Description

Stepless adjusting counterweight arm

Technical Field

The utility model relates to a body-building apparatus field particularly, relates to a infinitely variable control counter weight arm.

Background

With the economic development and social progress, fitness equipment is more and more popular, and the variety of fitness equipment is various, but most fitness equipment comprises two parts from the viewpoint of equipment structure: an action member and a weight member. Most of the seed distributing arms on the existing fitness equipment adopt the traditional hanging piece type or the balancing weight, the balancing weight is increased or reduced manually during adjustment, the adjustment process is complicated, the operation is not easy, the weight is easy to lose, and the use comfort of the fitness equipment is influenced.

SUMMERY OF THE UTILITY MODEL

The utility model discloses a main aim at overcomes the above-mentioned not enough of current counter weight part, provides a infinitely variable control counter weight arm.

In order to achieve the above object, the utility model adopts the following technical scheme:

the stepless-adjustment counterweight arm comprises a base, counterweight barrels and U-shaped pipes, wherein two ends of the base are respectively fixed with one counterweight barrel, counterweight materials are arranged in the counterweight barrels, the two counterweight barrels are connected through the U-shaped pipes, and two ends of each U-shaped pipe are provided with a flow limiting device.

Preferably, the flow limiting device comprises a flow limiting plate and a knob, the flow limiting plate is located in the U-shaped pipe and is in a round cake shape, the side face of the flow limiting plate is in an arc shape, the maximum diameter of the flow limiting plate is the same as the inner diameter of the U-shaped pipe, the knob is located outside the U-shaped pipe, a rotating shaft is fixed to the side face of the flow limiting plate, and the rotating shaft extends out of the U-shaped pipe and is fixedly connected with the knob.

Preferably, a fixing hole is arranged in the center of the base between the two counterweight barrels.

Preferably, the counterweight barrel is a steel barrel, and the counterweight material is steel sand.

The utility model discloses following beneficial effect has: the utility model discloses a counter weight arm adopts the flow regulation, can realize stepless regulation, and the regulative mode is simple and convenient, and safe theftproof, is fit for different crowds and uses.

FIG. 3 is a sectional view taken along line A-A of FIG. 2;

FIG. 4 is a schematic view of a flow restriction device;

wherein the figures include the following reference numerals: 1. a base; 2. a counterweight barrel; 3. a U-shaped pipe; 4. a current limiting device; 41. a restrictor plate; 42. a knob; 43. a rotating shaft; 5. and (7) fixing holes.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

As shown in fig. 1-4, infinitely variable control counter weight arm, including base 1, counter weight bucket 2 and U type pipe 3, the both ends of base are fixed with a counter weight bucket respectively, the counter weight material is equipped with in the counter weight bucket, communicate through U type pipe between two counter weight buckets, the both ends of U type pipe all are provided with current limiting device 4, current limiting device includes current-limiting plate 41 and knob 42, current-limiting plate is located U type intraductal, for the cake form, the side is the arc, its maximum diameter is the same with the internal diameter of U type pipe, the knob is located outside the U type pipe, current-limiting plate side is fixed with pivot 43, the pivot is stretched out from U type intraductal, with knob fixed connection.

The fixing hole 5 is formed in the center of the base between the two counterweight barrels, and when the counterweight barrel is used, the counterweight arm is fixed through the fixing hole 5, so that the counterweight arm can freely rotate around the position of the fixing hole, and counterweight materials can flow into the other counterweight barrel from one counterweight barrel under the action of gravity. The round cake can be rotated by rotating the knob of the flow limiting device, so that the adjustment of different states of flow limitation and flow permission is realized, the flow of the counterweight material in the U-shaped pipe is adjusted, and the purpose of counterweight adjustment is achieved.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
