Referring to fig. 1-4, an anti-tilt jack comprises a jack main body 1, wherein a mounting ring 2 is mounted at the upper end of the outer annular surface of the jack main body 1, the outer annular surface of the mounting ring 2 is hinged to a first threaded rod 4 through a plurality of rotating frames, a second threaded rod 6 is arranged outside one end, away from the mounting ring 2, of the first threaded rod 4, an adjusting cylinder 5 is meshed between the first threaded rod 4 and the second threaded rod 6 together, the rotating directions of threads between the first threaded rod 4 and the second threaded rod 6 are opposite, a supporting plate 7 is hinged to one end, away from the adjusting cylinder 5, of the second threaded rod 6, and a horizontal measuring ring 8 is arranged on the lower side of the outer annular surface of the mounting ring 2.

As a technical optimization scheme of the utility model, the horizontal measuring ring 8 has light transmission and is hollow inside, colored liquid is filled in the hollow part, and a plurality of scale marks are arranged on the outer annular surface of the horizontal measuring ring 8; the setting of horizontal measurement ring 8 can be so that jack main part 1 when using, and the convenient incline direction to jack main part 1 of personnel judges to be favorable to adjusting jack main part 1, the difficult slope of jack main part 1 when using is placed.

As a technical optimization scheme of the utility model, rectangular grooves are formed in the middle parts of the first threaded rod 4 and the second threaded rod 6, and a rectangular limiting rod 9 matched with the first threaded rod 4 and the second threaded rod 6 is inserted in a sliding manner through the rectangular grooves; the setting of rectangle gag lever post 9 for second threaded rod 6 can't rotate and only can remove, and when personnel were to adjusting section of thick bamboo 5 application of force promptly, its first threaded rod 4 was located the body of rod length of adjusting section of thick bamboo 5 inside with second threaded rod 6 and equals.

As a technical optimization scheme of the utility model, a pressure spring 10 is installed at one end of the rectangular limiting rod 9 extending into the first threaded rod 4, and the other end of the pressure spring 10 is fixedly connected with the bottom of a rectangular groove in the first threaded rod 4; due to the arrangement of the pressure spring 10, when the second threaded rod 6 moves towards one end far away from the first threaded rod 4 under the action of the adjusting cylinder 5, the rectangular limiting rod 9 is ejected outwards by the pressure spring 10, namely, the lower end of the rectangular limiting rod 9 is always located inside a rectangular groove of the second threaded rod 6, and the length of the pressure spring 10 is smaller than that of the rectangular groove, namely, when the rectangular limiting rod 9 is ejected by the pressure spring 10, the upper end of the rectangular limiting rod 9 is also always located inside the rectangular groove of the first threaded rod 4.

As a technical optimization scheme of the utility model, a plurality of accommodating holes are arranged inside the first threaded rod 4 and the second threaded rod 6, and matched reinforcing rods 11 are fixed in the accommodating holes; the hardness of the reinforcing rod 11 is greater than the hardness of the first threaded rod 4 and the second threaded rod 6, that is, the reinforcing rod 11 can improve the structural strength of the first threaded rod 4 and the second threaded rod 6 in use, so that the phenomenon of breakage of the first threaded rod 4 and the second threaded rod 6 in use can be reduced.

As a technical optimization scheme of the utility model, the upper end of the outer ring surface of the adjusting cylinder 5 is rotatably provided with rotating rings 12 through bearings, and elastic ropes 13 are jointly fixed among the rotating rings 12; the setting of swivel 12 and stretch cord 13 can make jack main part 1 after the use, can retrain the regulation section of thick bamboo 5 of each side to make each regulation section of thick bamboo 5 laminating at the outer anchor ring of jack main part 1, thereby make the jack accomodate comparatively conveniently after the use.

As a technical optimization scheme of the utility model, the lower surface of the supporting plate 7 is provided with the anti-skid seat 3, and the lower surface of the anti-skid seat 3 is provided with a plurality of anti-skid nails; the anti-slip seat 3 is arranged, so that the supporting plate 7 is not easy to slide when supporting the jack main body 1.

The use principle and the advantages are as follows: the utility model discloses in the use, when jack main part 1 is using leveling ground, the personnel place jack main part 1 on ground alright, and then jack main part 1 that is vertical state alright lift external heavy object, and because the outer anchor ring of collar 2 is fixed with horizontal measurement ring 8, promptly when jack main part 1 is in vertical state and places, the liquid level of the inside liquid of its horizontal measurement ring 8 is parallel state with horizontal measurement ring 8's inner bottom, and then the liquid level is the same with the numerical value that horizontal measurement ring 8 outer anchor ring corresponded everywhere, and when jack main part 1 is in non-vertical state, the inside liquid of its horizontal measurement ring 8 is to the one side removal of jack main part 1 slope, thereby make liquid level and horizontal measurement ring 8 inner bottom be in non-parallel state, and then the numerical value corresponding with the liquid level between 8 outer anchor ring everywhere is inequality, from this personnel alright through the numerical value that corresponds the liquid level between the scale line everywhere is the same, whether slope to jack main part 1 carries out the accuracy judgement.

Further in this scheme use, after jack main part 1 placed the completion, personnel rotated regulation section of thick bamboo 5, make second threaded rod 6 remove to the one end of keeping away from first threaded rod 4, until the lower surface of backup pad 7 contacts with ground, the application of force to each regulation section of thick bamboo 5 is passed through to the same reason, make each backup pad 7 contact with ground, each backup pad 7 this moment, each first threaded rod 4, regulation section of thick bamboo 5 and second threaded rod 6 constitute a stable triangle-shaped braced frame, thereby support jack main part 1 under this frame's effect, when jack main part 1 unexpected emergence slope, can support jack main part 1 through this frame, thereby can reduce jack main part 1 and lead to the phenomenon of toppling because of the slope, the operational safety when jack main part 1 used has been promoted from this, the defect that traditional jack easily leaned when traditional jack was used on uneven ground has been solved promptly.

Furthermore, in the use process of the scheme, when the jack main body 1 is used outdoors, because the lower surfaces of the supporting plates 7 are in a plate shape, namely, when the jack main body 1 is used through the supporting plates 7, the pressure of the jack main body 1 to the ground is shared, namely, the pressure transmitted to the jack main body 1 by an external heavy object is transmitted to the ground through the lower end surface of the jack main body 1 and the lower surfaces of the supporting plates 7, so that the phenomenon that the jack main body 1 sinks after being stressed when the jack main body 1 is used outdoors can be effectively reduced; simultaneously because the lower surface of its backup pad 7 is equipped with antiskid ribbed tile 3, and the lower surface of antiskid ribbed tile 3 is equipped with a plurality of studs, and then when jack main part 1 used, each stud of its antiskid ribbed tile 3 lower surface can stretch into ground, even make backup pad 7 more firm with the ground contact to make backup pad 7 have better anti-skidding effect.

The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
