Description

Technical Field

[0001] This utility model belongs to the field of agricultural monitoring equipment technology, and in particular relates to a temperature and humidity detector for seedling rooms. Background Technology

[0002] Seedling raising is a key link in agricultural production. Temperature and humidity are core environmental factors that affect seedling germination, growth and stress resistance. Their precise control is directly related to seedling quality and subsequent crop yield. In the current technology, temperature and humidity monitoring in seedling rooms mainly relies on temperature and humidity detectors.

[0003] To improve the space utilization efficiency of seedling nurseries and achieve intensive seedling cultivation, current seedling nurseries adopt multi-layered, three-dimensional frame structures with seedling trays placed vertically to optimize space allocation and increase the seedling yield per unit area. For accurate data monitoring, temperature and humidity sensors need to be installed on the frame where the seedling trays are placed. Traditionally, installing these sensors requires drilling holes in the frame and fixing them with screws. However, these holes cannot be repaired after disassembly, and re-drilling is necessary to adjust the sensor's position. These installation holes can damage the frame structure and compromise its overall strength. Therefore, a temperature and humidity sensor for seedling nurseries that can be installed without drilling is needed. Utility Model Content

[0004] The purpose of this invention is to clamp the frame by the cooperation of the extrusion member and the clamping plate, so that the instrument body can be installed without drilling holes in the frame. This solves the problem in the background art that the installation of traditional temperature and humidity detectors requires drilling holes in the frame, but the installation holes cannot be repaired after disassembly, and the installation holes will cause damage to the frame structure and destroy the overall strength of the frame.

[0005] The specific technical solution of this utility model is as follows:

[0006] A temperature and humidity detector for a seedling room includes a detector body with a support connected to its bottom. A clamping plate is vertically arranged at the lower rear side of the support, with one side of the clamping plate fixedly connected to the support. A shaft is horizontally arranged at the lower front side of the support, with one end of the shaft fixedly connected to the support. The shaft and the clamping plate are positioned opposite each other. An extrusion component is rotatably connected to the shaft. The extrusion component is cylindrical, and its end face has a shaft through hole adapted to the shaft. The extrusion component is rotatably connected to the shaft through the shaft through hole. The shaft through hole is offset from the central axis of the extrusion component and close to the circumferential surface of the extrusion component. An operating rod is fixedly connected to the circumferential surface of the extrusion component, and the operating rod is perpendicular to the central axis of the extrusion component.

[0007] Furthermore, the extruded part is made of rubber.

[0008] Furthermore, a limiting component is provided at the end of the shaft away from the bracket. The limiting component is a cylinder, and its outer diameter is larger than the inner diameter of the shaft through hole.

[0009] Furthermore, the front surface of the plywood is provided with anti-slip texture.

[0010] Furthermore, an adjustment component is connected to the upper part of the bracket, and the adjustment component is connected to the main body of the detector. The bracket is provided with an assembly hole one, and the adjustment component is provided with an assembly hole two that matches the assembly hole one. The bracket and the adjustment component are connected through the cooperation of the assembly hole one, the assembly hole two, and the bolt and nut assembly one.

[0011] Furthermore, the upper part of the adjusting component is provided with a mounting through hole, and an adjusting rod is installed in the mounting through hole. One end of the adjusting rod is connected to the main body of the detector.

[0012] Furthermore, a connecting rod is vertically installed at one end of the adjusting rod, and a limit post is installed at the top of the connecting rod. The limit post is cylindrical, and a limit groove is provided at the bottom of the detector body housing to match the limit post. The detector body achieves rotational connection with the connecting rod through the cooperation of the limit groove and the limit post.

[0013] Furthermore, the top of the adjusting component is provided with an opening groove, the bottom of which is connected to the mounting through hole. The two sides of the adjusting component are provided with three mounting holes, and bolt and nut assembly two is installed in the three mounting holes.

[0014] Furthermore, the adjusting component is provided with an arc-shaped slide groove located below the second mounting hole, and the bracket is provided with a fourth mounting hole that matches the arc-shaped slide groove. Fasteners are provided in both the arc-shaped slide groove and the fourth mounting hole.

[0015] Furthermore, the fastener is a bolt and nut assembly two, with a screwing tool provided on the top of the bolt.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] When installing the temperature and humidity detector, rotate the extruder so that the side of it closest to the shaft through hole is opposite the clamping plate. At this time, the gap between the clamping plate and the extruder is the largest. Place the uprights or beams of the frame into the gap between the clamping plate and the extruder. Rotate the extruder again. At this time, the side of the extruder away from the shaft through hole gradually moves closer to the clamping plate, and the gap between the clamping plate and the extruder becomes smaller. Clamp the uprights or beams of the frame and install the temperature and humidity detector on the frame. The installation process is simple and does not require drilling holes in the frame, so it will not affect the overall strength of the frame. Attached Figure Description

[0033] To better understand the purpose, structure, and function of this utility model, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0034] In the description of this utility model, it should be understood that the terms "upper," "lower," "front," "rear," "top," and "bottom," etc., indicate the orientation or positional relationship based on the appendix. Figure 1 The orientations or positional relationships shown are for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0035] See Figures 1 to 8 This embodiment discloses a temperature and humidity detector for a seedling room, including a detector body 1. The detector body 1 is a temperature and humidity detector. The connection method and function of the electronic components inside the detector body 1 can adopt existing technologies and solutions. A bracket 2 is connected to the bottom of the detector body 1. A clamping plate 21 is vertically arranged on the lower rear side of the bracket 2. One side of the clamping plate 21 is fixedly connected to the bracket 2. A shaft 22 is horizontally arranged on the lower front side of the bracket 2. One end of the shaft 22 is fixedly connected to the bracket 2. The shaft 22 is arranged opposite to the clamping plate 21. An extrusion member 3 is rotatably connected to the shaft 22. The extrusion member 3 is a cylinder. The end face of the extrusion member 3 is provided with a shaft through hole 31 adapted to the shaft 22. The extrusion member 3 achieves rotatable connection with the shaft 22 through the shaft through hole 31 and the shaft 22. The shaft through hole 31 is offset from the central axis of the extrusion member 3 and close to the circumferential surface of the extrusion member 3. Therefore, the extrusion member 3 has a side close to the shaft through hole 31 and a side far away from the shaft through hole 31. On one side of the shaft through hole 31, an operating rod 32 is fixedly connected to the circumferential surface of the extrusion part 3. The operating rod 32 is perpendicular to the central axis of the extrusion part 3. The extrusion part 3 can be easily rotated through the operating rod 32. When installing the temperature and humidity detector, rotate the extrusion part 3 so that the side of it close to the shaft through hole 31 is opposite to the clamping plate 21. At this time, the gap between the clamping plate 21 and the extrusion part 3 is the largest. Place the upright or crossbeam of the frame into the gap between the clamping plate 21 and the extrusion part 3. Rotate the extrusion part 3 again. At this time, the side of the extrusion part 3 away from the shaft through hole 31 gradually moves closer to the clamping plate 21. The gap between the clamping plate 21 and the extrusion part 3 becomes smaller. Clamp the upright or crossbeam of the frame and install the temperature and humidity detector on the frame. When disassembling the temperature and humidity detector, rotate the extrusion part 3 so that the side of the extrusion part 3 away from the shaft through hole 31 gradually moves away from the clamping plate 21. The gap between the clamping plate 21 and the extrusion part 3 becomes larger. The temperature and humidity detector can then be removed from the frame.

[0036] The extrusion part 3 is made of rubber, which has elasticity and friction. The elasticity causes the extrusion part 3 to gradually extrude the frame away from the shaft through hole 31, resulting in elastic deformation. This allows the extrusion part 3 and the clamping plate 21 to clamp the frame more tightly. The increased friction increases the friction between the extrusion part 3 and the frame, further increasing the clamping force of the extrusion part 3 and the clamping plate 21 on the frame.

[0037] A limiting member 221 is provided at the end of the shaft 22 away from the bracket 2. The limiting member 221 is a cylinder and its outer diameter is larger than the inner diameter of the shaft through hole 31. The limiting member 221 prevents the extruded part 3 from falling off the shaft 22.

[0038] The front surface of the clamping plate 21 is provided with anti-slip texture 211, which increases the friction between the clamping plate 21 and the frame, and further increases the clamping force of the extrusion piece 3 and the clamping plate 21 on the frame.

[0039] An adjusting component 4 is connected to the upper part of the bracket 2. The adjusting component 4 is connected to the detector body 1. The bracket 2 is provided with a first mounting hole 23, and the adjusting component 4 is provided with a second mounting hole 41 that matches the first mounting hole 23. The bracket 2 and the adjusting component 4 are rotatably connected through the cooperation of the first mounting hole 23, the second mounting hole 41 and the bolt and nut assembly. By adjusting the angle between the adjusting component 4 and the bracket 2, the operating angle of the detector body 1 can be adjusted, which increases the flexibility of the temperature and humidity detector.

[0040] The upper part of the adjusting component 4 is provided with a mounting through hole 42, and an adjusting rod 5 is provided in the mounting through hole 42. One end of the adjusting rod 5 is connected to the detector body 1. By adjusting the position of the adjusting rod 5 in the mounting through hole 42, the usage position of the detector body 1 can be adjusted, which increases the flexibility of the temperature and humidity detector.

[0041] One end of the adjusting rod 5 is vertically provided with a connecting rod 51, and the top of the connecting rod 51 is provided with a limiting post 511. The limiting post 511 is a cylinder. The bottom of the housing of the detector body 1 is provided with a limiting groove 11 that matches the limiting post 511. The detector body 1 achieves a rotatable connection with the connecting rod 51 through the cooperation of the limiting groove 11 and the limiting post 511, which can adjust the operating angle of the detector body 1.

[0042] The top of the adjusting component 4 is provided with an opening groove 43, the bottom of which is connected to the mounting through hole 42. The two sides of the adjusting component 4 are provided with mounting holes 3 44 facing each other. The mounting holes 3 44 are equipped with bolt and nut assembly 2. By tightening the bolt and nut assembly 2, the groove distance of the opening groove 43 is reduced, so that the mounting through hole 42 tightly clamps the connecting rod 51, increasing the stability of the detector body 1 during use.

[0043] The adjusting component 4 is provided with an arc-shaped slide groove 45, which is located below the second mounting hole 41. The bracket 2 is provided with a fourth mounting hole 24 that matches the arc-shaped slide groove 45. Fasteners 6 are provided in both the arc-shaped slide groove 45 and the fourth mounting hole 24. By cooperating with the arc-shaped slide groove 45, the fourth mounting hole 24, and the fasteners 6, the operating angle of the detector body 1 can be adjusted. After the angle is adjusted, the fasteners 6 are tightened to increase the stability of the detector body 1 during use.

[0044] Fastener 6 is a bolt and nut assembly two, with a screwing part 61 on the top of the bolt for easy screwing operation.

[0045] Working principle: When installing the temperature and humidity detector, rotate the pressing component 3 so that the side of it closest to the shaft through hole 31 is opposite to the clamping plate 21. At this time, the gap between the clamping plate 21 and the pressing component 3 is at its maximum. Place the uprights or crossbeams of the frame into the gap between the clamping plate 21 and the pressing component 3. Rotate the pressing component 3 again. At this time, the side of the pressing component 3 away from the shaft through hole 31 gradually moves closer to the clamping plate 21, and the gap between the clamping plate 21 and the pressing component 3 becomes smaller. This clamps the uprights or crossbeams of the frame, and the temperature and humidity detector is installed on the frame. When disassembling the temperature and humidity detector, rotate the pressing component 3 so that the side of the pressing component 3 away from the shaft through hole 31 gradually moves away from the clamping plate 21, and the gap between the clamping plate 21 and the pressing component 3 becomes larger. The temperature and humidity detector can then be removed from the frame. The installation and disassembly process is simple to operate, does not require drilling holes in the frame, and leaves no installation marks after disassembly, and does not affect the overall strength of the frame.

[0046] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and concept of the present utility model, should be included within the protection scope of the present utility model.
