And when need not to shoot, can hang from rapping bar body through the mutual joint of coupling mechanism 40 and installation mechanism 20 on external mounting structure, and need not to dismantle shooting equipment from rapping bar to bring very big facility for the user.

It will be appreciated that in other embodiments, the quick release device 100 may not be coupled to the selfie stick body, but may be used only to mount the photographing apparatus to an external mounting structure.

As shown in fig. 3 to 5, the connection mechanism 40 includes a main shaft body 41 and a shaft housing 42 sleeved outside the main shaft body 41, the main shaft body 41 is detachably connected with the self-timer stick body, and the shaft housing 42 is detachably connected with the photographing apparatus. The spindle body 41 is rotatable relative to the mounting mechanism 20 to mechanically couple or decouple the mounting mechanism 20. When the spindle body 41 rotates relative to the mounting mechanism 20, the mounting mechanism 20 restrains the axle housing 42 to prevent the axle housing 42 from following the rotation of the spindle body 41.

Thus, the main shaft 41 can be driven to rotate relative to the mounting mechanism 20 by rotating the selfie stick body, so that the selfie stick body can be dismounted. In the rotation process, the mounting mechanism 20 is used for preventing the axle housing 42 from rotating along with the main shaft body 41, so that the photographing equipment connected to the axle housing 42 can be prevented from rotating along with the main shaft body 41, and collision and falling caused by rotation of the photographing equipment can be prevented, and the practicability of the quick-release device 100 is improved.

Referring to fig. 3, 4 and 7, the mounting mechanism 20 includes a mounting bracket 21, the mounting bracket 21 includes a bracket main body 212 and two mounting arms 214, the two mounting arms 214 are respectively connected to opposite ends of the bracket main body 212, the bracket main body 212 and the two mounting arms 214 together define a connecting slot 21a, and surfaces of the bracket main body 212 and the two mounting arms 214 form slot walls of the connecting slot 21 a. The side of the bracket body 212 facing away from the connecting slot 21a is coupled with the hitching mechanism 60, and the connecting mechanism 40 can extend into the connecting slot 21a to mechanically couple with the mounting mechanism 20.

It will be appreciated that the shape of the axle housing 42 is adapted to the shape of the connecting groove 21a, and in some embodiments, the cross section of the connecting groove 21a may be "U" shaped or semi-circular, the axle housing 42 has a substantially solid structure, and the outer circumferential surface of the axle housing 42 may be fitted to the groove wall of the connecting groove 21a to be in mating abutment with the connecting groove 21 a.

In order to restrict the rotation of the axle housing 42 relative to the mounting mechanism 20, the mounting bracket 21 is provided with a first rotation stopper, the main axle body 41 is provided with a second rotation stopper, and the first rotation stopper and the second rotation stopper are mutually engaged to prevent the axle housing 42 from following the main axle body 41 to rotate. Specifically, one of the first rotation stopping portion and the second rotation stopping portion is a rotation stopping groove, the other one of the first rotation stopping portion and the second rotation stopping portion is a rotation stopping protrusion, and the rotation stopping protrusion is limited in the rotation stopping groove.

As a preferred embodiment, an inward concave rotation stopping groove 2121 is formed on the groove wall of the connecting groove 21a, and a rotation stopping protrusion 4212 is respectively protruded on opposite sides of the shaft housing 42 in a radial direction, and the shape of any rotation stopping protrusion 4212 is matched with the shape of the rotation stopping groove 2121. In particular, in one embodiment, a rotation stop groove 2121 is formed in the bracket body 212. Thus, when the main shaft body 41 is mechanically coupled to the mounting mechanism 20, one of the rotation stopping protrusions 4212 is embedded in the rotation stopping groove 2121, and the shaft housing 42 cannot rotate relative to the mounting mechanism 20 under the blocking of the groove wall of the rotation stopping groove 2121. It will be appreciated that in other embodiments, the rotation stopping grooves may be formed in the axle housing 42, and the rotation stopping protrusions may be formed in the groove walls of the connecting grooves 21a, which also serve to prevent the axle housing 42 from rotating.

Specifically, in one embodiment, the axle housing 42 includes a main housing 421 and an adapter 423. The main housing 421 has a cylindrical structure and has a housing top wall and a housing side wall extending from an edge of the housing top wall toward the same side, wherein the housing side wall circumferentially surrounds the housing top wall, thereby forming an open-ended accommodation cavity for accommodating the shaft core 414, and the rotation stop protrusion 4212 on the shaft housing 42 is formed on an outer surface of the housing side wall. The adapter 423 is protruding to locate the surface of casing roof for can dismantle with shooting equipment and be connected. In particular, in one embodiment, the adapter 423 is a screw extending along an axial direction of the main housing 421 to be screwed with the photographing apparatus.

The shaft core 414 has a solid structure, and includes a first core 4141 and a second core 4143 that are connected to each other in the axial direction, and an outer circumferential surface of the first core 4141 is provided with an external thread. The shaft core shell 412 has a circular tube-shaped structure with two open ends, and an internal thread is formed in the shaft core shell 412. The first core 4141 of the shaft core 414 is inserted into the shaft core housing 412 to be screwed with the shaft core housing 412, and the first core 4141 of the shaft core 414 protrudes out of the shaft core housing 412.

The connection mechanism 40 further includes a bearing 43 and a sleeve 44. The bearing 43 is sleeved on the second core 4143 of the shaft core 414 and is matched with the shaft housing 42, one end, far away from the first core 4141, of the second core 4143 is further provided with a baffle part 4145, the outer diameter of the baffle part 4145 is larger than that of the second core 4143 and is matched with the inner diameter of the shaft housing 42, the baffle part 4145 seals the opening end of the shaft housing 42, and therefore the bearing 43 is prevented from being exposed to the external space, and the bearing 43 is prevented from being blocked due to foreign matters. The sleeve 44 has a hollow annular structure, and the sleeve 44 is sleeved outside one end of the shaft core housing 412 protruding from the first core 4141 and abuts against the housing top wall of the main housing 421 of the shaft housing 42 in the axial direction.

In this way, the spindle body 41 and the shaft sleeve 44 of the bearing 43 can smoothly rotate relatively, and the shaft sleeve 44 at the top and the bearing 43 at the bottom provide double-end support for the shaft sleeve 44 and the spindle body 41, so that the rotation stability of the spindle body 41 is effectively improved, and the reliability of the connecting mechanism 40 is improved. Moreover, since the axle housing 42 is integrally designed, the function of connecting the photographing apparatus is integrated, so that it has high structural strength, and the stability of the connection mechanism 40 is improved.

As shown in fig. 3, 4 and 7, in order to mechanically couple or decouple the main shaft body 41 to or from the mounting mechanism 20, the shaft housing 42 is further provided with a positioning portion, and the mounting mechanism 20 further includes an elastic positioning assembly 23 provided on the mounting bracket 21. When the connection mechanism 40 is fitted and abutted with the connection groove 21a of the mounting bracket 21, the elastic positioning member 23 connects the connection mechanism 40 to the mounting mechanism 20 by mechanically coupling with the positioning portion, or the elastic positioning member 23 separates the connection mechanism 40 from the mounting mechanism 20 by releasing the mechanical coupling with the positioning portion.

Specifically, the mounting arm 214 of the mounting bracket 21 has a mounting groove 214a in communication with the connecting groove 21a, and the elastic positioning assembly 23 is disposed in the mounting groove 214a and includes a stopper 232 slidably disposed in the mounting groove 214 a. When the connection mechanism 40 is in fit abutment with the connection groove 21a, one end of the limiting member 232 extends into the connection groove 21a from the mounting groove 214a, and is mechanically coupled with the positioning portion to connect the connection mechanism 40 with the mounting mechanism 20.

In some embodiments, stop 232 includes a connection block 2321, a first stop post 2123, and a second stop post 2325. First and second stopper posts 2123 and 2325 are respectively connected to the same side of connection block 2321 and are disposed at intervals. The positioning portion is a positioning hole 4214 formed in a housing side wall of the main housing 421 of the shaft housing 42, and the main housing 421 of the shaft housing 42 further has a receiving groove 4216 provided at an interval from the positioning hole 4214 in the axial direction. When the connection mechanism 40 is in fit abutment with the connection groove 21a, one end of the first limiting post 2123 extends into the accommodating groove 4216 from the mounting groove 214a, and one end of the second limiting post 2325 extends into the positioning hole 4214 from the mounting groove 214a, so that the connection mechanism 40 is fixed in the connection groove 21a, and the connection mechanism 40 and the mounting mechanism 20 are mutually connected.

Further, the resilient positioning assembly 23 further includes a fixed plate 234, a guide post 236, and a resilient member 238. The mounting groove 214a penetrates the mounting arm 214, the fixing plate 234 is fixedly connected to an opening of one end of the mounting groove 214a far away from the connecting groove 21a through a fastener, one end of the guide post 236 is fixed to one side of the fixing plate 234 facing the connecting groove 21a, and the other end of the guide post 236 extends toward the connecting groove 21 a. One end of the elastic member 238 is connected to the fixing plate 234, and the other end of the elastic member 238 is connected to the connection block 2321 of the stopper 232. The connection block 2321 is further provided with a guide hole, and one end of the guide post 236 away from the fixing plate 234 is inserted into the guide hole. In this manner, the connection block 2321 may slide along the guide posts 236, thereby stabilizing the sliding of the connection block 2321 within the mounting slot 214 a. In some embodiments, the elastic member 238 is a spring, and the spring is wound around the connection block 2321.

As a preferred embodiment, the elastic positioning components 23 are two groups, the two groups of elastic positioning components 23 are respectively and oppositely arranged on the two mounting arms 214 of the mounting bracket 21, and correspondingly, the opposite sides of the axle housing 42 in a radial direction are provided with positioning holes 4214 and accommodating grooves 4216 corresponding to the two groups of elastic positioning components 23, so that the connection stability of the connecting mechanism 40 and the mounting mechanism 20 is improved.

In some embodiments, the receiving groove 4216 is an elongated groove extending along the circumferential direction of the shaft housing 42, the outer circumferential surface of the shaft core housing 412 of the main shaft body 41 is embedded with the ejection member 416, and one end of the ejection member 416 extends into the receiving groove 4216 of the shaft housing 42, and in the circumferential direction of the shaft core housing 412, the length of the ejection member 416 is smaller than the length of the receiving groove 4216. When the spindle body 41 rotates relative to the axle housing 42, the ejector 416 slides in the receiving groove 4216 along with the spindle body 41, and the ejector 416 can move out of the receiving groove 4216 by pushing the first limit post 2123 to move radially along the axle housing 42 during sliding. Because the first limiting post 2123 and the second limiting post 2325 are fixedly connected through the connecting block 2321, the movement of the first limiting post 2123 can drive the second limiting post 2325 to move along the radial direction of the shaft housing 42 and separate from the positioning hole 4214, so that the separation between the connecting mechanism 40 and the mounting mechanism 20 is realized, and a user only needs to hold the selfie stick to move the connecting mechanism 40 out of the connecting groove 21 a.

Specifically, the ejector 416 has an arcuate surface provided away from the main shaft body 41, and in the circumferential direction of the shaft housing 42, the arcuate surface extends obliquely from the notch of the receiving groove 4216 toward the groove bottom of the receiving groove 4216. The main shaft body 41 has an initial position with respect to the shaft housing 42, when the main shaft body 41 is in the initial position with respect to the shaft housing 42, the ejector 416 is located at one end of the receiving groove 4216 in the length direction, and one side of the arcuate surface near the notch of the receiving groove 4216 is flush with the outer circumferential surface of the shaft housing 42. During the process of placing the connection mechanism 40 in the connection groove 21a, the end of the first stopper 2123 facing the shaft housing 42 slides from the outer circumferential surface of the shaft housing 42 into the receiving groove 4216, which is provided with the ejector 416. When the axle housing 42 is abutted against the inner wall of the connecting slot 21a, the first limiting post 2123 at least partially extends into the end of the accommodating slot 4216 provided with the ejection member 416 to be abutted against the arc surface, and the second limiting post 2325 also at least partially extends into the positioning hole 4214. When the main shaft body 41 is rotated until the end of the arc surface flush with the outer circumferential surface of the shaft housing 42 abuts against the second limiting post 2325, the limiting piece 232 is completely separated from the accommodating groove 4216 and the positioning hole 4214.

In some embodiments, the outer circumferential surface of the shaft housing 42 is embedded with a first magnetic member 45, and the outer circumferential surface of the shaft core housing 412 of the main shaft body 41 is embedded with a second magnetic member 418 that can attract the first magnetic member 45. In the case where the main shaft body 41 is not subjected to an external force, the main shaft body 41 and the shaft housing 42 have a reset state under the attractive force between the first magnetic member 45 and the second magnetic member 418, and in the reset state, the ejector member 416 is located at one end of the receiving groove 4216 without interfering with the first stopper post 2123 protruding into the receiving groove 4216. Thus, each time the user removes the connecting mechanism 40 from the mounting mechanism 20, the main shaft 41 can rotate relative to the shaft housing 42 to return to the reset state under the attraction of the first magnetic member 45 and the second magnetic member 418, so that the next mounting is facilitated.

As a preferred embodiment, two first magnetic members 45 are embedded on the outer circumferential surface of the shaft housing 42, and the two magnetic members are respectively located at two opposite sides of the shaft housing 42 in a radial direction and are respectively located between the two receiving grooves 4216. Correspondingly, two second magnetic pieces 418 are embedded on the outer circular surface of the shaft core shell 412, the two second magnetic pieces 418 are respectively located at two opposite sides of the shaft core shell 412 in the radial direction and are respectively located between the two ejection pieces 416, and the two second magnetic pieces 418 are respectively arranged in one-to-one correspondence with the two first magnetic pieces 45. By providing the two first magnetic members 45 and the second magnetic member 418, the reaction speed of the main shaft body 41 when returning to the reset state can be increased, and the stability of the main shaft body 41 when being in the reset state relative to the shaft housing 42 can be increased.

Further, in some embodiments, the first magnetic member 45 is embedded in the rotation stopping protrusion 4212 of the axle housing 42, and the rotation stopping groove of the mounting bracket 21 is embedded with the third magnetic member 25, and the third magnetic member 25 may be attracted to the first magnetic member 45. In this way, the insertion of the connection mechanism 40 can be guided during the insertion of the connection mechanism 40 into the connection groove 21a, so that an error in the angle of the connection mechanism 40 into the connection groove 21a is avoided, and the shaft housing 42 is further prevented from rotating relative to the mounting mechanism 20 during the detachment of the selfie stick body.

In some embodiments, the connection mechanism 40 further includes a torsion spring 46, where the torsion spring 46 is disposed between the axle housing 42 and the main axle body 41, one end of the torsion spring 46 is fixed to the axle housing 42, and the other end of the torsion spring 46 is fixed to the axle core housing 412 and located on a side of the bearing 43 facing away from the barrier 4145. Specifically, the axle housing 42 and the axle core housing 412 are each provided with a fixing groove, and two ends of the torsion spring 46 are respectively inserted into the two fixing grooves.

When the main shaft body 41 is in the reset state, the torsion spring 46 is in a stretched state to apply a pretightening force between the main shaft body 41 and the shaft housing 42. When the main shaft body 41 needs to rotate from the initial position relative to the shaft housing 42, because the elastic force exerted by the torsion spring 46 is larger and larger in the process of continuously rotating, and the magnetic attraction between the first magnetic piece 45 and the second magnetic piece 418 is continuously reduced, the magnetic attraction between the first magnetic piece 45 and the second magnetic piece 418 and the elastic force exerted by the torsion spring 46 are overlapped to form complementation, and the external force exerted by a user in the process of rotating the main shaft body 41 is approximately uniform, so that the experience of the user in rotating the selfie stick is improved, and the rotation is smoother.

In some embodiments, the adapter 423 of the axle housing 42 is coupled with a nut 47, and an angle of a photographing apparatus coupled to the axle housing 42 can be adjusted by rotating the nut 47.

Referring to fig. 3 and 4, the working principle of the quick release device 100 is as follows:

one end of the selfie stick body is connected to the connecting mechanism 40, and the mounting mechanism 20 is mounted on an external mounting structure through the hanging mechanism 60. When the self-timer stick body needs to be hung, the connecting mechanism 40 connected to the self-timer stick body can be stretched into the connecting groove 21a of the mounting bracket 21 of the connecting mechanism 40, under the guiding effect of the mutual attraction of the first magnetic piece 45 and the third magnetic piece 25, the rotation stopping protrusion 4212 on the shaft housing 42 is limited in the rotation stopping groove 2121 on the mounting bracket 21, meanwhile, the first limiting post 2123 of the limiting piece 232 of the elastic positioning assembly 23 stretches into the accommodating groove 4216, and the second limiting post 2325 also stretches into the positioning hole 4214, so that the mechanical coupling between the connecting mechanism 40 and the mounting mechanism 20 is realized.

When the self-timer stick body is detached, the user can rotate the self-timer stick body to drive the main shaft body 41 to rotate relative to the mounting bracket 21, and meanwhile, under the limiting effect of the mounting bracket 21, the shaft housing 42 is kept stationary relative to the mounting bracket 21 to prevent the photographing apparatus from rotating in the process. The rotation of the main shaft 41 rotates the ejector member 416 to the other end of the accommodating groove 4216, and the first limiting post 2123 is separated from the accommodating groove 4216 under the supporting of the ejector member 416, so as to drive the second limiting post 2325 to synchronously separate from the positioning hole 4214, so that a user can detach the self-timer stick body from the mounting mechanism 20.

Above-mentioned quick detach device 100 and from rapping bar, when rotatory dismouting is from rapping bar body, because axle housing 42 is spacing unable the rotation relative coupling mechanism 40, consequently connect in the shooting equipment of axle housing 42 can not follow from rapping bar body synchronous rotation, consequently can avoid following from rapping bar body rotation and causing the bump because shooting equipment prevents effectively that shooting equipment from droing. Moreover, the axle housing 42 is integrally designed, which improves the strength of the product and enhances the stability and reliability of the overall structure of the quick release device 100, as compared to a structure in which the upper and lower axle housings are spliced with each other.
