[0017] The technical solutions of the present application are described clearly and completely below with reference to the accompanying drawings. It is understood that the described embodiments represent only a portion of the embodiments of the present application and do not encompass all embodiments. All further embodiments that a person skilled in the art in this field arrives at based on the present embodiments without any inventive effort fall within the scope of protection of the present application.

[0018] It is understood that the terms “comprises” and “includes”, as used in this description and the attached claims, indicate the presence of the described features, units, steps, processes, elements and / or components, but do not exclude the presence or addition of one or more other features, units, steps, processes, elements, components and / or combinations thereof.

[0019] It is further understood that the terms used in the description of this application serve only to describe certain embodiments and are not intended to limit this application. As used in the description of this application and the attached claims, the terms "a", "an", and "the" in the singular form are intended to include the plural form unless the context clearly indicates otherwise.

[0020] It is further understood that the term “and / or” used in the description and the attached claims refers to and includes any combination of one or more of the related elements and all possible combinations. Example 1:

[0021] With reference to the Fig. Figures 1 to 3 describe a first embodiment of the present application, providing a portable release stand that simplifies the structure of existing stands. The user can quickly lock and unlock the stand by means of simple operation, thus increasing the stand's ease of use. The present application relates to the stand in a vertical position.

[0022] In particular, the stand comprises a locking arrangement 1 and an installation bracket 2, wherein an installation groove 21 is formed on a top surface of the installation bracket 2, and wherein a limiting groove 22 is formed on an inner side wall of the installation bracket 2; wherein the locking arrangement 1 comprises a drive element 6, a sliding element 7, and a locking element 8, wherein one end of the drive element 6 is rotatably connected to the installation bracket 2, wherein the sliding element 7 is slidably mounted on the installation groove 21 in a vertical direction, and wherein the drive element 6 partially bears against the sliding element 7 in order to press the sliding element 7; wherein the locking element 8 penetrates the sliding element 7 and is secured in the installation groove 21, and wherein the sliding element 7 is used to lock the locking element 8;wherein a limiting structure 9 is provided on a side surface of the sliding element 7, wherein the limiting structure 9 is released from the limiting groove 22 when the stand is in a locked state, wherein the limiting structure 9 is engaged and limited in the limiting groove 22 when the stand is in an unlocked state.

[0023] To unlock the stand, the user presses the drive element 6 downwards, which depresses the sliding element 7. This causes the sliding element 7 to slide vertically within the installation groove 21, disengaging its upper surface from the underside of the locking element 8. When the limiting structure 9 on the side face of the sliding element 7 slides along the limiting groove 22 and engages within it, the stand is unlocked. When the stand is locked, the limiting structure 9 on the side face of the sliding element 7 disengages from the limiting groove 22, resetting the sliding element 7 upwards and bringing it into contact with the underside of the locking element 8.In comparison to the complex locking structures of conventional stands, the present application significantly simplifies the manufacturing process and assembly procedure, reduces costs and thus simplifies the steps for locking and unlocking the stand, thereby increasing work efficiency and ease of use.

[0024] With reference to Fig. 2. In a specific embodiment, the stand further comprises a torsion spring 3, wherein a support column 23 is provided in the center of the installation groove 21, wherein the locking element 8 is fixedly connected to the support column 23, wherein the sliding element 7 is slidably mounted on an outer surface of the support column 23 in a vertical direction, wherein the torsion spring 3 is mounted on an outer surface of the support column 23, and wherein both ends of the torsion spring 3 bear against a bottom wall of the installation groove 21 and the sliding element 7, respectively. The torsion spring 3 not only provides the necessary spring force but also increases to some extent the structural stability of the entire locking assembly 1.By connecting the torsion spring 3 to the support column 23, the bottom wall of the installation groove 21 and the sliding element 7, the connection between the individual components becomes firmer, thereby reducing wobbling and loosening of the components, which contributes to improving the overall service life and reliability of the stand.

[0025] When the stand is unlocked and the drive element 6 pushes the sliding element 7 downwards, the torsion spring 3 is elastically deformed. As soon as the drive element 6 no longer presses on the sliding element 7, the torsion spring 3 uses its elastic energy to push the sliding element 7 upwards back to its starting position, so that it rests against the underside of the locking element 8 and is thus limited in its movement. This achieves automatic resetting and locking of the stand without the user having to manually push the sliding element 7 back into its starting position, further increasing ease of use and simplifying the entire operating procedure.

[0026] In a specific embodiment, the sliding element 7 comprises an upper section 10 and a projecting section, which are formed in one piece. Sliding grooves 18 extend through both opposite sides of the upper section 10, with connecting shafts 25 projecting from both sides of the support column 23 corresponding to the sliding grooves 18, each connecting shaft 25 passing through the two sliding grooves 18. One end of the drive element 25 is mounted on the connecting shaft 25, and the drive element 6 can rotate about the connecting shaft 25; when the drive element 6 is pressed, a curved section of the drive element 6 bears against the projecting section 11.

[0027] Here, the sliding element 7 can slide precisely in the vertical direction within the sliding groove 18 along the connecting shaft 25 on the support column 23. The interaction of the sliding grooves 18 and the connecting shafts 25 serves as a guide and ensures that the sliding element 7 can only move in the predetermined vertical direction, thereby limiting its displacement in other directions and thus ensuring the accuracy of the locking and unlocking operations of the stand. At the same time, this interaction increases the contact area between the sliding element 7 and the support column 23, resulting in a smoother sliding process and reducing wobbling and jerking.

[0028] One end of the drive element 6 is rotatably connected to two connecting shafts 25. When the drive element 6 is pressed, a curved portion rests against the projecting section 11, enabling the drive element 6 to effectively transmit the external force to the sliding element 7. The rotatable connection of the drive element 6 to the connecting shafts 25 provides the drive element 6 with a flexible pivot point, allowing the user to actuate the drive element 6 with a simple rotational movement. The curved portion of the drive element 6 rests against the projecting section 11 of the sliding element, ensuring that when the drive element 6 is pressed, the force is precisely applied to the sliding element 7, thereby pushing the sliding element 7 downwards in the vertical direction and unlocking the stand.This type of connection and attachment ensures a more direct and efficient drive of the sliding element 7 by the drive element 6 and allows the user more convenient and less strenuous operation.

[0029] With reference to Fig. 2 and Fig. 3. In a specific embodiment, the limiting groove 22 is L-shaped, with the limiting structure 9 projecting from an outer side wall of the preceding section 11. When the drive element 6 is pressed, the limiting structure 9 slides along a vertical end of the limiting groove 22 and is engaged and limited at a horizontal end of the limiting groove 22.

[0030] The L-shaped limiting groove 22 fits the limiting structure 9 on the outer side wall of the protruding section 11, thus enabling precise limiting of the position of the sliding element 7 when unlocking the stand. When the drive element 6 is pressed, the sliding element 7 initially moves the limiting structure 9 along the vertical end of the limiting groove 22. Once the limiting structure 9 has engaged at the horizontal end of the limiting groove 22, the sliding element 7 has reached the exact unlocking position, and the stand is in a stable, unlocked state.

[0031] To lock the stand, the user rotates the drive element 6 horizontally. The drive element 6 imparts a horizontal rotation to the sliding element 7, causing the limiting structure 9 to slide from the horizontal end of the limiting groove 22 to the vertical end. This movement is driven by the elastic energy of the torsion spring 3 until the top of the sliding element 7 rests against the bottom of the locking element 8, thus locking the stand. The limiting structure 9 slides within the limiting groove 22, preventing the sliding element 7 from moving in any other, undesired direction. As a result, the stand remains stable after unlocking or locking and does not wobble or deform due to minor external influences, thus increasing the stand's stability and reliability during use.

[0032] Furthermore, one end of the limiting structure 9, the end furthest from the sliding element 7, has a curved surface. This curved surface allows the limiting structure 9 to slide more smoothly in the limiting groove 22, thus reducing jamming; it also facilitates smoother engagement when the limiting structure 9 is engaged at the horizontal end of the limiting groove 22. Likewise, the curved surface makes it easier to release the limiting structure 9 from the horizontal end of the limiting groove 22, reduces actuation resistance, and ensures a more convenient and smoother unlocking and locking process of the stand. There is line or point contact between the curved surface and the limiting groove 22.In comparison to surface contact, less friction is generated during sliding and locking, which effectively reduces wear between the limiting structure 9 and the limiting groove 22 and extends the service life of the limiting structure 9 and the limiting groove 22.

[0033] In a specific embodiment, the locking element 8 comprises a ball 19 and a sleeve 20. A lower end of the ball 19 penetrates the sliding element 7 and is fixed inside the support column 23, the sleeve 20 being rotatably mounted on an outer surface of the ball 19, with an upper surface of the sliding element 7 bearing against an underside of the sleeve 20.

[0034] The sleeve 20 is rotatably mounted on the ball 19, allowing it to rotate freely relative to the ball 19. During use of the stand, this rotational flexibility enables adaptation to various application scenarios and angle adjustment requirements. For example, if the support angle of the stand needs to be adjusted, the sleeve 20 can be rotated to different positions to better meet the user's requirements for adjusting the stand's posture.

[0035] The lower end of the ball 19 penetrates the sliding element 7 and is attached to the support column 23, thus ensuring the stable installation of the ball 19 on the support column 23 and providing a solid foundation for the entire locking structure. The upper surface of the sliding element 7 rests against the underside of the sleeve 20. When the sliding element 7 is reset to its upward position, its upper surface rests firmly against the underside of the sleeve 20, thereby locking the sleeve 20. This restricts the movement of the parts associated with the sleeve 20 and thus serves to lock the stand. This design enables precise locking and positioning, ensures the stability and reliability of the stand in the locked state, and prevents unintentional unlocking or wobbling of the stand. Example 2

[0036] With reference to Fig. 4 and Fig. 5 The main difference between this embodiment and the first embodiment is that the stand further comprises a pressure element 4 and a first spring 29, wherein both ends of the first spring 29 bear against the bottom wall of the installation groove 21 and the sliding element 7 respectively; wherein the limiting groove 22 penetrates a side wall of the installation bracket 2, wherein the pressure element 4 is slidably limited within the limiting groove 22, wherein the limiting structure 9 is provided to slide horizontally on the side wall of the preceding section 11, wherein a second spring 27 is provided between the limiting structure 9 and the preceding section 11, wherein the pressure element 4 bears against the limiting structure 9.

[0037] When the stand is in the unlocked state, the limiting structure 9, together with the sliding element 7, slides downwards into the limiting groove 22. Under the influence of the spring force of the second spring 27, the limiting structure 9 engages in the limiting groove 22 and rests against the pressure element 4. To lock the stand, the user can press the pressure element 4, which pushes the limiting structure 9 out of the limiting groove 22. This compresses the second spring 27 and stores elastic energy, while the sliding element 7, due to the elastic energy of the first spring 29, slides upwards until its upper surface rests against the underside of the locking element 8, thus locking the stand.The interaction of the pressure element 4 and the limiting structure 9 simplifies the steps for locking and unlocking the stand, increasing the work efficiency and user-friendliness of the stand. Example 3:

[0038] With reference to Fig. 6 to Fig. 9 The main difference between this embodiment and the first embodiment is that a connecting column 24 is provided in the center of the installation groove 21, wherein the locking element 8 is fixedly connected to the connecting column 24, wherein the limiting groove 22 penetrates the side wall of the installation bracket 2, and wherein a bearing strip 12 is provided in the center of the sliding element 7, the bearing strip 12 being connected through to the center of the connecting column 24. The stand further comprises a third spring 5, wherein both ends of the third spring 5 bear against a lower surface of the bearing strip 12 and the bottom wall of the installation groove 21, respectively.A first through-groove 26 is formed through the side wall of the connecting column 24, wherein the second through-groove 28 is formed through one side of the sliding element 7, wherein the other end of the drive element 6 successively penetrates the first through-groove 26, the second through-groove 28 and the limiting groove 22, and wherein the drive element 6 bears against an upper surface of the bearing strip 12 to cause the sliding element 7 to slide. One end of the limiting structure 9 is movably confined in the limiting groove 22, and wherein the other end of the limiting structure 9 is slidably connected to the drive element 6.

[0039] Here, the connecting column 24 serves as a support and guide for the sliding element 7, allowing the sliding element 7 to slide stably along the connecting column 24 in the vertical direction, thus ensuring the accuracy of the locking and unlocking operations of the stand. The contact strip 12 penetrates the center of the connecting column 24 and interacts with the drive element 6 and the third spring 5. The drive element 6 rests against the upper surface of the contact strip 12; when the user presses the drive element 6, it can cause the sliding element 7 to slide downwards via the contact strip 12; simultaneously, the contact strip 12 also serves as the point of action for the third spring 5, allowing the third spring 5 to exert an upward spring force on the sliding element 7 via the contact strip 12.The first through-groove 26 and the second through-groove 28 provide a rotational clearance for one end of the drive element 6 and simultaneously limit a rotational range of the drive element 6, so that the drive element 6 rests precisely against the bearing strip 12 and moves it when rotating, thereby ensuring the stability and accuracy of the drive movement of the drive element 6 on the sliding element 7.

[0040] One end of the limiting structure 9 is movably constrained in the limiting groove 22, while the other end is slidably connected to the drive element 6. This connection allows the drive element 6 to rotate the limiting structure 9 simultaneously when it rotates, thereby moving the sliding element 7 downwards. When the stand is unlocked, pressing the drive element 6 engages the limiting structure 9 in the limiting groove 22, thus maintaining the unlocked state of the stand. To lock the stand, pressing the limiting structure 9 causes it to protrude from one end of the drive element 6, thereby releasing the limiting structure 9 from the limiting groove 22.The sliding element 7 is reset upwards under the action of the third spring 5, so that the sliding element 7 can smoothly rest upwards against the underside of the locking element 8 and thus be limited, thereby completing the locking of the stand and ensuring a precise change between the locked and unlocked state of the stand.

[0041] With reference to Fig. 8 and Fig. 9, in a specific embodiment, the limiting structure 9 comprises a limiting block 13 and a fourth spring 14. One end of the limiting block 13 is equipped with a “ a “-shaped limiting section 15 and a deflection groove 16, wherein the limiting section 15 abuts a groove wall of the limiting groove 22; wherein the other end of the limiting block 13 slidably penetrates the drive element 6, wherein the fourth spring 14 is provided in the drive element 6, with both ends of the fourth spring 14 bearing against the limiting block 13 and the drive element 6 respectively.

[0042] The limiting section 15 at one end of the limiting block 13 can rest against the side wall of the limiting groove 22. When the stand is in the unlocked state, the limiting section 15 engages in the limiting groove 22 and is in close contact with the side wall of the limiting groove 22. This structure provides a large contact area and stable support, effectively limiting the position of the sliding element 7 and preventing its unintentional movement, thus ensuring the stability of the stand in the unlocked state. At this point, the other end of the limiting block 13, under the elastic action of the fourth spring 14, penetrates and is limited by an end of the drive element 6 furthest from the connecting column 24.

[0043] To lock the stand, the user presses on the end of the limiting block 13 furthest from the limiting section 15, pushing the limiting section 15 out of the limiting groove 22. This, under the action of the third spring 5, resets the sliding element 7 upwards, so that the sliding element 7 rests against the underside of the locking element 8, thus completing the stand's locking mechanism. At this point, the clearance groove 16 is located within the opening of the limiting groove 22. The clearance groove 16 provides a rotational space for the limiting block 13, reducing interference and jamming of the limiting block 13 during operation. This ensures a smoother locking and unlocking process for the stand, improves the user experience, and allows the user to change the stand's state more easily.

[0044] Furthermore, guide ramps are provided on both opposite sides of the limiting section. When locking or unlocking the stand, the guide ramp 17 can assume a guiding function, thereby ensuring smoother contact between the limiting block 13 and the side wall of the limiting groove 22. As the limiting block 13 approaches the limiting groove 22, the guide ramp 17 facilitates the alignment of the limiting block 13 with the limiting groove 22, allowing the limiting block 13 to engage more smoothly in the limiting groove 22, thus increasing ease of use and efficiency.

Any person skilled in the art in this field will readily think of various equivalent modifications or substitutions within the framework of the technology disclosed in the present application, all of which fall within the scope of protection of the present application.
