The lock catch structure for the rear frame door of the switch cabinet is characterized in that the first bolt is located on the upper base and the lower base outside the fixing hole.
The lock catch structure for the rear frame door of the switch cabinet is characterized in that a lock hole is formed in the lower base, a limiting step is formed in one side of the lock hole, the lower end of the first bolt extends to the lower portion of the limiting step, and the second bolt penetrates through the lock hole to be connected with the lock body.
The lock catch structure for the rear frame door of the switch cabinet is characterized in that a baffle plate positioned above the upper base is arranged at the top of the first bolt, and a strip hole is formed in the middle of the first bolt.
The lock catch structure for the rear frame door of the switch cabinet is characterized in that a clamping block is arranged on one side of the second bolt, the clamping block is arranged in the long-strip hole, and the bottom of the clamping block is mutually attached to the bottom of the long-strip hole.
The lock catch structure for the rear frame door of the switch cabinet is characterized in that the second bolt is L-shaped, and a folded plate positioned above the lower base is arranged at the top of the second bolt.
Compared with the prior art, the upper base and the lower base are respectively connected with the two rear frame doors of the switch cabinet, the upper base and the lower base are mutually connected through the first bolt, the clamping block of the second bolt is buckled into the strip hole after the first bolt is placed, and the second bolt and the locking hole can be limited through the cooperation of the second bolt and the locking hole, so that the first bolt is in a locking state after the second bolt is inserted, and the first bolt is prevented from moving up and down; the first bolt can block the fixing holes on the upper base and the lower base after being locked, so that other people are prevented from pulling out the first bolt and unscrewing the bolt at the fixing hole under the state that the second bolt is locked, the structure is simple, and the locking effect is good; through the cooperation of the fixed hole and the first bolt, the bolt for connecting the rear frame door can directly penetrate through the upper base and the lower base to be fixed, so that the invention can be directly installed on the rear frame door of the existing switch cabinet, the installation difficulty of a user is reduced, and the applicability of the invention is improved. In addition, the invention can make each part be processed and formed by a flat plate by further limiting the appearance of each part, thereby reducing the production cost and processing difficulty of the invention. Therefore, the invention can be directly arranged on the rear cabinet door of the switch cabinet and has the characteristics of simple structure and good locking effect.
Drawings
FIG. 1 is a schematic diagram of the structure of the present invention;
fig. 2 is a top view of the lower base.
The marks in the drawings are: the novel lock comprises a 1-upper base, a 2-lower base, a 3-first bolt, a 4-second bolt, a 5-lock body, a 6-fixing hole, a 201-lock hole, a 202-limiting step, a 301-baffle plate, a 302-strip hole, a 401-clamping block and a 402-folded plate.
Detailed Description
The invention is further illustrated by the following figures and examples, which are not intended to be limiting.
Examples. The utility model provides a switch cabinet is hasp structure for back frame door constitutes as shown in fig. 1, including fixing the last base 1 and the lower base 2 on back frame door respectively, go up and be connected with first bolt 3 between base 1 and the lower base 2, be equipped with second bolt 4 on the lower base 2, second bolt 4 upper end is located lower base 2 top, and second bolt 4 lower extreme extends to lower base 2 below and is connected with lock body 5, go up all be equipped with on base 1 and the lower base 2 with bolted connection's fixed orifices 6, the bolt is connected gradually back frame door and switch cabinet body after passing base 1 or lower base 2.
The first bolt 3 is vertically arranged on the upper base 1 and the lower base 2 outside the fixing hole 6.
A lock hole 201 is formed in the lower base 2, a limit step 202 is formed in one side of the lock hole 201, the lower end of the first plug pin 3 extends to the lower side of the limit step 202, and the second plug pin 4 penetrates through the lock hole 201 to be connected with the lock body 5; the lock body 5 can be a mechanical coded lock or padlock. .
The top of the first bolt 3 is provided with a baffle 301 positioned above the upper base 1, and the middle part of the first bolt 3 is provided with a strip hole 302.
The fixture block 401 is arranged on one side of the second bolt 4, the fixture block 401 is arranged in the strip hole 302, and the bottom of the fixture block 401 is mutually attached to the bottom of the strip hole 302.
