Specific embodiment
In order to make the object, technical scheme and advantages of the embodiment of the invention clearer, below in conjunction with the embodiment of the present invention
In attached drawing, technical scheme in the embodiment of the invention is clearly and completely described, it is clear that described embodiment is
A part of the embodiment of the present invention, instead of all the embodiments.The present invention being usually described and illustrated herein in the accompanying drawings is implemented
The component of example can be arranged and be designed with a variety of different configurations.
Fig. 1, Fig. 2, Fig. 3 and Fig. 4 are please referred to, it mainly to include center-pole that the present embodiment provides a kind of oil well fishing devices
1, the connector being fixedly connected with 1 top of center-pole and the blocking portion 3 being fixedly connected with 1 bottom end of center-pole.Wherein connector
Top and the equipment of outside be attached, the bottom of connector is to be screwed to connect with the connection type of center-pole 1, blocking
Portion 3 and center-pole 1 are integrated formed structures, and the bottom of blocking portion 3 herein is structure tapered from top to bottom, to reduce oil well
The active area of middle liquid improves the efficiency moved downward.
1 side wall of center-pole is equipped with multiple salvaging parts 4, and multiple salvaging parts 4 uniformly divide in the circumferential direction of center-pole 1
Cloth, salvaging part 4 includes arc panel 41 and crook 43, and crook 43 is fixedly connected with the bottom of arc panel 41, and crook 43
Extend along the direction far from center-pole 1.It is in angle between elongated end and arc panel 41 of the crook 43 far from 1 direction of center-pole
Setting, and this angle is acute angle, it, herein can be according to the specific article tune salvaged in order to catch on corresponding article inside oil well
The lesser salvaging part 4 of angle can be selected when article is the article of rope class in whole angle；It is selected when article is instrument or part
With the biggish salvaging part 4 of angle.Furthermore it should be noted that herein multiple are not limited to shown in Fig. 3 three, also can be
Two, four or more, quantity and size as the case may be depending on.
Preferably, the upper surface of crook 43 is rough surface, rough surface herein be can be with groove or bulge-structure
End face, to increase the frictional force between crook 43 and article.
Wherein, it salvages part 4 and is connect with the side wall of center-pole 1 by fixing bolt 6, wherein arc panel 41 and center-pole 1 are logical
The connection of fixing bolt 6 is crossed, salvaging has spacing between part 4 and the side wall of center-pole 1, and fixing bolt 6 is located at salvaging part 4 in
The first elastomeric element 7 is arranged on screw rod between 1 side wall of core bar, center-pole 1 is located at the bar salvaged between part 4 and blocking portion 3
Portion is arranged with the holding firmware 5 cooperated with salvaging part 4, and holding firmware 5 is slided along 1 length direction of center-pole, and holding firmware 5 is equipped with and is used for
Salvage the card slot that 4 end of part is protruded into.It salvages part 4 and to protect between salvaging part 4 and center-pole 1 by the spring on fixing bolt 6
Hold at regular intervals, when device provided in this embodiment is not put into inside oil well, the end for salvaging part 4 is protruded into inside card slot,
The position that card slot can limit salvaging part 4 can pass through certain instruments to reduce the diameter of whole device in sinking watching
Cross the hole portion of component；When device rises, since liquid has biggish resistance, work of the holding firmware 5 in this resistance to holding firmware 5
The top of blocking portion 3 is moved under, at the same time, salvage part 4 get rid of limitation, and under the action of the first elastomeric element 7 to
On the one hand movement outside increases salvaging amount, on the other hand can salvage with hole portion to effectively increase radius and the region of salvaging
Instrument and component, thus be suitable for underground difference article salvaging.
For above-described embodiment, card slot can be the shapes and sizes to match with crook 43.Preferably one, card slot
Shape is circular ring shape.For convenience of the replacement for salvaging part 4, the quantity and size for salvaging part 4 are had differences, therefore circular card slot
It can satisfy different number and different size of crook 43.
Further, the bottom of crook 43 is equipped with tooth socket 53, and holding firmware 5 is equipped with the teeth portion 51 cooperated with tooth socket 53,
For device during decline, liquid can generate upward resistance to holding firmware 5, and holding firmware 5 can act on the crook for salvaging part 4
43, and holding firmware 5 and the contact area of crook 43 are limited, if the too fast card slot that will lead to holding firmware 5 of the decrease speed of device
Locate stress to increase, the damage of holding firmware 5 and crook 43 is caused to occur cracking or damage, on the one hand may be used by the way that teeth portion 51 is arranged
The contact area for increasing holding firmware 5 and crook 43, reduces pressure between the two, on the other hand, also can prevent holding firmware 5 from existing
It shifts during decline and crook 43 is caused to be detached from card slot, the problem of moving outward in advance.
Further, center-pole 1 is located at the bar portion side wall salvaged between part 4 and blocking portion 3 and (schemes not equipped with a plurality of sliding rail
Show), sliding rail is arranged along the length direction of center-pole 1, and a plurality of sliding rail is uniformly distributed along the circumferential direction of center-pole 1, holding firmware 5
Inner wall be equipped with sliding slot corresponding with sliding rail.It can prevent holding firmware 5 from revolving relative to center-pole 1 by setting sliding rail and sliding slot
Turn, to guarantee that the tooth socket 53 of crook 43 is matched with the teeth portion 51 on holding firmware 5.
The second elastomeric element 8 is additionally provided between part 4 and center-pole 1 preferably, salvaging, and the second elastomeric element 8 is located at admittedly
The lower section for determining bolt 6, in device uphill process, holding firmware 5 is moved at blocking portion 3, and salvages part 4 in the second elastic portion
A part of liquid resistance can be overcome to make to keep certain angle between salvaging part 4 and center-pole 1 under the action of part 8, to guarantee
The salvaging area and salvaging amount of device.It should be noted that above-mentioned the first elastomeric element 7 and the second elastomeric element 8 is hard
Matter spring, in addition, the length of the second elastomeric element 8 is greater than the length of the first elastomeric element 7, and the elasticity of the second elastomeric element 8
Coefficient is greater than the coefficient of elasticity of the first elastomeric element 7.
The above, only presently preferred embodiments of the present invention, are not intended to limit the invention, patent protection model of the invention
It encloses and is subject to claims, it is all to change with equivalent structure made by specification and accompanying drawing content of the invention, similarly
It should be included within the scope of the present invention.
