Abstract

The utility model relates to a connection component for plastic inner decoration elements and vehicle body sheet metal holes, comprising a male pin and a pin hole. The pin hole comprises an end cap and four supporting rods with elasticity which are arranged under the central hole of the end cap and are arranged into a round, and the lower end of each supporting rod is provided with a block hook. The plug post of the male pin comprises three parts, and the lower part, the middle part and the upper part are longitudinally divided into four equant structure sections by prisms. The structure in each section being same, the lower part is a conical initial segment, the middle part is an annular fixed segment with a groove, and the upper part is also a drawing segment whose lower end is in a conical sandglass type. When inserted in the pin hole, the four longitudinal section segments of the male pin form a passage where the four supporting rods of the pin hole slide up and down. Compared with the prior art, the utility model has the advantages of simple structure, easy use, high efficiency, time saving and labor saving.

Description

A kind of plastics combination pin

Technical field

The utility model is a kind of coupling member that is used for plastics inside gadget and car body stamping holes, and it relates to the raising on structural improvement of existing product and the performance.

Background technique

When plastics inside gadget and car body panel beating connected, usual way was with self threading pin the plastics inside gadget to be fixed, and is that the self threading pin head exposes with the self threading pin method directly, though that installation firmly influences very much is attractive in appearance.Because of the self threading pin head is exposed to the outside, whole inharmonious with inside gadget, time-consuming, the effort of these traditional methods exists distortion of materials and damage simultaneously.Be not suitable for the connection of plastics inside gadget and plastics inside gadget.

Summary of the invention

The purpose of this utility model designs at the deficiency that exists on the above-mentioned prior art just a kind of plastics of new structure combination pin is provided, and uses this kind plastics combination pin to make installation become very convenient, and is time saving and energy saving, and the efficient height.

The purpose of this utility model realizes by following measure:

This kind plastics combination pin, it is made up of pin and pin-and-hole, its structural design features is, pin-and-hole by end cap and be arranged on surround below the end cap center hole circular, rubber-like pintongs pole constitutes, in the lower end of each lobe pole a trip is arranged all, the inserting column of pin is formed by three part-structures, the bottom, the middle part and top all by prism between the structural area that vertically is separated into four five equilibriums, structure in each is interval is identical, the bottom is the The initial segment of taper, the middle part is the holding part of endless belt groove, top also is the section of liter of pulling out of the tapered hourglass shape in lower end, and four vertical segments of pin form the pin-and-hole passage to lower slider of pintongs pole on every side when it inserts pin-and-hole.

Description of drawings

The drawing of accompanying drawing is described as follows:

Fig. 1 be the utility model product structural representation

Fig. 2 is mounting point of the present utility model and structural representation

Fig. 3 pulls out assembling and the structural representation of raise-position when putting for the utility model product is in

Embodiment

Below with reference to drawings and Examples the utility model is further described:

Shown in accompanying drawing 1-3, this kind plastics combination pin, it is made up of pin 2 and pin-and-hole, its structural design features is, pin-and-hole by end cap 1 and be arranged on surround below end cap 1 center hole circular, rubber-like pintongs pole 3 constitutes, in the lower end of each lobe pole 3 trip 4 is arranged all, the inserting column of pin 2 is formed by three part-structures, the bottom, middle part and top all by prismatic 9 between the structural area that vertically is separated into four five equilibriums, structure in each is interval is identical, the bottom is the The initial segment 5 of taper, the middle part is the holding part 6 of endless belt groove, top also for the tapered hourglass shape in lower end pull out the section of liter 8, four vertical segments of pin 2 form the passage to lower slider of the pintongs pole 3 around the pin-and-hole when it inserts pin-and-hole.

During use, earlier pin-and-hole is inserted in the positioning hole of the two packaged plaques that need connection, again pin 2 is inserted in the pin-and-hole, surrounding on the pin-and-hole is circular, rubber-like pintongs pole is dropped on along in the formed passage between the structural area of vertical four five equilibriums on the pin 2 for 3 this moments, and along with pin 2 advances downwards and moves upward along above-mentioned passage, at first the The initial segment 5 along the taper of bottom moves upward, its folder colludes 4 and will be installed in the annular recess of middle part holding part 6, effect by pintongs pole 3 outside expandings links together two packaged plaques securely, finishes assembly process.When maintenance, when pulling out, needs rise whole plastics combination pin, push pin 2 downwards, pintongs pole 3 on the pin-and-hole will break away from the annular recess of holding part 6 and enter into the tapered hourglass shape in pin 2 tops pull out the section of liter 8, at this moment, the folder of pole 3 colludes 4 can be engaged on the concave point place of pulling out the section of liter 8 tapered hourglass shapes, at this moment just can successfully whole plastics combination pin be extracted.

The utility model compare with present technology have simple in structure, easy to use, the high advantage of time saving and energy saving and efficient.
