Description

Technical Field

[0001] This utility model relates to the field of electrical junction box technology, and in particular to an electrical junction box with anti-tamper alarm function. Background Technology

[0002] Electrical junction boxes are key devices in power systems used for centralized connection, distribution, and protection of wires and cables. Due to their small size and ease of installation, they are often installed on walls or other fixed locations. Because electrical junction boxes contain core conductive components, such as copper wires and terminals—high-value materials (copper has a recycling price of 60-80 yuan / kg)—theft of electrical junction boxes is frequent.

[0003] In the existing technology, in order to solve the problem of frequent theft of high-value materials in electrical junction boxes, anti-theft devices are usually installed on the door of the electrical junction box. When the thief triggers the anti-theft device, an alarm mechanism or physical locking function is activated, thereby effectively deterring theft and promptly blocking illegal operations.

[0004] However, in practical applications, it has been found that while installing anti-theft devices on the door can effectively prevent pry-open thefts, such protective measures are ineffective against thefts committed by completely disassembling the electrical junction box, as they do not cover the entire box. Therefore, an electrical junction box with anti-tamper alarm function is proposed, which can effectively prevent pry-open thefts as well as thefts committed by disassembling the entire box. Utility Model Content

[0005] The purpose of this utility model is to provide an electrical junction box with anti-tamper alarm function to solve the problems mentioned in the background art.

[0006] The technical solution adopted in this utility model is:

[0007] Electrical junction boxes with tamper-proof alarm functions include:

[0008] The main body of the box can be fixed on the mounting surface. The main body of the box has a cavity inside. The main body of the box is equipped with an anti-theft security door, an audible and visual alarm and a triggering mechanism. The audible and visual alarm is connected to a power supply.

[0009] The triggering mechanism includes:

[0010] A support frame is provided on an outer side wall of the main body of the box. Its interior is a hollow structure. A first spring is provided on an inner side wall of the support frame. A pressing plate is provided at one end of the first spring.

[0011] A micro switch is located on the other inner side wall of the support frame, corresponding to the position of the pressing plate;

One end of the guide rod protrudes from the outer wall of the support frame and can abut against the mounting surface. The other end can slide through the support frame and the micro switch in sequence and is connected to the pressing plate.

[0013] in,

[0014] When the main body of the box is fixed to the mounting surface, the guide rod is squeezed by the mounting surface, causing the micro switch to cut off the power to the audible and visual alarm; when the main body of the box is detached from the mounting surface, the squeezing force on the guide rod disappears, causing the micro switch to conduct the circuit and activate the audible and visual alarm.

[0015] Optionally, the micro switch includes:

[0016] The support part is fixedly installed on an inner side wall of the support frame and is slidably connected to the guide rod.

[0017] The pressing part is slidably disposed on the support part and opposite to the pressing plate.

[0018] Optionally, it also includes a mounting mechanism, through which the box body is fixed to the mounting surface.

[0019] Optionally, the mounting mechanism includes:

[0020] Mounting brackets are symmetrically arranged on the mounting surface, and each set of mounting brackets has at least one snap-fit ​​groove on the opposite sidewall.

[0021] A snap-fit ​​assembly is provided on the main body of the box, the number of which corresponds to the snap-fit ​​slots, and the snap-fit ​​assembly cooperates with the snap-fit ​​slots.

[0022] Optionally, the mounting bracket is detachably mounted on the mounting surface.

[0023] Optionally, the snap-fit ​​component includes:

[0024] The shells are symmetrically arranged on the main body of the box, and a sliding groove is provided on one side wall of each set of shells;

[0026] A second spring is provided inside each set of housings, with its two ends respectively abutting against the inner wall of the housing and the inner end of the locking block;

[0027] Disassemble the pull rope, which spans across the two sets of housings. Its two ends pass through the housing and the second spring in sequence and are then connected to the corresponding locking block.

[0028] Optionally, the outer end of the card block has a tapered structure.

[0029] Optionally, the card block is made of 40Cr steel.

[0030] Optionally, the audible and visual alarm is a ZWIN-ESA1006 audible and visual alarm or a TH-K-SF08 high-brightness LED audible and visual alarm.

[0031] Compared with the prior art, the beneficial effects of this utility model are:

[0032] In this invention, by incorporating a security door, an audible and visual alarm, and a triggering mechanism on the main body of the enclosure, both pry-open theft and theft of the entire enclosure by disassembly are effectively prevented. Specifically, the security door effectively prevents pry-open theft; the audible and visual alarm and the triggering mechanism work together to effectively prevent theft by disassembling the entire enclosure. When the enclosure is fixed to the mounting surface, the triggering mechanism is pressed against the mounting surface and cuts off the power to the audible and visual alarm, rendering it silent and inactive. When the enclosure is detached from the mounting surface, the triggering mechanism resets the circuit, activating the audible and visual alarm and emitting a warning signal, thus preventing the entire electrical junction box from being stolen.

[0048] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0049] In the description of this utility model, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0050] Currently, while installing anti-theft devices on the cabinet doors can effectively prevent pry-open thefts, such measures are ineffective against thefts committed by completely dismantling the electrical junction box, as they do not cover the fixed structure of the cabinet.

[0051] like Figures 1-5 As shown, this utility model embodiment provides an electrical junction box with anti-tamper alarm function, mainly including: a box body 1, the box body 1 is fixed on the mounting surface 6, the box body 1 has a cavity inside, the cavity contains a core conductive component and a power supply, and the box body 1 is provided with an anti-theft security door 2, an audible and visual alarm 3 and a triggering mechanism 4.

[0052] The audible and visual alarm 3 is connected to a power source. The triggering mechanism 4 can abut against the mounting surface 6.

[0053] When the main body 1 of the enclosure is fixed on the mounting surface 6, the triggering mechanism 4 is pressed by the mounting surface 6 and cuts off the power to the audible and visual alarm 3. At this time, the audible and visual alarm 3 is silent and inactive. When the main body 1 of the enclosure is removed from the mounting surface 6, the triggering mechanism 4 resets and connects the circuit, and the audible and visual alarm 3 is activated and emits a warning signal.

[0054] Specifically, such as Figure 3 As shown, the triggering mechanism 4 mainly includes: a support frame 41, a first spring 42, a pressing plate 43, a micro switch 45, and a guide rod 44.

[0055] The support frame 41 is mounted on the mounting surface of the main body 1. It has a hollow interior. A first spring 42 is fixedly mounted on one inner wall of the support frame 41. A pressing plate 43 is mounted on the free extension end of the first spring 42, allowing it to slide freely within the support frame 41. A micro switch 45 is fixedly mounted on the other inner wall of the support frame 41, corresponding to the position of the pressing plate 43. Adjacent to the micro switch 45, a guide rod 44 is mounted on the outer wall of the support frame 41. One end of the guide rod 44 protrudes from the outer wall of the support frame 41 and abuts against the mounting surface 6. The other end slides through the support frame 41 and the micro switch 45, and is fixedly connected to the pressing plate 43.

[0056] Furthermore, the micro switch 45 mainly includes: a support portion 451 and a pressing portion 452 that is slidably disposed on the support portion 451.

[0057] The support part 451 is fixedly mounted on an inner side wall of the support frame 41, and one end of the guide rod 44 can slide through the support part 451 and is fixedly connected to the pressing plate 43. The squeezing part 452 is opposite to one end of the pressing plate 43, and the squeezing part 452 slides along the support part 451 under the thrust of the pressing plate 43.

[0058] like Figures 4-5 As shown, when the guide rod 44 is pressed by the mounting surface 6, the guide rod 44 pushes the pressing plate 43 to move away from the pressing part 452. During the movement, the pressing plate 43 applies a horizontal force to the first spring 42, compressing the first spring 42. At this time, the pressing plate 43 does not act on the pressing part 452, the micro switch 45 is in the open state, the alarm circuit is not activated, and the audible and visual alarm 3 is silent. When the pressing force on the guide rod 44 disappears, the first spring 42 resets and pushes the pressing plate 43 to move closer to the pressing part 452. During the movement, the pressing plate 43 touches the pressing part 452, causing the pressing part 452 to slide towards the support part 451, closing the micro switch 45, activating the alarm circuit, and thus activating the audible and visual alarm 3 to emit a warning signal.

[0059] Furthermore, to facilitate the installation and disassembly of the main body 1 by staff, in this embodiment, the electrical junction box also includes a mounting mechanism 5.

[0060] Specifically, such as Figure 2 As shown, the installation mechanism 5 mainly includes several parts such as the mounting bracket 51 and the snap-fit ​​assembly 52.

[0061] The mounting brackets 51 are symmetrically fixed to the mounting surface 6 (such as a wall). Each set of mounting brackets 51 has at least one snap-fit ​​groove 511 on the opposite side wall. The corresponding surface of the box body 1 is provided with snap-fit ​​components 52. The number of snap-fit ​​components 52 corresponds to the number of snap-fit ​​grooves 511. The installation of the box body 1 is completed by the engagement and locking of the snap-fit ​​components 52 and the snap-fit ​​grooves 511.

[0062] Furthermore, to make the spacing between the two sets of mounting brackets 51 adjustable to accommodate different sizes of the box body 1, in this embodiment, the two sets of mounting brackets 51 are detachably fixed to the mounting surface 6.

[0063] Furthermore, the snap-fit ​​assembly 52 mainly includes: a housing 521, a snap-fit ​​block 522, a second spring 523, and a disassembly pull rope 524, etc.

[0064] The housing 521 is symmetrically fixed on the mounting surface of the main body 1. Each housing 521 has a sliding groove on one side wall. The locking block 522 slides through the sliding groove and matches the locking groove 511 on the mounting bracket 51. Each housing 521 is provided with a second spring 523. The two ends of the second spring 523 abut against the inner wall of the housing 521 and the inner end of the locking block 522, respectively. The disassembly pull rope 524 spans the two housings 521. Its two ends pass through the housing 521 and the second spring 523 in sequence and are connected to the corresponding locking block 522 to form a linkage release structure.

[0065] Furthermore, to avoid locking failure due to misalignment between the locking block 522 and the locking slot 511, in this embodiment, the outer end of the locking block 522 (i.e., the end inserted into the locking slot 511) is machined into a tapered structure. The tapered surface guides the locking block 522 to automatically align, compensating for positional deviations.

[0066] Furthermore, to improve the wear resistance of the locking block 522, in this embodiment, the locking block 522 is made of 40Cr steel.

[0067] In use, first adjust the distance between the two sets of mounting brackets 51 according to the size of the main body 1, so that the locking block 522 corresponds to the locking groove 511. Then press the main body 1 to make the locking block 522 engage in the locking groove 511, thus completing the installation of the main body 1. During the installation of the main body 1, the guide rod 44 is subjected to the pressure of the wall. The guide rod 44 pushes the pressing plate 43 to move away from the pressing part 452. During the movement, the pressing plate 43 applies a horizontal force to the first spring 42, and the first spring 42 is compressed. At this time, the pressing plate 43 does not act on the pressing part 452, the micro switch 45 is in the open state, the alarm circuit is not connected, and the audible and visual alarm 3 is silent. When a non-staff member disassembles the electrical junction box, the guide rod 44 detaches from the wall, the pressure disappears, and the first spring 42 resets, pushing the pressing plate 43 towards the pressing part 452. During this movement, the pressing plate 43 presses against the pressing part 452, causing the pressing part 452 to slide towards the support part 451, closing the micro switch 45 and activating the alarm circuit. This activates the audible and visual alarm 3, which then emits a warning signal. When a staff member needs to disassemble the box body 1, they simply pull the disassembly rope 524. The locking block 522 disengages from the locking groove 511 under the action of the disassembly rope 524, thus completing the disassembly of the box body 1.

[0068] Furthermore, to enable the electrical junction box to have a heat dissipation function, in this embodiment, multiple heat dissipation holes 11 are provided through the main body 1 of the box. Heat exchange is achieved through the heat dissipation holes 11, thereby achieving the purpose of cooling the inside of the electrical junction box.

[0069] It should be noted that the locking structure of the snap-fit ​​component 52 and the snap-fit ​​groove 511 in this embodiment is suitable for electrical junction boxes weighing between 5kg and 15kg.

[0070] In this embodiment, the anti-theft security door 2 adopts the anti-theft technology commonly used in the prior art, which will not be described in detail in this embodiment.

[0071] For example, the sound and light alarm 3 in this embodiment can be a ZWIN-ESA1006 sound and light alarm 3 or a TH-K-SF08 high-brightness LED sound and light alarm 3.

[0072] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
