Embodiment
The present invention is described in detail below in conjunction with accompanying drawing.
As shown in figs 1 to 6, the present embodiment provides a kind of swing arm 500 braking wheel safety hook, including base 100 and sets
Put on base 100 and the guide rail that can slide up and down, swing arm 500 braking wheel safety hook also include brake 300, swing arm 500,
First locating shaft 200 and the second locating shaft 400, brake 300 are provided with positioning hole, and locating shaft is located in positioning hole, brake
300 are rotatably arranged in base 100 by locating shaft, and swing arm 500 is rotatably fixed on bottom by the second locating shaft 400
On seat 100；Brake 300 has multiple to the triggering tooth extended away from the direction of the first locating shaft 200；Swing arm 500 includes difference
Trigger unit and lock part positioned at the both sides of the second locating shaft 400, when guide rail is slided up and down, trigger unit is according to the work of self gravitation
With lower with triggering tooth contact；When guide rail falls, triggering tooth driving swing arm 500 is rotated, and triggering tooth is connected to lock part, is matched somebody with somebody
Close locking guide rail.
Specifically, as shown in figure 1, base 100 is hollow cube structure in the present apparatus, brake 300 passes through first
Locating shaft 200 is arranged on the inside of base 100, and brake 300 can be rotated around the first locating shaft 200, and swing arm 500 is located at system
The oblique upper position of dynamic device 300, swing arm 500 is fixed on inside base 100 by the second locating shaft 400, and the middle part of swing arm 500 has
Positioning hole, the second locating shaft 400 is inserted in the positioning hole of swing arm 500.Guide rail in the present embodiment includes two Hes of montant 710
Multiple cross bars 720 between two montants 710.Have in a side of base 100 as leading to that guide rail is moved up and down
Road, the direction that guide rail is moved up and down can be limited by enclosing the base 100 of the passage, prevent guide rail from swinging.
As shown in Fig. 2 the trigger unit of swing arm 500 is the right part of swing arm 500 in figure, lock part is a left side for swing arm 500
Side part, the weight of trigger unit is more than the weight of lock part so that trigger unit has the inclination let droop.In guide rail downward actuation
When, the tooth top 320 of brake 300 streaks trigger unit, and next triggering tooth streaks lock part during this period and both do not do
Relate to.The figure of a, b, c tri- illustrates guide rail brake 300 and the mutual position relationship of swing arm 500 during normal decline in Fig. 3.
During guide rail is moved up, c, b, a mistake in brake 300 and the mutual position relationship of swing arm 500 such as Fig. 3
Journey.
When being fallen such as guide rail, guide rail drives the quick rotation of brake 300 so that the triggering tooth of brake 300 hits swing arm
500 trigger unit, trigger unit is quickly rotated up immediately, and corresponding lock part correspondence is quickly rotated down, in the return of swing arm 500
Before, next triggering tooth is squeezed in the back of lock part, forms effect as shown in Figure 4.It should be understood that in order to prevent swing arm
500 excessively swing, and have the locking system that limitation Baidu excessively swings in the top of triggering tooth.
As shown in figure 5, brake 300 includes the main body of tubulose brake 300 and on the main body ring surface of brake 300
Multiple triggering teeth, triggering tooth position be angularly uniformly distributed along ring surface.Triggering tooth is straight-tooth shape, and triggers the tooth top of tooth
320 arcwall face to seamlessly transit.Brake 300 is star topology, and the middle part of brake 300 is to penetrate the both ends of the surface of brake 300
Through hole, the first locating shaft 200 is inserted into the through hole, and the middle part of brake 300 is tubulose, has 5 in the periphery of tubular portion
Individual triggering tooth, and five triggering teeth, in same plane of rotation, each triggering tooth includes the side wall 310 (tooth wall) and tooth of two straight lines
Top 320 is the arcwall faces that seamlessly transit, that is, causes the triggering tooth more smooth trigger unit for crossing swing arm 500.
As described in Figure 6, swing arm 500 is arc.The part of trigger unit and triggering tooth contact is the arcwall face seamlessly transitted.Tool
Body is, during guide rail decline, and the tooth top 320 for triggering tooth is slided by crossing second connecting portion 522 by the first wall 521 of triggering
Enter the second wall 523 of triggering, in guide rail uphill process, the tooth top 320 for triggering tooth reversely crosses the second company by triggering the second wall 523
Socket part 522 slides into the first wall 521 of triggering, in the process, and the lower surface of trigger unit connects with triggering the tooth top 320 of tooth all the time
Touch, while will not interfere with the movement of next triggering tooth on the direction of rotation of brake 300 in lock part.Next triggering tooth
The second wall of locking 513 is slided into by first connecting portion 512.Stopping means on trigger unit movement locus is block 800.
When quickly being fallen such as guide rail, triggering tooth hits the first wall 521 of triggering, lock part rapid decrease so that in brake
Next triggering tooth in 300 rotation directions is locked at the first wall of locking 511, forms lockup state.It should be understood that triggering
The rotary motion trace scope of tooth tooth top 320 is more than the hunting range of swing arm 500.
The stopping means that limitation swing arm 500 swings extreme position is respectively provided with above trigger unit and lock part.Such as Fig. 2 institutes
Show, in the present embodiment, the stopping means of lock part is the gag lever post 600 through base 100, and it plays a part of being to prevent locking
Portion position excess enthalpy is top, while the position of correspondence limitation trigger unit.In the present embodiment, first stopping means is bottom above trigger unit
Stopping means above the roof of seat 100, lock part is the gag lever post 600 between the grip block of position two.
Base 100 is to include two grip blocks of chute and the place that extended sideways along chute for accommodating guide rail, brake
300 and swing arm 500 be located between two grip blocks.Base 100 encloses the passage slided for guide rail simultaneously, it is to avoid it shakes
It is dynamic.
Above content is only presently preferred embodiments of the present invention, for one of ordinary skill in the art, according to the present invention's
Thought, in specific embodiments and applications can be so that many changes may be made, as long as these changes are without departing from the structure of the present invention
Think, belong to protection scope of the present invention.
