Description

Technical Field

[0001] This utility model relates to the field of signal transmitter box technology, specifically a quick-release modular intelligent signal transmitter box. Background Technology

[0002] Signal transmitters are core devices in fields such as electronic testing, communications, and medical monitoring. Their core function is to generate electrical signals with specific frequencies, waveforms, and modulation methods through built-in circuitry. For example, medical telemetry transmitters use spatial diversity dual antennas and FSK modulation technology to achieve cross-floor signal coverage; radio frequency signal generators can simulate 5G band signals to support the research and testing of communication equipment; and wireless access points (APs) extend WiFi coverage through panel-mounted or ceiling-mounted designs. Their technological evolution encompasses modules such as low-frequency oscillation, power combining, and digital modulation, and they are widely used in electromagnetic compatibility research, quantum communication experiments, and industrial automation calibration.

[0003] Signal transmitter boxes are used for testing signals or transmitting signals. For example, a remote signal transmitter box for vehicle detection, as disclosed in patent publication number CN214954607U, includes: a housing, a touch screen, and a control circuit board. The housing has a power interface and a signal interface. The touch screen is fixedly mounted on the housing, and the user inputs commands through the touch screen. The control circuit board includes an encoder and a microcontroller. The encoder is electrically connected to the microcontroller and the touch screen. The microcontroller includes a main control chip. It also includes an isolated power supply circuit module, an input power protection circuit module, a CAN bus interface circuit module, and a LIN bus interface circuit module.

[0004] However, when using the above-mentioned devices and other existing signal transmitters, the signal transmitters are placed directly on the support surface. When long-term fixation is required, they are connected by screws or other means, which makes it inconvenient to disassemble and assemble the signal transmitters. Utility Model Content

[0005] The purpose of this invention is to provide a quick-release modular intelligent signal transmitter box to solve the problems mentioned in the background art.

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

[0007] The first aspect designs a quick-release modular intelligent signal transmitter box, including a box body. The bottom of the box body is provided with two retaining plates, and the retaining plates have a "convex" structure that is wider at the bottom and narrower at the top. A retaining plate is slidably provided on the outer side of the retaining plates. The retaining plate is provided with a connecting component for fixing, and limit holes are opened at both ends of the retaining plate. A groove is opened on the front side of the lower surface of the box body, and an elastic plate is fixed in the groove. A limit pin is provided on the elastic plate. A sliding hole is opened on the retaining plate, and the limit pin is slidably inserted into the sliding hole, and the sliding hole is aligned with one of the limit holes.

[0008] With the above structure, during use, the slot plate is fixed to the support surface by the connecting component, then the card plate is aligned with the slot plate and inserted from one side. When inserting the card plate, the elastic plate is pressed upward to bend it upward and drive the limiting pin to fully retract into the sliding hole. After the card plate is fully inserted into the slot plate, the elastic plate is released, and the elastic plate drives the limiting pin to move downward and insert into one of the limiting holes, thereby fixing the box and preventing it from slipping out.

[0009] Preferably, the card slot plate has several screw holes for screw fixing, and a magnetic sheet is fixed on the lower surface of the card slot plate for magnetic fixation.

[0010] With the above structure, the card slot plate needs to be fixed to the support surface first. It can be fixed by screws through the screw holes. If the support surface is made of iron, it can also be directly attached to the support surface by magnetic sheets. Multiple fixing methods make it convenient to fix.

[0011] Preferably, the upper surface of the card slot plate is provided with a plurality of equally spaced embedding slots, and a shock-absorbing pad is embedded in the embedding slot. The upper surface of the shock-absorbing pad is chamfered, and the upper surface of the shock-absorbing pad abuts against the lower surface of the box.

[0012] With the above structure, the box body and the shock-absorbing pad abut against each other, which can make the connection between the two tighter, prevent the box body from shaking, and also reduce the collision and friction noise between the box body and the card slot plate in a vibration environment.

[0013] Preferably, the elastic plate has a first long slot, and the limiting pin has slots on both sides. The limiting pin is slidably disposed in the first long slot through the slots. The bottom of the box has several second long slots, and the second long slots are in the shape of dovetail grooves. A trapezoidal nut is slidably disposed in the second long slot. The trapezoidal nut has an anti-slip groove on its side and a screw hole on its surface. The card plate has a connecting hole, and the connecting hole is aligned with the trapezoidal nut and fixed by a fastening bolt.

[0014] With the above structure, when the width of the support surface is insufficient and the distance between the two clamping plates needs to be adjusted, the fastening bolts can be loosened, and then the clamping plates can be slid laterally to the appropriate position. At this time, the trapezoidal nut and the limit pin slide synchronously. Then the fastening bolts are tightened. When the fastening bolts are tightened, the anti-slip grooves on them can provide friction between them and the inner wall of the second long groove to prevent slippage. The clamping plates are fixed by friction, so that the box can be fixed on support surfaces of different sizes, which further facilitates disassembly and assembly.

[0015] Preferably, one end of the first long slot is provided with a first flared hole, and the diameter of the first flared hole is larger than the diameter of the limiting pin; one end of the second long slot is provided with a second flared hole, and the diameter of the second flared hole is larger than the maximum diameter of the trapezoidal nut.

[0016] With the above structure, when assembling the device, the limiting pin can be inserted through the first flared hole and the trapezoidal nut through the second flared hole, making installation more convenient. Moreover, the limiting pin or trapezoidal nut can be replaced automatically if damaged, making the operation simple.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] The sliding snap-fit ​​effect is achieved through the card plate and card slot plate. In addition, an elastic plate is set at the bottom of the box. When installing, press the elastic plate and the limit pin will retract. After installation, release the elastic plate. At this time, the elastic plate can drive the limit pin to move down and insert into one of the limit holes, thereby fixing the box and preventing it from slipping. It is easy to assemble and disassemble.

[0019] At the same time, the card slot plate can be fixed by screws through the screw holes. If the support surface is made of iron, it can also be directly attached to the support surface by magnetic sheets. Multiple fixing methods make it convenient to fix. Attached Figure Description

[0025] like Figures 1-3As shown, this utility model provides a technical solution: a quick-release modular intelligent signal transmitter box includes a box body 1. The bottom of the box body 1 is provided with two retaining plates 2, and the retaining plates 2 have a "convex" structure that is wider at the bottom and narrower at the top. A retaining plate 3 is slidably provided on the outer side of the retaining plate 2. The retaining plate 3 is provided with a connecting component for fixing, and both ends of the retaining plate 3 are provided with limiting holes 8. A groove 4 is provided on the front side of the lower surface of the box body 1, and an elastic plate 5 is fixed in the groove 4. A limiting pin 6 is provided on the elastic plate 5. A sliding hole 7 is provided on the retaining plate 2, and the limiting pin 6 is slidably inserted into the sliding hole 7, and the sliding hole 7 is aligned with one of the limiting holes 8.

[0026] It should be noted that during use, the slot plate 3 is fixed to the support surface by connecting the components, and then the card plate 2 is aligned with the slot plate 3 and inserted from one side. When inserting the card plate 2, the elastic plate 5 is pressed upward to bend it upward and drive the limiting pin 6 to fully retract into the sliding hole 7. After the card plate 2 is fully inserted into the slot plate 3, the elastic plate 5 is released. The elastic plate 5 drives the limiting pin 6 to move downward and insert into one of the limiting holes 8, thereby fixing the box body 1 and preventing it from slipping out.

[0027] like Figure 1 and Figure 2 As shown, the card slot plate 3 has several screw holes 10 for screw fixing, and a magnetic sheet 9 is fixed on the lower surface of the card slot plate 3 for magnetic fixation.

[0028] It should be noted that when using it, the card slot plate 3 needs to be fixed to the support surface first. The card slot plate 3 can be fixed by screws through the screw holes 10. If the support surface is made of iron, it can also be directly attached to the support surface by magnetic sheet 9. There are multiple fixing methods to facilitate fixing.

[0029] like Figure 2 As shown, the upper surface of the card slot plate 3 is provided with several equally spaced embedding slots 11, and a shock-absorbing pad 12 is embedded in the embedding slot 11. The upper surface of the shock-absorbing pad 12 is provided with a chamfer 13, and the upper surface of the shock-absorbing pad 12 abuts against the lower surface of the box body 1.

[0030] It should be noted that the box body 1 and the shock-absorbing pad 12 abut against each other, which can make the connection between the two tighter, prevent the box body 1 from shaking, and also reduce the collision and friction noise between the box body 1 and the card slot plate 3 in a vibration environment.

[0031] like Figure 3As shown, the elastic plate 5 has a first long slot 14, and the limiting pin 6 has slots 15 on both sides. The limiting pin 6 is slidably disposed in the first long slot 14 through the slots 15. The bottom of the box body 1 has several second long slots 16, and the second long slots 16 are dovetail-shaped. A trapezoidal nut 17 is slidably disposed in the second long slot 16. The side of the trapezoidal nut 17 is provided with an anti-slip groove, and the trapezoidal nut 17 has a screw hole. The card plate 2 has a connecting hole 18, and the connecting hole 18 is aligned with the trapezoidal nut 17 and fixed by a fastening bolt 19.

[0032] It should be noted that when the width of the support surface is insufficient and the distance between the two clamping plates 2 needs to be adjusted, the fastening bolt 19 can be loosened, and then the clamping plate 2 can be slid laterally to the appropriate position. At this time, the trapezoidal nut 17 and the limit pin 6 slide synchronously. Then the fastening bolt 19 can be tightened. When the fastening bolt 19 is tightened, the anti-slip groove on it can provide friction between it and the inner wall of the second long slot 16 to prevent slippage. The clamping plate 2 is fixed by friction, so that the box body 1 can be fixed on support surfaces of different sizes, which further facilitates disassembly and assembly.

[0033] like Figure 3 As shown, a first flared hole 20 is provided at one end of the first long slot 14, and the diameter of the first flared hole 20 is greater than the diameter of the limiting pin 6. A second flared hole 21 is provided at one end of the second long slot 16, and the diameter of the second flared hole 21 is greater than the maximum diameter of the trapezoidal nut 17.

[0034] It should be noted that when assembling the device, the limiting pin 6 can be inserted through the first flared hole 20 and the trapezoidal nut 17 can be inserted through the second flared hole 21, making installation more convenient. Moreover, the limiting pin 6 or the trapezoidal nut 17 can be replaced automatically if damaged, making the operation simple.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended embodiments and their equivalents.
