Description

Technical Field

[0001] This utility model relates to the field of feather cage technology, specifically a self-locking cage cover. Background Technology

[0002] A loose fiber cage is a device for degumming or dyeing loose fibers (including cotton, cotton slivers, wool, wool tops, viscose fiber, acrylic fiber, polyester fiber, nylon high-elastic bread yarn and hemp fiber) in a single cage. It includes an outer cage, an inner cage, a cage cover and fixing nuts.

[0003] Traditional wool dyeing cages have a separate cover and fixing nut. The fixing nut is fixed, while the cover moves up and down during dyeing. When the cover descends, the fixing nut remains in its original position, causing pressure leakage. Because the cover cannot self-lock when descending, the wool dyeing cage can only perform single-cycle dyeing during dyeing or degumming, meaning the dye liquor flows from the inner cage to the outer cage. Due to the thick yarn layer (distance between the inner and outer cages), this easily leads to differences in color between the inner and outer layers, as well as uneven coloring and grain size. If the dye liquor is circulated in both directions, during the reverse circulation (dye liquor flowing from the outer cage to the inner cage), the removal of impurities in the fiber and the suction of the water pump increase the fiber density, causing the cover to descend while the fixing nut remains in its original position. When the reversing device switches to the forward circulation (dye liquor flowing from the inner cage to the outer cage), the thrust of the water pump causes the cover to move upward, returning to its original position. At this time, the loose fibers lose the pressure of the cage cover, and under the impact of the water flow from the pump, the loose fibers will become loose and cause voids. This causes short circuits in the dye liquor, resulting in differences between the inner and outer layers, color variations, and other consequences. Therefore, traditional loose fiber cage dyeing and degumming can only be carried out in a single cycle.

[0004] To address the aforementioned issues, this invention designs a self-locking cage cover. When the cage cover descends, it self-locks and remains fixed, preventing it from rising. This allows the water flow to circulate in both directions during dyeing or degumming (water flows from the inner cage to the outer cage and from the outer cage to the inner cage), thereby reducing differences between inner and outer layers, color variations, and improving dyeing quality.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0006] The technical problem to be solved by this utility model is to overcome the above-mentioned defects and provide a self-locking cage cover.

[0007] To solve the above-mentioned technical problems, the technical solution provided by this utility model is: a self-locking cage cover, comprising a cage cover body, characterized in that:

[0008] A circular toothed column is located below the cage cover body and is inserted through the cage cover body. The circular toothed column has multiple rings of circular teeth.

[0009] The self-locking device is located at both ends of a circular toothed column. The self-locking device includes a support plate sleeved on the outside of the circular toothed column. Vertical plates are fixedly connected to the top ends of the support plate. A fixed cylinder is fixedly connected to the opposite side of the vertical plates. A slider is slidably connected to the opposite side of the fixed cylinder. A trapezoidal groove is formed in the middle of the opposite side of the slider. A semi-circular locking groove is formed on the opposite side of the slider, and the semi-circular locking groove cooperates with the circular tooth. A guide rod is fixedly connected to the middle of the inner wall of the fixed cylinder. A guide groove is formed on the opposite side of the slider, and the guide rod is slidably connected within the guide groove. A spring is fixedly connected between the inner wall of the fixed cylinder and the slider, and the spring is sleeved on the guide rod.

[0010] A locking plate device is provided at the bottom of the cage cover body. The locking plate device includes a movable plate fixedly connected to the bottom of the cage cover body. Locking plates are fixedly connected to both ends of the bottom of the movable plate, and the locking plates are slidably connected in the trapezoidal groove.

[0011] Furthermore, a guide groove is provided at one end of the inner wall of the trapezoidal slot facing away from each other, and a guide slider is fixedly connected to one end of the bottom of the locking piece. A ball bearing is installed on the guide slider, and the guide slider is slidably connected to the guide groove through the ball bearing.

[0012] Furthermore, the self-locking device is provided with a limiting structure inside. The limiting structure includes limiting grooves opened at both ends of the inner wall of the fixed cylinder. Limiting blocks are fixedly connected to both ends of the slider on the side near the vertical plate. Ball bearings are installed on the limiting blocks. The limiting blocks are slidably connected to the limiting grooves through the ball bearings.

[0013] The advantages of this invention compared to existing technologies are as follows: Through the arrangement of the circular toothed column, self-locking device, and locking plate device, when the cage cover body descends, the slider moves away from the circular toothed column due to its 45°-70° angle. Due to the spring's thrust, the slider moves inward when the cage cover body stops or rises, and then automatically locks the circular toothed column through the engagement of the semi-circular locking groove with the circular toothed column, preventing the cage cover body from rising and thus achieving self-locking. When the process is complete and the cage cover needs to be lifted, the movable plate is raised, and the slider automatically unlocks and leaves the circular toothed column, facilitating the lifting of the cage cover. This allows the cage cover body to self-lock and remain fixed after descent, preventing it from rising and ensuring constant pressure. This allows the water flow to circulate in both directions during dyeing or degumming, reducing differences between inner and outer layers and color variations, thus improving dyeing quality. The self-locking structure is stable, easy to operate, and highly practical. Attached Figure Description

[0021] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses consistent with some aspects of this disclosure as detailed in the appended claims.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0023] like Figures 1 to 6As shown, this embodiment proposes a self-locking cage cover, including a cage cover body 1. A circular toothed post 2 is provided below the cage cover body 1. The circular toothed post 2 is inserted into the cage cover body 1. The circular toothed post 2 is provided with multiple rings of circular teeth 21. The circular teeth 21 are multiple rings and are evenly spaced, and the circular teeth 21 have an oblique angle of 45°-70°.

[0024] The circular toothed column 2 is equipped with self-locking devices 3 at both ends. The self-locking devices 3 include a support plate 31 sleeved on the outside of the circular toothed column 2. Vertical plates 32 are fixedly connected to the top two ends of the support plate 31. A fixed cylinder 33 is fixedly connected to the opposite side of the vertical plate 32. A slider 34 is slidably connected to the opposite side of the fixed cylinder 33. A guide rod 37 is fixedly connected to the middle of the inner wall of the fixed cylinder 33. A guide groove 38 is opened on the opposite side of the slider 34. The guide rod 37 is slidably connected in the guide groove 38. A spring 39 is fixedly connected between the inner wall of the fixed cylinder 33 and the slider 34. The spring 39 is sleeved on the guide rod 37. When the cover body 1 descends, the slider 34 will move away from the circular toothed column due to the 45°-70° angle of the circular toothed column 2. Due to the thrust of the spring 39, the slider 34 will move inward when the cover body 1 stops or rises.

[0025] A trapezoidal slot 35 is provided in the middle of one side of the slider 34, and a semi-circular locking groove 36 is provided on the opposite side of the slider 34. The semi-circular locking groove 36 is used in conjunction with the circular tooth 21. The inner wall shape of the semi-circular locking groove 36 fits the outer wall of the circular tooth 21, so that the inner wall shape of the semi-circular locking groove 36 and the circular tooth 21 can be engaged, thereby automatically locking the circular tooth column 2 and preventing the cover body 1 from rising.

[0026] The bottom of the cage cover body 1 is provided with a locking plate device 4. The locking plate device 4 includes a movable plate 41 fixedly connected to the bottom of the cage cover body 1. Locking plates 42 are fixedly connected to both ends of the bottom of the movable plate 41. The locking plates 42 are slidably connected in the trapezoidal groove 35. The movable plate 41 drives the locking plates 42 to move. At this time, the locking plates 42 slide in the trapezoidal groove 35, thereby pushing the slider 34 to slide in the fixed cylinder 33.

[0027] A guide groove 43 is provided at one end of the inner wall of the trapezoidal slot 35 facing away from each other. A guide slider 44 is fixedly connected to one end of the bottom of the locking piece 42. A ball bearing 45 is installed on the guide slider 44. The guide slider 44 is slidably connected to the guide groove 43 through the ball bearing 45. The arrangement of the guide groove 43, the guide slider 44 and the ball bearing 45 facilitates the limiting and guiding of the movement of the locking piece 42.

[0028] The self-locking device 3 has a limiting structure 5 inside. The limiting structure 5 includes limiting grooves 51 opened at both ends of the inner wall of the fixed cylinder 33. Limiting blocks 52 are fixedly connected to both ends of the slider 34 near the vertical plate 32. Ball bearings 53 are installed on the limiting blocks 52. The limiting blocks 52 are slidably connected to the limiting grooves 51 through the ball bearings 53. The setting of the limiting grooves 51, limiting blocks 52 and ball bearings 53 facilitates the limiting and guiding of the movement of the slider 34.

[0029] In practical application, when the cage cover body 1 descends, the slider 34 moves away from the circular toothed column 2 due to its 45°-70° angle. Due to the thrust of the spring 39, the slider 34 moves inward when the cage cover body 1 stops or rises. This allows it to automatically lock the circular toothed column 2 through the engagement of the semi-circular locking groove 36 with the circular toothed column 21, preventing the cage cover body 1 from rising and achieving self-locking. When the process is complete and the cage cover needs to be lifted, the control plate 41 rises, and the slider 34 automatically unlocks and moves away from the circular toothed column 2, facilitating the lifting of the cage cover. This ensures that the cage cover body 1 can self-lock and remain fixed after descending, preventing it from rising and keeping it constantly pressed down. This allows the water flow to circulate in both directions during dyeing or degumming, reducing differences between inner and outer layers and color variations, thus improving dyeing quality. The self-locking structure is stable, easy to operate, and highly practical.
