[0001] This disclosure relates to the field of clothing processing apparatus technology, and more particularly to a clothing processing apparatus. Background Technology

[0002] In a clothing handling device capable of opening and closing, if the mechanism controlling the opening and closing of the clothing handling device fails, that is, if the system mistakenly believes that the clothing handling device in the closed state has switched to the open state, and at this time the clothing handling device is still undergoing violent movement, there is a high risk of explosion, endangering the user's property and life safety.

Detailed Implementation

[0029] To better understand the above-mentioned objectives, features, and advantages of this disclosure, the solutions disclosed herein will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0030] Numerous specific details are set forth in the following description in order to provide a full understanding of this disclosure, but this disclosure may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some, and not all, of the embodiments of this disclosure.

[0031] In a clothing handling device capable of opening and closing, if the mechanism controlling the opening and closing of the clothing handling device fails, that is, if the system mistakenly believes that the clothing handling device in the closed state has switched to the open state, and at this time the clothing handling device is still undergoing violent movement, there is a high risk of explosion, endangering the user's property and life safety.

[0032] Based on this, this embodiment provides a clothing processing device. A sealing ring is positioned at the drain hole and used to seal it, thereby ensuring the sealing of the inner cylinder of the clothing processing device. When the pressure inside the inner cylinder reaches a set value, the portion where the pressure plate and the sealing ring elastically abut against each other begins to deform, creating a gap. At this time, some liquid flows through the gap and out from the first pressure relief port, thus achieving pressure relief. This ensures both good sealing performance of the clothing processing device and stability of the internal environment of the inner cylinder, allowing for timely pressure relief in case of high pressure, significantly improving the practicality and safety of the clothing processing device. A detailed description follows with specific embodiments:

[0033] Reference Figures 1 to 9This embodiment provides a garment processing device, including an inner tube with a drain hole and a drain valve at the drain hole. The drain valve includes a slidingly engaged movable part 1 and a fixed part 2. The movable part 1 is used to open and close the drain hole. The movable part 1 includes a counterweight 6 and an injection molded part. The injection molded part includes a first injection molded part 11 and a second injection molded part 12. The first injection molded part 11 includes a first injection molded part body covering the counterweight 6. The first injection molded part body has a first clearance portion 111, which is used to expose part of the counterweight 6 to form a first gripping station. The second injection molded part 12 includes a second injection molded part body covering the counterweight 6 and located at a position corresponding to at least part of the first clearance portion 111. The second injection molded part body has a second clearance portion 121, which is used to expose part of the first injection molded part 11 to form a second gripping station.

[0034] The injection molded part formed by two injection molding steps allows the part that needs to be connected and fixed by the first gripping station during the first injection (i.e., the first clearance part 111) to be filled in the second injection. This allows the first injection molded part 11 and the second injection molded part 12 to cooperate to form an integral injection molded part that can completely wrap the counterweight 6, thereby achieving the purpose of completely isolating the counterweight 6 from the external environment, thus better protecting the counterweight 6, extending the service life of the counterweight 6, and reducing the probability of the counterweight 6 being corroded.

[0035] In some embodiments, the number of first clearance portions 111 is three, and the three first clearance portions 111 are evenly arranged circumferentially on the periphery of the counterweight 6; this arrangement can better fix the counterweight 6 and ensure its position during the injection molding process.

[0036] In a further embodiment, the counterweight 6 is a cylindrical structure, and the first injection molded part 11 also includes a positioning structure 13 and a connecting structure 14. The positioning structure 13, the body of the first injection molded part and the counterweight 6 are coaxially arranged, and a connecting structure 14 is formed between two adjacent first clearance parts 111. That is, the first injection molded part 11 forms a connecting structure 14 at the gap between the three claws of the fixing device, and the positioning structure 13 is connected to the body of the first injection molded part through the connecting structure 14.

[0037] It should be understood that the first injection molded part body has two sets of first clearance parts 111 on both sides along its axial direction, and each set of first clearance parts 111 has three parts. There are two positioning structures 13, which are respectively set at both ends of the counterweight block 6. Both positioning structures 13 are connected to the first injection molded part body through the connecting structure 14.

[0038] When the counterweight 6 is a cylindrical structure, the positioning structure 13, the first injection molded part 11, and the counterweight 6 are coaxially arranged. In some embodiments, the second injection molded part 12 also includes a positioning groove, which is arranged opposite to the positioning structure 13 and matches the shape of the positioning structure 13. This arrangement ensures that the positioning grooves on the positioning structure 13 and the second injection molded part 12 that match the positioning structure 13 are all located on the axis of the counterweight 6, which can ensure that the strength at the connection between the first injection molded part 11 and the second injection molded part 12 is relatively uniform, and the overall structure formed after connection is more stable and firm.

[0039] Reference Figure 3 , Figure 4 and Figure 9 As shown, the molding method for an injection molded part provided in this embodiment includes the following steps:

[0040] S1. The counterweight 6 is fixed inside the mold by using a fixing device to connect multiple first gripping stations on the counterweight 6;

[0041] S2. Inject the first injection molded part 11, and the position of the first injection molded part 11 opposite to the first gripping station forms a first clearance part 111;

[0042] S3. Using a fixing device, the first injection molded part 11 and the counterweight 6 enclosed by it are fixed in the mold by connecting multiple second gripping stations on the first injection molded part 11.

[0043] S4. Inject the second injection molded part 12. The second injection molded part 12 is formed at the position of the first clearance part 111 and is connected with the first injection molded part 11 to form an integral structure.

[0044] In this process, the two-step injection molding in S2 and S4 allows the portion initially blocked by the fixing device (i.e., the first clearance part 111) to be filled in the second injection molding, forming a one-piece injection molded part that completely encloses the counterweight 6. This achieves complete isolation of the counterweight 6 from the external environment, thereby better protecting the counterweight 6, extending its service life, and reducing the probability of corrosion. It should be noted that S3 and S4 can be repeated multiple times, forming multiple injection molded parts to completely enclose the counterweight 6. The packaging can be completed as long as each injection fills a portion of the exposed part of the counterweight 6 remaining from the previous injection. That is, if the second injection part 12 does not completely fill the first clearance part 111 (that is, if there is a gap between the first injection part 11 and the second clearance part 121 and / or between the second injection part 12 and the first clearance part 111), the unfilled gaps can be filled in the next injection until the exposed part of the counterweight 6 is completely filled. The specific situation needs to be preliminarily calculated based on the shape and volume of the counterweight 6.

[0045] In some embodiments, the fixing device is a three-jaw clamp. In S1 and S3, the three jaws of the fixing device clamp the three first gripping positions and the three second gripping positions along the circumference, respectively. The three jaws of the fixing device can be a structure that moves synchronously in the radial direction or a structure that can be adjusted independently in the radial direction. The choice can be made according to the shape of the counterweight 6. When the counterweight 6 is a cylindrical structure, a fixing device with three jaws that move synchronously in the radial direction can be selected to fix the counterweight 6. At this time, the three-jaw structure and the counterweight 6 are in a coaxial position, making the operation simpler, the fixing and disassembly more efficient, and the fixing effect better.

[0046] In some embodiments, in S2, the first injection molded part 11 includes a positioning structure 13, a connecting structure 14, and a first injection molded part body. The first injection molded part body wraps around the counterweight 6 in the circumferential direction. The positioning structure 13 is formed at the end of the first injection molded part 11 along its axial direction. The connecting structure 14 is formed at the gap between the three claws of the fixing device. The positioning structure 13 is connected to the first injection molded part body through the connecting structure 14. The positioning structure 13 can provide more fixing points during the injection process of the second injection molded part 12, and can also facilitate the accurate positioning of the second injection molded part 12 and the first injection molded part 11.

[0047] In a further embodiment, the first injection molded part body is provided with two sets of first clearance parts 111 on both sides along its axial direction, with three first clearance parts 111 in each set. There are two positioning structures 13, which are respectively arranged at both ends of the counterweight block 6. Both positioning structures 13 are connected to the first injection molded part body through the connecting structure 14. This enables more accurate coaxial positioning of the first injection molded part 11 and the second injection molded part 12, resulting in better injection molding effect. It also provides more stable support when injection molding the second injection molded part 12.

[0048] In some embodiments, there is a set distance between the first gripping station and the second gripping station. It should be understood that when the second injection molded part 12 is injection molded, the contact point between the second injection molded part 12 and the first injection molded part 11 may be affected by high-temperature liquid plastic, causing part of the first injection molded part 11 to melt (the second injection molded part 12 and the first injection molded part 11 are combined into an integral structure in this way). When there is a set distance between the first gripping station and the second gripping station, it can be ensured that the first gripping station is at a certain distance from the melted part. This not only ensures the reliability of the clamping and fixing of the first injection molded part 11, but also prevents the first injection molded part 11 from being clamped and deformed and forming unnecessary injection molding structures. In other words, the connection between the second injection molded part 12 and the first injection molded part 11 will not have too much impact on the molding of the second injection molded part 12 and the first injection molded part 11.

[0049] In a further embodiment, the fixing device is provided with a hook groove, which is used to form a hook-shaped structure on the first injection molded part 11. It should be understood that the hook groove can be curved, sawtooth, or other shapes, as long as it can form a hook-shaped structure when the first injection molded part 11 is injection molded, and the hook-shaped structure can form a matching structure on the second injection molded part 12. In this way, the connection can be achieved without completely fusing the first injection molded part 11 and the second injection molded part 12, and the hook-shaped structure can be used to strengthen the connection strength between the two.

[0050] Continue to refer to Figures 1 to 8 As shown, the drain valve also includes an elastic element 3 and a limiting element; the fixed element 2 is connected to the inner cylinder; the movable element 1 is slidably connected to the fixed element 2; the movable element 1 has a receiving groove 15, which extends along the sliding direction of the movable element 1, and the elastic element 3 is disposed in the receiving groove 15; the first end and the second end of the elastic element 3 are respectively abutted against the movable element 1 and the fixed element 2, and the elastic element 3 is used to close the drain hole of the movable element 1; the limiting element is disposed on the movable element 1 and / or the fixed element 2, and the limiting element is limited to the first end and / or the second end of the elastic element 3 to restrict the elastic element 3 from coming out of the receiving groove 15; it should be understood that the extension and retraction direction of the elastic element 3 can be the same as the sliding direction of the movable element 1, or it can be at a certain angle to the sliding direction of the movable element 1, as long as the elasticity of the elastic element 3 can be used to reset the movable element 1.

[0051] In assembling the garment processing device, one end of the elastic element 3 is first connected to the limiting member on the movable element 1 and / or the fixed element 2. Then, the elastic element 3 is compressed and inserted into the receiving groove 15 along the direction of the receiving groove 15. At the same time, the movable element 1 is completely installed into the fixed element 2, so that the outer wall of the movable element 1 fits against the inner wall of the fixed element 2, ensuring the sliding fit between the movable element 1 and the fixed element 2. Alternatively, the movable element 1 can be installed on the fixed element 2 first, and then the elastic element 3 can be compressed and inserted into the receiving groove 15. The limiting member can limit the end of the elastic element 3, stably restricting the elastic element 3 within the receiving groove 15, preventing it from popping out of the opening of the receiving groove 15 when the garment processing device is working. The limiting member can ensure the reliability and stability of the garment processing device.

[0052] Continue to refer to Figure 2 As shown, the limiting member includes a first limiting member 16, which is disposed on the movable member 1 and is arranged circumferentially on the outer side of the first end of the elastic member 3.

[0053] Continue to refer to Figure 2As shown, a contact portion 21 extends from the fixing member 2 into the receiving groove 15, and the contact portion 21 abuts against the second end of the elastic member 3; the elastic member 3 is a cylindrical spring, and the limiting member includes a second limiting member 22 disposed on the contact portion 21. The second limiting member 22 is a cylindrical structure, and the second limiting member 22 is inserted into the second end of the elastic member 3; it should be understood that both the second limiting member 22 and the first limiting member 16 are used to provide reliable support for the end of the elastic member 3 and to achieve the limiting structure of the elastic member 3. The first limiting member 16 and the second limiting member 22 are both matched with the shape of the end of the elastic member 3, thereby ensuring that the elastic member 3 can more stably complete the shortening and elongation action in the receiving groove 15, and is not prone to displacement after multiple elastic deformations.

[0054] In some embodiments, one of the first limiting member 16 and the second limiting member 22 is an annular structure sleeved around the periphery of the end of the elastic member 3, and the other is a cylindrical structure inserted into the inner side of the end of the elastic member 3. This arrangement can ensure that both ends of the elastic member 3 of the cylindrical spring structure can be well fixed and stabilized, further preventing the elastic member 3 from shifting in the receiving groove 15 and from snapping, significantly reducing the failure rate of the clothing processing device. At the same time, it can also make at least one end of the elastic member 3 exposed in the receiving groove 15, which can make it easier to install and remove the elastic member 3. It should be understood that when installing and removing the elastic member 3, it is only necessary to first compress the elastic member 3, and then let the two ends of the elastic member 3 separate from the second limiting member 22 and the first limiting member 16 in sequence or separate from the first limiting member 16 and the second limiting member 22 in sequence. By setting one of the first limiting member 16 and the second limiting member 22 as an annular structure and the other as a cylindrical structure, the end of the elastic member 3 connected to the cylindrical structure is on the outside, which makes it easier to compress its end.

[0055] In a further embodiment, the inner diameter of the elastic member 3 matches the diameter of the second limiting member 22; this arrangement allows the second limiting member 22 to better fix the end of the elastic member 3 of the cylindrical spring structure; it should be noted that the second limiting member 22 can be a cylindrical structure or a prism structure, as long as it can fix the end of the elastic member 3; it should be understood that the end of the second limiting member 22 can be chamfered, which makes it easier for the elastic member 3 to be fitted onto the second limiting member 22.

[0056] Continue to refer to Figure 8As shown, the limiting member also includes a third limiting member 7, which is disposed on the movable member 1 and / or the fixed member 2. The third limiting member 7 abuts against the outer side of the middle part of the elastic member 3. There can be two sets of third limiting members 7, which can be disposed on the movable member 1 and the fixed member 2 at the same time. The two sets of third limiting members 7 on the movable member 1 and the fixed member 2 are disposed opposite to each other along the radial direction of the elastic member 3, and support the radial direction of the elastic member 3 at the same time. It should be noted that the two sets of third limiting members 7 can be disposed at the opening of the receiving groove 15, so as to support the radial direction of the elastic member 3, prevent its deformation, and prevent it from falling out of the receiving groove 15.

[0057] Continue to refer to Figure 2 As shown, the second end of the receiving groove 15 is sealed, and the second limiting member 22 is located inside the receiving groove 15. This arrangement allows the second limiting member 22 to stabilize the end of the elastic member 3 while also limiting the movable member 1. When the movable member 1 slides to the state where the seal of the receiving groove 15 abuts against the second limiting member 22, the movable member 1 cannot continue to slide, thereby preventing the movable member 1 from slipping out of the fixing member 2. This further improves the reliability and safety of the clothing processing device and significantly reduces the failure rate of the clothing processing device.

[0058] In some embodiments, the elastic element 3 is compressed and disposed in the receiving groove 15. When the drain hole is completely closed, the second limiting element 22 is located at the end of the receiving groove 15 on the side with the first sealing opening. It should be understood that the elastic element 3 can be a compression spring. When the elastic element 3 is a compression spring, when installing the elastic element 3 in the receiving groove 15, it is only necessary to first compress the elastic element 3 to a certain stroke, then place it in the receiving groove 15, and then release the elastic element 3 to return it to its original shape. The two ends abut against the first limiting element 16 and the second limiting element 22 respectively. The installation is very convenient, making the assembly efficiency of the clothing processing device higher.

[0059] In some embodiments, the first limiting member 16 and the movable member 1 are integrally formed; that is, the first limiting member 16 and the movable member 1 are integrally formed by casting or other processing methods. This arrangement can make the connection between the first limiting member 16 and the movable member 1 more secure and reliable, further reducing the risk of the elastic member 3 flying out of the receiving groove 15. Moreover, the first limiting member 16 can be set as a ring structure, a plate structure, a block structure, etc. to close the opening of the receiving groove 15, as long as it can restrict the elastic member 3.

[0060] In a further embodiment, the fixed member 2 is provided with a sliding groove, and the movable member 1 and the sliding groove are both concentric arc-shaped structures. The movable member 1 is slidably disposed in the sliding groove. The first end of the movable member 1 is provided with a counterweight 6. The sliding groove arches towards the center of the inner cylinder. When the second end of the movable member 1 closes the drain hole, the center of gravity of the counterweight 6 and the second end of the movable member 1 are located on both sides of the innermost end of the sliding groove. It should be understood that the arc center of the movable member 1 and the axis of the inner cylinder are perpendicularly connected to form a first connecting line. When the second end of the movable member 1 closes the drain hole, the center of gravity of the counterweight 6 and the second end of the movable member 1 are located on both sides of the first connecting line. That is to say, when the drain hole is completely closed, the rotation of the inner cylinder can provide centrifugal force to the counterweight 6, and this centrifugal force can drive the counterweight 6 to slide towards the end of the sliding groove near the first end of the movable member 1, thereby driving the sealing ring 5 away from the drain hole and realizing the action of opening the drain hole.

[0061] In some embodiments, the innermost end of the chute is provided with a second seal. When the drain hole is fully open, the first end of the movable member 1 is located at the end of the chute on the side where the second seal is provided. By providing the second seal, the movable member 1 can be limited when it is opened, preventing it from moving too far away from the drain hole and affecting its opening and closing response speed.

[0062] Continue to refer to Figures 1 to 7 As shown, the drain valve also includes a sealing ring 5 and a pressure plate 4. The periphery of the sealing ring 5 forms a sealable fit with the drain hole. That is, when the sealing ring 5 is at the drain hole, it can seal the drain hole and close it. When the sealing ring 5 is removed from the drain hole, the drain hole opens. The sealing ring 5 is provided with a first pressure relief port 521. The pressure plate 4 elastically abuts against the sealing ring 5 and closes the first pressure relief port 521. The pressure plate 4 is connected to the movable part 1.

[0063] The sealing ring 5 is located at the drain hole and is used to seal the drain hole, thereby ensuring the sealing state of the inner cylinder of the clothing processing device. When the pressure inside the inner cylinder of the clothing processing device reaches the set value, the part of the pressure plate 4 and the sealing ring 5 that elastically abuts will begin to deform, creating a gap. At this time, some liquid flows through the gap and flows out from the first pressure relief port 521, thereby realizing the pressure relief action. This can ensure the good sealing performance of the clothing processing device and the stability of the internal environment of the inner cylinder of the clothing processing device. It can also relieve pressure in time when high pressure occurs, which significantly improves the practicality and safety of the clothing processing device.

[0064] In some embodiments, the sealing ring 5 includes an annular sealing ring body 51 and a sealing plate 52 disposed at the central hole of the sealing ring body 51. A first pressure relief port 521 is opened on the sealing plate 52. The pressure plate 4 abuts against the side of the sealing plate 52 facing the washing chamber. The sealing plate 52 is elastic. A second pressure relief port 41 is opened on the pressure plate 4. The second pressure relief port 41 is offset from the first pressure relief port 521 (the projection of the second pressure relief port 41 on the sealing plate 52 is offset from the first pressure relief port 521).

[0065] The sealing plate 52 provides a reliable seal for the drain hole. Furthermore, the first pressure relief port 521 on the elastic sealing plate 52, and the pressure plate 4 attached to the side of the sealing plate 52 facing the washing chamber, allow the liquid in the washing chamber to press against the pressure plate 4 when the liquid pressure does not reach the set value, thus sealing the first pressure relief port 521. It should be noted that the pressure plate 4 is positioned directly opposite the first pressure relief port 521, while the second pressure relief port 41 on the pressure plate 4 is offset from the first pressure relief port 521. Liquid in the inner drum of the garment processing device first flows from the second pressure relief port 41 into the gap between the sealing plate 52 and the pressure plate 4, and then flows out from the first pressure relief port 521. This fully utilizes the gap between the sealing plate 52 and the pressure plate 4 to achieve sealing and pressure relief, ensuring good sealing of the garment processing device, maintaining a stable internal environment, and timely pressure relief in case of high pressure, further improving the practicality and safety of the garment processing device.

[0066] In some embodiments, the first pressure relief port 521 is in a closed state under natural conditions. It should be understood that the first pressure relief port 521 can be formed by cutting on the sealing ring 5. It utilizes the liquid pressure inside the inner drum of the garment processing device to push the sealing ring 5 to deform at the first pressure relief port 521, thereby opening the first pressure relief port 521 and realizing the pressure relief action. When the liquid pressure inside the inner drum of the garment processing device does not reach the set value, the first pressure relief port 521 returns to a closed structure under the elastic action of the sealing ring 5 itself. This setting can effectively prevent pollutants in the external environment from entering the first pressure relief port 521 and affecting the opening and closing action of the first pressure relief port 521.

[0067] Continue to refer to Figures 5 to 7 As shown, the first pressure relief port 521 is a straight structure; setting the first pressure relief port 521 as a straight structure not only makes it easier to process, but also enables faster opening and closing actions, strengthens the overall structure, and makes it easier to achieve complete closure, resulting in a better sealing effect under natural conditions; the first pressure relief port 521 can also be a round hole structure, a square hole structure, a polygonal hole structure, or a scattering hole structure formed by combining multiple straight structures rotating circumferentially.

[0068] In some embodiments, the number of second pressure relief ports 41 can be multiple. In a further embodiment, the number of second pressure relief ports 41 is two, and the two second pressure relief ports 41 are symmetrical about the center of the first pressure relief port 521. This arrangement ensures that the first pressure relief port 521 with a linear structure experiences the same force during pressure relief, thereby improving the service life of the sealing plate 52. It also ensures that the liquid flowing from the two second pressure relief ports 41 to the first pressure relief port 521 has the same velocity, thereby further improving the stability during pressure relief. In a further embodiment, the line connecting the two second pressure relief ports 41 is perpendicular to the extension direction of the first pressure relief port 521. This arrangement of the two second pressure relief ports 41 and the first pressure relief port 521 with a linear structure not only allows the first pressure relief port 521 and the second pressure relief port 41 to be misaligned, but also facilitates precise positioning when installing the pressure plate 4, significantly improving the assembly efficiency of the clothing processing device.

[0069] In a further embodiment, the pressure plate 4 is made of a rigid material. It should be understood that the material used for the pressure plate 4 will not be significantly deformed by the pressure inside the inner drum of the garment processing device. By placing the pressure plate 4 on the side of the sealing ring 5 facing the washing chamber, when the pressure inside the inner drum of the garment processing device reaches a set value, the liquid pushes the sealing ring 5 from the second pressure relief port 41, causing the sealing ring 5 to bulge outward and forming a gap between it and the pressure plate 4 for liquid to flow. This ensures the reliability of the garment processing device during the pressure relief action and prevents the pressure plate 4 and the sealing ring 5 from being pressed down by the liquid, thus preventing the formation of a flow gap and the first pressure relief port 521 from opening.

[0070] In some embodiments, there are multiple first pressure relief ports 521 and / or multiple second pressure relief ports 41. By setting multiple first pressure relief ports 521 and second pressure relief ports 41, the cross-sectional area of ​​the sealing plate 52 and the pressure plate 4 can be utilized more fully to discharge the same volume of liquid. This allows for smaller deformation of each first pressure relief port 521 and a faster response. At the same time, this arrangement can also reduce the probability of damage to the clothing processing device due to excessive local stress, further improving the reliability of the clothing processing device and extending its service life.

[0071] Continue to refer to Figure 7As shown, the sealing ring 5 is provided with a groove 53, the shape of which matches the shape of the pressure plate 4, and the pressure plate 4 is embedded in the groove 53. It should be understood that the groove 53 is an annular groove. When the pressure plate 4 is a circular plate, the edge of the groove 53 can be circular. When the pressure plate 4 is a polygonal plate, the edge of the groove 53 can be polygonal. This can ensure that the pressure plate 4 is stably fixed on the sealing ring 5. Furthermore, when both the pressure plate 4 and the groove 53 are polygonal or other irregular shapes, it can also prevent the pressure plate 4 from rotating relative to the sealing ring 5. It should be noted that both ends of the groove 53 along its axial direction are provided with end faces that restrict the pressure plate 4. The installation of the pressure plate 4 requires the deformation of the sealing ring 5 itself.

[0072] In some embodiments, the limiting part 54 elastically abuts against the pressure plate 4; by providing the limiting part 54, the pressure plate 4 can be provided with an elastic force to press against the sealing plate 52, ensuring the sealing performance of the drain valve when the pressure relief condition is not met.

[0073] Continue to refer to Figure 5 As shown, the second pressure relief port 41 is located at the edge of the pressure plate 4; this design makes the second pressure relief port 41 easier to process and easier to install and remove the pressure plate 4. The pressure plate 4 can be more easily installed into or removed from the slot 53 by utilizing its opening and the elasticity of the sealing ring 5.
