Description

Technical Field

[0001] This utility model relates to the field of rope lock structure technology, and in particular to a tamper-proof structure for the outer shell of a rope lock. Background Technology

[0002] Existing rope locks generally include a housing, a lock box, a rope, a lock head, and a locking mechanism. The two ends of the rope are fixedly connected to the lock head, which is inserted into the lock box and connected to the locking mechanism. The locking mechanism is used to lock the lock head. The rope lock is unlocked and delocked by driving the bolt of the locking mechanism to move.

[0003] To prevent unlocking by damaging the outer casing of the rope lock, traditional rope locks employ anti-tampering measures including: 1. using anti-theft screws; 2. internal sealing with glue; 3. external welding (ultrasonic welding for plastic casings); 4. circuit detection, etc. Measures 1-3 are costly and unsuitable for highly electronic rope locks. Highly electronic rope locks require alkaline or lithium battery replacements, and sealing the structure would prevent such replacements. Therefore, highly intelligent electronic rope locks generally employ measure 4 more often.

[0004] However, due to the frequent collisions, shaking, and drops encountered in the use of rope locks, the conventional method of laying wires and connecting electrodes to form a detection loop, and identifying whether unauthorized disassembly has been detected by judging the continuity of the loop, has certain drawbacks. For example, multiple connecting electrodes need to be installed at multiple points on the shell and bottom cover to prevent prying or unilateral opening, which is relatively costly; the two connecting electrodes on the shell and bottom cover are connected by abutting, which can easily cause false alarms after the rope lock is subjected to collisions, shaking, and drops; and the isolation of the lock box and other mechanical structures from other electronic components on the shell is not considered, meaning there is a possibility of contact with the connecting electrodes or circuits through the lock box's socket.

[0005] Therefore, there is an urgent need for a tamper-proof outer shell structure for rope locks that can solve one or more of the above problems. Utility Model Content

[0006] To address one or more problems existing in the prior art, this utility model provides an anti-tamper structure for the outer shell of a rope lock. The technical solution adopted by this utility model to solve the above problems is: an anti-tamper structure for the outer shell of a rope lock, the outer shell of the rope lock comprising: a housing and a bottom cover, the housing being provided with a support facing the bottom cover, the support being fixedly connected to both ends of a connecting electrode, and an elastic electrode sheet being provided on one side of the support; The elastic electrode sheet includes: a first segment and a second segment, wherein the first segment is connected to the second segment via an inclined intermediate segment, the second segment is located below the connecting electrode, and there is a gap between the second segment and the connecting electrode; The screw is screwed into the bottom cover and threadedly connected to the connecting electrode. The lower end of the screw passes through the connecting electrode and abuts against or is threadedly connected to the second segment. The elastic electrode, the connecting electrode, and the screw form an electrically connected detection loop, wherein the connecting electrode and the first segment serve as signal input terminals.

[0007] In some embodiments, the edge of the housing opening is formed with a step, and the bottom cover is fastened onto the step; The step is provided with a slot, and the bottom cover is provided with a snap-fit ​​flange that matches the slot. The slot and the snap-fit ​​flange engage in a snap-fit ​​relationship.

[0008] In some embodiments, the housing is formed with a boss, the support is formed on the boss, and a mounting cavity is formed on the side of the boss away from the support for mounting the lock box assembly.

[0009] The technical advantages achieved by this utility model are as follows: By screwing the bottom cover into the screw and connecting electrodes and elastic electrode plates to form a detection circuit, the main controller of the rope lock determines whether the bottom cover has been opened by the on / off state of the detection circuit, and triggers an alarm and information upload when it is opened. Compared with the channel terminal docking detection circuit, the structure of this application is more suitable for the use scenario of rope locks, which can effectively reduce the number of false alarms and ensure the reliability of detection. By setting a step on the shell for the snap-fit ​​installation of the bottom cover, an anti-pry installation structure is formed to prevent the bottom cover from being pried open from the side away from the screw, so that the rope lock does not need to set multiple detection points, thereby saving costs.

Detailed Implementation

[0012] To make the above-mentioned objectives, features, and advantages of this utility model more readily understood, the specific embodiments of this utility model are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0013] like Figures 1-3 As shown, this utility model discloses an anti-tamper structure for the outer shell of a rope lock. The outer shell of the rope lock includes: a shell 1 and a bottom cover 2. The shell 1 is provided with a support 10 facing the bottom cover 2. The support 10 is fixedly connected to both ends of a connecting electrode 4. The connecting electrode 4 is a sheet-like design. An elastic electrode sheet 3 is provided on one side of the support 10. Combination Figure 2 As shown, the elastic electrode sheet 3 includes: a first segment 30 and a second segment 32. The first segment 30 is connected to the second segment 32 through an inclined intermediate segment 31. The second segment 32 is located on the lower side of the connecting electrode 4, and there is a gap between the second segment 32 and the connecting electrode 4. Screw 5 is screwed into the bottom cover 2 and threadedly connected to the connecting electrode 4. The lower end of screw 5 passes through the connecting electrode 4 and abuts against or is threadedly connected to the second segment 32. The elastic electrode 3, the connecting electrode 4, and the screw 5 form an electrically connected detection loop. The connecting electrode 4 and the first segment 30 serve as signal input terminals, and the detection loop is electrically connected to the main control of the rope lock. The purpose is to prevent the bottom cover 2 from being opened directly from the bottom without removing the screw 5. If it is forcibly opened, the detection loop will be disconnected. The main control detects the state change of the detection loop to determine whether the bottom cover 2 is open and executes corresponding preset actions, such as alarm and information upload.

[0014] It should be noted that after the screw 5 is screwed into the bottom cover 2, its lower end presses the second segment 32 downwards. Under the action of elasticity, the second segment 32 tends to push upwards. The effect is better when the lower end of the screw 5 is screwed into and passes through the second segment 32. Compared with traditional docking terminal designs, this structural design can effectively reduce electrode misalignment, electrode damage, and electrode detachment caused by rope lock collisions, drops, and shaking, thereby ensuring the reliability of the detection loop. The main control and detection loop settings and usage of the rope lock are existing conventional technologies, therefore, they will not be elaborated on here.

[0015] Specifically, such as Figure 2 , Figure 3As shown, the edge of the opening of the housing 1 has a step 11, and the bottom cover 2 is fastened onto the step 11. The step 11 is provided with a slot 110, and the bottom cover 2 is provided with a snap-fit ​​flange 20 that matches the slot 110. The slot 110 and the snap-fit ​​flange 20 are engaged. The purpose is to create an anti-pry structure between the bottom cover 2 and the housing 1, preventing the bottom cover 2 from being pried open from the side away from the screw 5, thereby ensuring safety.

[0016] Specifically, in combination Figure 2 As shown, the housing 1 has a boss 100, which is integrally formed with the housing 1. The support 10 is formed on the boss 100. A mounting cavity 101 is formed on the side of the boss 100 away from the support 10. The mounting cavity 101 is used to install the lock box assembly 6. The purpose is to isolate the lock box assembly 6 of the mechanical structure from the connecting electrode 4, the elastic electrode plate 3 and the screw 5 of the detection loop, so as to prevent unauthorized users from interfering with or damaging the detection loop through the holes of the mechanical structure (such as the insertion hole of the lock box assembly). At the same time, it provides a fixed and reliable installation position for the relevant components of the detection loop, ensuring that they are not easily displaced by collisions. Compared with the traditional design of placing the terminals on the edge of the housing / box or on the top of other components, this design has better stability and reliability, and less obstruction to the loading and unloading of mechanical parts.

[0017] In summary, this application uses screws screwed into the bottom cover, connecting electrodes, and elastic electrode plates to form a detection circuit. The main controller of the rope lock determines whether the bottom cover has been opened by checking the continuity of the detection circuit, and triggers an alarm and uploads information when it is opened. Compared with the channel terminal docking detection circuit, the structure of this application is more suitable for the application scenarios of rope locks, and can effectively reduce the number of false alarms and ensure the reliability of detection. By setting a step on the housing for the snap-fit ​​installation of the bottom cover, a pry-proof installation structure is formed, preventing the bottom cover from being pried open from the side away from the screws. This eliminates the need for multiple detection points on the rope lock, thereby saving costs.

[0018] The embodiments described above are merely illustrative of one or more implementations of this utility model, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
