In view of this, referring to fig. 1 to 8, in an embodiment of the present utility model, a position-switching locking base structure 100 is provided for installing a fixing member 200, where the position-switching locking base structure 100 includes a base 110, a locking portion 120, a first limiting portion 130, and a first elastic member 140.

Referring to fig. 1-6, base 110 is adapted to receive a fastener 200. The fixing member 200 may be any device suitable for being mounted and fixed on a base, including but not limited to various photographing devices and quick release plates. In some embodiments, the base 110 may include a seating portion for seating the fixture 200, and the seating portion may define a seating cavity. The base 110 may also include structures that enable connection with other photographic equipment, for example, the base 110 may also include screws, screw holes, snaps, or slide slots adapted to connect with other bases or tripods.

Referring to fig. 1 to 6, the locking part 120 is coupled to the base 110. In various embodiments, the locking portion 120 may be directly connected to the base 110, or may be indirectly connected to the base 110. The locking portion 120 is movable between a first position and a second position relative to the base 110. The locking portion 120 is adapted to be driven by the fixing member 200 to move to the second position during assembly of the fixing member 200 when in the first position, and the locking portion 120 is adapted to abut against the fixing member 100 when in the second position. That is, the fixing member 200 is adapted to be assembled to the position switching locking base structure 100 when the locking portion 120 is in the first position. When the locking portion 120 is in the second position, the locking portion 120 is adapted to abut against the fixing member 200. When the locking portion 120 is located at the first position, the state may correspond to a state suitable for assembling the fixing member 200 to the position switching locking base structure 100, or the first state may correspond to a state in which the position switching locking base structure 100 and the fixing member 200 are detachably connected (loosely connected); accordingly, when the locking portion 120 is located at the second position, the second state may correspond to the position switching locking base structure 100 abutting against the fixing member 200 (the position switching locking base structure 100 clamps the fixing member 200), and the fixing member 200 is in a close-fit connection state with respect to the position switching locking base structure 100.

Referring to fig. 7 to 8, the first stopper 130 is connected to the base 110. In different embodiments, the first limiting portion 130 may directly contact the connection base 110, or may indirectly connect to the base 110. The first limiting portion 130 has a third position and a fourth position with respect to the locking portion 120. When the first limiting portion 130 is located at the third position, the locking portion 120 can switch between the first position and the second position. That is, the first limiting portion 130 does not limit the position switching of the locking portion 120 at this time. It is understood that when the locking portion 120 is in the second position, the first limiting portion 130 can move to the fourth position. That is, when the locking portion 120 is located at the position of the locking fixing member, the first limiting portion 130 can further move to the position of locking the locking portion 120, and therefore, when the first limiting portion 130 is located at the fourth position, the first limiting portion 130 can abut against the locking portion 120 to limit the locking portion 120 to move to the first position. For the state of the first limiting portion 130 at this time, in some embodiments, the first limiting portion 130 may abut the locking portion 120 at this time; in other embodiments, the first limiting portion 130 may not contact the locking portion 120 at this time, and the first limiting portion 130 may be used to limit the displacement motion of the locking portion 120 from the second position to the first position at this time.

Referring to fig. 3 to 6, the first elastic member 140 connects the base 110 and the locking portion 120. Thus, in some embodiments, one end of the first elastic member 140 may be connected to the base 110, and the other end may be connected to the locking portion 120, so that the locking portion 120 may be indirectly connected to the base 110. The first elastic member 140 is configured to generate an elastic force that drives the locking part 120 to move from the second position to the first position. Specifically, when the locking portion 120 is located at the second position, the first elastic member 140 may be compressed, and when the locking portion 120 needs to be switched between the positions, the first elastic member 140 may release the elastic force, and thus the first elastic member 140 may drive the locking portion 120 to move to the first position. It should be noted that, in different embodiments, the first elastic member 140 may be a spring, a torsion spring, rubber, silicone, or the like.

According to the combination of the above embodiments, it can be seen that in some embodiments, the position switching locking base structure 100 of the present application includes a base 110 for placing a fixing member 200, a locking portion 120 capable of switching positions to lock the fixing member 200, a first limiting portion 130 capable of limiting the movement of the locking portion 120, and a first elastic member 140 capable of driving the locking portion 120 from the second position to the first position. Thus, referring to fig. 3-6, in some embodiments, the step of attaching the securing member 200 to the position switch locking base structure 100 may be: in the initial state, the first elastic member 140 is in a relaxed state, so that the locking portion 120 is in the first position, and at this time, the first limiting portion 130 is in the third position, when the fixing member 200 needs to be installed, the fixing member 200 is placed into the placement cavity of the base 110, and the locking portion 120 is pressed while the fixing member 200 is installed, thereby driving the locking portion 120 to move from the first position to the second position and compressing the first elastic member 140, and simultaneously, the first limiting portion 130 moves to the fourth position, and then the first limiting portion 130 can abut against the locking portion 120, so as to limit the locking portion 120 to move from the second position to the first position. As can be seen from the above description of the steps, the locking portion 120 can be simultaneously driven to switch from the first position to the second position by the action of the locking base structure 100 when the fixing member 200 is installed, that is, the fixing member 200 can drive the locking portion 120 to move to a position capable of locking the fixing member 200, and along with the movement of the locking portion 120, the first limiting portion 130 can correspondingly move to different positions to abut against the locking portion 120 or enable the locking portion 120 to move freely. Therefore, the position switching locking base structure 100 of the present application can drive the locking part 120 to move to the position of locking the fixing member 200 through the loading action of the fixing member 200, and simultaneously the first limiting part 130 can move to the position capable of limiting the movement of the locking part 120, so that the position switching locking base structure 100 makes the installation process of the fixing member 200 more convenient and improves the installation stability.

To switch the locking portion 120 between the first position and the second position, referring to fig. 3-6, in some embodiments, the locking portion 120 may be configured to be rotatable about the rotation axis L to switch the position between the first position and the second position. That is, the first position and the second position are different positions reached by the locking portion 120 rotating around the rotation axis L. The rotation axis L may be located in the self portion of the locking portion 120 or may be located outside the locking portion 120. In various embodiments, the locking portion 120 may be freely rotatable about the rotation axis L, or may be driven to rotate about the rotation axis L. For convenience of description, the following description will be given by taking an embodiment in which the locking portion 120 is rotated about the rotation axis L to perform position switching, and different embodiments may be combined with each other between different technical solutions. Referring to fig. 3, in some embodiments, when the locking portion 120 is in the first position, the fixing member 200 is connected to the base 110 and can abut against one end of the locking portion 120, so that the fixing member 200 can drive the locking portion 120 to move to the second position.

In response to the rotational arrangement of the above-described embodiment, some specific arrangements of the locking portion 120 will be described below, referring to the drawings, defining a second direction Y perpendicular to the rotational axis L for convenience of description, the base 110 is configured to be suitable for assembling the fixing member 200 along the second direction Y. The locking part 120 is configured to be capable of rotating around a rotation axis L to perform position switching between a first position and a second position, the base 110 has a first wall 114 and a second wall 115, the first wall 114 is used for defining a first cavity 116, the second wall 115 is used for defining a second cavity 117, the first wall 114 has a first opening 1141 communicated with the first cavity 116, the second wall 115 has a second opening 1151 communicated with the second cavity 117, the locking part 120 includes a first portion 122 and a second portion 123, the first portion 122 has a third wall 1221, the second portion 123 has a fourth wall 1231, an included angle between the third wall 1221 and the fourth wall 1231 is an acute angle, and the third wall 1221 and the fourth wall 1231 are adapted to abut against an end of the fixing member 200 perpendicular to the rotation axis L;

When the locking portion 120 is in the first position, the first portion 122 extends out of the first cavity 116 from the first opening 1141, the second portion 123 is located inside the second cavity 117, the third wall 1221 is adapted to contact the first contact surface 210 of the fixing member 200, so that the first portion 122 can rotate during the assembly of the fixing member 200 to extend into the first cavity 116 from the first opening 1141 during the switching of the locking portion 120 from the first position to the second position, and the second portion 123 is adapted to rotate during the assembly of the fixing member 200 and extend out of the second cavity 117 from the second opening 1151;

When the locking portion 120 is at the second position, the third wall surface 1221 contacts the first contact surface 210 of the fixing member 200, the fourth wall surface 1231 is adapted to abut the second contact surface 220 of the fixing member 200, and along the second direction Y, the third wall surface 1221 is located on a side of the first contact surface 210 near the first wall surface 114, and the fourth wall surface 1231 is located on a side of the second contact surface 220 far from the first wall surface 114.

The first limiting portion 130 may also have different positions corresponding to the first position and the second position of the locking portion 120, so as to correspond to whether the first limiting portion has a limiting function state. In particular, referring to fig. 7-8, in some embodiments, the first stop 130 may have a third position and a fourth position relative to the locking portion 120. The first elastic member 140 is a first spring. Based on the above-described rotational arrangement of the locking portion 120, in some embodiments, the first spring may have one end connected to the base 110 and the other end connected to an end of the locking portion 120. The locking portion 120 is located at the first position, and the first limiting portion 130 is located at the third position, the first spring may be configured to release the elastic force. That is, the first spring may be in a relaxed state (no additional external force is applied to the first spring) at this time to maintain the locking part 120 in the first position. When the locking portion 120 is at the second position and the first limiting portion 130 is at the fourth position, along the radial direction of the rotation axis L, one end of the locking portion 120 away from the rotation axis L compresses the first spring, and the other end away from the rotation axis L can abut against the first limiting portion 130. That is, at this time, one end of the locking portion 120 in the rotation direction may compress the first spring by the abutment force of the fixing member 200, and the other end in the same radial direction may be disposed opposite to the first limiting portion 130, so that the first limiting portion 130 can limit the movement of the locking portion 120 to the first position.

Referring to fig. 7-8, in some embodiments, the base 110 may define an interior cavity 111. It should be noted that, the cavity 111 may be a closed cavity 111 located in the base 110; alternatively, the opening cavity 111 may be provided with a notch and connected to the outside of the base 110, and the boundary of the cavity 111 at the notch is determined by the opening edge of the notch. The base 110 may have a through hole 112 communicating with the cavity 111. Based on this, to facilitate the switching of the first limiting portion 130 between the third position and the fourth position, in some embodiments, the first limiting portion 130 may be disposed through the through hole 112 along the first direction X, so that the first limiting portion 130 is at least partially located in the inner cavity 111. The first limiting portion 130 is slidably connected to the base 110, and can switch between a third position and a fourth position along the first direction X. For the sliding connection form described above, in some embodiments, the first limiting portion 130 may form a sliding connection between the first limiting portion 130 and the base 110 only by penetrating the inner cavity 111 through the through hole 112; in other embodiments, the inner wall surface defining the inner cavity 111 may further be provided with a sliding groove, and the first limiting portion 130 may extend into the sliding groove to form a sliding connection with the sliding groove to form a sliding connection between the first limiting portion 130 and the base 110.

For the specific structure of the locking portion 120 and the first limiting portion 130, referring to fig. 7 to 8, in some embodiments, the locking portion 120 may include a snap protrusion 121. The locking protrusion 121 may have a protrusion structure fixed to the locking portion 120 and may be movable along with the movement of the locking portion 120. The first stopper 130 may have a fifth wall surface 131 facing the catching protrusion 121 in a second direction Y perpendicular to the first direction X. It can be understood that, the first direction X is a direction in which the first limiting portion 130 moves for switching positions, and the engaging protrusion 121 may be located on one side of the first limiting portion 130 along the second direction Y to enable the locking portion 120 to switch positions. The fifth wall surface 131 may define a limiting protrusion 132 and a limiting groove 133 disposed opposite to each other along the first direction X, that is, the fifth wall surface 131 may extend along the first direction X, and simultaneously define a protrusion structure and a groove structure at the first limiting portion 130. Based on the above-described arrangement of the embodiments, in some embodiments, referring to fig. 3 and 7, when the locking portion 120 is in the first position, the first limiting portion 130 is in the third position, and the clamping protrusion 121 is located in the limiting groove 133. That is, the locking portion 120 may be located relatively close to the first limiting portion 130 along the second direction Y at this time, so that the engaging protrusion 121 can be located in the limiting groove 133 at this time. Further, at this time, the limiting groove 133 may abut against the clamping protrusion 121 along the first direction X, so as to limit the movement of the first limiting portion 130 along the first direction X. Referring to fig. 5 and 8, when the locking portion 120 is in the second position, the first limiting portion 130 is in the fourth position, and the limiting protrusion 132 can abut against the clamping protrusion 121 to limit the movement of the locking portion 120 to the first position. That is, at this time, the engaging protrusion 121 of the locking portion 120 is opposite to the limiting protrusion 132 along the second direction Y, and the abutting action of the two protrusions can limit the movement of the locking portion 120.

For the above-described arrangement of the limit projection 132 and the limit groove 133. In some embodiments, in the first direction X, the limit protrusion 132 may have a sidewall 1321 extending in the second direction Y. Based on the description of the above embodiment, the second direction Y may be a direction in which the fifth wall surface 131 is opposite to the engaging protrusion 121. The side wall 1321 may be used to define the limit groove 133. It will be appreciated that the side wall 1321 may also define the limit groove 133 while being part of the limit projection 132. The above arrangement can enable the limiting protrusion 132 and the limiting groove 133 to be adjacently arranged, so that the position switching of the first limiting portion 130 is convenient, that is, the first limiting portion 130 reciprocates along the first direction X, so that the limiting protrusion 132 is opposite to the clamping protrusion 121, or the limiting groove 133 is opposite to the clamping protrusion 121; meanwhile, the driving stroke of the switching position of the first limiting part 130 is shorter, and the manufacturing cost of the first limiting part 130 is saved.

In order to conveniently drive the first limiting portion 130 for position switching, referring to fig. 7 to 8, in some embodiments, the position switching locking base structure 100 may further include a second elastic member 150. The second elastic member 150 may be configured to generate an elastic force that drives the first stopper 130 to move from the third position to the fourth position. Based on the above-mentioned functions, the kinds and arrangement of the second elastic member 150 can refer to the above-mentioned first elastic member 140, and will not be described herein.

Further, the through hole 112 is also configured based on the above embodiment, that is, the base 110 defines the inner cavity 111, the base 110 has the through hole 112 communicating with the inner cavity 111, and the first limiting portion 130 is disposed through the through hole 112 along the first direction X. To facilitate the second elastic member 150 to exert its elastic driving force, in some embodiments, the first stopper 130 may include a first section and a second section that are oppositely disposed along the first direction X. The first section may be located within the lumen 111 and the second section may be located outside the lumen 111. It is understood that the first limiting portion 130 may be partially penetrated into the inner cavity 111 by the through hole 112, and partially positioned outside the inner cavity 111. The above arrangement may facilitate a user pushing and pulling the second section to drive the first drive section in the first direction X.

In particular, referring to fig. 7-8, in some embodiments, the second resilient member 150 may be a second spring. Therefore, the second spring may be sleeved on the first limiting portion 130, and one end of the second spring may be connected to the first limiting portion 130, and the other end may be connected to the base 110 along the first direction X. Based on the above, in some embodiments, when the first limiting portion 130 is located at the third position, the second spring may be compressed, and the locking portion 120 abuts against the first limiting portion 130 to limit the movement of the first limiting portion 130 to the fourth position. In combination with the above embodiment, the clamping protrusion 121 may be located in the limiting groove 133, so that the wall surface of the groove body of the limiting groove 133 can abut against the locking portion 120 to limit the elastic force released by the second spring. When the fixing member 200 needs to be installed, the locking portion 120 is driven to switch positions, and at this time, in the process of moving the locking portion 120 from the first position to the second position, the locking portion 120 can be separated from the first limiting portion 130, so that the second spring releases the elastic force and drives the first limiting portion 130 to move to the fourth position. In combination with the above embodiment, the snap projection 121 can be moved to a position where it is separated from the limit groove 133 in the process, whereby the second spring can release the elastic force.

To further lock the securing member 200, and secure the installation, referring to fig. 3-6, in some embodiments, the position-switching locking base structure 100 may further include a second limiting portion 160. Similar to the first stop 130 described above, the second stop 160 can also be used to limit movement of the locking portion 120, and in particular, in some embodiments, the second stop 160 can be coupled to the base 110, and the second stop 160 can have a fifth position and a sixth position relative to the locking portion 120.

When the second limiting portion 160 is located at the fifth position, the locking portion 120 can be switched between the first position and the second position. That is, the second limiting portion 160 does not limit the position switching of the locking portion 120 at this time. When the second limiting portion 160 is located at the sixth position, along the radial direction of the rotation axis L, one end of the locking portion 120 away from the rotation axis L is connected to the first elastic member 140, and the other end of the locking portion away from the rotation axis L can abut against the second limiting portion 160. Similarly, for the state of the second limiting portion 160 at this time, in some embodiments, the second limiting portion 160 may abut against the locking portion 120 at this time; in other embodiments, the second limiting portion 160 may not contact the locking portion 120 at this time, and the second limiting portion 160 may be used to limit the displacement motion of the locking portion 120 from the second position to the first position at this time.

In combination with the above-described embodiment, when the locking portion 120 is switched between the first position and the second position by rotating about the rotation axis L, referring to fig. 3 to 6, in some embodiments, the first elastic member 140 may be located at one end of the rotation axis L, and the first limiting portion 130 and the second limiting portion 160 may be located at the other end along the radial direction, so that the abutting limiting effect of the first limiting portion 130 and the second limiting portion 160 may be better through the above-described two-end arrangement. According to different usage requirements, in other embodiments, the first elastic member 140, the first limiting portion 130, and the second limiting portion 160 may be disposed on any side of the rotation axis L, and may have different relative positions, which will not be described herein.

For the specific arrangement of the second limiting portion 160 described above, referring to fig. 3-6, in some embodiments, the second limiting portion 160 may include an external thread 161, and the external thread 161 may cooperate with the threaded hole 113 to fix the relative position of the second limiting portion 160 and the base 110 when the second limiting portion 160 is located at the sixth position. Therefore, the external thread 161 moves relative to the threaded hole 113 in a screwing manner, so that the second limiting part 160 is switched between the fifth position and the sixth position, and the structure ensures that the second limiting part 160 cannot be switched when not receiving a screwing force, thereby improving the position stability of the second limiting part 160. May pass through. More specifically, in some embodiments, the second limiting portion 160 may be disposed through the threaded hole 113, the base 110 may define the inner cavity 111, and the threaded hole 113 may be connected to the inner cavity 111, so that the portion of the second limiting portion 160 and the locking portion 120 for abutting is located in the inner cavity 111.

In combination with the above-described embodiment, when the locking portion 120 is switched between the first position and the second position by rotating about the rotation axis L, the screw hole 113 may extend in the radial direction of the rotation axis L, and the second limiting portion 160 may be located at an end of the rotation axis L away from the first elastic member 140 in the radial direction of the rotation axis L.

In order to make the mounting of the fixing member 200 more stable when the position switching locking base structure 100 is in the second state. The displacement of the fixing member 200 in the direction away from the position switching locking base structure 100 may be further limited, referring to fig. 1-2, in some embodiments, the base 110 may be provided with a slope, the slope forms an angle with the wall of the fixing member 200 contacting the base 110, and the specific angle setting may be adapted to the fixing member 200 with different specifications. During movement of the fixing member 200 in a direction away from the position switching locking base structure 100, the inclined surface can abut against the fixing member 200 and limit displacement of the fixing member 200. In addition, the displacement of the fixing member 200 on the wall surface in contact with the position switching locking base structure 100 may be further restricted, and referring to fig. 2, the base 110 may be further provided with a drop-off preventing screw in some embodiments. In some embodiments, the anti-falling screw may be disposed on a wall surface where the fixing member 200 contacts the position switching locking base structure 100, and the fixing member 200 may contact the anti-falling screw during the moving process of the fixing member 200 on the wall surface of the base 110, so that the anti-falling screw may prevent the fixing member 200 from falling off from the base 110.

For example, one specific way to mount and dismount the fixing member 200 to the position switching locking base structure 100 may be:

Initial state: referring to fig. 3 and 7, the first elastic member 140 is in a relaxed state, and the locking portion 120 has a rotation axis L to switch between the first position and the second position by rotation. At this time, the locking portion 120 is at the first position, along the radial direction of the rotation axis L, the first elastic member 140 is connected to one side of the locking member away from the rotation axis L, the clamping protrusion 121 on the other side of the locking portion 120 away from the rotation axis L abuts against the groove surface of the limiting groove 133 of the first limiting portion 130, and the clamping protrusion 121 abuts against the groove surface to make the first limiting portion 130 at the third position.

Mounting fixture 200: referring to fig. 3 to 5, when the fixing member 200 is required to be installed, the fixing member 200 is placed into the installation cavity of the base 110, the locking portion 120 is pressed while the fixing member 200 is installed, thereby driving the locking portion 120 to rotate from the first position to the second position and compressing the first elastic member 140, and in the process, the clamping protrusion 121 can move to a position separated from the limiting groove 133 so that the second spring releases the elastic force, thereby the first limiting portion 130 moves to the fourth position (see fig. 3 to 5) and can abut against the locking portion 120 to limit the locking portion 120 from moving from the second position to the first position.

And (3) secondary locking: referring to fig. 5 to 6, after the locking portion 120 is located at the second position, the second limiting portion 160 is screwed in, so that the second limiting portion 160 abuts against the locking portion 120, and the locking portion 120 can be limited to move from the second position to the first position.

The operation of unlocking the fixing member 200 can be the reverse of the above-described actions, i.e., the actions of fig. 6 to 3, and fig. 8 to 7, and the disassembly actions will be described below.

Unlocking the second limiting piece: when the fixing piece 200 needs to be disassembled, the second limiting portion 160 is unscrewed, so that the second limiting portion 160 is separated from the locking portion 120, and the locking portion 120 can move from the second position to the first position, and at this time, the clamping protrusion 121 still abuts against the limiting protrusion 132, and the position switching action of the locking portion 120 is limited.

Unlocking the first limiting piece: after unlocking the second stopper, the first stopper 130 is pushed in a direction (see the first direction X) in which the fourth position is directed to the third position, and when the stopper protrusion 132 moves to a position out of the locking protrusion 121, the locking protrusion 121 is moved into the stopper groove 133 in the second direction Y perpendicular to the first direction X by the elastic force of the first spring, and the locking portion 120 moves to the first position. Thereafter, the clamping protrusion 121 abuts against the groove surface of the limiting groove 133 of the first limiting portion 130, so that the first limiting portion 130 is fixed at the third position, and the first spring is in a relaxed state, so that the locking portion 120 is located at the first position.

The foregoing description of the preferred embodiments of the present application should not be construed as limiting the scope of the application, but rather as utilizing equivalent structural changes made in the description and drawings of the present application or directly/indirectly applied to other related technical fields under the application concept of the present application.
