The second screw structure 400 is designed such that, after the other end of the first connecting point 210 and the second connecting point 220 is screwed together via the first screw structure 300, the first screw structure 300 holds the second screw structure 400 securely and in a positional manner, thus establishing a firm connection between the connecting section 100 and the second connecting structure 200. This allows the lock head 22 of the anti-theft lock to be attached to the lock post 1, thereby eliminating the prior art safety risk of the lock chain slipping during riding and striking the bicycle frame or the rider. This not only saves storage space for the anti-theft lock but also prevents its loss.Furthermore, the fixed connection between the connecting section 100 and the second connecting structure 200 is made via the first screw structure 300 and the second screw structure 400, which allows for easy assembly and disassembly.
[0027] Furthermore, the first connecting section 110 has a first recess 111 for receiving the lock head 22, wherein the first screw element 100' is passed through the first recess 111 and screwed to the lock head 22. In the present embodiment, the first recess 111 is preferably designed as a hollow structure to allow the lock to be opened from the underside of the lock head 22 (as shown in Fig. 5 shown).
[0028] As in Fig. 3 and Fig. As shown in Figure 4, the second connecting section 120 further comprises a second recess 121. The first screw structure 300 includes a connecting block 310 arranged in the second recess 121 and several vertically arranged second screw elements 320, which pass through the second recess 121 and are screwed to the connecting block 310. In the present embodiment, the number of second screw elements 320 is preferably two, wherein the second screw elements 320 are preferably designed as screw bolts. By rotating the second screw elements 320 clockwise or counterclockwise, the connecting block 310 can be moved within the second recess 121. A horizontally arranged connecting axis 311 is fixedly mounted on the connecting block 310, at the two ends of which two projecting projections (312, 312') form for connection.Preferably the axial length (L1+L2) of the connecting axis 311 corresponds to the width W of the connecting block 310, wherein a space is provided between the connecting axis 311 and the connecting block 310 so that the two ends of the connecting axis 311 can interact with the two screw blocks (410, 410').
[0029] In the present embodiment, the axial length L2 of one projection 312 is greater than the axial length L1 of the other projection 312'. This structural design facilitates the locking of the two projections (312, 312') in the two connecting openings (430, 430') when the second screw element 320 is rotated relative to the connecting block 310, thereby displacing the connecting block 310 and ensuring good stability.
[0030] The two connecting openings (430, 430') are preferably provided as connecting bores that correspond to the outer shape of the connecting axis 311.
[0031] Two parallel first screw elements 100' are arranged on both sides of the two vertically arranged second screw elements 320 and are preferably arranged in a rectangular configuration. This facilitates a uniform force transmission from the first screw elements 100' and the second screw elements 320 to the second connection section 120, thereby extending the service life of the second connection section 120.
[0032] As in Fig. As shown in Figure 2, the second screw structure 400 preferably comprises screw blocks (410, 410') fixedly arranged at the opposite end of the first connection point 210 and the second connection point 220, as well as at least two third screw elements 420, each of which penetrates one of the screw blocks (410, 410') and is screwed to the other screw block (410, 410'), wherein connecting openings (430, 430') are provided on each of the two screw blocks (410, 410') through which the two projections (312, 312') are passed, so that the second screw structure (400) holds the first screw structure 300 and the second connection structure 200 in a positionally limited and fixed position, and assembly and disassembly are carried out easily.
[0033] As in Fig. As shown in Figure 3, the second connecting section 120 further features several first countersunk bores 122' for the first screw elements 100' and several second countersunk bores 122 for the second screw elements 320. The first countersunk bores 122' and the second countersunk bores 122 each communicate with the first recess 111 and the second recess 121, respectively. Several threaded bores (not shown) are provided on the lock head 22 for screwing in the first screw elements 100'. First threaded bores 313 are formed in the connecting block 310, each arranged symmetrically to the second countersunk bores 122. The second screw elements 320 penetrate the second countersunk bores 122 and are screwed into the first threaded bores 313, thus fixing the first screw assembly 300 to the second connecting section 120. The screw assembly facilitates assembly and disassembly.
[0034] In the present embodiment, the multiple first countersunk bores 122' are preferably two and arranged horizontally, and the multiple second countersunk bores 122 are preferably two and arranged vertically. The two first countersunk bores 122' are located on both lower sides of the two second countersunk bores 122, so that the second connecting section 120 absorbs the pressure from the first screw elements 100' and the second screw elements 320 evenly.
[0035] As in Fig. 5 and Fig. As shown in Figure 6, the first recess 111 and the second recess 121 are preferably arranged perpendicular or horizontally to each other, so that the anti-theft lock is suitable for various locking situations. This is achieved in Fig. 5. Closing vertically using key 30, in Fig. 6. The closing is done horizontally by means of a key 30. In the present embodiment, the first connecting section 110 is preferably designed as a cylindrical structure, the second connecting section 120 preferably as a cuboid structure, wherein the first connecting section 110 is fixedly arranged radially on the second connecting section 120.
[0036] As in Fig. As shown in Figure 2, the connecting block 310 and the second recess 121 slide together with play, allowing the two projections (312, 312') on the connecting block 310 to be quickly adjusted to the positions corresponding to the two connecting openings (430, 430'), thereby improving assembly efficiency.
[0037] As in Fig. As shown in Figure 2, the two screw blocks (410, 410') are preferably arranged symmetrically. One of the screw blocks 410 has at least two through holes 440 spaced apart from top to bottom, while the other screw block 410' has at least two second threaded holes 450, each arranged symmetrically to the through holes 440. In the present embodiment, the two connecting openings (430, 430') are each located between the two through holes 440 and the two second threaded holes 450. In the present embodiment, both the through holes 440 and the second threaded holes 450 are preferably two in number.In this arrangement, one connecting opening 430 is preferably located centrally between the two through holes 440, and the other connecting opening 430' is located centrally between the two second threaded holes 450, which facilitates a uniform force transmission at the connection points and extends the service life.
[0038] Preferably, the first connection point 210 and the second connection point 220 are each provided as an arc-shaped structure; wherein an arc cutout 123 is provided on the second connecting section 120, which is adapted to the outer shape of the first connecting point 210 and the second connecting point 220, wherein the arc cutout 123 is arranged on both sides of the second recess 121 and is connected to the second recess 121. The arc cutout 123 can thereby increase the contact area between the second connecting section 120 and the second connecting structure 200 and improve the stability of the connection between the two.
[0039] In the present embodiment, the first recess 111 and the second recess 121 are arranged perpendicular to each other. The first recess 111 is circular, the second recess 121 square. The center point of the arc cutout 123 and the center point of the first recess 111 are arranged symmetrically, meaning that the mounting position and the locking position are aligned, thus saving mounting space.
[0040] Preferably, the first connection point 210 and the second connection point 220 are rotatably connected to each other at one end via a pivot axis 230. The other end of the first connection point 210 and the second connection point 220 is designed such that, after the outer circumference of the lock pillar 1 has been enclosed by the first connection point 210 and the second connection point 220, a gap remains between the other ends. This allows lock pillars 1 with a smaller outer diameter to be accommodated, thus increasing the adaptability.
[0041] Furthermore, the first connecting section 110 has a through-hole 113 for inserting an Allen key. To turn the second screw elements 320, the Allen key must be inserted through the through-hole 113. When the locking chain 20 engages with the locking pin 112 (i.e., when the anti-theft lock is in the locked position), the locking chain 20 lies between the second screw elements 320 and the through-hole 113, thus preventing unauthorized disassembly of the anti-theft lock by a thief using an Allen key and achieving a theft-proof effect.
[0042] Preferably, the connecting section 100 and the second connecting structure 200 are made of a metal material, such as stainless steel or iron. In other embodiments, the connecting section 100 and the second connecting structure 200 can additionally be coated with plastic to prevent scratching of the unprotected outer surfaces of the connecting section 100 and the second connecting structure 200, which is beneficial to the aesthetic design of the product.
[0043] As in Fig. 7 and Fig. As shown in Figure 8, a further embodiment differs from the one described above in that the first connecting section 110 has a first recess 111 and a plug pin 112 arranged at the bottom of the first recess 111, which serves for a detachable connection with the lock head 22. The detachable connection is preferably a plug connection. In this embodiment, the fastening structure for an anti-theft lock 10 fulfills both the function of fixing the lock head 22 and the function of locking it by means of the connection with the lock head 22, thus exhibiting a high degree of versatility. The upper part of the first recess 111 has a hollow structure to allow closing from the side of the lock head 22 (as shown in Figure 8). Fig. 6 shown).
[0044] As in Fig. 1 and Fig.As shown in Figure 2, the present invention further provides an anti-theft lock comprising a lock chain 20. A lock ring 21 is movably connected to one end of the lock chain 20, through which the lock chain 20 can be passed. A lock head 22 is attached to the other end of the lock chain 20. It further comprises the fastening structure for an anti-theft lock 10 described above, which is detachably fixed to the lock head 22. In the present embodiment, the detachable fixed connection is preferably a screw connection, which allows for easy assembly and disassembly.
[0045] In the present embodiment, if the lock chain 20 is short, one end can be passed through the lock ring 21 after passing through the bicycle tire and connected to the fastening structure for an anti-theft lock 10, so that the bicycle can be locked directly.
[0046] In further embodiments, one end of the lock chain 20, when the lock chain 20 is long, can be wrapped around a fixed object (such as a power pole, railing, or iron post), then passed through the lock ring 21 and connected to the mounting structure for an anti-theft lock 10. This prevents the bicycle from being directly removed and improves theft protection.
[0047] In the present embodiment, the anti-theft lock is mounted as follows: First, the first connecting section 110 is screwed to the lock head 22 using the first screw elements 100'. Subsequently, the second connecting section 120 is firmly connected to the lock pillar 1 via the second connecting structure 200, thereby securing the anti-theft lock to the vehicle.
[0048] The foregoing represents the preferred embodiment of the present invention. It should be noted that a person skilled in the art in the relevant field may make several improvements and refinements, provided that they do not deviate from the principle of the present invention. These improvements and refinements are also considered to be within the scope of protection of the present invention.
