Detailed Description

Reference will now be made in detail to embodiments of the present utility model, examples of which are illustrated in the accompanying drawings. The embodiments described below by referring to the drawings are illustrative and intended to explain the present utility model and should not be construed as limiting the utility model.

As shown in fig. 1 to 3, a fixing frame 100 according to an embodiment of the present utility model includes a central portion 1, a first buckling portion 2 and a second buckling portion 3. Wherein the central portion 1, the first buckling portion 2 and the second buckling portion 3 can be integrally formed, the material of the fixing frame 100 can be plastic, and the fixing frame 100 can be formed by injection molding.

The central portion 1 may be annular, and the first buckling portion 2 and the second buckling portion 3 may be oppositely arranged in a left-right direction, where the first buckling portion 2 may be integrally formed on a left side of the central portion 1, and the second buckling portion 3 may be integrally formed on a right side of the central portion 1. In use, as shown in fig. 8, the first buckling portion 2 and the second buckling portion 3 can be respectively engaged and matched in the corresponding buckling grooves 63, so that the assembly locking of the fixing frame 100 can be realized.

As shown in fig. 2, the first buckling portion 2 and the second buckling portion 3 may have a generally C-shaped structure, wherein a first cavity 21 is defined between the first buckling portion 2 and the central portion 1, and a second cavity 31 is defined between the second buckling portion 3 and the central portion 1.

When the fixing frame 100 is assembled, the fixing frame 100 can be pressed downwards along the axial direction (up-down direction) of the fixing frame 100, at this time, the first buckling position part 2 and the second buckling position part 3 can be extruded and deformed inwards, the first cavity 21 can provide a deformation space for the first buckling position part 2, the second cavity 31 can provide a deformation space for the second buckling position part 3, so that the length dimension (the dimension in the left-right direction) of the fixing frame 100 is adjustable, namely, the length dimension of the fixing frame 100 can be adaptively reduced when the fixing frame 100 is extruded in the left-right direction, and the first buckling position part 2 and the second buckling position part 3 are conveniently clamped and matched in two buckling position grooves 63 which are oppositely arranged.

The fixing frame may be deformed by pressing to release the locking of the fixing frame 100 by the deformation of the fixing frame. For example, as shown in fig. 7, an inner hole 101 may be formed in the central portion 1, when the locking of the fixing frame 100 needs to be released, the central portion 1 may be pressed inward, and the deformed central portion 1 may drive the first buckling portion 2 and the second buckling portion 3 to move inward, so that the first buckling portion 2 and the second buckling portion 3 may be removed from the corresponding buckling grooves 63.

In the assembly of the fixing frame 100 according to the embodiment of the utility model, the first buckling part 2 and the second buckling part 3 of the fixing frame 100 can be respectively clamped and matched in the corresponding buckling grooves 63, and the fixing frame 100 is difficult to be separated from the buckling grooves 63 due to the limiting acting force in the vertical direction under the action of no external force, so that the blocking and fixing effects of the fixing frame 100 on the blade 300 are ensured.

In the process of installing the fixing frame 100, the length and the size of the fixing frame 100 can be adaptively adjusted under the action of the first cavity 21 and the second cavity 31, so that the fixing frame 100 is convenient to install; when the locking is required to be released, the central part 1 is manually extruded, so that the fixing frame 100 is convenient to disassemble, and convenience is brought to users.

For example, as shown in fig. 2, the first buckling portion 2 and the second buckling portion 3 may be identical in shape, and the first buckling portion 2 and the second buckling portion 3 may be mirror-symmetrically arranged in the left-right direction. Taking the second buckling portion 3 as an example, as shown in fig. 2, the second buckling portion 3 includes a connecting arm 4 and a buckle 5, the connecting arm 4 may be generally C-shaped, two ends of the connecting arm 4 are respectively connected with the central portion 1, and the buckle 5 may be integrally formed on the outer side (right side) of the connecting arm 4. In use, the position of the buckle 5 in the left-right direction can be adjusted by means of the deformation of the connecting arm 4, so that the buckle 5 can be conveniently inserted into or removed from the corresponding buckling groove 63.

In some embodiments, the central portion 1 includes a pressing portion 11, a first protruding portion 12 and a second protruding portion 13, where the pressing portion 11 is used to implement pressing deformation of the central portion 1, the first protruding portion 12 and the second protruding portion 13 are connected to the pressing portion and are arranged oppositely, and the connecting arm 4 of the first buckling portion 2 and the connecting arm 4 of the second buckling portion 3 are connected between the first protruding portion 12 and the second protruding portion 13.

For example, as shown in fig. 1 and 3, the pressing portion 11 may be generally circular, the first and second protrusions 12 and 13 may be integrally formed at the lower side of the pressing portion 11, and the first and second protrusions 12 and 13 may be spaced apart and oppositely arranged in the front-rear direction.

Both ends of the first fastening part 2 may be connected to the left side of the first protrusion 12 and the left side of the second protrusion 13, respectively, and both ends of the second fastening part 3 may be connected to the right side of the second protrusion 13 and the right side of the second protrusion 13, respectively.

Therefore, the extrusion part 11 and the first buckling part 2 and the second buckling part 3 can be arranged in a staggered manner in the vertical direction, so that the fingers of a person can conveniently extend into the first cavity 21 and the second cavity 31, and in the process of realizing inward extrusion of the extrusion part 11, upward acting component force can be simultaneously applied to the extrusion part 11, and the fixing frame 100 can be further conveniently separated from the buckling groove 63.

Alternatively, the gap between the pressing portion 11 and the first buckling portion 2 in the up-down direction, and the gap between the pressing portion 11 and the second buckling portion 3 in the up-down direction may be 0 to 10mm. Specifically, as shown in fig. 3, a first gap L1 is formed between the pressing portion 11 and the first buckling portion 2, and the first gap L1 may be 2mm, 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, 9mm, 10mm. A second gap L2 is formed between the pressing portion 11 and the second buckling portion 3, and the second gap L2 may be 2mm, 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, 9mm, 10mm.

In some embodiments, the buckle 5 is provided with a first inclined surface 51, and the first inclined surface 51 is used for generating a force for pressing the connecting arm 4 inwards during the locking process of the fixing frame 100 so as to reduce the length dimension of the fixing frame 100.

Thus, in pressing down the fixing frame 100, the first inclined surface 51 may generate an inward acting component force under the action of the corresponding portion (the subsequent second inclined surface 611), thereby facilitating locking of the fixing frame 100 in place.

In some embodiments, the length dimension (the dimension in the left-right direction in fig. 1) or the width dimension (the dimension in the front-rear direction in fig. 1) of the mount 100 is 0mm to 5mm in deformation during locking and unlocking of the mount 100. For example, when the holder is locked, the length dimension of the holder 100 may be reduced, and the amount of deformation generated may be 2mm, 3mm, 4mm, 5mm, etc. The width of the holder 100 may be widened, and the amount of deformation may be 2mm, 3mm, 4mm, 5mm, etc.
