Abstract

The utility model relates to a mechanical interlocking device, which comprises an interlocking fixed plate, an interlocking block and a touch block, wherein the interlocking fixed plate is connected with the interlocking block in a rotating way through an adjusting stud, the touch block comprises a touch block base and a contact plate, the contact plate is connected with the touch block base through a plurality of fixed studs, when the device moves downwards, and the touch block collides with the rear end of the interlocking block, so that the interlocking block is automatically opened. The mechanical interlocking device has beneficial effects of simpleness in structure, convenience in use, low production cost, strong safety, long service life, and difficulty in damaging of working state and wide application range.

Description

A kind of mechanical interlocking device

Technical field

The utility model relates to a kind of mechanical interlocking device.

Background technology

In the practical application at present, the inter locking gear that is installed on the safety door uses spring mostly, and the use medi-spring damages easily, causes the inter locking gear afunction, and this kind application range of products is narrower, can not be general to the cage door.

The utility model content

Problems such as the purpose of the utility model provides a kind of mechanical interlocking device, and the mechanical interlocking device that can solve on the present safety door is short service life, and mode of operation is fragile, and can be widely used on safety door and the cage door.

The purpose of the utility model realizes through following technical scheme:

A kind of mechanical interlocking device comprises chain adapter plate, interlock block and collision block, and chain adapter plate and interlock block are rotationally connected through regulating double-screw bolt; Collision block comprises collision block base and contact plate, and contact plate is connected with the collision block base with the combination of captive nut through the plurality of fixed double-screw bolt.

The beneficial effect of the utility model is: simple in structure, easy to use, cost of manufacture is low, high safety, and long service life, mode of operation is not fragile, has wide range of applications.

Description of drawings

According to accompanying drawing the utility model is done further explain below.

Fig. 1 is the structural representation of the described a kind of mechanical interlocking device of the utility model embodiment;

Fig. 2 is the structural representation of the blocking of the described a kind of mechanical interlocking device of the utility model embodiment.

Among the figure:

1, chain adapter plate; 2, interlock block; 3, collision block; 31, contact plate; 4, collision block base; 5, captive nut; 6, fixed bolt; 7, regulate double-screw bolt; 9, door edge.

The specific embodiment

Shown in Fig. 1-2, a kind of mechanical interlocking device shown in the utility model embodiment comprises chain adapter plate 1, interlock block 2 and collision block 3, and chain adapter plate 1 is rotationally connected through regulating double-screw bolt 7 with interlock block 2; Collision block 3 comprises collision block base 4, contact plate 31, and contact plate 31 is connected with collision block base 4 through the combination of plurality of fixed double-screw bolt 6 and captive nut 5.Regulate captive nut and can adjust the distance of contact plate 31 and collision block base 4.

During concrete the use, as shown in Figure 2, when cage rose, contact plate 31 separated with interlock block 2, and interlock block 2 front ends catch on safety door because deadweight falls, and door can't be played a protective role from external opening.

As shown in Figure 1, contact plate 31 engages with interlock block 2 when cage descends, and interlock block 2 rear ends and contact plate 31 touchings also make interlock block 2 rotate through regulating double-screw bolt 7; The front end of interlock block 2 lifts; Break away from door along 9, thereby can open safety door, play chain effect.

The utility model is not limited to above-mentioned preferred forms; Anyone can draw other various forms of products under the enlightenment of the utility model; No matter but on its shape or structure, do any variation; Every have identical with a application or akin technical scheme, all drops within the protection domain of the utility model.

Claims
