Description

Technical Field

[0001] The present invention belongs to the technical field of compressors, and particularly relates to a piston rod component applicable to a gas compressor. Background Art

[0002] A gas compressor is a power device that converts mechanical energy into gas pressure energy. It is commonly used to provide gas power for pneumatic tools and is also often used to compress media such as oxygen, hydrogen, ammonia, natural gas, coke oven gas, and inert gas in industries such as petrochemical, drilling, and metallurgy.

[0003] Since the cylinder of the compressor mainly uses lubricating oil to maintain airtightness and smooth sliding, the piston assembly of a conventional compressor cannot store lubricating oil and needs to be frequently maintained and replenished with lubricating oil, resulting in a relatively short lubrication durability of the piston assembly of the conventional compressor.

[0004] Therefore, we propose a piston rod component applicable to a gas compressor to solve the above problems. Summary of the Invention

[0005] The purpose of the present invention is to solve the problem of relatively short lubrication durability of the piston assembly of a conventional compressor, and to propose a piston rod component applicable to a gas compressor.

[0006] To achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A piston rod component applicable to a gas compressor includes a first gland. A rod body is installed at the lower part of the first gland through screws. A collar is clamped between the first gland and the rod body. A connecting seat is rotatably installed at the lower part of the rod body. A housing is buckled at the lower part of the connecting seat. An oil box is sleeved inside the housing. An annular leather sheet is clamped between the housing and the oil box. There are a pair of annular leather sheets. A second gland is buckled at the lower part of the oil box. A sealing ring is clamped between the housing and the connecting seat. There are two sealing rings. One of the sealing rings is clamped between the oil box and the second gland. A bolt is threadedly installed on the outside of the housing. The bolt is embedded in the oil box. A leather cover is embedded in the housing. The leather cover blocks the bolt. Pull out the leather cover, then screw out the bolt, then disassemble the housing and the oil box, add oil into the oil box, then dock the oil box with the housing, screw the bolt back, and use the bolt to lock the oil box and the housing. During the working process, use the annular leather sheet to guide the oil into the space between the cylinder and the sealing ring, which is convenient for automatic lubricating oil replenishment.

[0008] Preferably, the first gland includes a cover body and a first buckle strip. The first buckle strip is fixedly connected to the inner side wall of the upper part of the cover body. After docking the cover body with the rod body, use the first buckle strip to clamp on the collar to prevent deflection between the collar and the cover body and improve the stability of the collar angle.

[0009] Preferably, the rod body includes a socket and a second buckle strip. A connecting rod is fixedly connected to the lower end of the socket, and the second buckle strip is fixedly connected to the middle of the socket. The collar is stuck on the second buckle strip, and the socket is used to restrain the collar. At the same time, the second buckle strip is used to prevent the collar from deflecting. At the same time, the first gland is used to prevent the collar from deflecting with the first gland and the rod body, ensuring the stability among the first gland, the rod body, and the collar.

[0010] Preferably, the connecting seat includes a seat body. A spring piece is fixedly connected to the lower end of the seat body, and a first buckle block is fixedly connected to the lower end of the spring piece. The first buckle block is in a buckling match with the upper part of the housing. The first buckle block is buckled inside the housing to keep the first buckle block in docking with the housing. The seat body is rotated, and the spring piece is driven by the seat body to revolve. The first buckle block is driven by the spring piece to move inside the housing, causing the first buckle block to be misaligned with the buckle groove of the housing, and the first buckle block is disengaged from the housing, and then the connecting seat is removed, facilitating the replacement of the upper sealing ring.

[0011] Preferably, the bolt includes a plug bolt. One end of the plug bolt is fixedly connected to a bolt body, and the bolt body is threadedly installed inside the housing. The bolt body is screwed into the housing, and the plug bolt is stably embedded in the oil box through the bolt body, facilitating the docking of the oil box and the housing.

[0012] Preferably, the leather cover includes a cover body. A first plug block is fixedly connected to the side of the cover body. The first plug block is inserted into the bolt body, and the cover body is embedded in the housing. The first plug block is stuck in the bolt body, and at the same time, the cover body is stuck on the housing, so that the cover body and the first plug block block the bolt, preventing the bolt from loosening outwards excessively and improving the stability of the bolt in the assembled state.

[0013] Preferably, the oil box includes a box body. An annular groove is formed in the upper part of the box body. The plug bolt is inserted into the annular groove. An oil hole is formed in the side of the box body. The annular leather piece is sleeved outside the oil hole, and the lower end of the housing presses on the annular leather piece. The plug bolt is inserted into the annular groove to keep the box body inside the housing, so that the two annular leather pieces guide the oil in the oil hole to supply the target oil cylinder, facilitating automatic oil replenishment.

[0014] Preferably, the second gland includes a second buckle block. A elastic plate is fixedly connected to the lower end of the second buckle block, and a baffle is fixedly connected to the lower end of the elastic plate. The baffle presses on the lower end of one of the sealing rings. A hexagonal groove is formed in the lower end of the baffle, and the second buckle block is buckled inside the box body. The second buckle block is buckled in the inner notch of the box body, so that the second buckle block is kept at the lower part of the oil box through the elastic plate, and one of the sealing rings is kept on the baffle. The screwdriver is inserted into the hexagonal groove, and then the baffle is rotated to drive the second gland to rotate, causing the second buckle block to be misaligned with the buckle groove at the lower part of the box body, and the second gland is disengaged from the oil box, and the second gland is removed, facilitating the replacement of the sealing ring.

[0015] Preferably, the collar includes a first half-ring and a second half-ring. A third buckle is fixedly connected to the first half-ring, and the third buckle is inserted and matched with the second half-ring. The first half-ring and the second half-ring are clamped between the first gland and the rod body. The second buckle strip is clamped at the lower ends of the first half-ring and the second half-ring. A second insert block is fixedly connected to the outside of the second half-ring, and the second insert block is inserted and matched with the first half-ring. Two sets of first half-rings and second half-rings are spliced with each other to form a complete ring body, and the gaps of the ring are staggered by the first half-ring and the second half-ring to improve the firmness after installation.

[0016] In summary, the technical effects and advantages of the present invention are as follows:

[0017] 1. Pull out the leather cover, then unscrew the bolt, then disassemble the sleeve and the oil box, add oil into the oil box, then dock the oil box with the sleeve, and screw the bolt back to lock the oil box and the sleeve with the bolt. During the working process, the annular leather piece is used to guide the oil into the space between the cylinder and the sealing ring, which is convenient for automatically replenishing lubricating oil.

[0018] 2. Clamp the collar on the second buckle strip, use the socket to restrict the collar, and at the same time use the second buckle strip to prevent the collar from deflecting. At the same time, use the first gland to prevent the collar from deflecting with the first gland and the rod body, so as to ensure the stability among the first gland, the rod body and the collar.

[0019] 3. Use the first buckle to buckle inside the sleeve, keep the first buckle docked with the sleeve, rotate the seat body, drive the elastic piece to revolve through the seat body, drive the first buckle to move along the inside of the sleeve through the elastic piece, so that the first buckle is misaligned with the buckle groove of the sleeve, and the sleeve is disengaged from the first buckle, and then remove the connecting seat, which is convenient for replacing the upper sealing ring.

[0020] 4. Screw the bolt body into the sleeve, and stably embed the bolt in the oil box through the bolt body, which is convenient for keeping the oil box docked with the sleeve.

[0021] 5. Use the first insert block to be stuck in the bolt body, and at the same time use the cover to be stuck on the sleeve, so that the cover and the first insert block block the bolt to prevent the bolt from loosening outwards excessively, and improve the stability of the bolt in the assembled state.

[0022] 6. Use the bolt to be inserted into the annular groove to keep the box body in the sleeve, so that the two annular leather pieces guide the oil in the oil hole to the target oil cylinder, which is convenient for automatic oil replenishment.

[0023] 7. Use the second buckle to buckle in the inner notch of the box body, so that the second buckle is kept at the lower part of the oil box through the elastic plate, keep one of the sealing rings on the baffle, insert the screwdriver into the hexagonal groove, and then rotate the baffle to drive the second gland to rotate, so that the second buckle is misaligned with the buckle groove at the lower part of the box body, and the second gland is disengaged from the oil box, and then remove the second gland, which is convenient for replacing the sealing ring.

[0024] 8. Two groups of first half-rings and second half-rings are spliced with each other to form a complete ring body. The first half-ring and the second half-ring are used to stagger the gaps of the ring, thereby improving the firmness after installation. BRIEF DESCRIPTION OF THE DRAWINGS
