Preferably, the side of the piston is socketed a piston bush.
Preferably, being provided with thread pore structure in the installation pedestal.
Preferably, two ports of export of the three-way pipeline connect two ports of the connecting pipe, the threeway One entrance point of pipeline connects the bleed port of the hydraulic oil pump.
Compared with prior art, the beneficial effects of the utility model are:The utility model simple structure, regulation process letter It is single, can realize being adjusted in synchronism, and being completely embedded property between part is preferably, improves security during using the device.
Brief description of the drawings
Fig. 1 is a kind of structural representation of the adjustable horizontal bar of physical culture of the utility model;
In figure:1. the first open tubular column, 2. the second open tubular column, 3. installation pedestal, 4. connecting pipe, 5. three-way pipeline, 6. liquid Pressure oil pump, 7. hollow-core construction, 8. piston, 9. support bar, 10. helical spring, 11. transverse bars.
Specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made The every other embodiment for being obtained, belongs to the scope of the utility model protection.
Refer to Fig. 1, a kind of embodiment that the utility model is provided:A kind of adjustable horizontal bar of physical culture, including first One group of installation pedestal 3, institute are fixed in the open tubular column 2 of open tubular column 1 and second, the bottom of the open tubular column 2 of first open tubular column 1 and second The inside for stating the first open tubular column 1 and the second open tubular column 2 is respectively provided with a hollow-core construction 7, and first open tubular column 1 and second is hollow A connecting pipe 4 is fixed in the bottom of the outer surface of post 2, and the inside of the connecting pipe 4 connects the bottom of the hollow-core construction 7 Portion, two connecting pipes 4 connect a bleed port for hydraulic oil pump 6, two hollow-core constructions by a three-way pipeline 5 One group of piston 8 is placed in 7 inside respectively, and the center of the upper surface of the piston 8 fixes one through the first open tubular column 1 and second A transverse bar 11 is fixed at the support bar 9 of open tubular column 2, the top of two support bars 9, and two support bars 9 are being located at Body of rod set between the upper surface and the top of hollow-core construction 7 of piston 8 puts a helical spring 10.
The structure of first open tubular column 1 is identical with the structure of the second open tubular column 2;The side of the piston 8 is socketed a work Sealing space is formed between plug sleeve, and the inwall of hollow-core construction 7, hydraulic fluid leak is prevented;Screw thread is provided with the installation pedestal 3 Pore structure, the convenient fixation to the device;Two ports of export of the three-way pipeline 5 connect two ends of the connecting pipe 4 Mouthful, an entrance point of the three-way pipeline 5 connects the bleed port of the hydraulic oil pump 6, realizes the annexation of three.
