Fire hose connection bracket

Abstract

This application relates to the field of connecting bracket technology and discloses a fire-fighting pipe connecting bracket, including two support arms. The middle of the two support arms is connected to a connecting column. A linkage shaft is installed on the connecting column, and two connecting rods are hinged to the linkage shaft. The ends of the two connecting rods away from the linkage shaft are respectively hinged to the left clamping arm and the right clamping arm.

Description

Technical Field

[0001] This application relates to the field of connecting bracket technology, and in particular to a fire-fighting pipe connecting bracket. Background Technology

[0002] As a core component of a building's fire protection system, the stability of fire-fighting pipelines is directly related to the reliability of fire-fighting water supply during a fire. Therefore, pipeline connection brackets, as key components for pipeline installation, must meet requirements such as secure clamping, strong adaptability, convenient installation, and durable structure.

[0003] However, the fire protection pipe connection brackets currently on the market still have many problems that urgently need to be solved: First, the clamping structure of existing connection brackets is mostly fixed or has a limited adjustment range, making it difficult to adapt to fire protection pipes of different diameters. Moreover, the clamping is mostly point contact or line contact, resulting in uneven distribution of clamping force. This makes the pipes prone to axial sliding, circumferential rotation, or even loosening and falling off after installation due to vibration, external impact, or long-term load, seriously affecting the safety of the fire protection system. Second, the support structure angle of most connection brackets is fixed, and it is impossible to flexibly adjust it according to the installation environment (such as wall spacing, installation height, and pipe routing). This results in poor adaptability, increases installation difficulty and construction costs, and makes it difficult to achieve stable support, especially in complex building spaces. Third, the structural design of some connection brackets in key stress-bearing parts (such as the connection of the clamping arm and the connection between the support arm and the connecting column) is weak and lacks effective reinforcement measures. When subjected to the weight of the pipe or external forces for a long time, they are prone to deformation and cracking, leading to clamping failure. Utility Model Content

[0004] The fire-fighting pipe connection bracket provided in this application adopts the following technical solution:

[0005] A fire-fighting pipe connection bracket includes two support arms, the middle of which is connected to a connecting column. A linkage shaft is installed on the connecting column, and two connecting rods are hinged on the linkage shaft. The ends of the two connecting rods away from the linkage shaft are respectively hinged to a left clamping arm and a right clamping arm. The left clamping arm and the right clamping arm are symmetrically arranged and cooperate to form a fire-fighting pipe clamping space.

[0006] Preferably, the lower part of the connecting column extends into an adjusting column, and the lower end of the adjusting column is provided with a linkage joint, which is respectively hinged to the left clamping arm and the right clamping arm.

[0007] Preferably, the connecting column has a positioning hole, and a fixing bolt passes through the positioning hole. The fixing bolt is used to lock the relative position of the support arm and the connecting column.

[0008] Preferably, the left clamping arm includes a connecting arm, a clamping arm body, and a clamping plate. One end of the connecting arm is hinged to a connecting rod, and the other end is fixedly connected to the clamping arm body. The clamping plate is disposed at the end of the clamping arm body facing the clamping space.

[0009] Preferably, the clamping arm body has a hinge hole, which is adapted to be hinged with the linkage joint of the adjusting column.

[0010] Preferably, the edge of the clamping plate is provided with an anti-slip edge, which is a strip-shaped structure protruding along the edge of the clamping plate.

[0011] Preferably, each end of the support arm is provided with a support block, and the support block is a rectangular plate structure.

[0012] Preferably, a reinforcing rib is provided at the connection between the connecting arm and the clamping arm body, and the reinforcing rib is used to enhance the structural strength of the left clamping arm.

[0013] In summary, this application includes the following beneficial technical effects:

[0014] 1. The linkage structure allows the left and right clamping arms to open and close synchronously, ensuring uniform force on the clamping plate and the pipe surface. The anti-slip edge increases friction, making it difficult for the pipe to slip or rotate even when the pipe surface is wet. At the same time, the precise hinge connection ensures high clamping alignment, firmly fixing the pipe and preventing loosening.

[0015] 2. The angle of the support arm can be adjusted through the positioning holes and fixing bolts to adapt to different installation environments. The adjusting column can also adjust the clamping height. The support block increases the contact area for more stable installation, and the reinforcing ribs enhance the structural strength. The whole structure is flexible, adaptable, sturdy, and durable, and is not easily deformed or damaged. Attached Figure Description

[0021] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0022] Reference Figure 1-4 This utility model provides a fire pipe connection bracket, including two support arms 1. The middle part of the two support arms 1 is connected to the connecting column 2. A linkage shaft 3 is installed on the connecting column 2. Two connecting rods 301 are hinged on the linkage shaft 3. The ends of the two connecting rods 301 away from the linkage shaft 3 are respectively hinged to a left clamping arm 4 and a right clamping arm 5. The left clamping arm 4 and the right clamping arm 5 are symmetrically arranged and cooperate to form a fire pipe clamping space.

[0023] Support arm 1 is the load-bearing foundation of the entire connecting frame. Two support arms 1 are fixed to connecting column 2 at the middle, forming a stable support frame that provides installation support and load-bearing support for subsequent clamping components. The linkage shaft 3 installed on connecting column 2 is the core of power transmission. When it is necessary to fix the fire-fighting pipe, rotating the linkage shaft 3 will cause the two connecting rods 301 hinged to it to swing together. These two connecting rods 301 pull the left clamping arm 4 and the right clamping arm 5 respectively. Due to their symmetrical arrangement, they will move towards or away from each other along the same trajectory: when moving towards each other, they gradually approach to form a clamping space, clamping the pipe; when moving in opposite directions, the clamping space increases, facilitating the insertion or removal of the pipe. Throughout the process, the support arm 1 provides stable load bearing, the connecting column 2 connects all components, the linkage shaft 3 and connecting rods 301 transmit power, and the left clamping arm 4 and right clamping arm 5 cooperate to complete the clamping, achieving stable positioning of the fire-fighting pipe.

[0024] In a preferred embodiment, an adjusting post 203 extends from the lower part of the connecting post 2, and a linkage joint 204 is provided at the lower end of the adjusting post 203. The linkage joint 204 is hinged to the left clamping arm 4 and the right clamping arm 5 respectively.

[0025] The adjusting column 203 extending from the lower part of the connecting column 2 serves both to extend the length of the connecting column 2 and to provide an installation position for the lower linkage connector 204, allowing adjustment of the clamping height according to the installation scenario. The linkage connector 204 is hinged to the left clamping arm 4 and the right clamping arm 5 respectively, becoming the fulcrum for their movement. When the linkage shaft 3 drives the two clamping arms to move via the connecting rod 301, the linkage connector 204 limits their rotation trajectory, preventing deviation or jamming during movement. Through the hinged engagement of the linkage connector 204 with the left and right clamping arms 5, the left clamping arm 4 and the right clamping arm 5 can precisely open and close around the linkage connector 204, ensuring a stable clamping space shape and improving the coaxiality and reliability of the pipe clamping.

[0026] In a preferred embodiment, the connecting column 2 is provided with a positioning hole 201, and a fixing bolt 202 is inserted into the positioning hole 201. The fixing bolt 202 is used to lock the relative position of the support arm 1 and the connecting column 2.

[0027] The positioning hole 201 on the connecting column 2 serves as the installation channel for the fixing bolt 202. The two are sized to fit each other, allowing the fixing bolt 202 to pass smoothly without loosening. During installation, first adjust the intersection angle and position of the two support arms 1 to find a suitable support state. Then, pass the fixing bolt 202 through the positioning hole 201 and tighten it. The fixing bolt 202, through its pressing action, locks the relative position of the support arm 1 and the connecting column 2, preventing displacement or rotation and maintaining the set support posture of the support arm 1. This satisfies the angle adjustment requirements under different installation environments while ensuring the stability of the support structure and preventing the support arm 1 from shifting and causing clamping failure when the connecting frame bears the weight of the pipe or is subjected to external forces.

[0028] In a preferred embodiment, the left clamping arm 4 includes a connecting arm 401, a clamping arm body 402, and a clamping plate 404. One end of the connecting arm 401 is hinged to the connecting rod 301, and the other end is fixedly connected to the clamping arm body 402. The clamping plate 404 is disposed at the end of the clamping arm body 402 facing the clamping space.

[0029] The left clamping arm 4 consists of a connecting arm 401, a clamping arm body 402, and a clamping plate 404, with clearly defined functions: one end of the connecting arm 401 is connected to the connecting rod 301, receiving the swinging power transmitted by the connecting rod 301, while the other end is fixed to the clamping arm body 402, transmitting the power thereto; the clamping arm body 402 is the main force-bearing component, driving the entire left clamping arm 4 in its opening and closing motion, while also providing an installation base for the clamping plate 404; the clamping plate 404 is designed to fit against the outer wall of the fire-fighting pipe, and when the clamping arm body 402 moves it close to the pipe, it will form surface contact with the pipe surface. Through the force transmission of the connecting arm 401, the load-bearing of the clamping arm body 402, and the direct contact of the clamping plate 404 with the pipe, the left clamping arm 4 forms a complete force transmission chain. When it cooperates with the right clamping arm 5, it can evenly apply the clamping force to the pipe surface, ensuring a firm clamping.

[0030] In a preferred embodiment, the clamping arm body 402 is provided with a hinge hole 403, which is adapted to be hinged with the linkage joint 204 of the adjusting column 203.

[0031] The hinge hole 403 on the clamping arm body 402 is perfectly matched to the linkage joint 204 at the lower end of the adjusting column 203, enabling a precise hinged connection. When the connecting rod 301 drives the connecting arm 401, the connecting arm 401 pulls the clamping arm body 402 to rotate around the hinge point between the hinge hole 403 and the linkage joint 204. The hinge hole 403 clearly defines the rotation center of the left clamping arm 4, allowing the clamping arm body 402 to perform a predictable arc-shaped movement with the clamping plate 404, without any skewing or offset. This precisely fitted hinge structure allows the opening and closing of the left clamping arm 4 and the right clamping arm 5 to be synchronized and symmetrical, further improving the stability of the clamping space and the clamping accuracy.

[0032] In a preferred embodiment, the edge of the clamping plate 404 is provided with an anti-slip edge 405, which is a strip-shaped structure protruding along the edge of the clamping plate 404.

[0033] The anti-slip edge 405 of the clamping plate 404 is a raised strip structure. When the clamping plate 404 comes into contact with the fire-fighting pipe, the anti-slip edge 405 will first adhere to the pipe surface. The raised strip design can embed into the tiny textures on the pipe surface, forming a mechanical interlocking effect. This structure can significantly increase the friction between the clamping plate 404 and the pipe, effectively preventing the pipe from sliding axially or rotating circumferentially within the clamping space. Even if the pipe surface is wet or oily, reliable clamping can be guaranteed. At the same time, the anti-slip edge 405 is distributed along the edge of the clamping plate 404, which will not affect the fit between the clamping plate 404 and the pipe, and can further limit the position of the pipe and prevent pipe displacement.

[0034] In a preferred embodiment, each end of the support arm 1 is provided with a support block 101, which is a rectangular plate structure.

[0035] The support block 101 at the end of the support arm 1 is rectangular, which increases the contact area with the mounting surface (such as a wall or bracket). When the support arm 1 provides support for the connecting frame, the support block 101 evenly distributes the weight of the connecting frame and the pipe borne by the support arm 1 onto the mounting surface, preventing damage caused by excessive local stress on the mounting surface due to insufficient contact area. The rectangular support block 101 also improves the fit with the mounting surface, reducing wobbling. Furthermore, the rectangular structure facilitates further fixing to the mounting surface with bolts, expansion bolts, and other fasteners, making the installation of the support arm 1 more stable.

[0036] In a preferred embodiment, a reinforcing rib 406 is provided at the connection between the connecting arm 401 and the clamping arm body 402. The reinforcing rib 406 is used to enhance the structural strength of the left clamping arm 4.

[0037] The connection point between the connecting arm 401 and the clamping arm body 402 is a stress concentration area. When clamping the pipe, the power transmitted by the connecting arm 401 and the reaction force of the pipe are concentrated here. The reinforcing ribs 406 can be firmly connected to the connecting arm 401 and the clamping arm body 402 to form a stable triangular structure, effectively dispersing the stress at the connection point and preventing deformation, cracking or breakage.
