Description

Technical Field

[0001] This utility model belongs to the field of cleaning product structure technology, specifically referring to a cloth-clamping mop head. Background Technology

[0002] Flat mops are convenient to use, but the mop head needs to be removed for washing, requiring frequent reassembly and disassembly. To improve usability, clip-on mops have been designed, allowing for replacement of the mop head and providing significantly better mopping results.

[0003] For example, Chinese Patent CN202021481660.3 discloses a cloth-clamping mopping device, characterized in that it includes: a driving mechanism, a base, a clamping member, and a locking mechanism; the driving mechanism is connected to the clamping member in a transmission manner, the clamping member is movably disposed with respect to the base, an elastic member is disposed between the clamping member and the base, and the locking mechanism is used to lock the position of the clamping member relative to the base; the driving mechanism is used to drive the clamping member to move relative to the base, so that the elastic member is compressed and deformed by the clamping member and the base, and to move the clamping end of the clamping member toward the base until the base and the clamping end of the clamping member clamp the cloth to be clamped, and to lock the locking mechanism; when the locking mechanism is unlocked, the elastic member pushes the clamping member to move relative to the base under the action of elastic force, so that the clamping end of the clamping member moves away from the base, thereby releasing the cloth to be clamped. This product offers users a convenient way to clamp fabric, but it also has some drawbacks: the cap and base are connected by a linkage assembly, which requires workers to assemble them in a small space, making assembly difficult, resulting in low assembly efficiency and high assembly costs. Summary of the Invention

[0004] The purpose of this invention is to provide a cloth-clamping mop head that is simple in structure and easy to install.

[0005] The purpose of this utility model is achieved as follows:

[0006] A cloth-clamping mop head includes a lower body, clamping plates slidably disposed on both sides of the lower body, and a lifting plate movably disposed above the lower body. A driving structure is disposed on the clamping plates. During the descent of the lifting plate, the driving structure can be driven to control the clamping plates to abut against the sides of the lower body. An elastic element is disposed on the clamping plate or the driving structure, and the elastic element provides a force to the clamping plate away from the lower body.

[0007] The drive structure includes a first transmission rod and a second transmission rod. Under the action of the elastic element, the connection position of the first transmission rod and the second transmission rod arches upward. The lifting plate moves downward, and the lifting plate can push the arched part of the first transmission rod and the second transmission rod. The first transmission rod and the second transmission rod rotate, thereby driving the clamping plate to stick to the lower body.

[0008] The lifting plate is equipped with a latch. When the lifting plate is in a low position, the latch engages with the lower body and keeps the lifting plate in a low position.

[0009] Furthermore, the first transmission rod is hinged to the lower main body, the second transmission rod is hinged to the support arm of the clamping plate, the lower main body is provided with a slide rail, and the support arm of the clamping plate moves along the slide rail.

[0010] Furthermore, one end of the elastic element abuts against the support arm of the clamping plate / clamping plate, and the other end abuts against the lower body; or, the two ends of the spring are respectively connected to the support arms of the two clamping plates / clamping plates.

[0011] Furthermore, the support arm of the clamp has an elastic element placement cavity, with one end of the elastic element abutting against the lower body and the other end built into the elastic element placement cavity.

[0012] Furthermore, the lower body is provided with a transverse inner groove, and the support arm of the clamping plate, the first transmission rod, and the second transmission rod are all arranged in the transverse inner groove. The support arm of the clamping plate is located below the first transmission rod and the second transmission rod. The slide rail is provided on the side wall of the transverse inner groove.

[0013] Furthermore, the lower body is provided with at least one retaining inner groove, and the support arm of the clamp plate is limited on the retaining inner groove.

[0014] Furthermore, the lower body is provided with a longitudinal track, and the lifting plate moves along the longitudinal track but cannot detach from the longitudinal track.

[0015] Furthermore, the lower body is provided with two longitudinal tracks, and the lifting plate is provided with a protrusion, the inner cavity of which is adapted to the longitudinal track; an anti-detachment part is provided on the longitudinal track, and when the lifting plate reaches the high position, the lifting plate abuts against the anti-detachment part.

[0016] Furthermore, the latch is provided in the concave cavity of the protrusion, and the pushing part of the latch is exposed; the elastic element provides a force to the hook of the latch to engage with the lower body.

[0017] Furthermore, the clamping plate rests against the side of the lower main body, and the clamping teeth of the clamping plate engage with the clamping teeth of the lower main body; the lower main body has a slide rail that limits the support arm of the clamping plate, the support arm of the clamping plate moves along the slide rail, the slide rail is provided with a flange, and the support arm of the clamping plate is provided with a recess that mates with the flange; when the clamping plate is away from the lower main body, the flange abuts against the surface of the support arm of the clamping plate, the clamping teeth of the clamping plate are lower than the clamping teeth of the lower main body, and when placed on the ground, the clamping teeth of the clamping plate contact the ground, and the lower main body is suspended in the air; when the clamping plate rests against the side of the lower main body, the flange is located in the recess, and under the action of the recess, the clamping plate can float up and down.

[0018] Furthermore, the clamping plate or lower body is provided with a protruding edge. When the clamping plate is against the lower body, the first transmission rod or the second transmission rod abuts against the protruding edge, and the protruding edge keeps the first transmission rod or the second transmission rod in an arched state; or, the lower end of the first transmission rod or the second transmission rod is provided with a protruding edge. When the clamping plate is against the lower body, the protruding edge of the first transmission rod or the second transmission rod abuts against the clamping plate or the lower body, and the protruding edge keeps the first transmission rod or the second transmission rod in an arched state.

[0019] The outstanding and beneficial technical effects of this utility model compared to the prior art are:

[0020] 1. This utility model simplifies the drive structure, which consists of a first transmission rod and a second transmission rod hinged together. When no external force is applied, the elastic element causes the connection point between the first and second transmission rods to arch upwards. During the descent of the lifting plate, the first and second transmission rods rotate in a horizontal direction, thereby pulling the clamping plates on both sides closer to the lower body. The advantages of this structure are: a) The drive structure is installed on the lower body, providing sufficient operating space on the upper surface of the lower body for easy assembly by workers; b) The lifting plate and the drive structure are not directly connected; the lower surface of the lifting plate rests against the hinge point between the first and second transmission rods, simplifying the product structure.

[0021] 2. The lower main body of this utility model is provided with a transverse inner groove. The support arm of the clamping plate, the first transmission rod, and the second transmission rod are all arranged in the transverse inner groove, and the support arm of the clamping plate is located below the first transmission rod and the second transmission rod. By limiting the drive structure through the transverse inner groove and placing the support arm of the clamping plate below the drive structure, the support arm of the clamping plate can be effectively limited, ensuring the stability of its movement.

[0022] 3. An anti-detachment structure is provided between the lower main body and the lifting plate of this utility model. That is, the lifting plate slides up and down along the longitudinal track, and when the lifting plate reaches the high position, it abuts against the anti-detachment part. This structure makes assembly more convenient for workers. After the lower main body and the drive structure are assembled, the lock is installed on the lifting plate, and finally the lifting plate and the lower main body are connected. The installation is convenient and the assembly difficulty is reduced.

[0023] 4. The clamping teeth of this utility model are lower than the clamping teeth of the lower body. When placed on the ground, the clamping teeth of the clamping plate are in contact with the ground, and the lower body is suspended in the air. By setting the height difference between the clamping teeth of the clamping plate and the clamping teeth of the lower body, the clamping teeth of the clamping plate can effectively abut against the surface of the wiping cloth. During the process of clamping plate shrinking, the clamping teeth of the clamping plate can better push the wiping cloth to deform and bite between the clamping teeth of the clamping plate and the clamping teeth of the lower body.

Detailed Implementation

[0040] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. Figure 1-15 As shown:

[0041] A mop head with a clamping mechanism includes a lower body 1, with clamping plates 3 slidably mounted on both sides of the lower body 1. A lifting plate 2 is movably mounted above the lower body 1. A driving structure 4 is mounted on the clamping plates 3. During descent, the lifting plate 2 drives the driving structure to control the clamping plates to abut against the sides of the lower body 1. Elastic elements are provided on the clamping plates or driving structure, providing a force to the clamping plates 3 away from the lower body 1. The elastic elements can be common components such as springs 44 or soft rubber. Preferably, one end of the elastic element abuts against the clamping plate / clamping plate support arm, and the other end abuts against the lower body 1; alternatively, both ends of the spring are connected to the two clamping plates / clamping plate support arms respectively. Both installation methods are acceptable, and manufacturers can decide on the installation method according to their own circumstances. The lifting plate can be independently equipped with elastic elements to maintain its high position, or it can utilize the elastic elements on the driving structure / clamping plate to maintain its high position.

[0042] The drive structure 4 includes a first transmission rod 41 and a second transmission rod 42. Under the action of the elastic element, the connection position of the first transmission rod 41 and the second transmission rod 42 arches upward; the lifting plate 2 moves downward, and the lifting plate can push the arched parts of the first transmission rod and the second transmission rod, causing the first transmission rod and the second transmission rod to rotate, thereby driving the clamping plate to press against the lower body. The lifting plate 2 is provided with a latch 5. When the lifting plate is in the low position, the latch 5 engages with the lower body 1 and keeps the lifting plate 2 in the low position. This structure is easy for the user to operate. By releasing the latch, under the action of the elastic element, the two clamping plates separate, the lifting plate rises, the wiping cloth is placed on the ground, the cloth-clamping mop is placed above the wiping object, and then the handle is pushed down, the lifting plate moves down, and the two clamping plates press against the side of the lower body under the action of the first transmission rod and the second transmission rod, thereby clamping the wiping object. The wiping object can be common items such as washcloths, napkins, wet wipes, and towels. In particular, the transmission structure of this application is fully mounted on the lower body, and the upper surface of the lower body has sufficient operating space to facilitate assembly by workers; furthermore, the lifting plate and the drive structure are not directly connected, and the lower surface of the lifting plate abuts against the hinge position between the first transmission rod and the second transmission rod, which simplifies the product structure.

[0043] The first transmission rod 41 is hinged to the lower body 1, and the second transmission rod 42 is hinged to the support arm 31 of the clamping plate. The lower body 1 is provided with a transverse inner groove 11. The support arm 31 of the clamping plate, the first transmission rod 41, and the second transmission rod 42 are all arranged in the transverse inner groove 11, and the support arm of the clamping plate is located below the first transmission rod and the second transmission rod. The side wall of the transverse inner groove 11 forms a slide rail for the movement of the support arm of the clamping plate.

[0044] The support arm 31 of the clamping plate has an elastic element placement cavity 311, with one end of the elastic element abutting against the lower main body 1 and the other end housed within the elastic element placement cavity 311. The elastic element is stably placed by providing the elastic element placement cavity 311.

[0045] The lower body 1 is provided with at least one retaining inner groove 12, and the support arm 31 of the clamping plate is limited on the retaining inner groove 12. Both the retaining inner groove 12 and the transverse inner groove 11 are guide structures, allowing the clamping plate 3 to move stably.

[0046] The lower body 1 is provided with two longitudinal tracks 13, and the lifting plate 2 is provided with a protrusion 21, the inner cavity 211 of which is adapted to the longitudinal tracks 13; an anti-detachment part 131 is provided on the longitudinal tracks 13, and when the lifting plate 2 reaches the high position, the lifting plate 2 abuts against the anti-detachment part 131. Preferably, as follows... Figure 13 and Figure 15As shown, the anti-detachment part can be a raised edge or a buckle. The lifting plate 2 is also provided with a lifting plate buckle 23 that cooperates with the raised edge or buckle. When the worker assembles the lifting plate and the lower body, the lifting plate buckle is deformed and passes through the anti-detachment part to complete the installation without the need for special tooling fixtures.

[0047] The latch 5 is disposed within the concave cavity of the protrusion, with the latch's pushing part 51 exposed. The elastic element applies force to the latch's hook 52, causing it to engage with the lower main body latch 14. Figure 15 As shown, a lifting plate protrusion is provided below the lifting plate, and the latch can move stably along the track formed by the lifting plate protrusion.

[0048] The clamping plate 3 abuts against the side of the lower body 1, and the clamping teeth 30 of the clamping plate engage with the clamping teeth 10 of the lower body. The lower body has a slide rail for limiting the support arm of the clamping plate, and the support arm of the clamping plate moves along the slide rail. The slide rail refers to the transverse inner groove 11 and the retaining inner groove 12. A flange 121 is provided on the slide rail, and the support arm of the clamping plate is provided with a recess 312 that mates with the flange 121. When the clamping plate moves away from the lower body, the flange abuts against the surface of the support arm of the clamping plate, and the clamping teeth of the clamping plate are lower than the clamping teeth of the lower body. When placed on the ground, the clamping teeth of the clamping plate are in contact with the ground, and the lower body is suspended. By setting a height difference L between the clamping teeth of the clamping plate and the clamping teeth of the lower body, the clamping teeth of the clamping plate can effectively abut against the surface of the wiping cloth. During the contraction of the clamping plate, the clamping teeth of the clamping plate can better push the wiping cloth to deform and engage between the clamping teeth of the clamping plate and the clamping teeth of the lower body. When the clamping plate is attached to the side of the lower body, the flange 121 is located in the recess 312. Under the action of the recess, the clamping plate can float up and down. The space of the up and down floating provides a buffer for the clamping plate and also reduces the height difference L between the clamping teeth of the clamping plate and the clamping teeth of the lower body. When the wiping material is installed on the mop head, the wiping material itself also has a certain thickness, and the wiping material on the surface of the lower body can also contact the ground.

[0049] The clamping plate or lower body is provided with a protruding edge 32. When the clamping plate 3 is against the lower body 1, the first transmission rod 41 or the second transmission rod 42 abuts against the protruding edge 32, and the protruding edge keeps the first transmission rod or the second transmission rod in an arched state; or, the lower end of the first transmission rod or the second transmission rod is provided with a protruding edge, and when the clamping plate is against the lower body, the protruding edge of the first transmission rod or the second transmission rod abuts against the clamping plate or the lower body, and the protruding edge keeps the first transmission rod or the second transmission rod in an arched state. Both solutions are acceptable, and the manufacturer can choose one solution for production. The purpose of setting the protruding edge is: when the clamping plate is against the lower body, the protruding edge keeps the first transmission rod or the second transmission rod in an arched state, such as... Figure 3 As shown, this arch is designed to allow the spring to drive the first or second transmission rod to rotate with less effort. This protruding edge can also provide a limiting function when the clamping plate is away from the lower body, such as... Figure 12As shown, when the lifting plate is held in a high position, the first or second transmission rod abuts against the convex edge to prevent the first or second transmission rod from arching excessively and to ensure the stability of the structure.

[0050] The mop head of this application can be connected to a handle: a connecting rod 9 is rotatably mounted above the lifting plate of the mop head. The handle is not shown in the attached drawings. The handle being fixed to the connecting rod 9 is a well-known structure in the industry. The fixing structure between the handle and the connecting rod can be a snap-fit ​​connection or a threaded connection. The mop head of this application can also be directly connected to a grip handle: a handle is fixed or integrally formed on the lifting plate of the mop head, allowing the user to directly grip the handle and use it as a small desktop mop.

[0051] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape, and principle of the present utility model should be covered within the scope of protection of the present utility model.
