Description

Technical Field

[0001] This utility model relates to the field of photographic accessories technology, and in particular to a quick-release base and quick-release assembly with bidirectional press-to-unlock mechanism. Background Technology

[0002] Photography is becoming increasingly widespread in people's daily lives, used to record their experiences. Photography can be done using devices such as mobile phones and cameras. To make photography more convenient, shooting equipment is usually mounted on tripods, shoulder straps, or shoulder straps to produce better results. To allow for quick attachment and detachment of shooting equipment from tripods, shoulder straps, or shoulder straps, quick-release components are often used to indirectly mount the equipment to these devices.

[0003] Quick-release components generally include a quick-release base and a quick-release plate. The quick-release plate is used to connect to the shooting equipment, and the quick-release base is connected to the bracket, shoulder strap, or back strap. Through the quick-release cooperation of the quick-release base and quick-release plate, the shooting equipment can be quickly attached to or detached from the bracket, shoulder strap, or back strap.

[0004] However, existing quick-release mounts typically unlock by pressing an unlock button, usually one or two. In actual use, it is easy to accidentally press the unlock button, causing the quick-release plate to detach and the shooting equipment to fall and be damaged. Therefore, it is necessary to design a corresponding unlocking structure to prevent accidental touches, so as to improve the connection stability and security of the equipment. Utility Model Content

[0005] The primary objective of this invention is to provide a quick-release base and quick-release assembly with bidirectional press-to-unlock mechanism.

[0006] The second objective of this invention is to provide a quick-release assembly having the aforementioned quick-release base.

[0007] To achieve the first objective of this utility model, it provides a quick-release base for bidirectional press-to-unlock, comprising a housing, a locking block, a locking elastic element, a first pressing block, a second pressing block, and a reset elastic component. The housing has a receiving cavity, and its outer end face has a quick-release groove. A fixing block and a through groove are provided around the outer periphery of the quick-release groove on the outer end face, the through groove communicating with the receiving cavity. The housing has a first sliding groove and a second sliding groove extending through both sides in the pressing direction, communicating with the receiving cavity. The locking block is movably disposed within the receiving cavity. A free locking block is provided at the through groove of the locking block. The locking elastic element is connected to the locking block, and applies an elastic force based on the outward orientation of the through groove to the free locking block. The first pressing... The first pressing block is set in the first slide groove. The first pressing block has a first pressing drive end at the outer end of the first slide groove and an inclined driving end at the inner end of the first pressing block. The second pressing block is set in the second slide groove. The second pressing block has a second pressing drive end at the outer end of the second slide groove and a driving block is hinged to the inner end of the second pressing block. The reset elastic component drives the first pressing block and the second pressing block to exert an elastic force in opposite directions and outwards. In the unlocked state, the first pressing block and the second pressing block move towards each other along the pressing direction. The inclined driving end cooperates with the inclined surface of the driving block and drives the driving block to move towards the back side. The driving block drives the locking block to move towards the back side. The free block moves inwards at the through groove.

[0008] As can be seen from the above scheme, the quick-release slot is used to install the quick-release block, and the quick-release block is clamped and positioned by the fixed block and the movable free block. Thus, while ensuring efficient clamping and fixing force, when unlocking, the first pressing block and the second pressing block need to be pressed simultaneously to drive the drive block to move to the back side, which in turn drives the free block to move to the back side and separate from the quick-release block, so that the quick-release block can be separated from the quick-release slot. When the first pressing block or the second pressing block is pressed on only one side, the free block cannot be moved to the back side. Therefore, the problem of unlocking and disengagement caused by accidental touch or press on one side is avoided, thereby improving the clamping stability and safety of the quick-release seat.

[0009] A further proposed solution is that the locking block is provided with a first hinge axis, which is parallel to the pressing direction and hinged to the outer shell, and the locking block rotates around the first hinge axis.

[0010] As can be seen from the above, the arrangement of the first hinge shaft enables the locking block to rotate stably, thereby enabling the self-locking block to extend or retract stably at the through slot.

[0011] A further solution is to provide a drive groove between the free block and the first hinge shaft in the locking block. The drive groove runs through the pressing direction, and the inclined drive end cooperates with the drive block in the inclined surface of the drive groove. The drive block drives the bottom wall of the drive groove to move towards the back side.

[0012] As can be seen from the above, the sliding engagement between the hinged rotating drive block and the inclined drive end makes the drive block move more smoothly and with a greater range of motion on the front and back sides of the receiving cavity, which in turn helps to reduce the thickness of the outer shell without affecting the telescopic movement range of the free block.

[0013] A further embodiment is that the reset elastic component includes a first spring and a second spring arranged along the pressing direction, with the first spring abutting between the first pressing block and the housing, and the second spring abutting between the second pressing block and the housing.

[0014] As can be seen above, by having two springs elastically abut against the pressing block respectively, the pressing block is provided with elastic restoring force, enabling it to independently return to its original position, further preventing accidental touch and mis-locking.

[0015] A further embodiment is that the first pressing block is provided with a first positioning groove along the pressing direction, the outer shell is provided with a first positioning baffle in the first positioning groove, and the first spring is provided in the first positioning groove, with the first spring abutting between the first positioning baffle and the first pressing block; the second pressing block is provided with a second positioning groove along the pressing direction, the outer shell is provided with a second positioning baffle in the second positioning groove, and the second spring is provided in the second positioning groove, with the second spring abutting between the second positioning baffle and the second pressing block.

[0016] As can be seen from the above, the arrangement of the positioning groove and the positioning baffle stabilizes the installation of the spring and provides stable support for the spring's elastic reset.

[0017] A further proposed solution is that the outer casing includes a base and a back cover. The base has a receiving cavity, and the back cover covers the receiving cavity and connects to the base. The fixing block, the through groove, the first slide groove, and the second slide groove are all provided on the base. The locking elastic element abuts between the locking block and the back cover.

[0018] As can be seen from the above, the arrangement of the base and the back cover facilitates the arrangement and installation of components such as the locking block, the locking elastic element, the first pressing block, and the second pressing block.

[0019] A further proposed solution is to have a roller at the end of the drive block facing the inclined drive end, with the inclined drive end and the roller rolling in a rolling engagement.

[0020] As can be seen from the above, the rollers and the inclined plane of the drive end roll together, enabling the drive block to move more smoothly, thereby driving the extension or retraction of the free block.

[0021] A further improvement is to make the roller's rolling axis perpendicular to the pressing direction.

[0022] As can be seen above, the drive block can move stably by making the rolling axis perpendicular to the pressing direction.

[0023] A further proposed solution is that the drive block has a second hinge shaft at the end facing the second pressing drive end, the second hinge shaft is hinged to the second pressing block, and the second hinge shaft is perpendicular to the pressing direction.

[0024] As can be seen from the above, the second hinge axis is perpendicular to the pressing direction, which enables the drive block to rotate stably around the second hinge axis.

[0025] To achieve the second objective of this utility model, this utility model provides a quick-release assembly, including a quick-release base and a quick-release plate as described above. The quick-release plate is installed in a quick-release groove, and a fixed block and a free block limit the movement of the quick-release plate.

[0026] As can be seen from the above scheme, by installing the quick-release plate in the quick-release slot, the fixed block and the free block limit the quick-release plate. When unlocking, the first pressing block and the second pressing block need to be pressed simultaneously to drive the driving block to move to the back side, which in turn drives the free block to move to the back side and separate from the quick-release plate, so that the quick-release plate can be separated from the quick-release slot. When the first pressing block or the second pressing block is pressed on only one side, the free block cannot move to the back side. Therefore, the problem of unlocking and disengagement caused by accidental touch or press on one side is avoided, thereby improving the clamping stability and safety of the quick-release seat.

[0036] The present invention will be further described below with reference to the accompanying drawings and embodiments. Detailed Implementation

[0037] Reference Figures 1 to 9 The quick-release base includes a housing 1, a locking block 13, a locking elastic element 132, a first pressing block 14, a second pressing block 15, and a reset elastic assembly. The housing 1 includes a base body 11 and a back cover 12. The base body 11 is provided with a receiving cavity 114. The back cover 12 covers the receiving cavity 114 and is connected to the base body 11. The receiving cavity 114 is provided inside the base body 11. A quick-release groove 111 is provided on the outer end face of the base body 11. Three fixing points are provided on the outer periphery of the quick-release groove 111 on the outer end face of the base body 11. The housing 1 has a locking block 112 and a through groove 113, the through groove 113 is connected to the receiving cavity 114, one of the locking blocks 112 is located on the bottom side, the two locking blocks 112 are located on both sides of the pressing direction X, the through groove 113 is located on the top, and the housing 1 has a first sliding groove 115 and a second sliding groove 116 through the housing 1 on both sides of the pressing direction X. The first sliding groove 115 and the second sliding groove 116 both extend along the pressing direction X and are connected to the receiving cavity 114.

[0038] The locking block 13 is movably disposed within the receiving cavity 114. The locking block 13 has a first hinge shaft 136 at its bottom 135 and a free locking block 131 at its top. The locking block 13 has a drive groove 134 between the free locking block 131 and the first hinge shaft 136, and a positioning groove 133 between the free locking block 131 and the drive groove 134. The back cover 12 has a fixing block 123 at its bottom. The first hinge shaft 136 is parallel to the pressing direction X and is hinged to the fixing block 123. The locking block 13 rotates around the first hinge shaft 136. The drive groove 134 passes through the back cover 12 along the pressing direction X. The back cover 12 has a first positioning baffle 121 and a second positioning baffle 122. The first positioning baffle 121 and the second positioning baffle 122 are arranged along the pressing direction X and located on both sides of the drive groove 134.

[0039] The back cover 1 has a positioning post 124 in the positioning groove 133. The positioning post 124 is covered with a locking elastic member 132. The locking elastic member 132 is a spring. The locking elastic member 132 abuts between the locking block 13 and the back cover 1. The locking elastic member 132 applies an elastic force to the free block 131 based on the outward opening of the through groove 113. The free block 131 is located at the through groove 113 and can extend or retract relative to the through groove 113.

[0040] The first pressing block 14 is disposed in the first slide groove 115. The first pressing block 14 has a first pressing drive end 143 at the outer end of the first slide groove 115 and an inclined drive end 141 at the inner end of the first pressing block 14. The inclined drive end 141 faces the back cover 1 and the back side of the inclined drive end 141 is arranged in a planar manner. The first pressing block 14 has a first positioning groove 142 along the pressing direction X. The reset elastic component includes a first spring 21 and a second spring 22 arranged along the pressing direction X respectively. The first spring 21 is disposed in the first positioning groove 142. The first positioning baffle 121 is located in the first positioning groove 142. The first spring 21 abuts between the first positioning baffle 121 and the first pressing block 14. The first spring 21 applies an outward elastic force to the first pressing block 14.

[0041] The second pressing block 15 is disposed in the second slide groove 116. The second pressing block 15 has a second pressing drive end 153 at the outer end of the second slide groove 116. The second pressing block 15 has a drive block 16 hinged to the inner end of the second slide groove 116. The second pressing block 15 has a second positioning groove 151 along the pressing direction X. The second spring 22 is disposed in the second positioning groove 151. The second positioning baffle 122 is located in the second positioning groove 151. The second spring 22 abuts between the second positioning baffle 122 and the second pressing block 15. The second spring 22 applies an outward elastic force to the second pressing block 15, thereby resetting the elastic component to realize the driving force of the first pressing block 14 and the second pressing block 15 in opposite directions and outward.

[0042] The drive block 16 has a roller 17 at the end facing the inclined drive end 141. The rolling axis 171 of the roller 17 is perpendicular to the pressing direction X. The roller 17 is hinged to the end of the drive block 16 via a rolling shaft. The end of the drive block 16 facing the second pressing drive end 153 is located in the second positioning baffle 122 and has a second hinge shaft 162. The second hinge shaft 162 is hinged to the second pressing block 15 and is perpendicular to the pressing direction X. The inclined drive end 141 and the roller 17 of the drive block 16 are inclinedly engaged in the drive groove 134. The quick-release groove 111, the inclined drive end 141, the roller 17 and the bottom wall of the drive groove 134 are arranged sequentially from the front to the rear.

[0043] The quick-release assembly includes a quick-release base and a quick-release plate as described above. The quick-release plate is used to connect photographic equipment. In the locked state, the quick-release plate is installed in the quick-release slot 111. Multiple fixed blocks 112 and free blocks 131 limit the quick-release plate and provide a forward elastic force to the locking block 13 through the locking elastic element 132, thereby increasing the locking force of the free blocks 131.

[0044] Reference Figure 7-9In the unlocked state, driven by external force, the first pressing block 14 and the second pressing block 15 move towards each other along the pressing direction X. The inclined driving end 141 cooperates with the inclined surface of the driving block 16 and drives the driving block 16 to move towards the back side. The driving block 16 drives the locking block 13 to move towards the back side. The free locking block 131 moves inward at the through groove 113. Then the free locking block 131 separates from the quick-release plate, and the quick-release plate can smoothly disengage from the quick-release seat.

[0045] When a mis-touch occurs, i.e. when the first or second pressing block is driven on one side, the free block cannot move to the back side. Therefore, the problem of unlocking and disengagement caused by a mis-touch or mis-press on one side is avoided, thereby improving the clamping stability and safety of the quick-release seat.

[0046] Of course, the above embodiments are only preferred embodiments of this case. In specific applications, there can be more variations. For example, the reset elastic component can take many forms, such as using a spring to reset the two pressing blocks outward at the same time, or using a torsion spring or a tension spring, all of which can achieve the reset of the pressing blocks. Alternatively, the locking elastic component can also use different types of springs, torsion springs, or tension springs, all of which can achieve the reset of the locking block. In addition to using a hinged rotation method, the movement of the locking block can also be achieved by using a sliding movement method to realize the extension or retraction of the free locking block 131. Therefore, all of the above changes fall within the protection scope of this utility model.
