Abstract
The utility model relates to a locking device with adjustable locking force. The locking device comprises a limiting pin pass, a nut, a spring, a pin and a sleeve. One end of the spring is abutted to the limiting pin pass; the other end of the spring is abutted to the nut; the nut is connected with the pin in a threaded manner; two ends of the limiting pin pass are of U-shaped structural parts each having a through hole; the pin penetrating the through holes is movably connected with the limiting pin pass. The bottom of the handle is nested in the sleeve. A bottom threaded portion of the pin is screwed in the sleeve and abutted to the handle. The locking device has the advantages that the handle can function in limiting to avoid separating or shifting of the handle, caused in the operating or carrying process; the locking device is simple in structure and convenient to use, pre-tightening force of the spring can be optionally adjusted through the nut, practicality and operability are greatly improved, locking degree can be controlled more conveniently, and work efficiency is improved.
Description
Technical field
The utility model relates to a kind of latching device of locking-adjustable power.
Background technology
The handle of oil recovery gas production derrick hand winch is fixed near derrick place hand winch, because the phenomenon that handle comes off often appears in vibration, causes industrial accident, and handle come off after because circumstance complication is difficult to foundly, to production, make troubles.
Summary of the invention
For overcoming the deficiencies in the prior art, the purpose of this utility model is to provide a kind of latching device of locking-adjustable power, avoids handle to come off.
For achieving the above object, the utility model is achieved through the following technical solutions:
A kind of latching device of locking-adjustable power, comprise locating dowel pin road, nut, spring, pin rod, sleeve pipe, spring one end is resisted against on locating dowel pin road, the other end is resisted against on nut, nut and pin rod are threaded connection, described locating dowel pin road is the U-shaped framing member that two ends are provided with through hole, and pin rod is flexibly connected with locating dowel pin road through through hole; Handle bottom is socketed in sleeve pipe, and the threaded portion of pin rod bottom screws in sleeve pipe, is resisted against on handle.
Between described spring and nut, be provided with pad.
Described pin rod is L shaped structure.
Compared with prior art, the beneficial effects of the utility model are:
Handle is because the vibration of work or handling process generation causes the phenomenon that comes off or be shifted, and this device can play spacing effect to handle, avoids handle to come off.Have simple in structure, easy to usely, the predetermincd tension of spring can arbitrarily regulate by nut, has greatly increased practicality and operability, and degree that can convenient control locking, has improved work efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is working state figure of the present utility model.
Fig. 3 is the cutaway view of Fig. 2.
In figure: 1-pin rod 2-locating dowel pin road 3-spring 4-pad 5-nut 6-handle 7-sleeve pipe.
The specific embodiment
Below in conjunction with Figure of description, the utility model is described in detail, but should be noted that enforcement of the present utility model is not limited to following embodiment.
See Fig. 1-Fig. 3, a kind of latching device of locking-adjustable power, comprise locating dowel pin road 2, nut 5, spring 3, pin rod 1, spring 3 one end are resisted against on locating dowel pin road 2, the other end is resisted against on nut 5, nut 5 is threaded connection with pin rod 1, and described locating dowel pin road 2 is provided with the U-shaped framing member of through hole for two ends, and pin rod 1 passes through hole and is flexibly connected with locating dowel pin road 2.Between spring 3 and nut 5, be provided with pad 4.Pin rod 1 is L shaped structure.
Because handle 6 bottoms are socketed in sleeve pipe 7, and the threaded portion of pin rod 1 bottom screws in sleeve pipe 7, is resisted against on handle 6, and handle 6 is played to position-limiting action.
The utility model handle is because the vibration of work or handling process generation causes the phenomenon that comes off or be shifted, and this device can play spacing effect to handle, avoids handle to come off.Have simple in structure, easy to usely, the predetermincd tension of spring can arbitrarily regulate by nut, has greatly increased practicality and operability, and degree that can convenient control locking, has improved work efficiency.
