Pit is connected by the second bolt with the other side of spiral case door.
The position that the inside of the double end connection sleeve is matched with the first adjusting screw rod and the second adjusting screw rod is machined with
Oppositely oriented trapezoidal thread, center is machined with annular escape inside it, is machined with through-hole on annular escape.
It is set with the first locking nut on first adjusting screw rod, and is locked on double end connection sleeve, it is described
It is set with the second locking nut on second adjusting screw rod, and is locked on double end connection sleeve.
The double end connection sleeve, the first adjusting screw rod and the second adjusting screw rod are all made of stainless steel material and are made.
The utility model has the advantages that:
1, by using the C-type clamp structure of the utility model, effectively spiral case door can be reinforced, avoided because of bolt
It is broken, spiral case door caused by water impact etc. is opened suddenly, and there is lock nut locking two kinds of locking sides are connected with threaded hole
Formula, it is easy to loading and unloading, secured, greatly reduce the possibility of C-type clamp loosening.
2, this two-way C-type clamp is using simply, and sound construction, according to the size of live spiral case door, two-way C-type clamp head can add
Work is at different sizes, different hole sizes；If spiral case door threaded hole blocks, threaded hole can also be connected without using bolt
It connects, is directly locked using lock nut.
3, can cooperate simultaneously with the first adjusting screw rod and the second adjusting screw rod by using double end connection sleeve, Jin Ertong
It crosses screw-driven cooperation to hold out against two adjusting screw rods, and then the first C-type clamp and the second C-type clamp is pushed up with spiral case door simultaneously
Tight fit, installation process is simple, easy to use.
Detailed description of the invention
The utility model is described in further detail with reference to the accompanying drawings and examples.
Fig. 1 is overall structure diagram in the utility model use process.
Fig. 2 is the main view of the two-way C-type clamp of the utility model.
Fig. 3 is the left cross-sectional view of the two-way C-type clamp of the utility model.
In figure: spiral case door 1, the first bolt 2, the first C-type clamp 3, the first adjusting screw rod 4, the first locking nut 5, double end connect
Female connector cylinder 6, the second locking nut 7, the second adjusting screw rod 8, the second C-type clamp 9, the second bolt 10, the first threaded hole 11, annular are moved back
Cutter groove 12, through-hole 13, the second threaded hole 14.
Specific embodiment
The embodiments of the present invention is described further with reference to the accompanying drawing.
Fig. 1-3 is please referred to, a kind of dedicated two-way C-type clamp of spiral case door locking, it includes double end connection sleeve 6, the double end
The both ends for connecting sleeve 6 are set with the first adjusting screw rod 4 and the second adjusting screw rod 8 by screw-driven respectively, and described first is adjusted
The end of screw rod 4 is provided with the first C-type clamp 3, and the end of second adjusting screw rod 8 is provided with the second C-type clamp 9, the first C
It is machined with perforative first threaded hole 11 on type folder 3, perforative second threaded hole 14 is machined in second C-type clamp 9, it is described
First threaded hole 11 is connected by the first bolt 2 with the side of spiral case door 1, second threaded hole 14 pass through the second bolt 10 and
The other side of spiral case door 1 is connected.By using above-mentioned two-way C-type clamp, in use, by the first C-type clamp 3 and the 2nd C
