Abstract
The utility model discloses an adjustable iron pad which comprises a support cylinder and an adjusting rod. The support cylinder comprises a cylinder body and a support plate which is arranged at the upper portion of the cylinder body, wherein the support plate is provided with a through hole which has a long diameter and a short diameter. The adjusting rod is axially provided with a plurality of projections, the spacing between neighboring projections is larger than the thickness of the support plate, every projection has a long side and a short side, the length of the long side of the projections is shorter than that of the long diameter of the through hole and longer than that of the short diameter of the through hole, and the length of the short side of the projection is shorter than that of the short diameter of the through hole. The adjusting rod penetrates through the through hole and is arranged inside the support cylinder. The height of the adjustable iron pad can be adjusted by adjusting the extended length of the adjusting rod inside the support cylinder, all the components cannot be damaged in long-term use, so that the adjustable iron pad has the advantages of being simple in structure, long in service life and easy to use and operate.
Description
Technical field
The utility model belongs to machinery support technology field, is specifically related to a kind of adjustable iron gasket.
Background technique
Traditional parallels is the cylinder of certain size, when liner, after suitably being raised, equipment stacks the parallels of needed height, and the adjusting of liner height is to realize by the number that stacks that reduces or increase parallels, this mode not only wastes time and energy but also supports unstablely, has potential safety hazard.
For this reason, the adjustable iron gasket that different structure correspondingly occurred, adjustable sizing block as disclosed in ZL201010195783 is to regulate the height of parallels by unscrewing or screw screw and nut with special supporting spanner, this adjustable sizing block in use for some time, the damage of screw or nut may occur, need to change corresponding component, and then affect the working life of parallels, and when regulating highly the unscrewing and screw and need to expend too much manpower of nut.
Summary of the invention
For defective or the deficiency that prior art exists, technical problem to be solved in the utility model is to provide a kind of simple in structure, long service life and uses adjustable iron gasket simple to operate.
For this reason, the adjustable iron gasket that provides of the utility model comprises supporting drum and adjustable lever; Described supporting drum comprises cylindrical shell and the dunnage that is located at cylindrical shell top, offers through hole on described dunnage, and this through hole is provided with major diameter and minor axis; Be provided with vertically some projections on described adjustable lever, and adjacent projections spacing in the axial direction is greater than the thickness of dunnage, each projection is equipped with long limit and minor face; The size on the long limit of each projection is less than the size of the major diameter of described through hole and greater than the size of the minor axis of described through hole, the size of the minor face of each projection is less than the size of the minor axis of described through hole; Described adjustable lever via through holes is assemblied in supporting drum.
Other technologies of the present utility model are characterized as:
Described through hole is rectangular through holes, and the horizontal section of described each projection is rectangular.
Described adjustable lever is hollow stem.
Offer corresponding erection opening on described supporting drum and adjustable lever.
Adjustable sizing block of the present utility model is regulated the height of parallels by regulating the degree of stretching into of adjustable lever in supporting drum, the situation that each parts can not occur damaging when long-term the use has simple in structure, long working life and use characteristics simple to operate.In addition, adjustable lever adopts hollow structure to reach and saves material and the purpose that reduces parallels weight; And establish erection opening by corresponding position on supporting drum and adjustable lever and can reach the convenient purpose that moves and install.
Description of drawings
Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail.
Fig. 1 is the structural representation of adjustable sizing block of the present utility model;
Fig. 2 is the structural representation of supporting drum;
Fig. 3 is the plan view of Fig. 2;
Fig. 4 is the A-A sectional view of Fig. 2.
Embodiment
Embodiment 1:
referring to figs. 1 to Fig. 4, this embodiment's adjustable iron gasket comprises supporting drum 1 and T-shaped adjustable lever 2, described supporting drum 1 comprises base 5 and the dunnage 6 that is located at the cylindrical tube 4 on base 5 and is located at cylindrical shell 4 upper end portions, offer on described dunnage 6 with cylindrical shell 4 in the rectangular through holes 7 that communicates, it is rectangular projection 3 that described adjustable lever 2 is provided with a plurality of level cross-sectionns, and adjacent projections 3 spacing in the axial direction is greater than the thickness of dunnage 6, the length of projection 3 is less than the length of rectangular through holes 7, wide in rectangular through holes 7 of growing up of projection 3, wide less than rectangular through holes 7 of projection 3 wide simultaneously, to guarantee that but adjustable lever 2 via through holes 7 are assemblied in supporting drum 1, after guaranteeing simultaneously adjustable lever 2 is rotated to an angle, adjustable lever 2 is set up on dunnage 6 by the projection 3 that is positioned at the certain altitude position, and then reach the purpose of regulating the parallels height by the projection 3 of selecting to be fit to height.
For saving material and the weight that alleviates parallels, adjustable lever 2 can adopt hollow structure.Simultaneously for workshop workman's operation, can offer erection opening 8 at supporting drum 1 and adjustable lever 2 corresponding position.
