Description

Technical Field

[0001] This utility model relates to the technical field of directional signage devices, specifically to a connection device for the internal structure of a sign body. Background Technology

[0002] With the rapid development of rail transit cities, wayfinding signage systems are also undergoing rapid iteration and upgrading. The latest wayfinding systems include two types: conventional static lightbox signs and dynamic electronic signs, and their locations overlap. Based on this premise, the two types of signs are integrated into a single design.

[0003] The installation and subsequent operation and maintenance of conventional integrated signboards are too complicated. The internal structural components of conventional signboards are fixed with screws of different sizes, making installation and disassembly time-consuming and labor-intensive. Utility Model Content

[0004] This utility model provides a connection device for the internal structure of a signboard, which solves the problems of the complicated installation and subsequent operation and maintenance procedures of existing conventional integrated signsboards, the use of screws to fix the internal structural components of conventional signsboards, and the time-consuming and labor-intensive installation and disassembly of various screws of different sizes.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:

[0006] A connection device for the internal structure of a signboard includes a first fixing member and a second fixing member. The first fixing member is disposed on the signboard frame, and the second fixing member is disposed on the back panel of the electronic screen. The first fixing member and the second fixing member are connected in cooperation.

[0007] The beneficial effects of this invention are that, through this device, the electronic screen back panel and the card frame can be easily connected in both separated and snap-fit ​​states with a simple press. This simplifies the construction, installation, operation, and maintenance procedures, reduces operation time, and improves the work efficiency of installation and maintenance personnel.

[0008] Based on the above technical solution, the present invention can be further improved as follows.

[0009] Furthermore, the first fixing component includes a first fixing platform, a slider, a positioning buckle, a stabilizing column, and an elastic element. The first fixing platform is fixedly mounted on the card frame. A through hole is provided at the end of the first fixing platform away from the card frame. The stabilizing column and the elastic element are disposed inside the first fixing platform. One end of the elastic element is fixedly connected to the first fixing platform, and the other end of the elastic element is fixedly connected to the bottom end of the stabilizing column. The other end of the stabilizing column passes through the through hole. The slider and the positioning buckle are disposed opposite each other on the upper part of the first fixing platform. The second fixing component is engaged between the slider and the positioning buckle.

[0010] The beneficial effect of adopting the above-mentioned further solution is that the stabilizing column and the elastic element are sequentially arranged inside the first fixed platform. The elastic element pushes the stabilizing column to extend and slide, and by pushing the stabilizing column to extend and slide, the second fixed element is engaged or disengaged between the slider and the positioning buckle.

[0011] Furthermore, the stabilizing column is a stepped structural component, with the diameter of the stabilizing column at one end through the through hole being smaller than the diameter of the other end, and the diameter of this end being smaller than the diameter of the through hole.

[0012] The beneficial effect of adopting the above-mentioned further solution is that the stabilizing column is set as a stepped structural component. When the elastic element pushes the stabilizing column to extend and slide, the end of the stabilizing column with a larger diameter abuts against the inner wall of the through hole, so that the end of the stabilizing column with a smaller diameter abuts against the second fixing component. By pushing the stabilizing column to extend and slide through the elastic element, the second fixing component is engaged or disengaged between the slider and the positioning buckle.

[0013] Furthermore, the stabilizing column is a retractable structural component.

[0014] The beneficial effect of adopting the above-mentioned further solution is that by setting the stabilizing column as a telescopic structural component, when the elastic element pushes the stabilizing column to extend and slide, the expansion force and rebound force of the elastic element can be reduced, thus extending the service life of the elastic element and the stabilizing column.

[0015] Furthermore, the elastic element is a spring.

[0016] The beneficial effect of adopting the above-mentioned further solution is that by setting the elastic element as a spring, the elastic element has an expansion force and a rebound force, so that the elastic element can act on the stabilizing column according to its own elastic force, and one end of the stabilizing column abuts against the second fixing element.

[0017] Furthermore, there is a gap between the slider and the positioning buckle, and the opposing sides of the slider and the positioning buckle are both inclined, and the two inclined surfaces are parallel.

[0018] The advantage of adopting the above-described further solution is that the two inclined surfaces between the slider and the positioning buckle are arranged in parallel. This allows the second fixing member to be engaged or disengaged between the slider and the positioning buckle.

[0019] Furthermore, the top surface of both the slider and the top surface of the positioning buckle are inclined surfaces, and the ends of the slider and the positioning buckle that are opposite each other are higher than the other end.

[0020] The beneficial effect of adopting the above-mentioned further solution is that the top surface of both the slider and the top surface of the positioning buckle are inclined surfaces. When the elastic element pushes the stabilizing column to extend and slide, the second fixing member slides inclinedly into the gap between the slider and the positioning buckle along the top surface of the positioning buckle. When the elastic element continues to push the stabilizing column forward to extend and slide, the second fixing member slides along the inclined surface in the gap of the slider to the top and then slides out along the top surface of the slider. This allows the second fixing member to engage or disengage depending on the different forces with which the elastic element pushes the stabilizing column forward. This simplifies the construction, installation, operation, and maintenance procedures, reduces operation time, and improves the work efficiency of installation and maintenance personnel.

[0021] Furthermore, the second fixing member includes a second fixing platform, a locking member, and a rotating shaft. An inner groove is provided on one side of the second fixing platform. Both ends of the rotating shaft are locked in the inner groove. One end of the locking member is rotatably set in the inner groove through the rotating shaft. The other end of the locking member extends out of the inner groove and is locked between the slider and the positioning buckle.

[0022] The beneficial effect of adopting the above-mentioned further solution is that an inner groove is opened on the second fixed platform, and one end of the locking component is placed in the inner groove, while the other end of the locking component extends outside the inner groove. This allows the locking component to engage or disengage according to the different forces exerted by the elastic element pushing the stabilizing column forward. This simplifies the construction, installation, operation, and maintenance procedures, reduces operation time, and improves the work efficiency of installation and maintenance personnel.

[0023] Furthermore, the upper surface of the inner groove is an inclined surface, and one end of the locking component is mounted inside the inner groove, rotating up and down around a pivot.

[0024] The beneficial effect of adopting the above-mentioned further solution is that one end of the locking component is rotated up and down around the pivot and is set in the inner groove, so that the other end of the locking component can be engaged or disengaged as the elastic element pushes the stabilizing column forward with different forces.

[0025] Furthermore, the end of the locking component that extends out of the inner groove has a hook, the end face of which has an arc-shaped structure, and the hook is engaged between the slider and the positioning buckle.

[0026] The beneficial effect of adopting the above-mentioned further solution is that one end of the locking component is set as a hook, and the end face of the hook is set as an arc, so that the hook can slide into the space between the slider and the positioning buckle through the top of the positioning buckle to lock the first fixing component and the second fixing component; or, the hook slides out from between the slider and the positioning buckle and slides towards the top face of the slider.

[0038] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0039] Example 1

[0040] like Figure 1-10As shown, an internal structure connection device for a sign body includes a first fixing member 1 and a second fixing member 2. The first fixing member 1 is disposed on the sign body frame, and the second fixing member 2 is disposed on the back panel of the electronic screen. The first fixing member 1 and the second fixing member 2 are connected in cooperation.

[0041] Specifically, the first fixing member 1 is set on the card frame, and the second fixing member 2 is set on the back panel of the electronic screen. Then, the back panel of the electronic screen is pressed, and the first fixing member 1 is pushed towards the second fixing member 2. The specific structure of the first fixing member 1 and the second fixing member 2 is used to realize the convenient connection between the back panel of the electronic screen and the card frame in the separated state and the snap-fit ​​state.

[0042] like Figure 1-10 As shown, the first fixing member 1 includes a first fixing platform 11, a slider 12, a positioning buckle 13, a stabilizing column 14, and an elastic member 15. The first fixing platform 11 is fixedly mounted on the card frame. A through hole is opened at one end of the first fixing platform 11 away from the card frame. The stabilizing column 14 and the elastic member 15 are disposed inside the first fixing platform 11. One end of the elastic member 15 is fixedly connected to the first fixing platform 11, and the other end of the elastic member 15 is fixedly connected to the bottom end of the stabilizing column 14. The other end of the stabilizing column 14 passes through the through hole. The slider 12 and the positioning buckle 13 are disposed opposite each other on the upper part of the first fixing platform 11. The second fixing member 2 is engaged between the slider 12 and the positioning buckle 13.

[0043] Specifically, the stabilizing column 14 and the elastic element 15 are sequentially arranged inside the first fixed platform 11. The elastic element 15 pushes the stabilizing column 14 to extend and slide, and by pushing the stabilizing column 14 to extend and slide, the second fixing element 2 is engaged or disengaged between the slider 12 and the positioning buckle 13.

[0044] like Figure 1-10 As shown, the stabilizing column 14 is a stepped structural component. The diameter of the stabilizing column 14 at one end through the through hole is smaller than the diameter at the other end, and the diameter at this end is smaller than the diameter of the through hole.

[0045] Specifically, the stabilizing column 14 is configured as a stepped structure. When the elastic element 15 pushes the stabilizing column 14 to extend and slide, the end of the stabilizing column 14 with a larger diameter abuts against the inner wall of the through hole, so that the end of the stabilizing column 14 with a smaller diameter abuts against the second fixing element 2. By pushing the stabilizing column 14 to extend and slide through the elastic element 15, the second fixing element 2 is engaged or disengaged between the slider 12 and the positioning buckle 13.

[0046] like Figure 1-10 As shown, the stabilizing column 14 is a telescopic structural component.

[0047] Specifically, the stabilizing column 14 is configured as a telescopic structural component. When the elastic element 15 pushes the stabilizing column 14 to extend and slide, it can reduce the expansion force and rebound force of the elastic element 15, thereby extending the service life of the elastic element 15 and the stabilizing column 14.

[0048] like Figure 1-10 As shown, the elastic element 15 is a spring.

[0049] Specifically, the elastic element 15 is set as a spring, so that the elastic element 15 has an expansion force and a rebound force, so that the elastic element 15 can act on the stabilizing column 14 according to its own elastic force, so that one end of the stabilizing column 14 abuts against the second fixing element 2.

[0050] like Figure 1-10 As shown, there is a gap between the slider 12 and the positioning buckle 13. The opposing sides of the slider 12 and the positioning buckle 13 are both inclined, and the two inclined surfaces are parallel.

[0051] Specifically, the two inclined surfaces between the slider 12 and the positioning buckle 13 are arranged in parallel. This allows the second fixing member 2 to be engaged or disengaged between the slider 12 and the positioning buckle 13.

[0052] like Figure 1-10 As shown, the top surface of the slider 12 and the top surface of the positioning buckle 13 are both inclined surfaces, and the ends of the slider 12 and the positioning buckle 13 that are opposite each other are higher than the other end.

[0053] Specifically, the top surfaces of both the slider 12 and the positioning buckle 13 are inclined surfaces. When the elastic element 15 pushes the stabilizing column 14 to extend and slide, the second fixing member 2 slides inclinedly into the gap between the slider 12 and the positioning buckle 13 along the top surface of the positioning buckle 13. When the elastic element 15 continues to push the stabilizing column 14 forward to extend and slide, the second fixing member 2 slides along the inclined surface in the gap of the slider 12 to the top and slides out along the top surface of the slider 12. This allows the second fixing member 2 to engage or disengage depending on the different forces with which the elastic element 15 pushes the stabilizing column 14 forward.

[0054] like Figure 1-10 As shown, the second fixing member 2 includes a second fixing platform 21, a locking member 22, and a rotating shaft 23. One side of the second fixing platform 21 has an inner groove 211. Both ends of the rotating shaft 23 are locked in the inner groove 211. One end of the locking member 22 is rotatably disposed in the inner groove 211 through the rotating shaft 23. The other end of the locking member 22 extends out of the inner groove 211 and is locked between the slider 12 and the positioning buckle 13.

[0055] Specifically, an inner groove 211 is opened on the second fixed platform 21, and one end of the locking member 22 is placed in the inner groove 211, while the other end of the locking member 22 extends out of the inner groove 211, so that the locking member 22 can be engaged or disengaged as the elastic member 15 pushes the stabilizing column 14 forward with different forces.

[0056] like Figure 1-10As shown, the upper surface of the inner groove 211 is an inclined surface, and one end of the locking member 22 is rotatably mounted in the inner groove 211 with the rotating shaft 23 as the axis.

[0057] Specifically, one end of the locking member 22 is rotated up and down around the pivot 23 and is located in the inner groove 211, so that the other end of the locking member 22 can be engaged or disengaged as the elastic member 15 pushes the stabilizing column 14 forward with different forces.

[0058] like Figure 1-10 As shown, the end of the locking member 22 that extends out of the inner groove 211 has a hook 221. The end face of the hook 221 is an arc-shaped structure. The hook 221 is locked between the slider 12 and the positioning buckle 13.

[0059] Specifically, one end of the locking member 22 is set as a hook 221, and the end face of the hook 221 is set as an arc shape, so that the hook 221 can slide into the slider 12 and the positioning buckle 13 through the top of the positioning buckle 13 to lock the first fixing member 1 and the second fixing member 2; or, the hook 221 slides out from between the slider 12 and the positioning buckle 13 and slides towards the top face of the slider 12.

[0060] The beneficial effects of this embodiment are: This device allows for convenient connection between the electronic screen back panel and the card frame, enabling both separation and engagement with a simple press. This simplifies construction, installation, maintenance, and repair procedures, reduces operation time, and improves the work efficiency of installation and maintenance personnel.

[0061] The working process of this embodiment is as follows: The first fixing member 1 is set on the back panel of the electronic screen, and the second fixing member 2 is set on the card frame. Then, the back panel of the electronic screen is pressed, and the first fixing member 1 is pushed towards the second fixing member 2. The elastic member 15 on the first fixing member 1 pushes the stabilizing column 14 to slide in the direction of the second fixing member 2. When the elastic member 15 is in a contracted state and is pushed back by the stabilizing column 14, the hook 221 slides out between the slider 12 and the positioning buckle 13 and slides towards the top surface of the slider 12. When the elastic member 15 is in an expanded state and pushes the stabilizing column 14 against the second fixing member 2, the hook 221 slides into the space between the slider 12 and the positioning buckle 13 through the top of the positioning buckle 13, forming a buckle with the slider 12 and the positioning buckle 13.

[0062] In this embodiment, this device is used to connect the electronic screen of the directional signage device to the internal frame of the sign. The overall frame of the signage has a double-sided, top-bottom structure, with a static lightbox signage module on top and a dynamic electronic screen on the bottom. Both the static and dynamic lightboxes are constructed with aluminum profiles and can be opened independently to over 60 degrees, meeting operational and maintenance requirements. The back panel of the dynamic electronic screen is connected to the frame using a snap-fit ​​connection via this device, allowing for quick installation and removal, and facilitating convenient maintenance during subsequent independent operation.
