Description

Technical Field

[0001] The utility model relates to the field of snap-on identification plate devices, in particular to a rotatable clamping and fixing mechanism and a labor-saving snap-on identification plate device. Background Art

[0002] When a hydropower station is undergoing maintenance or troubleshooting, operators are not only required to arrange safety measures on site, but also to hang signs at corresponding locations to prevent station staff from going to the wrong interval during maintenance or troubleshooting. This includes hanging a snap-on sign on the corresponding switch after disconnecting the circuit breaker, which reads "Do not close the switch, someone is working."

[0003] At present, the snap-on signboards of power stations mainly adopt the form of two elastic iron wires with a submerged buckle structure, that is, the two elastic iron wires need to be deformed to a certain extent and have a certain tilt angle before they can be fully assembled. However, the iron wires are not fixed in the signboard. When the wind blows, the signboard shakes up and down, which will cause certain dangers to the staff. In addition, the staff use their fingers to directly touch and pinch the two iron wires to achieve the deformation effect. However, the cross-section of the iron wire is small, and its elastic modulus is usually affected by factors such as the iron wire material, manufacturing process and ambient temperature. As a result, when installing such signboards, operators usually encounter the situation that the iron wire is difficult to pinch together, or even scratch their fingers. Utility Model Content

[0052] Specifically, the mounting plate 401a is fixedly installed around the inner wall of the identification plate 101, and a mounting column 401b is fixedly installed on the side of the mounting plate 401a away from the identification plate 101, and mounting grooves 401c are symmetrically provided on both sides of one end of the mounting column 401b away from the mounting plate 401a, and an elastic block 401d is fixedly connected in the mounting groove 401c, and the elastic block 401d includes a spring and a trapezoidal block 402d, wherein a partition 401e is placed on the side of the mounting plate 401a away from the identification plate 101, and mounting holes 401f are provided around the partition 401e, and the position of the mounting hole 401f corresponds to the position of the mounting column 401b.

[0053] Furthermore, the labor-saving component 402 includes a sliding hole 402a opened on the partition 401e, a sliding rod 402b arranged in the sliding hole 402a, a button 402c installed on one end of the sliding rod 402b, and a trapezoidal block 402d installed on the other end of the sliding rod 402b; wherein, a first spring 402e is arranged on the outer wall of the sliding rod 402b, a second spring 402f is arranged under the trapezoidal block 402d, and locking rings 402g are connected to both ends of the second spring 402f.

[0054] Specifically, a sliding hole 402a is opened in the middle of the partition 401e, and a sliding rod 402b is placed in the sliding hole 402a. The end of the sliding rod 402b away from the identification plate 101 is fixedly connected to a button 402c, and the button 402c is a square plate. The end of the sliding rod 402b close to the identification plate 101 is fixedly connected to a trapezoidal block 402d, wherein a first spring 402e is arranged on the outer wall of the sliding rod 402b, and the first spring 402e is fixedly connected between the partition 401e and the button 402c.

[0055] The rest of the structure is the same as that of Example 2.

[0056] Operation process: When in use, align the partition 401e with the elastic block 401d and press it. The inclined surface of the elastic block 401d is forced to move into the installation groove 401c. When the elastic block 401d completely slides into the installation groove 401c, the partition 401e moves to the bottom of the installation column 401b. At this time, the elastic block 401d is no longer stressed and begins to restore the initial state, and the partition 401e is fixed in the identification plate 101. Press the elastic block 401d to move into the installation groove 401c to remove the partition 401e. Press the button 402c. The button 402c drives the trapezoidal block 402d on the slide bar 402b to move into the inside of the identification plate 101. The inclined surface of the trapezoidal block 402d pushes the two wires 104 to move to both sides, so that the lower part of the wire 104 is separated and the upper part of the wire 104 is driven to gather. At this time, The iron wire 104 is placed on the switch device. At the same time, the button 402c squeezes the first spring 402e, causing it to be compressed. The bottom of the iron wire 104 separates so that the second spring 402f is stretched. The button 402c is released, and the first spring 402e rebounds to drive the trapezoidal block 402d and the button 402c to return to their initial positions. The second spring 402f returns to its initial state and pulls the bottom of the iron wire 104 together, and separates the top of the iron wire 104. At this time, the identification plate 101 can be fixedly installed on the switch device. The entire structure is simple in design, easy to manufacture and mass produce, and easy to operate. The structure can be operated with one hand to achieve one-button installation or removal of the identification plate 101, which also reduces the influence of the uncertainty of the elastic modulus of the iron wire 104 on the installation and removal of the identification plate 101, improves work efficiency, and reduces the risk of scratches on personnel.
