Abstract
Description
Technical Field
[0001] This utility model relates to the field of fitness equipment, and more specifically, to an incline chest press machine. Background Technology
[0002] The decline chest fly machine is a strength training device that allows users to use barbell plates of varying weights to train the lower pectoralis major. Existing chest fly machines cannot specifically target the lower pectoralis major, and their transmission mechanisms are overly complex, costly, and difficult to maintain. Summary of the Invention
[0003] The technical problem to be solved by this utility model is to provide an incline chest press trainer that can achieve the purpose of training the lower part of the pectoralis major muscle with a relatively simple transmission mechanism.
[0004] The technical solution adopted by this utility model to solve its technical problem is as follows: Constructing an incline chest press trainer, including a frame, a counterweight arm, a transmission mechanism, and a rotating arm. The frame includes an upright, a base, an incline bar, a backrest, and a seat. The incline bar is fixedly connected to the upright and the base. The backrest and the seat are fixed on the incline bar. The counterweight arm is rotatably mounted on the upright. The counterweight arm is provided with a bell hanger. The counterweight arm is rotatably connected to the rotating arm through the transmission mechanism. The rotating arm is located on both sides of the seat.
[0005] According to the above scheme, the transmission mechanism includes a pull rod, a sector-shaped adjusting plate, and a pin. The pull rod is provided with rod end joint bearings at both ends, which are respectively connected to the counterweight arm and the sector-shaped adjusting plate. The pin is set on the moving rotating arm and is inserted into the positioning hole of the sector-shaped adjusting plate, thereby realizing the linkage between the moving rotating arm and the sector-shaped adjusting plate.
[0006] According to the above scheme, the pin is fitted with a spring, and the pin is inserted into the positioning hole under the action of the spring force.
[0007] According to the above scheme, the fan-shaped adjustment disk is provided with multiple positioning holes for adjusting the initial opening and closing angle of the moving arm.
[0008] According to the above scheme, the counterweight arm is equipped with a bell hanger.
[0009] The inclined chest press trainer of this invention has the following beneficial effects:
[0010] 1. When using this utility model, the user sits on the backrest seat, grasps the moving arm with both hands and performs a chest clamping motion. The moving arm drives the fan-shaped adjustment plate to rotate through the pin. The fan-shaped adjustment plate is connected to the pull rod through the rod end joint bearing, which causes a change in the direction of motion, thereby driving the counterweight arm to rotate and providing a load to achieve the purpose of exercising the lower part of the pectoralis major muscle.
[0011] 2. The transmission structure of this utility model is simple and easy to maintain. The initial opening and closing angle of the moving arm can be adjusted to meet the training needs of people with different arm lengths. Attached Figure Description
[0012] The present invention will be further described below with reference to the accompanying drawings and embodiments. In the accompanying drawings:
[0013] Figure 1 This is a schematic diagram of the structure of the inclined chest press trainer of this utility model;
[0014] Figure 2 This is a top view of the inclined chest press trainer of this utility model;
[0015] Figure 3 This is a schematic diagram of the transmission mechanism. Detailed Implementation
[0016] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model will now be described in detail with reference to the accompanying drawings.
[0017] like Figure 1-3 As shown, the inclined chest press trainer of this utility model includes a frame, a counterweight arm 4, a transmission mechanism, and a rotating arm 7.
[0018] The frame includes an upright frame 1, a base frame 2, a diagonal bar 3, a backrest 11, and a seat 12. The diagonal bar 3 is fixedly connected to the upright frame 1 and the base frame 2. The backrest 11 and the seat 12 are fixed on the diagonal bar 3. The counterweight arm 4 is rotatably mounted on the upright frame 1. The counterweight arm 4 is equipped with a bell hanger. The counterweight arm 4 is rotatably connected to the moving rotating arm 7 through a transmission mechanism. The moving rotating arm 7 is located on both sides of the seat 12.
[0019] The transmission mechanism includes a pull rod 5, a sector-shaped adjusting plate 6, and a pin 8. The pull rod 5 has end joint bearings 10 at both ends, which are connected to the counterweight arm 4 and the sector-shaped adjusting plate 6 respectively. The pin 8 is set on the moving rotating arm 7 and is inserted into the positioning hole of the sector-shaped adjusting plate 6, thereby realizing the linkage between the moving rotating arm 7 and the sector-shaped adjusting plate 6.
[0020] Preferably, the pin 8 is fitted with a spring 9, and the pin 8 is inserted into the positioning hole under the action of the spring 9.
[0021] Preferably, the fan-shaped adjustment disk 6 assembly has multiple positioning holes for adjusting the initial opening and closing angle of the moving arm 7. In this embodiment, three positioning holes are provided, arranged in an arc shape.
[0022] Preferably, the counterweight arm 4 is equipped with a barbell plate hanging rod, which can hang barbell plates of different weights as needed.
[0023] When using this invention, the user sits on the seat 12 and leans against the backrest 11, grasps the moving arm 7 with both hands and performs a chest-clamping motion. The moving arm 7 drives the fan-shaped adjustment plate 6 to rotate through the pin 8. The fan-shaped adjustment plate 6 is connected to the pull rod 5 through the rod end joint bearing 10, which causes a change in the direction of movement, thereby driving the counterweight arm 4 to rotate, and at the same time providing a load to achieve the purpose of exercising the lower part of the pectoralis major muscle.
[0024] The embodiments of the present invention have been described above with reference to the accompanying drawings. However, the present invention is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of the present invention without departing from the spirit and scope of the claims. All of these forms are within the protection scope of the present invention.
