Detailed Description
The construction and use of the invention will now be further described with reference to the accompanying drawings. As shown in fig. 1 and 2, a handle 7 is arranged in a base 6 of the plane lock, and one end of the handle is connected with the steel bolt 1 through a rotating shaft and a screw. The concrete structure is as follows: the rotating shaft comprises a rotating shaft rod 4 and a rotating shaft head 5, one end of the rotating shaft head is connected with one end of the handle, the other end of the rotating shaft head is sleeved in a rotating shaft extending hole fixed on the base and is connected with one end of the rotating shaft rod through external threads, and a sealing ring is arranged at the connecting part of the rotating shaft head in the base and the base; the other end of the rotating shaft rod is connected with the steel bolt through a screw and a flat key surface of the end, namely, an internal thread is arranged in the screw hole of the rotating shaft rod at the end, and the rotating shaft rod is connected with the screw through the internal thread at the end. The junction of above-mentioned pivot pole and screw is equipped with fixed block 3, and the pivot external diameter that pivot pole and pivot head are constituteed is equipped with position sleeve 2, and the fixed block is located between the screw end of one end and pivot pole in the position sleeve, and the fixed block embolias the steel peg after stretching out the position sleeve, is equipped with the gasket between position sleeve and the fixed block, and the other end and the base medial surface of position sleeve are connected. A punching elastic sheet is arranged above the fixing block on one side of the positioning sleeve, the fixing block is fixed in the positioning sleeve through the punching elastic sheet, and a through hole is formed in the punching elastic sheet of the positioning sleeve. Meanwhile, a torsional spring is arranged at the joint of the handle and the rotating shaft, a lock cylinder 10 is arranged in the other end of the handle, and the end of the handle is fixedly connected with the base through the lock cylinder; the lock core department of handle is equipped with shield 9, and the one end of shield is passed through screw 8 and is connected with the handle.
When the plane lock is used, the dustproof cover is opened, the lock cylinder is inserted into the key, the lock cylinder is opened, the handle in the base can be ejected out, the handle is rotated, and the handle can drive the steel bolt to rotate through the rotating shaft, so that the plane lock is locked and unlocked. When the pivot is assembled, the pivot head of pivot embolias the pivot of base and stretches out the hole, rotates the overhead pivot pole of pivot, can adjust the length between pivot pole and the pivot head to adjust the length of pivot. After the length of the rotating shaft is adjusted, the fixing block, the elastic gasket, the positioning sleeve and the steel bolt are sequentially sleeved into the rotating shaft rod, the fixing block, the elastic gasket, the positioning sleeve and the steel bolt can be fixed on the rotating shaft rod through screws, and the rotating shaft side of the plane lock can be assembled.
According to the structural characteristics and the use characteristics, the height of the positioning sleeve can be further finely adjusted through the gasket between the positioning sleeve and the base, and then the length of the rotating shaft is adjusted. Meanwhile, according to the prior art characteristics, the rotating shaft rod and the rotating shaft head of the rotating shaft can be connected into a whole, and the positioning sleeve and the fixing block can also be arranged on the rotating shaft in the same way; or the positioning sleeve and the rear cover are integrally formed, and the same use purpose and technical effect of the positioning sleeve can be realized.
The invention relates to the industries of telecommunication, electric power, automatic control manufacturing and the like, in particular to a door lock of a communication cabinet, a network cabinet, an electric power cabinet and a control cabinet in the industries. The invention cancels the structure that the steel bolt is directly fixed on the rotating shaft by the screw and the adjusting gasket in the traditional structure of the similar product, and divides the existing rotating shaft into two-section structure, and a positioning sleeve of the rotating shaft and the fixing block are added, thereby realizing the purpose of avoiding the problems of the traditional structure. The advantages of the invention are as follows: 1. because the rotating shaft is divided into a two-section structure, and a positioning sleeve of the rotating shaft and the fixing block are added, the requirement on the matching tolerance of the rotating shaft and the base hole is reduced. 2. Because the structure of the invention cancels an integrated rotating shaft, the rotating shaft is divided into two sections, namely a rotating shaft rod and a rotating shaft head; a certain gap is formed between the connecting part of the structure transfer shaft lever and the rotating shaft head; the defect that the handle can deviate when the handle is driven by the deviation of the rotating shaft pressed by the steel bolt under stress in the door closing process is avoided. 3. Because the structure of the invention is additionally provided with the positioning sleeve and the fixing block, the deviation of the transfer shaft rod in the process of the steel bolt under stress in the door closing process is ensured through the assembly and the matching of the fixing block and the positioning sleeve. In conclusion, the structure of the invention solves the problem that the handle cannot be normally bounced or rotated and blocked when the lock is unlocked.
