Description

Fastener structure is improved

Technical field

The utility model is related to a kind of Fastener structure to improve, espespecially one above can be quick for the use of work high above the ground fastening safety belt Eye-splice and pressing are separated and the safe Fastener structure for reaching anti-dropout.

Background technology

Be typically for giving in work high above the ground engineering using setting fastening in as protect with belt buckle (10, such as the 1st figure institute Show), it is mainly made up of a pin thread 11 with a box 12, and the male and female button 11,12 can be by metal stamping, forging, casting, pressure Casting mode is combined or is integrally formed, and a plate 111 is set for being interlocked with box 12 in the side of pin thread 11, and plate 111 is in end Both sides are relative set one in ＜ shapes draw-in groove side 112 and prolong its bottom and form a projection blocking part 113, box 12 in pin thread 11 it The corresponding port of plate 111 sets a pivot catching groove 121, the both sides of pivot catching groove 121 are symmetrical be pivoted one in/shape has oblique inner retaining side 123 Catch 122 receive the butted positioning of an outside elastic propping piece 124 respectively, the shape at the lower section of bottom correspondence pivot catching groove 121 of two catch 122 The button room 125 of positioning is buckled into for convex blocking part 113 into one, and is respectively equipped with male and female button 11,12 sides and is worn for safety belt Set connection ushers to seat 114,126, when using (as shown in Figure 2), with the plate 111 of pin thread 11 toward box 12 pivot catching groove 121 It is pressed downward buckling into, the bottom of the plate 111 section blocking part 113 of pin thread 11 is buckled into the button room 125 of box 12, by pivot catching groove 121 liang of side-lens 122 can respectively by outside elastic propping piece 124 inside opposite bullet support under, make two outer side bayonet slot sides 112 of plate 111 Just can in opposite directions be clamped by the oblique inner retaining side 123 of catch 122 respectively and abutted, the fastening for reaching male and female button 11,12 links to provide peace The full purpose with being able to reach the safeguard protection in construction with setting fastening staff.

The box 12 of above-mentioned belt buckle 10 is only through two catch 122 of pivot catching groove 121 with the opposite bullet of elastic propping piece 124 The plate 111 of bulging tug pin thread 11, makes the blocking part 113 of plate 111 be unlikely to depart from button room 125, but box 12 is fastening public affairs Only it is to stick to the ＜ shape draw-in grooves in plate 111 with 123 jiaos of ora terminalis of oblique inner retaining side by two catch 122 in the fastening structure intensity of button 11 2 points when making on 112 with side support positioning, the external force shadow for easily making two catch 122 of box 12 be applied by non-user Ring, it is impossible to be brought into close contact and have space 127, cause fastening dynamics, the tight ness rating of support positioning plate 111 all more weak, Once two catch 122 are pressed inward against by external force accidentally, certainly will easily produce pin thread 11 to depart from box 12 and cause what safety belt was released Danger, i.e., be more that a side is influenceed by external force, still there is the doubt for causing dangerous and safe operation.

Utility model content

Main purpose of the present utility model is to provide a kind of Fastener structure improvement.

To reach above-mentioned purpose, the utility model uses following technical scheme：

A kind of Fastener structure improvement, comprising：One pin thread, a box, a plate is set for being interlocked with box in the side of pin thread Close, box sets a pivot catching groove in port corresponding with plate, the both sides of pivot catching groove are symmetrical be pivoted one in/shape has oblique inner retaining side Catch, respectively by the one first butted positioning of elastic propping piece, a button room is formed in the bottom correspondence pivot catching groove lower section place of two catch.

Plate sets a button hook groove along end both sides are relative, prolongs its bottom and sets the blocking part that a tool supports tug hole, two gears of box In a snap fit groove is set respectively with button hook groove relative position, it is the second elastic propping piece of torque spring that button interior sets one to piece；Make plate It is pressed downward buckling into toward pivot catching groove, wears plate and be buckled in pivot catching groove, and the blocking part of plate is buckled into button room, makes pivot catching groove Two catch it is relative by the first elastic propping piece opposite bullet support clamping plate inside, be in negative and positive symmetry angle using button hook groove and snap fit groove Hook is engaged, and makes plate to combine closely and first support positioning is formed between two catch, and blocking part buckles into interior, makes card The bottom in tug portion supports tug hole and supports the second elastic propping piece of tug relatively, under the reaction force by the second elastic propping piece, makes blocking part tight Indoor formation second support positioning is buckled in reference to pivot, it is in two by the first elastic propping piece to make plate relative by two catch that it detains room The reaction force of the point strong point and the elastic propping piece of bottom second reaches the fastening that triangulation point supports positioning in the 3rd strong point.

The pin thread that it sets a tool plate is interlocked with the box of a tool button room, and it is butted with one first that box sets one in button interior Part is engaged the catch of butted positioning, and button of the angle less than 90 degree is respectively equipped with using plate two sides corresponding with two catch Hook groove and snap fit groove, make pin thread wear buckle into the button interior of box can be by the button hook groove of plate and two catch snap fit grooves in negative and positive pair Angle is claimed to combine closely to form first support positioning, and the bottom of plate is provided with a blocking part and relative can be butted on button interior and set Have on one second elastic propping piece, indoor formation second branch is buckled in by the pivot that can be combined closely under the reaction force of the second elastic propping piece Support positioning, thereby, makes the plate of pin thread be incorporated into button interior and makees the fastening that triangulation point supports positioning, no matter reaches belt buckle Insertion is fastened or pressing is absolved and can promote safety in utilization and buckle fastness.
