Description

Technical Field

[0001] The present application relates to the field of photographic equipment, and in particular to a quick-release plug, an interface assembly, and photographic equipment. Background Art

[0002] The QD (Quick Detach) connector is a camera accessory connector commonly used to connect cameras to other accessories, such as shoulder straps, suspenders, and grips. It offers a convenient and quick interface. A QD connector typically consists of two parts: a socket and a plug. The socket is typically mounted on the camera, while the plug is mounted on the camera accessory. The socket and plug are connected using a bayonet or threaded connection to ensure a secure and reliable connection.

[0003] In some quick-release connectors that connect with snaps, the disassembly process typically requires first pressing the actuator on the top of the plug, toward the connector socket, to unlock the connector socket and the plug. Then, maintaining the pressure, pull the plug away from the connector socket to separate them. This disassembly process involves applying force in opposite directions, which is inconsistent with user habits and inconvenient. Utility Model Content

When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element.

[0037] In addition, the descriptions of "first", "second", etc. in this application are for descriptive purposes only and should not be understood as indicating or implying their relative importance or implicitly indicating the number of the technical features indicated. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between the various embodiments can be combined with each other, but this must be based on the fact that they can be implemented by ordinary technicians in this field. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0038] This application proposes a quick-release plug, referring to Figures 1 to 3 The quick-release plug includes: a connector seat, an accommodating cavity A is axially provided inside, and a side wall at one end of the connector seat is further provided with a first mounting hole 21 connected to the accommodating cavity; a locking member 30 is floatingly arranged in the first mounting hole 21; a transmission member 40 is arranged in the accommodating cavity A, and the side portion of the transmission member 40 can abut against the locking member 30, so that the locking member 30 partially extends out of the first mounting hole 21; an elastic member 60 is arranged in the accommodating cavity A, and is used to make the transmission member 40 abut against the locking member 30; a driving member 50 is provided on the connector seat, and one end is located in the accommodating cavity A and is connected to the transmission member 40; the driving member 50 is used to drive the transmission member 40 to move axially, so that a first avoidance space is formed between the transmission member 40 and the first mounting hole 21 for the locking member 30 to retract.

[0039] In this embodiment, the connector seat can be an integrated structure or a structure connected by multiple parts. The locking member 30 can be a pin that is compatible with the first mounting hole 21, or a steel ball. Specifically, 2 to 4 steel balls can be set along the circumference. The inner diameter of the first mounting hole 21 is smaller than the outer diameter of the steel ball, and the steel ball can also partially extend out of the first mounting hole 21. The transmission member 40 can be provided with two continuous sections, the outer diameter of one section is larger than the outer diameter of the other section, and one of the sections with a larger outer diameter abuts against the locking member 30, so that the locking member 30 is partially exposed from the outer end of the first mounting hole 21. When the transmission member 40 is driven by the driving member 50 to move along the axis, the section with a smaller outer diameter of the transmission member 40 corresponds to the locking member 30, and the space between the section with a smaller inner diameter and the inner end of the second mounting hole 21 constitutes the above-mentioned first avoidance space. The locking member 30 can then retract into the first avoidance space to achieve unlocking with the external interface seat.

[0040] The elastic member 60 may be a spring, the elastic force of which causes the transmission member 40 to abut against the locking member 30, the locking member extending from the first mounting hole 21, and locking the interface seat. One driving member 50 may be provided, or two driving members 50 may be symmetrically provided. Pressing the driving member 50 on the side wall of the base 10 can push the transmission member 40 to move in a direction away from the free end of the plug-in member 20, and move the transmission member 40 away from the locking member 30. The portion of the locking member 30 extending outside the connector seat will return to the first mounting hole 21 and complete the unlocking, and the quick-release plug can be subsequently unplugged. The force application direction of the driving member 50 intersects with the plug-in and unplugging direction, which is more ergonomic and more convenient to operate. It is worth noting that, based on the usage scenario, the driving member 50 mentioned in the embodiment of the present application can complete the above-mentioned unlocking operation by an external driving force applied to the driving member 50, such as the driving member 50 can move along the axis by pushing or pulling the transmission member 40. Alternatively, it can be a traditional power source such as a motor or cylinder, capable of providing its own driving force, so that upon touching or pressing the unlock button, the transmission member 40 is activated to generate kinetic energy, thereby driving the transmission member 40 to move along its axis. It is understood that the driving member 50 can also be connected to the actuator. When the actuator is rotated or slid, the driving member 50 can be driven to push or pull the transmission member 40. For example, a slide groove and a limit post are provided between the actuator and the driving member 50, enabling the actuator to drive the driving member 50 to slide. The limit post is located within the slide groove, which can be an arc-shaped groove.

[0041] In this embodiment, referring to Figure 2The connector seat can be configured as a spliced ​​structure, specifically including a base 10 and a plug-in connector 20. A first receiving hole 11 is provided at one end of the base 10. The plug-in connector 20 includes a connecting end 24 that docks with the first receiving hole 11. The connecting end 24 is provided with a second receiving hole 22 for receiving the transmission member 40. The first receiving hole 11 and the second receiving hole 22 constitute a receiving cavity A. The second receiving hole 22 is provided at one end of the plug-in connector 20, thereby facilitating the installation of accessories in the receiving cavity A, such as the transmission member 40, the driving member 50, the elastic member 60, etc. The plug-in connector 20 can be threadedly connected to the base 10. Specifically, an internal thread can be provided on the inner wall of the first receiving hole 11, and an external thread can be provided on the outer wall of the connecting end 24 of the plug-in connector 20. In this way, the plug-in connector 20 can be screwed into the first receiving hole 11, facilitating the installation of the transmission member 40, the driving member 50, and the elastic member 60 in the receiving cavity A.

[0042] Further references Figure 4 and Figure 5 The side wall of the connector seat is provided with a second mounting hole 12 connected to the accommodating chamber A, and the driving member 50 is slidably connected to the second mounting hole 12. A limiting structure is provided between the driving member 50 and the connector seat for limiting the driving member 50 from detaching from the connector seat. One end of the driving member 50 is located in the accommodating chamber A and abuts against the transmission member, and the other end extends out of the connector seat.

[0043] In this embodiment, referring to Figure 2 The limiting structure can also be realized based on the connection relationship between the driving member 50 and the plug-in member 20. The specific solution is: the second mounting hole 12 is provided on the side wall of the base 10, and the driving member 50 is provided with a limiting groove 51 on the side facing the connecting end 24. The upper end of the connecting end 24 extends to the inner side of the second mounting hole 12 to form a limiting protrusion. The connecting end 24 is provided in the limiting groove 51. The limiting groove 51 and the connecting end 24 constitute a limiting structure with a compact structure, space saving, and easy production. The limiting groove 51 can match the shape of the upper end of the connecting end 24, such as an arc groove.

[0044] In this embodiment, in order to realize the assembly of the driving member 50 from the outside to the inside, the peripheral side of the driving member 50 cannot be provided with a convex limiting structure, and its limiting method needs to be realized in conjunction with the connecting end 24. Specifically, the above-mentioned limiting groove 51 can be provided, and the length direction of the limiting groove 51 can be perpendicular to the length direction of the driving member 50, and the limiting groove 51 can be provided as a through groove. In the specific assembly process, the driving member 50 can be first installed into the second mounting hole 12 from the outside to the inside with the limiting groove 51 facing the plug-in connector 20. After installing other components, the plug-in connector 20 can be installed so that the connecting end 24 is inserted into the limiting groove 51. At this time, the connecting end 24 can form a certain obstruction at the second mounting hole 12, and the inner wall of the second accommodating hole 22 can abut against the inner wall of the second accommodating hole 22, thereby preventing the driving member 50 from falling out. Correspondingly, the first mounting hole 21 is provided on the side wall of the plug-in connector 20.

[0045] In some embodiments, the base 10 and the connector 20 can also be connected by a screw. Specifically, the base 10 and the connector 20 are included, and the accommodating chamber A is formed by two chambers constructed in the base 10 and the connector 20 and spliced ​​together along the axial direction. The base 10 and the connector 20 can be fixedly connected by a screw. For example, one end of the screw passes through the connector 20 and is screwed to the base 10. The second mounting hole 12 forms a side wall of the base 10. The screw passes through the side wall of the second mounting hole 12 and extends into the second mounting hole 12 to enter the limiting groove 51 of the driving member 50. The protruding end of the screw can serve as the aforementioned limiting protrusion. The protruding end of the screw can slide in the limiting groove 51. When it contacts the groove wall of the limiting groove 51, it limits the driving member 50 to prevent it from disengaging from the second mounting hole 12.

[0046] Of course, the connector 20 and the base 10 can also be fixedly connected by bonding, welding or interference fit.

[0047] The connector base is constructed of two sections, or two halves. The connector base may include a left base body and a right base body, which are joined to form a receiving chamber A for accommodating the elastic member 60, the transmission member 40, and the driver 50. The left and right base bodies may be fastened together by screws or other fasteners, or may be fixedly connected by other structures.

[0048] In some embodiments, the limiting structure functions to prevent the driver 50 from disengaging from the second mounting hole 12. The limiting structure can be implemented in a variety of ways, such as by a protrusion provided on the periphery of the driver 50, which can be located at the end of the driver 50. The driver 50 can abut against the edge of the inner end of the second mounting hole 12, preventing it from disengaging from the base 10 from the inside out. It is worth noting that since the limiting structure in this embodiment is provided protruding from the periphery of the driver 50, when assembling the driver 50, it must first be inserted into the first receiving hole 11 and then extended from the inside out through the second mounting hole 12. Alternatively, a notch can be provided in the second mounting hole 12 for the protrusion to pass through, and then the driver 50 can be rotated to offset the protrusion from the notch, thereby achieving the desired positioning. For another example, the sidewall of the second mounting hole 12 can be provided with a limiting protrusion, and the sidewall of the driver 50 can be provided with a limiting groove 51 for accommodating the limiting protrusion. The limiting groove 51 and the limiting protrusion form the limiting structure.

[0049] In some embodiments, reference Figure 2 and Figure 6 The driving member 50 drives the transmission member 40 to move axially, which can be achieved through the guiding bevel. The driving member 50 can be arranged on the peripheral side of the joint seat and can slide radially. The transmission member 40 includes a first abutting section for docking with the driving member 50, and the surface of the first abutting section that abuts the driving member is provided with a guiding bevel.

[0050] In this embodiment, referring to Figure 5 The transmission member 40 includes a first abutting section 42, a first avoiding section 43, a second abutting section 45, and a second avoiding section 46, which are connected in sequence. The first abutting section 42 is used to connect with the driving member 50, and the second abutting section 45 is used to connect with the locking member 30. The upper side surface of the end of the driving member 50 located in the first accommodating hole 11 is abutting surface 53. This abutting surface 53 can be set as an inclined surface. The side corresponding to the first abutting section 42 can also be set as an inclined surface. The two inclined surfaces fit together and can also guide the transmission member 40. When the driving member 50 is pushed inward, due to the guiding effect of the guiding inclined surface, the driving member 50 can push the transmission member 40 to move upward along the axial direction.

[0051] In this embodiment, the transmission member 40 also includes a second abutting section 45 for abutting the locking member 30, and a first avoidance section 43 provided between the first abutting section 42 and the second abutting section 45; a second avoidance space for the inward movement of the driving member 50 is formed between the side wall of the accommodating chamber A and the first avoidance section 43. A first avoidance space for the movement of the driving member 50 is formed between the first accommodating hole 11 and the first avoidance section 43. The provision of the first avoidance space and the provision of the second avoidance space can respectively provide a certain amount of movement space for the driving member 50 and the locking member 30 when they move inward. The first abutting section 42 is used to abut the driving member 50, and the second abutting section 45 is used to abut the locking member 30. The outer diameter of the second avoidance section 46 is smaller than the outer diameter of the second abutting section 45, and the outer peripheral surface of the second avoidance section 46 and the inner wall of the accommodating chamber A form the above-mentioned first avoidance space. Of course, the second escape section 46 at the end of the transmission member 40 can also be provided with a chamfer. The chamfered surface and the inner wall of the second accommodating hole 22 form a first escape space for the locking member 30 to retract. At the same time, when the locking member 30 retracts, it can also maintain contact with the second escape section 46, preventing the locking member 30 from completely separating from the first mounting hole 21, thereby playing a role of limiting the position.

[0052] Of course, the transmission member 40 includes a guide section that is slidably connected to the accommodating cavity A. The transmission member 40 may specifically include a first guide section 41, a first abutting section 42, a first avoidance section 43, a second guide section 44, a second abutting section 45, and a second avoidance section 46 that are sequentially connected. The first guide section 41 and the first abutting section 42 are disposed in the first accommodating hole 11, and the second guide section 44 and the second abutting section 45 are disposed in the second accommodating hole 22. The first guide section 41 is adapted to the first accommodating hole 11 and can guide the movement of the transmission member 40. The second guide section 44 is adapted to the second accommodating hole 22 and also serves a guiding role. That is, the first guide section 41 and the inner hole wall of the first accommodating hole 11, and the second guide section 44 and the second accommodating hole 22, both have a clearance fit.

[0053] In addition, the end surface of the transmission member 40 away from the plug-in member 20 can be provided with a third mounting hole 47, one end of the elastic member 60 is arranged in the third mounting hole 47, and the other end is in abutment with the base 10. The third mounting hole 47 can utilize the internal space of the transmission member 40 in the axial direction, further shortening the overall length of the quick release plug in structure.

[0054] In some embodiments, a plurality of locking members 30 are arranged on the joint seat along the circumference, and a plurality of driving members 50 are arranged on the joint seat along the circumference. The driving member can be two buttons arranged on the outer circumference of the joint seat, which can be arranged in axial symmetry, and the unlocking can be completed by pressing the buttons inward. Of course, the locking member 30 can be 2-4 steel balls arranged around the joint seat, which can also be arranged in axial symmetry to ensure the circumferential and stable locking of the interface seat 70.

[0055] In some embodiments, the section of the plug-in member 20 used for interfacing with the interface seat 70 is the plug-in section 23, and the length of the plug-in section 23 is less than 6mm. In this embodiment, arranging the driving member 50 on the side of the quick release plug can shorten the overall length. Since the maximum thickness of the rabbit cage is only 6mm, the length of the male plug of the existing QD interface is too long, and the connection between it and the camera must be connected through a separate interface seat 70 with a rope and a camera hanging hole, which has certain limitations in use. By limiting the length of the plug-in section 23, the structure of the interface seat 70 can be directly integrated into the rabbit cage, and it can also be compatible with other plug-in depth interface seats 70. Of course, the structure of the interface seat 70 can also be directly integrated into other photographic accessories, such as an adapter bracket, a tripod, a magic hand, etc. In addition, the accommodation cavity A can extend into the plug-in section 23, and the first mounting hole 21 is arranged through the side wall of the plug-in section 23.

[0056] In the above embodiments, the driving member 50 is located on the side of the joint seat or the base 10, and of course the driving member can also be arranged on the end of the joint seat. Referring to Figure 7, specifically, the driving member 50 can be arranged at one end of the joint seat away from the locking member 30 and in sliding connection with the joint seat along the axial direction; one end of the driving member penetrates through the joint seat and is connected with the transmission member. Specifically, a threaded hole can be further arranged at the bottom of the third mounting hole 47, and one end of the driving member 50 penetrates through the end of the joint seat and is connected with the threaded hole. The elastic member 60 is sleeved on the outer periphery of the section of the driving member 50 located in the third mounting hole 47. The upper end of the elastic member and the transmission member 40 can abut against the top wall of the accommodating cavity A, thereby playing a role of end limiting. Pulling the part of the driving member 50 located outside the joint seat can drive the transmission member 40 to move along the axial direction, so that the locking member 30 is withdrawn into the first avoiding space, and the unlocking is completed. The force direction of the unlocking driving force is consistent with the pulling-out direction of the quick-release plug, which conforms to the operation logic. The application further provides an interface assembly, which comprises an interface seat 70 and the quick-release plug described above, the interface seat 70 is provided with a plug-in hole 71 for connecting with the plug-in member 20, the side wall of the plug-in hole 71 is provided with an abutting groove 72 for abutting with the locking member, and the abutting groove 72 can be an annular groove. The end of the base 10 of the quick-release plug described above can be further provided with a connecting ring 13, and the connecting ring 13 can be used for connecting a hanging rope.

[0057] The application further provides a photographic equipment comprising the quick-release plug described above. The photographic equipment described above comprises a camera and / or a rabbit cage, the interface seat 70 abutting with the quick-release plug can be connected with the camera and the rabbit cage through a rope sleeve, or the interface seat 70 can be directly integrated on the camera or the rabbit cage, so that the quick-release plug is quickly connected.

[0058] The application provides working principles of the quick-release plug, the interface assembly and the photographic equipment as follows:

[0059] In the following, two driving members 50 and steel balls as the locking members are taken as examples for illustration. In the initial state, the quick-release plug is in the locked state. When the two driving members 50 are synchronously pressed by hands during the unlocking process, the plurality of steel balls are simultaneously released and are not limited and can be retracted into the accommodating cavity A. At this time, the plug-in end of the plug-in member 20 can be smoothly inserted into the interface seat 70, and then the driving members 50 are released. Under the action of the elastic member 60, the transmission member 40 moves downward, and the space for the movement of the steel balls is occupied. At this time, the steel balls are clamped in the abutting groove 72 inside the interface seat 70, that is, the connection and mechanical locking function of the quick-release plug and the interface seat 70 are realized. When the two unlocking driving members 50 are synchronously pressed by hands at this time, the transmission member 40 moves upward, the steel balls are not limited, the quick-release plug is pulled out, and the quick-release plug can be separated from the interface seat 70.

[0060] Of course, the unlocking driving members 50 are triggered from the circumferential direction of the quick-release plug. The size specification of the interface seat 70 of the previous QD interface is completely compatible, and the length is extremely shortened, so that the interface seat 70 can be directly integrated on the rabbit cage, and the driving member 50 of the QD interface is not directly above, and the top hanging rope port and the ID modeling have more degrees of freedom.

[0061] The above merely provides part or preferred embodiments of the present application, and neither the text nor the drawings can limit the scope of protection of the present application. Any equivalent structure variations made with the contents of the present application and the drawings, or direct / indirect application in other related technical fields shall fall within the scope of protection of the present application.
