Description

Technical Field

[0001] This utility model relates to the field of electronic equipment technology, and in particular to a conductive quick-release device for electronic price tags. Background Technology

[0002] In the retail industry, electronic price tags are used for price management, replacing manual replacement of paper price tags. Because they save time and effort, they are an effective tool for refined management and are gradually being promoted and applied in the retail industry.

[0003] Currently, most electronic shelf labels on the market adopt a rotating design. This involves setting a fixed metal plate on the main body of the electronic shelf label, which is rotated to contact the power supply wire in the power supply rail, thereby powering and installing the electronic shelf label. When the position of the electronic shelf label needs to be adjusted, it needs to be rotated off the power supply rail and then rotated off again for installation. The installation and disassembly efficiency is low. In addition, the rotating installation method requires a reserved rotation radius, which means that there must be a gap between the electronic shelf labels. This makes it difficult to set the position of the electronic shelf labels according to actual needs, and the existing quick-release devices are too wide. Utility Model Content

[0004] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a conductive quick-release device for electronic price tags.

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

[0006] A conductive quick-release device for electronic price tags, installed on a power supply slide rail, includes:

[0007] The housing is slidably connected to the power supply slide rail;

[0008] A conductive module, which is electrically connected to an electronic price tag; and

[0009] At least one pressing mechanism is movably installed within one end of the housing, and an elastic element abutting against the pressing mechanism is provided within one end of the housing. The pressing mechanism includes a pressing member and two sliders. One of the pressing member and sliders has a connecting protrusion, and the other has a connecting groove. The connecting protrusion and the connecting groove are slidably connected and engaged with each other. The two connecting grooves are arranged sequentially along the pressing direction of the pressing member, and their projections in the pressing direction at least partially overlap. When the pressing member is pressed, the connecting protrusion and the connecting groove are driven to slide relative to each other, so that the slider is in a first state of being disengaged from the power supply slide rail. When the pressing member is released, the elastic element resets, so that the slider is in a second state of being engaged with the power supply slide rail.

[0010] Furthermore, the pressing member is provided with two connecting grooves, and the two sliders have a first position and a second position when sliding relative to the connecting grooves. When the two sliders are in the first position, they are in a first state, and when the two sliders are in the second position, they are in a second state. The distance between the first position and the elastic member is greater than the distance between the second position and the elastic member.

[0011] Furthermore, the two connecting grooves are arranged in a figure-eight or V-shape.

[0012] Furthermore, each of the two sliders is provided with a connecting protrusion, and the two connecting protrusions are slidably connected to the two connecting grooves respectively.

[0013] Furthermore, a button extends from one end of the pressing member, and the button protrudes beyond the end of the housing.

[0014] Furthermore, the housing has mounting cavities at both ends, and the pressing member is slidably connected to the mounting cavity; the elastic member is installed in the mounting cavity, with one end of the elastic member abutting against the pressing mechanism and the other end abutting against the bottom wall of the mounting cavity.

[0015] Furthermore, the housing has openings on both sides for the slider to extend out; the portion of the slider extending out of the opening has a guide slope, which is positioned towards the top of the housing.

[0016] Furthermore, the bottom ends of the housing are fastened with covers, the covers are provided with limiting grooves, the limiting grooves are perpendicular to the axial direction of the housing, and the slider slides along the limiting grooves.

[0017] Furthermore, the side wall of the housing is provided with a first mounting hole, and the cover is provided with a corresponding limiting protrusion, which is engaged in the first mounting hole.

[0018] Furthermore, the conductive module includes a conductive sheet, and the housing is provided with a second mounting hole. The conductive sheet protrudes from the second mounting hole, and during operation, power is supplied through the contact between the conductive sheet and the power supply rail.

[0019] The beneficial effects of this utility model are:

[0020] 1. The present invention proposes a conductive quick-release device for electronic price tags, which reduces the width of the housing by arranging connecting grooves sequentially along the pressing direction of the pressing component, and the projections in the pressing direction at least partially overlap, thereby adapting to the installation of ultra-thin electronic price tags.

[0021] 2. The present invention proposes an electronic price tag conductive quick-release device, which, by pressing the button extended by the pressing member, causes the inclined structure of the connecting groove to move the slider from the first position to the second position of the connecting groove, thereby realizing the slider disengaging from the power supply slide rail for disassembly; after releasing, the elastic member pushes the pressing member to reset, and the slider moves from the second position to the first position of the connecting groove, thereby realizing the slider engaging with the power supply slide rail.

[0022] 3. The present invention proposes an electronic price tag conductive quick-release device, which sets up a slider, with the slider part exposed outside the housing and set with a guide slope. The guide slope automatically corrects the positional deviation between the slider and the slide rail slot during installation, and can be directly snapped into the power supply slide rail without pressing the buttons at both ends.

[0023] 4. The present invention proposes an electronic price tag conductive quick-release device, which includes a cover with a limiting groove perpendicular to the axial direction of the housing, restricting the slider to move only along the axial direction of the limiting groove; the cover is fixedly engaged with the first mounting hole on the side wall of the housing through a limiting protrusion.

[0024] 5. This utility model proposes a conductive quick-release device for electronic price tags. By incorporating a conductive module, it achieves tight contact with the conductive contacts of the power supply slide rail during installation, thus powering the electronic price tag. During the sliding process of the housing, the conductive sheet maintains elastic contact with the slide rail, ensuring stable power supply. Attached Figure Description

Detailed Implementation

[0037] The following is combined Figure 1-10 This utility model will be described in detail.

[0038] A conductive quick-release device for electronic price tags, installed on a power supply slide rail, such as... Figure 1-2 As shown, including

[0039] Housing 10, which is slidably connected to the power supply slide rail;

[0040] A conductive module, which is electrically connected to an electronic price tag; and

[0041] At least one pressing mechanism is movably installed in one end of the housing 10, and an elastic member 40 abutting the pressing mechanism is provided in one end of the housing 10. The pressing mechanism includes a pressing member 20 and two sliders 30. One of the pressing member 20 and the slider 30 is provided with a connecting protrusion 301, and the other is provided with a connecting groove 201. The connecting protrusion 301 and the connecting groove 201 are slidably connected and engaged with each other. The two connecting grooves 201 are arranged sequentially along the pressing direction of the pressing member 20 and their projections in the pressing direction at least partially overlap.

[0042] When the pressing member 20 is pressed, the drive connecting protrusion 301 slides relative to the connecting groove 201, so that the slider 30 is in the first state of being disengaged from the power supply slide rail; when the pressing member 20 is released, the elastic member 40 resets, so that the slider 30 is in the second state of being engaged with the power supply slide rail.

[0043] Specifically, pressing mechanisms are movably installed at both ends of the housing 10; the projections of the two connecting grooves 201 in the pressing direction completely overlap.

[0044] like Figure 3-6 As shown, when the pressing mechanism is pressed, the pressing member 20 drives the two sliders 30 to slide along the connecting groove 201. The two sliders 30 retract into the opening 101 until they are separated from the housing 10, so that the sliders 30 are in the first state of being separated from the power supply slide rail. At this time, the elastic member 40 is in the compressed state. When the pressing mechanism is released, the elastic member 40 resets and drives the pressing member 20 to move outward. The two sliders 30 slide back along the connecting groove 201 and reset. One end of the two sliders 30 extends out of the opening 101, so that the sliders 30 are in the second state of being engaged with the power supply slide rail.

[0045] In this embodiment, the pressing member 20 is provided with two connecting grooves 201. When the two sliders 30 slide relative to the connecting grooves 201, they have a first position and a second position. When the two sliders 30 are in the first position, they are in the first state; when the two sliders 30 are in the second position, they are in the second state. The distance between the first position and the elastic member 40 is greater than the distance between the second position and the elastic member 40. It should be noted that the two connecting grooves 201 can be separate or connected. The shape of the two connecting grooves 201 can be straight or curved. In this embodiment, the two connecting grooves 201 are arranged in a figure-eight shape. Specifically, the two connecting grooves 201 form an angle with each other, and the extending direction of the connecting grooves 201 is neither parallel nor perpendicular to the pressing direction of the pressing member 20.

[0046] In this embodiment, as Figure 8 As shown, each of the two sliders 30 is provided with a connecting protrusion 301, which is slidably connected to two connecting grooves 201. The two sliders 30 are embedded in the connecting grooves 201 through the connecting protrusions 301 and can slide along the grooves. The two sliders 30 are placed on both sides of the pressing member 20 and are staggered to avoid motion interference. Each slider 30 corresponds to an obliquely set connecting groove 201. The first groove and the second groove are obliquely set, so that when the pressing member 20 slides, it drives the slider 30 to slide.

[0047] In this embodiment, as Figure 7As shown, a button 202 extends from one end of the pressing member 20, and the button 202 extends beyond the end of the housing 10. The button 202 extends from one end of the pressing member 20 and protrudes from the end face of the housing 10 to facilitate user pressure; the other end is provided with two connecting grooves 201 arranged in a "V" shape.

[0048] When button 202 is pressed, pressing member 20 compresses elastic member 40 inward, and two sliders 30 retract towards the center of housing 10 along the two V-shaped connecting grooves 201, so that the protruding part is disengaged from the power supply slide rail slot; after being released, elastic member 40 pushes pressing member 20 to reset, and sliders 30 expand outward along connecting grooves 201 to reset, and re-lock slide rail.

[0049] In this embodiment, the housing 10 has mounting cavities 104 at both ends, and the pressing member 20 is slidably connected to the mounting cavity 104; the elastic member 40 is installed in the mounting cavity 104, one end of the elastic member 40 abuts against the pressing mechanism, and the other end abuts against the bottom wall of the mounting cavity 104, providing a reset elastic force for pressing.

[0050] In this embodiment, the housing 10 has openings 101 on both sides for the slider 30 to extend out, and the slider 30 is partially exposed outside the housing 10 through the openings 101. The openings 101 are located on both sides of the housing 10 and are staggered along the axial direction of the housing 10. When the slider 30 is not pressed, it extends out of the openings 101 to engage with the power supply slide rail. The portion of the slider 30 extending out of the openings 101 is provided with a guide slope 302, which faces the top of the housing 10. The partially exposed slider 30, with the exposed end having a guide slope 302 facing the top of the housing 10, facilitates automatic guidance and positioning when aligned with the slot of the power supply slide rail, and facilitates alignment with the slide rail and smooth engagement during installation.

[0051] In this embodiment, as Figure 9 As shown, cover bodies 50 are fastened to the bottom of both ends of the housing 10. The cover body 50 is provided with a limiting groove 501, which is perpendicular to the axial direction of the housing 10. The slider 30 slides along the limiting groove 501. The axial direction of the limiting groove 501 is perpendicular to the axial direction of the housing 10, which restricts the slider 30 to move only along the limiting groove 501.

[0052] In this embodiment, the side wall of the housing 10 is also provided with a first mounting hole 102, and the cover 50 is correspondingly provided with a matching limiting protrusion 502, which is engaged in the first mounting hole 102. The cover 50 is engaged and fixed to the first mounting hole 102 on the side wall of the housing 10 by the limiting protrusion 502. After the cover 50 is fastened, its limiting groove 501 restricts the slider 30 to slide only along the axial direction of the limiting groove 501, preventing displacement. When fastened, the limiting protrusion 502 engages with the first mounting hole 102, enhancing the connection stability between the cover 50 and the housing 10.

[0053] In this embodiment, as Figure 10As shown, the conductive module includes a conductive sheet 60, and a second mounting hole 103 is provided on the housing 10. The conductive sheet 60 protrudes from the second mounting hole 103. During operation, the conductive sheet 60 contacts the power supply rail to achieve power supply.

[0054] Specifically, the conductive sheet 60 includes a base plate 601 and an arc-shaped spring piece 602 connected to each other. The base plate 601 is installed inside the housing 10, and the arc-shaped spring piece 602 is partially exposed through the second mounting hole 103 at the top of the housing 10. During installation, the arc-shaped spring piece 602 makes close contact with the conductive contacts of the power supply slide rail. The conductive sheet 60 is made of an elastic metal material, such as phosphor bronze, to ensure stable contact pressure and avoid the risk of power failure. The arc-shaped spring piece 602 protrudes from the second mounting hole 103 of the housing 10 and makes close contact with the conductive contacts of the power supply slide rail during installation, thus enabling power supply to the electronic price tag. During the sliding process of the housing 10, the conductive sheet 60 always maintains elastic contact with the slide rail to ensure stable power supply.

[0055] The present invention provides a conductive quick-release device for electronic price tags, the method of which is as follows:

[0056] During installation and disassembly, first align the screw holes on the electronic price tag body with the threaded holes on the housing 10. Then, insert screws into the corresponding through holes on the top of the housing 10 and tighten them to fix the housing 10 to the electronic price tag. At this time, the positive and negative terminals of the electronic price tag's PO GO PIN are electrically connected to the conductive sheet 60. Next, align the power supply rail and apply a pushing force to the housing 10. The guide slope 302 will cause the slider 30 to retract inward, and the pressing member 20 will move outward under the elasticity of the spring. The connecting groove 201 will press the connecting protrusion 301, causing the movable block to lock the power supply rail, preventing the housing 10 from detaching from the power supply rail. After the housing 10 and the power supply rail are installed, the conductive sheet 60 will contact the power supply rail to conduct electricity. When it is necessary to remove the device from the power supply rail, apply a pushing force to the pressing member 20 to retract the slider 30 inward, thereby easily detaching the housing 10 from the installation position on the power supply rail, achieving quick installation and disassembly of the electronic price tag.

[0057] This device reduces the width of the housing 10 by sequentially arranging connecting grooves 201 along the pressing direction on the pressing member 20, with their projections in the pressing direction at least partially overlapping, thereby adapting to the installation of ultra-thin electronic price tags.

[0058] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the scope of protection of this utility model.
