[0022] Referring to Figure 1 , the present utility model provides a push-pull connection structure, including a bottom case 1, an upper case 2, and a middle case 3.
[0023] Wherein, as Figure 2 , an indicator light groove 30, a SIM card holder groove 31, a serial port groove 32, an antenna groove 33, and a switch position 34 are provided on the middle case 3. This part is similar to the existing one and will not be elaborated in this embodiment. It is used for observing the indicator light, installing the SIM card, passing through the serial port, passing through the antenna, and passing through the switch.
[0024] The middle case 3 is detachably connected to the inside of the bottom case 1. First studs 10 are provided at the four corners inside the bottom case 1, and the middle case 3 is locked to the first studs 10 by screws.
[0025] Secondly, bottom case buckles 11 are further provided on both sides inside the bottom case 1, and second clamping positions 35 corresponding to the bottom case buckles 11 are provided on the outer side of the middle case 3. The bottom case buckles 11 and the second clamping positions 35 are in clamping cooperation. During installation, first, the second clamping position 35 on the middle case 3 is snapped into the bottom case buckle 11, and then it is locked to the first stud 10 by screws.
[0026] In particular, the upper case 2 and the middle case 3 can slide and achieve snap-fitting fixation or detachment when sliding to a certain stroke.
[0027] Specifically, a sliding groove 36 is formed in the middle shell 3, and a sliding buckle 20 corresponding to the sliding groove 36 is provided on the upper shell 2. The sliding buckle 20 is inserted into the sliding groove 36 correspondingly and is pushed to a certain stroke and then clamped and fixed. Further, a concave position 21 is formed on the bottom surface of the upper shell 2, and the sliding buckle 20 is formed on the concave position 21. And, more preferably, the cross section of the sliding buckle 20 is L-shaped, and a first clamping position 200 is further formed on the inner side of the bottom of the sliding buckle 20. A clamping point 37 is formed on the outer side of the bottom of the sliding groove 36. When the sliding buckle 20 is inserted into the sliding groove 36 and the upper shell 2 is pushed until the clamping point 37 is engaged with the first clamping position 200, the upper shell 2 is clamped and fixed to the middle shell 3, so as to realize the sliding locking and fixing. When the upper shell 2 is pushed in the reverse direction, the upper shell 2 can be separated from the middle shell 3. Through this sliding locking structure, a more reliable connection can be achieved, and it has stronger anti-drop performance, does not occupy too much space, is beneficial to miniaturization, and can be recycled and is convenient to operate.
[0028] Such as Figure 1 , another solution provides a satellite positioning terminal, including the push-pull connection structure of the above solution. The satellite positioning terminal further includes a PCBA module 4 for receiving satellite positioning data and sending it to the platform server, and a board-mounted wire 5 for supplying power to the PCBA module 4.
[0029] Second studs 12 are provided at the diagonal positions inside the bottom shell 1. The PCBA module 4 is locked and fixed to the second studs 12 by screws. The middle shell 3 is arranged on the PCBA module 4. One end of the board-mounted wire 5 is connected to the PCBA module 4 by soldering, and the board-mounted wire 5 extends out from one end of the bottom shell 1. The middle shell 3 plays a role in covering the key parts of the PCBA to prevent the components from being damaged by static electricity of the hand during disassembly and assembly. The upper shell 2 covers the exposed PCBA components to achieve an aesthetic effect. After receiving Beidou or GPS satellite data through the PCBA module 4, it is sent to the platform server, so that the user can know the position of the satellite positioning terminal in real time.
