Description

Technical Field

[0001] The utility model relates to the field of fitness equipment, in particular to a safety protection device for fitness equipment. Background Art

[0002] With the improvement of science and technology and the development of society, more and more fitness equipment has poured into our lives, bringing convenience to people's fitness, especially some elderly people, who no longer need to go to the gym for training. However, with the popularity of fitness equipment at this stage, some fitness equipment is installed in the community without fences to prevent children from using it. Therefore, some fitness equipment has great safety hazards for children. For example, the waist spinner has a high risk index. The waist spinner itself is not dangerous, but children like to play in an alternative way, that is, they stand on the turntable and spin in circles without holding the handles. If they are not careful, they may be thrown out, and at the very least they may fall to the ground, or even hit their heads on the pillars of the waist spinner. In addition, intense use of this equipment may cause children to strain their lumbar muscles. Therefore, the use of the waist spinner requires certain protection. To this end, we propose a safety protection device for fitness equipment. Utility Model Content

[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods. Example

[0020] like Figure 1-5 As shown, a safety protection device for fitness equipment comprises a mounting base 1, a handrail 2 is fixedly mounted on the upper surface of the mounting base 1, a curved tube 3 is fixedly connected to the curved surface of the handrail 2 near the lower end at four equal positions, a waist-turning structure 4 is fixedly mounted on the other end of the curved tube 3, a protective locking structure 5 is fixedly mounted inside the waist-turning structure 4, a second limiting groove 10 is opened at the four equal positions of the upper end surface of the mounting base 1, a rack 6 is movably mounted inside the second limiting groove 10, a gripping plate 8 is fixedly mounted on the curved surface of the handrail 2 near the upper end surface, a first limiting groove 9 is opened at the four equal positions of the gripping plate 8, and an unlocking fixing structure 7 is movably mounted in the first limiting groove 9;

[0021] The waist rotating structure 4 includes a base 401, a plane bearing 402, an upper rotating disk 403, a locking hole 404 and a guide wheel 405. The plane bearing 402 is fixedly installed on the upper surface of the base 401, the upper rotating disk 403 is fixedly installed on the upper surface of the plane bearing 402, and the locking hole 404 is opened on the lower surface of the upper rotating disk 403. The locking hole 404 is arranged very tightly. Even if the locking pin 502 just fails to fit into the locking hole 404, it only needs a small rotation to automatically fit into the nearest locking hole 404 under the elastic force of the return spring 504, which will not affect the normal protection function of the device. The inner surface of the base 401 is fixedly installed with a guide wheel 405 at the port connected to the curved pipe 3. The guide wheel 405 plays a guiding and labor-saving role. It can be set at the turning point of the wire rope 505 as needed to play a more labor-saving role when pulling the wire rope 505; there are multiple locking holes 404, and they are arranged in a ring array The protective locking structure 5 includes a locking sleeve 501, a locking pin 502, a limiting ring 503, a return spring 504 and a steel wire rope 505. The locking sleeve 501 is movably installed with a locking pin 502, the surface of the locking pin 502 is fixedly installed with a limiting ring 503, the surface of the limiting ring 503 is sleeved with a return spring 504, and the lower end of the locking pin 502 is fixedly connected with a steel wire rope 505; the upper end of the rack 6 is fixed A lifting ring 601 is installed, and the wire rope 505 passes through the curved tube 3 and the support rod 2 and is fixedly connected to the lower end of the rack 6; the unlocking and fixing structure 7 includes a fixing pin 701, a retaining ring 702, a paddle 703 and a return spring 704, the retaining ring 702 is fixedly installed on the surface of the fixing pin 701, the paddle 703 is fixedly installed on the surface of the retaining ring 702, the return spring 704 is sleeved on the surface of the fixing pin 701, and the second limiting groove 10 is connected to the first limiting groove 9.

[0022] It should be noted that the utility model is a safety protection device for fitness equipment. When an adult uses it, he can directly stand on the upper turntable 403, and then lift the rack 6 upward by pulling the lifting ring 601. At this time, the teeth on the rack 6 will squeeze the fixing pin 701 into the first limiting groove 9 until the rack 6 can no longer be lifted upward, and the fixing pin 701 is inserted into the gap between the teeth at the corresponding position on the rack 6, thereby fixing the rack 6. At this time, the lifting of the rack 6 will pull the wire rope 505 to make the locking pin 502 disengage from the locking hole 404, so that the upper turntable 403 can pass through the plane bearing 402. It rotates on the base 401, so the user can start fitness exercises. When the exercise is finished, the user needs to push the paddle 703 to its own position to make the fixing pin 701 disengage from the tooth gap on the rack 6. At this time, under the rebound action of the reset spring 504, the locking pin 502 will be stuck in the locking hole 404 at the corresponding position, and at the same time, the rack 6 is pulled down to the second limit groove 10 through the wire rope 505, thereby locking the upper turntable 403. In this way, children cannot reach the lifting ring 601 due to their short stature, so there will be no safety accidents caused by children getting injured while playing due to the upper turntable 403.

[0023] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
