Description

Technical Field

[0001] This utility model relates to the field of glass cover plates, specifically to a quick-installing snap-on glass cover plate assembly for washing machines. Background Technology

[0002] As a key component for interaction between the washing machine and the user, the glass observation window cover assembly must not only meet the basic needs of users to observe the washing status of clothes in the drum in real time and to conveniently put in and take out clothes, but its installation and fixing method must also take into account the overall sealing of the washing machine to prevent water leakage during the washing process. At the same time, it must be adapted to the vibration environment of the washing machine during operation to ensure structural stability during long-term use. Therefore, the rationality of its installation and fixing structure is crucial to the user experience and product performance of the washing machine.

[0003] The glass viewing window cover of existing drum washing machines generally uses a fixing scheme with a pressure ring and multiple fastening components. Typically, a metal or plastic pressure ring is used as an auxiliary fixing component, along with multiple screws to connect the cover to the cabinet. During installation, the glass cover and pressure ring must first be precisely aligned with the preset holes in the cabinet opening. Then, a special tool is used to screw each screw into the corresponding hole, and the tightness is repeatedly adjusted. If there is a slight misalignment of the screw holes, disassembly and adjustment are required again. The operation process is complex and requires high assembly precision. If subsequent repairs or replacements are needed due to cover damage or aging of the sealing ring, all screws must be unscrewed one by one using tools. If the screws become rusted or stripped after long-term use, or if the tools and screws are incompatible, disassembly becomes even more difficult, not only prolonging repair time but also placing an additional operational burden on after-sales personnel and users. Utility Model Content

[0004] The purpose of this utility model is to solve the above defects and provide a quick-installing snap-on washing machine glass cover assembly. By moving the unlocking lever, the elastic metal claws can be separated from the L-shaped slot, making it easy to quickly remove the glass cover and solving the technical problem of further increasing the difficulty of disassembly in the prior art.

[0005] The objective of this utility model is achieved through the following means:

[0006] A quick-installing snap-on washing machine glass cover assembly includes a fixing base, a glass cover plate at the center of the fixing base, a sealing ring between the fixing base and the glass cover plate, the fixing base having an overall annular design, the glass cover plate having an overall circular design, bolts evenly distributed on the surface of the fixing base, L-shaped slots evenly distributed on the inner circumferential surface of the fixing base, a metal edging plate with an overall annular design on the edge of the glass cover plate, elastic metal claws evenly distributed on the outer circumferential surface of the metal edging plate, the elastic metal claws corresponding to the L-shaped slots, a locking protrusion at the center of the outer end of the elastic metal claw, a guide slope on the lower surface of the outer end of the elastic metal claw, and an unlocking lever at the center of the elastic metal claw.

[0007] Align the glass cover with the fixing seat and press it down. The guide slope is pressed and the elastic metal claws retract inward. After the locking protrusion passes the edge of the fixing seat, the elastic metal claws spring back and drive the locking protrusion into the L-shaped slot to complete the locking.

[0008] By using a tool or your finger to move the unlock lever, the lever causes the elastic metal claw to retract, disengaging the locking protrusion from the L-shaped slot, allowing you to remove the glass cover.

[0009] Furthermore, a sealing ring groove is provided on the lower part of the inner circumferential surface of the fixing seat, and the sealing ring is installed in the inner cavity of the sealing ring groove.

[0010] By fitting the sealing ring and the sealing ring groove together, the device effectively prevents external dust or moisture and other impurities from entering the device, while also preventing the leakage of internal media, thus providing basic sealing protection and improving the reliability of the device.

[0011] Furthermore, the cross-section of the sealing ring groove is a trapezoidal design that is narrower at the top and wider at the bottom, and positioning protrusions are added to the top and bottom of the sealing ring.

[0012] The trapezoidal sealing ring groove, which is narrower at the top and wider at the bottom, structurally restricts the axial movement of the sealing ring, preventing it from falling off during use; the positioning protrusion further enhances the installation stability of the sealing ring in the groove, reduces the risk of displacement, and ensures the continuous and stable sealing effect.

[0013] Furthermore, the upper and lower parts of the inner cavity of the sealing ring groove are provided with positioning grooves, and the positioning protrusion is engaged with the corresponding positioning groove.

[0014] The locking connection between the positioning protrusion and the positioning groove achieves circumferential fixation of the sealing ring, preventing circumferential displacement of the sealing ring due to vibration during device operation, further enhancing the stability of the sealing structure, and ensuring that the sealing performance is not affected by displacement.

[0015] Furthermore, the outer peripheral surface of the metal edging is uniformly provided with external through holes, and disc-shaped spring washers are installed in the inner cavity of each external through hole. The outer end of the disc-shaped spring washer is in contact with the corresponding elastic metal claw.

[0016] Disc-shaped spring washers supplement the elasticity of the elastic metal claws, alleviate metal fatigue after long-term use, and prevent the lock from loosening; at the same time, they buffer the impact force when the elastic metal claws move, reduce structural damage, and improve the service life and locking stability of the elastic metal claws.

[0017] Furthermore, reinforcing ribs are evenly installed on the upper and lower parts of the inner cavity of the fixing seat.

[0018] The reinforcing ribs enhance the radial rigidity and structural strength of the fixing base, preventing deformation caused by uneven screw force during pre-fixation, and also preventing structural aging and deformation after long-term use, thus ensuring the structural stability of the fixing base and the entire device.

[0019] The beneficial effects of this utility model are as follows: the elastic metal claws uniformly installed on the outer circumferential surface of the metal edging of the glass cover plate have a guide slope on the lower surface of their outer end, and the elastic metal claws correspond to the L-shaped slots uniformly opened on the inner circumferential surface of the fixing base. The locking protrusion at the center of the outer end of the elastic metal claw can be inserted into the L-shaped slot, making the installation process of the glass cover plate and the fixing base simple, fast and convenient, without the need for complicated fastening operations.

[0020] An unlocking lever is added to the center of the flexible metal claw. When it is necessary to remove the glass cover, the flexible metal claw can be separated from the L-shaped slot by moving the unlocking lever, which makes it easy to quickly remove the glass cover and improves the convenience of maintenance or replacement.

[0028] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0029] In this embodiment, refer to Figures 1-6 The specific implementation of a quick-installation snap-on washing machine glass cover assembly includes a fixing base 3, a glass cover 1 at the center of the fixing base 3, a sealing ring 9 between the fixing base 3 and the glass cover 1, the fixing base 3 having an overall annular design, the glass cover 1 having an overall circular design, bolts evenly distributed on the surface of the fixing base 3, L-shaped slots 7 evenly distributed on the inner circumferential surface of the fixing base 3, a metal edging 2 installed on the edge of the glass cover 1, the metal edging 2 having an overall annular design, elastic metal claws 4 evenly distributed on the outer circumferential surface of the metal edging 2, the elastic metal claws 4 corresponding to the L-shaped slots 7, a locking protrusion 5 at the center of the outer end of the elastic metal claw 4, a guide slope at the lower surface of the outer end of the elastic metal claw 4, and an unlocking lever 6 at the center of the elastic metal claw 4.

[0030] By using the flexible metal claw 4 and the L-shaped slot 7, the traditional multi-screw installation method is replaced, enabling quick installation and disassembly, which greatly improves production efficiency and maintenance convenience.

[0031] The elastic metal claws 4 are evenly distributed around the periphery to ensure balanced force distribution. The L-shaped groove 7 and the locking protrusion 5 form an anti-detachment fit to ensure that the glass cover 1 will not loosen when the washing machine vibrates during high-speed spin-drying.

[0032] The mechanical snap-fit ​​structure simplifies the complex installation process, highlighting the core characteristics of utility model patents: small innovations with great benefits.

[0033] like Figure 2 and Figure 3 As shown, a sealing ring groove 8 is provided on the lower part of the inner circumferential surface of the fixed base 3, and the sealing ring 9 is installed in the inner cavity of the sealing ring groove 8.

[0034] The sealing ring groove 8 provides installation and bearing space for the sealing ring 9, and the sealing ring 9 forms a sealing fit with the sealing surface of the device through its own structure.

[0035] The sealing ring groove 8 has a trapezoidal cross-section that is narrower at the top and wider at the bottom, and the top and bottom of the sealing ring 9 are provided with positioning protrusions 13.

[0036] The trapezoidal sealing ring groove 8 provides axial positioning for the sealing ring 9, and the positioning protrusion 13 fits and limits the sealing ring 9 when it is embedded in the sealing ring groove 8.

[0037] The upper and lower parts of the inner cavity of the sealing ring groove 8 are provided with positioning grooves, and the positioning protrusion 13 is engaged with the corresponding positioning groove.

[0038] The positioning protrusion 13 of the sealing ring 9 is fixed to the positioning groove of the sealing ring groove 8 by a snap-fit ​​action, and the circumferential rotation of the sealing ring 9 is restricted by the snap-fit ​​structure.

[0039] like Figure 4 , Figure 5 and Figure 6 As shown, the outer circumferential surface of the metal edging 2 is uniformly provided with external through holes 11, and the inner cavity of each external through hole 11 is equipped with a disc spring washer 12. The outer end of the disc spring washer 12 is in contact with the corresponding elastic metal claw 4.

[0040] When the elastic metal claw 4 moves, it causes the disc spring washer 12 to undergo elastic deformation. The disc spring washer 12 then resets itself through its own elasticity, causing the elastic metal claw 4 to return to its initial position.

[0041] Reinforcing ribs 10 are evenly installed on the upper and lower parts of the inner cavity of the fixing seat 3.

[0042] The reinforcing rib 10 disperses the external force borne by the fixing seat 3 through its own structure, and evenly transmits the force to the entire fixing seat 3.

[0043] The usage process of a quick-installing snap-on washing machine glass cover assembly in this embodiment is as follows: the sealing ring 9 is embedded into the sealing ring groove 8 of the fixing seat 3, and the positioning protrusion 13 forms a snap-fit ​​connection with the sealing ring 9 and the positioning groove of the sealing ring groove 8.

[0044] A disc spring washer 12 is installed in the inner cavity of the outer through hole 11 of the metal edging 2, so that the outer end of the disc spring washer 12 fits against the corresponding elastic metal claw 4.

[0045] Press the glass cover plate 1 against the fixing seat 3. The guide slope is pressed and the elastic metal claw 4 retracts inward. After the locking protrusion 5 passes the edge of the fixing seat 3, the elastic metal claw 4 springs back and the locking protrusion 5 is inserted into the L-shaped groove 7.

[0046] Reinforcing ribs 10 are installed on the upper and lower parts of the inner cavity of the fixing seat 3. The reinforcing ribs 10 disperse the external force borne by the fixing seat 3 and evenly transmit it to the entire fixing seat 3.

[0047] By using a tool or finger to move the unlock lever 6, the unlock lever 6 causes the elastic metal claw 4 to retract inward, the locking protrusion 5 to disengage from the L-shaped slot 7, and the glass cover plate 1 can be removed.

[0048] When the elastic metal claw 4 moves, it causes the disc spring washer 12 to undergo elastic deformation. The disc spring washer 12 then resets itself through its own elasticity, causing the elastic metal claw 4 to return to its initial position.

[0049] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the scope of protection of the present invention.
