Abstract

The utility model relates to a training machine for swimming with an improved structure, particularly a training machine whose direction for manual operation is not limited to make arms and hand joints act more flexibly for increasing the installation performance of use and reducing the of motion when the utility model is used. A body can be fitted with the stretching of the hand parts for swinging and the characteristic training of the swimming can be sufficiently played mainly by that the wheel group of the utility model, which is wound with pulling wires, and the support frame of a noumenon are fixed by a rotating shaft and the barycenter of the body is used for driving a flat pad for swinging. The utility model is a new creation which has the advantages of beautiful appearance, firmness, safety, simple structure, and easy operation.

Description

The swimming instruction machine

The utility model relates to the fitness training sports equipment, refers to a kind of swimming instruction machine especially.

Common swimming instruction machine only is the motion of single direction at present, do not consider the non-single direction of rotation in each joint of human body in design as yet, and when design, complete consideration is not done at each position of physical activity, each function that should provide when this product uses is provided.The applicant gets a method of improving at above-mentioned shortcoming after doing repeatedly operation for swimming instruction machine commonly used, after repeatedly studying and improveing, can create a kind of structure improved swimming instruction machine of designing eventually.

Chang Yong swimming instruction machine now, consideration for security still has disappearance, under long-term situation about using, may cause permanent athletic injury to the user of swimming instruction machine, make the user of this swimming instruction machine can't reach the purpose of body-building by this equipment.

Main purpose of the present utility model provides a kind of swimming instruction machine, make manual direction unrestricted, and health cooperates water-skiing to swing, and foot and unfold whole body exercises, can do complete swimming instruction action, when using the utility model, can move more flexibly,, reduce the injury of motion in the hope of increasing the security of using.

The purpose of this utility model is achieved in that a kind of swimming instruction machine, mainly is made up of puller system, a movable plain cushion, two pulleys, two foot covers and a fixed bolster, and it is characterized in that: this puller system includes at least:

One torque spring is to be fixed on the holder, and the periphery circle is around stay cord;

Two wheels are to be uprightly to be fixed on the bracing frame, enclose around stay cord in interior;

Wherein, stay cord is wound on the torque spring, and the one end is fixed on the holder, and roller group location in the middle of the stay cord, the other end is connected with sash weight, the structure that formation can closely be adjusted, again, wheels are to engage with vertical direction with bracing frame, when the stay cord on being around in wheels is stressed, driven wheel group and rotating shaft rotation simultaneously, and be wound in the variation that the torque spring on the holder can produce different tight ness ratings, so that when its pulling force is replied, cushioned reaction force.

Be provided with the location group between movable plain cushion in the utility model and L type vertical shaft, be provided with extension spring in the group of location, it has shockproof and pins down movable plain cushion does and swings; And the pulley circle around same movable rope in interior, the movable rope two ends are each with delineation position, a location, make movable rope be the parallel mode activity; Described in addition two foot covers are to be connected with the movable rope two ends, can cooperate both feet and the do activity; And fixed bolster and fixed bolster pillar are connected on the L type vertical shaft, constitute the setting of an auxiliary movement.

It mainly is to drive wheels synchronously when utilizing stay cord to be subjected to the external force pulling for the utility model, also can drive wheels and do to vacillate now to the left, now to the right in the pulling stay cord, is done action in the same way so that stay cord cooperates application of force direction; In addition, cooperate the action of hand, health also waves along the action of hand; Again, establish the two foot collars and can penetrate foot, do the action of fetching water; This reality is novel make operator's action can be more smooth really, to increase the security on using.

For enabling that the purpose of this utility model, feature and effect are had further understanding, now by following specific embodiment, and conjunction with figs., the utility model is described in detail, illustrate as the back:

Fig. 1: be three-dimensional combination figure of the present utility model.

Fig. 2: be an embodiment of the present utility model.

Fig. 3: be another embodiment of the present utility model.

Fig. 4: be another embodiment of the present utility model.

Fig. 5: be to use schematic diagram of the present utility model.

As shown in Figure 1, puller system of the present utility model mainly is that bracing frame 70 both sides respectively connect a power seat 62, respectively establishes a torque spring 60 on power seat 62, is that each is wound in its periphery with a stay cord 61, and is a sash weight 41 at stay cord 61 other ends; Connect a sash weight 41 and leader 20 simultaneously with a clasp 30, and the direction of action of stay cord 61 is by wheels 40 controls, as shown in Figure 2 again.Again, wheels 40 are fixed as one with rotating shaft 52, make the direction of action of stay cord be polytropism, as shown in Figure 3.

Seeing also Fig. 2, is respectively to hold leader 20 simultaneously with straight-line state tractive stay cord 61 for two hands, makes stay cord 61 be subjected to a pulling force, again, pulling force reaches torque spring 60, discharges the part stay cord 61 that is wound in its periphery by torque spring 60 according to stressed size again, makes both hands can make extensional motion.

Seeing also Fig. 3, is respectively to hold leader 20 for two hands, is that the center rotates with a rotating shaft 52 on the other hand, and another hand is that the center assistant is done oblique movement with the slip of clasp 30 with rotating shaft 52; Adjust the length that motion bar 90 can be adjusted the swimming instruction machine according to the build height by the adjustment button on the fixed bar 80 again.

As shown in Figure 4, three bottom portions respectively establish certain hyte 130 before, during and after the movable plain cushion 110 of the present utility model, connect movable plain cushion 110 and L type vertical shaft 140, in addition, six extension springs 111 are arranged, connect location group 130 and L type vertical shaft 140, be to be vibration abatement and connection L type vertical shaft 140, be for vibration abatement and connection L type vertical shaft 140,, can utilize body weight that movable plain cushion 110 is swung by said structure; Extend a fixed bolster pillar 114 in L type vertical shaft 140 turning points, in order to prop up fixed bolster 115 again.

As shown in the figure, the two-phase contraposition at L type vertical shaft 140 nearly motion bars of the present utility model 90 places installs two centring rings 112, be to be inserted in movable rope 116 in two centring rings 112, establish two pulleys 117 in set round bar 120 near near the both ends of the surface again, each and the parallel combination in the two ends of movable rope 116 make movable rope 116 slide by pulley 117, again, the movable rope two ends respectively are a foot cover 118, so by foot's swing movable rope 116 is slided.

Seeing also Fig. 5, is for operating embodiment of the present utility model.

In sum, the utility model has reached the effect of expection, and only the above person only is preferred embodiment of the present utility model, and has reached the effect of practical application, such as the equalization of doing according to technical solutions of the utility model changes and modifies, and all should still belong in the technical solutions of the utility model scope.
