Detailed Description

Example 1

According to fig. 1 to 6, the present embodiment provides a quilt fixer, which comprises a main body part 1 integrally formed by plastic through injection molding and having a U shape, and a clamp body part 2 rotatably connected with the main body part and integrally formed by plastic through injection molding.

The main body part comprises a first clamping arm 11 and a second clamping arm 12 which are arranged oppositely, and a connecting part 13 which is integrally connected between one end of the first clamping arm and one end of the second clamping arm; an opening for being stuffed by the quilt edge is formed at one end, far away from the connecting part, between the first clamping arm and the second clamping arm.

The first clamping arm and the second clamping arm are approximately in a parallel state, the connecting part is approximately in an arc shape, or the connecting part is in arc transition with the first clamping arm and the second clamping arm; the opening part can be designed into a horn mouth shape, so that the quilt edge can slide into the range of the main body part.

The clamp body part comprises a deformation part which can generate elastic deformation under the action of external force, a cylinder part 23 connected to one end of the deformation part, and a control part 24 connected to the deformation part and far away from one end of the cylinder part.

The column part is connected with the second clamping arm in a rotating mode at a position close to the connecting part, and a positioning buckle 25 is formed at a position, close to the operating part, of the deformation part.

And a clamp body accommodating hole 14 for the clamp body part to pass through is formed in the second clamping arm, and the inner end surface of the second clamping arm is positioned at the edge of the clamp body accommodating hole and forms a clamp body positioning part 141 matched and positioned with the positioning buckle at the position corresponding to the positioning buckle.

One side shaping of deformation portion orientation first arm lock has clamping end 20, the clamping end with form the clamping interval that is used for pressing from both sides tight different thickness quilt between the first arm lock.

The size of the clamping interval is positively correlated with the size of the elastic deformation generated by the deformation part. That is, when a quilt with a thin thickness is clamped, the clamping area is correspondingly smaller, and the elastic deformation generated by the deformation part is smaller; when a quilt with thicker thickness is clamped, the clamping area is correspondingly larger, and the elastic deformation generated by the deformation part is also larger.

Further, the deformation part comprises a first clamping piece 21 in an arc shape or a bent shape and a second clamping piece 22 in an arc shape or a bent shape, one end of the first clamping piece is integrally connected with the column part, and one end of the second clamping piece is integrally connected with the operation part; the other end of the first clamping piece is connected with the other end of the second clamping piece, the clamping end 20 is positioned at the connecting position of the first clamping piece and the second clamping piece, and the positioning buckle is formed on the side wall of the second clamping piece far away from the connecting part; when the positioning buckle is matched with the positioning part of the clamp body, one ends of the first clamping piece and the second clamping piece, which are close to the clamping end, are bent towards the connecting part; the first clamping piece and the second clamping piece can generate elastic deformation under the action of external force.

The inner wall surface of the first clamping arm is at least provided with an anti-slip tooth 15 at the position opposite to the clamping end.

As shown in fig. 3, the elastic deformation of the first clip piece and the second clip piece can generate downward extrusion force, so that the quilt is clamped between the clamping end and the first clip arm. The elastic deformation of the second clamping piece along the horizontal direction enables the positioning buckle and the positioning part of the clamp body to be switched between a locking state and an unlocking state.

Because the one end that first clamping piece and second clamping piece are close to the exposed core is the form of bending towards connecting portion direction, is located the main part within range and the clamp body portion by the in-process of unblock state downwardly rotating to locking state (location knot with clamp body location portion card), the exposed core can slide towards the left side (shown in figure 3) to promote the quilt edge to a left side, after the fixer is fixed to the quilt like this, the inner wall of connecting portion can laminate with the quilt edge, so not only make the fixer installation pleasing to the eye, do benefit to and avoid fixer and quilt edge to break away from moreover.

The manipulation part is in a button shape with a concave middle part, and when a finger presses the manipulation part, the finger can drive the clamp body part to rotate towards the first clamping arm direction. When the finger is pressed on the operating part and applies force to the connecting part, the second clamping piece can be bent towards the connecting part, so that the positioning buckle is separated from the positioning part of the clamp body.

Furthermore, hinge holes 16 are symmetrically and coaxially formed in the second clamping arm at two sides of the clamp body accommodating hole, and two ends of the column body part are respectively in rotating connection with the hinge holes at two sides; an inlet 161 communicated with the side wall of the hinge hole is formed in the inner wall of the second clamping arm; when the main body part is not acted by external force, the width of the narrowest part of the loading port is smaller than the outer diameter of the column part.

The provision of the loading opening enables the column part to be designed in an injection-molded construction integrally with the clamp body part without the use of additional shaft-like connecting pieces.

Further, when the inner walls of the first clamping arm and the second clamping arm are subjected to opposite external forces, the width of the narrowest part of the loading port can be at least expanded to be equal to the outer diameter of the column part.

Because the main part is the plastics material, itself also has certain elasticity, when installing the main part in the hinge hole, break first arm lock, second arm lock through reverse breaking off with the fingers and thumb and can make the loading mouth open temporarily to great width so that the column body gets into the hinge hole within range. Because the opening of the loading opening faces the inner wall direction of the first clamping arm, when the clamp body is in a use state of clamping a quilt, the stress of the position of the column body faces the direction far away from the loading opening, and the stability of the clamp body cannot be influenced by the loading opening.

Further, the distance between the first clip arm and the second clip arm (i.e. the opening width) is 10-20mm, preferably about 15mm, which is suitable for most of the quilt thickness (the thickness is not the thickness of the quilt in an unstressed state, but the thickness of the quilt in a compressed state when the two sides of the quilt are pressed towards each other). The deformation amplitude of the deformation part enables the effective distance between the clamping areas to be 0-10 mm. When the distance between first arm lock and the second arm lock is about 15mm, the effective distance between centre gripping region is about 5 mm. Generally, the deformation amplitude of the deformation part in the vertical direction (as shown in fig. 3) is not more than half of the width of the opening, so as to avoid plastic deformation or damage of the clamp body part.

Further, a cavity 131 is formed on the outer wall of the connecting part, and a cover body part 3 is arranged on the cavity;

the main body part and the cover body part made of plastic are located in a space surrounded by the concave cavity and the cover body part.

Specifically, in order to ensure the mechanical strength of the main body part, or in order to ensure that the main body part does not deform or does not excessively deform in a use state, the connecting part needs to have better torsion resistance, so the thickness of the connecting part needs to be larger, but the connecting part is not beneficial to heat dissipation during injection molding if the thickness of the connecting part is too large, and injection molding defects are easily generated, so that the outer wall of the connecting part is provided with the cavity, so that the outer wall of the connecting part is positioned at two sides of the cavity to form a form of two reinforcing ribs, and the requirements of the mechanical strength and the torsion resistance of the connecting part are met, and the requirements of an injection molding process are also met. In addition, lid body portion is used for hiding on the one hand the cavity makes the main part surface level and smooth pleasing to the eye, and the sprue when making main part and lid body portion injection moulding on the one hand all hides in the cavity within range for the fixer surface does not have the sprue and produces the burr, avoids producing the damage to quilt or clothing.

Further, a first clamping portion 132 is formed in the position, close to the second clamping arm, in the cavity, and a second clamping portion 134 is formed in the position, close to the first clamping arm, in the cavity; the cover body part comprises a cover body 31 with elasticity, a first buckle 32 formed on the inner wall of one end of the cover body and a second buckle 33 formed on the inner wall of the other end of the cover body; the first buckle is fixedly clamped with the first clamping part, and the second buckle is fixedly clamped with the second clamping part; and the side wall of the second buckle is formed into a guide inclined surface 331 which is beneficial for the second buckle to slide to the clamping position relative to the second clamping part.

During installation, first buckle 32 is aligned to first clamping portion 132 and is installed in place, and guide inclined plane 331 of second buckle just supports on second clamping portion 134, and only need exert thrust in lid outer wall toward main body portion direction, can make the guide inclined plane slide along second clamping portion, and last second buckle promptly with second clamping portion block.

More than one cover body supporting part 133 is formed in the concave cavity, the cover body supporting parts are abutted to or close to the inner wall of the cover body, and the injection port of the main body part is formed in the end face, facing the cover body part, of the cover body supporting part, different from the cover body supporting part.

The lid supporting part makes lid portion can not produce bending deformation when receiving external force to press to avoid the first buckle or the second buckle and the first joint portion or the second joint portion of lid portion to throw off. Meanwhile, the cover body supporting part protrudes out of the inner wall of the concave cavity, and the injection port is arranged on the cover body supporting part, so that the excess plastic scraps at the position of the injection port can be removed conveniently.

When the clamp is used, the finger is pressed on the operating part and is shifted towards the direction far away from the positioning part of the clamp body, so that the positioning buckle is separated from the positioning part of the clamp body, then the clamp body part is rotated to enable the clamping end to be far away from the first clamping arm, and the clamping end is preferably rotated to the state shown in the upper drawing of figure 3. Then the edge of the quilt is stuffed into the opening of the main body part, preferably the edge of the quilt is tightly attached to the inner wall of the connecting part, then fingers are pressed on the operating part and push the clamping body part towards the direction of the first clamping arm, so that the clamping end is propped against the quilt, the operating part is continuously pushed until the positioning buckle is clamped with the positioning part of the clamping body, and in the process, the first clamping piece and the second clamping piece generate elastic deformation, so that the quilt is clamped between the clamping end and the inner wall of the first clamping arm.
