Problems solved by technology

[0003] The interlocking propulsion mechanism of the hand-pull operation mode and the hand-crank operation mode are currently used in drawer units on the market. The interlocking propulsion mechanism of the hand-pull operation mode is limited to the drawer units with a current level below 250A and a current level of 400A. Hand-pull operation in a drawer unit with a current level of 400A, the operation resistance has increased significantly, and the hand-pull operation is a bit difficult, but it is even more difficult to perform a hand-pull operation in a drawer unit with a current level of 630A and 800A
[0004] The hand-operated interlocking propulsion mechanism commonly used in drawer units adopts multi-turn cranking to increase force. Although the operation resistance is small, it is not fast and convenient compared with manual operation, and the drawer units with current levels of 630A and 800A Among them, the test position of the multi-turn interlocking propulsion machine is not set, and it is easy to pass the position during operation. Even if there is a sound prompt, there is no obvious positioning

Embodiment 1

[0062] Embodiment 1: as figure 1 As shown in ~9C, a three-position positioning interlocking mechanism traction lock plate anti-misoperation boosting mechanism can realize the functions of three-position positioning display, switch closing lock, and propulsion mechanism locking.

[0063] The three-position positioning interlocking mechanism traction lock plate anti-misoperation boosting mechanism includes a position positioning interlocking mechanism, a position indicating mechanism and a boosting boosting mechanism, the boosting boosting mechanism is a spiral boosting boosting mechanism, and the position positioning interlocking mechanism is used The drawer 22 is positioned and unlocked in cooperation with the position locating piece 14 on the unit room shelf, and the screw booster mechanism is used to cooperate with the groove-shaped locating piece 16 on the unit room shelf to perform the rocking operation of the drawer 22. A traction locking plate 12 is set between the posit...

Embodiment 2

[0095] Embodiment 2: On the basis of Embodiment 1, the traction lock plate 12 and the screw power boosting mechanism are cancelled, and the interlocking mechanism of Embodiment 2 can satisfy the application functions of the drawer 22 in three-position pushing and pulling out by hand Standard technical requirements. However, it is only used in drawers 22 with current levels of 125A, 250A, and 63A. In these drawers 22 with current levels, the plug pressure of the main and auxiliary circuit plugs is not greater than 900N, which is relatively in line with manual operation requirements.

[0096] However, there are many types of drawer unit structures and current ratings. Only the hand-pull and hand-pull operation methods of this embodiment 2 cannot meet the push operation of the drawer 22 with a high current level. It is necessary to add a screw booster mechanism and a traction lock plate. The three-position positioning interlock mechanism traction lock plate anti-misoperation powe...

Embodiment 3

[0098] Chinese patent application document CN110890711A discloses a removable three-position operating functional unit, which discloses a lever-increasing propulsion mechanism, which includes a lever-increasing upward propulsion mechanism 27 and the push mechanism 28 under the lever boost, the operating tool 29 of the lever operation port of the push mechanism 27 and the lever boost lower push mechanism 28 inserted into the lever boost carries out the push operation of the drawer 22.

[0099] This embodiment 3 is obtained on the basis of the structural principle of embodiment 1 in combination with the lever-increased upper propulsion mechanism and the lever-intensified lower propulsion mechanism disclosed in the Chinese patent application document CN110890711A. The upper operating port formed by the rotating shaft assembly is the lever-enhancing upward propulsion mechanism, and the lower operating port formed by the double-column rotating shaft assembly is the lever-enhancing l...

Abstract

The invention relates to a three-position positioning interlocking mechanism traction lock plate anti-misoperation reinforcement mechanism assembly and a drawer unit. The three-position positioning interlocking mechanism traction lock plate anti-misoperation boosting mechanism assembly comprises a three-position positioning interlocking mechanism, a traction lock plate and a boosting propelling mechanism, the three-position positioning interlocking mechanism locks the boosting propelling mechanism through the traction lock plate, and anti-misoperation is achieved. When the three-position positioning interlocking mechanism drags the lock plate anti-misoperation boosting mechanism to move from the separation position to the test position along with the drawer and is positioned, the boostingpropelling mechanism starts to enter a matching state. The drawer unit comprises the three-position positioning interlocking mechanism traction lock plate anti-misoperation reinforcement mechanism assembly. The beneficial effects are that three-position positioning is reliable, the boosting propelling mechanism has an anti-misoperation locking function, and operation can be carried out only afterlocking is opened. The drawer unit with the mechanism assembly has two operation functions of hand pulling operation and force increasing operation, the operation is simplified, and the operation is still easy and convenient.

Description

technical field [0001] The invention relates to the technical field of interlocking propulsion of low-voltage switch complete sets of equipment, in particular to a three-position positioning interlocking mechanism traction lock plate anti-misoperation boosting mechanism, an assembly and a drawer unit. Background technique [0002] In the technical field of drawer interlocking propulsion mechanism for complete sets of low-voltage switchgear, according to the requirements of application standards, the interlocking propulsion mechanism should have the functions of three-position positioning and three-position indication. Operation mode, combined operation mode of hand pulling and hand cranking. [0003] The interlocking propulsion mechanism of the hand-pull operation mode and the hand-crank operation mode are currently used in drawer units on the market. The interlocking propulsion mechanism of the hand-pull operation mode is limited to the drawer units with a current level bel...
