Description

Technical Field

[0001] The invention relates to the field of locks, and in particular to a tongue transmission mechanism of an intelligent distribution box lock. Background Art

[0002] With the continuous development of power technology, the application scenarios of distribution box equipment are becoming more and more extensive, and its scientific management and safe use of electricity have attracted much attention. At present, there are still some shortcomings in the application of distribution box equipment. In order to make up for the safety problems that arise, locks are often used to close the distribution box.

[0003] The lock tongue of the existing locks mostly acts directly on the box body, and the existing lock tongue is mostly directly installed on the lock shaft. When the lock is pried, the force applied to the tongue will be directly transmitted to the lock body and the box body, which may easily cause safety problems such as damage to the lock body and the box body. Summary of the invention

[0004] In order to overcome the problem that when the lock tongue of the existing lock is pried, the force exerted on the turning tongue is directly applied to the lock body and the box, causing the lock body and the box to be deformed under the force, thereby causing damage to the entire lock body and the box, thereby affecting the safe use of the distribution box.

[0005] The technical solution of the present invention is: a cam transmission mechanism of an intelligent distribution box lock, comprising a box door panel, a mounting back panel connected to the box door panel, a cam assembly connected to the mounting back panel, a lock assembly movably connected to the cam assembly, and a box connected to the lock assembly;

[0006] The tongue assembly includes a tongue shaft sleeved on the mounting back plate, a commutator segment sleeved on the tongue shaft, a gasket arranged on the upper end of the commutator segment, a tongue sleeved on the tongue shaft, and a first mounting nut with a clearance fit on the tongue shaft.

[0007] Preferably, the rotary tongue shaft comprises a threaded shaft with a clearance fit on the first mounting nut, a square boss connected to the threaded shaft, a fixing boss connected to the square boss, and a first square hole opened on the fixing boss.

[0008] Preferably, the commutator segment comprises a commutator segment ring sleeved on the threaded shaft, a second square hole formed on the commutator segment ring, and a limit platform connected to the commutator segment ring.

[0009] Preferably, the lock assembly includes a lock arranged at the rear end of the tongue, a second reinforcement plate connected to the lock, a mounting stud movably connected to the second reinforcement plate, a first reinforcement plate connected to the mounting stud, and a second mounting nut clearance-fitted on the mounting stud.

[0010] Preferably, the second reinforcement plate is welded to the lock buckle, and four mounting holes are provided on the second reinforcement plate, and the mounting holes and the mounting studs are arranged in a one-to-one correspondence.

[0011] Preferably, the second reinforcement plate, the box body and the first reinforcement plate are connected via mounting studs and second mounting nuts.

[0012] Preferably, two limit platforms are provided, the two limit platforms are arranged symmetrically on a circle, and the limit platforms are connected to the commutator ring.

[0013] Preferably, the rotating tongue and the threaded shaft are connected to the gasket via a first mounting nut.

[0014] Beneficial effects of the present invention:

[0015] 1. The present invention provides a tongue assembly, which specifically includes a tongue shaft, a mounting back plate, a reversing plate, a gasket, a tongue, and a first mounting nut. The tongue shaft is rotatably mounted and passes through the mounting back plate. A reversing plate is mounted to the right. The reversing plate cooperates with a limiter on the mounting back plate to enable the tongue to rotate 90° and realize the reversal of opening the door to the left and right. A gasket is mounted to the right. The position of the tongue can be adjusted by increasing or decreasing the number and height of the gaskets to adapt to different door boxes. The tongue is tightly mounted on the tongue shaft through the first mounting nut. Since the tongue and the tongue shaft are mounted on the mounting back plate, the tongue transmits force to the mounting back plate when picking the lock. The mounting back plate is in direct contact with the box body and has a large contact surface. Therefore, the force transmitted to the box body and the lock body is greatly reduced. This design can not only effectively prevent the lock body from being damaged when picking the lock, but also has the function of protecting the box body.

[0016] 2. The present invention provides a lock assembly, which specifically includes a first reinforcement plate, a second reinforcement plate, a lock, etc. The lock is welded to the second reinforcement plate, and the first reinforcement plate passes through the box and is fixedly connected to the second reinforcement plate. After locking, compared with the traditional tongue that directly acts on the box, the tongue of the present invention directly blocks the lock. When picking the lock, the force transmitted by the tongue directly acts on the first reinforcement plate and the second reinforcement plate through the lock. The contact areas between the two reinforcement plates and the box are large, and the transmitted force is dispersed by the reinforcement plates, and the force acting on the box is greatly reduced, thereby effectively avoiding deformation and damage caused by the thin box when picking the lock. Furthermore, compared with the traditional force transmission path of box-lock body-tongue-box, the force transmission method of box-mounting back plate-tongue-lock-reinforcement plate-box of the present application can further improve the service life of the entire equipment.

[0021] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0022] A cam transmission mechanism for an intelligent distribution box lock, according to Figure 1-3 As shown, it includes a box door panel 1, a mounting back panel 2 connected to the box door panel 1, a tongue assembly 3 connected to the mounting back panel 2, a lock assembly 4 movably connected to the tongue assembly 3, and a box 5 connected to the lock assembly 4;

[0023] The tongue assembly 3 includes a tongue shaft 31 sleeved on the mounting back plate 2, a commutator segment 32 sleeved on the tongue shaft 31, a gasket 33 arranged on the upper end of the commutator segment 32, a tongue 34 sleeved on the tongue shaft 31 and a first mounting nut 35 with a clearance fit on the tongue shaft 31.

[0024] It should be noted that the tongue shaft 31 is rotatably installed and passes through the mounting back plate 2. A reversing piece 32 is mounted to the right, and a gasket 33 is mounted to the right. The position of the tongue 34 can be adjusted by increasing or decreasing the number and height of the gasket 33 to adapt to different door cases. The tongue 34 is tightly mounted on the tongue shaft 31 through the first mounting nut 35. Since the tongue 34 and the tongue shaft 31 are mounted on the mounting back plate 2, the tongue 34 transmits force to the mounting back plate 2 when the lock is pried. The mounting back plate 2 is in direct contact with the box body 5 and has a large contact surface. Therefore, the force transmitted to the box body 5 and the lock body is greatly reduced. This design can not only effectively prevent the lock body from being damaged when the lock is pried, but also has the function of protecting the box body.

[0025] according to Figure 2 As shown, the tongue shaft 31 includes a threaded shaft 313 with a clearance fit on the first mounting nut 35, a square boss 312 connected to the threaded shaft 313, a fixed boss 311 connected to the square boss 312, and a first square hole 314 opened on the fixed boss 311.

[0026] according to Figure 2 As shown, the commutator segment 32 includes a commutator segment ring 323 sleeved on the threaded shaft 313 , a second square hole 322 formed on the commutator segment ring 323 , and a limit platform 321 connected to the commutator segment ring 323 .

[0029] It should be noted that the tongue of the present invention is directly blocked on the lock buckle. When picking the lock, the force transmitted by the tongue acts directly on the first reinforcement plate and the second reinforcement plate through the lock buckle. The contact areas between the two reinforcement plates and the box body are large. After the transmitted force is dispersed by the reinforcement plates, the force acting on the box body is greatly reduced, thereby effectively avoiding deformation and damage caused by the thin box body when picking the lock.

[0030] according to Figure 1 and Figure 3 As shown, the second reinforcing plate 42 is welded to the lock buckle 43 , and four mounting holes are provided on the second reinforcing plate 42 , and the mounting holes and the mounting studs 45 are arranged in a one-to-one correspondence.

[0031] according to Figure 1 and Figure 3 As shown, the second reinforcing plate 42 , the box body 5 and the first reinforcing plate 41 are connected via mounting studs 45 and second mounting nuts 44 .
