Utility model content

The purpose of this utility model is to solve the problems of the prior art, it is provided that a kind of anti-pinch is drawn Head.This pull head not only packaging efficiency is high, can reduce the stock caused because pull head is of a great variety, Also there is the effect preventing pull head from clamping strap.

For reaching above-mentioned purpose, this utility model adopts the following technical scheme that

A kind of anti-pinch pull head, including a pull head body；This pull head body is by the upper deck of boat and to go ashore The Split type structure of plate composition, the described upper deck of boat and the lower deck of boat are screwed together by bolt.

A kind of anti-pinch pull head as above, the described upper deck of boat includes and upper deck of boat main body one The core branch that body shapes, the screw coordinated with bolt is arranged on this core branch；Bolt passes the lower deck of boat The installation through hole being provided with is screwed onto on this core branch, with the upper and lower deck of boat of fixing connection.

Anti-pinch pull head as above a kind of, described core branch is being formed with the bottom closed of hardening of going ashore One step-like limiting section, this limiting section is embedded in the deep gouge that the lower deck of boat is provided with.

Having the beneficial effect that of technique scheme

The lower deck of boat of this utility model pull head body employing simply assembles to be fixed on by bolt goes on board Split type structure on plate.This utility model pull head body uses the split type knot that can freely change Structure, realizes changing the pattern of different brands on pull head, also not only by changing the lower deck of boat In process of production the upper deck of boat (or lower deck of boat) of stock can be produced with according to customer demand The lower deck of boat (or upper deck of boat), by the assembling that is simply spirally connected, the effect shortening the friendship phase can be played With.

The upper deck of boat of this utility model Split type structure and the lower deck of boat, also can be at pull head to clamping strap When, easily untie bolt, well solve common pull head and clamp the puzzlement of strap.

Detailed description of the invention

In order to make technical problem to be solved in the utility model, technical scheme and beneficial effect more Add clear, clear, below in conjunction with drawings and Examples, this utility model is carried out the most in detail Describe in detail bright.Should be appreciated that specific embodiment described herein only in order to explain this utility model, It is not used to limit this utility model.

A kind of as Figure 1-3 assemble pull head, the pull head body of this pull head include the deck of boat 10, The lower deck of boat 20, the core branch 30 being arranged between the deck of boat 10 and the lower deck of boat 20 is integrally formed On lower deck of boat body.

This utility model pull head body is to use the split-type structural that can freely change.As Fig. 1,2 Shown in, the split knot that this utility model pull head body is made up of the upper deck of boat 10 and the lower deck of boat 20 Structure, the described upper deck of boat 10 and the lower deck of boat 20 are screwed together by bolt 40.Produce In, the pattern of different brands can be changed by changing the lower deck of boat 20, and can be by upper and lower ship After plate 10,20 is combined according to the demand of client, by the assembling that is simply spirally connected, significantly Reduce stock.The upper deck of boat 10 of Split type structure and the lower deck of boat 20, also by untiing bolt 40, Prevent pull head from clamping strap.

The upper deck of boat 10 in the present embodiment includes the core branch integrally formed with upper deck of boat main body 30, the screw 31 coordinated with bolt 40 is arranged on this core branch 30.Bolt 40 is through going ashore The installation through hole 21 that plate 20 is provided with is screwed onto on this core branch 30, with by separate upper and lower The deck of boat 10,20 is fixedly assembled.

For promoting the packaging efficiency of this utility model pull head, under this utility model, the deck of boat 20 is provided with Deep gouge 22, core branch 30 with the bottom that the lower deck of boat 20 is combined to forming one by deep gouge 22 Scalariform limiting section 32, so that this step-like limiting section 32 is when assembling, is embedded fast and accurately Coordinate in this deep gouge 22, complete the firm combination of the upper and lower deck of boat 10,20.

Description above describe preferred embodiment of the present utility model, it is to be understood that this practicality is new Type is not limited to above-described embodiment, and should not regard the eliminating to other embodiments as.By this The enlightenment of utility model, those skilled in the art combine known or prior art, knowledge is carried out Change also should be regarded as in protection domain of the present utility model.
