Abstract

The utility model discloses an improved structure of a wheel-type abdominal exerciser, which mainly comprises a handle, a roller component, a shaft center and a spring. The roller component includes at least one roller; each roller consists of a roller cover and a roller outer casing; the roller cover is connected onto the roller outer casing in a fastening manner; a through hole is arranged in the middle of the roller; a containing cavity is formed between the roller cover and the roller outer casing; the shaft center penetrates into the through hole in the middle of the roller through a bearing; handles are respectively connected to two ends of the shaft center; the spring is installed inside the containing cavity; one end of the spring is mounted on the inner lateral wall of the roller outer casing; and the other end of the spring is mounted on the shaft center. As the spring with a power assisting function is installed on each roller and can be twisted to generate elastic restoration force opposite to the direction of an original roller path when in exercising, a power assisting mechanism can greatly reduce the requirement of the exerciser on the self-condition of a user in exercising, is not easy to cause exercising injury, and is particularly applicable to beginners or people with poorer physical ability.

Description

The improvement structure of wheeled Stomach building device

Technical field

The utility model relates to a kind of fitness equipment, particularly relates to a kind of improvement structure of wheeled Stomach building device.

Background technology

Traditional wheeled Stomach building device mainly is made of roller (discus) and support (support arm), and common structure is the monocycly Stomach building device or is the dicycly Stomach building device.Because this exercising apparatus, needing the people to crouch lies, hand is held the support arm at Stomach building device two ends, by hand and belly strength, arched upward in people's back or set level, thereby realize exercise to abdominal muscle, but because the beginner is when carrying out this apparatus exercise, one lacks this exercise understanding, does not know whether the health of self can adapt to this apparatus, two, often there is not the counselor to assist by the side of on the side, in the process of taking exercise,, cause torn abdominal muscle easily because hand and belly strength are not enough.

The utility model content

The purpose of this utility model is to provide a kind of improvement structure with wheeled Stomach building device of power assisting device.

For achieving the above object, technical solution of the present utility model is:

The utility model is a kind of improvement structure of wheeled Stomach building device, and it mainly is made of handle, roll wheel assembly and axle center, and described roller is made up of hollow wheel shell body, and its middle part is provided with a through hole; Described axle center is placed through the middle part through hole of roller by bearing, and each connects handle respectively its two ends; It is characterized in that: it also comprises a spring, and this spring is installed in this containing cavity and an end of spring is articulated on the madial wall of housing, and its other end is articulated on the axle center.

Described spring is two-way torque spring or unidirectional volute spring steel disc.

Described roll wheel assembly is made of a roller, and described roller is by being nested with rotatable being socketed on the axle center of bearing in hole therein, and each connects handle respectively its two ends.

Described roll wheel assembly is made of two rollers and connecting rod; Described two rollers are respectively by being nested with rotatable being socketed on the axle center that is positioned at the connecting rod two ends of bearing in hole therein.

After adopting such scheme, the utility model has been installed the spring that plays the power-assisted effect at roller, and this spring can be twisted when taking exercise, and produces and the opposite elastic restoring force of former raceway direction, helps the practitioner to reset.Because the utility model has increased servomechanism, can reduce its requirement to person taking exercise's self-condition greatly, and be not easy to take place to temper damage, be particularly useful for the relatively poor relatively crowd of beginner or physical efficiency, as children and old man.

Below in conjunction with the drawings and specific embodiments the utility model is further described.

The specific embodiment

Embodiment 1:

As shown in Figure 1 and Figure 2, the utility model is a kind of improvement structure of wheeled Stomach building device, and it mainly is made up of nut chock plug 1, handle steel pipe 2, handle 3, axle center 4, two rollers 5, connecting rod 6, bearing 7, magnetic plungers 8.

Described two rollers 5 and connecting rod 6 constitute roll wheel assembly.The two ends of described connecting rod 6 are screwed onto respectively on the inner in axle center 4, and the outer end in axle center 4 and nut chock plug 1 are spirally connected, and handle steel pipe 2 is connected the outer end of nut chock plug 1, and handle 3 is socketed on the handle steel pipe 2; Described two rollers 5 are respectively by being nested with bearing 7 rotatable being socketed on the axle center 4 that is positioned at connecting rod 6 two ends in hole therein.

The wheel shell body of described roller 5 is made up of roller cap 51, roller shell 52, spring 53, dust cap 54.Described roller cap 51 snaps onto on the roller shell 52, and between forms a containing cavity; Described spring 53 is installed in this containing cavity and an end of spring 53 is articulated on the madial wall of roller shell 52, and its other end is articulated on the axle center 4, and this spring 53 is unidirectional volute spring steel disc; Described dust cap 54 is embedded on the sidewall of roller housing 52, and its mesopore is fixing is nested with in the axle center 4 outer end, produces interlock with axle center 4, thereby produces relative rotation with housing 52.

As shown in Figure 3, Figure 4, this embodiment 2 is substantially the same manner as Example 1, and different is:

Described connecting rod 6A is made up of handle 61A, handle steel pipe 62A, joint 63A, nut chock plug 64A.Described handle 61A is socketed on the handle steel pipe 62A, and the two ends of handle steel pipe 62A are attaching nut's chock plug 64A respectively, and joint 63A the inner is screwed onto on the nut chock plug 64A, and the outer end passes bearing 7A and axle center 4A is spirally connected.Spring 53A in the described roller 5A is two-way torque spring.

As shown in Figure 5, this embodiment 3 is substantially the same manner as Example 1, and different is: described roll wheel assembly is a roller 5B, and described roller 5B is by being nested with rotatable being socketed on the axle center of bearing in hole therein, and each connects handle 3B respectively the two ends, axle center.

Emphasis of the present utility model just is: the spring that the power-assisted effect has been set in roller.

The above, it only is the utility model preferred embodiment, so can not limit the scope that the utility model is implemented with this, i.e. the equivalence of doing according to the utility model claim and description changes and modifies, and all should still belong in the scope that the utility model patent contains.
