Abstract

The utility model relates to a hydrant case, in particular to a plane chamfer angle of hydrant case frame and a joint design of plane chamfer angle. The hydrant case frame and the plane chamfer angle of joint consist of mutual connection of a plurality of plane chamfer angle frames. The utility model is characterized in that the joint of every plane chamfer angle frame is fixed by mutual insertion of the plane chamfer angles. The plane chamfer angle and the joint of the utility model can not only facilitate the integrated connection of the four edges of the hydrant case frame, but also greatly increase the security of the frame due to the external angle of the joint is a plane chamfer angle; the utility model can also completely eliminate the non-safety factor of the current hydrant base frame.

Description

The plane chamfering and the joint design thereof of fire hydrant box framework

Technical field

The utility model relates to a kind of fire hydrant box, the plane chamfering and the joint design thereof of more specifically saying so and relating to a kind of fire hydrant box framework.

Background technology

The framework of traditional fire hydrant box all is to adopt right angle face section bar directly to connect to make, its moulding dullness, stiff, and also its sharp-pointed corner angle regular meeting causes the insecurity in product uses.

The framework that the purpose of this utility model is fire hydrant box by the planar inverted angle of transformation traditional right angle, novel and beautiful but also be connected with framework quickly and easily not only, and safe and reliable fire hydrant box plane chamfering framework and planar inverted angle joint structure thereof for the unsafe factor of eliminating existing fire hydrant box framework provides a kind of.

Summary of the invention

The purpose of this utility model is achieved by the following technical solution: the planar inverted corner structure of fir-hydrant box framework of the present utility model and joint, interconnect by a plurality of planar inverted arm of angle frames and to form, it is characterized in that per two planar inverted arm of angle frames insert fixing in its junction by the planar inverted angle joint mutually.

Planar inverted angle joint described in the utility model is made of two orthogonal right-angle sides and the drift angle that connects this two right-angle side, and wherein the profile of two orthogonal right-angle sides is corresponding with the interior hole shape of frame, and forms fastening plug-in type with frame and be connected.Two outer side planes of described drift angle are connected with the chamfering plane of its front by 30 °～45 °.The framework and the joint design of the plane chamfering of described fire hydrant box is characterized in that, the intersection on described two chamfering planes is by tiny smooth arc transition.

The framework and the joint design of the plane chamfering of fire hydrant box described in the utility model is characterized in that described drift angle is shaped by plastic production.

As seen from the above technical solution, plane of the present utility model chamfering framework and joint design thereof not only can make the four edges of the framework of fire hydrant box connect into integral body quickly and easily, and because to be chamfering plane the exterior angle of joint, therefore the security of using improves greatly, and has thoroughly eliminated the existing unsafe factor of existing fire hydrant box framework.

Specific embodiment

Below in conjunction with description of drawings the utility model is described in further detail: as shown in Figure 1, structure of the present utility model has comprised planar inverted arm of angle frame 2, and filleted junctions 1 is connected frame 2 by putting down at place, four angles.Consult Fig. 2-Fig. 4, fire hydrant box of the present utility model plane chamfering framework and joint design comprise planar inverted arm of angle frame 2, and two outer side planes of this frame are connected by the plane of 30 ° of-45 ° of chamferings.Main points of the present utility model are that the four edges of frame 2 is connected by planar inverted angle joint 1 at place, four angles, and the shape of plane material angle joint is as Fig. 2--shown in 4.It is made of with the drift angle 12 that is connected two right-angle sides two right-angle sides 11, and wherein the profile of two right-angle sides is corresponding with the interior hole shape of frame, and forms fastening plug-in type with frame and be connected; Two outer side planes of drift angle 12 are connected by 30 °～45 ° chamfering planes with its positive facial plane, and this two chamferings plane in intersection by tiny arc surface transition.After two right-angle sides of joint insert the endoporus of frame, chamfering plane on the joint just with frame on the chamfering plane form consistent chamfering plane, for making joint and frame energy relative fixed after being connected, adopt compaction tool that its fastening-type is pressed into, then framework integral body is locked on the casing of fire hydrant box with screw or pulling rivet.
