Description
Technical Field
[0001] The utility model relates to the technical field of screws, in particular to a screw capable of preventing thread slipping. Background Art
[0002] Screws are a common fastener, widely used in machinery, electrical appliances and buildings. They are generally made of metal or plastic, cylindrical, and have threads on the surface. Screws have important tasks in industry. As long as there is industry on earth, the function of screws will always be important. Screws have been a common invention in people's production and life for thousands of years. In terms of application fields, it is the first invention of mankind.
[0003] Screw thread slippage often occurs during use, mainly because the threads of the screw or the screw threads of the nut are worn out. Once the screw is stripped, it is difficult to remove it, which will delay the construction period and cause a lot of manpower waste. The existing screws are usually tightened on the surface of the part directly using a wrench or screwdriver when in use, so that the nut is directly fitted with the upper surface of the part. The tightness of the screw depends entirely on the experience and feel of the staff. It is easy to cause excessive force to cause the screw threads to wear out or the screw threads of the nut to wear out, and then cause thread slippage, which is less practical. Utility Model Content

[0034] See also Figure 1-5 The utility model provides a technical solution: a screw capable of preventing thread slipping, comprising a screw flange 1, a cylinder 2 is fixedly mounted on the center of the upper surface of the screw flange 1, a hexagonal groove 3 is provided on the center of the upper surface of the cylinder 2, and rectangular grooves 4 are provided on the middle positions of the six sides of the hexagonal groove 3;
[0035] Among them, arc-shaped elastic plates 5 are fixedly installed on the left and right surfaces of the rectangular grooves 4 on the front and rear sides, and rectangular plates 6 are slidably installed inside the other four rectangular grooves 4. Hexagonal plates 7 are fixedly installed on the opposite surfaces of the four rectangular plates 6, and the hexagonal plates 7 are adapted to the inside of the hexagonal grooves 3;
[0036] A cross slot 8 is provided at the inner bottom of the hexagonal slot 3. By providing the cross slot 8, when there is no hexagonal wrench, a cross screwdriver can be used to tighten or remove the screw.

When it is necessary to screw out the screw, place the hexagonal wrench inside the hexagonal plate 7, and by setting a number of anti-skid grooves 15, the friction between the wrench and the hexagonal plate 7 is enhanced to avoid thread slippage. When the several anti-skid grooves 15 inside the hexagonal plate 7 are worn after long-term use, pull the two rings 14 to make The two fixing plates 11 move upward, and the two fixing plates 11 move upward to drive the two limiting plates 12 to move out of the rectangular grooves 4 on the front and rear sides, and at the same time drive the four rectangular plates 6 to disengage from their corresponding rectangular grooves 4, and then move the hexagonal plate 7 out of the hexagonal groove 3, and then replace or repair the worn anti-slip plate, and then slide the four rectangular plates 6 and the two limiting plates 12 into the corresponding rectangular grooves 4, and the two limiting plates 12 slide into the rectangular grooves 4 on the front and rear sides so that the two corresponding arc-shaped elastic plates 5 on the left and right are elastically deformed. When the two limiting plates 12 move to the bottom ends of the two rectangular grooves 4, the two corresponding arc-shaped elastic plates 5 on the left and right are restored to their original state and then the two limiting plates 12 are clamped in the two rectangular grooves 4, and then the hexagonal plate 7 is fixed.
