Description

Technical Field

[0001] This utility model relates to the field of fabric machine technology, and more specifically, to a rotating connection structure between a fabric machine hose connector and a cleaning head. Background Technology

[0002] A fabric cleaning machine is a device used to clean dirt from the surface of fabric items. The cleaning head is an important component of the machine, connected to the main body via a flexible hose. In traditional fabric cleaning machine structures, the handle and hose within the cleaning head have two connection methods: one is a fixed connection that cannot rotate. The advantage of this is that the cleaning head and hose cannot rotate relative to each other, ensuring vacuum during wastewater suction and preventing leaks. However, this also limits the operating angle; changing the cleaning head's direction will cause the hose to twist, making it extremely inconvenient to use. The second method allows for 360-degree infinite rotation between the cleaning head and hose. While this allows for multi-angle cleaning, the hose contains steam pipes and connecting wires. Infinite rotation of the cleaning head relative to the hose can cause knots or excessive twisting of these components, potentially leading to breakage. Therefore, there is an urgent need for a rotating connection structure between the fabric machine hose connector and the cleaning head that allows the cleaning head to rotate relative to the hose while preventing excessive twisting of the steam pipes and connecting wires. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a rotating connection structure between the hose connector and the cleaning head of a fabric machine. This structure not only meets the cleaning needs of the cleaning head being able to rotate at multiple angles relative to the hose, but also avoids the situation where the steam pipe and connecting wire in the hose are excessively twisted due to the cleaning head continuously rotating in one direction relative to the hose.

[0004] This utility model provides a rotary connection structure for a fabric knitting machine hose connector and a cleaning head, including a hose connector and a cleaning head body; the hose connector is connected to the lower end of the handle in the cleaning head body; the rotary connection structure also includes a limiting member; the upper end of the hose connector is coaxially provided with an annular insertion part with an outer diameter smaller than the hose connector; an annular groove is provided on the outer peripheral wall of the annular insertion part, and the limiting member is rotatably engaged with the annular groove and used to limit the angle range of the hose connector relative to the handle, and the limiting member and the annular insertion part are axially limited; the annular insertion part is inserted into the lower end of the handle from bottom to top, and the limiting member and the handle are engaged and circumferentially limited.

[0005] By adopting the above structure, the handle on the cleaning head body and the hose connector connected to the hose can rotate within a certain angle range. This not only meets the cleaning needs of the cleaning head being able to rotate relative to the hose at multiple angles, but also avoids the situation where the steam pipe and connecting wire in the hose are excessively twisted due to the cleaning head continuously rotating relative to the hose in one direction.

[0006] In one possible implementation, the limiting member includes a "C"-shaped locking portion that engages with an annular groove. Two limiting protrusions, evenly distributed circumferentially around the locking portion, are provided on the upper edge of the locking portion, and two limiting blocks, evenly distributed circumferentially around the annular groove, are provided on the upper edge of the annular groove. When the hose connector rotates relative to the handle, the two limiting protrusions and two limiting blocks alternately abut against each other to limit the range of angles the hose connector can rotate relative to the handle. With this structure, after the locking portion engages with the annular groove, the limiting... The component can be reliably mounted on the annular groove, allowing the hose connector to rotate relative to the limiting component. In addition, under the action of the two limiting bosses and the limiting block, the annular insertion part is inserted into the lower end of the handle from bottom to top. After the limiting component and the handle are engaged, when the hose connector rotates relative to the handle to one side, each limiting boss can eventually abut against the limiting block. When the hose connector rotates relative to the handle to the other side, each limiting boss can eventually abut against the other limiting block, thereby limiting the range of angles in which the hose connector can rotate relative to the handle.

[0007] In one possible implementation, the lower end of the snap-fit ​​portion abuts against the lower end of the annular groove, and the upper ends of the two limiting protrusions abut against the upper end of the annular groove. By adopting this structure, axial limiting of the limiting member and the annular insertion portion is achieved, so that when the annular insertion portion is inserted into the lower end of the handle from bottom to top, and after the limiting member and the handle are engaged, axial limiting of the hose connector and the handle can be achieved.

[0008] In one possible implementation, two locking blocks are provided on the outer side wall of the locking part, which are evenly distributed around the circumference of the locking part. The side wall at the lower end of the handle is provided with locking holes corresponding to the two locking blocks, and each locking block is inserted into the locking hole at the corresponding position. With this structure, the limiting member can reliably engage with the handle and achieve the purpose of circumferential limiting.

[0009] In one possible implementation, the outer wall of the annular insertion part located above the annular groove is provided with several annular grooves spaced apart along the axial direction of the annular insertion part. A sealing ring is embedded in the annular groove, and the hose connector and handle are circumferentially sealed by the sealing ring. By adopting this structure, the circumferential seal between the hose connector and the handle can be achieved under the action of the sealing ring, thereby preventing air leakage and sewage leakage when sewage and air flow through the connection between the hose connector and the handle.

[0017] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0018] See Figure 1-4 As shown in the embodiment of this application, a rotary connection structure for a fabric knitting machine hose connector and a cleaning head is disclosed, including a hose connector 1 and a cleaning head body 2; the hose connector 1 is connected to the lower end of the handle 21 in the cleaning head body 2; the rotary connection structure also includes a limiting member 3; the upper end of the hose connector 1 is coaxially provided with an annular insertion portion 11 with an outer diameter smaller than that of the hose connector 1; an annular groove 111 is provided on the outer peripheral wall of the annular insertion portion 11, and the limiting member 3 is rotatably engaged with the annular groove 111 and used to limit the angle range of the hose connector 1 relative to the handle 21, and the limiting member 3 and the annular insertion portion 11 are axially limited; the annular insertion portion 11 is inserted into the lower end of the handle 21 from bottom to top, and the limiting member 3 and the handle 21 are engaged and circumferentially limited.

[0019] The limiting member 3 includes a "C"-shaped locking part 31, which engages with the annular groove 111. Two limiting protrusions 32, evenly distributed around the circumference of the locking part 31, are provided on the upper edge of the locking part 31. Two limiting blocks 112, evenly distributed around the circumference of the annular groove 111, are provided on the upper edge of the annular groove 111. When the hose connector 1 rotates relative to the handle 21, the two limiting protrusions 32 and the two limiting blocks 112 alternately abut against each other to limit the range of rotation of the hose connector 1 relative to the handle 21. By adopting this structure, the locking part and the annular groove 111... After the shaped groove engages, the limiting member can be reliably locked onto the annular groove, allowing the hose connector to rotate relative to the limiting member. In addition, under the action of the two limiting protrusions and the limiting block, the annular insertion part is inserted into the lower end of the handle from bottom to top. After the limiting member engages with the handle, when the hose connector rotates relative to the handle to one side, each limiting protrusion can eventually abut against one of the limiting blocks. When the hose connector rotates relative to the handle to the other side, each limiting protrusion can eventually abut against the other limiting block, thereby limiting the range of angles in which the hose connector can rotate relative to the handle.

[0020] The lower end of the snap-fit ​​part 31 abuts against the lower end of the annular groove 111, and the upper ends of the two limiting protrusions 32 abut against the upper end of the annular groove 111. By adopting this structure, the axial limiting of the limiting member and the annular plug part is achieved. Thus, when the annular plug part is inserted into the lower end of the handle from bottom to top, and after the limiting member and the handle are engaged, the axial limiting of the hose connector and the handle can be achieved.

[0021] Two locking blocks 33 are evenly distributed around the circumference of the locking part 31 on the outer side wall of the locking part 31. The lower side wall of the handle 21 is provided with locking holes 22 corresponding to the two locking blocks 33. Each locking block 33 is inserted into the corresponding locking hole 22. With this structure, the limiting member can reliably engage with the handle and achieve the purpose of circumferential limiting.

[0022] The outer wall of the annular insertion part 11 located above the annular groove 111 is provided with several annular grooves 113 that are spaced apart along the axial direction of the annular insertion part 111. A sealing ring is embedded in the annular groove 113, and the hose connector 1 and the handle 21 are circumferentially sealed by the sealing ring. With this structure, the circumferential seal between the hose connector and the handle can be achieved under the action of the sealing ring, so that when sewage and air flow through the connection between the hose connector and the handle, air leakage and sewage leakage can be avoided.

[0023] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
