Description

Technical Field

[0001] The utility model belongs to the technical field of pipeline threading, in particular to a threading device for threading indoor pre-buried power pipelines. Background Art

[0002] In the process of daily construction and house decoration, it is necessary to thread the indoor pre-buried power pipes. Indoor pre-buried power pipes generally use PVC pipes. Pre-buried power casing refers to the pre-buried pipes of power lines, communication lines or other lines in the ground when laying on the ground, and then insert the corresponding junction box, connector or socket at the entry or exit of the pipe, and lay waterproof and moisture-proof layers at appropriate locations. Pre-buried power casing is also called pre-buried pipeline, pre-buried drainage pipe, pre-buried water supply pipe, pre-buried sewage pipe, pre-buried gas pipe, pre-buried water pipe, pre-buried heating pipe, pre-buried optical cable pipe, cable, etc.

[0003] When electricians are operating, they need to thread the wires inside the pipes. However, at present, threading the wires inside the pipes is done manually, which is not only inefficient, but also puts a lot of pressure on the hands of electricians when threading the wires. Therefore, it is necessary to design a device to replace manual threading to solve the problem of low efficiency of pipeline threading. Utility Model Content

[0004] The purpose of the utility model is to provide a threading device for indoor pre-buried power pipelines to solve the problems raised in the above background technology. The following technical solution is provided: a threading device for indoor pre-buried power pipelines, comprising:

[0005] A handle-shaped housing, one side of which is provided with a wire insertion hole;

[0006] A clamping assembly is mounted on the upper side of the handle-shaped housing, and the clamping assembly is used to clamp the wire;

[0007] A wire transmission assembly is arranged at one end of the clamping assembly, and is used to transmit the wire clamped at the clamping assembly;

[0008] A positioning component, arranged at the outer ring end of the clamping component, used to drive the clamping component to swing and limit the clamping component;

[0009] The motor switch is arranged at the lower end of the handle-shaped housing and is used to control the start and stop of the wire transmission assembly;

[0010] The main guide block is arranged at the other end of the clamping assembly and is used for guiding the wire.

[0011] In the technical scheme, when the indoor power pre-buried pipeline is threaded, the wire is first inserted from the wire insertion hole, and the wire inserted from the wire insertion hole is passed out from the main guide block through the inside of the clamping component. When the device is used, the positioning component is manually rotated, and the position of the positioning component is moved by the thread transmission. When the positioning component moves, the lower end of the positioning component drives the clamping component to swing, and the clamping component drives the wire transmission component to clamp the upper and lower ends of the wire when it swings; then the motor switch is started, and the motor switch is started to control the wire transmission component to rotate. The wire transmission component rotates and transmits the wire to the end of the main guide block. Because the wire is made of metal, the wire is transmitted under the guidance of the main guide block at this time;

[0012] Finally, hold the bottom end of the handle-shaped shell with your hand, move the main guide block close to the pipe opening of the embedded pipeline, and the wire is transported along the embedded pipe and finally comes out from the opening at the other end, completing the wire threading operation.

[0013] In any of the above technical solutions, further, the clamping assembly includes:

[0014] A cylinder, wherein two through grooves symmetrically arranged in the middle of the cylinder are opened, a swing rod is hingedly arranged inside the cylinder, a transmission groove is arranged at one end surface of the swing rod, a tension spring is arranged at the upper end of the transmission groove, and the other end of the tension spring is fixedly connected to the inner end wall of the cylinder, a paddle is hingedly arranged on the through groove, the upper and lower ends of the paddle are in arc shape, and the lower end of the paddle abuts against the upper end surface of the transmission groove;

[0015] The cable assembly includes:

[0016] The motor is fixedly arranged on one side of the swing rod, and a rubber transmission wheel is arranged at one end of the motor.

[0017] In the present technical solution, the tension spring is always in a stretched state. When the upper end of the paddle is subjected to force and swings, the lower end of the paddle contacts the transmission slot, drives the transmission slot to swing and stretches the tension spring, thereby causing one end of the rubber transmission wheel to contact the wire and clamp the wire. The wire transmission assembly is provided with two upper and lower parts, and the rotation directions of the two rubber transmission wheels are opposite.

[0018] In any of the above technical solutions, further, the positioning component includes:

[0019] An annular buckle shell, wherein an arc transmission groove is fixedly provided inside the annular buckle shell, the cross section of the arc transmission groove is an arc, and the arc transmission groove always abuts against the paddle;

[0020] The positioning component also includes a thread, which is fixedly arranged on the outer ring end surface of the cylinder. An internal thread rotating cylinder is arranged on the thread, and one end of the internal thread rotating cylinder is against the annular buckle shell.

[0021] In the technical solution, thread transmission is provided between the thread and the internal thread cylinder, and the position of the internal thread cylinder is fixed by rotating the internal thread cylinder by hand. When the internal thread cylinder drives the thread to slide along the outside of the cylinder, one end of the arc transmission groove undergoes friction transmission with the paddle, driving the paddle to swing, thereby driving the clamping assembly to swing by rotating the internal thread cylinder. Under the action of the tension of the tension spring, it can ensure that the paddle is always in contact with the through groove.

[0022] In any of the above technical solutions, further, a main guide block is arranged at one end of the cylinder, the interior of the main guide block is conical, and an auxiliary guide block is also arranged inside the cylinder, and the interior of the auxiliary guide block is conical.

[0023] In the technical solution, the interiors of the auxiliary guide block and the main guide block are both tapered, so that the wire can be quickly and accurately inserted between the rubber transmission wheels, completing the fast threading of the wire.

[0024] The beneficial effects of the utility model are as follows: a clamping assembly is provided, and a crank slider mechanism is provided inside the clamping assembly. When the paddle swings, the swing rod is driven to swing through friction transmission, driving one end of the swing rod to approach the wire, and at the same time, a wire transmission assembly is attached to one side of the swing rod. The wire transmission assembly is rotated in opposite directions to drive the wire to move, thereby realizing a quick threading operation, and the clamping assembly is driven to swing by manually rotating the positioning assembly. The threaded transmission has a self-locking property, which can ensure that the clamping position of the clamping assembly on the wire remains stable, thereby ensuring a quick threading operation of the wire.

[0032] Embodiment 1:

[0033] like Figure 1 As shown, this embodiment provides a threading device for threading indoor pre-buried power pipelines, including:

[0034] A handle-shaped housing 10, with a wire insertion hole 11 formed on one side of the handle-shaped housing 10;

[0035] A clamping assembly 20 is mounted on the upper side of the handle-shaped housing 10, and the clamping assembly 20 is used to clamp the wire;

[0036] The wire transmission component 30 is arranged at one end of the clamping component 20, and the wire transmission component 30 is used to transmit the wire clamped at the clamping component 20;

[0037] The positioning assembly 40 is arranged at the outer ring end of the clamping assembly 20, and is used to drive the clamping assembly 20 to swing and limit the swing position of the clamping assembly 20;

[0038] The motor switch 50 is disposed at the lower end of the handle-shaped housing 10 and is used to control the start and stop of the wire transmission assembly 30;

[0039] The main guide block 60 is disposed at the other end of the clamping assembly 20 and is used to guide the wire.

[0040] In the present technical scheme, when the indoor power pre-buried pipeline is threaded, the wire is first inserted from the wire insertion hole 11, and the wire inserted from the wire insertion hole 11 is passed through the inside of the clamping assembly 20 and out from the main guide block 60. When the present device is used, the hand rotates the positioning assembly 40, and the position of the positioning assembly 40 is moved by the thread transmission. When the positioning assembly 40 moves, the lower end of the positioning assembly 40 drives the clamping assembly 20 to swing, and when the clamping assembly 20 swings, it drives the wire transmission assembly 30 to clamp the upper and lower ends of the wire; then the motor switch 50 is started, and after the motor switch 50 is started, the wire transmission assembly 30 is controlled to rotate. When the wire transmission assembly 30 rotates, the wire is transmitted to the end of the main guide block 60. Because the wire is made of metal, the wire is transmitted under the guiding effect of the main guide block 60 at this time;

[0041] Finally, the hand holds the bottom end of the handle-shaped housing 10, and moves the main guide block 60 close to the pipe opening of the pre-buried pipeline. The wire is transported along the pre-buried pipe and finally comes out from the opening at the other end, completing the wire threading operation.

[0044] The wire transmission assembly 30 comprises:

[0045] The motor 31 is fixedly disposed on one side of the swing rod 23 , and a rubber transmission wheel 32 is disposed at one end of the motor 31 .

[0046] In the present technical solution, the tension spring 25 is always in a stretched state. When the upper end of the paddle 26 is subjected to force and the paddle 26 swings, the lower end of the paddle 26 contacts the transmission slot 24, drives the transmission slot 24 to swing and stretch the tension spring 25, thereby causing one end of the rubber transmission wheel 32 to contact the wire and clamp the wire, and the wire transmission assembly 30 is provided with two upper and lower rubber transmission wheels 32, and the rotation directions of the two rubber transmission wheels 32 are opposite.

When the internal thread rotating cylinder 44 drives the thread 43 to slide along the outside of the cylinder 21, one end of the arc transmission groove 42 undergoes friction transmission with the paddle 26, driving the paddle 26 to swing, thereby driving the clamping assembly 20 to swing by rotating the internal thread rotating cylinder 44. Under the action of the tension of the tension spring 25, it can ensure that the paddle 26 is always in contact with the through groove 22.

[0051] In a preferred embodiment of the present invention:
