The through hole is communicated with the mounting groove, and after the bearing is installed, the gap on the edge of the inner ring of the bearing cover is communicated with the through hole. The tube body is connected to one end of the seat body close to the through hole. The interior of the tube body has a cavity for storing water, and the cavity is communicated with the through hole. The block is adapted to the inner hole of the bearing and is detachably connected to the bearing installed in the mounting groove, which can make the operation of the water seal test process more convenient and quick.

[0029] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0030] Reference Figure 1-3 A miniature bearing waterproof sealing detection device includes a detection device body 1 and a bearing 2. The detection device body 1 is composed of a base body 11, a tube body 12, a block 13 and a cover body 14. A mounting groove 111 and a guide groove 112 are opened inside the base body 11. The mounting groove 111 and the guide groove 112 are communicated with each other. The base body 11 and the tube body 12 are fixedly connected and communicated with each other. The bearing 2 is installed in the mounting groove 111 of the base body 11. The bearing 2 includes a bearing cover 21. The gap on the edge of the inner ring of the bearing cover 21 is communicated with the tube body 12. The cover body 14 is installed at the top of the tube body 12. A rotating mechanism 5 is provided inside the tube body 12.

[0031] The rotating mechanism 5 includes an outer transmission component 51 and an inner rotation component 52. The outer transmission component 51 includes a sleeve 511, an L rod 512, a rotating rod 513 and a spiral blade 514. The inner rotation component 52 includes a screw 521 and a pressure block 522. Through the rotating mechanism 5, under the action of the spiral blade 514 and the pressure block 522, the water in the cavity 121 produces greater fluctuations, thereby improving the test intensity, testing the waterproof performance of the bearing 2 under a relatively unstable water flow, producing a bearing 2 with high sealing performance, ensuring the subsequent use effect and waterproof performance of the bearing 2, and thus improving the practicality of the device.

[0032] The sleeve 511 is rotatably connected to the inside of the tube body 12, and two L-rods 512 are fixedly connected to the outside of the sleeve 511. One end of the two L-rods 512 is fixedly connected to a rotating rod 513, and the outside of the two rotating rods 513 is provided with spiral blades 514; when the sleeve 511 rotates, the rotating rod 513 connected thereto will be driven to rotate synchronously around the sleeve 511 through the L-rod 512. During the rotation of the rotating rod 513, the spiral blades 514 will cause the water in the cavity 121 to surge and flow back up and down, thereby improving the practicality of the device.

[0033] The screw 521 is threadedly connected to the inside of the sleeve 511, and the bottom end of the screw 521 is fixedly connected to a pressure block 522; the rotation of the sleeve 511 will cause the screw 521 to rotate inside the sleeve 511 to move up and down. When the screw 521 moves up and down, it will drive the pressure block 522 to slap the water in the cavity 121, thereby improving the practicality of the device.

[0034] The rotating mechanism 5 also includes a connecting rod 53 and a handwheel 54. The connecting rod 53 is rotatably connected to the inside of the cover body 14, and the bottom end of the connecting rod 53 extends to the inside of the tube body 12 and is fixedly connected to the top of the sleeve 511. The top of the connecting rod 53 is fixedly connected to the handwheel 54 above the cover body 14. By rotating the handwheel 54, the sleeve 511 is driven to rotate through the connecting rod 53. When the sleeve 511 rotates, the rotating rod 513 connected to it will be driven to rotate synchronously around the sleeve 511 through the L rod 512, thereby improving the practicality of the device.

[0035] The tube body 12 includes a cavity 121 and a scale 122. The cavity 121 is opened inside the tube body 12, and the scale 122 is set on the outside of the tube body 12. The tube body 12 is made of a transparent material as a whole, and the scale 122 is marked on the circumferential surface of the tube body 12, which is convenient for the staff to control the amount of water poured into the cavity 121. It is also convenient for the staff to judge whether the waterproof performance of the bearing 2 meets the standard by observing the liquid level scale 122 after the water seal test is carried out for a certain period of time, thereby improving the practicality of the device.

[0036] The block 13 includes a sealing portion 131 and a supporting portion 132. The sealing portion 131 is located in the inner ring of the bearing 2, and the supporting portion 132 is in contact with the bottom of the seat body 11. By inserting the sealing portion 131 of the block 13 into the inner hole of the bearing 2, the sealing portion 131 blocks the inner hole of the bearing 2, and the end face of the supporting portion 132 away from the sealing portion 131 is used as the supporting surface, so that the block 13, the seat body 11 and the tube body 12 are all in a state where the axis is vertical, thereby improving the practicality of the device.

[0037] A first sealing ring 3 is provided on the sealing portion 131 of the block 13, and the outer portion of the first sealing ring 3 contacts the inner ring of the bearing 2. A second sealing ring 4 is provided on the supporting portion 132 of the block 13, and the top end of the second sealing ring 4 extends to the inside of the seat body 11; by arranging the first sealing ring 3 and the second sealing ring 4, the first sealing ring 3 is located at the contact surface between the sealing portion 131 and the bearing 2, and the second sealing ring 4 is located at the contact surface between the supporting portion 132 and the seat body 11, which can reduce the probability of water flowing out from here, thereby improving the reliability of the use of the detection device body 1, thereby improving the practicality of the device.

[0038] Working principle: After the bearing 2 to be tested is installed in the mounting groove 111, the blocking portion 131 of the blocking block 13 is inserted into the inner hole of the bearing 2 so that the blocking portion 131 blocks the inner hole of the bearing 2. Then, the end surface of the supporting portion 132 away from the blocking portion 131 is used as the supporting surface, so that the blocking block 13, the seat body 11 and the tube body 12 are all in a state of vertical axis. At this time, the bearing 2 installed on the seat body 11 is also in a state of vertical axis. Then, a certain amount of water is poured into the cavity 121. The water entering the cavity 121 will enter the guide groove 112. The guide groove 112 will guide the water to fully contact the gap between the inner and outer ring edges of the bearing cover 21. Then, the hand wheel 54 is turned to drive the sleeve 511 to rotate through the connecting rod 53. When the sleeve 511 rotates, the rotating rod 513 connected to it will be driven to rotate synchronously around the sleeve 511 through the L rod 512. During the rotation of 13, the spiral blades 514 will cause the water in the cavity 121 to surge and flow back up and down. At the same time, when the sleeve 511 rotates, the screw 521 will be caused to rotate inside the sleeve 511 to move up and down. When the screw 521 moves up and down, it will drive the pressure block 522 to slap the water in the cavity 121. Under the action of the spiral blades 514 and the pressure block 522, the water in the cavity 121 will produce greater fluctuations, thereby improving the test intensity, testing the waterproof performance of the bearing 2 under a relatively unstable water flow, producing a bearing 2 with high sealing performance, and ensuring the subsequent use effect and waterproof performance of the bearing 2. After a certain period of time, it can be judged whether the waterproof performance of the bearing 2 meets the standard based on the change in the water amount in the cavity 121, thereby detecting whether water can enter the interior of the bearing 2 from the gap between the inner and outer ring edges of the bearing cover 21.

[0039] The tube body 12 is made of transparent material as a whole, and a scale 122 is marked on the circumferential surface of the tube body 12, which makes it convenient for the staff to control the amount of water poured into the cavity 121. It is also convenient for the staff to judge whether the waterproof performance of the bearing 2 meets the standard by observing the liquid level scale 122 after the water seal test has been carried out for a certain period of time.

[0040] By setting a first sealing ring 3 and a second sealing ring 4, the first sealing ring 3 is located at the contact surface between the sealing part 131 and the bearing 2, and the second sealing ring 4 is located at the contact surface between the supporting part 132 and the seat body 11, the probability of water flowing out from here can be reduced, thereby improving the reliability of the use of the detection device body 1. The tube body 12 includes a cavity 121 and a scale 122. The cavity 121 is opened inside the tube body 12, and a scale 122 is provided on the outside of the tube body 12.

[0041] The above are only preferred specific implementation methods of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and utility model concept of the present application within the technical scope disclosed in the present application, and they should be covered by the protection scope of the present application.
