The surfaces of the outer tube 1 and the first inner tube 2 and the second inner tube 3 of the anti-rust layer are formed with anti-rust layers.

Example 4

Take the following raw materials and weigh in parts by weight: 35 parts of epoxy resin, 15 parts of calcium carbonate powder, 18 parts of titanium dioxide powder, 18 parts of aluminum oxide powder, 20 parts of polytetrafluoroethylene, 10 parts of quartz powder, 12 parts of alcohol ester 5 parts, 5 parts of triethanolamine, 4 parts of emulsified silicone oil and 50 parts of ethanol;

S1. Add the weighed alcohol ester twelve, triethanolamine, emulsified silicone oil and ethanol into a mixer and stir for 20 minutes at a stirring speed of 600r/min to prepare a mixed solution;

S3. Add the mixed solution prepared in step S1 and the mixed powder material prepared in step S2 into the reaction kettle and stir for 40 minutes, set the stirring speed of the reaction kettle to 800r/min and the temperature to 80°C, and then filter. In this way, anti-rust paint is prepared;

S6. Put the outer tube 1 and the first inner tube 2 and the second inner tube 3 with the electrophoretic layer produced in step S5 in a drying chamber for drying and curing. The drying and curing temperature is set to 140°C, and the time is set to 40 minutes. The surfaces of the outer tube 1 and the first inner tube 2 and the second inner tube 3 of the anti-rust layer are formed with anti-rust layers.

Using a salt spray tester, the outer tube 1 and the first inner tube 2 and the second inner tube 3 in Examples 1-4 were tested for their rust resistance in the laboratory under the same conditions (tested for 24 hours). The test results The following table:

From the comparison and analysis of the test results in the above table, it can be seen that Example 3 is the best embodiment. By adopting the above technical scheme, the process steps for preparing the anti-rust coating are simple and easy to realize. The prepared anti-rust coating has moderate viscosity, is not easy to layer, and has no bubbles. , The components are fully combined, and the overall performance is good, so that the anti-corrosion coating can form a good film after electrophoresis, is not easy to produce cracks, has a good film-forming effect, and the prepared anti-rust layer has good anti-rust and resistance Abrasion, dustproof, anti-aging performance, good adhesion, not easy to fall off, can effectively increase the rust, wear, dust, and aging resistance of the outer tube 1, the first inner tube 2 and the second inner tube 3 , So that the new type of fixture has a longer service life.

Working principle: The outer tube 1, the first inner tube 2 and the second inner tube 3 form the main structure of the new fixer. The first inner tube 2 and the second inner tube 3 can be inside the outer tube 1. Telescopic adjustment, the adjustment unit 4 is used to lock the position of the first inner tube 2 inside the outer tube 1 and press the handle 11 so that the handle 11 fits outside the outer tube 1. When the spring 19 is compressed, it will be connected by the connecting sleeve 12 The sheet 17 is compressed, the connecting sheet 17 exerts pressure on the connecting seat 13, and the connecting seat 13 pushes the first inner tube 2 to the outside of the outer tube 1. At this time, the two ends of the novel fixer are respectively compressed with the fixed object. So as to realize the fixation of the fixed object.

How to use: When in use, 1) When fixing the cargo inside an ordinary truck, use a new type of fixator with a contact unit 5 composed of a fixing bolt 20 and a contact plate 21 to contact the contact plate 21 on the surface of the cargo , And then adjust the length of the second inner tube 3 inside the outer tube 1 by operating the locking member 33 until the second inner tube 3 can no longer be extended, press the handle 11 so that the handle 11 fits on the outside of the outer tube 1, the spring 19 When compressed, the connecting piece 17 will be pressed tightly by the connecting sleeve 12. The connecting piece 17 exerts pressure on the connecting seat 13, and the connecting seat 13 pushes the first inner tube 2 to the outside of the outer tube 1. At this time, the new holder The two ends of the carrier are pressed against the cargo respectively, so as to realize the fixation of the cargo, which can prevent the undesirable phenomenon of collision of the cargo during transportation, can effectively prevent damage to the cargo, and avoid economic losses to the carrier. When the cargo needs to be unloaded, lift By lifting the handle 11 and operating the locking member 33 to retract the second inner tube 3 into the outer tube 1, the new fixer can be removed to realize the release of the goods.

2) When fixing the goods inside the truck equipped with aluminum plate 31, it is necessary to use this new type of fixture with a contact unit 5 consisting of a cylindrical pin 22, an inner rod 23, a circular plate 30 and a cylindrical block 24 When fixing the cargo, the aluminum plate 31 is attached to the surface of the cargo, and then the cylindrical blocks 24 at both ends of the new holder are inserted into the cylindrical groove 32, and then the second inner part is adjusted by operating the locking piece 33 The length of the tube 3 inside the outer tube 1 until the second inner tube 3 can no longer be extended. Press the handle 11 so that the handle 11 fits the outside of the outer tube 1. When the spring 19 is compressed, the connecting piece will be connected by the connecting sleeve 12 17 is pressed tightly, the connecting piece 17 exerts pressure on the connecting seat 13, and the connecting seat 13 pushes the first inner tube 2 to the outside of the outer tube 1. At this time, the two ends of the new type fixer are respectively compressed with the cargo, thereby realizing the alignment The fixing of the cargo can prevent the undesirable phenomenon of cargo collision during transportation, can effectively prevent damage to the cargo, and avoid economic losses to the carrier. When the cargo needs to be unloaded, lift the handle 11 and operate the locking member 33 to make the first After the second inner tube 3 is retracted into the outer tube 1, the new type fixer can be removed to realize the loosening of the goods.

installation method:

Step 1. According to Figure 2, fix the limit pin 18 inside the outer tube 1, hinge one end of the connecting piece 17 to one end of the connecting sleeve 12 through the pin shaft 16, and then install the spring 19 on the connecting sleeve Inside 12, put the connecting sleeve 12 and spring 19 into the outer tube 1 together, while ensuring that the connecting piece 17 is located above the connecting sleeve 12;

The second step, one end of the connecting seat 13 is hinged to the inside of the hinge groove 15 through the pin 16, and then the end of the first inner tube 2 with the hinge groove 15 is inserted into the inside of the outer tube 1, and then the connecting seat 13 is passed through the pin The shaft 16 is hingedly connected with the other end of the connecting piece 17. At this time, the connecting seat 13 is pulled out of the installation groove 6, and the connecting seat 13 is fixedly installed on the upper end of the handle 11 with screws;

The third step is to use the limit bolt 14 to fix the first inner tube 2 inside the limit slot 7;
