Description

Technical Field

[0001] This utility model relates to the field of signal testing equipment technology, specifically a portable urban rail transit wireless antenna signal strength testing device. Background Technology

[0002] With the rapid development of cities, urban rail transit has become a key infrastructure for alleviating surface traffic congestion and improving the efficiency of citizens' travel. Urban rail transit systems rely on highly reliable and efficient wireless communication networks to ensure the safe operation of trains, the accurate transmission of passenger information, and the real-time monitoring of various equipment;

[0003] The installation structure of existing detection devices is usually relatively fixed, and they are installed using bolts, welding and other methods. Due to the lack of a convenient fine-tuning mechanism, it is difficult to adjust if a slight deviation in position is found after installation. Utility Model Content

[0004] The purpose of this invention is to provide a portable wireless antenna signal strength testing device for urban rail transit, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a portable urban rail transit wireless antenna signal strength testing device, comprising: a testing device body, and further comprising:

[0006] Fixed position;

[0007] A transmission assembly is placed inside a fixed compartment. The transmission assembly includes a transmission frame slidably connected to the fixed compartment, a third transmission column rotatably connected inside the transmission frame, a transmission gear fixedly connected to the third transmission column, a gear rod meshing with the transmission gear, a second transmission column fixedly connected to the gear rod, a first transmission column slidably connected to the second transmission column, a motor fixedly connected to the first transmission column, and a lever fixedly connected to the third transmission column.

[0008] The fastening assembly includes a mechanical telescopic rod fixedly connected to a first transmission column. A rotating block is fixedly connected to the side of the mechanical telescopic rod away from the first transmission column. A transmission rod is slidably connected to the rotating block. A first connecting rod is fixedly connected to the transmission rod. A transmission block is slidably connected to the first connecting rod. A downward pressure rod is fixedly connected to the transmission block. A threaded groove is formed on the rotating block.

[0009] Furthermore, the side of the motor furthest from the first transmission column is fixedly connected to the fixed chamber.

[0010] By adopting the above technical solution, the motor can be fixed in place, ensuring that it will not rotate on its own during use.

[0011] Furthermore, the first transmission column is provided with an inclined groove, and the second transmission column is slidably connected to the inclined groove on the fixed chamber.

[0012] The above technical solution is adopted: by setting an inclined groove on the first transmission column, it is easy for the second transmission column to slide in it during use.

[0013] Furthermore, the fixed chamber has an opening, the transmission block is slidably connected to the opening in the fixed chamber, the transmission block has an inclined groove, and the first connecting rod is slidably connected to the inclined groove in the transmission block.

[0014] The above technical solution is adopted: by opening a hole in the fixed chamber, the sliding of the transmission block is limited while the transmission block slides in the chamber during use.

[0015] Furthermore, the rotating block is threadedly connected to the fixed chamber.

[0016] The above technical solution involves setting a rotating block and a fixed chamber to be threaded together, allowing displacement to occur when the rotating block rotates during use.

[0017] Furthermore, the bottom of the detection device body is fixedly connected to the transmission frame, and a universal joint is fixedly connected between the rotating block and the transmission rod.

[0018] The above technical solution, by incorporating a universal joint, makes the connection between the rotating block and the transmission block more flexible during use.

[0019] Furthermore, a second connecting rod is fixedly connected to the pressing rod, and there are two pressing rods. The two pressing rods are respectively fixedly connected to the two ends of the second connecting rod. A sliding rod is fixedly connected to the transmission rod, and the sliding rod is slidably connected to the fixed chamber.

[0020] The above technical solution involves setting two downward pressure rods, which can press down on the detection device body to make it more stable.

[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0022] In this invention, the second transmission column is slidable by starting the motor. Under the limiting action of the inclined groove of the first transmission column, the transmission frame is slidable by the gear rod. This allows for convenient adjustment of the position of the detection device body. Compared with existing methods of fixing and installing with bolts or welding, the operator can manually move the mechanical telescopic rod to rotate the third transmission column, which in turn rotates the transmission gear, thereby controlling the movement of the two gear rods and changing the relative position of the second and first transmission columns. Since the two inclined grooves on the first transmission column have different angles, the sliding range of the transmission frame can change when the motor is restarted. The range of position change of the detection device body can be flexibly adjusted according to actual needs, solving the problem of difficulty in adjusting the position of the detection device in the prior art.

[0032] 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.

[0033] Example:

[0034] like Figures 1-5 As shown, this utility model provides a technical solution: a portable urban rail transit wireless antenna signal strength testing device, comprising: a testing device body 11, and further comprising:

[0035] Fixed Warehouse 1;

[0036] The transmission assembly 2 is placed inside the fixed chamber 1. The transmission assembly 2 includes a transmission frame 21 slidably connected to the fixed chamber 1. A third transmission column 27 is rotatably connected inside the transmission frame 21. A transmission gear 26 is fixedly connected to the third transmission column 27. A gear rod 24 meshes with the transmission gear 26. A second transmission column 25 is fixedly connected to the gear rod 24. A first transmission column 23 is slidably connected to the second transmission column 25. A motor 22 is fixedly connected to the first transmission column 23. A lever 28 is fixedly connected to the third transmission column 27.

[0037] Fastening assembly 3 includes a mechanical telescopic rod 38 fixedly connected to the first transmission column 23. A rotating block 37 is fixedly connected to the side of the mechanical telescopic rod 38 away from the first transmission column 23. A transmission rod 31 is slidably connected to the rotating block 37. A first connecting rod 35 is fixedly connected to the transmission rod 31. A transmission block 33 is slidably connected to the first connecting rod 35. A pressing rod 34 is fixedly connected to the transmission block 33. A threaded groove is provided on the rotating block 37.

[0038] In this invention, the second transmission column 25 is slidable by starting the motor 22. Under the limiting action of the inclined groove of the first transmission column 23, the transmission frame 21 is slidable by the gear rod 24. This allows for convenient adjustment of the position of the detection device body 11. Compared with existing methods of fixing and installing with bolts, welding, etc., the operator can manually move the mechanical telescopic rod 38 to rotate the third transmission column 27, which in turn rotates the transmission gear 26. This controls the movement of the two gear rods 24, changing the relative position of the second transmission column 25 and the first transmission column 23. Since the two inclined grooves on the first transmission column 23 have different angles, the sliding range of the transmission frame 21 can change when the motor 22 is restarted. The range of position change of the detection device body 11 can be flexibly adjusted according to actual needs, solving the problem of difficulty in adjusting the position of the detection device in the prior art.

[0039] Furthermore, as shown in the figure, the side of the motor 22 furthest from the first transmission column 23 is fixedly connected to the fixed chamber 1. By fixing the motor 22, it can be ensured that the motor 22 will not rotate during the operation of the testing device. This ensures that the power output of the motor 22 can be stably and accurately transmitted to the first transmission column 23, avoiding power transmission deviation caused by the rotation of the motor 22, thereby making the operation of the entire transmission assembly 2 more reliable and providing stable power support for the position adjustment of the testing device body 11.

[0040] like Figure 2 , Figure 3 As shown, the first transmission column 23 has an inclined groove, and the second transmission column 25 is slidably connected in the inclined groove on the fixed chamber 1. When the motor 22 drives the first transmission column 23 to rotate, the inclined groove can provide a specific motion trajectory for the second transmission column 25, so that the second transmission column 25 can slide smoothly in it, converting the rotational motion of the first transmission column 23 into the linear sliding motion of the second transmission column 25, thereby driving the gear rod 24 and the transmission frame 21 to move, and realizing the position adjustment of the detection device body 11.

[0041] The fixed chamber 1 has an opening, and the transmission block 33 is slidably connected to the opening in the fixed chamber 1. The transmission block 33 has an inclined groove, and the first connecting rod 35 is slidably connected to the inclined groove in the transmission block 33. By having an opening in the fixed chamber 1, during the sliding process of the transmission block 33, the opening not only provides sliding space for the transmission block 33 to slide within it, but also effectively limits the sliding direction and range of the transmission block 33, ensuring that the transmission block 33 moves along a predetermined trajectory. At the same time, the cooperation between the inclined groove on the transmission block 33 and the first connecting rod 35 can transmit the movement of the transmission rod 31 to the transmission block 33, thereby driving the downward pressing rod 34 to move.

[0042] like Figures 4 to 5 As shown, the rotating block 37 is threadedly connected to the fixed chamber 1. By setting the rotating block 37 to be threadedly connected to the fixed chamber 1, when the first transmission column 23 rotates and drives the mechanical telescopic rod 38 to rotate, the rotating block 37 will also rotate. While rotating, the rotating block 37 will be displaced along the thread direction.

[0043] The bottom of the detection device body 11 is fixedly connected to the transmission frame 21. A universal joint 39 is fixedly connected between the rotating block 37 and the transmission rod 31. By providing the universal joint 39, when the rotating block 37 rotates and moves, the universal joint 39 can flexibly adjust the angle and direction of the transmission rod 31, making the connection between the rotating block 37 and the transmission block 33 more flexible. This can avoid jamming or interference caused by the relative position change between the rotating block 37 and the transmission rod 31, and ensure the smoothness of transmission.

[0044] like Figures 1 to 3 As shown, a second connecting rod 36 is fixedly connected to the pressing rod 34. Two pressing rods 34 are provided, each fixedly connected to one end of the second connecting rod 36. A sliding rod 32 is fixedly connected to the transmission rod 31, and the sliding rod 32 is slidably connected to the fixed chamber 1. By providing two pressing rods 34, when the transmission block 33 drives the pressing rods 34 to move, the two pressing rods 34 can press down on the detection device body 11 from different positions, allowing it to be more stably fixed to the fixed chamber 1 after position adjustment. Simultaneously, the sliding of the sliding rod 32 on the fixed chamber 1 provides guidance and limitation for the movement of the transmission rod 31, ensuring the accuracy and stability of the pressing rod 34's movement.

[0045] Working principle: such as Figures 1 to 5 As shown, when it is necessary to adjust the position of the detection device body 11, the motor 22 is started, which causes the motor 22 to drive the second transmission column 25 to slide. Under the limiting action of the inclined groove on the first transmission column 23, the gear rod 24 will drive the transmission frame 21 to slide on the fixed chamber 1, thereby adjusting the position of the detection device body 11.

[0046] During this process, the staff can manually move the mechanical telescopic rod 38, causing the mechanical telescopic rod 38 to drive the third transmission column 27 to rotate, causing the transmission gear 26 to rotate. In turn, the transmission gear 26 drives one of the two gear rods 24 to move closer to the first transmission column 23 and cause the second transmission column 25 to slide into the first transmission column 23, while the second transmission column 25 on the other gear rod 24 moves away from the first transmission column 23. When the motor 22 is started again, the sliding range of the transmission frame 21 will change because the two inclined slots on the first transmission column 23 have different angles.

[0047] When the first transmission column 23 rotates, it will cause the first transmission column 23 to rotate, causing the mechanical telescopic rod 38 to rotate, which will drive the rotating block 37 threadedly connected to the fixed chamber 1 to move, causing the transmission rod 31 to move, causing the first connecting rod 35 to slide in the transmission block 33, driving the transmission block 33 to press down, causing the pressing rod 34 to press against the transmission frame 21.

[0048] Since the mechanical telescopic rod 38 is square, it will not be unable to transmit the rotation on the first transmission column 23 to the rotating block 37.

[0049] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present utility model. The implementation schemes in the above embodiments can also be further combined or replaced. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
