Abstract
Description
Technical Field
[0001] This invention belongs to the field of bedding technology, and particularly relates to a quilt fastener. Background Technology
[0002] Comforter fasteners are mainly used to connect comforter covers and comforter inserts to prevent relative displacement during use. They are common household items that enhance the sleep experience. Existing comforter fasteners usually use a lead wire for fixing. For example, Chinese patent application No. 202323155122.1 discloses a comforter fastener, which includes a lead wire that passes through the comforter during use and a movable seat that is detachably connected to the lead wire. The movable seat has an axial direction parallel to the direction in which the lead wire passes through the comforter, and includes a neck arranged along the axial direction for the lead wire to be wound around and a radially protruding head. The head has a thread opening for the lead wire to pass through it.
[0003] In the above technical solution, the thread is wrapped around the neck of the movable seat and then inserted into the thread passage at the head after multiple turns or angles to tighten and hide excess thread. However, in the above technical solution, the effect of fixing the quilt depends entirely on the user's manual knotting skills. That is, after the thread passes through the quilt, it needs to be tied at the insertion end. This process is cumbersome. When it needs to be disassembled and washed, untying and retying are equally time-consuming and laborious, which is even more inconvenient for some users (such as the elderly). In addition, it is easy to wrap the thread too much, resulting in tightness, or wrap it too little, resulting in looseness. It is difficult to accurately control the tightness. As the core connecting component, the thread is prone to aging, hardening, fraying, and even internal fiber breakage, resulting in insufficient long-term durability of the thread and poor performance. Summary of the Invention
[0004] To address the shortcomings of existing technologies, a quilt fastener is provided.
[0005] The present invention is implemented using the following technical solutions:
[0006] A quilt fastener includes an insert and a fixing base. The insert has a rod portion for insertion into the inner side of the fixing base, the end of which is a pointed tip to pierce the quilt. The fixing base has a first hole for the rod portion to enter. The fixing base has a thrust member capable of horizontal displacement or circumferential deflection. The thrust member has an abutment position for abutting against the rod portion. When the rod portion enters the fixing base, the abutment position is located radially on the rod portion and abuts against it to apply a bending moment to the rod portion. The bending moment applied by the thrust member causes a wedging effect between the rod portion and the inner wall of the first hole and between the abutment position, thereby achieving frictional locking and preventing the rod portion from axially retracting.
[0007] After the insertion rod is inserted into the fixing base, it is pressed against the inner wall of the first hole by the force of the pushing component, thereby increasing the friction between the two and forming a friction lock. This prevents the insertion rod from axially retracting. Compared with the existing manual knotting, winding, or tightness adjustment installation methods, this method can eliminate the complicated operation of traditional lead wire knotting, requires no user skills, is plug-and-play, and is easy to operate, improving the convenience of installation / disassembly and the reliability after long-term use.
[0008] Preferably, when the insertion rod is inserted into the fixed seat, the contact point between the thrust member and the insertion rod, the inner axial end wall of the first hole, and the outer axial end wall of the first hole work together to abut against the insertion rod.
[0009] The contact point of the thrust member works together with the inner and outer axial end walls of the first hole to form a constraint force in three directions around the insertion rod, thereby enhancing the reliability of locking and preventing the insertion rod from axially retracting due to accidental pulling.
[0010] Preferably, the inner diameter of the first hole matches the diameter of the insertion rod, thereby increasing the constraint force of the first hole on the insertion rod and further ensuring the locking effect.
[0011] Preferably, a second hole is provided in the fixing seat at a coaxial position with the first hole, the inner diameter of the first hole is greater than or equal to the diameter of the insertion rod; the second hole is a through hole structure or a blind hole structure.
[0012] Preferably, the fixing seat is provided with a plug-in seat, which has a cylindrical structure and its opening forms a second hole. The first hole and the second hole together constitute the insertion channel of the plug-in part. The contact point between the thrust member and the plug-in part is located between the first and second holes and works together to create a wedge effect with the outer surface of the plug-in part. In turn, the plug-in part is prevented from retracting through the joint action of the hole walls of the first and second holes.
[0013] Preferably, the thrust member has a third hole, and the outer surface of the insertion rod is provided with an abutment stop formed by a groove. The first and third holes, or the first, second and third holes together constitute the insertion channel of the insertion rod.
[0014] The grooves create a stop, further increasing the static friction of the insert when it is in a retraction tendency, thereby improving the insert's resistance to accidental pulling.
[0015] The device may have one or more grooves, and multiple grooves can allow the insert to be fitted with bedding of different thicknesses to achieve locking.
[0016] Preferably, the fixed base is further provided with an elastic element, which is used in conjunction with the thrust element.
[0017] When the elastic element is in its normal state, the thrust element is pressed tightly against the insertion rod under the action of the elastic force.
[0018] Preferably, the elastic element is coaxially disposed on the outside of the second hole, one end of the elastic element abuts against the lower side of the thrust element and causes it to swing. The thrust element in the swing state causes the hole wall of the third hole to tilt and abut against the outer surface of the insertion rod to apply force to it.
[0019] The thrust member is in an inclined state under the action of the elastic force. After the insertion rod passes through the first hole, the upper end face of the thrust member forms a guide slope that abuts against the end of the insertion rod. The downward pressure of the insertion rod can make the thrust member overcome the elastic force and move the third hole to a position coaxial with the insertion rod. The first, second and third holes together form the insertion channel of the insertion rod. When the end of the insertion rod passes through the third hole, the thrust member loses the pressure restriction and is pressed against the insertion rod again under the action of the elastic member.
[0020] Preferably, the mounting base includes a first housing and a second housing that are movable relative to each other, the first housing and the second housing being connected by a pivot or a soft material to achieve relative hinge, and the first housing and the second housing being locked when closed.
[0021] The first and second housings can be locked by any existing structure after they are closed. For example, magnetic components can be provided on the contact surfaces of the first and second housings to attract each other with magnetic force to complete the locking, or the locking can be completed by snapping together with a buckle structure.
[0022] Preferably, the first end of the thrust member is restricted after the first housing and the second housing are closed, and a slot is provided on the first housing or the second housing. The slot encloses and forms a button on the first housing or the second housing, and the button abuts against the second end of the thrust member in the oscillating state.
[0023] One approach is to fix the first end of the thrust member by the clamping force after the first and second housings are closed, and to make it undergo elastic deformation by utilizing the physical properties of the material of the thrust member itself, for example, by using a flexible shaft structure at the root of the thrust member; or, by setting a connecting shaft in the width direction of the thrust member, the thrust member can be restricted by utilizing the rotational space formed after the first and second housings are closed.
[0024] By using the button, the thrust component can be pressed and swung to a horizontal position under the action of external force, so that the third hole is collinear with the first and second holes again.
[0025] Compared with the prior art, the beneficial effects of the present invention are:
[0026] By inserting the insert rod into the inside of the fixing seat, an insert-type mechanical locking structure is formed. The force generated by the thrusting component increases the friction between the insert rod and the first, second, and third holes. Through a multi-point coordinated constraint mechanism and a stop-type insert rod, the anti-pull-out stability and long-term reliability of the locked state are ensured. This eliminates the reliance on manual knotting skills and solves the defects of traditional wire-type fasteners, such as cumbersome operation, difficulty in controlling tightness, and easy damage to the wire. This improves the convenience of installation and disassembly and the overall durability. Attached Figure Description

[0035] The present invention will now be further described with reference to the accompanying drawings and specific embodiments.
[0036] Example 1
[0037] like Figure 1 — Figure 5As shown, this embodiment discloses a quilt fastener, including an insert 1 as a sub-connector and a fixing seat 2 as a female connector. The insert 1 includes a cap 12 and a rod 11 extending outward from the cap 12. The end of the rod 11 is a pointed tip 111 to facilitate insertion into and through the quilt.
[0038] The mounting base 2 includes a first housing 51 and a second housing 52 that are movable relative to each other. The two are connected by a flexible connector 50 to form an integral unit. The flexible connector 50 can be formed of any existing flexible material such as silicone or plastic, and is not limited here.
[0039] An arc-shaped buckle 53 is fixedly provided on the outer edge of the first housing 51. An arc-shaped groove 54 for use with the buckle is provided on the inner wall of the second housing 52. After the first housing 51 and the second housing 52 are closed, they are locked by interlocking the built-in arc-shaped buckle 53 and the arc-shaped groove 54. After the first housing 51 and the second housing 52 are closed, a cavity 55 is formed inside.
[0040] The first housing 51 has a first hole 21 for the insertion rod 11 to enter. The inner diameter of the first hole 21 is closely matched with the diameter of the insertion rod 11. The bottom of the second housing 52 is provided with a plug seat 56 at a position coaxial with the first hole 21. The plug seat 56 has a cylindrical structure and its opening forms a second hole 22.
[0041] The outer peripheral surface of the insertion rod portion 11 is provided with a plurality of abutment positions 112 formed by grooves. The abutment positions 112 are arranged along the axial direction of the insertion rod portion 11, and increase the friction between the two after abutting against the thrust member 3.
[0042] The cavity 55 is provided with a thrust member 3 and an elastic member 4 connected to the thrust member 3. The thrust member 3 has a plate-shaped structure, which includes a straight plate part 32 and a connecting shaft 33 extending laterally from the first end of the straight plate part 32 (i.e., the tail position of the straight plate part 32) to both sides. The first housing 51 and the second housing 52 are respectively provided with a pressure plate 57 and a pressure groove 58. When the first housing 51 and the second housing 52 are closed, a space is left between the lower end face of the pressure plate 57 and the bottom of the groove of the pressure groove 58 for placing the connecting shaft 33 of the thrust member 3. The thrust member 3 has a third hole 31 through it. The first hole 21, the second hole 22 and the third hole 31 together constitute the insertion channel of the insertion rod part 11.
[0043] The connecting shaft 33 can be a thinner plate-like structure or a shaft structure. The first end of the connecting shaft 33, as the thrust member 3, can be restricted by the placement space formed between the pressure plate 57 and the pressure groove 58 when the first housing 51 and the second housing 52 are closed, and form a rotation space for its rotation.
[0044] The elastic element 4 is any existing spring used to apply elastic force, such as a thrust spring. The elastic element 4 is wrapped around the outside of the plug seat 56. The elastic element 4 is coaxial with the first hole 21 and the plug part 11. One end of the elastic element 4 acts on the thrust element 3. Under the elastic force of the elastic element 4, the thrust element 3 swings from a horizontal state to an inclined state, thereby maintaining this swing state. In the swing state, the hole wall of the third hole 31 on the thrust element 3 tilts and abuts against the abutment stop 112.
[0045] The first housing 51 and the second housing 52 can be made of any existing plastic material such as POM or reinforced PP. A slot 510 can be opened on the first housing 51, and a button 59 is formed by enclosing the slot 510. Due to the physical characteristics of the first housing 51 itself, the button 59 can undergo elastic deformation. The button 59 abuts against the second end (i.e. the head position of the straight plate 32) in the swing state.
[0046] In the normal state, the first housing 51 and the second housing 52 are in a closed state. The elastic member 4 pushes the straight plate part 32 to an inclined state and makes the second end of the straight plate part 32 abut against the button 59. The third hole 31 is misaligned with the first hole 21 and the second hole 22.
[0047] After the insertion rod 11 is inserted and passes through the bedding, when the tip 111 of the insertion rod 11 passes through the first hole 21, the button 59 is pressed down. The button 59 allows the straight plate 32 to overcome the pushing force of the elastic member 4 and to be in a horizontal position, thereby temporarily moving the third hole 31 to a position coaxial with the first hole 21 and the second hole 22 so that the insertion rod 11 can pass through.
[0048] When the insertion rod 11 is inserted into the second hole 22, the button 59 is released. The thrust member 3 returns to the swing state under the restoring force of the elastic member 4. The inclined third hole 31 wall presses against the abutment stop 112, applying force to achieve friction wedging.
[0049] When disassembly is required, press button 59 to make the thrust member 3 swing back to the horizontal position, release the wedging of the insertion rod 11, and then pull out the insertion rod 11.
[0050] Example 2
[0051] The difference between this embodiment and Embodiment 1 is that: Figure 6As shown, pressure plates 57 are respectively arranged opposite to each other on the first housing 51 and the second housing 52. After the first housing 51 and the second housing 52 are closed, the pressure plates 57 on both sides form a sliding channel for the horizontal displacement of the thrust member 3. The thrust member 3 includes a straight plate part 32, which is horizontally arranged in the cavity 55 and its sliding path is restricted by the sliding channel. The first end of the straight plate part 32 is connected to the elastic member 4, and the second end of the straight plate part 32 abuts against the button 59.
[0052] When the thrust member 3 is in its normal state, the third hole 31 is in a position that is offset from the first hole 21 and the second hole 22.
[0053] After pressing button 59, button 59 pushes the straight plate part 32 to move horizontally and overcomes the force of elastic member 4, thereby moving the third hole 31 to a position coaxial with the first hole 21 and the second hole 22. In this state, the first hole 21, the second hole 22 and the third hole 31 together form the insertion channel of the insertion rod part 11.
[0054] Example 3
[0055] The difference between this embodiment and Embodiment 1 is that: Figure 7 As shown, pressure plates 57 are respectively arranged opposite to each other on the first housing 51 and the second housing 52. After the first housing 51 and the second housing 52 are closed, the pressure plates 57 on both sides press the first end of the thrust member 3.
[0056] The thrust member 3 includes a straight plate portion 32, which has a thin-walled section to form a flexible shaft structure 6. In the normal state, the straight plate portion 32 is in a bent state under the force of the elastic member 4. That is, the straight plate portion 32 is divided into a first part structure α and a second part structure β by the flexible shaft structure 6. The first part structure α and the second part structure β are bent relative to each other. The second part structure β is in an inclined state, and its end is the second end of the thrust member 3, which abuts against the button 59. In this state, the third hole 31 is misaligned with the first hole 21 and the second hole 22.
