Abstract

Disclosed is a safety device of a headstand machine lying plate. A frame body of a headstand machine comprises two parallel herringbone supports. Two rotating shafts are installed on pivot joint parts on the top of the supports in a symmetrical mode, a connecting rod is placed under each rotating shaft, the two connecting rods are respectively connected with two ends of a cross-bar installed on the back portion of the lying plate, at least one rotating shaft is provided with a torsional spring, a bending foot at one end of the each torsional spring is attached to the side of a top fulcrum bar of each support, and a bending foot at the other end of each torsional spring is attached to each rotating connecting rod. When the headstand machine provided with the safety device of the headstand machine lying plate is in use, the torsional springs are added to the supports and the rotating shafts used for enabling the lying plate to rotate, and therefore during an overturning process of the lying plate in an up-and-down mode , restoring force of the torsional springs can be used for buffering and as an assistant force when the connecting rods are moved to two ends, and force application and movement of a user on the lying plate can be more safe and relaxed.

Description

The safety device of upside down machine service creeper

Technical field

The utility model relates to a kind of sports equipment, relates in particular a kind of safety device of upside down machine service creeper.

Background technology

The existing quite a while is finished in the upside down machine development, it belongs to a kind of exercise and fitness equipment that relaxes, common upside down machine has generally comprised a support body, a grip device, a service creeper and foot's clamping apparatus, support body includes two parallel herringbones, service creeper is articulated in the top of support and is rotatably connected between the two stands, the user loosens health by standing upside down at upside down machine, reaches to stimulate circulation, eliminate and ache and train power of waist.

The user is when making stretching, extension and extensional motion, because being under the unsettled state take the pivoting part of support body top end as fulcrum, service creeper swings, the user realizes standing upside down and digging in the swing at service creeper in dependence self strength and arm drive, for can not skillfully using the weak user of upside down machine or strength, it in use, very painstaking when standing upside down or will upwards erect, in rotation process also can owing to its be not subjected to self control and in the process of gravity center shift, there is not psychologically the sense of security, rise rapidly and fall can make also that the user is to have unsafe hidden danger in operation, be unfavorable for standing upside down the proceeding of motion, it really has in addition improved necessity.

The utility model content

The purpose of this utility model is to provide a kind of upside down machine service creeper safety device, the user in the extension movements of standing upside down and erecting, can be easily again safer execution.

In order to reach above-mentioned purpose, solution of the present utility model is:

A kind of safety device of upside down machine service creeper, the support body of upside down machine includes two parallel herringbones, two turn axisymmetric is disposed on the articulated section of propping up top of the trellis, the rotating shaft below is equipped with a connecting rod, two connecting rods are connected to cross bar two ends that are installed on the service creeper back, be arranged with torsion spring at least one rotating shaft, the closing of an end of torsion spring folding pin on the side of a top of the trellis pole, other end folding pin then closing on the connecting rod that rotates.

Connected by an antiskid bar between the bottom of described two parallel supports, and bridge joint has a middle part crosspiece bar between the two stands.

After adopting said structure, upside down machine of the present utility model in use, because torsion spring has been set up in the rotating shaft in support and service creeper rotation, service creeper is in switching process back and forth, the restoring force that utilizes torsion spring plays certain buffering and power-assisted effect in link motion during to both ends, can make user's force application movement safety and easily more on service creeper.

Description of drawings

Fig. 1 is the structural representation one of the utility model on upside down machine;

Fig. 2 is the structural representation two of the utility model on upside down machine;

Fig. 3 is the structural representation three of the utility model on upside down machine.

The specific embodiment

In order further to explain the technical solution of the utility model, the utility model is elaborated below by specific embodiment.

Extremely shown in Figure 3 in conjunction with Fig. 1, upside down machine includes a support body 10, a grip device 2, a service creeper 3 and foot's clamping apparatus 4, support body 10 includes two parallel herringbones 1 and even combines, service creeper 3 is articulated in the top end of support 1 and is rotatably connected between the two stands 1, grip device 2 comprises the arc handle 21 that is connected on the two stands, connected by an antiskid bar 11 between the bottom of two parallel supports 1, and bridge joint has a middle part crosspiece bar 12 between the two stands.

On the herringbone 1 of upside down machine, on the top of each support 1, the top that is lambdoid support is provided with an articulated section 13, on the articulated section that is disposed at this support 1 top of two rotating shafts, 5 symmetries, rotating shaft 5 belows are equipped with a connecting rod 51, and be provided with a cross bar 31 at the back of service creeper 3, the two ends of cross bar 31 are connected on this two connecting rod 51, thereby realize that service creeper 3 is rotating between two stands 1 take rotating shaft 5 as fulcrum under the connection function of connecting rod 51, the user couches and realizes the motion of standing upside down at service creeper 3.

Main improvements of the present utility model are, are arranged with a torsion spring 6 at least one rotating shaft 5, and the rear end folding pin of this torsion spring 6 leans (not shown) on the pole side at support 1 top, and 61 closings of front end folding pin are on the connecting rod 51 that rotates.

As shown in Figure 1, 2, thus service creeper 3 when rotating, connecting rod 51 is together with rotating shaft 5 activities, when service creeper 3 stands upside down downwards and upwards turns over when erecting, it is mobile during soon to the bottom to stand upside down at service creeper, state shown in Figure 1, because the twisting force that torsion spring 6 is certain is so can reach the effect of mitigation in motion process.And need to overturn when erecting after the end of standing upside down, the user can erect comparatively easily by the restoring force of torsion spring 6, in erecting process, connecting rod 51 rotates take rotating shaft 5 as fulcrum, connecting rod 51 moves counterclockwise, the front end folding pin 61 that goes to torsion spring with its against the time rotation process gradually stable after, state shown in Figure 2, erect to service creeper, the user slightly after the application of force, it can do reverse motion again, and the restoring force of torsion spring 6 plays certain buffering and power-assisted effect in link motion during to both ends, makes user's force application movement safety and easily more on service creeper.

Above-described embodiment and graphic and non-limiting product form of the present utility model and style, any person of an ordinary skill in the technical field all should be considered as not breaking away from patent category of the present utility model to its suitable variation or modification of doing.
