[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0024] As Figures 1-5 shown, it relates to a fire hydrant button with a protective cover, including a fire hydrant button body 1. An annular plate 3 is fixed on the surface of the fire hydrant button body 1 close to its button piece side. A protective shell 4 is fixedly sleeved on the surface of the annular plate 3. A fixed cylinder 5 is fixed in the middle of the protective shell 4. A perforation 51 is opened in the middle of the end of the fixed cylinder 5 away from the protective shell 4, and an extrusion assembly 6 is arranged inside the perforation 51. An end cap 7 is slidably sleeved on the surface of the fixed cylinder 5. The extrusion assembly 6 can be pushed to move through the end cap 7. Horizontal grooves 52 and vertical grooves 53 are opened on the side wall of the fixed cylinder 5, and the horizontal grooves 52 and the vertical grooves 53 are communicated. A slide block 71 is fixed on the inner wall of the end cap 7, and the slide block 71 can slide along the horizontal grooves 52 and the vertical grooves 53. A through hole 72 is opened on the side wall of the end cap 7 and opposite to the slide block 71, and a locking assembly 8 for fixing the end cap 7 is arranged inside the through hole 72.

[0025] A plurality of mounting plates 2 are fixed on the side of the fire hydrant button body 1.

[0026] The fire hydrant button body 1 can be fixedly installed through the mounting plates 2.

[0027] The protective shell 4 and the annular plate 3 are fixedly connected by bolts.

[0028] Therefore, the protective shell 4 can be disassembled from the surface of the annular plate 3, so as to facilitate the overall replacement of the protective shell 4 and the components on the protective shell 4.

[0029] The horizontal groove 52 and the vertical groove 53 are perpendicular to each other, and an indication mark is arranged on the surface of the end cap 7.

[0030] The usage method of rotating the end cap 7 can be known through the indication signs. Rotate the end cap 7 along the surface of the fixed cylinder 5 so that the slider 71 slides from the horizontal groove 52 to the end of the vertical groove 53 before the end cap 7 can be pushed to move along the vertical groove 53, and then the extrusion assembly 6 can be pushed by the end cap 7.

[0031] The extrusion assembly 6 includes a spring 61 fixedly connected to the surface of the fixed cylinder 5. The other end of the spring 61 is fixedly connected to an end plate 62. A push rod 63 is fixed on one side of the end plate 62 close to the fixed cylinder 5. The push rod 63 passes through the through hole 51 and extends into the protective shell 4. The end plate 62 fits against the inner wall of the end cap 7.

[0032] Since the end plate 62 and the end cap 7 are only in contact by fitting, it will not affect the rotation of the end cap 7. When the end cap 7 moves along the direction of the vertical groove 53, the end cap 7 will push the end plate 62 and the push rod 63 to move, so as to press the pressing piece of the fire hydrant button body 1 by using the push rod 63.

[0033] The locking assembly 8 includes a clamping rod 81 passing through the through hole 72 and slidably connected to the through hole 72. One end of the clamping rod 81 outside the end cap 7 is fixedly connected to a pull ring 82, and a tension spring 83 is fixedly connected between the pull ring 82 and the outer side wall of the end cap 7. A clamping hole 54 for clamping the clamping rod 81 is formed on the surface of the fixed cylinder 5, and when the clamping rod 81 is clamped into the clamping hole 54, the slider 71 is located inside the horizontal groove 52.

[0034] By pulling the pull ring 82 with the tension spring 83, the clamping rod 81 can be clamped into the clamping hole 54. And since the slider 71 is located inside the horizontal groove 52 when the clamping rod 81 is clamped into the clamping hole 54, the end cap 7 can only be rotated along the horizontal groove 52 after pulling the pull ring 82 to disengage the clamping rod 81 from the clamping hole 54.

[0035] A transparent window 9 is fixed on the top of the protective shell 4. Through the transparent window 9, the pressing condition of the pressing piece of the fire hydrant button body 1 can be observed.

[0036] Working principle: When it is necessary to press the pressing piece of the fire hydrant button body 1, first pull the pull ring 82 to disengage the clamping rod 81 from the clamping hole 54 on the surface of the fixed cylinder 5, and then rotate the end cap 7 with the other hand. When the slider 71 on the inner wall of the end cap 7 rotates from the horizontal groove 52 to the vertical groove 53, press the end cap 7 along the surface of the fixed cylinder 5, and use the end cap 7 to squeeze the end plate 62 and the push rod 63, and press the pressing piece of the fire hydrant button body 1 through the push rod 63.

[0037] The preferred embodiments of the present utility model disclosed above are only used to help illustrate the present utility model.
