Detailed Implementation

[0022] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0023] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0024] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0025] For an example, please refer to... Figures 1-4 A multi-directional snap-fit ​​auditorium chair armrest includes a mounting base 1, a support shaft 2 fixedly connected to the mounting base 1, a protective shell 201 sleeved on the outer surface of the support shaft 2 via bearings, an armrest body 202 fixedly connected to the protective shell 201, and a locking structure between the armrest body 202 and the support shaft 2. The locking structure is used to limit the adjustment of the armrest body 202. The locking structure includes a fixing plate 3 fixedly installed on the outer surface of the support shaft 2 and located inside the protective shell 201. Several openings are formed on the outer periphery of the fixing plate 3. Each armrest body 202 has a limiting hole 301 and a limiting rod 305 is provided inside the armrest body 202. One end of the limiting rod 305 is inserted into one of the limiting holes 301. In this application, the armrest body 202 and the protective shell 201 can rotate around the support shaft 2 at multiple angles, that is, multi-directional adjustment is achieved. After adjustment, the armrest body 202 is fixed by the locking of the limiting rod 305 and the limiting hole 301, so that the armrest body 202 can be adjusted according to different usage scenarios and user needs, thereby improving the applicability and comfort of the auditorium chair.

[0026] It should be noted that the armrest body 202 in this application is capable of multi-angle adjustment, rather than stepless adjustment of all angles.

[0027] Furthermore, a second support plate 304 and a first support plate 303 are sleeved on the outer surface of the limiting rod 305. The second support plate 304 and the first support plate 303 are both fixedly installed inside the handrail body 202, and the first support plate 303 is located between the fixed plate 3 and the second support plate 304. The first support plate 303 and the second support plate 304 cooperate with each other to support the limiting rod 305.

[0028] Furthermore, a baffle 306 is fixedly sleeved on the outer surface of the limiting rod 305. The baffle 306 is located between the second support plate 304 and the first support plate 303, and one side of the baffle 306 is in contact with the first support plate 303. A first spring 307 is sleeved on the outer surface of the limiting rod 305. The first spring 307 is located between the baffle 306 and the second support plate 304, and both ends of the first spring 307 are in contact with the second support plate 304 and the baffle 306, respectively. The force of the first spring 307 can limit the limiting rod 305 through the baffle 306, so as to improve the stability of the limiting rod 305 when it is inserted into the limiting hole 301.

[0029] Furthermore, the opening of the limiting hole 301 is chamfered, and the end of the limiting rod 305 near the fixed plate 3 is also chamfered. The chamfering facilitates the insertion of the limiting rod 305 into the limiting hole 301.

[0030] Furthermore, a number of limiting holes 301 are distributed in a circle on the fixed plate 3 with the support shaft 2 as the center, and the spacing between the limiting holes 301 is the same, so that the limiting holes 301 are evenly distributed.

[0031] Furthermore, a T-shaped rod 313 is fixedly installed inside the handrail body 202. A connecting tube 310 is sleeved on the outer surface of the T-shaped rod 313. A connecting rope 308 is connected between the connecting tube 310 and the limiting rod 305. A guide wheel 309 that is slidably connected to the connecting rope 308 is also provided inside the handrail body 202. The T-shaped rod 313 can support the connecting tube 310. When the connecting tube 310 moves towards the fixed plate 3, the limiting rod 305 is pulled by the connecting rope 308 and the guide wheel 309 so that the limiting rod 305 is separated from the limiting hole 301. The connecting rope 308 can be made of carbon fiber rope.

[0032] Furthermore, a button 311 is fixedly connected to one end of the connecting tube 310 away from the T-shaped rod 313. One end of the button 311 extends out of the armrest body 202 and to the outside of the armrest body 202. The button 311 is designed to be pressed to unlock when the user adjusts the armrest.

[0033] Furthermore, a second spring 314 is sleeved on the outer surface of the T-shaped rod 313. The force of the second spring 314 can drive the button 311 to extend and reset when the user releases the button 311.

[0034] Furthermore, the mounting base 1 has several mounting holes 101 for fixing to the auditorium chair with screws.

[0035] The multi-directional interlocking auditorium chair armrest provided by this utility model is used as follows:

[0036] During adjustment, press button 311. Button 311 pushes connecting tube 310 towards fixed plate 3. Connecting tube 310, through connecting rope 308, drives limiting rod 305 away from fixed plate 3, thereby separating limiting rod 305 from limiting hole 301 for unlocking. At this time, rotating handrail body 202 around support shaft 2 can adjust the angle of support shaft 2. After adjustment, release button 311. The force of second spring 314 drives button 311 to reset and extend through connecting tube 310. If limiting rod 305 is aligned with limiting hole 301, limiting rod 305 is directly inserted into limiting hole 301 under the action of first spring 307 and baffle 306. If limiting rod 305 is not aligned with limiting hole 301, limiting rod 305 contacts fixed plate 3 under the action of first spring 307 and baffle 306. Slightly rotate handrail body 202. When limiting rod 305 is aligned with limiting hole 301, it can be inserted.
