Description

Technical Field

[0001] The present application relates to the technical field of fishing gear, and more specifically, to a quick-detachable scoop net adapter. Background Art

[0002] A scoop net is a commonly used auxiliary tool for fishing. It is used to scoop the caught fish out of the water with a fishing rod. It is usually composed of a net rod and a net. With the development of fishing gear technology, foldable and detachable scoop nets have been developed to facilitate anglers to carry scoop nets. The scoop net adapter is the core component of the detachable scoop net. The technical solutions for the scoop net adapter in the prior art are:

[0003] (1) The Chinese utility model patent with publication number CN 207485818 U, a scoop net anti-rotation connector, discloses a net joint composed of an upper cap and a connecting piece, with the upper top piece serving as a net rod joint, and the net joint and the net rod joint cooperate through an L-shaped notch and a spring provided by the connecting piece to achieve a fixed connection and anti-rotation effect between the net and the net rod. However, this solution has the problem that the scoop net is easily disassembled by mistake when it is subjected to axial pressure.

[0004] (2) A Chinese utility model patent with publication number CN 206413617 U, a fishing gear scoop net ring and handle quick anti-rotation connector, discloses a net joint with an annular steel ball groove and a latch groove, a net rod joint with a retaining spring to fix the steel ball, the net joint and the net rod joint are fixed by the steel ball, and the net joint is inserted into the latch groove by the latch to achieve the fixed connection and anti-rotation effect of the net and the net rod. However, this solution has the problem that the scoop net is easily disassembled by mistake when it is subjected to axial tension.

[0005] Based on the above technical solutions, we can see that although the scoop net adapter in the prior art achieves the effects of quick release and anti-rotation, its connection mechanism will be subjected to force during the use of the scoop net, and there is a risk of failure of the connection between the net and the net pole. Utility Model Content

[0006] To solve the problems existing in the existing scoop nets, the technical solution adopted in this application is a quick-detachable scoop net adapter, including a net tool adapter and a net rod adapter;

[0007] The outer wall of the net joint is provided with a locking groove, the net rod joint is provided with a combining cavity for inserting the net joint, a bead hole is provided through the side wall of the combining cavity, a locking sleeve movably connected to the net rod joint through an elastic component is provided outside the bead hole, a reducing ring is provided inside the locking sleeve corresponding to the position of the bead hole, a locking bead is loaded in the bead hole, and the diameter of the locking bead is greater than the thickness of the side wall of the combining cavity, and the net joint and the net rod joint are respectively provided with matching upper positioning teeth and lower positioning teeth.

[0008] Preferably, the opening diameter of the bead hole in the inner wall of the binding cavity is smaller than the diameter of the locking bead.

[0009] Preferably, a limiting tongue is arranged inside the locking sleeve, and a limiting groove allowing the limiting tongue to move therein is arranged at a position of the net rod joint corresponding to the limiting tongue.

[0010] Preferably, the net joint comprises a connecting core, an anti-rotation sleeve is sheathed on the connecting core, and the anti-rotation sleeve is connected to the connecting core by threads.

[0011] Preferably, an angle fixing hole is provided through the side wall of the anti-rotation sleeve, and an angle fixing nail is screwed into the angle fixing hole.

[0012] Preferably, the upper positioning teeth and the lower positioning teeth are configured as mutually meshing trapezoidal teeth with a taper of 1°.

[0013] Preferably, the elastic component is a spring coiled around the net rod joint, and both ends of the spring are fixedly connected to the locking sleeve and the net rod joint respectively.

[0014] Preferably, the net rod joint comprises a net rod connecting piece and an adapter, the adapter is plugged into the net rod connecting piece, and at least one of the side walls that contact each other when the adapter and the net rod connecting piece are plugged into each other is a plane.

[0015] Preferably, the outer wall of the locking sleeve is provided with anti-slip grooves.

[0016] The beneficial effects of the utility model are:

[0017] 1. When in use, any force in any direction between the scoop net and the net rod will not directly affect the quick disassembly and assembly mechanism composed of the locking groove, bead hole, locking sleeve, locking bead and elastic component. When the net and the net rod are subjected to axial tension in opposite directions, the locking bead is subjected to force in the direction of the locking sleeve and transmits pressure perpendicular to the axial direction of the scoop net to the locking sleeve. This pressure will not cause the locking sleeve to rotate. Therefore, there is no risk of failure of the connection between the net rod and the net during use.

[0018] 2. During the disassembly and assembly of the scoop net and the net pole, it is only necessary to rotate the locking sleeve and point the end of the locking sleeve reducing ring with a relatively larger inner diameter toward the locking bead, so that the locking bead gains the freedom to move in the direction of the locking sleeve. At this time, the net can be drawn out or plugged in at will. When the net and the net pole need to be locked, it is only necessary to loosen the locking sleeve, and the locking sleeve will automatically rotate under the drive of the elastic component, and the end of the reducing ring with a relatively smaller inner diameter will point toward the locking bead, and the locking bead will be pushed into the locking groove from the bead hole, thereby completing the rapid locking of the net and the net pole.

[0019] 3. The joints of the net and the pole are provided with mutually cooperating positioning teeth, and the anti-rotation function between the net and the pole can be realized without the use of additional anti-rotation accessories.

[0020] 4. The design of the internal limiting tongue of the locking sleeve and the external limiting groove of the net rod joint can prevent the narrow section of the reducing ring from re-contacting the locking bead due to excessive rotation angle during use, making it impossible to disassemble.

DETAILED DESCRIPTION

[0035] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0036] It should be noted that the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0037] A quick-release scoop net adapter provided in an embodiment of the present application is now described:

[0038] Example 1

[0039] like Figure 1 , 2 As shown in Figures 3, 7, 8 and 9, a quick-release scoop net adapter includes a net joint 1 and a net rod joint 2. In this embodiment, the net joint 1 is provided with an internal thread, and the net rod joint 2 is provided with an external thread, which are respectively used to connect with the net and the net rod of the scoop net.

[0040] The outer wall of the net joint 1 is provided with a locking groove 10, the net rod joint 2 is provided with a combination cavity 23 for inserting the net joint 1, a bead hole 11 is provided through the side wall of the combination cavity 23, a locking sleeve 5 movably connected to the net rod joint 2 through an elastic component is provided outside the bead hole 11, a reducing ring 14 is provided inside the locking sleeve 5 corresponding to the position of the bead hole 11, a locking bead 7 is loaded in the bead hole 11, and the diameter of the locking bead 7 is greater than the thickness of the combination cavity 23, and the net joint 1 and the net rod joint 2 are respectively provided with matching upper positioning teeth 13 and lower positioning teeth 12.

[0041] Before use, the net tool joint 1 and the net rod joint 2 are first connected to the net tool and the net rod respectively. At this time, the locking sleeve 5 is acted upon by the elastic component, and the narrow section of the reducing ring 14 in the locking sleeve 5 is aligned with the position of the locking bead 7, and the locking bead 7 is pushed into the bead hole 11, and the locking bead 7 passes through the bead hole 11 to be exposed inside the combination cavity 23. When plugging is required, the locking sleeve 5 is manually rotated to change the state from the narrow section of the reducing ring 14 inner diameter aligning with the locking bead 7 to the wide section aligning with the locking bead 7, so as to provide a space for the locking bead 7 to move toward the locking sleeve 5 in the bead hole 11. At this time, the net tool joint 1 is inserted into the net rod joint 2. When the bottom of the net tool joint 1 passes through the bead hole 11, the locking sleeve 5 can be released, and the net tool joint 1 is continuously inserted into the net rod joint 2 until the locking groove 10 reaches the position of the locking bead 7. Under the action of the elastic component, the reducing ring 14 of the locking sleeve rotates to push the locking bead 7, and the locking bead 7 is pushed into the locking groove 10, and the narrowest position of the reducing ring 14 is aligned with the locking bead 7. At this time, there will be an obvious sense of segmentation in the touch, and a corresponding sound can be heard, which means that the connection between the net joint 1 and the net rod joint 2 is completed.

[0042] During use, any pulling, bending, etc. of the net tool joint 1 and the net rod joint 2 will not directly affect the locking sleeve 5, the locking bead 7, the elastic component, the bead hole 11 and the locking groove 10, and the net tool joint 1 and the net rod joint 2 are firmly connected. This is because when the net tool and the net rod are subjected to axial tension in opposite directions, the locking bead 7 is subjected to force in the direction of the locking sleeve 5 and transmits to the locking sleeve 5 a pressure perpendicular to the axial direction of the scoop net. The pressure will not cause the locking sleeve 5 to rotate, so there is no risk of failure of the connection between the net rod and the net tool during use.

[0043] During the disassembly process, the locking sleeve 5 is rotated to change the state where the narrow section of the reducing ring 14 is aligned with the locking bead 7 to the state where the wide section is aligned with the locking bead 7. At this time, the locking bead 7 regains the freedom to move toward the locking sleeve 5, and the net joint 1 can be pulled out to complete the disassembly.

[0044] Furthermore, if Figure 3 and Fig. 9 As shown, the opening diameter of the bead hole 11 on the inner wall of the combination cavity 23 is smaller than the diameter of the locking bead 7. In order to make the quick-release scoop net adapter provided by the present application work more stably and reliably, the opening diameter of the bead hole 11 on the inner wall of the combination cavity 23 is designed to be smaller than the diameter of the locking bead 7, so as to prevent the locking bead 7 from leaking out of the bead hole 11 when the net joint 1 is not locked.

[0045] Furthermore, if Figure 2 , 3As shown in , 4, and 8, a limiting tongue 16 is provided inside the locking sleeve 5, and a limiting groove 15 is provided at the position of the net rod joint 2 corresponding to the limiting tongue 16, in which the limiting tongue 16 is allowed to move. In the present application, the reducing ring 14 is provided as a combination of three groups of wide sections and narrow sections. Since it includes a plurality of reducing diameter combinations, it is possible that the narrow section is over-twisted during use so that it is realigned with the bead hole 11. Therefore, by providing the limiting tongue 16 and the limiting groove 15, the rotation angle of the user's rotation of the locking sleeve 5 will not exceed one reducing diameter combination, preventing the situation that the locking sleeve 5 is rotated but the net rod joint 2 and the net gear joint 1 are still not unlocked, making the quick-release scoop net adapter provided by the present application easier to use, and there is no need to pay attention to whether the locking sleeve 5 is rotated in place during use.

[0046] Furthermore, if Figure 1 , 2 As shown in FIGS. 3, 11 and 12, the net joint 1 comprises a connecting core 3, and an anti-rotation sleeve 4 is sheathed on the connecting core 3. The anti-rotation sleeve 4 is connected to the connecting core 3 by threads. The upper positioning teeth 13 are arranged on the anti-rotation sleeve 4. Figure 2 Under the design of the locking groove 10 provided in the invention, the net joint 1 can be manufactured by the connecting core 3 and the anti-rotation sleeve 4 in one piece. Fig.12 Under the provided locking groove 10 design, since the position of the locking groove 10 corresponds to the bead hole 11, the upper positioning teeth 13 and the lower positioning teeth 12 also need to correspond in position to achieve the engagement of the upper and lower positioning teeth, which increases the difficulty of manufacturing. In order to reduce the requirements for manufacturing accuracy, the present application proposes that the connecting core 3 and the anti-rotation sleeve 4 are manufactured separately. When in use, the anti-rotation sleeve 4 is connected to the connecting core 3 by threads and rotated to a suitable position so that the upper positioning teeth 13 and the lower positioning teeth 12, the locking groove 10 and the bead hole 11 correspond to each other at the same time.

[0047] Fig.12 The provided positioning groove 10 design can prevent the net joint 1 and the net rod joint 2 from rotating not only through the cooperation of the upper positioning teeth 13 and the lower positioning teeth 12, but also through the cooperation of the locking groove 10 and the locking bead 7, thereby further improving the connection stability of the net joint 1 and the net rod joint 2.

[0048] Furthermore, if Figure 1 , 2As shown in , 3 and 11, an angle fixing hole 22 is provided through the side wall of the anti-rotation sleeve 4, and an angle fixing nail 9 is screwed into the angle fixing hole 22. Since the anti-rotation sleeve 4 and the connecting core 3 are not made in one piece, in order to prevent the anti-rotation sleeve 4 and the connecting core 3 from rotating relative to each other during use, the present application provides a design of the angle fixing nail 9. When the anti-rotation sleeve 4 is rotated to a suitable position so that the upper positioning teeth 13 and the lower positioning teeth 12, the locking groove 10 and the bead hole 11 correspond to each other at the same time, the angle positioning nail 9 is screwed into the angle fixing hole 22 and pressed on the external thread of the connecting core 3 to fix the relative position of the anti-rotation sleeve 4 and the connecting core 3, thereby preventing the anti-rotation sleeve 4 and the connecting core 3 from rotating relative to each other.

[0049] Furthermore, if Figure 2 , 3 As shown, the upper positioning teeth 13 and the lower positioning teeth 12 are mutually meshing trapezoidal teeth with a taper of 1°. Figure 5 As shown, the shapes of the upper positioning teeth 13 and the lower positioning teeth 12 can be designed in a variety of ways, and the present application proposes a design scheme in which the upper positioning teeth 13 and the lower positioning teeth 12 are trapezoidal teeth with a taper of 1°, so that the upper positioning teeth 13 and the lower positioning teeth 12 can be firmly matched to prevent slight rotation, and at the same time, they are easy to splice and match, and the plug-in process is smooth.

[0050] Furthermore, if Figure 3 , 6 As shown in FIGS. 7, 8 and 9, the elastic component is a spring 6 wound around the net rod joint 2, and the two ends of the spring 6 are respectively fixedly connected to the locking sleeve 5 and the net rod joint 2. One end of the spring 6 is fixed to the lower fixing hole 17 set in the net rod connecting piece 25, and the other end is fixed to the upper fixing hole 18 set in the locking sleeve 5. At this time, the spring 6 is located between the locking sleeve 5 and the net rod connecting piece 25, and is completely wrapped by the locking sleeve 5, so that the locking sleeve 5 plays a role in protecting the elastic component.

[0051] Furthermore, if Figure 3 , 4 As shown in FIGS. 6 and 9, the net rod joint 2 includes a net rod connector 25 and an adapter 24. The adapter 24 is plugged into the net rod connector 25. When the adapter 24 and the net rod connector 25 are plugged in, at least one of the side walls that contact each other is a plane. In order to facilitate the inspection of the spring 6, the locking bead 7 and other components, the present application proposes a split design, so that the net rod joint 2 is composed of the net rod connector 25 and the adapter 24. At the same time, in order to prevent the adapter 24 and the net rod connector 25 from rotating relative to each other, the design makes the adapter 24 and the net rod connector 25 have at least one side wall that contacts each other when plugged in to be a plane. In this embodiment, the adapter 24 is inserted into the connecting groove 20 of the net rod connector 25 through the connecting tongue 21. The shapes of the connecting tongue 21 and the connecting groove 20 are both rounded rectangles. The adapter fixing nail 8 passes through the adapter 24 and is screwed into the net rod connector 25, so that the adapter 24 and the net rod connector 25 are completely fixed.

[0052] When the spring 6 and the locking bead 7 need to be replaced, the adapter 24 can be pulled out from the net rod connecting piece 25 by removing the adapter fixing nail 8, which provides convenience for maintenance and prolongs the service life of the equipment.

[0053] Furthermore, if Figure 2 , 3 As shown in Figure 5, the outer wall of the locking sleeve 5 is provided with anti-skid patterns 19. When the scoop net is used, there are many scenes where it comes into contact with water. The anti-skid patterns 19 on the outer wall of the locking sleeve 5 can easily disassemble the net rod joint 2 and the net joint 1 when the outer wall of the scoop net adapter is wet.

[0054] The embodiments described above are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, a person skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. Such modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present application, and should all be included in the protection scope of the present application.
