A conventional fire- and smoke-proof cabinet with rolling shutters is shown in FIG. 11 and includes: A cabinet 91 configured to be disposed above an access opening (see FIG. 14A). The chassis 91 has a receiving portion 91A, a reel portion 91B, and an opening portion 91C; the reel portion 91B is set up in the receiving portion 91A, and the opening portion 91C is provided with a pair of extension plate members 911 and the pair of extension plate members 911 is extended toward this accommodation portion 91A. A roller blind 92 is wound around the reel portion 91B, and has a first end portion 92A, a second end portion 92B, and a pair of blocking pieces 92C. The first end portion 92A is provided for the roller blind 92 to be wound around the roll shaft portion 91B, and the second end portion 92B is provided for the roller blind 92 to extend out of the opening portion 91C through the pair of extension plates 911. Thereby, when the roller blind 92 is rolled by the rolling shaft portion 91B, it is relatively moved with the pair of extension plates 911. When the roller blind 92 is housed in the accommodating portion 91A, the second end portion 92B of the roller blind 92 is adjacent to the opening portion 91C (see FIG. 12A); when the roller blind 92 is rolled out of the accommodating portion 91A In the process, the second end portion 92B of the roller blind 92 is far from the opening portion 91C, and descends to the ground along a pair of side guides 81 (see FIGS. 12B and 14B) (see FIGS. 15A and 15B). ), The pair of barrier sheets 92C are attached to the pair of extension plates 911 (see FIGS. 12C and 13B), so that the barrier gas cannot flow from one side of the roller shutter 92 to the coil through the receiving portion 91A. The other side of the curtain 92. However, each of the extension plates 911 is bent after being cut out of sheet metal. Therefore, each of the extension plates 911 has at least two sharp angles M resulting from the cutting. When the roller blind 92 or the pair of barrier sheets 92C and the When an extension plate 911 is relatively moved (see FIGS. 13A and 13B), it is extremely easy to be scratched by contacting the acute angle M. In view of this, it is necessary to develop technologies that can solve the above-mentioned conventional disadvantages.

The purpose of the present invention is to provide a fireproof and smokeproof case with a smooth end, which has the advantages of avoiding scratches on the roller blind and the barrier and being easy to implement. In particular, the problem to be solved by the present invention is that the extension plate of the traditional case is cut and bent from sheet metal, and therefore has at least two sharp angles generated by cutting. When the roller shutter or the pair of When the barrier sheet moves relative to any of the extension plates, it is very easy to be scratched due to contact with the acute angle. The technical means for solving the above problems is to provide a fireproof and smokeproof cabinet with a smooth end portion, which includes: a cabinet configured to be arranged above a passage opening; the cabinet has a receiving portion, a reel portion, and an opening And at least one smooth end portion; the reel portion is set in the receiving portion, the opening portion is provided with at least one extension plate, and the at least one smooth end portion is correspondingly provided at the end of the at least one extension plate. A roller blind, which is wound around the reel portion, and has a first end portion and a second end portion; the first end portion is for the roller blind to be wound around the reel portion, and the second end portion is The roller blind is extended through the at least one smooth end portion to extend the opening portion; thereby, when the roller blind is rolled by the scroll shaft portion, the roller blind is moved relative to the at least one smooth end portion to avoid being scratched. The wounded. The above-mentioned objects and advantages of the present invention can be easily understood from the detailed description and accompanying drawings of selected embodiments below. The following examples and drawings are used to explain the present invention in detail:

Referring to Figures 1, 2, 3A, 3B, 4A, and 4B, the present invention is a fireproof and smokeproof case with smooth ends. The first embodiment includes a case 10 and a roller shutter. 20. The chassis 10 is arranged above an access port (see FIG. 14A). The chassis 10 includes a receiving portion 10A, a reel portion 10B, an opening portion 10C, and at least one smooth end portion 10D. The reel portion 10B is mounted in the receiving portion 10A, and the opening portion 10C is provided with at least one extension plate. Piece 11, the at least one smooth end portion 10D is correspondingly disposed at the end of the at least one extending plate piece 11. The roller blind 20 is wound around the reel portion 10B and has a first end portion 20A and a second end portion 20B. The first end portion 20A is used for winding the roller blind 20 around the roller shaft portion 10B, and the second end portion 20B is used for the roller blind 20 to extend through the opening portion 10C through the at least one smooth end portion 10D. Thereby, when the roller blind 20 is rolled by the roller shaft portion 10B, the roller blind 20 is relatively moved with the at least one smooth end portion 10D, so as to avoid being scratched. In practice, the chassis 10 has a plurality of wall members 101, and the receiving portion 10A and the opening portion 10C are interposed between the plurality of wall members 101. That is, when the roller blind 20 is rolled by the roller portion 10B, the roller blind 20 is moved between the at least one smooth end portion 10D and the panel member 101 (plane), so as to avoid being scratched. The at least one smooth end portion 10D is provided with a pair (that is, the second embodiment of the present case, refer to FIGS. 5, 6A, and 6B). A pair of the at least one extension plate 11 is provided (the at least one extension plate 11 extends toward the receiving portion 10A). The at least one smooth end portion 10D group is arranged at a shape corresponding to the end of the at least one extension plate 11, and may be at least one of an integral molding structure and a combined structure. When selected from a one-piece structure, it can be a circular cross-section structure (see Fig. 8A), an elliptical cross-section structure (see Fig. 8B), an arc-shaped cross-section structure, and an arc-shaped bent body structure (see Fig. 8C). Any one of the structures having a smooth arc surface to prevent the roller blind 20 from being scratched. When selected from a combination structure, it can be a sulcus pipe body with a nearly C-shaped cross section (see Figures 6A, 6B, 6C, 7A, 7B, and 7C), and a sulcus with a near U-shaped section. One of the pipe bodies (see FIG. 8D), and is covered on the corresponding end of the extension plate 11. The roller blind 20 further has a blocking portion 20C, which is interposed between the first end portion 20A and the second end portion 20B. Therefore, when the blocking portion 20C contacts the at least one smooth end portion 10D (refer to FIGS. 6A, 6B, 6C, 7A, 7B, and 7C), it is used to block and make one end of the channel opening Gas cannot flow from one side of the roller blind 20 through the receiving portion 10A to the other side of the roller blind 20 (that is, the other end of the passage opening). The barrier portion 20C may be one of a barrier protrusion and at least one barrier. When selected from the barrier projections, it can be an arc cross-section structure, a circular cross-section structure (see Figures 6B and 6C), an oval cross-section structure, an elongated cross-section structure (see Figure 9A), and a member. One of the structure (see FIG. 9B) worn inside the roller blind 20, and any structure that can contact the pair of sliding smooth ends 10D to achieve airtightness. Of course, a thick cloth, metal pipe, hose or any hard object is sewn (fixed) on the roller blind 20 to form the blocking portion 20C, and then close to the (smooth) smooth end portion 10D to achieve gas. The confidential structure does not depart from the scope of protection in this case. When selected from at least one barrier, it may be one of at least one (pair) plate structure, at least one (pair) rod structure, any structure that can be in contact with the at least one (pair) sliding end 10D to achieve airtightness. By. Thereby, when the gas enters the containing portion 10A from between the panel member 101 and the roller blind 20 (refer to FIG. 4A), the barrier is pushed more closely to contact the corresponding smooth end portion 10D to achieve Airtight structure. Of course, the two sides (left and right) of the roller blind 20 are sewn (fixed) with a predetermined length of cloth to form the pair of barriers, and then they can be stuck (or floating), so that when any of the barriers is gas Pushing will push another barrier to contact the corresponding (smooth) smooth end 10D more densely, and achieve an air-tight structure without departing from the scope of protection in this case. The pair of extension plates 11 may be one of relatively parallel (its spacing is just enough for the roller blind 20 to pass), relatively expanded, and relatively tapered, as long as the blocking portion 20C can air-tightly contact the pair of sliding ends. 10D is sufficient. Referring to FIG. 10, the third embodiment of the present case is different from the first embodiment only in that the extension plate 11 extends toward the outside of the chassis 10. The smooth end portion 10D is an integrally formed structure, which is a circular cross-sectional structure. The blocking portion 20C is a barrier, which is one of an arc-shaped plate structure, an arc-shaped rod structure, and any structure that can contact the pair of sliding smooth ends 10D to achieve airtightness. This case is mainly applied to the fire and smoke prevention of the entrance of the building. That is, when one of the two spaces in the building generates a high-temperature gas due to a fire, the fire and dense smoke may spread through the entrance to the other space. At this time, the fire-proof and smoke-proof cabinet with smooth ends is set above the passage opening (see Figures 14A and 14B), and the rolling screen 20 is rolled out to isolate the through opening (see 15A and 15 (Figure 15B), and produces two functions: [a] Anti-scratch function: When the roller blind 20 is rolled by the reel portion 10B, and extends out of the opening portion 10C, it actually slides smoothly with the (pair) end portion The 10D relative movement can be prevented from being scratched because of "smoothing", and the service life of the roller blind 20 can be extended. [b] Smoke prevention function: When the blocking portion 20C contacts the pair of smooth ends 10D (see Figures 6A, 6B, 6C, 7A, 7B, and 7C), it is blocked to make one end of the passage opening The gas cannot flow from one side of the roller blind 20 through the receiving portion 10A to the other side of the roller blind 20 (that is, the other end of the passage opening) to achieve the smoke prevention function. The advantages and effects of the present invention are as follows: [1] It can avoid scratching the roller blind and the barrier. According to the present invention, a smooth end portion is provided at the end of the extension plate of the opening portion of the chassis. When the roller blind is rolled by the reel portion and extends into and out of the opening portion, it actually moves relatively to the smooth end portion. "Smoothing" can avoid being scratched. Similarly, the process of contacting and separating the barrier portion and the smoothing end can also avoid being scratched and prolong the service life. Therefore, it is possible to avoid scratching the roller blind and the barrier. [2] Easy to implement. The present invention merely adds a smooth end to the end of the extension plate. Whether it is an integrally formed structure (direct molding in the manufacturing process) or a combined structure (installation), it is a setting that is easy to implement in related industries. Therefore, it is easy to implement. The above is only a detailed description of the present invention through a preferred embodiment, and any simple modifications and changes made to the embodiment will not depart from the spirit and scope of the present invention.
