Description

The drawer of wheel bolt cap

Technical field

The utility model relates to a kind of drawer of wheel bolt cap, comprises two spring-latchs of establishing toward each other, and described a plurality of spring-latchs are respectively equipped with on its free end towards pulling out each other and collude.

Background technology

General wheel bolt is positioned at exterior bolt cap, is covered by the plastic cap that puts, before change of wheels need be outwarded winding wheel bolt, must earlier described plastic cap be pulled out from bolt cap, especially when bolt cap is arranged with in the car rim, more need a kind of special instrument, for example nipper.

Be useful at present the stirrup shape drawer of the cap of the wheel bolt head of choosing, described drawer is stirrup shape and has elastomeric slightly arm (DE 7627124 U), described arm bends inwards and colludes to make to pull out, and utilizes described arm user can stretch between car rim and the cap.In DE 9015848 U1 a cases, pull out to collude and make resilient tongue, its free end from stirrup shape arm and stirrup shape arm keeps certain distance, inwardly bending.Can form the connection protuberance between described a plurality of tongues, described connection protuberance section becomes bending-like, makes can form one between protuberance and the tongue and along the circumferential direction be osed top hexagonal cross-section pipeline section.

The utility model content

The purpose of this utility model provides a kind of drawer of wheel bolt cap, the cap of can effectively choosing.

In order to reach above-mentioned purpose, the utility model provides a kind of drawer of wheel bolt cap, the wherein said free end direction convergent that faces spring-latch that colludes toward each other that pulls out, to become a taper, the arm that the spring-latch free end be can be slick and sly shape forms.Described a plurality of spring-latch axially extends from a body, and between spring-latch, be provided with an axial guiding protuberance along body periphery direction, described guiding protuberance is with a fluting and described spring-latch interval, described a plurality of pulling out colluded the outstanding described guiding protuberance of axially extension, and its outstanding length is roughly itself length.

According to the utility model, it pulls out the inclined-plane that colludes can to utilize drawer, drawer is shifted onto on the described hexagon cap, and described a plurality of spring-latch elasticity are strutted, and the inclined-plane cooperates cap hexagon each limit respect to one another, make each limit of spring-latch rotary alignment of drawer, form tangent up to them and these limits.Thus, described instrument can axially align described cap simultaneously.Above-mentioned alignment actions can not be subjected to the guiding protuberance established along the periphery direction between spring-latch and hinder because described a plurality of pull out to collude axially protrude in outside the guiding protuberance.Because described a plurality of spring-latchs are with fluting and guide protuberance at interval, and can freely strut.When continuing to shift onto instrument on the cap, cap can axially align and enter between described a plurality of guiding protuberance.The outside of guiding protuberance is positioned on the perisporium of car rim recess, and the bolt headband of wheel bolt the cap that puts, and indent is located in the car rim recess.Slide even have slot, the outside of guiding protuberance still guides on perisporium, buckle into the shoulder on the cap up to the hook part, and cap can be by tool spindle when pulling up.

Preferably, describedly a plurality ofly pull out that to collude vertical section tapered, and axial length is greater than maximum radial thickness, the truncation width is greater than axial length, described a plurality of pull out to collude axially protrude out for outside the guiding protuberance, its outstanding length surpasses the line shaft of himself to length.This one pulls out hooking structure design, can greatly simplify aforementioned aligning operation.

The guiding protuberance launches at section, and the common hexagonal cross section pipeline section that forms in the cross section of guiding protuberance and spring-latch, described hexagonal cross-section pipeline section vertically cuts along guiding protuberance and spring-latch.Therefore, turning tool back and forth unclamps and by the guiding protuberance securing cap is changeed.

Described body can be designed to tube seat, its comprise one can ccontaining a plurality of caps axial length, and have an embolism, in order to clog the end of body with respect to spring-latch.Preferably, described tube seat has a length, and the cap of all four wheels all can be placed in the described tube seat.The general length of cap is between 18 to 22mm, so the pipe range of ccontaining 20 caps is approximately 380 to 450mm.By this structure that is designed to tube seat, when changing wheel, after the cap of all four wheels is installed new wheel, all can stay in the instrument, so can not lose.

Further preferably, spring-latch is located on the pipeline section with the guiding protuberance, and described pipeline section was fixed on the body afterwards.This pipeline section for example can be spring steel or senior plastics are made, and relatively described body itself then can be made by iron or plastics.In addition, also instrument can be designed to two-piece type, give then mutually by fixing, wherein said two parts sections can be selected different shapes, for example aforementioned, the pipeline section that will have spring-latch and guiding protuberance is designed to hexagon, and body remainder section is then rounded.

In addition, by this two-piece design, described pipeline section can be connected with body, wherein said pipeline section and body are separable, and the described thus pipeline section with spring-latch and guiding protuberance selectively is coupled in the body with a plurality of tube seats.

Above-mentioned by two parts mutually and the embodiment that is fixed together, its special advantage is that the internal diameter clear span of body designs greatlyyer than the internal diameter clear span of pipeline section.Such project organization even cap tilts, also can push body with cap easily, can not be stuck in the tube seat.

When the pipeline section with spring-latch and guiding protuberance when being fixed on the body separably, each pipeline section selectively couples with body in then a plurality of pipeline sections with different size, makes described pipeline section to cooperate hexagonal various criterion size nut.Set of tools of the present utility model is made up of the wide pipeline section in a body and a plurality of various criterion footpath, and described pipeline section has two and comprises and pull out the spring-latch that colludes and two and be located at and guide protuberance between the spring-latch, and described pipeline section selectively couples separably with described body; Preferably, described internal diameter of tube body clear span is greater than described internal diameter clear span with the wide pipeline section in maximum standard footpath.

Wherein, can design each pipeline section and all can select to be spirally connected with described body, the screw thread of all pipeline sections is all identical, and corresponding with the phase double thread of body.Perhaps can in set of tools, be provided with one or more tube reducing screw adapters (reduction screw adaptor), described tube reducing screw adapter is spirally connected by itself screw thread and described body, and screw thread less on its another screw thread and described one of them pipeline section of a plurality of pipeline section screws togather.

In order further to understand the utility model is to reach technology, means and the effect that predetermined purpose is taked, see also following about detailed description of the present utility model and accompanying drawing, believe the purpose of this utility model, feature and characteristics, can get one thus gos deep into and concrete understanding, yet appended graphic only provide reference and explanation are not to be used for the utility model is limited.
