Drilling rod coupling bar stopping device of the present utility model is after shank 1 is interspersed in pin-and-hole, under external force, by pin
Body 1 is interspersed with from armful spring 22, and lock part 2 is connected on drilling rod, is embraced spring 22 to the position locking of shank 1, just can be realized and be connected
The connection of fitting, its installing/dismounting step is simple, improves installation effectiveness, and long lifespan, it is adaptable to the occasion frequently assembled and disassembled.
The drilling rod of the present embodiment, is respectively equipped with corresponding pin-and-hole 9, the body of rod 7 on the body of rod 7 and drillstock 8 as shown in Figure 3
Connected with drillstock 8 by above-mentioned drilling rod coupling bar stopping device.In order to improve installation effectiveness, installation steps are reduced, lock part 2 is set
Put on the shank 1 for exposing drill rod body 7 in shank 7, specifically, being arranged on the outside of pin-and-hole 9.
One drillstock 8 is to be used to connect two bodies of rod 7, and the two ends of drillstock 8 are respectively provided with a plug 81 and insert adjacent two respectively
In individual drilling rod 7, connected respectively by two insertings of shank 1, be so contiguously formed borer drill rod, such a drilling rod is that have center to lead to
Hole, the through hole through supercooled water is sealed between the body of rod 7 and drillstock 8 by rubber ring.
For jack of at least one end provided with four directions of the body of rod 7, drillstock 8 is provided with matched cubic plug, and bar
The drilling rod of body 7 and the inside of drillstock 8 provided with the limbers run through, the lateral surface by the axis of pin-and-hole 9 and cubic jack is in 45 ° of angles
Set, i.e., pin-and-hole 9 is through the two neighboring face of the body of rod 7 and drillstock 8, the axis of such pin-and-hole 9 and the inwall side of body of rod square hole
In 45 °, with the lateral surface of drillstock 8 in 45 °.So can with and avoid shank 1 pass through limbers, fundamentally prevented water flowing brill
The possibility of bar leak.
In order to add the shear behavior of shank 1, while being easy to the dismounting of shank 1, in the above-mentioned drilling rod with limbers
On the basis of, monosymmetric in cubic jack is provided with pin-and-hole 9, and monosymmetric in cubic plug is provided with pin-and-hole 9, will embrace
Spring 22 is located therein on the shank 1 in the outside of a pin-and-hole 9, shank 1 is set to skim to the U-shaped pin of mouth, the bending arc of U-shaped pin is with regard to structure
Into latch functions together to shank 1, skim mouth and be shaped such that shank 1 is deformed upon during inserting and blocked as pin-and-hole
In, it is formed a latch functions.Because shearing resistance section adds one times, shear behavior is lifted at double, while U-shaped dismantling
The part for the shank 1 for not embraced the banding of spring 22 is tapped during pin, U-shaped pin is just can be taken off, extremely convenient is dismantled.
Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model
Within the spirit and principle of utility model, any modification, equivalent substitution and improvements made etc. should be included in the utility model
