Abstract
The utility model discloses a central electrical appliance box bolt locking structure for an automobile. The bolt locking structure is connected with a shell of a central electrical appliance box and is formed by injection molding of engineering plastics. The bolt locking structure comprises a cavity used for arrangement of the bolt square head portion, and the bottom of the cavity is square, the top of the cavity is an opening, one side portion of the cavity is an opening, and the other three side portions of the cavity are respectively provided with an inward protruded block on the top. The protruded blocks are used for abutting against the bolt head portion after the bolt head portion enters the cavity, and therefore the bolt head portion can not slip off from the cavity. The bolt locking structure further comprises an elastic buckle which is formed by injection molding of the engineering plastics, the elastic buckle is placed on the side portion of the opening of the cavity, in the process of installation of a bolt, the bolt head portion presses the elastic buckle, and therefore the elastic buckle recovers an original state so that the protruded portion of the elastic buckle rightly and tightly abuts against the bolt head portion after the bolt head portion is pushed into the cavity from the opening side portion in a sliding mode. Thus, the bolt can be prevented from slipping off from the cavity.
Description
Technical field
The utility model belongs to automobile electrical appliances component technical field, particularly a kind of automobile central electrical appliance kit bolt-locking structure.
Background technique
In the prior art, relating in the automobile electrical appliances component needs fixing occasion, adopt bolt and nut to fix with the support fastener more and fix, and the fondational structure of automobile electrical appliances component often adopts the engineering plastics injection moulding to form.In this kind structure, bolt adopts welding procedure to fix bolt at sheet metal part, and bolt adopts the mold insert Shooting Technique to fix bolt at engineering plastics.Although the needs that the means of fixation of this bolt can proof strength, when the needs repair and replacement, the cost of replacing is very high, even can't change at all.
The model utility content
The purpose of this utility model provides the structure of fixing bolt in a kind of automobile central electrical appliance kit bolt-locking structure this patent, to solve in the automobile electrical appliances component replacing problem based on fixing bolt in the engineering plastic structure.
The technical solution of the utility model is, a kind of automobile central electrical appliance kit bolt-locking structure, described bolt-locking structure links to each other with the housing of central electrical part holder, and adopt the engineering plastics injection molded, described bolt-locking structure comprises that a bottom for the bolt square head portion of packing into is foursquare cavity, the top of this cavity is uncovered, and a sidepiece of cavity is uncovered, in addition three sidepieces of cavity all have an inside projection at the top, this projection can not deviate from it for the head that compresses bolt after the head of bolt enters described cavity in this cavity
Described bolt-locking structure also comprises one by the Elastic buckle of described engineering plastics injection molded, this Elastic buckle is positioned at the uncovered sidepiece of described cavity, when construction bolt, the head of bolt is pressed described Elastic buckle, so that after the head of bolt is pushed into described cavity from uncovered sidepiece cunning, described Elastic buckle restPoses, so that the protuberance of Elastic buckle just in time tightly compresses the head of bolt, prevents that bolt from deviating from described cavity.
The locking mechanism of described bolt can adapt to the bolt of M5～M8, and the intensity of described bolt-locking structure can reach 5Nm～10Nm.
Bolt-locking structure of the present utility model, comprise the constraint of bolt six-freedom degree and the releasing of one degree of freedom constraint, bolt can be fixed after direction that can constraint relief is packed into this structure reliably, can effectively compensate simultaneously the alignment error of screw bolt and nut, bolt also can be removed on the direction of constraint relief very easily.So fixing reliable in the use, simultaneously dismounting and replacing are convenient, and shaping die is simple in processing, and moulding process is reliable simultaneously, and this structure is worthy of popularization in central electric terminal box vehicle use neutralizes other electronic apparatus series products.

Embodiment
Fig. 1 is an embodiment of the present utility model, 2 situations that the bolt-locking structure connects side by side in the automobile central electrical appliance kit, 1---the locking mechanism of the bolt of not packing into, 2---the locking mechanism of the bolt of packing into, wherein, 101---Elastic buckle, 102---cavity, 1021,1022 and 1023---projection, 103---bolt.
Fig. 2 is the sectional view of Fig. 1, wherein, 104---nut, 105---electronic device.
Bolt-locking structure of the present utility model is connected with the housing of central electrical part holder, and adopt the engineering plastics injection molded, bolt-locking structure 1 or 2 comprises that a bottom be used to bolt 103 square head portion of packing into is foursquare cavity 102, the top of this cavity 102 is uncovered, and a sidepiece of cavity 102 is uncovered, another three sidepieces of cavity 102 all have an inside projection 1021/1022/1023 at top, this projection can not deviate from it for the head that compresses bolt after the head of bolt 103 enters described cavity 102 in this cavity 102
The bolt-locking structure also comprises one by the Elastic buckle 101 of described engineering plastics injection molded, this Elastic buckle 101 is positioned at the uncovered sidepiece of described cavity 102, when construction bolt 103, the head of bolt is pressed described Elastic buckle 101, so that after the head of bolt is pushed into described cavity 102 from uncovered sidepiece cunning, described Elastic buckle 101 restPoses so that the protuberance of Elastic buckle just in time tightly compresses the head of bolt, prevents that bolt 103 from deviating from described cavity.
After loading onto electronic device 105, screw in again nut 104, the lighting outlet of electronic device 105 is just by bolt 103 and nut 104 lockings like this.
The locking mechanism of bolt of the present utility model can adapt to the bolt of M5～M8, and the intensity of bolt-locking structure can reach 5Nm～10Nm.
