[0011] In summary, this application includes the following beneficial technical effects:

[0012] 1. By setting up a placement plate, screw multiple pins into the placement holes on the placement plate in turn, and observe whether the pins are completely immersed in clean water. The output shaft of the motor drives the support plate to rotate, the support plate drives the placement plate to rotate, and the placement plate drives the pins to rotate.

[0018] The following will be combined with the attached Figure 1-3 The technical solution of the utility model is described clearly and completely. Obviously, the described embodiments are part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] The present application embodiment discloses a pin shaft strength detection device, referring to Figure 1-3, including a detection barrel 1, a motor 2 is fixedly connected to the center of the bottom side of the detection barrel 1, a support plate 3 is fixedly connected to the output shaft of the motor 2, a placement tray 4 is fixedly connected to the center of the top side of the support plate 3, a plurality of placement holes are opened on the top side of the placement tray 4, a support column 5 is fixedly connected to the bottom side of the detection barrel 1, the detection barrel 1 is filled with clean water, and the liquid level of the clean water is five centimeters higher than the top side of the placement tray 4; by setting the placement tray 4, a plurality of pins are screwed into the placement holes on the placement tray 4 in turn, and it is observed whether the pins are completely immersed in the clean water, the output shaft of the motor 2 drives the support plate 3 to rotate, the support plate 3 drives the placement tray 4 to rotate, and the placement tray 4 drives the pins to rotate, and the friction between the pins and the water can be accelerated when the pins rotate. After waiting for forty-eight hours, the pins are observed to see if rust occurs, so that the corrosion resistance of the pins can be judged to ensure that the qualified pins will not cause safety hazards due to rust during later use, thereby avoiding accidents.

[0020] In the present application, a plurality of baffles 6 are fixedly connected to the inner wall of the detection barrel 1, and the plurality of baffles 6 are all inclined at twenty degrees; by setting the baffles 6, when the pin rotates in the water, the water will gradually rotate synchronously. At this time, the baffles 6 can be used to form an obstacle to the water to prevent the water and the pin from rotating synchronously, thereby avoiding the pin and the water being in a relatively static state during the synchronous rotation and affecting the results of the anti-corrosion test.

[0021] In the present application, a sealing cover 7 is adapted to be installed on the top side of the detection barrel 1, and a compression pump 8 is fixedly connected to the center of the top side of the sealing cover 7, and the compression pump 8 is communicated with the sealing cover 7; by setting the compression pump 8, when the pin shaft is immersed in water for anti-corrosion testing, the sealing cover 7 is used to seal the detection barrel 1. At this time, the compression pump 8 is used to change the pressure environment inside the detection barrel 1, thereby simulating the different consequences of different air pressures in different altitudes on anti-corrosion testing, thereby further improving the scientific nature of the pin shaft corrosion resistance test data.

[0022] In the present application, an annular groove is opened on the outer side of the detection barrel 1, and an annular sealing strip 9 is fixedly connected to the inner wall of the annular groove; by providing the annular sealing strip 9, when the sealing cover 7 closes the detection barrel 1, the annular sealing strip 9 fits with the inner wall of the sealing cover 7, and the sealing performance can be further improved at this time.

[0023] In the present application, a plurality of hemispheres 10 are fixedly connected to the inner wall of the bottom side of the detection barrel 1, and the plurality of hemispheres 10 are in contact with the bottom side of the support plate 3; by setting the hemispheres 10, the plurality of hemispheres 10 cooperate with each other to support the support plate 3 from the bottom side, thereby improving the stability of the support plate 3 when rotating. At the same time, the spherical design of the hemisphere 10 can reduce the contact area with the support plate 3, thereby improving the smoothness of the rotation of the support plate 3.

[0024] The standard parts used in the utility model can all be purchased from the market, and special-shaped parts can be customized according to the instructions and the drawings. The specific connection methods of each part adopt the conventional means such as mature bolts, rivets, welding, etc. in the existing technology. The machinery, parts and equipment all adopt the conventional models in the existing technology, and the circuit connection adopts the conventional connection method in the existing technology, which will not be described in detail here.

[0025] The implementation principle of a pin shaft strength detection device in an embodiment of the present application is as follows: when in use, multiple pin shafts are screwed into the placement holes on the placement plate 4 in turn, and the pin shafts are observed to see if they are completely immersed in the clean water. The output shaft of the motor 2 drives the support plate 3 to rotate, and the support plate 3 drives the placement plate 4 to rotate, and the placement plate 4 drives the pin shaft to rotate. When the pin shaft rotates, the friction between the pin shaft and the water can be accelerated. After waiting for forty-eight hours, the pin shaft is observed to see if rust occurs, so that the corrosion resistance of the pin shaft can be judged to ensure that the qualified pin shaft will not cause safety hazards due to rust during later use, thereby avoiding accidents. When the pin shaft rotates in the water, the water will gradually rotate synchronously. At this time, the baffle 6 can be used to form a barrier to the water to prevent the water and the pin shaft from rotating synchronously, thereby avoiding the synchronous rotation between the pin shaft and the water. When the pin is in motion, it is relatively static and affects the result of the corrosion resistance test. When the pin is immersed in water for corrosion resistance test, the sealing cover 7 is used to seal the test barrel 1. At this time, the compression pump 8 is used to change the pressure environment inside the test barrel 1, thereby simulating the different consequences of different air pressures in different altitudes on corrosion resistance testing, thereby further improving the scientific nature of the pin corrosion resistance test data. When the sealing cover 7 closes the test barrel 1, the annular sealing strip 9 fits with the inner wall of the sealing cover 7, and the sealing performance can be further improved at this time. The multiple hemispheres 10 cooperate with each other to support the support plate 3 from the bottom side, thereby improving the stability of the support plate 3 when it rotates. At the same time, the spherical design of the hemisphere 10 can reduce the contact area with the support plate 3, thereby improving the smoothness of the rotation of the support plate 3.
