Abstract
The utility model belongs to the field of jacks, and particularly relates to a mechanical jack. The mechanical jack comprises an ejector rod with threads at the lower end, and a pedestal. The mechanical jack further comprises an adjusting seat, wherein internal holes of the adjusting seat are connected with the threads at the lower end of the ejector rod; an external circle of the adjusting seat is connected with the internal holes of the pedestal by virtue of the threads; the adjusting seat is higher than the pedestal; and an exposed part of the external circle of the adjusting seat is fastened by virtue of a fastening nut. The mechanical jack provided by the utility model has the beneficial effects of being simple in structure, and safe in use, and has the capacity of adjusting the height of the jack in two stages; thus, the demands on commonly adjusting the jacking height and greatly adjusting the jacking height can be met.
Description
Technical field
The utility model belongs to the jack field, is specifically related to a kind of mechanical jack.
Background technology
The standard machinery jack is made up of a base and the threaded push rod in lower end, and the height of its jacking receives the limitation in height of push rod.When carrying out adjustment by a relatively large margin because of workpiece shape difference; At this moment adjust push rod and just satisfied not requirement, can only take the provisional measure of pad parallels below base to solve, both the ten minutes trouble; Also cause the instability of bottom support easily, thereby bring out safety misadventure.
Summary of the invention
The utility model technical matters to be solved is that a kind of mechanical jack that can regulate top lifting height by a relatively large margin will be provided.
For solving the problems of the technologies described above, the technical scheme that the utility model divides is:
A kind of mechanical jack comprises threaded push rod in lower end and base, also comprises the adjustment seat, and the endoporus of adjustment seat is connected with the base inner hole thread with the cylindrical that the lower end of push rod was threaded, adjusted seat.
Described mechanical jack, the adjustment seat exceeds base, and the exposed parts of the cylindrical of adjustment seat is fastening by clamp nut.
The outer round belt annular knurl of said clamp nut.
The beneficial effect of the utility model isSimple in structure, safe in utilization, can carry out the two-stage adjustment to the jack height, satisfied the general demand of adjusting top lifting height by a relatively large margin that reaches.
Description of drawings
Further specify below in conjunction with accompanying drawing and the specific embodiment technical scheme the utility model.
Fig. 1 is the structural representation of this use new embodiment mechanical jack.
The specific embodiment
A kind of mechanical jack as shown in Figure 1; Comprise the threaded push rod in lower end 1, adjustment seat 2, clamp nut 3 and base 4; The endoporus of adjustment seat 2 is threaded with the lower end of push rod 1, and the cylindrical of adjustment seat 2 is connected with base 4 inner hole threads, and adjustment seat 2 exceeds base 4; The exposed parts of the cylindrical of adjustment seat 2 is fastening by clamp nut 3, the outer round belt annular knurl of clamp nut 3.
In the ordinary course of things, it is just passable only to adjust push rod 1, runs into when adjusting significantly, can earlier clamp nut 3 be unclamped, and the height of adjustment adjustment seat 2 behind the height that arrival requires, is tightened nut 3 again, also can finely tune push rod 1 at last.
Present embodimentMechanical jack is simple in structure, safe in utilization, can carry out the two-stage adjustment to the jack height, has satisfied the general demand of adjusting top lifting height by a relatively large margin that reaches.
It should be noted last that; The above specific embodiment is only unrestricted in order to the technical scheme of explanation the utility model; Although with reference to preferred embodiment the utility model is specified, those of ordinary skill in the art should be appreciated that and can make amendment or be equal to replacement the technical scheme of the utility model; And not breaking away from the spirit and the scope of the utility model technical scheme, it all should be encompassed in the middle of the claim scope of the utility model.
