Abstract
The utility model relates to the field of workover rig guardrails, in particular to a spring bolt. The spring bolt is characterized by comprising a pin cylinder, a bolt body, a spring and a cylinder cap, one end of the bolt cylinder is in threaded connection with the cylinder cap, the bolt body is arranged in the bolt cylinder, the spring is arranged between the bolt body and the bolt cylinder, a hole is arranged at the center of the other end of the bolt cylinder, the size of the hole is matched with the diameter of the bolt body, an opening slot for fixing the bolt body is arranged on the wall of the bolt cylinder, two notches are arranged along the length direction of the opening slot and correspond to a locking position and a retreating position of the bolt body, and a stop piece for stopping the spring is arranged on the bolt body. Compared with the prior art, the spring bolt has the advantages of lightness, difficulty in loss and capabilities of meeting the requirements on convenience in mounting and demounting of the guardrails when a workover rig is in oil field change operation and eliminating hidden dangers of accidents during production due to the fact that workers use tools incapable of meeting requirements for substitution after the bolt is lost, so that safety production is realized.
Description
Technical field
The utility model relates to well repairing machine guardrail installing area, relates in particular to a kind of night bolt.
Background technique
Because well repairing machine through the different oil field operations of being everlasting, when changing the operation oil field, all can be dismantled the well repairing machine accessories such as guardrail at every turn.And the well repairing machine guardrail is for convenient disassembly, generally all adopt bearing pin to fix, but little being easy to of bearing pin volume lost, cause on the one hand unnecessary loss, after bearing pin is lost on the other hand, a lot of workmans use the instrument that does not reach requirement and replace, and have strengthened in the production to occur unexpectedly, for safety in production hides some dangers for.
Summary of the invention
The purpose of this utility model provides a kind of night bolt, and lightweight and portable in volume is difficult for losing, when satisfying well repairing machine replacing oil field operation, and the requirement of guardrail easy installation and removal.
For solving the problems of the technologies described above, the technical solution of the utility model is:
A kind of night bolt, comprise pin cylinder, latch, spring and cylinder cap, pin cylinder one end is connected with the cylinder cap thread, be provided with latch in the pin cylinder, be provided with spring between latch and the pin cylinder, pin cylinder the other end center is porose, hole size and pin diameter coupling, described pin barrel is provided with the opening slot that is used for fixing the latch position, is provided with two place's gap along the length direction of opening slot, the locking position of corresponding latch and withdraw from the position.
Described latch is provided with the catch of gear spring.
Compared with prior art, the beneficial effects of the utility model are: lightweight and portable in volume, be difficult for losing, when satisfying well repairing machine replacing oil field operation, the requirement of guardrail easy installation and removal is eliminated because of after bearing pin loses, and the workman replaces with the instrument that does not reach requirement, the hidden danger that meets accident in causing producing realizes safety in production.

Fig. 2 is the left view of Fig. 1.
Among the figure: the 6-opening slot 7-gap 8-catch of 1-pin cylinder 2-latch 3-spring 4-cylinder cap 5-hole
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described further:
See Fig. 1, Fig. 2, it is a kind of night bolt example structure of the utility model schematic representation, comprise pin cylinder 1, latch 2, spring 3 and cylinder cap 4, pin cylinder 1 one ends are threaded with cylinder cap 4, are provided with latch 2 in the pin cylinder 1, be provided with spring 3 between latch 2 and the pin cylinder 1, pin cylinder 1 the other end center is porose 5, hole 5 sizes and bearing pin 2 diameters coupling, and described pin cylinder 1 wall is provided with the opening slot 6 that is used for fixing the latch position, length direction along opening slot 6 is provided with two place's gap 7, the locking position of corresponding latch and withdraw from the position.
In order to make the stressed of spring 3 evenly prevent that latch from moving deflection, latch 2 is provided with the catch 8 of gear spring.
When the well repairing machine guardrail is installed, get the utility model latch and place connection part, mobile latch makes the handle of latch slip into a locking position gap, and latch can play under the effect of spring, keeps coupled condition; When the well repairing machine guardrail is dismantled, the handle of latch is pulled out by locking position gap, then latch is retracted under the effect of spring and is slipped into locking position gap, latch can be taken out, and realizes easily the dismounting of well repairing machine guardrail.
