Abstract
The utility model discloses a hand spring exerciser comprising two tensile sheets which are made of aluminum alloy and which are in U shapes. The left ends is provided with openings, the right ends of the tensile sheets are provided with clamping portions in a square shape, the sides of the clamping portions are provided with a plurality of positioning holes which are stepped, positioning members are arranged in the positioning holes in a matched manner and are clamped on the stepped faces of the positioning holes, and tensile springs are arranged between the positioning members of the tensile sheets in a matched manner; rubber plugs are arranged in the clamping portions in a matched manner to press against the positioning members, and the top of the rubber plug is provided with a pulling ring; screwed holes are formed in the upper and lower ends of the tensile sheets, a screw is arranged between the two screwed holes in a matched manner, and a sponge sleeve sleeves the part of the screw located in the tensile sheets. The hand spring exerciser has high tensile resistance, and is convenient to maintain and low in cost.
Description
Technical field
The utility model relates to a kind of hand chest expander.
Background technology
Existing hand chest expander, the fixed form of its tension spring mostly is hanging-ring type, the fixed form of this structure, frequent stressed after, suspension ring can produce distortion and even fracture, because its drag ability is not high, stressed concentrating on a point, the position of hand effect also can fracture after stressed simultaneously, after fractureing, need again to purchase chest expander, use cost is higher.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of hand chest expander, and the stretching resistance ability of this device is stronger, safeguards more simultaneously, and use cost is lower.
For addressing the above problem, the utility model adopts following technical scheme:
A kind of hand chest expander, comprise the pulling force sheet that two aluminium alloys are made, described pulling force sheet is U font, its left end has opening, described pulling force sheet right-hand member has the clamping part of a square shape, this clamping part lower end closed, top has opening, described clamping part offers several locating holes on that side away from pulling force sheet, described locating hole is shoulder hole, in described locating hole, be combined with keeper, this keeper is stuck on the cascaded surface of locating hole, between keeper on two pulling force sheets, be combined with tension spring, in described clamping part, be provided with rubber stopper, this rubber stopper is engaged in after clamping part, offset with described keeper, described rubber stopper top is provided with draw ring, described pulling force sheet upper, on lower end, correspondence is provided with screwed hole, between two screwed holes, be combined with threaded rod, described threaded rod is positioned in that part of pulling force sheet and is arranged with sponges cover, described threaded rod is positioned on the two ends of pulling force sheet outside and is provided with nut, nut spiral is to offseting with described pulling force sheet.
As preferred technical scheme, the length of described rubber stopper is greater than the degree of depth of clamping part inside.
As preferred technical scheme, on described sponges cover medial surface, be provided with the finger section corresponding with human finger, on lateral surface, be provided with the tiger's jaw portion corresponding with human body tiger's jaw.
The beneficial effects of the utility model are: pass through clamping part, make the stressed of keeper be transformed into face by point, therefore stressed comparatively even to clamping part, increased the stress-bearing capability of clamping part, the position of the hand application of force adopts the form that threaded rod coordinates with sponges cover simultaneously, permanent stressed, causes after threaded rod distortion, only need to change threaded rod, therefore use cost is comparatively cheap, and the assembling of this device is comparatively simple, is applicable to promoting the use of.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is front view of the present utility model;
Fig. 2 is top view of the present utility model.
The specific embodiment
below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that, protection domain of the present utility model is made to more explicit defining.
Consult a kind of hand chest expander shown in Fig. 1 and Fig. 2, comprise the pulling force sheet 1 that two aluminium alloys are made, described pulling force sheet 1 is U font, its left end has opening, described pulling force sheet 1 right-hand member has the clamping part 2 of a square shape, these clamping part 2 lower end closed, top has opening, described clamping part 2 offers several locating holes 201 on that side away from pulling force sheet 1, described locating hole 201 is shoulder hole, in described locating hole 201, be combined with keeper 3, this keeper 3 is stuck on the cascaded surface of locating hole 201, between keeper 3 on two pulling force sheets 1, be combined with tension spring 4, in described clamping part 2, be provided with rubber stopper 5, this rubber stopper 5 is engaged in after clamping part 2, offset with described keeper 3, described rubber stopper 5 tops are provided with draw ring 501, described pulling force sheet 1 upper, on lower end, correspondence is provided with screwed hole, between two screwed holes, be combined with threaded rod 6, described threaded rod 6 is positioned in that part of pulling force sheet 1 and is arranged with sponges cover 7, described threaded rod 6 is positioned on the two ends of pulling force sheet 1 outside and is provided with nut 8, nut 8 spirals are to offseting with described pulling force sheet 1.
A preferred embodiment in the utility model, the length of described rubber stopper 5 is greater than the degree of depth of clamping part 2 inside.
A preferred embodiment in the utility model, is provided with the finger section corresponding with human finger 701 on described sponges cover 7 medial surfaces, is provided with the tiger's jaw portion 702 corresponding with human body tiger's jaw on lateral surface.
The beneficial effects of the utility model are: pass through clamping part, make the stressed of keeper be transformed into face by point, therefore stressed comparatively even to clamping part, increased the stress-bearing capability of clamping part, the position of the hand application of force adopts the form that threaded rod coordinates with sponges cover simultaneously, permanent stressed, causes after threaded rod distortion, only need to change threaded rod, therefore use cost is comparatively cheap, and the assembling of this device is comparatively simple, is applicable to promoting the use of.
The above, be only the specific embodiment of the present utility model, but protection domain of the present utility model is not limited to this, and any variation of expecting without creative work or replacement, within all should being encompassed in protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claims were limited.
