Technical Field
[0001] This utility model relates to the technical field of antenna receiving test devices, and in particular to a test device for testing the receiving capability of an antenna. Background Technology
[0002] An antenna is a transducer that transforms guided waves propagating on a transmission line into electromagnetic waves propagating in an unbounded medium, or vice versa. During the antenna manufacturing process, reception capability testing is required, which typically involves using an antenna analyzer. An antenna analyzer is an instrument used to measure various characteristic parameters of an antenna.
[0003] During the use of antenna receiving test equipment, traditional antenna analyzers are usually stored in a box. When using them, the antenna analyzer needs to be picked up and put away frequently. During this process, the antenna analyzer is easy to slip from your hand or be bumped. Furthermore, if the antenna analyzer is hit while stored in the box, it will be damaged.
[0004] Therefore, to address the aforementioned issues of inconvenience in facilitating the use and ensuring the safety of antenna analyzers, a testing device for testing antenna receiving capabilities can be designed. During use, the antenna receiving testing device, under the elastic action of the return spring, can push the locking rod into the locking hole. Furthermore, under the action of the shock-absorbing damping ring and the shock-absorbing spring, the antenna analyzer can achieve both convenient use and safety protection. Utility Model Content
[0005] To address the issue that antenna analyzers need to be removed from their housing and placed on the ground during use, and then reinstalled afterward, which can be damaged if the analyzer is not held securely, improvements are urgently needed to ensure convenient use and safety of the antenna analyzer.
[0006] The technical solution of this utility model is as follows: a testing device for testing the receiving capability of an antenna, comprising a shell, a support base, a shock-absorbing base, an antenna analyzer, an L-shaped frame, guide columns, an adjustment groove, a return spring, a locking rod, a guide cylinder, a pressing rod, a locking hole, a shock-absorbing damping ring, and a shock-absorbing spring. The support base is located inside the shell, and the shock-absorbing base is located above the support base. The antenna analyzer is located above the shock-absorbing base. Multiple sets of L-shaped frames are fixedly installed on the top of both sides of the support base, and multiple sets of guide columns are fixedly installed on the bottom of both sides of the shock-absorbing base. An adjustment groove is opened on the side wall of the support base, and a return spring is fixedly installed inside the adjustment groove. A locking rod is fixedly installed at one end of the return spring. A guide cylinder is fixedly installed on the side wall of the shell, and a pressing rod is slidably installed inside the guide cylinder. A locking hole is opened through the side wall of the shell. A shock-absorbing damping ring is slidably installed on the side wall of the guide column, and a shock-absorbing spring is fixedly installed at the upper end of the shock-absorbing damping ring.
[0007] Preferably, during the use of the antenna receiving test device, firstly, pulling one side of the support base upwards will cause the shock absorber and antenna analyzer to rise and move, achieving an open state. When the top of the antenna analyzer is fully exposed, the adjustment slot and locking hole are at the same level. Under the elastic action of the return spring, the locking rod can be pushed into the locking hole, thus locking the support base and antenna analyzer to their current positions. This design ensures the stability and accuracy of the antenna analyzer during testing. In addition, when the housing is subjected to vibration, multiple sets of guide columns at the bottom of the shock absorber slide along multiple sets of L-shaped frames at the top of the support base. During this process, the shock-absorbing damping ring can slide along the guide columns and generate damping. Friction absorbs vibration energy, and the elasticity of the damping spring further reduces the impact of vibration on the device, ensuring the accuracy and reliability of the test. After testing, when storing the antenna analyzer, firstly, the inner side pushes the squeezing rod, causing one end of the squeezing rod to press against the end of the locking rod. When the end of the locking rod disengages from the locking hole, the support is unlocked. Simultaneously, the antenna analyzer's own weight allows it to be stored inside the housing, thus providing safety protection. In summary, this antenna receiving capability testing device, through its unique component structure and working principle, provides both convenient use and safety protection for the antenna analyzer.
[0008] Preferably, two sets of fixing rings are fixedly installed at both the upper and lower ends of the guide column. The upper end of the shock-absorbing spring is fixedly connected to the inner wall of the upper fixing ring. A buffer spring is fixedly installed at the lower end of the guide column. The lower end of the buffer spring is fixedly connected to the upper end of the support base. The guide column is slidably connected to the L-shaped frame.
[0009] Preferably, one end of the locking rod engages with the locking hole, a guide bead is rotatably provided on one end of the locking rod, and a limit ring is fixedly provided on the side wall of the compression rod.
[0010] Preferably, two sets of slide rails are fixedly installed on both sides of the inner wall of the outer casing, and slide rods are fixedly installed inside the slide rails, with sliders installed on the side walls of the slide rods.
[0011] Preferably, the slider and the slide rod are slidably connected, and both sides of the support base are fixedly connected to the inner walls of the two sliders. A lifting rod is fixedly installed on the side wall of a set of sliders.
[0012] Preferably, two sets of mounting blocks are fixedly installed on both sides of the top of the outer casing. The mounting blocks have mounting holes inside. A mounting shaft is rotatably installed between the two sets of mounting blocks. A casing cover is fixedly installed on the side wall of the mounting shaft.
[0013] Preferably, two sets of spiral springs are provided at both ends of the mounting shaft. One end of the spiral spring is fixedly connected to one end of the mounting shaft, and the other end of the spiral spring is fixedly connected to the inner wall of the mounting hole.
[0014] The beneficial effects of this utility model are:
[0015] During the use of the antenna receiving test device, firstly, pulling one side of the support base upwards will cause the shock absorber and antenna analyzer to rise and open. When the top of the antenna analyzer is fully exposed, the adjustment slot and locking hole are at the same level. Under the elastic action of the return spring, the locking rod can be pushed into the locking hole, locking the support base and antenna analyzer in their current positions. This design ensures the stability and accuracy of the antenna analyzer during testing. Furthermore, when the casing is subjected to vibration, multiple guide columns at the bottom of the shock absorber slide along multiple L-shaped brackets at the top of the support base. During this process, the damping ring slides along the guide columns, generating damping friction. This absorbs vibration energy, and the elasticity of the damping spring further reduces the impact of vibration on the device, ensuring the accuracy and reliability of the test. After testing, when storing the antenna analyzer, firstly, the inner side pushes the squeezing rod, causing one end of the squeezing rod to press against the end of the locking rod. When the end of the locking rod disengages from the locking hole, the support is unlocked. Simultaneously, under the weight of the antenna analyzer itself, it can be stored inside the housing, thus achieving a safe protection effect. In summary, this antenna receiving capability testing device, through its unique component structure and working principle, provides convenient use and safe protection for the antenna analyzer.

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0024] Please see Figure 1 and Figure 6This utility model provides an embodiment: a testing device for testing antenna receiving capability, comprising a housing 1, a support base 2, a shock-absorbing base 3, an antenna analyzer 4, an L-shaped frame 5, a guide column 6, an adjustment groove 7, a return spring 8, a locking rod 9, a guide cylinder 10, a pressing rod 11, a locking hole 12, a shock-absorbing damping ring 13, and a shock-absorbing spring 14. The support base 2 is disposed inside the housing 1, the shock-absorbing base 3 is disposed above the support base 2, and the antenna analyzer 4 is disposed above the shock-absorbing base 3. Multiple [unclear - possibly referring to a specific type of device] are fixedly mounted on the top sides of the support base 2. The L-shaped frame 5 and the shock absorber 3 are fixedly provided with multiple sets of guide columns 6 on both sides of the bottom. The side wall of the support base 2 is provided with an adjustment groove 7. The inside of the adjustment groove 7 is fixedly provided with a return spring 8. One end of the return spring 8 is fixedly provided with a locking rod 9. The side wall of the outer shell 1 is fixedly provided with a guide cylinder 10. The inside of the guide cylinder 10 is slidably provided with a pressing rod 11. The side wall of the outer shell 1 is provided with a locking hole 12. The side wall of the guide column 6 is slidably provided with a shock absorber damping ring 13. The upper end of the shock absorber damping ring 13 is fixedly provided with a shock absorber spring 14.
[0025] Please see Figure 3 and Figure 5 Two sets of fixing rings 15 are fixedly installed at both the upper and lower ends of the guide column 6. The upper end of the shock-absorbing spring 14 is fixedly connected to the inner wall of the upper fixing ring 15. A buffer spring 16 is fixedly installed at the lower end of the guide column 6. The lower end of the buffer spring 16 is fixedly connected to the upper end of the support base 2. The guide column 6 is slidably connected to the L-shaped frame 5. Under the elastic action of the shock-absorbing spring 14 and the buffer spring 16, the antenna analyzer 4 can achieve a shock-absorbing and buffering effect. One end of the locking rod 9 is engaged with the locking hole 12. One end of the 9 is rotatably provided with a guide bead 17, and a limit ring 18 is fixedly provided on the side wall of the compression rod 11. Under the elastic action of the return spring 8, the locking rod 9 can be driven to insert into the locking hole 12, so that the current position of the support base 2 and the antenna analyzer 4 is locked. Two sets of slide rails 19 are fixedly provided on both sides of the inner wall of the outer shell 1. A slide rod 20 is fixedly provided inside the slide rail 19. A slider 21 is provided on the side wall of the slide rod 20. The slider 21 can be adjusted and slid along the slide rod 20.
[0026] Please see Figure 2 and Figure 4The slider 21 is slidably connected to the slide rod 20. Both sides of the support base 2 are fixedly connected to the inner walls of the sliders 21 on both sides. A lifting rod 22 is fixedly installed on the side wall of a set of sliders 21. Pulling the lifting rod 22 upward will drive a set of sliders 21 to move upward along the slide rod 20. Two sets of mounting blocks 23 are fixedly installed on both sides of the top of the outer shell 1. The mounting blocks 23 have mounting holes 24 inside. A mounting shaft 25 is rotatably installed between the two sets of mounting blocks 23. A shell cover 26 is fixedly installed on the side wall of the mounting shaft 25. As the antenna analyzer 4 continues to rise, the shell cover 26 can be opened to achieve the open state. Two sets of spiral springs 27 are installed at both ends of the mounting shaft 25. One end of the spiral spring 27 is fixedly connected to one end of the mounting shaft 25, and the other end of the spiral spring 27 is fixedly connected to the inner wall of the mounting hole 24. Under the elastic action of the spiral springs 27 on both sides, the mounting shaft 25 and the shell cover 26 can be driven to achieve the effect of rotation and closure.
[0027] During the use of the antenna receiving test device, the user first pulls the lifting rod 22 upwards, which moves a set of sliders 21 upwards along the sliding rod 20. This, in turn, moves the support base 2 and the antenna analyzer 4 upwards. As the antenna analyzer 4 continues to rise, the cover 26 can be opened, thus achieving the open state.
[0028] When the antenna analyzer 4 is fully exposed at its top, the adjusting groove 7 and the locking hole 12 are at the same level. Under the elastic action of the return spring 8, the locking rod 9 can be pushed into the locking hole 12, thus locking the support base 2 and the antenna analyzer 4 to their current positions. This design ensures the stability and accuracy of the antenna analyzer 4 during the testing process.
[0029] Furthermore, when the outer casing 1 is subjected to vibration, the multiple sets of guide columns 6 at the bottom of the shock absorber 3 slide along the multiple sets of L-shaped frames 5 at the top of the support base 2. During this process, the shock-absorbing damping ring 13 can slide along the guide columns 6 and generate damping friction, thereby absorbing vibration energy. At the same time, under the elastic action of the shock-absorbing spring 14 and the buffer spring 16, the impact of vibration on the device is further reduced, ensuring the accuracy and reliability of the test.
[0030] After testing, when storing the antenna analyzer 4, firstly, push the inner pressing rod 11, causing one end of the pressing rod 11 to press against one end of the locking rod 9. When one end of the locking rod 9 disengages from the locking hole 12, the support base 2 is unlocked. Simultaneously, under the weight of the antenna analyzer 4 itself, the support base 2 can move downwards along the slide rail 19, thereby storing the antenna analyzer 4 inside the outer casing 1, thus achieving a safety protection effect for the antenna analyzer 4. At this time, under the elastic action of the spiral springs 27 on both sides, the mounting shaft 25 and the casing cover 26 can rotate and close.
[0031] In summary, this antenna receiving capability testing device, through its unique component structure and working principle, enables the antenna analyzer 4 to achieve both convenient use and safe protection.
[0032] Through the above steps, when the antenna receiving test device is in use, firstly, pulling one side of the support base 2 upwards will cause the shock absorber base 3 and the antenna analyzer 4 to rise and move upwards, achieving the open state. When the top of the antenna analyzer 4 is fully exposed, the adjusting groove 7 and the locking hole 12 are at the same level. Under the elastic action of the return spring 8, the locking rod 9 can be pushed into the interior of the locking hole 12, causing the support base 2 and the antenna analyzer 4 to achieve the current position of locking. This design ensures the stability and accuracy of the antenna analyzer 4 during the test process. In addition, when the outer shell 1 is vibrated, the multiple sets of guide columns 6 at the bottom of the shock absorber base 3 slide along the multiple sets of L-shaped frames 5 at the top of the support base 2 for adjustment. During this process, the shock-absorbing damping ring 13 can slide along the guide columns 6, and Damping friction is generated to absorb vibration energy. Simultaneously, the elasticity of the damping spring 14 further reduces the impact of vibration on the device, ensuring the accuracy and reliability of the test. After the test, when storing the antenna analyzer 4, firstly, the inner side pushes the squeezing rod 11, causing one end of the squeezing rod 11 to press against one end of the locking rod 9. When one end of the locking rod 9 disengages from the locking hole 12, the support base 2 is unlocked. Simultaneously, under the weight of the antenna analyzer 4 itself, it can be stored inside the outer casing 1, thus achieving a safe protection effect for the antenna analyzer 4. In summary, this antenna receiving capability testing device, through its unique component structure and working principle, achieves convenient use and safe protection for the antenna analyzer 4.
[0033] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
