Detailed Description

As shown in fig. 1-4, a brush head dismounting structure of a toilet brush comprises a handle 1 and a brush head connecting piece 2, wherein the brush head connecting piece 2 is provided with a brush head mounting part 3, and the brush head mounting part 3 is in a ball-shaped structure. The brush head connecting piece 2 is directly fixed with the end part of the brush head, the brush head connecting piece 2 is generally disc-shaped, and a ball-shaped brush head mounting part 3 is arranged on the brush head connecting piece for facilitating elastic clamping.

The toothbrush is characterized in that a pressing piece 4 assembled through elastic linkage is arranged at the upper end of the handle 1, a connecting rod is arranged in the handle 1, an installation piece 5 used for installing a toothbrush head is arranged at the lower end of the connecting rod, and the installation piece 5 and the lower end of the connecting rod are assembled through elastic linkage. And return springs 6 are arranged between the pressing piece 4 and the connecting rod and between the mounting piece 5 and the connecting rod. The pressing member 4 may be a button substantially, and is operated by pressing a member such as a driving link. The pressing piece 4 is restored to the original position through the return spring 6, and the connecting rod is restored through the return spring 6 at the lower end of the handle 1.

The installed part 5 has the bayonet socket that is used for the first installation department 3 of elasticity block brush, still be equipped with in the handle 1 and be used for restricting the open retaining member 7 of bayonet socket elasticity, the connecting rod lower extreme is equipped with and is used for pushing away the first installation department 3 of brush from the ejector pin 8 of the 5 bayonet sockets of installed part. The bayonet socket has certain elasticity restoring force can, and the first installation department of brush 3 pushes the back elasticity joint spacing. The locking piece 7 prevents the brush head mounting part 3 from being separated from the bayonet at will. Because there is some displacement of the mounting member 5 when in the disassembled or unlocked state, the locking member 7 need not be moved, and is typically a fixed assembly.

Correspondingly, installed part 5 is equipped with and supplies ejector pin 8 to get into and contact the jack 9 of first installation department 3 of brush, when pressing 4 pushes down, the connecting rod with pressing 4 linkage, the ejector pin 8 of connecting rod inserts in the jack 9 of installed part 5, the connecting rod drives installed part 5 and brush first installation department 3 and removes elasticity for retaining member 7 motion until the bayonet socket of installed part 5 and open the restriction, the ejector pin 8 of connecting rod pushes away first installation department 3 of brush from the bayonet socket of installed part 5 this moment. The ejector rod 8 can assist the brush head mounting part 3 to separate from the bayonet faster, more stably and more conveniently.

The installed part 5 is the cylindric structure that the central authorities link up, be equipped with between brush installation department 3 and the brush head connecting piece 2 and be in the terminal annular 10 of elasticity block, jack 9 has the cooperation portion that suits with brush installation department 3 shape. Simple structure even installed part 5 damages after using a period, also only need to change the widget can, can give the user and be equipped with some spare parts more usually. After the matching part is convenient to elastically clamp, the volume of the mounting part 5 is not obviously changed.

The connecting rod comprises an upper rod 11 and a lower rod 12, and the upper rod 11 is connected with the lower rod 12 in a socket-and-spigot manner. Make things convenient for handle 1 to be the design structure of arc line shape, go up pole 11 and lower beam 12 and have the space of relative activity, both break away from slightly and can adapt to the cavity that is the pitch arc, satisfy multiple use or design condition.

The handle 1 is internally provided with a cavity for mounting parts, the cavity is provided with a rib plate 14 and a locking groove 13 formed by the rib plate 14 in a separated manner, and the locking piece 7 is arranged in the locking groove 13. The movement of the locking element 7 is almost completely restricted by the design of the locking groove 13.

The cavity is provided with a limiting plate 15 below the locking groove 13 for preventing the mounting piece 5 from being separated from the handle 1.

The cross-section of the upper rod 11 and the lower rod 12 along the length direction is in a cross shape, and a plurality of reinforcing ribs 16 are arranged on the upper rod 11 and the lower rod 12 along the length direction. The strength of the structure is increased, the service life of parts is prolonged, and the handle is suitable for the longer service condition of the handle 1.

One end of the upper rod 11, which is far away from the lower rod 12, is provided with a stop ring 17 and a reinforcing ring 18, and the reinforcing ring 18 is adjacent to the top rod 8. The upper rod 11 or the lower rod 12 is prevented from being separated from the handle 1, and the diameter difference between the outer ring and the inner ring of the reinforcing ring 18 on the lower rod 12 is large, namely the thickness is large, so that the structural strength of the joint of the ejector rod 8 is enhanced.

A plurality of guide pieces 19 for limiting the swinging of the connecting rod are arranged in the cavity, and a sector groove 20 matched with the connecting rod is arranged at the outer edge of each guide piece 19. The guide piece 19 can reduce the clamping of the assembly and disassembly, the shaking of the connecting rod during the use and the like.

Handle 1 includes casing assembly and casing assembly down, goes up casing assembly and cup joints fixedly down between the casing assembly, it includes upper left casing 21 and upper right casing 22 to go up casing assembly, casing assembly includes casing 23 and casing 24 down on a left side down. Easy to assemble with dismantle completely, reduce and accomodate and carry space etc..

Brief description of the use principle: the pressing piece 4 is pressed downwards, and the pressing piece 4 compresses the return spring 6 and drives the connecting rod to move downwards; a mandril 8 on the connecting rod is inserted into the mounting part 5, and the mandril 8 is then propped against the brush head mounting part 3; the mounting piece 5 and the brush head mounting part 3 move downwards along with the ejector rod 8 and the connecting rod, the mounting piece 5 is limited to move only in a short distance, the bayonet is gradually opened at the moment, and the brush head mounting part 3 can be separated.

In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like indicate the position or positional relationship based on the position or positional relationship shown in the drawings, and are only for convenience of description, and are not intended to indicate or imply that the device or element referred to must have a specific position, be constructed and operated in a specific orientation, and therefore, are not to be considered as limitations of the present invention, and the fundamental principles, main features, and advantages of the present invention have been shown and described above, as would be understood by those skilled in the art.
