Description

Technical Field

[0001] The utility model relates to a wire-breaking prevention structure for a wire-passing pipe, in particular to a structure capable of preventing the wear of a pull rope of a clamping claw. Background Art

[0002] Nowadays, the selection vending machine moves the gripper to the position of the object by controlling the moving seat to move forward, backward, left, and right, and then raises and lowers the gripper by operating the moving seat to retract or release the pull rope to complete the action of the selection vending machine to grab the object. In its retracting structure, Figure 1 、 Figure 2 As shown, a vertical mounting base 11 is provided on the movable base 10, and a pulley group 12 around which a pull rope 13 is wound is provided on the mounting base 11. An integrally bent extension plate 14 is provided at the bottom edge of the mounting base 11, and a through hole 141 is provided on the extension plate 14. The through hole 141 is provided with a wire tube 15, and the wire tube 15 is provided for the pull rope 13 to pass through the group, so as to position the pull rope 13 for smooth winding and lifting; a through hole 151 is provided through the wire tube 15, and a stop ring 16 is embedded at the bottom end of the wire tube 15. , and a spring 17 is sleeved on the outside of the wire tube 15, and the stop ring 16 is used to stop the bottom edge of the spring 17, and the wire tube 15 is made to pass through the extension plate 14 with its top end from below the through hole 141, and then a C-shaped buckle 18 is buckled on the top end of the wire tube 15, so that the wire tube 15 can be elastically compressed relative to the extension plate 14; the pull rope 13 passes through the through hole 151 and is connected to a clamping claw 19, and the pulley group 12 drives the pull rope 13 in forward and reverse rotation, so that the clamping claw 19 can rise or fall.

[0003] Furthermore, the wire tube 15 is formed of stainless steel in one piece, and the pull rope 13 is woven from PE wire. In the above structure, the pull rope 13 is hard and tough. When the pull rope 13 is released to move the clamping jaw 19 downward, there is no excessive friction between the pull rope 13 and the wire tube 15, which has no effect on the pull rope 13. However, during the game of grabbing objects, when the player operates the clamping jaw 19 to aim at the target to be clamped, the player frequently adjusts the position of the clamping jaw 19 forward, backward, left, and right. At this time, the pull rope 13 will rub against the edge of the through hole 151 at the bottom of the wire tube 15 due to shaking (such as Figure 2 As shown in the figure, due to the high hardness of the stainless steel material of the wire tube 15, the pull rope 13 is worn and then broken; and when the pull rope 13 is reeled in to make the clamping jaw 19 upward, the clamping jaw 19 rises and hits the bottom end of the wire tube 15 and stops. At this time, the clamping jaw 19 is still in a rapid shaking state, which also causes the pull rope 13 to rub against the edge of the through hole 151 at the bottom end of the wire tube 15 and then break. As a result, the manufacturer needs to carry out frequent maintenance, and there is a need for improvement. Utility Model Content

[0015] The present invention will be further described below with reference to the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it. However, the embodiments are not intended to limit the present invention.

[0016] See also Figures 3 to 5 , a wire-passing pipe anti-breaking structure, which includes: a mounting base 21, which is arranged in a movable seat 20 of a selection vending machine, a pulley set 22 is provided on the mounting base 21, and an integrally bent extension plate 23 is provided at the bottom edge of the mounting base 21, and a through hole 231 is provided on the extension plate 23; a wire-passing pipe 24, which is penetrated by a through hole 241, and an external threaded segment 242 is provided at the bottom end of the wire-passing pipe 24; a copper combination cylinder 25, which has an internal threaded hole 251 and a cylinder through hole 252 connected to each other, and the aperture of the internal threaded hole 251 is larger than the aperture of the cylinder through hole 252; and the outer diameter of the copper combination cylinder 25 is larger than the outer diameter of the wire-passing pipe 24, and the external threaded segment 24 of the wire-passing pipe 24 is screwed together with the internal threaded hole 251 of the copper combination cylinder 25 2, so that the through hole 241 is connected with the through hole 252 of the tube, and the copper combination tube 25 is combined with the wire tube 24 into one; a spring 26, which is sleeved on the outside of the wire tube 24 and is stopped at the bottom edge of the spring 26 by the copper combination tube 25, and the wire tube 24 is made to pass through the extension plate 23 with its top end from below the through hole 231, and then a C-shaped buckle 27 is buckled on the top of the wire tube 24, so that the wire tube 24 can be elastically compressed relative to the extension plate 23; and a pull rope 28, one end of which is wound around the pulley group 22 of the mounting base 21, and the other end of which passes through the through hole 241 of the wire tube 24 and the through hole 252 of the tube and is connected to a clamping claw 29, and the pull rope 28 is driven by the pulley group 22 in the forward and reverse directions, so that the clamping claw 29 can be raised or lowered. As described above, the hardness of the copper combination tube 25 is relatively lower than that of stainless steel. Even if the pull rope 28 generates excessive friction with the edge of the tube through hole 252, the pull rope 28 is less likely to wear out. On the contrary, the copper combination tube 25 with lower hardness may be easily pulled and deformed by the pull rope 28, thereby achieving the actual effect of preventing the wire from breaking.

[0017] The composition, function and effect of the above embodiment are described in detail as follows: Figures 3 to 5 As shown, after the pull rope 28 of the present invention passes through the wire tube 24 and the copper combination tube 25, when the player throws the grabbed item to the object taking port by shaking the clamping claw 29, the clamping claw 29 will shake violently at this time; and when the pull rope 28 is wound upward and hits the wire tube 24 to stop winding, the clamping claw 29 is also in a rapid shaking state at this moment; when the clamping claw 29 shakes, there is usually a greater probability of friction between the edge of the tube through hole 252 and the pull rope 28. Since the wire tube 24 is made of stainless steel, the copper combination tube 25 is made of copper and the pull rope 28 is woven with PE wire, the hardness of the copper combination tube 25 is less than the hardness of the wire tube 24. The pull rope 28 contacts and rubs with the copper combination tube 25 with smaller hardness. In this way, the pull rope 28 is less likely to be worn, and relatively speaking, the pull rope 28 can be made more durable and less likely to break, thereby achieving the effect of reducing maintenance costs.

[0018] Furthermore, the outer diameter of the copper combination tube 25 is larger than the outer diameter of the wire tube 24, forming one end that can stop the spring 26. That is to say, the copper combination tube 25 is pressed by the elastic force of the spring 26. In this way, the screwing pressure between the wire tube 24 and the copper combination tube 25 has a greater friction force, thereby preventing the copper combination tube 25 from loosening.

[0019] The above-described embodiments are merely preferred embodiments for the purpose of fully illustrating the present invention, and the scope of protection of the present invention is not limited thereto. Equivalent substitutions or modifications made by those skilled in the art based on the present invention are within the scope of protection of the present invention. The scope of protection of the present invention shall be subject to the claims.
