Abstract
The utility model relates to the field of hoisting tools, particularly to a spring connecting mechanism and a lifting jack with the same. The spring connecting mechanism comprises an adjusting bolt, a piston rod pipe fitting and a spring, wherein external threads are formed on the adjusting bolt; internal threads are formed on the piston rod pipe fitting; the spring is arranged between the external thread and the internal thread; and the small diameter of the internal threads is larger than the large diameter of the external threads. The lifting jack comprises a base, a piston pump, an outer sleeve, an oil cylinder, a top cover and the spring connecting mechanism, wherein the piston pump and the outer sleeve are arranged on the base; the oil cylinder is arranged in the outer sleeve; the spring connecting mechanism is arranged in the oil cylinder; and the top cover is arranged at the top end of the oil cylinder. The spring connecting mechanism is convenient to operate and has a simple structure.
Description
Technical field
The utility model relates to the lifting gear field, specifically a kind of spring connecting mechanism and with the jack of this mechanism.
Background technology
Conventional is threaded, and is that the mutual interference engagement of inner outside thread thread reaches the bonded assembly effect, and this connection mode is used in and exists some drawbacks in the jack product; When two parts of screw rod and pipe fitting adopt when being threaded; Rotary screw plays adjustable range, because pipe fitting is long, so endoporus can not all be made negative thread; Can only be in the bottom long stepped hole of boring; This structure is not only processed relatively difficulty, has also brought unnecessary waste of material, has increased the cost of product; In addition, the smoothness when being threaded in rotation is not enough, and is stuck easily, so just makes troubles to operating this product.
The utility model content
The utility model provides a kind of spring connecting mechanism easy to operate, simple in structure and with the jack of this mechanism.
The utility model is realized through following technical proposals:
A kind of spring connecting mechanism; Comprise adjustment screw rod, piston rod pipe fitting and spring, said adjustment screw rod is provided with outside thread, and said piston rod pipe fitting is provided with negative thread; Said spring is located between said outside thread and the negative thread, and said negative thread path is greater than the big footpath of outside thread.
Said spring cross-sectional plane is circular or rectangle, and the shape of the thread form of said outside thread and negative thread and spring cross-sectional plane matches.
The pitch of said outside thread, negative thread and spring equates.
A kind of jack comprises base, plunger pump, overcoat, oil cylinder, top cap and spring connecting mechanism, and said plunger pump and being sheathed on outward on the base is provided with oil cylinder in the said overcoat, is provided with spring connecting mechanism in the said oil cylinder, and said top cap is located at the oil cylinder top.
Said plunger pump comprises the pump housing, pump core, presses hand and handle, and said pump core is located at pump housing inside, and said handle is connected with the pump core through pressing hand.
The beneficial effect that the utility model brought is:
In the utility model, said spring connecting mechanism comprises adjustment screw rod, piston rod pipe fitting and spring, and said spring is located between adjustment screw rod and the piston rod pipe fitting; Make both cooperations be in the running-fit state, this kind connection mode is rotated freely always, and can play adjustable range and the effect of tightening; In addition; This kind connection mode is more prone to processing, and has practiced thrift raw MAT'L, has reduced cost; Said jack comprises base, plunger pump, overcoat, oil cylinder, top cap and spring connecting mechanism, and said base is used for fixing plunger pump and overcoat, and said spring connecting mechanism is used for adjustable range and plays a part to tighten.
Description of drawings
Below in conjunction with accompanying drawing the utility model is done further explain.
Fig. 1 is the structural representation of the said spring connecting mechanism of the utility model;
Fig. 2 is the structural representation of the said jack of the utility model.
The cooresponding label of component names is following among the figure:
1, adjustment screw rod; 2, piston rod pipe fitting; 3, spring; 4, base; 5, plunger pump; 51, the pump housing; 52, pump core; 53, handle; 54, press hand; 6, overcoat; 7, oil cylinder; 8, top cap.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further to detail:
Embodiment as the said spring connecting mechanism of the utility model; As shown in Figure 1; Comprise adjustment screw rod 1, piston rod pipe fitting 2 and spring 3, said adjustment screw rod 1 is provided with outside thread, and said piston rod pipe fitting 2 is provided with negative thread; Said spring 3 is located between said outside thread and the negative thread, and said negative thread path is greater than the big footpath of outside thread.Said spring 3 is with adjustment screw rod 1 and cooperating of piston rod pipe fitting 2 be in the running-fit state all the time, and this kind connection mode is rotated freely, and can play adjustable range and the effect of tightening; In addition; This kind connection mode is more prone to processing, and has practiced thrift raw MAT'L, has reduced cost.
In the present embodiment, said spring 3 cross-sectional planes are circular, said outside thread and negative thread be shaped as semicircle, match with the shape of spring 3 cross-sectional planes.To guarantee that adjustment screw rod 1 and piston rod pipe fitting 2 rotate freely.
In the present embodiment, the pitch of said outside thread, negative thread and spring equates.To guarantee that adjustment screw rod 1 and piston rod pipe fitting 2 rotate freely.
Embodiment as the jack of the said band spring connecting mechanism of the utility model; As shown in Figure 2; Comprise base 4, plunger pump 5, overcoat 6, oil cylinder 7, top cap 8 and spring connecting mechanism, said plunger pump 5 is located on the base 4 with overcoat 6, is provided with oil cylinder 7 in the said overcoat 6; Be provided with spring connecting mechanism in the said oil cylinder 7, said top cap 8 is located at oil cylinder 7 tops.Be provided with piston rod pipe fitting 2 in the said oil cylinder 7, be provided with adjustment screw rod 1 in the piston rod pipe fitting 2, said piston rod pipe fitting 2, adjustment screw rod 1 and spring 3 are assembled together, and are combined into spring connecting mechanism.Said base 4 is used for fixing plunger pump 5, oil cylinder 7 and overcoat 6, and said spring connecting mechanism is used for adjustable range and plays a part to tighten.
In the present embodiment, said plunger pump 5 comprises the pump housing 51, pump core 52, handle 53 and presses hand 54, and said pump core 52 is located at the pump housing 51 inside, and said handle 53 is connected with pump core 52 through pressing hand 54.
Certainly, said spring cross-sectional plane also can be rectangle, and the shape of the shape of said outside thread and negative thread and spring cross-sectional plane matches and gets final product.So, also all within the utility model protection domain, give unnecessary details no longer one by one here.
