Embodiment 1

[0025] Example 1. The electric roller blind powered by a micro motor has an outer casing, and its left and right ends have end covers. Figure 1a The one shown is already a roller blind product. Since the roller blind needs to be placed on the upper edge of the window at a higher place, how to fix it and ensure the safety of the product and the safety of the ground personnel is a problem that must be carefully faced in the installation process of the roller blind product.

[0026] according to Figure 3a The left and right L brackets are constructed as shown in -b, which are suitable for carbon steel stamping parts with good rigidity and load-bearing capacity. The main board (11) of the L holder is equipped with a middle hole (111) and the horizontal hole (112) below which plays a secondary guarantee effect, and the left and right L holders can be placed on the window by means of the middle hole (111) and the horizontal hole (112). The elevation of the upper wall is fixed at...

Embodiment 2

[0032] Example 2. see Figure 8a , such as changing the structure of the above-mentioned left and right end cover concave areas (21) to an external convex dam (22) structure, the working principle of this design device that achieves the preset application purpose can be found in Figure 8b -c, where Figure 8b It shows that the nut C (5) forcibly suppresses the outer convex dam (22) of the end cover (that is, the whole roller blind product), Figure 8c Shown is the non-working unlocked state of the design device. Specifically, the nut C (5) has no obstacles at all to take out the product from the L support (or place the product downward, see the arrow in the figure).

[0033] The rest are the same as embodiment 1.

[0034] It is also worth noting that:

[0035]The cooperation between the screw hole A (141) and the nut B (4) carried on the L support end vertical plate (14) is more conducive to the stability and stability of the bolt (3). The above device can still be appli...

Abstract

The invention discloses a mounting and fixing device for a classroom roller shutter. The mounting and fixing device comprises a left end L-shaped support and a right end L-shaped support which are fixed to the vertical face of a wall at equal height and used for lifting the roller shutter, screw holes A are formed in vertical plates at the outer side ends of the L supports, concave areas are arranged on the end vertical surfaces of a left end cover and a right end cover of the roller shutter housing, bolts penetrate through the screw holes A from outside to inside and then are connected with nuts C, the inner ends of the nuts C are placed in the concave areas of the end covers or separated from the concave areas in the left-right direction, nuts B attached to the L-shaped support end vertical plates facilitate stabilization of the bolts, the proper widths of the left L-shaped support and the right L-shaped support allow a normal operation error to exist in the distance between the left L-shaped support and the right L-shaped support when the wall facade is fixed. According to the mounting and fixing device, the nuts C invade into the concave areas of the end covers to forcibly prevent the product from tripping, so that the personal safety of ground personnel is reliably ensured and the product maintenance requirement is met.

Description

technical field [0001] The invention relates to the installation and fixing of an electric roller blind product on a wall facade, in particular to an installation and fixing device for a classroom roller blind. Background technique [0002] In the quality evaluation of electric roller blinds that emphasize operating noise, with small and micro being excellent, noise prominently affects customer experience, and the requirements for electric roller blinds at the teaching professional level are particularly stringent. Based on the structure and other reasons, generally speaking, the installation of roller blinds should try to avoid the noise caused by the product operation. [0003] Electric roller blinds include micro-motors, steel cages at both ends, long metal roller tubes and curtains, etc., and the product weight is generally at least several kilograms. The roller shutter is located above the window at a height of about 3 meters, and there are usually student seats under ...
