Description

Technical Field

[0001] The utility model relates to the technical field of electrical conduit connection devices, in particular to a PVC electrical conduit which is easy to install. Background Art

[0002] The electrical conduit is an external conduit for installing wires and cables. It is a PVC pipe used to protect wires and cables. It can prevent wires and cables from being damaged by the environment and extend the service life of the cables. However, the existing electrical conduits are generally integrated round tubes, and the PVC pipe is connected and installed by plugging it. Although this plug-in method looks simple, it is difficult to plug in due to the problem of pipe diameter, which is relatively time-consuming. In addition, the possibility of reusing the conduit after it needs to be removed during maintenance operations is basically non-existent, which leads to a waste of materials. In this regard, the present application specifically proposes a PVC electrical conduit that is easy to install, which is easy to install and can be reused. Utility Model Content

[0021] The following is combined with Figure 1-8 The specific implementation methods of the utility model are further described in detail.

[0022] Embodiment 1, the technical solution is that when the present application is used, the upper arc sleeve 3 and the lower arc sleeve 2 are provided to form an electrical sleeve, and can be respectively clamped on the upper and lower sides of the pipe 1, and fastened by the limit device 9 in cooperation with the limit hole 8 on the positioning column 5, so that the connection and installation of the pipe 1 can be completed conveniently, the operation is simple, the installation time is saved, and the present application can be used multiple times, avoiding the waste of materials. When the present application is used, a sealing groove 22 is arranged on the lower arc sleeve 2, and the sealing strip 24 on the upper arc sleeve 3 can be clamped with the sealing groove 22 and pressed against the sealing pad 23, so as to ensure the sealing of the connection between the upper arc sleeve 3 and the lower arc sleeve 2, and prevent external moisture, water stains and the like from entering the pipe 1. The upper clamp ring 20 and the lower clamp ring 21 are clamped with the clamping groove 19 on the pipe 1, which not only ensures the connection strength of the upper arc sleeve 3 and the arc sleeve with the pipe 1, but also can play a sealing role.

[0023] Embodiment 2, based on embodiment 1, specifically, when in use, the present application clamps the lower clamping ring 21 in the inner wall of the lower arc sleeve 2 with the clamping groove 19 on the pipe 1, and then the upper arc sleeve 3 is connected correspondingly with the lower arc sleeve 2 and clamped on the upper edge of the pipe 1.

[0024] When connecting the upper arc sleeve 3 and the lower arc sleeve 2, the positioning column 5 on the upper mounting block 4 is plugged into the positioning hole 7 on the lower mounting block 6 in a one-to-one correspondence, and then the upper arc sleeve 3 is automatically positioned and clamped on the upper edge of the pipe 1. At the same time, the upper clamping ring 20 in the inner wall of the upper arc sleeve 3 will also be automatically clamped in the clamping groove 19. The upper clamping ring 20 and the lower clamping ring 21 form a ring-shaped clamp in the clamping groove 19, which ensures the strength of the connection while also having a sealing effect. After the positioning column 5 is inserted into the positioning hole 7, it is only necessary to release the restriction of the limiting device 9 so that the limiting rod 11 is inserted into the limiting hole 8 on the positioning column 5 to complete the installation operation of the pipe 1 connection of this application. Specifically, as shown in the accompanying drawings of the specification Figure 4 and Figure 6As shown, at this time, the positioning column 5 is plugged into the positioning hole 7, but the limiting rod 11 of the limiting device 9 is still in a restricted state and cannot cooperate with the limiting hole 8, and at this time the spring 13 located between the lower mounting block 6 and the baffle 12 is in a stretched state. In order to quickly complete the connection of this application, it is only necessary to pull out the pin shaft 16 in the pin hole 15, and then the pin shaft 16 is disengaged from the cooperation with the long groove 14, and then the limiting rod 11 loses its restriction, and the spring 13 originally in a stretched state will automatically shrink. The automatic shrinkage of the spring 13 will drive the limiting rod 11 to slide along the through hole 10 to the limiting hole 8, and then the limiting rod 11 is inserted into the limiting hole 8, and then the positioning column 5 is restricted in the positioning hole 7, and the upper arc sleeve 3 and the lower arc sleeve 2 are fastened. Connection is completed.

[0025] Correspondingly, when the upper arc sleeve 3 and the lower arc sleeve 2 need to be separated during maintenance work, it is only necessary to pull the limit rod 11 outward to disengage from the limit block, and after the pin hole 15 corresponds to the long groove 14, the pin shaft 16 is inserted into the pin hole 15 again, that is, the pin shaft 16 is inserted into the long groove 14 again, and then the limit rod 11 is restricted to a position separated from the limit hole 8, and the upper arc sleeve 3 and the lower arc sleeve 2 can be easily separated.

[0026] Embodiment 3, on the basis of embodiment 2, the long groove 14 has a certain length, which is extremely convenient for inserting the pin shaft 16, and a guide block 17 is provided in the through hole 10 to cooperate with the guide groove 18 on the limit rod 11, thereby limiting the limit rod 11 to move only along the axial direction of the through hole 10, that is, horizontally, to avoid the limit rod 11 from rotating and affecting the corresponding relationship between the pin shaft 16 and the long groove 14.
