Description

Technical Field

[0001] This utility model relates to the field of elevator installation technology, and in particular to a sealing device for elevator door openings. Background Technology

[0002] With the renovation and upgrading of old residential elevators included in the ultra-long-term special treasury bonds, some elevators that have been in use for more than 15 years are gradually entering the process of renovation and upgrading. The demolition of old elevators involves removing the old elevator hall doors, posing a risk of people or foreign objects falling into the elevator shaft. Considering the need for timely sealing of the hall doors after removal, and the need to avoid damaging the door frame surface during sealing, it is not feasible to fix the sealing panel by drilling holes in the door frame, nor is it feasible to fix it by drilling holes in the exterior wall on the same side as the door frame, which would damage the exterior wall tiles. Drilling holes in the elevator shaft to fix the sealing panel would result in an incomplete seal, and the sealing panel, being larger than the elevator hall door, would be impossible to fit into the elevator shaft, making construction difficult. Therefore, there is a need for a sealing device for elevator door openings that achieves the effect of not damaging the elevator door frame and exterior wall surface, and is simple and efficient to construct.

[0027] Example

[0028] Please see Figures 1 to 6This utility model provides an elevator door opening sealing device 100 for sealing elevator hall doors after removal. The elevator door opening sealing device 100 includes two fixed panel modules 1 and a panel 2. The fixed panel module 1 is generally bow-shaped and includes a base 11, a panel fixing member 12, two L-shaped fixing bases 13, and a connecting buckle 14. The base 11 is generally C-shaped and includes a fixing part 111 and connecting parts 112 at both ends of the fixing part 111. The panel fixing member 12 is installed on the side of the fixing part 111 away from the connecting part 112. The connecting part 112 is connected to the L-shaped fixing base 13 through the connecting buckle 14, and the connection position between the connecting part 112 and the L-shaped fixing base 13 is adjustable. The L-shaped fixing base 13 is installed on the door jamb 200 in the elevator shaft, and the panel 2 is installed on the panel fixing member 12 to seal the elevator door opening.

[0029] Preferably, the base 11 is made of metal, and the fixing part 111 and the connecting part 112 are integrally stamped. The fixing part 111 has multiple round holes for screws to be inserted to fix the panel fastener 12.

[0030] For more details, please refer to Figure 2 and Figure 3 The connecting buckle 14 includes a buckle base plate 141, two bolts 142, and two nuts 143. The bolts 142 are disposed on the buckle base plate 141. The connecting part 112 is provided with two first connecting holes 1121, and the L-shaped fixing base 13 is provided with two second connecting holes 131. The bolts 142 pass through the first connecting holes 1121 and the second connecting holes 131 and are then fixed with nuts 143. Preferably, the bolts 142 are welded to the buckle base plate 141.

[0031] For more details, please refer to Figure 2 and Figure 3 Two adjacent first connecting holes 1121 are parallel elongated oval holes, and two adjacent second connecting holes 131 are parallel elongated oval holes. The two ends of the snap-on base plate 141 are respectively provided with inward edging 144. The edging 144 abuts against the connecting part 112 and the L-shaped fixing base 13. The connecting part 112 can move relative to the L-shaped fixing base 13 along the extension direction of the first connecting hole 1121, so the extension length of the two can be adjusted. Because there are two parallel elongated oval holes 1121 and 131 at the connection of the connecting part 112 and the L-shaped fixing base 13, plus the edging 144 of the snap-on base plate 141, the base 11 and the panel fixing part 12 can only move in a straight line in one direction and cannot rotate. When the nut 143 is tightened, not only can the reliability of the connection be guaranteed, but it can also adapt to different door jamb 200 thicknesses or different door frame 300 thicknesses.

[0032] For more details, please refer to Figures 2 to 4The other end of the L-shaped fixed base 13 is provided with two fixing holes 132. The fixing holes 132 are oblong holes. The fixing holes 132 are placed on the inner wall of the elevator shaft and fixed to the door jamb 200 by expansion bolts.

[0033] Preferably, the length of the panel fastener 12 is the same as the length of the fixing part 111, the width of the panel fastener 12 is greater than the width of the fixing part 111, and the thickness of the panel fastener 12 is greater than the thickness of the fixing part 111, which can improve the accuracy of blind screw driving after the cover panel 2 is added.

[0034] For more details, please refer to Figure 5 and Figure 6 The panel fastener 12 is made of wood or a lightweight, high-strength material, and the panel 2 is also made of wood or a lightweight, high-strength material. Preferably, both the panel fastener 12 and the panel 2 are made of wood. Considering that the panel 2 needs to be fixed to the base 11 and reused repeatedly, directly fixing screws to the base 11 would be difficult to install due to the metal material of the base 11, and would also reduce the service life of the base 11. The panel fastener 12 provides an easy-to-replace and low-cost option, and the wooden panel fastener 12 is an easy-to-install screw connection medium.

[0035] In another embodiment of this example, the fixing part 111 and the connecting part 112 are connected by a connecting buckle 14. The distance between the fixing part 111 and the connecting part 112 is adjustable, so as to meet the sealing of elevator door openings of different widths. The telescopic adjustment between the fixing part 111 and the connecting part 112 is the same as the adjustment method of the connecting part 112 and the L-shaped fixing base 13, which will not be described again here.

[0036] When using this utility model, the following steps are included:

[0037] 1) Assemble the fixed panel module 1. At the beginning, measure the distance from the inner wall of the door jamb 200 to the door frame 300 outside the elevator hall door, and adjust the connecting part 112 and the L-shaped fixed base 13 accordingly. Then lock them through the connecting buckle 14, and prepare the corresponding quantity in sequence.

[0038] 2) Install and fix panel module 1, please refer to [link / reference]. Figure 4 After the elevator hall door is removed, the L-shaped fixing base 13 of the fixing panel module 1 is fixed to the inner wall of the door jamb 200, i.e., inside the elevator shaft. The L-shaped fixing base 13 is fixed to the inner wall of the door jamb 200 by expansion bolts. Two fixing panel modules 1 are fixed at the top and bottom of each door opening. The number of fixing panel modules 1 can exceed two. This embodiment uses two for distance description.

[0039] 3) Install panel 2, please refer to Figure 1 , Figure 5 and Figure 6 After covering the doorway with panel 2, gently press panel 2 with your hand to locate the panel fixing member 12 in the fixed panel module 1, and then use screws to fix panel 2 to panel fixing member 12. This method is simple and easy to construct, and screws can be driven blindly; when there are too many holes in panel fixing member 12, it is also easy to replace, and the cost is low. The entire device construction does not require the use of complex mechanisms, making construction efficient and convenient.

[0040] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0041] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
