Description

Technical Field

[0001] The utility model relates to the technical field of pipeline fixing devices, in particular to a pipeline fixing device. Background Art

[0002] Sewage pipes are the most common pipes used to discharge domestic sewage and industrial sewage. Sewage can flow into the sewage collection area through sewage pipes. However, during the installation of existing sewage pipes, it is necessary to first dig a pipe trench in the ground and then place the sewage pipe in the installation trench on the ground.

[0003] The patent with application number 202323010466.3 discloses a sewage pipe fixing device, including a pipe body and a base, a fastening mechanism is arranged above the base, the fastening mechanism includes an upper fixed semicircular ring and a lower fixed semicircular ring that are detachably connected, a buffer mechanism is arranged between the upper fixed semicircular ring and the lower fixed semicircular ring, and the pipe body is penetrated by the buffer mechanism. The utility model equips the fastening mechanism with a buffer mechanism, which can prevent the sewage pipe from shaking drastically during use, causing friction with the peripheral fastening mechanism, and reducing the service life of the pipe and the device.

[0004] Water in the pipe will vibrate during the flow. The above technical solution uses a buffer mechanism composed of a spring to buffer the pipe. Although the spring can buffer the vibration, the elastic force of the spring will cause the pipe to continue to shake, thereby amplifying the vibration borne by the pipe fixing seat, causing the bolts and nuts used for fixing on the pipe fixing seat to loosen more easily, resulting in poor stability of pipe fixing. Therefore, the present application provides a pipe fixing device to meet the needs. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a pipeline fixing device to solve the problem that the existing pipeline fixing seat is subjected to vibration, which makes the bolts and nuts used for fixing on the pipeline fixing seat more likely to loosen, and the stability of the pipeline fixing is poor.

[0006] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0007] A pipeline fixing device comprises a pipeline main body and a fixing frame symmetrically sleeved on the pipeline main body, wherein a first connecting plate and a second connecting plate are fixed to the two ends of the two fixing frames respectively, bolts are symmetrically arranged between the first connecting plate and the second connecting plate, and a fixing seat sleeved on the bolts is fixed to the bottom end of the first connecting plate, and positioning holes are opened in a circular array at the top end of the second connecting plate, a nut is threadedly sleeved on the top end of the bolt, and a positioning rod inserted in the positioning hole is elastically arranged at the bottom end of the nut.

[0008] Optionally, a rigid inner ring is fixed to the inner wall of the two fixing frames, and a hard rubber plate tightly sleeved on the pipe body is fixed to the inner wall of the rigid inner ring.

[0009] Optionally, a plurality of accommodating chambers are provided between the fixing frame and the rigid inner ring, and a rock wool insulation core is embedded in the accommodating chambers.

[0010] Optionally, baffles are symmetrically fixed on both sides of the inner wall of the accommodating bin, and the side walls of the baffles are in contact with the rock wool insulation core.

[0011] Optionally, a base is fixedly mounted on the bottom end of the fixing frame, and a plurality of drainage grooves are formed at the bottom end of the base.

[0012] Optionally, a mounting hole is formed at one end of the nut, and a plug hole passing through the mounting hole is formed on a side wall of the nut.

[0013] Optionally, the positioning rod is slidably inserted in the mounting hole, and a convex plate is fixed to the bottom end of the outer wall of the positioning rod.

[0014] Optionally, a spring located at the top of a convex plate is sleeved on the top of the positioning rod, and the bottom end of the convex plate abuts against the inner wall of the mounting hole.

[0015] Optionally, a latch is embedded in the side wall of the nut, the latch abuts against the bottom end of the positioning rod, the latch is inserted into the socket, and the latch is dampedly connected to the inner wall of the socket.

[0016] Optionally, a groove with a hexagonal structure is formed at the bottom end of the fixing seat, and the bottom end of the bolt is inserted into the groove.

[0017] Compared with the prior art, the utility model has at least the following beneficial effects:

[0018] In the above scheme, a fixing seat for axially positioning bolts is fixed at the bottom end of the first connecting plate, and positioning holes are opened in a ring array at the top end of the second connecting plate. The pin damping is inserted into the socket so that the bottom of the positioning rod is embedded in the mounting hole. The embedded pin and positioning rod will not affect the installation of the nut. After the nut is tightened on the bolt, the pin is pulled out of the socket, and the spring in the mounting hole squeezes the convex plate to insert the positioning rod into the positioning hole, thereby maintaining axial positioning between the nut and the second connecting plate, facilitating the positioning of the fixed bolt and nut, and avoiding the shaking of the nut due to vibration.

[0019] By fixing a hard rubber plate on the inner wall of the rigid inner ring, the hard rubber plate improves the friction between the fixing frame and the pipeline body, and the rock wool insulation core between the fixing frame and the rigid inner ring improves the protection effect of the supporting part of the pipeline body.
