Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of kettlebell processing, in particular to a kettlebell that is anti-drop and not easily damaged. Background Art
[0002] There are two existing products on the market, soft kettlebells and hard kettlebells, both of which have technical defects. The existing hard kettlebell is first blow-molded to form a hard plastic shell of the kettlebell, then filled with concrete, and finally sealed. The structure is a single-layer hard plastic wrapping hardened solid concrete, and the concrete completely fills the hard plastic kettlebell shell.
[0003] The existing soft kettlebell needs to first injection-mold or blow-mold a hard plastic handle of the kettlebell, then injection-mold a soft plastic kettle body for containing iron sand, fill the soft plastic kettle body with fine iron sand particles and then seal it, and then bond the hard plastic handle and the soft plastic kettle body together. The structure is that the kettle body is wrapped with soft plastic containing granular iron sand, and the handle is a hollow hard plastic.
[0004] Due to the relatively high hardness of concrete and the fact that the kettlebell will directly hit hard objects such as the ground, there are disadvantages such as being afraid of being dropped and broken, and the harm to users and the site caused by misoperation is relatively large.
[0005] For the structure of the existing soft kettlebell with soft plastic wrapping granular iron sand, on the one hand, the production cost is relatively high. On the other hand, since it is iron sand, it cannot fill the inside of the kettlebell and is in a granular state, so it is easy to shake during use, resulting in the user's center of gravity shifting and instability; the soft kettlebell is often beaten during use, and after a period of use, the originally sealed sand-filling port will leak air, resulting in the deformation of the kettle body and sand leakage, with a high damage rate and a short service life.
[0006] The utility model combines the soft kettlebell and the hard kettlebell to design a kettlebell that is anti-drop and not easily damaged. Utility Model Content
[0007] The main purpose of the utility model is to provide a kettlebell that is anti-drop and not easily damaged, so as to effectively solve the problems raised in the background art.
[0008] To achieve the above purpose, the utility model adopts the following technical solution: a kettlebell that is anti-drop and not easily damaged, including a hard plastic shell, a hard plastic plug, a soft plastic shell, and a concrete filler; the lower part of the hard plastic shell is spherical with a hollow handle on it, and a through hole is provided in the center of the lower part of the hard plastic shell, and the through hole is blocked by a hard plastic plug. The spherical outer shell of the lower part of the hard plastic shell shrinks inward by 4 - 6 mm from below 1 / 3 of its height, and a layer of soft plastic shell is sleeved outside the shrunk part. The outer surface of the soft plastic shell is flush with the outer surface of the upper part of the sphere, forming a spherical whole.
[0009] Preferably, all the spaces inside the hard plastic shell are filled with concrete filler.
[0010] Preferably, the hard plastic shell is formed by blow molding, and the soft plastic shell is formed by injection molding.
[0011] Advantages of the present utility model: effectively solve the disadvantages that the blow-molded hard kettlebell is afraid of being dropped, smashed and easily damaged, and the harm to users and the venue after misoperation is relatively large; using concrete filler instead of iron sand reduces the production cost of the soft kettlebell, solves the problem of the internal filler shaking of the soft kettlebell, and the thickened kettle body can also greatly reduce the damage rate of the soft kettlebell. Brief Description of the Drawings
[0012] Appendix Figure 1 is a schematic structural diagram of the present utility model.
[0013] Appendix Figure 1 In it, there are a hard plastic shell 1, a hard plastic plug 2, a soft plastic shell 3, and a concrete filler 4. Detailed Embodiments
[0014] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in combination with the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present utility model.
[0015] Embodiment 1
[0016] Appendix Figure 1 As shown, a kettlebell that is anti-drop and not easily damaged includes a hard plastic shell 1, a hard plastic plug 2, a soft plastic shell 3, and a concrete filler 4; the lower part of the hard plastic shell 1 is spherical with a hollow handle on it. There is a through hole in the center of the lower part of the hard plastic shell 1, and the through hole is blocked by a hard plastic plug 2. The spherical outer shell of the lower part of the hard plastic shell 1 shrinks inward by 6 mm from below 1 / 3 of its height. A layer of soft plastic shell 3 is sleeved outside the shrunk part, and the outer surface of the soft plastic shell 3 is flush with the outer surface of the upper part of the sphere, forming a spherical whole.
[0017] All the spaces inside the hard plastic shell 1 are filled with the concrete filler 4.
[0018] The hard plastic shell 1 is formed by blow molding, and the soft plastic shell 3 is formed by injection molding.
[0019] Advantages of the present utility model: effectively solve the disadvantages that blow-molded hard kettlebells are afraid of being dropped, smashed and easily damaged, and the harm to users and the venue caused by misoperation is relatively large; using concrete filler instead of iron sand reduces the production cost of soft kettlebells, solves the problem of shaking of the internal filler of soft kettlebells, and the thickened kettle body can also greatly reduce the damage rate of soft kettlebells.
[0020] Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
