Abstract
The utility model belongs to the block pin field and particularly relates to a thread-locking block pin. The thread-locking block pin comprises a support lug, a shaft, a pull ring and a spring. The thread-locking block pin is characterized in that: one end of the shaft passes through the support lug and is connected with equipment, and the other end of the shaft is matched with the support lug and is partially located in the support lug. The shaft and the support lug are provided with threads. With the adoption of a thread-locking manner, the thread-locking block pin has the advantages of simpleness in assembly, convenience for machining, cost saving, high security and reliability, and beautiful and elegant appearance.
Description
Technical field
The utility model belongs to the bayonet lock field, relates in particular to a kind of screw-threaded coupling bayonet lock.
Background technique
At present the bayonet lock type has positioning clamping pin and common suspension ring bayonet lock, and magnetic suspension ring bayonet lock and other type bayonet lock generally all are used for hanging of material on the ship, and the moving and the down-hole workover eration of material in the oil well also has the rotation in electronics CD and cartoon production.
The bayonet lock volume is little, and is easy to use, and stationarity is strong.The axle of bayonet lock and pin are two partly to form generally speaking, need processing separately, and when assembling, will sell with axle and all will align, and have relatively high expectations, and use inconvenience, and spool and pin when mobile, be prone to come off.
Summary of the invention
For solving above technical problem; The utility model adopts a kind of screw-threaded coupling bayonet lock, comprises journal stirrup, axle, draw ring and spring, it is characterized in that: axle one end passes journal stirrup and equipment links; The other end cooperates with journal stirrup and part is positioned at journal stirrup, on axle and the journal stirrup screw thread is arranged.
Screw thread on the journal stirrup is positioned at and the axle cooperation place, and the screw thread on the axle is located on the axle in the journal stirrup.
The end that shaft extension is gone into equipment is big with respect to the shaft portion diameter that cooperates with journal stirrup.
On the axle two convexities are arranged, spring one end and convexity link, and spring is played restriction ejection effect.
As the improvement of the utility model, at axle and journal stirrup cooperation place seal ring is housed, seal ring is a rubber seal, prevents sand and dust, rainwater etc. get into journal stirrup even access arrangement thereupon, improve working life.
The utility model has reduced part having replaced pin by the screw thread on the axle aspect the processing, and journal stirrup need not process and be used for the track groove that fitting pin walks, and only needs tapping, can make processing easy, practice thrift cost; Assembling is simple, and the reliability of safety is high, and elegant in appearance, is applicable to numerous areas such as automobile repacking, electric equipment carriage, device fabrication line.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Accompanying drawing 1 is the utility model side schematic view
Accompanying drawing 2 is the utility model assembling schematic representation
Among the figure: 1. the convexity on 9 of screw thread 8 equipment on screw thread 7 journal stirrups on 6 of 3. 4. springs of seal ring 2. journal stirrups, 5. draw rings
Embodiment
The screw-threaded coupling bayonet lock that the utility model adopts comprises journal stirrup 2, axle 3, draw ring 5 and spring 4, and it is characterized in that: 3 one end passes journal stirrup 2 and links with equipment 8, and the other end cooperates with journal stirrup 2 and part is positioned at journal stirrup 2, on axle 3 and the journal stirrup 2 screw thread is arranged.Screw thread 7 on the journal stirrup 2 is positioned at and axle 3 cooperation places, and the screw thread 6 on the axle 3 is located on the axle 3 in the journal stirrup 2.The end that axle 3 stretches into equipment 8 is big with respect to axle 3 section diameters that cooperate with journal stirrup 2.On the axle 3 two convexities 9 are arranged, spring 4 one ends link with protruding 4, and the other end and journal stirrup link, and axle 3 is equipped with seal ring 1 with journal stirrup 2 cooperation places, and seal ring 1 is a rubber seal.
The utility model and equipment 8 are mounted to identical platform, and the installation position selection of the utility model is in the position of or level corresponding with equipment opening or groove.Hole on the equipment 8 is than axle 3 somewhat larger in diameter, and groove width is also than axle 3 somewhat larger in diameter.When equipment 8 needs to move; Pulling draw ring 5, spring 4 is compressed, and draw ring 5 draws motionless when the screw thread on the axle 6 contacts with the screw thread 7 of journal stirrup; This moment draw ring 5 half-turns of not loosing one's grip and turn clockwise; Screw thread 6 on the axle screws in journal stirrup screw thread 7 immediately, and axle 3 leaves equipment 8 and moved by screw thread 7 restrictions of journal stirrup, and this moment can mobile device.Be rotated counterclockwise draw ring 5 when needing limiting device to move again, the screw thread 6 on the axle leaves journal stirrup screw thread 7 rear spring 4 can be pressed into equipment opening or groove with axle 3, gets final product moving of limiting device.
