Description

Technical Field

[0001] The present invention relates to the technical field of monitoring device connection terminals, in particular to a monitoring device mobile terminal. Background Art

[0002] A typical television monitoring system is mainly composed of two parts: front-end equipment and back-end equipment. The front-end equipment usually consists of components such as cameras, manual or electric lenses, pan / tilt heads, protective covers, monitors, alarm detectors and multi-function decoders. They each have their own functions and establish corresponding connections with various devices of the central control system through wired, wireless or optical fiber transmission media, including mobile terminals. Mobile terminals broadly include mobile phones, notebooks, tablets, POS machines and even car computers, but in most cases refer to mobile phones or smart phones and tablets with multiple application functions. Mobile terminals have different appearances, and most mobile terminals have a handle at the bottom for staff to hold.

[0003] A mobile terminal that looks like a mobile phone consists of a shell, buttons, a grip and various electronic components inside. When a staff member carries the mobile terminal with him / her when traveling, he / she can choose to remove the grip from the bottom of the shell. Although the mobile terminal can be put into a pocket after the grip is removed, the removed grip will still occupy a certain amount of space on the staff member, which is less convenient. Summary of the invention

[0004] In view of the problems in the prior art, the present invention provides a monitoring device mobile terminal.

[0005] The technical solution adopted by the present invention to solve its technical problem is: a monitoring device mobile terminal, including a shell, a mounting shell, a screw rod and an active rack, the top of the shell is rotatably connected to a symmetrically arranged first round rod, the bottom of the shell is fixedly connected to a symmetrically arranged second round rod, the two first round rods are fixedly connected to a transmission gear, the two second round rods are fixedly connected to a fixed gear, the screw rod is threadedly connected to a moving seat, both sides of the moving seat are provided with accommodating grooves, the insides of the two accommodating grooves are fixedly connected to a first connecting rod, the two first connecting rods are rotatably connected to a linkage rod, the opposite sides of the two active racks are fixedly connected to a bracket, and the two brackets are fixedly connected to a second connecting rod;

[0006] A plurality of the mounting shells are slidably connected with moving blocks, two of the moving blocks at the bottom are provided with transverse grooves, a plurality of tooth blocks are fixedly connected inside the two transverse grooves, one side of the two moving blocks and one side of the other two moving blocks are fixedly connected with a handle, the two mounting shells at the bottom are rotatably connected with a rotating rod, the two rotating rods are fixedly connected with a driven gear, and the two rotating rods are fixedly connected with a linkage gear;

[0007] The two active racks are meshed and connected with the transmission gear, the two connecting rods are rotationally connected with the second connecting rod, the two driven gears are meshed and connected with the fixed gear, and the two connecting gears are meshed and connected with the gear block.

[0008] Specifically, a protective shell is fixedly connected to the top of the shell body, a symmetrically arranged guide rod is fixedly connected inside the protective shell, a symmetrically arranged limit rod is fixedly connected inside the protective shell, the two guide rods are both slidably connected to the active rack, and the two limit rods are both slidably connected to the movable seat.

[0009] Specifically, there are four mounting shells in total, the two mounting shells at the top are respectively fixedly connected to the top of the first round rod, and the two mounting shells at the bottom are respectively rotatably connected to the bottom of the second round rod.

[0010] Specifically, the top ends of the two rotating rods are rotatably passed through the top wall of the mounting shell to be fixedly connected to the driven gear, and the bottom ends of the two rotating rods are rotatably passed through the top wall of the mounting shell to be fixedly connected to the linkage gear.

[0013] Specifically, the two handles are respectively located on the sides of the shell, and the two handles are the same in shape and size.

[0014] Beneficial effects of the present invention:

[0015] The present invention connects the handle and the shell as a whole, and the two handles are respectively located on the sides of the shell, which can prevent the staff from accidentally touching the functional buttons on both sides of the shell. When the mobile terminal needs to be used to observe the monitoring screen, the two handles can be rotated toward the back of the shell through the linkage of various mechanisms. The rotation of the two handles can cause the various mechanisms to be linked, so that the handles move and extend during the rotation process. When the two handles rotate to the back of the shell, the handles are also fully extended. At this time, the handles and the back wall of the shell have a certain accommodating space, thereby providing sufficient gripping space for the staff. The staff can hold the two handles at the same time to achieve the purpose of gripping the entire mobile terminal. The present invention eliminates the step of removing the handles, integrates the handles with the shell, saves the space occupied by the entire mobile terminal on the staff, is convenient for the staff to carry when traveling, and is highly convenient.

[0027] A plurality of the mounting shells 2 are slidably connected with moving blocks 15, two of the moving blocks 15 at the bottom are provided with transverse grooves 16, a plurality of tooth blocks 17 are fixedly connected inside the two transverse grooves 16, one side of the two moving blocks 15 and one side of the other two moving blocks 15 are fixedly connected with a handle 18, two of the mounting shells 2 at the bottom are rotatably connected with a rotating rod 19, two of the rotating rods 19 are fixedly connected with a driven gear 20, and two of the rotating rods 19 are fixedly connected with a linkage gear 21;

[0028] The two active racks 4 are meshed and connected with the transmission gear 7 , the two connecting rods 12 are rotationally connected with the second connecting rod 14 , the two driven gears 20 are meshed and connected with the fixed gear 8 , and the two connecting gears 21 are meshed and connected with the gear block 17 .

[0029] Specifically, a protective shell 22 is fixedly connected to the top of the shell 1, and a symmetrically arranged guide rod 23 is fixedly connected inside the protective shell 22. A symmetrically arranged limit rod 24 is fixedly connected inside the protective shell 22. The two guide rods 23 are both slidably connected to the active rack 4, and the two limit rods 24 are both slidably connected to the movable seat 9. The guide rod 23 is convenient for guiding the movement of the active rack 4, and the limit rod 24 is convenient for guiding the movement of the movable seat 9.

[0030] Specifically, there are four mounting shells 2 in total, the two mounting shells 2 at the top are respectively fixedly connected to the top end of the first round rod 5, and the two mounting shells 2 at the bottom are respectively rotatably connected to the bottom end of the second round rod 6.

The movement of the two active racks 4 in the direction away from each other will drive the transmission gear 7 to rotate. The rotation of the transmission gear 7 will drive the first round rod 5 to rotate. The two first round rods 5 will drive the top mounting shell 2 to rotate toward the back wall of the shell 1. The two mounting shells 2 at the top will respectively drive the mounting shell 2 at the bottom to rotate through the moving block 15 and the grip 18. When the two mounting shells 2 at the bottom rotate, the two handles 18 are on the way to rotating toward the back wall of the shell body 1, and the two mounting shells 2 at the bottom end will rotate with the second round rod 6 as the center, while the positions of the second round rod 6 and the fixed gear 8 remain unchanged. When the two mounting shells 2 at the bottom end rotate, they will drive the rotating rod 19, the driven gear 20 and the connecting gear 21 to rotate together. The driven gear 20 will rotate with the rotating rod 19 as the center because it is connected to the fixed gear 8 during the following rotation.
