Description

Technical Field

[0001] The utility model relates to the technical field of receivers, and in particular to a GNSS receiver. Background Art

[0002] At present, satellite navigation systems are widely used because they can provide all-weather, uninterrupted, real-time and high-precision three-dimensional positioning, three-dimensional speed measurement and precise time information. Common satellite navigation systems include Beidou Satellite Navigation System, GPS and GLONASS, etc. GNSS receivers are the basis of satellite navigation and positioning technology. They are mainly used to track, receive, process and output GNSS satellite data, and can be widely used in precision measurement, geological survey, timing, agriculture, transportation logistics and military fields.

[0003] When installing an existing GNSS receiver, the upper cover and the bottom body are often fixed by bolts, which is troublesome to install. In actual use, the electronic components inside the receiver may be damaged due to reasons such as service life. At this time, the staff needs to replace or repair them. When replacing or repairing, the bolts need to be slowly unscrewed one by one, which is cumbersome and inefficient. Therefore, we propose a GNSS receiver. Utility Model Content

[0026] Example 1

[0027] like Figure 1-3As shown, the utility model provides a technical solution: a GNSS receiver includes a receiver body 1, a cover plate 2 is installed on the top of the receiver body 1, a fixing column 201 is symmetrically arranged at the bottom of the cover plate 2 near the receiver body 1, a mounting groove 101 is opened on the inner side wall of the receiver body 1 corresponding to the fixing column 201, the fixing column 201 can be inserted into the inside of the mounting groove 101, an adjustment knob 102 is arranged on the outer side wall of the receiver body 1 corresponding to the mounting groove 101, and the adjustment knob 102 extends to the inside of the mounting groove 101 and is provided with an extension knob The retractable rod 103 and the telescopic rod 103 are provided with a limit block 104 at one end away from the adjusting knob 102. Turning the adjusting knob 102 can drive the telescopic rod 103 and the limit block 104 to rotate together. A spring 105 is sleeved on the periphery of the telescopic rod 103 and located between the inner side wall of the receiver body 1 and the limit block 104. The spring 105 can cooperate with the telescopic rod 103 to help the limit block 104 reset. A limit groove 202 is provided on the outer side wall of the fixed column 201 corresponding to the limit block 104, and the limit block 104 can be inserted into the limit groove 202.

[0028] Example 2

[0029] like Figure 1-3 As shown, a placement groove 106 is formed inside the receiver body 1 and between the installation grooves 101 , and electronic components required by the receiver can be directly installed through the placement groove 106 .

[0030] The fixing post 201 is matched with the installation slot 101 . By matching the fixing post 201 with the installation slot 101 , a worker can easily insert the fixing post 201 into the installation slot 101 when installing the receiver.

[0031] An anti-slip ring 107 is sleeved on the outer wall of the adjustment knob 102, and the anti-slip ring 107 is made of rubber material. A groove is opened on the inner wall of the receiver body 1 corresponding to the adjustment knob 102. The anti-slip ring 107 made of rubber material makes it easier and more convenient for the staff to turn the adjustment knob 102.

[0032] The limit block 104 is adapted to the limit groove 202. The limit block 104 is triangular in design. The limit block 104 with a triangular design and adapted to the limit groove 202 allows the fixing column 201 to be fixed very conveniently when the limit block 104 is inserted into the limit groove 202. The fixing column 201 can also be conveniently taken out by rotating the limit block 104.

[0033] A control panel 3 is provided on the outer side wall of the receiver body 1 .

[0034] The working process of the utility model is as follows: when using a GNSS receiver, first, the staff can directly place the cover plate 2 directly above the receiver body 1, so that the fixing column 201 can be inserted into the installation groove 101, and when the fixing column 201 descends in the installation groove 101, it will exert a compressive effect on the limit block 104. When the limit block 104 is pressed, it can move toward the adjustment knob 102 through the telescopic rod 103 and the spring 105, so that the fixing column 201 can continue to descend until the limit groove 202 and the limit block 104 are at the same height. At this time, the compressive effect of the fixing column 201 on the limit block 104 will disappear. When the positioning knob 102 is turned, the spring 105 is reset, so that the limit block 104 can be directly inserted into the limit groove 202 to complete the installation of the receiver. If the receiver needs to be disassembled, the adjustment knob 102 can be turned to change the direction of the limit block 104, so that the entire cover plate 2 and the fixing column 201 can be directly pulled out to complete the disassembly of the receiver and directly replace or repair the electronic components inside the receiver. Compared with the existing GNSS receiver, it is more convenient to install and disassemble, thereby improving the convenience and practicality of the GNSS receiver during installation and disassembly.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
