Description

Background Art

[0001] The utility model relates to a fixed fire extinguishing system for a bus passenger cabin, belonging to the field of fire fighting equipment, in particular to a fire extinguisher bottle group. Technical Field

[0002] The applicant has designed a fire extinguishing system for small and medium-sized buses such as airport minibuses, intercity minibuses, and township buses, among which a fire extinguisher bottle group composed of multiple fire extinguisher bottles is used. The reliability of the fixing frame used to fix multiple fire extinguisher bottles has a fatal impact on the entire fire extinguishing system. Since the bus is moving, and the probability of causing violent vibrations due to emergency braking during the walking process is difficult to eliminate, in this state, if the reliability of the connection of the bottle body fixing frame in the fire extinguisher bottle group is poor, the connection fixing frame will be loose, resulting in the breakage or detachment of the connecting pipe fittings, and the consequences are unimaginable. The existing fixing frame is realized by using a steel belt and a tightening screw solution. Vertical tightening folds are set at both ends of the steel belt, and connecting holes are set on the folds. The steel belt is adjusted by tightening screws to achieve the purpose of tightening and fixing the bottle group. However, in actual use, the edges at both ends of the steel belt are deformed when the screws are tightened. It is difficult to control how to meet the tightening requirements here. In the process of vehicle driving, sudden working conditions such as braking that cause violent vibrations are inevitably generated. In order to improve the reliability of the fixation of the fire extinguisher bottle group, the applicant designed a vibration-resistant and loose-proof fire extinguisher bottle group fixing bracket. Utility Model Content

[0003] The utility model aims to provide a fire extinguisher bottle group fixing frame which is anti-tightening and deformation-proof, and which can keep all the bottles fixed under the working condition of continuous vibration, and will not have false tightening when tightening, and the folded edges at both ends of the steel belt will not be deformed and straightened due to the increase of the tightening force, and will not loosen under the working condition of vibration.

[0004] The technical solution adopted by the utility model is as follows: a fire extinguisher bottle group fixing frame that prevents tightening and deformation, characterized in that: it includes a central connecting shaft, a tightening hoop group, a bottom fixing plate and a reinforced fixing plate, two or more tightening hoop groups for fixing the fire extinguishing agent bottle body are arranged at intervals on the central connecting shaft, each tightening hoop group includes three or more tightening hoops evenly distributed along the circumferential direction, a bending edge is provided at the opening of each tightening hoop, a through hole is provided at the center position of the bending edge, triangular support plates are provided on both sides of the bending edge 22, the bottom fixing plate is fixed between two adjacent tightening hoops, one end of the reinforced fixing plate is fixedly connected to the bottom fixing plate, the other end of the reinforced fixing plate is fixedly connected to the central connecting shaft, the reinforced fixing plate is in the tangent plane of the two adjacent tightening hoops, all tightening hoops are fixed on the central connecting shaft, and the fire extinguishing agent bottle body is fixed by the corresponding tightening hoops in each tightening hoop group that are on the same axis.

[0005] Furthermore, two tightening hoop groups for fixing the fire extinguisher bottle body are arranged at intervals on the central connecting shaft, and each tightening hoop group includes three tightening hoops evenly distributed along the circumference and a bottom fixing plate, and a bottom fixing plate is fixed between two adjacent tightening hoops.

[0006] Since the fire extinguishing agent bottle is circumferentially fixed by more than two coaxial tightening hoops, a bent edge is provided at the opening of each tightening hoop, a through hole is provided at the center position of the bent edge, and triangular support plates are provided on both sides of the bent edge. In this way, when the screw is tightened, the spacing between the two end openings of the tightening hoop gradually decreases, that is, the inner diameter of the tightening hoop is reduced, thereby tightening and fixing the fire extinguishing agent bottle. In this process, since bent edges are respectively provided at both ends of the steel belt of the tightening hoop, the bent edges at both ends of the steel belt of the tightening hoop are butt-jointed to form an adjustment opening, and triangular support plates are fixed on both sides of the bent edge. In this way, when the tightening screw sleeved in the center through hole of the bent edge is tightened, the extension deformation of the combination of the bent edge and the triangular support plates on both sides thereof under the tension state is extremely small. Therefore, even if there are frequent rapid braking and other working conditions that are prone to produce rapid vibration during the driving of the vehicle, the tightening hoop will not loosen, thereby improving the stability and reliability of the fixation of the fire extinguishing agent bottle.

[0007] The bottom fixing plate is fixed between two adjacent tightening hoops, so that the entire fire extinguisher bottle group can be conveniently and reliably installed on the car floor. One end of the reinforced fixing plate is fixedly connected to the bottom fixing plate, and the other end of the reinforced fixing plate is fixedly connected to the central connecting shaft. The reinforced fixing plate is located in the tangent plane of the two adjacent tightening hoops, and all the tightening hoops are fixed on the central connecting shaft. Such a structure enhances the connection strength and rigidity of the entire fixing frame, and ideally overcomes the shortcomings of the prior art. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The present invention will be further described below in conjunction with the accompanying drawings and specific examples.

[0016] Implementation Example 1: A fire extinguisher bottle assembly fixing frame that prevents tightening and deformation, such as Figure 1-6 As shown, it includes a central connecting shaft 1, a tightening hoop group 2, a bottom fixing plate 3 and a reinforced fixing plate 4. Two tightening hoop groups 2 for fixing the fire extinguishing agent bottle 5 are arranged at intervals on the central connecting shaft 1. Each tightening hoop group 2 includes three tightening hoops 21 uniformly distributed along the circumferential direction. A bending edge 22 is provided at the opening of each tightening hoop 21. A through hole 23 is provided at the center position of the bending edge 22. Triangular support plates 24 are provided on both sides of the bending edge 22. The bottom fixing plate 3 is fixed between two adjacent tightening hoops 21. One end of the reinforced fixing plate 4 is fixedly connected to the bottom fixing plate 3, and the other end of the reinforced fixing plate 4 is fixedly connected to the central connecting shaft 1. The reinforced fixing plate 4 is in the tangent plane of the two adjacent tightening hoops 21. All tightening hoops 21 are fixed on the central connecting shaft 1, and the fire extinguishing agent bottle 5 is fixed by the corresponding tightening hoop 21 in the corresponding tightening hoop group 2 that is on the same axis.

[0017] Since each fire extinguishing agent bottle 5 is circumferentially fixed by two coaxial tightening hoops 21, a bent edge 22 is provided at the opening of each tightening hoop 21, a through hole 23 is provided at the center of the bent edge 22, and triangular support plates 24 are provided on both sides of the bent edge 22. In this way, when the screw 6 is tightened, the distance between the openings at both ends of the tightening hoop 21 is gradually reduced, that is, the inner diameter of the tightening hoop 21 is reduced, so that the fire extinguishing agent bottle 5 is tightened and fixed. In this process, since the steel belts of the tightening hoop 21 are respectively provided at both ends, There is a bending edge 22, and triangular support plates 24 are fixed on both sides of the bending edge 22. In this way, when the tightening screw 6 set in the central through hole 23 of the bending edge 22 is tightened, the combination of the bending edge 22 and the triangular support plates 24 on both sides thereof is tightened and narrowed through the bending edges 22 at both ends of the steel belt of the tightening hoop 21. The deformation of the combination of the bending edge 22 and the triangular support plates 24 on both sides thereof under tension is extremely small, that is, the fixing loosening of the fire extinguishing agent bottle 5 will not be caused by the extension deformation of the bending edge. Even if there are frequent rapid braking and other working conditions that are prone to sudden vibration during the driving of the vehicle, the tightening hoop 21 will not be extended and loosened due to the bending edge 22 under the tension state, thereby improving the stability and reliability of the fixing of the fire extinguishing agent bottle 5.

[0018] The bottom fixing plate 3 is fixed between two adjacent tightening hoops 21, so that the entire fire extinguisher bottle group can be conveniently and reliably installed on the car floor. One end of the reinforced fixing plate 4 is fixedly connected to the bottom fixing plate 3, and the other end of the reinforced fixing plate 4 is fixedly connected to the central connecting shaft 1. The reinforced fixing plate 4 is in the tangent plane of the two adjacent tightening hoops 21, and all the tightening hoops 21 are fixed on the central connecting shaft 1. Such a structure enhances the connection strength and rigidity of the entire fixing frame, and ideally overcomes the shortcomings of the prior art.
