Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in detail:
The utility model provides a kind of Guan Sitou extractor, can be quick, time saving and energy saving be taken out from inside pipe fitting by Guan Sitou, as shown in Figure 1, is the overall structure schematic diagram of the Guan Sitou extractor that the utility model provides; Comprise: sleeve 1, screw mandrel 2, conehead 3 and operating grip 4.Below the architectural feature of each parts is introduced in detail:
As shown in Figure 3, be the structural representation of screw mandrel 2, screw mandrel 2 is three stage structure, comprises the 1st section of screw mandrel 2.1, the 2nd section of screw mandrel 2.2 and the 3rd section of screw mandrel 2.3; Wherein, the 2nd section of screw mandrel 2.2 is positioned at the inside of sleeve 1, and is connected with the inner thread of sleeve 1; The 3rd section of screw mandrel 2.3 is extended back from the tail end of the 2nd section of screw mandrel 2.2, the afterbody of the 3rd section of screw mandrel 2.3 is made to be positioned at the outside of sleeve 1 tail end, at the afterbody fixed installation operating grip 4 of the 3rd section of screw mandrel 2.3, for easy for installation, operating grip can adopt the locking nut with the external screw thread adaptation of the 3rd section of screw mandrel 2.3.
Extend forward the 1st section of screw mandrel 2.1 from the front end of the 2nd section of screw mandrel 2.2, and the front end of the 1st section of screw mandrel 2.1 extends to the outside of sleeve 1 front end, the tail end of the 1st section of screw mandrel 2.1 is positioned at the inside of sleeve 1; The external diameter of the 1st section of screw mandrel 2.1 is less than the internal diameter of sleeve 1, thus there is gap between the tail end and the inwall of sleeve 1 of the 1st section of screw mandrel 2.1;
As shown in Figures 2 and 3, be the conehead structural representation of two kinds of different sizes, the cone tip portion of conehead 3 is offered and the 1st section of installing hole that screw mandrel 2.1 is suitable, and installing hole is sheathed on the outside of the 1st section of screw mandrel 2.1, and is fixedly connected with the 1st section of screw mandrel 2.1; In addition, the cone tip portion of conehead 3 is positioned at the inside of sleeve 1 front end; The cone seat part of conehead 3 is positioned at the outside of sleeve 1 front end; Unique difference of Fig. 2 and Fig. 3 is: the diameter of section of cone seat is not identical, can according to the actual requirements, the conehead that design section diameter is different, as shown in Figure 2, for cone seat diameter of section is the cone point of 12 centimetres; As shown in Figure 3, for boring the cone point that seat diameter of section is 10 centimetres; In Fig. 2 and Fig. 3, the diameter of installing hole is identical, because the installing hole of the cone tip portion of conehead 3 and the 1st section of screw mandrel 2.1 removably connect, therefore, can according to the actual requirements, the conehead of apolegamy different size.
As shown in Figure 5, be the structural representation of sleeve, the front end edge of sleeve 1 axially offers at least one groove 1.1, and the front end of sleeve is had can the function of tensioner; The outer wall of sleeve 1 front end is provided with external screw thread 1.2, for mating with needing the internal thread of the Guan Sitou taken out; Also comprise detachable nut 5; Detachable nut 5 is detachably sheathed on the outer wall of sleeve 1, acting as of detachable nut: facilitate turnbarrel.
The Guan Sitou extractor that the utility model provides, its operation principle is:
(1) according to fractureing the pipe silk area of bed size in pipe fitting, the conehead of corresponding specification is selected;
(2) installing hole of conehead is threaded connection the sheathed outside being fixed on the 1st section of screw mandrel of mode, is threaded connection mode at the tail end of the 3rd section of screw mandrel and operating grip is installed;
Now, because conehead screws in the limited length of sleeve lining, therefore, there is gap between sleeve top and conehead, sleeve is in non-tensioner state;
(3) with reference to figure 1, to insert in the internal orifice of the Guan Sitou fractureed in above-mentioned Guan Sitou extractor away from one end of operating grip, because sleeve lining and screw mandrel are thread connecting mode, therefore, ensure that sleeve does not rotate, rotating operating handle, operating grip is rotated, thus moving right that screw mandrel is rotated around sleeve lining, and then drive conehead to move right, because the diameter of section of conehead increases gradually from right each left side, therefore, when in the process that conehead moves right, the conehead diameter of section entering sleeve inner is increasing, thus expanded in the front end of sleeve, after the front end swelling of sleeve, the internal thread of the external screw thread and Guan Sitou that can reach sleeve outer wall is meshed, use instrument reversely rotates detachable nut 5, because detachable nut is fixedly connected with sleeve outer wall, thus drive sleeve rotating, again because the external screw thread of sleeve outer wall is meshed with the internal thread of Guan Sitou, therefore, in the process that sleeve rotating is moved to the left, the external screw thread of sleeve outer wall takes the outside of pipe fitting to the right out of by Guan Sitou, reach the object of take-off pipe silk head.
The Guan Sitou extractor that the utility model provides has the following advantages:
Guan Sitou extractor can be quick, time saving and energy saving Guan Sitou is taken out from inside pipe fitting, and, in the process of take-off pipe silk head, the internal thread of pipe fitting can not be damaged, thus improve overhaul efficiency.Also have structure simple, design ingenious and that cost is low advantage, can promote the use of on a large scale.
The above is only preferred embodiment of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should look protection domain of the present utility model.
