AI Technical Summary
[0002]现有的台式光谱仪，在激发台处的前机罩都是采用铰接形式，即前机罩的底部通过铰链板与台式光谱仪的机箱底部连接，前机罩利用螺钉锁紧，前机罩与机箱之间还有一根拉线连接，当需要打开前机罩时，拧松螺钉后即可向外打开，方便于观察内部结构，但是实际检修过程中仍然存在不便，特别是要更换零部件时，前机罩会影响操作，而拆卸前机罩时需要先将铰链板拆除或者将拉线拆除，操作麻烦，影响了检修效率
[0005]采用本实用新型后，当前机罩需要打开时，松开锁紧螺钉，然后前机罩可以向前打开，利用卡条与支撑板的配合，倒V形槽开入卡槽内且卡条支撑在卡槽的斜面上，可以让前机罩处于倾斜开启状态，卡条和支撑板之间可以随时分离，将前机罩向上移走，让机箱的前部露出，方便于进行检修。

Abstract
Description
Technical Field
[0001] This utility model relates to the field of spectrometer technology, specifically to a spectrometer front cover structure. Background Technology
[0002] Existing benchtop spectrometers typically use a hinged design for the front cover at the excitation stage. The bottom of the front cover is connected to the bottom of the spectrometer chassis via a hinge plate, and the cover is secured with screws. A cable connects the front cover to the chassis. To open the front cover, simply loosen the screws, allowing for easy observation of the internal structure. However, this design still presents inconveniences during actual maintenance, especially when replacing parts. The front cover can interfere with operation, and disassembling it requires removing the hinge plate or the cable, which is cumbersome and reduces maintenance efficiency. Summary of the Invention
[0003] To solve the above-mentioned technical problems, this utility model provides a spectrometer front cover structure that can be easily opened and is convenient for maintenance.
[0004] The technical solution is as follows: a spectrometer front cover structure, including a chassis and a front cover, wherein locking screws are respectively installed on both sides of the upper front of the chassis, and threaded holes that mate with the locking screws are opened on both sides of the upper front of the front cover. The characteristic is that support seats are respectively installed on both sides of the bottom front of the chassis, and each support seat is provided with two support plates. The support plates are provided with slots, the front end of the slots is inclined and the rear end is vertical. The bottom of the front cover is provided with a retaining strip, and the retaining strip is provided with an inverted V-shaped groove that mates with the retaining groove.
[0005] With this invention, when the front cover needs to be opened, the locking screws are loosened, and the front cover can be opened forward. By using the cooperation of the locking strip and the support plate, the inverted V-shaped groove is opened into the locking slot, and the locking strip is supported on the inclined surface of the locking slot, which allows the front cover to be in an inclined opening state. The locking strip and the support plate can be separated at any time, and the front cover can be moved upward to expose the front of the chassis, which is convenient for maintenance. Attached Figure Description
[0006] Figure 1 This is a schematic diagram of the front cover of this utility model in the closed state; Figure 2 This is a schematic diagram of the front hood of this utility model in the open state; Figure 3 This is a schematic diagram of the front hood structure; Figure 4 This is a schematic diagram of the support bracket on the chassis; Figure 5 This is a side view of the support base. Detailed Implementation
[0007] See Figures 1 to 5 As shown, a spectrometer front cover structure includes a housing 1 and a front cover 2. Locking screws 3 are installed on both sides of the upper front of the housing 1. Threaded holes 4 that mate with the locking screws 3 are opened on both sides of the upper part of the front cover 2. Support seats 5 are installed on both sides of the bottom front of the housing 1. The support seats 5 are U-shaped seats, forming two support plates 6 on both sides. The support plates 6 have slots 7. The front end of the slots 7 is inclined and the rear end is vertical. The bottom of the front cover 2 is provided with a retaining strip 8. The retaining strip 8 has an inverted V-shaped groove 9 that mates with the retaining groove 7.
[0008] After the front cover 2 is flipped up and closed, screw the locking screw 3 into the threaded hole. With the retaining strip 8 vertical, let the inverted V-shaped groove 9 engage with the retaining groove 7 to fix the front cover 2 in place. When it is necessary to open the front cover 2, loosen the locking screw 3, lift the front cover slightly, and it can be opened outward. The inverted V-shaped groove 9 is still in the retaining groove 7 until the retaining strip 8 contacts the inclined surface of the retaining groove 7, providing support. The front cover 2 is now in the open state. When it is necessary to remove the front cover 2, simply lift it up to separate the retaining strip 8 from the support plate 6, and then remove the front cover.
[0009] If there is a connecting wire between the front cover 2 and the chassis 1, after the clip 8 and the support plate 6 are separated, the front cover 2 can still be lifted up or moved to the sides and can still be moved away from the front of the chassis 1 without affecting maintenance.
Claims
1. A spectrometer front cover structure, comprising a chassis and a front cover, wherein locking screws are respectively installed on both sides of the upper front end of the chassis, and threaded holes for cooperating with the locking screws are provided on both sides of the upper part of the front cover, characterized in that, Support bases are installed on both sides of the front bottom of the chassis. Each support base has two support plates. The support plates have slots with a beveled front end and a vertical rear end.
