Description

Technical Field

[0001] This utility model relates to the field of hardware technology, specifically to a refrigerator door hinge connection device. Background Technology

[0002] Non-destructive testing (NDT) is an indispensable and effective tool for industrial development, reflecting a country's industrial development level to a certain extent. Its importance is widely recognized. Commonly used NDT methods include eddy current testing (ECT), radiographic testing (RT), ultrasonic testing (UT), magnetic particle testing (MT), and liquid penetrant testing (PT). Other NDT methods include acoustic emission testing (AE), thermal imaging / infrared testing (TIR), leak testing (LT), alternating current field measurement technology (ACFMT), magnetic flux leakage testing (MFL), far-field testing (RFT), and time-of-flight ultrasonic diffraction (TOFD).

[0003] Currently, non-destructive testing of components can be performed using industrial X-ray machines. During the use of industrial X-ray machines, shielding doors are usually installed to reduce radiation. The shielding doors are usually connected to the X-ray machine by hinges. During use, the hinge connection of the shielding door will experience some wear. Since the shielding door itself has a certain weight, continuous use can easily cause the hinges to wear, resulting in abnormal noise when the shielding door is opened and closed, affecting the service life of the shielding door. In addition, when lubricating the shielding door, it is not easy to evenly apply the grease to the hinge connection of the shielding door.

[0004] A refrigerator door hinge connection device is proposed to solve the problems mentioned above. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: a refrigerator door hinge connection device, including a mounting base plate;

[0007] Two sets of mounting holes are provided through one side of the front of the mounting substrate;

[0008] Also includes:

[0010] The lubrication assembly includes a mounting bracket fixedly installed on one side of the support frame, and a cylinder is fixedly installed on the side of the mounting bracket away from the support frame. A connecting pipe is connected through one side of the cylinder, and a lubrication groove is provided inside the support frame and the pin.

[0011] The pin is located inside the lubrication groove and has symmetrical lubrication holes on both sides. The connecting pipe is connected to the lubrication groove, and the top side of the cylinder is connected to the adding pipe.

[0012] Preferably, a movable rod is slidably connected to one side of the inner side of the cylinder, and a piston is fixedly installed at one end of the movable rod, and the piston is slidably connected to the cylinder.

[0013] Preferably, a telescopic spring is sleeved on the outer side of the movable rod, one end of the telescopic spring is fixedly connected to the cylinder, and a push block is fixedly installed on the other end of the telescopic spring, and the push block is fixedly connected to the movable rod.

[0014] Preferably, the top of the adding tube is provided with an end cap, and a sealing plug is fixedly installed at the bottom of the end cap. A rotating rod is rotatably connected to the top of the cylinder on one side of the adding tube, and a limiting frame is slidably connected to the outside of the rotating rod, with the limiting frame abutting against the end cap.

[0015] Preferably, a return spring is sleeved on the outside of the rotating rod above the limiting frame, and one end of the return spring is fixedly connected to the limiting frame, while the other end of the return spring is fixedly installed with an mounting block, which is fixedly connected to the rotating rod.

[0016] Preferably, a positioning block is fixedly installed on one side of the bottom of the limiting frame, and a positioning groove is opened on one side of the top of the end cover, with the bottom end of the positioning block abutting against the positioning groove.

[0017] Preferably, both the adding pipe and the connecting pipe are provided with a one-way valve on one side of their interior.

[0018] Compared with the prior art, the beneficial effects of this utility model are: this refrigerator-style door hinge connection device facilitates lubrication between the pin and the shielding door after a period of use on the X-ray machine's shielding door, reducing wear on the shielding door and ensuring uniform lubrication, thus improving convenience and practicality. The specific details are as follows:

[0019] 1. The shielding door on the X-ray machine can rotate on a pivot. The door, hinged to the pivot, opens and closes similarly to a water tank door. When closed, the door conceals the pivot, improving aesthetics. For lubrication, the door can be opened to expose the support frame, allowing grease to be added to the inlet tube. Pushing the push block moves the movable rod and compresses the telescopic spring, causing the piston to slide within the cylinder. Releasing the push block returns the piston to its original position under the spring's action, allowing it to reciprocate within the cylinder. A vent hole is located on the right side of the cylinder, near the movable rod, to prevent the piston from being difficult to move. When the piston moves to the right within the cylinder, a one-way valve inside the inlet tube opens, while a one-way valve inside the connecting tube closes, allowing... The grease can be drawn into the cylinder. When the piston moves to the left in the cylinder, the one-way valve inside the adding tube closes, and the one-way valve inside the connecting tube opens, allowing the grease to be pushed into the connecting tube. Through the continuous movement of the piston, the grease can enter the lubrication groove. Then the grease can leak out through two lubrication holes, allowing the grease to be evenly applied to the outside of the pin. The shielding door is fitted onto the pin and hinged to it. The grease can be applied between the pin and the shielding door. Then the operator controls the shielding door to rotate back and forth, so that the grease on the outside of the pin can be evenly distributed. After the shielding door on the X-ray machine has been used for a period of time, it is easy to lubricate the pin and the shielding door, reduce the wear of the shielding door, and ensure the uniformity of lubrication, thus improving convenience and practicality.

[0020] 2. Before lubrication, the operator pushes the limiting bracket upwards to disengage the positioning block from the positioning groove, allowing the return spring to be compressed. Then, the rotating rod is rotated so that the limiting bracket no longer obstructs the end cap, allowing the end cap and sealing plug to be removed. Lubricant can then be added. After lubrication, the end cap and sealing plug are placed on the adding tube. The limiting bracket is then moved upwards to compress the return spring. The rotating rod is then rotated to align the positioning block on the limiting bracket with the positioning groove on the end cap. At this point, the limiting bracket can be released, and the positioning block abuts against the positioning groove under the action of the return spring, positioning the end cap and sealing the adding tube. This prevents dust from entering the adding tube when lubrication is not being performed, keeping the adding tube clean and preventing dust from entering the lubrication tank.

The pin 102 is located inside the lubrication groove 204 and has symmetrical lubrication holes 205 on both sides. The connecting pipe 203 is connected to the lubrication groove 204 through. The top side of the cylinder 202 is connected to the adding pipe 206 through. This allows the grease on the outside of the pin 102 to be evenly distributed. After the shielding door on the X-ray machine has been used for a period of time, it is convenient to lubricate the pin 102 and the shielding door, reduce the wear of the shielding door, and ensure the uniformity of lubrication, thus improving convenience and practicality.

[0029] A movable rod 207 is slidably connected to one side of the inner side of the cylinder 202, and a piston 208 is fixedly installed at one end of the movable rod 207. The piston 208 is slidably connected to the cylinder 202 to facilitate the pushing of grease. A telescopic spring 209 is sleeved on the outer side of the movable rod 207, and one end of the telescopic spring 209 is fixedly connected to the cylinder 202. A push block 210 is fixedly installed at the other end of the telescopic spring 209, and the push block 210 is fixedly connected to the movable rod 207 so that the movable rod 207 can automatically return to its original position after movement. An end cap 211 is provided on the top of the adding tube 206, and a sealing plug 212 is fixedly installed at the bottom of the end cap 211. A rotating rod 213 is rotatably connected to the top of the cylinder 202 on one side of the adding tube 206, and the outer side of the rotating rod 213 is slidably connected to a limit switch. The frame 214 is abutted against the end cover 211, which can limit the end cover 211. A return spring 215 is sleeved on the outside of the rotating rod 213 above the limit frame 214. One end of the return spring 215 is fixedly connected to the limit frame 214, and the other end of the return spring 215 is fixedly installed with an installation block 216. The installation block 216 is fixedly connected to the rotating rod 213, so that the limit frame 214 can automatically return after moving. A positioning block 217 is fixedly installed on one side of the bottom of the limit frame 214, and a positioning groove is opened on one side of the top of the end cover 211. The bottom end of the positioning block 217 abuts against the positioning groove, which can position the end cover 211. One-way valves are provided on one side of the inside of the adding tube 206 and the connecting tube 203 to facilitate the grease to be pushed into the lubrication groove 204.

[0030] Working principle: Before using this type of refrigerator door hinge connection device, it is necessary to check the overall condition of the device to ensure that it can work normally. Figure 1 - Figure 5As shown, the shielding door on the X-ray machine can rotate on the pin 102. The shielding door is hinged to the pin 102 and its opening and closing mechanism is similar to that of a water tank door. After the shielding door is closed, it can cover the connected pin 102, thus concealing it and improving its aesthetics. When lubricating the pin 102, the shielding door can be opened to expose the support frame 101. Then, grease can be added to the adding tube 206. Afterward, the push block 210 can be pushed to move the movable rod 207 and compress the telescopic spring 209, causing the piston 208 to slide in the cylinder 202. After releasing the push block 210, the piston 208 returns to its original position under the action of the telescopic spring 209, allowing the piston 208 to reciprocate inside the cylinder 202. An exhaust hole is provided on the right side of the cylinder 202, on the side of the movable rod 207, to prevent the piston 208 from being difficult to move. When the piston 208 moves to the right in the cylinder 202, the one-way valve inside the adding tube 206 opens, connecting the tube 206 to the cylinder 202. 03 The internal one-way valve closes, allowing grease to be drawn into the cylinder 202. When the piston 208 moves to the left in the cylinder 202, the internal one-way valve of the adding pipe 206 closes, and the internal one-way valve of the connecting pipe 203 opens, allowing grease to be pushed into the connecting pipe 203. Through the continuous movement of the piston 208, the grease can enter the lubrication groove 204. Then, the grease can leak out through the two lubrication holes 205, allowing the grease to be evenly applied to the outside of the pin 102. The shielding door is fitted onto the pin 102 and hinged to it. The grease can be applied between the pin 102 and the shielding door. Then, the operator controls the shielding door to rotate back and forth, so that the grease on the outside of the pin 102 can be evenly distributed. After the shielding door on the X-ray machine has been used for a period of time, it is convenient to lubricate the pin 102 and the shielding door, reducing the wear of the shielding door and ensuring the uniformity of lubrication, thus improving convenience and practicality.

[0031] Before lubrication, the operator pushes the limiting frame 214 upwards to disengage the positioning block 217 from the positioning groove, allowing the return spring 215 to be compressed. Then, the rotating rod 213 is rotated so that the limiting frame 214 no longer obstructs the end cover 211, allowing the end cover 211 and sealing plug 212 to be removed. Lubricant can then be added. After lubrication, the end cover 211 and sealing plug 212 are placed on the adding tube 206. The limiting frame 214 is then moved upwards to compress the return spring 215. The rotating rod 213 is then rotated to align the positioning block 217 on the limiting frame 214 with the positioning groove on the end cover 211. At this point, the limiting frame 214 can be released, and the positioning block 217 abuts against the positioning groove under the action of the return spring 215, positioning the end cover 211 and sealing the adding tube 206. This prevents dust from entering the adding tube 206 when lubrication is not being performed, keeping the adding tube 206 clean and preventing dust from entering the lubrication groove 204.

[0032] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
