Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Reference Figure 1 , Figure 2 and Figure 5 The utility model provides an embodiment: a built-in limiter for sports facilities, including a facility body 1, a cross bar 2 is fixedly connected to the outside of the facility body 1, two fixed blocks 3 are fixedly connected to the left and right sides of the cross bar 2, and a plurality of fixed blocks 3 are provided with limiting grooves 15 inside, and a limiting plate 16 is slidably connected inside the limiting groove 15, one side of the limiting plate 16 is rotatably connected to a connecting rod 17, and the other end of the connecting rod 17 is rotatably connected to a buckle 19, and one side of the buckle 19 is fixedly connected to a second spring 18, and the outside of the cross bar 2 is slidably connected to a limiting block 4, and both sides of the outside of the limiting block 4 are provided with slots 7, and a height adjustment component is installed inside the limiting block 4.

[0025] Specifically, the cross bar 2 is fixed by the facility body 1, and then the cross bar 2 is connected to the fixing block 3, so as to achieve the effect of limiting the rising height of the load-bearing block, and the limiting plate 16 can be driven to move by the push rod 20, so that the connecting rod 17 is rotated, and the buckle 19 is pushed by one end of the connecting rod 17, so that the buckle 19 slides inside the limiting groove 15, and at the same time, the buckle 19 compresses the spring 18 to make it produce elastic deformation, and after the limiting block 4 is inserted and placed from the bottom of the cross bar 2, the push rod 20 is released, and the spring 18 can push the buckle 19 to move under the action of elastic potential energy, and then enter the card slot 7 to complete the plug-in fit, thereby completing the fixation of the limiting block 4, and the installation is completed without the aid of tools during use, and subsequent maintenance is convenient, and at the same time, the limiting block 4 is used to limit the height of the load-bearing block through the height adjustment component installed inside, so that the lifting height is controlled within a safe range to avoid injuries to users due to excessive pulling force.

[0026] Reference Figure 3 and Figure 4 The height adjustment component includes a sliding rod 10, the outside of the sliding rod 10 is slidably connected to the inside of the limiting block 4, the outside of the sliding rod 10 is fixedly connected to a rack plate 14, the inside of the limiting block 4 is rotatably connected to a rotating rod 13, one end of the rotating rod 13 is fixedly connected to a gear 12, one end of the rotating rod 13 passing through the outer wall of the limiting block 4 is fixedly connected to a rotating handle 5, a plurality of sockets 6 are provided inside the rotating handle 5, the outer side of the gear 12 is meshedly connected to the outer side of the rack plate 14, one end of the sliding rod 10 passing through the outer wall of the bottom of the limiting block 4 is fixedly connected to a baffle 11, a rubber pad is provided on the outside of the baffle 11, a slot 9 is provided on the outside of the limiting block 4, an insert rod 8 is slidably connected to the inside of the slot 9, and the outer side of the insert rod 8 is interactively connected to the inner wall of the socket 6.

[0027] Specifically, by rotating the handle 5, the rotating rod 13 is driven to rotate, and then the gear 12 drives the rack plate 14 to move, and the rack plate 14 drives the sliding rod 10 to move, so that the height of the baffle 11 changes. At this time, the insertion rod 8 is inserted into the slot 9 through the inside of the socket 6, so as to fix the handle 5, so that the gear 12 will no longer rotate, and the height of the baffle 11 will be prevented from changing again, thereby achieving the limit of the lifting height of the weight block. At the same time, different limit heights can be adjusted according to different people to meet the usage needs of different groups of people. By arranging a rubber pad on the outside of the baffle 11, the impact force of the weight block on the baffle 11 can be reduced, which has a buffering effect and thus extends the service life of the device.

[0028] Reference Figure 5A push rod 20 is fixedly connected to the other side of the limiting plate 16, one end of the push rod 20 passes through the outer wall of the fixed block 3, the outside of the push rod 20 is slidably connected to the inside of the fixed block 3, the buckle 19 is slidably connected to the inside of the limiting groove 15, the longitudinal section of the buckle 19 is set to be square, the buckle 19 and the slot 7 are plug-in fit, and the other end of the spring 18 is fixedly connected to the inner wall of the limiting groove 15.

[0029] Specifically, the limiting plate 16 can be moved by moving the push rod 20, and then the connecting rod 17 pushes the buckle 19 to move. The longitudinal section of the buckle 19 is set to a square, so that the buckle 19 and the slot 7 are plugged in without loosening, and the fixation of the limiting block 4 is more stable. Fixing one end of the spring 18 to the inner wall of the limiting slot 15 can prevent the buckle 19 from moving with the spring 18 when it moves, thereby achieving plug-in fit and fixing the limiting block 4.

[0030] Working principle: When using this device, first push the push rod 20 to make the limiting plate 16 slide inside the limiting groove 15, thereby making the connecting rod 17 move, one end of the connecting rod 17 rotates, and the other end pushes the buckle 19 to slide inside the limiting groove 15, and at the same time the buckle 19 applies pressure to the spring 18, causing the spring 18 to deform. At this time, insert the limiting block 4 into the interior from the bottom of the cross bar 2, and then release the push rod 20. The spring 18 pushes the buckle 19 to move, thereby making the buckle 19 and the slot 7 opened on the limiting block 4 complete the plug-in fit, thereby fixing the limiting block 4, and the height of the load-bearing block can be limited and controlled within the safe use range to avoid injuries caused by excessive pulling of the user. At the same time, the use of the snap-on method facilitates the installation and disassembly of the limiting block 4, and it can be used without the aid of tools, which is convenient for replacement and maintenance. Then, by rotating the handle 5, the rotating rod 13 is driven to rotate, and then the gear 12 is rotated, and the rack plate 14 is driven by the gear 12 to move, and then the slide bar 10 moves up and down, so that the height of the baffle 11 changes. It is suitable for people with different strength ranges, and the flexibility of the use of the limiter is improved. The insertion rod 8 passes through the socket 6 on the handle 5 and is inserted into the inside of the slot 9, so as to fix the rotation of the handle 5, and avoid the impact of the weight block on the baffle 11 to cause the gear 12 to flip over, and the height of the baffle 11 changes to cause the limiting effect to fail.

[0031] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
