Abstract

The utility model is related to a kind of high alloy wear-resistance hollow thread connecting tubes, including light shell of column and thread segment, light shell of column and thread segment are coaxial, the appearance of thread segment is provided with external screw thread, and endoporus is provided at connecting tube axis, and endoporus is divided into two sections, respectively diameter holes and large diameter hole, it is the oblique shoulder of taper between diameter holes and large diameter hole, large diameter hole is wherein all inside thread segment, oblique shoulder is in light shell of column.The first connector and the second connector are penetrated inside connecting tube, nut is screwed in outside thread segment to be fixed, the oblique shoulder of taper positions connector between diameter holes and large diameter hole, and it may insure the axis direction of connector by oblique shoulder, the axis of connector and the axis of connecting tube is avoided misaligned clamping stagnation occur, positioning is influenced, threaded tube, which postpones, avoids connector from being directly exposed to outside, so as to improve the corrosion-resistant and anti abrasive performance of connector.

Description

High alloy wear-resistance hollow thread connecting tube
Technical field
The utility model is related to a kind of connecting tube, especially a kind of high alloy wear-resistance hollow thread connecting tube.
Background technology
In each engineering, it has been typically necessary connector and has been attached, but due to the environmental factor of engineering so that connection Environment residing for part is equally relatively more severe, this just brings the requirement in some uses to connector, such as in outdoor application, Requirement to the corrosion-resistant of connector and abrasion.These requirements are allowed for existing connector and can quickly be shortened using the rear service life, The frequency that connector is replaced increases.
Then, technical staff, which can use corrosion-resistant material or can improve lost material, is used as connector, but Be this connector cost it is higher, and put and use during inevitably cause connector surface damage so that connection The corrosion resistance of part declines, and the position can become the bursting point of security risk.
Invention content
The purpose of this utility model is to provide a kind of high alloy wear-resistance hollow thread connecting tube, is placed on outside connector, For protecting connector so that connector is outer without being directly exposed to, and improves the corrosion-resistant and anti abrasive performance of connector.
The specific technical solution of the utility model is:A kind of high alloy wear-resistance hollow thread connecting tube, including light shell of column and Thread segment, light shell of column and thread segment are coaxial, and the appearance of thread segment is provided with external screw thread, and endoporus is provided at connecting tube axis, interior Hole is divided into two sections, respectively diameter holes and large diameter hole, is the oblique shoulder of taper between diameter holes and large diameter hole, wherein inside thread segment Large diameter hole is all, oblique shoulder is in light shell of column.The first connector and the second connector are penetrated inside connecting tube, is revolved outside thread segment Enter nut to be fixed, the oblique shoulder of taper positions connector between diameter holes and large diameter hole, and can be true by oblique shoulder Protect connector axis direction, avoid connector axis and connecting tube axis it is misaligned there is clamping stagnation, influence to position, screw thread Pipe sleeve, which postpones, avoids connector from being directly exposed to outside, so as to improve the corrosion-resistant and anti abrasive performance of connector.
Preferably, the external screw thread of the thread segment is left hand thread.
Preferably, the external screw thread of thread segment is stepped tooth, the tooth socket angle of stepped tooth is 55 °.
Preferably, the outer diameter of light shell of column is equal with the outer diameter of thread segment, thread segment is outside the last lap of light shell of column The depth of the tooth socket of screw thread is less than the depth of other tooth sockets.
Preferably, the outer surface nitriding of connecting tube, nitriding layer 0.01-0.015mm, the case hardness of connecting tube reach HV550。
The beneficial effects of the utility model are:The first connector and the second connector are penetrated inside connecting tube, outside thread segment Portion screws in nut and is fixed, and the oblique shoulder of taper positions connector between diameter holes and large diameter hole, and can by oblique shoulder To ensure the axis direction of connector, avoid connector axis and connecting tube axis it is misaligned there is clamping stagnation, influence to position, Threaded tube, which postpones, avoids connector from being directly exposed to outside, so as to improve the corrosion-resistant and anti abrasive performance of connector.

Specific embodiment
Below by specific embodiment, and with reference to attached drawing, the utility model will be further described.
Embodiment 1:A kind of high alloy wear-resistance hollow thread connecting tube(Referring to Fig. 1), it is made of 42CrMo, including light beam Section 1 and thread segment 2, light shell of column and thread segment are coaxial, and the appearance of thread segment is provided with external screw thread, are provided at connecting tube axis interior Hole, endoporus are divided into two sections, respectively diameter holes 5 and large diameter hole 3, are the oblique shoulder 4 of taper, wherein spiral shell between diameter holes and large diameter hole Line intersegmental part is all large diameter hole, and oblique shoulder is in light shell of column., the outer diameter of light shell of column is equal with the outer diameter of thread segment, and thread segment leans on The depth of the externally threaded tooth socket of last lap of dipped beam shell of column is less than the depth of other tooth sockets.The outer surface nitriding of connecting tube, oozes Nitrogen layer 0.01mm, the case hardness of connecting tube reach HV550.
The external screw thread of thread segment is left hand thread, and the external screw thread of thread segment is stepped tooth, and the tooth socket angle 6 of stepped tooth is 55°(Referring to Fig. 2).
The above is only the preferred embodiment of the utility model, not the utility model imposed any restrictions, every According to any simple modification, change and equivalent transformation that the utility model technical spirit makees above example, still fall within The protection domain of technical solutions of the utility model.
