For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0038] First embodiment

[0039] refer to Figure 1The utility model provides a quick-release seat 1, which is used to install a quick-release plate to achieve the installation and fixation of the quick-release plate. At this time, a shooting device is installed on the quick-release plate. Specifically, the shooting device is connected to the quick-release plate by threads. It can be understood that in other embodiments, the shooting device can also be installed on the quick-release plate by the cooperation of a cold shoe block and a cold shoe slot. Among them, the shooting device can be but not limited to a camera, a video camera, a smart phone, etc.

[0040] refer to Figure 1 and Figure 2 The quick-release seat 1 includes a seat body 11, a clamping assembly 12 and a driving assembly 13. The seat body 11 is provided with a slide groove 101. The slide groove 101 is provided with an installation opening 102. The quick-release plate is installed in the slide groove 101 through the installation opening 102. The clamping assembly 12 is movably provided on the seat body 11 and can limit the quick-release plate from being separated from the slide groove 101. The driving assembly 13 is movably provided on the seat body 11. When the driving assembly 13 is pressed, the driving assembly 13 drives the clamping assembly 12 to release the restriction on the quick-release plate. The length extension direction of the slide groove 101 is defined as the first direction 103 ( Figure 1 As shown), the first direction 103 is the assembly direction of the quick-release plate in the slide slot, and the width direction of the slide slot 101 is the second direction 104 ( Figure 1 shown).

[0041] It should be noted that, in the present embodiment, the slide groove 101 is specifically a dovetail groove. It is understandable that, in other embodiments, the slide groove 101 may not be a dovetail groove. In this case, the slide groove 101 can be used to install a quick-release plate.

[0042] Continue to refer Figure 2 The seat body 11 is provided with three limit blocks 105, the three limit blocks 105 protrude from the surface of the seat body 11, and the three limit blocks 105 are arranged at intervals along the circumference of the seat body 11. Two of the three limit blocks 105 are arranged opposite to each other, and the other limit block 105 is located between the two limit blocks 105. The three limit blocks 105 enclose a slide groove 101, and an installation opening 102 is formed between the two limit blocks 105.

[0043] Continue to refer Figure 2 The seat body 11 is provided with a first through hole 106 and a second through hole 107 , and the first through hole 106 and the second through hole 107 are spaced apart in the first direction 103 .

[0044] Continue to refer Figure 2The seat body 11 includes a first plate body 108 and a second plate body 109. The first plate body 108 is provided with three stop blocks 105, a first through hole 106 and a second through hole 107. The second plate body 109 covers the clamping assembly 12 and the driving assembly 13 between the first plate body 108 and the second plate body 109. The second plate body 109 is detachably connected to the first plate body 108. Since the first plate body 108 and the second plate body 109 are detachably connected, the installation and removal of the clamping assembly 12 and the driving assembly 13 are convenient. It can be understood that in other embodiments, the seat body 11 can also be an integrally formed structure.

[0045] Continue to refer Figure 2 The clamping assembly 12 includes two clamping members 129, which are movably disposed at both ends of the base body 11 and are independently disposed. The two clamping members 129 extend out of the slide slot 101 through the first through hole 106 and the second through hole 107, respectively. The two clamping members 129 are arranged at intervals in the first direction 103. The two clamping members 129 lock the quick-release plate to prevent the quick-release plate from leaving the slide slot 101. Alternatively, the two clamping members 129 can also be arranged at intervals in the second direction 104.

[0046] Among them, one of the two clamping members 129 is clamped on the quick-release plate, and the other is against the quick-release plate, so as to lock the quick-release plate, that is, to limit the quick-release plate from being separated from the mounting opening 102 and the slide slot 101. It can be understood that in other embodiments, both clamping members 129 are clamped on the quick-release plate, or both clamping members 129 are against the quick-release plate.

[0047] In order to realize the release of the restriction on the quick-release plate by driving the two clamping members 129 separately, in one embodiment, the driving assembly 13 includes two driving members 130, which are movably arranged at the two ends of the seat body 11 and are independently arranged. The two driving members 130 are in the second direction 104, and each driving member 130 drives a corresponding clamping member 129. When unlocking the quick-release plate, the two driving members 130 are pressed at the same time, and the two driving members 130 drive the two clamping members 129 to retract the seat body 11 to release the restriction on the quick-release plate. Among them, both clamping members 129 need to release the restriction on the quick-release plate before the quick-release plate can be removed, otherwise the restriction on the quick-release plate cannot be released, which avoids the accidental unlocking of the quick-release plate due to the accidental touching of one of the driving members 130, and improves the stability of the installation.

[0048] Figure 2 It is shown that the two clamping members 129 are in the first direction 103 and the two driving members 130 are in the second direction 104. It is understood that in other embodiments, the two clamping members 129 and the two driving members 130 are in the first direction 103 or the second direction 104 at the same time.

[0049] It should be noted that in other embodiments, the number of the clamping components 129 is multiple, the number of the driving components 130 is also multiple, and the number of the clamping components 129 corresponds to the number of the driving components 130, or the number of the clamping components 129 and the number of the driving components 130 are set according to actual needs, and the setting method of the multiple clamping components 129 and the multiple driving components 130 is the same as the above-mentioned setting method. At this time, the multiple clamping components 129 are required to release the restrictions on the quick-release plate so that the quick-release plate can be disassembled.

[0050] In order to realize the automatic reset of the driving member 130, in one embodiment, the quick-release seat 1 includes a first elastic member 14, and the two ends of the first elastic member 14 are respectively in contact with the seat body 11 and the driving member 130. When the driving member 130 is pressed, the driving member 130 overcomes the elastic force of the first elastic member 14 to move relative to the seat body 11 and drive the clamping member 129 to retract into the seat body 11. At this time, the first elastic member 14 is compressed and accumulates the reset elastic force. When the driving member 130 is released from being pressed, the first elastic member 14 releases the reset elastic force to drive the driving member 130 to move in the opposite direction and reset. Among them, the number of the first elastic members 14 corresponds to the number of the clamping members 129, that is, there are two first elastic members 14 and they correspond to two clamping members 130 respectively.

[0051] The driving member 130 includes a driving block 117 and a button 118. The driving block 117 is movably disposed in the base 11. The opposite ends of the driving block 117 are respectively abutted against the clamping member and the button 118. The button 118 is movably disposed in the base 11 and protrudes from the base 11. The first elastic member is respectively abutted against the driving block 117 and the base 11. When the button 118 is pressed, the button 118 moves relative to the base 11. The button 118 drives the driving block 117 to move relative to the base 11. The first elastic member 14 is compressed to accumulate elastic force. Under the action of the driving force, the driving block 117 drives the clamping member 129 to retract into the base 11. At this time, the clamping member 129 releases the clamping restriction on the quick-release plate. The moving direction of the button 118 is perpendicular to the moving direction of the driving block 117, and the moving direction of the button 118 is parallel to the second direction 104. The moving direction of the driving block 117 is parallel to the first direction 103.

[0052] refer to Figure 3, the ends of the driving block 117 and the button 118 that contact each other are both provided with a first inclined surface 119, the first inclined surface 119 is inclined to the moving direction of the button 118, and the two first inclined surfaces 119 abut against each other. When the button 118 is pressed, the two first inclined surfaces 119 move relative to each other, and drive the driving block 117 to move relative to the seat body 11, and the driving block 117 drives the clamping member 129 to retract the seat body 11. By providing the first inclined surface 119, the first inclined surface 119 can reduce the contact resistance between the button 118 and the driving block 117, making it convenient for the user to operate the button 118. It can be understood that in other embodiments, the end of the button 118 is provided with the first inclined surface 119, and the end of the driving block 117 is not provided with the first inclined surface 119; or the end of the button 118 is not provided with the first inclined surface 119, and the end of the driving block 117 is provided with the first inclined surface 119. Alternatively, the ends of the button 118 and the driving block 117 that contact each other are not provided with the first inclined surface 119 . In this case, the end of the button 118 can directly abut against the end of the driving block 117 .

[0053] It should be noted that the two driving blocks 117 are on the same straight line. When they are driven by the two buttons 118 respectively, the two driving blocks 117 are close to each other, otherwise the two driving blocks 117 are far away from each other. The two buttons 118 are on the same straight line. When pressed, the two buttons 118 are close to each other, otherwise the two buttons 118 are far away from each other. Since the two buttons 118 are on the same straight line, the user can operate the two buttons 118 at the same time with one hand, which is convenient for the user to operate.

[0054] refer to Figure 4 The clamping member 129 includes an inclined block 131 and a second elastic member 16. The inclined block 131 is movably disposed on the seat 11 and abuts against the driving member 130. The opposite ends of the second elastic member 16 elastically abut against the inclined block 131 and the seat 11, respectively. The second elastic member 16 drives the inclined block 131 to extend out of the slide slot. When the button 118 is pressed, the button 118 drives the driving block 117 to drive the inclined block 131 to retract into the seat 11. At this time, the second elastic member 16 is compressed to accumulate elastic force. When the button 118 is pressed, the second elastic member 16 releases the elastic force to drive the driving block 117 to move in the opposite direction and reset. At the same time, the driving block 117 also drives the button 118 to move in the opposite direction and reset.

[0055] refer to Figure 3The ends of the inclined block 131 and the driving member 130 that contact each other are both provided with a second inclined surface 120, and the second inclined surface 120 is inclined in the moving direction of the clamping member 129. The two second inclined surfaces 120 abut against each other. When the driving block 117 is driven by the button 118, the two second inclined surfaces 120 move relative to each other and drive the inclined block 131 to move relative to the seat body 11 and retract into the seat body 11. The second inclined surface 120 can reduce the contact resistance between the driving block 117 and the clamping member 129, so that the driving block 117 can better drive the inclined block 131 to move. In this embodiment, the driving block 117 is provided with an avoidance gap, and the inclined block 131 is located in the avoidance gap. At this time, the driving block 117 abuts against the opposite sides of the inclined block 131 respectively, so that the force on the inclined block 131 is more balanced, and when the driving block 117 is pushed, the driving block 117 moves along the second inclined surface 120 to push the inclined block 131 to retract.

[0056] In this embodiment, the ends of the inclined block 131 and the driving block 117 that contact each other are both provided with the second inclined surface 120. It can be understood that in other embodiments, the end of the driving block 117 is provided with the second inclined surface 120, and the end of the inclined block 131 is not provided with the second inclined surface 120; or the end of the driving block 117 is not provided with the second inclined surface 120, and the end of the inclined block 131 is provided with the second inclined surface 120. Alternatively, the ends of the driving block 117 and the inclined block 131 that contact each other are not provided with the second inclined surface 120, in which case, the end of the driving block 117 directly abuts against the end of the inclined block 131.

[0057] The end of the inclined block 131 is provided with a notch groove 112 . When the clamping piece 129 extends out of the slide slot 101 , the quick-release plate is clamped in the notch groove 112 , and the end of the inclined block 131 is clamped in the quick-release plate to restrict the quick-release plate from sliding out of the slide slot 101 from the installation opening 102 .

[0058] The end of the inclined block 131 is provided with a third inclined surface 125, which is inclined in the first direction 103, and faces the side where the installation port 102 is located, and the third inclined surface 125 is in the assembly direction of the quick-release plate. When the quick-release plate is installed in the slide slot 101, the quick-release plate abuts against the fourth inclined surface 125, and under the pressure of the quick-release plate, the inclined block 131 overcomes the return elastic force released by the second elastic member 16 to retract the seat body 11. Since the end of the inclined block 131 is provided with the third inclined surface 125, the resistance between the quick-release plate and the inclined block 131 is small, which is convenient for users to operate the quick-release plate.

[0059] refer to Figure 5The quick-release seat also includes a third elastic member 19, which is respectively in contact with the button 118 and the seat body 11. When the button 118 is pressed, the button 118 overcomes the elasticity of the third elastic member 19 and moves relative to the seat body 11. At the same time, the button 118 drives the driving block 117 to move relative to the seat body 11. At this time, the third elastic member 19 is compressed and accumulates a resetting elastic force. When the button 118 is released, the third elastic member 19 releases the resetting elastic force to drive the button 118 to reset, and the button 118 is clamped on the inner wall of the seat body 11 to limit the button 118 from being separated from the seat body 11 in the moving direction of the button 118.

[0060] refer to Figure 6 and Figure 7 The utility model also provides a quick-release assembly 2, which includes the quick-release seat 1 and the quick-release plate 3. The quick-release plate 3 is installed in the slide slot 101 through the installation opening 102, and the clamping member 129 is clamped on the quick-release plate 3 to restrict the quick-release plate 3 in the slide slot 101. Pressing the two driving members 130 at the same time makes the two clamping members 129 release the restriction on the quick-release plate 3 at the same time, and the quick-release plate 3 is separated from the slide slot 101 from the installation opening 102 to realize the removal of the quick-release plate 3. Figure 7 It is shown that a threaded rod is provided on the quick release plate 3, and the camera device can be threadedly connected with the threaded rod to fix the camera device on the quick release plate. It can be understood that in other embodiments, the quick release plate 3 may not be provided with a threaded rod, and in this case, a quick release interface such as a cold shoe slot or a cold shoe block may be provided on the quick release plate.

[0061] The quick-release plate 3 is provided with a fourth inclined surface 128 on the side facing the quick-release seat 1. The fourth inclined surface 128 is inclined to the assembly direction of the quick-release plate 3, that is, the fourth inclined surface 128 is inclined to the first direction 103, and the fourth inclined surface 128 is biased away from the side where the quick-release seat 1 is located. When the quick-release plate 3 is installed in the slide slot 101 through the installation opening 102, the clamping member 129 abuts against the fourth inclined surface 128 and moves along the fourth inclined surface 128, so that the quick-release plate 3 drives the clamping member 129 to retract into the seat body 11, so that the quick-release plate 3 passes over the clamping member 129 and is completely stored in the slide slot 101, and then the clamping member 129 extends out of the slide slot 101 under the action of elastic force and is clamped to the quick-release plate 3, so as to achieve the locking of the quick-release plate 3. Since the quick-release plate 3 is provided with the fourth inclined surface 128, the contact resistance between the quick-release plate 3 and the clamping member 129 can be effectively reduced, and the quick-release plate 3 can be conveniently installed in the slide slot 101. The number of the fourth inclined surfaces 128 is set to be multiple, and the multiple fourth inclined surfaces 128 are arranged at intervals along the circumference of the quick-release plate 3, so that the contact resistance between the quick-release plate 3 and the clamping member 129 can be reduced when the quick-release plate 3 slides into the slide slot 101 in any direction.

[0062] Second embodiment

[0063] refer to Figure 8 The structure of the quick-release seat 1 of this embodiment is basically the same as that of the quick-release seat 1 of the first embodiment, except that the arrangement type of the clamping member 129 is different. Figure 8 The driving member 130 is provided with a groove 124, and the clamping member 129 includes a roller 132, and the axial direction of the roller 132 is parallel to the second direction 104. The roller 132 is accommodated in the groove 124. When the driving member 130 is pressed and the driving block 117 moves relative to the seat body 11, the groove wall of the groove 124 abuts against the roller 132, so that the driving block 117 drives the roller 132 to move relative to the seat body 11 and retract into the seat body 11. When the driving block 117 moves in the opposite direction relative to the seat body 11, the other groove wall of the groove 124 abuts against the roller 132, so that the driving member 130 drives the roller 132 to extend out of the slide slot 101.

[0064] The roller 132 includes a first rolling cylinder 113 and two second rolling cylinders 114. The two second rolling cylinders 114 are respectively disposed at opposite ends of the first rolling cylinder 113. The radial dimension of the second rolling cylinder 114 is smaller than the radial dimension of the first rolling cylinder 113. It can be understood that in other embodiments, the roller 132 can also be a cylinder with the same diameter.

[0065] refer to Fig. 9 and Fig.10 The seat body 11 is provided with a wedge block 17, and the wedge block 17 is provided with a fifth inclined surface 133. The fifth inclined surface 133 is inclined in the direction of the plane where the first direction 103 and the second direction 104 are located, and the roller 132 abuts against the fifth inclined surface 133. When the button 118 is pressed, the button 118 drives the driving block 117 to overcome the elastic force of the second elastic member 16 to move relative to the seat body 11, and the groove wall of the groove 124 abuts against the roller 132, so that the driving block 117 drives the roller 132 to move along the fifth inclined surface 133 and retract into the seat body 11. When the button 118 is released from being pressed, the second elastic member 16 releases the restoring elastic force to drive the driving block 117 to move in the opposite direction, and at the same time, the other groove wall of the groove 124 abuts against the roller 132, so that the driving block 117 drives the roller 132 to move in the opposite direction along the fifth inclined surface 133 and extend out of the slide slot 101. Due to the fifth inclined surface 133, the roller 132 is moved along a plane inclined to the first direction 103 and the second direction 104 to extend and retract the seat body 11. Specifically, the wedge block 17 is disposed on the second plate body 109, and the first rolling cylinder 113 abuts against the fifth inclined surface 133. It can be understood that in other embodiments, the wedge block 17 can also be disposed on the first plate body 108.

[0066] It should be noted that, in this embodiment, the number of wedge blocks 17 is set to two, the two wedge blocks 17 are spaced apart in the second direction 104, a sliding channel 21 is formed between the two wedge blocks 17, the end of the driving block 117 is received in the sliding channel 21, and the driving block 117 can move along the sliding channel 21.

[0067] It should be noted that the quick-release seat 1 includes two blocking blocks 18, which are spaced apart in the seat body 11 in the second direction 104. The two blocking blocks 18 and two wedge blocks 17 are spaced apart in the second direction 104, and the two wedge blocks 17 are located between the two blocking blocks 18. The blocking block 18 is provided with a sixth inclined surface 134, which is inclined to the plane where the first direction 103 and the second direction 104 are located. The two second rolling cylinders 114 are respectively in contact with the sixth inclined surface 134. When the first rolling cylinder 113 moves along the fifth inclined surface 133, the two second rolling cylinders 114 also move along the sixth inclined surface 134. At this time, the roller 132 is restricted between the fifth inclined surface 133 and the sixth inclined surface 134, allowing the roller 132 to move smoothly. The first rolling cylinder 113 is located between the two blocking blocks 18 . The two blocking blocks 18 are located at opposite sides of the first rolling cylinder 113 . The two sixth inclined surfaces 134 abut against the two second rolling cylinders 114 to limit the roller 132 from moving in the axial direction.

[0068] Third embodiment

[0069] refer to Figure 1 The structure of the quick-release seat 1 of this embodiment is basically the same as that of the quick-release seat 1 of the first embodiment, except that the arrangement type of the clamping member 129 is different.

[0070] The two clips 129 are defined as a first clip 110 and a second clip 111, the first clip 110 is far away from the installation opening 102, and the second clip 111 is close to the installation opening 102. The first clip 110 and the second clip 111 extend out of the slide slot 101 through the first through hole 106 and the second through hole 107 respectively, and the first clip 110 moves in a direction perpendicular to the plane where the first direction 103 and the second direction 104 are located and extends out of the slide slot 101, and the second clip 111 moves in a direction inclined to the plane where the first direction 103 and the second direction 104 are located and extends out of the slide slot 101, so that the quick release plate 3 is subjected to both lateral and longitudinal forces at the same time, making the quick release plate 3 more stably installed.

[0071] One of the first clamping member 110 and the second clamping member 111 is the inclined block 131 and the second elastic member 16 , and the other is the roller 132 . The driving member 130 is provided with a groove 124 matched with the roller 132 . Figure 2The first clamping member 110 is shown as a slanted block 131 and a second elastic member 16, the second clamping member 111 is a roller 132, and the axial direction of the second clamping member 111 is parallel to the second direction 104. It can be understood that in other embodiments, the first clamping member 110 is a roller 132, and the second clamping member 111 is a slanted block 131 and a second elastic member 16.

[0072] It should be noted that, in this embodiment, when the quick-release plate 3 is installed in the slide slot 101 through the installation opening 102, the first clamping member 110 is clamped on the quick-release plate 3, and the second clamping member 111 is abutted against the quick-release plate 3, so as to restrict the quick-release plate 3 in the slide slot 101. The two driving members 130 are pressed simultaneously, so that the first clamping member 110 and the second clamping member 111 simultaneously release the restriction on the quick-release plate 3, and the quick-release plate 3 is separated from the slide slot 101 from the installation opening 102, so as to realize the removal of the quick-release plate 3.
