Description
Technical Field
The utility model belongs to the technical field of connecting pieces, and particularly relates to a quick locking device.
Background
Because the rolling mill body and the rolling mill base are fixed by the common loose joint bolts in the early stage, only the manual knocking and locking can be carried out, after the rolling mill is used on line, loose joint bolts still exist, the original loose joint bolt structure is adopted, the bolts are loose due to vibration of the loose joint bolts in the rolling process, staff is easy to place in an unsafe environment, the thread loosening process is also easy to ignore when the staff is in a hurry, the jackscrew is directly broken, the locking of the rolling mill is affected, and the labor intensity is increased when production errors are delayed.
Disclosure of utility model
The present utility model provides a quick locking device that addresses the above-identified problems;
in order to solve the problems, the utility model adopts the following technical scheme:
The utility model provides a quick locking device, includes outer hexagonal pole, outer hexagonal pole one side has outer jar body through fixed interior angle bolted connection, outer hexagonal pole and the inside spring that is provided with of outer jar body, outer jar body one side threaded connection has the loose joint screw rod, the inside hydraulic oil that stores of outer jar body.
Preferably, a connecting hole is formed in one side of the loose-joint screw.
Preferably, a sealing ring is arranged at the joint of the outer cylinder body and the outer hexagonal rod.
Preferably, the top end of the loose-joint screw is arranged to be hexagonal.
Compared with the prior art, the utility model has the beneficial effects that:
The locking device is designed by using the hydraulic cylinder principle, comprises a simple hexagonal adjusting and locking device, is provided with an adjusting spring inside and is used for pressure relief and locking, is a quick locking device which is more convenient and quick, improves the working efficiency of staff and improves the working environment of staff, and is used for improving the production efficiency and the product quality of the production line stability of the metallurgical steel rolling industry.
Drawings
The accompanying drawings, which are included to provide a further understanding of the utility model and are incorporated in and constitute a part of this specification, illustrate embodiments of the utility model and together with the description serve to explain the utility model. In the drawings:
FIG. 1 is a diagram of a finishing block of the present utility model;
fig. 2 is a schematic view of the internal structure of the outer cylinder of the present utility model.
In the figure, a-1 and an outer hexagonal rod; 2. an inner and an outer wire sleeves; 3. a piston rod; 4. fixing an inner angle bolt; 5. a spring; 6. an outer cylinder; 7. a loose joint screw; 8. a connection hole; 9. a push rod; 10. a seal ring;
Detailed Description
It should be noted that, without conflict, the embodiments of the present application and features of the embodiments may be combined with each other.
In order that those skilled in the art will better understand the present application, a technical solution in the embodiments of the present application will be clearly and completely described below, and it is apparent that the described embodiments are only some embodiments of the present application, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the present application without making any inventive effort, shall fall within the scope of the present application.
As in fig. 1.2, a quick locking device, including outer hexagonal pole 1, outer hexagonal pole 1 one side is connected with outer cylinder 6 through fixed interior angle bolt 4, outer hexagonal pole 1 is provided with spring 5 with outer cylinder 6 inside, outer cylinder 1 one side threaded connection has loose joint screw rod 7, outer cylinder 6 inside stores has hydraulic oil.
Preferably, a connecting hole is formed on one side of the loose-joint screw 7.
Preferably, a sealing ring is arranged at the joint of the outer cylinder body 6 and the outer hexagonal rod 1.
Preferably, the top end of the loose-joint screw 7 is arranged to be hexagonal.
The working principle of the utility model is that the piston screw rod 7 passes through a hole needing a fastener, then a pin is inserted into the connecting hole 8, the outer hexagonal rod 1 is screwed down, and meanwhile, the spring 5 pressurizes the outer cylinder body 6, so that hydraulic oil pressurizes and locks the inner piston rod 3 to achieve the purpose of fastening.
The above description is only of the preferred embodiments of the present utility model and is not intended to limit the present utility model, but various modifications and variations can be made to the present utility model by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model should be included in the protection scope of the present utility model.
