Abstract
After the upper cover and the lower cover are locked by the screw, the screw is not shaken or loosened by arranging the lock rod which passes through the screw in a transverse mode, so that the upper cover and the lower cover can be locked more stably; the screw is provided with the lug which is used as a force application point for the rotation of the screw, so that the screw can be locked and loosened more conveniently; the second spring is arranged, so that the threads of the screw can be tightly attached to the threads between the lock hole and the lock groove, and the fastening performance of the screw is further enhanced; the bottom of the screw is provided with a protrusion matched with the stop block in the lock groove, when the screw is screwed down and the through hole corresponds to the lock rod, the protrusion is just abutted to the stop block, and therefore the limiting effect is achieved.
Description
Technical Field
The utility model belongs to RTU equipment especially relates to an anti-looseness intelligence RTU.
Background
The RTU is used as a remote telemetry terminal, is widely applied to the field of Internet of things, and is particularly used for data monitoring and data transmission in industries such as intelligent agriculture, smart cities, intelligent environmental protection and the like. Therefore, many RTUs need place or hang in the open air, and sometimes the outdoor environment is comparatively abominable, leads to the not hard up or the coming off of the screw of RTU shell easily to make RTU internal circuit receive the harm, influence data transmission.
SUMMERY OF THE UTILITY MODEL
The utility model provides a locking intelligent RTU that moves can let RTU's structure more firm.
The utility model discloses a following mode realizes:
an anti-loosening intelligent RTU comprises a shell, wherein the shell comprises an upper cover and a lower cover, the upper cover and the lower cover are detachably connected through an anti-loosening mechanism, and the anti-loosening mechanism comprises a screw, a lock hole and a locking block; the lock hole is arranged on the edge of the upper cover; the locking block is arranged on the edge of the lower cover and corresponds to the lock hole; the locking block is provided with a locking groove matched with the locking hole; the screw is in threaded fit with the lock hole and the lock groove to lock the upper cover and the lower cover, and the locking block is provided with a chute; a sliding lock rod is arranged in the sliding groove; the lower end of the screw is provided with a through hole matched with the lock rod; the end part of the lock rod is provided with a shifting block; the shifting block is connected with the inner wall of the locking block through a first spring.
Furthermore, two symmetrical lugs are arranged at the top of the screw.
Furthermore, a second spring is sleeved between the lower end of the top of the screw and the lock hole.
The utility model has the advantages that: after the upper cover and the lower cover are locked by the screw, the screw is not shaken or loosened by arranging the lock rod which passes through the screw in a transverse mode, so that the upper cover and the lower cover can be locked more stably; the screw is provided with the lug which is used as a force application point for the rotation of the screw, so that the screw can be locked and loosened more conveniently; the second spring is arranged, so that the threads of the screw can be tightly attached to the threads between the lock hole and the lock groove, and the fastening performance of the screw is further enhanced; the bottom of the screw is provided with a protrusion matched with the stop block in the lock groove, when the screw is screwed down and the through hole corresponds to the lock rod, the protrusion is just abutted to the stop block, and therefore the limiting effect is achieved.

Detailed Description
An anti-loosening intelligent RTU comprises a shell, wherein the shell comprises an upper cover 1 and a lower cover 2, the upper cover 1 and the lower cover 2 are detachably connected through an anti-loosening mechanism, and the anti-loosening mechanism comprises a screw 3, a lock hole 4 and a locking block 5; the lock hole 4 is arranged at the edge of the upper cover 1; the locking block 5 is arranged on the edge of the lower cover and corresponds to the lock hole 4; the locking block 5 is provided with a locking groove 6 matched with the locking hole 4; the screw 3 is in threaded fit with the lock hole 4 and the lock groove 6 to lock and fix the upper cover 1 and the lower cover 2, and the locking block 5 is provided with a sliding groove 7; a sliding lock rod 8 is arranged in the sliding groove 7; the lower end of the screw 3 is provided with a through hole 9 matched with the lock rod 8; the end part of the lock rod 8 is provided with a shifting block 10; the shifting block 10 is connected with the inner wall of the locking block 5 through a spring 11.
When the upper cover and the lower cover are locked by the screw, the shifting block is firstly shifted, the locking block is provided with a guide rail hole 14 which is matched with the shifting block, and the shifting block can move in the guide rail hole; the spring is compressed, the lock rod moves backwards, and when the screw is screwed to a proper position, the through hole is matched with the lock rod; at the moment, the shifting block is loosened, the lock rod extends into the through hole under the action of the spring and passes through the screw in a transverse mode, and the main screw is clamped, so that the screw cannot shake or loosen, and the upper cover and the lower cover can be locked more stably;
furthermore, two symmetrical lugs 12 are arranged at the top of the screw 3.
The lug is used as a force application point for the rotation of the screw, so that the screw can be locked and loosened more conveniently.
Further, a second spring 13 is sleeved between the lower end of the top of the screw 3 and the lock hole 4.
The second spring is arranged, so that the screw thread of the screw can be tightly attached to the screw thread between the lock hole and the lock groove, and the fastening performance of the screw is further enhanced.
