[0002] In the field of textiles, the finishing desizing, union bleaching, mercerization and washing process usually uses a washing box to load and clean the fabric. The fabric is loaded and cleaned by running through the washing box liquid through the running of the guide roller immersed in the liquid, so as to achieve the purpose of loading and cleaning. The washing box needs to be sealed during use. The sealing device in the prior art relies on the resilience of the elastic locking member to make the sealing sleeve and the sealing component tightly contact to achieve waterproof sealing. The above sealing device is prone to the following problems: (1) since the elastic locking member relies on the resilience of the elastic locking member to achieve waterproof sealing, the softness changes after a period of use, which reduces the sealing effect and causes leakage; (2) during production, the washing box is prone to have slurry, yarn and other impurities, which are easily brought to the end face of the guide roller during rotation and penetrate into the sealing elastic locking member, thereby reducing the sealing effect and causing leakage. CONTENT OF THE UTILITY MODEL
[0003] Therefore, it is necessary to provide a telescopic and resilient waterproof sealing device. The telescopic and resilient waterproof sealing device has strong universality, good waterproof sealing effect and long service life, and is generally applicable to the sealing of water tanks with rotating shafts, and is particularly applicable to the sealing of functional boxes used in the finishing process of the textile industry.

[0006] In some embodiments, the pressing component comprises an elastic member and an elastic positioning sleeve, the elastic positioning sleeve is used to be fixed on the rotating shaft, the elastic member is used to be sleeved on the rotating shaft, the elastic member is located in the elastic positioning sleeve, and the elastic member is in a compressed state to press the sealing component.

[0008] In some embodiments, a part of the pressing sleeve is embedded in the elastic positioning sleeve.
[0009] In some embodiments, one end of the pressing sleeve towards the elastic member has a boss structure, and the elastic member is matched with the boss structure on the pressing sleeve.
[0010] In some embodiments, the elastic member is a compression spring.
[0011] In some embodiments, the sealing sleeve is provided with a first sleeve hole, and the sealing sleeve is fixedly connected with the rotating shaft by being penetrated by a fastener through the first sleeve hole.

[0016] The above-mentioned telescopic and resilient waterproof sealing device improves the sealing effect by adding a pressing part at the shaft end.

[0031] The present application provides a retractable and resilient waterproof sealing device 100 to address at least one of the following problems that are common with existing sealing devices: (1) Since the elastic locking member 110 primarily relies on the resilience generated by the softness of its own diaphragm to achieve waterproof sealing, its softness changes after a period of use, reducing the sealing effect and thus easily causing leakage; (2) During the production process, slurry, yarn, and other debris are easily present in the washing box. During the rotation of the cloth guide roller, slurry, yarn, and other debris are easily transferred to the end surface of the cloth guide roller and penetrate into the sealing elastic locking member 110, thereby reducing the sealing effect and causing leakage. The retractable and resilient waterproof sealing device 100 will be described below with reference to the accompanying drawings.
[0032] The retractable and resilient waterproof sealing device 100 provided in the embodiment of the present application is illustrative. Figure 1 As shown, Figure 1 Schematic diagram of the structure of the retractable and resilient waterproof sealing device 100 provided in an embodiment of the present application. The retractable and resilient waterproof sealing device 100 of the present application can be used for sealing a functional box 10 such as a washing box.
[0033] In order to more clearly illustrate the structure of the retractable and resilient waterproof sealing device 100 , the retractable and resilient waterproof sealing device 100 will be introduced below with reference to the accompanying drawings.
[0034] For example, see Figure 1 As shown, a retractable and resilient waterproof sealing device 100 includes an elastic locking member 110, a sealing sleeve 120, a sealing component 130, a compression sleeve 140 and a compression component. The sealing sleeve 120 and the sealing component 130 are respectively used to be fixed on the rotating shaft 300 and abut against each other. A part of the elastic locking member 110 is used to be connected to the box body 200 to be sealed and the other part is connected to the sealing component 130. The sealing sleeve 120 squeezes the sealing component 130 and generates a force on the elastic locking member 110. The compression sleeve 140 is used to be mounted on the rotating shaft 300 and contact the sealing component 130. The compression sleeve 140 and the sealing sleeve 120 are respectively located on both sides of the sealing component 130. The compression component is used to be connected to the rotating shaft 300. The compression component applies pressure to the compression sleeve 140 to achieve compression of the compression sleeve 140 and close contact with the sealing component 130. The retractable and resilient waterproof sealing device 100 of the present application can be used for dynamic sealing between the rotating shaft 300 and the box body 200 .
[0035] In some embodiments, the compression component includes an elastic member 150 and an elastic positioning sleeve 160. The elastic positioning sleeve 160 is configured to be fixed to the rotating shaft 300. The elastic member 150 is configured to be sleeved on the rotating shaft 300. The elastic member 150 is located in the elastic positioning sleeve 160. The elastic member 150 is in a compressed state to achieve compression on the sealing component 130. The present application separates the waterproof sealing from the sundries by the elastic positioning sleeve 160, avoiding the gap between the elastic locking member 110 and the sealing component 130 from being reduced or failed due to the sundries.
[0036] In some embodiments, the sealing component 130 can be a sealing carbon. The "sealing carbon" is generally made of high-purity carbon material, and the carbon has special properties, such as a certain strength. In the present application, the sealing component 130 is used for dynamic sealing of the rotating shaft 300. The sealing carbon can improve the service life of the sealing component 130.
[0037] In some embodiments, the elastic locking member 110 can be a rubber pad. The "rubber pad" refers to a rubber gasket or a rubber plate used for sealing, insulation or other functions. For example, the elastic locking member 110 in the present application is designed with a rubber pad, which is convenient for processing. See Figure 1 As shown, the elastic locking member 110 can have a cap shape, a horn shape, etc., which mainly provides a movable elastic restoring force.
[0038] In some embodiments, the elastic positioning sleeve 160 is provided with a second sleeve hole 161. The elastic positioning sleeve 160 is fixedly connected to the rotating shaft 300 by being threaded through the second sleeve hole 161 by a fastener.
[0039] In some embodiments, part of the compression sleeve 140 is embedded in the elastic positioning sleeve 160. The arrangement that part of the compression sleeve 140 is embedded in the elastic positioning sleeve 160 can improve the sealing performance between the compression sleeve 140, the sealing component 130 and the sealing sleeve 120.
[0040] In some embodiments, one end of the compression sleeve 140 towards the elastic member 150 has a boss structure, and the elastic member 150 cooperates with the boss structure on the compression sleeve 140. The arrangement of the boss structure can achieve cooperation between the elastic member 150 and the compression sleeve 140, and can also achieve detachability between the elastic member 150 and the compression sleeve 140.
[0041] In some embodiments, the elastic member 150 is a compression spring. It is not difficult to understand that the elastic member 150 can also be an elastic rubber block.
[0042] Preferably, in some embodiments, the elastic member 150 is a linear compression spring, which is one of the most common types of springs. When subjected to external pressure, it compresses axially and returns to its original shape after the pressure is removed.
[0043] In some embodiments, when the elastic member 150 is a compression spring, the elastic positioning sleeve 160 is a spring positioning sleeve.
[0044] In some embodiments, the sealing sleeve 120 is provided with a first sleeve hole 121, and the sealing sleeve 120 is fixedly connected to the rotating shaft 300 by a fastener passing through the first sleeve hole 121.
[0045] In some embodiments, the above-mentioned fastener can be a fastening bolt. The setting of the fastener enables the sealing sleeve 120 and the elastic positioning sleeve 160 to be detachable from the rotating shaft 300.
[0046] In some embodiments, a clamping groove 131 is provided on the outer peripheral wall of the sealing member 130. The elastic locking member 110 has an annular structure. The inner edge of the elastic locking member 110 is clamped in the clamping groove 131, and the outer edge of the elastic locking member 110 is used to be fixed on the box body 200.
[0047] In some embodiments, referring to Figure 1 As shown, the elastic locking member 110 has an annular cylindrical structure. The inner opening diameter of the elastic locking member 110 cooperating with the sealing member 130 is smaller than the inner opening diameter of the elastic locking member 110 cooperating with the box body 200. The portion between the two openings of the elastic locking member 110 has a curved surface structure, so as to ensure that the elastic locking member 110 has a certain elastic restoring force. Preferably, one end of the elastic locking member 110 cooperating with the box body 200 has a first contact portion flush with the box body 200, so that the elastic locking member 110 is generally in an approximate "J" - shaped structure. The structure of the elastic locking member 110 can ensure that the elastic locking member 110 has a certain elastic restoring force. Preferably, one end of the elastic locking member 110 cooperating with the sealing member 130 has a second contact portion flush with the bottom surface of the clamping groove 131, and the second contact portion can cooperate tightly with the clamping groove 131 to prevent the elastic locking member 110 from moving. Preferably, after the telescopic and resilient waterproof sealing device 100 cooperates with the box body 200 and the rotating shaft 300, since the axial direction of the rotating shaft 300 is perpendicular to the box wall of the box body 200 and the bottom surface of the clamping groove 131 is consistent with the axial direction of the rotating shaft 300, the plane where the first contact portion is located and the plane where the second contact portion is located are perpendicularly arranged.
[0048] In some embodiments, the sealing sleeve 120 is an elastic rubber sleeve. The sealing sleeve 120 has an overall annular structure. The sealing sleeve 120 has a certain thickness and width.
[0049] The embodiment of the present application further provides a functional box 10.
[0050] The functional box 10 comprises a box body 200, a rotating shaft 300 and the above-mentioned waterproof sealing device 100. The rotating shaft 300 is partially located in the box body 200 and partially extends out of the box body 200. The elastic locking member 110 of the waterproof sealing device 100 is partially connected to the outer wall of the box body 200 and partially connected to the sealing member 130. The sealing sleeve 120 and the sealing member 130 are respectively sleeved and fixed on the rotating shaft 300 and abut against each other. The pressing sleeve 140 is sleeved on the rotating shaft 300 and contacts the sealing member 130. The pressing sleeve 140 is respectively located on the two sides of the sealing member 130. The pressing member is connected to the rotating shaft 300 to apply pressure to the pressing sleeve 140 to realize the pressing of the pressing sleeve 140 and the close contact of the pressing sleeve 140 with the sealing member 130.
[0051] In some embodiments, the functional box 10 can be a washing box, a cleaning box, a dyeing box and the like.
[0052] In summary, the waterproof sealing device 100 can improve the sealing effect by adding the pressing member at the shaft end. The sealing state mainly depends on the contact degree of the sealing sleeve 120 and the sealing member 130. The elastic locking member 110 makes the sealing member 130 and the sealing sleeve 120 contact closely to achieve the sealing purpose. With the increase of the use time of the elastic locking member 110, the softness of the diaphragm of the elastic locking member 110 becomes poor, the diaphragm becomes hard and the elasticity becomes poor. When the diaphragm of the elastic locking member 110 cannot make the sealing member 130 and the sealing sleeve 120 contact closely, a gap will be formed between the sealing member 130 and the sealing sleeve 120, thereby forming leakage. To this end, the pressing member extrudes the pressing sleeve 140, the pressing sleeve 140 extrudes the sealing member 130, the sealing sleeve 120 and the sealing member 130 are in close contact, the pressing sleeve 140 has a certain elastic force on the carbon point of the elastic locking member 110, thereby achieving good compensation effect and good waterproof sealing effect. The device has strong universality, good waterproof sealing effect and long service life, and is generally applicable to the occasions where the rotating shaft is in the water tank, and is particularly suitable for the functional box 10 used in the finishing of the textile industry.
[0053] In the above-mentioned embodiments, the description of each embodiment has its own emphasis. The parts not described in detail in a certain embodiment can be referred to the related description of other embodiments.
[0054] Any combination of the technical features in the above-described embodiments can be made, and for the sake of brevity, not all possible combinations are described, however, as long as the combination of the technical features does not exist in contradiction, it shall be considered as within the scope of the present disclosure.
[0055] The above-described embodiments only express several implementation manners of the present application, the description is relatively specific and detailed, but it shall not be understood as a limitation on the patent scope of the present application. It should be pointed out that, for ordinary skilled persons in the art, under the premise of not departing from the concept of the present application, a number of modifications and improvements can be made, which all belong to the protection scope of the present application.
