Abstract
The invention discloses a transverse-stress-induction jack which comprises a body. A plurality of fixing pieces are disposed on the lateral side of the bottom of the body. A first fixing point and a second fixing point are disposed at the bottom of the body. An elongation stress induction vertex is disposed on the lateral side of the body. The body is made of high-strength hard steel. The first fixing point and the second fixing point are made of telescopic high-strength hard steel. Due to the elongation stress induction vertex of the transverse-stress-induction jack is provided with a stress inductor, automatic and slow force relieving is achieved when the stress exceeds rated force, a stressed device is protected effectively, and destroying caused by excessively-large stress is avoided. Due to the fact that the body is made of high-strength hard steel, element safety operation is guaranteed, and safety coefficient is increased.
Description
Technical field
The present invention relates to a kind of jack, or rather, is a kind of lateral stressed induction jack.
Background technology
Jack is the highly little the simplest weight-lifting equipment of a kind of lifting, lifts part as equipment, the light little weight-lifting equipment of jacking weight in stroke by top bracket or bottom claw with rigidity top.Existing jack does not have stress sensor mostly, thus the material low to some intensity easily causes damage.
Summary of the invention
The present invention mainly solves the technical matters existing for prior art, thus provides a kind of lateral stressed induction jack of available protecting device.
Above-mentioned technical matters of the present invention is mainly solved by following technical proposals:
A kind of lateral stressed induction jack, comprises a body, establishes some fixed plates in described body bottom portion side, establish one first attachment point and one second attachment point at described body bottom portion, establish a stressed induction summit of elongation in described body side.
As preferred embodiment of the present invention, described body is that high strength hard steel is made.
As preferred embodiment of the present invention, the first described attachment point and the second attachment point are that scalable high strength hard steel is made.
Because the stressed induction summit of elongation described in lateral stressed induction jack of the present invention is provided with stress sensor, when stressed exceed nominal force time, this element slowly unloads power voluntarily, thus actv. protects stressed device, avoids excessively damaging because of stressed.Because described body is that high strength hard steel is made, thus ensure that the safe operation of element, improve safety factor.
Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the perspective view of lateral stressed induction jack of the present invention;
Fig. 2 is the perspective view of the lateral stressed induction jack in Fig. 1, is now another visual angle.
Detailed description of the invention
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described in detail, can be easier to make advantages and features of the invention be readily appreciated by one skilled in the art, thus more explicit defining is made to protection scope of the present invention.
The invention provides a kind of lateral stressed induction jack of available protecting device.
As shown in Figure 1 and Figure 2, a kind of lateral stressed induction jack 1, comprises a body 2, establishes some fixed plates 3 in described body 2 bottom sides, bottom described body 2, establish one first attachment point 41 and one second attachment point 42, establish a stressed induction summit 5 of elongation in described body 2 side.
As shown in Figure 1 and Figure 2, described body 2 is made for high strength hard steel.
As shown in Figure 1 and Figure 2, the first described attachment point 41 and the second attachment point 42 are made for scalable high strength hard steel.
The stressed induction summit of elongation described in lateral stressed induction jack of this invention is provided with stress sensor, when stressed exceed nominal force time, this element slowly unloads power voluntarily, thus actv. protects stressed device, avoids excessively damaging because of stressed.Because described body is that high strength hard steel is made, thus ensure that the safe operation of element, improve safety factor.
Below only in one embodiment mentality of designing of the present invention is described, when system allows, the present invention can expand to external more functional module simultaneously, thus expands its function to greatest extent.
The above, be only the specific embodiment of the present invention, but protection scope of the present invention is not limited thereto, and any change of expecting without creative work or replacement, all should be encompassed within protection scope of the present invention.Therefore, the protection domain that protection scope of the present invention should limit with claims is as the criterion.
Claims (3)
1. a lateral stressed induction jack (1), comprise a body (2), it is characterized in that, some fixed plates (3) are established in described body (2) bottom sides, establish one first attachment point (41) and one second attachment point (42) in described body (2) bottom, establish the stressed induction summit (5) of an elongation in described body (2) side.
2. lateral stressed induction jack according to claim 1, is characterized in that, described body (2) is made for high strength hard steel.
3. lateral stressed induction jack according to claim 2, is characterized in that, described the first attachment point (41) and the second attachment point (42) are made for scalable high strength hard steel.
