[0027] With the improvement of people's living standards and the increase of life pressure, more and more people will choose to relieve the pressure of life and strengthen their bodies through fitness. Among the many exercise equipment, arm strength exercise equipment can exercise the arms, chest muscles and back at the same time, and can relieve the fatigue of the arms and back. Therefore, arm strength exercise equipment is loved by more and more people.

[0028] In the related art, people who exercise will adjust the number of weight plates according to their own situation. The adjustment method is to insert pins into different weight plates, that is, the weight will be different during exercise. However, there is no fixation between the existing pins and the weight plates, and the spring rope on the pin can be easily tripped by people passing by on the ground, or accidentally rubbed off, thereby causing harm to the person who is exercising.

[0029] In order to solve the problems in the related art to a certain extent, the embodiment of the present application provides a lifting and pulling type arm strength training device. When the latch 14 needs to be inserted into the weight plate on the training weight mechanism 12, the push rod 23 is inserted into the inside of the latch 14, and the spring 24 is squeezed and compressed, and the connecting rods 25 on both sides are driven to rotate at the same time, and the block 22 is pulled back to the inside of the latch 14 until the latch 14 is fully inserted into the inside of the weight plate. Then the pull rod 23 can be released, and the spring 24 rebounds and pushes the pull rod 23 to move and drive the connecting rod 25 to rotate, so that the block 22 protrudes out of the slot 21 to fix the latch 14. Then the user holds the training pulling mechanism 13, which will drive the weight plate to move up and down, and the arm bears the range of motion of pulling down and lifting up, so as to exercise the arm.

[0030] The present application is described below with reference to the accompanying drawings and specific embodiments:

[0031] Combination Figure 1-Figure 3 The embodiment of the present application provides a lifting and pulling type arm strength training device, including: a training fixed base 11, on which a training weight mechanism 12 is arranged; a training pulling mechanism 13 is arranged on the training fixed base 11; a latch 14 is plugged and arranged on the training weight mechanism 12; a telescopic component 2 is arranged inside the latch 14, and the telescopic component 2 includes: a slot 21 symmetrically opened on the outer wall of the latch 14; a block 22 is arranged on the inner side of the slot 21, and one end is rotatably connected to the inner wall of the slot 21; one end of a pull rod 23 is inserted into the interior of the latch 14; a spring 24 is arranged at one end of the pull rod 23 and connected to the inner wall of the latch 14; a connecting rod 25 is symmetrically hinged on the outer wall of the pull rod 23, and the other end is hinged to the block 22.

[0032] Specifically, the exercise weight mechanism 12 and the exercise pulling mechanism 13 are fixed to the exercise fixed base 11 by bolts, and the two ends of the spring 24 are connected to the inner wall of the pull rod 23 and the pin 14 by means of a clamping ring. The connection method of the clamping ring is an existing well-known technology and will not be described in detail.

[0033] During use, when the pin 14 needs to be inserted into the weight block on the exercise weight mechanism 12, first push the pull rod 23 to insert it into the inside of the pin 14, and at the same time squeeze the spring 24 to compress, and at the same time drive the connecting rods 25 on both sides to rotate, pull the block 22 back to the inside of the pin 14, until the pin 14 is completely inserted into the inside of the weight plate, then release the pull rod 23, and the spring 24 rebounds to push the pull rod 23 to move and drive the connecting rod 25 to rotate, so that the block 22 protrudes from the slot 21, thereby fixing the pin 14.

[0034] In some embodiments, the telescopic assembly 2 further includes: a push block 26 disposed at one end of the pull rod 23 .

[0035] Specifically, the push block 26 is connected to the pull rod 23 by threaded rotation.

[0037] In some embodiments, the surface of the push block 26 is wrapped with a layer of sponge cover.

[0038] When in use, the provision of the sponge cover makes the surface of the push block 26 softer, and provides a better feel when gripping.

[0039] In some embodiments, the telescopic assembly 2 further includes: a cone 27 disposed at one end of the latch pin 14 .

[0040] Specifically, the vertebral body 27 is fixedly connected to one end of the latch pin 14 by welding;

[0041] When in use, one end of the vertebral body 27 is smaller, which makes it easier to insert into the hole on the weight block, thereby making it more convenient to use.

[0042] In some embodiments, the telescopic assembly 2 further includes: a slide groove 28 opened on the outer wall of the pull rod 23; a fixing rod 29 is arranged on the inner side of the slide groove 28, and both ends are fixedly connected to the inner wall of the latch 14.

[0043] Specifically, both ends of the fixing rod 29 are fixedly connected to the inner side wall of the latch 14 by welding.

[0044] When in use, the arrangement of the slide groove 28 and the fixing rod 29 can restrict the pull rod 23 from rotating.

[0045] In some embodiments, the diameter of the fixing rod 29 is the same as the inner width and length of the sliding groove 28 .

[0046] When in use, the diameter of the fixing rod 29 is the same as the inner width and length of the sliding groove 28, so that the pull rod 23 is not easy to shake when moving.

[0047] In some embodiments, the protruding surface of the block 22 is designed as an inclined surface.

[0048] When in use, the inclined surface of the block 22 allows the block 22 to be directly inserted into the hole on the weight plate without pushing the pull rod 23 during insertion. The inclined setting allows the block 22 to be squeezed back into the interior of the latch 14 when in contact with the block 22.
