Abstract
The invention discloses a portable tool for disassembling a bearing. The portable tool comprises a connecting part, a screw rod and two knuckles, wherein a threaded connection cylinder is arranged at the middle part of the connecting part; the screw rod is in mutual threaded connection with the threaded connection cylinder; an inverted T-shaped regulation guide rail is arranged at the bottom of the connecting part; and an inverted T-shaped connection groove is formed in the upper end of each knuckle and is connected with the inverted T-shaped regulation guide rail in a sliding manner. The portable tool for disassembling the bearing has the advantages that with the inverted T-shaped regulation guide rail and the inverted T-shaped connection grooves, regulation is convenient and rapid, and the portable tool can be suitable for bearings in more diameter specifications; and in addition, with arrangement of a rolling ball at the lower end of the screw rod, the operation is saving in labor.
Description
Technical field
The present invention relates to a kind of portable dam, more precisely a kind of portable dam for dismantling bearing.
Background technology
Pressure between bearing and the axle of interference fit is very big, frictional force is also bigger, due to phenomenon of getting rusty between axle and bearing after long-time use, also result in the connection between bearing and axle very tight, it is difficult to take apart, in order to remove and change the bearing of damage, the instrument of dismounting bearing of the prior art, when dismantling bearing, very easily damages axle, and operation is wasted time and energy, heavier-weight, not readily portable.
Summary of the invention
The present invention mainly solves the technical problem existing for prior art, thus providing a kind of with inverse-T-shaped adjustment guide rail and inverse-T-shaped link slot, easy to adjust quickly, the bearing of more diameter specifications can be applicable to, and the lower end of screw rod is provided with ball, the portable dam for dismantling bearing of rapid operation.
The above-mentioned technical problem of the present invention is addressed mainly by following technical proposals:
A kind of portable dam for dismantling bearing, including a junction, a screw rod and two hooks, the middle part of described connecting portion is provided with a threaded cylinder, described screw rod is mutually threaded with described cylinder of threadeding, the bottom of described connecting portion is provided with an inverse-T-shaped adjustment guide rail, the upper end of described hook is provided with an inverse-T-shaped link slot, and described inverse-T-shaped link slot is connected with described inverse-T-shaped adjustment slide.
As preferred embodiment of the present invention, the lower end of described screw rod is provided with a ball.
As preferred embodiment of the present invention, described hook also includes a fastening bolt, and described fastening bolt extends vertically through to be arranged in described hook.
The advantage for the portable dam of dismantling bearing of the present invention is: with inverse-T-shaped adjustment guide rail and inverse-T-shaped link slot, easy to adjust quickly, it is possible to suitable in the bearing of more diameter specifications, and the lower end of screw rod is provided with ball, rapid operation.

Detailed description of the invention
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described in detail, so that advantages and features of the invention can be easier to be readily appreciated by one skilled in the art, thus protection scope of the present invention being made apparent clear and definite defining.
The advantage for the portable dam of dismantling bearing of the present invention is: with inverse-T-shaped adjustment guide rail and inverse-T-shaped link slot, easy to adjust quickly, it is possible to suitable in the bearing of more diameter specifications, and the lower end of screw rod is provided with ball, rapid operation.
As shown in Figure 1 and Figure 2, a kind of portable dam for dismantling bearing, including a junction 1, screw rod 2 and two hooks 3,
As it is shown on figure 3, the middle part of this connecting portion 1 is provided with a threaded cylinder 11, it is mutually threaded that this screw rod 2 threadeds cylinder 11 with this,
As shown in Figure 3, the bottom of this connecting portion 1 is provided with an inverse-T-shaped adjustment guide rail 12, and as shown in Figure 4, the upper end of this hook 3 is provided with an inverse-T-shaped link slot 31, as shown in Figure 1 and Figure 2, this inverse-T-shaped link slot 31 is slidably connected with this inverse-T-shaped adjustment guide rail 12.
As shown in Figure 1 and Figure 2, the lower end of this screw rod 2 is provided with a ball 21.
As shown in Figure 1, Figure 2, Figure 4 shows, this hook 3 also includes a fastening bolt 32, and this fastening bolt 32 extends vertically through to be arranged in this hook 3.The width of this inverse-T-shaped link slot 31 can be regulated such that it is able to make this inverse-T-shaped link slot 31 and this inverse-T-shaped adjustment guide rail fix and be connected by this fastening bolt 32, safe and reliable.
The mentality of designing of the present invention is below only described in one embodiment, and when system allows, the present invention can expand to external more functional module simultaneously, thus extending its function to greatest extent.
The above, be only the specific embodiment of the present invention, but protection scope of the present invention be not limited thereto, any change expected without creative work or replacement, all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with claims protection defined.
