Description

Technical Field

[0001] This utility model belongs to the technical field of kitchen and bathroom accessories, specifically relating to a connection structure for kitchen and bathroom accessories. Background Technology

[0002] Kitchen and bathroom toilet paper holders are common kitchen and bathroom accessories, and their installation stability and convenience are crucial. Nowadays, consumers have increasingly higher demands for these hardware accessories, placing greater emphasis on the reliability and durability of the installation structure in addition to appearance.

[0003] The existing perforated toilet paper holder installation structure has obvious defects. Cutting an arc-shaped section from a single tube and welding it to the corresponding connecting tube results in unsightly welds, requires specialized technology and equipment, and leads to high production costs. Alternatively, a single piece with a screw assembly made entirely of plastic is cheaper, but lacks strength and is easily damaged. Another option is plastic with screws, but only iron screws (magnetically attracted) can be used to fit into the injection mold. This provides sufficient strength, but stainless steel screws cannot be used (as they require magnetic attachment to the mold), and each screw must be inserted manually, resulting in low efficiency, high cost, and poor sealing between the mold and screws, often leading to glue leakage and defective products. Utility Model Content

[0004] To overcome the shortcomings of existing technologies and solve the problems of easy glue bursting and poor stability in the installation structure of kitchen and bathroom accessories, this utility model proposes a connection structure for kitchen and bathroom accessories.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A connection structure for kitchen and bathroom accessories includes:

[0007] The docking assembly includes docking tube I and docking tube II. Docking tube I is a circular tube structure with axial openings on the side walls, and docking tube II is a complete circular tube structure with a pre-set nut on the inner wall.

[0008] The fixing component includes an external hexagonal screw and a connector with an external hexagonal slot. The head of the external hexagonal screw is embedded in the external hexagonal slot, and the screw end of the external hexagonal screw passes through the axial opening of the connecting pipe I and is threadedly locked with the nut on the connecting pipe II.

[0009] This utility model's installation structure achieves stable assembly and convenient installation of the paper roll holder through the cooperation of docking components and fixing components, combining multiple benefits such as structural stability, efficient installation, and controllable cost.

[0010] Preferably, the inner wall shape of the external hexagonal slot is perfectly matched with the head shape of the external hexagonal screw to limit the external hexagonal screw from rotating during assembly. The perfect fit between the external hexagonal slot and the screw head effectively limits the screw's rotation, improving assembly convenience and efficiency.

[0011] Preferably, the inner wall of the connecting pipe II and the nut are interference fit, and the thread specification of the nut is the same as the thread specification of the screw end of the external hexagonal screw. The interference fit and thread matching between the nut and the connecting pipe II ensure a stable connection and avoid assembly misalignment and loosening during use.

[0012] Preferably, the connector and the wall mounting base of the toilet paper holder are integrally formed, which enhances the structural strength and simplifies the assembly process.

[0013] Preferably, the plug end on the connector is inserted into the axial opening of the coupling tube I, and the limiting plate on the connector is limited to the outside of the coupling tube I. The plug end of the connector is adapted to the opening of the coupling tube I and the limiting plate is limited to the outside, which can realize the precise docking of the components and effectively prevent excessive displacement of the coupling tube I during assembly.

[0014] Preferably, the connecting pipe I and connecting pipe II are tightened with hexagonal screws and nuts to form a bracket.

[0015] Compared with the prior art, the technical effects and advantages of this utility model are:

[0016] (1) This utility model restricts the screw rotation by precisely fitting the external hexagonal slot with the screw head. With the scientific component matching design, assembly can be completed without complicated operation, which significantly improves the convenience and efficiency of installation. Ordinary users can also easily get started.

[0017] (2) The interference fit between the nut and the connecting pipe II in this utility model ensures a stable connection, and the integrated molding design of the connecting pipe II and the bracket and other key components enhances the overall strength.

[0018] (3) While ensuring performance, this utility model reduces the cost of production and use by simplifying the assembly process and adopting highly adaptable materials and structural designs. It solves many problems of traditional structures and takes into account the need for lightweighting, thus achieving a balance between performance and economy. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] This utility model discloses a connection structure for kitchen and bathroom hanging accessories, specifically designed for toilet paper holders 10 in bathrooms or kitchens. Its core lies in achieving stable assembly and convenient installation of the toilet paper holder 10 through precise cooperation between the connecting components and the fixing components. The following description, in conjunction with the attached... Figures 1 to 4 This application will provide a further detailed description of the relationship between the various components.

[0026] This kitchen and bathroom accessory installation structure comprises two core parts: a connecting component and a fixing component. The connecting component consists of connecting pipe I1 and connecting pipe II2, while the fixing component includes an external hexagonal screw 4 and a connector 6 with an external hexagonal slot 5. During the factory assembly stage, connecting pipe II2 is a complete circular tube structure, and its inner wall is fixed to the nut 3 by an interference fit, ensuring that the nut 3 will not shift during assembly and use. Furthermore, the thread specification of the nut 3 is pre-matched to the thread specification of the screw end 8 of the external hexagonal screw 4.

[0027] As a key component connecting the wall and the docking assembly, the connector 6 is structurally designed to fully meet installation requirements: The connector 6 has an integrally formed external hexagonal slot 5, the inner wall shape of which perfectly matches the head 7 of the external hexagonal screw 4, preventing the external hexagonal screw 4 from rotating during assembly; a guide channel 9 is connected below the external hexagonal slot 5, the diameter of which matches the diameter of the screw end 8 of the external hexagonal screw 4, providing stable assembly guidance for the screw end 8. Simultaneously, an external threaded portion 13 is integrally formed at the end of the connector 6 away from the guide channel 9, and a circular limiting plate 15 is provided on one side of the external threaded portion 13. The diameter of the limiting plate 15 matches the diameter of the connecting pipe I1, forming a limiting structure during assembly.

[0028] The side wall of the connecting pipe I1 has an axial opening, the width of which is adapted to the width of the insertion end 14 of the connector 6, facilitating the insertion end 14 to be embedded and fixed. During actual installation, the wall mounting base 12 must be fixed first. The external thread 13 of the connector 6 is screwed into the wall mounting base 12 of the paper roll holder 10 until the limiting plate 15 is in contact with the surface of the wall mounting base 12, completing the pre-fixation of the connector 6. Then, the head 7 of the external hexagonal screw 4 is inserted into the external hexagonal slot 5 of the connector 6, allowing the screw end 8 to pass through the guide groove 9. The axial opening of the connecting pipe I1 is then aligned with the insertion end 14 of the connector 6 and inserted. At this time, the limiting plate 15 will limit the connection to the outside of the connecting pipe I1, preventing excessive displacement of the connecting pipe I1.

[0029] After completing the above pre-assembly, align the free end of connector I1 with connector II2, and push the bracket 11 of the paper roll holder 10 so that connector II2 is connected to the outside of connector I1, ensuring that the screw end 8 of the external hexagonal screw 4 is aligned with the nut 3 inside connector II2. Connectors I and II form a bracket after being locked with the external hexagonal screw and nut.

[0030] Since the head 7 of the external hex screw 4 is limited by the external hex socket 5 and cannot rotate on its own, simply rotating the bracket 11 of the paper roll holder 10 will cause the connecting pipe II 2 and the internal nut 3 to rotate synchronously, so that the nut 3 and the screw end 8 of the external hex screw 4 form a threaded lock. When the resistance increases significantly when rotating, all assembly steps are completed. At this time, the connecting pipe I 1 and the connecting pipe II 2 are tightly fitted, and the paper roll holder 10 is fixed to the wall by a stable installation structure.

[0031] In this embodiment, the limiting fit between the external hexagonal screw 4 and the external hexagonal slot 5, along with the threaded locking of the nut 3, simplifies the installation operation and avoids problems such as glue bursting and stripping in traditional structures. The entire assembly process does not require special tools and can be completed by ordinary consumers, fully meeting the needs for convenient installation.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
