Technical Field
[0001] The present application relates to the technical field of cleaning tools, and in particular to a device for cleaning elevator car door sills and landing door sills. Background Art
[0002] In the tedious daily maintenance of elevators, cleaning the sills between car doors and landing doors is always a frequent and challenging task. Usually, maintenance personnel will first use a brush to perform preliminary cleaning to gather various sundries and debris scattered on the sills for subsequent centralized processing.
[0003] However, this process is often time-consuming and labor-intensive, and the results are not very ideal. Next, maintenance personnel will use tweezers and their fingers to remove the debris gathered by the brush one by one. This process is not only time-consuming, but also difficult to clean thoroughly due to the different shapes and sizes of the debris. For the harder dirt attached to the sill, maintenance personnel have to use a flat-blade screwdriver to remove it, which not only increases the difficulty of the work, but also easily damages the surface of the sill.
[0004] After shoveling, maintenance personnel also need to use a brush to clean again to ensure the cleanliness of the sill surface. Finally, for those particularly stubborn or tricky debris, maintenance personnel will use pliers and their own fingers for the final cleaning. However, such a series of tedious operations is not only inefficient, but the cleaning effect is often unsatisfactory. Dirt and debris still remain in many hard-to-reach corners and gaps.
[0005] In order to solve this problem that has long troubled elevator maintenance personnel, we have specially designed and launched an efficient and convenient elevator car door sill and floor door sill cleaning device. Utility Model Content
[0006] The present application provides a device for cleaning elevator car door sills and landing door sills, which aims to solve many problems encountered in cleaning sills during daily elevator maintenance work.
[0007] The present application provides a device for cleaning elevator car door sills and landing door sills using the following technical solutions:
[0008] A device for cleaning elevator car door sills and landing door sills includes a handle rod and a shovel head obliquely arranged on the handle rod, wherein the shovel head is composed of a first flat plate, a second flat plate, and a third flat plate perpendicular to the first and second flat plates, wherein the third flat plate serves as a bottom surface to connect the first and second flat plates and form a groove for storing dirt, and an end of the handle rod away from the shovel head is also provided with a non-slip handle for easy gripping.
[0009] By adopting the above technical solution: the design of the shovel head combines the first flat plate, the second flat plate and the third flat plate to form a groove that can store dirt.

[0017] By adopting the above technical solution, maintenance personnel can precisely adjust the handle rod length by adjusting the relative position between the extension section and the fixed section according to their personal height and cleaning needs. This design provides a wider height adjustment range, allowing the device to adapt to different cleaning scenarios and user needs.
[0018] In addition, the locking piece locks the extension section and the fixed section through the fastening hole to ensure that the handle rod will not loosen or deform due to external force during use. This structure is stable and reliable, ensuring the continuity and safety of the cleaning work.
[0019] Preferably, the locking member is a fixing bolt.
[0020] By adopting the above technical solution: the fixing bolt has high strength and locking force, which can ensure a tight connection between the extension section and the fixed section to prevent loosening or displacement during use. This high-strength locking effect ensures the stability and safety of the handle rod, allowing maintenance personnel to perform cleaning work more confidently. At the same time, the installation and disassembly process of the fixing bolt is relatively simple.

DETAILED DESCRIPTION
[0035] The following is combined with Figure 1-6 This application is described in further detail.
[0036] Example 1
[0037] The present application discloses a device for cleaning elevator car door sills and landing door sills, referring to Figure 1 , including a handle rod 1, a non-slip handle 3 is installed at one end of the handle rod 1, and a shovel head 2 is welded and installed at the other end with the Forbidden City at an angle of 45°. The handle rod 1 and the shovel head 2 are both made of stainless steel. The shovel head 2 is composed of a first flat plate 21, a second flat plate 22 installed parallel to each other, and a third flat plate 23 perpendicular to the first flat plate 21 and the second flat plate 22. The third flat plate 23 serves as the bottom surface to connect the first flat plate 21 and the second flat plate 22 to form a groove for storing dirt. The distance between the first flat plate 21 and the second flat plate 22 is 8-10 mm.
[0038] The working process and implementation principle of Example 1 are as follows:
[0039] The operator first picks up the handle bar 1 of the device. The design of the non-slip handle 3 allows the operator to firmly grasp the handle even when the hands are wet or sweaty, preventing slipping and ensuring safe operation.
[0040] The operator aligns the inclined end of the shovel head 2 with the gap of the elevator car door sill or landing door sill that needs to be cleaned. The 45° angle makes it easier for the shovel head 2 to enter and fit the complex shape of the sill, especially those areas that are difficult to reach with traditional tools.
[0041] By applying appropriate pressure and moving the handle 1 along the gap between the sills, the shovel head 2 begins to scrape away dirt, dust, pebbles, and other debris adhering to the sills. The parallel design of the first and second plates 21, 22 increases the contact area with the gap between the sills, improving cleaning efficiency. Meanwhile, the third plate 23, acting as the bottom surface, forms a groove with the first and second plates 21, 22 to temporarily store the removed dirt, preventing it from scattering during the cleaning process.
[0042] When a certain amount of dirt has accumulated on the shovel head 2, the operator can move the device to a suitable location, such as next to a trash can, and then gently tap the handle rod 1 or the shovel head 2 to make the dirt in the groove fall out for centralized treatment;
[0043] Thanks to the fact that the shovel head 2 is composed of a first flat plate 21, a second flat plate 22 and a third flat plate 23, this design not only increases the contact area with the ground sill gap and improves the cleaning effect, but also realizes temporary storage of dirt through the groove formed by the third flat plate 23, avoiding secondary contamination during the cleaning process.
[0044] Example 2
[0045] Example 2 of the present application discloses a device for cleaning elevator car door sills and landing door sills, referring to Figure 2 The difference from Example 1 is that the shovel head 2 is rotatably mounted on the handle rod 1 through the first flat plate 21, the second flat plate 22, the through hole 4 opened on the handle, and the rotating shaft 5 installed in the through hole 4, and the connection between the shovel head 2 and the handle rod 1 is located 2-3 cm from the front end of the handle rod 1.
[0046] The working process and implementation principle of Example 2 are as follows:
[0047] When cleaning operations are required, the staff can unfold the shovel head 2 to an appropriate angle and use the blade of the shovel head 2 to clean debris and dirt on the elevator car door sill and floor door sill; when operations are not required, the staff can flip the shovel head 2 over and fold it for storage near the handle rod 1. This storage method not only saves space, but also avoids the risk of the shovel head 2 causing damage or scratching other objects during carrying or storage.
[0048] Example 3
[0049] Example 3 of the present application discloses a device for cleaning elevator car door sills and landing door sills, referring to Figure 3 and Figure 4 The difference from Example 1 is that the length of the handle rod 1 is adjustable, and the handle rod 1 consists of an extension section 11 and a fixed section 12 sleeved on the extension section 11, wherein the extension section 11 and the fixed section 12 are penetrated by a fastening hole 6, and a fixing bolt 7 is installed in the fastening hole 6.
[0050] The working process and implementation principle of Example 3 are as follows:
[0051] When cleaning the elevator car door sill and the floor door sill, the user can adjust the length of the handle rod 1 according to actual needs. By loosening the fixing bolt 7, the relative position between the extension section 11 and the fixed section 12 can be freely adjusted to achieve the purpose of adjusting the total length of the handle rod 1. After the adjustment is completed, tighten the fixing bolt 7 again to ensure the stability of the handle rod 1.
[0052] Example 4
[0053] Example 4 of the present application discloses a device for cleaning elevator car door sills and landing door sills, referring to Figure 5 and Figure 6 , which is different from Example 1 in that the length of the handle bar 1 is adjustable, and the handle bar 1 is composed of an extension section 11 and a fixed section 12 that can be sleeved thereon. In particular, fastening holes 6 are designed on both the extension section 11 and the fixed section 12, and these fastening holes 6 are equipped with an innovative press-type fastening device 8. This press-type fastening device 8 is composed of the following parts: a clamping block 81, a pressing plate 82, a rotating shaft 83, a fixing seat 84 and a torsion spring 85. The clamping block 81 is designed to completely match the fastening hole 6, while the torsion spring 85 is installed on the rotating shaft 83, which passes through and is fixed on the fixing seat 84, and the fixing seat 84 is firmly installed on the fixing section 12. The pressing plate 82 realizes the rotation function on the fixing seat 84 through the rotating shaft 83, and the clamping block 81 is installed on the side of the pressing plate 82 close to the fastening hole 6.
[0054] The working process and implementation principle of Example 4 are as follows:
[0055] When the length of the handle rod 1 needs to be adjusted, the user first finds the fastening holes 6 on the extension section 11 and the fixed section 12, then the user gently presses the pressing piece 82 on the press-type fastening device 8 to loosen the block 81 from the current fastening hole 6, and then the user can slide the fixed section 12 relative to the extension section 11 to adjust the total length of the handle rod 1. When it is adjusted to the desired length, the user releases the pressing piece, and the block 81 will automatically pop into the new fastening hole 6 under the action of the torsion spring 85, thereby fixing the length of the handle rod 1.
[0056] With the adjusted handle bar 1 , the user can more conveniently clean the elevator car door sill and the floor door sill. During the cleaning process, the user can adjust the length of the handle bar 1 again as needed to adapt to different cleaning areas and angles.
[0057] The above are preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
