Abstract
The utility model relates to a locking head of an internal contracting brake wheel hub lock for preventing autolocking, which mainly solves the problem of easy automatic locking after the locking of a traditional lock cylinder of the internal contracting brake wheel hub lock fails. The locking head of the internal contracting brake wheel hub lock for preventing autolocking is characterized in that a lock pin (3) and a spiral pushing sleeve (4) are clipped and can move relative to the axial direction, a first spring (5) is placed in the spiral pushing sleeve (4), two ends of the first spring (5) are respectively in contact with the lock pin (3) and a lock cylinder (2), a second spring (6) is sleeved on the lock pin (3), two ends of the second spring (6) are respectively in contact with a lock body (1) and the spiral pushing sleeve (4), and the elasticity of the second spring (6) is more than that of the first spring (5); two strip-shaped spiral grooves (7) are arranged on the spiral pushing sleeve (4), a locking shaft (8) is arranged on the lock cylinder (2), and two ends of the locking shaft (8) are respectively placed in the two strip-shaped spiral grooves (7). After the locking of the lock cylinder fails, the lock pin is always in the movement trend contracting inside the lock body and the locking head does not automatically extend to lock the wheel hub. The locking head has the characteristics of simple structure and safety and reliability.
Description
Technical field:
The utility model relates to a kind of lockset, is specifically related to a kind of anti-self-locking band-type brake hublock tapered end.
Background technology:
The band-type brake hublock is the special lockset that is used on the two-wheeled vehicles such as light motorcycle, electric bicycle, mainly plays antitheft effect, because its compact conformation, easy to use, thereby on two-wheeled vehicle, be widely adopted.At present, the structure of band-type brake hublock mainly promotes cover by lock body, lock core, lock pin, spiral and spring is formed, lock pin, spiral promote cover and lock core is installed in the lock body successively, lock pin and spiral promote cover and fix, and spring places spiral to promote between cover and the lock core, and lock core is provided with bearing pin, the sidewall that spiral promotes cover is provided with helicoid, bearing pin is stuck on the helicoid, and rotary locking cylinder can spur spiral and promote cover and lock pin withdrawal, and lock pin has the trend of stretching out all the time under the effect of spring force.When car travels, in case the lock core lockout failure, owing to reasons such as vibrating, jolt, lock core rotates to the direction of locking lock pin under the effect of spring force, and lock pin can pop and block the band-type brake wheel hub, causes car to stop suddenly, cause personal injury or contingency, have potential safety hazard.
The utility model content:
In order to overcome the deficiency of easily pinning automatically after the existing band-type brake hublock lock core lockout failure, the utility model provides a kind of anti-self-locking band-type brake hublock tapered end, this tapered end lock pin after the lock core lockout failure is in the movement tendency of indentation in lock body all the time, can not stretch out the pinning wheel hub automatically, have simple in structure and safe and reliable characteristics.
The technical solution of the utility model is: a kind of anti-self-locking band-type brake hublock tapered end comprises that lock body, lock core, lock pin, spiral promote the cover and first spring, lock pin, spiral promote cover and lock core is installed on lock body successively, lock pin promotes cover with spiral and blocks also mutually and can move to axial, first spring places spiral to promote in the cover and its two ends contact with lock pin and lock core respectively, be with second spring on the lock pin, the two ends of second spring promote cover with lock body and spiral respectively and contact, and the elastic force of second spring is greater than the elastic force of first spring; Spiral promotes to put to be provided with 2 bar shaped helicla flutes, and lock core is provided with lock shaft, and the two ends of lock shaft place respectively in 2 helicla flutes.
The utlity model has following beneficial effect: owing to take such scheme, spiral promotes to be enclosed within the effect of second spring trend of indentation in the oriented all the time lock body, make lock core to the trend of unblanking the direction rotation, make lock pin be in the movement tendency of indentation in lock body all the time to the greatest extent.When two-wheeled vehicle just in the process of moving, in case the lock core lockout failure, lock pin can not stretch out the pinning wheel hub automatically, and is simple in structure, safe and reliable.
Description of drawings:
Accompanying drawing 1 is a structure sectional view of the present utility model;
Accompanying drawing 2 is structural representations that spiral promotes cover 4 among Fig. 1;
Accompanying drawing 3 is left views of Fig. 2.
1-lock body among the figure, the 2-lock core, the 3-lock pin, the 4-spiral promotes cover, 5-first spring, 6-second spring, 7-helicla flute, 8-lock shaft.
The specific embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
By Fig. 1 in conjunction with Fig. 2 and shown in Figure 3, a kind of anti-self-locking band-type brake hublock tapered end comprises that lock body 1, lock core 2, lock pin 3, spiral promote cover 4 and first spring 5, lock pin 3, spiral promote cover 4 and lock core 2 is installed on lock body 1 successively, lock pin 3 promotes cover 4 with spiral and blocks also mutually and can move to axial, first spring 5 places spiral to promote in the cover 4 and its two ends contact with lock pin 3 and lock core 2 respectively, be with second spring 6 on the lock pin 3, the two ends of second spring 6 promote cover 4 with lock body 1 and spiral respectively and contact, and the elastic force of second spring 6 is greater than the elastic force of first spring 5; Spiral promotes cover 4 and is provided with 2 bar shaped helicla flutes 7, and lock core 2 is provided with lock shaft 8, and the two ends of lock shaft 8 place respectively in 2 helicla flutes 7.Spiral promotes cover 4 trend of indentation oriented all the time lock body 1 under the effect of second spring 6, makes lock core 2 to the trend of unblanking the direction rotation, uses up and makes lock pin 3 be in the movement tendency of indentation in lock body 1 all the time.When two-wheeled vehicle just in the process of moving, in case lock core 2 lockout failure, lock pin 3 can not stretch out the pinning wheel hub automatically, and is simple in structure, safe and reliable.
