Abstract

The utility model relates to a combined barbell bar. A standard barbell bar is divided into a plurality of segments, and every two segments are connected together by a casing tube (3); an inner hole of each casing tube and the outer diameter of the barbell bar are in sliding fit, and spring pins (5) or connecting devices using grooving flat ends for fixing screws (8) are arranged in radial positions of the barbell bar and the casing tube. After the barbell bar is divided into segments, the utility model has the advantages of convenient package, transportation, storage, simple and convenient assembly and connection, easy manufacturing, and high safety.

Description

The combined type bar

The utility model belongs to the human body exercising device, relates to a kind of improvement of bar.

Traditional bar is global design, and length is longer, exists the difficulty of aspects such as packing.Long bars such as particularly 60 inches, 70 inches, length surpasses 1.5 meters, and weight is greater than 5 kilograms, and the packing case of this whole bar is not only very long, and heavy, and it is very inconvenient to carry, deposit.In use collide, damage apparatus easily, and jeopardize personal safety.Address this problem, can take the way of sectional making to realize.Generally be that bar is divided into three sections, between with being threaded.The shortcoming of this connected mode is: processing is difficult to guarantee precision, connects cumbersomely during use, and thread segment very easily damages.

The purpose of this utility model is in order to overcome the shortcoming of prior art, a kind of combined type bar to be provided, and is not only instant packed behind the sectional making, carry, deposit, and has assembling and connect the advantage easy, that processing and fabricating is easy, safe and reliable.

The utility model is achieved through the following technical solutions its purpose.A kind of combined type bar is with the segmentation of standard bar, connects with sleeve pipe between two sections, and the external diameter of cover pipe orifice and bar is slidingly matched, and at bar and sleeve pipe jockey is set radially.Described jockey can be radially to process circular hole on bar, lays the spring pin in it, radially also processes the fixedly circular hole of pin on sleeve pipe accordingly.Described jockey also can be on sleeve pipe and the corresponding position of bar, and radially the machining internal thread hole links together them with a fluting flush end holding screw.Described jockey can also be earlier sleeve pipe and one section bar to be welded as a whole, and is disposed radially the spring pin on another section bar, radially also offers the fixedly circular hole of pin accordingly on sleeve pipe.Should leave the gap between the segmentation bar.

The utility model compared with prior art has the following advantages and effect: owing to take the mode of sectional making, therefore when off working state, can be segmented poles with tearing open than long bar, put into packing case, the length that takes up space is little, carries, deposits very convenient.The section of tearing open is packed simultaneously, and part is not fragile.Because the connectivity scenario between the segmentation is taked a kind of threadless casing bit, during use the spring pin is pressed, bar is inserted in the sleeve pipe, rotate a little, the spring pin springs into fixedly and gets final product in the circular hole; Or, aim at screwed hole with in two sections bars insertion sleeve pipes, and be screwed into fluting flush end holding screw and get final product, connect very easy.If adopt with sleeve pipe and one section scheme that bar welds together earlier, only need insert another section bar during use, suit connects convenient.Can once join brill man-hour because the radial hole between sleeve pipe and the bar adds, therefore guarantee that suit is connected with higher precision.Can not make troubles because sleeve pipe is short to use yet.It is easy to the utlity model has processing and fabricating through practicality proof, and assembling connects easy, safe and reliable advantage.

Below by embodiment, the utility model is described in further detail in conjunction with the accompanying drawings.

Fig. 1 is a kind of structural representation of the present utility model;

Fig. 2 is an another kind of structural representation of the present utility model;

Fig. 3 is another structural representation of the present utility model.

As shown in Figure 1, a kind of combined type bar, the whole bar of standard is divided into two sections, be connected with sleeve pipe 3 between a left side bar 1 and the right bar 2, cover pipe orifice and bar external diameter are slidingly matched, left and right bar is radially processed circular hole 4 at matching part, and the built-in pin 5 that has spring radially also is processed with the fixedly circular hole of pin accordingly on sleeve pipe 3.This post means between left and right bar and the sleeve pipe is provided with one group at least respectively, and the 2-3 group can be set as required.Leave gap 6 between left side bar 1 and the right bar 2.

As shown in Figure 2, a kind of combined type bar, the standard bar is divided into two sections, connect with sleeve pipe 3 between left side bar 1 and the right bar 2, the endoporus of sleeve pipe and the external diameter of bar are slidingly matched, radially distinguish machining internal thread hole 7 at matching part left and right sides bar and sleeve pipe, connect with a fluting flush end holding screw 8 respectively.This radially screw connection between left and right sides bar and the sleeve pipe is provided with one group at least respectively, and the 2-3 group also can be set as required.Leave the gap between the bar of the left and right sides.

As shown in Figure 3, a kind of combined type bar, the same Fig. 1 of basic structure, difference is earlier left bar 1 to be welded together with sleeve pipe 3, only radially processes circular hole 4 between right bar 2 and sleeve pipe 3, and places spring pin 5.Leave gap 6 between the bar of the left and right sides.

The number of fragments of combined type bar also can be divided into three sections as required under the situation that does not influence use.

Claims

1, a kind of combined type bar is characterized in that: with the segmentation of standard bar, connect with sleeve pipe (3) between two sections bars (1,2), cover pipe orifice and bar external diameter sliding fit radially are provided with jockey at bar and sleeve pipe.

2, according to the described combined type bar of claim 1, it is characterized in that: the radially jockey between described sleeve pipe and the bar, be on bar, radially to process circular hole (4), place spring pin (5) in it, accordingly the circular hole of fixed processing pin radially on sleeve pipe.

3, according to the described combined type bar of claim 1, it is characterized in that: the radially jockey between described sleeve pipe and the bar, be on sleeve pipe and the corresponding position of bar radially machining internal thread hole (7), connect with fluting flush end holding screw (8).

4, according to the described combined type bar of claim 2, it is characterized in that: the radially jockey between described sleeve pipe and the bar, be that sleeve pipe (3) and one section bar (1) are welded as a whole, spring pin (5) is set on another section bar (2), on sleeve pipe, radially has the fixedly circular hole of pin accordingly.
