First embodiment

Referring to fig. 1-2, an emergency button device 001 provided in this embodiment includes a package box 100, an opening 110 is provided on one surface of the package box 100, a fixing plate 200 is embedded in the package box 100, a button 300 is provided on the fixing plate 200, and one end of the button 300 extends into the package box 100. The fixing plate 200 divides the packaging box 100 into a mounting area and a receiving area, wherein the mounting area is the area between the plane of the opening 110 in the packaging box 100 and the fixing plate 200, and the receiving area is the area formed by surrounding the surface of the fixing plate 200 away from the opening 110 and the inner wall of the packaging box 100; one end of the button 300 is located in the mounting area, and the other end is located in the receiving area.

In this embodiment, since the button 300 is located inside the package can 100, the package can 100 can protect the button 300, so that the button 300 is not directly exposed to the chemical environment, and the corrosive action of chemicals and other corrosive substances on the button 300 is greatly prevented, so that the occurrence probability of safety accidents can be reduced. The button 300 is disposed on the fixing plate 200, and the fixing plate 200 is embedded in the package box 100, so that the fixing plate 200 can well fix the button 300. In addition, since one end of the button 300 is disposed at the mounting area, the button 300 can be directly contacted through the opening 110 in use, so that the button 300 can be easily contacted to control a circuit.

In this embodiment, in order to enable the mounting board 120 to be clamped in the packaging box 100, an embedding board 111 is disposed around the periphery of the opening 110, a groove (not shown) for clamping the fixing board 200 is disposed in the embedding board 111, and the fixing board 200 is embedded in the packaging box 100 through the groove on the embedding board 111.

In this embodiment, in order to better enhance the stability of the button 300, some components are usually further disposed in the packaging box 100. For example, in this embodiment, the mounting board 120 is further disposed in the package box 100, the mounting board 120 is in surface contact with the fixing board 200, the fixing board 200 is provided with a first screw hole 210, a second screw hole 121 is disposed at a position of the mounting board 120 corresponding to the first screw hole 210, and the fixing board 200 is fixed on the mounting board 120 by a screw 211.

The mounting board 120 in the present embodiment can prevent the fixing board 200 from being excessively embedded in the package box 100; on the other hand, the fixing plate 200 and the mounting plate 120 in the package 100 cooperate such that the fixing plate 200 is within the package 100. Specifically, in the present embodiment, surface contact is formed between the fixing plate 200 and the mounting plate 120, and a first screw hole 210 is provided on the fixing plate 200, a second screw hole 121 is provided at a position of the mounting plate 120 corresponding to the first screw hole 210, and the fixing plate 200 is fixed on the mounting plate 120 by a screw 211; thus, the fixing bracket can be integrally fixed to the mounting plate 120 by passing the screws 211 through the first screw holes 210 and the second screw holes 121. More specifically, in the present embodiment, the number of the first screw holes 210 and the second screw holes 121 is four, and the first screw holes and the second screw holes 121 are uniformly distributed at four corners of the fixing plate 200 or the mounting plate 120, so that the stress at each position of the fixing plate 200 and the mounting plate 120 is ensured to be uniform, and the stability between the fixing bracket and the packaging box 100 can be better improved.

In this embodiment, in order to better protect the button 300, the following arrangement is also made for the fixing plate 200:

the surface of the fixing plate 200 away from the opening 110 (i.e., in the receiving area) is connected with the button cover 220, and the button cover 220 protrudes toward the inside of the package case 100 with respect to the fixing plate 200, and the button 300 is located in the button cover 220. The button cover 220 may function to accommodate the button 300 on the one hand, and on the other hand, the button cover 220 may also function to block chemicals from corroding the button 300 to some extent, so that the corrosion of the button 300 by the chemicals may be better reduced by the combined action of the button cover 220 and the package can 100. In this embodiment, the button cover 220 and the fixing plate 200 are welded together, which is advantageous in improving the stability of the emergency button device 001. In other embodiments, the button cover 220 may be detachably connected to the fixing plate 200, for example, by providing a slot on the fixing plate 200, and providing a snap structure corresponding to the slot on the edge of the button cover 220 for detachable connection; the detachable connection facilitates recycling of the button housing 220.

In addition, the mounting plate 120 in the present embodiment is also adapted, specifically, the mounting plate 120 is provided with the mounting hole 122, and the mounting hole 122 penetrates the mounting plate 120 along the thickness direction of the mounting plate 120, so that the button cover 220 can penetrate the mounting hole 122 and extend into the area of the receiving area, and the mounting plate 120 does not obstruct the mounting of the button cover 220. Thus, in the present embodiment, the aperture of the mounting hole 122 is generally not smaller than the size of the button cover 220, so that the button cover 220 can pass through the mounting hole 122 into the receiving area. In particular, in this embodiment, the aperture of the mounting hole 122 and the size of the button cover 220 are the same, so that the button cover 220 can just pass through the mounting hole 122 to enter the storage area, and meanwhile, due to the specific size, the mounting hole 122 on the mounting plate 120 can also play a role in fixing the button cover 220, so that the button cover 220 is difficult to shake, and the stability of the button cover 220 is improved.

In addition, in this embodiment, the button cover 220 is further provided with a button hole 221 for filling the button 300, the button 300 is disposed in the button hole 221, and a sealing ring (not shown in the figure) is further sleeved on the button 300, and the button 300 and the button hole 221 are sealed by the sealing ring. Thus, even if the button 300 is pressed, the entire button housing 220 and the button 300 are in a sealed state, which is advantageous in improving the service life of the emergency button device 001.

It should be noted that, in other embodiments, the button cover 220 may not be provided, but the size of the mounting hole 122 may be reduced as much as possible, and the button 300 may be accommodated by the mounting hole 122, so that the package can 100 still protect the button 300 from corrosion, but the protection effect is reduced and the fixing effect is reduced compared to the present embodiment.

The surface of the fixing plate 200 adjacent to the opening 110 (i.e., in the mounting area) is further provided with a blocking plate 230 for covering the button 300, and the blocking plate 230 is rotatable with respect to the fixing plate 200. The barrier 230 prevents the button 300 from being touched by mistake and also has an effect of protecting the button 300 from corrosion to some extent.

In this embodiment, the baffle plate 230 can rotate relative to the enclosure 100, which can be achieved specifically by:

an axle center hole 240 is formed on the surface of the fixing plate 200 close to the opening 110, and the axle center hole 240 is positioned right above the axis of the packaging box 100; an axle 250 is then inserted through the barrier plate 230 and into the axle hole 240, such that the barrier plate 230 is rotated relative to the enclosure 100 by pulling the barrier plate 230 under the force of an external force. When an emergency situation is encountered and power is to be cut off, the function of cutting off the power can be realized by pulling the baffle plate 230 to press the button 300; when no external force is applied to toggle the baffle 230, the baffle 230 can fall under the action of gravity, so that the opening 110 can be closed to prevent the button 300 from being touched by mistake, and the baffle 230 can also play a role in protecting the button 300 from corrosion to a certain extent. Of course, in other embodiments, a sliding rail may be added to the enclosure 100, and the baffle 230 may be disposed on the sliding rail, so as to achieve the effect of opening or closing the enclosure 100 by moving on the sliding rail.

In addition, in the present embodiment, the surface of the packaging box 100 is further provided with a through hole 130 for threading, and the button 300 in the packaging box 100 is electrically connected with the circuit outside the packaging box 100 through the through hole 130, so that the button 300 can play a role in controlling the EMO circuit.

In this embodiment, the through hole 130 is generally required to be disposed in the area where the receiving area is located, and since a certain partition is formed between the receiving area and the mounting area by the fixing plate 200, the effect of corroding the button 300 in the mounting area by the through hole 130 with corrosive gas can be reduced or even eliminated by disposing the through hole 130 in the receiving area; in addition, in the actual production process, the through holes 130 are generally subjected to sealing treatment, so that the occurrence of the condition that corrosive gas enters the package box 100 through the through holes 130 can be reduced to the greatest extent.

In addition, in the actual operation process, the space of the accommodating area is generally larger than that of the mounting area, so that some circuits or electronic elements can be placed in the accommodating area, so that the button 300 can be electrically connected with the external circuit; but also the emergency button device 001 may be provided with some special functions by electronic components, for example, the button 300 may be provided with an automatic power-off function by placing a temperature sensor or a humidity sensor or the like.

The present embodiment also provides a chemical delivery apparatus (not shown), which includes a control panel and the emergency button device 001, and the button 300 is electrically connected to the control panel; the button 300 in the chemical delivery apparatus is not easily corroded, so that the circuit between the button 300 and the control panel is not easily disabled, and the chemical delivery apparatus is not easily subjected to safety accidents.

The above embodiments of the present utility model are only examples, and are not intended to limit the scope of the present utility model, and various modifications and variations will be apparent to those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model should be included in the protection scope of the present utility model.
