[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-6 The utility model discloses a safety button cover, comprising a cover body 1, a groove is provided at one end of the cover body 1, a clamping mechanism 2 for clamping with the button is arranged in the groove; the clamping mechanism 2 comprises a guide plate 21 rotatably arranged in the groove, a first spiral guide groove is provided on the side of the guide plate 21 close to the opening direction of the groove, at least three sliders 22 that can slide along the first spiral guide groove are arranged on the guide plate 21, a clamping rod 23 is arranged on the side of the slider 22 away from the guide plate 21, and the clamping mechanism 2 also comprises a guide rod 24 fixedly arranged in the groove for guiding the slider 22 to move toward and away from the axis of the guide plate 21;

[0024] The cover body 1 is provided with a driving mechanism 3 for driving the guide plate 21 to rotate.

[0025] The utility model provides a clamping mechanism 2 in the cover body 1, so that after the cover body 1 is sleeved on the outside of switch buttons of various different diameters, the guide plate 21 can be rotated forwards and backwards by the driving mechanism 3, and the distance between the clamping rods 23 can be adjusted so that the clamping rods 23 clamp the switch buttons, ensuring that the cover body 1 can be stably fixed on switch buttons of different models. Before repairing the equipment, the maintenance personnel can provide additional protection for the switch buttons by installing the cover body 1 on the corresponding switch buttons, thereby reducing the probability of accidental touch and improving the maintenance safety.

[0026] In a specific implementation, in order to improve the clamping stability of the clamping rod 23, a rubber sleeve may be added to the outside of the clamping rod 23 to increase the clamping friction.

[0027] In one embodiment, the driving mechanism 3 includes a linkage shaft 31 fixedly arranged on the side of the guide plate 21 away from the slider 22, one end of the linkage shaft 31 away from the guide plate 21 passes through the cover body 1 and extends to the outside of the cover body 1, a handle 32 is sleeved on the linkage shaft 31, a tension spring 33 with one end connected to the linkage shaft 31 is arranged in the handle 32, a second spiral guide groove 34 is provided in the handle 32, a guide bead 35 capable of moving along the second spiral guide groove 34 is fixedly arranged on the linkage shaft 31, a limit rod 36 inserted into the cover body 1 is arranged on the handle 32, and a slide groove for the limit rod 36 to move along the axial direction is provided on the cover body 1;

[0028] When the end of the linkage shaft 31 outside the handle 32 is the longest, the distance between the multiple clamping rods 23 is the largest and the tension spring 33 is in a stretched state. When the tension spring 33 is in a natural state, the distance between the multiple clamping rods 23 is the smallest.

[0029] With this design, when the maintenance personnel install the safety button cover on the switch button, they only need to hold the cover body 1 with the index finger and middle finger of one hand, and then use the thumb to push the handle 32 to the side away from the cover body 1, so that the guide plate 21 can be driven to rotate multiple circles with the cooperation of the second spiral guide groove 34 and the guide bead 35, so that the multiple clamping rods 23 can expand to the maximum clamping state, and then the safety button cover can be installed on the switch button. After that, release the thumb to reset the handle 32 under the action of the tension spring 33, so that the clamping rod 23 can maintain the clamping force on the switch button for a long time under the action of the tension spring 33, thereby achieving the purpose of one-handed operation and flexible use.

[0030] In one embodiment, an identification plate 4 is rotatably provided at one end of the handle 32 away from the linkage shaft 31 through a bearing. The identification plate 4 consists of an upper semicircular disk and a lower semicircular disk. A hollow groove is provided on the side of the upper semicircular disk close to the handle 32 .

[0031] This design allows maintenance personnel to engrave a "No Press During Maintenance" sign on the sign 4 to remind non-maintenance personnel not to remove the safety button cover at will, thereby further improving maintenance safety. At the same time, since the sign 4 is rotatably set on the handle 32 and the upper and lower parts have different weights, after the safety button cover is installed on the switch button from different angles, the "No Press During Maintenance" sign on the sign 4 can be driven to rotate to a horizontal state due to the shift in the center of gravity, which is convenient for personnel to read.

[0032] In a specific implementation, in order to improve the integrity of the safety button cover, a recess is formed at one end of the handle 32 away from the linkage shaft 31, and the identification plate 4 is installed in the recess.

[0033] In one embodiment, a telescopic adjustment ring 5 threadedly connected to the cover body 1 is sleeved on one end of the cover body 1 away from the driving mechanism 3 .

[0034] In this design, when facing a mushroom-head switch button, since the movable part of the mushroom-head switch button is the entire exposed part, only the safety button cover is placed on the switch button and cannot prevent it from being pressed further. By rotating the telescopic adjustment ring 5, the telescopic adjustment ring 5 is moved toward the side of the cabinet where the switch button is installed until it is pressed against the cabinet. This operation method can prevent the safety button cover from moving, so that the safety button cover can also be used on the mushroom-head switch button.

[0035] In one embodiment, a magnetic ring 6 is disposed at one end of the telescopic adjustment ring 5 away from the driving mechanism 3 .

[0036] This design allows the safety button cover to further improve installation stability by utilizing the adsorption of the magnetic ring 6 and the cabinet after it contacts the cabinet. At the same time, after the safety button cover is removed, it can be directly adsorbed to the side of the cabinet, thereby eliminating the need for maintenance personnel to carry it with them and making it convenient to use whenever they want.

[0037] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back...), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0038] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the utility model, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or suggesting their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0039] In addition, "plurality" means two or more.

[0040] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
