Description

Technical Field

[0001] This utility model belongs to the field of pipe reel installation design technology, and in particular relates to a wall fixing structure for a pipe reel. Background Technology

[0002] Hose reels, as simple tools for storing and winding water pipes, are widely used in homes, gardens, and property maintenance. For easy placement, they are typically mounted on walls or placed directly on the ground for easy mobility. For example, Chinese utility model patent application number 201980088307.2 discloses a design called a hose reel assembly. This design features a slot and a turntable at the bottom of the hose reel, with a base providing support for the slot. The hose reel rotates within the slot via the turntable, and the slot's engagement prevents it from coming undone.

[0003] However, the above solution has certain drawbacks in practical use. First, the rotating groove is not integrally formed on the support platform of the base. Instead, two half-grooves are formed on the support platform and a mounting component, respectively. The two half-grooves are then fixed together by the mounting component to form a complete rotating groove structure. Because this rotating groove is a split-combination structure, its overall strength is insufficient. When the hose reel is pulled and generates a large rotational torque, the rotating groove area is prone to cracking, and may even cause the mounting component to be pulled off the support platform. Second, the anti-detachment function of the above solution relies on the engagement of the inner shoulder on the top surface of the rotating groove with the hose reel's slot. However, both the support platform and the mounting component need to be equipped with corresponding rotating grooves and inner shoulders. Due to the limitations of product thickness and rotating groove depth, the inner shoulders are usually thin and have limited load-bearing capacity. When the hose reel is pulled and rotated during use, the inner shoulder is prone to breakage, causing the anti-detachment function to fail and the hose reel to fall off the base. In other words, the above structure has problems with insufficient strength and low reliability of anti-detachment, affecting the safety and stability of existing hose reel wall fixing structures. Utility Model Content

[0004] This utility model proposes a wall-mounted fixing structure for a hose reel to solve the problems mentioned in the background art, such as insufficient strength of the split-type rotating groove structure, limited load-bearing capacity of the anti-detachment shoulder, and the hose reel being prone to tearing or falling off under the action of rotational force.

[0005] The technical solution of this utility model is implemented as follows: A wall-mounted fixing structure for a hose reel includes: The hose reel body has an outwardly extending boss, and a first mounting hole is provided inside the boss. The wall mount has a second mounting hole, and the boss of the hose reel body is placed in the second mounting hole and rotatably connected to the second mounting hole. The base extends one end into the first mounting hole of the boss and rotates synchronously with the boss. A locking component is disposed inside the base and is rotatable relative to the base. One end of the locking component extends along the first mounting hole into the body of the hose reel and forms an axial limit with the support surface at the end of the first mounting hole. The other end matches the end face of the base and forms an axial limit. When the locking component rotates relative to the base, the engagement between the end of the locking component and the support surface is released, allowing the locking component to be axially extended out of the base.

[0006] Preferably, the boss is a cylindrical structure, and the second mounting hole is a circular hole that mates with the boss, used to radially limit the boss and achieve rotational engagement.

[0007] Preferably, the base includes a fixedly connected limiting plate and a step portion; the inner end wall of the limiting plate cooperates with the end face of the wall hanger for axial positioning of the base; the step portion extends into the first mounting hole of the boss and achieves synchronous rotational cooperation with the boss.

[0008] Preferably, the cross-sectional profile of the step portion and the cross-sectional profile of the first mounting hole are both corresponding irregular structures, which are used to enable the step portion and the boss to rotate synchronously through the shape matching of the irregular structures.

[0009] Preferably, the irregular structure is rectangular or elliptical.

[0010] Preferably, the second mounting hole of the wall mount is formed with a first stepped hole at its end, and the limiting plate of the base extends to the first stepped hole to keep the outer end face of the base flush with the outer surface of the wall mount.

[0011] Preferably, the locking assembly includes a locking member and a knob that are synchronously rotatably connected. The locking member has an extension section that can extend to the center hole of the base and rotate relative to the base. The end of the extension section is provided with a locking segment. When the locking segment is in the locked position, its inner side surface fits against the support surface at the end of the first mounting hole to form an axial limit. When the locking segment is rotated to the unlocked position, the inner side surface disengages from the support surface, allowing the locking segment to move axially along the first mounting hole.

[0012] Preferably, the knob includes a fixedly connected disc section and an anti-rotation shaft section. The anti-rotation shaft section extends into the shaft hole at the end of the locking member and rotates synchronously with the locking member. The disc section is located outside the center hole of the base and cooperates with the end face of the base to form an axial limit. The outer wall of the disc section has an operating lever to facilitate the rotation of the knob.

[0013] Preferably, the center hole of the base has a second stepped hole formed at one end near the outer side, and the disc section of the knob is placed at the second stepped hole so that the outer end face of the knob is flush with the outer end face of the base.

[0014] Preferably, the wall mount has several fixing holes.

[0015] By adopting the above technical solution, the beneficial effects of this utility model are as follows: This utility model provides a second mounting hole on the wall mount, allowing the boss of the hose reel body to be directly rotated and installed with high strength within the second mounting hole. Compared with the existing split-type rotating groove structure, the integrally formed mounting hole structure has higher strength and can effectively avoid problems such as cracking and disengagement caused by large rotational forces during use, thereby improving the reliability of the wall fixing structure.

[0016] This utility model adopts a corresponding irregular contour structure for the stepped part of the base and the first mounting hole in the boss, so that the two form a stable synchronous rotational fit. When the hose reel rotates, it can simultaneously drive the base and the locking component inside the base to rotate synchronously, avoiding the problem of the locking component loosening during long-term rotation, and ensuring the long-term effectiveness of the anti-loosening function.

[0017] During disassembly, this utility model allows the locking component in the locking assembly to rotate directly by rotating the external knob, causing the inner side of the locking section to disengage from the support surface at the end of the first mounting hole, thereby releasing the axial limit and allowing the locking assembly to be pulled out from the base. It has the advantages of simple structure and convenient disassembly and assembly, which helps to improve the maintenance convenience of the hose reel. Attached Figure Description

[0022] 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.

[0023] like Figure 1-6 As shown, a wall-mounted fixing structure for a hose reel includes a hose reel body 1, a wall hanger 4, a base 5, and a locking assembly.

[0024] The hose reel body 1 has an outwardly extending boss 101, with a first mounting hole 102 inside the boss 101. The wall mount 4 has a second mounting hole 401. The boss 101 of the hose reel body 1 is placed inside the second mounting hole 401 and is rotatably connected to it. In this example, the boss 101 is a cylindrical structure, and the second mounting hole 401 is a circular hole that mates with the boss 101, used for radial positioning of the boss 101 and achieving a rotational fit. Because the second mounting hole 401 in this example is directly formed on the wall mount 4, rather than being formed by splicing two semi-circular holes, the second mounting hole 401 has high structural strength when mating with the boss 101, avoiding cracking and disengagement problems in the second mounting hole 401 and the wall mount 4 itself, thus improving operational stability.

[0025] One end of the base 5 extends into the first mounting hole 102 of the boss 101 and rotates synchronously with the boss 101. Specifically, the base 5 includes a fixedly connected limiting plate 502 and a step portion 501. The cross-sectional profile of the limiting plate 502 is larger than that of the step portion 501. The inner end wall of the limiting plate 502 mates with the end face of the wall hanger 4 for axial positioning of the base 5. The step portion 501 extends into the first mounting hole 102 of the boss 101 and rotates synchronously with the boss 101. More specifically, the cross-sectional profiles of the step portion 501 and the first mounting hole 102 are corresponding irregular structures, which are used to enable the step portion 501 and the boss 101 to rotate synchronously through the shape fit of the irregular structures.

[0026] In this example, the irregular structure is rectangular, specifically a rectangle. It is understood that in other embodiments, this irregular structure can also be elliptical or other non-circular shapes, mainly used to enable the base 5 and the tube reel body 1 to rotate synchronously.

[0027] Specifically, the second mounting hole 401 of the wall mount 4 is formed with a first stepped hole 402 at its end, and the limiting plate 502 of the base 5 extends to the first stepped hole 402 to keep the outer end face of the base 5 flush with the outer surface of the wall mount 4. This mainly allows the base 5 to be completely hidden inside the wall mount 4, which is more aesthetically pleasing.

[0028] The locking component is disposed inside the base 5 and can rotate relative to the base 5. One end of the locking component extends along the first mounting hole 102 into the hose reel body 1 and forms an axial limit with the support surface 103 at the end of the first mounting hole 102. The other end matches the end face of the base 5 and forms an axial limit. When the locking component rotates relative to the base 5, the engagement between the end of the locking component and the support surface 103 is released, allowing the locking component to be axially extended out of the base 5.

[0029] Specifically, the locking assembly includes a locking member 2 and a knob 6 that are synchronously rotatably connected. The locking member 2 has an extension section 202 that extends to the center hole 504 of the base 5 and rotatably engages with the base 5. The end of the extension section 202 is provided with a locking section 201. When the locking section 201 is in the locked position, its inner surface abuts against the support surface 103 at the end of the first mounting hole 102 to form an axial limit. When the locking section 201 rotates to the unlocked position, its inner surface disengages from the support surface 103, allowing the locking section 201 to move axially along the first mounting hole 102. In this example, the cross-sectional profile of the first mounting hole 102 is designed to be rectangular. The shape of 1 is also rectangular. The length of the rectangular locking section 201 is greater than the short side of the rectangular first mounting hole 102. When the long side of the locking section 201 is perpendicular to the long side of the rectangular first mounting hole 102, the locking section 201 can be locked onto the support surface 103, thereby cooperating with the knob 6 to place the boss 101 into the second mounting hole 401 of the wall hanger 4, so that the axial direction of the boss 101 is limited. Conversely, when the long side of the locking section 201 is parallel to the long side of the rectangular first mounting hole 102, the locking section 201 is disengaged from the support surface 103, the locking component is in the unlocked state, and the hose reel body 1 can be removed from the wall hanger 4.

[0030] Specifically, the knob 6 includes a fixedly connected disc segment 602 and an anti-rotation shaft segment 601. The disc segment 602 and the anti-rotation shaft segment 601 are integrally formed. The anti-rotation shaft segment 601 extends into the shaft hole 203 at the end of the locking member 2 and rotates synchronously with the locking member 2. Specifically, the cross-sectional profile of the flip shaft segment and the shaft hole 203 are also designed as non-circular structures. In this example, a long strip structure is used to prevent relative rotation between the knob 6 and the locking member 2. After the anti-rotation shaft segment 601 is inserted into the shaft hole 203, the locking member 2 and the knob 6 are connected by screws 3 to form an integral structure.

[0031] The disc segment 602 is located outside the central hole 504 of the base 5 and mates with the end face of the base 5 to form an axial limit. The outer wall of the disc segment 602 has an operating lever 603 for driving the knob 6 to rotate. The operating lever 603 has a straight-line structure. Specifically, a second stepped hole 503 is formed at the outer end of the central hole 504 of the base 5. The disc segment 602 of the knob 6 is placed at the second stepped hole 503 so that the outer end face of the knob 6 is flush with the outer end face of the base 5.

[0032] Specifically, the wall mount 4 is provided with a number of fixing holes 403. The fixing holes 403 are mainly used to insert bolts and fix the wall mount 4 to the wall. There are four fixing holes 403.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. 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.
