A kind of safe restraint device of people of taking advantage of
[technical field]
The present invention relates to a kind of recreation facility, is to take advantage of the safe restraint device of people specifically.
[background technology]
Recreation facility, according to the difference of performance, the method for operation, speed and the structure thereof of equipment, must arrange corresponding restraint device.Restraint device commonly used has safety belt, safety Crowbar Pressing, pin etc.Safety belt generally can be opened by passenger oneself, is commonly used for auxiliary restraint device.Safety Crowbar Pressing commonly used can adjusting elasticity, and the governor motion operated by rotary motion is in seat, and weight and required installing space are larger.Simple pin is lighter, but, due to unadjustable, lock between rear restraint device and passenger larger gap is often arranged, and can not well play the effect of constraint.
the patent No. is ZL201020505930.X, name is called in a kind of patent of invention of safety seat and discloses a kind of safe restraint device, this safe restraint device has adopted rotational structure to carry out unidirectional adjusting, the ratchet that is hinged its end of rectilinear motion drive of pull bar rotates, thereby control, rotate ratchet and gear engagement, gear rotates band carry-over bar single-way moving, realize adjustable range, said structure has following shortcoming: parts are many, transmission progression is many, being input to the rail plate single-way moving and will passing through a plurality of revolute pairs from control action, articulated structure is many, lubricated constant easily stuck.
[summary of the invention]
The present invention seeks to have overcome deficiency of the prior art and provide a kind of simple in structure, transmission progression is few, is not easy the stuck safe restraint device of people of taking advantage of.
In order to solve the technical problem of above-mentioned existence, the present invention adopts following technical proposal:

[specific embodiment]
Below in conjunction with accompanying drawing, describe the present invention:
A kind of safe restraint device of people of taking advantage of comprises and is contained in seat 1 front end be used to stopping the pin 2 of taking advantage of the people that a side of pin 2 one ends and seat 1 is hinged, and the other end of pin 2 is locked in the opposite side of seat 1 by pin.
The guide-rail plate 4 that is provided with guide frame 3 at pin 2 middle parts and can only forward and backward movement under guide frame 3 guide effects, a side at guide-rail plate 4 is provided with ratchet bar 5, on pin 2, also be provided with pull bar 8, at pull bar 8 one ends, be provided with its movable ratchet 6 that horizontally slips relatively, after between movable ratchet 6 and pin 2, being provided with driving activity ratchet 6 and moving with the pawl restoring spring 7 of ratchet bar 5 engagements; On seat 1, be provided with and can touch and limit pull bar 8 mobile block 10 to the right with pull bar 8 other ends, between pull bar 8 other ends and pin 2, be provided with and can drive pull bar 8 to the pull bar back-moving spring 9 that pulls movable ratchet 6, makes movable ratchet 6 separate with ratchet bar 5 away from ratchet bar 5 directions.
In use, first the pin lock is opened, rotate afterwards pin 2, because block 10 separates with pull bar 8, under the effect of pull bar back-moving spring 9, pin 2 move right and thus sour jujube movable claw 6 break away from ratchet bar 5 fully, in movable ratchet 6 is pulled away to the stroke of working region, the elastic force of pull bar back-moving spring 9 is all the time greater than the elastic force of pawl restoring spring 7, thereby makes movable ratchet 6 be pulled away from smoothly working region.Then the people is sitting on seat 1, rotate again pin 2, the pin lock is locked in pin 2 on seat 1, due to block 10, with pull bar 8 pressures, touching and push up presses it to be moved to the left, pull bar back-moving spring 9 is compressed, after pull bar 8 tops were pressed onto to position, pawl restoring spring 7 driving activity ratchets 6 were moved to the left and ratchet bar 5 engagements.Due to coordinating of movable ratchet 6 and ratchet bar 5, make guide-rail plate 4 unidirectionally to move inwards, that is to say unmarried governor motion, thereby guide-rail plate 4 can only be pulled inward.Can be according to people's body size, pull with hand the unidirectional plate of sliding guides inwards 4, ratchet bar 5 promotion activity ratchets 6 move to the right, adjust the backrest of seat 1 and the distance between guide-rail plate 4, apart from adjusting rear pawl restoring spring 7 driving activity ratchets 6, be moved to the left with ratchet bar 5 engagements and position, in the process of unidirectional adjustment distance, pull bar 8 remains motionless, so just mix up the travel distance that is suitable for taking advantage of people's bodily form size, made the people both sit comfortablely, guaranteed again safety.
In order to make pull bar 8 more stable in moving left and right process, at described pull bar 8 other ends, also be connected with guide post 81, in pin 2, be provided with the guiding slide opening 21 that inserts and can horizontally slip for guide post 81, described guide post 81 other ends and described block 10 touch.
Optimal way as the present embodiment, on described pull bar 8, be fixed with connecting ring 82, on pin 2, be provided with the first gear hole 22 relative with connecting ring 82, described guide post 81 1 ends pass connecting ring 82, the first gear hole 22 in turn, described pull bar back-moving spring 9 is stage clip, it is enclosed within guide post 81 outsides and is arranged between connecting ring 82, the first gear hole 22, and guide post 81 middle parts are provided with the step 811 that is stuck in connecting ring 82 other ends, and guide post 81 other ends stretch in guiding slide opening 21.
The concrete installation of described movable ratchet 6 is as follows: on pin 2, be provided with ratchet slide guide hole 23 and the second gear hole 24, described movable ratchet 6 heads pass ratchet slide guide hole 23, movable ratchet 6 afterbodys pass the second gear hole 24, described pawl restoring spring 7 is enclosed within on movable ratchet 6, bear down on one and be pressed on movable ratchet 6 in pawl restoring spring 7 one end tops, pawl restoring spring 7 one ends withstand on the second gear hole 24 walls.
Movable ratchet 6 is as follows with the optimal way that pull bar 8 is connected: at movable ratchet 6 afterbodys, be provided with strip through-hole 61, on pull bar 8, be provided with the crotch section 83 that can extend in strip through-hole 61, the width of crotch section 83 is less than strip through-hole 61 width.Movable ratchet 6 closes with pull bar 8: when movable ratchet 6 meshed fully with ratchet bar 5, crotch section 83 leaned against on the hole wall on strip through-hole 61 right sides, so that pull bar 8 can pull open movable ratchet during rollback to the right fast.Due to the width of crotch section 83 less than strip through-hole 61 width, between the left side hole wall of all strip through-holes 61 and crotch section 83, suitable distance is arranged, when movable ratchet, on the ratchet bar face, make relative sliding and produce rollback when motion, crotch section 83 can not limit the ratchet stroke.
Described guide frame 3 includes and is located at two on pin 2 row leading block 31, and described guide-rail plate 4 is arranged between two row's leading blocks 31, and leading block 31 is corresponding touches with two rows respectively for the left and right sidewall of guide-rail plate 4.On described guide-rail plate 4 left and right sides walls, be respectively equipped with gathering sill 41, described leading block 31 is placed in gathering sill 41.
As the optimal way of the present embodiment, on pin 2, also be provided with and drive the guide rail back-moving spring 20 that guide-rail plate 4 resets.Like this, after movable ratchet 6 breaks away from ratchet bars 5, guide-rail plate 4 under the effect of guide rail back-moving spring 20, guide-rail plate 4 Rapid resets.
