When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0037] The hose reel auxiliary device of the present application is installed on the outside of the hose reel bracket, the hose reel includes a hose reel, a coil spring and a bracket, and the device is connected to the gear transmission on the hose reel through a transmission member;

[0038] The object to be wound in the present application is a hose for transmitting gas or liquid, or an electric wire, or a warning tape, etc.

[0039] like Figure 1-3 As shown, the embodiment of the present application provides a hose reel auxiliary device, including a housing 1, the housing 1 is provided with a first groove 11, a first cover 15 is provided at the opening corresponding to the first groove 11, and the first cover 15 is connected to the housing 1;

[0040] A locking mechanism 2, which is disposed inside the first groove 11 and is used to control the locking of the hose reel;

[0041] The transmission member 3 is arranged on a side of the first cover body 15 away from the first groove 11, the transmission member 3 is rotationally connected to the first cover body 15, and the transmission member 3 is transmission-connected to the locking mechanism 2;

[0042] The housing 1, the locking mechanism 2 and the transmission member 3 are coaxially arranged;

[0043] When the transmission member 3 drives the locking mechanism 2 to rotate forward, the locking mechanism 2 locks and unlocks the transmission member 3 in an alternating cycle.

[0044] In this embodiment, an internal thread column 14 is provided on the housing 1, and the first cover 15 is fastened to the internal thread column 14 by a nut;

[0045] The housing 1, the locking mechanism 2, and the transmission member 3 are coaxially arranged. When the object to be wound is pulled outward, the pipe reel rotates forward, and the transmission member 3 is driven to rotate synchronously through the pipe reel gear. The rotation of the transmission member 3 drives the locking mechanism 2 to rotate synchronously. In the process of pulling the object to be wound, the locking mechanism 2 will continuously lock and unlock the transmission member 3, and the operation is repeated in a cycle. After the object to be wound is pulled out to a specified length, if the locking mechanism 2 is locked, the locking mechanism 2 will keep the object to be wound at the pulled-out length, thereby achieving the effect of pulling and stopping at any time when pulling out the object to be wound from the pipe reel and keeping the pulled-out length of the object to be wound. If the locking mechanism 2 is unlocked, the pulled-out object to be wound will be immediately recovered.

[0046] When the winding piece is recovered, the pipe reel rotates in the opposite direction, and the locking mechanism 2 does not perform locking and unlocking operations;

[0047] By setting up the locking mechanism 2, the locking mechanism 2 will continuously perform locking and unlocking operations during the process of releasing the object to be wound from the winding reel, so as to achieve the effect of pulling out the object to be wound from the winding reel and stopping at any time and keeping the pulled-out length of the object to be wound. After pulling out to the specified length, the locking mechanism will perform a locking operation, so that the object to be wound maintains the pulled-out length. There is no need to set up additional structures to limit the object to be wound, the functions are diverse, and the user experience is improved.

[0048] like Figure 4-10 As shown, in one embodiment, the locking mechanism 2 includes a rotating sleeve 21, a locking shaft 22, a torsion spring 23 and a sliding member 24. The rotating sleeve 21 is rotatably arranged in the first groove 11. Two first notches 111 spaced apart are provided on the side wall of the first groove 11. The torsion spring 23 is movably sleeved on the locking shaft 22. A second groove 211 is provided on the rotating sleeve 21. The locking shaft 22 and the torsion spring 23 are rotatably arranged inside the second groove 211. A second notch 212 is respectively provided at the position of the two first notches 111 on the side wall of the rotating sleeve 21. Two ends of the torsion spring 23 respectively pass through the two second notches 212 and extend into the first notch 111 and slide in the first notch 111 and the second notch 212. A sliding groove 13 is provided on the side wall of the first groove 11 along the height direction. The sliding member 24 is arranged in the sliding groove 13 and slides in the sliding groove 13 along the axial direction of the housing 1. The sliding member 24 is connected to the rotating sleeve 21 through a latch assembly, and the sliding member 24 locks and unlocks the latch assembly.

[0049] In this embodiment, when the winding member is pulled out, the tube reel drives the transmission member 3 to rotate forwardly, and the transmission member 3 drives the locking shaft 22 to rotate synchronously, and the locking shaft 22 rotates synchronously and drives the torsion spring 23 to rotate synchronously, so that the torsion spring 23 slides in the first notch 111 and the second notch 212. When the end surface a of one end of the torsion spring 23 contacts the surface e of the corresponding second notch 212, the end surface a is stressed, and the torsion spring 23 will shrink and hold the locking shaft 22. The rotation of the locking shaft 22 drives the torsion spring 23 to rotate, and synchronously drives the rotating sleeve 21 to rotate, and at this time, the latch assembly is also driven to rotate synchronously, and then the latch assembly slides on the sliding member 24 and slides to the rightmost side of the sliding member 24.

[0050] As the locking shaft 22, the torsion spring 23, and the rotating sleeve 21 continue to rotate, when the end surface c of the other end of the torsion spring 23 contacts the surface g of the first notch 111 on one side of the shell 1, the surface c of the torsion spring 23 is stressed, and the torsion spring 23 will loosen and release the locking shaft 22. At this time, the torsion spring 23 and the rotating sleeve 21 stop rotating, but the locking shaft 22 will continue to rotate, and the winding piece can be continuously pulled out from the winding reel. The setting of the first limit block 213 can ensure that the surface f of the second notch 212 on one side of the rotating sleeve 21 and the surface g of the first notch 111 on the corresponding side of the shell 1 maintain a certain distance, so that the torsion spring 23 will not be clamped during the rotation process.

[0051] When the object to be wound is pulled out to the required distance, the pulling of the object to be wound is stopped and the object to be wound is released. At this time, the hose reel rotates counterclockwise under the action of the restoring force to recover the object to be wound, and at this time, the transmission member 3 and the locking shaft 22 are driven to rotate synchronously, and the locking shaft 22 drives the torsion spring 23 to rotate counterclockwise. At this time, the corresponding surface d of the torsion spring 23c surface contacts the surface f. After the d surface is stressed, the torsion spring 23 contracts and holds the locking shaft 22 tightly. The rotation of the locking shaft 22 drives the torsion spring 23 to rotate, and synchronously drives the rotating sleeve 21 to rotate in the opposite direction. At this time, the latch assembly is also driven to rotate synchronously, so that the latch assembly slides to the left on the sliding member 24, and then the latch assembly will be stuck and locked by the sliding block. At this time, the rotating sleeve 21, the torsion spring 23, and the locking shaft 22 all stop rotating, so that the transmission member 3 stops rotating, so that the object to be wound maintains the pulled-out length, thereby achieving the locking effect.

[0052] When unlocking is required, it is only necessary to continue to pull out the winding object, and the rotating sleeve 21 drives the latch assembly to disengage the locking of the sliding member 24;

[0053] During the whole process of pulling the winding object out from the hose reel, the locking and unlocking process is cyclically performed, so that the hose reel can be pulled and stopped at any time and the pulled-out length of the winding object can be maintained;

[0054] After unlocking, when the winding object is to be recovered, the hose reel drives the transmission member 3 to rotate in the opposite direction, drives the locking shaft 22 to rotate synchronously, and the locking shaft 22 drives the torsion spring 23 to rotate counterclockwise. At this time, the d surface of the torsion spring 23 contacts the f surface. After the d surface is stressed, the torsion spring 23 contracts and holds the locking shaft 22 tightly. The rotation of the locking shaft 22 drives the torsion spring 23 to rotate. The rotation of the torsion spring 23 drives the rotating sleeve 21 to rotate synchronously, driving the latch assembly to slide to the leftmost position of the sliding member 24.

[0055] As the locking shaft 22, the torsion spring 23, and the rotating sleeve 21 continue to rotate, the corresponding surface b of the torsion spring 23a surface contacts the surface g of the first notch 111 on the other side of the housing 1, and the surface b of the torsion spring 23 is stressed, while the surface f is not stressed because the latch assembly does not block the leftmost end. At this time, the torsion spring 23 is in a loosened state, and the torsion spring 23 and the rotating sleeve 21 stop rotating, but the locking shaft 22 will continue to rotate in the opposite direction, and the winding member can be continuously recovered into the reel at this time;

[0056] In addition, when the latch assembly slides on the sliding member 24, the sliding member 24 synchronously slides back and forth in the sliding groove 13 to automatically adapt.

[0057] In one embodiment, a first limiting block 213 is disposed on the side wall of the rotating sleeve 21 , and the first limiting block 213 slides in the first notch 111 .

[0058] In this embodiment, the first limit block 213 can ensure that the f surface of the second notch 212 on one side of the rotating sleeve 21 and the g surface of the first notch 111 on the corresponding side of the shell 1 maintain a certain distance, so that the torsion spring 23 will not be clamped during rotation.

[0059] In one embodiment, an annular groove 241 is provided on one side of the sliding member 24 close to the rotating sleeve 21, a third limiting block 242 is provided in the middle of the annular groove 241, a first curved surface 2411, a second curved surface 2412, a third curved surface 2413 and a fourth curved surface 2414 are provided on the bottom surface of the annular groove 241 to form a stepped shape, and a slot 2421 is provided at a position of the third limiting block 242 corresponding to the third curved surface 2413.

[0060] In this embodiment, the first curved surface 2411, the second curved surface 2412, the third curved surface 2413 and the fourth curved surface 2414 are connected end to end to form a ring, and the first curved surface 2411 is higher than the second curved surface 2412 at the connection between the first curved surface 2411 and the second curved surface 2412, the second curved surface 2412 is higher than the third curved surface 2413 at the connection between the second curved surface 2412 and the third curved surface 2413, the third curved surface 2413 is higher than the fourth curved surface 2414 at the connection between the third curved surface 2413 and the fourth curved surface 2414, and the fourth curved surface 2414 is higher than the first curved surface 2411 at the connection between the fourth curved surface 2414 and the first curved surface 2411;

[0061] The latch assembly slides leftward from the first curved surface 2411 until it falls into the second curved surface 2412 near the leftmost end. Due to the height difference, the latch assembly will not return to the first curved surface 2411, but can only slide leftward along the second curved surface 2412 to enter the third curved surface 2413. With such an arrangement, the latch assembly can only slide cyclically along the direction from the first curved surface 2411 to the fourth curved surface 2414 inside the annular groove 241.

[0062] During the sliding process of the latch assembly from the first curved surface 2411 to the fourth curved surface 2414, the rotating sleeve 21 is in a reverse rotation state. When the latch assembly slides from the fourth curved surface 2414 to the first curved surface 2411, the rotating sleeve 21 is in a forward rotation state.

[0063] When the locking operation is performed, the latch assembly enters the slot 2421 from the third curved surface 2413 and is stuck. At this time, the rotating sleeve 21, the torsion spring 23, and the locking shaft 22 all stop rotating, so that the transmission member 3 stops rotating, thereby achieving the locking effect. When the unlocking operation is performed, the latch assembly slides to the left to separate from the slot 2421 and fall into the fourth curved surface 2414. At this time, the latch assembly slides to the right again and enters the starting first curved surface 2411 to complete the unlocking.

[0064] During the whole process of pulling the winding object out from the hose reel, the locking and unlocking process is cyclically performed, so that the hose reel can be pulled and stopped at any time and the pulled-out length of the winding object can be maintained;

[0065] When the object to be wound is to be recovered, the latch assembly slides to the leftmost position of the sliding member 24, and the latch assembly does not slide into the slot 2421. At this time, the rotating sleeve 21 and the torsion spring 23 stop rotating, and the locking shaft 22 and the transmission member 3 continue to rotate, thereby driving the pipe reel to recover the object to be wound.

[0066] In one embodiment, the latch assembly includes a slide rod 214 and an elastic member 215. A hole is opened on the side wall of the rotating sleeve 21. One end of the slide rod 214 is inserted into the hole. The other end of the slide rod 214 always contacts the bottom surface of the annular groove 241 and slides in the annular groove 241. The elastic member 215 is arranged inside the hole and one end is connected to the slide rod 214. The elastic member 215 is used to provide thrust for the slide rod 214 so that the slide rod 214 always keeps contact with the bottom surface of the annular groove 241.

[0067] In this embodiment, the hole opened on the side wall of the rotating sleeve 21 is a blind hole, and the elastic member 215 can make the sliding rod 214 always abut against the bottom surface of the annular groove 241, so that the sliding rod 214 will not be separated from the sliding member 24, thereby avoiding unreliable step transition caused by the gap, resulting in failure of the locking or unlocking switching function;

[0068] Optionally, the hole is a through hole. When the hole on the side wall of the rotating sleeve 21 is a through hole, the latch assembly further includes a bolt 216. At this time, the other end of the spring 215 abuts against the bolt 216, and the bolt 216 is threadedly connected to the inner wall of the through hole. The provision of the bolt 216 can fix the other end of the elastic member 215, provide thrust for the slide bar 214, and the threaded connection facilitates the disassembly and installation of the slide bar 214.

[0069] Optionally, the elastic member is a spring.

[0070] like Figure 11-13 As shown, in one embodiment, the locking shaft 22 and the transmission member 3 are connected via an adjusting assembly, and the adjusting assembly is used to adjust the position state of the sliding rod 214 inside the annular groove 241 .

[0071] In this embodiment, the unlocking or locking of the locking mechanism 2 requires the winding member to be pulled out a certain distance to switch the position state of the slide bar 214 inside the annular groove 241. The purpose of setting the adjustment component is to enable the winding member to be pulled at any time.

[0072] Specifically, when the pulled out piece to be wound is pulled to the bottom and reaches a state where it cannot be pulled anymore, the pulling speed is relatively fast at this time. Due to inertia, the hose reel will still rotate forward an angle. If it is in a locked state at this time, there will be no space for pulling the piece to be wound, and it cannot be unlocked anymore, resulting in the inability to normally recycle the piece to be wound. The transmission member 3 and the locking shaft 22 are designed to be relatively rotatable. Before locking, the transmission member 3 must first be rotated an angle to eliminate the gap. At this time, the hose reel will also retreat an angle accordingly and then be locked. In this way, the situation where it is pulled to the end and locked, and can no longer be pulled or unlocked, resulting in the inability to recycle the piece to be wound will not occur.

[0073] In one embodiment, the adjustment assembly includes a second limit block 221 and a fifth limit block 32. The second limit block 221 is fixedly mounted on one end of the locking shaft 22 close to the transmission member 3. A fourth groove 31 is provided on one side of the transmission member 3 close to the second limit block 221. The second limit block 221 slides in the fourth groove 31. The fifth limit block 32 is provided inside the fourth groove 31.

[0074] In this embodiment, the gear of the hose reel drives the transmission member 3 to rotate, and the rotation of the transmission member 3 drives the fifth limit block 32 to rotate synchronously. At this time, the second limit block 221 will also slide in the fourth groove 31, and the second limit block 221 and the fifth limit block 32 are close to each other. When the second limit block 221 and the fifth limit block 32 are in contact, the second limit block 221 and the fifth limit block 32 are stuck to each other. At this time, the rotation of the transmission member 3 will drive the locking shaft 22 to rotate synchronously;

[0075] With such an arrangement, when there is no space to pull the member to be wound and it is in a locked state, it is only necessary to rotate the transmission member 3 in the opposite direction to drive the fifth limit block 32 away from the second limit block 221. The pipe reel will then retreat an angle accordingly and then be locked. A certain rotation angle is always retained for unlocking to prevent the member from being pulled to the end and locked and unable to be pulled anymore, and unable to be unlocked, resulting in the member to be wound being unable to be recovered.

[0076] In one embodiment, a buffer member 25 is arranged between the transmission member 3 and the locking shaft 22. The buffer member 25 is sleeved in the fourth groove 31. The buffer member 25 includes a third groove 251, a fourth limit block 252 and a third notch 253. The third groove 251 is opened on the side close to the locking shaft 22, the second limit block 221 slides in the fourth groove 31, the fourth limit block 252 is arranged inside the third groove 251, and a third notch 253 is opened on the other side of the buffer member 25 corresponding to the position of the fourth limit block 252. The third notch 253 matches the fifth limit block 32 and the fifth limit block 32 is inserted into the third notch 253.

[0077] In this embodiment, by providing the buffer member 25, the fourth groove 31 and the fifth limit block 32 can be completely wrapped, and when the second limit block 221 slides in the third groove 251 and collides with the fifth limit block 32, buffering can be performed to reduce the impact force, and the second limit block 221 and the fifth limit block 32 can be protected;

[0078] The buffer member 25 is made of nylon.

[0079] The working principle of the hose reel auxiliary device of this application is as follows:

[0080] When the object to be wound is pulled out for the first time, the sliding member 24, the latch assembly, the rotating sleeve 21 and the torsion spring 23 inside the locking mechanism 2 will not restrict the rotation of the locking shaft 22, thereby not restricting the rotation of the hose reel, and the object to be wound can be continuously pulled out;

[0081] When the pipe is pulled out to a specified length, the pipe reel rotates in the opposite direction after the user lets go, and the latch assembly slides into the card slot 2421 and is locked and stuck. At this time, the rotating sleeve 21, the torsion spring 23, the locking shaft 22, and the transmission member 3 all stop rotating, and the pipe reel also stops rotating, so that the pipe to be wound maintains the length pulled out;
