Description

Technical Field

[0001] This utility model relates to the field of fire arrestor rings, and in particular to an auxiliary mounting bracket for fire arrestor rings. Background Technology

[0002] Fire collars (also called fireproof collars) are made of metal shells filled with flame-retardant expanding core material. They are fitted onto the outer wall of rigid polyvinyl chloride (PVC) pipes and fixed to the floor or wall. When a fire occurs, the core material expands rapidly due to heat, squeezing the UPVC pipe and sealing the pipe opening in a short time, preventing the fire from spreading along the opening. This product has a compact structure, beautiful appearance, and organically combines leak prevention and fire protection measures.

[0003] However, during installation, the fire arrestor ring is often installed at a high position, which is very inconvenient for construction workers to hold the fire arrestor ring with one hand and install it with the other. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide an auxiliary mounting bracket for fire arresters.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: This utility model discloses an auxiliary mounting bracket for a fire arrestor ring, comprising a base plate and a base column. The base column is disposed under the base plate, and a hollow column is disposed on the base plate. The hollow column is fixedly connected to one side of the base plate, and a telescopic column is sleeved inside the hollow column. Several limiting holes are vertically and evenly disposed on the telescopic column, and a limiting device is disposed at the top of the hollow column to restrict the vertical movement of the telescopic column. A support frame is disposed at the top of the telescopic column.

[0006] As a preferred embodiment of this utility model, the limiting assembly includes a pull ring, a housing, a spring, a limiting rod, and a limiting plate. The limiting plate is fixed to the outer end face of the hollow column. The housing is disposed on the side of the limiting plate. One end of the limiting rod passes through the limiting plate and extends into the interior of the limiting hole. The other end of the limiting rod passes through the side of the housing and is connected to the pull ring. The spring is sleeved between the inner wall of the housing and the limiting plate.

[0007] As a preferred technical solution of this utility model, the support frame is set on the side of the telescopic column that is not in the space above the base plate. The support frame is U-shaped in general, and its inner diameter is slightly larger than the pipe diameter but not larger than the outer diameter of the fire arrestor ring.

[0008] As a preferred embodiment of this utility model, a base is provided below the bottom column, and the bottom area of ​​the base is larger than the bottom area of ​​the bottom column.

[0009] As a preferred embodiment of this utility model, an anti-slip rubber pad is provided under the base.

[0010] As a preferred embodiment of this utility model, the bottom column is disposed at the four ends below the bottom plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. Pull the pull ring of the limit device. The spring is compressed and contracts, causing the limit rod to disengage from the limit hole of the telescopic column. After unlocking, the telescopic column can freely rise and fall within the hollow column. After adjusting to the required height (matching the pipe installation position), release the pull ring. The spring pushes the limit rod to automatically insert into the corresponding limit hole, achieving rigid fixation of the telescopic column. At this time, the bracket supports the weight of the fire arrestor ring and maintains its horizontal state. The installer does not need to manually lift the fire arrestor ring and can perform pipe connection or fixing operations with both hands. 2. The entire support structure is supported on the floor or ground by the base column, and the base and anti-slip pad work together to prevent the support structure from sliding.

[0013] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0014] In the attached diagram, all identical reference numerals refer to the same components.

[0015] like Figure 1-4 As shown, this utility model provides an auxiliary mounting bracket for a flame arrestor ring. In this invention, the mounting frame includes a horizontal base plate 1 and four base columns 2 vertically fixed to the bottom surface of the base plate 1 by welding or high-strength bolts. A vertical hollow column 3 is welded / bolted to the top surface of the base plate 1, and a height-adjustable telescopic column 4 is nested inside the hollow column 3 with a precise clearance fit. Multiple sets of equally spaced limiting holes 5 are opened on the side of the telescopic column 4, and a U-shaped support frame 7 is welded / bolted to the top. The support frame 7 is located on the side of the telescopic column 4 away from the center of the base plate 1, and its U-shaped inner diameter is slightly larger than the outer diameter of the pipe but does not exceed the outer diameter of the flame arrestor ring. A limiting device 6 is provided at the top of the hollow column 3 to lock the height of the telescopic column 4.

[0016] The limiting device 6 consists of a housing 62, a spring 63, a limiting rod 64, a limiting plate 65, and a pull ring 61. The limiting plate 65 is fixed to the hollow column 3, and the metal housing 62 is welded and fixed to one side of the limiting plate 65. One end of the limiting rod 64 passes through the limiting plate 65 and is inserted into the limiting hole 5 of the telescopic column 4, while the other end is fixedly connected to the external pull ring 61 by welding. The spring 63 is sleeved between the limiting plate 65 and the pull ring 61, providing elastic force for automatic reset. Under normal conditions, the spring 63 pushes the limiting rod 64 into the limiting hole 5, and pulling the pull ring 61 can release the lock.

[0017] The columns are distributed at the four corners of the bottom surface of the base plate 1. The bottom of the columns 2 is detachably connected to the rectangular base 13 by bolts. The area of ​​the base 13 is significantly larger than the cross-section of the column 2 to increase the support surface. The bottom surface of the base 13 adopts a groove-embedded structure and uses weather-resistant adhesive to fix the anti-slip rubber pad 14, thereby increasing the friction coefficient and preventing the support from shifting during construction.

[0018] The working principle of this utility model is as follows: The construction worker pushes the pipe into the inner side of the support frame 7 using this utility model. The worker then pulls the pull ring 61 of the limiting device 6 outward, causing the spring 63 to extend and disengage the limiting rod 64 from the limiting hole 5 of the telescopic column 4. After unlocking, the telescopic column 4 can freely rise and fall within the hollow column 3. After adjusting to the required height (matching the pipe installation position), the pull ring 61 is released, and the spring 63 resets, pushing the limiting rod 64 to automatically insert into the corresponding limiting hole 5, achieving rigid fixation of the telescopic column 4. At this time, the bracket supports the weight of the fire arrestor ring and maintains its horizontal state. The installer does not need to manually lift the fire arrestor ring and can perform pipe connection or fixing operations with both hands. After installation, the limiting device 6 is unlocked, and the telescopic column 4 is lowered to retract the bracket.

[0019] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
