However, when the screw is subjected to the limiting operation, the head of the screw is easily deformed after being subjected to multiple impacts of the antenna, so that the screw cannot be detached during the maintenance operation. Meanwhile, the screw is a vulnerable part when used as the pitching limiting mechanism, so that the use cost is increased due to the production and processing of the screw.
Referring to fig. 1, fig. 6 and fig. 7, in order to solve the above technical problems, in a first aspect, the present application provides a limiting member 10 used as a component of a pitching limiting mechanism 100, wherein the limiting member 10 is provided with a hole structure 11 along a thickness direction for being mounted on a mobile antenna 200, the limiting member 10 is provided with at least one notch 12 along the thickness direction at an outer edge portion, and the notch 12 is used to cooperatively receive an impact during a mechanical limiting operation.
The limiting part 10 can be made of metal or alloy and the like, and during production, the hole structure 11 and the cut 12 are punched on the limiting part 10 respectively, so that the structure is simple, the number of machining processes is small, machining is convenient, and the production cost and the use cost of the limiting part 10 are effectively reduced. During installation, a fixing member is inserted into the hole structure 11 and the locating member 10 is fixedly installed on the communication-in-motion antenna 200, wherein the fixing member may be a screw, a bolt, or the like, for example, a screw, a rod portion of the screw is inserted into the hole structure 11 and installed on the communication-in-motion antenna 200, and the screw is screwed so that the locating member 10 is fixed on the communication-in-motion antenna 200 by the screw.
The limiting piece 10 provided by the invention is installed by arranging the hole structure 11, the limiting piece 10 is installed on the communication-in-motion antenna 200 through the hole structure 11, at least one notch 12 is arranged on the limiting piece 10, and the notch 12 is used for realizing mechanical limiting when the antenna on the communication-in-motion antenna 200 is tilted. The invention uses the position limiter 10 to replace the screw as the structure for pitching position limiting, firstly, the position limiter 10 realizes mechanical position limiting through the notch 12 at the outer edge, the impact bearing capacity is higher, and the reliability is higher, meanwhile, when the position limiter 10 is installed through the hole structure 11, for example, the rod part of the screw is used for penetrating the hole structure 11 and connected with the communication-in-motion antenna 200, and the head part of the screw extrudes and fixes the position limiter 10, at the same time, the impact force borne by the position limiter 10 is transmitted to the rod part of the screw in surface contact with the position limiter 10, the rod part of the screw is dispersed and stressed evenly, the screw will not be damaged, namely, the position limiter 10 has strong reliability and will not be damaged to influence the maintenance work such as dismounting; secondly, the limiting part 10 only needs to adopt a punching process, and the limiting part 10 is provided with the hole structure 11 and the notch 12, so that compared with a screw, the limiting part has the advantages of low processing difficulty and simple structure, and further has low use cost and production cost.
Referring to fig. 1, fig. 6 and fig. 7, in an embodiment, the position-limiting element 10 has a plurality of notches 12 around a central axis of the hole structure 11 at an outer edge portion, diameters of the notches 12 are the same, and a distance between a central axis of each notch 12 and the central axis of the hole structure 11 is in a decreasing trend or an increasing trend. In the process of machining the stopper 10, machining errors, such as positional deviation of the hole structure 11 or positional deviation of the notch 12 at the time of punching, are likely to occur when the stopper 10 is punched. Meanwhile, during assembly, in the process of mounting the locating member 10 on the mobile communication antenna 200 by using the hole structure 11, the relative position of the locating member 10 and the mobile communication antenna 200 may also be shifted to generate an assembly error. Therefore, the limiting member 10 is punched a plurality of times to form a plurality of notches 12, so that each notch 12 is opened at the outer edge of the limiting member 10 around the central axis of the hole structure 11 of the limiting member 10; meanwhile, in order to make the cutting depths of the notches 12 different, when the die is used for punching the limiting member 10, a standard notch 12 is formed by punching, that is, when the distance between the die and the central axis of the hole structure 11 is a preset value, the die is moved to be far away from or close to the central axis of the hole structure 11 when the next notch 12 is punched, then the punching is performed, and the above actions are repeated for many times, so that a plurality of notches 12 are formed by punching. In this way, the depths of the notches 12 are different, when the limiting member 10 is installed on the mobile antenna 200 by using the hole structure 11, the limiting member 10 can be adjusted by rotation, the notches 12 with different depths are used to match with the limiting installation, and the most suitable notch 12 is found to complete the fixed installation, so that the error of the limiting member 10 during processing and the error generated during assembly are offset, and low-cost parts meet the requirement of high precision.
Referring to fig. 1 and 2, in an embodiment, the position-limiting member 10 is a disc-shaped structure, the standard depth of the notch 12 is J, and the distance between the central axis of the notch 12 and the central axis of the hole structure 11 is XnWherein n is the serial number of the notch 12, n is an integer greater than or equal to 1, and the distance X between the central axis of the notch 12 and the central axis of the hole structure 11nSatisfy the relationship
Where a is the diameter of the radial cross section of the stopper 10, C is the diameter of the cut 12, and K is the depth tolerance of each cut 12. The standard depth J refers to the depth of the notch 12 meeting the limit assembly under the ideal condition of no processing error and assembly error; the diameter of the notch 12 refers to the diameter of the circle where the arc surface of the notch 12 is located; the depth tolerance K of each slit 12 is determined by itself according to the actual situation, for example, when the number of the slits 12 is set to 6, the depth tolerance K of each slit 12 may be 0.1mm to 2mm, and when the number of the slits 12 is set to more, the depth tolerance of each slit 12 may be appropriately reduced, so that more slits 12 having the depth tolerance are obtained, and the assembly is facilitated. It will be appreciated that the diameter of each incision 12 is the same, and therefore C is constant. Taking the above relation as an example, when the number of the slits 12 is more than three, the distance between the central axis of the first slit 12 and the central axis of the hole structure 11
That is, the diameter a of the radial section of the limiting member 10 plus the diameter of the notch 12 minus the standard depth of the notch 12 is J, and the obtained value is half of the value, which is the distance between the central axis of the first notch 12 and the central axis of the hole structure 11. The distance between the central axis of the second cut-out 12 and the central axis of the hole structure 11
I.e. the distance between the centre axis of the second incision 12 and the centre axis of the hole structure 11 differs from the distance between the centre axis of the first incision 12 and the centre axis of the hole structure 11 by K. The distance between the central axis of the third cut 12 and the central axis of the hole structure 11
I.e. the distance between the centre axis of the third incision 12 and the centre axis of the hole structure 11 differs from the distance between the centre axis of the second incision 12 and the centre axis of the hole structure 11 by K. Similarly, the distance between the central axis of the nth notch 12 and the central axis of the hole structure 11
The difference K between the distance between the central axis of the nth notch 12 and the central axis of the hole structure 11 and the distance between the central axis of the (n-1) th notch 12 and the central axis of the hole structure 11. Through set up the incision 12 that a plurality of diameters are the same at the outer fringe portion of locating part 10, and the difference K in proper order between the distance between the axis of each incision 12 and the axis of pore structure 11 to utilize each incision 12 to carry out spacing assembly in proper order, find satisfy offset machining error and assembly error a incision 12 accomplish the installation can.
Referring to fig. 3, fig. 6 and fig. 7, in an embodiment, the position-limiting element 10 has a plurality of notches 12 around a central axis of the hole structure 11 at an outer edge portion, distances between central axes of the notches 12 and the central axis of the hole structure 11 are the same, and diameters of the notches 12 are in a decreasing trend or an increasing trend. In the process of machining the stopper 10, machining errors, such as positional deviation of the hole structure 11 or positional deviation of the notch 12 at the time of punching, are likely to occur when the stopper 10 is punched. Meanwhile, during assembly, in the process of mounting the locating member 10 on the mobile communication antenna 200 by using the hole structure 11, the relative position of the locating member 10 and the mobile communication antenna 200 may also be shifted to generate an assembly error. Therefore, the limiting member 10 is punched a plurality of times to form a plurality of notches 12, so that each notch 12 is opened at the outer edge of the limiting member 10 around the central axis of the hole structure 11 of the limiting member 10; meanwhile, in order to make the cutting depths of the respective notches 12 different, when the die is used to punch the limiting member 10, the die of different specifications is used for each punching, for example, the punching die is replaced every time a punching is completed, the die is replaced with a larger or smaller specification for the next punching, so that the distances between the central axes of the plurality of notches 12 formed in the outer edge portion of the limiting member 10 and the central axis of the hole structure 11 are the same, and the notches 12 of different diameters of the respective notches 12, for example, the diameters of the respective notches 12 are in a decreasing trend or an increasing trend, so that the depths of the respective notches 12 are different, when the limiting member 10 is mounted on the communication antenna 200 by using the hole structure 11, the limiting member 10 can be adjusted by rotation, the notches 12 of different depths are used to cooperate with limiting mounting, and the most suitable notch 12 is found to complete fixing, therefore, the errors generated during processing and assembly of the limiting piece 10 are offset, and low-cost parts meet the requirement of high precision.
Referring to fig. 4, 6 and 7, in an embodiment, the position-limiting element 10 has a plurality of notches 12 around a central axis of the hole structure 11 at an outer edge portion, a diameter of each notch 12 is gradually decreased or gradually increased, and a distance between a central axis of each notch 12 and a central axis of the hole structure 11 is gradually decreased or gradually increased. In the process of machining the stopper 10, machining errors, such as positional deviation of the hole structure 11 or positional deviation of the notch 12 at the time of punching, are likely to occur when the stopper 10 is punched. Meanwhile, during assembly, in the process of mounting the locating member 10 on the mobile communication antenna 200 by using the hole structure 11, the relative position of the locating member 10 and the mobile communication antenna 200 may also be shifted to generate an assembly error. Therefore, a plurality of notches 12 are punched in the through holes at the outer edge of the limiting part 10, the diameter of each notch 12 and the distance between the central axis of each notch 12 and the central axis of the hole structure 11 are set to be different, so that a plurality of notches 12 with different depths are obtained, when the limiting part 10 is installed on the mobile communication antenna 200 by using the hole structure 11, the limiting part 10 can be adjusted in a rotating mode, the notches 12 with different depths are used for matching with limiting installation, the most appropriate notch 12 is found to complete fixed installation, errors generated when the limiting part 10 is machined and assembled are offset, and low-cost parts meet high-precision requirements.

The limiting part 10 is set to be a rotational symmetric structure, and a plurality of notches 12 are uniformly distributed around the central axis of the hole structure 11 at the outer edge part of the limiting part 10, so that when the limiting part 10 is installed, the limiting part 10 can be installed on the communication-in-motion antenna 200 through the hole structure 11 by using a fixing part, the fixing part is pre-installed, at this time, the limiting part 10 can rotate around the fixing part, each notch 12 at the outer edge part of the limiting part 10 is respectively in limiting installation with a rotating part on the communication-in-motion antenna 200, so that a proper notch 12 (for offsetting a processing error and an assembly error) is found for limiting installation, and then the fixing part is completely installed, so that the limiting part 10 is fixedly installed on the communication-in-motion antenna 200. When trying to assemble each notch 12, because each notch 12 winds the axle wire equipartition in pore structure 11 and is in the outer fringe part of locating part 10, the turned angle of locating part 10 at every turn is definite value and the same to the effectual convenience that has improved the assembly of locating part 10. For example, when the number of the slits 12 is six, the rotation angle between the slits 12 is 60 °, and at this time, the fitting of the slits 12 can be adjusted only by rotating 60 degrees each time. The limiting member 10 may be of a disc structure, a rectangular disc structure, or other rotationally symmetric structures, and is specifically determined by itself according to actual conditions.
Referring to fig. 1 to 4, 6 and 7, in one embodiment, the hole structure 11 is a through hole for passing through the fixing member. The through hole is used as the hole structure 11, when the position-limiting member 10 is installed, a fixing member is inserted into the through hole and installed on the communication-in-motion antenna 200, and the fixing member presses the position-limiting member 10 to fix the position-limiting member 10. For example, the fixing member is a screw, a rod of the screw is inserted into the through hole and connected to the mobile communication antenna 200, and a head of the screw is screwed and pressed on the position-limiting member 10, so that the position-limiting member 10 is fixed. At this moment, the side wall of the through hole of the limiting member 10 contacts with the rod portion of the screw, when the limiting member 10 performs limiting operation, the impact of the mobile communication antenna 200 on the limiting member 10 is converted into the impact of the limiting member 10 on the rod portion of the screw, the limiting member 10 is in surface contact with the rod portion of the screw, the impact of the limiting member 10 on the rod portion of the screw is dispersed, and therefore the screw can bear larger impact and is not easily damaged, and the reliability of the limiting member 10 is high.
