CN201531490U - Clamp hook structure - Google Patents

Abstract

The utility model discloses a clamp hook structure, which is fixed on a plastic piece. The clamp hook structure comprises a clamp hook cantilever, one end of the clamp hook cantilever is fixed onto the plastic piece while the other end is provided with a barb, and an included angle between the clamp hook cantilever and a combining surface on the barb is an acute angle. The barb in the clamp hook structure can be combined with another barb to form reverse fastening, and when stressed, the clamp hook can be fastened tightly without being easy to be separated. Besides, the clamp hook structure is adaptable to assembly occasions needing the clamp hook to fasten forever.

Description

Hook structure

[technical field]

The utility model relates to a kind of hook structure, and particularly a kind of grab junction plane back-off is not allowed caducous hook structure.

[background technique]

Injecting products is widely used in industries such as electronics, electromechanics now, the grab design is a product link Fixed Design mode the most frequently used in the injecting products, common grab is with taper pin moulding grab junction plane, because the angle between grab junction plane and the grab cantilever meets at right angles or the obtuse angle, so grab is easy to throw off when stressed.Existing hook structure is concrete with reference to as follows:

Fig. 1 illustrates two schematic representation that grab cooperatively interacts in the existing hook structure.

Fig. 2 illustrates the schematic representation of grab and taper pin bonding state in the existing hook structure.

With reference to Fig. 1, shown in Figure 2, existing hook structure, it is fixed on the plastic parts 300 ', this hook structure comprises:

Grab cantilever 1 ', the one end be fixed in above-mentioned plastic parts 300 ' on, the other end be provided with a barb 11 ', and this grab cantilever 1 ' and above-mentioned barb 11 ' on junction plane 111 ' between angle meet at right angles or the obtuse angle.

In present embodiment, angle between the junction plane on grab cantilever and the barb meets at right angles or the obtuse angle, so when two grabs engage mutually, after being subjected to the external force effect, the junction plane of these two grabs can produce a mutually exclusive power respectively, makes two grabs be easy under the effect of this external force separately like this, is not suitable for being applied to needing the disposable stuck assembly yard of grab to close, when this hook structure moves back film, with taper pin 2 ' can move back film along Fig. 2 arrow direction.

In view of this, in fact be necessary to propose a kind of hook structure, in this hook structure barb with can form back-off after barb combine, when grab is stressed, can engage very tightly, be not easy to separate, this hook structure is fit to be applied to need the disposable stuck assembling occasion of grab.

[summary of the invention]

Therefore, the utility model provides a kind of hook structure, to realize utilizing this hook structure can realize the disposable stuck purpose of grab.

For achieving the above object, the utility model provides a kind of hook structure, and it is fixed on the plastic parts, and this hook structure comprises:

Grab cantilever, one end are fixed on the above-mentioned plastic parts, and the other end is provided with a barb, and the angle between the junction plane on this grab cantilever and the above-mentioned barb acutangulates.

Especially, also be provided with opening on the above-mentioned grab cantilever.

Compared to prior art, in the hook structure of the present utility model, when two grabs in conjunction with after form the state of two barb back-offs, make grab and grab be not easy to separate like this, be fit to be applied to the disposable stuck assembling occasion of need grab.

For the purpose of this utility model, structure characteristics and function thereof are had further understanding, conjunction with figs. is described in detail as follows now:

Fig. 1 illustrates two schematic representation that grab cooperatively interacts in the existing hook structure.

Fig. 2 illustrates the schematic representation of grab and taper pin bonding state in the existing hook structure.

Fig. 3 illustrates the structural representation of the utility model hook structure.

Fig. 4 illustrates two schematic representation that grab cooperatively interacts in the utility model hook structure.

Fig. 5 illustrates the schematic representation of grab and taper pin bonding state in the utility model hook structure.

Fig. 6 illustrates the schematic representation of grab and taper pin separated state in the utility model hook structure.

[embodiment]

With reference to Fig. 3-shown in Figure 6, hook structure of the present utility model, it is fixed on the plastic parts 300, and this hook structure comprises:

Grab cantilever 1, the one end is fixed on the above-mentioned plastic parts 300, the other end is provided with a barb 11, and the angle between the junction plane 111 on this grab cantilever 1 and the above-mentioned barb 11 acutangulates, because of above-mentioned angle is an acute angle, so two grabs are in conjunction with forming a back-off state between the junction plane 111 of latter two barb 11, when grab is stressed, can tightly block, be not easy to break away from, wherein, 1 also is provided with opening 12 on this grab cantilever, and this opening 12 matches with taper pin 2, and making only needs along arrow direction among Fig. 6 grab and taper pin 2 are separated taper pin 2 when grab moves back film.

Claims (2)

1. hook structure, it is fixed on the plastic parts, it is characterized in that, and this hook structure comprises:

Grab cantilever, one end are fixed on the above-mentioned plastic parts, and the other end is provided with a barb, and the angle between the junction plane on this grab cantilever and the above-mentioned barb acutangulates.

2. hook structure as claimed in claim 1 is characterized in that, also is provided with opening on the above-mentioned grab cantilever.
