Description
- 1. Field of the Invention
- This invention relates to an air compressor structure, and more particularly to one having a main body, a fixing plate and a cap member which are secured together with fasteners to increase its strength so as to minimize vibration when the compressor is working and to prevent the compressor from leakage through an air passage and a chamber.
- 2. Description of Prior Art
- A conventional air compressor comprises a cylinder, a cap member, and a valve located between the cylinder and the cap member to prevent air from backflow into the cylinder. US Patent Publication No. 20090104052 titled “Pump Improvements” discloses a cylinder, a valve connected with the cylinder, and an air tight cap coupled on the valve to prevent air from backflow into the cylinder. However, there are some shortcomings in this application. When a plunger in the cylinder is activated by a motor, it generates a vast vibration which causes a leakage of air from a gap between the air tight cap and the cylinder or a gap between an air tube and a lid. The valve prevents the air form leakage, but it cannot help the air tight cap and the cylinder to operate in a stable status.
- The purpose of the present invention is to improve the leakage caused by vibration during operation.
- According to the present invention, there is provided an air compressor structure, comprising:
- a main body having a pair of cylinders, each of the cylinders comprising a plunger therein and a fixture on an outer wall thereof, the fixture having a pair of first threaded holes thereon;
- a fixing plate comprising a handle and a pair of fixing portions extending from two sides of the handle, the pair of fixing portions corresponding to the pair of cylinders, each fixing portion comprising a fixing section and a recess thereon, the fixing section having a first air sealing ring thereon and being mounted in one of the cylinders of the main body, a second air sealing ring being provided in the recess, the fixing portion being formed with an air hole and a stop plate disposed on top of the air hole, the fixing portion further having a slot thereon and a pair of first lugs which has a pair of second threaded holes corresponding in position to the first threaded holes of the fixture;
- a cap member comprising a tube having an air passage therein, a pair of third air sealing rings at two ends of the tube, and a pair of lids attached to the pair of third sealing rings at the two ends of the tube, the pair of lids corresponding to the pair of fixing portions of the fixing plate, the lids each covering one of the fixing portions and being against the second air sealing ring, the lids each comprising a chamber interconnecting with the air passage of the tube, a stud corresponding to the slot of the fixing portion, and a pair of second lugs corresponding to the pair of first lugs, the second lugs having a pair of third threaded holes corresponding to the first threaded holes and the second threaded holes; and
- fasteners inserting through the third threaded holes, the second threaded holes, and the first threaded holes, respectively, to secure the cover member and the fixing plate to the main body.
- It is the primary object of the present invention to provide an air compressor structure, which uses the fasteners inserting through the first, the second, and the third threaded holes, respectively, to secure the cap member, the fixing plate and the main body together so as to minimize vibration when the compressor is working and to prevent the compressor from leakage through the air passage and the chamber.
- It is another object of the present invention to provide an air compressor structure, which uses the engagement of the slot of the fixture portion and the stud of the lid to enhance the strength of the cap member and the fixing plate as well as the stability of the cap member, the fixing plate and the main body.

FIG. 2 is an exploded view of the present invention; -
FIG. 3 is an exploded view of a cap member of the present invention; -
FIG. 4 is a partially sectional view of the present invention; -
FIG. 5 is a cross-sectional view showing fasteners inserting through first threaded holes, second threaded holes and third threaded holes to secure the cap member, a fixing plate and a main body of the present invention; and -
FIG. 6 is a cross-sectional view of the present invention. - Referring to
FIG. 1 thru 5, the air compressor structure of the present invention comprises amain body 1, afixing plate 2, acap member 3, andfasteners 4. - The
main body 1 has a pair ofcylinders 11. Eachcylinder 11 comprises aplunger 12 therein and afixture 13 on an outer wall thereof. Thefixture 13 has a pair of first threadedholes 14 thereon. - The
fixing plate 2 comprises ahandle 21 and a pair offixing portions 22 extending from two sides of thehandle 21. The pair offixing portions 22 corresponds to the pair ofcylinders 11. Eachfixing portion 22 comprises afixing section 221 and arecess 222 thereon. Thefixing section 221 has a firstair sealing ring 23 thereon and is mounted in thecylinder 11 of themain body 1. A secondair sealing ring 24 is provided in therecess 222. Thefixing portion 22 is formed with anair hole 25 and astop plate 26 disposed on top of theair hole 25 as a cover to prevent air flow through theair hole 25 into thecylinder 11. Thefixing portion 22 further has aslot 27 thereon and a pair offirst lugs 28 which has a pair of second threadedholes 281 corresponding in position to the first threadedholes 14 of thefixture 13. - The
cap member 3 comprises atube 31 having anair passage 311 therein, a pair of thirdair sealing rings 32 at two ends of thetube 31, and a pair oflids 33 attached to the pair ofthird sealing rings 32 at the two ends of thetube 31. The pair oflids 33 corresponds to the pair offixing portions 22 of thefixing plate 2. Eachlid 33 covers thefixing portion 22 and is against the secondair sealing ring 24. Eachlid 33 comprises achamber 331 interconnecting with theair passage 311 of thetube 31, astud 34 corresponding to theslot 27 of thefixing portion 22, and a pair ofsecond lugs 35 corresponding to the pair offirst lugs 28. Thesecond lugs 35 have a pair of third threadedholes 351 corresponding to the first and second threadedholes - The
fasteners 4 are inserted through the third threadedholes 351, the second threadedholes 281, and the first threadedholes 14 to secure thecover member 3 and thefixing plate 2 to themain body 1. - When the present invention is in use, as shown in
FIG. 6 , theplungers 12 are operated in thecylinder 11. Between eachcylinder 11 and eachfixing portion 22 of thefixing plate 2, the firstair sealing ring 23 on thefixing section 221 is used to prevent the air from leakage through eachcylinder 11. Between eachlid 33 of thecover member 3 and eachfixing portion 22 of thefixing plate 2, the secondair sealing ring 24 in therecess 222 is used to prevent the air from leakage through thechamber 331. Between theair passage 311 of thecover member 3 and eachlid 33, the thirdair sealing ring 32 is used to prevent the air from leakage through theair passage 311. The operation of theplungers 12 in thecylinders 11 causes a vast vibration which may change the positions of thecylinders 11, thefixing plate 2 and thecap member 3 and result in air leakage. With the engagement of thestud 34 of eachlid 33 and theslot 27 of eachfixing portion 22, the strength of thecap member 3 and thefixing plate 2 is enhanced. When theplungers 12 are reciprocated in thecylinders 11, the air in thecylinders 11 is compressed and expanded along with the movement of theplungers 12, which generates different vibrations of the twocylinders 11. Thehandle 21 is adapted to conduct the different vibrations of thecylinders 11 at respective ends so as to stabilize the twocylinders 11. Thefasteners 4 are inserted through the third threadedholes 351, the second threadedholes 28 and the first threadedholes 14 to lock thesecond lugs 35, thefirst lugs 28, and thefixture 13 together, which increases the stability of the assembly and prevents thecylinders 11 of themain body 1, thefixing plate 2 and thecap member 3 from moving their positions caused by the different vibrations of thecylinders 11.
