CN202030139U - Separable cover - Google Patents

Abstract

The utility model relates to the technical field of separation structure and specifically discloses a separable cover. The separable cover comprises a cover plate and an annular flange which extends to a certain distance from the cover plate. The cover plate and the annular flange form a plate-shaped structure. The cover plate forms a projection on the surface of the flange relative to the annular flange. The cover plate can be of a round shape, an oval shape, a square shape or other shapes. A plurality of mounting through holes are uniformly arranged on the annular flange, and cut-out grooves are disposed between the mounting through holes and the outer rim of the annular flange. The cover can be rapidly mounted and rapidly separated, is reliable for connection and separation, can bear loads from outer pressure and resist vibration, shaft compression and other loading situations. And the cover is suitable for housings with different curved surfaces, different shapes and different thicknesses, and has the advantages of easy principle, simple structure, light weight, and convenience for processing and dismounting.

Description

A kind of detachable flap

Technical field

The utility model relates to the isolating construction technical field, is specifically related to a kind of detachable flap.

Background technology

In the modern life, be similar to needs such as automobile, train, steamer use have interim linkage function but under certain load the port cover structure of reliable separation local innumerable, and they need to use modes such as mechanical connection such as fastener or splicing to satisfy the requirement of aspect such as connection.When flap decomposes or needing the people be that the place to go fastener is whole decomposes, or adopt monolateral hinge to connect tripartite in addition artificial decomposition.Decompose and artificially to realize though this port cover structure connects reliable; Can not under certain load, decompose voluntarily by failure-free; If will realize decomposing voluntarily need design organization or controllable function parts; Particularly, require to keep under certain load connecting on the specialities, the flap that decomposes voluntarily under another horizontal load, and former common port cover structure can not satisfy above-mentioned requirements.

Summary of the invention

The purpose of this utility model is to provide a kind of satisfy difformity, the requirement of different-thickness housing, installs fast, connects reliable, separation failure-free port cover structure.

The technical solution of the utility model is as follows: a kind of detachable flap, comprise cover plate and outside cover plate, extend an end distance from the hoop flange, on the hoop flange, rectangular distribution N through hole is installed, and between each installation through hole and hoop flange outer rim, is had the cut-out groove.

Described cover plate can be circular, oval, square or other shapes.

Described cover plate forms projection with respect to the hoop flange on the direction of a face.

Described installation through hole number N is between 3 to 6.

The typical number of described installation through hole is 4.

Remarkable result of the present utility model is: detachable flap described in the utility model, can Fast Installation, separate fast, connect reliably, separate reliably, can bear outer compressive load, load environment such as vibration resistance and axial compression, the housing that can adapt to different curve, difformity, different-thickness uses, and principle is simple, simple structure, in light weight, easy processing, easy to assemble.

Description of drawings

Fig. 1 is a detachable port cover structure scheme drawing described in the utility model;

Fig. 2 is a separation type flap lateral plan among Fig. 1;

Among the figure: 1, cover plate; 2, hoop flange; 3, through hole is installed; 4, cut off groove.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is described in further detail.

As shown in Figure 1 and Figure 2, the hoop flange 2 that detachable flap comprises cover plate 1 and extend a segment distance outside cover plate 1, cover plate 1 and the hoop flange 2 whole platy structures that form, and cover plate 1 forms projection with respect to hoop flange 2 on the direction of a face, wherein, cover plate 1 can be circular, oval, square or other shapes, its with the housing that detachable flap is installed on detachable flap is installed barbed portion be complementary; On hoop flange 2, rectangular distribution N through hole 3 is installed, and between each installation through hole 3 and hoop flange 2 outer rims, is had cut-out groove 4, wherein, 3≤N≤6.

The principle of work of detachable flap described in the utility model is: tightening screw passes installation through hole 3 detachable flap is fixed on the housing of detachable flap to be installed, and the projection of assurance cover plate 1 is over against enclosure interior.The device that detachable flap is installed bears external load in the outside of separable flap; to arrive protection the purpose of separable flap device inner structure is installed; separate at needs under the situation of detachable flap; internal load applies internal pressure to cover plate 1; make and produce tangential pulling force between hoop flange 2 on the detachable flap and the tightening screw; cut off groove 4 and weaken the effect of hoop flange 2 local strengths; hoop flange 2 is torn from cutting off groove 4 under the effect of tangential pulling force; be that tightening screw withdraws from hoop flange 2 scopes by connecting through hole 3, reach the purpose of flap overall separation.

Claims (5)
