A communication device schedules a terminal

Abstract

This utility model discloses a communication equipment dispatch terminal applied in the field of communication equipment. The protective frame and transparent protective plate together form a closed protective cover structure, allowing for a large gap between the protective frame and the display screen, preventing external objects from directly damaging the display screen. This provides sufficient deformation space for the protective frame. Simultaneously, the transparent protective plate overcomes the elasticity of the buffer spring upon impact, thus providing a good cushioning effect and offering excellent and comprehensive protection for the display screen with more stable protection. Furthermore, by designing the protective frame as a detachable and splicable frame composed of long and short side plates, if a particular long or short side plate is deformed or damaged by impact, the damaged long or short side plate can be replaced individually. Compared to replacing the entire protective frame, replacing individual plates reduces maintenance costs.

Description

Technical Field

[0001] This utility model relates to the field of communication equipment, and in particular to a communication equipment dispatch terminal. Background Technology

[0002] In fields such as industrial production, warehousing and logistics, and emergency rescue, communication equipment dispatch terminals are core devices for real-time information exchange, task scheduling, and equipment control. These terminals typically need to operate stably for extended periods in harsh environments with high dust levels, humidity, frequent vibrations, and even the risk of accidental drops or collisions.

[0003] Existing technology (patent document with publication number "CN214507553U") discloses a UAV three-dimensional emergency command and communication terminal dispatching device, including a housing, a protective plate, a fixing plate, and a limiting block. The exterior of the housing is connected to a lid via hinges, and the interior of the lid is connected to a display screen via an inlay. The interior of the lid contains a protective plate, and the fixing plate is fixedly connected inside the lid. The inner side of the fixing plate is connected to the protective plate via a slider. This UAV three-dimensional emergency command and communication terminal dispatching device, by incorporating a protective plate inside the lid, effectively solves the problem of poor protection for the internal display screen in traditional UAV command and communication terminal dispatching devices. During use, the protective plate can simply be moved to cover the display screen, thus achieving effective protection and effectively preventing damage from external objects. The overall structure is simple and highly practical.

[0004] Based on the above search and combined with existing technology, it was found that in order to prevent the display screen from being damaged when it is deformed by impact, the existing protective plates need to be set at intervals in front of the display screen. If the interval is too small, the protective plate may still damage the display screen when it is deformed. If the interval is too large, foreign objects may hit the display screen from the side. In addition, the protective plate is set horizontally, so it may detach from the fixed plates on both sides after impact deformation, resulting in poor protection reliability. Utility Model Content

[0005] 1. Technical problems to be solved

[0006] The core of this invention lies in solving the problem of unreliable protection for displays by protective plates in existing technologies through the combined use of a protective frame, a transparent protective plate, and a buffer spring. Furthermore, the modular design of the detachable protective frame reduces subsequent maintenance costs.

[0007] 2. Technical Solution

[0008] To solve the above problems, the present invention adopts the following technical solution.

[0009] A communication equipment dispatch terminal includes a box-type terminal body, a box cover hinged to the box-type terminal body, and a display screen fixed inside the box cover.

[0010] A ring-shaped protective frame is also fixed on the lid. The protective frame is fitted on the outside of the display screen, and there is a gap between the inner wall of the protective frame and the periphery of the display screen. An inwardly extending flange is formed at the end of the protective frame away from the lid. There is a gap between the extended flange and the front side of the display screen near the inner wall of the lid.

[0011] A transparent protective plate is slidably installed inside the protective frame. The periphery of the transparent protective plate slides against the inner wall of the protective frame. The side of the transparent protective plate near the cover is elastically connected to the cover by a buffer spring. The side of the transparent protective plate away from the cover abuts against the inner wall of the extended flange near the cover. There is a gap between the side wall of the transparent protective plate near the cover and the front side of the display screen.

[0012] The protective frame covers the perimeter of the display screen, and a transparent protective plate is installed on the inner side of the frame, forming a closed protective structure. This allows for a large gap between the protective frame and the display screen, preventing external objects from directly damaging the screen. It also provides sufficient deformation space for the protective frame. At the same time, the transparent protective plate will overcome the elasticity of the buffer spring when impacted, thus providing a good cushioning effect. This provides good and comprehensive protection for the display screen, and the protection effect is more stable.

[0013] Meanwhile, the transparent protective panel does not need to be moved repeatedly, allowing users to directly view the content of the display screen, making it more convenient to use.

[0014] Furthermore, the protective frame includes long side plates and short side plates fixed to the cover. Two long side plates are arranged in parallel on the upper and lower sides of the display screen, and two short side plates are also arranged in parallel on the left and right sides of the display screen. The two long side plates and the two short side plates are connected end to end to form a ring frame.

[0015] The transparent protective plate slides against the inner side of the long side plate and the inner side of the short side plate near the display screen. The inner side of the long side plate and the short side plate away from the cover is integrally formed with an extended flange. The outer side of the long side plate and the short side plate away from the display screen is integrally formed with a connecting ear. The connecting ear is fixed to the cover by bolts.

[0016] Furthermore, both the long and short side panels have integrally formed reinforcing guide ribs on their inner sides, which are perpendicular to the inner wall of the box cover. One end of the short side panel is integrally formed with the inner side of the extended flange.

[0017] The transparent protective plate has multiple grooves on its periphery, each groove corresponding to a reinforcing guide rib, and the reinforcing guide rib is slidably connected within the groove.

[0018] Furthermore, the end of the long side plate near the short side plate is integrally formed with a first protrusion and a concave portion, and the end of the short side plate near the long side plate is integrally formed with a second protrusion and a concave portion, and the first protrusion and the second protrusion and the concave portion are mutually engaged and adapted.

[0019] Preferably, a limiting ring is also fitted around the display screen. The limiting ring is annular and fixed to the inner wall of the cover. The inner sides of the long side plate and the short side plate near the display screen abut against the outer side of the limiting ring away from the display screen.

[0020] There is a gap between the limiting ring and the display screen. The distance between the side wall of the limiting ring away from the cover and the inner wall of the cover is greater than the distance between the front side of the display screen and the inner wall of the cover. The other end of the reinforcing guide rib extends to abut against the side of the limiting ring away from the cover.

[0021] Furthermore, an elastic ring is fixed to the side of the limiting ring away from the cover, and there is a gap between the elastic ring and the side of the transparent protective plate closer to the display screen.

[0022] 3. Beneficial effects

[0023] Compared with existing technologies, the advantages of this utility model are:

[0024] (1) This solution forms a closed protective cover structure by combining the protective frame and the transparent protective plate, so that there is a large gap between the protective frame and the display screen and no external object can directly damage the display screen, thus leaving enough deformation space for the protective frame. At the same time, when the transparent protective plate is impacted, it will overcome the elasticity of the buffer spring and thus play a good buffering effect, providing a good and comprehensive protection effect for the display screen, and the protection effect is more stable.

[0025] (2) This solution designs the protective frame as a detachable frame composed of long side plates and short side plates. When a long side plate or a short side plate is deformed or damaged by impact, the damaged long side plate or short side plate can be replaced separately. Compared with replacing the entire protective frame, replacing separately reduces maintenance costs.

[0026] (3) This solution uses a limiting ring to facilitate the installation of long and short side plates. By placing the long and short side plates against the outside of the limiting ring, the long and short side plates can be positioned to assist in the installation. At the same time, it can further enhance the impact resistance of the long and short side plates and improve their protective effect.

[0027] It can also limit the sliding stroke of the transparent protective plate when it is impacted and slides, so that the transparent protective plate stops moving towards the display screen when it slides and presses against the limit ring, thereby reducing the probability of the transparent protective plate hitting the display screen and causing damage to the display screen, and even avoiding the transparent protective plate hitting the display screen, thus achieving a good secondary protection effect.

Detailed Implementation

[0034] The technical solution will now be clearly and completely described with reference to the accompanying drawings in the embodiments of this utility model.

[0035] Example 1:

[0036] Please see Figures 1-3 A communication equipment dispatch terminal includes a box-type terminal body 1, a box cover 2 hinged to the box-type terminal body 1, and a display screen 3 fixed inside the box cover 2. The box-type terminal body 1 includes a box body excluding the box cover 2 and a terminal body. Its specific structure is consistent with the structure disclosed in the prior art (i.e., the box body, equipment body and other structures in the prior art). The working principle, connection relationship, layout, communication, circuit principle and other aspects are all prior art, and will not be described in detail here.

[0037] A ring-shaped protective frame 4 is also fixed on the cover 2. The protective frame 4 is fitted on the outside of the display screen 3, and there is a gap between the inner wall of the protective frame 4 and the periphery of the display screen 3. An inwardly extending flange 43 is formed at the end of the protective frame 4 away from the cover 2. There is a gap between the extended flange 43 near the inner wall of the cover 2 and the front side of the display screen 3.

[0038] A transparent protective plate 5 (made of explosion-proof glass, with good light transmission and explosion-proof performance, and not easily damaged by impact) is slidably installed inside the protective frame 4. The transparent protective plate 5 slides and fits against the inner wall of the protective frame 4. The side of the transparent protective plate 5 near the cover 2 is elastically connected to the cover 2 by a buffer spring 6 (the buffer spring 6 is a compression spring). The side of the transparent protective plate 5 away from the cover 2 abuts against the inner wall of the extended flange 43 near the cover 2. There is a gap between the side wall of the transparent protective plate 5 near the cover 2 and the front side of the display screen 3.

[0039] Based on the above structure, the annular protective frame 4 can cover the periphery of the display screen 3. The protective frame 4 and the transparent protective plate 5 together form a closed protective cover structure, which allows for a large gap between the protective frame 4 and the display screen 3, and prevents external objects from directly damaging the display screen 3. This provides sufficient deformation space for the protective frame 4. At the same time, when the transparent protective plate 5 is impacted, it will overcome the elasticity of the buffer spring 6 and contract, thus achieving a good buffering effect. This provides good and comprehensive protection for the display screen 3, and the protection effect is more stable.

[0040] Meanwhile, the transparent protective plate 5 does not need to be moved repeatedly, allowing users to directly view the content of the display screen 3, making it more convenient to use.

[0041] Furthermore, the protective frame 4 includes a long side plate 41 and a short side plate 42 fixed to the cover 2. The long side plate 41 is provided with two parallel distributions on the upper and lower sides of the display screen 3, and the short side plate 42 is also provided with two parallel distributions on the left and right sides of the display screen 3. The two long side plates 41 and the two short side plates 42 are connected end to end to form an annular frame.

[0042] The transparent protective plate 5 slides and abuts against the inner side of the long side plate 41 and the inner side of the short side plate 42 near the display screen 3. The inner side of the long side plate 41 and the short side plate 42 away from the cover 2 are integrally formed with an extended flange 43. The outer side of the long side plate 41 and the short side plate 42 away from the display screen 3 are integrally formed with a connecting ear 45. The connecting ear 45 is fixed to the cover 2 by bolts.

[0043] By designing the protective frame 4 as a detachable frame composed of a long side plate 41 and a short side plate 42, when a long side plate 41 or a short side plate 42 is deformed or damaged by impact, the damaged long side plate 41 or short side plate 42 can be replaced individually. Compared with replacing the entire protective frame 4, individual replacement reduces maintenance costs.

[0044] Furthermore, both the long side plate 41 and the short side plate 42 have an integrally formed reinforcing guide rib 44 on their inner sides. The reinforcing guide rib 44 is set perpendicular to the inner wall of the box cover 2. One end of the short side plate 42 is integrally formed with the inner side of the extended flange 43.

[0045] The transparent protective plate has multiple grooves 51 on its periphery, and each groove 51 corresponds to a multiple reinforcing guide rib 44, and the reinforcing guide rib 44 is slidably connected in the groove 51.

[0046] The reinforcing guide rib 44 strengthens the structure of the long side plate 41 and the short side plate 42, making them more impact-resistant and reducing the probability of deformation and damage, thereby further reducing maintenance costs. At the same time, it can also work with the slide groove 51 to limit the transparent protective plate 5, allowing the transparent protective plate 5 to slide in a predetermined direction, preventing the transparent protective plate 5 from tilting when impacted, ensuring good cooperation between the transparent protective plate 5 and the buffer spring 6, and ensuring the buffering effect.

[0047] Furthermore, to enhance the connection stability between the long side plate 41 and the short side plate 42 and reduce the probability of gaps arising from deformation after impact, a first protrusion-concave portion 46 is integrally formed at the end of the long side plate 41 near the short side plate 42, and a second protrusion-concave portion 47 is integrally formed at the end of the short side plate 42 near the long side plate 41. The first protrusion-concave portion 46 and the second protrusion-concave portion 47 are mutually engaged and adapted, thereby making the long side plate 41 and the short side plate 42 more tightly connected. This reduces the probability of gaps arising from deformation of the long side plate 41 and the short side plate 42 due to impact, further improving the stability and reliability of the protective frame 4 in protecting the display screen 3.

[0048] Example 2:

[0049] Please see Figure 2 and Figure 4 A communication equipment scheduling terminal, this embodiment is based on embodiment 1, the difference between this embodiment and embodiment 1 is:

[0050] The display screen 3 is also fitted with a limiting ring 7 around its perimeter. The limiting ring 7 is annular and fixed to the inner wall of the cover 2. The inner sides of the long side plate 41 and the short side plate 42 near the display screen 3 abut against the outer side of the limiting ring 7 away from the display screen 3.

[0051] There is a gap between the limiting ring 7 and the display screen 3. The distance between the side wall of the limiting ring 7 away from the cover 2 and the inner wall of the cover 2 is greater than the distance between the front side of the display screen 3 and the inner wall of the cover 2. The other end of the reinforcing guide rib 44 extends to abut against the side of the limiting ring 7 away from the cover 2.

[0052] Meanwhile, an elastic ring 8 is fixed on the side of the limiting ring 7 away from the cover 2. The elastic ring 8 is made of a flexible elastic material commonly used in the prior art and applicable to this embodiment, such as rubber or silicone. There is a gap between the elastic ring 8 and the side of the transparent protective plate 5 near the display screen 3.

[0053] By setting the limiting ring 7, when installing the long side plate 41 and the short side plate 42, the long side plate 41 and the short side plate 42 are abutted against the outside of the limiting ring 7, which can play an auxiliary positioning role in the installation of the long side plate 41 and the short side plate 42. At the same time, it can further enhance the impact resistance of the long side plate 41 and the short side plate 42 and improve their protective effect.

[0054] It can also limit the sliding stroke of the transparent protective plate 5 when it is impacted and slides, so that the transparent protective plate 5 stops moving towards the display screen 3 when it slides and presses against the limit ring 7, thereby reducing the probability of the transparent protective plate 5 hitting the display screen 3 and causing damage to the display screen 3, and even preventing the transparent protective plate 5 from hitting the display screen 3 and playing a good secondary protection effect.

[0055] In addition, the elastic ring 8 can also transform the impact between the transparent protective plate 5 and the limiting ring 7 from a rigid device into a flexible impact, which can provide good protection for the limiting ring 7 and the transparent protective plate 5 and extend their service life.

[0056] The above description is merely a preferred embodiment of this utility model; it encompasses all the protection scope of this utility model. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be covered within the protection scope of this utility model.
