Description

Technical Field

[0001] This utility model relates to the field of electronic equipment technology, and in particular to a fastening structure and electronic equipment. Background Technology

[0002] Electronic devices are composed of electronic components such as integrated circuits and transistors, and use electronic technology (including software) to achieve specific functions. The basic components of electronic devices include three major elements: electronic components, with integrated circuits, transistors, vacuum tubes and other basic components; technical support, which relies on electronic technology to achieve functions, including hardware circuit design and software control; and function realization, which completes specific tasks through power conversion, signal processing or information control.

[0003] With the advancement of technology, smart home devices are becoming increasingly widespread. For these devices to operate properly, sensors need to be installed in various locations within the house to monitor factors such as temperature and humidity. This data then feeds back to the system to control temperature-regulating equipment like air conditioners. However, existing sensors are mostly fixed directly to walls or other base surfaces using bolts or other fasteners. This makes maintenance difficult, requiring the removal of multiple bolts for disassembly and subsequent reinstallation, which is laborious and inconvenient. Therefore, we propose a new fastening structure and electronic device. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned shortcomings in the existing technology by proposing a fastening structure and electronic device.

The second sleeve is threaded into the screw hole.

[0013] Preferably, the present invention also includes an electronic device, including a housing, which is a perforated housing with grooves on the surface. A sensor module and a controller are disposed inside the housing. The controller is connected to the sensor module via wires. The sensor module includes a temperature sensor and a humidity sensor.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Example

[0025] Reference Figures 1-5A fastening structure and electronic device include a strip plate 1, which is vertically arranged. At least two spaced-apart strip grooves 2 are formed on the strip plate 1, extending along its length. U-shaped frames 3 are located at both ends of one side of the strip plate 1, with their openings close to the strip plate 1, meaning the strip plate 1 is placed within the U-shaped frames 3. At least two connecting posts 4 are installed inside the U-shaped frames 3, and connecting shafts 5 are installed at the other ends of the connecting posts 4. The connecting shafts 5 pass through the strip grooves 2 and connect to limiting plates 6. The limiting plates 6 correspond one-to-one with the U-shaped frames 3. In actual use, the limiting plates 6 and the strip plate 1 are fitted with a clearance fit. The diameter of the connecting posts 4 is greater than the width of the strip grooves 2, and the ends of the connecting posts 4 are fitted with the strip plate 1 with a clearance fit, allowing the U-shaped frames 3 to slide freely at both ends of the strip plate 1, thus adjusting the position of the U-shaped frames 3 on the strip plate 1.

[0026] In order to stabilize the adjusted U-shaped frame 3, such as Figure 3 As shown, a cylindrical block 18 is installed in the middle of the inner side of the U-shaped frame 3, and a receiving groove 19 is provided in the middle of the side of the U-shaped frame 3 away from the strip plate 1. A locking bolt 20 is installed in the receiving groove 19. The end of the locking bolt 20 passes through the cylindrical block 18 and abuts against the strip plate 1. The locking bolt 20 and the end of the cylindrical block 18 are threadedly connected. After the U-shaped frame 3 is adjusted, the locking bolt 20 can be turned so that the end of the locking bolt 20 abuts against the strip plate 1, thereby securing the U-shaped frame 3. In actual use, in order to make the U-shaped frame 3 more stable on the strip plate 1, an elastic rubber block can be installed on the end of the locking bolt 20. The elastic force of the elastic rubber block can be used to apply a reverse elastic force to the U-shaped frame 3 and the strip plate 1, thereby improving the stability of the U-shaped frame 3 on the strip plate 1.

[0027] Furthermore, such as Figure 1 As shown, each U-shaped frame 3 has a mounting plate 7 installed at both ends, and each mounting plate 7 has a strip-shaped mounting hole 8 for fixing the U-shaped frame 3 to a base surface such as a wall. When in use, bolts can be taken and passed through the mounting holes 8 to tighten the U-shaped frame 3 with bolts.

[0028] like Figure 2 and Figure 3As shown, on the side of the U-shaped frame 3 away from the strip plate 1, U-shaped plates 9 with upward openings are installed at both ends. At least two spaced-apart first arc-shaped spring pieces 10 are provided on both sides of the interior of the U-shaped plate 9, with the inner side of the first arc-shaped spring piece 10 facing the inner wall of the U-shaped plate 9. Second arc-shaped spring pieces 11 are connected to both sides of the first arc-shaped spring pieces 10. The concave direction of the second arc-shaped spring piece 11 is opposite to the concave direction of the first arc-shaped spring piece 10 and they are tangent to each other. The other end of the second arc-shaped spring piece 11 is fixed to the inner wall of the U-shaped plate 9. On the side of the U-shaped frame 3 away from the strip plate 1, a fixing plate 12 is provided. On the upper and lower ends of the fixing plate 12 near the strip plate 1, connecting plates 13 with "L"-shaped ends are provided. The ends of the connecting plates 13 are connected to... The fixing plate 12 is fixed, and several spaced limiting strips 14 are installed on the side of the connecting plate 13. The gap between the first arc-shaped spring piece 10 and the two adjacent limiting strips 14 corresponds. In use, the fixing plate 12 is taken out and the connecting plate 13 is pressed down into the U-shaped plate 9 from above. As the connecting plate 13 goes deeper into the U-shaped plate 9, the limiting strips 14 on the connecting plate 13 will contact the arc-shaped spring piece and cause the arc-shaped spring piece to deform. This allows the limiting strip 14 to be embedded between the two adjacent first arc-shaped spring pieces 10, so that the connecting plate 13 is stable in the U-shaped plate 9. When it is necessary to remove the fixing plate 12, it is only necessary to lift the fixing plate 12 upward to remove it, which improves the ease of disassembly and assembly of the fixing plate 12.

[0029] Furthermore, in order to improve the support strength of the U-shaped frame 3, several spaced reinforcing plates are installed at both ends of the inner side of the U-shaped frame 3, and the sides of the reinforcing plates are fixed to the inner wall of the U-shaped frame 3.

[0030] Specifically, in use, a plurality of spaced screw holes 15 are provided on the fixing plate 12. Several first sleeves 16 are provided on the side of the fixing plate 12 away from the strip plate 1. A second sleeve 17 is installed at the end of the first sleeve 16 near the fixing plate 12. The outer diameter of the second sleeve 17 is smaller than the outer diameter of the first sleeve 16, and the inner diameter of the second sleeve 17 is the same as the inner diameter of the first sleeve 16. The second sleeve 17 is threaded into the screw holes 15. This utility model also includes an electronic device, including a housing 22, which is a perforated housing with grooved surfaces. A sensor module and a controller are disposed inside the housing 22. The controller is connected to the sensor module via wires. The sensor module includes a temperature sensor and a humidity sensor. A through hole is provided on one side of the housing 22, the diameter of which is the same as that of the second sleeve. The inner diameter of 17 is consistent, and the through hole is provided with a threaded groove. The thread direction of the threaded groove is consistent with that of the screw hole 15. When installing the electronic device, the fixing plate 12 can be removed from the U-shaped plate 9 first, and then the fixing plate 12 can be placed on the housing 22. It should be noted that the number of screw holes 15 is greater than the number of through holes on the housing 22. The appropriate screw hole 15 installation sleeve can be selected according to the size of the housing 22 itself. Then the fixing plate 12 is placed on the housing 22 and the bolt is passed through the sleeve and rotated to fix the fixing plate 12 to the housing 22. After that, the housing 22 can be lifted, and the connecting plate 13 is placed in the U-shaped plate 9 to fix the housing 22. When it is necessary to maintain the sensor module inside the housing 22, the housing 22 can be lifted up by hand to remove it for maintenance.

[0031] Furthermore, multiple spaced and insulated heat dissipation plates 21 are installed on the side of the fixed plate 12 away from the strip plate 1. The heat dissipation plates 21 are perpendicular to the fixed plate 12, and the fixed plate 12 is a heat-conducting plate to conduct the heat generated by the sensor module and controller, which is then dissipated after contact with the outside air, thereby improving the heat dissipation effect of the sensor module and controller.

[0032] 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 the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
