Auxiliary noise reduction components are arranged on both side surfaces of the noise reduction housing. Through holes are formed in the front and back surfaces of the noise reduction housing, and lubricating components are arranged on the outer edges of the through holes. An oil storage component is arranged on the top surface of the noise reduction housing.
[0007] As described above, the noise reduction component includes sound-absorbing cotton and sound-absorbing foam boards. The sound-absorbing foam boards are fixedly installed on the inner wall of the noise reduction housing. The sound-absorbing foam boards and the housing of the bidirectional flat cylinder body form an inner cavity, and a number of sound-absorbing cottons are filled in the inner wall of the inner cavity. The sound-absorbing cottons are in contact with the housing of the bidirectional flat cylinder body.
[0008] As described above, the auxiliary noise reduction component includes a damping telescopic rod and a connecting frame. The connecting frames are respectively fixedly installed on both side surfaces of the noise reduction housing, and the damping telescopic rods are fixedly installed on the inner walls of the connecting frames.
[0009] As described above, the movable end of the damping telescopic rod is fixedly connected to the back surface of the connecting plate.
[0010] As described above, the lubrication assembly includes a conical tube, an oil-absorbing sponge, an oil sump, and an oil delivery hose. The conical tubes are respectively fixedly installed on the outer eaves of two holes of the noise reduction housing. An oil sump is provided inside the conical tube.

[0014] First, through the provided noise reduction housing, connecting columns, sound-absorbing cotton, sound-absorbing foam board, connecting frame, connecting plate, and damping telescopic rod in the present utility model, when the two-way flat cylinder body is in use, the pneumatic noise generated inside it can be absorbed by the sound-absorbing cotton and the sound-absorbing foam board, so that most of the noise has been lost when it is conducted to the outside of the noise reduction housing. At the same time, when the movable end of the two-way flat cylinder body expands and contracts, the damping telescopic rod on the connecting frame will be driven to expand and contract together through the connecting plate, thereby buffering the movable end of the two-way flat cylinder body, further reducing the noise, and greatly reducing the noise generated when the two-way flat cylinder body is in use.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0022] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0023] As Figures 1-4 shown, the present utility model provides a technical solution: a bidirectional telescopic cylinder, including a bidirectional flat cylinder body 1, a noise reduction component is arranged on the outer surface of the bidirectional flat cylinder body 1, one end of the movable rod of the bidirectional flat cylinder body 1 is provided with a screw rod, and the screw rod is fixedly connected with a connecting plate 2 through a fixing nut;
[0024] The noise reduction component includes a noise reduction housing 5 and a connecting column 15. A plurality of connecting columns 15 are fixedly installed on both side surfaces of the inner wall of the noise reduction housing 5. The side end of the connecting column 15 is fixedly connected with the side surface of the housing of the bidirectional flat cylinder body 1. The noise reduction housing 5 covers the bidirectional flat cylinder body 1. A noise reduction component is arranged on the inner wall of the noise reduction housing 5.

An oil storage component is arranged on the top surface of the noise reduction housing 5.
[0025] According to the overall structure of the device, before the double-sided flat cylinder body 1 is used, lubricating oil is input into the oil storage tank 13. When the double-sided flat cylinder body 1 is in use, the lubricating oil in the oil storage tank 13 is input into the oil groove 10 of the conical tube 8 through the oil delivery hose 11 by the micro diaphragm pump 12 and absorbed by the oil-absorbing sponge 9. When the movable end of the double-sided flat cylinder body 1 expands and contracts, the oil-absorbing sponge 9 will be squeezed, so that the lubricating oil absorbed by the oil-absorbing sponge 9 is evenly extruded onto the surface of the movable end of the double-sided flat cylinder body 1 for lubrication, thereby preventing the movable end of the double-sided flat cylinder body 1 from malfunctioning during expansion and contraction. Moreover, when the double-sided flat cylinder body 1 is in use, the pneumatic noise generated inside it can be absorbed by the sound-absorbing cotton 6 and the sound-absorbing foam board 7, so that most of the noise has been dissipated when it is transmitted to the outside of the noise reduction housing 5. At the same time, when the movable end of the double-sided flat cylinder body 1 expands and contracts, the connecting plate 2 will drive the damping telescopic rod 4 on the connecting frame 3 to expand and contract together, thereby buffering the movable end of the double-sided flat cylinder body 1, further reducing the noise, and greatly reducing the noise generated when the double-sided flat cylinder body 1 is in use.
[0026] As Figure 2 shown, the noise reduction component includes the sound-absorbing cotton 6 and the sound-absorbing foam board 7. The sound-absorbing foam board 7 is fixedly installed on the inner wall of the noise reduction housing 5. The sound-absorbing foam board 7 and the housing of the double-sided flat cylinder body 1 form an inner cavity, and the inner wall of the inner cavity is filled with a plurality of sound-absorbing cottons 6, and the sound-absorbing cotton 6 is attached to the housing of the double-sided flat cylinder body 1.
[0027] By providing the sound-absorbing cotton 6 and the sound-absorbing foam board 7, when the double-sided flat cylinder body 1 is in use, the pneumatic noise generated inside it can be absorbed by the sound-absorbing cotton 6 and the sound-absorbing foam board 7, so that most of the noise has been dissipated when it is transmitted to the outside of the noise reduction housing 5.
[0028] As Figure 1 shown, the auxiliary noise reduction component includes the damping telescopic rod 4 and the connecting frame 3. The connecting frame 3 is respectively fixedly installed on both side surfaces of the noise reduction housing 5. The damping telescopic rod 4 is fixedly installed on the inner wall of the connecting frame 3, and the movable end of the damping telescopic rod 4 is fixedly connected to the back surface of the connecting plate 2.
[0029] By providing the damping telescopic rod 4 and the connecting frame 3, when the movable end of the double-sided flat cylinder body 1 expands and contracts, the connecting plate 2 will drive the damping telescopic rod 4 on the connecting frame 3 to expand and contract together, thereby buffering the movable end of the double-sided flat cylinder body 1, further reducing the noise.
[0030] As Figures 3-4As shown in the figure, the lubrication assembly includes a conical tube 8, an oil-absorbing sponge 9, an oil sump 10, and an oil delivery hose 11. The conical tube 8 is fixedly installed on the outer eaves of two holes of the noise reduction housing 5 respectively. An oil sump 10 is provided inside the conical tube 8. An installation groove is provided on the inner wall of the conical tube 8, and the installation groove communicates with the oil sump 10. An oil-absorbing sponge 9 is fixedly installed on the inner wall of the installation groove of the conical tube 8. An oil hole is penetrated through the arc surface of the conical tube 8, and an oil delivery hose 11 is fixedly connected to the inner wall of the oil hole. The oil storage assembly includes an oil storage tank 13, a micro diaphragm pump 12, and a shunt tube 14. The oil storage tank 13 is fixedly installed on the top surface of the noise reduction housing 5. An oil outlet is penetrated through the top surface of the oil storage tank 13, and a micro diaphragm pump 12 is fixedly installed on the outer eaves of the oil outlet. The liquid outlet of the micro diaphragm pump 12 is fixedly connected to a shunt tube 14. An oil inlet is penetrated through the arc surface of the oil storage tank 13, and a threaded protrusion is fixedly connected to the outer eaves of the oil inlet. A sealing cover is threadedly connected to the threaded protrusion surface of the oil storage tank 13. Both shunt ends of the shunt tube 14 are fixedly connected to one end of two oil delivery hoses 11.
[0031] By providing the conical tube 8, the oil-absorbing sponge 9, the oil sump 10, the oil delivery hose 11, the oil storage tank 13, the micro diaphragm pump 12, and the shunt tube 14, before the double-sided flat cylinder body 1 is used, lubricating oil is input into the oil storage tank 13. When the double-sided flat cylinder body 1 is in use, the lubricating oil in the oil storage tank 13 is input into the oil sump 10 of the conical tube 8 through the oil delivery hose 11 by the micro diaphragm pump 12 and is absorbed by the oil-absorbing sponge 9. When the movable end of the double-sided flat cylinder body 1 expands and contracts, the oil-absorbing sponge 9 will be squeezed, so that the lubricating oil absorbed by the oil-absorbing sponge 9 is evenly extruded onto the surface of the movable end of the double-sided flat cylinder body 1 for lubrication, thereby preventing the movable end of the double-sided flat cylinder body 1 from malfunctioning during expansion and contraction.
[0032] Working principle: Before the double-sided flat cylinder body 1 is used, lubricating oil is input into the oil storage tank 13. When the double-sided flat cylinder body 1 is in use, the lubricating oil in the oil storage tank 13 is input into the oil sump 10 of the conical tube 8 through the oil delivery hose 11 by the micro diaphragm pump 12 and is absorbed by the oil-absorbing sponge 9. When the movable end of the double-sided flat cylinder body 1 expands and contracts, the oil-absorbing sponge 9 will be squeezed, so that the lubricating oil absorbed by the oil-absorbing sponge 9 is evenly extruded onto the surface of the movable end of the double-sided flat cylinder body 1 for lubrication. And when the double-sided flat cylinder body 1 is in use, the pneumatic noise generated inside it can be absorbed by the sound-absorbing cotton 6 and the sound-absorbing foam board 7. At the same time, when the movable end of the double-sided flat cylinder body 1 expands and contracts, the damping telescopic rod 4 on the connecting frame 3 will be driven to expand and contract together by the connecting plate 2, thereby buffering the movable end of the double-sided flat cylinder body 1.
