Abstract
The utility model relates to a lifting mechanism, in particular to the lifting mechanism with a single-action multistage cylinder. The lifting mechanism comprises a plurality of stages of cylinder tubes and thread plugs matched with the cylinder tubes. A plurality of outer grooves are disposed in the outer wall of each stage of cylinder tubes along the length direction. Each outer groove is fixedly provided with a guide strip. The guide strips protrude out of the outer walls of the cylinder tubes. Inner grooves for accommodating protruding portions of the guide strips are arranged in corresponding positions of the inner walls of the thread plugs. The guide strips are arranged on the outer walls of the cylinder tubes, and an internally-arranged guide mechanism is adopted. Compared with an externally-arranged guide mechanism, the lifting mechanism with the single-action multistage cylinder is capable of decreasing installation space of the guide mechanism, has little influence on the weight of the whole cylinder, and can also strengthen the strength of the cylinder.
Description
Technical field
The utility model relates to a kind of lifting mechanism, is specially a kind of lifting mechanism with single-acting multi-stage cylinder.
Background technology
Existing single-acting multi-stage cylinder can arrange a guiding mechanism mostly in order to prevent that cylinder from rotating in the process of stretching out on the market, and guiding mechanism generally all is external.The guiding mechanism of this external can increase the installing space of cylinder, and the weight of cylinder also can increase often simultaneously.In view of the foregoing, need to improve existing equipment at present.
The utility model content
For the shortcoming of above-mentioned prior art, the utility model provides the single-acting multi-stage cylinder lifting mechanism that a kind of weight is light, the one-way mechanism installing space is less.
The utility model solves the problems of the technologies described above by the following technical solutions and realizes:
A kind of lifting mechanism with single-acting multi-stage cylinder, comprise several grades of cylinder barrels and the plug screw that cooperates with cylinder barrel, the described cylinder barrel outer wall of every one-level has been opened several outer grooves along its length, be fixed with a gib block in each described outer groove, described gib block protrudes the outer wall of place cylinder barrel, is provided with in the corresponding position of plug screw inwall to hold the inner groovy that described gib block protrudes the position.
Further, described gib block is fixedly installed in the corresponding described outer groove by screw.
As preferably, described gib block is steel bar.
The utility model compared with prior art has following advantage: the utility model is provided with gib block at the cylinder barrel outer wall, what it adopted is built-in guiding mechanism, the guiding mechanism of relative external, the utility model can not only reduce the installing space of guiding mechanism, and less on whole cylinder weight impact, the while can also strengthen the intensity of cylinder.
Description of drawings
Fig. 1 is the structural representation of optimal way of the present utility model;
Fig. 2 is cross section of the present utility model enlarged diagram.
Among the figure: three grades of gib blocks 1, three grades of plug screws 2, three grades of cylinder barrels 3, secondary plug screw 4, secondary gib block 5, secondary cylinder barrel 6, one-level plug screw 7, one-level cylinder barrel 8, one-level gib block 9.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As depicted in figs. 1 and 2, described lifting mechanism comprises several grades of cylinder barrels and the plug screw that cooperates with cylinder barrel, specifically comprises three grades of plug screws 2, three grades of cylinder barrels 3, secondary plug screw 4, secondary cylinder barrel 6, one-level plug screw 7, one-level cylinder barrel 8; The described cylinder barrel outer wall of every one-level has been opened several outer grooves 10 along its length, be fixed with a gib block in each described outer groove, it is respectively three grades of gib blocks 1, secondary gib block 5, one-level gib block 9, described gib block all protrudes the outer wall of place cylinder barrel, is provided with in the corresponding position of every one-level plug screw inwall to hold the inner groovy 11 that described gib block protrudes the position.And the utility model adopts screw 12 connection modes that three grades of gib blocks 1, secondary gib block 5, one-level gib block 9 are separately fixed in three grades of cylinder barrels 3, secondary cylinder barrel 6, the outer groove of one-level cylinder barrel 8 each cylinder barrel.So not only connection is more firm, and can prevent that cylinder barrels at different levels from rotating in the process of stretching out.
In implementation process, gib block adopts steel bar, and the aluminum alloy material of its intensity ratio cylinder barrel will be got well, and therefore can increase the intensity of cylinder barrel.The utility model adopts built-in guiding mechanism, and the relative guiding mechanism of external can not only reduce the installing space of guiding mechanism, and less on whole cylinder weight impact, can also strengthen the intensity of cylinder simultaneously.
Above demonstration and described groundwork of the present utility model and principal character and advantage of the present utility model; the technical personnel of the industry should be understood; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the specification sheets just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications; these changes and improvements all fall in claimed the utility model scope, and the claimed scope of the utility model is defined by appending claims and equivalent thereof.
Claims (3)
