Description

Technical Field

[0001] This utility model relates to the field of vacuum cleaner manufacturing technology, and in particular to a charging base bracket buckle structure. Background Technology

[0002] Among existing vacuum cleaners, handheld vacuum cleaners are gradually gaining popularity in home and car applications due to their small size and ease of use. In particular, battery-powered cordless handheld vacuum cleaners are free from the limitations of cord length and can flexibly clean every corner. Existing charging devices are generally divided into two types: pedestal charging devices and wall-mounted charging devices. The pedestal charging structure connects the upper bracket to the lower base so that the base supports the bracket and prevents it from tipping over.

[0003] Chinese Patent Authorization Announcement No.: CN 108599338 A, Authorization Announcement Date: September 28, 2018. This utility model proposes a vacuum cleaner charging rack and vacuuming system, relating to the field of household appliance technology, to solve the problem that vacuum cleaners cannot charge their backup batteries independently during charging. The vacuum cleaner charging rack includes: a charging mechanism, a support column, and a base. The charging mechanism includes: a main unit charging section for charging the main unit of the vacuum cleaner, and a battery compartment for charging the battery. The support column connects the charging mechanism and the base. The base includes an upper shell, a counterweight plate, and a lower shell. The top surface of the upper shell is an inclined surface, and the angle of inclination of the inclined surface is equal to the angle of inclination of the bottom surface of the vacuum cleaner brush. The counterweight plate is located between the upper shell and the lower shell. The shortcomings of this technical solution are: the top of the support column (bracket) is inserted into a limiting sleeve for fixing to the base, which makes it easy to pull out and separate the structure, and the connection strength between the structures is low, making it easy to tip over.

[0004] In summary, the charging stand bracket has shortcomings in terms of assembly strength and stability. Utility Model Content

[0005] The present invention aims to overcome the shortcomings of poor assembly stability in existing charging dock brackets by providing a charging dock bracket snap-fit ​​structure that enhances the structural assembly strength and stability.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A charging dock bracket snap-fit ​​structure, including The base has a mounting groove, which is connected to a fastening seat. There is a cavity gap between the fastening seat and the groove wall of the mounting groove. The vertical central axes of the upper and lower cavities of the cavity gap do not coincide. The fastening seat has a hollow structure and a reinforcing plate is connected inside the fastening seat. The socket is inserted into the fastening groove. The upper end of the socket is interference-fitted with one side of the upper end of the fastening groove, and the lower end of the socket is interference-fitted with the other side of the lower end of the fastening groove. The socket is connected to a bracket. The buckle plate connects to the socket, and the mounting groove has a snap-fit ​​groove, which is engaged with the buckle plate. Fastening strip, fastening strip is connected to fastening seat, fastening seat abuts against the inner wall of socket; The plug is connected to the outside of the socket and abuts against the wall of the mounting groove.

[0007] The bracket is fixed to the base via a socket and a fastening slot. The socket has a hollow internal structure. The fastening seat is inserted into the socket to support it from the inside. Simultaneously, after the socket is inserted into the fastening slot, the upper and lower parts of the socket are compressed simultaneously, achieving an interference fit with opposite compression directions. This ensures the socket is fully clamped from both top and bottom. Fastening strips are connected to two opposite sides of the socket. The fastening strips apply force from the inside of the socket, while the insert is subjected to the reaction force from the fastening slot, thus applying force from the outside of the socket. This achieves internal and external clamping of the socket and improves the stability of the connection between the bracket and the base. The snap plate is inserted and engages with the snap groove of the fastening slot to further secure the socket. The fastening seat has a hollow structure to allow for springback under stress, preventing the snap plate from breaking. A reinforcing plate increases the strength of the fastening seat and prevents it from breaking under stress. This design achieves the effects of quick and stable assembly of the bracket and base via snap-fit, simplifying assembly without screws, improving assembly efficiency, protecting the structure, and extending service life.

[0008] Preferably, the snap-on panel includes a connecting plate and a snap-on strip. The socket has a mounting opening, one end of the connecting plate connects to the mounting opening, and the other end connects to the snap-on strip. The connecting plate, socket, and snap-on strip form an integrated structure to improve the overall structural strength. Simultaneously, by placing the snap-on panel at the mounting opening, the snap-on strip is subjected to the counter-thrust force of the fastening groove, allowing for slight deformation to accommodate assembly movement and prevent structural breakage. This achieves the effect of improving structural strength and protecting the structure from breakage.

[0009] Preferably, the end face of the fastener strip is provided with a guide bevel, and the opening of the fastening groove is slidably connected to the guide bevel. The end face of the fastener strip is quickly inserted into the opening of the fastening groove through the obliquely arranged bevel, achieving the effect of rapid and smooth assembly of the structure.

[0010] Preferably, the outer side of the socket has a recessed guide surface. The upper end of the outer side of the socket abuts against the inner wall of the fastening groove, while the recessed guide surface is located at the lower end of the outer side of the socket and does not abut against the inner wall of the fastening groove. The recessed guide surface allows the lower end of the socket to be quickly inserted into the thicker fastening groove, thus guiding the upper end of the socket to be forcefully inserted between the fastening seat and the groove wall for installation. This improves the smoothness and stability of assembly.

[0011] Preferably, the upper outer surface of the fastening base is provided with a second guide slope, and the inner side of the socket is slidably connected to the second guide slope, with the inner side of the socket abutting against the outer surface of the fastening base. During assembly, the socket is guided along the second guide slope into the fastening groove and then tightened. This improves the smoothness and efficiency of assembly.

[0012] Preferably, the end face of the fastening strip is provided with a guide slope three, and the fastening strip is slidably connected to the guide slope three. When the fastening strip enters the fastening groove, it is guided into the fastening groove along the guide slope three of the fastening strip for fastening. This achieves the effect of improving assembly smoothness and efficiency.

[0013] Preferably, the lower outer surface of the fastening base has a protruding clamping surface, and the lower inner surface of the socket abuts against the protruding clamping surface. The upper outer surface of the socket abuts tightly against the groove surface of the fastening groove, and the lower end abuts tightly against the protruding clamping surface after insertion. Through the lever principle, the tightness of the socket connection is further enhanced, thereby improving the reliability of the assembly.

[0014] The beneficial effects of this utility model are: it enables quick and stable assembly of the bracket and base through snap-fit ​​connection; it simplifies assembly operations by eliminating the need for screws, thereby improving assembly efficiency; it protects the structure and extends its service life; it improves structural strength and protects the structure from breakage; it enhances assembly smoothness; and it improves assembly reliability.
