Description

Technical Field

[0001] This utility model relates to the field of conduit fittings technology, and in particular to a conduit connector with a pre-embedded support rod. Background Technology

[0002] Conduit, also known as "building insulated electrical conduit," is simply a white, rigid PVC conduit used for wiring; it is corrosion-resistant, leak-proof, and for running electrical wires. It comes in three types: plastic conduit, stainless steel conduit, and carbon steel conduit.

[0003] The existing method involves directly embedding conduits into the wall during construction, while junction boxes connected to the conduits are embedded when the wall is built to their corresponding positions. This separate embedding method can easily cause the height and position of the junction boxes to shift due to the wall construction, affecting subsequent use. Furthermore, when embedding junction boxes, workers need to hold the junction boxes while constructing or pouring the wall, which not only makes it difficult to ensure the embedding accuracy of the junction boxes but also poses certain safety hazards.

[0004] Therefore, it is necessary to invent a conduit connector with a pre-embedded support rod to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide an electrical conduit connector with a pre-embedded support rod to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a conduit connector with a pre-embedded support rod, comprising a main rod and a side rod installed on the outside of the main rod. The bottom end of the side rod is provided with a bent pipe, and the bottom end of the bent pipe is provided with a junction box. The outer side wall and rear side of the junction box are provided with wire holes. The bottom end of the bent pipe is detachably inserted into the wire hole. The top end of the bent pipe is fixedly provided with a sleeve. The outer side wall of the sleeve is designed with an inclined structure. The inner side wall of the sleeve is surrounded by six arc-shaped positioning grooves. The bottom end of the side rod is fixedly provided with an insertion tube. The insertion tube is detachably inserted into one end of the sleeve. The outer side wall of the insertion tube is surrounded by six arc-shaped positioning blocks. The six positioning blocks correspond one-to-one with the six positioning grooves. The outer side wall of the sleeve is provided with two symmetrically distributed deformation grooves, both of which are strip-shaped structures. The outer side of the sleeve is slidably provided with a threaded sleeve. The top end of the threaded sleeve is fixedly provided with a pressure sleeve, which is slidably sleeved on the outer side of the sleeve.

[0007] Preferably, an annular seat is fixedly provided at one end of the insertion tube near the side rod, and the outer diameter of the annular seat is consistent with the inner diameter of the pressure sleeve.

[0008] Preferably, the bottom end of the bent pipe is fixedly provided with an annular insert, the bottom end of the outer wall of the insert is provided with an inclined structure, and the top of the insert is fixedly provided with an annular stop, and the stop fits against the outer wall of the junction box.

[0009] Preferably, the top of the outer side wall of the insert block is provided with an inclined contact surface, and the contact surface fits into the slot of the wire hole, and the bottom of the inner side wall of the insert block is provided with a plurality of strip grooves.

[0010] Preferably, a reinforcing rib is fixedly provided at the connection between the main rod and the side rod, and a connecting sleeve is fixedly provided at the top end of the main rod.

[0011] Preferably, the angle of the bend is 135°, and the included angle between the main rod and the side rod is 135°.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] 1. This utility model sets up a main rod, side rods, bends, and junction boxes. The main rod and side rods form a three-way structure, and the bends connect the junction boxes to the side rods. During the pre-embedding process, the main rod, side rods, and bends form the main structure of the conduit. The junction boxes are directly connected to the main structure of the conduit through the bends. Positioning and pre-embedding are performed before the wall is built, eliminating the need for workers to manually position the junction boxes during the wall construction process. This reduces construction difficulty and improves the pre-embedding accuracy of the junction boxes. Furthermore, the bends and side rods can rotate relative to each other, allowing the angle of one end of the bends to be adjusted. This facilitates adjusting the bend angle according to the layout between the conduit and the junction boxes, thereby improving the device's pre-embedding positioning of junction boxes at different locations.

[0014] 2. This utility model, by setting up a sleeve, a plug, and a pressure sleeve, allows for the connection between the bent pipe and the side rod through the cooperation of the sleeve and the plug. Furthermore, the sleeve deforms inward under the squeezing action of the pressure sleeve to clamp the plug, thereby improving the connection stability between the two. At the same time, one end of the plug is provided with an annular seat, and the pressure sleeve can be fitted onto the outside of the annular seat to form a reinforced protective layer on the outside of the sleeve and the plug, thereby improving the structural strength of the side rod and the bent pipe and preventing damage and deformation during wall construction. By setting up a plug block and a wire hole, the plug block at the bottom of the bent pipe can be directly inserted into the wire hole on the outside of the junction box to achieve a quick connection between the bent pipe and the junction box, thus facilitating the rapid installation of the junction box.

[0022] 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.

[0023] This utility model provides, for example Figure 1-6 The cable conduit connector shown includes a main rod 1 and a side rod 2 installed on the outside of the main rod 1. The bottom end of the side rod 2 is provided with a bend 3. The angle of the bend 3 is set to 135°. The included angle between the main rod 1 and the side rod 2 is 135°. The bend 3 and the side rod 2 can rotate relative to each other, so that the bottom end of the bend 3 switches from a vertical state to a horizontal state.

[0024] The bottom end of the bent pipe 3 is provided with a wire box 4. The outer side wall and the rear side of the wire box 4 are provided with wire holes 5. The bottom end of the bent pipe 3 is detachably inserted into the wire hole 5. The top end of the bent pipe 3 is fixedly provided with a sleeve 6. The outer side wall of the sleeve 6 is designed with an inclined structure. The inner side wall of the sleeve 6 is surrounded by six arc-shaped positioning grooves 7. The bottom end of the side rod 2 is fixedly provided with an insertion tube 8. The insertion tube 8 is detachably inserted into one end of the sleeve 6. The outer side wall of the insertion tube 8 is surrounded by six arc-shaped positioning blocks 9. The six positioning blocks 9 correspond one-to-one with the six positioning grooves 7. The outer side wall of the sleeve 6 is provided with two symmetrically distributed deformation grooves 10. Both deformation grooves 10 are designed with a strip structure. During the sliding process, the pressure sleeve 11 squeezes the inclined surface of the outer side of the sleeve 6, causing the sleeve 6 to deform inward along the deformation grooves 10. After deformation, the sleeve 6 clamps the insertion tube 8, thereby improving the connection stability between the sleeve 6 and the insertion tube 8.

[0025] A threaded sleeve 12 is slidably provided on the outer side of the sleeve 6 via a thread. A pressure sleeve 11 is fixedly provided at the top of the threaded sleeve 12. The pressure sleeve 11 is slidably sleeved on the outer side of the sleeve 6. An annular seat 13 is fixedly provided at one end of the insertion tube 8 near the side rod 2. The outer diameter of the annular seat 13 is the same as the inner diameter of the pressure sleeve 11. After the inner wall of the pressure sleeve 11 fits against the outer wall of the annular seat 13, it forms a thickened protective layer on the outer side of the sleeve 6 and the insertion tube 8 to improve the connection strength and stability between the two.

[0026] The bottom end of the bend 3 is fixed with a ring-shaped plug 14. The bottom end of the outer wall of the plug 14 is set with an inclined structure. The top of the plug 14 is fixed with a ring-shaped stop 15, and the stop 15 is in contact with the outer wall of the junction box 4. The top of the outer wall of the plug 14 is provided with an inclined contact surface 16, and the contact surface 16 is in contact with the slot of the wire hole 5. The contact surface 16 on the outer side of the plug 14 presses the slot of the wire hole 5, so that the plug 14 is subjected to a force away from the wire hole 5, so that the stop 15 is in close contact with the surface of the junction box 4. The friction between the stop 15 and the junction box 4 prevents the junction box 4 from rotating.

[0027] The bottom of the inner side wall of the insert 14 is provided with a plurality of strip grooves 17. The strip grooves 17 are provided so that the insert 14 can deform when it is squeezed by the wire hole 5, so that the insert 14 can be inserted into the wire hole 5.

[0028] A reinforcing rib 18 is fixedly provided at the connection between the main rod 1 and the side rod 2. The reinforcing rib 18 is used to improve the connection strength between the main rod 1 and the side rod 2. A connecting sleeve 19 is fixedly provided at the top of the main rod 1. The connecting sleeve 19 is used to connect the main rod 1 and the conduit. It should be noted that the inner diameter of the connecting sleeve 19 is the same as the outer diameter of the main rod 1, and the inner diameter of the connecting sleeve 19 is the same as the outer diameter of the standard conduit.

[0029] Working principle of this utility model:

[0030] During installation, the main pole 1 is connected to the conduit via a connecting sleeve 19. The main pole 1 and the conduit are arranged according to wiring requirements. The main pole 1 is installed at the location where the junction box 4 needs to be installed in the conduit. After the main pole 1 and conduit are installed, the sleeve 6 at one end of the bend 3 is fitted onto the outside of the insert 8 at one end of the side pole 2. The angle of the bend 3 is adjusted according to the position between the junction box 4 and the main pole 1 to ensure that the junction box 4 can be embedded in the wall after the wall is constructed. After the position of the bend 3 and the side pole 2 is adjusted, the... The threaded sleeve 12, under the action of the thread, drives the pressure sleeve 11 to slide along the outside of the sleeve 6. During the sliding process, the pressure sleeve 11 squeezes the inclined surface on the outside of the sleeve 6, causing the sleeve 6 to deform inward along the deformation groove 10. After deformation, the sleeve 6 clamps the insertion tube 8, thereby improving the connection stability between the sleeve 6 and the insertion tube 8. The threaded sleeve 12 continues to rotate until the pressure sleeve 11 is fitted onto the outside of the annular seat 13. At this time, the pressure sleeve 11 forms a thickened protective layer on the outside of the sleeve 6 and the insertion tube 8. To further enhance the connection stability and strength between the two, after the bend 3 is connected to the side rod 2, the junction box 4 is placed at one end of the bend 3, so that the wire hole 5 on the junction box 4 corresponds to the plug 14 at the bottom of the bend 3. Press the junction box 4 and the bend 3 to bring them closer together. At this time, the inclined surface of the bottom outer side of the plug 14 is squeezed by the groove of the wire hole 5, causing the plug 14 to deform along the strip groove 17. Then the plug 14 is inserted into the wire hole 5, and then the stop block 15 and the outer wall of the junction box 4 are connected. When the junction box 4 and the bend 3 are in place, the force applied to the junction box 4 and the bend 3 is stopped. At this time, the plug 14 undergoes a restorative deformation under its own elastic potential energy. The contact surface 16 on the outer side of the plug 14 presses against the slot of the wire hole 5, so that the plug 14 is subjected to a force away from the wire hole 5, so that the stop 15 is tightly attached to the surface of the junction box 4. At this time, the junction box 4 and the bend 3 are connected, and the friction between the stop 15 and the junction box 4 prevents the junction box 4 from rotating, so as to ensure that the junction box 4 will not shift during the wall construction process.

[0031] The bend 3 can rotate during installation. When the bottom end of the bend 3 is parallel to the main rod 1, it can be connected to the wire hole 5 at the bottom of the junction box 4. When the bottom end of the bend 3 is perpendicular to the main rod 1, it can be connected to the wire hole 5 on the rear side of the junction box 4, so that the junction box 4 can be laid out as needed.

[0032] When the device is pre-embedded and positioned, if no conduit is installed below the device, a support rod with the same diameter as the conduit can be used to support the main rod 1.

[0033] It should be noted that in this embodiment, the inner diameter and specifications of the main rod 1, side rod 2 and bend 3 are all set to the standard dimensions in this technical field. The materials of the main rod 1, side rod 2 and bend 3 can be one of PVC, stainless steel and other metals, and are not limited here. The junction box 4 is set to one of the 86 junction box, 120 junction box and 118 junction box in the prior art, and is not limited here.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present 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 the present utility model should be included within the protection scope of the present utility model.
