Description

Technical Field

[0001] The present invention relates to the field of industrial technology, and in particular to a display cabinet for displaying some electronic control products such as relays. Background Art

[0002] With the rapid development of the industrial sector, electronic control products such as relays are playing a critical role across a wide range of industries. In addition to their use in industrial control, they are also widely used in wind power, machine tools, home appliances, new energy, packaging and woodworking machinery, photovoltaics, and other fields. When promoting and demonstrating these electronic control products to customers, engineers often present these products individually, failing to clearly demonstrate the relay's functions and specific application scenarios. Furthermore, at exhibitions, relays are used in some large equipment, but their functionality cannot be clearly displayed on these large equipment. Furthermore, they are not portable, making it difficult to present the products directly to customers.

[0003] Furthermore, while existing display cabinets can control the on / off operation of relays, these use a circuit board mounted inside the cabinet, with relays attached to the board via guide rails. The relays' on / off operation is controlled by an external voltage input. When a button is pressed, all relays begin operating, and when the button is pressed, the relays stop operating. When displaying these display cabinets, customers can only determine the relays' operating status by observing the on / off indicator lights on the relays, providing no intuitive understanding of the relays' operating principles or application scenarios.

[0004] Therefore, it is necessary to design a new type of display cabinet to realize the functional display of the product, attract customers' attention through different functional displays, and facilitate customers to receive product information more intuitively, while also facilitating portable use during promotion. Summary of the Invention

[0008] Furthermore, the inner cavity of the cabinet is divided into a first inner cavity and a second inner cavity arranged up and down. The rotating display mechanism is installed in the first inner cavity, the switching display mechanism is installed on the side of the second inner cavity close to the observation side, and the control mechanism is installed on the side away from the observation side.

[0009] Furthermore, the control mechanism is a PLC controller, the inner cavity is divided into a first inner cavity and a second inner cavity by a partition, and the PLC controller is fixedly mounted on the partition.

[0010] Furthermore, the rotating display mechanism includes a plurality of shaft wheels and a rotating device. The front side of the shaft wheel facing the observation side has a fixing portion for fixing the electronic control product. The rotating device drives each shaft wheel to rotate through a gear set.

[0011] Furthermore, the cabinet body also has a panel arranged facing the observation side, the panel has multiple hollow parts, each hollow part is equipped with an axle wheel, and the rotating device and gear set are arranged in the space on one side of the panel away from the observation side.

[0012] Furthermore, each hollow portion of the panel is equipped with a decorative ring buckle, and the fixing portion of the shaft wheel is located in the hollow area in the middle of the decorative ring buckle.

[0013] Furthermore, the rotating device is a motor, and the gear set includes multiple first gears and multiple second gears.

[0025] To further illustrate various embodiments, the present invention is provided with accompanying drawings. These drawings form part of the present disclosure and are primarily used to illustrate the embodiments and, in conjunction with the relevant description in the specification, to explain the operating principles of the embodiments. By referring to these drawings, one of ordinary skill in the art will understand other possible embodiments and the advantages of the present invention. The components in the figures are not drawn to scale, and similar reference numerals are generally used to represent similar components.

[0026] The present invention will now be further described with reference to the accompanying drawings and specific embodiments.

[0027] The present invention provides a display cabinet, which is mainly used for displaying some electronic control products. In this embodiment, a relay is used as an example for explanation, but it is not limited to this. It can also be used to display other electronic control products, such as vacuum switches, circuit breakers, etc.

[0028] like Figures 1-6 As shown, a display cabinet provided in this embodiment includes a cabinet body 1 having an inner cavity 10 , and a rotating display mechanism 2 , a switching display mechanism 3 and a control mechanism 4 installed in the inner cavity of the cabinet body 1 .

[0029] The cabinet 1 in this embodiment is a roughly rectangular hollow structure. The front of the cabinet 1 serves as the viewing side of the inner cavity 10. A transparent cabinet door 11, such as a glass door, may be installed on the viewing side. This allows the inner cavity 10 inside the cabinet 1 to be viewed while also protecting the products and mechanisms inside the cabinet and providing dust protection. The cabinet door 11 can be opened by sliding or rotating. The bottom of the cabinet 1 is equipped with multiple bases 12. The bases 12 may be fixed support legs or wheels to facilitate the movement of the cabinet 1.

[0030] A buckle 13 may also be provided on the side of the cabinet 1 for easy transportation of the cabinet. A drawer 14 may also be provided at the bottom of the cabinet 1 for storing tools or spare parts.

[0031] The inner cavity 10 of the cabinet body 1 is divided into a first inner cavity 101 and a second inner cavity 102 arranged in two layers, upper and lower, by a partition 103. A rotating display mechanism 2 is installed in the first inner cavity 101, and a switching display mechanism 3 and a control mechanism 4 are installed in the second inner cavity 102. The switching display mechanism 3 is installed on the side of the second inner cavity 102 close to the cabinet door, and the control mechanism 4 is installed on the side of the second inner cavity 102 away from the cabinet door.

[0032] The rotating display mechanism 2 includes multiple shaft wheels 23 on a panel 21 located in front of the first inner chamber 101, and a rotating device 22 mounted on the rear side of the first inner chamber 101. The panel 21 has multiple hollow sections 210, each of which houses a shaft wheel 23. The front of the shaft wheel 23 faces the cabinet door, and the front of the wheel axle has a fixing portion 230 for securing the relay 6. The rotating device 22 drives each shaft wheel 23 via a gear set 24, thereby rotating the relay attached to the shaft wheel 23, thereby facilitating the display of the relay. The panel 21 also has a button switch 5 that controls the operation of the rotating display mechanism 2 and the control mechanism 4.

[0033] Specifically, the rotating device 22 is a motor, and the gear set 24 includes multiple first gears 241 and multiple second gears 242. The multiple first gears 241 are arranged in a one-to-one correspondence with the multiple shaft wheels 23, and each first gear 241 is coaxially connected to the corresponding shaft wheel 23. The second gear 242 is located between two adjacent first gears 241 and is meshed with the two adjacent first gears 241. The rotor of the motor serving as the rotating device 22 is driven and connected to one of the first gears 241 or the second gear 242 to drive one of the gears to rotate, thereby driving the other gears to rotate, and finally driving the shaft wheel 23 to rotate, and the speed of the shaft wheel 23 can be adjusted by the number of teeth of the first gear and the second gear.

[0034] In this embodiment, each hollow portion is further equipped with a decorative ring buckle 25. The fixing portion 230 of the shaft wheel 23 is located in the hollow area in the middle of the decorative ring buckle 25. The decorative ring buckle 25 can cover the hollow portion 210 on the panel 21 to provide a better visual effect of the panel 21. When the relay 6 is fixed to the shaft wheel 23, the decorative ring buckle 25 can make the relay 6 more prominent, more easily attracting the visitor's attention to the relay. The decorative ring buckle 25 can also be equipped with LED lamp beads or LED light strips to serve as an ambient light for the relay 6 installed in the decorative ring buckle 25, further highlighting the displayed product.

[0035] The switching display mechanism 3 in this embodiment includes multiple first relay groups 31 and multiple second relay groups 32, wherein the first relay groups 31 are installed on a guide rail 310 fixed in the cabinet, and the second relay groups 32 are installed on a circuit board 320 fixed in the cabinet, so that visitors can simultaneously watch the switching actions of the relay groups in different application scenarios and have a more intuitive understanding of their working process and state switching.

[0036] The control mechanism 4 includes at least one controller, which is fixedly installed in the cabinet. The first relay group 31, the second relay group 32 and the motor are connected to the controller through a wire 33. The controller can be a controller in the prior art that can control the working state of an electronically controlled product, such as a PLC controller. In this embodiment, the controller is also described as a PLC controller. Figure 6 The PLC controller shown in the figure only shows some chip devices for illustration purposes; other electrical components are not shown. The number of PLC controllers can be one or more. For example, multiple PLC controllers can be used to control the operation of the first relay group, the second relay group, and the motor respectively. Alternatively, there can be only one PLC controller, with a master PLC controller used to simultaneously control the operation of the first relay group, the second relay group, and the motor. The PLC controller is directly fixedly mounted on the partition 103, eliminating the need to add other components for mounting the PLC controller on the second inner cavity 102, thereby simplifying the structure of the display cabinet.

[0037] When the PLC control unit is powered on, the relay groups can be switched in a certain order by pressing a button. For example, in this embodiment, the first relay groups 31 are divided into three groups, mounted on the guide rail 310 from left to right. When the button is pressed, the three first relay groups 31 switch in sequence from left to right. When the first relay group 31 in the third group switches, the signal is fed back to the PLC control unit, and the PLC control unit outputs a signal, repeating the switching action of the three first relay groups 31. This allows visitors to intuitively understand the relay switching process.

[0038] In this embodiment, an LED panel 7 is also installed on the front side of the top of the inner cavity 10. A plurality of LED lamp beads are arranged on the LED panel, and these LED lamp beads have at least two colors. For example, the LED panel in this embodiment has a plurality of green LED lamp beads and a plurality of red LEDs. The LED lamp beads on the LED panel 7 are directed toward the relay 6 on the shaft wheel 23, the first relay group 31 on the guide rail, and the second relay group 32 on the circuit board, so as to play the role of lighting and highlighting. In addition, the LED lamp beads of different colors on the LED panel 7 can switch to different colors according to the different states of the relay group. For example, when the two button switches 5 are pressed at the same time, the SMD LED lamp beads switch between red and green lights, and the lighting of the red light and the front end motion display area of ​​the upper part present the same tooling state, that is, the red light is on and the three shaft wheels 23 rotate. When the red light is off and the green light is on, the relay group and the PLC controller in the lower part interact with each other, thereby showing the customer the overall control loop solution and product function interaction solution.

[0039] The circuit principle diagram of the control mechanism 4 of this embodiment controlling the rotating display mechanism 2, the switching display mechanism 3 and the LED panel 7 can be found in Figure 7 .

[0040] The display cabinet provided in this embodiment can realize an intuitive display of the product, its working status, control loop solution and product function interaction solution through the display mechanism and control mechanism, which can more effectively enable customers to understand and accept the application information of the product in the shortest time, and facilitate the seller's promotion of the product.

[0041] Although the present invention has been particularly shown and described in conjunction with preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made to the present invention without departing from the spirit and scope of the invention as defined in the appended claims, and all such changes are within the scope of protection of the present invention.
