Description

Technical Field

[0001] This utility model belongs to the field of treadmill technology, and specifically relates to an adjustable handrail mounting structure for a treadmill. Background Technology

[0002] Existing treadmill handrails on the market are usually designed to be foldable to save space during transportation and storage. The existing folding structure of treadmill handrails includes a handrail that can be rotated and connected to the treadmill frame, as well as fasteners. To unlock, the fasteners are loosened, and the treadmill handrail can be rotated. However, the drawback of this structure is that when the fasteners are loosened, the handrail is separated from the treadmill frame. After separation, the operator needs to use a lot of force to limit the handrail to prevent it from falling out of the rotation slot, so the operation is relatively troublesome. Utility Model Content

[0003] In view of the problems mentioned in the background art, the purpose of this utility model is to provide an adjustable handrail mounting structure for a treadmill to solve the problems mentioned in the background art.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0005] An adjustable handrail mounting structure for a treadmill includes a mounting housing fixedly connected to the side of the running platform frame, with a limiting seat formed inside the mounting housing. It also includes a handrail connecting base, comprising a base body, the inner end of which is placed inside the mounting housing and rotatably connected to the limiting seat. A limiting block is formed on the inner end of the base body, placed inside the mounting housing and disengaged from the limiting seat. The structure further includes a circumferential rotation limiting structure, through which, when the limiting seat and the limiting block are in contact, the base body relative to the mounting housing... The base body is fixed. When the limiting seat and the limiting block are separated, the base body can rotate circumferentially relative to the mounting housing. An elastic limiting ring is provided on the open end of the mounting housing. The outer diameter of the limiting block is larger than the inner diameter of the opening of the elastic limiting ring. When the limiting seat and the limiting block are in contact, a separation stroke section is formed between the limiting seat and the elastic limiting ring. A handrail is fixed on the base body. It also includes a fastening nut. A connecting hole is provided through the base body. A fixing hole is provided at the bottom of the limiting seat. The fastening nut passes through the inner end of the connecting hole and is fixedly connected to the fixing hole, thus fixing the base body on the limiting seat.

[0006] The separation stroke section allows sufficient separation space between the limit seat and the limit block within the mounting housing, enabling the limit seat and limit block to separate, allowing the base body to rotate and subsequently rotate and fold the handrail. The elastic limit ring effectively prevents the base body from completely detaching from the mounting housing when the limit seat and limit block separate, thus preventing the need for greater force to correct the handrail rotation. The elastic limit ring keeps the inner end of the base body rotating within the mounting housing.

[0007] Preferably, a rotating groove is formed on the limiting seat, and the inner end of the base body is inserted into the rotating groove; the circumferential rotation limiting structure includes a limiting groove formed on the periphery of the rotating groove, and a limiting protrusion is provided on the mating end face of the limiting block and the limiting seat. When the handrail is erected, the limiting protrusion is placed in the limiting groove to prevent the handrail from rotating.

[0008] When the handrail needs to be folded, the fastening nut is unlocked, the limiting protrusion disengages from the limiting groove, and the base body can rotate relative to the mounting housing.

[0009] Preferably, a limiting edge is formed on the front end face of the limiting seat, and a limiting hook is formed on the outer edge of the limiting block. When the armrest rotates, the limiting hook cooperates with the limiting edge to limit the rotation angle of the base body.

[0010] Preferably, the elastic limiting ring includes an outer ring body welded to the open end of the mounting base housing, and a plurality of spring pieces are formed on the outer ring body at intervals, and the spring pieces are arranged in an obliquely inward constricted shape.

[0011] The spring has slight elasticity and is arranged in a constricted shape with an inward angle. The base body can be inserted into it. When the limiting seat and the limiting block are separated, the outer edge of the limiting seat is blocked by the spring. The spring is arranged in an inward angle and needs to overcome a large force when it moves outward. In this way, the limiting seat can be limited to the mounting base housing.

[0012] Preferably, a receiving groove is provided on the inner end of the base body, and a spring is provided in the receiving groove. One end of the spring abuts against the top wall of the receiving groove, and the other end abuts against the bottom wall of the rotating groove; and the fastening nut passes through the spring.

[0013] In summary, the present invention has the following main advantages:

[0014] This application provides an elastic limiting ring on the mounting base housing. When folding the handrail, the elastic limiting ring blocks the limiting block, preventing the entire inner end of the base body from detaching from the mounting base housing, making it easier to rotate and fold, and more convenient to operate.

[0022] refer to Figures 1 to 6 This embodiment of an adjustable handrail mounting structure for a treadmill includes a mounting base housing 1 fixedly connected to the side of the running platform frame. A limiting seat 2 is formed inside the mounting base housing. It also includes a handrail connecting base, which includes a base body 3. The inner end of the base body is placed inside the mounting base housing and rotatably connected to the limiting seat. A limiting block 4 is formed on the inner end of the base body. The limiting block is placed inside the mounting base housing and is disengaged from the limiting seat. The structure also includes a circumferential rotation limiting structure. Through this circumferential rotation limiting structure, when the limiting seat and the limiting block are in contact, the base body relative to the mounting base... The base housing is fixed. When the limiting seat and the limiting block are separated, the base body can rotate circumferentially relative to the mounting base housing. An elastic limiting ring 5 is provided on the open end of the mounting base housing. The outer diameter of the limiting block is larger than the inner diameter of the opening of the elastic limiting ring. When the limiting seat and the limiting block are in contact, a separation stroke section 6 is formed between the limiting seat and the elastic limiting ring. A handrail 7 is fixed on the base body. It also includes a fastening nut 8, a connecting hole 9 is provided through the base body, and a fixing hole 10 is provided at the bottom of the limiting seat. The fastening nut passes through the inner end of the connecting hole and is fixedly connected to the fixing hole, thus fixing the base body on the limiting seat.

[0023] The separation stroke section allows sufficient separation space between the limit seat and the limit block within the mounting housing, enabling the limit seat and limit block to separate, allowing the base body to rotate and subsequently rotate and fold the handrail. The elastic limit ring effectively prevents the base body from completely detaching from the mounting housing when the limit seat and limit block separate, thus preventing the need for greater force to correct the handrail rotation. The elastic limit ring keeps the inner end of the base body rotating within the mounting housing.

[0024] Specifically, a rotating groove 11 is formed on the limiting seat, and the inner end of the base body is inserted into the rotating groove; the circumferential rotation limiting structure includes a limiting groove 12 formed on the periphery of the rotating groove, and a limiting protrusion 13 is provided on the mating end face of the limiting block and the limiting seat. When the handrail is erected, the limiting protrusion is placed in the limiting groove to prevent the handrail from rotating.

[0025] When the handrail needs to be folded, the fastening nut is unlocked, the limiting protrusion disengages from the limiting groove, and the base body can rotate relative to the mounting housing.

[0026] A limiting edge 14 is formed on the front end face of the limiting seat, and a limiting hook 15 is formed on the outer edge of the limiting block. When the armrest rotates, the limiting hook cooperates with the limiting edge to limit the rotation angle of the base body.

A plurality of spaced-apart spring tabs 16 are formed on the outer ring body, and these spring tabs are arranged in an inwardly constricted shape. The spring tabs are slightly elastic, and their inwardly constricted arrangement allows the base body to pass through smoothly. When the limiting seat separates from the limiting block, the outer edge of the limiting seat is blocked by the spring tabs, which are arranged in an inwardly constricted shape. Moving outward requires overcoming a significant force, thereby confining the limiting seat within the mounting base housing.

[0028] A receiving groove 17 is provided on the inner end of the base body, and a spring 18 is provided in the receiving groove. One end of the spring abuts against the top wall of the receiving groove, and the other end abuts against the bottom wall of the rotating groove; and the fastening nut passes through the spring.

[0029] The spring design allows the limiting protrusion to disengage from the limiting groove during unlocking, enabling the armrest to rotate.
