Abstract

The utility model relates to a door fixing device, in particular to a door staying device, which has a stay (1), and the stay (11) comprises a first stay (11), a second stay (12) and a connector (2), wherein the first stay and the second stay are long strip-shaped parts of the same structure and configuration; a through hole is arranged on the surface of one end of each stay, and a concave fan-shaped oblique step (102) is arranged on the surface of the other end, vertical surface of which is an internal inclined plane inclining towards lower edge of the stay, and a connecting shaft hole (103) is arranged on the step surface. The first stay and the second stay are positioned in a face-to-face stack via step surfaces of the oblique steps to make the connecting shaft holes have the same axial line and then hinged together via the connector. The utility model can effectively fix a door and has the advantages of simple operation and long service life.

Description

The portal bracing blocking means

Technical field

The utility model relates to a kind of fastening devices, relates in particular to a kind of portal bracing blocking means.

Background technology

Cupboard door practical on some vehicles or door when opening owing to transport facility in motion speed change to produce and rock, close automatically easily.If have personnel to stand in front of the door, then come to harm easily.In order to prevent that door from rocking, need personnel to buttress door on the other hand, very inconvenient.Begin to adopt some locating parts in order to address the above problem people, energy control gate opening angle, but the effect that does not reach fixed gate; Some fixtures are also arranged, as be installed in the spacer between door and the doorframe, but operation inconvenience, itself intensity is low, damages easily, and customer responsiveness is very strong.

Summary of the invention

The utility model is intended to solve existing portal bracing retaining operation inconvenience, the easy defective of damaging, and a kind of portal bracing blocking means is provided.The utility model portal bracing blocking means is fixed gate effectively, and easy and simple to handle, long service life.

A kind of portal bracing blocking means, comprise spacer, described spacer comprises first spacer, second spacer and a connection piece, first spacer and second spacer are the elongated member that has with spline structure and configuration, have through hole on one the surface of each spacer, the surface, other end is provided with a recessed fan-shaped oblique step, the vertical plane of described oblique step is the interior inclined-plane that tilts towards the spacer lower limb, the terrace of step is provided with one and connects axis hole, described first spacer and second spacer are superimposed relatively and make and be connected axis hole on same axis by the terrace of oblique step, and be hinged by connector then.

The step thicknesses of described first spacer and second spacer respectively is half of itself thickness.

Described connector is a rivet, and two spacers can rotate around it; The through hole of first spacer and second spacer is equipped with respectively they is connected to screw on a top and the doorframe separately.

For strengthening stoping counter-rotating of the present utility model, it also comprises a torsion spring, have pore on the surface of the close described through hole of described first spacer and second spacer, described torsion spring one end is fixed in the pore of second spacer, and the other end is connected on the fixing screw of second spacer and door top.

Described first spacer and second spacer contract after the side that is connected to each other a side is, the axis hole on the described oblique step be centered close to each spacer after the lateral location that contracts, its outside end face is a circular arc, its diameter is less than the spacer width.

When the utility model has mainly utilized two spacers to rotate greater than 180 ° by a run-on point, form a dead point, be difficult for counter-rotating, and the angle that the shape by spacer reaches between two spacers is slightly larger than 180 °, make two spacers can't continue just to change, two spacers are fixed in this position.This device is installed between casing and the door, just can plays fixing after the unlatching, when closing, push away between two spacers gently, make angle between two spacers less than 180 °, two spacers just can reverse, door is closed, thereby solved the automatic closing problem of door.

Description of drawings

Below, provide the specific embodiment of the present utility model in conjunction with the accompanying drawings:

Fig. 1 is a front view of the present utility model;

Fig. 2 is an A-A sectional view among Fig. 1;

Fig. 3 is described spacer front view;

Fig. 4 is a B-B sectional view among Fig. 3;

Fig. 5 is an I part partial enlarged drawing among Fig. 3;

The specific embodiment

Extremely shown in Figure 5 as Fig. 1: a kind of portal bracing blocking means, comprise spacer 1, described spacer 1 comprises first spacer 11, second spacer 12 and a connection piece 2, first spacer 11 and second spacer 12 are the elongated member that have with spline structure and configuration, have through hole on one the surface of each spacer, the surface, other end is provided with a recessed fan-shaped oblique step 102, the vertical plane of described oblique step 102 is the interior inclined-planes towards the lower limb inclination of spacer 1, the terrace of step 102 is provided with one and connects axis hole 103, described first spacer 11 and second spacer 12 are superimposed relatively and make and be connected axis hole 103 on same axis by the terrace of oblique step 102, and be hinged by connector 2 then.

As seen from Figure 4, the step 102 thickness δ of first spacer 11 and second spacer 12 are half of itself thickness deltat, i.e. Δ=2 δ.

Described connector 2 is a rivet, and two

spacers

11,12 can rotate around it; The through hole of first spacer 11 and second spacer 12 is equipped with respectively they is connected to

screw

31,32 on a top and the doorframe separately.

For strengthening stoping counter-rotating of the present utility model, it also comprises a torsion spring 4, have pore 104 on the surface of the close described through hole of described first spacer 11 and second spacer 12, described torsion spring 4 one ends are fixed in the pore 104 of second spacer 12, and the other end is connected on the fixing screw 32 of second spacer 12 and door top.

Described first spacer 11 and second spacer 12 contract behind the side 105 that is connected to each other a side, connection axis hole 103 on the described oblique step 102 be centered close to each spacer after side 105 positions of contracting, its outside end face is a circular arc, and diameter phi is about 80% of spacer width.

In preferred forms of the present utility model, consider outward appearance, two

spacers

11,12 adopt stainless steel polishing to make, and scribble lubricant grease on the terrace of two interconnected oblique steps 102, and its dimension precision requirement are higher.
