[0039] In the prior art, small flashlights fixed with lanyards and buckles are cumbersome to use because they are bound to keys, backpack chains, etc., and the lanyards and buckles are not detachable. When an emergency occurs and the flashlight needs to be used quickly, the user cannot quickly obtain the flashlight or disassemble the flashlight for free operation, resulting in a poor user experience.

[0040] Based on the above problems in the prior art, the present invention provides a quick-dial disassembly and assembly structure, such as Figure 1 、 Figure 5 As shown, the quick-dial disassembly and assembly structure includes: a main shell 100, on which a sleeve 200 is slidably provided; a locking member 300, which is arranged on one end of the main shell 100, and a mounting groove 310 is provided on the end of the locking member 300 facing away from the main shell 100, and a plurality of through holes 320 are circumferentially arranged on the locking member 300, which correspond to the positions of the through holes 320 and the mounting grooves 310, and a limiting member 321 is slidably provided in the through holes 320; an end cap 400, which includes a mounting column 410 that is plugged in and out of the mounting groove 310, and locking grooves 411 are provided on the mounting column 410 at positions corresponding to the plurality of through holes 320, and the locking grooves 411 are engaged and connected with the limiting member 321 along a predetermined arc surface; the end cap 400 includes a connecting member 420.

[0041] The present invention provides a through hole 320 corresponding to the installation groove 310 around one end of the locking piece 300, and slides a limiting piece 321 in the through hole 320, and provides a sleeve 200 on the main shell 100 fixedly connected to the locking piece 300. When the end cap 400 is installed, the locking groove 411 on the side of the mounting column 410 of the end cap 400 can be engaged with one side of the limiting piece 321, and the other side is limited and locked by the sleeve 200 to achieve locking; the user can actively move the sleeve 200 to release the lock on the limiting piece 321, so that the end cap 400 is quickly separated from the locking piece 300. When applied to a flashlight, it can prevent the flashlight from being lost and can be quickly disassembled for use, thereby improving the user experience.

[0042] In the above embodiment, if Figure 1 As shown, the main body of the quick-dial assembly and disassembly structure of the present invention is composed of a main housing 100, a sleeve 200, a locking member 300 and an end cap 400, wherein the sleeve 200 is connected to the main housing 100 and can slide on the main housing 100; the locking member 300 is provided on one end of the main housing 100, as shown in FIG. Figure 5As shown, a mounting groove 310 is provided on the locking member 300 at one end facing away from the main shell 100, and the mounting groove 310 is used for assembly and installation with the end cap 400. In this embodiment, a plurality of through holes 320 are also circumferentially provided on the locking member 300, and the positions of the plurality of through holes 320 correspond to the positions of the mounting groove 310, that is, the through holes 320 pass through the mounting groove 310 and the outer side of the locking member 300, and a limiting member 321 is provided inside the through hole 320, and the limiting member 321 is slidably provided inside the through hole 320 and can slide along the direction of the through hole 320 and a predetermined distance; correspondingly, a mounting post 410 is provided on the end cap 400, and the diameter size of the mounting post 410 is adapted to the diameter size of the mounting groove 310, so that the end cap 400 can be inserted into the mounting groove 310 through the mounting post 410 for assembly. Figure 1 and Figure 6 As shown, locking grooves 411 are further provided at positions corresponding to the plurality of through holes 320 on the mounting column 410. The locking grooves 411 are provided with predetermined arc surfaces, which can form corresponding snap fits with the arc surfaces at the ends of the above-mentioned limiting members 321, thereby enabling the locking grooves 411 to be snap-fitted and fixed to the limiting members 321 in all directions.

[0043] In this embodiment, the combination of the locking member 300 and the end cap 400 in the quick-dial assembly and disassembly structure has two states: locked and disassembled. Figure 2 As shown, in the locked state, the sleeve 200 moves to the extreme position toward the end cap 400, at which position the ends of several limiting members 321 can be limited, so that the limiting members 321 are fixed at the extreme position on the side of the through hole 320 toward the mounting groove 310. When the end cap 400 is assembled on the locking member 300, the extreme position of the limiting member 321 is exactly engaged with the locking groove 411 on the mounting column 410, thereby achieving the effect of firmly locking the end cap 400 on the locking member 300.

[0044] When the locking state is changed to the disassembly state, the user can move the sleeve 200 to move the sleeve 200 away from the end cap 400. At this time, the space at the outward end of the through hole 320 is opened, and the limit piece 321 can move freely along the through hole 320. When the user applies force to separate the main shell 100 and the end cap 400, the limit piece 321 and the locking groove 411 engaged with the arc surface are separated by tension and guided by the arc surface, thereby pushing several limit pieces 321, thereby releasing the engaging relationship. At this time, the end cap 400 and the locking piece 300 can be quickly separated; during installation, similarly, after the sleeve 200 is moved, the end cap 400 is pressed toward the locking piece 300, and the locking groove 411 and the end of the limit piece 321 are engaged by thrust and arc surface guidance, and then locking can be achieved by resetting the sleeve 200.

[0045] Based on the above embodiments, Figure 1As shown, a connecting piece 420 is also provided on the above-mentioned end cap 400, and the user can use the connecting piece 420 to fix the above-mentioned quick-dial disassembly structure as a whole to other structures, such as a backpack zipper, a key chain, etc. When the above-mentioned quick-dial disassembly structure is applied to a small flashlight, it can solve the problem that the small and medium-sized flashlights in the background technology of this application are cumbersome to use after being fixedly connected, and cannot be quickly obtained in an emergency. The flashlight cannot be disassembled for free operation, resulting in a poor user experience.

[0046] Based on the above embodiment, in order to prevent the above-mentioned limiting member 321 from moving along the through hole 320 and falling off during the unlocking process of the locking member 300 and the end cap 400, the matching position of the above-mentioned structure is also restricted in this embodiment, such as Figure 1 As shown, the above-mentioned limit member 321 is specifically set to be spherical, and is preferably made of a heavy and rust-resistant material such as a steel column to ensure that the limit member 321 can still slide smoothly after long-term use. At the same time, the limit member 321 set by the steel ball has a certain weight, which is convenient for quickly changing the displacement through inertia after being subjected to force, so as to assist the quick unlocking of the end cap 400 and the locking member 300.

[0047] A flange portion 330 is provided on the end of the locking member 300 away from the housing. The flange portion 330 is shaped like a flange and its function is to limit the movement range of one end of the sleeve 200. In addition, there is also a structure on the main housing 100 to limit the movement range of the other end of the sleeve 200 (detailed below). Correspondingly, a clearance ring 210 is provided at one end of the sleeve 200 corresponding to the flange portion 330. The clearance ring 210 is provided corresponding to the through hole 320, and its side facing the through hole 320 is provided with an inclined surface along a predetermined angle. Since the movement distance of the sleeve 200 is limited, as shown in FIG. Figure 2 As shown, when the sleeve 200 is in the extreme position facing the end cap 400, the thickest part of the give way ring 210 corresponds to the limit member 321, forming a limiting and locking position effect on the limit member 321; when the sleeve 200 is in the extreme position away from the end cap 400, the inclined surface on the give way ring 210 corresponds to the through hole 320. The inclined surface provides a movable space for the limit member 321 while limiting the extreme position of the limit member 321 and preventing the limit member 321 from falling off from the through hole 320.

[0048] Furthermore, in this embodiment, in order to achieve the effect of limiting the position of multiple limiting members 321 by the stop ring 210, the plurality of through holes 320 on the locking member 300 should be arranged on the same cross section of the locking member 300. In addition, the above structural arrangement only limits the limiting member 321 from falling off from the outer end of the through hole 320. In order to limit the limiting member 321 from falling off along the inner end of the through hole 320 after the end cap 400 is separated from the locking member 300, as shown in FIG. Figure 5As shown, a locking ring 322 is further provided at one end of the through hole 320 facing the mounting groove 310. The center of the locking ring 322 is the through hole 320, which is used to provide space for the limit member 321 to contact the locking groove 411. The diameter of the locking ring 322 is slightly smaller than the diameter of the through hole 320, and the shape of one side of the locking ring 322 facing the through hole 320 is adapted to the spherical shape of the limit member 321, thereby achieving the effect of limiting the extreme movement position of the limit member 321 at this end in the through hole 320.

[0049] In another embodiment of the present invention, Figure 1 and Figure 3 As shown, in order to make the sleeve 200 automatically reset and avoid repeated adjustments by the user to improve foolproofness, a reset spring 500 is also provided on the main housing 100 in this embodiment. Figure 3 The left end of the return spring 500 is called the fixed end. Figure 3 The other end of the return spring 500 on the right is called the adjustment end, wherein the fixed end of the return spring 500 is fixedly connected to the main shell 100, and the adjustment end of the return spring 500 is fixedly arranged in the interior of the sleeve 200 at a position corresponding to the yield ring 210; in the initial state, the return spring 500 is preset to abut the end of the sleeve 200 facing the end cap 400 against the flange portion 330, that is, in this state, the thickest part of the yield ring 210 corresponds to the limit member 321, so that the other side of the limit member 321 abuts against the lock ring 322 to protrude toward one side of the mounting groove 310; when the user moves the sleeve 200, the sleeve 200 slides along the main shell 100, and the return spring 500 accumulates elastic potential energy at this time. When the user cancels the force, the sleeve 200 is reset under the action of the elastic potential energy of the return spring 500, so as to prevent the user from forgetting to reset the sleeve 200, resulting in the locking member 300 and the end cap 400 being unsecured or incompletely combined.

[0050] In another embodiment of the present invention, Figure 1 and Figure 4As shown, since the return spring 500 is a torsion structure, in order to prevent the user from applying radial force when dialing the sleeve 200, causing the sleeve 200 and the main shell 100 to rotate relative to each other, resulting in failure of the return spring 500, in this embodiment, a plurality of sliding grooves 110 are further provided on the outer side of the main shell 100 along the length direction of the main shell 100, and the fixed end of the above-mentioned return spring 500 is located on the end of the sliding groove 110 facing the end cap 400, so as to achieve a fixing effect without affecting the function of the sliding groove 110, and the other end of the sliding groove 110 is closed, thereby limiting the length of the sliding groove 110; correspondingly, a plurality of sliding rails 220 are provided on the inner side of the sleeve 200 at positions corresponding to the plurality of sliding grooves 110, and the plurality of sliding rails 220 correspond to the plurality of sliding grooves 110 one by one and are slidably connected, so as to prevent the sleeve 200 and the main shell 100 from radially twisting while keeping the sleeve 200 and the main shell 100 able to slide along the length direction, thereby improving the service life of the above-mentioned return spring 500.

[0051] Furthermore, if Figure 4 As shown, when the sleeve 200 is specifically set, anti-slip ridges 230 can also be evenly set on the outside of the sleeve to increase the friction between the user's fingers and the outside of the sleeve 200, so as to facilitate the user to quickly turn the sleeve 200 with one hand. At the same time, it can also adapt to the user's firm grip in different environments, such as rain, snow and other bad weather conditions, so that the user can grasp it more easily.

[0052] In another embodiment of the present invention, Figure 1 and Figure 5 As shown, in order to assist the user in quickly inserting the mounting post 410 into the mounting groove 310 when installing the end cap 400 and the locking member 300, in this embodiment, a first magnetic member 430 is fixedly provided in the mounting post 410, and a second magnetic member 340 is fixedly provided in the mounting groove 310 to assist the user in quickly adjusting the corresponding position by magnetic attraction.

[0053] In a specific configuration, the first magnetic member 430 and the second magnetic member 340 can be configured as follows: one is a permanent magnet and the other is an original magnet, that is, one is a component with permanent magnetism such as a magnet, and the other is a component that can be attracted by a magnet but does not have magnetic force, such as an iron product.

[0054] In addition, the first magnetic part 430 and the second magnetic part 340 can also be set as: the first magnetic part 430 and the second magnetic part 340 are both permanent magnets, that is, both are magnets with permanent magnetism. In this embodiment, attention should be paid to the installation direction of the first magnetic part 430 and the second magnetic part 340, and it should be ensured that the magnetic poles of the opposing surfaces of the first magnetic part 430 and the second magnetic part 340 are opposite, so that the opposing surfaces of the two can achieve a guiding effect of mutual attraction.

[0055] In the above embodiment, since the first magnetic member 430 and the second magnetic member 340 have a mutual magnetic attraction, in order to prevent the first magnetic member 430 and the second magnetic member 340 from falling off after long-term use, Figure 1 and Figure 6 As shown, an assembly groove 412 is further provided at the center position of the mounting column 410, and the first magnetic component is fixedly arranged at the bottom of the assembly groove 412 in an interlocking manner; correspondingly, a positioning column 350 that is plug-in compatible with the assembly groove 412 is also provided at the center position of the mounting groove 310, and the above-mentioned second magnetic component 340 is interlocked inside the positioning column 350, so that the first magnetic component 430 and the second magnetic component 340 are not in direct contact, and both are constrained by the components to which they belong through the snap-fit ​​structure, thereby effectively preventing the first magnetic component 430 or the second magnetic component 340 from falling off after repeated use.

[0056] In this embodiment, in order to ensure smooth insertion and removal of the positioning column 350 and the assembly groove 412, and smooth insertion and removal of the installation column 410 and the installation groove 310, in this embodiment, guide surfaces are provided on the side corresponding to the assembly groove 412 and the side away from the assembly groove 412 at the end of the installation column 410. A guide surface is also provided at the end of the positioning column 350. The guide surface is an inclined surface with a certain inclination angle. Under the magnetic attraction of the first magnetic part 430 and the second magnetic part 340, combined with the inclined guiding effect of the guide surface, the end cap 400 and the locking part 300 can be quickly matched.

[0057] In one embodiment of the present invention, Figure 1 and Figure 6 As shown, the connecting member 420 is a lanyard buckle, which is integrally formed with the connecting member 420 to ensure structural strength. In the specific setting, the lanyard buckle should include at least one through hole 320 for fastening and fixing the lanyard in a knotted manner. In actual use, the lanyard can be tied with other structures (such as key chains, backpack zippers, etc.) to achieve firm binding and easy carrying.

[0058] In another possible embodiment of the present invention, the main shell 100 and the locking member 300 are detachably connected. The purpose of this arrangement is, on the one hand, to facilitate the installation of other accessories such as the sleeve 200, and on the other hand, to facilitate the installation of functional structures inside the main shell 100 so that the main shell 100 has specific functional roles. For example, a lamp group structure can be set inside the main shell 100 to form the main shell 100 into a small flashlight, or outdoor tools can be set inside the main shell 100, etc. The above-mentioned quick-dial disassembly and assembly structure can achieve the effect of being firm, portable, and quickly disassembled for use. In this embodiment, the specific structural arrangement inside the main shell 100 is not limited by this application, and those skilled in the art can apply the above-mentioned quick-dial disassembly and assembly structure according to actual design requirements.

[0059] In this embodiment, if Figure 1 and Figure 3 As shown, a first thread 120 is provided on the outer side of the main housing 100, and correspondingly, a second thread 360 is provided on the inner side of the locking member 300. The main housing 100 and the locking member 300 are rotationally connected by the first thread 120 and the second thread 360, which not only forms a fixed connection to limit the moving range of the sleeve 200 to ensure the normal use of the above-mentioned quick-dial assembly and disassembly structure, but also facilitates the installation, disassembly and repair of other functional structures in the main housing 100.

[0060] Based on the above embodiment, the complete assembly state of the quick-dial assembly and disassembly structure of the utility model is as follows Figure 2 As shown, in actual use, the entire quick-dial disassembly and assembly structure is installed on other structures through the connection piece 420 on the end cap 400 and the rope lock, which can achieve a portable and secure installation effect. When disassembly and use is required, the user only needs to dial the sleeve 200 to move the clearance ring 210 on the sleeve 200 relative to the through hole 320 on the locking piece 300, providing movement space for the limiting piece 321 in the through hole 320. The locking relationship between the locking groove 411 on the end cap 400 and the limiting piece 321 can be released by pulling, thereby achieving the effect of quickly separating the end cap 400 from the locking piece 300.

[0061] When the end cap 400 needs to be installed with the locking member 300, the sleeve 200 is also moved. Under the attraction of the first magnetic member 430 and the second magnetic member 340, the installation groove 310 on the locking member 300 and the installation column 410 on the end cap 400 are quickly aligned, and moved to a predetermined position so that the locking groove 411 corresponds to the limit member 321.
