Technical Field
[0001] This utility model relates to the field of cleaning equipment technology, and in particular to a rotating locking mechanism. Background Technology
[0002] Mops are the most commonly used cleaning equipment. Users can use mops to clean floors, walls, or glass. However, due to the different angles of the surfaces that need to be cleaned depending on the user's height, it is necessary to adjust the angle of the mop handle and the cleaning surface to make the cleaning surface fit the ground better and thus improve cleaning efficiency. However, the connection position between the handle and the cleaning surface in the existing technology cannot be locked, which affects the user's operating difficulty and cleaning efficiency. Therefore, a rotating locking mechanism is needed. Utility Model Content
[0003] To address the problem of the inability to lock the connection between the grip and the cleaning surface, this utility model provides a rotating locking mechanism, the specific technical solution of which is as follows:
[0004] A rotary locking mechanism includes a connecting handle, a rotating head, and a control and adjustment assembly. The lower end of the connecting handle has an upper hinge portion, which includes a first mounting block and a second mounting block arranged parallel to each other and spaced apart. The gap between the first and second mounting blocks forms a mating groove. The first and second mounting blocks have upper hinge holes. The first mounting block has a first sliding groove on its side away from the second mounting block, and the second mounting block has a second sliding groove on its side away from the first mounting block. The upper end of the rotating head has a lower hinge portion, which has a lower hinge hole. The lower hinge portion is rotatably positioned within the mating groove. The upper hinge hole and... The lower hinge hole is coaxially arranged, and an adjustment groove is provided around the lower hinge hole on the side near the first mounting block. The control and adjustment assembly includes a first control part, a middle control part, and a second control part. The middle control part is disposed between the first control part and the second control part. The middle control part is slidably disposed in the upper hinge hole and the lower hinge hole. The first control part is slidably embedded in the first sliding groove, and the second control part is slidably embedded in the second sliding groove. An adjustment protrusion that matches the adjustment groove is provided on the side of the first control part near the lower hinge part. Pressing the first mounting block causes the adjustment protrusion to be embedded in the adjustment groove, and pressing the second mounting block causes the adjustment protrusion to be separated from the adjustment groove.
[0005] In some embodiments, the control and adjustment component has a split structure.
[0006] In some embodiments, the outer wall of the central control unit is provided with an elastic limiting card, and the inner side of the second sliding groove is provided with a limiting slot that matches the elastic limiting card. Pressing the first mounting block causes the elastic limiting card to be embedded in the limiting slot.
[0007] In some embodiments, anti-jamming blocks are provided at equal intervals around the inner periphery of the first sliding groove.
[0008] In some embodiments, the surfaces of the first control unit and the second control unit are coated with different colored coatings.
[0009] In some embodiments, the first control unit and the second control unit are circular disc structures with the same diameter, and the middle control unit is cylindrical.
[0010] Compared with the prior art, the present invention has the following beneficial effects:
[0011] Firstly, in this solution, the lower end of the connecting handle is provided with an upper hinge portion, which includes a first mounting block and a second mounting block arranged parallel to each other and spaced apart. The gap between the first mounting block and the second mounting block forms a mating groove. The first and second mounting blocks are provided with upper hinge holes. The first mounting block has a first sliding groove on the side away from the second mounting block, and the second mounting block has a second sliding groove on the side away from the first mounting block. The upper end of the rotating head is provided with a lower hinge portion, which has a lower hinge hole. The lower hinge portion is rotatably disposed within the mating groove. The upper hinge hole and the lower hinge hole are coaxially arranged. The lower hinge hole has an adjustment groove circumferentially arranged on the side near the first mounting block. The control and adjustment assembly includes a first control unit, a middle control unit, and a second control unit. The middle control unit... The middle control unit is slidably disposed between the first control unit and the second control unit, and is slidably disposed in the upper hinge hole and the lower hinge hole. The first control unit is slidably embedded in the first sliding groove, and the second control unit is slidably embedded in the second sliding groove. An adjustment protrusion that matches the adjustment groove is provided on the side of the first control unit near the lower hinge unit. When the user needs to adjust the setting angle of the rotating head, he presses the second mounting block to separate the adjustment protrusion from the adjustment groove. At this time, the user holds the connecting handle and rotates the rotating head around the control adjustment component as the axis to adjust the angle. When the rotating head is adjusted to the appropriate angle, the first mounting block is pressed to make the adjustment protrusion embedded in the adjustment groove. At this time, the control adjustment component locks the matching angle of the connecting handle and the rotating head, so that the user can hold the connecting handle to control the cleaning tool on the rotating head to perform cleaning operations.
[0012] Secondly, this solution has an elastic limiting clip on the outer wall of the central control unit, and a limiting slot that matches the elastic limiting clip on the inner side of the second sliding groove. Pressing the first mounting block causes the elastic limiting clip to be embedded in the limiting slot. The cooperation between the elastic limiting clip and the limiting slot can limit the position of the control adjustment component, preventing the control adjustment component from sliding and affecting the normal use of the cleaning tool when the rotating locking mechanism is operated and moved.
[0013] Thirdly, the surfaces of the first and second control units are coated with different colored coatings. These different colored coatings can indicate to the user the current setting position of the control and adjustment components. Based on this, the user can quickly control and adjust the rotating locking mechanism according to their needs. Attached Figure Description

[0029] like Figures 1 to 7 As shown, a rotating locking mechanism includes a connecting handle 1, a rotating head 2, and a control and adjustment component 3. In use, a grip can be installed on the connecting handle 1, and a cleaning component can be installed on the rotating head 2. The control and adjustment component 3 controls and limits the connection between the connecting handle 1 and the rotating head 2, thereby forming a fixed angle between the connecting handle 1 and the rotating head 2 to facilitate cleaning operations.
[0030] In some embodiments, the lower end of the connecting handle 1 is provided with an upper hinge portion 11. The upper hinge portion 11 includes a first mounting block 111 and a second mounting block 112 that are parallel to each other and spaced apart. The gap between the first mounting block 111 and the second mounting block 112 forms a fitting groove 113. The first mounting block 111 and the second mounting block 112 are provided with upper hinge holes 114. The first mounting block 111 is provided with a first sliding groove on the side away from the second mounting block 112, and the second mounting block 112 is provided with a second sliding groove on the side away from the first mounting block 111.
[0031] In some embodiments, the upper end of the rotating head 2 is provided with a lower hinge portion 21, the lower hinge portion 21 is provided with a lower hinge hole 211, the lower hinge portion 21 is rotatably disposed in the fitting groove 113, the upper hinge hole 114 and the lower hinge hole 211 are coaxially disposed, and an adjustment groove 2111 is provided around the lower hinge hole 211 on the side near the first mounting block 111.
[0032] In some embodiments, the control and adjustment assembly 3 includes a first control part 31, a middle control part 32, and a second control part 33. The middle control part 32 is disposed between the first control part 31 and the second control part 33. The middle control part 32 is slidably disposed in the upper hinge hole 114 and the lower hinge hole 211. The first control part 31 is slidably embedded in the first sliding groove, and the second control part 33 is slidably embedded in the second sliding groove. An adjustment protrusion 311 that engages with the adjustment groove 2111 is provided on the side of the first control part 31 near the lower hinge part 21.
[0033] like Figure 4 and Figure 5 As shown, when the user needs to adjust the setting angle of the rotating head 2, press the second mounting block 112 to separate the adjusting protrusion 311 from the adjusting groove 2111. At this time, the user holds the connecting handle 1 and rotates the rotating head 2 around the control adjustment component 3 to adjust the angle. When the rotating head 2 is adjusted to the appropriate angle, press the first mounting block 111 to make the adjusting protrusion 311 fit into the adjusting groove 2111. At this time, the control adjustment component 3 locks the matching angle between the connecting handle 1 and the rotating head 2, so that the user can hold the connecting handle 1 to control the cleaning tool on the rotating head 2 to perform cleaning operations.
[0034] In some embodiments, the control and adjustment component 3 is a split structure, which facilitates the assembly and processing of the rotary locking mechanism.
[0035] Optionally, the first control unit 31 extends outward from the side near the second control unit 33 to form an outer splicing part, which is provided with a splicing groove. An inner splicing part is provided on the side of the second control unit 33 near the first control unit 31, which is embedded inside the outer splicing part. A splicing component is provided on the inner splicing part, and the splicing component fits into the splicing groove. The outer splicing part and the inner splicing part are spliced together to realize the assembly of the control adjustment component 3. The outer splicing part and the inner splicing part constitute the control unit 32 in the control adjustment component 3.
[0036] In some embodiments, the outer wall of the control unit 32 is provided with an elastic limiting member 321, and the inner side of the second sliding groove is provided with a limiting groove 1121 that matches the elastic limiting member 321. Pressing the first mounting block 111 causes the elastic limiting member 321 to be embedded in the limiting groove 1121. The cooperation between the elastic limiting member 321 and the limiting groove 1121 can limit the position of the control adjustment component 3, preventing the control adjustment component 3 from sliding and affecting the normal use of the cleaning tool during operation and movement of the rotating locking mechanism.
[0037] In some embodiments, anti-jamming blocks 1111 are provided at equal intervals around the inner periphery of the first sliding groove. The anti-jamming blocks 1111 can prevent the control adjustment component 3 from rotating in the first sliding groove, thus affecting the subsequent adjustment of the control adjustment component 3 in the first and second sliding grooves.
[0038] In some embodiments, the surfaces of the first control unit 31 and the second control unit 33 are coated with different colored coatings. The different colored coatings can indicate to the user the current setting position of the control adjustment component 3. Based on this, the user can quickly control and adjust the rotating locking mechanism according to their needs.
[0039] In some embodiments, the first control unit 31 and the second control unit 33 are circular disc structures with the same diameter, and the middle control unit 32 is cylindrical, thereby improving the adjustment fit of the control adjustment assembly 3 in the connecting handle 1 and the rotating head 2.
[0040] The technical principles of this utility model have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this utility model without inventive effort, and these embodiments will all fall within the protection scope of the claims of this utility model.
