[0040] The expansion piece 202 is used for cleaning the inner wall around the through hole 101-1 when the fixing column 201d moves into the through hole 101-1, so as to scrape off the impurities around the through hole 101-1, thereby improving the dredging effect.

[0041] There are four groups of the expansion column 202c and the arc plate 202d, the connecting ring 202e is used for connecting the four expansion columns 202c to ensure that the four expansion columns 202c can move simultaneously, the size of the circular arc formed by the four arc plates 202d is smaller than that of the through hole 101-1 when the arc plates 202d are contracted, and the size of the circular arc is larger than that of the through hole 101-1 when the arc plates 202d are relaxed.

[0043] Embodiment 2

[0044] With reference to Figures 1-10 For the second embodiment of the utility model, the embodiment is based on the previous embodiment.

[0045] Specifically, the connecting ring 202e is fixed on one side of the clamping block 202g, and the expansion column 202c is provided with a clamping groove 202c-1.

[0046] The number of the clamping block 202g and the expansion column 202c is consistent and corresponding, the clamping block 202g is T-shaped, and the clamping groove 202c-1 is correspondingly shaped, by setting a specific shape, the connecting ring 202e cannot hinder the movement of the expansion column 202c, and the four expansion columns 202c can be connected at the same time.

[0047] Specifically, the moving plate 201c is fixed on one side of the second spring 201e, and the other end of the second spring 201e is fixed with the inner wall of the through groove 201b-1.

[0048] The second spring 201e is used for applying a continuous pushing force to the moving plate 201c, so that the moving plate 201c cannot move downward due to its own gravity under the condition that there is no other external force, and the fixed column 201d is attached to the flow guide pipe 101.

[0049] Specifically, one end of the expansion column 202c is inclined, the expansion column 202c is provided with an inclined groove 202c-2, and the squeezing block 202a can be clamped with the inclined groove 202c-2.

[0050] The bottom inclined surface of the expansion column 202c is attached to the inclined surface of the cone 202b, and one end of the extrusion block 202a is correspondingly inclined to the inclined groove 202c-2, when the expansion column 202c moves along the first moving groove 201d-2, the inclined surface of the cone 202b and the inclined surface of the extrusion block 202a extrude the expansion column 202c, so that the expansion column 202c has displacement in the vertical direction while moving horizontally, thereby driving the arc-shaped plate 202d to move away from or close to the fixed column 201d, so as to scrape off the impurities around the inner wall of the through hole 101-1.

[0051] Specifically, the dredging assembly 200 further comprises a fixing piece 203 arranged on one side of the flow guide pipe 101, which comprises a sliding block 203a and a limiting plate 203b, the sliding block 203a is fixed outside the flow guide pipe 101, the rotating plate 201a is provided with a sliding groove 201a-1, the sliding block 203a slides in the sliding groove 201a-1, and the limiting plate 203b is fixed on one side of the flow guide pipe 101.

[0052] The fixing piece 203 is used for connecting the rotating plate 201a and the flow guide pipe 101, the sliding block 203a is T-shaped in cross section, surrounds the outside of the flow guide pipe 101 and is fixed thereto, the sliding groove 201a-1 corresponds in shape to the sliding block 203a, the rotating plate 201a can slide outside the flow guide pipe 101 through cooperation of the sliding block 203a and the sliding groove 201a-1, and the two are not separated, and the number of the limiting plates 203b is two, which are used for limiting rotation of the rotating plate 201a.

[0053] Specifically, the rotating plate 201a is provided with a sliding groove 201a-2, the sliding groove 201a-2 is provided with a locking block 203c, and the sliding block 203a is provided with a locking groove 203a-1, the locking block 203c can be clamped with the locking groove 203a-1.

[0054] One end of the locking block 203c is inclined, the number of the locking grooves 203a-1 is two and they are symmetrically distributed on the sliding block 203a, when the locking block 203c is clamped with the two locking grooves 203a-1, the rotating plate 201a will be located above and below the flow guide pipe 101 respectively, so as to limit the rotating plate 201a and prevent the rotating plate 201a from moving and affecting normal use of the flow guide pipe 101.

[0055] Embodiment 3

[0056] Reference Figures 1-10 For the third embodiment of the utility model, the embodiment is based on the first two embodiments.

[0057] Specifically, one side of the locking block 203c is fixed with a third spring 203d, and the other end of the third spring 203d is clamped with the sliding groove 201a-2.

[0058] The third spring 203d applies a continuous pushing force to the locking block 203c, ensuring that the locking block 203c can be engaged with the locking slot 203a-1, and the locking block 203c has a pull rope 203e fixed at one end, which is used to unlock the rotating plate 201a. Pulling the pull rope 203e compresses the third spring 203d, so that the locking block 203c moves away from the locking slot 203a-1, thereby unlocking the rotating plate 201a.

[0059] Specifically, the arc-shaped plate 202d is provided with a snap ring 202h outside, and the snap ring 202h is fixed with a support plate 202i on one side, and the support plate 202i is fixed with the inner wall of the through slot 201b-1.

[0060] The support plate 202i supports and fixes the snap ring 202h, and the snap ring 202h is used to extrude the arc-shaped plate 202d to limit the movement of the arc-shaped plate 202d, thereby limiting the movement of the expansion column 202c. In the initial state, the four arc-shaped plates 202d are in a contracted state, and the snap ring 202h is located outside the arc-shaped plate 202d. When the push plate 201f is pressed to drive the moving plate 201c to move, the snap ring 202h no longer extrudes the arc-shaped plate 202d. When the fixed column 201d moves into the through hole 101-1, the inner wall of the through hole 101-1 also limits the movement of the arc-shaped plate 202d, under the pulling of the first spring 202f and the cooperation of the extrusion block 202a and the cone 202b, the expansion column 202c moves along the first moving slot 201d-2 to the direction of the connecting ring 202e, and the expansion column 202c moves outward to the fixed column 201d, thereby expanding the arc-shaped plate 202d.

[0061] When the moving plate 201c moves reversely, the inner wall of the through hole 101-1 will hinder the synchronous movement of the arc-shaped plate 202d and the moving plate 201c, thereby making the expansion column 202c move inward to the fixed column 201d, driving the arc-shaped plate 202d to contract, thereby scraping the impurities around the inner wall of the through hole 101-1. When the arc-shaped plate 202d contracts to be smaller than the size of the through hole 101-1, the arc-shaped plate 202d can move with the moving plate 201c, and at the same time the arc-shaped plate 202d will move into the snap ring 202h, thereby limiting the arc-shaped plate 202d again.

[0062] Specifically, the arc-shaped plate 202d is provided with a ring-shaped groove 202d-1 inside, and the ring-shaped groove 202d-1 is provided with a soft cloth 202j.

[0063] The soft cloth 202j has a certain elasticity, and when the arc-shaped plate 202d expands, the soft cloth 202j expands synchronously. There is a soft cloth 202j between adjacent arc-shaped plates 202d, which ensures that the through hole 101-1 is completely covered, thereby scraping the impurities inside.

[0064] Specifically, the main body assembly 100 further comprises a rack 102 and a guide wheel 103, the rack 102 is arranged on one side of the flow guide pipe 101, and the guide wheel 103 is movably connected to one side of the rack 102.

[0065] The guide wheel 103 is used to provide a stable running path for the enameled wire, guide the enameled wire to pass through different coating stations in sequence, and ensure that each part can be accurately coated with lubricating liquid. This is the prior art, and the present scheme will not be described in detail, and those skilled in the art can clearly understand the working principle.

[0066] In use, pulling the pull rope 203e makes the third spring 203d compressed, so that the locking block 203c is away from the locking groove 203a-1, thereby unlocking the rotating plate 201a, then releasing the pull rope 203e, rotating the rotating plate 201a to below the flow guide pipe 101, and making the locking block 203c fit with the locking groove 203a-1 below the sliding block 203a, at this time, the fixed column 201d and the through hole 101-1 are in coaxial position.

[0067] In the initial state, the four arc-shaped plates 202d are in the contracted state, and the clamping ring 202h is located outside the arc-shaped plate 202d. Pressing the push plate 201f drives the moving plate 201c to move, so that the fixed column 201d moves to the inside of the through hole 101-1, and the clamping ring 202h no longer extrudes the arc-shaped plate 202d. When the fixed column 201d moves to the inside of the through hole 101-1, the inner wall of the through hole 101-1 also limits the movement of the arc-shaped plate 202d. Under the pulling of the first spring 202f and the cooperation of the extrusion block 202a and the cone 202b, the expansion column 202c moves along the first moving groove 201d-2 to the direction of the cone 202b, and at the same time, the expansion column 202c moves to the outside of the fixed column 201d, thereby making the arc-shaped plate 202d relax.

[0068] Stop pressing the push plate 201f, and the second spring 201e will push the moving plate 201c back to the initial position. When the moving plate 201c moves reversely, the inner wall of the through hole 101-1 will hinder the synchronous movement of the arc-shaped plate 202d and the moving plate 201c, thereby making the expansion column 202c move along the first moving groove 201d-2 to the direction of the extrusion block 202a, and at the same time, moving to the inside of the fixed column 201d, thereby driving the arc-shaped plate 202d to contract, so as to scrape off the impurities around the inner wall of the through hole 101-1, and complete the dredging work. When the arc-shaped plate 202d contracts to be smaller than the size of the through hole 101-1, the arc-shaped plate 202d can move with the moving plate 201c. When the arc-shaped plate 202d moves to the inside of the clamping ring 202h, the clamping ring 202h will limit the arc-shaped plate 202d again, and return to the initial state.

[0069] Pull the pull rope 203e again, unlock the rotating plate 201a, rotate it to the top of the flow guide pipe 101, and make the locking block 203c fit with the locking groove 203a-1 above the sliding block 203a, so as to avoid the interference of the rotating plate 201a with the coating process.

[0070] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present application and are not limited. Although the present application has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present application can be modified or replaced equivalently without departing from the spirit and scope of the technical solutions of the present application. They should be covered in the scope of the claims of the present application.
