Description

Technical Field

[0001] The utility model relates to the technical field of photographic equipment, in particular to a quick-detachable assembly head. Background Art

[0002] A pan head is a device for placing and supporting photographic equipment. The existing pan head includes a base and a connecting seat connected to the base. The base is used to connect to the support frame, and the connecting seat is used to connect to the photographic equipment. In order to facilitate the installation of the photographic equipment on the connecting seat, the connecting seat and the base are connected in a detachable manner. Specifically, the base is provided with an assembly groove for the lower end of the connecting seat to be inserted and a connecting hole connected to the assembly groove. The base is threadedly connected to a screw in the connecting hole. The connecting seat and the base are fixed by rotating the screw so that the screw stops on the connecting seat, and the connecting seat is released by rotating the screw so that the screw is separated from the connecting seat. Since the detachable connection structure between the connecting seat and the base achieves the fixing and release of the connecting seat by rotating the screw, when the connecting seat is placed in the assembly hole, one hand needs to hold the photographic equipment, and the other hand needs to rotate the screw at the same time. The operation is very inconvenient and easily causes the photographic equipment to tilt. Utility Model Content

[0003] The utility model aims to provide a quick-detachable assembly pan head to solve the problem that in the existing pan heads, the connection seat and the base are fixed and released by rotating a screw rod, and both hands are required for assembly, which is very inconvenient.

[0005] The quick-detachable assembly pan-tilt platform comprises a base and a connecting seat, the base comprising a base shell, a driving block, a locking block and an inner stop block, the driving block can move forward and backward along the base shell to make the locking block move in the left and right directions along the base shell to a locking position and an unlocking position, the base shell has an assembly surface for placing the connecting seat, when the locking block moves to the locking position, it cooperates with the assembly surface to limit the connecting seat from moving away from the base, and when the locking block moves to the unlocking position, it releases the connecting seat. The locking blocks are two, and the two locking blocks are opposite to each other on the driving block. The inner stop block can move up and down along the base shell to extend out or retract the assembly surface, and when the driving block drives the locking block to move to the unlocking position, the inner stop block moves upward and extends out of the assembly surface to abut against the driving block front and back to limit the movement of the driving block, and when the inner stop block moves downward and retracts the assembly surface, it releases the driving block so that the driving block drives the locking block to move to the locking position.

[0006] Furthermore, one of the locking block and the driving block is provided with a guide hole, and the other of the two is provided with a guide column slidably matched with the guide hole. When the driving block moves forward and backward, the guide column moves along the guide hole to make the locking block move left and right.

[0009] Furthermore, the driving block is provided with an outer stop block that can move left and right along the driving block, and the base shell has an exposed opening for the outer stop block to move out of the base shell. When the driving block drives the locking block to move to the locking position, the outer stop block moves out of the base shell from the exposed opening and moves away from the driving block, so that the outer stop block and the driving block are staggered left and right and abut against the outer wall of the base shell.

[0010] Furthermore, the outer stop block is slidably connected to the driving block, the outer stop block has an outer stop cavity, the driving block is provided with a connecting rod extending into the outer stop cavity, and the outer stop cavity is provided with a second elastic member with one end resting on the connecting rod and the other end resting on the wall of the outer stop cavity.

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] Example: Figure 1-9As shown, the quick-detachable assembly pan-tilt head includes a base 1 and a connecting seat 2, the base 1 includes a base shell 101, a driving block 102, a locking block 103 and an inner stop block 104, the driving block 102 can move forward and backward along the base shell 101 to make the locking block 103 move to a locking position and an unlocking position along the base shell 101 in the left and right direction, the base shell 101 has an assembly surface 105 for placing the connecting seat 2, when the locking block 103 moves to the locking position, it cooperates with the assembly surface 105 to form a locking groove 106, the locking groove 106 is inserted and cooperated with the connecting seat 2 to limit the connecting seat 2 from moving away from the base 1, and ... When the block 103 moves to the unlocking position, the connecting seat 2 is released. There are two locking blocks 103, and the two locking blocks 103 are opposite to each other on the driving block 102. The inner stop block 104 can move up and down along the base shell 101 to extend out or retract into the assembly surface 105. When the driving block 102 drives the locking block 103 to move to the unlocking position, the inner stop block 104 moves up and extends out of the assembly surface 105, and the driving block 102 is abutted against the front and back to limit the movement of the driving block 102. When the inner stop block 104 moves down and retracts into the assembly surface 105, the driving block 102 is released, so that the driving block 102 drives the locking block 103 to move to the locking position. For the convenience of description, when the locking block 103 moves to the locking position, the position of the driving block 102 is defined as the rear stop position, and when the locking block 103 moves to the unlocking position, the position of the driving block 102 is defined as the front stop position, the front stop position is close to the front, and the rear stop position is close to the rear, that is, when the driving block 102 moves forward relative to the base shell 101, it drives the locking block 103 to the unlocking position, and when the driving block 102 moves backward relative to the base shell 101, it drives the locking block 103 to the locking position.

[0029] When the connecting seat 2 is detached from the base 1, the connection state between the base 1 and the connecting seat 2 is defined as a detached state. In the detached state, the inner stop block 104 extends out of the assembly surface 105 and abuts against the driving block 102 front and back to limit the driving block 102 from moving away from the front stop position (that is, the driving block 102 is limited to the front stop position). When the driving block 102 is in the front stop position, the locking block 103 is in the unlocking position.

[0030] When the connecting seat 2 is connected to the base 1, the connection state of the base 1 and the connecting seat 2 is defined as an assembly state. In the assembly state, the connecting seat 2 abuts against the assembly surface 105, causing the inner stop block 104 to move downward and retract into the assembly surface 105 to release the driving block 102, and then the driving block 102 drives the locking block 103 to move to the locking position. When the locking block 103 moves to the locking position, it cooperates with the assembly surface 105 to form a locking groove 106, thereby realizing the locking of the connecting seat 2.

[0031] As can be seen from the above, the quick-detachable assembly pan-tilt head can achieve the connection between the connection base 2 and the base 1 by simply placing the connection base 2 on the assembly surface 105 of the base 1. The connection is quick and convenient and can be operated with one hand. To disassemble the connection base 2 from the base 1, it is only necessary to push the driving block 102 to the front stop position, which is simple and convenient to operate.

[0032] In summary, the present embodiment provides a quick-detachable assembly pan-tilt head to solve the problem that the connection seat and the base are fixed and released by rotating the screw in the existing pan-tilt head, and the assembly requires two-handed operation, which is very inconvenient. The base 1 is mainly configured into a base shell 101, a driving block 102, a locking block 103 and an inner stop block 104. Since the driving block 102 can move forward and backward along the base shell 101, the locking block 103 moves to the locking position and the unlocking position along the base shell 101 in the left and right direction, and the inner stop block 104 can move to extend or retract the assembly surface 105, and the inner stop block When 104 extends out of the assembly surface 105, it abuts against the driving block 102 that drives the locking block 103 to the unlocking position (limiting the movement of the driving block 102). When the inner stop block 104 retracts into the assembly surface 105, the driving block 102 is released so that the driving block 102 drives the locking block 103 to move to the locking position. Therefore, the connection base 2 is placed on the assembly surface 105 of the base 1 to achieve the connection between the connecting base 2 and the base 1. The connection is quick and convenient and can be operated with one hand. To disassemble the connecting base 2 and the base 1, you only need to push the driving block 102 to the front stop position. The operation is simple and convenient.

[0033] In the embodiment of the utility model, a guide hole 107 is provided on one of the locking block 103 and the driving block 102, and a guide column 108 that slidably cooperates with the guide hole 107 is provided on the other of the two. When the driving block 102 moves forward and backward, the guide column 108 moves along the guide hole 107 to make the locking block 103 move left and right. Specifically, the guide hole 107 is provided on the locking block 103, and the direction of one locking block 103 toward the other locking block 103 is defined as a first direction, and the guide hole 107 extends obliquely from back to front in the first direction. The above arrangement is provided by providing the guide hole 107 on the locking block 103 and the guide column 108 on the driving block 102, and the guide hole 107 extends obliquely from back to front in the first direction, so that when the driving block 102 moves forward and backward, the locking block 103 can be driven to move left and right, and the oblique push connection structure is simple and easy to implement.

[0034] In the embodiment of the utility model, a clearance hole 109 and a stop hole 110 are formed on the driving block 102. The clearance hole 109 and the stop hole 110 are arranged front and back and connected to each other. The clearance hole 109 is at the front and the stop hole 110 is at the back. The inner stop block 104 has a stop surface 111. The stop hole 110 allows the inner stop block 104 to pass through when the inner stop block 104 moves up and extends out of the assembly surface 105. When the inner stop block 104 extends out of the assembly surface 105, it abuts on the side of the stop hole 110 adjacent to the clearance hole 109. When the inner stop block 104 moves down and retracts into the assembly surface 105, the clearance hole 109 allows the inner stop block 104 to partially pass through, so that the inner stop block 104 moves along the clearance hole 109 and abuts against the driving block 102 on the stop surface 111 to limit the upward movement of the inner stop block 104.

[0035] Since the inner stop block 104 passes through the stop hole 110 when the inner stop block 104 moves up and extends out of the assembly surface 105, and the inner stop block 104 abuts on the side of the stop hole 110 adjacent to the yield hole 109 when it extends out of the assembly surface 105, the inner stop block 104 can extend out of the assembly surface 105 and abut against the drive block 102 front and back to limit the movement of the drive block 102; and since the yield hole 109 allows the inner stop block 104 to partially pass through when the inner stop block 104 moves down and retracts into the assembly surface 105, the inner stop block 104 moves along the yield hole 109 and abuts against the drive block 102 on the stop surface 111, so that the drive block 102 can be released when the inner stop block 104 retracts into the assembly surface 105, and the drive block 102 can move backward.

[0036] In the embodiment of the utility model, the base shell 101 is provided with a first elastic member 112 on the side of the inner stop block 104 facing away from the assembly surface 105. The first elastic member 112 is used to make the inner stop block 104 move toward the direction of the assembly surface 105 and extend out of the assembly surface 105. The inner stop block 104 is provided with a first receiving hole 113 for the first elastic member 112 to be placed. Specifically, the first elastic member 112 is a spring. The above arrangement is provided by disposing the first elastic member 112 on the side of the inner stop block 104 facing away from the assembly surface 105, so that the inner stop block 104 can move toward the direction of the assembly surface 105 and extend out of the assembly surface 105. The driving structure is simple and easy to implement. In addition, by disposing the first receiving hole 113 on the inner stop block 104 for the first elastic member 112 to be placed, the first elastic member 112 and the inner stop block 104 are stably assembled and driven smoothly.

[0037] In the embodiment of the utility model, a positioning hole 114 is provided on the side of the base shell 101 opposite to the assembly surface 105 for inserting the inner stop block 104. Since the positioning hole 114 is provided on the side of the base shell 101 opposite to the assembly surface 105 for inserting the inner stop block 104, the inner stop block 104 and the base shell 101 are assembled stably.

[0038] In the embodiment of the utility model, the driving block 102 is provided with an outer stop block 115 that can move left and right along the driving block 102, and the base shell 101 has an exposed opening 116 for the outer stop block 115 to move out of the base shell 101. When the driving block 102 drives the locking block 103 to move to the locking position, the outer stop block 115 moves out of the base shell 101 from the exposed opening 116 and moves away from the driving block 102, so that the outer stop block 115 and the driving block 102 are staggered left and right and abut against the outer wall of the base shell 101 front and back. The above-mentioned arrangement is achieved by providing an outer stop block 115 on the driving block 102, which moves out of the base shell 101 and moves away from the driving block 102 when the driving block 102 drives the locking block 103 to move to the locking position, thereby staggering the driving block 102 left and right and abutting against the outer wall of the base shell 101 front and back, thereby restricting the driving block 102 to the outer stop position, thereby avoiding accidental touching of the driving block 102 and causing the driving block 102 to move forward (towards the front stop position) to unlock the locking block 103.

[0039] In the embodiment of the utility model, the outer stop block 115 is slidably connected to the driving block 102, and the outer stop block 115 has an outer stop cavity 117. The driving block 102 is provided with a connecting rod 118 extending into the outer stop cavity 117. The outer stop cavity 117 is provided with a second elastic member 119 with one end resting on the connecting rod 118 and the other end resting on the cavity wall of the outer stop cavity 117. When the driving block 102 drives the locking block 103 to move to the locking position, the second elastic member 119 drives the outer stop block 115 to move in the direction away from the driving block 102, so that the outer stop block 115 and the driving block 102 are staggered left and right. The above-mentioned arrangement configures an outer stop cavity 117 on the outer stop block 115, configures a connecting rod 118 on the driving block 102 with one end extending into the outer stop cavity 117, and configures a second elastic member 119 in the outer stop cavity 117, so that the outer stop block 115 can move in a direction away from the driving block 102 when moving out of the base shell 101, and the outer stop block 115 and the driving block 102 are staggered left and right, thereby avoiding accidental touching of the driving block 102 and causing the driving block 102 to move forward (towards the front stop position) to unlock the locking block 103.

[0040] In the embodiment of the utility model, one of the outer stop block 115 and the driving block 102 is provided with a guide groove 120 extending left and right, and the other of the two is provided with a guide bar 121 slidably matched with the guide groove 120. Since one of the outer stop block 115 and the driving block 102 is provided with a guide groove 120 extending left and right, and the other of the two is provided with a guide bar 121 slidably matched with the guide groove 120, the outer stop block 115 can move left and right along the driving block 102.

[0042] In the embodiment of the utility model, the outer stop block 115 has a base 122 slidably connected to the driving block 102 and a cover 123 detachably fixedly connected to the base 122, and the cover 123 and the base 122 are enclosed to form an outer stop cavity 117. The above arrangement is configured by configuring the outer stop block 115 as the base 122 slidably connected to the driving block 102 and the cover 123 detachably fixedly connected to the base 122, thereby facilitating the assembly connection of the outer stop block 115 and the driving block 102.

[0043] In the embodiment of the utility model, the base shell 101 has a downward groove 124 extending forward and backward, the driving block 102 is slidably connected to the downward groove 124, and a third elastic member 125 is provided in the downward groove 124 to drive the driving block 102 to move so that the driving block 102 drives the locking block 103 to move to the locking position. Specifically, the third elastic member 125 is a spring. Since the base shell 101 has a downward groove 124 slidably connected to the driving block 102, and a third elastic member 125 is provided in the downward groove 124 to drive the driving block 102 to move backward (toward the rear stop position), the driving block 102 can drive the locking block 103 to move to the locking position, and the driving structure is simple and easy to implement.

[0044] In the embodiment of the utility model, the driving block 102 is provided with a third receiving hole 126 for inserting one end of the third elastic member 125. The above arrangement is provided on the driving block 102 for inserting the third receiving hole 126, so that the third elastic member 125 and the driving block 102 are assembled stably.

[0045] In the embodiment of the utility model, the lower sliding groove 124 has two front and rear opposite shoulders 127, one of the shoulders 127 abuts against the driving block 102 when the locking block 103 moves to the locking position, and the other shoulder 127 abuts against the driving block 102 when the locking block 103 moves to the unlocking position. The shoulder 127 abutting against the driving block 102 when the locking block 103 moves to the locking position is defined as a rear shoulder, and the shoulder 127 abutting against the driving block 102 when the locking block 103 moves to the unlocking position is defined as a front shoulder. Since the lower sliding groove 124 has a rear shoulder that abuts against the driving block 102 when the locking block 103 moves to the locking position, and a front shoulder that abuts against the driving block 102 when the locking block 103 moves to the unlocking position, the movement of the driving block 102 can be limited when the locking block 103 moves to the unlocking position or the locking position, thereby avoiding excessive movement of the driving block 102.
