movable plate are fixed, and the plug-in rod passes through the armrest. A pull rod is connected to the other side of the movable plate, and the spring is sleeved on the surface of the pull rod.

[0010] Preferably, one end of the pull rod passes through the handrail and is connected to a pull plate, and the pull plate and the pull rod are welded.

[0011] Preferably, one end of the armrest is connected to an inclined portion, and the inclined portion and the armrest are integrally formed, and the inclined portion is convenient for placing the user's hand.

[0012] Compared with the prior art, the beneficial effect of the utility model is as follows: the utility model inserts the armrest into the oval tube on the chair, and the positioning column on the inner side of the armrest is inserted into the inside of the oval tube on the chair, and the buckle A and the buckle B are used together to fix the surface of the oval tube on the chair, and then the pulling of the pulling plate is released, and the elastic force of the spring itself is used to move the movable plate, the connecting rod, the pulling rod and the movable plate to the initial position, so that the connecting rod is moved to the inside of the oval tube on the chair, thereby further fixing the armrest, making it more firmly fixed, thereby avoiding the use of bolts to fix the armrest.

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-5 The utility model provides a technical solution: a buckle-type chair armrest, comprising: an armrest 1, a buckle A3 is arranged on the inner side of the armrest 1, and a curved portion 4 is connected to the surface of the buckle A3;

[0021] Buckle B13, the buckle B13 is arranged on the inner side of the handrail 1, and a positioning column 2 is arranged on the inner bottom wall of the handrail 1;

[0022] A fixing mechanism is provided inside the armrest 1 , and the spring 12 of the fixing mechanism drives the moving plate 9 and the plug-in rod 5 to move, so that the plug-in rod 5 is inserted into the interior of the chair to be fixed.

[0023] The fixing mechanism includes a positioning cavity 11 opened inside the armrest 1, and the positioning cavity 11 and the armrest 1 are integrally formed. The movable plate 9 is slidably connected to the inside of the positioning cavity 11, and the upper and lower ends of the movable plate 9 are respectively in contact with the inner wall of the positioning cavity 11, so that the movement of the movable plate 9 is limited by the inner wall of the positioning cavity 11, and the movement is always in a horizontal state. The plug-in rod 5 is connected to one side of the movable plate 9, and the plug-in rod 5 and the movable plate 9 are fixedly set, and the plug-in rod 5 passes through the armrest 1. The other side of the movable plate 9 is connected to the pull rod 8, and the spring 12 is sleeved on the surface of the pull rod 8.

[0024] One end of the pull rod 8 passes through the handrail 1 and is connected to a pull plate 7 , and the pull plate 7 and the pull rod 8 are welded.

[0025] One end of the armrest 1 is connected to an inclined portion 6, and the inclined portion 6 and the armrest 1 are integrally formed. The inclined portion 6 is convenient for the user to place his / her hand there.

[0026] Specifically, when in use, first pull the pull plate 7, so that the pull plate 7 drives the pull rod 8, the movable plate 9 and the plug rod 5 to move, so that the movable plate 9 can move inside the positioning cavity 11, and the movable plate 9 can be used to squeeze the spring 12 on the surface of the pull rod 8 to compress the spring 12. Since the upper and lower ends of the movable plate 9 are respectively in contact with the positioning cavity 11, the movement of the movable plate 9 can always be in a horizontal state. At this time, the movable plate 9 can drive the plug rod 5 to move to the inside of the positioning cavity 11, and then the armrest 1 is inserted into the oval tube on the chair. At this time, the inner side of the armrest 1 The positioning column 2 will be inserted into the inside of the oval tube on the chair. At this time, the buckle A3 and the buckle B13 are used together to fix the buckle A3 and the buckle B13 to the surface of the oval tube on the chair, and then the pulling of the pulling plate 7 is released. At this time, the elastic force of the spring 12 itself is used to move the moving plate 9, the connecting rod 5, the pulling rod 8 and the moving plate 9 to the initial position, so that the connecting rod 5 is moved to the inside of the oval tube on the chair, thereby further fixing the armrest 1, making it more firmly fixed, thereby avoiding the use of bolts to fix the armrest 1.
