Description

Technical Field

[0001] This utility model belongs to the field of seating technology, specifically relating to an auditorium chair. Background Technology

[0002] Auditorium chairs are fixed seats designed specifically for public spaces such as auditoriums, theaters, and meeting halls. They are made of steel and wood, steel-plastic, or aluminum and wood. The core components include the seat, backrest, armrests, legs, and a retractable writing board. Some models are equipped with local lighting, cup holders, and other simultaneous interpretation equipment to meet multi-functional needs.

[0003] The writing pads on the auditorium chairs are usually flipped out for use. After use, they need to be flipped back and manually pushed back into the storage compartment. This method of operation can easily lead to the writing pads being forgotten to be pushed back, affecting subsequent use. Utility Model Content

[0004] The purpose of this utility model is to provide an auditorium chair that is easy to use and facilitates the protection of the tabletop structure, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an auditorium chair, comprising a seat body and mounting bases, wherein there are two mounting bases, which are respectively fixedly connected to both sides of the seat body. One end of one of the mounting bases is provided with a placement groove, and a slider is slidably connected inside the placement groove. One end of the slider is provided with a tabletop structure, and springs are symmetrically arranged at one end of the slider. One end of the springs is fixedly connected to one end of the placement groove.

[0006] Furthermore, dovetail grooves are provided on both sides of the slider, and trapezoidal slide bars are fixedly connected to both sides of the inner wall of the mounting groove. The two trapezoidal slide bars are slidably connected to the two dovetail grooves respectively.

[0007] Furthermore, one end of the slider is symmetrically provided with mounting holes, and one end of the spring is fixedly connected to the inside of the mounting holes.

[0008] Furthermore, the tabletop structure includes a connecting shaft, one end of which is rotatably connected to the top of one end of the slider, and a cylinder is fixedly connected to one end of the side wall of the connecting shaft, with the tabletop fixedly connected to the side wall of the cylinder.

[0009] Furthermore, a limiting seat is fixedly connected to the side wall of the connecting shaft, and a support seat that cooperates with the limiting seat is fixedly connected to one end of the dovetail groove.

[0010] Compared with the prior art, the beneficial effects of this utility model are: when the tabletop structure is not in use, the tabletop structure can be reversed, and under the pull of the spring, the slider will drive the tabletop structure to automatically retract into the inside of the mounting groove, thereby preventing the tabletop structure from being exposed to the outside. It is convenient to use and easy to protect the tabletop structure. Attached Figure Description

[0012] The attached diagram lists the components represented by each number as follows: 1. Seat body; 2. Mounting base; 3. Mounting groove; 31. Trapezoidal slide bar; 4. Slider; 41. Dovetail groove; 42. Mounting hole; 5. Table structure; 51. Connecting shaft; 52. Limiting seat; 53. Support seat; 54. Cylinder; 55. Table; 6. Spring. Detailed Implementation

[0013] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0014] like Figure 1-3 As shown, an auditorium chair includes a seat body 1 and a mounting base 2. There are two mounting bases 2, which are fixedly connected to the two sides of the seat body 1 respectively. One end of one mounting base 2 is provided with a placement groove 3. A slider 4 is slidably connected inside the placement groove 3. A table board structure 5 is provided at one end of the slider 4. A spring 6 is symmetrically provided at one end of the slider 4. One end of the spring 6 is fixedly connected to one end of the placement groove 3.

[0015] According to the above structure, when the tabletop structure 5 is not in use, it can be reversed. Under the pull of the spring 6, the slider 4 will cause the tabletop structure 5 to automatically retract into the placement groove 3, thereby preventing the tabletop structure 5 from being exposed to the outside. This makes it convenient to use and easy to protect the tabletop structure 5.

[0016] like Figure 2-4As shown, dovetail grooves 41 are provided on both sides of the slider 4, and trapezoidal slide bars 31 are fixedly connected to both sides of the inner wall of the mounting groove 3. The two trapezoidal slide bars 31 are slidably connected to the two dovetail grooves 41 respectively. One end of the slider 4 is symmetrically provided with mounting holes 42, and one end of the spring 6 is fixedly connected to the inside of the mounting holes 42.

[0017] According to the above structure, when in use, by pulling the table structure 5 outward, the slider 4 is moved outward, thereby stretching the spring 6. When the slider 4 moves, the dovetail groove 41 slides along the trapezoidal slide bar 31, improving the stability of the slider 4 inside the mounting groove 3.

[0018] like Figure 4 As shown, the table structure 5 includes a connecting shaft 51, one end of which is rotatably connected to the top of one end of the slider 4. A cylinder 54 is fixedly connected to one end of the side wall of the connecting shaft 51, and a table 55 is fixedly connected to the side wall of the cylinder 54. A limiting seat 52 is fixedly connected to the side wall of the connecting shaft 51, and a support seat 53 that cooperates with the limiting seat 52 is fixedly connected to one end of the dovetail groove 41.

[0019] According to the above structure, when the table structure 5 is pulled out, the table 55 is rotated upward so that the limiting seat 52 contacts the support seat 53, thereby restricting the position of the table 55. The table 55 is blocked by one end of the mounting seat 2 to prevent it from retracting for use. After use, the table 55 is rotated in the opposite direction, which can cause the spring 6 to pull the slider 4 inward, thereby causing the slider 4 and the table structure 5 to retract together into the interior of the mounting groove 3.

[0020] The working principle of this utility model is as follows: When the table structure 5 is not in use, it is reversed. Under the pull of the spring 6, the slider 4 drives the table structure 5 to automatically retract into the interior of the mounting groove 3, thereby preventing the table structure 5 from being exposed to the outside. This is convenient to use and also facilitates the protection of the table structure 5. When in use, by pulling the table structure 5 outward, the slider 4 is moved outward, thereby stretching the spring 6. When the slider 4 moves, the dovetail groove 41 slides along the trapezoidal slide bar 31, improving the stability of the slider 4 inside the mounting groove 3. After the table structure 5 is pulled out, the table 55 is rotated upward, so that the limiting seat 52 contacts the support seat 53, thereby restricting the position of the table 55. The table 55 is blocked by one end of the mounting seat 2 to prevent it from retracting for use. After use, the table 55 is rotated in the opposite direction, which allows the spring 6 to pull the slider 4 inward, thereby causing the slider 4 and the table structure 5 to retract together into the interior of the mounting groove 3.

[0021] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
