Description

Technical Field

[0001] This technical solution belongs to the field of fitness equipment technology, specifically a multi-functional training stool. Background Technology

[0002] Currently, most training benches on the market have a relatively simple structure, typically consisting of a fixed base, seat, and backrest. During use, the backrest angle is usually adjusted using a simple pin-type or limit-hole structure, offering limited precision and a small adjustment range. This makes it unsuitable for meeting the diverse angle requirements of different training movements. Furthermore, the bases of most existing training benches are fixed connections, lacking a buffer structure between the seat and base when users perform forceful movements such as presses and crunches. This results in strong impacts when the user exerts force or returns to the starting position, affecting the training experience and potentially causing structural loosening or user discomfort.

[0003] Therefore, there is still room for improvement in terms of angle adjustment range, structural stability, and user comfort of existing training benches.

[0004] In summary, how to provide a multifunctional training stool with a reasonable structure, flexible adjustment, cushioning function, and improved training comfort and effectiveness has become a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] In order to solve the above-mentioned technical problems, the present invention discloses the following technical solution; A multi-functional training bench, comprising: Base: The training stool body is connected to the base; Training stool body: The training stool body includes a connecting tube for cooperating with the base. A seat is fixedly connected to the top of the connecting tube, and a backrest is hinged to the back of the seat. An adjustment plate is fixedly connected to the backrest. The connecting tube has a fixing hole for positioning. The adjustment plate has several connecting holes spaced along an arc trajectory, so that when the seat is rotated, the connecting holes can sequentially coincide with the fixing holes, thereby locking the adjustment plate to the connecting tube at different angle positions through a fixing device, realizing the adjustable and fixed angle of the backrest.

[0006] Furthermore, the adjusting plate is an arc-shaped adjusting plate.

[0007] Furthermore, the fixing device is a bolt or a locating pin.

[0008] Furthermore, the base includes a front positioning rod and a rear positioning rod, and a connecting part is provided between the front positioning rod and the rear positioning rod, and the connecting tube is connected to the connecting part; Furthermore, a receiving space is provided in the middle of the connecting part, and an adjusting rod is provided in the receiving space. One end of the adjusting rod is hinged to the middle of the front positioning rod, and an angle adjusting rod is hinged to the middle of the rear positioning rod. The angle adjusting rod has several adjusting holes, and the other end of the adjusting rod is provided with a U-shaped connector. The U-shaped connector has a through hole, so that the tail of the adjusting rod can be fixed to the adjusting hole of the angle adjusting rod by a fixing device, so that the angle of the training stool body can be adjusted by changing the fixed adjusting hole.

[0009] Furthermore, the adjusting rod is provided with a U-shaped groove, and the two sides of the opening of the U-shaped groove extend inward to form limiting baffles. A slit is formed between the two limiting baffles along the length of the groove. The width of the slit is less than the width of the U-shaped groove inside and greater than the width of the connecting tube. A stop block is provided at the bottom of the connecting tube, and the connecting tube slides back and forth on the adjusting rod through the stop block. Buffer devices are provided at both ends of the U-shaped groove. The buffer devices are located on the front and rear sides of the stop block, and their ends abut against the stop block and the end of the U-shaped groove, respectively. The elastic action of the buffer devices positions the stop block in the middle of the U-shaped groove, so that the seat can move a small distance according to the direction of the user's force during use, thereby further improving the comfort and exercise effect of the exerciser.

[0010] Furthermore, the buffer device is a buffer spring. When the buffer device adopts the form of a buffer spring, compression springs with different stiffness coefficients and stroke lengths can be selected according to the expected load-bearing capacity and rebound requirements of the training bench. For example, a helical compression spring made of carbon spring steel can be used. Such springs are available in a full range of specifications in the current market and can meet different load and rebound requirements.

[0011] As another option, the buffer device is a gas spring. When the buffer device is in the form of a gas spring, a standard gas spring with buffer return function can be selected as needed. Its structure, thrust level and connection end type are all ready-made products and can be conventionally selected according to design requirements.

[0012] Furthermore, the two ends of the U-shaped groove are respectively fixedly connected to one end of the buffer device.

[0013] Compared with the prior art, the present invention has the following outstanding advantages: 1 / This application sets a fixing hole on the connecting pipe, arranges multiple connecting holes along an arc trajectory on the adjusting plate, and uses bolts or positioning pins for locking, so that the angle of the backrest can be precisely adjusted in multiple positions to meet the needs of different training postures.

[0014] 2 / This application provides several adjustment holes on the angle adjustment rod, and the tail of the adjustment rod is fixed by a U-shaped connector and a through hole, so that the tilt angle adjustment process of the training stool is stable, safe and has high repeatability.

[0015] 3 / This application incorporates a U-shaped groove structure on the adjusting rod, with limiting baffles on both sides forming a slit. A stop block is located at the bottom of the connecting pipe, sliding within the U-shaped groove. Both ends are equipped with buffer devices (buffer springs or gas springs). When the user exerts force during training, the seat can undergo slight displacement according to the direction of force, and the impact is absorbed by the buffer devices, achieving a flexible buffering effect and significantly improving training comfort.
