Description

Safety belt lock catch

Technical field

The utility model relates to a kind of safety belt lock catch.

Background technology

Safety strap is automotive safety protection vitals, the connection of safety strap is to realize by snap close, safety belt lock catch mainly comprises pin thread and box, pin thread is connected on safety strap, box is fixed on a side at seat, by pin thread and box, be connected to realize the fixing of safety strap, current safety belt lock is buckled in belt tensioning power when larger, safety strap is to pull pin thread to outside more energetically, can cause the impact that the latching device of box is subject to pin thread to pull power cannot easily use dropout, need the trip push button that uses larger strength just can press on box to realize dropout, children like this, old man and women etc. can cannot thread off smoothly due to hand force quantity not sufficient, there is larger potential safety hazard.

Utility model content

The purpose of this utility model is to provide a kind of safety belt lock catch, and box has adopted brand-new latching device, and latching device is opened the impact that dropout is not subject to pin thread application force, has feature rational in infrastructure, esy to use, safe and reliable.

For achieving the above object by the following technical solutions:

A kind of safety belt lock catch, comprise box and pin thread, described box comprises housing, in housing, be provided with flute profile seat, it is characterized in that: have the rear portion of a camber member to be fixed on flute profile seat, the front portion of camber member is provided with latch hook, camber member top is provided with lock pin, the front portion of flute profile seat coordinates formation pin thread socket with trip push button, the position of the corresponding lock pin in trip push button both sides is provided with dropout groove, the two ends of lock pin are passed the L shaped locking slot of flute profile seat both sides and are placed in dropout groove, the bottom of pin thread socket is provided with slide block, slide block both sides are provided with orienting lug, orienting lug is contained in the guide groove of flute profile seat, there is the bottom-hinged of an expelling means on slide block, between expelling means middle part and camber member, be provided with spring, the top of expelling means arranges curve, curve is enclosed on lock pin.

Described flute profile seat both sides are provided with button guide groove, and trip push button is provided with the guide block coordinating with button guide groove.

When the utility model is threaded off, only need press trip push button, after pressing trip push button band pendulum lock pin, move, and expelling means is rotated backward, expelling means rotates the power making the compressing of camber member backward to be cancelled, and the latch hook of camber member front portion upwarps the lockhole that departs from pin thread, and expelling means rotates backward and makes the application force of spring be applied to expelling means bottom in addition, thereby spring promotes slide block, reach ejects pin thread, completes dropout; When the utility model is threaded off, the rotation of expelling means and the movement of lock pin are not affected by the application force of pin thread, the front portion of camber member is provided with latch hook and is automatically replied by self elastic deformation, during dropout, be applied to the impact that application force on trip push button is not subject to pin thread pulling force, promote safety belt lock catch reliability and safety.

The specific embodiment

As Figure 1-4, a kind of safety belt lock catch, comprise box and pin thread, described box comprises housing 1, in housing 1, be provided with flute profile seat 2, there is the rear portion of a camber member 3 to be fixed on flute profile seat 2, the front portion of camber member 3 is provided with latch hook 31, camber member 3 tops are provided with lock pin 4, the front portion of flute profile seat 2 and trip push button are joined 5 and are closed formation pin thread socket, the position of the corresponding lock pin 4 in trip push button 5 both sides is provided with dropout groove 51, described flute profile seat 2 both sides are provided with button guide groove 23, trip push button 5 is provided with the guide block 52 coordinating with button guide groove 23, the two ends of lock pin 4 are passed the L shaped locking slot 21 of flute profile seat 2 both sides and are placed in dropout groove 51, the bottom of pin thread socket is provided with slide block 6, slide block 6 both sides are provided with orienting lug 61, orienting lug 61 is contained in the guide groove 22 of flute profile seat 2, there is the bottom-hinged of an expelling means 7 on slide block 6, between expelling means 6 middle parts and the fixed part 32 of camber member 3, be provided with spring, the top of expelling means 7 arranges curve 71, curve 71 is enclosed on lock pin 4.

When the utility model pin thread and box are pegged graft, pin thread withstands slide block and moves backward, after slide block, moving expelling means rotates forward, expelling means rotates compressing lock pin under the effect of spring, lock pin is moved down along L shaped locking slot, lock pin and then compressing camber member are anterior, the latch hook of camber member front portion is snapped fit onto in the lockhole of pin thread, remove the pressure that pin thread pushes through, expelling means promotes slide block and lock pin reach under the effect of spring, lock the front end of locating L shaped locking slot in the pendulum lock pin two ends that slightly move forward and can not thread off easily, thus locking pin thread and female mouth; And while threading off, only need press trip push button, after pressing trip push button band pendulum lock pin, move, and expelling means is rotated backward, expelling means rotates the power making the compressing of camber member backward to be cancelled, and the latch hook of camber member front portion upwarps the lockhole that departs from pin thread, and expelling means rotates backward and makes the application force of spring be applied to expelling means bottom in addition, thereby spring promotes slide block, reach ejects pin thread, completes dropout; When the utility model is threaded off, the rotation of expelling means and the movement of lock pin are not affected by the application force of pin thread, the front portion of camber member is provided with latch hook and is automatically replied by self elastic deformation, during dropout, be applied to the impact that application force on trip push button is not subject to pin thread pulling force, promote safety belt lock catch reliability and safety.

The utility model is rational in infrastructure, not affected by harness tension, esy to use, safe and reliable.
