Abstract

The invention belongs to the field of sports equipment, and relates to an adjustable and controllable strength trainer characterized by pulling a weight during half-squat and stand. The strength trainer is characterized in that a shock-reducing rubber blanket is placed on the ground; a weight is placed on a shock-reducing rubber blanket; inner sides of four pulling handles are welded and connected onto the outer side of the lower end of an up-lifting rack; four castors are hinged at the lower end of the up-lifting rack through four shafts respectively and placed on the ground; a first rubber blanket is pasted and connected with the upper middle part of the weight; weight scale values corresponding to the weight are engraved on the up-lifting rack; the lower part of the up-lifting rack is placed on the first rubber blanket; a second rubber blanket is fixedly connected onto the inner upper side of a sliding sleeve through a rivet; the sliding sleeve is buckled on the up-lifting rack; and the two sides of the sliding sleeve are fastened and connected with the weight through four screws. Suitable pulling weight can be found out through moving the up-lifting rack forwards and backwards, so that the problem that the conventional pulling weight is not easy to adjust and control can be solved; when the trainer is used during the process of squat and stand, the muscles of lower limbs are in the state of isotonic contraction; and the pulling handles are arranged at the two ends of the trainer to enable training at either end to be realized conveniently.

Description

The strengthening exercise device that adjustable semi-crouch stands and lifts weight

Technical field

The invention belongs to field of sports equipment, relate to the strengthening exercise device that a kind of adjustable semi-crouch stands and lifts weight.

Background technology

The exercise semi-crouch both hands that stand lift the effect that weight has development upper and lower extremities muscle of trunk strength.The existing semi-crouch both hands that stand lift the weight strengthening exercise and have following problem: a, lift barbell and select suitable weight dismounting disc process to waste time and energy; B, the weight that lifts associating apparatus pouring weight are at interval big or lift certain weight and be difficult for finding suitable oneself required weight; C, lift the power value that electronic scale can convenient demonstration lifts, but since lower limb do not stand can, do the muscle isometric contraction for a long time and be unfavorable for developing the elasticity of muscle.Eventually the above conveniently finds the suitable own required weight that lifts, and realizes that the muscle isotonic contraction is to design the semi-crouch problem that the strengthening exercise device need solve that stands.

Summary of the invention

In order to solve the problem that exists in the above-mentioned background technology, the invention provides the strengthening exercise device that a kind of adjustable semi-crouch stands and lifts weight, it is made of following technical scheme: place the yielding rubber pad on the ground, pouring weight is placed on the yielding rubber pad, four lift the handle inboard and are welded to connect and are lifting the frame lower end outside, four castors are hinged on respectively by four axles and lift the frame lower end and place ground, gluing connection first rubber cushion in middle part on pouring weight, lift and be carved with the weight scale numerical value corresponding with it above the frame, lift and place on first rubber cushion below the frame, upside is by fixedly connected second rubber cushion of pulling rivet in sliding sleeve, sliding sleeve is buckled in and lifts above the frame, and the sliding sleeve both sides are fastenedly connected by four screws and pouring weight.

This exercising machine is compared its beneficial effect with the weight mode that lifts that the above-mentioned background technology is mentioned in the past: a, move forward and backward and lift frame and can be convenient find out the weight that lifts that is fit to oneself, solved and lifted the not problem of easy-regulating of weight in the past; B, use its lower limb muscles work of process that stands of this exercising machine semi-crouch to be isotonic contraction, be conducive to develop the elasticity of muscle, avoided lifting electronic scale and done the lower limb situation that the muscle isometric contraction influences the elasticity of muscle that do not stand for a long time and take place; C, this exercising machine two ends setting lift handle and can convenient practise at any end.

Description of drawings

Below in conjunction with the drawings and specific embodiments the present invention is done explanation in further detail.

Fig. 1 is that the stand master of the strengthening exercise device that lifts weight of adjustable semi-crouch looks sketch;

Fig. 2 is that sketch is looked on the left side of Fig. 1;

Fig. 3 is the diagrammatic top view of Fig. 1;

Fig. 4 is the part amplification simplified schematic diagram that Fig. 3 lifts scale numerical value above the frame both sides;

Fig. 5 is Fig. 1 pouring weight is lifted light weight at far-end simplified schematic diagram;

Fig. 6 is that Fig. 1 pouring weight is lifted the simplified schematic diagram of heavy amount at near-end.

The specific embodiment

With reference to accompanying drawing, 9 place yielding rubber pad 2 on ground, pouring weight 1 is placed on the yielding rubber pad, four lift handle 5 inboards and are welded to connect and are lifting the frame 6 lower ends outsides, four castors 3 are hinged on respectively by four axles 4 and lift the frame lower end and place ground, gluing connection first rubber cushion 11 in middle part on pouring weight, lift and be carved with the weight scale numerical value 13 corresponding with it above the frame, lift and place on first rubber cushion below the frame, upside is by pulling rivet 12 fixedly connected second rubber cushions 10 in sliding sleeve 8, sliding sleeve is buckled in and lifts above the frame, and the sliding sleeve both sides are fastenedly connected by four screws 7 and pouring weight.

When using this exercising machine, practitioner's semi-crouch two hands are held respectively and are lifted handle, move forward and backward and lift frame, lift frame in the test and find out and be fit to weight and can practise.Pouring weight is that minimum is lifted weight away from lifting handle one side, as shown in Figure 5; Pouring weight is that maximum is lifted weight near lifting handle one side, as shown in Figure 6, is the weight that the both hands that stand lift along corresponding scale numerical value behind the sliding sleeve.

Claims

1. strengthening exercise device that regulatable semi-crouch stands and lifts weight, it is characterized in that: place the yielding rubber pad on the ground, pouring weight is placed on the yielding rubber pad, four lift the handle inboard and are welded to connect and are lifting the frame lower end outside, four castors are hinged on respectively by four axles and lift the frame lower end and place ground, gluing connection first rubber cushion in middle part on pouring weight, lift and be carved with the weight scale numerical value corresponding with it above the frame, lift and place on first rubber cushion below the frame, upside is by fixedly connected second rubber cushion of pulling rivet in sliding sleeve, sliding sleeve is buckled in and lifts above the frame, and the sliding sleeve both sides are fastenedly connected by four screws and pouring weight.
