Abstract
Description
Technical Field
[0001] This utility model relates to the field of bedding technology, and more particularly to the field of quilt corner fixing devices, specifically a quilt fixer. Background Technology
[0002] Bedding refers to all kinds of textile products used to cover or pad the bed during sleep and rest. A comforter is a small tool used to fix the comforter core and comforter cover, which can effectively prevent the comforter from shifting, slipping or rolling up, and improve sleep comfort.
[0003] A search revealed that patent application CN202323251496.3 discloses a quilt fastener, including a guide thread and a movable buckle. The movable buckle includes a male and female fastener that cooperate with each other. The male fastener has a through hole for the guide thread to pass through, and the through hole has a relatively narrowed locking part that restricts the relative movement between the guide thread and the male fastener. This application allows the guide thread to directly enter the locking part after passing through the channel, temporarily restricting the relative movement between the male fastener and the guide thread. This keeps the male fastener firmly attached to the object being fastened, greatly facilitating the subsequent installation of the female fastener.
[0004] The locking mechanism of the aforementioned patented quilt fastener is simple and not secure. The front and back covers are fixed by interference fit or simple snap-fit, which makes it easy for the front and back covers to come loose. After the knot is stuck inside the cable slot 113, there is no fixing structure to further restrict the knot, and the knot is at risk of coming out of the cable slot. Therefore, we need to propose a quilt fastener. Utility Model Content
[0005] The purpose of this invention is to provide a quilt fastener. Through the design of the locking mechanism, after the quilt is fixed to the female buckle, the limiting protrusion on the first sleeve passes through the notch on the second sleeve and is pushed into the rotating groove. Then, rotating the male buckle causes the limiting protrusion and the notch to misalign, thus locking the two sleeves radially and securing the male and female buckles, making them less prone to detachment. Through the design of the plunger and the wire-stopping post, after the knot is stuck outside the wire-stopping groove, the plunger is inserted into the wire-stopping post and abuts against the threaded wire, preventing knot displacement and further positioning the knot, reducing the risk of the knot coming out of the wire-stopping groove, thereby solving the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a quilt fastener, comprising a female buckle and a male buckle for threading a guide and clamping the corners of the quilt, and a locking mechanism for fixing the female buckle and the male buckle, wherein the female buckle and the male buckle are coaxially arranged;
[0007] The female buckle includes a first outer shell, with a threading hole at the center of the first outer shell for the threaded wire to pass through, and a blocking part on the inner side of the first outer shell to hold the knot at the end of the threaded wire.
[0008] The male buckle includes a second housing, and a plunger aligned with the blocking portion is connected inside the second housing.
[0009] Preferably, the locking mechanism includes a first sleeve connected to the inside of the female buckle and a second sleeve connected to the inside of the male buckle, wherein the first sleeve is inserted into the inside of the second sleeve.
[0010] Preferably, the upper end of the inner wall of the second sleeve is provided with a plurality of notches arranged in a ring array, and the lower end of the inner wall of the second sleeve is provided with a rotating groove communicating with the plurality of notches, the rotating groove being arranged in a ring.
[0011] Preferably, the upper end of the outer wall of the first sleeve is connected to a plurality of limiting protrusions arranged in a ring array, the limiting protrusions being arranged corresponding to the notch, and the limiting protrusions being slidably arranged inside the rotating slot.
[0012] Preferably, the upper end of the outer wall of the first sleeve is provided with an outer inclined surface, and the upper end of the inner wall of the second sleeve is provided with an inner inclined surface, wherein the slope of the outer inclined surface is the same as the slope of the inner inclined surface.
[0013] Preferably, the blocking part includes a wire-blocking post connected to the inner side of the first housing, the plunger is inserted into the inside of the wire-blocking post, the side wall of the wire-blocking post is provided with a vertically arranged wire-locking groove, and the upper end of the side wall of the wire-locking groove is provided with a rounded chamfer.
[0014] Preferably, a cavity is left between the outer wall of the second sleeve and the inner wall of the second outer shell, and the inner side of the first outer shell covers the cavity.
[0015] Compared with the prior art, the beneficial effects of this utility model are:
[0016] 1. Through the design of the locking mechanism, after the quilt is fixed on the female buckle, the limiting protrusion on the first sleeve passes through the notch on the second sleeve and is pushed into the rotating slot. Then, the male buckle is rotated to make the limiting protrusion and the notch misaligned, thereby locking the two sleeves in the radial direction, realizing the fixation of the male buckle and the female buckle, and the two are not easy to separate.
[0017] 2. This utility model, through the design of a plunger and a wire-stopping post, allows the plunger to be inserted into the inside of the wire-stopping post after the knot is stuck outside the wire-locking groove. The plunger then abuts against the threaded wire, preventing the knot from shifting and further positioning the knot, thus reducing the risk of the knot coming out of the wire-locking groove.

[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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Please see Figure 1-3 This utility model provides a technical solution: a quilt fastener, including a female buckle 10 and a male buckle 20 for threading a guide and clamping the corners of the quilt, and a locking mechanism for fixing the female buckle 10 and the male buckle 20. The female buckle 10 and the male buckle 20 are coaxially arranged; the overall appearance of the female buckle 10 and the male buckle 20 is circular.
[0024] The female buckle 10 includes a first outer shell 11. A threading hole 14 for threading a lead wire is provided at the center of the first outer shell 11. A blocking part is provided on the inner side of the first outer shell 11 to hold the knot at the end of the lead wire. The blocking part can fix the knot inside the female buckle 10.
[0025] The male buckle 20 includes a second outer shell 21. Inside the second outer shell 21, there is a plunger 26 that is aligned with the blocking part. The top side wall of the plunger 26 is provided with a chamfer to facilitate the insertion of the plunger 26 into the interior of the blocking part. This not only serves to fix the corner of the quilt, but also prevents the knot from escaping from the blocking part.
[0026] The locking mechanism includes a first sleeve 12 connected to the inside of the female buckle 10 and a second sleeve 22 connected to the inside of the male buckle 20. The first sleeve 12 is inserted into the inside of the second sleeve 22. The outer diameter of the first sleeve 12 is not greater than the inner diameter of the second sleeve 22.
[0027] The upper end of the inner wall of the second sleeve 22 is provided with multiple notches 24 arranged in a ring array, and the lower end of the inner wall of the second sleeve 22 is provided with a rotating groove 25 that communicates with the multiple notches 24. The rotating groove 25 is arranged in a ring.
[0028] The upper end of the outer wall of the first sleeve 12 is connected to a plurality of limit protrusions 13 arranged in a ring array. The limit protrusions 13 are correspondingly arranged with the notch 24, and the limit protrusions 13 are slidably arranged inside the rotating slot 25.
[0029] The width of the notch 24 is slightly greater than the length of the limiting protrusion 13, and the width of the rotating slot 25 is slightly greater than the width of the limiting protrusion 13.
[0030] After the quilt is fixed on the female buckle 10, install the male buckle 20, insert the first sleeve 12 into the inside of the second sleeve 22, and slide the limiting protrusion 13 down along the notch 24 into the inside of the rotating slot 25, and rotate the male buckle 20 to make the limiting protrusion 13 and the notch 24 misaligned, locking the first sleeve 12 and the second sleeve 22.
[0031] The upper end of the outer wall of the first sleeve 12 is provided with an outer inclined surface 17, and the upper end of the inner wall of the second sleeve 22 is provided with an inner inclined surface 27. The slope of the outer inclined surface 17 is the same as the slope of the inner inclined surface 27.
[0032] The design of the outer bevel 17 and the inner bevel 27 facilitates the insertion of the first sleeve 12 into the interior of the second sleeve 22, reducing the possibility of the first sleeve 12 and the second sleeve 22 colliding.
[0033] The blocking part includes a wire-blocking post 15 connected to the inner side of the first housing 11. A plunger 26 is inserted into the inside of the wire-blocking post 15. A vertically arranged wire-locking groove 16 is provided on the side wall of the wire-blocking post 15. The width of the wire-locking groove 16 is smaller than the size of the knot, which serves to block the knot. The upper end of the side wall of the wire-locking groove 16 is provided with a rounded chamfer. By providing a rounded chamfer on the wire-locking groove 16, it is convenient to pull the knot, guide the lead wire into the inside of the wire-locking groove 16, and lock the knot onto the outer wall of the wire-blocking post 15 through the wire-locking groove 16.
[0034] A cavity 23 is left between the outer wall of the second sleeve 22 and the inner wall of the second outer shell 21. The inner side of the first outer shell 11 covers the cavity 23, which increases the aesthetics of the device.
[0035] It is worth noting that the first outer shell 11, the first sleeve 12, the wire hole 14, the wire stop post 15, the second outer shell 21, the second sleeve 22, and the plunger 26 are arranged coaxially.
[0036] When using, pass one end of the threading wire through the threading needle, then tie the two ends of the threading wire into a knot, and use the threading needle to pass through the quilt (including the quilt core and quilt cover). Then, the threading needle passes through the inside of the thread-blocking post 15 and comes out through the threading hole 14. Pull the knot so that the threading wire passes through the thread-locking groove 16 and the knot is attached to the outer wall of the thread-blocking post 15. That is, the thread-locking groove 16 blocks the knot and prevents the knot from entering the inside of the thread-blocking post 15.
[0037] Then, tie another knot at the end of the threaded wire away from the knot to block the threading hole 14 and secure the quilt. Next, install the male buckle 20, insert the first sleeve 12 into the inside of the second sleeve 22, and slide the limiting protrusion 13 down along the notch 24 into the inside of the rotating slot 25, and insert the plunger 26 into the inside of the thread-blocking post 15. Finally, rotate the male buckle 20 to make the limiting protrusion 13 slide inside the rotating slot 25, that is, to make the limiting protrusion 13 and the notch 24 misaligned, so that the first sleeve 12 cannot come out of the inside of the second sleeve 22, thus securing the male buckle 20 and the female buckle 10. The male buckle 20 also serves to cover the knot, making the device more aesthetically pleasing.
[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
