Technical Field
[0001] The utility model relates to the technical field of wireless communication equipment, in particular to a multi-serial port expandable wireless communication terminal. Background Art
[0002] Wireless communication terminals refer to devices that can transmit data and information through wireless signals. Such devices use wireless technologies such as electromagnetic waves, infrared rays, and radio frequencies to achieve communication, and can transmit data such as sound, text, pictures, and videos without physical connection. Common wireless communication terminals include mobile phones, tablets, wireless routers, satellite communication equipment, and Internet of Things devices. Wireless communication terminals are widely used and play an important role in various fields. In the field of personal consumption, smartphones and tablets provide communication, entertainment, payment and other functions.
[0003] In the prior art, in recent years, wireless communication terminals have played a vital role in emergency communications, disaster relief, large-scale activities and field operations. In the face of natural disasters such as earthquakes and floods, traditional wired communication infrastructure will be severely damaged, resulting in communication interruptions. At this time, the portability and rapid deployment capabilities of wireless communication terminals are particularly important. When natural disasters occur, wireless communication terminals can only be temporarily fixed due to environmental restrictions. During field operations, the equipment is difficult to fix with bolts, which reduces the scope of application of the equipment. Utility Model Content
[0004] The utility model aims to solve the shortcomings in the prior art and proposes a multi-serial port expandable wireless communication terminal.
[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a multi-serial port expandable wireless communication terminal, including a terminal device, serial port expansion groups are fixed on both sides of the terminal device, fixing plates are fixed on both sides of the terminal device, a bottom circular hole is opened at the bottom of the terminal device, a trapezoidal groove is opened on the inner wall of the bottom circular hole, a trapezoidal member is slidably connected to the inner wall of the trapezoidal groove, a driven cylinder is fixed at one end of the trapezoidal member, a ground cone is fixed in a circular array at one end of the driven cylinder, an active column is slidably connected to the inner wall of the driven cylinder, a cam ring groove is opened on the circumferential surface of the active column, a track cutting pin is fixed on the inner wall of the driven cylinder, and the track cutting pin The surface is slidably connected with the inner wall of the cam ring groove, and a motor is provided at one end of the active column. In the prior art, in recent years, wireless communication terminals have played a vital role in emergency communications, disaster relief, large-scale activities and field operations. In the face of natural disasters such as earthquakes and floods, traditional wired communication infrastructure will be severely damaged, resulting in communication interruption. At this time, the portability and rapid deployment capabilities of wireless communication terminals are particularly important. When natural disasters occur, wireless communication terminals can only be temporarily fixed due to environmental restrictions. In field operations, it is difficult to fix the equipment with bolts, which reduces the scope of application of the equipment. The utility model solves this kind of problem by installing a ground cone at the bottom of the terminal device, so that when the staff needs to temporarily fix the terminal device when working in the field, because the field ground often does not have the conditions for fixing the device with a fixing plate, the staff presses the terminal device to the ground and starts the motor to rotate the active column at the same time, and the track cutting pin is pushed in the cam ring groove. The movement process is precisely controlled to ensure that the track cutting pin moves to the lowest point of the cam ring groove, so that the driven cylinder moves downward, and the trapezoidal member slides along the inner wall of the trapezoidal groove to maintain the stability of the movement. The ground cone is exposed from the bottom surface of the terminal device and inserted into the ground for temporary fixation. The design of the ground cone takes into consideration Taking into account the diversity of field ground, whether it is sand, grass or gravel, the ground cone can be effectively inserted into the ground, so that workers can temporarily fix equipment on the ground in the field and conveniently establish a temporary communication center, which greatly simplifies the process of workers establishing temporary communication centers in field environments, while improving work efficiency and the safety of on-site operations. The fixing mechanism not only improves the adaptability and reliability of the equipment, but also provides great convenience for workers when working in the field, allowing them to quickly respond to various emergencies and effectively complete communication tasks, thereby improving user experience and increasing work efficiency.
[0006] Preferably, a threaded hole is provided at the bottom of the terminal device, a threaded column is threadedly connected to the inner wall of the threaded hole, and a round table support is fixed to one end of the threaded column. In the prior art, when a fixing plate is used to fasten the device in place, since the device is designed to be in close contact with the wall, it will become particularly sensitive to vibration and humidity conditions because it is too close to the wall. This close installation method means that any vibration transmitted to the wall will directly act on the device, increasing the risk of damage to the device. The use of the fixing plate limits the applicability and flexibility of the device in different environments. Since the fixing plate usually needs to be used in conjunction with a relatively solid and flat surface, it can be used in a variety of natural environments, such as outdoors, on sand or other unconventional surfaces. It is difficult to achieve stable fixation and temporary placement. These environments often require more flexible and adaptable fixing solutions to ensure the safety and operating effect of the equipment. When facing complex and changeable field conditions, a single fixing method cannot meet the necessary fixing requirements, limiting the scope of use and practicality of the equipment. To address such problems, the utility model solves them by installing threaded columns. When the staff needs to fix or install the equipment, the threaded columns are screwed into the threaded holes according to the actual situation, so that the frustum supports prevent the equipment from contacting the wall when fixed. The frustum supports are used to ensure that the equipment maintains an appropriate gap when fixed, thereby avoiding direct contact between the equipment and the wall and reducing the potential impact of vibration and moisture on the equipment. In addition, when the equipment needs to be placed temporarily, the round table support plays a supporting role to prevent the bottom of the equipment from contacting the ground and protect the equipment from scratches or other surface damage. In special environments, such as soft soil such as sand, if the staff needs to temporarily fix the equipment, they can also use the round table support to achieve this. Press the equipment hard to insert the round table support directly into the sand, and use it as an anchor point to stabilize the equipment, ensuring the stability and safety of the equipment during use. The design of the round table support allows it to be effectively inserted into soft or irregular surfaces, providing the necessary support and stability for the equipment, meeting the needs of temporary fixation, and achieving the effect of increasing the scope of application of the equipment.
[0007] Preferably, a circular groove is formed at the bottom of the truncated cone support, and a rubber pad is detachably connected to the inner wall of the circular groove, and a cross anti-skid pattern is formed on the bottom surface of the rubber pad. In the prior art, when the truncated cone support is used to support equipment, its small contact area often leads to displacement when subjected to external forces. This is because the contact surface is small. Once the truncated cone support encounters external forces, it cannot effectively resist these forces, causing it to move on the supporting surface. This displacement will affect the stability of the equipment, increase the risk of the equipment shaking or becoming unstable during use, and reduce the stability of the equipment. To solve this problem, the utility model adopts the method of installing rubber pads to achieve that when the equipment needs to be temporarily placed, the rubber pad uses the friction properties of the rubber material itself to increase the friction with the surface when contacting the desktop, thereby improving the stability of the equipment. The cross anti-slip pattern further enhances the grip and effectively prevents accidental slipping of the equipment during use, ensuring that the equipment remains fixed even on inclined or smooth surfaces, reducing the risk of sliding or displacement. Taking into account the differences in support requirements in different usage environments, when workers work on soft ground such as sand, they need to insert the round table support directly into the ground to stabilize the equipment. In this case, the detachable design allows workers to remove the rubber pad from the round groove in advance to avoid the anti-slip effect being reduced due to sand adhesion when used on sandy ground. Removing the rubber pad not only helps maintain its anti-slip performance, but also makes it easier to insert the round table support directly into the sand, providing a flexible fixing method that can adapt to changing terrain conditions, ensuring the stability and reliability of the equipment when temporarily fixed, and achieving the effect of increasing the scope of application of the equipment.
[0008] Preferably, the ground cone is configured as a non-pointed cone. In the prior art, the ground cone is a tool for fixing equipment. Since the cone head is very sharp, workers are very likely to be scratched if they are not careful during operation. Although the sharp cone head can easily penetrate the ground and achieve quick insertion, this design also makes it more likely to encounter problems during use. For example, when encountering a harder surface or when too much force is applied, the pointed head may break or bend, which not only affects the use effect of the ground cone, but may also cause failure in fixing the equipment, thereby affecting the work progress and the safety and stability of the equipment. To address such problems, the utility model solves them by configuring the ground cone to be a non-pointed cone, so that when the ground cone is used to fix equipment, the relatively smooth and blunt cone end reduces the risk of scratches on workers during operation, and the non-pointed cone design increases The area of ground contact, although the insertion speed may not be as fast as that of the sharp head, it can form an obvious concave indentation on the ground by applying greater pressure. This indentation creates convenient conditions for the further penetration of the ground cone, making the subsequent insertion action smoother and improving the overall insertion efficiency. Due to the pressure of the non-sharp head on the ground, it can pre-separate the ground material to a certain extent, paving the way for the subsequent insertion part. This not only improves the ability of the ground cone to be inserted into the ground, but also helps to reduce the wear of the ground cone caused by repeated use and extend the service life of the ground cone. When the ground is concave, it can also help to fix the equipment more firmly to the ground, because the gravity of the equipment will combine with the indentation formed by the ground cone, further improving the stability of the fixation, thereby achieving the effect of improving the stability of the equipment.
[0009] Preferably, the trapezoidal groove is set to a trapezoidal shape, and the trapezoidal member is set to a trapezoidal shape. The combination of the two can limit the left and right sliding of the components while stabilizing the movement of the mechanism, so that the power output direction of the equipment is more concentrated, and the energy utilization rate of the equipment is improved.
[0010] Preferably, the truncated cone support is configured as a truncated cone cube, which increases the contact area between the truncated cone support and the bottom of the device without increasing the material consumption, thereby improving the supporting effect of the component and improving the stability of the device.
[0011] Preferably, the length of the trapezoidal groove is greater than the length of the trapezoidal member, which limits the movement distance of the trapezoidal member, avoids excessive power output, and increases the service life of the equipment.

[0025] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the present invention is further described below in conjunction with specific embodiments and drawings, but the following embodiments are only preferred embodiments of the present invention, not all. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the present invention.
[0026] The specific embodiments of the present utility model are described below in conjunction with the accompanying drawings. Specific embodiment:
[0028] Reference Figure 1-6A multi-serial port expandable wireless communication terminal comprises a terminal device 1, a serial port expansion group 101 is fixed on both sides of the terminal device 1, a fixing plate 102 is fixed on both sides of the terminal device 1, a bottom circular hole 2 is opened at the bottom of the terminal device 1, a trapezoidal groove 201 is opened on the inner wall of the bottom circular hole 2, a trapezoidal member 202 is slidably connected to the inner wall of the trapezoidal groove 201, a driven cylinder 203 is fixed at one end of the trapezoidal member 202, a ground cone 204 is fixed in a circumferential array at one end of the driven cylinder 203, an active column 206 is slidably connected to the inner wall of the driven cylinder 203, a cam ring groove 207 is opened on the circumference of the active column 206, a track cutting pin 205 is fixed on the inner wall of the driven cylinder 203, and the surface of the track cutting pin 205 The active column 206 is slidably connected to the inner wall of the cam ring groove 207, and a motor 208 is provided at one end of the active column 206. In recent years, wireless communication terminals have played a vital role in emergency communications, disaster relief, large-scale activities and field operations. In the face of natural disasters such as earthquakes and floods, traditional wired communication infrastructure will be severely damaged, resulting in communication interruption. At this time, the portability and rapid deployment capabilities of wireless communication terminals are particularly important. When natural disasters occur, wireless communication terminals can only be temporarily fixed due to environmental restrictions. In field operations, it is difficult to fix the equipment with bolts, which reduces the scope of application of the equipment. A ground cone is installed at the bottom of the terminal device 1. The method 204 solves the problem. When the staff needs to temporarily fix the terminal device 1 when working in the field, because the field ground often does not have the conditions for fixing the device with the fixing plate 102, the staff presses the terminal device 1 to the ground and starts the motor 208 to rotate the active column 206. The track cutting pin 205 is pushed in the cam ring groove 207. The movement process is precisely controlled to ensure that the track cutting pin 205 moves to the lowest point of the cam ring groove 207, so that the driven cylinder 203 moves downward. At the same time, the trapezoidal member 202 slides along the inner wall of the trapezoidal groove 201 to maintain the stability of the movement. The ground cone 204 exposes the bottom surface of the terminal device 1 and is inserted into the ground for temporary fixation. The design of cone 204 takes into account the diversity of the ground in the field. Whether it is sand, grass or gravel, cone 204 can be effectively inserted into the ground, so that workers can also temporarily fix the equipment on the ground in the field, conveniently establish a temporary communication center, greatly simplify the process of workers establishing temporary communication centers in the field environment, and at the same time improve work efficiency and safety of on-site operations. The fixing mechanism not only improves the adaptability and reliability of the equipment, but also provides great convenience for workers when working in the field, allowing them to quickly respond to various emergencies and effectively complete communication tasks, thereby improving user experience and increasing work efficiency. The trapezoidal groove 201 is set to a trapezoidal shape, and the trapezoidal member 202 is set to a trapezoidal shape. The combination of the two limits the left and right sliding of the components while stabilizing the movement of the mechanism, making the power output direction of the equipment more concentrated and improving the energy utilization rate of the equipment. The length of the trapezoidal groove 201 is greater than the length of the trapezoidal member 202, which limits the movement distance of the trapezoidal member 202, avoids power output interference, and increases the service life of the equipment.
[0029] A threaded hole 3 is provided at the bottom of the terminal device 1, and a threaded column 301 is threadedly connected to the inner wall of the threaded hole 3, and a round table support 302 is fixed to one end of the threaded column 301. When the device is fastened in place using the fixing plate 102, since the device is designed to be in close contact with the wall, it will become particularly sensitive to vibration and humidity conditions because it is too close to the wall. This close installation method means that any vibration transmitted to the wall will directly act on the device, increasing the risk of damage to the device. The use of the fixing plate 102 limits the applicability and flexibility of the device in different environments. Since the fixing plate 102 usually needs to be used in conjunction with a relatively solid and flat surface, it is not suitable for use in a variety of natural environments, such as outdoors, on sand or other unconventional surfaces. It may be difficult to achieve stable fixation and temporary placement. These environments often require more flexible and adaptable fixing solutions to ensure the safety and operation effect of the equipment. When facing complex and changeable field conditions, a single fixing method cannot meet the necessary fixing requirements, limiting the scope of use and practicality of the equipment. The threaded column 301 is installed to solve the problem. When the staff needs to fix or install the equipment, the threaded column 301 is screwed into the threaded hole 3 according to the actual situation, so that the round cone support 302 prevents the equipment from contacting the wall when fixed. The round cone support 302 is used to ensure that the equipment maintains an appropriate gap when fixed, thereby avoiding direct contact between the equipment and the wall and reducing the potential impact of vibration and moisture on the equipment. In addition, when the equipment needs to be temporarily placed, the truncated cone support 302 plays a supporting role, preventing the bottom of the equipment from contacting the ground, and protecting the equipment from scratches or other surface damage. In special environments, such as soft soil such as sand, if the staff needs to temporarily fix the equipment, they can also use the truncated cone support 302 to achieve this. Press the equipment hard to insert the truncated cone support 302 directly into the sand, and use it as an anchor point to stabilize the equipment, ensuring the stability and safety of the equipment during use. The design of the truncated cone support 302 allows it to be effectively inserted into soft or irregular surfaces, providing the necessary support and stability for the equipment, meeting the needs of temporary fixation, and achieving the effect of increasing the scope of application of the equipment.A circular groove is provided at the bottom of the truncated cone support 302, and a rubber pad 303 is detachably connected to the inner wall of the circular groove. A cross anti-skid pattern is provided on the bottom surface of the rubber pad 303. When the truncated cone support 302 is used to support the device, its small contact area often leads to displacement when subjected to external forces. This is because the contact surface is small. Once the truncated cone support 302 encounters external forces, it cannot effectively resist these forces, causing it to move on the supporting surface. This displacement will affect the stability of the device and increase the risk of the device shaking or becoming unstable during use, resulting in reduced stability of the device. This problem is solved by installing the rubber pad 303. When the device needs to be temporarily placed, the rubber pad 303 uses the friction characteristics of the rubber material itself to increase the friction with the surface when contacting the desktop, thereby improving the stability of the device. The cross anti-skid pattern on the rubber pad 303 further The grip is improved, which effectively prevents the equipment from accidentally slipping during use, ensures that the equipment can remain fixed even on inclined or smooth surfaces, and reduces the risk of sliding or shifting. Considering the differences in support requirements for different use environments, when workers work on soft ground such as sand, they need to insert the truncated support 302 directly into the ground to stabilize the equipment. In this case, the detachable design allows workers to remove the rubber pad 303 from the circular groove in advance to avoid the anti-slip effect being reduced due to sand adhesion when it is used on sandy ground. Removing the rubber pad 303 not only helps to maintain its anti-slip performance, but also makes it easier to insert the truncated support 302 directly into the sand, providing a flexible fixing method that can adapt to changing terrain conditions, ensuring the stability and reliability of the equipment when temporarily fixed, and achieving the effect of increasing the scope of application of the equipment. The truncated support 302 is set as a truncated cone cube. Without increasing the material, the contact area between the truncated support 302 and the bottom of the equipment is increased, the support effect of the component is improved, and the stability of the equipment is improved.
[0030] The ground cone 204 is designed as a non-pointed cone. The ground cone 204 is a tool for fixing equipment. Since the cone head is very sharp, workers are very likely to be scratched if they are not careful during operation. Although the sharp cone head can easily penetrate the ground and achieve rapid insertion, this design also makes it easier to encounter problems during use. For example, when encountering a harder surface or being applied with too much force, the pointed head may break or bend, which not only affects the use effect of the ground cone 204, but may also cause the failure of fixing the equipment, thereby affecting the work progress and the safety and stability of the equipment. The non-pointed cone is used to solve this problem. When the ground cone 204 is used to fix the equipment, its relatively smooth and blunt cone end reduces the risk of scratches on the workers during operation. The non-pointed cone design increases the contact area with the ground. Although the insertion speed is fast, The speed may not be as fast as that of the sharp head, but by applying greater pressure in a concentrated manner, it can form an obvious concave indentation on the ground. This indentation creates convenient conditions for the further penetration of the ground cone 204, making the subsequent insertion action smoother and improving the overall insertion efficiency. Due to the pressure of the non-sharp head on the ground, it can pre-separate the ground material to a certain extent, paving the way for the subsequent insertion part, which not only improves the ability of the ground cone 204 to be inserted into the ground, but also helps to reduce the wear of the ground cone 204 caused by repeated use, and extends the service life of the ground cone 204. When the ground is concave, it can also help to fix the equipment more firmly to the ground, because the gravity of the equipment will combine with the indentation formed by the ground cone 204, further improving the stability of the fixation, thereby achieving the effect of improving the stability of the equipment.
[0031] Working principle of the utility model: when the staff is working in the field, it is necessary to temporarily fix the terminal device 1. Since the ground in the field often does not have the conditions for fixing the device with the fixing plate 102, the staff presses the terminal device 1 to the ground and starts the motor 208 to rotate the active column 206. The track cutting pin 205 is pushed in the cam ring groove 207. The movement process is precisely controlled to ensure that the track cutting pin 205 moves to the lowest point of the cam ring groove 207, so that the driven cylinder 203 moves downward. At the same time, the trapezoidal member 202 slides along the inner wall of the trapezoidal groove 201 to maintain the stability of the movement. The ground cone 204 exposes the bottom surface of the terminal device 1 and is inserted into the ground for temporary fixation. When the staff needs to fix or install the equipment, the threaded column 301 is screwed into the threaded hole 3 according to the actual situation, so that the truncated cone support 302 prevents the equipment from contacting the wall when fixed. The truncated cone support 302 is used to ensure that the equipment maintains an appropriate gap when fixed, thereby avoiding direct contact between the equipment and the wall and reducing the potential impact of vibration and moisture on the equipment. In addition, when the equipment needs to be temporarily placed, the truncated cone support 302 plays a supporting role to prevent the bottom of the equipment from contacting the ground, protecting the equipment from scratches or other surface damage. In special environments, such as soft soil such as sand, if the staff needs to temporarily fix the equipment, they can also use the truncated cone support 302 to achieve this. Press the equipment hard to insert the truncated cone support 302 directly into the sand, and use it as an anchor point to stabilize the equipment.
