Description

Technical Field

[0001] The utility model relates to the field of mop accessories, and particularly relates to a durable dust mop frame. Background Art

[0002] A mop, also known as a swab, refers to a long-handled cleaning tool for scrubbing the ground, and also generally refers to a long-handled cleaning tool, which is mainly used to dip an appropriate amount of water to dissolve and wipe off the dirt on the ground. Most of the cleaning sleeves of the current mop heads are provided with a fixed dust mop frame. The dust mop frame includes a metal ring and two vertical connecting pieces located inside the metal ring. The metal ring is integrally bent and welded from metal steel bars. In the actual use process, users find that the stress at the welding point of the metal ring is relatively large, and the diameter of the steel bar itself is not very thick. Therefore, the welding point is prone to dislocation and fracture during use. In addition, since the vertical connecting piece has a vertical sheet structure, the vertical connecting piece is prone to rotate and disconnect relative to the metal ring when stressed from the side, resulting in unstable connection between the vertical connecting piece and the metal ring.

[0003] Although our unit disclosed a mop head in the application No. 2015207990411 in 2015, which includes a cleaning sleeve, the cleaning sleeve is provided with a cleaning member, the inner cavity of the cleaning sleeve is provided with a fixing ring (the dust mop frame described in this article) for supporting the cleaning sleeve, the cleaning sleeve includes an inlet part for the fixing ring to be put in or taken out, and the inlet part includes an upper piece and a lower piece which are detachably connected and correspondingly arranged for opening and closing the inlet part. And it shows the structure of the dust mop frame in the attached Figure 4 drawing of its specification, but this dust mop frame structure cannot solve the above technical problems at the same time. However, the connecting column of the dust mop frame is arranged at the upper middle position between the two vertical connecting pieces, which is not convenient for the installation and use of the mop rod. In addition, the fixing of the first welding point of the metal ring cannot be achieved. Content of the Utility Model

[0004] In order to solve the above problems, the utility model provides a durable dust mop frame:

[0005] A durable dust mop frame includes a metal ring, two vertical connecting pieces, and a connecting unit. The main body of the metal ring includes a first connecting rod, a second connecting rod, and two arc-shaped connecting parts which are integrally connected. The two arc-shaped connecting parts respectively connect the ends of the first connecting rod and the second connecting rod, and the first connecting rod is provided with a first welding point for welding the metal ring;

[0006] The vertical connecting piece has a triangular, inverted V-shaped or semi-circular arc structure, and the vertical connecting piece is provided with a connecting hole for connecting the mop rod;

[0007] The connecting unit includes a first connecting column. The two ends of the first connecting column are respectively fixedly connected to the opposite inner sides of two vertical connecting pieces. The two end faces of the first connecting column are fixedly attached to the vertical connecting pieces. The two ends of the first connecting column are respectively fixedly connected to the outer sides of the bottoms of the two vertical connecting pieces. The first connecting column can provide a supporting force for the vertical connecting pieces. A first connecting rod is fixedly connected to the side of the first connecting column. There are a plurality of fixed connection points between the first connecting column and the first connecting rod, and the plurality of fixed connection points are distributed on both sides of the first welding point.

[0008] Preferably, strip-shaped fixing parts with integral extensions are provided at the outer ends of the two outer sides of the bottom of the vertical connecting piece. The strip-shaped fixing parts of the two different vertical connecting pieces extend away from each other. The strip-shaped fixing part is fixedly connected to the first connecting rod or the second connecting rod, and the strip-shaped fixing part is used to provide a corresponding supporting force for the vertical connecting piece. The fixed connection between the strip-shaped fixing part and the first connecting rod or the second connecting rod has good stability. The strip-shaped fixing part is used to provide a corresponding supporting force for the vertical connecting piece to prevent the two vertical connecting pieces from turning outwards away from each other.

[0009] Preferably, there are two fixed connection points between the first connecting column and the first connecting rod. The two fixed connection points are respectively located on both sides of the first welding point. The first connecting column and the first connecting rod are fixedly connected by welding.

[0010] Preferably, the vertical connecting piece has an inverted V-shaped structure. The two upper outer edges and the bottom outer edge of the vertical connecting piece form an isosceles triangle structure. A triangular notch is provided in the middle of the bottom of the vertical connecting piece, and the two side edges of the triangular notch are parallel to the two upper outer edges of the vertical connecting piece. The vertical connecting piece in this application is equivalent to opening an isosceles triangle notch with the same proportion at the bottom of the isosceles triangle, so that on the basis of not affecting the mechanical structure of the vertical connecting piece, the weight of the vertical connecting piece is reduced, the material cost is lowered, and the aesthetic degree of the product is improved.

[0011] Preferably, the connecting unit further includes a second connecting column corresponding to the first connecting column. The second connecting column is symmetrically arranged relative to the first connecting column. The two ends of the second connecting column are fixedly connected to the outer sides of the bottoms of the two vertical connecting pieces, and a second connecting rod is fixedly connected to the side of the second connecting column.

[0012] Preferably, the fixed connection method of the first connecting column and the second connecting column to the metal ring is welding, and the diameters of the first connecting column and the second connecting column are the same as the diameter of the metal ring. The diameters of the first connecting column and the second connecting column being the same as the diameter of the metal ring can make the connection force between the connecting column and the connecting rod more stable, and also improve the supporting force of the connecting column on the vertical connecting piece.

[0013] Preferably, the connecting unit further includes two support pins that are detachably and symmetrically arranged. There are two symmetrically arranged track grooves in a straight notch shape at the waist positions on the opposite sides of the vertical connecting piece. The corresponding track grooves of two different vertical connecting pieces form a sliding cavity that fits the support pins. The two track grooves of the same vertical connecting piece extend obliquely downward. The vertical connecting piece is provided with a socket communicating with the sliding groove, and the socket fits the support pin. First, the structures of the track groove and the socket further reduce the material loss and lighten the weight of the finished product. Second, the support pins in this application can further provide corresponding support forces for the two vertical connecting pieces to prevent the vertical connecting pieces from tipping over and breaking.

[0014] Beneficial effects: The first connecting column provided in this application has two functions: First, by fixedly connecting the sides of the two vertical connecting pieces, it provides corresponding support forces for the two vertical connecting pieces to prevent the two vertical connecting pieces from tipping over and breaking relatively; Second, there are multiple fixed connection points between the first connecting column and the first connecting rod. The multiple fixed connection points are distributed on both sides of the first welding point, so that there is a corresponding fixing force between the first connecting column and the first connecting rod, improving the stability of the metal ring and preventing the metal ring from breaking at the first welding point, significantly improving the durability.
