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 only for the purpose of explaining the present invention, and should not be construed as limiting the present invention.

Example one

As shown in the attached drawings 1-5, the embodiment provides a household CO alarm convenient to mount, which comprises an alarm body 1 and a base in threaded connection with the alarm body 1, wherein the base comprises a tubular shell 2, one end of the shell 2 is an open end, and the other end of the shell is a closed end; be equipped with suction tube 3 in the casing 2, suction tube 3's one end and casing 2's inner wall looks sealing connection, and suction tube 3's the other end is the open end, and 3 outer walls of suction tube of open end and casing 2 looks sealing connection.

The suction tube 3 is internally provided with a piston 4, the piston 4 is attached to the inner wall of the suction tube 3 and can slide along the suction tube 3, the bottom of the piston 4 is fixedly connected with a plug 5, and a pull rod 7 is arranged below the plug 5 and is connected with the plug 5. The pull rod 7 extends to the outer side of the shell 2 and is communicated with the outside, the outer wall of the pull rod 7 is provided with a limiting rod 8, the inner wall of the suction tube 3 is provided with a sliding groove 302, and the limiting rod 8 is arranged in the sliding groove 302 in a sliding manner.

The outer wall of the shell 2 is also provided with a plurality of suckers 11, so that the adsorption force with the installation wall surface can be improved; the upper end of the suction tube 3 is also provided with an air inlet 301; the air inlet hole 301 is communicated with a gas collecting pipe 10, the gas collecting pipe 10 is arranged in the shell 2 and fixedly connected to the inner wall of the shell 2, and the gas collecting pipe 10 is communicated with the sucker 11.

The base is arranged and the sucker 11 is arranged on the base, so that the base is adsorbed on the installation surface in a punching-free mode, no tool is needed, the installation is rapid and convenient, and the base can be used repeatedly; in addition, through setting up suction tube 3, utilize suction tube 3 to extract gas and produce the negative pressure, realize the base and adsorb firmly on the installation face, improve the stability of whole device.

In order to facilitate taking down alarm body 1 for maintenance, alarm body 1 upper end is equipped with external screw thread 101, and casing 2 is equipped with on the open end inner wall with external screw thread 101 assorted internal thread 201, through threaded connection, makes things convenient for the dismouting.

In order to facilitate pulling the pull rod 7, a handle 9 is fixedly connected to the bottom of the pull rod 7.

The specific using process is as follows:

when the device is used, the sucker 11 on the base is attached to the installation wall surface, and gas in the sucker 11 enters the suction tube 3 through the gas collecting pipe 10, so that the primary fixation of the sucker 11 and the installation wall surface is realized; then, the handle 9 is pulled downwards, the handle 9 drives the pull rod 7 to move downwards, and further the piston 4 moves downwards, and the suction tube 3 is communicated with the gas collecting tube 10 and the sucker 11, so that gas in the gas collecting tube 10 and the sucker 11 can be extracted, negative pressure is formed in the sucker 11, and the base can be firmly adsorbed on an installation wall surface, and the stable arrangement of the base is realized; along with the continuous lapse of piston 4, gag lever post 8 moves down in spout 302, and when 8 roll-off spouts 302 of gag lever post, twist grip 9 made 8 joints of gag lever post in the terminal surface department of suction tube 3, has just so realized the location of piston 4, makes sucking disc 11 keep firmly adsorbed state always, has realized that the base is fixed on the installation wall, then passes through threaded connection on the base with alarm body 1, realizes the installation of whole device, easy operation, swift.

Example two

As shown in fig. 6, the present embodiment provides a household CO alarm device convenient to install, and other structures are the same as those of the first embodiment, except that in the present embodiment, a plug 5 is fixedly connected to the bottom of a piston 4, a bearing 6 is connected to the bottom of the plug 5, a pull rod 7 is arranged below the bearing 6 and connected to the bearing 6, and the pull rod 7 extends to the outside of a housing 2 to communicate with the outside. Through setting up bearing 6, when rotating pull rod 7, can realize that plunger 5 and piston 4 do not follow-up with pull rod 7, the aim at that sets up like this: because the friction force between the piston 4 and the inner wall of the suction tube 3 is larger, the pull rod 7 can be conveniently rotated, and the operation is simple and labor-saving.

The utility model discloses a mode of exempting from to punch adsorbs the base on the installation wall, does not need any instrument help, simple structure, reasonable in design, installation are swift, simple and convenient. The problem of current CO alarm installation very loaded down with trivial details effectively is solved, and because the artifical installation that punches during the installation, the instrument that needs the preparation is more, not only wastes time and energy, and installation cost is high moreover, also is inconvenient to be dismantled.
