Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present application, "plurality" means at least two, e.g., two, three, etc., unless specifically limited otherwise.

The quilt fixer and the fixing needles are matched to form a quilt fixing device for fixing the quilt core and the quilt cover to limit the displacement of the quilt core and the quilt cover. Wherein the fixed needle can insert in the quilt fixer with a route, and the part of quilt fixer on this route often is the plastics material, if the quilt fixer does not have corresponding spacing to the fixed needle, then there is the fixed needle and is repeating the plug, or violently results in inserting or pierces through corresponding part with exerting oneself, leads to pulling out the difficulty, even the syringe needle exposes outside and then has wounded's potential safety hazard.

Referring to fig. 1 to 9a, the present application provides a quilt fixing device, which includes a needle 100, a needle sheath 200 and a fixing base 300. Wherein the needle body 100 comprises a needle shaft 110 having a first end 101 and a second end 102 and a radially enlarged base 120 provided at the first end 101. The quilt fixing device has first and second ends corresponding to the first and second end portions 101 and 102.

The needle guard 200 has a tip portion 210, which is used to be sleeved on the needle bar 110 for guiding the needle bar 110 to pass through the fixing unit 400, and the fixing unit 400 is generally a quilt and a quilt core, but it is not limited to a quilt and a quilt core, and it can be two fabrics. The fixed seat 300 is provided with a perforation 310 for the second end portion 102 to pass through, the perforation 310 has a blocking position 301 with a reduced diameter, and the needle bar 110 has a retaining portion 130 which crosses the blocking position 301 and has a radial width greater than the aperture of the position. The backstop 130 interacts with the stop 301 to limit the needle shaft 110 from exiting the anchor 300.

The specific using process is as follows: the needle sheath 200 is disposed on the needle shaft 110, and the first end of the needle sheath 200 abuts against the base 120 to provide a limit, so as to ensure that the tip portion 210 extends beyond the second end 102 of the needle shaft 110. The pinch base 120 passes through the fixture 400 through the tip portion 210. The needle sleeve 200 is removed, the through holes 310 of the fixing base 300 are aligned with the needle bar 110 and are mutually closed to finish the assembly, and the needle sleeve and the needle bar are slightly pulled reversely to be away from each other, so that the needle sleeve and the needle bar cannot be separated to prove that the needle sleeve and the needle bar are assembled in place.

The cooperation between fixing base and the needle bar only relies on stopping position realization of backstop portion and perforation self, has saved various cover bodies, lock body isotructure, and then can reduce the volume of fixing base by a wide margin, and is more pleasing to the eye after assembling with the fixture. The sleep is not easily affected.

Referring now to FIG. 8, in one embodiment, the needle shaft 110 has an axial, retaining portion 130 in the form of a radially extending collar 131. For convenience of manufacture, the needle body 100 is made of plastic, and the backstop portion 130 is formed by injection molding. The plastic material can be pressed and deformed by the hole wall of the through hole 310 to pass the blocking position 301 when assembled with the fixing base 300. Moreover, since the needle body 100 is made of plastic, the hardness is not good enough, which is not conducive to penetrating the fixture 400. The needle sheath 200 is made of a plastic material or a metal material having high hardness to assist the needle 100 to pass through the fixing member 400.

Wherein the convex ring 131 is a plurality of convex rings arranged at intervals along the axial direction, which can be adapted to fixtures 400 with different thicknesses, and the fixture 400 is held and clamped by the base 120 and the fixed seat 300.

The male ring 131 is provided with a guide slope 132 at the second end in order to smoothly pass through the through-hole 310. And the perforations 310 are tapered holes with a large outside and a small inside, understood as the perforations 310 decrease in radial dimension from the first end to the second end.

Referring to fig. 7-9 b, in one embodiment, the fixing base 300 is provided with a hole 320 forming a through hole 310, and the retaining portion 130 cooperates with an outer circumference of the hole 320 to limit the needle bar 110 from exiting the through hole 310. A particular outer perimeter may be an end wall 321 of the bore post 320 at the second end;

or the outer periphery (i.e., the blocking position 301) in fig. 7-9 b is the sidewall 326 of the stem 320. In one embodiment, the stem 320 has a base 324 and a head 325, the base 324 is the position where the stem 320 is connected to the holder 300, and the head 325 is opposite to the base 324. The bore post 320 is provided with a slit 322 extending from the head 325 to the base 324 to enable the blocking position 301 to pass through the distracted slot in the backstop 130. The slit 322 is connected to the through hole 310, and as shown in fig. 7, the distance between the two sidewalls of the slit 322 is L1, and L1 is smaller than the radial dimension of the retaining portion 130. The smaller L1 is near the base 324 as the incision 322 is distracted, it being understood that the less the amount of deformation of the incision 322 near the base 324 is.

Referring to fig. 9a and 9b, pushing the needle body 100 causes the retaining portion 130 to protrude from the through hole 310 (i.e., the head 325 of the notch 322), when the needle body 100 is pulled to retract the retaining portion 130, since the outer circumference of the hole pillar 310 is tapered, the notch 322 is equivalent to a channel, the retaining portion 130 acts on the outer tapered surface of the hole pillar 310, and guides the needle shaft 100 into the channel until the retaining portion 130 finally approaches the base 324, in the process, the needle shaft 100 bends. Due to the fact that the deformation capability of the notch 322 at the base 324 is poor and the notch is difficult to be expanded, the needle body 100 can easily cross the blocking position 301 but cannot easily exit the fixed seat 300.

In order to easily push the needle body 100 beyond the blocking position, the notch 322 includes a first notch 322a and a second notch 322b which are oppositely arranged, and the two notches are symmetrically arranged to separate the hole column 320 into two claws 323, so that the deformation of the two claws 323 at the head 325 is facilitated to be away from each other, and the pushing operation is easier. Wherein the first notch 322a is deeper than the second notch 322b, and wherein the retaining portion 130 enters the first notch 322a to ensure the approach to the base portion 324, thereby maintaining the strength of the blocking needle body 100 from withdrawing.

For guiding the needle bar 100 into the first notch 322a, for example, the end of the hole pillar 320 is a slope structure 311 inclined toward the position of the first notch 322a, when the needle body 100 is pulled, the slope structure 311 acts on the retaining portion 130 to slide along the first notch 322a to the base 324 on the outer surface of the hole pillar 320.

The retaining portion 130 is flat at a first end and has a shape matching with the outer peripheral surface of the end wall 321 or the hole pillar 320, so as to limit the separation of the needle body 100 and the fixing base 300. The first end surface of the retaining portion 130 of the present embodiment is a plane, which is convenient for production and manufacturing.

Referring to fig. 10 to 12, in an embodiment, the fixing base 300 is a hollow structure, and the through hole 310 is disposed on a sidewall of the fixing base 300. The hollow structure allows the needle shaft 110 to enter and bend inside thereof, thereby reducing the size of the holder 300 in the axial direction.

The fixing base 300 includes an upper housing 330 and a lower housing 340 fastened to each other, and the through hole 310 is disposed at a center of the lower housing 340. The appearance is succinct, makes things convenient for needle body 100 to aim at the equipment, accords with the operation custom. In one embodiment, an end surface of one of the lower shell 340 and the upper shell 330 on one axial side is provided with a plurality of protrusions 341 circumferentially arranged, and the other is provided with a groove 331 matched with the protrusions 341, and the protrusions 341 are tightly matched with the grooves 331. In fig. 10 and 11, the protrusion 341 is disposed on the lower casing 340, and the recess 331 is disposed on the upper casing 330.

In another embodiment, a protruding ring 342 is protruded radially from the sidewall of one of the lower shell 340 and the upper shell 330 in a circumferential direction, and the other is provided with a locking groove 332 engaged with the protruding ring 342. In fig. 12, the collar 342 is provided with the lower housing 340, and the engaging groove 332 is provided in the upper housing 330. Both the two embodiments are matched through clamping, and the assembly is convenient.

The quilt fixing device of the present application may be configured to cut off the needle bar 110 when removed. Because simple structure, manufacturing cost reduces to do not influence whole change and use.
