Description

Technical Field

[0001] The present invention relates to the technical field of pipe winding devices, and in particular to a stop device at any time and its pipe winding device. Background Art

[0002] An automatic pipe winding device uses a flat spiral spring as an energy storage mechanism and the spring as a power source to realize the automatic recovery of the pipeline. When the pipeline is pulled out for operation, the spiral spring stores energy. After the pipeline is released, due to the elastic force of the spiral spring, the reel will rotate to recover the pipeline. In order to keep the pulled pipeline in a fixed position and not be retracted by the reel for convenient operation, the existing pipe winding device uses a ratchet and pawl as a locking structure. The ratchet has a notch. When the pipeline is pulled out, only when the pawl is at the notch of the ratchet, the reel rotates and the pipeline can be recovered. This locking structure requires pulling out the pipeline multiple times to make the pawl correspond to the notch of the ratchet. After the pipeline is pulled out to the required working length, it is necessary to make the pawl snap into the ratchet teeth to prevent the reel from rotating and the pipeline from being recovered. However, there may be a situation where the pawl just corresponds to the notch of the ratchet, and it is necessary to pull down the pipeline for a certain length until the pawl snaps into the teeth, which cannot achieve immediate use and immediate recovery, resulting in low working efficiency and poor user experience. Summary of the Invention

[0003] The purpose of the present invention is to provide a stop device at any time and its pipe winding device. By switching the position of the positioning pin in the stop groove, the locking member drives the lock to lock or release the central gear on the pipe winding device during movement, so that the stop device at any time is in a released and locked state, realizing timely stopping at any time during the use of the pipe winding device, and the stopping function is more accurate and stable, improving the user experience.

[0004] To achieve the above purpose, the technical solution provided by the present invention is: A stop device at any time, including a locking housing, a sliding member movably arranged in the locking housing, a locking member and a lock. A sliding tooth is movably arranged in the sliding member. The locking member is movably connected to the lock. A stop groove is arranged on the locking member. A positioning pin is arranged on the inner side of the locking housing. The sliding member pushes the locking member to move. The locking member drives the lock in a linkage manner. The positioning pin slides along the stop groove to realize the release and locking of the stop device at any time.

[0005] With the above technical solution of the present invention, when the sliding member slides in the locking housing, it pushes the locking member to move. The locking member is movably connected to the locking buckle and drives the locking buckle to act. The locking member pulls the locking buckle so that the locking buckle is swingable relative to the locking member. Through the swinging of the locking buckle, the on-demand stopper is in a released and locked state. During the process of the locking member driving the locking buckle to act, the positioning pin can be movably positioned in the positioning groove. When the action of the locking buckle drives the on-demand stopper to be in a released and locked state, the positioning pin moves to the corresponding position in the positioning groove. Through the mutual cooperation of the sliding member, the locking member, the positioning pin and the locking buckle, the switching between the released and locked states of the on-demand stopper is realized, and its action is reliable, the on-demand function is realized, and the work efficiency is improved.

[0006] For the above on-demand stopper, the sliding member is provided with a guiding hole, the sliding tooth is provided with a positioning rod, and a sliding member spring is arranged between the sliding member and the sliding tooth. The positioning rod passes through the sliding member spring and extends outside the guiding hole. The sliding member spring provides elastic force. During the process of winding and unwinding the pipeline, the sliding tooth meshes with the central gear of the pipe winding device. During the rotation of the on-demand stopper, the sliding tooth meshes with the outer circumference of the central gear and is relatively stationary, so that the locking member contacts and is pushed by the sliding member during the following rotation, so as to drive the locking buckle to loosen the central gear when lowering and recovering the pipeline. After the lowering is completed, the locking member rotates in the reverse direction. When the positioning pin moves to the locking part, the locking buckle fits and clamps with the central gear, and the pipeline can be lowered and stopped at any time. Through the clamping cooperation between the locking buckle and the central gear, the action is reliable and the clamping and locking effect is good.

[0007] For the above on-demand stopper, the locking housing includes an upper cover and a lower cover. The lower cover is provided with a first movable opening and a second movable opening. When the positioning rod corresponds to the first movable opening or the second movable opening, the sliding tooth can axially move out of engagement. The sliding member pushes the locking member to move, so that when the positioning rod moves to the position of the second movable opening, the locking member pulls the locking buckle to loosen the central gear, and the on-demand stopper releases the pipe winding device, and the pipeline can be freely pulled down; when the end of the positioning rod is located in the first movable opening, it is in the state of recovering the pipeline. After the pipeline recovery is completed, the positioning rod resets to the position of the first movable opening.

[0008] For the above on-demand stopper, the inner wall of the upper cover and / or the lower cover is provided with a sliding member groove, and the sliding member moves on the sliding member groove through a sliding block. During the movement of the sliding member, the sliding block can be slidably positioned in the sliding member groove, so that the sliding member moves along the set movement track.

[0009] In the above-mentioned on-demand stopper, a positioning boss is provided in the stop groove. The positioning boss divides the stop groove to form a release portion and a locking portion. When the positioning pin moves to the release portion or the locking portion, the on-demand stopper is in a released state or a locked state correspondingly. During the movement of the locking member, the positioning pin moves in the stop groove. When the positioning pin is located in the release portion of the positioning groove, the on-demand stopper is in a released state; when the positioning pin is located in the locking portion of the positioning groove, the on-demand stopper is in a locked state. The position switching of the positioning pin in the positioning groove corresponds to the release and locking states of the on-demand stopper, serving to switch the working state of the on-demand stopper during the movement of the locking member.

[0010] In the above-mentioned on-demand stopper, a return spring is provided on the lower cover. One end of the return spring abuts against the inner wall of the lower cover, and the other end abuts against the locking member. When the sliding member approaches and pushes the locking member to move, the return spring is compressed. When pulling the pipeline downward, the return spring pushes the locking member to keep it in contact with the locking member. The locking member pulls the lock catch to disengage the lock catch from the central gear of the pipe and wire winder, and the on-demand stopper is in a released state. After the pipeline is recovered, the sliding member returns to the initial position, and the return spring pushes the locking member to move back to its original position.

[0011] In the above-mentioned on-demand stopper, a pin seat and a pin pressing member are provided in the locking housing. The positioning pin is movably arranged on the pin seat, and a pin spring is provided between the pin pressing member and the positioning pin. The pin spring provides elastic force to keep the positioning pin in good fit with the stop groove when the positioning pin moves in the stop groove, maintaining the reliability of the positioning movement of the positioning pin.

[0012] In the above-mentioned on-demand stopper, a sliding groove is provided on the upper cover, and the pin seat can slide on the sliding groove. The positioning pin moves in the stop groove and has a lateral movement trajectory. By sliding the pin seat on the sliding groove, the movement of the positioning pin is stable.

[0013] In the above-mentioned on-demand stopper, a first lock catch groove and a second lock catch groove are provided on the inner wall of the upper cover and / or the lower cover. The lock catch is movably connected to the locking member through a first lock catch pin. The first lock catch pin moves in the first lock catch groove, and a second lock catch pin is provided on the lock catch. The second lock catch pin moves in the second lock catch groove. During the operation of the lock catch to lock or release the central gear on the pipe and wire winder, the first lock catch pin and the second lock catch pin are respectively positioned to move in the first lock catch groove and the second lock catch groove, enabling the lock catch to release or lock the central gear on the pipe and wire winder during the movement driven by the locking member, serving the purpose of releasing or clamping the rotation of the reel and realizing the release direction and locking and stopping rotation of the pipe and wire winder.

[0014] The present invention also provides a pipe and wire winder, including the above-mentioned on-demand stopper.

[0015] The above-mentioned pipe winding device includes a reel, a drum rotatably arranged on the reel, and a spool tightly connected to the drum. A torsion spring is arranged between the reel and the drum. The reel is provided with a central gear. A locking housing is arranged on the drum. A sliding gear is slidably engaged with the central gear and is locked when the locking latch engages with the central gear.

[0016] For the above-mentioned pipe winding device, an inner ring gear is arranged inside the drum. The locking housing is arranged on the reel. The sliding gear is slidably engaged with the inner ring gear and is locked when the locking latch engages with the inner ring gear.

[0017] For the pipe winding device of the present invention, a stop-at-any-time device is arranged on the spool or the reel. The sliding gear of the stop-at-any-time device is engaged with the central gear or the inner ring gear. During the rotation of the spool and the drum, the sliding part can be driven by the central gear or the inner ring gear to move towards the locking part and push the locking part to move. The locking part drives the locking latch to act. Through the cooperation of the locking latch and the central gear or the inner ring gear, when the locking latch engages and clamps the central gear or the inner ring gear, since the locking housing is arranged on the spool, the locking latch clamps the central gear or the inner ring gear, forcing the spool to overcome the winding force of the torsion spring. After pulling down the pipeline to a predetermined length, releasing the hand can prevent the pipeline from being automatically recovered, achieving the purpose of locking at any time.

[0018] The beneficial effects achieved by the present invention are as follows: Through the cooperation of the sliding gear and the central gear or the inner ring gear, the sliding part moves relative to each other inside the locking housing and pushes the locking part to move. Through the linkage of the locking part driving the locking latch inside the locking housing, it is realized that pulling out the pipeline can switch the locking and releasing states of the stop-at-any-time device at any time. When the pipeline is pulled out to the length required for operation and the stop-at-any-time device is in the locked state, the drum does not reverse and the pipeline is not recovered. After the operation is completed, just pull another section of the pipeline, and the stop-at-any-time device can be switched to the released state, the drum reverses, and the pipeline is recovered. Pulling the pipeline again, the stop-at-any-time device is switched to the locked state again. The stop-at-any-time device has the characteristics of locking and releasing at any time compared with the ratchet and pawl structure, effectively improving the working efficiency and the product use experience.

Detailed implementation manners

[0039] The present invention will be further described below in conjunction with the accompanying drawings and the detailed implementation manners.

[0040] As Figures 1 to 7 shown, in conjunction with Figure 10 and Figure 11 , an anytime stopper includes a locking housing 1, a sliding member 2 movably arranged in the locking housing 1, a locking member 3 and a lock 4. The sliding member 2 is movably provided with sliding teeth 21, and the sliding teeth 21 can reciprocate on the sliding member 2. The locking member 3 is movably connected to the lock 4. The locking member 3 is provided with a stopping groove 31. A positioning pin 11 is arranged inside the locking housing 1, and the positioning pin 11 is positioned in the stopping groove 31. The sliding member 2 pushes the locking member 3 to move, the locking member 3 drives the lock 4 in a linkage manner, and the positioning pin 11 slides along the trajectory of the stopping groove 31 to realize the release and locking of the anytime stopper.

[0041] During implementation, the locking housing 1 is arranged on the pipe winding and unwinding device. The sliding teeth 21 are meshed and connected with the central gear 55 on the pipe winding and unwinding device. When pulling down the pipeline, the spool 52 drives the locking housing 1 to rotate. When the sliding teeth 21 are in contact with the central gear 55, the central gear 55 makes the sliding teeth 21 move towards the locking member 3, so that when the locking member 3 rotates following the locking housing 1, it is in contact with the sliding member 2, and the sliding member 2 pushes the locking member 3 to move backward. The stopping groove 31 moves backward, the positioning pin 11 moves relative to the stopping groove 31 and switches positions, and the positioning pin 11 disengages from the initial position. When the sliding member 2 moves backward, it drives the lock 4 to swing, so that the lock 4 releases the central gear 55 with which it is clamped and matched. At this time, the pipeline can be continuously pulled down. When the positioning pin 11 moves to the initial position, the lock 4 clamps the central gear 55, and the anytime stopper is in a locked state, realizing the function of timely stopping after the pipeline is pulled down in place.

[0042] As Figure 2As shown, a positioning boss 32 is provided in the stop groove 31. The positioning boss 32 divides the stop groove 31 to form a release portion 33 and a locking portion 34. When the positioning pin 11 moves to the release portion 33 or the locking portion 34, the ready stop is in a released state or a locked state. When the positioning pin 11 moves to the release portion 33, the locking member 3 drives the lock catch 4 to swing, and the lock catch 4 releases the central gear 55. At this time, the ready stop is in a released state. At this time, through the winding force of the return spring 54, the reel 53 and the winding disc 52 are driven to rotate in the reverse direction, and the pipeline can be freely recovered. When the positioning pin 11 moves to the locking portion 34, the lock catch 4 meshes with and clamps the central gear 55, the ready stop locks the winding disc 52 and the reel 51, and the ready stop is in a locked state, realizing timely stopping of the reel from rewinding the pipeline after pulling down the pipeline and resetting the ready stop after rewinding the pipeline.

[0043] Continue to refer to Figure 2 As shown, at the other end of the stop groove 31 relative to the locking portion 34, a first limiting portion 35 and a second limiting portion 36 are formed. During the process of pulling down the pipeline, when the positioning pin 11 moves to the first limiting portion 35, the lock catch 4 releases the central gear 55, and the pipeline can be freely pulled down. After pulling down the pipeline to a predetermined length, stop pulling down the pipeline and let the pipeline rewind a certain distance. At this time, the positioning pin 11 passes through the release portion 33. Continue to pull down the pipeline to make the positioning pin 11 move to the second limiting portion 36, release the pipeline, and the winding disc 52 and the reel 53 rotate in the reverse direction, driving the locking member 3 to move. When the positioning pin 11 moves from the second limiting portion 36 to the locking portion 34, the ready stop locks, realizing timely stopping after the pulled-down pipeline reaches the position and resetting after rewinding the pipeline.

[0044] As Figure 6 and Figure 7 As shown, a pin seat 12 and a pin pressing member 13 are provided in the locking housing 1. The positioning pin 11 is movably arranged on the pin seat 12, and a pin spring 14 is provided between the pin pressing member 13 and the positioning pin 11. The locking housing 1 includes an upper cover 15 and a lower cover 16. The upper cover 15 is provided with a sliding groove 17, and the pin seat 12 can slide on the sliding groove 17. When the positioning pin 11 switches positions among the release portion 33, the locking portion 34, the first limiting portion 35, and the second limiting portion 36 of the stop groove 31, it has a lateral movement displacement. By sliding the pin seat 12 on the sliding groove 17, the movement of the positioning pin 11 can be made stable. The pin spring 14 provides an elastic force to keep the positioning pin 11 in good contact with the stop groove 31.

[0045] Figure 3 As shown, a return spring 18 is provided on the lower cover 16. One end of the return spring 18 abuts against the inner wall of the lower cover 16, and the other end abuts against the locking member 3. Among them, when the locking member 3 is close to the sliding member 2, the sliding member 2 pushes the locking member 3 to move, and the return spring 18 is compressed. When the sliding member 2 resets and leaves the locking member 3, the locking member 3 is reset by the return spring 18.

[0046] As Figure 4 and Figure 5 shown, the inner walls of the upper cover 15 and / or the lower cover 16 are provided with a first locking groove 191 and a second locking groove 192. The locking latch 4 is movably connected to the locking member 3 through a first locking pin 41. The first locking pin 41 moves within the first locking groove 191. A second locking pin 42 is provided on the locking latch 4, and the second locking pin 42 moves within the second locking groove 192. When the locking member 3 drives the locking latch 4 to act, the first locking pin 41 is inserted into the connecting portion between the locking latch 4 and the locking member 3 and moves within the first locking groove 191. The second locking pin 42 is movably positioned within the second locking groove 192.

[0047] The inner walls of the upper cover 15 and / or the lower cover 16 are provided with a sliding member groove 101. The sliding member 2 moves on the sliding member groove 101 through a sliding block 22. During the pulling down or rewinding of the pipeline, the sliding member 2 can slide on the sliding member groove 101 through the sliding block 22, so that the sliding member 2 moves smoothly when moving between the upper cover 15 and the lower cover 16.

[0048] The sliding member 2 is provided with a guiding hole 25. The sliding tooth 21 is provided with a positioning rod 24. A sliding member spring 23 is provided between the sliding member 2 and the sliding tooth 21. The positioning rod 24 passes through the sliding member spring 23 and extends outside the guiding hole 25. The sliding member spring 23 pushes the sliding tooth 21 to make the sliding tooth 21 fit on the central gear 55. During the rotational movement of the sliding tooth 21 around the outer circumference of the central gear 55, the sliding tooth 21 can reciprocate within the sliding member 2.

[0049] The lower cover 16 is provided with a first movable opening 161 and a second movable opening 162. A positioning rod 24 is provided at the end of the sliding tooth 21. The positioning rod 24 is respectively positioned in the first movable opening 161 and the second movable opening 162, so that the instant stopper is in a locked and released state at any time. Among them, when pulling down the pipeline and rotating the reel 53 and the spool 52, the spool 52 drives the locking housing 1 to rotate, and the sliding member 2 moves closer to the locking member 3 and pushes the locking member 3 to move. The sliding tooth 21 is pushed by the sliding member spring 23 to engage with the central gear 55, and the positioning rod 24 at the end of the sliding tooth 21 disengages from the first movable buckle 161. When pulling down the pipeline causes the reel 53 and the spool 52 to drive the locking housing 1 to rotate, the central gear 55 causes the sliding tooth 21 to move towards the locking member 3. When the positioning rod 24 leaves the first movable opening 161 and is located between the first movable opening 161 and the second movable opening 162, the outer end of the positioning rod 24 abuts against the inner wall of the locking housing 1, and the sliding tooth 21 is pushed to remain engaged with the central gear 55. When the positioning rod 24 on the sliding tooth 21 corresponds to the second movable opening 162, the end of the positioning rod 24 extends into the second movable opening 162. During the continuous rotation process, the central gear 55 can continuously push the sliding tooth 21. Through the action of the sliding member spring 23, the sliding tooth 21 can move continuously back and forth towards the axis direction of the central gear 55. When the positioning pin 11 is located in the release portion 33, due to the action of the sliding member spring 24, the sliding member spring 24 pushes the sliding tooth 21 to fit against the central gear 55, so that the positioning rod 24 leaves the second movable opening 162. The spool 52 can rotate in the reverse direction. At the same time, the locking member 3 is reset by the return spring 18, and the sliding member 2 is pushed to leave the position of the second movable opening 162. When the end of the positioning rod 24 corresponds to the first movable opening 161, during the process of recovering the pipeline, when the tips of the teeth of the sliding tooth 21 and the central gear 55 face each other, the positioning rod 24 is pushed into the first movable opening 161. During the process of recovering the pipeline, the sliding tooth 21 can move continuously back and forth in the sliding member 2.

[0050] As Figure 8 and Figure 9 shown, in combination with Figure 16 and Figure 17 , in another embodiment, the teeth of the sliding tooth 21 and the lock 4 face outward. The sliding tooth 21 fits against the inner ring teeth 56 on the pipe and wire winder. When the lock 4 is clamped with the inner ring teeth 56, the instant stopper locks the pipe and wire winder. Through different meshing and clamping methods, the release and locking of the pipe and wire winder are realized.

[0051] As Figure 10 and Figure 11 shown, a pipe and wire winder includes the instant stopper 1a described in the above specific embodiment.

[0052] In this embodiment, the pipe-winding and wire-winding device includes a reel 51, a drum 53 rotatably arranged on the reel 51, and a spool 52 fixedly connected to the drum 53. A winding spring 54 is provided between the reel 51 and the drum 53. The reel 51 is provided with a central gear 55. A locking housing 1 is arranged on the drum 53. A sliding tooth 21 can be attached to and rotate around the central gear 55, and the locking is achieved when the locking latch 4 meshes with the central gear 55.

[0053] When pulling down the pipeline, the winding spring 54 is compressed, and the winding spring 54 provides the rewinding power to drive the reverse rotation of the drum 53 and the spool 52. When pulling down the pipeline, the drum 53 drives the spool 52 to rotate. The locking housing 1 is arranged on the spool 52, and the locking housing 1 rotates around the axis of the reel 51 following the spool 52. During the rotation, the sliding tooth 21 is attached to and rotates around the central gear 55. The central gear 55 moves the slider 2 towards the locking member 3. The slider 2 pushes the locking member 3 to move, and the locking member 3 drives the locking latch 4 to act. The locking latch 4 releases the central gear 55, and the spool 52 and the drum 53 can rotate freely. After the pipeline is pulled down to a predetermined length, stop pulling down the pipeline, move the positioning pin 11 from the first limiting portion 35 to the release portion 33, and then continue to pull down the pipeline for a certain distance to move the positioning pin 11 from the release portion 33 to the second limiting portion 36. Loosen the pipeline and let it reverse-rotate for a certain distance through the drum 53 and the spool 52, so that the positioning pin 11 moves from the second limiting portion 36 to the locking portion 34. At this time, the locking latch 4 is engaged and clamped with the central gear 55 through the locking member 3, thereby locking the pipe-winding and wire-winding device by the instant stopper and realizing the function of instant stopping after pulling down the pipeline.

[0054] As Figure 16 and Figure 17 shown, in other embodiments, it includes a housing 5. The drum 53 and the spool 52 are arranged in the housing 5. The reel 51 passes through the housing 5, and the drum 53 is rotatable on the reel 51. An inner ring gear 56 is arranged inside the drum 53. The locking housing 1 is arranged on the reel 51. The sliding tooth 21 is in sliding engagement with the inner ring gear 56, and the locking is achieved when the locking latch 4 meshes with the inner ring gear 56. The difference between this embodiment and the above embodiment is that an inner ring gear 56 is arranged inside the drum 53, and the pipe-winding and wire-winding device is locked when the locking latch 4 meshes with the inner ring gear 56. The teeth of the sliding tooth 21 are arranged towards the outside and are attached to the inner ring gear 56.

[0055] As Figure 18 and Figure 19 shown, in other embodiments, the central gear 55 and the locking latch 4 are arranged as a ratchet and pawl matching structure. The pipe-winding and wire-winding device is locked when the pawl is inserted into the notch of the ratchet, and it is in the released state when the pawl disengages from the notch of the ratchet.

[0056] Referring to Figures 10 to 15As shown, the pull-down pipeline, the reel 52 and the drum 53 are driven to rotate by the pull-down of the pipeline. The sliding member 2 pushes the locking member 3 to move, and the locking member 3 drives the lock 4 to act. The lock 4 releases the central gear 55, and the ready stopper is in a released state. During the movement of the locking member 3, the positioning pin 11 moves from the locking portion 34 to the first limiting portion 35, as Figure 13 shown. At this time, the lock 4 releases the central gear 55, and the pipeline can be freely pulled down. After the pipeline is pulled down to the set length, stop pulling down the pipeline. The coil spring 54 drives the drum 53 to rotate in the reverse direction for a certain distance, and the positioning pin 11 moves from the first limiting portion 35 to the release portion 33, as Figure 14 shown. When the positioning pin 11 is located in the release portion 33, the lock 4 releases the central gear 55. At this time, if the pipeline is released, the pipeline can be freely recovered. Continue to pull down the pipeline so that the positioning pin 11 moves from the release portion 33 to the second limiting portion 36, release the pipeline, and the positioning pin 11 will move from the second limiting portion 36 to the locking portion 34, making the ready stopper in a locked state and locking the pipe and wire winder, as Figure 12 shown.

[0057] The position change of the positioning pin 11 in the stopper groove 31 causes the corresponding locking member 3 to move within the locking housing 1. The locking member 3 is movably connected to the lock 4 and drives the lock 4 to act. When the lock 4 is separated from the central gear 55, the pipeline can be continuously pulled down or the pipeline can be released to recover the pipeline.

[0058] The lock 4 is movably connected to the locking member 3 through the first lock pin 41. The first lock pin 41 is positioned in the first lock groove 191. The lock 4 is provided with a second lock pin 42, and the second lock pin 42 is positioned in the second lock groove 192. During the process of the locking member 3 driving the lock 4 to act, the first lock pin 41 and the second lock pin 42 are respectively positioned in the first lock groove 191 and the second lock groove 192, so that when the positioning pin 11 is located at the locking portion 34, the lock 4 clamps the central gear 55, and when the positioning pin 11 leaves the locking portion 34, the lock 4 releases the central gear 55.
