Description

Technical Field

[0001] This utility model relates to the field of cleaning products technology, and in particular to a rod-shaped connector, a multi-section rod, and a cleaning tool. Background Technology

[0002] Multi-section broom or mop handles are a practical design widely used in household cleaning. The core of this design lies in using multiple detachable segments to form a complete cleaning tool handle, providing a more flexible user experience and easier storage. Especially with the prevalence of online shopping, multiple detachable segments facilitate delivery. Conventional segment connection methods include using ribs combined with mortise and tenon joints. However, the ribs can affect the overall strength of the segments and are prone to dimensional errors at the joints, impacting the connection quality; while the mortise and tenon joints result in a less aesthetically pleasing handle.

[0003] In practical use, because the pole segments are usually made of metal, while the joints are made of plastic, as shown in Chinese patent CN213331884U, which discloses a multi-section pole, broom handle and tubular module element, the technical problem of instability of plastic parts is solved by setting a constricted screw connector and an embedded nut connector between the two tubes. However, the two tubes, that is, the pole segments, are still in direct contact at the interface, which will cause mutual wear when fixing the pole segments.

[0004] Especially for broom or mop handles with painted sections for aesthetic purposes, the paint is easily damaged during installation. Furthermore, in the context of online shopping, customer dissatisfaction and refunds are common. If returned unsatisfactory broom or mop handles have peeling paint, they are difficult to resell and need to be returned to the factory for repainting. Utility Model Content

DETAILED DESCRIPTION

[0026] The technical scheme in the utility model will be further explained in connection with the drawings and embodiments.

[0027] As Figures 1-3 The multi -section pole shown, including at least one A pole 100 and B pole 200, A pole 100 and B pole 200 are connected in turn alternately, and the multi -section pole of three -section structure is A pole 100, B pole 200 and A pole 100 in turn, and details are seen Figure 4 , and the multi -section pole of four -section structure is A pole 100, B pole 200, A pole 100 and B pole 200 in turn, and details are seen Figure 5A rod 100 and B rod 200 are connected with a rod-shaped connecting piece.

[0028] The rod-shaped connecting piece includes a locking sleeve 300 and a locking shaft 400, which are made of plastic material. The locking sleeve 300 and the locking shaft 400 are provided with elastic locking portions 410 at one end away from each other. The locking sleeve 300 is provided with a mounting hole 310 at the other end. The locking shaft 400 is mounted in the mounting hole 310. The elastic locking portion 410 of the locking shaft 400 and the mounting hole 310 are provided with a mounting gap 320.

[0029] One side of the A rod 100 and the B rod 200 connected to each other is a hollow structure 110. The elastic locking portion 410 of the locking sleeve 300 is tightly fixed in the hollow structure 110 of the A rod 100. The elastic locking portion 410 of the locking shaft 400 is tightly fixed in the hollow structure 110 of the B rod 200. The B rod 200 is clamped into the mounting gap 320 to form a multi-section rod structure.

[0030] As shown in Figures 1-3 , the bottom of the mounting hole 310 is provided with an internal thread 311. The other end of the locking shaft 400 is provided with an external thread 420. The internal thread 311 and the external thread 420 are engaged and connected to form the connecting structure of the locking sleeve 300 and the locking shaft 400, which is convenient for users to disassemble and assemble the multi-section rod.

[0031] As shown in Figures 1-3 , the elastic locking portion 410 includes a countersunk hole 411 and an elastic groove 412 arranged along the axis direction of the locking sleeve 300 or the locking shaft 400. The elastic groove 412 penetrates to the end face away from each other of the locking sleeve 300 and the locking shaft 400. The countersunk hole 411 penetrates the end faces of the locking sleeve 300 or the locking shaft 400. The threaded section of the countersunk hole 411 is arranged on the end away from each other of the locking sleeve 300 and the locking shaft 400. The elastic groove 412 is arranged at the threaded section of the countersunk hole 411. The locking screw 413 is arranged in the countersunk hole 411. Therefore, the assembly personnel can tighten the locking screw 413 during production to expand the countersunk hole 411. Because of the existence of the elastic groove 412, the elastic locking portion 410 is tightly outward, which achieves the purpose of fixing the locking sleeve 300 in the hollow structure 110 of the A rod 100 and fixing the locking shaft 400 in the hollow structure 110 of the B rod 200. At the same time, when the returned goods of online shopping are damaged, only the new locking sleeve 300 and the locking shaft 400 need to be replaced, without returning to the factory for repair.

[0032] Specific locking sleeve 300 and locking shaft 400 away from each other one end of the circumferential surface is provided with expansion protrusions 414, expansion protrusions 414 close to the inner side of the A rod 100 or B rod 200 cavity structure 110 fixed, so that the locking sleeve 300 and A rod 100 or locking shaft 400 and B rod 200 between the mutual displacement is not easy, that is, the connection is more firm and stable.

[0033] As shown in Figures 1-3 Locking sleeve 300 is provided with a convex edge 330 protruding in the circumferential direction at one end close to the mounting hole 310, and the end surface of the A rod 100 is on the convex edge 330, and the locking shaft 400 is provided with a convex step 430 close to the middle position, and the end surface of the B rod 200 is on the convex step 430, which plays the role of axial positioning of the fixed position of the elastic locking part 410.

[0034] A rod 100 and B rod 200 are both or either one of them is a tubular structure, and in the embodiment, A rod 100 and B rod 200 are both tubular structures, because the tubular structure helps to save materials, and the convex step 430 close to one side of the B rod 200 and the convex edge 330 close to one side of the A rod 100 are both provided with a groove 431, which plays a role of giving way to ensure that the A rod 100 and the convex edge 330 are close to each other, and the B rod 200 and the convex step 430 are close to each other.

[0035] As shown in Figure 1 B rod 200 is provided with a reduced diameter section 210 at one end, which is clamped into the mounting gap 320, and the reduced diameter section 210 is provided with a transition section 220 away from the A rod 100 side, which can be a circular arc transition or an inclined transition, and the transition section 220 is on the end surface close to the mounting hole 310, so that the outer diameter of the B rod 200 is the same as that of the A rod 100.

[0036] As shown in Figure 4 The cleaning tool comprises a cleaning head 500 connected with a plurality of rods, wherein the cleaning head 500 is in the structure of a mop head, a broom head or a cloth head.

[0037] As shown in Figure 5 The cleaning tool comprises a waste temporary storage container 600 connected with a plurality of rods, wherein the waste temporary storage container 600 can be used for storing garbage or waste water, and is in the structure of a dustpan.
