In the current structure, the height of the turntable assembly 2 can be adjusted, and it is stabilized at the required height by the fixed pin assembly. However, since the turntable assembly 2 has a certain dead weight and is relatively heavy, when adjusting the height, the user must first overcome the gravity of the turntable assembly 2, and then stabilize it by the fixed pin assembly. There are certain safety risks and it is not easy to operate. In addition, the fixed pin assembly is generally located on the side, which is not easy to observe and operate. Utility Model Content

[0003] The utility model provides a safety locking pin mechanism for a lateral raise and bird-clip chest training device, which can solve the problems pointed out in the background technology.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solution: it includes a main frame, a turntable assembly and a fixing pin assembly; the turntable assembly is slidably connected to the main frame, reciprocatedly adjusted along its height direction, and the turntable assembly is fixed at a desired height by the fixing pin assembly, and the lower end of the turntable assembly is connected to an elastic member, and the elastic member is used to overcome the turntable assembly and drive it to move upward.

[0005] Preferably, the elastic member is a gas spring.

[0006] Preferably, both sides of the turntable assembly are supported by the gas springs.

[0007] Preferably, the fixing pin assembly comprises an elastic latch and a hand brake handle, the elastic latch and the hand brake handle are both fixed to a fixing plate of the turntable assembly, and the elastic latch and the hand brake handle are connected via a pull wire.

[0008] Preferably, the elastic latch is fixed at the upper rear end of the fixing plate through a latch fixing plate, and the handbrake handle is fixed at the lower front end of the fixing plate.

[0009] Beneficial effects: The utility model provides a safety lock pin mechanism for lateral raise and bird-clip chest training. First, an elastic member is arranged to overcome the gravity of the turntable assembly, which is convenient for operation and improves safety.

[0010] In addition, the handbrake handle is set at the easiest operating position, and the elastic latch is set at an easy-to-observe position to facilitate adjustment of the operation and improve user experience. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] A specific implementation mode of the present utility model is described in detail below in conjunction with the accompanying drawings, but it should be understood that the protection scope of the present utility model is not limited by the specific implementation mode.

[0017] Example 1: Figure 1-3 The safety locking pin mechanism of a lateral raise and pec fly training device comprises a main frame 1, a turntable assembly 2 and a fixed pin assembly; the turntable assembly 2 is slidably connected to the main frame 1 through the cooperation of a sliding sleeve 51 and a sliding column 52, and can be reciprocated and adjusted along its height direction, the sliding column 52 is connected to both sides of the main frame 1, the sliding sleeves 51 are connected to both sides of the turntable assembly 2, and the turntable assembly 2 is fixed at a desired height through the fixed pin assembly, and the lower end of the turntable assembly 2 is connected to an elastic member 3, and the elastic member 3 is used to overcome the turntable assembly 2 and drive it to move upward.

[0018] Specifically, the elastic member 3 is a gas spring, and both sides of the turntable assembly 2 are supported by the gas spring. The lower end of the gas spring is connected to the bottom frame of the main frame 1, and the upper end is connected to the sliding sleeve 51.

[0019] The fixing pin assembly includes an elastic latch 41 and a handbrake handle 42. The handbrake handle 42 is the structure of the bicycle handbrake. The elastic latch 41 and the handbrake handle 42 are both fixed on the fixing plate 21 of the turntable assembly 2. The elastic latch 41 and the handbrake handle 42 are connected by a pull wire. Specifically, the elastic latch 41 is fixed to the upper end of the rear of the fixing plate 21 through the latch fixing plate, and the elastic latch 41 is set in a position that is easy to observe; the handbrake handle 42 is fixed at the lower end of the front of the fixing plate 21, and the handbrake handle 42 is set in the easiest position to operate. The elastic latch 41 cooperates with several sockets on the main frame 1. During operation, it is only necessary to hold the handbrake handle 42 with one hand to pull out the elastic latch 41, and pull down the handbrake handle 42 with one hand to overcome the force of the elastic member 3 to achieve height reduction, and the other hand can assist in this process; when the height needs to be increased, it is only necessary to hold the handbrake handle 42 with one hand to pull out the elastic latch 41, and the height can be increased under the action of the elastic member 3.

[0020] The above disclosures are only several specific embodiments of the present invention. However, the embodiments of the present invention are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
