It is noted that the following examples are only for explaining the present utility model and are not to be construed as limiting the present utility model.
Example 1:
a sign for use in safety isolation operations of a hydropower station system, comprising: the device comprises a base 3, a coil spring strip 2, a hanging rope 1 and a sliding cover 4, wherein two accommodating cavities 5 are formed in the surface of the base; two wire grooves are formed in the surface of the base, one ends of the two wire grooves are correspondingly communicated with the two accommodating cavities respectively, and the other ends of the two wire grooves are communicated with the end parts of the base respectively; the two coil spring strips are respectively arranged in the accommodating cavity in a corresponding manner.
Two auxiliary spring strips are respectively arranged in the accommodating cavity of the base, one end of each spring strip is fixed at the center of the accommodating cavity of the base, a rope penetrating hole is formed in the other end of each spring strip, the hanging rope is connected to each spring strip, the hanging rope is internally coiled according to the tension characteristic of each spring strip, after force is accumulated in the internal coiling, one part of the hanging rope is wound on each spring strip, and after both ends of the hanging rope are wound on the accumulated spring strips, the rest parts of the hanging rope are placed in a wire groove.
The sliding cover is arranged on the base in a sliding manner, and the wire groove and the accommodating cavity are shielded or exposed through sliding; when the pull rope is pulled out and stretched, the elastic force born by the coil spring strip is smaller than or equal to the gravity of the base and the sliding cover.
The signboard is characterized in that a hanging rope on the signboard is designed to be telescopic. Under the tension action of two auxiliary spring strips in the signboard, the hanging rope is automatically retracted into the signboard, and when the signboard is used, the hanging rope is manually pulled out, the whole weight of the signboard overcomes the tension of the internal spring strips and is hung on the equipment according to the requirement.
The signboard is composed of a base, a sliding cover and the like, and the sliding cover can be used for installing and maintaining a coil spring strip and a hanging rope on the base after sliding out. The hanging rope is automatically retracted through the action of the internal coil spring, so that the hanging rope is effectively protected, and the signboard is more convenient and attractive in storage.
In some embodiments, the two receiving cavities are symmetrically disposed. One side of the wire groove is tangent to the accommodating cavity, and a rounded corner is arranged at the joint of the other side of the wire groove and the accommodating cavity. Thus, the two ends of the pull rope are uniformly stressed, and the extension and contraction of the coil spring are facilitated.
In some embodiments, the depth of the wire groove is the same as the depth of the receiving cavity. The width of the spring strip is less than or equal to the depth of the receiving cavity. The coil spring strip is ensured not to be coiled in the accommodating cavity and can only shrink or stretch in a single-layer direction.
Referring to fig. 2-5, a limit groove is formed between the two wire grooves, the limit groove is communicated with the end part of the base, the limit groove is respectively communicated with the two wire grooves, and the middle part of the hanging rope is limited through the limit groove. The design of the limit strip can enable the stay rope between the two wire grooves to be in the covering of the sliding cover, so that the stay rope cannot be exposed at the end part when the sliding cover is not used, and one protection and protection effect on the stay rope can be achieved.
In some embodiments, the side walls on two sides of the base are provided with clamping grooves, the clamping grooves are provided with a first horizontal plane, the first horizontal plane is provided with inwards concave positioning grooves 6, two sides of the sliding cover are provided with clamping strips matched with the clamping grooves, the clamping strips are provided with a second horizontal plane, and the second horizontal plane is provided with positioning columns 7 matched with the positioning grooves. The top surface of the positioning column is an arc-shaped surface.
The sliding cover is in sliding fit with the base through a wedge-shaped rail, and icons and Chinese characters for prohibiting closing are printed on the surface of the sliding cover. After the sliding cover is matched and connected with the base, the sliding cover is prevented from loosening and falling off, and the sliding cover is fixed by the matching of the positioning column and the positioning groove. Preventing it from falling off.
Still referring to fig. 1, the end of the base is provided with a notch penetrating the base in the thickness direction, and the distance between the bottom of the notch and the nearest end of the base is greater than the distance between the limiting groove and the nearest end of the base. The pull rope can be conveniently taken out through the notch.
When the signboard is used, the hanging rope is pulled out from the notch at the upper part of the base, and the signboard hung on the equipment cannot retract because the dead weight of the signboard is basically matched with the tension of the coil spring strip. When the hanging rope is taken down, the hanging rope automatically retracts under the tension of the coil spring strip.
The foregoing description of the preferred embodiments of the utility model is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the utility model.
