The there-necked flask specific brush that the utility model provides comprises fixed part, connecting rod rest and annular resilient brush, wherein, described connecting rod rest comprises at least 3 connecting rods, described connecting rod one end is fixed on described annular resilient and brushes, the other end is fixed on described fixed part, and described connecting rod is brushed from fixed part to annular resilient to be to radiate and arranged.
Preferably, the there-necked flask specific brush that the utility model provides also comprises holding assembly, and fixed part one side connects connecting rod, and opposite side connects described holding assembly.
Preferably, the there-necked flask specific brush that the utility model provides also comprises adjustable plate, and adjustable plate is provided with through hole, and described connecting rod passes described through hole.
Preferably, the there-necked flask specific brush that the utility model provides also comprises and pulls parts and pull bar, described fixed part and holding assembly are provided with passage, described pull bar passes the passage of fixed part and holding assembly, one end is connected with adjustable plate, the other end is connected with the described parts that pull, and pull bar can be done to come and go in passage and move.
The described parts that pull can be for ring-type or T-shaped bar or perpendicular to cross bar of pull bar etc.
Described holding assembly can be made by timber, rubber or plastic or other material.
Preferably, described annular resilient brush can be made ring spring by spring, has bristle on ring spring.
Preferably, described annular resilient brush can comprise elastic ring, and the ring body of elastic ring is built-in with at least one spring core, has bristle on the ring body outer surface of elastic ring.
Preferably, described connecting rod rest is made by steel wire, is obstructed if scrub, and also can manually with its bending, satisfy the demands.
The there-necked flask specific brush that the utility model provides can be by connecting rod rest expansion or tighten up, drive the annular resilient brush and open or dwindle, can effectively clean the circular arc glass apparatus, and can scratch instrument inwall, easy to use, simple in structure.
Description of drawings
Fig. 1 is the structural representation of the described there-necked flask specific brush of embodiment;
Fig. 2 is that the described there-necked flask specific brush of embodiment is used schematic diagram.
Reference numeral is: fixed part 1, and connecting rod rest 2, annular resilient brush 3, holding assembly 4, adjustable plate 5 pulls parts 6, pull bar 7, connecting rod 21, fixing hole 51, there-necked flask specific brush A, there-necked flask B.
The specific embodiment
With reference to the accompanying drawings, by specific embodiment, there-necked flask specific brush described in the utility model is described in detail and describes, understand the utility model with better, but should be understood that, following embodiment does not limit the scope of the invention.
The there-necked flask specific brush that the present embodiment provides comprises fixed part 1, connecting rod rest 2 and annular resilient brush 3, wherein, connecting rod rest 2 comprises at least 3 connecting rods 21, described connecting rod 21 1 ends are fixed on annular resilient brush 3, the other end is fixed on fixed part 1, connecting rod 21 is radial arranges, nearer apart from mutual distance at the first end of fixed part 1, far away at elastic annular 3 brush one end mutual distances.
Grasp connecting rod rest 2, connecting rod 21 spacings are reduced, connecting rod rest 2 shrinks, and shrinks thereby drive annular resilient brush 3.After decontroling connecting rod rest 2, under elastic reaction, annular resilient brush 3 shape that resiles.Therefore can regulate the size of annular resilient brush 3 and clean the purpose of the container of different-diameter with realization.
To achieve these goals, preferably, in the present embodiment, described annular resilient brush 3 comprises elastic ring, and the ring body of elastic ring is built-in with at least one spring core, has bristle on the ring body outer surface of elastic ring; Spring core can be elastic ring, makes elastic ring in rubber tube as elastic ring is placed in, and elastic ring is outside with bristle.
