Description

Technical Field

[0001] The utility model relates to the technical field of fishing gear accessories, in particular to an umbrella stick connecting piece. Background Art

[0002] The umbrella pole connector is a fishing gear accessory for fixing a fishing umbrella. It can be installed in a fishing box or a fishing platform for use. After fixing the fishing umbrella, the direction of the fishing umbrella can also be adjusted. The existing umbrella pole connector structure can refer to a fishing umbrella steering structure disclosed in a Chinese patent with a publication number of CN220343826U. The structure includes a mounting shell, a pressing rod is rotatably penetrated in the mounting shell, and a clamping body for clamping the umbrella is fixedly provided at one end of the pressing rod. An external gear is fixedly provided on the pressing rod, and an internal gear is provided in the mounting shell. When the pressing rod is axially inserted into the mounting shell, the external gear and the internal gear are plugged and meshed to limit the rotation of the pressing rod. An adjustment mechanism is also provided between the pressing rod and the mounting shell, which can drive the external gear and the internal gear to approach each other for plug-in meshing or move away from each other to disengage.

[0003] According to the above structure, it can be known that when the pressing rod moves axially to disengage the inner and outer gears, the direction of the fishing umbrella can be adjusted by rotation. When the pressing rod moves axially to the point where the inner and outer gears are plugged and meshed, the limit pressing rod rotates. There are generally two ways to manufacture the outer gear and the inner gear. One is to process them as separately processed components and then assemble them. Generally, the inner ring wall of the outer gear is inserted on the pressing rod with an interference fit, and the outer ring wall of the inner gear is inserted on the inner wall of the mounting shell with an interference fit. However, after the fishing umbrella is installed on the clamp body, the meshing part between the two gears needs to withstand all the torque generated by the fishing umbrella under the influence of gravity and leverage. The torque acts on the limit component for a long time, causing wear between the outer ring wall and the mounting shell until it becomes loose, resulting in the limit component. The torque that can be tolerated is weakened until slipping occurs and the position cannot be limited; another way is to integrate the outer gear, the pressing rod and the inner gear with the mounting shell. Although this can effectively reduce the deflection of the limiting component, the one-piece molding process will increase the difficulty of demolding the mold, and the inner and outer gears need to be precisely plugged in and meshed. After molding with the mold, the meshing parts still need to be fine-machined, which makes production difficult and increases production costs. Therefore, if the limiting component on the existing umbrella stick connecting piece is manufactured separately, it is difficult to overcome the defect that the limiting component is worn due to long-term torque until the fit becomes loose and slipping occurs. If integrated molding is used, it is difficult to overcome the defect of high production difficulty. Therefore, there is still room for improvement in the existing umbrella stick connecting piece. Utility Model Content

[0004] The existing limiting components on the umbrella pole connecting piece are produced separately, but there is a disadvantage that the limiting components wear and slip due to the torque they bear for a long time. Although the one-piece molding setting can solve the defect of the limiting component wear, it will increase the production difficulty and production cost. The purpose of the utility model is to provide an umbrella pole connecting piece whose limiting components can be produced separately and can overcome the wear caused by the torque.

[0005] In order to solve the above technical problems, the utility model is solved by the following technical solutions:

[0006] A connecting piece for an umbrella stick comprises a mounting shell and a rotating body inserted in the mounting shell, a clamping body is arranged at one end of the rotating body, a limiting mechanism is arranged between the rotating body and the mounting shell for limiting the position when they cooperate with each other or releasing the limit of the self-rotation of the rotating body when they disengage from each other, an adjusting mechanism is arranged between the rotating body and the mounting shell for driving the limiting mechanism to cooperate with each other or disengage from each other, the limiting mechanism comprises a pair of adjusting limiting members respectively fixed on the mounting shell and the rotating body, and a circumferential positioning component is arranged on the adjusting limiting member for preventing the adjusting limiting member from rotating circumferentially around the rotating body.

[0007] By adopting the above scheme, compared with the prior art, the adjustment limit piece in this scheme uses the circumferential positioning component to reduce the possibility of circumferential deflection of the limit adjustment piece when it is subjected to torque, thereby optimizing the supporting performance of the umbrella pole connecting piece and reducing the possibility of circumferential deflection of the rotating body due to force; and the adjustment limit piece does not need to be produced and reprocessed together with the rotating body and the mounting shell, but can be produced as a separate component, which simplifies the shape of the rotating body and the mounting shell and reduces the difficulty of mold design. Moreover, in subsequent processing, the tolerance range of the parts can be increased, and an optional method is adopted during assembly to reduce the requirements for processing accuracy when each component is matched, which can effectively reduce the processing difficulty and achieve the purpose of reducing costs.

[0008] Preferably, the adjustment limit member is an engagement assembly, which includes a pair of mounting rings coaxially arranged with the rotating body and respectively fixed to the rotating body and the mounting shell, one of the mounting rings being provided with a convex outer engagement toothed disc, and the other mounting ring being provided with a concave inner engagement toothed disc for the outer engagement toothed disc to be inserted and engaged with when the mounting rings are close to each other, so that when the rotating body moves axially, one of the mounting rings is driven to approach or move away from the other mounting ring.

[0009] Preferably, the rotating body includes a connecting part connected to the clamp body and a rotating shaft arranged on the connecting part, the mounting shell is sleeved on the rotating shaft, and the circumferential positioning assembly includes a limit column fixedly arranged on the two end surfaces opposite to each other of the two mounting rings, and the connecting part and the mounting shell are both provided with limit holes for the limit column to be inserted for circumferential limiting.

[0010] By adopting the above scheme, the limit column and the limit hole in this scheme play the role of bearing torque, and the limit column inserted in the limit hole can prevent the mounting ring from being deflected by force. The purpose of fixing the mounting ring on the rotating body and the mounting shell is to prevent the mounting ring from detaching. The limit component in the prior art utilizes the friction force generated by the interference between its side wall and the mounting shell and the rotating body. Therefore, compared with the prior art, the adjustment limit member in this scheme will not be deflected due to bearing torque.

[0011] Preferably, the limiting column and the limiting hole are interference fit.

[0012] By adopting the above scheme, after the limiting column and the limiting hole in the scheme are installed in coordination, they simultaneously play the role of a circumferential positioning mounting ring and a fixed mounting ring, simplifying the structure of the adjusting limiting member and making production more convenient.

[0013] Preferably, a plurality of groups of limiting posts and limiting holes are arranged on the mounting ring at intervals along the circumference of the mounting ring.

[0014] By adopting the above solution, providing multiple groups of limiting columns and limiting holes can enhance the effect of the circumferential positioning installation ring.

[0015] Preferably, the adjusting mechanism includes an adjusting piece arranged at one end of the rotating shaft away from the connecting part, the adjusting piece is provided with a threaded hole, and the rotating shaft is provided with a threaded section matching the threaded hole. The adjusting piece can utilize threaded transmission to leave a gap between the connecting part and the mounting shell for axial movement of the rotating shaft, or to approach the connecting part and abut against the mounting shell to limit the position.

[0016] By adopting the above scheme, the rotating body can be locked or unlocked to move axially by twisting the adjusting piece. After unlocking, the rotating body can be driven to move by pushing the adjusting piece in the direction of the clamp body, and the rotating body drives one mounting ring away from the other mounting ring. At this time, the rotating body can rotate to adjust the angle of the clamp body; after adjustment, the adjusting piece is pulled in the opposite direction to drive the rotating body to move in the opposite direction, driving the mounting ring close to the other mounting ring. At this time, the inner interlocking gear disc and the outer interlocking gear disc are plugged into and interlock with each other, thereby limiting the rotation of the rotating body.

[0017] Preferably, the clamp body comprises a first clamp block integrally extending from the connecting portion, a second clamp block movably disposed on the first clamp block, and a cam handle assembly for driving the second clamp block to approach or move away from the first clamp block.

[0018] By adopting the above solution, umbrellas with different diameters can be placed between the second clamping block and the first clamping block. After the umbrella is placed, the cam handle assembly is pulled to quickly clamp the umbrella.

[0019] The utility model has significant technical effects due to the adoption of the above technical scheme: compared with the prior art, the adjusting limit piece in the scheme reduces the possibility of circumferential deflection of the limit adjusting piece when subjected to torque by means of a circumferential positioning component, optimizes the supporting performance of the umbrella pole connecting piece, and reduces the possibility of circumferential deflection of the rotating body when subjected to force; and the adjusting limit piece does not need to be produced and reprocessed together with the rotating body and the mounting shell, and can be produced as a separate component, which simplifies the shapes of the rotating body and the mounting shell and reduces the difficulty of mold design. Moreover, in subsequent processing, the tolerance range of the parts can be increased, and an optional matching method is adopted during assembly to reduce the requirements for processing accuracy when each component is matched, which can effectively reduce the processing difficulty and achieve the purpose of reducing costs.

[0029] The utility model is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0030] Example

[0031] An umbrella stick connecting piece, according to Figures 1 to 3 As shown, it includes a mounting shell 1 and a rotating body 2 inserted into the mounting shell 1, one end of the rotating body 2 is provided with a clamping body, the clamping body includes a first clamping block 8 integrally extended on the rotating body 2, and a second clamping block 9 is movably provided on the first clamping block 8. In this embodiment, one end of the second clamping block 9 is pivotally connected to the first clamping block 8, and the other end of the second clamping block 9 is provided with a cam handle assembly 10. The second clamping block 9 can be driven close to or away from the first clamping block 8 by pulling the cam handle assembly 10.

[0032] A limiting mechanism is provided between the rotating body 2 and the mounting shell 1 to limit the rotation of the rotating body 2 when they cooperate with each other or to release the limit of the rotation of the rotating body 2 when they are separated from each other. An adjusting mechanism is also provided to drive the limiting mechanism to cooperate with or separate from each other. Figures 2 to 5 As shown, in this embodiment, the rotating body 2 includes a connecting portion 21 integrally provided with the first clamping block 8, a rotating shaft 22 is screwed on the connecting portion 21, the mounting shell 1 is sleeved on the rotating shaft 22, and the limiting mechanism includes a pair of mounting rings 3 coaxially arranged with the rotating body 2, one of the mounting rings 3 is convexly provided with an outer engaging toothed disc 31, and the other mounting ring 3 is concavely provided with an inner engaging toothed disc 32. When the rotating body 2 moves axially, one of the mounting rings 3 is driven to approach or move away from the other mounting ring 3. At this time, the inner engaging toothed disc 32 and the outer engaging toothed disc 31 are plugged into each other and engage in limiting. The mounting ring 3 is also provided with a circumferential positioning component that can prevent the mounting ring 3 from circumferentially deflecting around the rotating shaft 22. Figure 3 As shown in or 5, in this embodiment, the circumferential positioning assembly includes limit columns 4 fixedly arranged on the two end surfaces opposite to each other of the two mounting rings 3, and limit holes 5 for the limit columns 4 to be inserted for circumferential limiting are provided on the connecting portion 21 and the mounting shell 1. In this embodiment, the limit columns 4 and the limit holes 5 are arranged in a plurality of groups at intervals around the circumference on the mounting ring 3, and an interference fit relationship is adopted between the limit columns 4 and the limit holes 5.

[0033] according to Figure 2 , 4 As shown in Figures 7 and 8, the adjusting mechanism includes an adjusting member 6 arranged at one end of the rotating shaft 22 away from the clamping body, the adjusting member 6 is provided with a threaded hole 61, and the rotating body 2 is provided with a threaded section 7 that cooperates with the threaded hole 61. The adjusting member 6 can utilize threaded transmission to move away from the mounting shell 1 and leave a gap between the mounting shell 1 for the axial movement of the rotating body 2, or approach the mounting shell 1 and abut against the mounting shell 1 to limit the position.

[0034] Combined with the above structure, reference Figures 1 to 8 It can be seen that the angle adjustment method of the umbrella pole connecting piece in this embodiment is as follows:

[0035] First, loosen the adjusting member 6 to leave a gap between it and the mounting shell 1 for the axial movement of the rotating shaft 22, and then push the adjusting member 6 to make the rotating shaft 22 drive one mounting ring 3 away from the other mounting ring 3.

[0036] The adjustment limit member in this embodiment uses the circumferential positioning assembly to reduce the possibility of circumferential deflection of the limit adjustment member 6 when subjected to torque, optimizes the support performance of the umbrella pole connecting member, and reduces the possibility of circumferential deflection of the rotating body 2 when subjected to force;

[0037] Moreover, the adjustment limit piece does not need to be produced and processed together with the rotating body 2 and the mounting shell 1, but can be produced as a separate component, which simplifies the shape of the rotating body 2 and the mounting shell 1 and reduces the difficulty of mold design. In subsequent processing, the tolerance range of the parts can be increased, and an optional method can be used during assembly to reduce the requirements for processing accuracy when the components are matched, which can effectively reduce the processing difficulty and achieve the purpose of reducing costs.
