Embodiment Construction

[0019] The present invention will be described in detail below in conjunction with accompanying drawing, as figure 1 , 2 , 3 shows: the present embodiment includes the handle 1 inlaid on the cylinder 2, the upper and lower positions of the cylinder 2 respectively have an upper stop pin 3 and a lower stop pin 6, and the cylinder 2 passes through the guide rail bracket 4 The round hole of the plane is inserted into the spring 5 again, and the lower stop pin 6 penetrates into the cylinder 2 and is in the oblong hole on the side plane of the guide rail bracket 4; there is a fixed bracket 9 below the guide rail bracket 4, and the pin shaft 8 passes through it. Through the holes of the guide rail bracket 4 and the fixed bracket 9, use the cotter pin 7 to penetrate the 8 holes of the pin shaft and lock it; by pulling the handle 1, the linkage cylinder 2 moves up and down in the direction of the oblong hole of the guide rail bracket to lock.

[0020] The handle 1 is made of rubber ma...

Abstract

The invention discloses a hand-operated locking mechanism, and belongs to the technical field of machinery locking device. The hand-operated locking mechanism comprises a handle; the handle is embedded onto a cylindrical body; the upper part and the lower part of the cylindrical body are provided with an upper stop pin and a lower stop pin; the cylindrical body is designed to pass through a circular hole on an upper plane of a guide rail support, and is sleeved with a spring; the lower stop pin is designed to pass through the cylindrical body, and pass through a long circular hole on the sideplane of the guide rail support; the lower part of the guide rail support is provided with a fixing support; a pin shaft is designed to pass through the guide rail support and holes of the fixing support; a cotter pin is designed to pass through a pin shaft hole for locking; when the handle is pulled, the cylindrical body is driven to move upward and downward along the long circular hole directionof the guide rail support for locking. The advantages are that: the structure is simple; design is skillful; opening and locking are convenient; mechanism locking is adopted, failure or loosen is noteasily caused, and the hand-operated locking mechanism is safe and reliable.

Description

technical field [0001] The invention relates to a manual locking mechanism, which belongs to the technical field of mechanical locking devices. Background technique [0002] In the daily production work of the substation, the high-voltage switchgear is frequently operated, and the door of the switchgear needs to be opened and closed during the operation. Use existing common key, there are many deficiencies. For example, it takes a long time to open and cannot be opened, etc., which affects the operation time and ultimately affects the user's power transmission. Especially when it comes to the operation of bus stop and power transmission, which involves many feeders and a wide range of users, it can open and close cabinet doors quickly and reliably, improve power transmission efficiency, and ensure customers' power consumption. Therefore, it is necessary to develop a fast manual mechanical locking mechanism to solve the above problems. Contents of the invention [0003] ...
