Description

TECHNICAL FIELD

[0001] The present invention relates to the technical field of fitness equipment, specifically a steel plate counterweight dumbbell and its production process and method.BACKGROUND OF THE INVENTION

[0002] Dumbbells are a simple equipment used to enhance muscle strength training. Its main material is cast iron, and some are coated with a layer of rubber. Its purpose is for muscle strength training and muscle compound movement training. Patients with low muscle strength due to paralysis, pain, and long-term inactivity can use the weight of dumbbells to actively exercise resistance and train muscle strength by holding dumbbells. Dumbbells can train a single muscle; If weight is increased, coordination of multiple muscles is required, and it can also be used as a muscle composite exercise training.

[0003] Scientifically using dumbbells can indeed achieve good exercise results. According to some sources, Schwarzenegger's muscular build back then was mainly achieved through dumbbell exercises. But there are indeed many people who, after exercising with dumbbells, neither gain strength nor become fit, often feeling discouraged and even becoming a substitute for hammers. In fact, dumbbell fitness has a lot of knowledge. If not implemented, the exercise effect is often greatly disappointed.

[0004] Most of the dumbbells used in the market are made into dumbbell rings by pouring, pouring, and gluing, which has high product costs, complex processes, and serious environmental pollution. Therefore, we propose a steel plate counterweight dumbbell and its production process and method.SUMMARY OF THE INVENTION

[0005] In response to the shortcomings of existing technology, the present invention provides a steel plate counterweight dumbbell and its production process and method, which makes the production process of the steel plate counterweight dumbbell simpler and easier to operate. It not only reduces the production cost of dumbbells, but also reduces environmental pollution during the production process. It solves the problems of high product cost, complex process, and serious environmental pollution caused by the fact that most dumbbells used in the market are made by pouring, pouring, and encapsulating.

[0006] In order to achieve the goal of making the production process of the steel plate counterweight dumbbell simpler and easier to operate, not only reducing the production cost of dumbbells, but also reducing environmental pollution during the production of dumbbells, the present invention provides the following technical solution: a steel plate counterweight dumbbell, comprising a handle, a handheld sleeve, a dumbbell bell ring, a locking piece, and a dumbbell placement seat, wherein the handheld sleeve is fixedly installed in the middle of the side wall of the handle, and two dumbbell rings are respectively installed at both ends of the side wall of the handle. The dumbbell ring is composed of several iron plates combined by screws, and the signboard is cut and formed at both ends of the dumbbell ring.

[0007] Preferably, the dumbbell body is an integrated structure consisting of the handle, handheld sleeve, dumbbell bell ring, and locking component.

[0008] Preferably, both ends of the side wall of the handle are provided with external thread grooves, and the inner side of the locking component is provided with internal thread grooves, which are matched with the external thread grooves.

[0009] Preferably, the side wall of the handheld cover is designed with a rolled anti slip mesh surface.

[0010] Preferably, the dumbbell body is placed at the top of the dumbbell placement seat through a dumbbell bell bell clip.

[0011] Another technical problem to be solved by the present invention is to provide a production process method for steel plate counterweight dumbbells, comprising the following steps:

[0012] Step 1: First, install and fix the handheld sleeve in the middle of the handle side wall, and roll the flower on the handheld sleeve part of the handle to form an anti slip mesh surface;

[0013] Step 2: Use a machine tool to create threaded grooves on both ends of the handle's side wall, and also create threaded grooves on the inner side of the locking component that match the handle's side wall, so that the locking component can be installed on the handle's side wall;

[0014] Step 3: Merge multiple steel plates together using screws or riveting to form a weight bell, and then combine a set of dumbbells using multiple combined weight bell pieces. The weight of the dumbbells can be adjusted by replacing the combination pieces to adjust the user's product weight;

[0015] Step 4: Cut and process the dumbbell rings composed of multiple steel plates to achieve the shape of a disc. Then, use a polishing machine to polish and deburr the disc-shaped rings. Finally, use a punching machine to drill holes in the middle of the rings, and the size of the holes should match the end face size of the handle;

[0016] Step 5: Cut the two ends of the dumbbell ring using a cutting machine to complete the formation of the signboard;

[0017] Step 6: Use the installation hole in the middle of the dumbbell ring to install it on both ends of the handle, and then install the locking element through internal and external threads, so that the locking element is supported on one end of the dumbbell ring and the other end of the dumbbell ring is supported on one end of the handheld sleeve, thus completing the support and fixation.

[0018] Compared with the existing technology, the present invention provides a steel plate counterweight dumbbell and its production process and method, which has the following beneficial effects:

[0019] The steel plate counterweight dumbbell and its production process and method combine multiple steel plates with screws or riveting to form a weight bell plate, and then combine a group of dumbbells with multiple combined weight bell plates. The weight of the dumbbells can be adjusted by replacing the combination plates to adjust the user's product weight, and then installed through a handle, handheld sleeve, dumbbell bell bell plate, and locking piece to form an integrated structure dumbbell. This makes the production process of the steel plate counterweight dumbbell simpler and easier to operate, not only reducing the production cost of dumbbells, but also reducing environmental pollution during the production of dumbbells.BRIEF DESCRIPTION OF DRAWINGS
