Description

Technical Field

[0001] This application relates to the field of camera extension components, and more particularly to a locking structure and a locking / unlocking method. Background Technology

[0002] A camera quick mount is a connecting device that can be used to mount and secure a camera to a tripod.

[0003] Existing camera quick-release mounts mainly consist of a base and a quick-release plate that can be assembled and disassembled. The base is fixed to the tripod, and the quick-release plate is used to fix the camera. The base and quick-release plate are usually assembled by press or sliding. When the quick-release plate is installed in the base and locked, the self-locking button pops out. To unlock, pressing the self-locking button triggers the locking mechanism to unlock and remove the quick-release plate from the base. Currently, accidental activation / touch of the self-locking button often unlocks the quick-release plate. Some products have a locked and unlocked position for the self-locking button. After the self-locking button pops out, manually sliding it to the locked position can prevent accidental activation. To unlock, sliding the self-locking button to the unlocked position and pressing it triggers the locking mechanism to unlock and remove the quick-release plate from the base. However, this design also makes it easy to forget to switch the self-locking button to the locked position, leading to accidental unlocking.

[0004] Therefore, how to prevent the self-locking structure from being unlocked due to accidental contact has become a technical problem that needs to be solved by those skilled in the art. Summary of the Invention

[0005] One objective of this application is to provide a locking structure to solve the problem of accidental unlocking of a self-locking structure; another objective of this application is to provide a locking and unlocking method applied to the above-mentioned locking structure.

[0006] Firstly, this application provides a locking structure, including:

[0007] The base has mounting grooves on its upper surface for placing mounting components.

[0008] A locking body is located on one side of the mounting groove and is used to lock the mounting component.

[0009] The first self-locking component is disposed inside the base and slidably connected to the base. The first self-locking component can extend one end out of the base under the action of the first self-driving force, and when the extended end of the first self-locking component extends out of the base, the locking body locks the mounting component.

[0010] The second self-locking member is located at the protruding end of the first self-locking member and can be housed inside the first self-locking member. The second self-locking member is used to extend the first self-locking member under the action of the second self-driving force and lock the protruding end of the first self-locking member outside the base.

[0011] When the second self-locking member is pushed back into the first self-locking member, and the extended end of the first self-locking member retracts into the base, the locking body unlocks the mounting piece.

[0012] In some embodiments, the first self-driving force is an elastic force, the first self-locking member is connected to the first elastic member, and the first elastic member is used to provide the first self-locking member with an elastic force away from the locking body; and / or, the second self-driving force is an elastic force, the first self-locking member is provided with a second elastic member, the second elastic member is connected to the second self-locking member and is used to drive the second self-locking member to extend out of the first self-locking member.

[0013] In some embodiments, the locking structure further includes a locking mechanism for locking the second self-locking member within the first self-locking member when the second self-locking member is pressed, and unlocking the second self-locking member when the first self-locking member is pushed back to the base.

[0014] In some embodiments, the movement directions of the first self-locking member and the second self-locking member are perpendicular to each other.

[0015] In some embodiments, the locking mechanism includes a limiting post, a limiting spring, a limiting protrusion disposed in the base, and a limiting groove formed in the second self-locking member;

[0016] The limiting groove is integrally connected along the length direction of the second self-locking member. The opening of the limiting groove includes at least a first opening of a first size and a second opening of a second size, and the first size is larger than the second size.

[0017] The limiting post is set vertically to the second self-locking component. A groove for installing the limiting post is opened in the base. The limiting spring is fitted onto the limiting post. A sliding section, a locking section and a limiting section are arranged in sequence at the end of the limiting post near the second self-locking component. The sliding section is used to slide along the second groove to make the second self-locking component pop out. The locking section is used to lock into the first groove. The limiting section is set in the limiting groove and its size is larger than the first size.

[0018] When the second self-locking component is pressed back to the first self-locking component, the limiting spring pushes the limiting post away from the second self-locking component, and the locking section is locked in the first slot; when the first self-locking component is pushed back into the base, the limiting post touches the limiting protrusion and compresses the limiting spring, the sliding section moves to the second slot and unlocks the second self-locking component.

[0019] In some embodiments, the second self-locking member includes a cylindrical housing, and the second elastic member is a torsion spring disposed within the cylindrical housing and between the first self-locking member; the locking mechanism includes a locking ramp disposed within the base, locking shoulders located on both sides of the locking ramp, and a locking strip flexibly connected to the cylindrical housing in the circumferential direction and conforming to the locking ramp;

[0020] The end of the locking bevel near the second self-locking component is set lower than the locking shoulder and forms a locking groove with the locking shoulder; the end of the locking bevel away from the second self-locking component is set higher than the locking shoulder.

[0021] When the second self-locking component is pressed back to the first self-locking component, the torsion spring is twisted and compressed, and the locking strip slides and stops in the locking groove and locks the second self-locking component; when the first self-locking component is pushed back into the base, the locking strip moves to the high point of the inclined surface and slides out of the locking groove under the action of the torsion spring pushing the second self-locking component, thereby unlocking the second self-locking component.

[0022] In some embodiments, the second self-locking member includes a self-locking member body, and the locking mechanism includes a first hook portion connected to the side of the self-locking member body and a locking spring piece disposed in the base.

[0023] The base is provided with a locking edge and a locking groove at intervals. The locking spring includes a first folded edge, a second folded edge and a second hook part connected in sequence. The second folded edge is placed in the locking groove.

[0024] When the second self-locking member is pressed back to the first self-locking member, the second hook part hooks the first hook part and locks the second self-locking member; when the first self-locking member is pushed back into the base, the first folded edge touches the locking edge and pushes the locking spring piece to move along the locking groove toward the second self-locking member, the second hook part disengages from the first hook part and unlocks the second self-locking member.

[0025] In some embodiments, a receiving groove extending through to the side wall is formed inside the base, and the mounting groove and the receiving groove are vertically connected near the first end of the base; a first self-locking member is disposed in the receiving groove, and a limiting engagement portion is provided at the end of the first self-locking member away from its protruding end; the locking body includes a limiting end and a locking end that extend at an angle, the locking end extends to the mounting groove, and the limiting end is located in the receiving groove and is used to engage with the limiting engagement portion for interlocking.

[0026] In some embodiments, a third elastic element is connected between the locking body and the base, the third elastic element being used to drive the locking body to move in order to lock the first self-locking element.

[0027] Secondly, this application provides a locking and unlocking method applied to the above-mentioned locking structure, including a locking process and an unlocking process;

[0028] The locking process includes:

[0029] Press the mounting piece onto the mounting position on the base, and use the mounting piece to drive the locking body to move and lock the mounting piece;

[0030] Under the action of the first self-driving force, the first self-locking component moves along the first preset direction and extends its protruding end away from the locking body from the base.

[0031] The second self-locking component moves along the second preset direction under the action of the second self-driving force, and locks the protruding end of the first self-locking component to the outside of the base; wherein the first preset direction and the second preset direction are set at an angle;

[0032] The unlocking process includes:

[0033] Pressing the second self-locking member in the opposite direction of the second preset direction releases the lock on the first self-locking member;

[0034] Pressing the first self-locking member in the opposite direction of the first preset direction will unlock the locking body from the first locking position.

[0035] The drive locking body moves from the first locking position to the second locking position and unlocks the mounting piece;

[0036] The first locking position is the position when the locking body locks the mounting piece, and the second locking position is the position when the locking body unlocks the mounting piece.

[0037] In some embodiments, the first preset direction is perpendicular to the second preset direction.

[0038] In some embodiments, the first self-driving force is an elastic force, and / or the second self-driving force is an elastic force.

[0039] In some embodiments, the step of moving the locking body from the first locking position to the second locking position and unlocking the mounting piece specifically involves:

[0040] A third elastic element is pre-installed at the locking body. When the locking body moves from the second locking position to the first locking position, the third elastic element is compressed. When the locking body unlocks from the first locking position, the elastic potential energy of the third elastic element automatically drives the locking body to reset to the second locking position.

[0041] The locking structure provided in this application can be widely used for the installation and fixing of camera extension components and other accessories. When the quick-release plate is installed into the quick-release base, that is, when the mounting component is installed into the base, simply press the mounting component into the mounting groove of the base. The mounting component acts on the locking body, driving the locking body to move. After the locking body rotates, it locks the mounting component in the mounting groove. When the locking body locks the mounting component, the first self-locking component remains in the state where its end, i.e., the second end, protrudes from the base under the action of the first self-driving force. At this time, the first self-locking component will not trigger the locking body to unlock. However, without the restriction of the base, the second self-locking component inside the second end of the first self-locking component protrudes relative to the first self-locking component under the action of the second self-driving force, locking the first self-locking component outside the base. Even if the first or second self-locking component is accidentally touched, it will not cause the first self-locking component to retract into the base and unlock. The automatic locking setting of the second self-locking component to the first self-locking component effectively prevents the locking body from unlocking the mounting component due to accidental touch of the first self-locking component. The locking and unlocking method provided in this application, when applied to the above-mentioned locking structure, has the same beneficial effects. Attached Figure Description

[0063] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0064] The following disclosure provides numerous different embodiments or examples for implementing various structures of the invention. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of the invention. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0065] For ease of description, spatial relative terms may be used in the text to describe the relative position or movement of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "front," "back," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure undergoes a positional flip, orientation change, or change of motion, these directional indications will change accordingly. For instance, an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0066] In order to solve the technical problem of the self-locking mechanism being accidentally unlocked in the prior art, this application provides a locking structure that can automatically lock when the installation part is automatically installed, and at the same time prevent the installation part from being unlocked due to accidental activation of the locking structure.

[0067] It should be noted that the first end of the base mentioned in this article specifically refers to the end of the base where the locking body is located, while the corresponding second end of the base refers to the end of the base away from the locking body, that is, the end where the first self-locking member extends. The first locking position of the locking body refers to the position where the locking body rotates to lock the mounting member after the mounting member is installed into the base, at which point the first locking position is locked and maintained by the first self-locking member; the second locking position of the locking body refers to the position where the locking body rotates to unlock the mounting member after the first self-locking member is pushed back into the receiving groove; the rotation reset of the locking body refers to the process of the locking body rotating from the first locking position to the second locking position.

[0068] This application provides a locking structure, such as... Figure 1As shown, the locking structure mainly includes a base 1, a locking body 2, a first self-locking component 3, and a second self-locking component 4. Taking a camera quick-release mount as an example, the base 1 is generally a plate-shaped component with a certain thickness. An installation groove 10 is formed on the upper surface of the base 1 for the installation component, i.e., the quick-release plate, to be inserted. After the installation component is inserted into the installation groove 10, it acts on the locking body 2. The locking body 2 then locks the installation component. When the locking body 2 is in the locked position, the first self-locking component 3 is in a state where its end, i.e., the second end / protruding end, extends out of the base 1 under the action of the first self-driving force. The second self-locking component 4, located inside the first self-locking component 3, is no longer restricted by the base 1 and extends relative to the first self-locking component 3 under the action of the second self-driving force, locking the second end / protruding end of the first self-locking component 3 outside the base 1. This effectively prevents accidental contact with the first self-locking component 3 from causing the locking body 2 to unlock the installation component. To unlock the mounting piece, simply press the second self-locking piece 4 back into the first self-locking piece 3, then push the first self-locking piece 3 back into the base 1, and use the first self-locking piece 3 to trigger the locking body 2 to unlock.

[0069] It is important to emphasize here that a key point of this application is the automatic locking structure of the second self-locking member 4 against the first self-locking member 3, preventing the first self-locking member 3 from being accidentally activated and causing the locking body 2 to unlock. When the locking body 2 locks the mounting piece, the first self-locking member 3 has a state association where its second end / extended end extends out of the base 1, but not necessarily an action association. That is, the action of the first self-locking member 3 extending its second end / extended end out of the base 1 under the action of the first self-driving force can occur before the locking body 2 locks the mounting piece, or the mounting piece triggers the movement of the locking body 2, and the locking body 2 unlocks during the process of locking the mounting piece and triggers the movement of the first self-locking member 3, after which its second end / extended end extends out of the base 1. The following will use the structure where the locking body 2 triggers the movement of the first self-locking member 3 to extend out of the base 1 when locking the mounting piece as an example to explain the working process of the locking structure. The same applies to the structure where the locking body 2 does not directly trigger the first self-locking member 3 to extend out of the base.

[0070] Please see Figures 1 to 4 In one specific embodiment provided in this application, a receiving groove 11 is formed inside the base 1, and a first self-locking member 3 is installed in the receiving groove 11 and can reciprocate along the receiving groove 11 under the action of its first self-driving force and external force respectively. The receiving groove 11 extends substantially from the first end to the second end of the base 1 and penetrates the side wall of the base 1 at the second end of the base 1, so that the end of the first self-locking member 3 extends out of the receiving groove 11 under the action of the first self-driving force.

[0071] The first end of the receiving groove 11 is connected upward to the mounting groove 10. The locking body 2 is placed on the first end of the base 1 and rotatably connected to the base 1. The locking end 21 of the locking body 2 extends out of the mounting groove 10 and has a preset arc that bends toward the second end of the base 1 so that the mounting part can be fastened and fixed after rotation. The limiting end 23 of the locking body 2 is located in the receiving groove 11. The limiting end 23 can interlock with the first end of the first self-locking member 3. The limiting end 23 and the locking end 21 are set at an angle of approximately 90° or greater than 90°. In some cases, in order to facilitate the ejection of the mounting part, the locking body 2 is usually also provided with a lifting end 22, which is located between the locking end 21 and the limiting end 23.

[0072] When the mounting component is not installed, the locking body 2 is held in the second locking position. At this time, the lifting end 22 protrudes relative to the bottom of the mounting groove 10, and the limiting end 23 fits against the top of the receiving groove 11. When the mounting component is installed into the mounting groove 10, the second end of the mounting component needs to be aligned with the second end of the mounting groove 10, and the first end of the mounting component is pressed down. The first end of the mounting component is inserted into the mounting groove 10. During this process, the lifting end 22 is pressed down by the mounting component, which drives the locking body 2 to rotate. The lifting end 22 rotates into the receiving groove 11, the locking end 21 rotates to engage the mounting component, and the limiting end 23 rotates and is locked by the first self-locking component 3.

[0073] The first self-locking member 3 is installed in the receiving groove 11 and is driven by the first self-driving force, tending to move toward the second end of the base 1, that is, the first self-locking member 3 has a tendency to extend its second end out of the receiving groove 11. The first end of the first self-locking member 3, that is, the end near the locking body 2, is provided with a limiting engagement part 31, and the limiting engagement part 31 and the limiting end 23 of the locking body 2 have two interlocking states. When the locking body 2 is in the second locking position, the limiting end 23 and the limiting engagement part 31 are interlocked to prevent the first self-locking member 3 from extending out of the receiving groove 11 under the action of the first self-driving force; when the locking body 2 moves to the first locking position, the first self-locking member 3 is unlocked, and after the first self-locking member 3 moves a certain distance toward the second end of the base 1 under the action of the first self-driving force, the limiting engagement part 31 interlocks again when it contacts the limiting end 23, and the first self-locking member 3 cannot continue to extend. At the same time, the rotation of the limiting end 23 is restricted, thus keeping the locking body 2 in the first locking position, and the mounting part is locked.

[0074] The unlocking process is the opposite. The first self-locking member 3 is pressed back into the receiving groove 11, the limiting engagement part 31 disengages from the limiting end 23, and the locking body 2 is unlocked from the first locking position. The locking body 2 rotates back to the second locking position to unlock the mounting piece. The limiting engagement part 31 and the limiting end 23 abut against each other again to lock the limiting engagement part 31, that is, to lock the first self-locking member 3 in the receiving groove 11. During this process, the driving force for the locking body 2 to rotate back from the first locking position to the second locking position can be a manually input external force, or it can be a torsional torque generated by the elastic force of a spring or torsion spring and acting on the locking body 2.

[0075] A slot is formed in the second end of the first self-locking member 3, which is roughly perpendicular to the movement direction of the first self-locking member 3. The second self-locking member 4 is installed in the slot at the end of the first self-locking member 3, and a second self-driving force is used to drive the second self-locking member 4 to extend out of the first self-locking member 3. The second self-driving force can be a compressive elastic force or a magnetic repulsive force. When the first self-locking member 3 is located in the receiving groove 11, the second self-locking member 4 is limited by the side wall of the receiving groove 11 and cannot extend out of the first self-locking member 3. When the end of the first self-locking member 3, that is, the second end, extends out of the receiving groove 11, under the action of the second self-driving force, the second self-locking member 4 automatically pops out of the first self-locking member 3, locking the end of the first self-locking member 3 outside the receiving groove 11. At this time, whether the first self-locking member 3 or the second self-locking member 4 is accidentally touched, the first self-locking member 3 cannot return to the receiving groove 11, thereby avoiding accidental release of the locking state of the locking body 2 on the mounting part. The second self-locking component 4 can be equipped with a suitable limiting structure to prevent it from fully popping out and disengaging from the first self-locking component 3.

[0076] The complete work process is as follows:

[0077] 1. When the mounting component is not installed, the locking body 2 is in the second locking position, the lifting end 22 protrudes from the bottom of the mounting groove 10, the limiting end 23 of the locking body 2 is attached to the top of the receiving groove 11, and the bottom of the limiting end 23 is attached to and locked to the top of the limiting mating part 31 of the first self-locking component 3, so that the first self-locking component 3 is locked in the receiving groove 11.

[0078] 2. When the mounting component is inserted into the mounting groove 10, the lifting end 22 of the locking body 2 is pressed down and the locking body 2 is rotated to the first locking position. The limiting end 23 rotates towards the bottom of the receiving groove 11. The limiting mating part 31 of the first self-locking component 3 disengages from the limiting end 23 of the locking body 2. Under the action of the first self-driving force, the first self-locking component 3 moves a certain distance toward the second end of the base 1. The limiting mating part 31 moves to the top of the locking end 21 and presses and fixes the locking end 21. The locking body 2 is locked to the first locking position and the mounting component is locked. At the same time, the end of the first self-locking component 3 extends out of the receiving groove 11. Under the action of the second self-driving force, the second self-locking component 4 pops out the first self-locking component 3 and stops the end of the first self-locking component 3 outside the receiving groove 11.

[0079] 3. When it is necessary to remove the mounting component, first press the second self-locking component 4 back into the first self-locking component 3, and then press the first self-locking component 3 back into the receiving groove 11. At this time, the first self-locking component 3 moves toward the first end of the receiving groove 11, the limiting fitting part 31 moves away from the top of the limiting end 23, the locking body 2 unlocks from the first locking position and rotates from the first locking position to the second locking position, the lifting end 22 rotates to the bottom surface protruding from the mounting groove 10, lifting the mounting component away, and the limiting end 23 rotates to fit the top of the receiving groove 11. After releasing the first self-locking component 3, the first self-locking component 3 tends to extend out of the receiving groove 11 under the drive of the first self-driving force, the limiting fitting part 31 moves to the limiting end 23 and fits the bottom of the limiting end 23 and is limited and locked, the first self-locking component 3 is locked in the receiving groove 11, thereby restoring the state of not having the mounting component installed. As mentioned above, the driving force for the locking body 2 to rotate from the first locking position to the second locking position can be a manually input external force, or it can be a torsional torque generated by the elastic force of a spring or torsion spring and acting on the locking body 2.

[0080] The interlocking process of the limiting end 23 and the limiting mating part 31 will be described below with reference to the accompanying drawings and embodiments.

[0081] Further reading Figure 2 and Figure 4 In one specific embodiment provided in this application, the upper surface of the limiting end 23 includes at least one inclined surface, which is defined here as the first limiting inclined surface 231. When the limiting end 23 is rotated to the parallel receiving groove 11, the first limiting inclined surface 231 extends from the bottom to the top from the first end of the base 1 to the second end of the base 1. The first self-locking member 3 includes at least one rod body that can move along the receiving groove 11. The limiting mating part 31 protrudes from one side of the first end of the rod body and can touch the limiting end 23.

[0082] The lower surface of the limiting mating part 31 is provided with a second limiting inclined surface 311. The second limiting inclined surface 311 extends from the bottom to the top from the first end of the base 1 to the second end of the base 1 to ensure that it fits and limits the first limiting inclined surface 231. When the locking body 2 is in the second locking position, the limiting end 23 is in contact with the top of the receiving groove 11, and the bottom corner abuts against the top corner of the limiting mating part 31, locking the first self-locking member 3 in the receiving groove 11; when the mounting part is inserted into the mounting groove 10, the lifting end 22 is pressed down, and the limiting end 23 moves towards the bottom of the receiving groove 11 and disengages from the limiting mating part 31. The first self-locking member 3 is unlocked and extends out of the receiving groove 11 under the action of the first self-driving force. When it moves to the second limiting inclined surface 311 of the limiting mating part 31 and is in contact with the first limiting inclined surface 231 of the limiting end 23, the first self-locking member 3 is stuck and cannot continue to extend. At the same time, under the action of the first self-driving force, the first self-locking member 3 causes the second limiting inclined surface 311 to press against the first limiting inclined surface 231, keeping the locking body 2 in the first locking position. When unlocking, when the first self-locking member 3 is pressed back into the receiving groove 11, the first limiting inclined surface 231 and the second limiting inclined surface 311 disengage, the locking body 2 rotates and resets to the second locking position, the limiting end 23 rotates to fit the top of the receiving groove 11, and the bottom corner of the limiting end 23 abuts against the top corner of the limiting mating part 31 again, locking the first self-locking member 3 in the receiving groove 11.

[0083] It is worth noting that the first limiting inclined surface 231 and the second limiting surface are only provided to facilitate the formation of a certain space between the limiting end 23 and the limiting mating part 31 after the limiting end 23 rotates downward, so that the first self-locking member 3 can move and extend out of the receiving groove 11. In specific implementation, the contact mating surface between the limiting end 23 and the limiting mating part 31, such as a concave-convex mating surface, can be set as needed, and no specific limitation is made here. The interlocking structure of the limiting end 23 and the limiting mating part 31 can also be flexibly set with reference to the above embodiments and the prior art.

[0084] Continue reading Figure 2 and Figure 3 As one implementation of this application embodiment, the first self-driving force can specifically be an elastic force. A first elastic element 32 can be connected to the first self-locking element 3, and the first elastic element 32 can provide the first self-locking element 3 with an elastic force that moves it away from the locking body 2. The first elastic element 32 can be a spring as shown in the figure. One end of the spring abuts against the groove wall of the receiving groove 11, and the other end is connected to the rod body of the first self-locking element 3. When the first self-locking element 3 is located in the receiving groove 11, the spring is in a compressed state. The first self-driving force can also be a magnetic attraction force or a magnetic repulsion force, which will not be described in detail here.

[0085] Similarly, the second self-driving force can also be an elastic force. A slot is formed at the end of the first self-locking member 3, which is also the second end, perpendicular to the direction of movement of the first self-locking member 3. The second self-locking member 4 is installed in the slot and can extend relative to the first self-locking member 3 under the second self-driving force. Thus, when the end of the first self-locking member 3 extends out of the receiving slot 11, the second self-locking member 4 automatically pops out, locking the first self-locking member 3 outside the receiving slot 11, preventing accidental activation of the first self-locking member 3 to unlock the mounting component. Alternatively, the second self-driving force can also be a magnetic repulsion force.

[0086] Based on the above embodiments, to facilitate the installation and unlocking of the mounting components, the locking structure provided in this application embodiment further includes a third elastic member 24. The third elastic member 24 is used to hold the locking body 2 in the second locking position, or, after the locking body 2 is unlocked, drive the locking body 2, which is in the first locking position, to rotate and reset to the second locking position. (See attached document) Figure 2 The third elastic element 24 can be a spring located between the bottom of the locking body 2 and the bottom of the receiving groove 11. When the spring is in a pre-locked state and the mounting piece is not installed, the locking body 2 is held in the second locking position because the spring force causes the limiting end 23 to adhere to the top of the receiving groove 11. After the mounting piece is installed, the locking body 2 rotates to the first locking position, the spring is compressed, the first self-locking element 3 unlocks and extends out of the receiving groove 11 and locks the locking body 2 in the first locking position. When unlocking, the first self-locking element 3 is pushed back into the receiving groove 11, unlocking the locking body 2 from the first locking position. Under the action of the spring force, the locking body 2 is driven to rotate and reset to the second locking position.

[0087] Understandably, the third elastic element 24 can also be a torsion spring, which is torsionally connected between the locking body 2 and the base 1 to provide the locking body 2 with a torsional torque to rotate to the second locking position. Of course, without the third elastic element 24, the locking body 2 can also be manually rotated to the second locking position.

[0088] In the above embodiment, when the first self-locking member 3 extends out of the receiving groove 11 to lock the locking body 2, the second self-locking member 4 automatically pops out under the action of the second self-driving force to lock the first self-locking member 3 outside the receiving groove 11, effectively preventing the first self-locking member 3 from being accidentally touched and unlocking the mounting piece. However, when unlocking, it is necessary to continuously press the second self-locking member 4 and push the first self-locking member 3 back into the receiving groove 11, which is somewhat inconvenient.

[0089] In view of this, this application further improves the locking structure, particularly by adding a locking mechanism within the locking structure. This allows the second self-locking member 4 to be locked when pressed back into the first self-locking member 3, at which point the mounting piece can be unlocked simply by pushing the first self-locking member 3. Simultaneously, after the first self-locking member 3 is pushed back into the receiving groove 11, the second self-locking member 4 will automatically unlock, so that when the first self-locking member 3 extends out of the receiving groove 11 again, the second self-locking member 4 will automatically pop out and lock the first self-locking member 3 outside the receiving groove 11. The working process of the second locking body 2 and the locking mechanism will be described below using three embodiments.

[0090] In one embodiment, see [reference] Figure 5 and Figure 6 The second self-locking member 4 compresses the second elastic member 41 into the groove of the first self-locking member 3. The locking mechanism mainly consists of a limiting post 5, a limiting spring 52, a limiting protrusion 12, and a limiting groove formed on the second self-locking member 4. The limiting post 5 extends in the same direction as the first self-locking member 3 and is set approximately perpendicular to the second self-locking member 4. A recessed groove is formed in the receiving groove 11, the length of which is greater than the length of the limiting post 5. A limiting protrusion 12 is set at one end of the recessed groove near the locking body 2. The limiting spring 52 is fitted onto the limiting post 5. A spring limiting disc 51 is set at the first end of the limiting post 5, and the second end of the limiting post 5 is inserted into the limiting groove of the second self-locking member 4. The second elastic member 41 is set in... Figure 9 Similar to the Chinese.

[0091] The limiting post 5, from its second end to its first end, includes a limiting section 55, a locking section 54, a sliding section 53, and a main body. The limiting spring 52 is fitted onto the main body. The sliding section 53 is smaller than the locking section 54, and the locking section 54 is smaller than the limiting section 55. Correspondingly, the inner size of the limiting groove is larger than the limiting section 55. The groove opening is a widened groove. The groove opening is set as a second groove 35 and a first groove 34 from the direction near the second elastic member 41 to the direction away from the second elastic member 41. The size of the second groove 35 is larger than the sliding section 53 of the limiting post 5 and smaller than the locking section 54. The size of the first groove 34 is greater than or equal to the locking section 54 and smaller than the first limiting section 55, thereby preventing the limiting post 5 from coming off the second elastic member 41. After the second end of the limiting post 5 is inserted into the limiting groove of the second self-locking member 4, the limiting spring 52 is in a compressed state.

[0092] The working process is as follows: When the second self-locking member 4 pops out from the first self-locking member 3, the sliding section 53 of the limiting post 5 corresponds to the second slot 35 of the limiting groove. When the second self-locking member 4 is pressed back to the first self-locking member 3, the first slot 34 slides to the limiting post 5. Driven by the limiting spring 52, the limiting post 5 tends to disengage from the second self-locking member 4. The locking section 54 moves to the first slot 34 and abuts against the second slot 35, locking the second self-locking member 4 inside the first self-locking member 3. When the first self-locking member 3 is pushed back into the receiving groove 11, the limiting post 5 moves along the groove. When the first end of the limiting post 5 touches the limiting protrusion 12, the limiting spring 52 is compressed, the locking section 54 disengages from the first slot 34, and the sliding section 53 corresponds to the first slot 34. Under the drive of the second elastic member 41, the second self-locking member 4 moves slightly and fits against the side wall of the receiving groove 11. The second slot 35 slides to the corresponding sliding section 53, unlocking the second self-locking member 4. After the end of the first self-locking member 3 pops out of the receiving groove 11, it loses the limitation of the side wall of the receiving groove 11, and the second self-locking member 4 automatically pops out under the drive of the second elastic member 41.

[0093] It should be noted that when the second self-locking member 4 is pressed back and locked by the first self-locking member 3, and the first self-locking member 3 is pushed back into the receiving groove 11, there is a certain clearance space between the second self-locking member 4 and the side wall of the receiving groove 11, so that the limiting post 5 can touch the limiting protrusion 12. When the sliding section 53 corresponds to the first slot 34, the first self-locking member 3 can move slightly to use the second slot 35 to lock the sliding section 53 and unlock the second self-locking member 4.

[0094] To facilitate assembly, the limiting groove also includes an installation groove 33 located on the side of the second groove 35 away from the second elastic member 41. The size of the installation groove 33 is larger than the size of the limiting section 55. After the limiting section 55 is inserted from here, it restricts the second end of the limiting post 5 within the limiting groove. Of course, the second self-locking member 4 can also be in a two-part structure, where the limiting section 55 is snapped into the limiting groove through assembly. In this case, the installation groove 33 is not required.

[0095] Another embodiment of this application provides a carding mechanism such as... Figure 7 As shown, the second self-locking member 4 adopts a cylindrical shell / cap-shaped shell, and the second elastic member 41 adopts a torsion spring. The torsion spring provides the second self-locking member 4 with torsional torque and elastic force to eject the first self-locking member 3. The locking mechanism includes a locking ramp 13 disposed in the receiving groove 11, locking shoulders 14 located on both sides of the locking ramp 13, and a locking strip 42 flexibly connected to the cylindrical shell / cap-shaped shell. Among them, the lower point of the locking ramp 13 near the second self-locking member 4 is set lower than the locking shoulder 14, and the higher point of the locking ramp 13 away from the second self-locking member 4 is set higher than the locking shoulder 14, thereby forming a locking groove between the two locking shoulders 14.

[0096] When the second self-locking member 4 pops out of the first self-locking member 3, the locking strip 42 is in the unfolded state and corresponds to the locking shoulder 14; when the second self-locking member 4 is pressed back into the first self-locking member 3, the second elastic member 41, i.e., the torsion spring here, is compressed, and the locking strip 42 slides into the locking groove to lock the second self-locking member 4 into the first self-locking member 3; when the first self-locking member 3 is pushed back into the receiving groove 11, the locking strip 42 moves along the inclined surface, and at the same time the second self-locking member 4 is moderately twisted. When the locking strip 42 moves to the high point of the inclined surface, it disengages from the locking groove and slides towards the locking shoulder 14 under the action of the second elastic member 41 to unlock the second self-locking member 4. At this time, the second self-locking member 4 pops out appropriately and is limited by the side wall of the receiving groove 11. When the first self-locking member 3 extends out of the receiving groove 11, the second self-locking member 4 pops out automatically. It should also be noted that when the second self-locking member 4 is locked inside the first self-locking member 3 and the first self-locking member 3 is pushed back into the receiving groove 11, the second self-locking member 4 and the side wall of the receiving groove 11 have an appropriate amount of clearance space so that the second self-locking member 4 pops out appropriately to drive the locking strip 42 out of the locking groove and unlock the second self-locking member 4.

[0097] In some embodiments, see Figure 8 and Figure 9 The second self-locking component 4 includes a self-locking component body, and the locking mechanism includes a first hook part 43 connected to the side of the self-locking component body and a locking spring piece 6 disposed in the receiving groove 11. The locking and unlocking of the second self-locking component 4 are achieved by hooking and disengaging the spring piece and the first hook part 43.

[0098] The locking spring 6 includes a first folded edge 61, a second folded edge 62, and a third folded edge. The end of the third folded edge is bent to form a second hook portion 63. The first folded edge 61 and the second hook portion 63 are arranged opposite to each other. The receiving groove 11 has a locking groove (not shown in the attached figure) that extends generally along the movement direction of the first self-locking member 3. The second folded edge 62 is placed in the locking groove so that the locking spring 6 can slide along the locking groove. The receiving groove 11 is also provided with a locking edge 15 for abutting against the first folded edge 61. When the first self-locking member 3 extends out of the receiving groove 11 and the second self-locking member 4 extends out of the first self-locking member 3, the first hook portion 43 and the second hook portion 63... When the second self-locking member 4 is pressed back to the first self-locking member 3, the first hook part 43 touches the second hook part 63. After the second hook part 63 deforms, it locks the first hook part 43, thereby locking the second self-locking member 4 inside the first self-locking member 3. When the first self-locking member 3 is pushed back to the receiving groove 11, it drives the locking spring 6 to move along the locking groove. The first folded edge 61 touches the locking edge 15. The second self-locking member 4 continues to move and misaligns with the locking spring 6, and then disengages from the second hook part 63. Under the elastic force of the second elastic member 41, it pops out appropriately and is limited by the side wall of the receiving groove 11, thereby unlocking the second self-locking member 4. During this process, when the second self-locking member 4 is pressed back to the first self-locking member 3 and the first self-locking member 3 is pushed back to the receiving groove 11, the second self-locking member 4 and the side wall of the receiving groove 11 also reserve appropriate clearance space so that the second self-locking member 4 can move and unlock within the receiving groove 11.

[0099] In the above embodiments, to facilitate the installation of components such as the first self-locking component 3, the base 1 is typically provided with a detachable base plate. After the first self-locking component 3 is inserted into the receiving groove 11, the base plate is installed onto the base 1 to close the receiving groove 11. The base plate is equivalent to the bottom of the receiving groove 11. The base plate and the base 1 can be detachably connected by fasteners such as screws. Figure 3 This is a schematic diagram showing the installation of the first self-locking component 3 and the locking body 2 in the receiving groove 11 after the bottom plate is removed.

[0100] This application also provides a locking and unlocking method, applied to the locking structure provided in the above embodiments, see below. Figure 10 and Figure 11 The locking and unlocking method includes a locking process and an unlocking process;

[0101] The locking process is as follows:

[0102] Step S10: Press the mounting piece to the mounting position on the base, and lock the mounting piece by using the mounting piece to drive the locking body to move;

[0103] Step S20: Under the action of the first self-driving force, the first self-locking component moves along the first preset direction and extends its extended end away from the locking body from the base;

[0104] Step S30: The second self-locking member moves along the second preset direction under the action of the second self-driving force, and locks the protruding end of the first self-locking member outside the base; wherein the first preset direction and the second preset direction are set at an angle;

[0105] The unlocking process includes:

[0106] Step S40: Press the second self-locking member in the opposite direction of the second preset direction to release the lock on the first self-locking member;

[0107] Step S50: Press the first self-locking member in the opposite direction of the first preset direction to unlock the locking body from the first locking position;

[0108] Step S60: Drive the locking body from the first locking position to the second locking position and unlock the mounting piece.

[0109] Step S10 specifically involves pressing the mounting component into the mounting position, which is the mounting slot corresponding to the embodiment above. The mounting component drives the locking body to move. After the locking body moves, it locks the mounting component in the mounting position. At this time, the locking body is in the first locking position. The first locking position here refers to the position where the locking body is when locking the mounting component.

[0110] Step S20 specifically involves the first self-locking member moving along a first preset direction under the action of the first self-driving force while maintaining the state of its second end extending. This process can occur before or after the mounting member is installed in the mounting position. When the first self-locking member is only used to drive the locking body to unlock, steps S10 and S20 are not sequential. Step S10 must precede step S20 only when there is an interlocking relationship between the first self-locking member and the locking body, that is, when the first self-locking member is locked by the locking body before it extends out of the base. In this case, the movement of the locking body triggers the unlocking of the first self-locking member.

[0111] In step S30, when the second end / extended end of the first self-locking member is in an extended state relative to the base, the second self-locking member automatically extends relative to the first self-locking member along a second preset direction under the action of the second self-driving force, since the limiting effect of the base is lost. Here, the first direction and the second direction are set with different directions to effectively avoid accidental contact with a certain part that would cause the locking body to unlock.

[0112] In some implementations, to improve the reliability of locking, the first preset direction and the second preset direction can be set as two mutually perpendicular directions. For example, a slot is opened at the corresponding position of the first self-locking member, and the extension direction of the slot is set perpendicular to the movement direction of the first self-locking member; the second self-locking member is installed in the slot of the first self-locking member, and the second self-locking member moves along the slot of the first self-locking member, thereby realizing that the movement directions of the first self-locking member and the second self-locking member are perpendicular to each other.

[0113] The first and second self-driving forces ensure that the mounting component automatically locks after being inserted into the mounting position, preventing accidental unlocking due to forgetting to lock it. These first and second self-driving forces can be elastic or magnetic.

[0114] The unlocking process is the reverse of the locking process described above. First, step S40 is required: the second self-locking component is reset in the opposite direction of the second preset direction, thereby releasing the first self-locking component from the locked state; then step S50 is required: the first self-locking component is moved in the opposite direction of the first preset direction, releasing the locking body; finally, step S60 is required: the locking body is driven to rotate from the first locking position to the second locking position, releasing the mounting component from the locked state. When the first self-locking component and the locking body have an interlocking relationship, after the locking body moves to the second locking position, it also limits and locks the first self-locking component, preventing the first self-locking component from moving under the action of the first self-driving force; when the first self-locking component is only used to drive the locking body to unlock, after the first self-locking component triggers the locking body to unlock, it returns to the extended position under the action of the first self-driving force.

[0115] In some embodiments, step S60, which drives the locking body to move from the first locking position to the second locking position, employs an elastic automatic drive. That is, by pre-positioning a third elastic element at the locking body, the third elastic element holds the locking body in the second locking position. When the mounting component is installed, the mounting component drives the locking body to rotate from the second locking position to the first locking position and lock it by the first self-locking element. At this time, the third elastic element is compressed to generate elastic potential energy. During the unlocking process, the first self-locking element resets, the locking body unlocks from the first locking position, and the third elastic potential energy drives the locking body to automatically reset to the second locking position, thus unlocking the mounting component.
