Abstract

An air filter box for a vehicle comprises an upper casing, a lower casing, a screw and a filter core. A through hole is formed in the periphery of the upper casing, a round hole matched with the through hole is formed in the periphery of the lower casing, the upper casing is vertically connected with the lower casing through the screw in a splicing mode, the filter core is arranged in an inner cavity formed by splicing the upper casing and the lower casing, the through hole is in the shape of a Chinese character 'ao', the through hole comprises a narrow section and a wide section, the hole diameter of the narrow section is smaller than the diameter of the thread head of the screw, and the hole diameter of the wide section is smaller than the diameter of the thread head of the screw. The air filter box for the vehicle is simple in structure and convenient to use, and the through hole in the periphery of the upper casing is specially designed. When the upper casing is disassembled, the screw is limited in the through hole, the problem of loss caused by reversely sliding out cannot occur, one side of the upper casing and one side of the lower casing are designed to be in hinge connection, two screws are reduced, and therefore cost is reduced.

Description

Vehicle air filter box

Technical field

The utility model relates to vehicle component, relates in particular to a kind of vehicle air filter box.

Background technique

Vehicle air filter box is the vitals of air inlet system for vehicle, is the device that air is purified, and it can will enter the air-filtering of motor, and foreign material, dirt are filtered in the filter core front, and the air that assurance enters engine cavity is clean.

Traditional vehicle air filter box consists of upper shell, lower shell body, and upper shell, lower shell body are connected by screw into an integral body, in the inner chamber that both form, filter core is set, filter core is separated into two cavitys by inner chamber, wherein, be provided with suction port on lower shell body, be provided with air outlet on upper shell.

, upper shell need to be unloaded from lower shell body more during renew cartridge when needs, after unloading, be easy to lose for the screw that connects upper shell and lower shell body, increase cost.

The model utility content

Based on this, for above-mentioned technical problem, provide a kind of vehicle air filter box.

For solving the problems of the technologies described above, the utility model adopts following technological scheme:

A kind of vehicle air filter box, comprise upper shell, lower shell body, screw and filter core, the periphery of described upper shell is provided with through hole, the periphery of described lower shell body is provided with the circular hole with described through hole adaptation, described upper shell and lower shell body connect by the upper and lower amalgamation of described screw, described filter core is located in the inner chamber of described upper shell and lower shell body amalgamation formation, described through hole is convex shape, it comprises narrow section and wide section, the aperture of described narrow section is less than the diameter of the screw head of described screw, and the aperture of described wide section is greater than the diameter of the screw head of described screw.

The axial inwall of wide section of described through hole is provided with the internal thread with the outside thread adaptation of described screw head.

Described upper shell and lower shell body are hinged by hinge in a side.

The utility model is simple in structure, easy to use, through hole to the upper shell periphery has carried out particular design, when the dismounting upper shell, screw can be limited in through hole, can not occur oppositely to skid off and the problem lost, and a side of upper shell and lower shell body is designed to chain connection, reduced by two screws, reduced cost.

The accompanying drawing explanation

Below in conjunction with the drawings and specific embodiments, the utility model is elaborated:

Fig. 1 is decomposition texture schematic diagram of the present utility model;

The structural representation that Fig. 2 is through hole of the present utility model;

Fig. 3 is structural representation of the present utility model.

Embodiment

As Figure 1-3, a kind of vehicle air filter box, comprise upper shell 1100, lower shell body 1200, screw 1300 and filter core 1400.

The periphery of upper shell 1100 is provided with through hole 1110.

The periphery of lower shell body 1200 is provided with the circular hole 1210 with through hole 1110 adaptations.

Upper shell 1100 and lower shell body 1200 are generally working of plastics, and its intensity is much smaller than the intensity of screw 1300, therefore, screw 1300 in rundown process, can nature generate screw thread in circular hole 1210.

Certainly, circular hole 1210 also can be processed into tapped hole in advance.

Upper shell 1100 and lower shell body 1200 are by screw amalgamation connection Shang Xia 1300.

Particularly, as shown in Figure 2, through hole 1110 is convex shape, it comprises narrow section 1111 and wide section 1112, the aperture of narrow section 1111 is less than the diameter of the screw head 1310 of screw 1300, the aperture of wide section 1112 is greater than the diameter of the screw head 1310 of screw 1300, like this, in dismounting upper shell 1100 processes, after the screw head 1310 of screw 1300 unclamps with the circular hole 1210 on upper shell 1100, the screw head 1310 of screw 1300 can be stopped by the shouldered wall of through hole 1110 the axial inwall 1113 of wide section 1112 (be through hole 1110), avoided screw 1300 oppositely to skid off and the problem lost from through hole 1110.

When the screw head 1310 of screw 1300 is stopped by the shouldered wall of through hole 1110, can continue to turn screw 1300, the intensity of the upper shell 1100 of making due to working of plastics is much smaller than the intensity of screw 1300, turn the formation on the axial inwall 1113 of wide section 1112 of through hole 1110 of meeting nature in process and the internal thread of the outside thread adaptation of screw head 1310, screw head 1310 is connected with this internal thread, and the situation of having avoided screw 1300 to damage miscellaneous part in the interior slip of through hole 1110 occurs.

Be understandable that, also can process in advance the internal thread with the outside thread adaptation of screw head 1310 on the axial inwall 1113 of wide section 1112 of through hole 1110.

As shown in Figure 3, can be hinged by hinge 1500 at upper shell 1100 and lower shell body 1,200 one sides, hinge 1500 plays location and replaces the function of screw 1300, can reduce by two screws 1300, has reduced cost.

Filter core 1400 is located in the inner chamber of upper shell and lower shell body amalgamation formation, and this inner chamber is separated into to two cavitys.

But, those of ordinary skill in the art will be appreciated that, above embodiment is only for the utility model is described, and not be used as restriction of the present utility model, as long as in connotation scope of the present utility model, to the above embodiment's variation, modification, all will drop in claims scope of the present utility model.
