Description

Technical Field

[0001] The utility model relates to the technical field of flanges, and more particularly to a corrosion-resistant flange for a laser printer. Background Art

[0002] Flange is a general term for flange. It usually refers to a disk-shaped metal body with several fixed holes around it for connecting other things. It is widely used in machinery because it looks strange and all it looks like is called a flange. Flanges are usually used to connect and fix the conveyor roller in laser printers to ensure that the output roller can be accurately aligned and firmly connected to ensure the normal operation of the printer and print quality.

[0003] In order to prevent the existing corrosion-resistant flanges used in laser printers from becoming corrosion-resistant, the flanges are usually plated to form an anti-corrosion coating on their surface. In this way, the flanges are protected from corrosion, but the anti-corrosion coating is prone to fall off and is easily damaged, which affects the corrosion protection of the flanges. Therefore, the corrosion resistance of the corrosion-resistant flanges is not stable enough. In view of this, we propose a corrosion-resistant flange for laser printers. Utility Model Content

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art, meet practical needs, and provide a corrosion-resistant flange for a laser printer to solve the technical problem that the corrosion resistance of the current corrosion-resistant flange for laser printers is not stable enough.

[0005] To solve the above technical problems, the present invention provides the following technical solutions: a corrosion-resistant flange for a laser printer, comprising a flange body, a T-shaped protective cover arranged on the outside of the flange body, and the T-shaped protective cover is symmetrical with the flange body axis, a sealing gasket is arranged on the rear side of the T-shaped protective cover, a sleeve ring seat is rotatably arranged on the front opening of the T-shaped protective cover, and a sealing ring is arranged on the inner wall of the sleeve ring seat;

[0006] The sleeve ring seat includes a connecting sleeve, which has four groups of screws equidistantly arranged around it. A pressure ring is installed on the front side of the connecting sleeve through the screws. The screw passes through the front end of the pressure ring and is screwed with a fastening nut. Four groups of arc-shaped clamping blocks are movably arranged equidistantly around the connecting sleeve, and the arc-shaped clamping blocks are staggered with the screws.

[0007] The utility model is designed with a T-shaped protective cover, a sleeve ring seat and a sealing ring. Therefore, when the flange body is fixedly installed on the laser printer conveying roller, a T-shaped protective cover can be installed on the outside of the flange body. The rear end of the T-shaped protective cover is sealed with the inner wall of the laser printer through a sealing gasket, and the interior of the sleeve ring seat with an opening at the front end of the T-shaped protective cover is sealed with the conveying roller of the laser printer through a sealing ring. Therefore, the overall sealing protection of the flange body can be achieved, which can effectively prevent the laser printer from being corroded by air, dust, toner or other pollutants contacting the flange body when the laser printer is working. In addition, the T-shaped protective cover has a long protection life and is not easily damaged. Therefore, the corrosion protection performance of the T-shaped protective cover for the flange body is more stable and lasting. The sleeve ring seat in the utility model is composed of a connecting sleeve ring, a screw, a fastening nut, a pressure ring and an arc-shaped pressing block. The sealing ring is located in the embedding groove of the connecting sleeve ring. Therefore, when the sleeve ring seat is sleeved on the conveying roller of the laser printer When the T-shaped protective cover is installed, the initial tightness is small, which makes it convenient for the T-shaped protective cover to slide to a suitable position on the laser printer conveyor roller for installation. After the T-shaped protective cover is fixed and installed, the personnel can drive the pressure ring to move by screwing the fixing nut. When the pressure ring moves, the stepped inclined surface of the arc-shaped pressure block will drive the arc-shaped pressure block to move into the embedded groove, so that the arc-shaped pressure block will tighten and press the sealing ring embedded in the groove inward, and when the arc-shaped pressure block is tightened and moved inward to a suitable degree, the inner wall of the pressure ring will be pressed on the horizontal arc surface of the stepped inclined surface, thereby ensuring the stability of the pressure ring pressing the arc-shaped pressure block, and it is not easy to loosen, thereby greatly increasing the strength of the sealing ring fitting on the laser printer conveyor roller. Therefore, it can effectively ensure the sealing performance of the laser printer conveyor roller passing through the sleeve ring seat, avoid the occurrence of poor sealing, and further ensure the stability of the T-shaped protective cover's anti-corrosion protection of the flange body.

[0008] Preferably, the connecting ring includes a first ring and a second ring, the first ring is rotatably arranged at the front end opening of the T-shaped protective cover, the second ring is arranged with a front side of the first ring, and the second ring is located outside the T-shaped protective cover, and the screw is arranged at the front side of the first ring.

[0009] Preferably, the first and second rings are combined in a T-shape, and the inner diameters of the first and second rings are the same, the outer diameter of the first ring is larger than the outer diameter of the second ring, and the inner diameter of the pressure ring is the same as the outer diameter of the second ring.

[0010] Preferably, an embedding groove is provided on the inner wall of the second collar, and the sealing ring is located in the embedding groove. Four groups of equidistant arc-shaped through holes are provided around the outer wall of the connecting collar. The arc-shaped clamping block is composed of an arc-shaped pressure plate and an arc-shaped protruding plate. The arc-shaped pressure plate is located inside the embedding groove, and the arc-shaped protruding plate is located in the arc-shaped through hole. The front side of the arc-shaped protruding plate passing through the arc-shaped through hole is a stepped inclined surface.

[0011] Preferably, a connecting ring is rotatably arranged inside the flange body, and two groups of symmetrical limiting grooves are formed on the inner wall of the connecting ring.

[0012] Preferably, the rear end of the connecting ring is sealed, and several groups of second bolts are arranged circumferentially on the rear side of the connecting ring, several groups of first bolts are arranged equidistantly around the flange body, and several groups of third bolts are arranged equidistantly around the T-shaped protective cover.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. The utility model is designed with a T-shaped protective cover, a sleeve ring seat and a sealing ring. Therefore, when the flange body is fixedly installed on the conveying roller of the laser printer, the T-shaped protective cover can be installed on the outside of the flange body. The rear end of the T-shaped protective cover is sealed with the inner wall of the laser printer through a sealing gasket, and the inside of the sleeve ring seat with an opening at the front end of the T-shaped protective cover is sealed with the conveying roller of the laser printer through a sealing ring. Therefore, the overall sealing protection of the flange body can be achieved, which can effectively prevent the air, dust, toner or other pollutants from contacting the flange body and causing corrosion when the laser printer is working. In addition, the T-shaped protective cover has a long protective life and is not easily damaged. Therefore, the anti-corrosion protection performance of the T-shaped protective cover for the flange body is more stable and lasting, solving the technical problem that the anti-corrosion performance of the current corrosion-resistant flange used for laser printers is not stable enough. Therefore, the utility model has the advantage of more stable anti-corrosion performance.

[0015] 2. The sleeve ring seat in the present invention is composed of a connecting sleeve ring, a screw, a fastening nut, a pressure ring and an arc-shaped pressing block. The sealing ring is located in the embedded groove of the connecting sleeve ring. Therefore, when the sleeve ring seat is sleeved on the conveying roller of the laser printer, the initial tightness is small, which facilitates the T-shaped protective cover to slide to a suitable position on the conveying roller of the laser printer for installation. After the T-shaped protective cover is fixed and installed, the personnel can drive the pressure ring to move by screwing the fixing nut. When the pressure ring moves, the stepped inclined surface of the arc-shaped pressing block cooperates to drive the arc-shaped pressing block to move into the embedded groove, thereby arc The arc-shaped pressing block will tighten and press the sealing ring embedded in the groove inward, and when the arc-shaped pressing block is tightened and moved inward to an appropriate degree, the inner wall of the pressure ring will be pressed on the horizontal arc surface of the stepped inclined surface, thereby ensuring the stability of the pressure ring pressing on the arc-shaped pressing block and not prone to loosening, thereby greatly increasing the strength of the sealing ring fitting on the laser printer conveyor roller. Therefore, it can effectively ensure the sealing performance of the laser printer conveyor roller passing through the sleeve ring seat, avoid the occurrence of poor sealing, and further ensure the stability of the T-shaped protective cover's anti-corrosion protection of the flange body.

[0028] In an embodiment of the present invention, the sleeve ring seat 3 includes a connecting sleeve 5, and the connecting sleeve 5 has four groups of screws 6 arranged equidistantly around the circle. The front side of the connecting sleeve 5 is provided with a pressure ring 7 through the screw 6. The screw 6 passes through the front end of the pressure ring 7 and is screwed with a fastening nut 601. The connecting sleeve 5 has four groups of equidistant arc-shaped pressing blocks 8 arranged movably around the circle, and the arc-shaped pressing blocks 8 are staggered with the screw 6; the connecting sleeve 5 includes a first sleeve 501 and a second sleeve 502, the first sleeve 501 is rotatably arranged at the front end opening of the T-shaped protective cover 2, the second sleeve 502 is arranged at the front side of the first sleeve 501, and the second sleeve 502 is located outside the T-shaped protective cover 2, and the screw 6 is arranged at the first sleeve The front side of the ring 501; the first ring 501 and the second ring 502 are combined in a T shape, and the inner diameters of the first ring 501 and the second ring 502 are the same, the outer diameter of the first ring 501 is larger than the outer diameter of the second ring 502, and the inner diameter of the pressure ring 7 is the same as the outer diameter of the second ring 502; the inner wall of the second ring 502 is provided with an embedding groove 503, and the sealing ring 4 is located in the embedding groove 503, and the outer wall of the connecting ring 5 is provided with four groups of equidistant arcuate through holes 504, the arc-shaped pressing block 8 is composed of an arc-shaped pressure plate 801 and an arc-shaped protruding plate 802, the arc-shaped pressure plate 801 is located inside the embedding groove 503, the arc-shaped protruding plate 802 is located in the arc-shaped through hole 504, and the arc-shaped protruding plate 802 is located in the arc-shaped through hole 504. The front side of the outlet plate 802 passing through the arc-shaped through hole 504 is a stepped inclined surface 803. When the sleeve ring seat 3 is fitted on the laser printer conveyor roller, the sealing ring 4 is located inside the embedding groove 503. Therefore, the initial tightness between the sealing ring 4 and the laser printer conveyor roller is relatively small, which facilitates the T-shaped protective cover 2 to slide to a suitable position on the laser printer conveyor roller for installation and fixation.

[0029] Working principle: This embodiment provides a corrosion-resistant flange for a laser printer. First, put the T-shaped protective cover 2 on the laser printer conveyor roller, then insert the end of the laser printer conveyor roller into the connecting ring 102, then the convex strip on the end of the laser printer conveyor roller is inserted into the limiting groove 103 to limit the position, and then screw the second bolt 104 into the end of the laser printer conveyor roller to fix it, thereby completing the connection and installation of the flange body 1 and the laser printer conveyor roller, and then fix the flange body 1 to the inner wall of the laser printer with the first bolt 101, and then slide the T-shaped protective cover 2 so that its back side is close to the inner wall of the laser printer. The T-shaped protective cover 2 is then fixed to the inner wall of the laser printer by the third bolt 202. At this time, the rear end of the T-shaped protective cover 2 is sealed with the inner wall of the laser printer via the sealing gasket 201, and the front end of the T-shaped protective cover 2 is sealed with the conveying roller of the laser printer via the sealing ring 4. Therefore, the overall sealing protection of the flange body 1 can be achieved, which can effectively prevent the air, dust, toner or other pollutants from contacting the flange body 1 and causing corrosion when the laser printer is working. In addition, the T-shaped protective cover 2 has a long protective life and is not easily damaged. Therefore, the anti-corrosion protection performance of the T-shaped protective cover 2 on the flange body 1 is more stable and lasting.

[0030] Secondly, when the sleeve ring seat 3 is fitted on the laser printer conveying roller, the sealing ring 4 is located inside the embedding groove 503. Therefore, the initial tightness of the sealing ring 4 and the laser printer conveying roller is relatively small, which facilitates the T-shaped protective cover 2 to slide to a suitable position on the laser printer conveying roller for installation and fixation. After the T-shaped protective cover 2 is fixedly installed, the personnel can drive the pressure ring 7 to move by screwing the fastening nut 601. When the pressure ring 7 moves, the arc-shaped protruding plate 802 is guided by the stepped inclined surface 803, and the arc-shaped protruding plate 802 and the arc-shaped pressure plate 801 move into the embedding groove 503, thereby the arc-shaped pressure plate 801 The sealing ring 4 embedded in the groove 503 will be tightened and pressed inward, and when the arc-shaped pressing block 8 is tightened and moved inward to an appropriate degree, the inner wall of the pressure ring 7 will be pressed on the horizontal arc surface of the stepped inclined surface 803, thereby ensuring the stability of the pressure ring 7 pressing the arc-shaped pressing block 8, and it is not easy to loosen, thereby greatly increasing the strength of the sealing ring 4 fitting on the laser printer conveyor roller. Therefore, it can effectively ensure the sealing performance of the laser printer conveyor roller passing through the sleeve ring seat 3, avoid the occurrence of poor sealing, and further ensure the stability of the corrosion protection of the flange body 1 by the T-shaped protective cover 2.
