Abstract
The utility model belongs to the technical field of GPS equipment application, mainly relating to a flexible connecting sealing ring of an RTK mobile station. The sealing ring (1) made of light rubber is of a bell-shaped hollow structure, the inner diameter of the upper end thereof is coincided with the outer diameter of the root part of an antenna so as to be sheathed at the root part of the antenna (2), and the lower end thereof is of a sucking disc structure which is absorbed on the surface of an upper hard shell of a machine head (3); and the section from the upper end to the lower end of the sealing ring (1) is a bell-mouthed transition section with the gradually-increased diameter. The sealing ring is sheathed between the external antenna and the surface of the upper hard shell of the machine head, so as to prevent water from entering interior of the machine body from a bayonet part; and a rubber structure reduces the influence of swinging of the antenna on the bayonet of the antenna.
Description
Technical field
The utility model belongs to GPS equipment applied technical field, relates generally to a kind of RTK mobile radio station sealing joint circle.
Background technology
RTK is a kind of measurement type GPS global positioning system, and in recent years, the RTK technology constantly develops, and its field of measuring technique that is used for by people is more and more widely come, and the antenna of RTK equipment is an external antenna, is used for receiving base station signal and satellite-signal.The bayonet socket that external antenna is connected with head is rigid joint, external antenna inevitably will rock in the process of measuring, time one, the long bayonet socket that makes easily was loosening, cause antenna bottom and main frame loose contact, influence the reception and the transmission of signal, the loosening of bayonet socket position easily makes extraneous moisture enter head inside from bayonet socket, and the mainboard of head inside and chip are destroyed, and slowed down the useful life of main frame greatly.Also accelerate simultaneously the replacing of part, strengthened the input cost of equipment virtually.
Summary of the invention
The purpose of this utility model is to propose a kind of RTK mobile radio station antennal interface sealing ring, it can be solved in the measuring process cause RTK external antenna interface and head loose contact, signal to receive problem bad and that bayonet socket is loosening because antenna rocks.
The utility model takes following technical proposals to finish its invention task:
A kind of RTK mobile radio station antennal interface sealing ring, the described sealing ring of being made by lightweight rubber is horn-like hollow structure, its upper-end inner diameter and antenna root external diameter kiss adapted are to be enclosed within the root of antenna, and the lower end is that sucker structure is adsorbed on the surface of head top duricrust; Described sealing ring upper end is the horn mouth changeover portion in flaring footpath to the lower end.
A kind of RTK mobile radio station antennal interface sealing ring that the utility model proposes, its sealing ring is put between the surface of external antenna and head top duricrust, prevented that moisture from entering internal body from the bayonet socket position, the colloid structure has been slowed down antenna and has been rocked influence to the antenna bayonet socket.
Description of drawings
Fig. 1 is a user mode schematic diagram of the present utility model.
Among the figure, 1, sealing ring, 2, antenna, 3, head, 4, antennal interface.
Embodiment
The example that provides in conjunction with the accompanying drawings is illustrated the utility model:
As shown in Figure 1, a kind of RTK mobile radio station antennal interface sealing ring, described sealing ring 1 is horn-like hollow structure, adopts lightweight rubber to make, its upper-end inner diameter and antenna 2 root external diameters kiss adapted are to be enclosed within the root of antenna, and the lower end is that sucker structure is adsorbed on the surface of head 3 top duricrusts; Described sealing ring 1 upper end is the horn mouth changeover portion in flaring footpath to the lower end.
Sealing ring 1 wealthy mouth down is inserted in by antenna 2 tops and until the root of antenna, again terminal sucker under the sealing ring is ripped to flatten and be adsorbed in head top duricrust upper surface, can weaken and rock and vibrate stress influence antenna and bayonet socket, and prevent that effectively extraneous moisture from entering, prolonged the useful life of mobile radio station antenna and head.
Claims (1)
1. RTK mobile radio station antennal interface sealing ring, it is characterized in that: the described sealing ring of being made by lightweight rubber (1) is horn-like hollow structure, its upper-end inner diameter and antenna root external diameter kiss adapted are to be enclosed within the root of antenna (2), and the lower end is that sucker structure is adsorbed on the surface of head (3) top duricrust; Described sealing ring (1) upper end is the horn mouth changeover portion in flaring footpath to the lower end.
