Abstract

The utility model relates to an anti -collision fire hydrant, it includes key, valve body and valve rod, the key is including burying lower key underground, the last key that bassets, the valve body sets up in key down, and the valve body passes through the valve rod and is connected with the switch of setting on last key, the valve rod is including setting up under the lower valve rod in the key of upper valve rod in last key, setting, go up the key and connect through security bolt between the key down, through profile of tooth clutch between upper valve rod and the lower valve rod. The utility model discloses be divided into relatively independent upper and lower two parts on the key, both pass through security bolt fixed connection, and when upper portion received the impact, security bolt's annular groove at first split for upper and lower key natural separation, and go up the lower valve rod and separate in succession yet can not result in the valve body impaired from this, and then can not cause that the running water reveals, the utility model discloses simple structure, convenient to use even receive the striking back, still can continue to use through changing the bolt.

Description

Anti-collision fire hydrant

Technical field

This utility model relates to a kind of Anti-collision fire hydrant.

Background technology

The fire hydrant being located at road both sides is used to facilitate fire fighting truck moisturizing, but is often subject to car Shock and lost efficacy, cause tap water to run off in a large number.Excavation and replacing work are wasted time and energy, Not only break up environment and make troubles to surrounding resident.Although being desirable that now that fire hydrant has Crashproof function, but it is to be directly embedded in underground mostly due to lower body, the most solid Determine mode, when clashing into the key on top, it is difficult to ensure that valve body is not moved, although alleviate Impact Problems, but need nonetheless remain for certain maintenance work.

Utility model content

In place of the purpose of this utility model is to avoid the deficiencies in the prior art, it is provided that a kind of crashproof Fire hydrant, thus in place of effectively solving the deficiencies in the prior art.

For achieving the above object, the technical scheme that this utility model is taked is: Anti-collision fire hydrant, its Including key, valve body and valve rod, key include being embedded in underground lower bolt, basset upper Key；Valve body is arranged in lower bolt, and valve body passes through valve rod and the switch being arranged on upper bolt Connect；Valve rod includes the upper valve rod being arranged in upper bolt, the lower valve rod being arranged in lower bolt； Connected by breaker bolt between upper bolt and lower bolt；Tooth is passed through between upper valve rod and lower valve rod Shape clutch connects.

Further, described breaker bolt includes screw rod, and screw rod docks at described upper and lower key Corresponding position is provided with annular groove.

Further, being provided with upper flange bottom described upper bolt, the top of described lower bolt is arranged Lower flange；By upper and lower flange, upper and lower key links together；Lower flange diameter is more than Upper flange 10-20mm.

Technique scheme of the present utility model has the advantages that this utility model key On be divided into relatively independent two parts up and down, both connect by breaker bolt is fixing, work as top When being impacted, first the annular groove of breaker bolt ruptures so that upper lower bolt natural separation, And upper lower valve rod separates the most in succession, impaired thus without causing valve body, and then will not cause from the beginning Water is revealed, and this utility model simple in construction is easy to use, even if after being clashed into, by more Change bolt to may continue to use.

Detailed description of the invention

Make to retouch the most in detail to embodiment of the present utility model with embodiment below in conjunction with the accompanying drawings State.Following example are used for illustrating this utility model, but can not be of the present utility model for limiting Scope.

In description of the present utility model, except as otherwise noted, " multiple " be meant that two or Two or more；Term " on ", D score, "left", "right", " interior ", " outward ", " front end ", " after End ", " head ", the orientation of the instruction such as " afterbody " or position relationship be based on side shown in the drawings Position or position relationship, be for only for ease of description this utility model and simplify description rather than refer to Show or imply that the device of indication or element must have specific orientation, with specific azimuth configuration And operation, therefore it is not intended that to restriction of the present utility model.In description of the present utility model In, it should be noted that unless otherwise clearly defined and limited, term " is connected ", " even Connect " should be interpreted broadly, connect for example, it may be fixing, it is also possible to be to removably connect, Or be integrally connected；Can be to be mechanically connected, it is also possible to be electrical connection；Can be to be joined directly together, Can also be indirectly connected to by intermediary.For the ordinary skill in the art, may be used Above-mentioned term concrete meaning in this utility model is understood with concrete condition.

As Figure 1-3, the Anti-collision fire hydrant described in the present embodiment, it includes key 1, valve body 2 and valve rod 3, key 1 includes the lower bolt 1b being embedded in underground, the upper bolt basseted 1a；Valve body 2 is arranged in lower bolt 1b, and valve body 2 passes through valve rod 3 and is arranged on upper bolt Switch on 1a connects；Valve rod 3 includes the upper valve rod 3a being arranged in upper bolt, is arranged on Lower valve rod 3b in lower bolt；By breaker bolt 6 between upper bolt 1a and lower bolt 1b Connect；It is connected by gear clutch 4 between upper valve rod 3a with lower valve rod 3b.

Breaker bolt 6 is made up of standard bolt, and it includes screw rod, and screw rod is described upper and lower The corresponding position of key docking is provided with annular groove 6a.

And bottom upper bolt 1a, it being provided with upper flange 1a1, the top of lower bolt 1b is arranged down Flange 1b1；By upper and lower flange, upper and lower key links together；Lower flange diameter More than upper flange 10-20mm.When the mounting means of lower flange is for being arranged on ground, purgation Blue bottom is provided with lower convex edge, and lower convex edge can be the annular that border is closed, it is also possible to be disconnected Continuous annular, head can be that right angle can also be for acute angle.

Embodiment of the present utility model is given for the sake of example and description, and is not Exhaustively or by this utility model it is limited to disclosed form.Many modifications and variations for It is apparent from for those of ordinary skill in the art.Select and describe embodiment be in order to Principle of the present utility model and actual application are more preferably described, and make the ordinary skill people of this area Member is it will be appreciated that this utility model thus design are suitable to various with various amendments of special-purpose Embodiment.
