DETAILED DESCRIPTION

[0025] In order to make the technical solution of the present invention clearer, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] Example

[0027] like Figure 1 and Figure 3 As shown, the upper surface of the mounting plate 1 is provided with a plurality of through-type mounting holes 16;

[0028] The multiple mounting holes 16 provide for the mounting plate 1 to be stably mounted on the mounting plane, thereby ensuring that the entire training device remains stable and reliable under high-intensity use, effectively reducing the risk of the device loosening or falling off due to uneven force, and providing safety protection for the user.

[0029] like Figure 1 , Figure 2 and Figure 5 As shown, a physical fitness training device is provided, comprising a mounting plate 1, a fixing rod 2 is symmetrically fixedly connected to the upper surface of the mounting plate 1, a through-type extension circular hole 3 is opened on the inner upper surface of the two fixing rods 2, an extension rod 4 is arranged inside the two extension circular holes 3, a gripping rod 5 is fixedly connected to the opposite sides of the two extension rods 4, a fixing ring 15 is fixedly connected to the bottom ends of the two extension rods 4, and the outer side walls of the two fixing rings 15 are respectively slidably connected to the inside of the two fixing rods 2;

[0030] When in use, training is performed by grasping the gripping rod 5, and the overall height of the gripping rod 5 can be adjusted by adjusting the positions of the two extension rods 4 to meet the needs of people of different heights. At the same time, the two fixed rings 15 are provided and slide in cooperation with the internal of the two fixed rods 2 to make the two extension rods 4 more stable when extended, thereby increasing the stability and flexibility of the device.

[0031] like Figure 1 As shown, the outer wall of the gripping rod 5 is fixedly connected with a rubber tube 31;

[0032] The rubber tube 31 can effectively increase the gripping force between the hand and the gripping rod 5, preventing the hand from sliding, thereby preventing people from falling and getting injured.

[0033] like Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, an operating groove 6 is integrally formed on the upper surface of the mounting plate 1, an operating handle 7 is arranged inside the operating groove 6, a sliding cavity 8 is integrally formed inside the operating handle 7, a sliding plate 9 is slidably connected inside the sliding cavity 8, a connecting rod 10 is fixedly connected to the lower surface of the sliding plate 9, the bottom end of the connecting rod 10 is rotatably connected to the lower surface of the inner part of the mounting plate 1 through a rotating shaft, a pulley 11 is fixedly connected to the outer wall of the connecting rod 10 and located inside the mounting plate 1, and a pulley 2 12 is rotatably connected to the lower surface of the inner part of the mounting plate 1 and located on the left and right sides of the pulley 11 through a rotating shaft, and the pulley The outer wall of the first 11 and the outer wall of the two pulleys 12 are jointly connected with a transmission belt 13, the upper surface center of the two pulleys 12 is fixedly connected with an adjusting screw 14, the top of the two adjusting screws 14 respectively extends to the inside of the two extension rods 4, the outer wall of the two adjusting screws 14 is respectively threadedly connected with the two extension rods 4, the inner lower surface of the operating groove 6 and located below the operating handle 7 are integrally formed with a plurality of fixing holes 17, the lower surface of the operating handle 7 is fixedly connected with a plug-in protrusion 18 on the left side, and the bottom end of the plug-in protrusion 18 extends to the inside of the left fixing hole 17;

[0034] When the overall height of the gripping rod 5 needs to be adjusted, the operating handle 7 is first pulled upward to pull the plug-in protrusion 18 out of the fixing hole 17 on the left side, and then the operating handle 7 is rotated, and then the connecting rod 10 is rotated through the sliding plate 9. The rotation of the connecting rod 10 drives the pulley 11 on the outer wall to rotate, and the pulley 11 drives the pulleys 12 on the left and right sides to rotate synchronously through the transmission belt 13, so that the two adjusting screws 14 are rotated accordingly through the two pulleys 12. Since the adjusting screws 14 are threadedly connected to the extension rod 4, the two adjusting screws 14 rotate at the same time, which can control the two extension rods 4 to extend or retract synchronously. When the height adjustment of the gripping rod 5 is completed, the operating handle 7 is pressed downward to insert the plug-in protrusion 18 into the corresponding fixing hole 17, so that the operating handle 7 can be fixed, thereby reducing the wear on the two adjusting screws 14 and increasing the service life of the device, thereby realizing fast and synchronous adjustment of the gripping rod 5, saving adjustment time and improving the efficiency of physical training.

[0035] like Figure 5 As shown, guide bars 25 are fixedly connected to the left and right sides of the inner side of the extended circular hole 3, and guide vertical grooves 26 are symmetrically opened on the outer side wall of the extended rod 4, and the opposite sides of the two guide bars 25 are respectively slidably connected to the inner sides of the two guide vertical grooves 26;

[0036] When the two extension rods 4 move up and down in the extension circular hole 3, the guide bar 25 slides in the guide vertical groove 26, which plays a precise guiding role, ensuring that the extension rods 4 move stably along a predetermined straight line direction, avoiding shaking, deviation, etc., further improving the stability and reliability of the entire training device, and ensuring the safety of the user during training.

[0037] like Figure 1 , Figure 3 and Figure 4 As shown, a cover plate 19 is arranged inside the operation slot 6 and above the operation handle 7, the upper surface of the cover plate 19 is rotatably connected to the upper surface of the mounting plate 1 through a hinge, a snap-fit ​​groove 20 is integrally formed on the front surface of the cover plate 19, an extrusion chamber 21 is integrally formed inside the mounting plate 1 and in front of the operation slot 6, a piston plate 22 is slidably connected inside the extrusion chamber 21, an oblique plate 23 is fixedly connected to the rear surface of the piston plate 22, the rear side of the oblique plate 23 extends to the inside of the snap-fit ​​groove 20, a plurality of springs 24 are fixedly connected to the front surface of the piston plate 22 and the inside of the extrusion chamber 21, a pull plate 27 is arranged in front of the mounting plate 1, a control chamber 28 is integrally formed inside the mounting plate 1 and in front of the extrusion chamber 21, the control chamber 28 is communicated with the extrusion chamber 21, a piston plate 29 is slidably connected inside the control chamber 28, a pull rod 30 is fixedly connected at the front surface of the piston plate 29 and the center of the rear surface of the pull plate 27;

[0038] The cover plate 19 arranged above the operating slot 6 is rotated by a hinge with the upper surface of the mounting plate 1 to protect the operating handle 7. When the cover plate 19 is closed, the oblique plate 23 is inserted into the engaging slot 20 under the action of the spring 1 24 pushing the piston plate 1 22, fixing the cover plate 19 to prevent it from being opened at will, thereby effectively protecting the operating handle 7. To open the cover plate 19 to adjust the gripping rod 5, the pull plate 27 in front of the mounting plate 1 can be pulled to drive the piston plate 29 in the control chamber 28 to slide forward through the pull rod 30. Since the control chamber 28 is connected to the extrusion chamber 21, the movement of the piston plate 29 will squeeze the space in the extrusion chamber 21, push the piston plate 1 22 forward, and pull the oblique plate 23 out of the engaging slot 20, thereby opening the cover plate 19, thereby further improving the safety and flexibility of the device.

[0039] like Figure 7 As shown, the inner lower surface of the operation slot 6 is symmetrically provided with an ejection slot 32, and the inner lower surface of the ejection slot 32 is fixedly connected with a plurality of springs 33, and the top ends of the plurality of springs 33 are in contact with the lower surface of the cover plate 19;

[0040] When the inclined plate 23 is pulled out from the engaging groove 20 and the cover plate 19 is released from being fixed, the elastic potential energy of the plurality of springs 2 33 exerts force upward to push the cover plate 19 upward, so that the user can quickly open the cover plate 19 and the operation is more convenient.

[0041] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the present invention.
