And an anti-rotation jackscrew is arranged on the side wall of the mounting sleeve, and the tail end of the anti-rotation jackscrew is abutted to the snap ring. The utility model has the advantages that:
1. the utility model discloses a set up the cable spout, make the assembly of cable convenient and fast more.
2. The utility model discloses a change the connection structure between snap ring and the oil pipe, make the snap ring can not rotate for oil pipe to be in the intraoral cable of opening carries out effectual support, reduces the probability of cable harm.
3. The utility model discloses in, connect through preventing changeing the jackscrew between installation cover and the snap ring to make the installation cover also nonrotatable, thereby further reduced the probability that the cable damaged.
Drawings
Fig. 1 is a schematic structural diagram of the present invention;
FIG. 2 is a cross-sectional view at A in FIG. 1;
fig. 3 is a schematic structural diagram of the snap ring at the view angle of fig. 2.
In the figure: 1-oil pipe, 2-fixing sleeve, 3-mounting sleeve, 4-snap ring, 5-cable, 6-line pressing screw, 7-copper ball, 8-cable chute, 9-bulge, 10-notch and 11-anti-rotation jackscrew.
Detailed Description
The invention is further described below with reference to the accompanying drawings:
as shown in fig. 1, the present embodiment includes an oil pipe 1, a mounting sleeve 3, a fixing sleeve 2, a snap ring 4 and a cable 5, the snap ring 4 is clamped outside the oil pipe 1, the mounting sleeve 3 and the fixing sleeve 2 are connected together by a thread and the snap ring 4 is clamped in the middle, so that the mounting sleeve 3 and the fixing sleeve 2 are mounted on the oil pipe 1, one end of the cable 5 is fixedly connected to the mounting sleeve 3 by a pressing line screw 6 and a copper ball 7, and the other end of the cable 5 is obliquely inserted into a cable passing hole on the pipe wall of the oil pipe 1. The above is a common structure in the prior art, and is not described herein again.
The utility model discloses a most main innovation point is: the side of oil pipe 1 is provided with cable chute 8, and the length direction of cable chute 8 is parallel with the axis of oil pipe 1, and the lower extreme of cable chute 8 links up with the cable hole that crosses on the oil pipe 1. Based on the structure, when the cable is assembled, the lower end of the cable 5 can be inserted into the cable slideway 8 firstly under the condition that the cable 5 is not bent, then the cable 5 and the mounting sleeve 3 slide downwards together until the mounting sleeve 3 abuts against the clamping ring 4, at the moment, the lower end of the cable 5 just reaches the entrance of the cable hole on the oil pipe 1, and at the moment, the cable 5 is not bent, so that the cable can slide in the cable hole very smoothly, and the assembling difficulty is reduced.
