The examples of the present disclosure are described in detail below in conjunction with the accompanying drawings.
Referring to
In this example, the mounting cavity 20 is internally provided with strip-shaped limit bulges. Specifically, the strip-shaped limit bulges are divided into two groups, and are respectively disposed at both ends of the mounting cavity. The at least two limit bulges are available in each group. The limit bulges are in a strip shape, and the length directions thereof are parallel to the length direction of the mop head. A limit chute 24 is formed between the two adjacent limit bulges. Furthermore, the sliding blocks 4 are provided with limit guide rods 43 that can be inserted into the limit chutes and achieve sliding fit, and the length directions of the limit guide rods are parallel to the length direction of the mop head 2, which enables the sliding blocks to slide along the length direction of the mop head. The cross sections of the limit guide rods are rectangular, and can just be inserted into the limit chutes, thereby improving the sliding stability of the sliding blocks, and avoiding deflection.
The mounting cavity 20 is internally provided with first spring support portions, and the first spring support portions are disposed at two ends of the mounting cavity, with two at each end. Furthermore, the sliding blocks 4 are provided with spring mounting columns coaxial with the first spring support portions, and the elastic components are mounted between the first spring support portions and the spring mounting columns to achieve stable support for the springs. In order to improve the mounting reliability of the springs, especially in a compressed state of the springs, and to avoid torsion spring deformation, in this example, a first spring mounting slot is provided on each of the first spring support portions, and the length directions of the first spring mounting slots are parallel to the sliding directions of the sliding blocks. In this example, the first spring support portions are two strip-shaped bulges disposed in parallel, and the length directions of the strip-shaped bulges are parallel to the sliding directions of the sliding blocks. First mounting slots for mounting the springs are formed between the two strip-shaped bulges. One ends of the springs are sleeved inside the first mounting slots, and the other ends thereof are sleeved outside the spring mounting columns of the sliding blocks. The spring mounting columns are columnar bulges, which are convenient for assembly, and improve the mounting stability and reliability of the springs.
In this example, the at least two elastic components are disposed on each sliding block, which can improve the supporting force and the stability of the support.
Pull cords 5 are disposed at tails of the sliding blocks 4, and are used for pulling the sliding blocks 4 to move inward so as to make the clamping portions 41 move inward into the mounting cavity and further allow same to be separated from the mop cloth, thus realizing automatic mop cloth dismounting. The pull cords 5 are brake cables, and operating ends of the pull cords 5 extend into the mop rod 1 and are connected to an operating portion on the mop rod 1. Connecting portions 51 at tails of the pull cords are sleeved inside slot bodies 42 of the sliding blocks to realize a connection. Furthermore, wire slots are also provided on the sliding blocks to allow the pull cords to pass through, which improves the overall connection reliability and stability.
In addition, the present disclosure further includes a mop base 3 for automatic mop cloth mounting. Specifically, a top of the mop base 3 is provided with a mounting hole 30, and the mounting hole 30 can accommodate the mop head to be just inserted and realize the mop cloth mounting. First limiting portions 31 are disposed on a side wall of the mounting hole, and second limiting portions 22 corresponding to the first limiting portions 31 are disposed on a side wall of the mop head 2. When the mop head is inserted into the mounting hole 30, the first and second limiting portions realize automatic limiting so as to control the mop head 2 to be mounted in the mounting hole in a centering manner, so that each of both ends of the mop head forms a certain interstice with the side wall of the mounting hole 30, which is used to allow the corresponding clamping portion to protrude and clamp same at an edge of the mop cloth located in the mounting hole, thus achieving the automatic mop cloth mounting. In this example, the first limiting portions 31 are limit slots formed on both sides of the mounting hole, and the second limiting portions 22 are limit bulges disposed on both sides of the mop head 2.
According to the quick mop cloth replacement mechanism provided by the present disclosure, since sliding block type clamping structures are disposed at both ends of the mop head, the quick mounting and dismounting between the mop head and the mop cloth is realized in a telescoping manner, so that the mechanism is convenient and labor-saving in mounting and dismounting, and good in user experience; due to arrangement of the elastic components, the mechanism is compact in structure and small in mounting space; pull cord structures are disposed for pulling the sliding blocks to move inward to realize quick mop cloth dismounting, so that the mechanism is simple and labor-saving in operation, and low in cost; and therefore, the quick mop cloth replacement mechanism provided by the present disclosure is compact in structure, has a good-looking appearance, can realize quick mop cloth mounting and dismounting, and is simple and labor-saving in operation, thus being good in user experience.
The above description is only a preferred implementation of the present disclosure, and it should be noted that, for those of ordinary skill in the art, several improvements and polishing can be made without departing from the technical principle of the present disclosure, and these improvements and polishing should also be regarded as the protection scope of the present disclosure.
