Problems solved by technology

At present, in order to improve the stability of the barbell, the arrangement of the bell plates adopts the method of decreasing from the inside to the outside; when a large bell plate needs to be added, all the bell plates on the barbell need to be removed and reinstalled; not only waste a lot of time, and the bell plate is prone to fall during the disassembly process, resulting in injury to the personnel's feet; therefore, there is an urgent need for a safe weight device for fitness equipment

Embodiment 1

[0028] like figure 1 As shown, a weight device for fitness equipment includes: a base 1; a weight box 2, which is arranged at one end of the base 1, and the weight box 2 is fixedly connected to the base 1 for storing bell pieces; The plate assemblies are symmetrically arranged at both ends of the inside of the counterweight box 2, and are used to realize automatic weighting on the barbell; the modularized bells can be assembled flexibly, which not only avoids disassembly of the bells, but also improves the installation efficiency; the modular The bell piece assembly includes: two half-ring inner pieces 3 symmetrically arranged on the upper and lower sides of the inside of the counterweight box 2; two half-ring outer pieces 4 symmetrically arranged on the outer side of the The sheet 4 is detachably connected to the half-ring inner sheet 3 and is connected to the inner wall of the counterweight box 2; the installation mechanism is arranged on the half-ring outer sheet 4 and the ...

Embodiment 2

[0031] In order to further improve the convenience of installation, the barbell bar is counterweighted by setting the connecting pipe to connect with the half-ring outer piece and the half-ring inner piece, and rotating the connecting pipe thread to move to different positions to connect the half-ring outer piece and the connecting plate.

[0032]Preferably, the installation mechanism includes two through holes 21 symmetrically opened on the half-ring inner sheet 3 on the side close to the half-ring outer sheet 4, and the half-ring outer sheet 4 is also symmetrically opened with two threaded holes 22 and connected with the through holes 21. The holes 21 are concentric, and the end of the through hole 21 close to the half-ring outer sheet 4 is provided with a connecting pipe 23. The through hole 21 is located on the side of the connecting pipe 23 away from the threaded hole 22 and is provided with an annular recessed groove 24. The annular recessed groove 24 is provided with a li...

Embodiment 3

[0035] In order to further improve the operation convenience of the counterweight device, an automated stepping motor and a first cylinder are used to drive the hexagonal rod to rotate the connecting pipe; in addition, the travel switch can detect the position information of the connecting pipe to ensure the stability of the fixation.

[0036] Preferably, the drive mechanism includes a plurality of stepper motors 41 that are evenly and symmetrically arranged on the upper and lower sides of the counterweight box 2. The output shafts of the stepper motors 41 pass through the counterweight box 2 and are connected to the hexagonal rod 26. Two supporting plates 42 are symmetrically arranged between the feeding motors 41. The supporting plates 42 are vertically and fixedly connected to the counterweight box 2. The stepping motor 41 is slidingly connected to the supporting plates 42. A connecting rod 43 is arranged between the two supporting plates 42. The plate 42 is provided with a ...

Abstract

The invention relates to a counterweight device for fitness equipment, belonging to the technical field of fitness equipment, comprising: a base, a counterweight box arranged at one end of the base, and the counterweight box is fixedly connected with the base for storing bell pieces; multiple modular bell pieces The components are symmetrically arranged at both ends of the counterweight box, and are used to realize automatic counterweight on the barbell; the modular bell plate assembly includes: two half-ring inner pieces, which are symmetrically arranged on the upper and lower sides of the counterweight box; Two half-ring outer sheets are respectively symmetrically arranged on the outside of the half-ring inner sheet, and the half-ring outer sheet and the half-ring inner sheet are detachably connected and connected with the inner wall of the counterweight box; the present invention consists of a half-ring inner sheet and a half-ring outer sheet The counterweight bell plate can be quickly assembled inside the counterweight box, avoiding the need to disassemble the bell plate installed in the front when adding the bell plate, and improving the safety of personnel training; the device of the present invention is simple to operate, convenient to use, and practical Strong and worthy of promotion.

Description

technical field [0001] The invention belongs to the technical field of fitness equipment, and in particular relates to a weighting device for fitness equipment. Background technique [0002] With the development of society and the advancement of technology, people's working conditions and labor intensity have been significantly improved. The jobs with poor working conditions and high labor intensity are basically replaced by machines, and commuting and travel are also basically replaced by motor vehicles. However, people's physical quality is getting worse and worse, and there are more and more sub-health and obese people; due to the increasing impact of environmental pollution, in order to enhance physical fitness, many outdoor fitness activities are also transferred to indoor sports, indoor sports fitness Equipment has developed rapidly. There are many types of indoor sports and fitness equipment with different fitness functions; for example, barbells are widely used, whe...
