Abstract
The utility model relates to an inclined plane base plate for a jack and belongs to the technical field of jack accessories. Due to the fact that a working surface is required to be a plane according to the jack and many outdoor environments are inclined plane environments, great obstacles are caused to use of the jack, and the inclined plane base plate is designed so that the jack can be suitable for the inclined plane conditions. The inclined plane base plate is simple in structure, high in bearing capacity, convenient to carry and suitable for use of the jack under the conditions of special outdoor environments.
Description
Technical field
Machine tool field, particularly a kind of jack canted tie plate under the utility model.
Technical background
Known, jack is requisite in daily machine tool, but general jack, no matter be that mechanical jack, hydraulic jack or scissor-like jack are all difficult to well work stable on inclined-plane.This defect is that the use of jack causes great obstruction.Thereby jack canted tie plate arises at the historic moment, however existing jack canted tie plate insufficient strength, will be by conquassation when being subject to large load.
Summary of the invention
For the existing problem of existing ordinary jack, solution is proposed, a kind of jack canted tie plate, can adjust easily angle and adapt to different inclined-planes, and can carry larger load, simultaneously simple in structure, the low cost of manufacture of this canted tie plate, bearing capacity are large, can increase work efficiency and the Applicable scope of jack.
This jack pad is by Upper gasket, lower gasket, and the hinged strut bar composition forming of several truss, wherein has a body frame, and the purposes of body frame is to adjust the angle of angle, adapts to different inclined-planes.When body frame bar upwards lifts, drive the bracing frame hinged with it to lift, bracing frame is comprised of several high strength strut bars, the length of its each bar, be directly proportional to its distance to upper and lower two pads, meet similar triangle theory, so the force direction that is subject to of each strut bar is identical, therefore it is stressed evenly, can carry larger load.
the beneficial effects of the utility model are: the utility model, simple in structure, cheap, can bear large load.
Accompanying drawing explanation
below in conjunction with drawings and Examples, the utility model is described in further detail.
Fig. 1 is the schematic diagram of the integral structure sketch of embodiment of the present utility model.
Fig. 2 is the triangle relation schematic diagram of each pole length of the present utility model.
In Fig. 1 and Fig. 2: 1-lower gasket; 2-Upper gasket; Friction groove on 3-Upper gasket; The latch that upper and lower two pads of 4-connect; 5-pin hole; 6-adjusting lever; 7-load lever; The hinge of 8-load lever and lower gasket.
The specific embodiment
As Fig. 1, lower gasket is positioned on inclined-plane, adjusting lever is upwards lifted, the angle in adjustment between lower gasket, in the process that adjusting lever lifts, strut bar also lifts, and several they sup-port play Upper gasket.Because strut bar and adjusting lever form triangle, and strut bar has and increases the groove rubbing with Upper gasket contact position, so strut bar stability fine being difficult for skids, can carry large load.
As Fig. 2, Fig. 2 illustrated, each strut bar and between length relation, triangle oaA, obB, ocC, odD are similar triangle, so be easy to get, can obtain following relation as figure:
Claims (4)
1. a jack canted tie plate, by upper lower bolster, adjusting lever, strut bar, latch forms, and it is characterized in that: upper lower gasket, adjusting lever connect at same axis upper hinge, each strut bar is connected through the hinge with lower gasket again, each strut bar again with adjusting lever chain connection.
2. jack canted tie plate according to claim 1, is characterized in that: adjusting lever and each strut bar chain connection, can adjust angle and fixed pedestal bar position between backing plate.
3. jack canted tie plate according to claim 1, is characterized in that: the length of strut bar meets similar triangle theorem, and each bar grows up to proportionate relationship.
4. jack canted tie plate according to claim 1, is characterized in that: can bearing load thereby can require the number of increase strut bar to strengthen according to load.
