Description
Technical Field
[0001] The present application relates to the technical field of bobbin yarn dyeing accessories, and in particular to a lock with high sealing performance. Background Art
[0002] The process of bobbin dyeing is to put the bobbin on the porous tube of the yarn rack. During dyeing, the yarn rack is immersed in the dye tank, and the dye liquid flows out of the porous tube and then leaches out from the center of the bobbin to achieve dyeing. In order to improve the leaching effect of the dye liquid and prevent the dye liquid from overflowing from the gap between the bobbin and the porous tube, a sealing lock needs to be installed on the porous tube to seal the end hole of the top bobbin.
[0003] At present, there are many types of locks on the market, but they generally have poor sealing performance. In harsh environments such as humidity and dust, the inside of the lock is easily corroded and damaged, which may cause the lock to loosen during the sealing process of the end hole, causing the lock to fall off from the end hole of the cheese yarn, thereby affecting the normal use and life of the lock and the result of cheese yarn dyeing. Therefore, further improvements can be made. Summary of the invention
[0004] In order to reduce the influence on the final dyeing result of the cheese yarn caused by loosening due to internal damage of the lock, the present application provides a lock with high sealing performance.
[0005] The present application provides a lock with high sealing performance, which adopts the following technical solution:
[0006] A lock with high sealing performance comprises a rotating disk, a sealing ring is coaxially arranged at the bottom of the rotating disk, a pressure ring is coaxially arranged at the bottom of the sealing ring, a ring groove with a thread is through-opened at the axis of the rotating disk, the sealing ring and the pressure ring, the surfaces of the rotating disk, the sealing ring and the pressure ring are covered with a first sealing ring, a first locking piece and a second sealing ring are arranged in the sealing ring, the first locking piece is located on both sides of the ring groove, and the second sealing ring is wound around the ring groove.
[0007] By adopting the above technical scheme, when it is necessary to use a lock to fix the cheese yarn loaded on the yarn frame, after the ring groove of the lock is threadedly connected to the yarn frame, the lock is moved to a suitable position, and then the first locking member is used for auxiliary locking. Since the surfaces of the turntable, the sealing ring and the pressure ring are covered with the first sealing ring, the first sealing ring is used to seal the outside of the lock, and then the second sealing ring located in the sealing ring is used to seal the inside of the lock, thereby increasing the sealing of the inside of the lock, and the first locking member is used for auxiliary locking, thereby realizing the protection and fixation of the lock, and reducing the dyeing result of the cheese yarn caused by the loosening of the lock.
[0008] Optionally, a first buffer member is further provided in the sealing ring and the first buffer member is sleeved in the ring groove.
[0009] By adopting the above technical solution, a first buffer is provided, and the first buffer is utilized to increase the shock-absorbing effect of the ring groove in the sealing ring. When the blocked creel is transferred through the equipment and falls to the ground, the bobbin yarn in the creel may shake, thereby generating an impact force to impact the lock. At this time, the first buffer buffers the ring groove that is threadedly connected to the creel, thereby reducing the occurrence of loosening of the ring groove due to impact.
[0010] Optionally, the first buffer component includes a buffer spring and a limiting sleeve, the buffer spring is sleeved on the outer wall of the annular groove, and the limiting sleeve is sleeved on the outside of the buffer spring.
[0011] By adopting the above technical solution, the limit sleeve can control the compression and release space of the buffer spring to ensure the stability and consistency of the buffer. The buffer spring provides additional elastic force for the ring groove, increases the buffering effect of the ring groove, absorbs more impact energy, and makes the ring groove part in the sealing ring reduce the impact caused by impact or vibration, thereby extending the service life of the buffer.
[0012] Optionally, a locking ring is further provided in the sealing ring, a first sliding groove is provided in the locking ring, the first sliding groove is located on both sides of the ring groove, and the first locking piece can be slidably provided in the first sliding groove.
[0013] By adopting the above technical solution, a first sliding groove is set, and the first locking member can be slidably set in the first sliding groove. The first sliding groove allows the first locking member to move telescopically within a certain range, providing adjustability, ensuring that the first locking member has sufficient space to perform locking operations with the yarn frame.
[0014] Optionally, a second sliding groove is opened in the side wall of the sealing ring, the first locking member can be slidably disposed in the second sliding groove, and the second sliding groove can be connected to the first sliding groove.
[0015] By adopting the above technical solution, a second sliding groove is set, and the first locking member can be slidably set in the first sliding groove. The second sliding groove allows the first locking member to move telescopically within a certain range, providing adjustability, ensuring that the first locking member has sufficient space to perform telescopic operations in the second sliding groove, so that the first locking member can slide and telescope in the first sliding groove.
[0016] Optionally, the first locking member includes a clamping ring, a push rod, and a force plate, the push rod is horizontally inserted into the first sliding groove and the second sliding groove, the clamping ring is installed at the end of the push rod close to the annular groove, the force plate is installed at the end of the push rod away from the annular groove, the sealing ring is provided with a locking bolt, the locking bolt passes through the second sliding groove and is connected to the force plate, the second sliding groove is provided with a first telescopic rod, a first telescopic spring and a second telescopic spring, the first telescopic spring is sleeved on the first telescopic rod, the first telescopic rod is located on both sides of the locking bolt, and the second telescopic spring is sleeved on the push rod.
[0017] By adopting the above technical solution, when locking is required, the locking bolt is tightened by turning, and the locking bolt applies thrust to the force-bearing plate, and the force-bearing plate drives the push rod to move in the first sliding groove and the second sliding groove until the clamping ring contacts the yarn frame and is tightly locked. When unlocking is required, the locking bolt is loosened, and the locking bolt moves outward and separates from the force-bearing plate, and the first telescopic spring and the second telescopic spring on the force-bearing plate are elastically deformed to pull the force-bearing plate back, thereby moving the clamping ring away from the yarn frame.
[0018] Optionally, a third sealing ring is further provided in the sealing ring, and the third sealing ring is located on the top of the locking ring.
[0019] By adopting the above technical solution, a third sealing ring is provided, and the space at the top of the locking ring is sealed, thereby further strengthening the sealing inside the lock head, maintaining the mechanical properties inside the lock head, and ensuring that the functionality and durability of the lock head are protected.
[0020] Optionally, a gripping portion that is recessed inwards is provided on the outer circumference of the turntable.
[0021] By adopting the above technical solution, the inwardly concave gripping portion provides a better gripping point for the turntable, making it easier to manually rotate the turntable and making it more comfortable to hold.

[0023] 1. The first sealing ring is used to seal the outside of the lock head, and the second sealing ring located in the sealing ring is used to seal the inside of the lock head, thereby increasing the sealing inside the lock head, and the first locking member is used for auxiliary locking, thereby realizing the protection and fixation of the lock head, and reducing the dyeing result of the cheese yarn caused by the looseness of the lock head;
[0024] 2. A first buffer is provided to increase the shock-absorbing effect of the ring groove in the sealing ring. When the blocked creel is transferred and landed through the equipment, the cheese yarn in the creel may shake, thereby generating an impact force to impact the lock. At this time, the first buffer buffers the ring groove connected to the creel thread, thereby reducing the loosening of the ring groove due to the impact.
[0025] 3. The inwardly concave gripping portion provides a better gripping point for the turntable, making it easier to manually rotate the turntable and making it more comfortable to hold. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] The surfaces of the turntable 1, the sealing ring 2 and the pressure ring 3 are covered with a first sealing ring 7. The sealing ring 2 is provided with a second sealing ring 8 and a third sealing ring 9. The second sealing ring 8 and the third sealing ring are both wound around the annular groove 4. The second sealing ring 8 is located below the first locking piece 6 and is wound around the annular groove 4. The third sealing ring 9 is located above the first locking piece 6 and is wound around the annular groove 4.
[0035] In actual use, when it is necessary to use a lock to fix the cheese yarn loaded on the yarn frame, after the annular groove 4 of the lock is threadedly connected to the yarn frame, the lock is moved to a suitable position, and then the first locking piece 6 is used for auxiliary locking. Since the surfaces of the turntable 1, the sealing ring 2 and the pressure ring 3 are covered with the first sealing ring 7, the first sealing ring 7 is used to seal the outside of the lock, and then the second sealing ring 8 and the third sealing ring 9 located in the sealing ring 2 are used to seal the inside of the lock, thereby increasing the sealing inside the lock, and the first locking piece 6 is used for auxiliary locking, thereby realizing the protection and fixation of the lock, reducing the dyeing result of the cheese yarn caused by the loosening of the lock.
[0036] refer to Figure 1 , 2 Specifically, in this embodiment, a first buffer member 5 is provided in the sealing ring 2, the first buffer member 5 is located below the first locking member 6, and the first buffer member 5 is sleeved in the ring groove 4;
[0037] The first buffer member 5 includes a buffer spring 51 and a limiting sleeve 52 . The buffer spring 51 is sleeved on the outer wall of the annular groove 4 , and the limiting sleeve 52 is sleeved on the outer side of the buffer spring 51 .
[0038] In actual use, the first buffer 5 is used to increase the shock-absorbing effect of the ring groove 4 in the sealing ring 2. When the locked creel is transferred to the ground through the equipment, the bobbin yarn in the creel may shake after the creel falls to the ground, thereby generating an impact force to impact the lock. At this time, the first buffer 5 buffers the ring groove 4 threadedly connected to the creel to reduce the loosening of the ring groove 4 due to impact. Among them, the limiting sleeve 52 can control the compression and release space of the buffer spring 51 to ensure the stability and consistency of the buffer. The buffer spring 51 provides additional elastic force for the ring groove 4, increases the buffering effect of the ring groove 4, and absorbs more impact energy, so that the ring groove 4 in the sealing ring 2 can reduce the impact caused by impact or vibration, and extend the service life of the buffer.
