Description

Technical Field

[0001] The utility model relates to the technical field of wire reels, in particular to a positioning device for a wire reel. Background Art

[0002] The cable winder is also called a hose reel, a cable reel, a reel, or a drum. It is widely used in people's daily life and work. Because of its many functions, it is also called a water drum, an electric drum, or an oil drum. The use of cable winders has made great contributions to the safety of automobile production and the labor-saving of the maintenance industry. Among many automobile maintenance equipment, the cable winder is a special long-distance energy transmission device. Various cable winders can transmit voltage, compressed air, cold water, warm water, engine oil, oxyacetylene, etc. The basic structure of the cable winder is composed of a hose or wire, a rewinding spring, a rotating shaft, and other safety mechanisms.

[0003] However, it was found that the wire reel in the prior art still has some shortcomings during use. Although the rewinding spring setting facilitates the automatic winding and pulling out of the wire reel, it is inconvenient to effectively position and fix the wire reel when one wants to pull out the corresponding length of the connecting wire. Furthermore, under the setting of the rewinding spring, the connecting wire is prone to retraction after being pulled out, which reduces the use effect of the wire reel. Therefore, we propose a positioning device for the wire reel to solve the above problem. Utility Model Content

[0004] The utility model aims to solve the above-mentioned shortcomings and proposes a positioning device for a wire reel.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A positioning device for a wire reel comprises a casing and a connecting wire, an automatic retractable wire reel assembly is arranged between the casing and the connecting wire, and a positioning and fixing assembly for positioning and fixing the automatic retractable wire reel assembly is arranged on the casing.

[0007] Preferably, the automatic retractable winding assembly includes two torsion springs and a rotating shaft rotatably connected to the front and rear inner walls of the casing, the ends of the two torsion springs that are away from each other are respectively fixedly connected to the front and rear inner walls of the casing, a winding roller is provided on the outer fixed sleeve of the rotating shaft, and the connecting wire is wound around the outside of the winding roller.

[0008] Preferably, the outer fixed sleeve of the winding roller is provided with two baffles, the connecting line is located between the two baffles, and the ends of the two torsion springs close to each other are respectively fixedly connected to the corresponding baffles.

[0009] Preferably, the two torsion springs are both sleeved on the outer side of the rotating shaft.

[0010] Preferably, the positioning and fixing assembly includes an external gear ring fixedly connected to the rear side of the baffle plate and an extrusion spring fixedly connected to the top inner wall of the casing, the bottom end of the extrusion spring is fixedly connected to a movable plate, the bottom of the movable plate is fixedly connected to an arc-shaped internal gear, the arc-shaped internal gear is meshed with the external gear ring, and the top of the movable plate is fixedly connected to a pull rod.

[0011] Preferably, a limiting groove is provided on the inner wall of the rear side of the housing, a limiting plate is provided in the sliding sleeve of the limiting groove, and the limiting plate is fixedly connected to the rear side of the movable plate.

[0012] Preferably, the top end of the pull rod extends to the top of the housing and is fixedly connected with a ball, and the extrusion spring is sleeved on the outside of the pull rod.

[0013] Preferably, a guide sleeve is fixedly connected to one side of the housing, and the connecting wire sliding sleeve is arranged in the guide sleeve.

[0014] The present invention relates to a positioning device for a wire reel. When the connecting wire needs to be pulled out for use, the pull rod is first pulled upwards through the ball, and the pull rod drives the movable plate and the arc-shaped inner gear to move upwards and squeeze the squeezing spring. At this time, the arc-shaped inner gear moves upwards and does not abut and mesh with the outer gear ring, and further does not fix the outer gear ring, the baffle plate and the wire winding roller. At this time, the personnel can pull the connecting wire outwards. While pulling the connecting wire, the wire winding roller and the rotating shaft will automatically rotate, and the torsion spring will torsionally store energy. When the length of the pulled connecting wire is sufficient, the ball is released. At this time, under the elastic force of the squeezing spring, the movable plate and the arc-shaped inner gear move downwards and firmly abut against the outer side of the outer gear ring, and further can lock the outer gear ring, the wire winding roller and the rotating shaft, so that the connecting wire will not automatically retract due to the setting of the torsion spring.

[0015] In the utility model, the positioning device of the wire reel, when the use is completed and the connecting wire needs to be retracted, the pull rod and the arc-shaped internal gear are pulled upward according to the above steps, so that the arc-shaped internal gear is not meshed with the outer gear ring. At this time, under the action of the torsion spring, the rotating shaft and the winding roller will automatically rotate in the opposite direction to wind the connecting wire, and then the connecting wire can be automatically retracted onto the winding roller. When the winding is completed, the ball is released. At this time, under the elastic force of the extrusion spring, the arc-shaped internal gear moves downward and abuts against the outer side of the torsion spring on the outer gear ring, so as to fix the winding roller and prevent the rotating shaft from rotating and causing the connecting wire to scatter.

[0016] The utility model has a reasonable structural design. The purpose of automatically retracting the connecting line can be achieved through the setting of the rotating winding roller and the torsion spring. Through the positioning and fixing component, when the length of the pulled-out connecting line is sufficient, the winding roller can be positioned and fixed, so that the connecting line will not automatically retract due to the setting of the torsion spring. At the same time, after the connecting line is wound up, the winding roller can be fixed to avoid the situation where the connecting line is scattered due to the rotation of the rotating shaft, thereby ensuring the neatness of the winding of the connecting line.

An automatic retractable wire reel assembly is arranged between the housing 1 and the connecting line 3. A positioning and fixing assembly for positioning and fixing the automatic retractable wire reel assembly is arranged on the housing 1.

[0024] In the utility model, the automatic retractable wire winding assembly includes two torsion springs 7 and a rotating shaft 5 rotatably connected to the front and rear inner walls of the casing 1.

[0026] Working principle: when it is necessary to pull out the connecting line 3 for use, pull the pull rod 15 upwards, the pull rod 15 drives the moving plate 10 and the arc-shaped inner gear 9 to move upwards and squeeze the squeezing spring 14, at this time, the arc-shaped inner gear 9 moves up and does not abut and mesh with the outer gear ring 8, and then does not fix the outer gear ring 8, the baffle plate 11 and the winding roller 6, at this time, the personnel can pull out the connecting line 3, and while pulling the connecting line 3, the winding roller 6 and the rotating shaft 5 will automatically rotate, and cause the torsion spring 7 to twist and store energy, when the length of the pulled-out connecting line 3 is enough, release the pull rod 15, at this time, under the elastic force of the squeezing spring 14, the moving plate 10 and the arc-shaped inner gear 9 move down and firmly abut against the outside of the outer gear ring 8, and then can be fixed to the outer gear ring 8, the winding roller 6 and the rotating shaft 5, The roller 6 is locked with the rotating shaft 5 so that the connecting line 3 will not automatically retract due to the setting of the torsion spring 7. When the connecting line 3 needs to be retracted, according to the above steps, the pull rod 15 and the arc-shaped internal gear 9 are pulled upward so that the arc-shaped internal gear 9 does not mesh with the outer gear ring 8. At this time, under the action of the torsion spring 7, the rotating shaft 5 and the winding roller 6 will automatically rotate in the opposite direction to wind the connecting line 3, and then the connecting line 3 can be automatically retracted onto the winding roller 6. When the winding is completed, the ball 4 is released. At this time, under the elastic force of the extrusion spring 14, the arc-shaped internal gear 9 moves down and abuts against the outer side of the torsion spring on the outer gear ring 8 to fix the winding roller 6 to prevent the rotating shaft 5 from rotating and causing the connecting line 3 to scatter.

[0029] In the utility model, a guide sleeve 2 is fixedly connected to one side of the housing 1, and the connecting wire 3 is slidably sleeved in the guide sleeve 2, so as to facilitate the guiding of the connecting wire 3 and make its movement more stable.

[0030] When the connecting line 3 needs to be pulled out for use, the pull rod 15 is first pulled upward through the ball 4, and the pull rod 15 drives the movable plate 10 and the arc-shaped inner gear 9 to move upward and squeeze the squeezing spring 14. At this time, the arc-shaped inner gear 9 moves up and does not abut and mesh with the outer gear ring 8, and then does not fix the outer gear ring 8, the baffle plate 11 and the winding roller 6. At this time, the personnel can pull out the connecting line 3. While pulling the connecting line 3, the winding roller 6 and the rotating shaft 5 will automatically rotate, and the torsion spring 7 will twist and store energy. When the length of the pulled-out connecting line 3 is sufficient, the ball 4 is released. At this time, under the elastic force of the squeezing spring 14, the movable plate 10 and the arc-shaped inner gear 9 move down and firmly abut against the outer side of the outer gear ring 8, and then the outer gear ring 8. The winding roller 6 is locked with the rotating shaft 5 so that the connecting line 3 will not automatically retract due to the setting of the torsion spring 7. When the connecting line 3 needs to be retracted after use, pull the pull rod 15 and the arc-shaped internal gear 9 upward according to the above steps so that the arc-shaped internal gear 9 does not mesh with the outer gear ring 8.
