Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention, and should not be construed as limiting the present invention.

The first embodiment is as follows:

the utility model provides an elevator safety frame, includes inside casing 1 and frame 2, is provided with between inside casing 1 and the frame 2 and resets piece 3 and micro-gap switch 4, wherein:

the outer frame 2 is connected with the inner frame 1 in a floating way, the reset piece 3 is arranged on the outer frame 2, and the micro switch 4 is arranged on the inner frame 1;

the outer frame 2 is provided with a containing groove 5 for installing the reset piece 3; the accommodating groove 5 is a strip arranged on the inner side of the outer frame 2, a first gap 10 is milled at the bending position of the outer frame 2 to facilitate the bending of the outer frame 2, and a plurality of gaps 7 are also arranged on the accommodating groove 5, so that the strip accommodating groove 5 can be divided into a plurality of accommodating grooves 5, and the gaps 7 are used for accommodating the micro switch 4; the outer frame 2 is also provided with a waist-shaped hole 11, and the outer frame is fixed on the car bottom through a screw 12 passing through the waist-shaped hole 11;

the inner frame 1 is provided with a mounting plate for mounting the microswitch 4, and the mounting plate is milled into a second gap 13 at the bending position of the inner frame 1, so that the inner frame is convenient to bend, and the upper part and the lower part of the inner frame 1 are respectively provided with a first closing edge 8 and a second closing edge 9, so that the whole body is more attractive;

the microswitch 4 is electrically connected with the processor, so that after the frame 2 is pressed downwards to trigger the microswitch 4, the processor can sense the state of the microswitch 4, and the microswitch 4 is a conventional product in the prior art, so that the microswitch 4 is not developed in detail;

the reset piece 3 comprises three parts, namely an arch part 3.1, a base 3.2 and a reinforcing part 3.3, wherein the arch part 3.1 is arranged on the base 3.2, and the length of the base 3.2 is greater than that of the arch part 3.1, so that spaces are arranged on two sides of the base 3.2 after the arch part 3.1 is arranged on the base 3.2, the reinforcing parts 3.3 are respectively arranged in the spaces, and the arch part 3.1, the base 3.2 and the reinforcing part 3.3 are integrally formed, so that the processing is more convenient; the theory of operation that resets 3 is, when frame 2 atress pushes down, resets 3 and also can be by extrusion deformation, and when the external force that frame 2 received disappeared, resets 3 and will automatic re-setting, and then drive frame 2 automatic re-setting.

Example two:

the difference from the first embodiment is that in the second embodiment, the reset piece 3 is further provided with a step 3.4, and the step 3.4 is positioned between the arch part 3.1 and the base 3.2, that is, the step 3.4 can be formed by making the width of the arch part 3.1 smaller than that of the base 3.2, as shown in fig. 5, the right side of the arch part 3.1 is vertically flush with the right side of the base 3.2, and the left side of the arch part 3.1 is staggered with the base 3.2 to form the step 3.4, so that when the arch part 3.1 is extruded and deformed, the deformed arch part 3.1 can be extruded to the step 3.4 to prevent the arch part 3.1 from being crushed, and thus the reset piece 3 is not easy to be damaged when in use; and set up protruding muscle 6 on frame 2, step 3.4 can cooperate with protruding muscle 6 like this for reset 3 can be fine fix in storage tank 5.

Example three:

the difference with the first embodiment is that the depth of the receiving groove 5 in the third embodiment is the same as the height of the base 3.2, which is equivalent to completely exposing the arch part 3.1 outside, so that the overall elastic force of the reset piece 3 is better, the reset effect is better, and the base 3.2 is not squeezed to cause excessive squeezing.
