Description

Technical Field

[0001] This technical solution relates to the field of quilt fastener technology, specifically an easy-to-unlock quilt fastener. Background Technology

[0002] A quilt generally consists of a quilt cover and a quilt insert. The quilt cover is worn over the quilt insert. However, during daily use, the four corners of the quilt insert often shift, leading to air leakage. To solve this problem, quilt fasteners were developed. Quilt fasteners are used to secure the corners of the quilt cover and the quilt insert. They generally consist of a fastener and fastening pins. The fastening pins pass through the quilt cover and the quilt insert and are fixed to the fastener to secure them together.

[0003] Chinese patent CN212878737U discloses a convenient self-unlocking lock cylinder structure. In use, the unlocking button of this lock cylinder is located on one side of the cover, between the cover and the quilt. When the quilt needs to be removed from the quilt cover, the person needs to move the quilt and reach between the cover and the quilt to operate the unlocking button. Since the location of the unlocking button cannot be directly observed, the person needs to search for the unlocking button multiple times, which is also inconvenient and increases the difficulty of use. Summary of the Invention

[0004] The purpose of this technical solution is to provide an easy-to-unlock quilt fastener. By changing the internal structure of the fastener and exposing the unlocking components on the upper shell, the problem of the original fastener being difficult to unlock is solved.

[0005] The purpose of this technical solution is achieved as follows:

[0006] An easy-to-unlock quilt fastener includes: an upper housing; a lower housing for engaging with the upper housing to form a mounting cavity, and the lower housing having a through hole for a locking pin to pass through; a locking body assembly movably disposed within the mounting cavity for engaging with the locking pin to secure the quilt; a locking pin, the end of which passes through the through hole and engages with the locking body assembly; and an unlocking assembly movably disposed on the upper housing and simultaneously abutting against the locking body assembly; wherein, an unlocking part is provided around the through hole of the lower housing, the unlocking part being insertable into the locking body assembly; when locking is required, the end of the locking pin is passed through the through hole and engaged within the locking body assembly, thereby locking the locking pin; when unlocking is required, force is applied to the unlocking assembly to move it, thereby pushing the locking body assembly toward the unlocking part, causing the unlocking part to insert into the locking body assembly, thereby unlocking the locking pin.

[0007] Preferably, the upper housing surface has at least one mounting hole, and the upper housing extends inward at the mounting hole to form a slide rail; the unlocking assembly includes at least one slider, which is movably placed in the slide rail; the front end of the slider is provided with an abutment portion, which movably abuts against the end face of the lock body assembly; when the slider moves toward the lock body assembly, the abutment portion acts on the end face of the lock body assembly, causing the lock body assembly to move toward the locking pin.

[0008] Preferably, the number of mounting holes is set to two, and they are symmetrically opened on the surface of the upper housing; the unlocking component includes two sliders, which are respectively located in corresponding slides; the abutting parts of the two sliders are movable against the end face of the lock body component.

[0009] Preferably, the surface of the upper housing is partially hollowed out, and the unlocking component is disposed in the hollowed-out area; the unlocking component is configured as a lever that can deflect under the action of external force, and the lever moves against the upper end face of the lock body assembly; when the lever is pressed, the lock body assembly moves towards the locking pin.

[0010] Preferably, the paddle is integrally formed on the upper housing via a connecting part.

[0011] Preferably, the connecting part is located on the top surface of the upper housing.

[0012] Preferably, the connecting portion is configured as a U-shaped bent structure located inside the upper housing.

[0013] Preferably, the lower housing has a plurality of baffles formed therein, with gaps between adjacent baffles, and the baffles are arranged around the unlocking part; the baffles can be deflected under the action of external force; the lock body assembly movably abuts against all the baffles.

[0014] Preferably, each of the baffles has a protruding rib, and the lock body assembly movably abuts against the protruding rib.

[0015] The key and beneficial technical effects of this technical solution compared to existing technologies are:

[0016] 1. The unlocking component designed in this technical solution is exposed on the surface of the upper housing. By pressing the unlocking component, the lock body component can be moved to unlock it from the lock pin. The unlocking component is located on the side of the upper housing away from the quilt. When a person needs to unlock, they can directly press the unlocking component on the surface of the upper housing without having to manipulate or change the position of the fastener and the quilt, which simplifies the unlocking process. This unlocking method is simpler and more convenient.

[0017] 2. The unlocking component designed in this technical solution has two structures. The first is a slide rail set inside the upper housing, which can unlock the lock body component by pressing the slider in the middle with two fingers. The second is a lever formed on the surface of the upper housing, which can be tilted, and the lock body component can be unlocked by pressing the lever directly. Both unlocking methods are simple and easy to operate, making it convenient for users to use. Attached Figure Description

[0027] The specific implementation of this technical solution will be further described in detail below with reference to the accompanying drawings.

[0028]

Example 1

[0029] like Figure 1-3As shown, an easy-to-unlock quilt fastener includes an upper housing 1, a lower housing 2, a locking assembly 3, and an unlocking assembly 4. The upper housing 1 and the lower housing 2 are interlocked and installed together. When the two are joined together, the interior is hollow to form an installation cavity. The installation cavity is used to load the locking assembly 3 and the unlocking assembly 4. The locking assembly 3 is movably disposed in the installation cavity and is used to cooperate with the locking pin to fix the quilt. The lower housing 2 has a through hole 11 for the locking pin to pass through. When it is necessary to fix the quilt, the locking pin is inserted from one side of the quilt cover, passes through the cup, extends from the other side of the quilt cover, and then enters the locking assembly 3 through the through hole 11. The two are interlocked to fix the quilt.

[0030] Furthermore, an unlocking part 10 is provided protruding inward from the perforation 11 of the lower housing 2. The unlocking part 10 is configured as a boss and can be inserted into the lock body assembly 3 and move within the lock body assembly 3. In this embodiment, the lock body assembly 3 is set to move in the vertical direction, and the unlocking component 4 is movably disposed on the upper housing 1 and simultaneously abuts against the lock body assembly 3. The unlocking component 4 is configured as a slider 7 and can move horizontally on the upper housing 1. When unlocking is required, force is applied to the unlocking component 4 to move it, thereby pushing the lock body assembly 3 toward the unlocking part 10, so that the unlocking part 10 is inserted into the unlocking component 4, thereby realizing the unlocking of the lock pin.

[0031] Furthermore, when the fastener is installed on the quilt, the upper housing 1 is the housing on the side away from the locking pin, and the slider 7 is exposed on the upper housing 1. In this way, the slider 7 is located on the surface of the upper housing 1, and the personnel can directly observe its position and directly press it to unlock the locking pin.

[0032] Specifically, at least one mounting hole 5 is provided on the surface of the upper housing 1. The upper housing 1 extends inward at the mounting hole 5 to form a slide 6. The slider 7 is movably mounted on the upper housing 1 through the slide 6. The front end of the slider 7 is provided with an inclined abutment part 8. The abutment part 8 is plate-shaped. The lower end face of the abutment part 8 movably abuts against the edge of the upper end face of the lock body assembly 3. Since the abutment part 8 is inclined, when the slider 7 moves horizontally, it will cause the lock body assembly 3 to move downward, thereby moving the lock body assembly 3 towards the lock pin.

[0033] In this embodiment, the number of mounting holes 5 is set to two, and they are symmetrically opened on the surface of the upper housing 1. Therefore, the unlocking component 4 includes two sliders 7, which are respectively located in the corresponding slide rails 6. The abutting parts 8 of the two sliders 7 are movable and abut against the end face of the lock body component 3. When the two sliders 7 are pressed at the same time, the left and right sides of the lock body component 3 are simultaneously subjected to downward force, so that it moves in a balanced manner towards the lock pin, and the unlocking task can be completed more stably.

[0034]

Example 2

[0035] like Figure 4 and Figure 5 As shown, the configuration of this embodiment is largely the same as that of embodiment 1. The only difference is the structure of the unlocking component 4. In this embodiment, the unlocking component 4 is configured as a lever 9 that can deflect under external force. The surface of the upper housing 1 is partially hollowed out, and the lever 9 is located in the hollowed-out area. It is integrally formed with the upper housing 1 through the connecting part 14. The connecting part 14 is configured as at least one part located on the top surface of the upper housing 1. This part is made of the same material as the upper housing 1. In other words, the connecting part 14 is a part formed by hollowing out the upper housing 1. It is itself a part of the upper housing 1. Its purpose is to enable the lever 9 to deflect under force and automatically reset when no force is applied. At the same time, the lower end face of the lever 9 moves against the upper end face of the lock body assembly 3. When the lever 9 is pressed, the lever 9 acts directly on the upper end of the lock body assembly 3, which can make the lock body assembly 3 move towards the lock pin.

[0036]

Example 3

[0037] like Figure 6-8 As shown, the configuration of this embodiment is generally the same as that of embodiment 2. The difference lies in the connection structure between the paddle 9 and the upper housing 1. In this embodiment, the connecting part 14 is configured as a bent structure extending inward along the hollowed-out area. The bent structure can be U-shaped or other shapes. Its purpose is also to enable the paddle 9 to deflect when subjected to force and automatically reset when not subjected to force. In this way, the paddle 9 and the upper housing 1 have only one connection point.

[0038] Furthermore, the lower housing 2 is formed with several baffles 12. All baffles 12 are arranged concentrically around the unlocking part 10, and there is a gap between adjacent baffles 12. In this way, the segmented baffles 12 can be deflected under the action of external force. When the lock body assembly 3 moves downward, the baffles 12 will be deflected outward. The reaction force of the deflection of the baffles 12 will increase the resistance of the lock body assembly 3 moving downward, which can effectively prevent the lock pin from being pulled out by mistake. Each baffle 12 is provided with a protruding rib 13. The lock body assembly 3 moves against the protruding rib 13. The upper end of the protruding rib 13 has an angle. The protruding rib 13 is provided to make the lock body assembly 3 and the through hole 11 concentric when the lock body assembly 3 is assembled. When the lock body assembly 3 is installed, its side wall will be guided by the angle and move along the angle to realize the cooperation between the lock body assembly 3 and the unlocking part 10.

[0039] Furthermore, when the locking pin is inserted into the cover 16, it extends into the lock body 17 and engages with the ball bearing 18. Since the elastic element 19 constantly pushes the ball bearing 18 downward, the ball bearing 18, in accordance with the shape and structure of the lock body 17, will come together to clamp the locking pin, thus clamping the quilt between the locking pin and the retainer. When the unlocking component 4 is pressed, the lock body component 3 can move downward as a whole. In this way, the unlocking part 10 will press against the lock body 17, and the ball bearing 18 will move upward relative to the cover 16, thus moving away from the unlocking pin.
