Description

Technical Field

[0001] The utility model relates to the technical field of flashlight tail caps, and more specifically, to a multifunctional tail cap for a flashlight and a flashlight. Background Art

[0002] Most of the flashlight tail caps on the market at present do not have a cutter and cannot function to quickly cut a safety belt or a rope. If it is necessary to quickly cut a safety belt or a rope, corresponding equipment needs to be equipped additionally; for the tail cap equipped with a cutter, the cutter is fixed on the side of the tail cap. Although it has the cutter function, since the cutter is fixed on the outside, it will cause the tail cap to be bulky or produce a phenomenon of being prickly to the hand. In the application of a service flashlight, due to the provision of a fixing sleeve for assembling the flashlight, if a cutter is installed on the side of the tail cap, it cannot be used in compatibility with a conventional fixing sleeve, resulting in inconvenient carrying of the service flashlight. Summary of the Utility Model

[0003] The purpose of the utility model is to overcome the problems that the flashlight tail cap does not have a cutter function or the tail cap with a cutter function cannot match the original flashlight fixing sleeve, and to provide a multifunctional tail cap for a flashlight. On the basis of having a cutter function, the flashlight can be adapted to the original fixing sleeve, solving the problem of inconvenient carrying of the service flashlight.

[0004] To achieve the above purpose, the technical solution adopted by the utility model is:

[0005] A multifunctional tail cap for a flashlight, comprising a housing, a lid, a cutter, and a rotating shaft. A receiving groove and an installation groove that communicate with each other are formed in the lid. The receiving groove and the installation groove are vertically arranged. The installation groove is hidden between the lid and the housing, and the receiving groove is exposed on the surface of the lid. The rotating shaft is disposed in the installation groove and is rotatably connected to the installation groove. The cutter can be located in the receiving groove and is connected to the rotating shaft; the lid is covered on the housing and is detachably connected to the housing; in the storage state, the cutter is located in the receiving groove; in the use state, the cutter can be flipped along the rotating shaft to protrude from the surface of the lid.

[0006] The housing and the lid of the present utility model are detachably connected, specifically, it can be screw connection, threaded connection, etc.; an installation space for the rotating shaft is formed between the lid and the housing, the cutter is fixedly connected to the rotating shaft, and is rotationally connected to the installation groove on the lid through the rotating shaft, so as to drive the cutter to be able to flip relative to the lid; when the cutter is in the storage state, the cutter is placed in the receiving groove and does not protrude from the surface of the lid. At this time, the phenomenon that the cutter pricks the hand in the prior art can be overcome, and the hidden setting of the cutter can make the end cap not look bloated. Moreover, since the cutter does not occupy extra space, the flashlight can still be accommodated in the fixing sleeve. The cutter setting of the present utility model makes the end cap highly compatible, and the end cap not only realizes the functions of an ordinary end cap, but also has a cutting function, realizing the versatility of the end cap; when the cutter is in the use state, the cutter rotates along with the rotating shaft. At this time, the end of the lid far from the cutter rotates with the rotating shaft as the axis, the cutter flips relative to the lid, and the cutter protrudes from the surface of the lid. Usually, when the cutter is rotated to be perpendicular to the lid, the distance from the end of the cutter far from the rotating shaft to the lid is the largest at this time, which is convenient for the use of the cutter and can utilize the cutter to realize the cutting function.

[0007] Further, the end of the cutter far from the rotating shaft is a hook-shaped structure. The cutter with a hook-shaped structure is convenient for cutting.

[0008] Further, the end of the cutter is a thin structure. The cutter with a thin structure can be used as a flat screwdriver, further increasing the versatility of the end cap.

[0009] Further, a use limiting part is provided on the rotating shaft, and a matching limiting part is provided on the housing at the bottom of the rotating shaft. The use limiting part can be clamped and limited with the matching limiting part. The use limiting part limits the position of the cutter when the cutter is in the use state, which is specifically realized by the clamping connection between the use limiting part and the matching limiting part, and can make the cutter maintain the set position without changing.

[0010] Further, a storage limiting part is also provided on the rotating shaft. The storage limiting part is arranged in a dislocation manner with the use limiting part, and the storage limiting part can also be clamped and limited with the matching limiting part. The storage limiting limits the position of the cutter when the cutter is in the storage state. At this time, the cutter is located in the receiving groove, that is, the hidden state of the cutter. The clamping connection between the storage limiting part and the matching limiting part is used to make the cutter maintain the position of not protruding from the surface of the lid, which does not affect the conventional functions of the end cap and is convenient for the carrying of the flashlight.

[0011] Further, the central axis of the use limiting part is vertically arranged with the central axis of the storage limiting part. When the cutter is in the position perpendicular to the lid, it is the optimal use position of the cutter. At this time, it is beneficial to the cutting force application of the cutter. When storing, the cutter and the lid are in the same horizontal plane. At this time, the cutter is embedded in the receiving groove of the lid. Therefore, setting the central axis of the use limiting part perpendicular to the central axis of the storage limiting part is beneficial to the use and storage of the cutter.

[0012] Furthermore, both the use limiting part and the storage limiting part are grooves, and the matching limiting part is an elastic protrusion. Preferably, the groove is an arc structure. The limiting function can be realized by using the depression and the protrusion for clamping. By setting the protrusion as an elastic structure, it is convenient for the rotating shaft to rotate between the use limiting part and the storage limiting part. When the use limiting part is aligned with the matching limiting part or the storage limiting part is aligned with the matching limiting part, the elastic protrusion can be inserted into the groove for clamping and limiting; when the rotating shaft is rotated to misalign the use limiting part with the matching limiting part or misalign the storage limiting part with the matching limiting part, the elastic protrusion can be compressed into the installation position of the housing under the pressure of the rotating shaft, which will not affect the normal rotation of the rotating shaft and is beneficial to realizing the rotation function of the rotating shaft.

[0013] Furthermore, the matching limiting part includes a ball and a spring. There is an installation position on the housing. One end of the spring is connected to the bottom of the installation position, and the other end is connected to the ball. Preferably, the ball is a steel ball; the ball is a spherical structure, and the ball is matched with the arc groove. The spring has an elastic force, which can realize ejecting the ball out of the installation position and inserting it into the use limiting part or the storage limiting part for clamping and limiting, or when the spring is compressed, the ball is hidden in the installation position to avoid it during the rotation of the rotating shaft. The installation position is a groove opened on the housing.

[0014] Furthermore, a magnetic attraction element for attracting the cutter is provided at the end of the cover or the housing away from the rotating shaft. The magnetic attraction element can be a magnet, and the cutter is made of a metal material. The magnetic attraction element can be used to adsorb and fix the cutter in the storage state, so that the cutter will not automatically rotate and turn out.

[0015] Furthermore, a flexible limiting member for limiting in the storage state of the cutter is installed on the side of the cover located in the receiving groove. Preferably, the flexible limiting member is a silica gel pad. The silica gel pad is protruded from the receiving groove, so that an interference is formed between the flexible limiting member and the cutter during the rotation process of the cutter from the storage state to the use state, ensuring that the cutter is not easily rotated and turned out automatically in the storage state; the flexible limiting member can add an additional layer of safety guarantee on the basis of the magnetic attraction element to prevent the cutter from being automatically opened; on the other hand, due to the characteristic that the flexible limiting member deforms after being stressed, when the cutter is manually rotated and turned out, as long as a certain friction force is slightly overcome, the cutter can turn over and protrude from the cover to perform cutting.

[0016] The present utility model also provides a flashlight, which includes a flashlight body and the multifunctional tail cap for the flashlight as described above, and the tail cap is detachably connected to the flashlight body. The flashlight provided with a cutter has a cutting function while having a common lighting function, which is beneficial to improving the diversity of the use of the flashlight.

[0017] The beneficial effects of the present utility model are:

[0018] By flipping the cutting knife, when the cutting knife is not in use, the cutting knife is hidden in the cover and does not protrude from the cover surface, which has the advantages of not being scratchy, not being bulky, and having strong flashlight compatibility; when the cutting knife is in the storage state, the matching limit part and the storage limit part are engaged and limited so that the shaft cannot rotate, and the cutting knife is sucked by the magnetic element so that the cutting knife will not automatically rotate and turn out. At the same time, the flexible limit part can limit the cutting knife, adding multiple protections to prevent the cutting knife from automatically turning over and opening, thereby improving product safety;

[0019] When using the cutter, the end of the cutter away from the shaft is flipped. After the cutter is flipped to a fixed angle, the limiting part and the matching limiting part are used to engage and limit the position. At this time, the cutter shaft can support the tail cover and will not flip over, making it more secure to use. BRIEF DESCRIPTION OF THE DRAWINGS

At this time, the phenomenon that the cutter 3 pricks the hand in the prior art can be overcome, and the hidden setting of the cutter 3 can make the end cap not look bulky. Moreover, since the cutter 3 does not occupy extra space, the flashlight can still be accommodated in the fixing sleeve. The setting of the cutter 3 of the present utility model makes the end cap highly compatible, and the end cap not only realizes the functions of an ordinary end cap but also has a cutting function, realizing the versatility of the end cap; when the cutter 3 is in the use state, the cutter 3 rotates along with the rotating shaft 4. At this time, the end of the lid 2 far from the cutter 3 rotates with the rotating shaft 4 as the axis, the cutter 3 flips relative to the lid 2, and the cutter 3 protrudes from the surface of the lid 2. Usually, when the cutter 3 is rotated to be perpendicular to the lid 2, the distance from the end of the cutter 3 far from the rotating shaft 4 to the lid 2 is the largest, which is convenient for the use of the cutter 3, and the cutting function can be realized by using the cutter 3. Preferably, the receiving groove 21 is arranged in the middle of the lid 2, so that the cutter 3 can be set to the largest volume, and a slightly larger cutter 3 is beneficial to improving the cutting performance.

[0032] As an improved scheme of this embodiment, the end of the cutter 3 far from the rotating shaft 4 is a hook-shaped structure. The cutter 3 with a hook-shaped structure is convenient for cutting.
