Abstract
The utility model relates to a quick connector, in particular to a torque-transmission type easy-detachment quick connector, aiming to solve problems that fixtures for drill pipe detachment in the prior art are heavy and expensive and low in detachment efficiency. The torque-transmission type easy-detachment quick connector comprises a first joint, a second joint and an elastic pin. A thread is arranged on the outer side of the upper portion of the first joint, a first elastic pin through hole is arranged on the outer side wall of the lower portion of the first joint, a thread is arranged on the outer side wall of the lower portion of the second joint, a second elastic pin through hole is arranged on the outer side wall of the upper portion of the second joint, and a deep mounting groove is formed in the middle of the upper end face of the second joint. Further, the deep mounting groove is communicated with the second elastic pin through hole, the lower end of the first joint is inserted in the deep mounting groove, the center line of the first elastic pin through hole and the center line of the second elastic pin through hole coincide, and the elastic pin penetrates the first elastic pin through hole and the second elastic pin through hole sequentially. The quick connector is used for the field of coal mine drilling.
Description
Technical field
The utility model relates to a kind of Quick Connect Kit, is specifically related to the quick detachable Quick Connect Kit of a kind of power transmission.
Background technology
Under coal mine, in drilling process, adjacent two drilling rods are realized and being connected by the screwed short circuit head in two ends.When rig carries out feeding operation, between drilling rod and short circuit head, produce moment of torsion, moment of torsion is larger, being threaded between drilling rod and short circuit head is tightr, very difficult while causing drilling rod dismounting, and the clamper weight of dismounting drilling rod is large, cost is higher, and removal efficiency is lower.
Utility model content
The utility model is for the clamper weight of the existing drilling rod dismounting of solution use is large, cost is higher, and the lower problem of removal efficiency, and then proposes the quick detachable Quick Connect Kit of a kind of power transmission.
The utility model is to address the above problem the technical scheme of taking to be: the utility model comprises the first joint and the second joint, the outside on the first joint top is provided with screw thread, the lateral wall of the second joint bottom is provided with screw thread, the middle part of the second upper end of joint face has installation deep trouth, the bottom of the first joint is that cross section is orthohexagonal cylinder, the regular hexagon that is shaped as of deep trouth notch is installed, and the lower end of the first joint is inserted into installs in deep trouth.
The beneficial effects of the utility model are: the utility model is simple in structure, easy accessibility, and weight is little, and staff can disassemble drilling rod easily and fast, has improved dismounting efficiency, has alleviated staff's labour intensity.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model, and Fig. 2 is the main sectional view of the first joint, and Fig. 3 is that in Fig. 2, A-A is to sectional view, and Fig. 4 is the second joint front view, and Fig. 5 is the left sectional view of Fig. 4, and Fig. 6 is the top view of Fig. 4.
The specific embodiment
The specific embodiment one: present embodiment is described in conjunction with Fig. 1 to Fig. 6, described in present embodiment, the quick detachable Quick Connect Kit of a kind of power transmission comprises the first joint 1 and the second joint 2, the outside on the first joint 1 top is provided with screw thread, the lateral wall of the second joint 2 bottoms is provided with screw thread, the middle part of the second joint 2 upper surfaces has installs deep trouth 2-2, the bottom of the first joint 1 is that cross section is orthohexagonal cylinder, the regular hexagon that is shaped as of deep trouth 2-2 notch is installed, and the lower end of the first joint 1 is inserted into installs in deep trouth 2-2.
The specific embodiment two: present embodiment is described in conjunction with Fig. 3 and Fig. 6, described in present embodiment, the quick detachable Quick Connect Kit of a kind of power transmission also comprises resilient key 3, the lateral wall of the first joint 1 bottom is provided with the first resilient key through hole 1-1, the lateral wall on the second joint 2 tops is provided with the second resilient key through hole 2-1, and deep trouth 2-2 is installed to be communicated with the second resilient key through hole 2-1, after the lower end of the first joint 1 is inserted into and installs in deep trouth 2-2, the center line of the first resilient key through hole 1-1 overlaps with the center line of the second resilient key through hole 2-1, resilient key 3 is successively through the first resilient key through hole 1-1 and the second resilient key through hole 2-1.Other composition and annexation are identical with the specific embodiment one.
Operating principle
When the utility model is used, the top of the first joint 1 is connected with a drilling rod, the bottom of the second joint 2 is connected with another drilling rod, the bottom of the first joint 1 is inserted into and is installed in deep trouth 2-2, resilient key 3 is passed to the first resilient key through hole 1-1 and the second resilient key through hole 2-1, complete the connection of two drilling rods, during work, the regular hexagon cylinder of the first joint 1 bottom and regular hexagon are installed the deep trouth 2-2 transmitting torque that cooperatively interacts, when needs dismounting drilling rod, only resilient key 3 need be taken out, can realize the dismounting of drilling rod.
