Description

Technical Field

[0001] This utility model relates to a rainproof coupling and belongs to the field of power tool technology. Background Technology

[0002] During the use of cleaning tools, if water seeps in, it can enter the equipment through gaps and cause a short circuit. A short circuit not only causes the equipment to suddenly stop working, affecting cleaning efficiency, but it can also severely damage core components such as the control board, increasing maintenance costs and the equipment's failure rate.

[0003] Traditional electric brushes typically employ an axial insertion design, with external rubber sealing the coupling of the scrubbing head or handle. While this design can meet waterproofing requirements to some extent, ensuring normal operation in humid environments, its drawbacks are also significant. The large number of components complicates the overall structure, increases production costs and maintenance difficulty, and hinders product modularization. Utility Model Content

[0004] The purpose of this invention is to overcome the problems existing in the prior art and provide a rainproof coupling with a waterproof rating of X IP4, which meets the waterproof requirements of cleaning tools such as electric brushes under the conditions of use, and is inexpensive and easy to install.

[0005] To solve the above technical problems, this utility model provides a rainproof coupling, comprising: a first connecting member and a second connecting member, wherein the first connecting member and the second connecting member are provided with mutually cooperating locking components, characterized in that: the first connecting member and the second connecting member are respectively provided with radially insertable insert terminals, the insert terminals are inserted into insert protective seats, the protective seat cover plate covers the opening of the insert protective seat, the protective seat cover plate and the insert protective seat are fixed to the first connecting member and the second connecting member by a stop, and the insert protective seat and the protective seat cover plate are provided with water guiding channels for water flow on their exterior.

[0006] Furthermore, one end of the first connector and the second connector is provided with a matching elastic locking element, and the other end is provided with a locking buckle.

[0007] Furthermore, the outer wall of the insert protection seat is provided with a water channel in the radial direction, and the two sides of the water channel are provided with limiting ribs. The stop behind the elastic locking member is engaged with the limiting rib and forms a drainage hole.

[0008] Furthermore, the protective cover plate covers the insert protective seat through a stepped stop, and the protective cover plate abuts against the step of the stepped stop.

[0009] Furthermore, the first connector and the second connector are respectively provided with inwardly bent guide grooves and outwardly bent socket ribs on both sides along the insertion direction, and the guide grooves and socket ribs are interlocked with each other.

[0010] Furthermore, the guide groove and the joint of the reinforcing bar form a backward-sloping water-falling slope.

[0011] Furthermore, the front end of the first connector is provided with a positioning protrusion, and the front end of the second connector is provided with a concave hole that matches the positioning protrusion.

[0012] Compared with the prior art, the present invention has achieved the following beneficial effects: by designing the shape of the stop and the insert protection seat, the water flow avoids the electrical components and flows to the outside of the coupling housing. Attached Figure Description

Detailed Implementation

[0020] In the following description of this utility model, the terms "upper", "lower", "front", "rear", "left", "right", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not mean that the device must have a specific orientation.

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0023] like Figure 1 and Figure 2 As shown, this utility model aims to provide a rainproof coupling, including: a first connecting member 1 and a second connecting member 2, the first connecting member 1 and the second connecting member 2 being radially inserted, the first connecting member 1 and the second connecting member 2 being provided with mutually cooperating locking components, the first connecting member 1 and the second connecting member 2 being respectively provided with radially inserted insert terminals 3, the insert terminals 3 being inserted into insert protective seats 4, the protective seat cover plate 5 covering the opening of the insert protective seat 4, the protective seat cover plate 5 and the insert protective seat 4 being fixed to the first connecting member 1 and the second connecting member 2 by a stop, and the outside of the insert protective seat 4 and the protective seat cover plate 5 being provided with a water guiding channel for water flow.

[0024] like Figure 3 and Figure 4 As shown, one end of the first connector and the second connector is provided with a matching elastic locking member 6, and the other end is provided with a locking buckle 7.

[0025] The outer wall of the insert protection seat 4 is provided with a water channel 8 in the radial direction. The water channel 8 is provided with limiting ribs 9 on both sides. The stop behind the elastic locking member 6 is engaged with the limiting ribs 9 and forms a water drop trough 10.

[0026] like Figure 5 As shown, the protective cover plate 5 covers the insert protective seat 4 through the stepped stop 11, and the protective cover plate 5 abuts against the step of the stepped stop 11.

[0027] The first connector 1 and the second connector 2 are respectively provided with an inwardly bent guide groove 14 and an outwardly bent socket rib 15 on both sides along the insertion direction. The first connector 1 has a positioning protrusion 12 at the front end, and the second connector 2 has a concave hole 13 at the front end that matches the positioning protrusion 12.

[0028] The guide groove 14 and the socket rib 15 form a backward-sloping drainage slope 16 at their insertion points. When water seeps into the machine through the recessed hole 13 or other gaps in the coupling, part of it flows out of the machine through the drainage trough 10 and the water guide trough 8, and part of it flows out of the machine through the stepped stop 11. This avoids the water from contacting the insert terminal 3 and causing a short circuit, and also eliminates the need for rubber sealing of the external coupling housing, thus reducing costs and providing rain protection.

[0029] The above description is merely a preferred embodiment of the present utility model, showing and describing the basic principles, main features, and advantages of the present utility model. It is not intended to limit the scope of patent protection of the present utility model.
