Description

Technical Field

[0001] The utility model relates to the technical field of construction site safety protection, in particular to a temporary protection structure for an elevator shaft. Background Art

[0002] Existing house buildings often use frame structures. During the construction process, an elevator shaft is often reserved to facilitate the subsequent installation of the elevator. Since the elevator shaft has a door opening, there will be certain risks if protective measures are not installed during the construction process. Some existing temporary protection methods for the door openings of the elevator shaft are usually to fix a metal protective net with expansion bolts. The temporary protection of the elevator shaft opening by fixing the metal net with expansion bolts will not only cause damage to the building body, but also the metal net is not convenient to disassemble and assemble. Moreover, since the safety protection metal net is not allowed to be disassembled during the construction process, the temporary protection of the elevator shaft opening by fixing the metal net will also affect the decoration construction at the elevator shaft door opening. Therefore, a temporary protection structure for the elevator shaft is proposed to address the above problems. Utility Model Content

By making the positioning pin 7 contact with the inner wall of the elevator shaft under the elastic force of the first spring 9 on the slide plate 8, the tightness of the contact between the positioning pin 7 and the inner wall of the elevator shaft is better.

[0030] Example 4

[0031] like Figure 5-6 As shown, in order to solve the problem that it is inconvenient to fold up the metal mesh 13 when the device is finished using, the upper and lower ends of the outer side of the fixed shaft 11 are fixedly connected with springs 14, and the other end of the spring 14 is fixedly connected to the support rod 10. When the device is finished using, the fixed shaft 11 drives the reel 12 to reel up the metal mesh 13 under the elastic force of the spring 14, which facilitates the folding of the metal mesh 13.

[0032] Example 5

[0033] like Figure 1 , Figure 5 , Figure 6 and Figure 7As shown, in order to solve the problem that it is inconvenient to position the metal mesh 13 on the outside of the fixed plate 6 on one side, the front end of the fixed plate 6 at the bottom end is fixedly connected with a positioning block 15, and the inner side of the positioning block 15 is fixedly connected with a second spring 16, and the other end of the second spring 16 is fixedly connected with a clamping block 17 that penetrates the positioning block 15, and the clamping block 17 is slidably connected to the positioning block 15, and the front end of the clamping block 17 is inclined.

After positioning, the clamping rod 18 is pushed to compress the third spring 19, and one side of the clamping rod 18 is further made to slide out of the clamping groove on one side of the support rod 10, and then the support rod 10 at the front end of the inner side of the fixing rod 1 is taken out. After taking it out, the support rod 10 on one side is first put on the outer side of the positioning block 15 on one side, so that the positioning block 15 on one side is located at one side. In the card slot on the side support rod 10, when the support rod 10 on one side contacts the oblique edge of the card block 17 on the positioning block 15 on one side, the corresponding card block 17 will be inserted into the card hole on the outside of the support rod 10 on one side after compressing the corresponding second spring 16, thereby realizing the positioning of the support rod 10 on one side, and then pulling the support rod 10 on the other side to make the metal mesh 13 rotate out from the outside of the winding wheel 12. At this time, the clockwork spring 14 will continue to shrink during the rotation of the fixed shaft 11, and then the support rod 10 on the other side is put on the outside of the positioning block 15 on the other side to position the support rod 10 on the other side, thereby realizing the positioning of the metal mesh 13 on the inner side of the elevator shaft door opening for protection through the support rod 10. When the device is used and removed, the device can be easily carried and stored by resetting the metal mesh 13 and the support rod 10.
