The base further comprises a U-shaped end cover, the shape of the U-shaped end cover is matched with the space of the side face of the base body in an inserted and sealed mode, and the L-shaped blocking wall is located in a separation groove of the U-shaped end cover. Pressing strips are arranged on the rear portions of the two inner walls of the separation groove, and guide faces are machined on the front portions of the pressing strips. The pressing strips are used for extruding the L-shaped blocking walls inwards. The ceiling screen has the advantages that the ceiling screen is convenient to install, the ceiling screen is tightly installed and does not shake relatively, and smoke leakage is greatly reduced.

Description

Technical Field

[0001] This utility model relates to the field of smoke curtain technology, and in particular to a tight-fitting smoke curtain base. Background Technology

[0002] Existing smoke curtain bases are generally T-shaped, with two spaced L-shaped baffles at the top. After the smoke curtain is inserted into the two L-shaped baffles or slids in from the side, it is blocked by the two L-shaped baffles by the blocks clamped at both ends of the bottom of the smoke curtain, thus preventing it from detaching from the base.

[0003] However, existing smoke curtain bases have some problems. If the gap between the two L-shaped baffles is too small, it affects installation; if it is too large, it affects the tightness of their fit, which not only easily leads to serious smoke leakage, but also causes relative swaying during raising and lowering. To address this, we designed a tight-fitting smoke curtain base assembly. Utility Model Content

[0004] In view of the problems existing in the prior art, this utility model provides a tight-fitting smoke curtain base, which aims to solve the problems of installation and tightness between the existing smoke curtain base and the smoke curtain.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows: a tight-fitting smoke curtain base, comprising a T-shaped base body, wherein two spaced L-shaped baffles are formed at the upper end of the base body; and a U-shaped end cap, wherein the shape of the U-shaped end cap is inserted and sealed with the side space of the base body, and the L-shaped baffles are located in the partition groove of the U-shaped end cap; pressure strips are provided at the rear of the two inner walls of the partition groove, and a guide surface is machined at the front of the pressure strips; the pressure strips are used to press the L-shaped baffles inward.

[0006] Preferably, the upper parts of the two side walls of the base body are inclined inward, and the upper parts of the two side walls of the U-shaped end cap are inclined inward.

[0007] Preferably, the back of the U-shaped end cap is integrally provided with a back plate, which can be used to block gaps and prevent smoke from escaping, making it easy to pick up and install.

[0008] Preferably, the base body and the U-shaped end cap are designed with rounded corners.

[0009] Preferably, the U-shaped end cap has a groove on the front and is provided with reinforcing ribs.

[0010] The advantages of this invention are: it facilitates the installation of the smoke curtain, ensures a tight fit without relative wobbling, and significantly reduces smoke leakage. Attached Figure Description

[0011] Figure 1 This is a schematic diagram of the structure of this utility model. Detailed Implementation

[0012] like Figure 1 As shown, a tight-fitting smoke curtain base includes a T-shaped base body 1, with two spaced L-shaped baffles 11 formed at the upper end of the base body 1; it also includes a U-shaped end cap 2, the shape of which is inserted and sealed into the side space of the base body 1, and the L-shaped baffles 11 are located within the partition groove 21 of the U-shaped end cap 2; each of the two inner walls of the partition groove 21 is provided with a pressure strip 22, and the front of the pressure strip 22 is machined with a guide surface; the pressure strip 22 is used to press the L-shaped baffles 11 inward. The back of the U-shaped end cap 2 is integrally provided with a back plate 23, which can be used to block gaps and prevent smoke from escaping, even when it is easy to remove and install.

[0013] This invention allows the two spaced L-shaped baffles 11 to maintain a large gap, facilitating the insertion of the smoke curtain during use. Then, the upper part of the base body 1 is pinched to reduce the gap. After the U-shaped end cap 2 is inserted, the two spaced L-shaped baffles 11 pass through the two inner walls of the partition groove 21 to the pressure strip 22 with the guide surface. Due to the presence of the two pressure strips 22, after the U-shaped end cap 2 is closed and the two L-shaped baffles 11 are inserted into the partition groove 21, the pressure strips 22 on both sides further compress the two L-shaped baffles 11. After the hand is released, the smoke curtain and the base body 1 are still tightly installed.

[0014] The upper parts of the two side walls of the base body 1 are inclined inward, and the upper parts of the two side walls of the U-shaped end cap 2 are inclined inward; this makes it easy to pinch.

[0015] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions or improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
