The patentee Mr. Yue Zengyi has gone through a long period of research and innovation from the first generation of products to the fourth generation of products. The anti-theft bolts are divided into two categories: non-removable and detachable, including three series of bolts, screws and conventional bolts and nuts (four patented technologies). The following is a description of the detachable anti-theft screw nut:
The top of the screw head is ratcheted and can only be tightened in one direction with a semi-circular shape, or a cylindrical shape with a freely-rotatable round outer jacket (see figure). The upper half of the head of the screw is semicircular or conical, the lower half is cylindrical and the outer side is provided with a freely rotatable cylindrical outer cover, so that the current existing common tools including wrenches, pipe clamps, etc. cannot be clamped. Use force to effectively prevent others from carrying out illegal dismantling operations. When using the special transition fittings shown in the figure, a simple wrench can be used to fasten the work in one direction. When disassembled, it can be easily removed by using dedicated transition pieces and ordinary wrenches. The
The anti-theft screw consists of a cone or cylindrical screw and a cylindrical jacket. Conical bolts have concave ratchet teeth on the upper face and side concave surfaces on the lower outer circle. The upper outer half of the round outer jacket is threaded, and the outer half of the lower outer half is machined into flat or hexagonal which can be rotated by an ordinary spanner tool, and the lower inner side is made inward convex table top. The height of the table top is greater than the thickness of the table top. After the conical bolt and the outer cover are combined, the outer cover can be freely moved under any circumstances. Remove the bolts in the same way as screws. The
All parts have been carefully processed and manufactured by car, milling, boring, drilling, and rolling mills, ensuring strict quality and safety. The
Application range:
The anti-theft bolt screw is not limited in application as ordinary screw bolts, so its application is very broad, such as: electric facilities, railway facilities, highway facilities, oil field facilities, urban lighting street lighting facilities, lamp car tires and public fitness Equipment and so on. As long as it is an item fixed with bolts and screws, this technology and product can be applied to prevent unintentional disassembly, and it can be prevented from being stolen and lost, thereby strengthening the management and protection of public facilities and equipment. Excellent product performance. Received extensive attention and praise from all sectors of society. The
Anti-theft screw bolt technical parameters:
In strict accordance with the standards of national standards and various industry regulations, production and processing. The
Compared to similar products:
One, complete specifications, variety, can be repeatedly disassembled for easy maintenance. The
Second, different batches, different industries, different regions can use different disassembly methods to avoid the characteristics of interoperability. The
Third, dismantling through the special transition parts, can be repeatedly used ordinary wrench operation, without special equipment and special tools, and transitional parts lightweight and compact and practical, saving time and effort (demolition and installation time is basically the same) makes the field, high altitude and other operations and ordinary Standard parts are as simple and safe. The
The company provides a variety of models of anti-theft screws and bolt products, and can be designed and manufactured according to the specific requirements of different customers, superior product performance. We believe in: protecting the interests of our customers and creating the greatest value for our customers. We hope to become a partner you can trust to work together to create a safe and beautiful future.
