Description

Technical Field

[0001] This utility model belongs to the field of office furniture technology, specifically relating to a single-axis supported auditorium chair. Background Technology

[0002] Single-axis supported auditorium seating is a public seating system that uses a single vertical axis as its main load-bearing structure. This axis is typically made of metal (such as steel or aluminum alloy), runs through the seat base, and is firmly connected to the ground to form a stable support structure. Its design emphasizes a combination of simplicity, modularity, and functionality, making it suitable for high-density gathering places such as conference halls and auditoriums.

[0003] The current single-axis auditorium seating requires strict adherence to a straight horizontal / vertical alignment during installation; otherwise, it will appear visually cluttered and affect passage and user experience. However, measurement errors or uneven ground often lead to skewing, affecting the neatness of the seating array. Furthermore, the seating is only fixed by independent anchor bolts, lacking lateral restraint, which can easily result in wavy misalignment after long-term use. This independent anchoring can also easily cause localized stress concentration, which can easily lead to loosening, abnormal noise, or even structural damage under frequent opening and closing or crowding. Utility Model Content

[0004] The purpose of this invention is to provide a single-axis supported auditorium seat. By constructing physical constraints through connecting rods that run through adjacent seats, it eliminates the tilting phenomenon caused by measurement errors or uneven ground in traditional installation, making the seat array more orderly. It can also transform the individual seats into a rigid integral structure, sharing the pressure and load together, thereby reducing the risk of individual seats tipping over and significantly improving impact resistance.

[0005] The specific technical solution adopted by this utility model is as follows: A single-axis supported auditorium seat includes a support shaft fixedly disposed under the seat. A limiting plate is fixedly connected to the side wall of the support shaft. Wing plates are symmetrically provided at both ends of the limiting plate. A connecting rod is provided between the support shafts of two adjacent seats. The connecting rod passes through the corresponding wing plates through threaded sections at both ends, and is screwed to the threaded sections on both sides of the wing plates by nuts.

[0006] The length of the connecting rod is less than the axial distance between the two support shafts and greater than the linear distance between the two wing plates.

[0007] The two threaded segments rotate in opposite directions.

[0008] Dust covers are rotatably hinged to both the upper and lower sides of the wing plate, and the dust covers are placed on the outside of the threaded section to form a material barrier.

[0009] The axial length of the dust cover is greater than the sum of the splicing lengths of the two threaded segments.

[0010] One of the dust covers has a convex ball fixedly connected to its side wall, and the other dust cover has a corresponding symmetrical elastic clamping plate on its side wall.

[0011] The inner diameter formed by the two elastic clamping plates is smaller than the outer diameter of the convex ball.

[0012] The technical effects achieved by this utility model are as follows: by constructing physical constraints through the connecting rods that run through adjacent seats, the skewing phenomenon caused by measurement errors or uneven ground in traditional installation is eliminated, making the seat array more neat; it can also transform each independent seat into a rigid integral structure, sharing the pressure and load together, thereby reducing the risk of tipping over of individual seats and greatly improving impact resistance.

[0015] 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.

[0016] like Figures 1-5As shown, a single-axis supported auditorium seat includes a support shaft 1 fixedly mounted under the seat. A limiting plate 2 is fixedly connected to the side wall of the support shaft 1. Wing plates 201 are symmetrically provided at both ends of the limiting plate 2. A connecting rod 202 is provided between the support shafts 1 of two adjacent seats. The connecting rod 202 passes through the corresponding wing plates 201 through threaded sections 203 at both ends, and is screwed to the threaded sections 203 on both sides of the wing plate 201 by nuts 204. The length of the connecting rod 202 is less than the axial distance between the two support shafts 1 and greater than the axial distance between the two wing plates 201. The straight-line spacing of the plate 201, the opposite rotation directions of the two threaded sections 203, and the dust cover 205 is rotatably hinged on both the upper and lower sides of the wing plate 201. The dust cover 205 covers the outside of the threaded section 203 to form a material barrier. The axial length of the dust cover 205 is greater than the sum of the splicing lengths of the two threaded sections 203. A convex ball 206 is fixedly connected to the side wall of one of the dust covers 205, and an elastic clamping plate 207 is symmetrically provided on the side wall of the other dust cover 205. The inner diameter formed by the two elastic clamping plates 207 is smaller than the outer diameter of the convex ball 206.

[0017] According to the above structure, first screw the nuts 204 to the threaded sections 203 at both ends of the connecting rod 202 respectively. When the two seats are placed side by side, insert the threaded section 203 at one end of the connecting rod 202 into one of the wing plates 201 of the left seat, and then insert the threaded section 203 at the other end into the wing plate 201 of the right seat. Finally, screw the two nuts 204 to the ends of the threaded sections 203 respectively, and adjust the screwing until the two nuts 204 on both sides of the wing plate 201 are in contact with and clamped, thereby forcing the two support shafts 1 to align. At this time, the end of the threaded section 203 does not exceed the central axis of the limiting plate 2, so that the other wing plate 201 of the limiting plate 2 can be inserted and fixed with the corresponding threaded section 203. Furthermore, the two dust covers 205 are rotated simultaneously to lock together, covering the threaded section 203 to prevent dust. The elastic clamping plate 207 is made of elastic material. When the convex ball 206 is engaged with the elastic clamping plate 207, the two elastic clamping plates 207 are squeezed and elastically displaced to both sides. After the convex ball 206 is fully engaged, the elastic clamping plate 207 springs back and resets to one side of the convex ball 206, limiting the convex ball 206 to prevent the dust cover 205 from opening and closing arbitrarily.

[0018] The working principle of this utility model is as follows: First, the nut 204 is initially screwed into the threaded sections 203 at both ends of the connecting rod 202; when the two seats are arranged side by side, the threaded section 203 at one end of the connecting rod 202 is precisely inserted into the wing plate 201 of the left seat, and then the threaded section 203 at the other end is correspondingly inserted into the wing plate 201 of the right seat. Furthermore, nuts 204 are screwed into the ends of each threaded section 203 one by one and finely adjusted until the nuts 204 on both sides of the wing plate 201 are tightly fitted and securely clamped, thereby forcing the two support shafts 1 to be precisely aligned. In this state, the ends of the threaded sections 203 are controlled within the central axis of the limiting plate 2 so that the wing plate 201 on the other side of the limiting plate 2 can be smoothly inserted and fixed with the corresponding threaded section 203. Furthermore, the two dust covers 205 are rotated to make them interlock and fully cover the threaded section 203 to achieve the purpose of dust prevention. The elastic clamping plate 207 can be made of elastic materials such as EPDM rubber, thermoplastic polyurethane, and nylon, but EPDM rubber is preferred to balance clamping force and elasticity. Furthermore, when the convex ball 206 is embedded in the elastic clamping plate 207, the two elastic clamping plates 207 will undergo elastic deformation to both sides under the squeezing action; after the convex ball 206 is fully embedded, the elastic clamping plate 207 quickly rebounds and returns to one side of the convex ball 206, forming an effective limit on the convex ball 206, thereby effectively preventing the dust cover 205 from being opened accidentally. Furthermore, the two support shafts 1 are connected by the connecting rod 202, and the remaining seats can be connected in sequence in the same way, thereby standardizing and restricting the neatness of the splicing of multiple seats and making them form a rigid whole.

[0019] 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.
