Description

Technical Field

[0001] This utility model relates to the field of plastic accessories technology, and in particular to a plastic fixing bracket for a washing machine drain pipe. Background Technology

[0002] As a small accessory used to fix the drain hose, the core function of the plastic drain hose fixing bracket is to ensure the stability of the drain hose during the operation of the washing machine: it can prevent the hose from accidentally falling off or loosening, avoid slipping off the preset position due to shaking, and ensure smooth drainage; it can also block water overflow to keep the surrounding environment dry and clean, while reducing friction between the hose and other objects, reducing abnormal noise and hose wear, and extending the service life of the drain hose.

[0003] Regarding the aforementioned technologies, the inventors discovered significant technical defects in existing products. Firstly, existing plastic retainers mostly employ a one-piece injection molding process, resulting in a fixed inner cavity size for clamping the drain pipe. This makes them unsuitable for different diameter drain pipes on washing machines of varying sizes, leading to poor versatility. Secondly, to prevent odors and insects from flowing back into the washing machine through the drain pipe, users must remove the drain pipe from the drain and insert it into the retainer after each use. This significantly increases the frequency of pipe insertion and removal. Furthermore, the drain pipe undergoes considerable deformation and frequent friction during repeated installation and removal, significantly shortening its actual lifespan. Utility Model Content

[0004] The main technical problem solved by this utility model is to provide a plastic fixing bracket for a washing machine drain pipe, which enhances the versatility of the plastic fixing bracket, reduces the large deformation and friction caused by frequent installation and removal of the drain pipe, and extends the service life of the drain pipe.

[0005] To solve the above technical problems, the present invention provides a plastic fixing bracket for a washing machine drain pipe, comprising: a mounting plate and two symmetrically arranged arc-shaped frame components. The mounting plate is provided with a T-shaped groove, and a T-shaped slider is slidably connected in the T-shaped groove. The upper end of the T-shaped slider is connected to the lower end of the right arc-shaped frame component, and the left arc-shaped frame component is fixedly connected to one end of the flat surface of the mounting plate.

[0006] The mounting plate is connected to a left end plate and a right end plate at both ends. A push rod is provided on the left end plate, and an elastic telescopic rod assembly passes through the T-shaped slider and the right end plate. The push rod and the elastic telescopic rod assembly are concentrically arranged. The elastic telescopic rod assembly is fixedly connected to the T-shaped slider, and the elastic telescopic rod assembly is threadedly connected to the right end plate. The elastic telescopic rod assembly is adapted to drive the right arc-shaped frame assembly to move to the left arc-shaped frame assembly.

[0007] By adopting the above technical solution, the plastic mounting bracket must first be installed on the washing machine. Then, push the push rod to make it engage with the elastic telescopic rod assembly. Since the right-side arc-shaped frame assembly is connected to the push rod via a T-shaped slider, continuously pushing the push rod will cause the elastic telescopic rod assembly to retract, which in turn moves the right-side arc-shaped frame assembly. This operation widens the gap between the two arc-shaped frame assemblies, ensuring that the washing machine drain pipe can smoothly fit into the cavity between them without being squeezed. After placing the drain pipe, remove the external force applied to the push rod. Under the elastic force of the telescopic rod assembly, the right-side arc-shaped frame assembly will move towards the left-side arc-shaped frame assembly, thus forming a stable clamp on the drain pipe located between them. This fixing method can significantly reduce excessive deformation and friction of the drain pipe caused by frequent installation and removal, effectively extending its service life. Furthermore, the elastic telescopic rod assembly is threaded to the right end plate. When installing the mounting bracket on washing machines of different sizes, or when securing drain hoses of different diameters, the relative position of the right-side arc-shaped frame assembly can be adjusted by rotating the elastic telescopic rod assembly without extending or retracting it. This provides appropriate clamping force for drain hoses of different diameters, expanding the versatility of the mounting bracket and further improving the securing effect on the drain hose.

[0008] In a preferred embodiment, the present invention can be further configured as follows: the arc-shaped frame assembly includes an arc-shaped plate, with an inclined guide plate and a transition plate respectively connected to both ends of the arc-shaped plate, a V-shaped clamping plate provided in the inner cavity of the arc-shaped plate, and a fixing plate connected to both ends of the V-shaped clamping plate, with the outer end of the fixing plate connected to the inner surface of the arc-shaped plate.

[0009] By adopting the above technical solution, the use of inclined guide plates facilitates the guidance of drainage pipes into the inner cavity between the two arc-shaped frame components, improving the convenience of operation. The two ends of the arc-shaped plate are respectively connected to the inner surface of the arc-shaped plate through fixing plates, which facilitates the V-shaped clamping plates inside the arc-shaped frame components to firmly fix drainage pipes of different diameters, enhancing the use effect and expanding the versatility.

[0010] In a preferred embodiment, the present invention can be further configured such that: the front and rear sides of the mounting plate are respectively connected to strip plates, and the strip plates are provided with two mounting holes spaced apart.

[0011] By adopting the above technical solution, screws are inserted into the two mounting holes on the strip plate to connect with the washing machine, which improves the convenience of installation and disassembly.

[0012] In a preferred embodiment, the present invention can be further configured such that: a circular hole is provided on the left end plate, the push rod includes a push rod body passing through the circular hole, one end of the push rod body is connected to a circular plate, and the other end is spirally connected to an annular body, the outer diameter of the annular body being larger than the outer diameter of the push rod body.

[0013] By adopting the above technical solution, one end of the push rod is fixedly connected to a circular plate, and the other end is spirally connected to an annular body. This structure effectively prevents the push rod from detaching from the circular hole, achieving a reliable limiting function. During operation, the circular plate is held in hand, and the push rod is used to push the annular body to move horizontally. The annular body then compresses the elastic telescopic rod assembly, causing it to contract. Driven by the elastic telescopic rod assembly, the right-side arc-shaped frame assembly moves synchronously, thereby widening the gap between the two arc-shaped frame assemblies.

[0014] In a preferred embodiment, the present invention can be further configured as follows: the elastic telescopic rod assembly includes a cylinder sealed at one end and a spring disposed in its inner hole, the cylinder passes through and is fixedly connected to the T-shaped slider, and a driving rod is provided inside the cylinder, the driving rod spirally passing through the right end plate.

[0015] By employing the above technical solution, when an external force is applied to the push rod, the push rod drives the cylinder to displace. During this displacement, the cylinder compresses the spring, causing it to deform. Simultaneously, the cylinder, through the T-shaped slider, synchronously drives the right-side arc-shaped frame assembly to move in the same direction, gradually widening the gap between the two arc-shaped frame assemblies and providing operating space for the drain pipe to smoothly enter the inner cavity formed by the two assemblies. When the external force applied to the push rod is removed, the compressed spring releases its elastic potential energy, pushing the cylinder back to its original position under the drive of the elastic force. The cylinder then drives the right-side arc-shaped frame assembly towards the left-side arc-shaped frame assembly through the T-shaped slider, ultimately achieving stable clamping of the drain pipe in the inner cavity.

[0016] In a preferred embodiment, the present invention can be further configured as follows: the right end plate is provided with a threaded hole, the driving rod includes a screw screw that is helically connected in the threaded hole, one end of the screw screw is connected to a circular push plate body, the circular push plate body is located inside the cylinder and abuts against the end of the spring, and the other end of the screw screw is connected to a rod-shaped handle.

[0017] By adopting the above technical solution, the hand-held rod-shaped handle drives the screw to rotate, facilitating the movement of the right-side arc-shaped frame assembly and adjusting its relative position. This allows for the application of appropriate and stable clamping force to drain pipes of different diameters, enhancing the overall performance.

[0018] In a preferred embodiment, the present invention can be further configured such that: an annular limiting plate is connected to the open end of the cylinder, which is suitable for preventing the circular push plate from detaching from the inner cavity of the cylinder.

[0019] By adopting the above technical solution, the circular push plate is connected to the open end of the cylinder by an annular limiting plate, which prevents the circular push plate from detaching from the inner cavity of the cylinder, thus achieving the purpose of limiting the position.

[0020] In summary, this utility model has at least one of the following beneficial technical effects:

[0021] 1. The operating push rod, via the elastic telescopic rod assembly, drives the right-side arc-shaped frame assembly to move, widening the distance between the two arc-shaped frame assemblies. This ensures the washing machine drain hose can smoothly engage with the inner cavity between them without being squeezed. This reduces excessive deformation and friction caused by frequent assembly and disassembly, extending service life.

[0022] 2. The elasticity of the telescopic rod assembly allows the two arc-shaped frame components to form a stable clamp, ensuring reliable positioning of the drainage pipe.

[0023] 3. The elastic telescopic rod assembly is threaded to the right end plate. Rotation can adjust the position of the right arc-shaped frame, adapting to different diameter drain pipes on different washing machines and expanding the range of applications. Attached Figure Description

[0032] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0033] It should be noted that these figures are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0034] Reference Figures 1-3 The present invention discloses a plastic fixing bracket for a washing machine drain pipe, comprising: a mounting plate 1 and two symmetrically arranged arc-shaped frame components 20. The mounting plate 1 is provided with a T-shaped groove 3, and a T-shaped slider 4 is slidably connected in the T-shaped groove 3. The upper end of the T-shaped slider 4 is connected to the lower end of the right arc-shaped frame component 20, and the left arc-shaped frame component 20 is fixedly connected to one end of the upper plane of the mounting plate 1.

[0035] The mounting plate 1 is connected to a left end plate 5 and a right end plate 6 at its two ends respectively. A push rod 70 is provided on the left end plate 5. It also includes an elastic telescopic rod assembly 80 that passes through the T-shaped slider 4 and the right end plate 6. The push rod 70 and the elastic telescopic rod assembly 80 are concentrically arranged. The elastic telescopic rod assembly 80 is fixedly connected to the T-shaped slider 4. The elastic telescopic rod assembly 80 is threadedly connected to the right end plate 6. The elastic telescopic rod assembly 80 is suitable for driving the right arc-shaped frame assembly 20 to move to the left arc-shaped frame assembly 20.

[0036] The arc-shaped frame assembly 20 includes an arc-shaped plate 21. An inclined guide plate 22 and a transition plate 23 are connected to both ends of the arc-shaped plate 21, respectively. A V-shaped clamping plate 24 is provided inside the arc-shaped plate 21. A fixing plate 25 is connected to both ends of the V-shaped clamping plate 24, and the outer end of the fixing plate 25 is connected to the inner surface of the arc-shaped plate 21. The inclined guide plate 22 facilitates the guidance of the drain pipe into the cavity between the two arc-shaped frame assemblies 20, improving operational convenience. The fixing plates 25 connect both ends of the arc-shaped plate 21 to its inner surface, allowing the V-shaped clamping plate 24 inside the arc-shaped frame assembly 20 to securely fix drain pipes of different diameters, enhancing usability and expanding versatility.

[0037] The front and rear sides of the mounting plate 1 are respectively connected to strip plates 9, and two mounting holes 11 are provided on the strip plates 9 at intervals. Screws are inserted into the two mounting holes 11 on the strip plates 9 to connect with the washing machine, which improves the convenience of installation and disassembly.

[0038] The left end plate 5 has a circular hole 12. The push rod component 70 includes a push rod body 71 passing through the circular hole 12. One end of the push rod body 71 is connected to a circular plate 72, and the other end is spirally connected to an annular body 73. The outer diameter of the annular body 73 is larger than the outer diameter of the push rod body 71. One end of the push rod body 71 is fixedly connected to the circular plate 72, and the other end is spirally connected to the annular body 73. This structure can effectively prevent the push rod body 71 from disengaging from the circular hole 12, achieving a reliable limiting function. During operation, the circular plate 72 is held, and the annular body 73 is pushed to translate by the push rod body 71. The annular body 73 then squeezes the elastic telescopic rod assembly 80 to retract. Driven by the elastic telescopic rod assembly 80, the right arc-shaped frame assembly 20 moves synchronously, thereby widening the gap between the two arc-shaped frame assemblies 20.

[0039] The elastic telescopic rod assembly 80 includes a cylinder 81 sealed at one end and a spring 82 disposed in its inner hole. The cylinder 81 passes through and is fixedly connected to the T-shaped slider 4. A driving rod 83 is provided inside the cylinder 81, and the driving rod 83 spirally passes through the right end plate 6. When an external force is applied to the push rod 70, the push rod drives the cylinder 81 to move. During the displacement, the cylinder compresses the spring 82, causing it to deform. At the same time, the cylinder synchronously drives the right arc-shaped frame assembly 20 to move in the same direction through the T-shaped slider 4, thereby gradually widening the gap between the two arc-shaped frame assemblies and providing operating space for the drain pipe to smoothly enter the inner cavity formed by the two. When the external force applied to the push rod 70 is removed, the spring 82, which is in a compressed state, releases its elastic potential energy and pushes the cylinder 81 to return to its original position under the drive of the elastic force. The cylinder then drives the right arc-shaped frame assembly 20 to move towards the left arc-shaped frame assembly 20 through the T-shaped slider 4, ultimately achieving stable clamping of the drain pipe in the inner cavity.

[0040] The right end plate 6 has a threaded hole 13. The driving rod 83 includes a screw 831 screwed into the threaded hole 13. One end of the screw 831 is connected to a circular push plate 832, which is located inside the cylinder 81 and abuts against the end of the spring 82. The other end of the screw 831 is connected to a rod-shaped handle 833. Holding the rod-shaped handle 833 drives the screw 831 to rotate, facilitating the movement of the right-side arc-shaped frame assembly 20 and adjusting its relative position. This allows for the application of a suitable and stable clamping force to drain pipes of different diameters, enhancing the usability.

[0041] An annular limiting plate 14 is connected to the open end of the cylinder 81, which is suitable for preventing the circular push plate 832 from disengaging from the inner cavity of the cylinder 81. The annular limiting plate 14 connected to the open end of the cylinder 81 prevents the circular push plate 832 from disengaging from the inner cavity of the cylinder 81, thus serving a limiting purpose.

[0042] The implementation principle of this embodiment is as follows: When using this plastic fixing bracket, it must first be installed on the washing machine. Then, push the push rod 70 to make it contact and connect with the elastic telescopic rod assembly 80. Since the right arc-shaped frame assembly 20 is connected to the push rod 70 through the T-shaped slider 4, continuously pushing the push rod 70 can drive the elastic telescopic rod assembly 80 to retract, thereby causing the right arc-shaped frame assembly 20 to move. This operation widens the distance between the two arc-shaped frame assemblies 20, ensuring that the washing machine drain pipe can smoothly fit into the cavity between them without being squeezed. After the drain pipe is placed, the external force applied to the push rod 70 is removed. Under the elastic force of the elastic telescopic rod assembly 80, the right arc-shaped frame assembly 20 will move closer to the left arc-shaped frame assembly 20, thus forming a stable clamp on the drain pipe located between them. This fixing method can significantly reduce excessive deformation and friction of the drain pipe caused by frequent installation and removal, effectively extending its service life. Furthermore, the elastic telescopic rod assembly 80 and the right end plate 6 are connected by threads. When installing the mounting bracket on washing machines of different sizes, or when fixing drain hoses of different diameters, the relative position of the right-side arc-shaped frame assembly 20 can be adjusted by rotating the elastic telescopic rod assembly 80 without extending or retracting it. This provides a suitable clamping force for drain hoses of different diameters, expanding the versatility of the mounting bracket and further improving the fixing effect on the drain hose.
