[0032] Please refer to Figures 1 to 3The present application provides an anti-theft bolt 100, which includes a screw rod 10 and a nut 20. The nut 20 is installed at the end of the screw rod 10. A disassembly groove 21 is provided on the nut 20. A disassembly column 22 is provided in the disassembly groove 21. A disassembly gap 23 is formed between the disassembly column 22 and the groove wall 21a of the disassembly groove 21. The shape of the disassembly groove 21 is configured as a first flower pattern, and the shape of the disassembly column 22 is configured as a second flower pattern. The first flower pattern includes a plurality of first petal bodies 211, and two adjacent first petal bodies 211 are connected by a first arc segment 212. The second flower pattern includes a plurality of second petal bodies 221, and two adjacent second petal bodies 221 are connected by a second arc segment 222. Wherein, along the radial direction of the screw rod 10, the first arc segment 212 and the second arc segment 222 are correspondingly arranged. In this way, by setting the first flower pattern and the second flower pattern on the nut 20, and utilizing the combination between the petal body and the arc segment and the correspondence between the first arc segment 212 and the second arc segment 222, the anti-theft function of the nut 20 is achieved. Not only is its structure simple, but the various combinations effectively improve the anti-theft effect of the anti-theft bolt 100, and it is safer to use.
[0033] Please continue to refer to Figure 3 , along the radial direction of the screw 10, the concave direction of the first petal body 211 is the same as the concave direction of the first arc segment 212. In this way, a first convex portion 213 is formed at the connection between the first petal body 211 and the first arc segment 212, and the first convex portion 213 protrudes toward the center of the screw 10 along the radial direction of the screw 10 to increase the degree of change of the structure at this location, thereby improving the anti-theft effect. And / or, the concave direction of the second petal body 221 is the same as the concave direction of the second arc segment 222. In this way, a second convex portion 223 is formed at the connection between the second petal body 221 and the second arc segment 222, and the second convex portion 223 protrudes toward the center of the screw 10 along the radial direction of the screw 10 to increase the degree of change of the structure at this location, thereby improving the anti-theft effect.
[0034] In one embodiment, in the radial direction of the screw 10 , the first petal bodies 211 correspond to the second petal bodies 221 one by one, and the concave direction of the first petal bodies 211 is consistent with the concave direction of the second petal bodies 221 .
[0035] Preferably, the first petal body 211 is arranged in a circular arc segment, and the second petal body 221 is arranged in a circular arc segment. Here, the circular arc segment has a simple structure and is easy to process and manufacture.
[0036] Furthermore, the center of the first petal body 211 and the center of the second petal body 221 are on a straight line.
[0037] Please refer to Figure 3, the number of the first petals 211 is configured as an odd number; and / or, the number of the second petals 221 is configured as an odd number. In this way, the odd number characteristic is utilized to further improve the anti-theft effect of the anti-theft bolt 100. Here, the number of the first petals 211 is configured as five, seven, or nine, etc., and the number of the second petals 221 is also configured as five, seven, or nine, etc.
[0038] like Figure 3 As shown, the concave direction of the first arc segment 212 is consistent with the concave direction of the second arc segment 222. For example, along the radial direction of the screw 10, the first arc segment 212 and the second arc segment 222 are both concave in the direction away from the center of the nut 20; or, along the radial direction of the screw 10, the first arc segment 212 and the second arc segment 222 are both concave in the direction close to the center of the nut 20. Of course, in other embodiments, the concave direction of the first arc segment 212 and the concave direction of the second arc segment 222 can also be set to be opposite. For example, in the radial direction of the screw 10, the first arc segment 212 is concave in the direction away from the center of the nut 20, and the second arc segment 222 is concave in the direction close to the center of the nut 20; or, in the radial direction of the screw 10, the first arc segment 212 is concave in the direction close to the center of the nut 20, and the second arc segment 222 is concave in the direction away from the center of the nut 20.
[0039] In this embodiment, along the radial direction of the screw rod 10 , the first arc segment 212 is recessed in a direction away from the center of the nut 20 ; similarly, the second arc segment 222 is also recessed in a direction away from the center of the nut 20 .
[0040] Furthermore, the first arc segment 212 is configured as a circular arc segment, and the second arc segment 222 is configured as a circular arc segment. With such a configuration, the circular arc segment has a simple structure, and its processing and production are more convenient.
[0041] Preferably, the radius of the first petal body 211 is R1, and the radius of the first arc segment 212 is R2; the radius of the second petal body 221 is R3, and the radius of the second arc segment 222 is R4; wherein R1>R2, R3>R4.
[0042] Please refer to Figures 4 to 6 The present application also provides a disassembly tool 200, which is used for disassembling the anti-theft bolt 100. The disassembly tool 200 includes a main body 201, one end of which is provided with a matching column 202, and a matching groove 203 is provided on the matching column 202. The matching column 202 is adapted to the disassembly gap 23, and the matching groove 203 is adapted to the disassembly column 22.
[0043] Further, the matching column 202 is set to a flower pattern, and the flower pattern of the matching column 202 is the same as the second flower pattern. The matching groove 203 is set to a flower pattern, and the flower pattern of the matching groove 203 is the same as the first flower pattern. Here, the structure of the matching column 202 matches and is consistent with the structure of the disassembly groove 21, and also has structures such as the first petal body 211 and the first arc segment 212. Therefore, the structure of the matching column 202 can refer to the structure of the disassembly groove 21, and therefore, it will not be repeated here. Similarly, the structure of the matching groove 203 matches and is consistent with the structure of the disassembly column 22, and also has structures such as the second petal body 221 and the second arc segment 222. Therefore, the structure of the matching groove 203 can refer to the structure of the disassembly column 22, and therefore, it will not be repeated here.
[0044] like Figure 5 As shown, a standard slot 204 is provided at one end of the main body 201 away from the mating column 202. With such a configuration, the standard slot 204 can be equipped with a desired standard bolt to achieve the disassembly and assembly of the standard bolt. That is, the disassembly and assembly tool 200 provided by the present application not only has the function of disassembling and assembling the standard bolt, but also has the function of disassembling and assembling the anti-theft bolt 100, making it more comprehensive in function and applicable to a wider range.
[0045] The present application also provides an anti-theft bolt kit, which includes the anti-theft bolt 100 in the above-mentioned embodiment and the disassembly and assembly tool 200 in the embodiment. The disassembly and assembly tool 200 is provided in conjunction with the anti-theft bolt 100. The disassembly and assembly tool 200 is used to disassemble and assemble the anti-theft bolt 100, that is, the anti-theft bolt 100 can be disassembled and installed through the disassembly and assembly tool 200.
[0046] As preferably, Figure 3 and Figure 6 As shown, a first mark 224 is provided on the disassembly column 22, and a second mark 205 is provided in the matching groove 203. The first mark 224 corresponds to and can match the second mark 205. In this way, through the mutual matching of the first mark 224 and the second mark 205, the disassembly tool 200 can quickly match the anti-theft bolt 100, thereby improving the working efficiency.
[0047] Optionally, the first identification 224 can be set as a color identification, a graphic identification, etc. Here, the color identification can be, for example, red, blue, yellow, etc. The graphic identification can be a letter or a number. Of course, the first identification 224 can also be other types of identification, as long as it can play an identification role, so it is not limited here.
[0048] In this embodiment, the first identifier 224 is set as a letter identifier. For example, the first identifier 224 is configured as letters such as A, B, and C. The specific identifier can be selected according to actual conditions.
[0049] The second identification 205 can be set as a color identification, a graphic identification, etc. Here, the color identification can be, for example, red, blue, yellow, etc. The graphic identification can be a letter or a number. Of course, the second identification 205 can also be other types of identification, as long as it can play the role of identification, so it is not limited here.
[0050] In this embodiment, the second identifier 205 is consistent with the first identifier 224 and is also configured as a letter identifier. For example, the second identifier 205 is configured as letters such as A, B, and C, and the second identifier 205 is the same as the first identifier 224.
[0051] When the disassembly tool 200 is needed to disassemble the anti-theft bolt 100, the corresponding disassembly tool 200 can be matched by the first mark 224 and the second mark 205. After the two are matched, the anti-theft bolt 100 can be disassembled by the corresponding disassembly tool 200.
[0052] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0053] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the scope of patent protection of the present application shall be subject to the attached claims.
