Description

Technical Field

[0001] This invention relates to the field of signage technology, and more particularly to a tamper-proof sign. Background Technology

[0002] A sign, as the name suggests, is a sign used to make identifications. It contains text, pictures, and other content to display information. Signs are generally attached to products to identify the product's brand and model. To prevent counterfeiting, signs usually have anti-counterfeiting stickers. However, most anti-counterfeiting stickers are pasted on the outside of the sign, which makes them less secure and easier to damage, resulting in poor anti-counterfeiting effectiveness.

[0003] Existing anti-tamper signs are mostly adhesive or screw-fixed structures, which are easily replaced. Existing replaceable sign devices also have certain shortcomings, such as complex structure, high manufacturing cost, and cumbersome replacement. At the same time, their anti-tamper capabilities cannot meet actual needs. Summary of the Invention

[0004] Based on the above analysis, the present invention aims to provide a tamper-proof sign to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A tamper-proof sign includes an equipment connection device, a display device, and an internal connection device; the equipment connection device contains a detachable internal connection device, and the display device is installed on one side of the internal connection device.

[0007] Furthermore, the device connection device includes a device body, a threaded hole, a device groove, and a press-to-remove hole; the device body has a device groove, a threaded hole, and a press-to-remove hole.

[0008] Furthermore, the internal connecting device includes a connecting plate, an elastic plate, a second snap-fit ​​protrusion, a bolt positioning hole, a fastening bolt, and a disassembly through hole;

[0009] Both the upper and lower sides of the connecting plate are fixed with elastic plates, and a second snap-fit ​​protrusion is installed on one end of each elastic plate. The second snap-fit ​​protrusion is symmetrically arranged relative to the connecting plate and snaps into the display device.

[0010] The connecting plate is provided with bolt positioning holes, and the bolt positioning holes correspond to the positions of the threaded holes in the equipment connecting device.

[0011] A fastening bolt is installed in the bolt positioning hole, and the fastening bolt is connected to the threaded hole in the equipment connection device by a thread.

[0012] The connecting plate has a disassembly through hole, which corresponds to the position of the press disassembly hole in the equipment connecting device.

[0013] Furthermore, the display device includes a signboard, a side connecting plate, a chamfered connecting plate, and a first snap-fit ​​protrusion; the signboard is fixed with side connecting plates on both the upper and lower sides, and the first snap-fit ​​protrusion and the chamfered connecting plate are disposed on the side connecting plates.

[0014] Furthermore, positioning blocks are installed on both the upper and lower sides of the connecting plate.

[0015] Furthermore, the elastic plate has grooves on both sides of the second snap-fit ​​protrusion.

[0016] Furthermore, reinforcing ribs are provided between the elastic plate and the connecting plate.

[0017] Furthermore, the information display side of the signboard is covered with a transparent panel, and a through slot is provided in the transparent panel, in which an information card is installed.

[0018] Furthermore, the display surface of the display device is recessed by 0.1-0.2 mm relative to the surface of the equipment connecting device.

[0019] Furthermore, the equipment connection device, display device, and internal connection device are all manufactured using injection molding.

[0020] Furthermore, the tamper-proof sign also includes an internal pressing and disassembly device, which includes a pressing block, a pressing cylinder, and a pressing spring; the pressing cylinder is slidably connected to the pressing and disassembly hole in the equipment connection device; the pressing cylinders are connected to each other through the pressing block, and the pressing block is connected to the equipment connection device through the pressing spring.

[0021] Furthermore, the internal pressing and disassembly device also includes a lever block, an anti-breakage locking block, and a rotating rod; lever blocks are rotatably connected to both the upper and lower sides of the pressing block, and a long groove is opened in the lever block. One end of the lever block is fixed to the inner surface of the equipment connecting device, and the other end of the lever block is provided with a first round rod, which is installed in the long groove of the lever block. A sliding groove for the anti-breakage locking block is opened in the equipment connecting device, and a second round rod is provided at one end of the anti-breakage locking block, which is installed in the long groove of the lever block. A pressing arc block is provided at the other end of the anti-breakage locking block.

[0022] The above technical solution has at least one of the following beneficial effects:

[0023] (1) The setting of equipment connection device, display device and internal connection device makes the replaceable signboard without bolts and buckles on the outside of the equipment, which avoids the defects of traditional signsboards that can be replaced at will. At the same time, it has the characteristics of simple structure, low manufacturing cost and easy replacement.

[0024] (2) The fastening bolts are built in, and the first and second snap-fit ​​protrusions are snapped together, so that the sign cannot be removed from the outside of the equipment, but can be easily removed and replaced from the inside of the equipment, which can effectively prevent destructive removal.

[0025] (3) The setting of pressing block, pressing cylinder and pressing spring allows the operator to squeeze out the display device by pressing the pressing block. The structure is simple, the production difficulty is low and the use is convenient.

[0026] (4) The lever support block, anti-tampering locking block and rotating rod are set up in coordination with the pressing block, pressing cylinder and pressing spring. When the operator presses the pressing block, the anti-tampering locking block retracts into the equipment and no longer abuts against the chamfer of the connecting plate of the side connecting plate for limiting. At the same time, the pressing cylinder extends the pressing plate out of the equipment and pushes the display device out. This avoids the anti-tampering locking block abutting against the chamfer of the connecting plate of the side connecting plate for limiting when the pressing block is not pressed. This prevents personnel from removing the display device from the outside of the equipment by suction cup, sticking and pulling or other technical means.

[0027] In this invention, the above-described technical solutions can be combined with each other to achieve more preferred combinations. Other features and advantages of this invention will be set forth in the following description, and some advantages may become apparent from the description or be learned by practicing the invention. The objects and other advantages of this invention can be realized and obtained from what is particularly pointed out in the description and drawings. Attached Figure Description

[0039] Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which form part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0040] Example 1

[0041] One specific embodiment of the present invention discloses a tamper-proof sign, such as... Figure 1 , Figure 3 As shown, an anti-tamper sign includes an equipment connection device 1, a display device 2, and an internal connection device 3; the equipment connection device 1 is equipped with a detachable internal connection device 3, and the display device 2 is installed on one side of the internal connection device 3.

[0042] The display device 2 is installed inside the connecting device through the internal connecting device 3, so that the connecting components are not exposed on the surface of the equipment and the display device 2, avoiding the defects of traditional signs that can be replaced at will. At the same time, it has the advantages of simple structure, low manufacturing cost and easy replacement.

[0043] Preferred, such as Figure 2 As shown, the device connection device 1 includes a device body 11, a threaded hole 12, a device groove 13, and a press-to-remove hole 14; the device body 11 has a device groove 13, a threaded hole 12, and a press-to-remove hole 14.

[0044] The equipment groove 13 is used to create installation space for the internal connecting device 3 and the display device 2, so that the internal connecting device 3 is not exposed outside the equipment; the threaded hole 12 is used to make threaded connection through the fastening bolt 35 to install and fix the internal connecting device 3 and the equipment body 11; the press-to-remove hole 14 is used to allow the display device 2 to be disassembled from inside the equipment body 11, so that the display device 2 can be easily and quickly disassembled from the inside.

[0045] Preferred, such as Figure 5 As shown, the internal connecting device 3 includes a connecting plate 31, an elastic plate 32, a second snap-fit ​​protrusion 33, a bolt positioning hole 34, a fastening bolt 35, and a disassembly through hole 37.

[0046] Both the upper and lower sides of the connecting plate 31 are fixed with elastic plates 32. One end of each elastic plate 32 is equipped with a second snap-fit ​​protrusion 33. The second snap-fit ​​protrusion 33 is symmetrically arranged relative to the connecting plate 31 and snaps with the display device 2.

[0047] The connecting plate 31 is provided with a bolt positioning hole 34, which corresponds to the position of the threaded hole 12 in the equipment connecting device 1.

[0048] A fastening bolt 35 is installed in the bolt positioning hole 34, and the fastening bolt 35 is threadedly connected to the threaded hole 12 in the equipment connection device 1.

[0049] The connecting plate 31 has a disassembly through hole 37, which corresponds to the position of the pressing disassembly hole 14 in the equipment connecting device 1.

[0050] The connecting plate 31 is used to connect and fix the device body 11; the elastic plate 32 and the second snap-fit ​​protrusion 33 are used to cooperate with the first snap-fit ​​protrusion 24 to fix the display device 2. The elastic plate 32 has slight elasticity to reduce the force required to disassemble the display device 2 from the inside of the device; the bolt positioning hole 34 corresponds to the thread position in the device connecting device 1 and guides the fastening bolt 35; the disassembly through hole 37 corresponds to the position of the pressing disassembly hole 14 and acts in the same way as the pressing disassembly hole 14, so that the display device 2 can be disassembled from the inside of the device body 11 by applying force, making it convenient and quick to disassemble the display device 2 from the inside.

[0051] Preferred, such as Figure 4 As shown, the display device 2 includes a signboard 21, a side connecting plate 22, a connecting plate chamfer 23, and a first snap-fit ​​protrusion 24; the signboard 21 is fixed with side connecting plates 22 on both the upper and lower sides, and the first snap-fit ​​protrusion 24 and the connecting plate chamfer 23 are disposed on the side connecting plate 22.

[0052] The signboard 21 is used to identify and display information; the lateral connecting plate 22 is used to guide the signboard 21 to be displayed in a positive direction on the surface of the equipment body 11, and plays a guiding and limiting role; the chamfer 23 of the connecting plate and the first snap-fit ​​protrusion 24 and the second snap-fit ​​protrusion 33 cooperate with each other. During installation, the first snap-fit ​​protrusion 24 deforms and intrudes into the chamfer 23 of the connecting plate. After installation, the first connecting protrusion resets and is locked with the second snap-fit ​​protrusion 33. When disassembling from inside the equipment, the first snap-fit ​​protrusion 24 deforms again and intrudes into the chamfer 23 of the connecting plate, so that the display device 2 is moved out of the equipment body 11.

[0053] Preferably, positioning blocks are installed on both the upper and lower sides of the connecting plate 31.

[0054] The width formed by the positioning block and the connecting plate 31 is the same as the width of the equipment groove 13, and the length of the connecting plate 31 is the same as the length of the equipment groove 13.

[0055] Preferably, the elastic plate 32 has grooves on both sides of the second snap-fit ​​protrusion 33.

[0056] The groove design reduces the force-bearing width of the elastic plate 32, which further reduces the force required to disassemble the display device 2 from inside the equipment. This reduces the force-bearing area of ​​the elastic plate 32, allowing for the use of less force during disassembly. It should be noted that the maximum deformation of the elastic plate 32 is insufficient to allow the first snap-fit ​​protrusion 24 to intrude into the location of the second snap-fit ​​block and directly remove the display device 2 from the equipment connection device 1 from the outside of the equipment.

[0057] Preferably, a reinforcing rib is provided between the elastic plate 32 and the connecting plate 31.

[0058] The reinforcing ribs are designed to strengthen the structural strength of the connecting plate 31 and increase the difficulty of disassembly by force.

[0059] Preferred, such as Figure 6 As shown, the information display side of the signboard 21 is covered with a transparent plate 25, and a through slot 26 is provided in the transparent plate 25, and an information card is installed in the slot 26.

[0060] The transparent panel 25 and slot 26 further reduce the cost of replacing the sign. When the content of the sign needs to be changed, only the information card in the slot 26 needs to be replaced.

[0061] Preferably, the display surface of the display device 2 is recessed by 0.1-0.2 mm relative to the surface of the equipment connecting device 1.

[0062] The fact that the display surface of the display device 2 is recessed by 0.1-0.2mm relative to the surface of the equipment connection device 1 reduces the stress point during violent dismantling, further preventing the possibility of the display device 2 being forcibly dismantled.

[0063] Preferably, the equipment connection device 1, the display device 2, and the internal connection device 3 are all manufactured by injection molding.

[0064] The equipment connection device 1, display device 2 and internal connection device 3 are manufactured using an injection molding process, which is simple to produce and has low manufacturing cost. This is beneficial for mass production and control of sign production costs.

[0065] During installation, the internal connecting device 3 is first fixed inside the equipment groove 13 of the equipment connecting device 1 by tightening bolts 35. Then, the display device 2 is snapped into the equipment groove 13. The second snap-fit ​​protrusion 33 of the internal connecting device 3 is snapped into the first snap-fit ​​protrusion 24 of the display device 2, which is convenient to install.

[0066] Example 2

[0067] This embodiment 2 is based on embodiment 1, but adds an internal pressing and disassembly device 4; for example Figure 7 , Figure 8 , Figure 9 As shown, the anti-tamper sign also includes an internal pressing and disassembly device 4, which includes a pressing block 41, a pressing cylinder 45, and a pressing spring 46. The pressing cylinder 45 is slidably connected to the pressing and disassembly hole 14 in the equipment connection device 1. The pressing cylinders 45 are connected to each other by the pressing block 41, and the pressing block 41 is connected to the equipment connection device 1 by the pressing spring 46.

[0068] The pressing block 41 and pressing cylinder 45 allow the operator to apply force to the display device 2 by pressing the pressing block 41 and simultaneously pressing the pressing cylinder 45, so that the first locking protrusion 24 and the second locking protrusion 33 are no longer locked together. The simultaneous application of force by multiple pressing cylinders 45 makes it easy and quick to remove the display device 2. It has the advantages of simple structure, low production difficulty and convenient use.

[0069] Preferably, the internal pressing and disassembly device 4 further includes a lever block 42, an anti-breakage locking block 43, and a rotating rod 44; the upper and lower sides of the pressing block 41 are rotatably connected to the lever block 42, the lever block 42 has an elongated groove, one end of the lever block 42 is fixed to the inner surface of the equipment connecting device 1, the other end of the lever block 42 is provided with a first round rod, the first round rod is installed in the elongated groove of the lever block 42, the equipment connecting device 1 has a sliding groove for the anti-breakage locking block 43 to slide, one end of the anti-breakage locking block 43 is provided with a second round rod, the second round rod is installed in the elongated groove of the lever block 42, and the other end of the anti-breakage locking block 43 is provided with a pressing arc-shaped block.

[0070] The lever block 42, the anti-tamper locking block 43, and the rotating rod 44 are configured to cooperate with the pressing block 41, the pressing cylinder 45, and the pressing spring 46. When the operator presses the pressing block 41, the anti-tamper locking block 43 retracts into the equipment, and the anti-tamper locking block 43 no longer abuts against the chamfer 23 of the connecting plate of the side connecting plate 22 for limitation. At the same time, the pressing cylinder 45 extends the pressing plate outward from the equipment and pushes out the display device 2. This avoids the situation where, when the pressing block 41 is not pressed, the anti-tamper locking block 43 abuts against the chamfer 23 of the connecting plate of the side connecting plate 22 for limitation, thus preventing personnel from removing the display device 2 from the outside of the equipment by suction cups, sticking, or other technical means.

[0071] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
