Description

Technical Field

[0001] The utility model relates to the technical field of intercoms, in particular to an anti-disassembly and anti-modification intercom. Background Art

[0002] As a two-way mobile communication tool, walkie-talkies are primarily used for short-range voice communication. They can connect multiple walkie-talkies simultaneously for group calls and are portable and readily available. They are widely used in various fields. Their network-free operation, affordability, and ease of use make them an indispensable communication tool in many situations.

[0003] Currently, some intercom casings on the market are assembled using ultrasonic welding, eliminating the need for bolts. This provides some degree of anti-tampering protection, but the effectiveness is limited. Under violent disassembly, a blade can easily cut along the weld seam, easily opening the casing. Even with stamped edges to indicate anti-tampering, this is largely ineffective, and cannot guarantee user installation and use of the product.

[0004] Therefore, the author proposes a walkie-talkie that is anti-disassembly and anti-modification to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide a walkie-talkie that is anti-disassembly and anti-modification, which is provided with a locked lock pin structure and a shell structure that is torn after disassembly, to avoid illegal disassembly and modification, so as to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above object, the present invention provides the following technical solutions: a disassembly and modification-resistant intercom, comprising a lower shell cover and an upper shell cover welded together, with an anti-disassembly and modification structure provided between the lower shell cover and the upper shell cover;

[0007] The anti-tampering structure includes a fragment that is integrally connected to the inner side of the upper shell cover, and a gap groove is formed along the outer edge of the fragment. The bottom surface of the fragment and the lower shell cover are fixed by an inserted locking pin structure, forming a tearing portion at the fragment and an exposed hole on the surface of the upper shell cover that can be torn under external force.

[0008] As an optional solution for the anti-disassembly and anti-modification intercom of the utility model, the gap groove is an annular structure, and the depth is at least half of the thickness of the upper shell cover.

[0009] As an optional solution for the anti-disassembly and anti-modification walkie-talkie described in the utility model, the outer wall of the fragment is integrated with an external thread segment, the inner wall of the gap groove is integrated with an internal thread segment to match the external thread segment, the internal thread segment is threadedly connected to the external thread segment, and the direction of the thread segment is set from top to bottom.

[0010] As an optional solution for the anti-disassembly and anti-modification walkie-talkie described in the utility model, the lock pin structure includes a pin fixedly connected to the bottom surface of the fragment, and a lock seat is integrally connected to the inner wall of the lower shell cover, and the bottom end of the pin is inserted into the lock seat and locked.

[0011] As an optional solution for the anti-disassembly and anti-modification intercom of the utility model, the latch is a strip-shaped structure and is arranged vertically downward.

[0012] As an optional solution for the anti-disassembly and anti-modification intercom of the utility model, the lock seat is an annular hollow socket, and a socket for plugging a pin is formed in the middle.

[0013] As an optional solution for the anti-disassembly and anti-modification intercom described in the utility model, wherein: the two ends of the pin are respectively integrally connected with a strip-shaped lock plate tilted upward, and the end is hook-shaped; an inclined lock hole is opened on the socket corresponding to each lock plate, and the lock plate is inserted and clamped in the lock hole to lock the pin.

[0014] As an optional solution for the anti-disassembly and anti-modification walkie-talkie of the utility model, the lock pin structure is arranged with at least four groups of pins and lock seats, and the rectangular arrays are respectively arranged around the battery inside the lower shell cover.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The anti-disassembly and anti-modification walkie-talkie is locked between the upper and lower shell covers by means of locking pins, so that the four corners of the shell are locked and stressed, making it difficult to disassemble and open without violence;

[0017] 2. The anti-disassembly and anti-modification walkie-talkie is equipped with an anti-disassembly structure and a fragment with a gap groove is set on the outer shell. When the lock pin is violently disassembled, the weakest fragment is pulled apart from the upper shell cover by external force, so that the exposure hole appears on the surface of the upper shell cover. The upper shell cover is damaged, which informs the user that the walkie-talkie shell has been disassembled and opened, and the shell is damaged, making it difficult to continue to use it in a dust-proof and waterproof manner, thereby preventing illegal disassembly and modification.

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] Example 1

[0028] See also Figures 1-6 , an anti-disassembly and anti-modification walkie-talkie, comprising a lower shell cover 1 and an upper shell cover 4 that are welded together, and an anti-disassembly and modification structure is provided between the lower shell cover 1 and the upper shell cover 4;

[0029] The anti-tampering structure includes a fragment 7 integrally connected to the inner side of the upper shell cover 4, a gap groove 9 is formed on the outer edge of the fragment 7, and a locking pin structure is inserted between the bottom surface of the fragment 7 and the lower shell cover 1 to fix it. A tearing portion 10 is formed at the fragment 7, and an exposure hole 11 that can be torn under external force is formed on the surface of the upper shell cover 4, informing the user whether the intercom housing has been disassembled and opened.

[0030] In the first embodiment, the gap groove 9 is annular in structure, and its depth is at least half of the thickness of the upper shell cover 4 , so that the shell wall at the gap groove 9 is weak, making the tearing portion 10 easy to tear under external force.

[0031] Specific instructions:

[0032] The lock pin structure includes a latch pin 5 fixedly connected to the bottom surface of the broken piece 7. The latch pin 5 is a strip-shaped structure, arranged vertically downward, and a strip-shaped lock plate 6 with an upward tilt is integrally connected to both ends of the latch pin 5, and the end is hook-shaped.

[0033] A lock base 2 is integrally connected to the inner wall of the lower shell cover 1. The lock base 2 is a hollow annular socket with a socket 3 formed in the middle for the plugging of the pin 5. An inclined lock hole 8 is provided on the socket 3 corresponding to each lock plate 6. The lock plate 6 is inserted and clamped in the lock hole 8 to lock the pin 5, that is, the bottom end of the pin 5 is inserted into the lock base 2 and locked.

[0034] When the lower shell cover 1 and the upper shell cover 4 are matched and docked, the bottom end of the latch 5 will be aligned with the socket 3 of the lock base 2 and inserted into it, and the two lock plates 6 will be inserted downward together with the latch 5. When the outer surface of the lock plate 6 touches the socket 3, the two lock plates 6 will be elastically bent inward by the force and deformed, and enter the socket 3 together until the bottom surface of the latch 5 hits the inner bottom surface of the socket 3. At this time, the two lock plates 6 will be released one by one through the lock holes 8 on both sides of the socket 3, allowing the lock plates 6 to pass through the lock holes 8.

[0035] At this time, the inner side surface of the upward-slanted lock plate 6 is hooked on the lock hole 8, and the bottom surface of the latch 5 contacts the inner bottom surface of the socket 3, so that the lower shell cover 1 and the upper shell cover 4 are completely locked by the lock pin structure. After that, the edges of the lower shell cover 1 and the upper shell cover 4 are fixed by ultrasonic welding to complete the assembly.

[0036] During violent disassembly, even if the disassembler cuts open the edges of the lower shell cover 1 and the upper shell cover 4 to dissolve the gap, under the locked lock pin structure, under external violent disassembly, the weakest fragment 7 can easily be separated from the upper shell cover 4 by external force, so that the exposure hole 11 appears on the surface of the upper shell cover 4. The upper shell cover 4 is damaged, which informs the user that the intercom housing has been disassembled and opened. To avoid illegal modification, it should be used with caution.

[0037] To prevent fragment 7 from being torn apart during violent disassembly:

[0038] The lock pin structure is arranged with at least four sets of latches 5 and lock seats 2, arranged in a rectangular array around the battery inside the lower shell 1. This arrangement of multiple sets of lock pins prevents accidents, and the rectangular array locks the four corners of the shell, making disassembly difficult and difficult to open without violence.

[0039] In addition, the locking pin structure is arranged next to the battery to prevent external cutting from damaging the entire locking pin, making cutting more difficult and easily touching the battery to cause damage to internal parts, increasing the difficulty of disassembly and modification.

[0040] Need to explain:

[0041] The bottom of each fragment 7 is supported by a locking pin structure. In daily use, the fragment 7 has a certain strength, which is sufficient to ensure normal use.

[0042] Example 2

[0043] On the basis of Example 1, in order to ensure that the broken piece 7 will not be accidentally damaged and the exposure hole 11 will be exposed during daily use:

[0044] See also Figure 7 In this embodiment 2, the outer wall of the fragment 7 is integrated with an external thread segment, and the inner wall of the gap groove 9 is integrated with an internal thread segment to match the external thread segment. The internal thread segment is threadedly connected to the external thread segment, and the thread segment direction is set from top to bottom.

[0045] That is, when the intercom housing is subjected to external pressure, the fragment 7 is not only supported by the lock pin structure, but also by the limiting support of the threaded segment. When subjected to external pressure, the external threaded segment on the fragment 7 is supported by the internal threaded segment in the upper shell cover 4. Compared with the gap groove 9 in Example 1, the external bearing pressure is enhanced, preventing the fragment 7 from being ruptured inward by pressure under normal use, thereby ensuring the daily use effect.

[0046] At the same time, the difficulty of disassembly increases, and it is easier to apply force to damage and tear out the exposed hole (11) under increased violent disassembly.

[0047] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
