Description

Technical Field

[0001] The utility model relates to the technical field of fire-fighting pipelines, in particular to a fire-fighting pipeline fixing frame used in fire-fighting engineering. Background Art

[0002] Firefighting pipes refer to pipe materials used in firefighting to connect firefighting equipment and devices and to transport firefighting water, gas or other media. Due to special needs, the thickness and material of firefighting pipes have special requirements and are sprayed with red paint. Firefighting pipes are usually fixed to the ceiling through a fixing frame.

[0003] Most of the existing fixing frames fix the fire pipes by bolts, nuts and fixing rings, which are prone to loosening. During installation, the fire pipes need to be fixed with the cooperation of multiple bolts, which is inconvenient to install. When the installation angle of the fixing frame is not suitable, it needs to be disassembled and reinstalled, and the process is cumbersome. Therefore, we propose a fire pipe fixing frame for fire engineering to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to provide a fire protection pipe fixing frame for fire protection engineering to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a fire-fighting pipe fixing frame for fire-fighting engineering, comprising a first fixing plate and a second fixing plate, the first fixing plate is located above the second fixing plate, screws are rotatably installed on both sides of the second fixing plate, worm gears are fixedly installed on the lower parts of the two screws, a rotating shaft is provided inside the second fixing plate, worm gears are fixedly installed on both sides of the rotating shaft, the two worm gears are meshingly connected with the worm gears, a third fixing plate is threadedly penetrated on the outer surfaces of the two screws, a second clamping block is fixedly installed on the middle part of the top end of the third fixing plate, a fourth fixing plate is rotatably installed on the top ends of the two screws, a first clamping block is fixedly installed on the middle part of the bottom end of the fourth fixing plate, a rotating disk is fixedly installed on the middle part of the top end of the fourth fixing plate, and the rotating disk penetrates one side of the first fixing plate.

[0006] Preferably, a gear is fixedly installed on the top of the rotating disk, and the gear is rotatably installed on the middle part of the first fixed plate. A tooth plate is slidably clamped on one side of the middle part of the first fixed plate, and the tooth plate is meshingly connected with the gear. Two symmetrically distributed springs are fixedly installed on one side of the tooth plate, and the other ends of the two springs are fixedly installed on one side of the middle part of the first fixed plate. A pull rod is fixedly installed on one side of the middle part of the tooth plate, and one side of the pull rod passes through the first fixed plate.

[0007] Preferably, a cavity is opened in the middle of the second fixing plate, the bottom ends of the two screw rods are rotatably mounted on the lower surface of the cavity, and the rotating shaft is rotatably mounted inside the cavity.

[0008] Preferably, two symmetrically distributed telescopic rods are fixedly mounted on the middle part of one side of the first fixed plate, and the driving ends of the two telescopic rods are fixedly mounted on one side of the toothed plate.

[0009] Preferably, both ends of the rotating shaft pass through the second fixing plate, and both ends of the rotating shaft are fixedly mounted with handles.

[0010] Preferably, two symmetrically distributed fixing blocks are fixedly mounted on both sides of the first fixing plate.

[0011] Preferably, limiting rods are fixedly mounted at the four corners of the top end of the second fixing plate, and the top end of the limiting rods is fixedly mounted on the bottom end of the fourth fixing plate.

[0012] Preferably, a pull ring is fixedly mounted on one end of the pull rod passing through the first fixing plate.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. By setting a worm wheel and a worm, when the rotating shaft drives the worm wheel and the worm to rotate, the screw is rotated, that is, the second clamping block moves upward to clamp and fix the fire pipe, so that the structure has self-locking, and the fire pipe can be fixed by only turning the handle once, which is convenient for installation and avoids the loosening of the existing fire pipe when it is fixed only by bolts and nuts;

[0015] 2. By setting gears and toothed plates, when the angle of the fire-fighting pipe needs to be adjusted, the fire-fighting pipe can be rotated by pulling the pull ring to make the toothed plate move away from the gear. When the appropriate angle is reached, the pull ring can be released, and the toothed plate can be reset under the reaction force of the spring to engage and limit the position with the gear to prevent the fire-fighting pipe from continuing to rotate. This solves the problem that the angle of the existing fixing frame is fixed. When the angle needs to be adjusted, the fixing frame needs to be disassembled and reinstalled.

A toothed plate 13 is slidably clamped on one side of the middle of the first fixed plate 1, and the toothed plate 13 is meshed and connected with the gear 12. Two symmetrically distributed springs 132 are fixedly installed on one side of the toothed plate 13, and the other ends of the two springs 132 are fixedly installed on one side of the middle of the first fixed plate 1. A pull rod 133 is fixedly installed on one side of the middle of the toothed plate 13, and one side of the pull rod 133 passes through the first fixed plate 1.
