[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.
[0021] Traditional cable routing elbows bend the cable to a certain degree and pass it through the elbow. The elbow can protect the cable. However, if the bending angle is not accurate or the bending radius does not meet the requirements, it may cause difficulties in cable installation or even damage the cable. In narrow spaces or complex wiring environments, the presence of elbows makes wiring operations more difficult, increasing the difficulty of construction and time costs.
[0022] In view of this, the present invention provides a large-diameter waterproof cable routing elbow that is easy to construct. The first round pipe and the second round pipe are fixed together by a connecting device so that the two round pipes form an elbow. When the first round pipe and the second round pipe are not forming an elbow, the two round pipes are in a vertical state, and the cable can easily pass through the two round pipes, which facilitates the installation of the cable and avoids damage to the cable, thereby reducing the difficulty of construction and time cost.
[0023] Example 1: By Figure 1 , 2As shown in points 3 and 4, a large-diameter waterproof cable routing elbow that is easy to construct includes a first circular pipe 1, a second circular pipe 3 rotatably connected to the inner wall of the first circular pipe 1, and a connecting device 2 provided at the bottom of the first circular pipe 1. The connecting device 2 includes: a sliding groove 21, fixedly connected to the bottom of the first circular pipe 1 on the side away from the second circular pipe 3; two first bolts 22, both threadedly connected to the inner wall of the sliding groove 21; a diagonal rod 23, slidably engaged with the inner wall of the sliding groove 21 and in contact with the outer wall of the two first bolts 22; and a U-shaped groove 24, fixedly connected to the outer wall of the second circular pipe 3 and in contact with the bottom of the diagonal rod 23. The diagonal rod 23 is pushed into the U-shaped groove 24, and the two first bolts 22 are twisted and rotated to fit against the outer wall of the diagonal rod 23. The diagonal rod 23, together with the U-shaped groove 24 and the sliding groove 21, fixes the first circular pipe 1 and the second circular pipe 3 together.
[0024] In the specific implementation process, it is worth noting that the angle between the first round tube 1 and the second round tube 3 can be adjusted. The top of the U-shaped groove 24 is in a convex state, which can limit the movement of the inclined rod 23. The inclined rod 23 is pushed into the U-shaped groove 24. The two first bolts 22 are twisted to move upward and fit with the inclined rod 23. The two first bolts 22 restrict the movement of the inclined rod 23. The bottom of the inclined rod 23 is machined into a flat surface, so it can only make translational movements inside the U-shaped groove 24.
[0025] Furthermore, an installation sleeve 8 is fixedly connected to the outer wall of the first circular tube 1, the inner wall of the installation sleeve 8 is fixedly connected to the outer wall of the second circular tube 3, and a connecting cover 9 is fixedly connected to one side of the installation sleeve 8.
[0026] In the specific implementation process, it is worth noting that the installation sleeve 8 is made of rubber and the connecting cover 9 is a telescopic tube structure with flexible telescopic characteristics;
[0027] Furthermore, the outer walls of the first circular tube 1 and the second circular tube 3 are both machined with external threads 6, and a connecting sleeve 7 is threaded to the outer wall of the external thread 6 at the bottom of the second circular tube 3.
[0028] In the specific implementation process, it is worth noting that the first circular pipe 1 and the second circular pipe 3 can be connected to the external pipe through the connecting sleeve 7;
[0029] Specifically, when using this convenient large-diameter waterproof cable routing elbow, when the first round pipe 1 is in a vertical state, the cable is directly passed through the second round pipe 3 and the first round pipe 1, causing the first round pipe 1 to rotate 90 degrees, which in turn causes the inclined rod 23 to rotate, so that the bottom of the inclined rod 23 enters the U-shaped groove 24, pushing the inclined rod 23 to move towards the U-shaped groove 24. When the inclined rod 23 is in contact with the inner wall of the slide groove 21 near the U-shaped groove 24, the two first bolts 22 are turned and rotated respectively. The first bolts 22 move upward, restricting the inclined rod 23 from moving horizontally inside the slide groove 21. The inclined rod 23, through the slide groove 21 and the U-shaped groove 24, fixes the first round pipe 1 and the second round pipe 3 together, so that the first round pipe 1 and the second round pipe 3 form an elbow. During the rotation of the first round pipe 1, the connecting cover 9 is opened by the installation sleeve 8. The first round pipe 1 and the second round pipe 3 can be fixed with other pipes by the connecting sleeve 7 and the external thread 6.
[0030] Example 2: From Figure 1 , 4 As shown in section 5, the outer wall of the second circular tube 3 is provided with a waterproof device 4. The waterproof device 4 includes: two connecting rods 41, both rotatably connected to the bottom of the outer wall of the second circular tube 3; two waterproof covers 42, each fixedly connected to one end of the two connecting rods 41; multiple side plates 43, each fixedly connected to the outer wall of the two waterproof covers 42; and multiple second bolts 44, each threadedly connected to the inner wall of the multiple front side plates 43. When the two waterproof covers 42 are rotated inward by ninety degrees, the multiple second bolts 44 are twisted to fix the two waterproof covers 42 together, thus protecting the inner first circular tube 1 and the second circular tube 3.
[0031] In the specific implementation process, it is worth noting that after rotating the two waterproof covers 42 ninety degrees, the two waterproof covers 42 are fixedly connected together by twisting multiple second bolts 44 respectively.
[0032] Furthermore, multiple sealing strips 5 are fixedly connected to the top of the two waterproof covers 42 respectively;
[0033] In the specific implementation process, it is worth noting that the sealing strip 5 is made of rubber, which achieves a sealing effect after the two waterproof covers 42 are fixed together;
[0034] Specifically, based on the above embodiment one, the two waterproof covers 42 are pushed to rotate around the connecting rod 41. After the two waterproof covers 42 are put together, multiple second bolts 44 are twisted to rotate. The multiple second bolts 44 fix the two waterproof covers 42 together. The two waterproof covers 42 protect the inner first round tube 1 and the second round tube 3. At the same time, the sealing strip 5 seals the space between the two waterproof covers 42.
[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
