Description

Technical Field

[0001] This utility model relates to a hose reel used in automobile maintenance, repair, cleaning and other work, specifically a general-purpose hose reel housing structure. Background Technology

[0002] A hose reel, also known as a cable winder or drum, is a device primarily used for conveying various media such as water, gas, and oil. With a hose reel, workers can easily and quickly obtain various energy materials or tools. When in use, the hose is pulled to the required length for operation, and then automatically wound back up. This design avoids the accumulation and haphazard placement of hoses on the ground, reduces safety hazards, and improves work efficiency. Hose reels are widely used in factory workshops, 4S car dealerships, car detailing shops, and other workplaces requiring car repair, maintenance, and car washing.

[0003] Hose reels are generally classified into five types based on their application and the type of tubing or wire used: water-operated, pneumatic, electric, dual-tube, and high-pressure. The basic structure of hose reels is largely the same, typically including a left housing, right housing, central shaft, drum, left and right reels, and coil springs. However, depending on the size of the reels and the length of the central shaft, they are generally categorized into large drum and small drum types. Dual-tube and high-pressure reels have larger reel diameters, wider tubing winding widths, and longer central shafts; while water-operated, pneumatic, and electric reels have smaller reel diameters and shorter central shafts. Existing technology often manufactures two different sets of housings for large and small drum hose reels, requiring two different molds. However, the housing shape and size of large and small drum hose reels are essentially the same. Therefore, requiring two different molds and housings due to variations in internal structure is wasteful, labor-intensive, and wasteful of materials. Therefore, it is necessary to develop a universal hose reel housing structure that can be used for both large and small drums to avoid waste.

[0004] Below is the prior art document most closely related to the technical solution of this application, which we found through a novelty search: CN201320278943.1; "Automatic Tube Winder". This document discloses an automatic tube winder, including a central shaft, a drum fixed between a left housing and a right housing, a tube wound around the outer end of the drum, reels on both sides of the drum, and a coil spring inside the drum. The central shaft is fixedly connected to the left housing by fasteners. The inner end of the coil spring is connected to a rotating shaft, and the outer end of the coil spring is fixedly connected to the inner end face of the drum. One end of the rotating shaft is connected to the central shaft via a bushing, and the other end is linked to a pressure adjusting cover on the outer end face of the right housing via fasteners. A self-locking pawl is provided on the inner end face of the left housing, and a self-locking pawl with internal teeth that can mesh with the self-locking pawl is provided on the left reel of the drum. The main purpose of this utility model is to provide an automatic tube winder that is convenient for users and allows for easy adjustment of the coil spring's winding force via a pressure adjusting cover.

[0005] After analysis, we believe that the technical solution still has shortcomings and needs to be improved: the outer shell of the product is not universal. In actual use, it is still necessary to make two sets of outer shells according to the difference between the large drum and the small drum (reel size, central shaft length). Two sets of molds have been developed, which still cannot avoid material waste and labor waste (working hours, labor intensity of workers). Utility Model Content

[0006] The technical objective of this utility model is to provide a novel design for a universal hose reel shell structure. This shell structure can be assembled into both large and small drum hose reels. Therefore, in actual manufacturing, only one set of shells needs to be made and one set of molds needs to be developed, which can be used for both large and small drum hose reels. This achieves labor and material savings, reduces waste, and improves work efficiency and production benefits.

[0007] The technical solution of this utility model is as follows: This utility model provides a universal hose reel shell structure, which includes a front shell and a rear shell. Side frames that are separately assembled with the shell are provided on both sides between the front and rear shells. Symmetrical front and rear assembly windows are respectively opened at the center of the front and rear shells. Inner and outer mounting slots are respectively provided on the inner and outer sides of each assembly window. Front and rear assembly plates are provided corresponding to the front and rear assembly windows. The front and rear assembly plates can be installed on the outer mounting slots or inner mounting slots of the corresponding assembly windows according to the assembly requirements. Correspondingly, central shaft assembly holes, accessory assembly holes, and mounting holes are provided on the front and rear assembly windows. Protective covers that can cover the front and rear assembly windows are respectively provided on the outer sides of the front and rear shells.

[0008] Furthermore, the interval between the inner and outer mounting slots of this utility model is set according to actual processing needs, including the setting of the shell thickness and the assembly plate thickness.

[0009] Furthermore, the side frame of this utility model is set as an integral structure, or as a split structure including a left side frame and a right side frame that are symmetrical.

[0010] Furthermore, this utility model provides reinforcing rib structures on the front or rear of the front and rear assembly plates.

[0011] Furthermore, this utility model provides a shaped reinforcing rib structure on the outside of the accessory assembly holes of the front and rear assembly plates, which serves both a strengthening and aesthetic purpose.

[0012] Furthermore, the front of the protective cover of this utility model can be provided as a transparent observation window.

[0013] The working principle of this utility model is as follows: When a large drum hose reel needs to be assembled in the use of the universal shell structure described in this utility model, the front and rear assembly plates are installed on the outer mounting slots of the assembly windows on the front and rear shells respectively. In this way, the shell has sufficient front and rear space, so a longer central axis can be used, and the whole product is assembled into a large drum hose reel. When a small drum hose reel needs to be assembled, the front and rear assembly plates are installed on the inner mounting slots of the assembly windows on the front and rear shells. In this way, the shell becomes narrower front and rear, and a shorter central axis is used, and the whole product is assembled into a small drum hose reel.

[0014] The beneficial effects of this utility model are as follows: The hose reel described in this utility model has excellent versatility and practicality. In actual manufacturing, only one set of molds needs to be developed. The manufactured shell can be assembled into both large-drum and small-drum hose reels according to actual needs, saving labor and materials, reducing waste, and improving work efficiency and production benefits. The technical concept of this utility model can be applied to all similar hose reel products, and has broad prospects and promotional significance.

[0015] Meanwhile, this utility model features a protective cover on the outside of the assembly window, providing dust and splash protection while also offering a pleasing aesthetic appeal. Reinforcing ribs are provided on the front and rear assembly plates, either at the front or rear, to enhance the strength and toughness of the assembly plate structure. These reinforcing ribs also serve a positioning function. The design of each structure in this utility model strives for simplicity while ensuring sufficient functionality and practicality.
