Description

Technical Field

[0001] This utility model relates to the field of cleaning products technology, specifically a flat mop base plate structure. Background Technology

[0002] Traditional mop designs often present numerous inconveniences in securing the mop head. Common methods include using cable ties, Velcro, or sewing directly to the mop base. These methods are cumbersome to use, and when changing the mop head, users need to spend considerable time and effort disassembling and reassembling, which is not only inefficient but also prone to damaging the mop head or the mop base. Furthermore, traditional securing methods often fail to ensure the mop head's stability during use, allowing it to loosen or fall off, affecting cleaning performance. Therefore, a flat mop base structure has been proposed. Utility Model Content

[0003] The purpose of this utility model is to provide a flat mop base plate structure to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a flat mop base plate structure, including a base plate for supporting the mop cloth, with a metal plate for reinforcement, such as a stainless steel mirror panel embedded in the base plate, which can enhance the strength of the base plate while controlling its thinness. A connector is provided in the middle of the upper surface of the base plate, and a screw hole is provided on the base plate. The threaded end of a screw passes through the screw hole from the bottom of the base plate, and then the threaded end of the screw is screwed onto the connector. The screw hole and the screw can fix the connector onto the base plate. Two clamping components are symmetrically arranged on the base plate and on both sides of the connector. The clamping components include a fixing plate, which is fixedly connected to the upper surface of the base plate. The fixing plate is fixed in the same way as the connector, that is, the threaded end of the screw is screwed onto the fixing plate, and the screw hole and the screw can fix the fixing plate onto the base plate. Pressure plates are provided on both sides of the fixing plate, and multiple pressure strips for pressing the sides of the mop cloth are fixedly connected to the pressure plates.

[0005] Preferably, the clamping assembly further includes a rotating block, which is fixedly connected to the side wall of the pressure plate. Two rotating blocks are fixed on each pressure plate, and each rotating block is provided with a rotating shaft. The rotating shafts on the two rotating blocks are coaxially arranged, and the rotating shafts are movably connected to the inside of the rotating groove. The rotating groove is opened inside the fixed plate. An eccentric rod is fixed between the two rotating blocks on the same pressure plate, and a tension spring is connected between the two eccentric rods.

[0006] Preferably, a clamping plate is fixedly connected to the side wall of the pressure plate, and a support platform is provided on the side wall of the fixed plate, with the clamping plate movably clamping against the side wall of the support platform.

[0007] Preferably, a fixing rod is fixed between two rotating blocks on the same pressure plate, the fixing rod is arranged parallel to the eccentric rod, and multiple connecting blocks are provided between the fixing rod and the eccentric rod.

[0008] Preferably, the lower end of the pressure strip is provided with a first pressure tooth.

[0009] Preferably, the base plate is provided with second pressure teeth on both sides.

[0010] Preferably, on the pressure plate, the pressure strip away from the rotating block is arc-shaped, so that one side of the pressure plate forms a hand groove that facilitates manual prying and upward rotation of the pressure plate.

[0011] Compared with existing technologies, the advantages of this invention are as follows: This invention reduces the thickness of the base plate while ensuring strength through the interlocking of metal plates, facilitating cleaning. The combined design of the rotating block, rotating shaft, eccentric rod, and tension spring enables flexible pressing and quick release of the pressure plate against the side of the mop. When installing the mop, the pressure plate tightly adheres to the side of the mop under the elastic force of the tension spring. The eccentric rod's position below the rotating block keeps the tension spring in a stretched state, ensuring the mop is firmly pressed against the base plate, preventing loosening or falling off during use, and enhancing the cleaning effect.

[0012] When it's time to change the mop head, the user simply flips up the pressure plate, and the eccentric rod rotates to the upper position along with the pivot on the rotating block. At this point, the tension spring not only doesn't hinder the opening of the pressure plate, but also keeps it open, facilitating quick installation and removal of the mop head. This simplifies the operation process, greatly improves the efficiency of mop head replacement, and brings significant convenience to the user. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-9 This utility model provides a technical solution: a flat mop base plate structure, including a base plate 1 for supporting the mop cloth, a metal plate 9 disposed on the base plate 1, the metal plate 9 being located on the upper side of the base plate 1, for example, a mirror-finished stainless steel metal plate embedded in the base plate 1, which can enhance the strength of the base plate 1 while reducing the thickness of the material used for the base plate 1, and the smooth mirror material makes it easy to clean. A connector 2 is disposed in the middle of the upper surface of the base plate 1, and a screw hole 8 is disposed on the base plate 1 (the screw hole 8 also penetrates the metal plate 9). The threaded end of the screw passes through the screw hole 8 from the bottom of the base plate 1, and then the threaded end of the screw is screwed onto the connector. On connector 2, screw holes 8, when used with screws, can fix connector 2 to base plate 1. On base plate 1, two clamping components 3 are symmetrically arranged on both sides of connector 2. The clamping components 3 include fixing plates 301, which are fixedly connected to the upper surface of base plate 1. Fixing plate 301 is fixed in the same way as connector 2, that is, the threaded end of the screw is screwed into fixing plate 301. Screw holes 8, when used with screws, can fix fixing plate 301 to base plate 1. Pressure plates 302 are provided on both sides of fixing plate 301. Multiple pressure strips 303 for pressing the sides of mop are fixedly connected to pressure plates 302.

[0025] like Figure 1-4 as well as Figure 6-9 As shown, in order to quickly remove the pressed mop side to facilitate quick installation and removal of the mop onto the base plate 1, the clamping assembly 3 specifically includes a rotating block 304. The rotating block 304 is fixedly connected to the side wall of the pressure plate 302. Two rotating blocks 304 are fixed on each pressure plate 302. Each rotating block 304 is provided with a rotating shaft 305. The rotating shafts 305 on the two rotating blocks 304 are coaxially arranged. The rotating shaft 305 is movably connected to the inside of the rotating groove 306. The rotating groove 306 is opened inside the fixed plate 301. An eccentric rod 307 is fixed between the two rotating blocks 304 on the same pressure plate 302. A tension spring 308 is connected between the two eccentric rods 307.

[0026] The lower end of the rotating groove 306 is open. During installation: connect both ends of the tension spring 308 to the two eccentric rods 307 respectively, and then install the two pressure plates 302 on the fixed plate 301. At this time, the rotating shaft 305 is placed inside the rotating groove 306 (e.g., Figure 3 As shown), in this state, the fixing plate 301 is fixed to the base plate 1, so that the fixing plate 301 limits the pressure plate 302 to the base plate 1;

[0027] like Figure 7 As shown, when the pressure plate 302 and the fixing plate 301 are in a horizontal state, that is, when the pressure strip 303 presses the mop against the upper surface of the base plate 1, the eccentric rod 307 is located below the center of the rotating block 304. In this state, the distance between the two eccentric rods 307 is greater than the length of the tension spring 308 in its natural state, causing the tension spring 308 to be in a stretched state. Under the elastic force of the tension spring 308 contraction, the two pressure plates 302 are pulled towards the base plate 1, causing the pressure strip 303 to press the mop against the upper surface of the base plate 1 more firmly.

[0028] When the mop needs to be removed from the base plate 1, swing the pressure plate 302 upwards. The pressure plate 302 will then rotate upwards. During this rotation, the eccentric rod 307 will rotate around the pivot 305 of the rotating block 304. During this rotation, the eccentric rod 307 will rotate to a position above the pivot 305 (e.g., ...). Figure 9 As shown in the figure, under the tension of the tension spring 308, the pressure plate 302 will be kept in the open state, which is conducive to installing the mop on the base plate 1 or removing the mop from the base plate 1.

[0029] like Figure 7-9 As shown, in order to keep the pressure plate 302 stably in the open state, specifically, a pressing plate 309 is fixedly connected to the side wall of the pressure plate 302, and a support platform 3010 is provided on the side wall of the fixing plate 301, and the pressing plate 309 is movably pressed against the side wall of the support platform 3010.

[0030] like Figure 9 As shown, there is an angle between the support platform 3010 and the side wall of the fixed plate 301. When the pressure plate 302 rotates upward, when the pressing plate 309 of the pressure plate 302 passes the corner position between the support platform 3010 and the side wall of the fixed plate 301, the eccentric rod 307 on the pressure plate 302 will further stretch the tension spring 308. When the pressing plate 309 on the pressure plate 302 passes the corner, under the pulling action of the tension spring 308, the pressing plate 309 moves towards the support platform 3010 and presses against it. In this way, the pressure plate 302 can be stably kept in the open state.

[0031] When the clamping plate 309 and the pressure plate 302 move relative to the fixed plate 301, the rotating shaft 305 rotates in the rotating groove 306 and slides in the rotating groove 306, which is conducive to the normal movement of the clamping plate 309 and the pressure plate 302.

[0032] like Figure 3 , 4 As shown in Figure 7, in order to increase the strength of the eccentric rod 307, specifically, a fixing rod 4 is fixed between two rotating blocks 304 on the same pressure plate 302. The fixing rod 4 is arranged parallel to the eccentric rod 307, and multiple connecting blocks 5 are provided between the fixing rod 4 and the eccentric rod 307.

[0033] like Figure 3-4 As shown, in order to further increase the stability of the pressing strip 303 pressing the mop, specifically, the lower end of the pressing strip 303 is provided with a first pressing tooth 6, and the two sides of the base plate 1 are provided with a second pressing tooth 7.

[0034] Specifically, on the pressure plate 302, the pressure strip 303 away from the rotating block 304 is arc-shaped, so that one side of the pressure plate 302 forms a hand groove 3011 that facilitates manual prying to rotate the pressure plate 302 upward.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
