Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

Example 1:

as shown in figures 1-4, the hook component comprises a hook seat 1 and a hook buckle plate 2, and a hook 3 is fixed on the hook buckle plate 2. In the embodiment, the hook buckle plate 2 is provided with a plurality of strip-shaped bulges 2a, and the hook 3 is fixed on the strip-shaped bulges 2 a; the hook 3 is externally sleeved with a flexible sleeve 31. One side of the hook buckle plate 2 is connected with the hook seat 1 through a first connecting structure, and the other side of the hook buckle plate 2 is connected with the hook seat 1 through a second connecting structure. Couple buckle 2 detain back on couple seat 1 couple buckle 2 have the pretightning force to couple seat 1, second connection structure including locating at least one through-hole 21 on couple buckle 2, wear to be equipped with knot body 4 in each through-hole 21 respectively, knot body 4 including pressing the spacing head 41 of locating between couple buckle 2 and couple seat 1, spacing head 41 on be equipped with the portion 42 of wearing to establish of wearing to locate through-hole 21, the portion 42 of wearing to establish be equipped with slot structure 42a, slot structure 42a will wear to establish portion 42 and be two at least front ends and the foot 43 that rear end and spacing head 41 link to each other for free end, the portion 42 front end of wearing to establish still have the limit structure 44 that is located the couple buckle 2 outside, spacing head 41 and limit structure 44 between form buckle space 45, thereby spacing head 41 detain in couple buckle 2 and make the slope of foot 43 expand outward and detain in couple seat 1 in-process pressurized deformation and detain in couple seat 1 The foot 43 described above remains inclined to expand or reposition. Due to the arrangement of the slot structure 42a, the foot 43 can be caused to incline and expand outwards after the limiting head 41 is pressed and deformed, so that the penetrating part 42 is prevented from being separated. The inclined outward expansion of the foot 43 can occur during the connection and disconnection process of the buckle body 4 and/or after the connection is stable, and obviously, the disengagement of the buckle body 4 during the connection and disconnection process can be effectively avoided when the inclined outward expansion occurs during the connection and disconnection process of the buckle body 4; it is apparent that the connection stability can be further improved when it occurs after the connection of the button body 4 is stabilized. In addition, when the connection of the buckle body 4 is stable, the fastening space 45 between the position-limiting head 41 and the position-limiting structure 44 can usually satisfy the stable connection, so that the foot 43 can be in the original state at this time. The invention is very convenient to connect and disassemble, and can be conveniently realized without tools. The original state of the foot 43 means that the limiting head 41 is not deformed enough to cause the foot 43 to expand obliquely, and the foot 43 is not expanded obliquely. When the leg portions 43 are obliquely flared, the respective leg portions 43 are circumferentially spread, thereby effectively improving the positioning reliability of the penetration portion 42.

The hook seat 1 is usually horizontally and fixedly arranged, the hook buckle plate 2 is buckled on the hook seat 1, and the first connecting structure and the second connecting structure are arranged in parallel, so that the structure can conveniently adjust the transverse position of the hook buckle plate 2 on the hook seat 1.

The first connecting structure comprises an upper groove 11 and an upper hook body 22, the upper groove 11 is arranged on the upper portion of the hook seat 1 and extends transversely, the upper hook body 22 is arranged on the upper portion of the hook buckle plate 2, a notch of the upper groove 11 faces upwards, the upper hook body 22 bends downwards, and the upper hook body 22 hooks the upper groove 11. During assembly, the first connecting structures are connected first, and then the second connecting structures are connected. The lower part of the hook seat 1 is provided with a side plate 12, the lower part of the hook buckle plate 2 is provided with a lower buckle plate 23 corresponding to the side plate 12, the through hole 21 is arranged on the lower buckle plate 23, and the limiting head 41 is pressed between the side plate 12 and the lower buckle plate 23 after the hook buckle plate 2 is buckled on the hook seat 1.

An edge part 13 is formed between the side plate 12 and the front surface of the hook seat 1, the hook buckle plate 2 is buckled on the edge part 13 of the hook seat 1 when the limiting head part 41 turns over the edge part 13 in the hook seat 1 and is pressed on the side plate 12, and the foot part 43 is in an inclined outward expansion state when the limiting head part 41 turns over the edge part 13. Specifically, the side plate 12 is provided with a groove 121, the hook buckle plate 2 is buckled on the hook seat 1, in the process, the limiting head 41 turns over the ridge part 13 on the hook seat 1 to enter the groove 121, and the ridge part 13 is provided with a smooth surface. The limiting head part 41 is arched along the axial cross section of the buckle body 4; the groove 121 is arc-shaped; the surface of the limiting head 41 is closely attached to the groove 121.

The upper side and the lower side of the base of the hook seat 1 are respectively provided with an installation plate 14, the lower buckling plate 23 is connected with a supporting plate 24, and the supporting plate 24 is propped against the installation plate 14 on the lower side; the mounting plate 14 is provided with a fixed mounting hole 14 a. Due to the arrangement of the supporting plate 24 and the mounting plate 14, the strength of the hook buckle plate 2 fixed on the hook seat 1 can be effectively improved, and strong support can be formed even if the load of the hook 3 is large.

The button body 4 is of an integrated structure, and the button body 4 is made of a material which can be reset after being deformed. Specifically, the button body 4 is made of any one of plastic, rubber and silica gel; the hook seat 1 and the hook buckle plate 2 are both made of rigid materials, and the static friction coefficient between the limiting head 41 and the hook seat 1 is larger than that between the hook seat 1 and the hook buckle plate 2. Therefore, the stability of connection can be further improved after the hook seat 1 and the hook buckle plate 2 are connected with each other, and the hook buckle plate 2 is prevented from transversely sliding relative to the hook seat 1.

The slot structure 42a includes a slot 421 laterally penetrating the through-hole 42, the slot 421 divides the through-hole 42 into two foot portions 43, an opening 421a of the slot 421 is located on an outer end surface of the through-hole 42, and a bottom 421b of the slot 421 is located in a middle or root region of the through-hole 42.
