(3), roller shutter case flexural strength is not enough.

Summary of the invention

In view of this, the utility model provides a kind of novel roller shutter casing structure, to overcome deficiencies such as the installation that exists in the existing roller shutter case, maintenance, sealing.

Therefore, the utility model provides the roller shutter casing structure, includes upper encloser, lower encioser, and it focuses on: this upper encloser is provided with the hook groove in the termination on one side, this lower encioser is provided with the single bending that cooperatively interacts with this hook groove in the termination on one side, and this upper encloser and lower encioser are combined closely by this hook groove and single bending.

In addition, the side, cross section of this upper encloser is a right-angle structure, and flanging is established in the another side termination relative with the termination, one side that is provided with the hook groove; Flanging is established in the another side termination that this lower encioser is relative with the termination, one side that is provided with single bending.

The side, cross section of this lower encioser is to form right-angle structure through twice flanging.

The termination, one side that this upper encloser is provided with the hook groove is the orthodrome structure.

This side, lower encioser cross section is an arc structure.

Roller shutter case good seal performance provided by the utility model, particularly it has following beneficial effect:

1, its upper encloser and lower encioser joint designs by being provided with on this shroud body, thus make between the upper and lower case of roller shutter and to connect and form whole casing structure, make the roller shutter case can realize suitability for industrialized production, produce, install, construction is convenient;

2, this lower encioser on one side the termination single bending and upper encloser on one side the case that cooperatively interacts of the hook groove that is provided with of termination design, make the better tightness of roller blind system, outward appearance is more beautiful;

3, this upper and lower case is provided with the anti-bending strength that flanging increases case;

4, upper and lower case joint designs constructs, safeguards convenient.

The specific embodiment

For the clear structure of the present utility model of your auditor is formed, and the overall operation mode, cooperate graphic being described as follows now:

The utility model roller shutter casing structure 1, as shown in Figure 1 and Figure 2, it includes upper encloser 2, lower encioser 3, it focuses on: this upper encloser 2 is provided with hook groove 4 in the termination on one side, this lower encioser 3 is provided with the single bending 5 that cooperatively interacts with this hook groove 4 in the termination on one side, and this upper encloser 2 is crossed this hook groove 4 with lower encioser logical 3 and combined closely with single bending 5.By the combine closely effect of hook groove 4 with single bending 5, can make the good airproof performance of roller shutter casing structure, outward appearance is more attractive in appearance, reaches good waterproof effect, and the structure that its upper and lower case is connected can realize suitability for industrialized production, and it is convenient to produce, install, construct.

As Fig. 1-shown in Figure 8, be the utility model first specific embodiment.

The side, cross section of this upper encloser 2 is a right-angle structure, and flanging 6 is established in the another side termination relative with the termination, one side that is provided with hook groove 4; Flanging 7 is established in the another side termination that this lower encioser 3 is relative with the termination, one side that is provided with single bending 5.Utilize the structure design of this flanging 6,7 and single bending 5 and hook groove 4, can increase the anti-bending strength of case integral body.The side, cross section of this lower encioser 3 is to form right-angle structure through twice flanging.Like this, both formed the whole square roller shutter casing structure that is.

The design of the square casing structure that the single bending 5 of the lower encioser 3 of this roller shutter case and the hook groove 4 of upper encloser 2 cooperatively interact, with closely cooperating of left end seat 8 and plastics contiguous block 10, steel joint tongue 11 and right end base 9, make the better tightness of roller blind system, as Fig. 7, shown in Figure 8.

As Fig. 9-shown in Figure 16, be the utility model second specific embodiment.

The side, cross section of this upper encloser 2 is similarly right-angle structure, and flanging 6 is established in the another side termination relative with the termination, one side that is provided with hook groove 4; Flanging 7 is established in the another side termination that this lower encioser 3 is relative with the termination, one side that is provided with single bending 5.Utilize the structure design of this flanging 6,7 and single bending 5 and hook groove 4, can increase the anti-bending strength of case integral body.In addition, the termination, one side that this upper encloser 2 is provided with the hook groove is orthodrome 12 structures, and this side, lower encioser 3 cross section is an arc structure.After upper and lower case 2,3 is combined closely, both formed the whole circular roller shutter casing structure that is.

The design of the circular enclosure shell structure that single bending 5 of the lower encioser 3 of this roller shutter case and the hook groove 4 of upper encloser 2 cooperatively interact with closely cooperating of left end seat 8 and right end base 9, makes the better tightness of roller blind system, as Figure 15, shown in Figure 16.

Above implementation and graphic shown in, being the utility model preferred embodiment, is not to limit to the utility model with this, be with, such as be similar to, duplicate with structure of the present utility model, device, feature etc., all should belong to of the present utility model founding within purpose and the claim.
