Description

Spring sit-up exerciser

technical field

The utility model relates to a sports apparatus, in particular to a spring-type sit-up exerciser for sit-up exercise. the

Background technique

At present, with the improvement of people's living standards, more and more people consume more high-energy foods in their diets. The nutritional imbalance in the diet makes the food intake exceed the needs of the body, resulting in excessive heat generation in the body and reduced exercise time. Energy expenditure is reduced, thus, leading to excess body weight. The most prone to gaining weight is the waist and abdomen where fat is easy to accumulate. Using sit-ups to lose excess fat in the waist and abdomen is a more effective method, but using the traditional method of doing sit-ups on a flat mat requires the cooperation of one's own ability and persistence to achieve the goal of fat loss . People with poor physical fitness or certain diseases cannot use this method to reduce fat. Even if they barely do a few sit-ups, they cannot achieve the effect of reducing fat. In addition, when the human body performs sit-up exercises on a flat mat, the trunk of the body pivots around the hips and moves toward the knees. After the trunk reaches the vertical position of the upper body, it returns to the original starting position and completes a cycle. sports. During each exercise cycle, the back and sacrum are subjected to a very large compression force. If the pressure is repeatedly applied at a high frequency, it is very easy to cause sports injuries to the back and sacrum. the

Contents of the invention

In order to overcome above-mentioned deficiency, the utility model proposes a kind of spring type sit-ups trainer, and this trainer is provided with spring and lifter, when doing sit-ups with this trainer, can reduce the compression force at back and sacrum place, The exerciser can easily perform sit-up exercises with the help of external force, and can also avoid sports injuries, so as to meet the needs of the public and athletes for abdominal fat reduction training. the

The technical solution adopted by the utility model is: a spring type sit-up exerciser, the main structure of the exerciser is connected by the upper bed board and the lower bed board through hinges, the lower end of the upper bed board is connected with the upper end of the spring, and the lower end of the spring is connected with the inclined plate The upper end is connected, the rear part of the lower end of the sloping plate is connected with the upper middle part of the bottom plate through a hinge, the lower front part of the sloping plate is respectively connected with the upper ends of the two lifters, the lower ends of the two lifters are respectively connected with the upper front part of the bottom plate, and the upper bottom edge of the lower bed plate The lower end of the lower bed plate is connected with the upper ends of the four bed legs by screws and nuts respectively, and the lower ends of the four bed legs are respectively connected with the upper end of the base plate by screws and nuts. the

The upper ends of the lower bed boards are respectively connected with one ends of the two fixing bands through screws and nuts, and the other ends of the two fixing bands are respectively connected with the upper ends of the lower bed boards through locking switches. the

A hollow groove is provided in the middle of the connection between the upper bed board and the lower bed board. the

The beneficial effect of the utility model is that: the spring under the upper bed board of the exerciser can not only generate the driving force for the upper body to sit up, but also play a buffer role when the upper body is restored, so that the exerciser can easily Continuously complete sit-ups without causing sports injuries. Even patients with poor physical fitness or in the recovery period can complete the exercises more easily; there is a lifter between the inclined board and the bottom board to adjust the angle of the upper board; there is a hollow groove in the middle of the connection between the upper board and the lower board, It can keep the sacrum free from pressure, thereby effectively avoiding damage to the sacrum caused by high-intensity sit-ups. In addition, there is a baffle at the end of the lower bed board, and the pedal baffle can prevent the body from sliding down during practice. In a word, the exerciser can be used for sit-ups without effort, which can not only improve the interest of practitioners, but also meet the fitness needs of the public and professional athletes. It has practical significance for improving the practice effect of sit-ups. the

Description of drawings

Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described in further detail. the

Fig. 1 is a three-dimensional schematic diagram of a spring type sit-ups exerciser. the

Detailed ways

The spring type sit-up exercise device proposed by the utility model adopts the following structure, as shown in Figure 1, the main structure of the exercise device is connected by the upper bed board 11 and the lower bed board 9 through hinges, and the lower end of the upper bed board and the upper end of the spring 2 pass through Screws and nuts are connected, the lower end of the spring is connected with the upper end of the swash plate 3 through screws and nuts, the rear part of the lower end of the slant plate is connected with the middle part of the upper end of the bottom plate 4 through a hinge, and the front part of the lower end of the slant plate is respectively connected with the upper ends of the two lifters 1 through screws. The lower ends of the two lifters are respectively connected with the front part of the upper end of the base plate by screws; Nut connection, the lower ends of the four bed legs are respectively connected to the upper end of the base plate through screws and nuts. the

The upper ends of the lower bed boards are respectively connected with two fixing bands 7 by screws and nuts, and the other ends of the two fixing bands are respectively connected with the upper ends of the lower bed boards by locking switches 8 . the

A hollow groove 10 is provided in the middle of the connection between the upper bed board and the lower bed board. the

The top of the upper bed board and the lower bed board are provided with a sponge pad fixedly connected with the bed board. the

When in use, adjust the two lifters of the spring sit-up exerciser to an appropriate height, so that the upper bed board is at the angle required by the exerciser. During practice, the practitioner sits the buttocks in the hollow groove, fixes the two ankle joints with national belts, pushes the feet on the baffle, and leans the back against the upper bed, and can do sit-ups repeatedly with the help of the spring force. In addition, patients who are recovering can practice under the protection and assistance of their caregivers. For example: the caregiver holds the practitioner's hand to help him do sit-ups under the elastic force of the spring. Another example: the caregiver presses the upper bed board firmly, allowing the practitioner to practice sit-ups under the increased elastic effect. the
