In conjunction with the accompanying drawings, some embodiments of the present invention are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

Example 1

1 to 4 , the present embodiment provides a rear shell 1 structure of a positioning instrument, which includes a rear shell 1, wherein the rear shell 1 includes a rectangular main board 101 and a rectangular frame 102, wherein the rectangular frame 102 is correspondingly arranged on four sides of the rectangular main board 101, and the rectangular main board 101 and the rectangular frame 102 are spliced to form a rectangular trough structure of an integrated structure (i.e., the overall shape of the rear shell 1 is a rectangular trough structure).

The rectangular mainboard 101 is provided with a plurality of embedded nuts 104, and the embedded nuts 104 are made of a harder material, such as stone, metal, etc. By pre-embedding a plurality of embedded nuts 104 in advance during the injection molding process of the rear shell 1, the embedded nuts 104 and the rear shell 1 shell form a whole, and the embedded nuts 104 are made of a harder material, and the embedded nuts 104 are preferably made of copper. Compared with the method of directly opening a hole on the plastic rear shell 1 in the prior art, the embedded nuts 104 are more secure when the fixing screws 8 are installed through their own structure, and the embedded nuts 104 themselves have internal threads, which can be firmly connected to other external objects and fix the locator itself, thereby solving the problem of loose fixing points and the problem of easy failure of the secondary installation fixing points after maintenance and disassembly, and reducing the problem of increased maintenance costs of replacing the entire housing due to loose installation points after maintenance.

Preferably, four embedded nuts 104 are respectively arranged at the four corners of the rectangular main board 101 on the rear housing 1 .

The outer wall of the embedded nut 104 is provided with a knurled structure 106 of an integral structure, so that after injection molding, the knurled structure 106 can enhance the connection firmness between the embedded nut 104 and the shell of the rear shell 1. When the rear shell 1 is fixedly connected to other external objects, the external object needs to be threadedly connected with the internal thread of the embedded nut 104 through the screw 8. During the threaded connection, the screw 8 rotates along the texture of the internal thread. At this time, if the outer wall of the embedded nut 104 is not provided with a knurled texture and its outer surface is smooth, it is very likely that the force generated by the rotation will cause relative looseness between the embedded nut 104 and the shell of the rear shell 1, which will cause the embedded nut 104 to be loose and not firm. In the present application, after the outer wall of the embedded nut 104 is provided with an integrated knurled structure 106, due to the uneven texture structure of the knurled structure 106, after the rear shell 1 is integrally injection molded, the convex and concave texture of the knurled structure 106 of the embedded nut 104 is tightly clamped to the shell of the rear shell 1, even if a rotational force is generated when the screw 8 is installed, the embedded nut 104 and the shell of the rear shell 1 will not become relatively loose, thereby ensuring a firm connection.

The entire outer wall of the embedded nut 104 is provided with a knurled structure 106; or, the upper and lower parts of the outer wall of the embedded nut 104 are respectively provided with segmented knurled structures 106 (i.e., upper and lower two-stage knurled structures 106), and an annular groove 107 is formed between the knurled structures 106 at the upper and lower parts; or, the upper and middle parts of the outer wall of the embedded nut 104 are respectively provided with segmented knurled structures 106 (i.e., middle and upper two-stage knurled structures 106), and an annular groove 107 is formed between the knurled structures 106 at the upper and middle parts. ; or, the middle and lower parts of the outer wall of the embedded nut 104 are respectively provided with segmented knurled structures 106 (i.e., middle and lower two-stage knurled structures 106), and annular grooves 107 are respectively formed between the knurled structures 106 in the middle and lower parts; or, the upper, middle and lower parts of the outer wall of the embedded nut 104 are respectively provided with segmented knurled structures 106 (i.e., three-stage knurled structures 106), and annular grooves 107 are respectively formed between the knurled structures 106 in the upper and middle parts, and between the knurled structures 106 in the middle and lower parts.

In this embodiment, preferably, the knurled structure 106 on the outer wall of the embedded nut 104 is designed as the above-mentioned three-section knurled structure 106, as shown in FIG. 3 and FIG. 4 .

In order to facilitate the clearness of the specific positions of the four embedded nuts 104 on the back shell 1, an XOY plane rectangular coordinate system is established on the rectangular main board 101. Specifically, the length of the rectangular main board 101 is 109.5 mm and the width is 82 mm. The center point of the rectangular main board 101 is taken as the coordinate origin, and the length direction of the rectangular main board 101 is taken as the X-axis and the width direction is taken as the Y-axis to establish a plane rectangular coordinate system, wherein the numerical units on the X-axis and the Y-axis are both millimeters. The four embedded nuts 104 are respectively located in the first quadrant, the second quadrant, the third quadrant and the fourth quadrant. The embedded nuts 104 located in the first quadrant, the second quadrant, the third quadrant and the fourth quadrant are respectively recorded as P1, P2, P3, and P4, and the coordinates of the four embedded nuts 104 are P1 (47.75, 34), P2 (47.75, -34), P3 (-47.75, -34) and P4 (-47.75, 34). P1 and P2, as well as P3 and P4 are all symmetrical about the X-axis, and P1 and P4, as well as P3 and P2 are all symmetrical about the Y-axis.

The rectangular main board 101 also has a plurality of countersunk holes 105, and the countersunk holes 105 are used to install connecting bolts 9 that can be connected to the front shell 2; and the coordinates of the three countersunk holes 105 are (34.85, -3.49), (-30.94, -32.77) and (-16.90, 33.25) respectively.

Preferably, the inner diameter of the internal thread of the embedded nut 104 is set to 3 mm, and the depth of the embedded nut 104 is designed to be 6 mm. The inner diameter of the annular groove 107 is 6 mm, and the maximum outer diameter of the knurled structure 106 is 7 mm.

The rear housing 1 is also provided with a heat dissipation hole 103 for mounting the heat sink 5 , and the center of the rectangular mainboard 101 is located inside the heat dissipation hole 103 .

The rectangular frame 102 includes a first side panel, a second side panel, a third side panel and a fourth side panel which are connected end to end in sequence. The first side panel is provided with a slot for a WIFI antenna 7, the second side panel is provided with a circuit board slot for connecting a circuit board, and the fourth side panel is provided with a slot for a GPS antenna 6.

Example 2

1-8 , this embodiment provides a high-precision locator, which includes the locator rear shell 1 structure in Embodiment 1, and also includes a front shell 2, a first circuit board 3, a second circuit board 4, a heat sink 5, a GPS antenna 6, a WIFI antenna 7, a screw 8 matching the embedded nut 104, and a connecting bolt 9 matching the countersunk hole 105.

Connecting bolts 9 are installed in the three countersunk holes 105 to fix the front shell 2 and the rear shell 1 to form the shell of the locator. The first circuit board 3 and the second circuit board 4 are installed in the shell, and the heat sink 5 is installed in the heat dissipation hole 103 of the rear shell 1, and the heat sink 5 is fixed by bolts. The heat sink 5 is against the circuit board (the first circuit board 3 or the second circuit board 4) to dissipate heat from the circuit board in the shell. The WIFI antenna 7 is installed at the WIFI antenna 7 slot of the rear shell 1, and the GPS antenna 6 is installed at the GPS antenna 6 slot of the rear shell 1.

Preferably, the screw 8 matching the embedded nut 104 and the connecting bolt 9 matching the countersunk hole 105 are both self-tapping screws of the same type.

The beneficial effects of the technical solution of the utility model are:

The rear shell 1 of the positioning instrument of the present application is embedded with several embedded nuts 104 in advance during the injection molding process, so that the embedded nuts 104 and the rear shell 1 shell form a whole, and the embedded nuts 104 can be made of a harder material (such as copper), and the structure of the embedded nuts 104 itself makes it more secure when the fixing screws 8 are installed, and the embedded nuts 104 themselves have internal threads, which can be firmly connected to other external objects and fix the positioning instrument itself, thereby solving the problem of loose fixing points and the problem of easy failure of the secondary installation fixing points after maintenance and disassembly, and reducing the problem of increased maintenance costs of replacing the entire casing due to loose installation points after maintenance. The installation is secure, removable, and easy to repair and install twice, which reduces the cost of possible scrapping after disassembly and maintenance. It can ensure that the housing and its matching structural parts are more secure after being fixed, and does not affect the scrap rate of continued use after disassembly.

First of all, the embedded part (i.e., the embedded nut 104) is a copper stud with internal threads, and the locking force will not be lost due to the number of times of disassembly during repeated disassembly and assembly. Traditionally, the plastic part is fixed with self-tapping screws through the holes reserved in the plastic part itself. After the second disassembly and assembly, the fixing hole will expand due to the material of the plastic part itself. When it is installed again, the locking force of the screw 8 will be attenuated to varying degrees, causing it to fall off and fail during movement. The embedded nut 104 made of copper embedded in the fixed position of the plastic part can well avoid this problem.
