Description
Technical field
The utility model relates to the syndeton between a kind of pipe fitting and the pipe fitting, relates in particular to the syndeton between the pipe fitting and column in a kind of body-building apparatus.
Background technology
People more and more pay attention to body-building and exercise, and a lot of residential quarters are supporting some public body-building apparatus that are provided with all, and utilization rate at ordinary times is also very high, such as horizontal bar, wab board, duplex spacewalk machine, flat stool, flat ladder etc.This outdoor body-building apparatus material generally all comprises at least two columns of fixing with the bottom surface, and the top between two columns is provided with crossbeam, and crossbeam generally adopts the less tubing of diameter to make, and namely the diameter of crossbeam tubing is less than the diameter of column tubing.
Pipe fitting generally is connected in the following ways with column in the existing body-building apparatus, offer jack at the column sidewall, then pipe fitting is plugged in the jack, adopting at last welding manner to be welded and fixed between pipe fitting periphery and jack inwall, is that the Chinese utility model patent " a kind of Novel single air walker " of ZL201020267662.2 (notification number is CN201783135U) discloses the syndeton between a kind of pipe fitting and the column such as a patent No.; Also have plenty of the upper end open of the end of pipe fitting being inserted column downwards, and then weld together between the outer peripheral face with column inner hole wall and crossbeam.
There is following defective in aforementioned connected mode: crossbeam tubing stressed only depends on that lap welding seam bears between the outer peripheral face of column inner hole wall and crossbeam, and holding capacity is little; The rigid connection place easily causes wedge angle between pipe fitting and the column, and wedge angle can bring clip and user's the risk of colliding with, and affects the outward appearance of product.
Summary of the invention
Technical problem to be solved in the utility model is that the syndeton between the pipe fitting and column in a kind of body-building apparatus that can eliminate the junction wedge angle is provided for above-mentioned prior art present situation.
The utility model solves the problems of the technologies described above the technical scheme that adopts: the syndeton in a kind of body-building apparatus between pipe fitting and the column, comprise column and pipe fitting, the diameter of column is greater than the caliber of pipe fitting, it is characterized in that: also include end socket, the internal diameter of the lower openings of this end socket and the external diameter of column match, the internal diameter of the upper opening of end socket and the external diameter of pipe fitting match, the lower openings of described end socket is set in the upper end of column and welds together, and the lower end of pipe fitting is plugged in the upper opening of end socket and welds together.
Improve further, the top of above-mentioned column endoporus is welded with stiffener, and described pipe fitting lower end is passed to enter behind the upper opening of end socket and fitted with described stiffener in the column again and weld together.Being welded on the interior stiffener of column has increased the strong point of pipe fitting, therefore the stress point of pipe fitting not only has the pad between pipe fitting and the end socket, also increase stiffener to the support of pipe fitting, greatly strengthen the fixing of the syndeton between pipe fitting and the column, strengthened the intensity of structure.
The profile of above-mentioned stiffener and column endoporus profile match, and the border welds together between the inner hole wall of stiffener periphery and column.Owing to adopting the border welding between stiffener and the column inner hole wall, stiffener can firmly be fixed with column, has further strengthened the intensity of structure, and stiffener also can be the runway shape certainly.
Above-mentioned end socket has the cambered surface section that is bowl-shape, the bottom of described cambered surface section has the lower annular wall to downward-extension, this time annular wall surrounds the lower openings of described end socket, and the top of described cambered surface section has upwardly extending upper annular wall, and annular wall surrounds the upper opening of described end socket on this.Its centre of the overall structure of end socket is arc transition, the wedge angle that rigid connection causes in the middle of better preventing, and the more effective clip that wedge angle brings, the equivalent risk that collides with removed of energy, product becomes streamlined in addition, and is handsome in appearance generous.
The upper opening of above-mentioned end socket is rounded, and the cross section of described pipe fitting is also rounded.The upper opening ovalize of above-mentioned end socket, the cross section of described pipe fitting is ovalize also.The profile of end socket upper opening and pipe fitting profile are suitable.
Compared with prior art, the utility model has the advantage of: end enclosure structure is set up in the junction between pipe fitting and the column, end socket can coat the link position between pipe fitting and the column, the wedge angle that causes of rigid connection in the middle of preventing has effectively been removed the clip that wedge angle brings, equivalent risk collides with.

The specific embodiment
Embodiment is described in further detail the utility model below in conjunction with accompanying drawing.
As shown in Figure 1, 2, be first embodiment of the present utility model.
Syndeton in a kind of body-building apparatus between pipe fitting and the column comprises column 1 and pipe fitting 2, and the diameter of column 1 is greater than the caliber of pipe fitting 2.
Also include end socket 3, the internal diameter of the lower openings 4 of this end socket 3 and the external diameter of column 1 match, the internal diameter of the upper opening 5 of end socket 3 and the external diameter of pipe fitting 2 match, end socket adopts the t2 steel plate punched to form, whole one-tenth arc transition, end socket 3 has the cambered surface section 31 that is bowl-shape, the bottom of cambered surface section 31 has the lower annular wall 32 to downward-extension, this time annular wall 32 surrounds the lower openings 4 of end socket, the top of cambered surface section 31 has upwardly extending upper annular wall 33, and annular wall 33 surrounds the upper opening 5 of described end socket on this.The lower openings 4 of end socket 3 is set in the upper end of column 1 and welds together, and the lower end of pipe fitting 2 is plugged in the upper opening 5 of end socket and welds together.The upper opening 5 of end socket is rounded in the present embodiment, and the cross section of pipe fitting 2 is also rounded, and the main specifications of pipe fitting 2 is divided into φ 32, φ 42, φ 60 is several.
The top of column 1 endoporus is welded with stiffener 6, and the profile of stiffener 6 and column 1 endoporus profile match, and the border welds together between the inner hole wall of stiffener 6 peripheries and column 1.Pipe fitting 2 lower ends are passed to enter behind the upper opening 5 of end socket and are fitted with described stiffener 6 in the column 1 again and weld together.
Shown in Fig. 3,4, be second embodiment of the present utility model.
The difference of this embodiment and first embodiment is: upper opening 5 ovalizes of end socket, and the cross section of pipe fitting 2 is ovalize also, and pipe fitting 2 uses for flat ellipse pipe 60*30 tubing.The stress point of pipe fitting not only has the pad between pipe fitting and the end socket, also increases stiffener to the support of pipe fitting, greatly strengthens the fixing of the syndeton between pipe fitting and the column, has strengthened the intensity of structure.
