Description

Technical Field

[0001] This utility model relates to the field of constant temperature and humidity cabinet technology, specifically a constant temperature and humidity cabinet that is easy to debug. Background Technology

[0002] A control cabinet is an assembly of switching equipment, measuring instruments, protective devices, and auxiliary equipment in a closed or semi-closed metal cabinet or panel according to electrical wiring requirements. Its layout should meet the requirements for normal operation of the power system, facilitate maintenance, and not endanger personnel or surrounding equipment. During normal operation, circuits can be connected or disconnected manually or automatically. In case of faults or abnormal operation, protective devices can cut off the circuit or trigger an alarm. Measuring instruments can display various operating parameters and allow adjustment of certain electrical parameters. Deviations from normal operating conditions can be alerted or signaled. Air conditioning constant temperature and humidity control cabinets are one type of control cabinet.

[0003] As disclosed in the patent announcement CN219937625U, a temperature and humidity control cabinet that is easy to debug includes a cabinet body, a first support plate, a second support plate, a third support plate, a limiting shaft, a limiting mechanism, and a connecting mechanism. The second support plate is located below the first support plate, and the third support plate is located below the second support plate. The beneficial effects of this utility model are: the third support plate is fixed by the limiting pin, which is more convenient than adjusting multiple mounting plates separately, effectively improving the efficiency of pre-debugging operations.

[0004] Although the aforementioned patent includes a linkage mechanism and a limiting mechanism, the limiting mechanism relies on the elastic force of the connecting spring to push the limiting pin into the groove of the limiting shaft to achieve fixation. This is a "flexible" or "elastic" limiting mechanism, rather than a "rigid" locking mechanism. After long-term use, the connecting spring may weaken due to metal fatigue, causing the limiting pin to fail to fully eject or to not engage tightly with the groove. Even slight vibrations or impacts to the cabinet may cause the limiting pin to come out of the groove, resulting in the bearing plate sliding unexpectedly and failing to provide a stable and reliable platform for precise debugging work. Utility Model Content

[0005] The purpose of this invention is to provide a constant temperature and humidity cabinet that is easy to debug, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A temperature and humidity control cabinet that is easy to adjust, including

[0008] The cabinet has several support plates arranged from top to bottom inside, and a positioning mechanism is provided between the support plates and the back of the cabinet.

[0009] A sliding frame is symmetrically arranged at both ends of the support plate, and an installation mechanism is provided between the sliding frame and the support plate.

[0010] Preferably, the positioning mechanism includes a number of insertion holes evenly distributed from top to bottom on the inner side of the back of the cabinet, and a movable hole that passes through the middle of the support plate. An insertion rod is slidably connected inside the movable hole. A telescopic groove is provided in the middle of the side of the support plate away from the insertion holes. One end of the insertion rod extends into the telescopic groove and is fixedly connected to a pull handle.

[0011] Preferably, the positioning mechanism further includes a limiting groove formed on the side of the movable hole near the telescopic groove, and a limiting plate fixedly connected to the outer periphery of the insertion rod and slidingly engaged with the limiting groove. A spring is movably sleeved on the outside of the insertion rod, and the two ends of the spring abut against the limiting plate and the limiting groove, respectively.

[0012] Preferably, the positioning mechanism further includes a fixing groove symmetrically opened at the middle of both ends of the telescopic groove, and a fixing block symmetrically fixedly connected to the middle of the outer sides of both ends of the pull handle and matching the fixing groove. A locking screw is threadedly connected to the middle of the fixing block, and a locking hole matching the locking screw is opened in the middle of the inner side of the fixing groove.

[0013] Preferably, the installation mechanism includes guide grooves symmetrically opened at both ends of the bearing plate, and guide bars fixedly connected to one end of the two sliding frames facing each other. A positioning frame is fixedly connected to the front of the guide bar. A rotating block is rotatably connected to the side of the sliding frame near the positioning frame through a rotating shaft. A positioning screw is threadedly connected to the middle of the positioning frame. A positioning hole matching the positioning screw is opened at the end of the rotating block away from the rotating shaft.

[0014] Preferably, vertical guide rods are fixedly connected to the four internal corners of the cabinet, and bushings that slide and engage with the guide rods are fixedly connected to both ends of the sliding frame. A cabinet door is hinged to the front of the cabinet.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This type of temperature and humidity control cabinet, which is easy to debug, provides rigid mechanical locking based on the initial locking of the spring by using the pull handle, fixing block and locking screw in conjunction with the fixing groove and locking hole. This effectively solves the problems of unreliable locking caused by spring fatigue or vibration due to pure elastic limit and the easy accidental sliding of the bearing plate.

[0017] 2. This easy-to-adjust constant temperature and humidity cabinet, through the cooperation of several evenly distributed sockets on the back of the cabinet and the positioning mechanism on the support plate, allows the installation spacing between multiple sets of support plates to be flexibly adjusted non-equidistantly according to actual debugging needs, based on the fixed spacing of the sockets. This effectively solves the problem that the spacing between support plates in the prior art can only be adjusted at a fixed equidistant distance and cannot adapt to the layout requirements of equipment of different sizes, greatly improving the flexibility and practicality of the internal space layout of the cabinet.

[0024] 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.

[0025] like Figure 1-5 As shown, this utility model provides a technical solution:

[0026] A temperature and humidity control cabinet that is easy to adjust includes a cabinet body 1, inside which several support plates 2 are arranged sequentially from top to bottom. A positioning mechanism is provided between the support plates 2 and the back of the cabinet body 1. The positioning mechanism includes several insertion holes 4 evenly distributed from top to bottom on the inner side of the back of the cabinet body 1, and a movable hole 5 penetrating the middle of the support plate 2. An insertion rod 6 is slidably connected inside the movable hole 5. A telescopic groove 7 is opened in the middle of the side of the support plate 2 away from the insertion holes 4. One end of the insertion rod 6 extends into the telescopic groove 7 and is fixedly connected to a pull handle 8. The positioning mechanism also includes a limiting groove 9 opened in the side of the movable hole 5 near the telescopic groove 7, and a limiting plate 10 fixedly connected to the outer periphery of the insertion rod 6 and slidingly cooperating with the limiting groove 9. A spring 11 is movably sleeved on the outside of the insertion rod 6. The two ends of the spring 11 abut against the limiting plate 10 and the limiting groove 9, respectively. The positioning mechanism further includes a fixing groove 12 symmetrically opened in the middle of both ends of the telescopic groove 7, and a fixing groove 12 symmetrically fixedly connected to the middle of the outer sides of both ends of the pull handle 8. A fixing block 13, matching the fixing groove 12, has a locking screw 14 threadedly connected to its center. A locking hole 15, matching the locking screw 14, is provided in the center of the inner side of the fixing groove 12. Sliding brackets 3 are symmetrically arranged at both ends of the support plate 2. An installation mechanism is provided between the sliding brackets 3 and the support plate 2. The installation mechanism includes guide grooves 16 symmetrically opened at both ends of the support plate 2, and guide bars 17 fixedly connected to the opposing ends of the two sliding brackets 3. The front of the guide bar 17... A positioning frame 18 is fixedly connected. A rotating block 19 is rotatably connected to the side of the sliding frame 3 near the positioning frame 18 via a rotating shaft. A positioning screw 20 is threadedly connected to the middle of the positioning frame 18. A positioning hole 21 matching the positioning screw 20 is opened at the end of the rotating block 19 away from the rotating shaft. Vertical guide rods 22 are fixedly connected to the four corners inside the cabinet 1. Both ends of the sliding frame 3 are fixedly connected to bushings 23 that slide and engage with the guide rods 22. A cabinet door 24 is hinged to the front of the cabinet 1.

[0027] In this embodiment, by pulling the handle 8, fixing block 13 and locking screw 14 in conjunction with fixing groove 12 and locking hole 15, a rigid mechanical locking is provided on the basis of the initial locking of spring 11, which effectively solves the problems of unreliable locking caused by fatigue or vibration of spring 11 and easy accidental sliding of bearing plate 2 due to pure elastic limit.

[0028] Furthermore, by using the combination of several evenly distributed sockets 4 on the back of the cabinet 1 and the positioning mechanism on the support plate 2, the installation spacing between multiple sets of support plates 2 can be flexibly adjusted non-equidistantly according to actual debugging needs, based on the fixed spacing of the sockets 4. This effectively solves the problem that the spacing between the support plates 2 can only be adjusted at a fixed equidistant distance in the existing technology and cannot adapt to the layout requirements of equipment of different sizes, greatly improving the flexibility and practicality of the internal space layout of the cabinet 1.

[0029] Working principle: When it is necessary to pull the support plate 2 out of the cabinet 1, first loosen the positioning screw 20 on the positioning bracket 18 so that it exits from the positioning hole 21 of the rotating block 19. Then, rotate the rotating block 19 upward around its axis of rotation. At this time, the connection between the support plate 2 and the sliding bracket 3 is released. The operator can then pull the support plate 2 to slide it outward along the guide groove 16 via the guide bar 17, thereby pulling the support plate 2 out of the cabinet 1 as a whole for adjustment or maintenance. When it is necessary to adjust the height of the support plate 2 in the cabinet 1, the operator first loosens the locking screw 14 on the fixing block 13 so that it exits from the locking hole 15 of the fixing groove 12, and then pulls the handle 8 outward. Pull handle 8 to compress spring 11 and move it into telescopic groove 7, so that the other end of plug rod 6 exits from the currently locked insertion hole 4 on the back of cabinet 1. At this time, the support plate 2 is in the unlocked state, and the operator can move the support plate 2 up and down, driving the sliding frame 3 to slide along guide rod 22 through bushing 23. After the support plate 2 moves to the required height, release pull handle 8. Under the restoring force of spring 11, plug rod 6 is automatically pushed into insertion hole 4 corresponding to the height to achieve initial positioning. At the same time, pull handle 8 to simultaneously lock the fixing blocks 13 at both ends into fixing groove 12. Finally, tighten locking screw 14 to insert it into locking hole 15, thus completing the fixing and locking of the height of support plate 2.

[0030] It should be noted that in the specific implementation of this technical solution, the existing patent CN212114396U, "An Air Conditioning Constant Temperature and Humidity Control Cabinet that is Easy to Debug," discloses the cabinet 1 proposed in this application. The cabinet 1 in this application adopts the same technical means as the prior art, and both can achieve constant temperature and humidity control. These technical means will not be described in detail here.
