Description

Technical Field

[0001] The utility model relates to the technical field of lockable net connecting heads, in particular to a net connecting head with a lockable opening / closing rotation angle. Background Art

[0002] Generally, a net is composed of a net rod and a net head. A net is an essential fishing tool for fishing fish ashore. When fishing for a large fish (more than 1 kg), it is very difficult to lift it ashore with an ordinary hook line. Hard pulling often breaks the rod, breaks the line or makes the fish escape the hook. Therefore, a net must be used to catch the fish;

[0003] At present, most of the nets on the market are either integral or foldable. At the same time, there are also some nets installed by a threaded screwing connection method. This connection structure of the net pays more attention to the structural materials, especially at the connection between the rod and the frame. If the threaded screwing connection is too strong due to the user's strength, the phenomenon of slipping threads will occur between the rod and the frame, resulting in the loosening of the net connection and making it unusable.

[0004] Therefore, we propose a net connecting head with a lockable opening / closing rotation angle. Content of the Utility Model

[0005] The purpose of the utility model is to solve the defects existing in the prior art, and to propose a net connecting head with a lockable opening / closing rotation angle.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0007] A net connecting head with a lockable opening / closing rotation angle includes a fixed rod, and an extension rod arranged at one end of the fixed rod. One end of the extension rod far away from the fixed rod is threadedly screwed with a connecting rod. A torsion spring is fixedly arranged inside the connecting rod, and the torsion spring is used for locking and connecting rotation. The fixed rod and the extension rod are detachably connected.

[0008] As a further scheme of the utility model: a threaded connection hole for threadedly screwing with the extension rod is opened at one end of the fixed rod close to the extension rod.

[0009] As a further scheme of the utility model: a first external thread is fixedly arranged at one end of the extension rod close to the fixed rod. The extension rod is threadedly screwed with the threaded connection hole through the first external thread. A second external thread is arranged at one end of the extension rod far away from the first external thread.

[0010] As a further scheme of the utility model: the extension rod is threadedly screwed with the connecting rod through the second external thread. A clamping groove is opened at one end of the extension rod close to the connecting rod.

[0011] As a further solution of the utility model: the clamping groove is an oblique hole, and the clamping groove is used for plugging with the torsion spring.

[0012] As a further solution of the utility model: a rubber handle is fixedly provided on one end of the fixing rod away from the extension rod, and at least two fixing slots are fixedly provided on the upper half of the fixing rod.

[0013] As a further solution of the utility model: a sliding groove is provided inside the fixed slot, the sliding groove penetrates the fixed slot and extends into the fixed rod, a sliding connection block is slidably connected inside the fixed slot for limiting the rotation of the extension rod, a telescopic block is slidably connected inside the sliding connection block via a reset spring, and at least two plug-in slots are provided on the fixed slot for connecting with the telescopic block.

[0014] Compared with the prior art, the utility model provides a scoop net connector capable of locking the opening and closing rotation angle, which has the following beneficial effects:

[0015] The utility model, the torsion spring arranged inside the connecting rod can make the extension rod lock the connection rotation when being threadedly connected with the connecting rod, so as to avoid the connection between the extension rod and the connecting rod from being loosened when the user uses the scoop net, causing the connecting rod to fall and fail to salvage the fish in time, and at the same time, the traditional threaded connection method will cause the thread slipping phenomenon when over-twisting, causing the connection between the two to be unable to be fixed. The utility model, by arranging the extension rod at one end of the fixed rod, can increase the length of the fixed rod, and can also replace the extension rods of different lengths to further increase the overall length of the fixed rod, and at the same time, the fixed rod and the extension rod are detachably connected, which can facilitate the user to disassemble and replace the extension rod, and the end of the extension rod away from the fixed rod is threadedly connected with the connecting rod, which can enable the user to assemble the scoop net to salvage the fish, and the devices connected to the fixed rod are all detachable, which can not only facilitate the user to store the device as a whole, but also facilitate the user to disassemble and replace the damaged part.

[0024] Embodiment

[0025] A netting connector capable of locking and opening / closing the rotation angle, as Figures 1-4As shown, it includes a fixed rod 1 and an extension rod 4 provided at one end of the fixed rod 1. A connecting rod 7 is screwed to the end of the extension rod 4 away from the fixed rod 1. A torsion spring 11 is fixedly arranged inside the connecting rod 7, and the torsion spring 11 is used for locking and connecting rotation. The fixed rod 1 and the extension rod 4 are detachably connected. By providing the extension rod 4 at one end of the fixed rod 1, the length of the fixed rod 1 can be increased. At the same time, extension rods 4 of different lengths can be replaced to further increase the overall length of the fixed rod 1. And since the fixed rod 1 and the extension rod 4 are detachably connected, it is convenient for the user to disassemble and replace the extension rod 4. The end of the extension rod 4 away from the fixed rod 1 is screwed to the connecting rod 7, enabling the user to assemble the fishing net to catch fish. All the devices connected to the fixed rod 1 are detachable, which not only facilitates the user to store the whole device but also allows the user to disassemble and replace the damaged parts, avoiding the need to replace the whole when only a single part is damaged. At the same time, the torsion spring 11 arranged inside the connecting rod 7 can lock the connection rotation when the extension rod 4 is screwed to the connecting rod 7, preventing the connection between the extension rod 4 and the connecting rod 7 from loosening when the user uses the fishing net, resulting in the dropping of the connecting rod 7 and the inability to catch fish in time. At the same time, the traditional threaded connection method will have a thread slipping phenomenon when over-tightened, resulting in the inability to fix the connection between the two.

[0026] As Figures 1-4 shown, a threaded connection hole 2 for screwing with the extension rod 4 is provided at the end of the fixed rod 1 close to the extension rod 4. A first external thread 3 is fixedly arranged at the end of the extension rod 4 close to the fixed rod 1. The extension rod 4 is screwed to the threaded connection hole 2 through the first external thread 3. A second external thread 5 is provided at the end of the extension rod 4 away from the first external thread 3. By providing the threaded connection hole 2 at one end of the fixed rod 1, the extension rod 4 can be screwed to the fixed rod 1 through the first external thread 3 provided at its end, so that the extension rod 4 can be connected to the fixed rod 1, facilitating the user to disassemble and replace the extension rod 4 and the fixed rod 1.

[0027] As Figures 1-4As shown, the extension rod 4 is threadedly engaged with the connecting rod 7 through the second external thread 5. One end of the extension rod 4 close to the connecting rod 7 is provided with a clamping groove 6. The clamping groove 6 is an inclined hole and is used for inserting the torsion spring 11. By providing the second external thread 5 at the other end of the extension rod 4, the extension rod 4 can be threadedly engaged with the connecting rod 7 through the second external thread 5. At the same time, the clamping groove 6 opened at the top of the extension rod 4 enables the user to thread-connect the extension rod 4 and the connecting rod 7 to a certain extent, and then the lower end of the torsion spring 11 contacts the upper surface of the extension rod 4 so that the lower end of the torsion spring 11 can be inserted into the interior of the clamping groove 6. Thus, the rotation between the extension rod 4 and the connecting rod 7 can be locked by the action of the torsion spring 11, avoiding separation and thread slipping during use and installation.

[0028] As Figures 1-4 shown, a rubber handle 8 is fixedly provided at one end of the fixed rod 1 away from the extension rod 4. At least two fixed clamping grooves 9 are fixedly provided in the upper half of the fixed rod 1. A sliding groove 13 is opened inside the fixed clamping groove 9. The sliding groove 13 penetrates the fixed clamping groove 9 and extends into the fixed rod 1. A sliding connection block 10 for limiting the rotation of the extension rod 4 is slidably connected inside the fixed clamping groove 9. An expansion block 12 is slidably connected inside the sliding connection block 10 through a return spring 15. At least two insertion grooves 14 for clamping connection with the expansion block 12 are opened on the fixed clamping groove 9. By providing the rubber handle 8 at one end of the fixed rod 1, it is convenient for the user to use the whole device. The fixed clamping groove 9 fixedly provided in the upper half of the fixed rod 1 can use the sliding connection block 10 slidably connected inside it to squeeze and limit the extension rod 4 threadedly engaged inside the threaded connection hole 2, avoiding the unstable threaded engagement between the fixed rod 1 and the extension rod 4 during use, which may cause the extension rod 4 to continue to extend or shorten. At the same time, the two insertion grooves 14 opened on the fixed clamping groove 9 enable the expansion block 12 to be adjusted in two gears. When the expansion block 12 at the upper end of the sliding connection block 10 slides into the insertion groove 14 close to the fixed rod 1, the sliding connection block 10 can extend into the fixed rod 1 to squeeze the extension rod 4, thereby being able to squeeze and limit the extension rod 4. When the expansion block 12 is in the outer insertion groove 14, the sliding connection block 10 will not extend into the fixed rod 1, so that the fixed rod 1 and the extension rod 4 can be threadedly rotated. At the same time, the expansion block 12 is connected to the sliding connection block 10 through the return spring 15 inside the sliding connection block 10, enabling the expansion block 12 to have elasticity and facilitating the user to press the expansion block 12 for use.

[0029] Working principle: By setting the extension rod 4 at one end of the fixed rod 1, the length of the fixed rod 1 can be increased. At the same time, extension rods 4 of different lengths can be replaced to further increase the overall length of the fixed rod 1. The fixed rod 1 and the extension rod 4 are detachably connected, which facilitates the user to disassemble and replace the extension rod 4. One end of the extension rod 4 away from the fixed rod 1 is threadedly engaged with the connecting rod 7, enabling the user to assemble the fishing net to catch fish. All the devices connected to the fixed rod 1 are detachable, which not only facilitates the user to store the whole device but also enables the user to disassemble and replace the damaged parts, avoiding the need to replace the whole when only a single part is damaged. At the same time, the torsion spring 11 provided inside the connecting rod 7 can lock the connection rotation when the extension rod 4 is threadedly engaged with the connecting rod 7, preventing the connection between the extension rod 4 and the connecting rod 7 from loosening when the user uses the fishing net, resulting in the dropping of the connecting rod 7 and the inability to catch fish in time. At the same time, the traditional threaded connection method will experience thread slipping when over-tightened, resulting in the inability to fix the connection between the two.
