Description

Technical Field

[0001] This application relates to the field of signage technology, and more specifically to a sign with a replaceable back panel. Background Technology

[0002] Signage is a type of sign used to create directional information. It contains text, images, and other information to indicate directions and provide warnings.

[0003] Patent document (CN215868412U) discloses a sign, including a mounting backplate and a warning sign. The warning sign is covered by a mounting frame, and a pressure plate frame is elastically connected inside the mounting frame. Replacement slots are provided at the top and bottom of the mounting frame. A set of fixing hook plates is slidably connected to the rear wall of the warning sign, and a fixing spring is fixedly connected between the fixing hook plates. A set of closing hook frames is fixedly connected to the front wall of the mounting backplate, and the fixing hook plates cooperate with the closing hook frames. It should be noted that when it is necessary to remove the mounting backplate, in order to avoid damaging the connection between the mounting backplate and the warning sign or exposing the fixing bolts on the mounting backplate, the fixing hook plates should be separated from the closing hook frames first. Only after removing the warning sign can the mounting backplate be exposed and then disassembled. However, if the mounting backplate is simply removed and installed in another location, the warning sign has already separated from the mounting backplate when it was previously removed. Therefore, when installing the mounting backplate, it is necessary to align the warning sign with the mounting backplate again before installation. If multiple signs need to be repositioned in a certain event, this alignment process is quite cumbersome and inconvenient.

[0004] Therefore, there is a need for a sign that eliminates the need for a direct alignment step during reinstallation and makes installation easier by replacing the mounting backplate. Summary of the Invention

[0005] The main objective of this application is to provide a sign with an easily replaceable mounting backplate. The sign includes a mounting backplate, a warning sign, and a hinge assembly. One end of the mounting backplate has two first protrusions, each with a hinge hole at its facing end. One end of the warning sign has a second protrusion with a through hole, the sidewall of which has a sliding hole. The hinge assembly includes two lifting rods and a pressing member. The two lifting rods are raised and lowered within the through hole, and their orientations are opposite. The lifting rods each have a first inclined surface at opposite ends. The pressing member is slidably disposed in the sliding hole. The pressing member has two second inclined surfaces, which respectively fit against the two first inclined surfaces. When the pressing member slides, the lifting rod extends into or out of the hinge hole. When the position of the mounting backplate needs to be changed, only the warning sign needs to be flipped over, without removing the warning sign. This eliminates the need to repeat the step of aligning the warning sign with the mounting backplate during reinstallation. Compared with the prior art, this has the advantage of saving the alignment step during reinstallation and making installation more convenient.

[0006] Another objective of this application is to provide a sign with a replaceable mounting backplate, wherein the mounting backplate has a plurality of first snap-fit ​​holes at the end opposite to the first protrusion, and the warning sign has a bent portion at the end opposite to the second protrusion, the bent portion having second snap-fit ​​holes. The sign with a replaceable mounting backplate further includes a snap-fit ​​component. When the warning sign is attached to the mounting backplate and the first snap-fit ​​holes are aligned with the second snap-fit ​​holes, the snap-fit ​​component passes through the second snap-fit ​​holes and snaps into the first snap-fit ​​holes to fix the position of the warning sign.

[0007] To achieve at least one of the above-mentioned objectives, this application provides a signboard with an easily replaceable backplate, wherein the signboard with an easily replaceable backplate includes: The mounting backplate has two first protrusions at one end, and each of the two first protrusions has a hinge hole at the opposite end. A warning sign, one end of which has a second protrusion, the second protrusion having a through hole, and the sidewall of the through hole having a sliding hole; A hinge assembly includes two lifting rods and a pressing member. The two lifting rods are raised and lowered in the through hole, and the two lifting rods are oriented in opposite directions. Each of the two lifting rods has a first inclined surface at one end facing each other. The pressing member is slidably disposed in the sliding hole and has two second inclined surfaces. The two second inclined surfaces are respectively in contact with the two first inclined surfaces. When the pressing member slides, the lifting rods extend into or retract from the hinge hole.

[0008] In one or more embodiments of this application, the end of the mounting back plate away from the first boss has a plurality of first snap-fit ​​holes, the end of the warning sign away from the second boss has a bent portion, the bent portion has a second snap-fit ​​hole, and the sign for easy replacement of the mounting back plate further includes a snap-fit ​​member. When the warning sign is attached to the mounting back plate and the first snap-fit ​​hole is aligned with the second snap-fit ​​hole, the snap-fit ​​member passes through the second snap-fit ​​hole and snaps into the first snap-fit ​​hole.

[0009] In one or more embodiments of this application, the mounting backplate has a plurality of connection holes.

[0010] In one or more embodiments of this application, a first magnet is provided on the front side of the mounting back plate, and a second magnet is provided on the side of the warning sign near the mounting back plate.

[0011] In one or more embodiments of this application, the hinge assembly further includes two sliding members and two elastic members. The sidewall of the sliding hole has two receiving holes, and each receiving hole can be slidably provided with one of the sliding members. The two ends of the elastic members are respectively connected to the sliding members and the bottom wall of the receiving holes. The end of the pressing member away from the lifting rod has a reduced diameter portion. When the pressing member is pressed and the lifting rod extends into the hinge hole, the sliding member extends out of the receiving hole and abuts against the sidewall of the reduced diameter portion.

[0012] In one or more embodiments of this application, the second boss further has a pull wire channel communicating with the receiving hole, and the hinge assembly further includes a pull rope and a screwing member. The screwing member is threadedly connected to the end of the pull wire channel near the outside, and the two ends of the pull rope are respectively connected to the sliding member and the screwing member.

[0013] In one or more embodiments of this application, the sidewall of the pressing member also has two third inclined surfaces, and when the lifting rod exits the hinge hole, the sliding member abuts against the third inclined surfaces.

[0014] In one or more embodiments of this application, the reduced diameter portion has a first annular groove.

[0015] In one or more embodiments of this application, the hinge assembly further includes two retaining springs, which are respectively fixedly connected to both sides of the second boss. Each lifting rod has a second annular groove, and each retaining spring is sleeved in the corresponding second annular groove.

[0016] In one or more embodiments of this application, the snap-fit ​​component includes an insertion portion, the two ends of which each have two bent sections and abutment portions. The snap-fit ​​component is made of plastic. A third magnetic ring is provided on the abutment portion. The second snap-fit ​​hole includes a conical hole portion with a radial dimension that decreases sequentially. A fourth magnetic ring is provided on the bottom wall of the countersunk hole portion. When the snap-fit ​​component is snapped into the first snap-fit ​​hole, the bent sections bend and deform, and the third magnetic ring and the fourth magnetic ring attract each other.

[0017] In this embodiment, the sign with a replaceable backplate includes a backplate, a warning sign, and a hinge assembly.

[0023] Indicative signage for easy replacement of mounting backplate, see reference. Figures 1 to 5 According to a preferred embodiment of the present invention, a sign with an easily replaceable mounting backplate includes a mounting backplate 10, a warning sign 20, and a hinge assembly 30.

[0024] Specifically, such as Figure 1 and Figure 2As shown, one end of the mounting back plate 10 has two first protrusions 101, and each of the two first protrusions 101 has a hinge hole 1011 at the opposite end; in addition, one end of the warning sign 20 has a second protrusion 201, the second protrusion 201 has a through hole 2011, and the side wall of the through hole 2011 has a sliding hole 2012; furthermore, the hinge assembly 30 includes two lifting rods 301 and a pressing member 302. The two lifting rods 301 are raised and lowered in the through hole 2011, and the two lifting rods 301 are oriented in opposite directions. Each of the two lifting rods 301 has a first inclined surface 3011 at the opposite end. The pressing member 302 is slidably disposed in the sliding hole 2012. The pressing member 302 has two second inclined surfaces, and the two second inclined surfaces are respectively in contact with the two first inclined surfaces 3011. When the pressing member 302 slides, the lifting rods 301 extend into or retract from the hinge hole 1011.

[0025] It should be noted that during installation, the mounting back plate 10 is first installed on the fixed wall by adhesive or bolts. Then, the warning sign 20 is installed on the mounting back plate 10. Specifically, the warning sign 20 is positioned on the front side of the mounting back plate 10, and the second protrusion 201 is positioned between the two first protrusions 101 in the height direction, with the through hole 2011 aligned with the hinge hole 1011. Subsequently, the operator only needs to press the pressing member 302. As the pressing member 302 moves along the sliding hole 2012 towards the other end of the warning sign 20, the first inclined surface 3011 and the second inclined surface are in contact with each other. The two lifting rods 301 are subjected to an axial moving component force, causing the two lifting rods 301 to move in opposite directions and extend into the corresponding hinge holes 1011, thus realizing the rotational connection between the warning sign and the mounting back plate 10. It should also be noted that when the mounting backplate 10 needs to be repositioned, this application only needs to flip the warning sign 20 to expose the mounting backplate 10, and remove the mounting backplate 10 and the warning sign 20 connected to it. After the mounting backplate 10 is moved to another position, it is not necessary to face the warning sign 20 again. Instead, the warning sign 20 can be flipped directly and made to fit against the mounting backplate 10. It is evident that, compared to the prior art where the warning sign 20 needs to be faced again after reinstalling the mounting backplate 10, this application has the advantage of eliminating the facing step during reinstallation and making installation more convenient.

[0026] Furthermore, after the warning sign 20 is rotatably connected to the mounting back plate 10, in order to fix the angle of the warning sign 20, as follows: Figure 2 and Figure 4As shown, the mounting back plate 10 has a plurality of first snap-fit ​​holes 102 at one end away from the first boss 101, and the warning sign 20 has a bent portion 202 at one end away from the second boss 201. The bent portion 202 has a second snap-fit ​​hole 2021. The sign for easy replacement of the mounting back plate also includes a snap-fit ​​member 40. When the warning sign 20 is attached to the mounting back plate 10 and the first snap-fit ​​hole 102 is directly opposite the second snap-fit ​​hole 2021, the snap-fit ​​member 40 passes through the second snap-fit ​​hole 2021 and snaps into the first snap-fit ​​hole 102.

[0027] It should be noted that during installation, after the warning sign 20 and the mounting back plate 10 are rotatably connected through the lifting rod 301, the warning sign 20 is made to fit against the mounting back plate 10, and the bent part 202 fits against the end of the mounting back plate 10 away from the first boss 101. At this time, the first snap-fit ​​hole 102 and the second snap-fit ​​hole 2021 are aligned. Subsequently, the installer only needs to insert the corresponding snap-fit ​​piece 40 into the second snap-fit ​​hole 2021, and the snap-fit ​​piece 40 will snap into the first snap-fit ​​hole 102 after passing through the second snap-fit ​​hole 2021, thereby fixing the position of the warning sign 20.

[0028] Furthermore, to provide installation conditions for the mounting backplate 10 to be bolted to the external wall, such as... Figure 1 As shown, the mounting backplate 10 has a plurality of connection holes 103.

[0029] It should be noted that, in this application, the connecting hole 103 is an oblong hole.

[0030] Furthermore, since the mounting backplate 10 and the warning sign 20 are not rotatably connected during the initial installation, pre-fixation is required before rotatable connection, such as... Figure 1 As shown, the front of the mounting back plate 10 is provided with a first magnet 104, and the side of the warning sign 20 near the mounting back plate 10 is provided with a second magnet.

[0031] It should be noted that during installation, first make the warning sign 20 fit against the mounting back plate 10, and make the first magnet 104 attract the second magnet. Then, move the position of the warning sign 20 so that the through hole 2011 is aligned with the hinge hole 1011, and then press the pressing member 302.

[0032] Furthermore, to ensure that after pressing the pressing member 302, the pressing member 302 will not spring back and disengage from the sliding hole 2012 under non-human-caused circumstances, such as... Figure 5As shown, the hinge assembly 30 further includes two sliding members 303 and two elastic members 304. The sidewall of the sliding hole 2012 has two receiving holes 2013. Each receiving hole 2013 can be slidably provided with a sliding member 303. The two ends of the elastic member 304 are respectively connected to the sliding member 303 and the bottom wall of the receiving hole 2013. The pressing member 302 has a reduced diameter portion 3021 at the end away from the lifting rod 301. When the pressing member 302 is pressed and the lifting rod 301 extends into the hinge hole 1011, the sliding member 303 extends out of the receiving hole 2013 and abuts against the sidewall of the reduced diameter portion 3021.

[0033] It should be noted that when the pressing member 302 is pressed, the reduced diameter portion 3021 is directly opposite the lifting rod 301 in the height direction. Then, the sliding member 303 moves towards the reduced diameter portion 3021 under the action of the elastic member 304 and abuts against the reduced diameter portion 3021. As a result, the pressing member 302 is blocked by the elastic member 304 and is difficult to disengage from the sliding hole 2012.

[0034] Furthermore, such as Figure 5 As shown, the second boss 201 also has a pull cable channel 2014, which communicates with the receiving hole 2013. The hinge assembly 30 also includes a pull rope 305 and a screwing member 306. The screwing member 306 is threadedly connected to the end of the pull cable channel 2014 near the outside. The two ends of the pull rope 305 are respectively connected to the sliding member 303 and the screwing member 306.

[0035] It should be noted that when the warning sign 20 needs to be replaced, the warning sign 20 is removed from the mounting back plate 10. The installer only needs to pull the pull rope 305 and make the sliding member 303 retract into the receiving hole 2013 and no longer block the pressing member 302. At this time, one end of the pressing member 302 can be clamped and the pressing member 302 can be removed.

[0036] Furthermore, to prevent the pressing member 302 from disengaging from the sliding hole 2012 when it is not pressed, as follows: Figure 5 As shown, the side wall of the pressing member 302 also has two third inclined surfaces 3022. When the lifting rod 301 exits the hinge hole 1011, the sliding member 303 abuts against the third inclined surfaces 3022.

[0037] It should be noted that by the sliding member 303 pressing against the pressing member 302, a frictional force is provided to the pressing member 302, preventing the pressing member 302 from dislodging from the sliding hole 2012.

[0038] Furthermore, to facilitate gripping the pressing member 302, such as... Figure 3 As shown, the reduced diameter portion 3021 has a first annular groove 3023.

[0039] Furthermore, to prevent the lifting rod 301 from detaching from the through hole 2011 under normal conditions, such as... Figure 3 As shown, the hinge assembly 30 also includes two retaining springs 307, which are fixedly connected to both sides of the second boss 201 respectively. The fixed connection method includes, but is not limited to, welding. Each lifting rod 301 has a second annular groove 3012, and each retaining spring 307 is sleeved in the corresponding second annular groove 3012.

[0040] Furthermore, to specifically implement the card connector 40, such as Figure 4 As shown, the snap-fit ​​component 40 includes an insertion portion 401, with two bent sections 4011 and an abutment portion 4012 at each end. The snap-fit ​​component 40 is made of plastic. A third magnetic ring 40121 is provided on the abutment portion 4012. The second snap-fit ​​hole 2021 includes a conical hole portion 20212 with a radially decreasing countersunk portion 20211. A fourth magnetic ring 20213 is provided on the bottom wall of the countersunk portion 20211. When the snap-fit ​​component 40 is snapped into the first snap-fit ​​hole 102, the bent sections 4011 bend and deform, and the third magnetic ring 40121 and the fourth magnetic ring 20213 are attracted together.

[0041] It should be noted that when the snap-fit ​​member 40 is inserted into the second snap-fit ​​hole 2021, the bent section 4011 first contacts the tapered hole portion 20212 and gradually bends inward until the snap-fit ​​member 40 extends into the first snap-fit ​​hole 102, and the bent section 4011 abuts against the hole wall of the first snap-fit ​​hole 102. The friction provided by the bent section 4011 fixes the position of the snap-fit ​​member 40. At the same time, the abutting part 4012 abuts against the bottom wall of the countersunk hole portion 20211. In addition, to improve the fastening effect, when the abutting part 4012 abuts against the bottom wall of the countersunk hole portion 20211, the third magnetic ring 40121 and the fourth magnetic ring 20213 are attracted together.

[0042] In summary, the signboard with an easy-to-replace back panel described in the embodiments of this application is explained, which provides advantages such as eliminating the need for a direct alignment step during reinstallation and making installation more convenient.
