Abstract
Description
Technical Field
[0001] This utility model relates to the field of construction machinery, and in particular to a connection and reinforcement device for the joint position of building conduits. Background Technology
[0002] KBG conduits are widely used in electrical wiring installations in residential, commercial, and industrial buildings. KBG conduits are typically made of high-quality steel with a galvanized surface, providing excellent corrosion resistance. KBG conduits are connected using specialized crimping tools, eliminating the need for threading, simplifying the installation process, and ensuring the mechanical strength of the joints.
[0003] Chinese patent CN113814923A discloses a conduit clamp, which includes a fixed handle, a retaining ring, and an operating handle. The fixed handle is arranged radially along the retaining ring, and the retaining ring is provided with at least two pressure adjustment components along its circumference. The part of the fixed handle near the connecting end of the fixed handle is a hollow tube structure, and an elastic pressure component is provided inside the hollow tube structure. The elastic pressure component passes through the retaining ring and is adjustablely arranged on the retaining ring along its radial position. The operating handle is rotatably connected to the fixed handle.
[0004] When using the conduit clamp in the relevant technology, the fixed handle and the operating handle are brought closer together, so that the operating handle pushes out the elastic pressing component, and with the pressing adjustment component, the KBG pipe and the connecting sleeve are pressed and fixed together to achieve connection and fixation.
[0005] However, during the process of pushing the elastic pressing component out with the operating handle, the extension amount of the elastic pressing component cannot be controlled, which can easily lead to uneven reinforcement force, resulting in damage to the conduit joint and affecting the molding quality. This needs to be improved. Utility Model Content
[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a connection and reinforcement device for the joint position of building conduits, which has the effect of ensuring the forming quality of the conduit joint position.
[0007] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a connection and reinforcement device for the joint position of building conduit, comprising:
[0008] The chuck is U-shaped and is used for inserting conduit connectors;

[0011] A movable handle is rotatably connected between a pair of connecting plates;
[0012] A fixed ejector pin is horizontally threaded to the end of the chuck opposite the support handle.
[0013] A sliding pin is horizontally slidably connected to one end of the chuck near the support handle and extends into the support handle. A push rod is provided on the sliding pin, penetrating the lower end face of the support handle. A spring is sleeved on the sliding pin in front of the push rod, and the push rod is located at the front end of the movable handle, allowing the movable handle to be flipped or pushed.
[0014] The bottom ejector pin is vertically threaded and connected to the middle of the chuck;
[0015] The limiting mechanism includes a limiting rod, a baffle, a fork, and a nut. The limiting rod vertically penetrates the support handle, and a limiting groove is provided on the support handle along its length. The baffle is disposed on the outer wall of the limiting rod and is used to abut against the lower end face of the support handle. The fork is disposed at the lower end of the limiting rod and is used to abut against the movable handle. The nut is threaded to the limiting rod and is used to press against the upper end face of the support handle.
[0016] In a preferred embodiment, the present invention can be further configured such that: the chuck is provided with a tube for inserting the support handle, and the tube is provided with a screw for fixing the support handle.
[0017] In a preferred embodiment, the present invention can be further configured such that the length of the movable handle is less than the length of the supporting handle.

[0028] The present invention will be further described in detail below with reference to the accompanying drawings.
[0029] like Figure 1 , Figure 2 As shown, a connection and reinforcement device for the joint position of a building conduit includes a chuck 1, a support handle 2, a connecting piece 3, a movable handle 4, a fixed pin 5, a sliding pin 6, a bottom pin 7, and a limiting mechanism 8.
[0030] like Figure 1 , Figure 2 As shown, the chuck 1 is U-shaped and is used for inserting the conduit connector. The support handle 2 is horizontally set on the outer wall of one end of the chuck 1. The chuck 1 is provided with a tube 11 for inserting the support handle 2, and the tube 11 is provided with a screw 12 for fixing the support handle 2.
[0031] like Figure 1 , Figure 2 As shown, the connecting pieces 3 are disposed on the outer walls of both sides of the support handle 2 near the chuck 1, and the movable handle 4 is rotatably connected between a pair of connecting pieces 3.
[0032] like Figure 1 , Figure 2 As shown, the length of the movable handle 4 is less than the length of the support handle 2, so the end of the support handle 2 can be held, preventing the hand from being pinched when the support handle 2 and the movable handle 4 are close together. The support handle 2 is provided with a hook 21, and the end of the movable handle 4 is provided with a hanging rod 41 for the hook 21 to be hooked, which can realize the storage and fixation of the movable handle 4 after it is flipped over, making it convenient for storage and transportation.
[0033] like Figure 1 , Figure 2 As shown, the fixed ejector pin 5 is horizontally threaded to one end of the chuck 1 away from the support handle 2, and the sliding ejector pin 6 is horizontally slidably connected to one end of the chuck 1 near the support handle 2 and extends into the support handle 2.
[0034] like Figure 1 , Figure 2 , Figure 3 As shown, a push rod 61 is provided on the sliding pin 6, which passes through the lower end face of the support handle 2. A spring 62 is sleeved on the sliding pin 6, located in front of the push rod 61. The push rod 61 is located at the front end of the movable handle 4, and is used to flip or push the movable handle 4. A rotating tube 42 for abutting the push rod 61 is rotatably connected to the movable handle 4.
[0035] like Figure 2 , Figure 3 As shown, the bottom ejector pin 7 is vertically threaded to the middle of the chuck 1, and the upper end face of the bottom ejector pin 7 is provided with a support surface in an arc shape.
[0036] like Figure 2 , Figure 3 As shown, the limiting mechanism 8 includes a limiting rod 81, a baffle 82, a fork 83, and a nut 84. The limiting rod 81 vertically penetrates the support handle 2, and a limiting groove 85 is provided on the support handle 2 along its length direction. The baffle 82 is provided on the outer wall of the limiting rod 81 and is used to abut against the lower end face of the support handle 2.
[0037] like Figure 2 , Figure 3 As shown, the fork 83 is located at the lower end of the limiting rod 81 and is used to abut the movable handle 4. The nut 84 is threadedly connected to the limiting rod 81 and is used to press the upper end face of the support handle 2.
[0038] When it is necessary to fix the conduit and the connector sleeve, the connector sleeve is placed on the end of the conduit, and then the connector sleeve is embedded in the chuck 1 so that the connector sleeve abuts against the support surface on the bottom ejector pin 7. Then the bottom ejector pin 7 is rotated to raise and lower, so that the center position of the connector sleeve is aligned with the fixed ejector pin 5 and the sliding ejector pin 6.
[0039] Then, control the rotation of the fixed ejector pin 5 so that it contacts the outer wall of the connector sleeve. Finally, apply pressure to the support handle 2 and the movable handle 4 so that they move closer to each other. At this time, the movable handle 4 drives the rotating tube 42 to move synchronously, and uses the rotating tube 42 to press the push rod 61 to slide horizontally. The push rod 61 drives the sliding ejector pin 6 to slide outward, and cooperates with the fixed ejector pin 5 to press a notch on the connector sleeve, thereby achieving the connection and fixation of the connector sleeve and the conduit.
[0040] Furthermore, when applying pressure to the support handle 2 and the movable handle 4, the nut 84 can be loosened first, and then the limit rod 81 and the fork rod 83 can be pushed to slide horizontally to adjust the position of the fork rod 83. Finally, the nut 84 can be tightened, and the limit rod 81 and the fork rod 83 can be fixed in conjunction with the baffle 82.
[0041] Therefore, when the movable handle 4 is flipped, the fork 83 on the support handle 2 can block the movable handle 4 and limit the flipping angle of the movable handle 4, thereby controlling the extension amount of the sliding ejector pin 6, avoiding uneven force, preventing the conduit joint from being crushed, and thus ensuring molding quality.
[0042] The specific embodiments are merely explanations of this utility model and are not intended to limit it. After reading this specification, those skilled in the art can make modifications to these embodiments without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this utility model.
