[0025] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.
[0026] Example 1
[0027] Reference Figure 1-4 , which is the first embodiment of the utility model, provides an aluminum alloy oil drill pipe that is easy to connect. This aluminum alloy oil drill pipe that is easy to connect includes a first drill pipe 1 and a second drill pipe 2. The surfaces of the first drill pipe 1 and the second drill pipe 2 are both provided with connecting devices 3. The connecting device 3 includes a plurality of support bars 31. The support bar 31 is fixedly connected to the first drill pipe 1. A slider 32 is slidably connected to the inner wall of the support bar 31. A clamping block 33 is fixedly connected to the surface of the slider 32. A plurality of clamping grooves 39 are provided on the inner wall of the second drill pipe 2. The size of the clamping block 33 is adapted to the size of the clamping groove 39 on the inner wall of the second drill pipe 2. A spring 34 is placed inside the clamping block 33. The two ends of the spring 34 are respectively fixedly connected to the clamping block 33 and the support bar 31.
[0028] Example 2
[0029] Reference Figure 2-4 , which is the second embodiment of the utility model, and this embodiment is different from the first embodiment in that:
[0030] The surface of the slider 32 is rotatably connected with a ball 35 , which is a spherical structure.
[0031] A pull rope 36 is fixedly connected to the surface of the clamping block 33 , and sliding grooves are provided inside the support bar 31 and the first drill rod 1 , and the pull rope 36 is located in the sliding grooves inside the support bar 31 and the first rotating rod.
[0032] One end of the pull rope 36 is fixedly connected to an insertion rod 37 , and the insertion rod 37 is threadedly connected to a sliding groove on the surface of the first drill rod 1 .
[0033] A limiting rod 38 is fixedly connected to the surface of the first drill rod 1 , and a locking ball is fixedly connected to one end of the limiting rod 38 .
[0034] During use, the aluminum alloy oil drill pipe is lighter in weight, easier to operate, and has the advantages of high strength and not easy to deform. As the drilling depth increases, when the aluminum alloy oil drill pipe (the aluminum alloy oil drill pipe is the first drill pipe 1 in this application) is connected to the second drill pipe 2, first, the first drill pipe 1 is aligned with the second drill pipe 2, and the support bar 31 on the first drill pipe 1 is pushed into the second drill pipe 2. When the block 33 contacts the edge of the second drill pipe 2, it will be resisted by the second drill pipe 2. At this time, the block 33 is pushed toward the support bar 31 with the help of the slider 32. The support bar 31 is then retracted and the spring 34 is driven to retract. At this time, the support bar 31 can be conveniently inserted into the second drill rod 2. The setting of the ball 35 can effectively reduce the friction between the slider 32 and the support bar 31, making it convenient for the block 33 to slide in the support bar 31. As the support bar 31 moves, the support bar 31 gradually reaches the slot 39 of the second drill rod 2. At this time, the block 33 loses the resistance of the second drill rod 2 and stretches under the action of the elastic force of the spring 34. At this time, the block 33 is stuck in the slot 39 of the second drill rod 2, thereby improving the first The stability between the drill rod 1 and the second drill rod 2 is improved, thereby improving the connection efficiency between the first drill rod 1 and the second drill rod 2. At this time, the plug rod 37 is rotated and inserted into the sliding groove of the first drill rod 1, thereby improving the stability of the plug rod 37 and reducing the situation where the pull rope 36 is pulled due to external factors. When the first drill rod 1 and the second drill rod 2 are separated, the plug rod 37 is taken out of the sliding groove of the first drill rod 1. At this time, the pull rope 36 is pulled, and the pull rope 36 drives the block 33 to move into the support bar 31. At this time, the block 33 and the slot 39 of the second drill rod 2 are connected. The draw rope 36 can be separated from each other, thereby facilitating the disassembly of the aluminum alloy oil drill pipe. After the draw rope 36 is pulled out, the draw rope 36 can be wound around the limit column, and the insertion rod 37 can be inserted into the card ball of the limit column to fix the draw rope 36, which is convenient for controlling other draw ropes 36 and driving the card block 33 away from the card slot 39 of the second drill pipe 2. By setting the connecting device 3, the installation and disassembly efficiency of the aluminum alloy oil drill pipe is improved, the low connection efficiency of the aluminum alloy oil drill pipe is reduced, and the problem of affecting the work efficiency is reduced, thereby further improving the practicality of the aluminum alloy oil drill pipe.
[0035] The remaining structures are the same as those of Example 1.
[0036] Example 3
[0037] Reference Figure 1 and Figure 3 as well as Figure 5 , which is the third embodiment of the present utility model, and this embodiment is different from the second embodiment in that:
[0038] The surfaces of the first drill rod 1 and the second drill rod 2 are both provided with sealing devices 4, and the sealing devices 4 include two sealing grooves 41, which are respectively opened on the surfaces of the first drill rod 1 and the second drill rod 2, and telescopic rubber sleeves 42 are placed in the sealing grooves 41 on the surfaces of the first drill rod 1 and the second drill rod 2.
[0039] Both ends of the telescopic rubber sleeve 42 are fixedly connected with iron blocks 43, and the sealing grooves 41 on the surfaces of the first drill rod 1 and the second drill rod 2 are fixedly connected with magnetic plates 44.
[0040] During use, before the first drill rod 1 is connected to the second drill rod 2, the telescopic rubber sleeve 42 is placed in the sealing groove 41 of the first drill rod 1. At this time, the iron block 43 contacts and adsorbs the magnetic plate 44 in the first drill rod 1 and is fixed in the first drill rod 1. When the first drill rod 1 is connected to the second drill rod 2, the telescopic rubber sleeve 42 will enter the sealing groove 41 of the second drill rod 2. At this time, the iron block 43 at the other end of the telescopic rubber sleeve 42 will contact and adsorb the magnetic plate 44 in the second drill rod 2. At this time, the iron blocks 43 on both sides of the telescopic rubber sleeve 42 are respectively in contact with the first drill rod 1. It is adsorbed and fixed with the magnetic plate 44 in the second drill rod 2, thereby improving the stability of the telescopic rubber sleeve 42 and facilitating the replacement of the telescopic rubber sleeve 42. When the aluminum alloy oil drill rod is working, the telescopic rubber sleeve 42 can effectively improve the sealing effect of the connection between the first drill rod 1 and the second drill rod 2, and reduce the oil leakage. By setting the sealing device 4, the sealing performance of the aluminum alloy oil drill rod is improved, and the problem of oil leakage after the aluminum alloy oil drill rod is connected is reduced, thereby further improving the use effect of the aluminum alloy oil drill rod.
