Seat connecting structure of plane stand

Abstract

The utility model provides a plane stand seat connecting structure. The plane stand seat connecting structure comprises two supports and at least three sets of seat rows installed on the two supports. Each support comprises a supporting plate and at least three rectangular pipes arranged on the supporting plate at equal intervals. Each seat row comprises a cross rod and at least four seats arranged on the cross rod at equal intervals. Rectangular pipe legs are arranged at the two ends of the transverse rod and installed in the rectangular pipes. According to the utility model, a plurality of seats are arranged on one cross rod to form a whole, so that the situation that a single seat is easy to become an attack tool once a large-scale activity auditorium is disturbed is avoided. Meanwhile, a plurality of groups of seat rows are mounted on the two brackets to form a matrix, so that the condition that a single seat is easily scattered back and forth by audiences is effectively avoided. And the problems of fire-fighting potential safety hazards and auditorium public security in large-scale activities are avoided.

Description

Technical Field

[0001] The utility model relates to the technical field of seats, in particular to a connecting structure for flat grandstand seats. Background Art

[0002] When holding large-scale events, such as concerts, variety shows, and sports events, in the area relatively close to the performance stage (the so-called inner field in a concert), there are often no step-by-step platforms as the grandstand foundation. At this time, in order to make good use of the inner field space with good viewing distance, it is often necessary to place some temporary chairs. The advantages of these temporary chairs are that they are convenient to collect and place, and the chairs can be stacked, which is beneficial for placing on a vehicle for transportation. At the same time, due to their small size and light weight, they are convenient for quick arrangement in the venue.

[0003] However, the disadvantages of these temporary chairs are as follows: 1. They are easily scattered by the back-and-forth movement of the audience, disrupting the original seat matrix formation and posing a fire safety hazard for large-scale events; 2. Once there is a commotion in the grandstand of a large-scale event, individual seats are likely to become tools for attack. Content of the Utility Model

[0004] The purpose of the utility model is to provide a connecting structure for flat grandstand seats, which can solve the problem that the existing chairs temporarily arranged for large-scale events are easily picked up or impacted and moved.

[0005] The purpose of the utility model is achieved through the following technical solutions:

[0006] A connecting structure for flat grandstand seats includes two brackets and at least three groups of seat rows installed on the two brackets. Each bracket includes a support plate and at least three rectangular tubes arranged equidistantly on the support plate. Each group of seat rows includes a cross bar and at least four seats arranged equidistantly on the cross bar. Rectangular tube legs are provided at both ends of the cross bar, and the rectangular tube legs are installed in the rectangular tubes.

[0007] Preferably, the rectangular tube legs and the rectangular tubes are fixed to each other by means of pins.

[0008] Preferably, the rectangular tubes are fixed to the support plate by welding.

[0009] Preferably, the support plate is a U-shaped steel plate.

[0010] Preferably, fixing parts for installation on the cross bar are provided on both sides of the seats.

[0011] Preferably, the rectangular tube legs are welded to both ends of the cross bar; the fixing parts are fixed to the cross bar by welding or bolts.

[0012] Preferably, the number of rectangular tubes on each bracket is the same as the number of seat rows.

[0013] The utility model forms an integral body by installing multiple seats on a cross bar, avoiding the situation that in a large-scale event, once there is a commotion in the auditorium, a single seat is likely to become a tool for attack. At the same time, multiple rows of seats are installed on two brackets to form a matrix formation, effectively avoiding the situation that a single seat is easily scattered back and forth by the audience. It avoids the potential fire safety hazards and security problems in the auditorium during large-scale events. BRIEF DESCRIPTION OF THE DRAWINGS

Embodiment 1

[0020] The utility model forms an integral body by installing multiple seats 22 on a cross bar 21, avoiding the situation that in a large-scale event, once there is a commotion in the auditorium, a single seat 22 is likely to become a tool for attack. At the same time, multiple rows of seats 2 are installed on two brackets 1 to form a matrix formation, effectively avoiding the situation that a single seat 22 is easily scattered back and forth by the audience. It avoids the potential fire safety hazards and security problems in the auditorium during large-scale events.

[0021] As Figure 1-2As shown in the figure, a connecting structure for plane grandstand seats includes two brackets 1 and at least three groups of seat rows 2 installed on the two brackets 1. Each bracket 1 includes a support plate 11 and at least three rectangular tubes 12 arranged equidistantly on the support plate 11. Each group of seat rows 2 includes a cross bar 21 and at least four seats 22 arranged equidistantly on the cross bar 21. Rectangular tube legs 23 are provided at both ends of the cross bar 21, and the rectangular tube legs 23 are installed inside the rectangular tubes 12.
