[0061] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions of the embodiments of the present application will be described clearly and completely below with reference to the drawings of the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the described embodiments of the present application, all other embodiments obtained by a person of ordinary skill in the art without any inventive effort fall within the scope of protection of the present application.

[0062] Unless otherwise defined, technical terms or scientific terms used in the present application shall have the common meaning understood by a person of ordinary skill in the art to which the present application pertains. The terms “first”, “second” and similar words used in the present application do not represent any order, number or importance, but are only used to distinguish different components. The terms “include” or “contain” and similar words mean that the components or objects before the words cover the components or objects listed after the words and their equivalents, without excluding other components or objects. The terms “connect” or “connected” and similar words are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. The terms “up”, “down”, “left”, “right” and the like only represent relative positional relationships, which can change accordingly when the absolute positions of the described objects change.

[0063] In order to keep the following description of the embodiments of the present application clear and concise, the present application omits the detailed description of known functions and known components.

[0064] First of all, it should be noted that the present application is applicable to any device that can be worn on the head of a user, including but not limited to, for example, night vision devices, headlamps, night vision telescopes, etc. For the convenience of description, the following will be described by taking a night vision device as an example. The night vision device includes but is not limited to low-light-level night vision devices, infrared night vision devices, fusion glasses, etc.

[0065] This application provides a sliding locking mechanism that can be used on a flip bracket to move a night vision device (not shown in the figure) to adjust the distance between the night vision device and the user's eyes, so that the night vision device is in a comfortable position for the user.

[0066] like Figures 1 to 7 As shown, the sliding locking mechanism of this application embodiment includes a guide rail 11, a sliding seat 12, and a first locking component 13. The guide rail 11 has at least one row of first positioning holes 111 along its extending direction, and each row includes multiple first positioning holes 111. The sliding seat 12 is disposed on the guide rail 11 and can slide along the guide rail 11. The sliding seat 12 has at least one first through hole 122 corresponding to the number of rows of the first positioning holes 111. When the sliding seat 12 slides along the guide rail 11, the first through hole 122 can sequentially align with the multiple first positioning holes 111 located in the same row. The first locking component 13 is disposed on the sliding seat 12 and includes a first locking member. The first locking member has a locked state and an unlocked state. In the locked state, the first locking member is simultaneously confined within the opposite first positioning hole 111 and first through hole 122 to lock the sliding seat 12 onto the guide rail 11. In the unlocked state, the first locking member disengages from the first positioning hole 111, releasing the sliding seat 12 from the guide rail 11 and allowing the sliding seat 12 to slide along the guide rail 11.

[0067] The sliding locking mechanism of this application embodiment provides a first positioning hole 111 on the guide rail 11 and a first through hole 122 on the sliding seat 12 that cooperates with the first positioning hole 111. By using a first locking member that can be simultaneously inserted into the first positioning hole 111 and the first through hole 122, or disengaged from the first positioning hole 111 and only located in the first through hole 122, the sliding seat 12 can be locked and fixed on the guide rail 11. The above structure is simple and reasonable, and the first locking member and the first positioning hole 111 are tightly fitted. In the locked state, there will be no shaking, ensuring the effectiveness of the night vision device.

[0068] It can be understood that the specific structure of the first locking member is not limited, as long as it can be adapted to the first through hole 122 and the first positioning hole 111, and can smoothly and smoothly enter and exit the first positioning hole 111. For example, the first locking member can be a ball, the diameter of the ball is smaller than the diameter of the first through hole 122, but larger than the hole diameter of the first positioning hole 111, so that the ball can freely move in the axial direction of the first through hole 122, but cannot fall away from the side of the first through hole 122 when the first positioning hole 111 is a through hole. The ball can only partially enter the first positioning hole 111, so that the ball can smoothly exit the first positioning hole 111 in the direction of the first through hole 122 in the unlocked state. For another example, the first locking member can be a short cylinder (pintle), one end of which facing the first positioning hole 111 is a spherical surface. The radial dimension of the short cylinder is smaller than the hole diameter of the first through hole 122, so that the short cylinder can freely move in the axial direction of the first through hole 122. The diameter of the spherical surface of one end of the short cylinder is larger than the hole diameter of the first positioning hole 111 and can only partially enter the first positioning hole 111, so that one end of the short cylinder can smoothly exit the first positioning hole 111 in the direction of the first through hole 122 in the unlocked state, and the short cylinder cannot fall away from the side of the first through hole 122 when the first positioning hole 111 is a through hole. For the convenience of description, the first locking ball 131 will be taken as an example in the following description, since the action principle of the first locking member as a short cylinder is the same as that of the ball, the application will not make a specific introduction to the first locking member as a short cylinder. In addition, the material of the first locking member is not limited, and can be selected from, for example, metal or hard plastic.

[0069] In some embodiments, as Figure 2 and Figure 5As shown, the first locking assembly 13 comprises a first locking ball 131, a first button 132 and a first reset member 133. The first locking ball 131 is movably arranged in the first through hole 122 of the sliding seat 12. The first button 132 is arranged on the sliding seat 12 and has a first pushing inclined surface 1321. The first button 132 is movable relative to the sliding seat 12 to have a pressing state and a releasing state. When the first button 132 is in the releasing state, the first pushing inclined surface 1321 presses against the first locking ball 131, so that the first locking ball 131 partially enters the first positioning hole 111 to lock the sliding seat 12 on the guide rail 11, and the sliding seat 12 cannot slide relative to the guide rail 11. When the first button 132 is in the pressing state, the first pushing inclined surface 1321 releases the pressing action on the first locking ball 131, the first locking ball 131 can be pulled out of the first positioning hole 111, and the locking of the sliding seat 12 is released, so that the sliding seat 12 can slide along the guide rail 11. The first reset member 133 acts on the first button 132 to apply a force to the first button 132 to reset it from the pressing state to the releasing state. The first locking assembly 13 of the embodiment has a simple and reasonable structure, is convenient to control, and can realize the locking and unlocking of the sliding seat 12 on the guide rail 11 by pressing the first button 132 with one hand. When the first button 132 is in the releasing state, the guide rail 11 is pressed against the first locking ball 131 to the first pushing inclined surface 1321 under the action of the first reset member 133, which plays a role in eliminating clearance and enhancing damping, preventing the sliding locking mechanism from affecting position adjustment due to shaking caused by rapid rotation when applied to a turnover support.

[0070] In some embodiments, the sliding seat 12 comprises a seat body 121 and a protruding part 125. The seat body 121 is slidably arranged on the guide rail 11 and can drive the protruding part 125 to slide along the guide rail 11. The first through hole 122 is arranged on the seat body 121 and has a side hole opening facing the guide rail 11. During the sliding process of the seat body 121, the hole opening can be sequentially opposite and communicated with the plurality of first through holes 122 on the first guide rail 11. The protruding part 125 is arranged on the side of the seat body 121 away from the guide rail 11 and has a first button cavity 126 penetrating to the peripheral side thereof. The first button 132 is arranged in the first button cavity 126 and is movable in the axial direction perpendicular to the guide sliding hole 123. The first button cavity 126 is communicated with the first through hole 122, so that the first locking ball 131 in the first through hole 122 can extend into the first button cavity 126 and be switched between the locking state and the unlocking state under the action of the first pushing inclined surface 1321 when the first button 132 is pressed or released, to realize the locking and unlocking of the seat body 121.

[0071] It can be understood that the specific structure of the guide rail 11 is not limited, as long as the sliding seat 12 can slide thereon. The specific structure of the guide rail 11 and the sliding seat 12 will be described in detail in different embodiments.

[0072] Embodiment One

[0073] As shown in Figure 1 and Figure 2 , the guide rail 11 includes a base 112 and two convex edges 113 arranged in parallel on the base 112, and a plurality of first positioning holes 111 are arranged in the axial direction of each convex edge 113 in sequence, and the plurality of first positioning holes 111 on the two convex edges 113 are arranged one by one in correspondence, wherein the first positioning hole 111 can be a through hole or a blind hole, and the present embodiment does not make specific limitation.

[0074] As shown in Figure 3 , the seat body 121 of the sliding seat 12 is provided with a guide sliding groove 124, and the seat body 121 is arranged on the base 112 through the guide sliding groove 124, and the opposite two groove side walls of the guide sliding groove 124 are respectively in sliding fit with the opposite two side portions of the base 112. That is, the two side portions of the base 112 respectively form dovetail portions, and the two groove side walls of the guide sliding groove 124 respectively form dovetail grooves, and the dovetail portions are embedded into the dovetail grooves, so that the sliding seat 12 is limited on the base 112 and can slide along the base 112, but cannot be detached from the base 112. The seat body 121 of the sliding seat 12 is provided with first through holes 122 corresponding to the first positioning holes 111 on the two convex edges 113 respectively.

[0075] Continuing to combine Figure 3 , the convex portion 125 and the seat body 121 can be an integral structure or a split structure, and the present application does not make specific limitation thereon. The convex portion 125 of the sliding seat 12 has two first button cavities 126, and the two first button cavities 126 respectively penetrate to the opposite two sides of the convex portion 125. That is, one end of the first button cavity 126 is open, and the other end is blocked. The direction from one end of the first button cavity 126 to the other end is perpendicular to the extension direction of the convex edge 113. It can be understood that the convex portion 125 of Embodiment Two can also be considered to be combined by two separate convex portions, and the sides away from each other of the two convex portions are respectively provided with the first button cavities 126. The first button 132 is arranged into the first button cavity 126 from the open end. The two first button cavities 126 are respectively provided with the first button 132.

[0076] The first reset member 133 can adopt a spring, in order to avoid the first push-in inclined surface 1321 and avoid affecting the action of the first push-in inclined surface 1321 on the first locking ball 131, the spring can be arranged in the first button 132.

[0077] The first button 132 comprises a first end 1322 for pressing and a second end 1323 away from the first end 1322. An inner hole 1326 is formed in the first button 132, which extends to the second end 1323 and forms an opening. A first return member 133 is arranged in the inner hole 1326, one end of which abuts the bottom of the inner hole 1326 and the other end abuts the closed end of the first button cavity 126. When the first button 132 is in the pressed state, the first return member 133 is compressed and accumulates elastic potential energy. When the first button 132 is released, the first return member 133 releases the elastic potential energy and pushes the first button 132 to move towards the direction away from the first button cavity 126.

[0078] As shown in Figure 4 The first button 132 further comprises a bottom side 1324 facing the bottom side of the first through hole 122 and a first side and a second side connected to the bottom side 1324 respectively. The bottom side 1324 is partially recessed inward to form a groove 1325, which extends to the first side and the second side of the first button 132. The groove wall of the groove 1325 away from the first end 1322 of the first button 132 gradually inclines from the groove bottom to the groove opening to form a first pushing inclined surface 1321 towards the direction of the second end 1323 of the first button 132.

[0079] When it is necessary to adjust the position of the sliding seat 12 on the guide rail 11, the first ends 1322 of the two first buttons 132 are pressed at the same time, the two first return members 133 are compressed at the same time, the first pushing inclined surfaces 1321 on the two first buttons 132 move towards the direction away from the first through hole 122 at the same time, and the two first buttons 132 simultaneously release the pressure on the respective first locking balls 131, wherein the moving direction of the first pushing inclined surfaces 1321 is perpendicular to the extension direction of the guide rail 11. The two first pushing inclined surfaces 1321 simultaneously release the pressure on the respective first locking balls 131, so that the first locking balls 131 can move in the axial direction of the first through hole 122. When the sliding seat 12 is pushed to slide along the guide rail 11, under the action of the sliding seat 12, the part of the first locking ball 131 located in the first positioning hole 111 will be pulled out of the first positioning hole 111 and move together with the sliding seat 12. When the sliding seat 12 moves to the desired position, the pressure on the two first buttons 132 is simultaneously released, the two first buttons 132 are switched to the released state under the action of the respective first return members 133, the first pushing inclined surfaces 1321 move towards the direction close to the first through hole 122 and press on the respective corresponding first locking balls 131, so that the first locking balls 131 partially extend into the first positioning hole 111 (see Figure 2 and Figure 7), under the joint action of the opposite direction forces exerted by the first pushing slope 1321 and the hole wall of the first positioning hole 111 on the first locking ball 131, the first locking ball 131 is stably kept in the locking state, and the sliding seat 12 is locked on the guide rail 11, and not only cannot slide relative to the guide rail 11, but also cannot shake or sway even when rapid overturning occurs.

[0080] The first embodiment can make the sliding seat 12 more stably locked on the guide rail 11 by the double-row first positioning hole 111 and the control of the double buttons, and the locking effect is excellent.

[0081] It can be understood that, corresponding to each row of the first positioning hole 111 on the guide rail 11, only one first through hole 122 and one first locking ball 131 can be arranged, or two or more first through holes 122 and two or more first locking balls 131 matched with the number of the first through holes 122 can be arranged. When two or more first through holes 122 and two or more first locking balls 131 are arranged, in the locking state, two or more first locking balls 131 are respectively corresponded to make the first locking ball 131 partially enter the first positioning hole 111. By arranging two or more first through holes 122 and two or more first locking balls 131, the fastening after locking can be further improved, and the shaking phenomenon due to loosening can be avoided.

[0082] Optionally, in order to simplify the structure under the premise of ensuring the locking effect, two first through holes 122 can be arranged on the sliding seat 12, and the two first through holes 122 are arranged along the moving direction of the sliding seat 12. The locking assembly includes two first locking balls 131, and the two first locking balls 131 are correspondingly arranged in the two first through holes 122. When the first pushing slope 1321 on the first button 132 can simultaneously act on the two first locking balls 131, that is, the two first locking balls 131 can synchronously move under the action of the same first button 132. In order to make the first pushing slope 1321 on the same first button 132 simultaneously act on the two first locking balls 131, the size of the first pushing slope 1321 in the sliding direction of the sliding seat 12 needs to be increased to simultaneously cover the two first locking balls 131. Of course, two identical first pushing slopes 1321 can also be designed on the same first button 132 to respectively push the two first locking balls 131, but it needs to be ensured that the two first pushing slopes 1321 can make the two first locking balls 131 keep synchronous movement.

[0083] When the first button 132 is in the released state, the two first locking balls 131 can correspond to the two adjacent first positioning holes 111 on the guide rail 11 respectively, or the two first positioning holes 111 spaced apart, so that part of the two first locking balls 131 can enter the two adjacent or spaced apart first positioning holes 111 respectively. As shown in Figure 2 the embodiment, the two first locking balls 131 can enter the two spaced apart first positioning holes 111 respectively, which can increase the positioning length and improve the locking effect.

[0084] Embodiment Two

[0085] The difference between embodiment two and embodiment one is mainly in the structure of the guide rail 11 and the sliding seat 12 and the number of rows of first positioning holes 111.

[0086] As shown in Figure 5 and Figure 6 , the guide rail 11 is in the form of a rod, which can be a hollow rod or a solid rod. In order to reduce the weight and improve the comfort when worn on the head, the rod is preferably designed as a hollow rod. The guide rail 11 is provided with a plurality of first positioning holes 111 arranged in sequence in the axial direction thereof, that is, the guide rail 11 is provided with a row of first positioning holes 111 in the axial direction thereof. The seat body 121 of the sliding seat 12 is provided with a guide sliding hole 123 matched with the guide rail 11, and the seat body 121 is sleeved on the guide rail 11 through the guide sliding hole 123.

[0087] The seat body 121 of the sliding seat 12 is provided with a protruding portion 125, and the protruding portion 125 is provided with a first button cavity 126 penetrating to the peripheral side thereof, that is, one end of the first button cavity 126 is open, and the other end is blocked. The direction from one end of the first button cavity 126 to the other end is perpendicular to the extension direction of the guide rail 11. The first button 132 is installed into the first button cavity 126 from the open end. The action process and principle of the first button 132 in the first button cavity 126 in embodiment two, and the cooperation relationship with the first locking ball 131 are the same as those in embodiment one, and will not be described here.

[0088] It should be noted that in order to avoid the rotation of the sliding seat 12 around the rod-shaped guide rail 11, an anti-rotation structure can be provided between the two, for example, the side of the guide rail 11 away from the side where the first positioning holes 111 are arranged is designed as a non-arc surface, that is, a multi-plane connection form, and the hole wall of the guide sliding hole 123 corresponding to the non-arc surface part of the guide rail is also designed as a corresponding multi-plane form. For another example, corresponding concave-convex structures are arranged on the outer peripheral wall of the guide rail 11 and the hole wall of the guide sliding hole 123, and the rotation of the sliding seat 12 is limited by the cooperation of the concave-convex structures. It can be understood that no matter what form of anti-rotation structure is used, it will not affect the sliding of the sliding seat 12 on the guide rail 11.

[0089] The application also provides a flip support, as shown in Figures 8 to 10 The flip support comprises a rotating locking mechanism 30 and two sliding locking mechanisms, i.e., the first sliding locking mechanism 10 and the second sliding locking mechanism 20.

[0090] The flip support of the application has the advantages of stable structure and high reliability, and will not shake even when flipped too fast, thus improving the user experience.

[0091] In some embodiments, as shown in Figures 11 to 13 The rotating locking mechanism 30 comprises a rotating member 31, a fixed member 32 and a second locking assembly 33. The rotating member 31 is connected with the guide rail 11 of the first sliding locking mechanism 10 and has at least one second through hole 3111 around the outer periphery thereof. The fixed member 32 is connected with the sliding seat 12 of the second sliding locking mechanism 20 and has a through hole 3211, the fixed member 32 is sleeved outside the rotating member 31 through the through hole 3211, and at least one set of second positioning holes corresponding to the at least one second through hole 3111 are arranged on the hole wall of the through hole 3211. The second locking assembly 33 is arranged on the rotating member and comprises a second locking piece, the second locking piece has a locking state and an unlocking state, in the locking state, the second locking piece is simultaneously positioned in at least one of the at least one second through hole 3111 and the set of second positioning holes corresponding thereto, so as to lock the rotating member 31 on the fixed member 32; in the unlocking state, the second locking piece is out of the second positioning hole, and the locking of the rotating member 31 on the fixed member 32 is released, so that the rotating member 31 can rotate relative to the fixed member 32.

[0092] The rotating locking mechanism 30 of the application can lock the rotating member 31 on the fixed member 32 by arranging the second positioning hole on the fixed member 32 and the second through hole 3111 cooperating with the second positioning hole on the rotating member 31, and using the second locking piece which can be simultaneously positioned in the second positioning hole and the second through hole 3111 or out of the second positioning hole and only in the second through hole 3111, the structure is simple and reasonable, the second locking piece and the second positioning hole cooperate closely, the locking effect is better, and the stability is high.

[0093] The specific structure of the second locking member is not limited, as long as it can be adapted to the second through hole 3111 and the second positioning hole, and can smoothly and smoothly enter and exit the second positioning hole. For example, the second locking member can be a ball, the diameter of the ball is smaller than the diameter of the second through hole 3111, but larger than the hole diameter of the second positioning hole, so that the ball can freely move in the axial direction of the second through hole 3111, but cannot fall away from the side of the second positioning hole (when the second positioning hole is a through hole) away from the second through hole 3111. The ball can only partially enter the second positioning hole, so that in the unlocked state, the ball can smoothly exit the second positioning hole towards the direction of the second through hole 3111. For another example, the second locking member can be a short cylinder, one end of which towards the second positioning hole is a spherical surface. The radial dimension of the short cylinder is smaller than the hole diameter of the second through hole 3111, so that the short cylinder can freely move in the axial direction of the second through hole 3111. The diameter of the spherical surface of one end of the short cylinder is larger than the hole diameter of the second positioning hole, and can only partially enter the second positioning hole, so that in the unlocked state, one end of the short cylinder can smoothly exit the second positioning hole towards the direction of the second through hole 3111, and the short cylinder cannot fall away from the side of the second positioning hole (when the second positioning hole is a through hole) away from the second through hole 3111. For the convenience of description, the following will take the second locking ball 331 as an example, which is a ball. Since the action principle of the second locking member as a short cylinder is the same as that of the ball, the application will not make a specific introduction to the second locking member as a short cylinder. In addition, the material of the second locking member is not limited, which can be selected from, for example, metal or hard plastic.

[0094] In some embodiments, as Figure 12 and Figure 13As shown, the second locking element is a second locking ball 331. The number of second locking balls 331 is the same as the number of second through holes 3111, and they are movably disposed in the second through holes 3111 in a corresponding manner. The second locking assembly 33 also includes a second button 333 and a second reset element 332. The second button 333 is disposed on the rotating member 31 and has a second pushing inclined surface 3333. The second button 333 can move relative to the rotating member 31 and has a pressed state and a released state. When the second button 333 is in the released state, the second pushing inclined surface 3333 presses against the second locking ball 331, causing part of the second locking ball 331 to enter the second positioning hole, thereby locking the rotating member 31 onto the fixed member 32, so that the rotating member 31 cannot rotate relative to the fixed member 32. When the second button 333 is pressed, the second pushing slope 3333 releases its pressing action on the second locking ball 331, causing the second locking ball 331 to disengage from the second positioning hole and release the lock on the rotating member 31, allowing the rotating member 31 to rotate relative to the fixed member 32. The second reset member 332 acts on the second button 333 to apply a force to reset the second button 333 from the pressed state to the released state. The second locking component 33 of this embodiment has a simple and reasonable structure and is easy to operate. The locking and unlocking of the rotating member 31 on the fixed member 32 can be achieved by pressing the second button 333 with one hand.

[0095] In some embodiments, such as Figure 14 As shown, the fixing member 32 includes a bushing 321, and a second positioning hole is provided on the inner wall of the bushing 321. The axis of the positioning hole is consistent with the radial direction of the bushing 321.

[0096] like Figure 15 As shown, the rotating component 31 includes a shaft 311. The shaft 311 has a shaft hole 3112 extending to one end in its axial direction. A second through hole 3111 is located on the outer peripheral wall of the shaft 311 and communicates with the shaft hole 3112. A second button 333 is located within the shaft hole 3112 and can move along the axial direction of the shaft hole 3112 to switch between a pressed state and a released state. The structural design of the fixing component 32 and the rotating component 31 is ingenious, simple, and reasonable, reducing manufacturing difficulty and resulting in lighter weight and improved wearing comfort.

[0097] In some embodiments, such as Figure 16As shown, the second button 333 includes a stem part 3331 arranged in the shaft hole 3112 and a pressing part 3335 exposed outside the shaft hole 3112, the stem part 3331 includes a thin diameter section, a thick diameter section, and a frustum section 3332 for connecting the thin diameter section and the thick diameter section, the thin diameter section is close to the pressing part 3335 relative to the thick diameter section, the small diameter end of the frustum section 3332 is connected with the thin diameter section, the large diameter end of the frustum section 3332 is connected with the thick diameter section, and the outer circumferential surface of the frustum section 3332 forms a second pushing inclined surface 3333. The machining method for designing the frustum section 3332 of the stem part 3331 of the second button 333 to form the second pushing inclined surface 3333 is simple, and is beneficial to the effective cooperation between the second pushing inclined surface 3333 and the second locking ball 331.

[0098] The second reset member 332 can be a spring, in order to avoid the second pushing inclined surface 3333 and avoid affecting the action of the second pushing inclined surface 3333 on the second locking ball 331, the spring can be arranged in the second button 333. Specifically, as shown in Figure 13 As shown, the end of the stem part 3331 of the second button 333 away from the pressing part 3335 is provided with a blind hole 3334 inside, the second reset member 332 is arranged in the blind hole 3334, one end of the second reset member 332 abuts against the hole bottom of the blind hole 3334, and the other end abuts against the hole bottom of the shaft hole 3112 of the shaft 311. When the second button 333 is in a pressed state, the second reset member 332 is compressed and accumulates elastic potential energy, and when the second button 333 is released, the elastic potential energy is released, and the second button 333 is pushed to move in the direction away from the shaft hole 3112.

[0099] It can be understood that the number of the second locking balls 331 in the second locking assembly 33 is not limited, and the locking is performed by using the cooperation of multiple second locking balls 331, which can improve the stability, and when too many second locking balls 331 are arranged, the complexity of the structure will be increased, and the cost and weight will also be increased. The application is preferably described by taking two second locking balls 331 as an example, and for the convenience of description, the two second locking balls 331 are defined as a second locking ball 331A and a second locking ball 331B.

[0100] The number of the second positioning holes in each group of the second positioning holes is different according to the number of the positions needed to be positioned in the folding process of the first sliding locking mechanism 10, for example, when the first sliding locking mechanism 10 only needs to be in the folded state (see Figure 10 ) and the unfolded state (see Figure 8When switching between the two positions, each group only needs to include two second positioning holes. When the first sliding locking mechanism 10 rotates to the closed state, the second locking ball 331 is in one of the second positioning holes to keep the first sliding locking mechanism 10 stably in the closed state; when the first sliding locking mechanism 10 rotates to the unfolded state, the second locking ball 331 is in the other second positioning hole to keep the first sliding locking mechanism 10 stably in the unfolded state. When the first sliding locking mechanism 10 needs to be positioned in addition to the closed and unfolded states, it also needs to add a positioning position between these two positions (e.g., Figure 9 When the position is raised (in the middle), a corresponding number of positioning holes need to be added between the two second positioning holes.

[0101] The arrangement of the second positioning hole will be explained below, taking the example that the first sliding locking mechanism 10 only needs to switch between the closed state and the unfolded state.

[0102] Preferably, the outer peripheral wall of the shaft 311 is provided with two second through holes 3111. A second locking ball 331A and a second locking ball 331B are respectively disposed in the two second through holes 3111. Figure 14 As shown, the inner wall of the bushing 321 is provided with three second positioning holes, which are located on the same circumference and are respectively second positioning hole A 3212, second positioning hole B 3213 and second positioning hole C 3214. Second positioning hole C 3214 and second positioning hole A 3212 form a group and correspond to second locking ball 331A, which can be locked into both second positioning hole C 3214 and second positioning hole A 3212. Second positioning hole C 3214 and second positioning hole B 3213 form a group and correspond to second locking ball 331B, which can be locked into both second positioning hole C 3214 and second positioning hole B 3213. That is, the two groups share the second positioning hole C 3214, which reduces the number of second positioning holes and simplifies the structure. The distances between the second positioning hole C 3214 and the second positioning hole A 3212 and the second positioning hole B 3213 are the same. The central angle subtended by the arc between the second positioning hole C 3214 and the second positioning hole A 3212 is α, and the central angle subtended by the arc between the second positioning hole C 3214 and the second positioning hole B 3213 is β. α and β are equal and greater than 90°, preferably α and β are 120°. In this way, the rotation (flipping) angle of the first sliding locking mechanism 10 can be guaranteed.

[0103] When the second button 333 is pressed and is in a pressed state, the second reset member 332 is compressed and accumulates elastic potential energy. At the same time, the second push-resisting slope 3333 simultaneously releases the pressing of the two second locking balls 331 (the second locking ball 331A and the second locking ball 331B), and the two second locking balls 331 are respectively retracted into the two second through holes 3111. At this time, the rotating member 31 can drive the first sliding locking mechanism 10 to rotate (or flip) relative to the fixed member 32 and the second sliding locking mechanism 20. When the first sliding locking mechanism 10 rotates to be close to the second sliding locking mechanism 20 to be in a folded state, the second button 333 is released at this time, and the second button 333 is switched from the pressed state to the released state under the action of the second reset member 332. The second push-resisting slope 3333 simultaneously pushes the two second locking balls 331, and the second locking ball 331A is pressed against the hole bottom or the hole wall of the second positioning hole C 3214, and the second locking ball 331B is pressed against the hole bottom or the hole wall of the second positioning hole B 3213. In this way, the locking and fixing of the first sliding locking mechanism 10 in the folded state are realized, so that the first sliding locking mechanism 10 is stably kept in the state and cannot shake.

[0104] The rotating locking mechanism 30 of the embodiment of the present application can form a strong damping effect when the rotating member 31 rotates through the cooperation of the second locking ball 331, the second through hole 3111, the second positioning hole, and the button. The rotating locking mechanism 30 plays a role of gap elimination and constant damping, prevents the rotating member 31 from rotating too fast to affect the position adjustment of the first sliding locking mechanism 10, and can realize the fixation of a certain angle, which is reliable and greatly improves the use effect.

[0105] In some embodiments, as Figure 11 and Figure 12As shown, the fixing member 32 further comprises a fixing plate 322, which is provided with a fixing hole 3221, and two recesses 3222 are arranged on the hole wall of the fixing hole 3221. The outer peripheral wall of the shaft sleeve 321 is provided with two protrusions 3215, the shaft sleeve 321 is embedded in the fixing hole 3221, and the two protrusions 3215 are correspondingly clamped into the two recesses 3222, so as to fix the shaft sleeve 321 on the fixing plate 322. The rotating member 31 further comprises a first clamping plate 312 and a second clamping plate 313, which are clamped on opposite sides of the fixing plate 322, and the shaft rod 311 passes through the hole in the first clamping plate 312, the shaft sleeve 321 and the hole in the second clamping plate 313 in sequence, and is locked with the two clamping plates. In this way, the fixation of the shaft rod 311 and the two clamping plates is realized, and when the shaft rod 311 rotates, the two clamping plates can be driven to rotate synchronously, the first clamping plate 312 is fixed with the guide rail 11 of the first sliding locking mechanism 10, thereby driving the first sliding locking mechanism 10 to rotate.

[0106] Further, as shown in the drawings, Figure 12 The other end of the shaft rod 311 is a flat column and is provided with an external thread 3113, the second clamping plate 313 is provided with a waist-shaped hole 3131 matched with the other end of the shaft rod 311, and the other end of the shaft rod 311 is connected with an adjusting nut 314 after passing through the waist-shaped hole 3131. The tightness of the shaft rod 311 and the two clamping plates can be adjusted by the adjusting nut 314, thereby adjusting the tightness of the second button 333 and improving the use effect.

[0107] When the reversing support of the embodiment of the application is used to wear the night vision device on the helmet, the guide rail 11 of the second sliding locking mechanism 20 can be fixed on the helmet, and the guide rail 11 of the second sliding locking mechanism 20 can be formed by the guide rail 11 comprising the base 112 in the second embodiment, which can be attached to the helmet and conveniently and stably installed on the helmet. The night vision device is installed on the sliding seat 12 of the first sliding locking mechanism 10.

[0108] When the night vision device needs to be used, the second button 333 is pressed, and the first sliding locking mechanism 10 is adjusted to the unfolded state, at which time the guide rail 11 of the first sliding locking mechanism 10 is in a substantially horizontal state (see Figure 8), and is located in front of the user's head. At this time, if the sliding seat 12 of the second sliding locking mechanism 20 is slid along the guide rail 11 (the sliding direction is substantially the upper and lower direction), the rotating locking mechanism 30 and the first sliding locking mechanism 10 will be synchronously slid to adjust the up and down position of the night vision mirror fixed on the sliding seat 12 of the first sliding locking mechanism 10 relative to the user's eyes. If the sliding seat 12 of the first sliding locking mechanism 10 is slid along the guide rail 11, the front and back movement of the night vision mirror on it relative to the user's eyes will be driven, so that the up, down, front and back adjustment of the night vision instrument can be realized, so as to adjust the night vision instrument to a comfortable position for the user.

[0109] When the night vision instrument is not needed, the second button 333 is pressed, and the first sliding locking mechanism 10 is folded (see Figure 10 ) to the helmet to avoid the front of the user's head, and does not affect the normal activities of the user.

[0110] The locking mechanism gap of the flip bracket of the embodiment is small, which can form stable and reliable locking, avoid causing the night vision instrument to shake, and the adjustment operation is convenient and fast, and single-handed operation can be realized. At the same time, the flip bracket is light in weight, comfortable to wear, and has better use effect.

[0111] The above description is intended to be illustrative rather than restrictive, and those skilled in the art can make changes, modifications, replacements and variations to the above embodiments within the scope of the present disclosure. Moreover, the above examples (or one or more solutions thereof) can be used in combination with each other, and these embodiments can be combined with each other in various combinations or arrangements.
