Description

Technical Field

[0001] The utility model relates to the field of fitness equipment, in particular to a multifunctional sit-up assistor. Background Art

[0002] With the increasing improvement of people's living standards, more and more people pay attention to physical health, and home exercise has become a way for many people to keep fit. Sit-ups are a common exercise action during exercise. In order to assist this kind of exercise action, many products of sit-up assistors have appeared on the market. The sit-up assistors on the market have a simple structure and a single function, and cannot assist other exercise actions, especially cannot be used as a waist-twisting disc to assist waist-twisting exercises. How to design a sit-up assistor with a waist-twisting function or other functions is a problem that designers are yet to solve. Content of the Utility Model

[0003] To solve the above problems, the utility model provides a multifunctional sit-up assistor, which solves the problem of the single function of the sit-up assistor.

[0004] The technical solution adopted by the utility model is as follows: a multifunctional sit-up assistor, including a base, a suction cup, a connecting piece, and a cam handle. The connecting piece penetrates through the base. The upper end of the connecting piece is rotatably connected to the cam handle, and the lower end of the connecting piece is connected to the suction cup. A cavity is arranged at the bottom of the base, and the cavity is located above the suction cup. The assistor further includes a waist-twisting disc. A support rod is detachably connected to the waist-twisting disc. Stop rods are arranged on both sides of the support rod. The waist-twisting disc is rotatably connected to the base. An arc-shaped avoidance space for placing the cam handle is arranged on the waist-twisting disc.

[0005] Through the above technical solution, when the base is fixed to the ground by using the suction cup, the user can either install the support rod and use the stop rods for sit-up exercises, or remove the support rod and directly use the waist-twisting disc for waist-twisting exercises. The sit-up assistor of the utility model adds the function of the waist-twisting disc, making its function more abundant; the setting of the arc-shaped avoidance space enables the waist-twisting disc to avoid the cam handle, making it easier for the user to use the cam handle. The arc-shaped avoidance space also enables the waist-twisting disc to have a certain movement angle without being in contact with and limited by the cam handle, so as to facilitate the use of the waist-twisting disc.

[0006] Furthermore, the cam handle is integrally arc-shaped, and the cam handle can be switched between an open state and a closed state. When in the closed state, the cam handle lies on the top surface of the base. The cam handle drives part of the suction cup away from the ground through the connecting piece to form negative pressure. The cam handle is located in the arc-shaped avoidance space, and the width of the cam handle is adapted to the width of the arc-shaped avoidance space.

[0007] Through the above technical solution, the cam handle is in an arc shape that matches the arc-shaped avoidance gap, so that the width of the arc-shaped avoidance gap can be designed to be smaller while the cam handle has the same width, making the twisting waist plate structure more compact and firm.

[0008] Furthermore, the number of the suction cup, the connecting piece and the cam handle are two each, and the two suction cups are symmetrically arranged.

[0009] Through the above technical solution, the suction force provided by the suction cup is more uniform. When the angle of the waist twisting plate is adjusted so that the extension direction of the barrier rod is the same as the parallel distribution direction of the two suction cups, the adsorption effect of the suction cup and the ground is less likely to be destroyed when the user uses the barrier rod to perform sit-ups. The user can perform more intense sit-ups or can bear a greater weight for sit-ups.

[0010] Furthermore, a fixing plate is provided in the middle of the arc-shaped avoidance gap, and the fixing plate is connected between the inner walls on both sides of the arc-shaped avoidance gap; the cam handle includes an integrally formed cam portion and a handle portion, and the cam portion is rotatably connected to the connecting piece, and the height of each point on the handle portion is always higher than the height of the fixing plate.

[0011] Through the above technical solution, the setting of the fixed plate enhances the structural strength of the arc-shaped avoidance gap of the twisting waist disc, making the twisting waist disc not easy to deform or exercise, thereby extending its service life; the height of the fixed plate is set reasonably to avoid the fixed plate abutting against the handle and limiting the rotatable angle of the twisting waist disc.

[0012] Furthermore, a counting display is provided on the waist twisting disk, and a magnetic sensor is electrically connected to the counting display. A magnetic block is fixedly connected to the base, and the magnetic sensor is used to sense the number of times the magnetic block passes and transmit an electrical signal to the counting display.

[0013] The above technical solution makes it convenient for users to count the number of times they twist their waist, so that they can control the intensity of exercise.

[0014] Furthermore, a connecting tube is fixedly arranged on the twisting waist plate, the connecting tube is vertically arranged, and at least two gear holes are opened on the connecting tube, and the gear holes are distributed along the length direction of the connecting tube; the support rod is hollow, and an elastic part is arranged inside the support rod, and a clamping protrusion is connected to the elastic part, and an avoidance hole for the clamping protrusion to extend out is opened on the support rod, and the clamping protrusion is selectively clamped with one of the gear holes.

[0015] Through the above technical solution, when the clamping protrusion is connected to the gear holes with different heights, the installation height of the support rod can be adjusted, so that the blocking rod is installed at an appropriate height, facilitating users of different body types to use the sit-up assist device of the present utility model.

[0016] Further, a first spring is vertically connected to the support rod, and a punching ball is connected to the top of the first spring.

[0017] Through the above technical solution, the punching exercise function is added, further enriching the functions of the present utility model.

[0018] Further, it further includes a buckle, a tension rope and a handle. The buckle and the handle are both connected to the tension rope; a fixing ring is provided on the support rod and / or the blocking rod, and the buckle is connected to the fixing ring.

[0019] Through the above technical solution, the stretching exercise function is added, further enriching the functions of the present utility model.

[0020] Further, an installation groove is provided at the bottom of the waist-twisting disc, a circular slide rail is provided on the base, or a circular slide rail is provided at the bottom of the waist-twisting disc and an installation groove is provided on the base; it further includes a plurality of round beads, and the round beads are connected in the installation groove and are slidably connected to the circular slide rail.

[0021] Through the above technical solution, by using the cooperation of the round beads and the circular slide rail, the rotation between the base and the waist-twisting disc is made smoother.

[0022] Further, a second spring is sleeved on the connecting member, the top of the second spring extends into the cavity portion and abuts against the base, and the second spring abuts against the suction cup.

[0023] Through the above technical solution, the setting of the second spring can help the suction cup quickly return to the shape state before adsorption, facilitating the repeated use of the suction cup. Description of the Drawings
