Description

Technical Field

[0001] The utility model belongs to the technical field of fitness equipment, in particular to a fitness board. Background Art

[0002] At present, the abdominal exercise equipment on the market is divided into large abdominal exercise equipment used in gyms according to the usage scenario. It generally includes a large frame, a handle is set at the upper end of the frame, and a sliding pad is set for the user to kneel on. The user pulls the sliding pad with his lower limbs to achieve abdominal exercise. Due to its overall complexity and large size, it is not suitable for home abdominal exercise.

[0003] Therefore, a new type of small abdominal wheel has appeared on the market. Its structure is shown in patent CN219110760U, which includes an elbow support, a support rod and two wheels arranged front and back. The user's elbow is supported on the elbow support, and his hand is on the support rod. The user pushes the wheel forward and pulls the wheel back to do abdominal exercises. Although the current two-wheeled abdominal wheel has improved overall stability compared to the previous one-wheeled abdominal wheel, the user does not always keep the body trunk aligned with the axial direction of the abdominal wheel during use, and it is easy to deviate during use. Therefore, there is still a threat of tipping over during use.

[0004] As an improvement, abdominal fitness boards have appeared in the market, such as Chinese patent CN202322534921.3, a track-type abdominal fitness device, including a base, the base is provided with a track arranged along the front-to-back direction of the base; the base is provided with a sliding member, the sliding member is slidably connected to the track; the sliding member includes an elbow support part and a hand-held part, and the hand-held part at least partially extends toward the end of the elbow support part in the forward direction. This product forms a stable abdominal fitness direction through a track-type base, and has better stability, so it has a better abdominal fitness effect, but this product also has certain shortcomings: the handlebar of this product extends forward, the user's arm is placed on the elbow support part, the hand and part of the arm are suspended in front of the elbow support part, and the hand can only grasp the handlebar. After long-term use, the palm and the unsupported arm part are uncomfortable. Summary of the invention

[0005] The utility model aims to provide a fitness board with good supporting effect and comfortable use.

[0006] The purpose of the utility model is achieved in this way:

[0007] A fitness board comprises a board body, both sides of which are provided with longitudinal slide rails; an elbow support board is slidably arranged on the longitudinal slide rails and can only move on the longitudinal slide rails; an insertion hole is arranged on the elbow support board, a handle bar can be inserted from top to bottom, and at least part of the gripping part of the handle bar is inside the elbow support board; when a user supports his arm on the elbow support board and grips the handle bar, the user's hand can abut against the elbow support board.

[0008] The longitudinal slide rail is independently provided with corresponding toggle support plates, the front ends of the two toggle support plates are provided with plug holes, and the middle part of the toggle support plates is provided with a recessed part.

[0009] The handle bar and the insertion hole are tightly matched; or, a lock buckle is arranged on the handle bar, and a slot matching with the lock buckle is arranged in the insertion hole.

[0010] The insertion hole is provided with at least one longitudinal slot, and the peripheral side of the handle bar is provided with convex ribs. The handle bar can be inserted into the insertion hole only after the convex ribs are aligned with the corresponding longitudinal slots.

[0012] At least three rollers are arranged at the lower end of the toggle support plate, and the toggle support plate moves on the plate body by relying on the rollers.

[0013] Under the action of the roller, a gap is formed between the elbow support plate and the plate body; a step portion is provided on the handle rod, and when the handle rod is inserted into the socket to the limit position, the step portion of the handle rod abuts against the upper end surface of the socket, and the lower end of the handle rod passes through the socket and does not contact the plate body.

[0014] An elastic rope is arranged at the lower end of the plate body, one end of the elastic rope is fixed to the lower end of the elbow support plate, and the other end of the elastic rope is fixed to the plate body.

[0015] Both ends of the elastic rope are provided with large head sections, and the elbow support plate and the plate body are provided with slots for clamping the large head sections, and the large head sections are put into the slots from the openings; the plate body includes an upper body and a lower cover, and the lower cover and the upper body are covered to cover the openings of the slots.

[0016] At least two rotating wheels are arranged in the plate body, and the bending position of the elastic rope is supported by the rotating wheels; the plate body comprises an upper body and a lower cover, and the elastic rope and the rotating wheels are encapsulated between the upper body and the lower cover.

[0017] Compared with the prior art, the utility model has the following outstanding and beneficial technical effects:

[0018] 1. The utility model adopts a method of inserting the handle bar into the socket of the elbow support board, so that when the user supports the arm on the elbow support board and holds the handle bar, the user's hand can abut against the elbow support board; that is, the user's arm and hand can abut against the elbow support board, the user's arm and hand support effect is good, and the use is more comfortable; the user can use the product even if he does not want to grasp the handle bar, and the user can also use it with the arm supported on the elbow support board, which gives the user more choices.

[0019] 2. The lower end spiral side wall of the socket of the utility model is provided with a limit portion at the end of the spiral side wall; after the handle bar is inserted into the bottom of the socket, the handle bar is rotated, and the protrusion can be clamped on the limit portion. The user first inserts the handle bar into the socket until the bottom is found and the handle bar is rotated to allow the protrusion to be clamped on the limit portion, thereby achieving stable installation of the handle bar, and the handle bar will not be separated from the elbow support seat. Preferably, the handle bar will not contact the plate body after installation, so the handle bar will not interfere with movement.

[0020] 3. The elastic rope of the utility model is provided with a large head section at both ends, and the elbow support plate and the plate body are provided with a slot for clamping the large head section, and the large head section is put in from the opening of the slot; the plate body includes an upper body and a lower cover, and the lower cover and the upper body cover the opening of the slot. Through this structure, the assembly difficulty of the manufacturer is greatly reduced and the assembly efficiency is improved. The worker only needs to put the large head section of the elastic rope into the corresponding slot and then seal the lower cover. BRIEF DESCRIPTION OF THE DRAWINGS
