Detailed Description
The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making clear and defining the scope of the present invention.
Referring to the drawings, a pipe shaft comprises a pipe shaft body 11, a plugboard 2 and a gasket 3.
The pipe shaft body 11 is a straight rod, one end of the pipe shaft body 11 is provided with a pipe shaft head 12, and the pipe shaft body 11 and the pipe shaft head 12 are of hollow structures. In order to make the stress of each part of the pipe shaft head 12 uniform, the center line of the pipe shaft head 12 and the center line of the pipe shaft body 11 are on the same line; the vertical cross-sectional area of the pipe shaft head 12 is larger than that of the pipe shaft body 11, namely, the pipe shaft head 12 forms a convex block in the radial direction of the pipe shaft body 11, so that the pipe shaft is prevented from slipping in the rotating process.
The plugboard 2 is used for fixing the tube shaft and simultaneously plays a role in connecting the tube shaft with an external device. The plugboard 2 is provided with a jack 21 for the tube shaft body 11 to pass through, so that the antenna 5 can conveniently pass through the tube shaft body 11.
Further, in order to better realize the function of rotation fixation, fan-shaped protruding blocks 13 are axially arranged on the pipe shaft head 12 in an array manner, and grooves are formed between two adjacent fan-shaped protruding blocks 13, namely, concave-convex surfaces are formed on the periphery of the pipe shaft head 12. The shape of the insertion hole 21 is matched with the shape of the axle head 12, namely, a concave-convex opening 212 is formed on the plugboard 2. When the axle head 12 passes through the plugboard 2, the fan-shaped protruding block 13 on the axle head 12 corresponds to the notch 211 of the plugboard 21 in the plugboard 2, and the groove on the axle head 12 corresponds to the convex opening 212 of the plugboard 21 in the plugboard 2.
Further, the diameter of the boss 212 of the insertion hole 21 can be made to coincide with the diameter of the spool body 11, and the insert plate 2 catches the spool body 11 when the spool body 11 passes through the insertion hole 21. The recess 211 of the receptacle 21 is slightly larger in shape and size than the scallop projections 13 on the axle head 12 to facilitate the passage of the scallop projections 13.
Further, the fan-shaped protruding block 13 includes a fan-shaped protruding block first end 131 and a fan-shaped protruding block second end 132, the height of the fan-shaped protruding block first end 131 is smaller than the height of the fan-shaped protruding block second end 132, the fan-shaped protruding block second end 132 contacts with the pipe shaft head 12, that is, the cross section of the fan-shaped protruding block 13 is similar to a trapezoid, so that the pipe shaft head 12 is smoothly guided in the process of passing through the plugboard 2, the operation difficulty is reduced, and the working efficiency is improved.
Further, the number of the fan-shaped protruding blocks 13 is 4-6, the joint of each fan-shaped protruding block 13 and the pipe shaft head 12 is 1/6-1/10 of the circumference of the pipe shaft head 12, the longer arc length of the fan-shaped protruding blocks 13 is prevented from generating cracks, the processing difficulty caused by the shorter arc length of the fan-shaped protruding blocks 13 is reduced, and therefore the fan-shaped protruding blocks 13 are guaranteed to have enough strength, and the reliability of the corresponding service life is achieved.
The gasket 3 is clamped on the pipe shaft body 11 and is positioned between the pipe shaft head 12 and the plugboard 2, so that the defect of machining of the pipe shaft head 12 and the plugboard 2 is overcome, the connecting effect is better, the pipe shaft head 12 is fixed, and the plugboard 2 is protected to a certain extent.
Furthermore, the gasket 3 is an E-shaped gasket 3, the E-shaped gasket 3 has high pressure bearing capacity, good rebound resilience and sealing performance, and long service life in the use environment of periodical axial deformation of the sealing groove such as a tube shaft.
Further, the tube shaft body 11 and the tube shaft head 12 are made of plastic. The materials of the tube shaft body 11 and the tube shaft head 12 can be preferably polyoxymethylene resin, namely POM (Polyoxymethylene) plastic, which has excellent friction resistance. Because the rotation frequency of the tube shaft body 11 and the tube shaft head 12 is high, the material of the tube shaft body and the tube shaft head is polyoxymethylene resin, so that the service life can be effectively prolonged.
An external antenna comprises a housing 4 and the tube shaft. The housing 4 includes a first housing 41 and a second housing 42, and a receiving cavity is provided in the first housing 41 and the second housing 42 for placing the antenna 5, so that the space occupation rate is reduced by using the existing limited space. The contact surfaces of the first housing 41 and the second housing 42 are inclined surfaces, and the pipe shaft is provided on the contact surfaces of the first housing 41 and the second housing 42, and the first housing 41 and the second housing 42 are rotatably connected by the pipe shaft.
Further, in order to improve the stability of the external antenna, the included angle between the inclined plane and the horizontal plane is set to be 15-45 degrees.
When the pipe shaft is mounted in the outer housing 4, the first housing 41 and the second housing 42 correspond to the insert plate 2, and the first housing 41 and the second housing 42 are provided with the insertion holes 21. The antenna 5 passes through the tube axis, thereby realizing the transition of the antenna 5 in the first housing 41 and the second housing 42. The first housing 41 and the second housing 42 rotate about the tube axis as a fulcrum, and the contact surfaces of the first housing 41 and the second housing 42 are provided as inclined surfaces, so that switching between the first housing 41 and the second housing 42 on the same plane or perpendicular to each other can be achieved.
In actual use, the first housing 41 and the second housing 42 are placed in proper positions, and the antenna 5 passes through the tube shaft body 11 and the shaft head. The tube shaft body 11 and the shaft head pass through the contact surfaces of the first shell 41 and the second shell 42, and the tube shaft body 11 is rotated by a certain angle, so that the fan-shaped protruding blocks 13 are staggered with the notches 211 on the insertion holes 21. The gasket 3 is clamped on the pipe shaft body 11 and is attached to the pipe shaft head 12, and the gasket 3 is in interference fit with the pipe shaft body 11 to ensure the strength of the pipe shaft. At this time, the axes of the first housing 41 and the second housing 42 are on the same horizontal plane, i.e., the first housing 41 and the second housing 42 are both in the horizontal position. After the first casing 41 or the second casing 42 is rotated 180 ° around the tube axis, the first casing 41 and the second casing 42 are in a relatively vertical position, and the external antenna realizes the functions of receiving and transmitting signals.
In order to detect the reliability of the external antenna provided with the tube shaft, the service life of the external antenna is tested. 300 external antennas provided with the tube shafts are adopted, the external antennas are divided into 3 groups, 100 external antennas are respectively rotated 100 times, 300 times and 500 times, and the rotation function and the electric function of the external antennas are detected. The rotation experiment is to rotate the first external antenna by 180 degrees and reset the first external antenna, and the rotation experiment is one rotation experiment. The rotation function refers to a normal rate of the rotation function of the tube shaft after 100, 300, and 500 rotations.
The electrical function means that the standing wave value is smaller than 1.8 (short for low frequency band) when the wireless receiving frequency band is 2.4-2.5 GHz, and the standing wave value is smaller than 3 (short for high frequency band) when the wireless receiving frequency band is 5.1-5.8 GHz, and the signal line of the external antenna is not broken under the two conditions, and the electrical function abnormality is not caused. The electrical function is evaluated by a Voltage Standing Wave Ratio (VSWR), which is the ratio of the voltage peak value to the voltage valley value of a standing wave, which can be calculated by the modulus of reflection coefficient: vswr= (1+ reflectance mode)/(1-reflectance mode). And the ratio of the incident wave energy to the reflected wave energy is 1: (square of reflection coefficient mode), it is clear from the above that the higher the standing wave ratio is, the higher the reflected power is, and the lower the transmission efficiency is. The detection results of the rotation function and the electrical function are shown in the following table:
table 1 detection results of rotation function and electrical function of external antenna
As can be seen from the above table, the rotation function of the tube shaft in the external antenna is basically normal; the voltage standing wave ratio of the external antenna in the low frequency band is not more than 1.8, the voltage standing wave ratio of the high frequency band is not more than 3, and the electrical function of the external antenna is normal, so that the reliability of the external antenna is good, the function is stable, and the design requirement is completely met.
The foregoing is only illustrative of the present invention and is not to be construed as limiting the scope of the invention, and all equivalent structures or equivalent flow modifications which may be made by the teachings of the present invention and the accompanying drawings or which may be directly or indirectly employed in other related art are within the scope of the invention.
