Detailed Implementation

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0037] See Figures 1-9 This utility model provides an anti-theft component 1, including a connecting base 10, a protective cover 20, a rotating member 30, and a key cover 50. The protective cover 20 is connected to the outside of the connecting base 10 and can move relative to the connecting base 10, and the protective cover 20 and the connecting base 10 enclose a receiving cavity 210. The rotating member 30 is located inside the receiving cavity 210, and the protective cover 20 protects the rotating member 30, preventing others from directly contacting the rotating member 30 with tools that are not compatible with the rotating member 30; the rotating member 30 can move relative to the connecting base 10. The key cover 50 is detachably connected to the rotating member 30, and the movement of the key cover 50 along the axial direction of the rotating member 30 can cause the rotating member 30 to contact or separate from the connecting base 10. Specifically, when the rotating member 30 contacts the connecting base 10, rotating the key cover 50 can cause the rotating member 30 and the connecting base 10 to rotate synchronously.

[0038] Bolts and nuts are commonly used locks. The anti-theft component 1 provided in this embodiment is a nut kit that passes through the nut's connecting seat 10 and connects to the bolt. A protective cover 20 is provided on the outside of the nut to protect it. The nut can only be rotated under specific conditions to form the anti-theft component 1. The anti-theft component 1 can drive the bolt to rotate.

[0039] Specifically, in use, the user places the key cover 50 onto the rotating component 30 and presses the key cover 50, causing the rotating component 30 to move towards the connecting seat 10 under pressure, ultimately bringing the rotating component 30 into contact with the connecting seat 10. At this time, pressing and rotating the key cover 50 simultaneously causes the rotating component 30 to rotate, further causing the connecting seat 10 to rotate synchronously. For example, Velcro or adhesive is provided on the opposite side of the rotating component 30 and the connecting seat 10, allowing them to move together when in contact. Alternatively, a locking structure is also provided on the opposite side of the rotating component 30 and the connecting seat 10, engaging them to ensure their coordinated movement. When the key cover 50 is removed, the rotating component 30 moves in the same direction as the key cover 50, separating it from the connecting seat 10 for easy reuse and further enhancing the anti-theft effect of the anti-theft component 1.

[0040] The rotating component 30 is, for example, the aforementioned nut. The rotating component 30 is housed within the receiving cavity 210 formed by the protective cover 20 and the connecting seat 10, preventing direct contact with the rotating component 30 and increasing anti-theft security. The protective cover 20 is rotatably connected to the connecting seat 10. If the protective cover 20 is rotated directly, it can only rotate independently and cannot rotate the connecting seat 10. Furthermore, when the key cover 50 is removed, others cannot directly contact and rotate the rotating component 30, thus achieving an anti-theft effect. Further, the outer wall of the rotating component 30 is a polygonal or irregularly shaped column. The key cover 50 has a polygonal or irregularly shaped groove that matches and engages with the outer wall of the rotating component 30. Rotating the key cover 50 can drive the rotating component 30 to rotate. If the rotating component 30 has a smooth cylindrical outer wall, the key cover 50 cannot drive the rotating component 30 to rotate.

[0041] Furthermore, the key cover 50 may be provided with a soft rubber part, which increases the friction between the key cover 50 and the rotating part 30 when the key cover 50 is engaged with the rotating part 30. The key cover 50 can better drive the rotating part 30 to move, and further ensures that the rotating part 30 and the connecting seat 10 are separated when the key cover 50 is pulled out.

[0042] See Figure 2 , Figure 4 and Figure 8 In some embodiments, the connecting seat 10 is provided with a first engaging structure 110, and the rotating member 30 is provided with a second engaging structure 310 that cooperates with the first engaging structure 110. The rotating member 30 and the connecting seat 10 can be engaged by the first engaging structure 110 and the second engaging structure 310. Engaging means preventing relative rotation between the rotating member 30 and the connecting seat 10. When the key cover 50 is closed on the rotating member 30, pressing the key cover 50 causes the rotating member 30 to move toward the connecting seat 10, and the second engaging structure 310 on the rotating member 30 engages with the first engaging structure 110 on the connecting seat 10. The connecting seat 10 and the rotating member 30 are, for example, engaged by a snap-fit ​​or a convex-concave fit.

[0043] See Figure 8Furthermore, the first engaging structure 110 includes a plurality of first protrusions 111 arranged circumferentially along the connecting seat 10, with each pair of adjacent first protrusions 111 spaced apart to form a first recess 112; the second engaging structure 310 includes a plurality of second protrusions 311 arranged circumferentially along the rotating member 30, with each pair of adjacent second protrusions 311 spaced apart to form a second recess 312; when the rotating member 30 is connected to the connecting seat 10, the plurality of first protrusions 111 can be respectively embedded in the plurality of second recesses 312, and the plurality of second protrusions 311 can be respectively embedded in the plurality of first recesses 112. The engagement of the plurality of first protrusions 111 and the plurality of second recesses 312 ensures that the connecting seat 10 and the rotating member 30 can be quickly engaged. For example, a first inclined surface is provided on one end of the first protrusion 111 near the second protrusion 311, and a second inclined surface is provided on one end of the second protrusion 311 near the first protrusion 111. The first inclined surface and the second inclined surface cooperate to allow the first protrusion 111 to be smoothly inserted into the second recess 312, and the second protrusion 311 to be smoothly inserted into the first recess 112. That is, the first engaging structure 110 and the second engaging structure 310 can be smoothly engaged.

[0044] See Figure 1 , Figure 4 and Figure 9 In some embodiments, the anti-theft component 1 includes an elastic element 40, one end of which is connected to the rotating element 30, and the other end is connected to the connecting seat 10, to provide the rotating element 30 with an elastic restoring force. When the rotating element 30 is not pressed, it is separated from the connecting seat 10, requiring the user to apply pressure to engage the rotating element 30 with the connecting seat 10 before the connecting seat 10 can be turned, ensuring the anti-theft effect of the anti-theft component 1. When someone uses a device incompatible with the rotating element 30 to engage it, the simultaneous application of rotational force and downward pressure can easily lead to slippage, further enhancing the anti-theft effect. After pressing, the elastic element 40 drives the rotating element 30 to separate from the connecting seat 10 for convenient next use.

[0045] See Figure 4 , Figure 8 and Figure 9 In some embodiments, the connecting seat 10 includes a base 120 and a column 130 protruding from the surface of the base 120. The column 130 is located at one end of the base 120 near the rotating member 30 and is located inside the accommodating cavity 210. The rotating member 30 is sleeved on the outside of the column 130 and can rotate relative to the column 130. Along the axial direction of the column 130, the base 120 and the rotating member 30 are spaced apart, so that the rotating member 30 needs to be pressed to connect the rotating member 30 with the base 120 and rotate together.

[0046] See Figure 4 and Figure 8In some embodiments, the elastic element 40 includes a spring, and the rotating element 30 has a first through hole 320; the radial dimension of the first through hole 320 is larger than the radial dimension of the column 130, and the spring is located inside the first through hole 320 and sleeved on the outside of the column 130; and / or, a limiting part 330 is provided inside the first through hole 320, and the spring is located inside the first through hole 320, with one end of the spring abutting against the limiting part 330 and the other end of the spring abutting against the base 120. When the key cover 50 is removed, the elastic force of the elastic element 40 causes the rotating element 30 to automatically reset, thus creating a gap between the rotating element 30 and the connecting seat 10.

[0047] The column 130 provides a guide path for the rotating component 30, ensuring that the rotating component 30 moves axially within the column 130 and preventing it from deviating from its direction of movement when pressed, thus preventing the rotating component 30 from driving the connecting seat 10 to rotate synchronously. The spring is disposed within the first through hole 320 and sleeved on the outside of the column 130, ensuring that the spring will not deform when the rotating component 30 is pressed.

[0048] See Figure 4 , Figure 8 and Figure 9 In some embodiments, a limiting member 131 is provided at the end of the rotating member 30 away from the base 120, and covers the first through hole 320. The limiting member 131 is located at the end of the rotating member 30 away from the base 120. In one embodiment, the outline dimension of the limiting member 131 is larger than the radial dimension of the first through hole 320, and the limiting member 131 covers the first through hole 320 and is located outside the first through hole 320. In another embodiment, two limiting portions 330 are provided inside the first through hole 320 and are arranged radially opposite to each other. The outline dimension of the limiting member 131 is less than or equal to the radial dimension of the first through hole 320, and the limiting member 131 is located inside the first through hole 320. The outline dimension of the limiting member 131 is larger than the distance between the two limiting portions 330, and the limiting member 131 is located above the two limiting portions 330. This ensures that the rotating component 30 is located between the limiting component 131 and the connecting seat 10, restricting the movement range of the rotating component 30 and preventing the rotating component 30 from accidentally moving or falling out of the receiving cavity 210, thus enhancing the reliability and stability of the anti-theft component 1. The limiting component 131 is, for example, sleeved on the outside of the nut, and the nut is fixedly connected to the column 130 to fix the position of the rotating component 30 and the elastic component 40. The first through hole 320 makes it easy to install the rotating component 30 and the elastic component 40. The limiting component 131 is, for example, sleeved on the outside of the nut, and the outline dimension of the limiting component 131 is larger than the radial dimension of the first through hole 320, so as to completely cover the first through hole 320 and prevent the rotating component 30 from accidentally moving or falling out of the receiving cavity 210. In another embodiment, the limiting component 131 can be integrally formed with the nut.

[0049] See Figure 1 and Figure 2 In some embodiments, the rotating member 30 is provided with a third engaging structure 610, and the key cover 50 is provided with a fourth engaging structure 620 that cooperates with the third engaging structure 610. The rotating member 30 and the key cover 50 can be engaged by the third engaging structure 610 and the fourth engaging structure 620. The engagement is to prevent relative rotation between the key cover 50 and the rotating member 30, allowing the key cover 50 to drive the rotating member 30. When the key cover 50 is placed on the rotating member 30, the third engaging structure 610 and the fourth engaging structure 620 engage, allowing the key cover 50 to modify the movement of the rotating member 30. Furthermore, when the key cover 50 is pulled out, when the key cover 50 and the rotating member 30 reach the limiting member 131, the limiting member 131 will block further movement of the rotating member 30, thereby triggering the key cover 50 and the rotating member 30 to end the engagement. The key cover 50 and the rotating member 30 may have a concave-convex fit, for example.

[0050] See Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 In some embodiments, one of the third engaging structure 610 and the fourth engaging structure 620 includes a polygonal or irregularly shaped columnar portion 611, and the other includes an unlocking groove 621 that matches the shape of the columnar portion 611, for example, the columnar portion 611 and the unlocking groove 621 have the same shape; the columnar portion 611 can be embedded in the unlocking groove 621. The non-standard shaped columnar portion 611 makes it difficult for thieves to operate with common tools, thereby improving the anti-theft factor; the cooperation between the columnar portion 611 and the unlocking groove 621 ensures a precise fit between the key cover 50 and the rotating member 30. In other embodiments, the third engaging structure 610 and the fourth engaging structure 620 can be mutually cooperating buckle structures, which are not limited to this.

[0051] See Figures 2 to 7 The key cover 50 includes an outer shell 560 and a boss 530. The outer shell 560 is the actuating part for the user to operate the key cover 50, and the boss 530 is used to operate the rotating member 30 to rotate and unlock the connecting seat 10. One end of the boss 530 is connected to the outer shell 560, and the other end is provided with a relief groove 570 to avoid the rotating member 30.

[0052] See Figure 5 , Figure 6 and Figure 7In some embodiments, the inner sidewall of the protective cover 20 and the rotating member 30 are spaced apart to form a first slot 211, and the boss 530 can be embedded in the first slot 211. The columnar portion 611 is provided on the outer sidewall of the rotating member 30, and the clearance groove 570 is the unlocking groove 621. The key cover 50 can be embedded in the first slot 211 and is detachably connected to the rotating member 30. Specifically, one end of the outer shell 560 of the key cover 50 is provided with a first opening 510, and a receiving cavity 520 is formed inside the outer shell 560. The first opening 510 communicates with the receiving cavity 520. The boss 530 is provided at the end of the outer shell 560 opposite to the first opening 510. The boss 530 is located in the receiving cavity 520, and the boss 530 is recessed to form a clearance groove 570. In this embodiment, the clearance groove 570 is also the unlocking groove 621. The columnar portion 611 is formed by the sidewall of the rotating member 30. When the key cover 50 needs to drive the rotating component 30 to rotate together, the rotating component 30 enters the unlocking groove 621 from the first opening 510. The key cover 50 and the rotating component 30 are matched and engaged through the cooperation between the columnar part 611 and the unlocking groove 621, so that the key cover 50 can drive the rotating component 30 to rotate synchronously.

[0053] See Figure 2 , Figure 3 and Figure 4 In some embodiments, the key cover 50 includes an outer shell 560 and a boss 530. The outer shell 560 is used for the user to operate the key cover 50, and the boss 530 is used to operate the rotating member 30 to rotate, thereby unlocking the rotation of the connecting seat 10. One end of the boss 530 is connected to the outer shell 560, and the other end is provided with a relief groove 570 to avoid the rotating member 30. The rotating member 30 has a first slot 211 on the side away from the connecting seat 10, and the boss 530 can be embedded in the first slot 211; a columnar part 611 is provided on the outer wall of the boss 530, and the first slot 211 is an unlocking groove 621. The key cover 50 has a first opening 510 at its first end, and a receiving cavity 520 is formed inside the key cover 50. The first opening 510 communicates with the receiving cavity 520. A boss 530 is provided at the end of the key cover 50 opposite to the first opening 510. The boss 530 is located inside the receiving cavity 520, and a columnar portion 611 is formed by the side wall of the boss 530. When the key cover 50 needs to drive the rotating member 30 to rotate together, the key cover 50 is placed on the rotating member 30, and the boss 530 is embedded in the first slot 211. In this embodiment, the first slot 211 is also the unlocking slot 621. The key cover 50 and the rotating member 30 are matched and engaged through the cooperation of the columnar portion 611 and the unlocking slot 621, so that the key cover 50 can drive the rotating member 30 to rotate synchronously.

[0054] Furthermore, a placement groove 540 matching the protective cover 20 is formed between the boss 530 and the side wall of the key cover 50. When the key cover 50 is placed on the rotating member 30, the protective cover 20 enters the key cover 50 through the first opening 510 and is embedded in the placement groove 540.

[0055] See Figure 5 and Figure 6 In some embodiments, a plurality of anti-slip portions 550 are provided on the outer peripheral sidewall of the key cover 50 housing 560, extending along the height of the housing 560. The anti-slip portions 550 increase the coefficient of friction of the key cover 50 sidewall, ensuring a more stable grip or operation of the key cover 50 by the user, preventing accidental drop or operational errors due to slippage, and allowing for more precise control of the rotating component 30 when operating the key cover 50. The anti-slip portions 550 are, for example, strip-shaped, circular, or square raised structures, and the material of the raised structures is, for example, rubber or silicone.

[0056] In some embodiments, see Figure 1 and Figure 2 The outer shell 560 of the key cover 50 is formed into a polygonal column or an irregular shape, making it convenient for users to hold or operate the key cover 50.

[0057] See Figure 7 In some embodiments, a first snap-fit ​​member 710 is also included. The outer side wall of the connecting seat 10 is provided with a first groove 140, and the inner side wall of the protective cover 20 is provided with a second groove 220. The first snap-fit ​​member 710 is embedded in the first groove 140 and the second groove 220. The first snap-fit ​​member 710 can stably connect the connecting seat 10 and the protective cover 20, and when the protective cover 20 is rotated, the protective cover 20 rotates relative to the connecting seat 10 without causing the connecting seat 10 to rotate together.

[0058] In some embodiments, the first snap-fit ​​member 710 is made of an elastic material. The first snap-fit ​​member 710 may include, for example, a snap-fit ​​structure, or be made of silicone material, etc.

[0059] See Figure 4In some embodiments, the outer side wall of the connecting seat 10 is provided with a first groove 140, and the inner side wall of the protective cover 20 is provided with a third protrusion 230 that mates with the first groove 140; the third protrusion 230 engages with the first groove 140, thereby fixing the protective cover 20 onto the connecting seat 10. Furthermore, the anti-theft component 1 also includes a second latching member 720, a portion of which covers the connecting seat 10, and another portion covers the third protrusion 230. For example, the first groove 140 penetrates the bottom surface of the connecting seat 10, facilitating the installation of the third protrusion 230 into the first groove 140. The second latching member 720 partially covers the connecting seat 10 and partially covers the third protrusion 230 to fix the protective cover 20 to the connecting seat 10, making the protective cover 20 and the connecting seat 10 rotatably connected. Even if someone moves the rotating member 30, they can only make the rotating member 30 rotate on its own, and cannot make the connecting seat 10 rotate, increasing the difficulty of rotating the connecting seat 10 and improving the anti-theft factor. The second latching member 720 is located at the end of the connecting seat 10 opposite to the rotating member 30, and the second latching member 720 is connected to the protective cover 20. The end of the connecting seat 10 opposite to the rotating member 30 is provided with a third groove 150, and the second latching member 720 has a protrusion 721 protruding from it, which is located in the third groove 150. The protrusion 721 cooperates with the third groove 150 to fix the second latching member 720 to the connecting seat 10.

[0060] Another embodiment of this utility model provides an anti-theft clip for fixing a car phone holder, so that the car phone holder can be fixedly installed on a bicycle, motorcycle, etc. The anti-theft clip can be clamped on the frame of the bicycle, motorcycle, etc., and serves as a bracket fixing device for the car phone holder, playing a role in stable support.

[0061] Specifically, see Figure 10 , Figure 11 and Figure 12 The aforementioned anti-theft clip includes the aforementioned anti-theft component 1, a screw 80, a first clamping body 910, and a second clamping body 920. One end of the screw 80 is fixedly connected to the connecting seat 10 of the anti-theft component 1. The screw 80 has a first threaded section 810 and a second threaded section 820 with opposite directions of rotation along its axial direction. The first clamping body 910 is connected to the first threaded section 810, and the second clamping body 920 is connected to the second threaded section 820. When the screw 80 rotates, it drives the first clamping body 910 and the second clamping body 920 to move towards or away from each other.

[0062] In use, the user first places the key cover 50 on the rotating part 30 and engages it. Then, the user presses the key cover 50 and the rotating part 30 to engage the rotating part 30 with the connecting seat 10. The user then rotates the key cover 50 while pressing, causing the rotating part 30 and the connecting seat 10 to rotate, which in turn rotates the screw 80. Since the screw 80 has a first threaded section 810 and a second threaded section 820 with opposite directions of rotation, rotating the key cover 50 can adjust the distance between the first clamp 910 and the second clamp 920. When the anti-theft clip needs to be attached to a bicycle or motorcycle bracket, rotating the key cover 50 causes the first clamp 910 and the second clamp 920 to move in opposite directions, opening them. Then, the user installs the first clamp 910 and the second clamp 920 on the vehicle bracket or other desired location, rotating the key cover 50 causes the first clamp 910 and the second clamp 920 to move in opposite directions, clamping and securing the bracket.

[0063] The screw 80 is provided with a first threaded section 810 and a second threaded section 820 with opposite directions of rotation, which ensures that the first clamping body 910 and the second clamping body 920 can move in opposite directions at the same time, that is, the first clamping body 910 and the second clamping body 920 can move relatively far apart or relatively close together, thereby improving the efficiency and accuracy of operation.

[0064] Furthermore, the first clamping body 910 has a first clamping end 911, and the second clamping body 920 has a second clamping end 921. When the screw 80 rotates, the screw 80 drives the first clamping end 911 and the second clamping end 921 to move in opposite directions or towards each other. The surfaces of the first clamping end 911 and the second clamping end 921 that are opposite to each other are provided with anti-slip strips, for example, to increase the friction between the anti-theft clamp and the bracket, prevent the anti-theft clamp from slipping off, and improve the stability of clamping.

[0065] In summary, in this embodiment, during use, the user first places the key cover 50 on the rotating member 30, causing the unlocking groove 621 of the key cover 50 to engage with the rotating member 30; then, pressing the key cover 50 causes the rotating member 30 to move towards the connecting seat 10, causing the second engaging structure 310 on the rotating member 30 to engage with the first engaging structure 110 on the connecting seat 10; the user presses and rotates the key cover 50 simultaneously, causing the rotating member 30 and the connecting seat 10 to rotate together, thereby rotating the screw 80. This ensures that the connecting seat 10 can only rotate when the key cover 50 is used, thus guaranteeing the anti-theft performance of the device.

[0066] When the anti-theft clip needs to be attached to the bracket of a bicycle or motorcycle, the key cover 50 is turned to make the first clip 910 and the second clip 920 move in opposite directions to open the first clip 910 and the second clip 920; then the first clip 910 and the second clip 920 are installed on the bracket, and the key cover 50 is turned to make the first clip 910 and the second clip 920 move in opposite directions to clamp the bracket and fix it.
