Description

Technical Field

[0001] This utility model relates to the field of fluid transmission device technology, specifically a flexible hose for connecting an angle valve and a spray gun, which is particularly suitable for flexible connection between the angle valve and the spray gun and spray gun support in scenarios such as bathroom equipment and cleaning devices. Background Technology

[0002] In bathroom and cleaning appliance applications, flexible hoses are commonly used as connectors between fittings, linking angle valves and spray guns. Traditionally, the connecting nuts at both ends of the hose are only used for threaded connections to the angle valve and spray gun interfaces, offering limited functionality. In practice, when not in use, the spray gun lacks a reliable temporary placement location, often requiring additional hooks or brackets, resulting in cluttered spaces and inconvenient operation. Furthermore, existing brackets are mostly fixed to walls or equipment and cannot move with the hose, limiting their applicability.

[0003] Some existing technologies attempt to place a bracket between the hose and the angle valve, but the following problems exist:

[0004] 1. Existing brackets need to be purchased separately, which not only increases costs, but also makes the installation of additional brackets more troublesome, and users usually cannot replace them themselves;

[0005] 2. The connection structure is not stable enough, and the bracket is prone to shaking or falling off, which affects the safety of the spray gun placement;

[0006] Therefore, there is an urgent need for a flexible hose that can be directly integrated into a spray gun holder to achieve stable support and flexible adaptation of the spray gun. Utility Model Content

[0007] The purpose of this invention is to provide a flexible hose with a bracket for use between an angle valve and a spray gun. By integrating a bracket on the connecting nut, the spray gun can be supported nearby, solving the problems of inconvenient spray gun placement and difficult bracket adjustment in the prior art.

[0008] The purpose of this utility model is achieved as follows: a hose with a spray gun bracket includes a hose body, with connecting nuts provided at both ends of the hose body, at least one of the connecting nuts being a bracket nut, the bracket nut being sleeved on the outside of the hose body, and a bracket being sleeved on the outer peripheral wall of the bracket nut; the bracket and the bracket nut are detachably connected.

[0009] In the aforementioned hose with a spray gun bracket, the bracket includes a fixed end and a free end arranged opposite to each other. The outer peripheral wall of the bracket nut is provided with an annular fixing surface. The inner wall of the fixed end and the outer peripheral wall of the annular fixing surface form a rotatable sleeve fit, and are relatively fixed to the bracket nut in the circumferential and axial directions by a fixing component.

[0010] In the aforementioned hose with a spray gun bracket, the fixing assembly includes a limiting step and a limiting member disposed on the outer peripheral wall of the bracket nut. When the fixing end is axially slidably sleeved along the annular fixing surface, the fixing end is fixed to the bracket nut by the limiting step and the limiting member.

[0011] In the aforementioned hose with a spray gun bracket, the limiting element is a snap ring or a nut. When the limiting element is a snap ring, a first annular groove is formed on the outer peripheral wall of the bracket nut. When the fixed end moves towards the limiting step and abuts against the limiting step, the snap ring engages with the first annular groove to restrict the axial movement of the fixed end. When the limiting element is a nut, an external threaded connection is formed on the outer peripheral wall of the bracket nut. When the fixed end moves towards the limiting step and abuts against the limiting step, the nut engages with the external threaded connection to restrict the axial movement of the fixed end.

[0012] In the aforementioned hose with a spray gun bracket, a damping assembly is provided between the bracket and the bracket nut. The damping assembly includes a second annular groove formed on the outer peripheral wall of the annular fixed surface, and an elastic damping element embedded in the second annular groove. The outer peripheral surface of the elastic damping element is in interference contact with the inner wall of the fixed end to provide circumferential rotational damping force.

[0013] In the aforementioned hose with spray gun bracket, the elastic damping element is an O-ring, and the cross-sectional diameter of the O-ring is greater than the groove depth of the second annular groove, so as to form a radial interference fit when the fixed end is sleeved on the annular fixed surface.

[0014] In the aforementioned hose with a spray gun bracket, the bracket includes a support arm connecting the fixed end and the free end, the support arm extending radially or obliquely along the bracket nut.

[0015] In the aforementioned hose with a spray gun bracket, the free end is provided with a spray gun bearing structure, which is a clamping arm for holding the spray gun.

[0016] The outstanding and beneficial technical effects of this utility model compared to the prior art are:

[0017] 1. Precise scene adaptation: Specifically designed for the connection scene between the angle valve and the spray gun, the bracket is directly integrated into the hose connection nut, realizing the nearby support of the spray gun without the need for additional bracket installation;

[0018] 2. Adjustable and stable angle: The detachable connection with damping components supports 360° circumferential adjustment and locking of the bracket, adapting to different installation angles such as vertical installation of wall angle valves and horizontal installation of countertop angle valves;

[0019] 3. Reliable connection: The combination design of the limiting component (circlip or nut) and O-ring ensures axial fixation and circumferential damping, prevents the bracket from loosening, and ensures the safe placement of the spray gun. Attached Figure Description

[0034] The present invention will be further described below with reference to specific embodiments:

[0035] like Figures 1-7As shown, this utility model relates to a hose with a spray gun bracket, including a hose body 100. Connecting nuts 200 are respectively provided at both ends of the hose body 100, at least one of which is a bracket nut 200a. Specifically, when the hose body is used to connect an angle valve 600 and a spray gun 300, the connecting nut 200 at one end of the hose body 100 is a common nut connected to the spray gun, and the other end is a bracket nut 200a connected to the angle valve 600. The bracket nut 200a is sleeved on the outside of the hose body 100, and a bracket 230 is sleeved on the outer peripheral wall of the bracket nut 200a. The bracket 230 and the bracket nut 200a are detachably connected. This design allows the bracket 230 to be easily installed and disassembled, facilitating maintenance and replacement, while improving the overall flexibility and applicability of the hose. During operation, the bracket nut 200a securely fixes the bracket 230 to the hose body 100, ensuring that the bracket 230 will not loosen or fall off during use, thereby providing stable support for the spray gun 300.

[0036] Preferably, the bracket 230 includes a fixed end 231 and a free end 232 disposed opposite to each other. An annular fixing surface 201 is provided on the outer peripheral wall of the bracket nut 200a. The inner wall of the fixed end 231 and the outer peripheral wall of the annular fixing surface 201 form a rotatable sleeve fit, and are relatively fixed circumferentially and axially to the bracket nut 200a by the fixing component 400. This structural design allows the bracket 230 to rotate flexibly within a certain range, while the fixing component 400 ensures its stability during use, preventing the bracket 230 from loosening or shifting due to external forces. During operation, the user can manually rotate the bracket 230 to adjust the angle and position of the spray gun 300 according to actual needs, and then fix the bracket 230 in the required position by the fixing component 400. This allows the bracket 230 to be adjusted in angle during installation to adapt to the placement requirements of the spray gun, thereby achieving precise positioning of the spray gun 300.

[0037] Preferably, the fixing assembly 400 includes a limiting step 210 and limiting members 402 / 404 disposed on the outer peripheral wall of the bracket nut 200a. When the fixing end 231 is axially slidably sleeved along the annular fixing surface 201, the fixing end 231 is fixed to the bracket nut 200a by the limiting step 210 and the limiting members 402 / 404. Specifically, when the limiting member is a retaining spring 402, a first annular groove 401 is formed on the outer peripheral wall of the bracket nut 200a. When the fixing end 231 moves towards the limiting step 210 and abuts against the limiting step 210, the retaining spring 402 engages with the first annular groove 401 to limit the axial movement of the fixing end 231. This retaining spring 402 limiting method has a simple structure, is easy to install, and can quickly fix the bracket 230, improving work efficiency. When the limiting component is nut 404, an external threaded connection is formed on the outer peripheral wall of the bracket nut 200a. When the fixed end 231 moves towards the limiting step 210 and abuts against the limiting step 210, the nut 404 engages with the external threaded connection to restrict the axial movement of the fixed end 231. The nut 404 limiting method provides higher fixing strength and stability, suitable for scenarios where the stability of the bracket 230 is required. During operation, users can select different limiting components (circlip 402 or nut 404) to meet different usage needs, ensuring that the bracket 230 does not move axially during use, thereby guaranteeing the stability of the spray gun 300.

[0038] Preferably, a damping assembly 500 is provided between the bracket 230 and the bracket nut 200a. The damping assembly 500 includes a second annular groove 403 formed on the outer peripheral wall of the annular fixed surface 201, and an elastic damping element 501 embedded in the second annular groove 403. The outer peripheral surface of the elastic damping element 501 is in interference fit with the inner wall of the fixed end 231 to provide circumferential rotational damping force. Specifically, the elastic damping element 501 is an O-ring, and the cross-sectional diameter of the O-ring is larger than the groove depth of the second annular groove 403 to form a radial interference fit when the fixed end 231 is sleeved on the annular fixed surface 201. This design of the damping assembly 500 enables the bracket 230 to generate appropriate damping force when rotating, thereby achieving smooth and vibration-free rotation and improving the stability and operational accuracy of the spray gun 300 during use. During operation, when the user rotates the bracket 230, the elastic damping element 501 provides a uniform circumferential rotational damping force, allowing the bracket 230 to rotate smoothly to any desired position without causing unnecessary shaking or swaying due to external forces, thereby ensuring the stability of the spray direction of the spray gun 300.

[0039] Preferably, the bracket 230 includes a support arm 233 connecting the fixed end 231 and the free end 232, the support arm 233 extending radially or obliquely along the bracket nut 200a. This design allows for flexible adjustment of the extension direction of the support arm 233 according to actual usage needs, thereby optimizing the support position and angle of the spray gun 300 and further improving the ease of use and stability of the spray gun 300. During operation, the user can select the appropriate extension direction of the support arm 233 according to the usage scenario and operational requirements of the spray gun 300, ensuring the spray gun 300 is in the optimal position, improving work efficiency and operational convenience.

[0040] Preferably, the free end 232 is equipped with a spray gun support structure, which is a clamping arm for holding the spray gun 300. This clamping arm design ensures that the spray gun 300 is securely fixed to the bracket 230, preventing it from shaking or falling off due to external force or improper operation during use. This ensures stable spray direction of the spray gun 300, improving work efficiency and quality. During operation, the user places the spray gun 300 in the clamping arm, and the clamping force of the arm securely fixes the spray gun 300 to the bracket 230, ensuring that the spray gun 300 will not shake or fall off due to external force during use, thus guaranteeing stable spray direction and improving work efficiency and quality.

[0041] Through the above design, the hose with spray gun bracket of this utility model can not only stably support the spray gun 300, but also flexibly adjust the position and angle of the spray gun 300 according to actual needs, thereby improving the stability and ease of operation of the spray gun 300.

[0042] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape, and principle of the present utility model should be covered within the scope of protection of the present utility model.
