[0026] like Figure 1As shown, a wireless communication device of a preferred embodiment of the utility model comprises a wireless communication device 1, a lifting assembly 2 and a first antenna 4. A sleeve rod 3 is rotatably provided inside the wireless communication device 1. The lifting assembly 2 is used to drive the sleeve rod 3 to rise and fall. The first antenna 4 is arranged at the upper end of the sleeve rod 3. An enhanced antenna assembly 5 is arranged on the first antenna 4. At the same time, in view of the possible use scenarios of the wireless communication device, it is sometimes necessary to carry it. In order to facilitate the carrying of the wireless communication device, a shoulder strap 8 is also provided on the wireless communication device 1. Two shoulder straps 8 can be provided, corresponding to the shoulders of a person respectively, to ensure the comfort of the person.

[0027] The wireless communication device based on the above technical features can improve the signal receiving and sending strength of the wireless communication device itself by arranging the enhanced antenna assembly 5 on the first antenna 4; at the same time, by arranging the lifting assembly 2 to drive the lifting of the sleeve rod 3, and arranging the first antenna 4 at the upper end of the sleeve rod 3, the antenna has a lifting function. When the wireless signal reception and transmission are interfered, the first antenna 4 and the enhanced antenna assembly 5 can be controlled to rise, and the signal detection height can be adjusted, thereby improving the signal receiving and sending ability of the device; in addition, since the sleeve rod 3 is rotatably connected to the wireless communication device 1, the first antenna 4 and the enhanced antenna assembly 5 can be rotated horizontally by rotating the sleeve rod 3, and the signal search direction can be adjusted to improve the signal receiving and sending strength of the device, thereby avoiding the signal receiving and sending ability being affected by the harsh and remote working environment.

[0028] Please refer to the attached Figure 2 , 3 In this embodiment, the lifting assembly 2 includes a screw rod 21 disposed inside the wireless communication device 1, a connecting rod 22 is threadedly connected to the screw rod 21, and a driving rod 23 is connected to the other end of the connecting rod 22, and the driving rod 23 is inserted into the sleeve rod 3. Specifically, a bearing is provided inside the wireless communication device 1, and the screw rod 21 is connected to the bearing. The upper end of the screw rod 21 is exposed outside the wireless communication device 1 and is connected to a rotating wheel 24. When the sleeve rod 3 needs to be lifted or lowered, the rotating wheel 24 is rotated, and the rotating wheel 24 drives the screw rod 21 to rotate. Under the action of the screw rod 21, the connecting rod 22 drives the driving rod 23 to be lifted or lowered, and the driving rod 23 drives the sleeve rod 3 to be lifted or lowered.

[0029] At the same time, in order to realize the rotation of the sleeve rod 3, an adjustment component 6 for driving the sleeve rod 3 to rotate is provided between the drive rod 23 and the sleeve rod 3. Specifically, a limit block 61 is provided at the lower end of the sleeve rod 3, and when the sleeve rod 3 rises to the maximum height, the limit block 61 abuts against the inner wall of the wireless communication device 1, and the sleeve rod 3 is provided with an adjustment cavity extending to the lower end surface thereof, and the drive rod 23 is inserted into the adjustment cavity; the adjustment component 6 includes a spiral groove 62 provided on the inner wall of the adjustment cavity and a drive ball 63 matched with the spiral groove 62, and the drive ball 63 is fixedly connected to the drive rod and moves with the drive rod 23. Preferably, there are two spiral grooves 62 and two drive balls 63, which correspond to each other, and the two spiral grooves 62 are symmetrically arranged with respect to the center of the sleeve rod 3, and the two drive balls 63 are respectively guided and slidably located on the inner side of the two spiral grooves 62. When the driving rod 23 is controlled to move upward relative to the sleeve rod 3, the driving ball 63 on the top outer wall of the driving rod 23 can squeeze the spiral groove 62 correspondingly opened on the inner wall of the sleeve rod 3, so that the sleeve rod 3 drives the first antenna 4 and the enhanced antenna assembly 5 to rotate horizontally to adjust the signal search direction.

[0030] At the same time, in order to avoid interference between the driving rod 23 driving the sleeve rod 3 to rise and rotate, a support spring 7 is provided in the adjustment cavity, and the two ends of the support spring 7 are respectively in contact with the upper end surface of the driving rod 23 and the inner wall of the adjustment cavity. During operation, when the wireless signal reception and transmission are interfered, the screw rod 21 can be manually rotated to control the connecting rod 22 to drive the driving rod 23 fixed thereto to rise synchronously, and the driving rod 23 can push the sleeve rod 3 through the support spring 7 so that the two are in a relatively static state and move upward and rise synchronously, so as to control the first antenna 4 and the enhanced antenna assembly 5 to rise, adjust the signal detection height, and improve the signal reception and transmission capability of the device;

[0031] The two limit blocks 61 symmetrically fixed on the outer wall of the bottom of the sleeve rod 3 can limit the lifting range of the sleeve rod 3. When the sleeve rod 3 is raised to the highest point, the screw rod 21 is continuously rotated to control the driving rod 23 to move upward. At this time, the driving rod 23 moves upward relative to the sleeve rod 3 in a stationary state, and squeezes the support spring 7 to compress it, so that the driving ball 63 on the outer wall of the top of the driving rod 23 squeezes the spiral groove 62 correspondingly opened on the inner wall of the sleeve rod 3, so that the sleeve rod 3 drives the first antenna 4 and the enhanced antenna assembly 5 to rotate horizontally, so as to adjust the signal search direction. When the driving 23 drives the sleeve rod 3 to descend, the driving ball 63 first descends to the lowest end of the spiral groove 62, and then drives the sleeve rod 3 to descend.

[0032] Please refer to the attached Figure 1 , 4In this embodiment, the enhanced antenna assembly 5 includes two second antennas 51 arranged opposite to each other. The two second antennas 51 are respectively arranged on both sides of the first antenna 4 and can be adjusted in angle relative to the first antenna 4. Therefore, when the wireless signal transmission and reception are interfered, the angle between the second antenna 51 and the first antenna 4 can be adjusted to achieve the adjustment of the signal search angle, so as to facilitate the signal search and enhance the transmission and reception strength of the radio signal.

[0033] Specifically, the enhanced antenna assembly 5 further includes a first crossbar 52 and a second crossbar 53, the middle parts of the first crossbar 52 and the second crossbar 53 are both sleeved on the first antenna 4, and the second crossbar 53 is located below the first crossbar 52 and can move along the axial direction of the first antenna 4, and a movable rod 54 is inserted in the second crossbar 53 so as to be movable along its axial direction, and the free ends of the movable rod 54 and the first crossbar 52 located on the same side are connected to a second antenna 51. When the angle of the second crossbar 53 needs to be adjusted, the bottoms of the two second antennas 51 are squeezed to make them close to each other, and at this time, the movable rod 54 shrinks toward the inside of the second crossbar 53, and the second crossbar 53 slides upward along the first antenna 4, so that the second antenna 51 can be controlled to rotate vertically to adjust the signal search angle. A movable seat 55 is provided on the second antenna 51, and the movable rod 54 and the first crossbar 52 are both hinged to the corresponding movable seat 55.

[0034] At the same time, in order to ensure the stability of the second antenna 51 after the angle is adjusted, a positioning bolt 56 is threadedly connected to the second crossbar 53. When the positioning bolt 56 abuts against the movable rod 54, the position of the movable rod 54 relative to the second crossbar 53 is fixed. When the angle needs to be adjusted, the positioning bolt 56 is first loosened, the second antenna 51 is squeezed, and the movable rod 54 moves relative to the second crossbar 53. After adjusting to the required position, the positioning bolt 56 can be tightened, so that the positioning bolt 56 is used to position the second crossbar 53 and the movable rod 54, so as to facilitate locking the tilt state of the second antenna 51.

[0035] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principle of the present invention. These improvements and substitutions should also be regarded as the protection scope of the present invention.
