Description

Technical Field

[0001] The utility model relates to the technical field of arm strength training, in particular to an arm strength training device. Background Art

[0002] Physical fitness refers to the basic athletic ability of the human body manifested by athletic qualities such as strength, speed, endurance, and coordination. Police officers also need to conduct physical training regularly in their daily work. Physical training of police officers' arm strength is very important and is directly related to the police's ability to perform tasks at work.

[0003] For example, the Chinese patent "CN209437985U A arm strengthener" published on September 27, 2019, installed a protective device on the middle side of the top of the second quick-release grip to solve the problem that the arm strengthener is easy to fall off the hand and cause danger. The hand is placed on the dehumidification belt. The Dr. Sha fiber layer, COOLMAX layer and MONI-DRY layer have strong sweat absorption and moisture removal functions, which can quickly dry the sweat on the hand. Then pass the Velcro through the top of the hand, insert it into the bottom slot of the buckle, and then pass it out from the top slot to fit it, so that the hand is fixed, which can increase safety and prevent the arm strengthener from falling off the hand.

[0004] During use, the existing arm strength trainers mostly adopt an integrated design, the various components cannot be replaced, and springs of different strengths cannot be replaced according to one's own training needs. They can only be used for single-intensity arm strength training, and the use effect is not good. Utility Model Content

[0005] The present invention relates to an arm strength trainer, which solves the problem that the existing arm strength trainers mostly adopt an integrated design during use, the various components cannot be replaced, and springs of different strengths cannot be replaced according to the training needs. The trainers can only be used for single-strength arm strength training and have poor use effects.

[0006] According to a first aspect of the present disclosure, an arm strength trainer is provided, which specifically includes: a main spring; quick-release connectors are welded at both ends of the main spring, and a quick-release handle is connected to the outside of the quick-release connector; two quick-release handles are provided, and a protective rope is provided on the outside of the quick-release handle; a movable locking sleeve is provided on the outside of the quick-release grip, and two movable locking sleeves are provided, and the movable locking sleeves are connected to the quick-release connector.

[0007] Furthermore, the main springs are divided into five types according to cross-sections, and the five types of main springs are equal in length.

[0008] Furthermore, a slot is provided inside the quick-release connector, a plug is provided outside the quick-release handle, and an end of the plug provided on the quick-release handle is plugged into the slot provided on the quick-release connector.

[0009] Furthermore, two L-shaped card slots are provided on the outside of the slot, and two card blocks are provided on the outside of the plug. The card blocks provided on the plug are carded in the L-shaped card slots provided on the slot, and the quick-release handle and the quick-release connector are connected together by plug-in and card-fitting methods, making it easier to replace the main spring, so that the main spring of appropriate strength can be replaced according to one's own training needs.

[0010] Furthermore, the movable locking sleeve is slidably connected to the plug provided on the quick-release grip, two limit guide blocks are provided on the outside of the plug, and two movable holes are provided on the inside of the movable locking sleeve. The limit guide blocks provided on the plug are slidably connected to the movable holes provided on the movable locking sleeve, and the limit guide blocks and the movable holes are slidably cooperated with each other, thereby achieving a guiding effect on the movement of the movable locking sleeve.

[0011] Furthermore, two locking blocks are arranged outside the movable locking sleeve, the locking blocks and the clamping block belong to different phases, and the locking blocks arranged on the movable locking sleeve are inserted into the L-shaped clamping grooves arranged on the slot.

[0012] Furthermore, an auxiliary spring is mounted on the outside of the plug of the quick-release handle, one end of the auxiliary spring is in contact with the quick-release handle, and the other end of the auxiliary spring is in contact with the movable locking sleeve. The auxiliary spring has the effect of storing force and resetting the movable locking sleeve. When the card block moves to the inner end of the L-shaped card slot, the movable locking sleeve moves under the thrust of the auxiliary spring, so that the locking block is inserted into the L-shaped card slot, and the connecting part between the quick-release connector and the quick-release handle is fixed through the movable locking sleeve.

[0013] The utility model provides an arm strength training device, which has the following beneficial effects:

[0014] When the utility model is in use, the quick-release grip is connected to the quick-release connector by means of plug-in matching and clamping, so that the main spring can be replaced more easily, so that the main spring with appropriate strength can be replaced according to one's own training needs, thereby better satisfying one's own arm strength training needs.

[0015] In addition, through the sliding cooperation between the limit guide block and the movable hole, the movement of the movable locking sleeve is guided, and the auxiliary spring has the effect of accumulating force and resetting the movable locking sleeve. When the card block moves to the inner end of the L-shaped slot, the movable locking sleeve is moved under the thrust of the auxiliary spring, so that the locking plug is inserted into the L-shaped slot. The movable locking sleeve fixes the connecting part between the quick-release connector and the quick-release grip, thereby ensuring the safety of the arm strength trainer during use. When the main spring needs to be replaced according to one's own training needs, only the movable locking sleeve needs to be moved in the opposite direction to make the auxiliary spring in a contracted state, and the locking plug is disengaged from the L-shaped slot. Then the quick-release grip can be turned to separate the card block from the L-shaped slot. The operation is simple and quick.

[0016] Other advantages, objectives and features of the present invention will be reflected in part through the following description, and in part will be understood by those skilled in the art through research and practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS
