Abstract
The utility model provides a kind of quickly assembled and disassembled locking pin, solves dependence straight pin in the past and plays insurance, is difficult to repeatedly dismantle the drawback of use.This quickly assembled and disassembled locking pin, comprise pin body, if the two ends of pin body are respectively A end, B end, then B end has back-up ring, described pin body is tubular shape, on pin body tube wall, bar hole is offered near A end, have in bar hole and axially extend to A end and be formed with the tongue piece upsweeped, the position that tongue piece is bent upwards exceeds pin body, spacing to ensure that tongue piece can form block to the removable member to be installed of cross-under on pin body in its natural state, removable member to be installed can be made under pressed state smoothly to deviate from.The utility model adopts the pin body of tubular shape, and utilize the elasticity of tongue piece to carry out the installation and removal of locking pin, disassembling operations is easy, can repeatedly use, and alleviate weight.
Description
Technical field
The utility model relates to a kind of locking pin, can be applicable to the rapid-assembling/disassembling of mounting bracket.
Background technique
At present, cable wire anti-drop device all adopts straight pin to beat the form of insurance on board the aircraft.Its shortcoming is: install, dismantle inconvenience, be difficult to repeatedly use.
Model utility content
In order to overcome above-mentioned the deficiencies in the prior art, the utility model provides a kind of quickly assembled and disassembled locking pin, solves dependence straight pin in the past and plays insurance, is difficult to repeatedly dismantle the drawback of use.
Scheme of the present utility model is as follows:
A kind of quickly assembled and disassembled locking pin, comprise pin body, if the two ends of pin body are respectively A end, B end, then B end has back-up ring, described pin body is tubular shape, on pin body tube wall, bar hole is offered near A end, have in bar hole and axially extend to A end and be formed with the tongue piece upsweeped, the position that tongue piece is bent upwards exceeds pin body, spacing to ensure that tongue piece can form block to the removable member to be installed of cross-under on pin body in its natural state, removable member to be installed can be made under pressed state smoothly to deviate from.
Based on such scheme, the utility model also does following optimization and improvement further:
The extended structure initial position of bar hole internal tongue is one end away from A end of bar hole, and the initial segment of extended structure retains the part of former pin body tube wall.
The shape of the tongue piece upsweeped is circular arc; Or described in the tongue piece that upsweeps be divided into two-part, the part wherein near A end is circular arc, and the part near B end is vertical section.
This locking pin adopts sheet material to roll and forms.
Utilize locking pin to realize the structure spacing to a kind of mounting bracket, mounting bracket comprises at least two mounting plates, two mounting bracket cross-under to be installed and removed on locking pin, the outer side surface of two mounting brackets respectively by described tongue piece and back-up ring block spacing.
The beneficial effects of the utility model are:
Adopt the pin body of tubular shape, utilize the elasticity of tongue piece to carry out the installation and removal of locking pin, disassembling operations is easy, can repeatedly use, and alleviate weight.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model locking pin.
Fig. 2 is the shaft side figure of mounting structure of the present utility model.
Fig. 3 is the schematic diagram at locking pin block position.
Fig. 4 embodies the one optimization to tongue piece.
Drawing reference numeral illustrates:
1-locking pin, 11-tongue piece, 12-sells body, 2-cable wire, 3-mounting bracket, 4-pulley.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 2,3, after cable wire 2 being arranged on the bottom land of pulley 4, the cotter-pin hold of the utility model locking pin 1 alignment bracket 3 is pushed and can complete installation.During dismounting, quickly assembled and disassembled light-duty locking pin can be dismantled from support 3 by spatula 11 with hand.
Making locking pin can adopt sheet material to roll, and first can output bar hole, then roll into tubular type, be beneficial to making in flat sheet.Here tubular type for closed pipe, also can not can close and leave gap (certainly preferably making gap be positioned at the bar hole back side)
As shown in Figure 4, can do to optimize to tongue piece, tongue piece is divided into two-part, and the part wherein near A end is circular arc, and the part near B end is vertical section.Like this, rely on vertical section can block more reliably.
Claims (5)
