[0027] The technical scheme in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model, and obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the scope of protection of the utility model.

[0028] Referring to Figures 1-4 , the utility model provides an embodiment: a kind of sports equipment for arm strength training, including;

[0029] Two support frames 1, adjusting block 3, the outer wall of two support frames 1 with ground parallel is slidably connected with multiple adjusting blocks 3, and multiple crawling poles are provided between the two support frames 1, the two ends of the crawling pole are respectively fixedly connected with the adjacent side of the adjusting block 3 of two support frames 1 exterior sliding, adjusting block 3 can connect and support the crawling pole between two support frames 1, and simultaneously through the crawling pole, the two adjusting blocks 3 corresponding to the outer wall of two support frames 1 can be connected, so that the two adjusting blocks 3 corresponding to the relative movement under the action of crawling pole.

[0030] Multiple climbing poles are parallel to each other to facilitate students' lateral movement and gripping of the poles, thereby improving the smoothness and stability of their movement.

[0031] The push plate 4 is slidably installed on the side of one of the support frames 1 away from the climbing rod. The side of the push plate 4 near the support frame 1 is provided with a sliding groove 6 and multiple sliding grooves 5. The support frame 1 near the push plate 4 is provided with a fixing member for fixing the push plate 4. The push plate 4 can move up and down under the action of the fixing member to adjust the height of the push plate 4 off the ground and to position the moved push plate 4 through the fixing member.

[0032] The first sliding groove 6 is located in the middle of the push plate 4. Multiple second sliding grooves 5 are symmetrically distributed on both sides of the first sliding groove 6, with the first sliding groove 6 as the center. Sliding rods 2 are slidably installed in the inner cavities of both the first sliding groove 6 and the multiple second sliding grooves 5. One end of each sliding rod 2 is fixedly connected to one side of a multiple adjusting block 3. The second sliding grooves 5 are inclined away from the first sliding groove 6, and the inclination angle of the second sliding grooves 5 increases sequentially from the first sliding groove 6. When the push plate 4 moves up and down, the sliding rods 2 inside the first sliding groove 6 remain stationary. It does not move with the push plate 4 moving up and down. When the push plate 4 moves up, the sliding rod 2 inside the sliding groove 2 5 moves synchronously towards the sliding groove 1 6, so that the adjusting blocks 3 located on both sides of the sliding groove 1 6 gather towards the middle of the support frame 1 and always maintain the same distance. This helps to reduce the distance between two adjacent climbing rods, which is beneficial for students with smaller arm spans to use the climbing frame to train their arm strength. It also prevents students with shorter arm spans from falling when training their arm strength due to the large distance between the climbing rods, thus improving the practicality of the climbing frame in use.

[0033] Furthermore, when the push plate 4 is lowered, the sliding rod 2 inside the sliding groove 5 moves in the opposite direction, thereby increasing the distance between two adjacent climbing rods, so that students with longer arm spans can perform arm strength training.

[0034] Both support frames 1 are designed with an L-shaped structure, and the bottom of the two support frames 1 are connected to the ground by bolts to facilitate the connection between the support frame 1 and the ground. This also increases the distance between the climbing pole and the ground, allowing students to move horizontally without their feet touching the ground.

[0035] The slide rod 2 is configured as a T-shaped structure, and the small end of the slide rod 2 is fixedly connected to one side of the adjustment block 3. The large end of the slide rod 2 passes through the first sliding groove 6 and the second sliding groove 5 and extends to the other side of the push plate 4. This allows the slide rod 2 to move left and right under the action of the second sliding groove 5 while preventing the end of the slide rod 2 away from the adjustment block 3 from coming off the inside of the second sliding groove 5.

[0036] One side of the plurality of adjusting blocks 3 is provided with a through hole communicated with the other side, and the plurality of adjusting blocks 3 are slidably sleeved outside the support frame 1 through the through hole, a plurality of U-shaped frames 9 are fixedly installed on the inner wall of the through hole in a ring-shaped distribution, the inner wall of the U-shaped frame 9 is rotatably installed with a guide wheel 10 abutting the outer wall of the support frame 1 through a rotating shaft, when the adjusting block 3 moves linearly along the outer wall of the support frame 1, the guide wheel 10 rotates along the axis direction of itself, thereby reducing the friction between the inner wall of the through hole and the outer wall of the support frame 1, and improving the smoothness when the adjusting block 3 moves left and right.

[0037] The fixing member comprises a connecting plate 7 and a sleeve 8, wherein the outer wall of the support frame 1 close to the push plate 4 is symmetrically slidably sleeved with the sleeve 8, the outer wall of the two sleeves 8 is fixedly installed with the connecting plate 7 connected with the outer wall of the push plate 4, and the sleeve 8 can limit the movement track of the push plate 4 under the action of the connecting plate 7, and prevent the push plate 4 from deviating when moving.

[0038] The outer wall of the two sleeves 8 is provided with a through hole, the inner cavity of the through hole is movably installed with a latch 11, and the outer wall of the support frame 1 is provided with a plurality of plug-in holes 12 matched with the latch 11, when the sleeve 8 moves to the middle of the opening end of the through hole and the middle of the opening end of one of the plug-in holes 12 is at the same horizontal line, the small end of the latch 11 is inserted into the inside of the plug-in hole 12 through the through hole, which is beneficial to the fixation of the sleeve 8, prevents the sleeve 8 from moving again, and improves the stability of the crawling rod.

[0039] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and not for limiting the present application, although the present application has been described in detail with reference to the foregoing embodiments, for those skilled in the art, it still can modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part of the technical features, any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application, shall be included in the protection scope of the present application.
