Description

Technical Field

[0001] This utility model relates to the field of industrial control display technology, and in particular to an industrial control display with built-in device signal indicator lights. Background Technology

[0002] Industrial control displays, as key human-machine interfaces in the field of industrial automation, are widely used in various mechanical equipment and production lines to display important information such as equipment operating status, process parameters, and fault alarms in real time. In order to intuitively and quickly convey critical status signals, such as "running," "stopping," or "faulting," these displays typically integrate one or more equipment signal indicator lights on their outer casing.

[0003] In existing technical solutions, these built-in indicator lights are typically mounted on the housing using threaded fasteners. Specifically, maintenance personnel need to tighten the indicator light sockets from inside the housing using nuts, or use screws to secure the sockets to the panel. Similarly, the entire industrial control display module itself, when installed in a control cabinet or machine, generally uses multiple screw holes in the frame for securing with multiple screws. This traditional screw and nut-based fixing method does ensure a strong and reliable connection, performing well in static use.

[0004] However, industrial environments are complex, and equipment is constantly subjected to vibration and temperature fluctuations. Indicator lights, as frequently used electronic components, are prone to damage or reaching the end of their lifespan. When an indicator light needs replacement, the inherent limitations of the maintenance process become apparent. Maintenance personnel not only need to stop the equipment, but also need to carry specific tools and typically must first remove the entire display module from the equipment or open the control cabinet to access the inside of the display casing and loosen nuts or screws to replace the light. This series of operations is cumbersome and time-consuming.

[0005] Furthermore, the problem becomes even more pronounced when the main screen or internal circuitry of the industrial control monitor malfunctions and requires complete replacement. Maintenance personnel must loosen all the screws securing the monitor module one by one, and then, after replacement, retighten them all. This process is not only inefficient but also particularly inconvenient in confined installation environments. In modern industrial production, which prioritizes high efficiency and low downtime, this excessively long maintenance time due to structural design has become a critical technical challenge that urgently needs to be addressed. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides an industrial control display with built-in device signal indicator lights, aiming to improve the problems of cumbersome and time-consuming replacement of signal indicator lights due to screw fixing, and the inconvenience of assembly and disassembly of the entire display module due to screw fixing.

[0007] To achieve the above objectives, the present invention provides the following technical solution: an industrial control display with built-in device signal indicator lights, comprising: a housing, a display screen disposed on the housing, and a light assembly mechanism; and a quick-release assembly for locking the housing.

[0008] The lamp assembly mechanism has an electrode post and a fixing post with a locking groove on the outer wall. The outer shell is movably provided with a locking tongue that can be driven by a first spring. The quick-release assembly has a locking post with teeth arranged along its length and a gear that meshes with the teeth.

[0009] Furthermore, the lamp assembly mechanism is combined by engaging the locking groove on its fixing post with the spring-driven locking tongue located inside the housing, while its electrode post is inserted into the electrode socket on the housing; the quick-release assembly is combined by engaging the gear with the teeth on the locking post to control the extension and retraction of the locking post.

[0010] Preferably, the lamp assembly mechanism further includes a lamp head, and both the electrode post and the fixing post are connected to the lamp head.

[0011] Preferably, the locking tongues are configured as a pair and symmetrically arranged on both sides of the insertion path of the fixing post, and the first spring is used to be squeezed by the locking tongues when the fixing post is inserted.

[0012] Preferably, the gear is fixedly mounted on the rotating column, which is rotatably mounted on the outer casing.

[0013] Preferably, the teeth of the locking pin are arranged along its length to form a rack structure that meshes with the gear for transmission.

[0014] Preferably, the quick-release assembly further includes a handle, which is fixedly connected to the end of the rotating column.

[0015] Preferably, the quick-release assembly further includes a knob coaxially disposed with the handle, which is also connected to the rotating column.

[0016] Preferably, the quick-release assembly further includes a second spring, which is sleeved on the outer wall of the rotating column to provide a reset torque.

[0017] Preferably, the end of the fixing post is configured as a guide structure for displacing the locking tongue during insertion.

[0018] Preferably, the locking tongue protrudes from the inner wall of the housing under the elastic force of the first spring and engages in the locking groove to achieve locking.

[0019] This utility model has the following beneficial effects:

[0020] 1. In this utility model, by setting up a lamp assembly mechanism, the lamp assembly mechanism is provided with a locking groove that engages with the elastic locking tongue on the inner wall of the outer shell. The principle of elastic buckle is used to realize the quick plug-in connection between the lamp assembly mechanism and the outer shell, which solves the problems of difficulty in replacing damaged signal indicator lights, the need to disassemble the entire display panel, and the time and effort required in the prior art. It achieves the effect of plug-and-play signal indicator lights, quick replacement, reduced maintenance difficulty and downtime.

[0021] 2. In this utility model, by setting up a quick-release component, the operating handle drives the gear to mesh with the teeth on the locking pin, controlling the extension or retraction of the locking pin, thereby realizing the quick locking and separation of the entire display module from the machine equipment. This solves the problem that industrial control display modules are usually fixed with screws in the prior art, and the installation and disassembly process is cumbersome and inefficient. It achieves the effect of quickly installing and disassembling the entire display module without tools, greatly improving the speed of maintenance and replacement. Attached Figure Description

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please refer to Figures 1 to 6 This utility model provides an industrial control display with built-in device signal indicator lights, which aims to solve the problems of difficult maintenance and replacement of signal indicator lights and long overall disassembly and assembly time in the prior art.

[0032] like Figure 1 and Figure 2 As shown, the industrial control display of the built-in device signal indicator includes a housing 1 as an overall frame, a display screen 2 fixedly mounted on the housing 1, and a lamp assembly mechanism 3 detachably mounted on the housing 1.

[0033] Reference Figure 3 and Figure 5 The lamp assembly mechanism 3 includes a lamp head 301, an electrode post 302 and a fixing post 305 extending from the lamp head 301. The outer wall of the fixing post 305 is provided with a locking groove 303 for engaging. The end of the fixing post 305 is configured as a guide structure for squeezing the locking tongue 306 during insertion to cause it to move. The outer shell 1 is provided with an electrode socket 304 for inserting the electrode post 302. The locking tongue 306 is movably provided on the inner wall of the outer shell 1. Further, the locking tongue 306 is provided as a pair, symmetrically arranged on both sides of the insertion path of the fixing post 305. The outer shell 1 is also provided with a spring 307. The spring 307 is squeezed by the locking tongue 306 when the fixing post 305 is inserted. When the locking groove 303 on the fixing post 305 moves to the position of the locking tongue 306, the elastic force of the spring 307 pushes the locking tongue 306 to protrude and engage in the locking groove 303, thereby realizing the detachable fixed connection between the lamp assembly mechanism 3 and the outer shell 1.

[0034] Reference Figure 4 and Figure 6A quick-release assembly 4 for locking the entire industrial control display module is mounted on the housing 1. The quick-release assembly 4 includes a locking pin 401 that can slide linearly on the housing 1 to lock or unlock. The locking pin 401 has teeth 402 arranged along its length to form a rack structure. The quick-release assembly 4 also includes a gear 405 that meshes with the teeth 402. The gear 405 is fixedly mounted on a rotating pin 403, which is rotatably mounted on the housing 1. A handle 404 for user operation is fixedly connected to the end of the rotating pin 403. A knob 407 coaxially mounted with the handle 404 is also connected to the rotating pin 403. A spring 406 is sleeved on the outer wall of the rotating pin 403 to provide a reset torque to the rotating pin 403 after the handle 404 is released, thereby causing the locking pin 401 to extend and automatically lock through the transmission of the gear 405 and the teeth 402.

[0035] In a preferred embodiment, the lamp assembly mechanism 3 further includes a lamp head 301, with the electrode post 302 and the fixing post 305 integrally connected to the lamp head 301, forming a module that is easy to insert and remove as a whole; the tapered end of the fixing post 305 is configured as a guide structure to smoothly squeeze the locking tongue 306 to retract to both sides during insertion into the housing 1; more specifically, the locking tongue 306 is configured as a symmetrical pair, which protrude from the inner wall of the housing 1 under the elastic force of the spring 307, so that when the fixing post 305 is inserted into place, it can reliably be locked into the locking groove 303 to achieve stable locking.

[0036] In another preferred embodiment, the transmission structure of the quick-release assembly 4 is further defined. The teeth 402 on the locking pin 401 are continuously arranged along its linear motion direction, forming a rack structure that meshes with the gear 405 on the rotating pin 403, thereby accurately converting the rotational motion into linear motion. To facilitate the application of torque, the handle 404 is fixedly connected to the end of the rotating pin 403. At the same time, the knob 407, which is coaxially arranged with the handle 404, is also connected to the rotating pin 403, providing another mode of operation. The spring 406 used to achieve automatic locking is a torsion spring, which is sleeved on the outer wall of the rotating pin 403. One end of the spring is fixed to the outer shell 1, and the other end is fixed to the rotating pin 403, thereby providing a reset torque when the handle 404 is released.

[0037] Working principle: First, install the entire industrial control display module. The operator rotates the rotating column 403 by rotating handle 404. The rotating column 403 drives the gear 405 to rotate. The gear 405 meshes with the teeth 402 on the locking column 401, driving the locking column 401 to retract inward. Then, place the industrial control display module in the preset installation position on the machine. Release handle 404. The return torque of spring 406 drives the rotating column 403 to rotate in the opposite direction, thereby causing the locking column 401 to extend and engage with the corresponding hole on the machine to complete the locking. Then, install the lamp assembly. To install mechanism 3, align the electrode post 302 and the fixing post 305 of the lamp assembly mechanism 3 with the electrode socket 304 and the mounting groove on the outer casing 1, and press down. The guide end of the fixing post 305 will press the locking tongue 306. When the locking groove 303 on the fixing post 305 reaches the position of the locking tongue 306, the spring 307 will push the locking tongue 306 into the locking groove 303 to achieve fixation. When disassembling, the process is the reverse of installation. The entire module can be removed by retracting the locking post 401 through the operating handle 404. To replace the lamp assembly mechanism 3, it is only necessary to overcome the locking force of the locking tongue 306 and pull it out.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
