Abstract
The utility model discloses a limiting lock pin which comprises a drawing part, a fixing part, a spring and a bolt. After the spring sleeves the bolt, the bolt sleeves the fixing part, so that the spring, the bolt and the fixing part are connected together through a thread structure on the fixing part and then are fixedly connected through a middle thread round hole structure on the drawing part and a cylindrical thread structure at the upper end of the bolt. According to the limiting lock pin disclosed by the utility model, a protruding part on the drawing part and a groove structure on the fixing part are enabled to be kept in a certain state, so that the conversion between a pulling-up state and a locking state is realized. The limiting lock pin disclosed by the utility model is simple in structure and reasonable in design, can be automatically positioned or can be manually controlled, and is suitable for fixing and limiting among various parts.
Description
Technical field
The utility model relates to a kind of mechanical connecting element, specifically relates to a kind of spacing lock pin.
Background technique
In productive life, between some parts, usually will use screw is connected and fixed, but when installation and removal, the dismounting of screw is cumbersome, therefore, people utilize lock pin to fix all parts, avoided the operation of tightening together, the flexible lock pin of commonly using in lock pin, current existing flexible lock pin is all automatically to locate according to the elasticity of spring, can not realize manual control, this just causes the defect of some application.
Summary of the invention
The utility model is mainly to solve the existing technical problem of above-mentioned prior art, a kind of spacing lock pin is provided, this spacing lock pin can automatically be located and also can be realized manual control by the elasticity of spring simultaneously, this spacing lock pin comprises drawing part, fixed block, spring and latch, the upper end of drawing part is drawing part rotary component, there is a square drawing part projecting member lower end, there is a drawing part thread cylinder hole centre, the inside, upper end of fixed block is a square fixed block groove, lower end is fixed block thread cylinder structure, fixed block groove on fixed block and the drawing part projecting member on drawing part match, latch upper end is latch thread cylinder structure, lower end is the cylindrical mounting structure of latch, described spring is inserted in after latch, latch is inserted in to fixed block, like this by the fixed block thread cylinder structure on fixed block by spring, latch and fixed block couple together, then by the drawing part thread cylinder hole on drawing part, be fixedly connected with latch upper end latch thread cylinder structure.
During work, drawing part is upwards drawn, because drawing part is threaded connection with latch, so latch also and then moves up, spring is in compressive state, drawing part is moved certain altitude to and is rotated to an angle, the drawing part projecting member on drawing part is stuck in to the upper end of the fixed block groove of fixed block, now the state of lock pin in pull-up; Rotation drawing part, drawing part projecting member on drawing part is aimed to the fixed block groove of fixed block, unclamp drawing part, under the effect of spring force, drawing part and latch move down, when the drawing part projecting member on drawing part contacts with the least significant end of the fixed block groove of fixed block, motion stops, and lock pin is in locking state.
The utility model is simple in structure, reasonable in design, can realize automatic location also can manually control, and is applicable to fixing and spacing between various parts.

Embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: referring to Fig. 1-4, above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of spacing lock pin, comprise drawing part 1, fixed block 2, spring 3 and latch 4, the upper end of drawing part 1 is drawing part rotary component 5, there is a square drawing part projecting member 7 lower end, there is a drawing part thread cylinder hole 6 centre, the inside, upper end of fixed block 2 is a square fixed block groove 8, lower end is fixed block thread cylinder structure 9, fixed block groove 8 on fixed block matches with the drawing part projecting member 7 on drawing part 1, latch 4 upper ends are latch thread cylinder structure 10, lower end is the cylindrical mounting structure 11 of latch, described spring 3 is inserted in after latch 4, latch 4 is inserted in to fixed block 2, like this by the fixed block thread cylinder structure 9 on fixed block 2 by spring 3, latch 4 and fixed block 2 couple together, then by the drawing part thread cylinder hole 6 on drawing part 1, be fixedly connected with latch 4 upper end latch thread cylinder structures 10.
During work, drawing part 1 is upwards drawn, because drawing part 1 is threaded connection with latch 4, so latch 4 also and then moves up, spring 3 is in compressive state, drawing part 1 is moved certain altitude to and is rotated to an angle, the drawing part projecting member 7 on drawing part 1 is stuck in to the upper end of the fixed block groove 8 of fixed block 2, now the state of lock pin in pull-up; Rotation drawing part 1, drawing part projecting member on drawing part 17 is aimed to the fixed block groove 8 of fixed block 2, unclamp drawing part 1, under the effect of spring force, drawing part 1 and latch 4 move down, when the drawing part projecting member 7 on drawing part 1 contacts with the least significant end of the fixed block groove 8 of fixed block 2, motion stops, and lock pin is in locking state.
Finally, it should be pointed out that above embodiment is only the more representational example of the utility model.Obviously, the utility model is not limited to above-described embodiment, can also have many distortion.Any simple modification, equivalent variations and modification that every foundation technical spirit of the present utility model is done above embodiment, all should think and belong to protection domain of the present utility model.
