Abstract

The invention discloses an electromagnetic pipe which comprises an armature, a push rod, a locating block, a pole shoe and a conduit. The push rod is sleeved in the pole shoe, two ends of the push rod respectively extend out of two opposite end faces of the pole shoe, the pole shoe is sleeved outside one end of the push rod and abuts against one end face of the armature, and the locating block is sleeved outside the other end of the push rod and abuts against the other end face of the armature. The conduit is sleeved outside the armature, two ends of the conduit respectively extend out of the armature and the locating block to be at least respectively covered at the other end of the armature and one end of the locating block, clamping grooves along the circumference of the armature and the circumference of the locating block are respectively arranged at the other end of the armature and the outer circumference of on end of the locating block, the positions of two ends of the conduit opposite to the clamping grooves are respectively buckled in the clamping grooves, and protruded parts are correspondingly formed at the positions of two ends of the conduit opposite to the clamping grooves. The electromagnetic pipe is simple in structure and convenient to assemble, production cost of enterprises can be greatly reduced simultaneously, and the enterprises can have great profit margins.

Description

Solenoid tube

Technical field

The present invention relates to a kind of solenoid tube.

Background technology

Present solenoid tube generally adopts brazing to be connected on conduit and the pole shoe, utilizes the non-magnetic effect of copper, magnetic field is intercepted come, and makes to form magnetic field in the bit copper district, with the field of load of better control magnetic line of force displacement curve.This solenoid tube is owing to the employing brazing connects, so the processing cost of this structure is higher, thereby has reduced the profit space of enterprise.

Summary of the invention

In order to overcome above-mentioned defective, the invention provides a kind of solenoid tube, can reduce enterprise's production cost significantly, for enterprise gets bigger profit margin.

The present invention for the technical scheme that solves its technical problem and adopt is: a kind of solenoid tube, comprise armature, push rod, locating piece, pole shoe and conduit, described pushing rod sleeve is located in the described pole shoe and stretch out respectively outside the relative both ends of the surface of this pole shoe at two ends, it is outer and near an end face of described armature that described pole shoe is sheathed on an end of described push rod, and it is outer and near another end face of described armature that described locating piece is sheathed on the other end of described push rod; Described sheathed catheter is located at described armature outer and two ends extend to described armature respectively and locating piece coats the other end of described armature and an end of locating piece in it at least respectively outward, be respectively equipped with along its circumferential draw-in groove at the other end of described armature and an end outer peripheral face of locating piece, the two ends of described conduit are withheld respectively in this draw-in groove and the corresponding protuberance that forms over against this draw-in groove position.

As a further improvement on the present invention, described conduit is that non-magnet_conductible material is made.

As a further improvement on the present invention, described conduit is made for the stainless steel material.

As a further improvement on the present invention, in the draw-in groove of described pole shoe and locating piece, be respectively equipped with sealing ring.

The invention has the beneficial effects as follows: this solenoid tube structure does not need welding, and easy to assembly, cost adopts stainless conduit, and cost reduces greatly, promotes the profit margin of enterprise, can guarantee the field of load of the magnetic force displacement curve of product simultaneously yet.

Description of drawings

Fig. 1 is cross-sectional view of the present invention;

By reference to the accompanying drawings, make the following instructions:

1---armature 2---push rod

3---locating piece 4---pole shoe

5---conduit 6---draw-in groove

7---protuberance 8---sealing ring

Embodiment

By reference to the accompanying drawings, the present invention is elaborated, but protection scope of the present invention is not limited to following embodiment, namely the simple equivalent of being done with the present patent application claim and description in every case changes and modifies, and all still belongs within the patent covering scope of the present invention.

As shown in Figure 1, a kind of solenoid tube, comprise armature 1, push rod 2, locating piece 3, pole shoe 4 and conduit 5, described pushing rod sleeve is located in the described pole shoe and stretch out respectively outside the relative both ends of the surface of this pole shoe at two ends, it is outer and near an end face of described armature that described pole shoe is sheathed on an end of described push rod, and it is outer and near another end face of described armature that described locating piece is sheathed on the other end of described push rod; Described sheathed catheter is located at described armature outer and two ends extend to described armature respectively and locating piece coats the other end of described armature and an end of locating piece in it at least respectively outward, be respectively equipped with along its circumferential draw-in groove 6 at the other end of described armature and an end outer peripheral face of locating piece, the two ends of described conduit are withheld respectively in this draw-in groove and the corresponding protuberance 7 that forms over against this draw-in groove position.During assembling, earlier pole shoe is inserted in conduit one end, then armature is inserted in it from the conduit other end, and then the assembling of push rod and locating piece is inserted in the conduit together and together, with the mode of withholding the two ends of conduit are fixed with pole shoe and locating piece respectively at last, because the draw-in groove position of the corresponding pole shoe of extruded conduit medial surface and locating piece forms protuberance respectively, thereby realizes fixedlying connected of conduit and pole shoe and locating piece.This solenoid tube is simple for structure, and is easy to assembly, satisfying under the situation of excellent product performance, can effectively save cost, promotes the enterprise profit space.

Preferably, described conduit is that non-magnet_conductible material is made.

Preferably, described conduit is made for the stainless steel material.

Preferably, in the draw-in groove of described pole shoe and locating piece, be respectively equipped with sealing ring 8.
