Description
Technical Field
[0001] This invention belongs to the field of antennas, specifically a portable self-tracking telemetry antenna. Background Technology
[0002] Telemetry antennas are used in systems such as in-vehicle navigation, wireless TV, and the Internet of Things for remote control and telemetry. One common type of telemetry antenna is a rod-shaped omnidirectional antenna.
[0003] A patent application with publication number CN108598706B discloses an omnidirectional antenna, comprising: a dielectric substrate, a first antenna body, a second antenna body, a loading resistor, and a feed connector. The antenna body includes a conductor strip and a radiating element, with the radiating element disposed between two adjacent conductor strips. A loading resistor and a feed connector are provided between the first antenna body and the second antenna body. This invention can effectively broaden the antenna's operating frequency band and improve the antenna's operating bandwidth.
[0004] The above-mentioned technical solutions still have some problems in practical use. To obtain better signal reception, other objects should be avoided as much as possible on the outside of the antenna body. Existing omnidirectional telemetry antennas mainly consist of a mounting base and an exposed antenna body. The outer shell of the antenna body is mostly made of fiberglass or plastic, which can provide some protection. However, for a straight-rod portable telemetry antenna, the antenna body is relatively long. During handheld walking or transport by loading the antenna into a vehicle, the antenna may come into contact with other objects, resulting in compression and collision, which could lead to antenna breakage. Therefore, antenna protection is necessary. However, the conventional protection solution is to install a fixed or retractable protective shell on the outside of the antenna to fix it. The protective shell of the structure may affect the antenna's signal reception. Traditional telescopic protective shells have multiple telescopic rods. Due to the long length of the antenna and the need to minimize the space occupied around the antenna during retraction, the telescopic rods need to be designed as multiple shorter rods. This increases the number of short rods within each telescopic rod, and fixing each short rod within each telescopic rod after it has been extended is also more cumbersome, greatly increasing the workload. Therefore, the traditional telescopic rod structure is inconvenient to use in portable telemetry antennas. How to effectively protect the long rod-shaped telemetry antenna during carrying without affecting the antenna's signal reception during operation is a difficult problem for portable telemetry antennas, and the above-mentioned technical solutions have not effectively solved this problem.
[0005] Therefore, the present invention provides a portable self-tracking telemetry antenna. Summary of the Invention
[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.
[0007] The technical solution adopted by this invention to solve its technical problem is as follows: A portable self-tracking telemetry antenna according to this invention includes a base and an antenna body, wherein the antenna body is fixedly connected to the base, and further includes:
[0008] Several protective rods are disposed at the top of the base, the protective rods being telescopic structures, and the protective rods are evenly distributed in a ring around the outer side of the antenna body; and
[0009] A support ring is connected to the top of several of the protective rods, and the support ring is sleeved on the outside of the antenna body.
[0010] Specifically, in the initial state and during installation and use, the protective rod is in a retracted state, and the support ring is attached to the top of the base. This reduces space occupation, and the base and support ring form an integral protective cover, which covers and protects the protective rod and other structures. In addition, it ensures that the antenna body is unobstructed on all sides, reducing the interference that the protective device may cause to the antenna body during signal reception.
[0011] When carrying the antenna, extend the protective rods upwards and simultaneously push the support rings upwards. After all the protective rods are open, the multiple protective rods and the support rings form a cage. The tops of the multiple protective rods are connected as one unit through the support rings, which can improve the overall structural stability of the cage. The cage is placed on the outside of the antenna body to protect the antenna body and improve the problem that the antenna body may be broken or damaged due to compression during carrying.
[0012] Preferably, the protective rod includes:
[0013] A box body fixed to the base;
[0014] A telescopic rod installed inside the box, wherein the telescopic rod is an elastic telescopic bar;
[0015] A torsion cap fixed to the top of the telescopic rod, the torsion cap being rotatably connected to the bottom end of the support ring; and
[0016] A locking pin is used to secure the telescopic rod inside the housing.
[0017] Specifically, the elastic telescopic rod can be made of elastic steel ruler or plastic with telescopic function, similar to the Magic Golden Cudgel or Magic Telescopic Rod. A limit ring is set on the torsion cap, so that the torsion cap can only rotate within the support ring. In the initial state, the telescopic rod is rolled up in the box and fixed by a locking pin to prevent the telescopic rod from extending outward. When unfolded, the locking pin is pulled open, and the telescopic rod can extend outward while rotating. The telescopic rod will maintain a stable elongation state under its own elasticity, thus keeping the cage structurally stable. This spirally extending telescopic rod structure is lighter than the traditional straight-tube telescopic rod.
[0018] Preferably, the locking pin is slidably mounted on the housing, and the device further includes a safety mechanism, the safety mechanism comprising:
[0019] A slot is provided on the side of the twist cap ring;
[0020] A reset spring is used to drive the locking pin into the slot;
[0021] A pressure ring that is movably mounted on the support ring; and
[0022] Several top plates are fixed to the inner wall of the pressure ring. After the pressure ring rotates, the top plates push the locking pin away from the twist cap.
[0023] Specifically, the pressure ring can rotate within the support ring; in the initial state, the telescopic rod is compressed and retracted into the box. At this time, the locking pin on the box is inserted into the slot in the twist cap, thereby locking the telescopic rod to prevent it from popping out.
[0024] When protecting the antenna body, the pressure ring is rotated. After the pressure ring rotates, multiple top plates simultaneously push multiple locking pins to move, causing the locking pins to disengage from the slots. Then, the telescopic rod can pop outward, realizing the function of simultaneously releasing the locking state of multiple telescopic rods. The operation is quick and convenient.
[0025] Preferably, the locking pin includes a vertical plate and a top horizontal plate, the top horizontal plate being inserted into the locking slot, and the top of the top horizontal plate having a slope.
[0026] Specifically, when retracting the telescopic rod, the rod is pressed into the housing. After the bottom end of the twist cap contacts the ramp of the top horizontal plate, it automatically squeezes the locking pin outward until the slot in the twist cap moves down to be flush with the top horizontal plate. Then, the top horizontal plate automatically inserts into the slot under the action of the return spring, completing the automatic locking function of the telescopic rod.
[0027] Preferably, the top plate is L-shaped, the side wall of the top plate is provided with a slope, and the slope is located inside the vertical plate of the latch, and the top plate and the top horizontal plate of the latch are staggered vertically.
[0028] Specifically, when the telescopic rod is extended, the pressure ring is rotated. After the pressure ring rotates, the top plate rotates accordingly and pushes the locking pin outward, releasing the locking state of the telescopic rod.
[0029] Preferably, it further includes a retraction mechanism, the retraction mechanism comprising:
[0030] The toothed ring fixed to the side of the torsion cap ring; and
[0031] A spring assembly is installed at the bottom end of the support ring, and the spring assembly is provided with a knob that can engage with the toothed ring for transmission.
[0032] Specifically, based on common sense, during the retraction of the flexible steel ruler, it is necessary to press down on the steel ruler while rotating its top. This solution achieves this operation by setting up a spring assembly. The spring assembly can be tightened and energy stored by rotating the knob. When the telescopic rod is pressed into the box, the spring assembly is activated to release energy. The spring assembly drives the knob to rotate, and the rotating knob engages with the gear ring, thereby driving the torsion cap to rotate. Therefore, simply squeezing the support ring to move it towards the box is enough to complete the automatic retraction of the flexible steel ruler.
[0033] Preferably, a lifting rod is fixedly connected to the top end of the spring assembly, the lifting rod is movably inserted into the inside of the support ring, and the top end of the lifting rod is movably engaged with the pressure ring.
[0034] Specifically, the lifting rod can slide up and down inside the support ring. A limit ring is provided on the lifting rod, so that the pressure ring can drive the lifting rod to move up and down together, and the pressure ring can rotate independently. In the initial state, the mainspring assembly is located above the toothed ring, and the two are staggered vertically, with one side tightening the mainspring assembly independently. When retracting the telescopic rod, the mainspring assembly is moved downward so that the mainspring assembly is horizontally aligned and in contact with the toothed ring, so that the mainspring assembly can drive the toothed ring and the torsion cap to rotate after releasing energy.
[0035] Preferably, the recovery mechanism further includes:
[0036] A check pawl is provided at the bottom end of the support ring, the check pawl being used to lock the knob, and the check pawl being located above the toothed ring; and
[0037] A support spring is used to push the pressure ring upwards, and after the mainspring assembly moves upwards, it causes the knob to align horizontally with the toothed ring.
[0038] Specifically, the pressure ring can rotate and move up and down inside the support ring, and the check pawl prevents the knob from turning back. In the initial state, the support spring pushes the pressure ring upward, so that the mainspring assembly is above the gear ring. At this time, the knob and the check pawl are horizontally aligned. When retracting the telescopic rod, pressing down on the pressure ring causes it to move downward first inside the support ring, and then the pressure ring drives the support ring to move downward together. During the downward movement of the pressure ring inside the support ring, it drives the mainspring assembly to move downward until it is horizontally aligned with the gear ring, and the knob and the check pawl are vertically offset. After being freed from the restraint of the check pawl, the mainspring assembly can release energy and drive the gear ring to rotate, realizing the automatic engagement function of the mainspring assembly and the gear ring. The operation is simple and convenient.
[0039] Preferably, the recovery mechanism further includes:
[0040] A support plate fixed to the bottom end of the support ring;
[0041] Rotate the sleeve mounted on the support plate, and the knob is movably inserted into the sleeve;
[0042] A rack plate fixed to the outside of the housing; and
[0043] A transmission gear assembly, wherein the sleeve engages with the rack plate via the transmission gear assembly.
[0044] Specifically, the sleeve rotates horizontally, and a rod inserted into the sleeve is fixed to the bottom of the knob, causing the knob to rotate along with the sleeve. The knob can also slide up and down relative to the sleeve. The transmission gear assembly includes two meshing bevel gears, bevel gear one and bevel gear two. Bevel gear one is fixed to the sleeve and is offset from the rack plate. Bevel gear two is rotatably mounted on the support plate and meshes with the rack plate. In the initial state, when the telescopic rod is retracted into the housing, bevel gear two is in contact with the rack plate, and the spring assembly is offset from the gear ring. When the latch is pulled open and the telescopic rod moves outward, bevel gear two also moves upward along with the support ring. At this time, because bevel gear two is meshing with the rack plate, bevel gear two rotates, driving the bevel gear two to rotate. The first sleeve rotates, causing the knob to rotate, thus automatically tightening the spring assembly. The second bevel gear continues to move upward and separates from the rack plate. During this process, the check pawl remains in contact with the knob to prevent it from rotating back. When retracting the telescopic rod, the pressure ring is pressed down. The pressure ring first moves the spring assembly and the knob downward, so that the knob moves down to be horizontally aligned with the gear ring and offset from the check pawl. Then the spring assembly can rotate back, causing the gear ring and the torsion cap to rotate. The pressure ring continues to be pressed down, causing the telescopic rod to move downward. During the downward movement, the top of the telescopic rod rotates automatically, allowing the telescopic rod to be screwed into the housing, completing the telescopic rod retraction operation. The rotation and downward movement of multiple telescopic rods can be performed simultaneously and automatically, simplifying the operation and making it convenient to use.
[0045] Preferably, the toothed ring is located above the slot, and the spring assembly and the locking pin are located on both sides of the housing.
[0046] Specifically, the staggered arrangement ensures that the movement of the spring assembly and the locking pin do not interfere with each other, and the compact structure reduces space occupation.
[0047] The beneficial effects of this invention are as follows:
[0048] 1. The portable self-tracking telemetry antenna of the present invention features a retractable protective rod and a support ring on its base. During use after antenna installation, the protective rod is retracted, and the support ring rests against the top of the base. This reduces space occupation, and the base and support ring form a unified protective cover, shielding the protective rod and other structures within it. This also ensures that the antenna body remains unobstructed, reducing potential interference with the received signal. When carrying the antenna, all the protective rods are extended upwards, forming a cage with the support ring. The tops of the multiple protective rods are connected by the support ring, improving the overall structural stability of the cage. The cage covers the outside of the antenna body, protecting it.
[0049] 2. The portable self-tracking telemetry antenna of the present invention has a protective rod made of elastic telescopic rod. After the locking pin is pulled open, the telescopic rod automatically pops out and its shape is stable, which can ensure the structural stability of the cage. After rotating the pressure ring, multiple locking pins are pulled open at the same time, and multiple telescopic rods pop out automatically and synchronously, which is convenient to operate.
[0050] 3. The portable self-tracking telemetry antenna of the present invention, since the elastic telescopic rod needs to be pressed down and rotated at the end during the retraction process, achieves the function of automatically tightening the spring assembly during the extension of the telescopic rod and automatically driving the end of the telescopic rod to rotate during the retraction process by setting up a spring assembly and a transmission gear assembly, in conjunction with a pressure ring that can slide in the support ring. The antenna has a simple and compact overall structure, operates automatically, and is easy to operate. At the same time, the gear transmission assembly also plays a role in slowing down the extension speed of the telescopic rod, thereby protecting the operator. Attached Figure Description

[0061] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.
[0062] Example 1
[0063] like Figure 1-9 As shown in the figure, a portable self-tracking telemetry antenna according to an embodiment of the present invention includes a base 1 and an antenna body 2, wherein the antenna body 2 is fixedly connected to the base 1, and further includes:
[0064] Several protective rods 3 are disposed at the top of the base 1. The protective rods 3 are telescopic structures and are evenly distributed in a ring around the outer side of the antenna body 2; and
[0065] A support ring 4 is connected to the top of several of the protective rods 3, and the support ring 4 is sleeved on the outside of the antenna body 2.
[0066] Specifically, the antenna body 2 can be a NOGPS HX-A85 telemetry antenna, a NOGPS HX-D63 suction cup antenna, or a Huatong Jiaye HT556V4AC series omnidirectional antenna; in the initial state and during installation and use, the protective rod 3 is in a retracted state, and the support ring 4 is attached to the top of the base 1, such as... Figure 1 As shown, this design reduces space usage, and the base 1 and support ring 4 form an integrated protective cover that shields the protective rod 3 and other structures. In addition, it ensures that the antenna body 2 is unobstructed from all sides, reducing the potential interference of the protective device on the received signals during the operation of the antenna body 2.
[0067] When carrying the antenna, extend and unfold the protective rod 3 upwards. Simultaneously, the protective rod 3 pushes the support ring 4 upwards. After all the protective rods 3 are unfolded, the multiple protective rods 3 and the support ring 4 form a cage, such as... Figure 9 As shown, the tops of multiple protective rods 3 are connected as one unit by support rings 4, which can improve the overall structural stability of the net cage. The net cage is placed on the outside of the antenna body 2 to protect the antenna body 2 and improve the problem that the antenna body 2 may be broken or damaged due to squeezing during carrying.
[0068] like Figure 2-6 As shown, the protective rod 3 includes:
[0069] The box 31 is fixed to the base 1;
[0070] A telescopic rod 32 is installed inside the housing 31; the telescopic rod 32 is an elastic telescopic rod.
[0071] A torsion cap 33 is fixed to the top end of the telescopic rod 32, and the torsion cap 33 is rotatably connected to the bottom end of the support ring 4; and
[0072] The locking pin 34 is used to fix the telescopic rod 32 inside the box 31.
[0073] Specifically, the elastic telescopic rod can be made of elastic steel ruler or plastic with telescopic function, similar to the Magic Golden Cudgel or Magic Telescopic Rod. Its retracted length can be as short as 4 cm, while its extended length can be as long as 1.5 meters, which is longer than the length of a typical portable telemetry antenna. It can also maintain its shape stability after extension, meeting the needs of antenna protection. A limit ring is provided on the twist cap 33, so that the twist cap 33 can only rotate within the support ring 4. In the initial state, the telescopic rod 32 is rolled up in the box 31 and fixed by the locking pin 34 to prevent the telescopic rod 32 from extending outward. When unfolded, the locking pin 34 will move, and the telescopic rod 32 can extend outward while rotating. The telescopic rod 32 will maintain a stable extension state under its own elasticity, thus keeping the cage structurally stable. In the long-distance telescopic stroke environment, this spirally extending telescopic rod 32 structure is lighter than the traditional straight cylindrical telescopic rod 32.
[0074] like Figure 4-5 As shown, the locking pin 34 is slidably mounted on the housing 31, and the device also includes a safety mechanism 5, which comprises:
[0075] A slot 51 is provided on the ring side of the twist cap 33;
[0076] A return spring 52 is used to drive the locking pin 34 into the slot 51;
[0077] The pressure ring 53 is movably mounted on the support ring 4; and
[0078] Several top plates 54 are fixed to the inner wall of the pressure ring 53. After the pressure ring 53 rotates, the top plates 54 push the locking pin 34 away from the twist cap 33.
[0079] Specifically, the pressure ring 53 can rotate within the support ring 4; in the initial state, the telescopic rod 32 is compressed and retracted within the box 31. At this time, the locking pin 34 on the box 31 is inserted into the slot 51 in the twist cap 33, thereby locking the telescopic rod 32 to prevent it from popping out.
[0080] When protecting the antenna body 2, the pressure ring 53 is rotated. After the pressure ring 53 rotates, multiple top plates 54 simultaneously push multiple locking pins 34 to move, causing the locking pins 34 to disengage from the slots 51. Then, the telescopic rod 32 can pop outward, realizing the function of simultaneously releasing the locking state of multiple telescopic rods 32. The operation is quick and convenient.
[0081] like Figure 4-5 As shown, the locking pin 34 includes a vertical plate and a top horizontal plate. The top horizontal plate is inserted into the locking groove 51, and the top of the top horizontal plate is provided with a slope.
[0082] Specifically, when retracting the telescopic rod 32, the telescopic rod 32 is pressed into the box 31. After the bottom end of the twist cap 33 contacts the top horizontal plate slope, it automatically squeezes the locking pin 34 to move outward until the locking groove 51 in the twist cap 33 moves down to be flush with the top horizontal plate. Then, the top horizontal plate is automatically inserted into the locking groove 51 under the action of the return spring 52, thus completing the automatic locking function of the telescopic rod 32.
[0083] like Figure 8 As shown, the top plate 54 is L-shaped, and the side wall of the top plate 54 is provided with a slope. The slope is located inside the vertical plate of the latch 34, specifically between the inner wall of the twist cap 33 and the vertical plate of the latch 34. The top plate 54 and the top horizontal plate of the latch 34 are staggered vertically.
[0084] Specifically, when the telescopic rod 32 is extended, the pressure ring 53 is rotated. After the pressure ring 53 rotates, the top plate 54 rotates accordingly and pushes the locking pin 34 outward, releasing the locked state of the telescopic rod 32.
[0085] like Figure 4-5 As shown, it also includes a retraction mechanism 6, which includes:
[0086] The toothed ring 61 fixed to the annular side of the torsion cap 33; and
[0087] A spring assembly 62 is installed at the bottom of the support ring 4. A knob 621 is provided in the spring assembly 62. The knob 621 can engage with the toothed ring 61 for transmission.
[0088] Specifically, during the retraction process of the elastic steel ruler, it is necessary to press down on the steel ruler while rotating the top of the steel ruler. This solution achieves this operation by setting up a spring assembly 62. The spring assembly 62 can be tightened and energy stored by rotating the knob 621. When the telescopic rod 32 is pressed into the box 31, the spring assembly 62 is activated to release energy. The spring assembly 62 drives the knob 621 to rotate. The rotating knob 621 engages with the toothed ring 61, thereby driving the torsion cap 33 to rotate. Therefore, the automatic retraction operation of the elastic steel ruler can be completed simply by squeezing the support ring 4 towards the box 31.
[0089] like Figure 4-5 As shown, a lifting rod 622 is fixedly connected to the top of the spring assembly 62. The lifting rod 622 is movably inserted into the inside of the support ring 4, and the top of the lifting rod 622 is movably engaged with the pressure ring 53.
[0090] Specifically, the lifting rod 622 can slide up and down inside the support ring 4. A limit ring is provided on the lifting rod 622, so that the pressure ring 53 can drive the lifting rod 622 to move up and down together, and the pressure ring 53 can rotate independently. In the initial state, the spring assembly 62 is located above the toothed ring 61, and the two are staggered vertically, with the spring assembly 62 being tightened independently on one side. When the telescopic rod 32 is retracted, the spring assembly 62 is moved downward so that the spring assembly 62 is horizontally aligned with the toothed ring 61 and engages with it, so that the spring assembly 62 can drive the toothed ring 61 and the torsion cap 33 to rotate after releasing energy.
[0091] like Figure 4-5 As shown, the retraction mechanism 6 further includes:
[0092] A pawl 63 is provided at the bottom end of the support ring 4, the pawl 63 is used to lock the knob 621, and the pawl 63 is located above the toothed ring 61; and
[0093] The support spring 64 is used to push the pressure ring 53 upward. After the mainspring assembly 62 moves upward, it drives the knob 621 to be horizontally aligned with the toothed ring 61.
[0094] Specifically, the pressure ring 53 can rotate and move up and down relative to the support ring 4, and the check pawl 63 is used to prevent the knob 621 from turning back. In the initial state, the support spring 64 pushes the pressure ring 53 upward, so that the mainspring assembly 62 is above the toothed ring 61. At this time, the knob 621 and the check pawl 63 are horizontally aligned. When the telescopic rod 32 is retracted, the pressure ring 53 is pressed down. The pressure ring 53 moves downward first, and then the pressure ring 53 drives the support ring 4 to move downward together. During the downward movement of the pressure ring 53 in the support ring 4, it drives the mainspring assembly 62 to move down until it is horizontally aligned with the toothed ring 61 and engages with it. The knob 621 and the check pawl 63 are vertically offset. After the constraint of the check pawl 63 is removed, the mainspring assembly 62 can release energy and drive the toothed ring 61 to rotate, realizing the automatic engagement function of the mainspring assembly 62 and the toothed ring 61. The operation is simple and convenient.
[0095] like Figure 4-5 As shown, the retraction mechanism 6 further includes:
[0096] A support plate 65 is fixed to the bottom end of the support ring 4;
[0097] Rotate the sleeve 66 mounted on the support plate 65, and the knob 621 is movably inserted into the sleeve 66;
[0098] The rack plate 67 fixed to the outside of the housing 31; and
[0099] The sleeve 66 is engaged with the rack plate 67 via the transmission gear assembly 68.
[0100] Specifically, the sleeve 66 can rotate horizontally, and the bottom end of the knob 621 is fixedly connected to a rod inserted into the sleeve 66, so that the rotation of the sleeve 66 drives the knob 621 to rotate together, and the knob 621 can slide up and down relative to the sleeve 66; the transmission gear assembly 68 includes a bevel gear one and a bevel gear two that mesh with each other. The bevel gear one is fixedly connected to the sleeve 66 and is offset from the rack plate 67. The bevel gear two is rotatably mounted on the support plate 65 and meshes with the rack plate 67; in the initial state, the telescopic rod When the spring assembly 62 retracts into the housing 31, the second bevel gear contacts the rack plate 67, and the spring assembly 62 and the gear ring 61 are vertically offset. As the locking pin 34 is pulled open and the telescopic rod 32 moves outward, the second bevel gear also moves upward along with the support ring 4. At this time, because the second bevel gear meshes with the rack plate 67, the second bevel gear rotates, causing the first bevel gear and the sleeve 66 to rotate. The sleeve 66 then rotates the knob 621, completing the automatic tightening operation of the spring assembly 62. The second bevel gear continues to move upward and then contacts the rack plate... 67 separates. During this process, the check pawl 63 remains in contact with the knob 621 to prevent the knob 621 from rotating. When the telescopic rod 32 retracts, the pressure ring 53 is pressed down. The pressure ring 53 first moves the mainspring assembly 62 and the knob 621 downwards, so that the knob 621 moves down to be horizontally aligned with the toothed ring 61 and misaligned with the check pawl 63. Then the mainspring assembly 62 can rotate, driving the toothed ring 61 and the torsion cap 33 to rotate. The pressure ring 53 continues to be pressed down, causing the telescopic rod 32 to move downwards. During the downward movement... The top of the telescopic rod 32 rotates automatically, allowing it to be screwed into the housing 31, thus completing the retraction operation. Furthermore, the rotation and downward movement of multiple telescopic rods 32 can be performed synchronously and automatically, simplifying the operation and making it convenient to use. Additionally, when the protective rod 3 is made of a highly elastic steel ruler, the speed at which the elastic steel ruler pops outward during extension is too fast. The transmission gear assembly 68 can also act as a reduction gear to slow down the pop-out speed of the elastic steel ruler, thus protecting the operator.
[0101] Example 2
[0102] like Figure 5 As shown in the comparative embodiment one, another embodiment of the present invention is as follows: the toothed ring 61 is located above the slot 51, and the spring assembly 62 and the locking pin 34 are located on both sides of the housing 31 respectively.
[0103] Specifically, the staggered arrangement ensures that the operation of the spring assembly 62 and the locking pin 34 do not interfere with each other, and the compact structure reduces space occupation.
[0104] Working principle: In the initial state, the support ring 4 is attached to the top of the base 1, and multiple telescopic rods 32 are retracted into the box 31, with the locking pins 34 inserted into the slots 51 to fix and lock the telescopic rods 32. When carrying the antenna for transportation or travel, the pressure ring 53 is rotated first. After the pressure ring 53 rotates, multiple top plates 54 simultaneously push multiple locking pins 34 to move, causing the locking pins 34 to disengage from the slots 51. Then, the telescopic rods 32 can pop up. During the upward popping of the telescopic rods 32, the second bevel gear also moves upward with the support ring 4. At this time, since the second bevel gear meshes with the rack plate 67, the second bevel gear rotates, driving the first bevel gear and the sleeve 66 to rotate. The sleeve 66 drives the knob 621 to rotate, completing the automatic tightening operation of the spring assembly 62. After the second bevel gear continues to move upward, it separates from the rack plate 67. During this process, the anti-return pawl 63 is always in contact with the knob 621 to prevent the knob 621 from rotating back.
[0105] After all the telescopic rods 32 pop up, the multiple telescopic rods 32 and the support ring 4 form a net cage. The net cage is placed on the outside of the antenna body 2 to protect the antenna body 2 from being directly squeezed or touched.
[0106] When retracting the telescopic rod 32, the pressure ring 53 is pressed down. The pressure ring 53 first drives the mainspring assembly 62 and the knob 621 to move down, so that the knob 621 moves down to be horizontally aligned with the toothed ring 61 and misaligned with the anti-return pawl 63. Then the mainspring assembly 62 can automatically rotate, driving the toothed ring 61 and the torsion cap 33 to rotate. The pressure ring 53 continues to be pressed down, and the pressure ring 53 drives the support ring 4 and the telescopic rod 32 to move down together. During the downward movement, the mainspring assembly 62 drives the top of the telescopic rod 32 to rotate, thereby rotating and pressing the telescopic rod 32 into the housing 31, completing the retraction operation of the telescopic rod 32. Moreover, the retraction operation of multiple telescopic rods 32 is carried out simultaneously and automatically, simplifying the operation and making it convenient to use.
