Description

Technical Field

[0001] This utility model relates to the field of municipal building maintenance technology, specifically to a protective device for municipal building maintenance. Background Technology

[0002] Municipal buildings refer to public buildings constructed with government funding. They generally refer to various administrative buildings and public service buildings within a planning area, including government buildings, public entertainment facilities, urban transportation facilities, educational, scientific research and cultural institutions, and medical and health institutions. When repairing municipal buildings, protective warning barriers are needed to remind passersby to pay attention to the construction work.

[0003] The protective device for municipal building maintenance described in publication CN222276389U can be lengthened by adding additional protective plates A and B. In this case, the slot on protective plate A is aligned with the insert on protective plate B, and the insert is inserted into the slot and tightened. Next, the stabilizing mechanism is rotated. After the threaded sleeve contacts the blocking plate, the screw is rotated, causing the stabilizing seat to rotate. Once the stabilizing seat contacts the ground, the entire protective device can be lengthened, and after lengthening, each section of the protective device can be stabilized on both sides, improving the stability of the device. However, the existing technology still has shortcomings:

[0004] 1. Although existing technologies can lengthen the protective device as a whole, when the protection range is large, the number of devices used will be large, which will increase the production and transportation costs of municipal building maintenance.

[0005] 2. Existing technology requires lifting the protective plate by pulling the handle, which is laborious and inconvenient to use.

[0006] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

With the help of the guide rod 3.2, the limiting grooves 3.6 and the limiting plate 3.5, the support plate 3.1 can be moved up and down in the base 2. Thus, during transportation, the universal wheels 7 can extend downward from the inside of the base 2 to lift the protective plate 1, eliminating the need for workers to manually lift and carry it, saving time and effort. When protecting, the universal wheels 7 are retracted into the inside of the base 2, so that the base 2 contacts the ground and prevents the protective plate 1 from moving.

[0039] An extension mechanism 4 is provided inside the wall panel 1, including a movable compartment 4.1, a shaft 4.2, a fixed plate 4.3, a first gear 4.4, a second lead screw 4.5, a second gear 4.6, a second protective plate 4.7, a threaded groove 4.8, and a handle 4.9. The movable compartment 4.1 is located in the middle of the interior of the first protective plate 1. The shaft 4.2 is located on the upper side of the interior of the movable compartment 4.1. The fixed plate 4.3 is rotatably connected to the middle of the outer side of the shaft 4.2, and the fixed plate 4.3 is fixed to the interior of the movable compartment 4.1. The shaft 4.2 is fixedly connected to a gear 4.4 at its lower end. A lead screw 4.5 is rotatably connected between the two side walls of the movable chamber 4.1. The lead screws 4.5 are symmetrically arranged about the shaft 4.2, with opposite thread directions. A gear 4.6 is fixedly connected to one end of each lead screw 4.5. The gear 4.6 is located inside the movable chamber 4.1. Both gears 4.4 and 4.6 are bevel gears, and they mesh.

[0040] Protective plate 2 4.7 is slidably connected to both ends inside protective plate 1. A threaded groove 4.8 is formed in the middle of opposite sides of protective plate 2 4.7.

A handle 4.9 is fixedly connected to the upper end of shaft 4.2, which passes through protective plate 1. The handle 4.9 is equipped with a self-locking pin structure. By rotating the handle 4.9, shaft 4.2 and gear 1 4.4 are rotated, controlling protective plate 2 4.7 to move synchronously laterally to both sides along the interior of protective plate 1, moving closer or further apart. During transportation, protective plate 2 4.7 is stored inside the cavity of protective plate 1; during protection, it extends to both sides, increasing the protective area. This reduces the number of devices used during assembly, significantly lowering the production and transportation costs of municipal building maintenance.

[0041] A connecting mechanism 5 is provided at one end of the protective plate 4.7 that is away from the first protective plate. The mechanism includes a connecting plate 5.1, a connecting groove 5.2, a screw hole 5.3, and a screw hole 5.4.

The connecting groove 5.2 has screw holes 5.4 on its upper and lower sides. The screw holes 5.3 and the screw holes 5.4 are adapted to each other. This allows the connecting plates 5.1 of one set of protective plates 1 to be inserted into the connecting grooves 5.2 of another set of protective plates 1. Then, the screw holes 5.3 and 5.4 are connected together by bolts to continuously splice the protective device, thereby increasing the protection range.

[0042] In specific implementation of this utility model, such as Figure 1As shown, during municipal building maintenance, turning knob 3.4 drives screw 3.3 to rotate, which in turn moves support plate 3.1 downward through lifting mechanism 3, allowing caster 7 to extend downward from the base 2, lifting protective plate 1. Protective plate 1 is then pushed for transport. When transported to the protected area, knob 3.4 is turned again to retract caster 7 back into the base 2, ensuring the base 2 contacts the ground and maintains the stability of protective plate 1. Turning handle 4.9 controls extension mechanism 4 to extend protective plate 4.7 from the inside of protective plate 1 to both sides, increasing the protected area. Another set of protective devices is moved to one side of protective plate 4.7, allowing connecting plate 5.1 of one set of protective plates 1 to be inserted into connecting groove 5.2 of the other set. Bolts are then used to connect screw hole 5.3 and screw hole 5.4 together. The protective device is then spliced ​​and extended according to the protected area.
