[0002] A stretching device is a tool used to stretch and relax tendons, designed to help relieve muscle tension, improve body flexibility and promote blood circulation. It prevents and treats a variety of health problems by actively stretching the tendons throughout the body and adjusting the spine to a normal biomechanical state.

[0003] Common stretching devices include stretching benches, stretching boards, and stretching machines. When using a stretching board, the base plate is placed on the ground near the wall, and then the pedal is rotated to an appropriate angle. The pedal is supported and fixed by inserting a support plate into the groove of the base plate. Then, the person stands on the pedal to complete the stretching exercise.

[0004] However, when people perform bending and stretching exercises, they exert a certain forward pressure on the inclined plane, causing the inclined plane to push the base plate backward while under force, resulting in people losing their balance and falling and getting injured. Utility Model Content

[0005] The technical problem this invention aims to solve is that when people perform bending and stretching exercises, they exert a certain forward pressure on the inclined plate, causing the inclined plate to push the base plate backward while under force, resulting in the person being unstable and falling and getting injured.

[0006] The technical solution adopted by this utility model to solve its technical problem is: a sports stretching device, comprising: a base plate, which is placed on the ground to provide support for the whole; an inclined plate, which is rotatably mounted on the base plate via a shaft; a support plate, which is rotatably mounted on the inclined plate via a shaft, wherein the support plate is inserted into a groove in the base plate to support and fix the inclined plate; and a stabilizing device, which is detachably mounted on the base plate, wherein the stabilizing device fixes the base plate to the ground and prevents the base plate from sliding under force.

[0007] Preferably, the stabilizing device includes: a rectangular cover, which is detachably mounted on the base plate via a fixing component; and a suction cup, which is slidably mounted inside the rectangular cover via a round rod, wherein the suction cup limits the position of the base plate by adhering to the smooth ground.

[0008] The effect achieved by the above components is as follows: By setting up a stabilizing device, the rectangular cover is first assembled onto the base plate through a fixing component. When the base plate is placed on a smooth surface, the round rod connected to the suction cup is manually pressed, causing the round rod to move the suction cup up and down along the inside of the rectangular cover. When the suction cup moves to a position where it is tightly attached to the smooth surface, the suction cup uses its attachment to the smooth surface to assist in limiting the position of the base plate, reducing the risk of the base plate slipping under force during use, which could cause people to lose their balance and fall and get injured, thus improving the stability of the base plate.

[0009] Preferably, the stabilizing device further includes an anti-slip plate, which is fixed to the rectangular cover, wherein one side of the anti-slip plate is provided with multiple rubber protrusions.

[0010] The effect achieved by the above components is that by setting the anti-slip plate, the anti-slip plate can increase the contact area between the rectangular cover and the ground, and at the same time increase the friction between the rectangular cover and the ground, further improving the frictional resistance between the base plate and the ground.

[0011] Preferably, the stabilizing device further includes: a spring rod, which is slidably installed in the hole of the rectangular cover, wherein the other end of the spring rod is fixed to the rectangular cover, and one end of the spring rod is fixedly connected to a pressure plate; and an insert rod, wherein the insert rod is uniformly fixed to the pressure plate, and wherein the pressure plate moves along the inside of the rectangular cover and inserts the insert rod into the ground to limit its position on the bottom plate by squeezing it.

[0012] The effect achieved by the above components is as follows: by setting the insertion rod, the pressure plate moves up and down along the inside of the rectangular cover by manually pressing the spring rod, so that the pressure plate moves the insertion rod closer to the ground, so that the insertion rod is inserted into the soil and limits the rectangular cover, thereby achieving auxiliary limiting of the base plate when used outdoors and improving the stability of the base plate when personnel use it outdoors.

[0013] Preferably, the surface of the insertion rod is provided with a plurality of barbs, which are evenly arranged, wherein the barb feet face the pressure plate.

[0014] The effect achieved by the above-mentioned components is that by setting barbs, the resistance after the insertion rod is inserted into the soil surface can be increased, thereby further improving the limiting effect of the insertion rod.

[0015] Preferably, the stabilizing device further includes an intercepting rod, wherein the intercepting rod is slidably mounted on the rectangular cover, and wherein the intercepting rod limits the pressure plate by inserting into the interior of the rectangular cover.

[0016] The effect achieved by the above components is as follows: by setting up the intercepting rod, after the insertion rod is inserted into the soil surface, the intercepting rod can be manually inserted into the rectangular cover to limit the pressure plate and the insertion rod, reducing the possibility of the insertion rod resetting under the pull of the spring rod.

[0017] Preferably, the fixing component includes: a round hole rod fixedly connected to the base plate; a screw rod, the surface of which is slidably connected to the inner wall of the rectangular cover, wherein the inner wall of the round hole rod is larger than the screw rod, and a threaded hole ring is threadedly connected to the surface of the screw rod, wherein the surface of the threaded hole ring is larger than the round hole rod; and a hole block fixedly connected to the screw rod, wherein the hole block limits the screw rod by fitting it inside a cylinder inside the rectangular cover, and wherein the screw rod is fixed by compression after being inserted into the rectangular cover and the round hole rod.

[0018] The effect achieved by the above components is as follows: by setting the fixing components, the screw is first manually inserted into the hole of the rectangular cover, so that the hole block fits on the cylinder to limit the screw. At this time, the rectangular cover is manually moved to drive the screw to the position of inserting into the round hole rod. At the same time, the screw hole ring is manually rotated, so that the screw hole ring moves up and down along the surface of the screw, so that the screw hole ring moves to the position of pressing the surface of the round hole rod to press and fix the screw and the rectangular cover, thereby achieving the assembly and fixation between the stabilizing device and the base plate. At the same time, the stabilizing device can be disassembled when storing the base plate, improving the flexibility of use and the convenience of maintenance of the stabilizing device.

[0019] Preferably, the fixing component further includes: a screw ring, which is fixed to the screw hole ring, wherein the screw block is sleeved on the screw rod, and the surface of the screw block is provided with multiple protrusions.

[0020] The effect achieved by the above components is that by setting the screw ring, the contact area and friction between the hand and the screw ring can be increased, reducing the chance of slipping when manually turning the screw ring.

[0021] The beneficial effects of this utility model are:

[0022] By setting up stabilizing devices, the base plate can be fixed to a smooth or soil surface, intercepting and limiting the base plate, while increasing the friction between the base plate and the ground, reducing the risk of slippage during use, which could cause people to lose their balance and fall and get injured, thus improving the stability of the base plate.
