Technical Field
[0001] This utility model relates to the field of fishing gear technology, and in particular to a fishing float with a replaceable tail light. Background Technology
[0002] Fishing is a popular sport and recreational activity. At night, the cool weather and active fish make it an ideal time for many fishing enthusiasts. In this context, electronic fishing floats play a crucial role as an important electronic tool. The fishing float is an important tool for transmitting information about fish biting the hook. By observing the movement of the fishing float, anglers can not only judge the fish's feeding situation and decide when to lift the rod, but also identify the species of fish that has taken the bait based on the movement of the fishing float.
[0003] Currently, there are some problems with the structural design of commonly available fishing floats that urgently need to be solved. On the one hand, most fishing floats use an integrated tail light design. When the tail light is damaged, anglers have to replace the entire float. However, in actual use, often only the tail light fails, while the other parts of the float can still be used normally. This method of replacing the whole float not only causes a great waste of resources, but also significantly increases the cost of use for anglers.
[0004] On the other hand, in the connection between the float and the fishing line, the existing technology mainly relies on the tightening method to achieve fixation. For experienced anglers, the tightening method may not be difficult, but for beginners, the lack of proficiency in the tightening method becomes a major problem. During the operation, beginners are prone to the fishing line and the float separating, which not only affects the efficiency of fishing, but also greatly reduces the fishing experience, and may even cause anglers to lose interest in fishing.
[0005] Therefore, our company has developed a fishing float that can solve the above problems, which is of great significance for improving the user experience of anglers, reducing usage costs, and reducing resource waste. Utility Model Content
[0006] The main purpose of this invention is to provide a fishing float with a replaceable tail light, which can effectively solve the problems in the background art.
[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0008] A fish float with a replaceable float light includes a middle shell, a float tail shell threaded to the top of the middle shell, a float tail seat threaded to the top of the float tail shell, a float tail extension seat fixedly connected to the inner wall of the float tail seat, a float foot seat threaded to the bottom of the middle shell, a float foot extension seat fixedly connected to the inner wall of the float foot seat, a lamp holder fixedly connected to the inner bottom wall of the middle shell, a button battery fixedly connected to the inner wall of the lamp holder, a light source fixedly connected to the top of the lamp holder, a cylindrical base fixedly connected to the inner bottom wall of the middle shell, a first magnet fixedly connected to the inner wall of the cylindrical base, a locking point fixedly connected to the outer surface of the cylindrical base, a second magnet fixedly connected to the inner top wall of the lamp holder, and a locking groove formed on the inner wall of the lamp holder.
[0009] In order to achieve the effect of assembling and fixing the middle shell and the float tail shell together, as a fish float with replaceable float tail light according to the present invention, the top of the inner wall of the middle shell is provided with a first internal thread, and the bottom of the float tail shell is provided with a first external thread.
[0010] In order to achieve the effect of assembling and fixing the float base and the middle shell, as well as the float tail shell and the float tail base together, as a fish float with replaceable float tail light of this utility model, the top of the inner wall of the float tail shell and the bottom of the inner wall of the middle shell are provided with a second internal thread, and the outer surface of the float tail base and the outer surface of the float base are provided with a second external thread.
[0011] In order to achieve the effect of assembling and fixing the float tail seat and float tail extension seat, as well as the float foot seat and float foot extension seat together, as a fish float with replaceable float tail light of this utility model, the float tail seat and float foot seat are provided with a slot at the opposite ends, the outer surface of the float tail extension seat and float foot extension seat are fixedly connected with a foot, and the outer surface of the float tail seat and float foot seat is provided with a compression groove.
[0012] In order to facilitate the entry of fishing line into the float, as a type of float with replaceable float tail light according to this utility model, a line through hole is opened at the center of the float tail seat, float foot seat, float tail extension seat and float foot extension seat.
[0013] To facilitate threading, as a fish float with replaceable float tail light according to this utility model, the inner bottom wall of the float tail seat and the inner top wall of the middle shell are both fixedly connected to an inner ring seat. The inner wall of the inner ring seat is provided with a third internal thread, and the bottom end of the float tail seat and the top end of the float foot seat are both provided with a third external thread. The outer surface of the inner ring seat is provided with a line hole.
[0014] Compared with the prior art, the present invention has the following beneficial effects:
[0015] 1. This is a replaceable float with a tail light. It consists of a lamp holder, button batteries, a light source, a cylindrical base, a first magnet, a locking point, a second magnet, and a locking slot. The light source is an LED. The lamp holder is fixed inside the middle shell using the magnetic attraction between the first and second magnets, as well as the locking point and locking slot. To fix it, align the opening of the locking slot with the locking point, and place the bottom of the lamp holder onto the cylindrical base, causing the first and second magnets to magnetically attract each other, completing the initial fixation. Then, rotate the lamp holder to engage the locking point with the end of the locking slot, completing the final fixation. The lamp holder contains four button batteries, and the light source is secured to the lamp holder with bolts. When replacing the float tail light, the float tail shell can be unscrewed from the middle shell to expose the light source. If only the light source needs to be replaced, the bolts can be removed to separate the light source from the lamp holder. A new light source can be installed and then bolted back onto the lamp holder. The same procedure applies when replacing the button battery. When replacing the entire lamp holder, rotate the lamp holder along the locking groove until the locking point is at the exit of the locking groove. Then, lift the lamp holder to separate the first and second magnet pieces, allowing the entire lamp holder to be removed. This way, when the tail light is damaged, anglers do not need to replace the entire float; only the damaged part of the tail light needs to be replaced, avoiding resource waste and reducing operating costs.
[0016] 2. This float with replaceable float tail light is designed with a middle shell, float tail shell, float tail seat, float tail extension seat, float foot seat, and float foot extension seat. When securing the fishing line to the float, the fishing line on the float foot first enters the through hole in the center of the float foot seat and the float foot extension seat. At the same time, insert the clip in the float foot extension seat into the clip groove of the float foot seat, assembling the float foot seat and the float foot extension seat together. After the fishing line passes through both, it enters the inner ring seat, passes through the line hole to the outside of the inner ring seat, passes through another line hole along the outside of the inner ring seat, and enters the inner ring seat again, ensuring that the length of the fishing line at that end exceeds the inner ring seat. At this point, screw the float foot seat in along the thread and tighten it to firmly secure the fishing line in the inner ring seat. The same method is used to secure the fishing line in the float tail seat. After securing them, fix both the float foot and the float tail to the middle shell, completing the fixation of the float and the fishing line. This avoids the need to use the method of tying the fishing line to fix the float and the fishing line, improving the fishing experience for novice users. Attached Figure Description

Detailed Implementation
[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] Example
[0027] like Figure 1-7 As shown, a fish float with a replaceable float tail light includes a middle shell 1, a float tail shell 2 threadedly connected to the top of the middle shell 1, a float tail seat 3 threadedly connected to the top of the float tail shell 2, a float tail extension seat 4 fixedly connected to the inner wall of the float tail seat 3, a float foot seat 5 threadedly connected to the bottom of the middle shell 1, a float foot extension seat 6 fixedly connected to the inner wall of the float foot seat 5, a lamp holder 7 fixedly connected to the inner bottom wall of the middle shell 1, a button battery 8 fixedly connected to the inner wall of the lamp holder 7, a light source 9 fixedly connected to the top of the lamp holder 7, a cylindrical seat 22 fixedly connected to the inner bottom wall of the middle shell 1, a first magnet 23 fixedly connected to the inner wall of the cylindrical seat 22, a locking point 24 fixedly connected to the outer surface of the cylindrical seat 22, a second magnet 25 fixedly connected to the inner top wall of the lamp holder 7, and a locking groove 26 opened on the inner wall of the lamp holder 7.
[0028] In practical use, the lamp holder 7, button battery 8, light source 9, cylindrical base 22, first magnet 23, locking point 24, second magnet 25, and locking groove 26 are arranged. The light source 9 is an LED light source. The lamp holder 7 is fixed inside the middle shell 1 by the magnetic attraction between the second magnet 25 and the first magnet 23, and by the cooperation between the locking point 24 and the locking groove 26. When fixing, the opening of the locking groove 26 is aligned with the locking point 24, and the bottom end of the lamp holder 7 is put on the cylindrical base 22, so that the first magnet 23 and the second magnet 25 are magnetically attracted together, completing the initial fixing of the lamp holder 7. Then, the lamp holder 7 is rotated so that the locking point 24 is turned into the tail of the locking groove 26, completing the fixing of the lamp holder 7. The lamp holder 7 contains four button batteries 8. The light source 9 is fixed to the lamp holder 7 with bolts. When replacing the drift light, the drift shell 2 can be unscrewed from the middle shell 1 to expose the light source 9. If only the light source 9 is to be replaced, the bolts are removed to separate the light source 9 from the lamp holder 7, a new light source 9 is installed, and it is then fixed back to the lamp holder 7 with bolts. The same procedure applies when replacing the button batteries 8. When replacing the entire lamp holder 7, rotate the lamp holder 7 along the locking groove 26, rotating the locking point 24 to the exit of the locking groove 26. Then, lift the lamp holder 7 to separate the first magnet 23 and the second magnet 25, allowing the entire lamp holder 7 to be removed, thus enabling the tail light to be displayed. When the float light malfunctions, anglers do not need to replace the entire float; only the damaged tail light needs to be replaced, thus avoiding resource waste and reducing operating costs. The float tail shell 2, float tail seat 3, and float tail extension seat 4 constitute the float tail. The float foot seat 5 and float foot extension seat 6 constitute the float foot. The float tail and float foot are assembled onto the middle shell 1 to form the float. Most of the structural components are connected by threads. When securing the fishing line to the float, the fishing line on the float foot first enters the through-hole 17 in the center of the float foot seat 5 and float foot extension seat 6. Simultaneously, the retaining pin 16 in the float foot extension seat 6 is inserted into the retaining groove 14 of the float foot seat 5, thus assembling the float foot seat 5 and float foot extension seat 6. After assembling the float and line, the line passes through both, allowing it to enter the inner ring seat 18 and pass through the line hole 21 to the outside of the inner ring seat 18. It then passes through another line hole 21 and re-enters the inner ring seat 18, ensuring that the end of the line hangs down beyond the inner ring seat 18. At this point, the float foot seat 5 is screwed in along the thread. After tightening, the line is firmly fixed inside the inner ring seat 18. The same method is used to fix the line in the float tail seat 3. Once fixed, the float foot and float tail are both fixed to the middle shell 1, completing the fixation of the float and line. This avoids the need to use the method of tying the line to fix the float and line, improving the fishing experience for novice users.
[0029] In this embodiment, the top of the inner wall of the middle shell 1 is provided with a first internal thread 10, and the bottom of the drift tail shell 2 is provided with a first external thread 11.
[0030] In practical use, the middle shell 1 and the drifting tail shell 2 are assembled and fixed together by setting the first internal thread 10 and the first external thread 11.
[0031] In this embodiment, the top of the inner wall of the float tail shell 2 and the bottom of the inner wall of the middle shell 1 are both provided with a second internal thread 12, and the outer surface of the float tail seat 3 and the outer surface of the float foot seat 5 are both provided with a second external thread 13.
[0032] In practical use, the float foot seat 5, the middle shell 1, the float tail shell 2, and the float tail seat 3 are assembled and fixed together by setting the second internal thread 12 and the second external thread 13.
[0033] In this embodiment, the ends of the float tail seat 3 and the float foot seat 5 that are far apart from each other are provided with a slot 14, and the outer surfaces of the ends of the float tail extension seat 4 and the float foot extension seat 6 that are close to each other are fixedly connected with a foot 16. The outer surfaces of the float tail seat 3 and the float foot seat 5 are provided with a pressing groove 15.
[0034] In actual use, the float tail seat 3 and float tail extension seat 4, as well as the float foot seat 5 and float foot extension seat 6 are assembled and fixed together by setting the clip 16 and the clip 14.
[0035] In this embodiment, a wire through hole 17 is provided at the center of the float tail seat 3, the float foot seat 5, the float tail extension seat 4, and the float foot extension seat 6.
[0036] In practical use, the line through hole 17 facilitates the entry of the fishing line into the float.
[0037] In this embodiment, the inner bottom wall of the float base 3 and the inner top wall of the middle shell 1 are both fixedly connected with an inner ring seat 18. The inner wall of the inner ring seat 18 is provided with a third internal thread 19. The bottom end of the float base 3 and the top end of the float foot seat 5 are both provided with a third external thread 20. The outer surface of the inner ring seat 18 is provided with a wire hole 21.
[0038] In practical use, the wire hole 21 facilitates wire threading.
[0039] Working principle: The light source 9 is an LED light source. The lamp holder 7 is fixed inside the middle shell 1 by the magnetic attraction of the second magnet 25 and the first magnet 23, as well as the cooperation of the locking point 24 and the locking groove 26. During fixing, the opening of the locking groove 26 is aligned with the locking point 24, and the bottom end of the lamp holder 7 is put on the cylindrical base 22, so that the first magnet 23 and the second magnet 25 are magnetically attracted together, completing the initial fixing of the lamp holder 7. Then, the lamp holder 7 is rotated so that the locking point 24 is turned into the tail of the locking groove 26, completing the fixing of the lamp holder 7. There are four button batteries 8 inside the lamp holder 7. The light source 9 is fixed by bolts and the lamp holder 7. When replacing the drift light, the drift housing 2 can be unscrewed from the middle housing 1 to expose the light source 9. If only the light source 9 is to be replaced, the bolts can be removed to separate the light source 9 from the lamp holder 7. Replace the new light source 9 and fix it back to the lamp holder 7 with bolts. The same applies when replacing the button battery 8. When replacing the entire lamp holder 7, rotate the lamp holder 7 along the locking groove 26 to rotate the locking point 24 to the exit of the locking groove 26. Then lift the lamp holder 7 to separate the first magnet 23 and the second magnet 25, and the entire lamp holder 7 can be removed for replacement.
