Description

Technical Field

[0001] This application relates to the field of photographic equipment, and in particular to an oiling fixture for a support leg locking mechanism used in photographic support devices. Background Technology

[0002] A photographic support device is a mechanism used to stabilize photographic equipment (such as cameras or camcorders), such as tripods or pan-tilt systems, to support and fix the equipment to prevent shaking. The support leg locking mechanism is a key component of the photographic support device, mainly comprising a drive cylinder, multiple actuator cylinders, and a hydraulic circuit assembly connecting the drive cylinder and the actuator cylinders via hydraulic lines. The drive cylinder supplies hydraulic oil to the actuator cylinders through the hydraulic circuit assembly, thereby driving the actuator cylinders to lock or release the angle of the support leg, adjusting the angle or extension length of the support leg.

[0003] The existing support leg locking mechanism has many problems in the lubrication stage during assembly. Because the cylinder assembly needs to be pre-assembled, it is impossible to lubricate multiple actuator cylinders and drive cylinders at the same time. Operators need to lubricate them one by one, which can easily lead to uneven lubrication.

[0004] Therefore, there is an urgent need for an oiling fixture that can solve the problem of uneven oiling during the oiling stage of the existing support foot locking mechanism during the assembly process. Utility Model Content

[0005] The main purpose of this application is to propose an oil injection fixture, which aims to solve the problem of uneven oil injection during the oil injection stage of the existing support foot locking mechanism in the assembly process.

[0006] To achieve the above objectives, this application proposes an oil injection fixture for use in the locking mechanism of a support foot of a photographic support device. The locking mechanism includes a drive cylinder, multiple actuator cylinders, and an oil circuit assembly connecting the drive cylinder and the actuator cylinders via oil pipes. The oil injection fixture includes: Base plate; A first support platform is disposed in the middle of the main plane of the base plate. The support surface of the first support platform is parallel to the main plane of the base plate and is used to support the oil circuit assembly mechanism. Multiple second support platforms are disposed around the periphery of the first support platform, and each second support platform is used to support a drive cylinder or an execution cylinder. An oil injection platform is disposed on the periphery of the first support platform to support one of the actuating cylinders; The bearing surfaces of the second bearing platform and the oil injection platform are set at a preset angle relative to the main plane of the base plate.

[0007] In some embodiments, the bearing surface of the oil injection platform is inclined at an angle to the main plane of the base plate; the plurality of second bearing platforms include: The first injection support platform includes a first support surface for supporting the hydraulic cylinder, the first support surface being inclined at an angle to the main plane of the base plate.

[0008] In some embodiments, the first bearing surface is disposed away from the main plane of the base plate, and the first bearing surface is recessed with a first receiving groove for bearing the actuating cylinder.

[0009] In some embodiments, the plurality of second carrier platforms further include: The second injection support platform includes a second support surface for supporting the drive cylinder, the second support surface being disposed away from the main plane of the base plate.

[0010] In some embodiments, the height of the second bearing surface relative to the main plane of the base plate is greater than the height of the first bearing surface relative to the main plane of the base plate.

[0011] In some embodiments, the oil injection platform includes a second receiving groove for supporting the actuating cylinder, and the side of the oil injection platform facing away from the main plane of the base plate is partially thinned to form the second receiving groove.

[0012] In some embodiments, the base plate has a flange protruding along the periphery of its main plane, and an oil groove is formed between the flange and the main plane for collecting hydraulic oil.

[0013] In some embodiments, the flange is provided with a collection hole, and the main plane is recessed with a collection groove, the collection groove being connected to the collection hole.

[0014] In some embodiments, the outer wall of the flange is provided with a pipe connection portion, the collection hole is formed in the pipe connection portion, and the pipe connection portion is used to connect to an external collection device through an oil pipe.

[0015] In some embodiments, a support beam is provided between the first support platform, the second support platform, and the oil injection platform, the support beam being used to support a portion of the oil circuit assembly mechanism.

[0016] This application provides an oil injection fixture, which includes a base plate, a first support platform, multiple second support platforms, and an oil injection platform. The first support platform is located in the center of the main plane of the base plate, and its support surface is parallel to the main plane of the base plate, so that the hydraulic circuit assembly can be horizontally fixed. The oil injection platform and multiple second support platforms are arranged around the first support platform at intervals. Each second support platform carries a drive cylinder or an actuator cylinder. The oil injection platform is used to carry an actuator cylinder. By injecting oil into the actuator cylinder, the oil is delivered to the hydraulic circuit assembly, the other actuator cylinders, and the drive cylinder. The support surfaces of the multiple second support platforms and the oil injection platform are set at a preset angle relative to the main plane of the base plate, so that the oil outlet of each cylinder is above the oil inlet, which facilitates the natural upward floating and discharge of air bubbles, reduces dead zones and residual air in the oil injection, and ensures uniform oil distribution, improves assembly efficiency, and enhances the sealing reliability of the hydraulic system.

[0022] This utility model embodiment proposes an oil injection fixture applied to the support foot locking mechanism of a photographic support device. The support locking mechanism includes a drive cylinder 100, multiple actuator cylinders 200, and an oil circuit assembly 300 connecting the drive cylinder 100 and the actuator cylinders 200 via oil pipes. (Refer to...) Figure 1 and Figure 2 In some embodiments, the oil injection fixture includes: Base plate 1; The first support platform 2 is located in the middle of the main plane 10 of the base plate 1. The support surface of the first support platform 2 is parallel to the main plane 10 of the base plate 1 and is used to support the oil circuit assembly mechanism 300. Multiple second support platforms 3 are arranged around the first support platform 2, and each second support platform 3 is used to support a drive cylinder 100 or an actuation cylinder 200. Oil injection platform 4 is set on the periphery of the first support platform 2 to support an actuating oil cylinder 200; The bearing surfaces of the second bearing platform 3 and the oil injection platform 4 are set at a preset angle relative to the main plane 10 of the base plate 1.

[0023] In this embodiment, by setting a base plate 1, a first support platform 2, multiple second support platforms 3, and an oil injection platform 4, the oil circuit assembly 300, the drive cylinder 100, and multiple actuation cylinders 200 can be simultaneously fixed on support surfaces in different postures, thereby realizing batch oil injection operations. Specifically: The bearing surface of the first bearing platform 2 is parallel to the main plane 10 of the base plate 1, so that the oil circuit assembly mechanism 300 can be installed horizontally on the first bearing platform 2. Multiple second bearing platforms 3 and oil injection platforms 4 are arranged around the first bearing platform 2 at intervals. Their bearing surfaces are set at a preset angle relative to the main plane 10 of the base plate 1. The preset angle between the second bearing platform 3 and the oil injection platform 4 can be parallel to the horizontal plane 10 of the base plate 1, or it can be set at a preset tilt angle relative to the main plane 10 of the base plate 1.

[0024] In this embodiment, since the bearing surfaces of the second bearing platform 3 and the oil injection platform 4 are set at a preset angle relative to the main plane 10 of the base plate 1, the drive cylinder 100 and multiple execution cylinders 200 are also set at an inclination. The oil outlets of the drive cylinder 100 and the execution cylinders 200 are both above the oil inlet. When oil is injected into the execution cylinders 200 on the oil injection platform 4, the oil can gradually fill the entire cylinder cavity after entering from the oil inlet until it overflows from the oil outlet, thus avoiding air bubbles and improving the oil injection efficiency.

[0025] In another embodiment, the preset angle of the oil injection platform 4 can be parallel to the main plane 10 of the base plate 1, and the multiple second support platforms 3 are set at a preset tilt angle to the main plane 10 of the base plate 1. In this embodiment, by setting the support surface of the oil injection platform 4 parallel to the main plane 10 of the base plate 1, the execution cylinder 200 in the initial position supported by the oil injection platform 4 is placed horizontally; since the support surfaces of the multiple second support platforms 3 are set at a preset tilt angle relative to the main plane 10 of the base plate 1, the oil injection ports of the drive cylinder 100 and other execution cylinders 200 installed on it are tilted upwards. The horizontal setting of the oil injection platform 4 makes the oil inlet of the initial execution cylinder 200 face the operator horizontally, which facilitates stable docking of the oil injection equipment and application of pressure for oil injection. Since the multiple second support platforms 3 are tilted, the oil outlets of the other cylinders are located on the upper side, which also allows the oil to flow from bottom to top in each cylinder, which facilitates the natural upward floating and discharge of air bubbles, reduces dead zones and residual air in oil injection, and ensures the sealing and response consistency of the oil circuit assembly mechanism 300.

[0026] Please continue to refer to Figure 1 and Figure 2 In some embodiments, the bearing surface of the oil injection platform 4 proposed in this application is set at an inclined angle to the main plane 10 of the base plate 1; the plurality of second bearing platforms 3 include: The first injection support platform 31 includes a first support surface 310 for supporting the hydraulic cylinder 200. The first support surface 310 is set at an inclined angle to the main plane 10 of the base plate 1.

[0027] In this embodiment, the application sets the bearing surface of the oil injection platform 4 at an inclined angle to the main plane 10 of the base plate 1, and the first bearing surface 310 of the first receiving bearing platform 31 among the multiple second bearing platforms 3 at an inclined angle to the main plane 10 of the base plate 1. This ensures that the execution cylinder 200, which serves as the starting position for oil injection, carried by the oil injection platform 4, and the execution cylinder 200, which serves as the receiving end, carried by the first receiving bearing platform 31, are both in an inclined posture. The inclined bearing surfaces of the oil injection platform 4 and the first receiving bearing platform 31 ensure that the oil inlet of the starting execution cylinder 200 and the other execution cylinders 200 are located on the lower side and the oil outlet is located on the upper side. This allows the oil to flow upward from the oil inlet to fill the cylinder body during injection, and air bubbles rise to the oil outlet and are discharged, preventing air bubbles from accumulating on the top or side wall of the cylinder body.

[0028] Please continue to refer to Figure 1 and Figure 2 In some embodiments, the first bearing surface 310 proposed in this application is disposed away from the main plane 10 of the base plate 1, and the first bearing surface 310 is recessed with a first receiving groove 3101 for bearing the hydraulic cylinder 200.

[0029] In this embodiment, the groove structure of the first receiving groove 3101 matches the outer contour of the actuator 200, and is used to accommodate and limit the radial displacement of the actuator 200; the first bearing surface 310 is set away from the main plane 10 of the base plate 1, so that the first receiving groove 3101 is open upward, which makes it easy for the actuator 200 to be put in from above and stably supported in an inclined posture, and avoids the actuator 200 from sliding or rotating relative to the first bearing surface 310 during the oil filling process.

[0030] Please continue to refer to Figure 1 and Figure 2 In some embodiments, the plurality of second support platforms 3 proposed in the embodiments of this application further include: The second injection support platform 32 includes a second support surface 320 for supporting the drive cylinder 100, and the second support surface 320 is disposed away from the main plane 10 of the base plate 1.

[0031] In this embodiment, by setting the second bearing surface 320 of the second injection bearing platform 32 to face away from the main plane 10 of the base plate 1, the drive cylinder 100 can be fixed upward to one of the multiple second bearing platforms 3. The second bearing surface 320 facing away from the main plane 10 of the base plate 1 allows the drive cylinder 100 to be placed from above and stably supported on the second injection bearing platform 32, preventing the drive cylinder 100 from sliding relative to the second bearing surface 320 during the oil injection process. Simultaneously, it facilitates the upward exposure of the oil injection port of the drive cylinder 100, aligning it with the oil pipe interface or oil pipe of the oil circuit assembly mechanism 300, ensuring that the oil flows smoothly into the drive cylinder 100 through the oil circuit assembly mechanism 300, achieving synchronous oil injection with the execution cylinder 200, and improving the consistency of hydraulic linkage.

[0032] Furthermore, in the embodiments of this application, the height of the second bearing surface 320 relative to the main plane 10 of the base plate 1 is greater than the height of the first bearing surface 310 relative to the main plane 10 of the base plate 1.

[0033] This application sets the height of the second bearing surface 320 relative to the main plane 10 of the base plate 1 to be greater than the height of the first bearing surface 310 relative to the main plane 10 of the base plate 1, so that the installation position of the drive cylinder 100 is higher than that of the actuator cylinder 200. The second bearing surface 320 being higher than the first bearing surface 310 makes the oil outlet of the drive cylinder 100 higher than the oil inlet of the actuator cylinder 200. This allows the oil to form a gravity-assisted downward trend within the oil circuit assembly 300, facilitating the rapid diffusion of oil from the drive cylinder 100 to the multiple actuator cylinders 200. At the same time, the height difference ensures that the oil inlets of each actuator cylinder 200 are located at a lower position, making it easier for air bubbles to rise to the oil outlet of each actuator cylinder 200 for discharge, reducing the venting steps, thereby shortening the overall oiling cycle and improving filling uniformity.

[0034] Please continue to refer to Figure 1 and Figure 2 In some embodiments, the oil injection platform 4 proposed in this application includes a second receiving groove 40 for supporting the hydraulic cylinder 200. The side of the oil injection platform 4 facing away from the main plane 10 of the base plate 1 is partially thinned to form the second receiving groove 40.

[0035] In this embodiment, the second receiving groove 40 is formed by partially thinning the side of the oil injection platform 4 facing away from the main plane 10 of the base plate 1, so that the starting end execution cylinder 200 can be fitted and fixed to the oil injection platform 4. The groove structure of the second receiving groove 40 matches the outer contour of the execution cylinder 200, and is used to accommodate and limit the radial displacement of the execution cylinder 200; the partial thinning makes the second receiving groove 40 open upward, which facilitates the execution cylinder 200 to be placed from above and stably supported at a preset angle posture, avoiding the execution cylinder 200 from sliding or rotating relative to the oil injection platform 4 during the oil injection process, and realizing the uniform injection of oil from the starting end into the oil circuit assembly mechanism 300.

[0036] Please continue to refer to Figure 1 and Figure 2 In some embodiments, the base plate 1 proposed in this application is provided with a flange 101 protruding along the periphery of its main plane 10, and an oil groove 102 is formed between the flange 101 and the main plane 10, the oil groove being used to collect hydraulic oil.

[0037] In this embodiment, the present application provides a flange 101 protruding from the periphery of the main plane 10 of the base plate 1, forming an oil groove 102 between the flange 101 and the main plane 10, so that the hydraulic oil overflowing during the oil injection process can be collected. The flange 101 protrudes upward to form a bottomed enclosure structure with the main plane 10 of the base plate 1, and the flange 101 is used to prevent hydraulic oil from flowing out from the edge of the base plate 1; the recessed space of the oil groove 102 is used to accommodate the overflowing oil, avoiding the waste of hydraulic oil and facilitating subsequent centralized cleaning or recycling.

[0038] Furthermore, in some embodiments, the flange 101 proposed in this application embodiment is provided with a collection hole 103, and the main plane 10 is recessed with a collection groove 104, which is connected to the collection hole 103.

[0039] This application provides a collection hole 103 through the flange 101 and a collection groove 104 recessed in the main plane 10, with the collection groove 104 connected to the collection hole 103, so that the overflow oil collected in the oil tank 102 can be discharged in an orderly manner.

[0040] The recessed structure of the collection groove 104 is used to guide the hydraulic oil in the oil groove 102 to the collection hole 103 to avoid the oil from accumulating or overflowing in the oil groove 102; the collection hole 103 passes through the flange 101 and is used to discharge the collected oil to the outside of the fixture (exemplarily, such as connecting a hose to a recovery container), so as to facilitate cleaning or centralized recovery of hydraulic oil.

[0041] Please continue to refer to Figure 1 and Figure 2 In some embodiments, a bearing beam 5 is provided between the first bearing platform 2 and the second bearing platform 3, and between the first bearing platform 2 and the oil injection platform 4, as proposed in the embodiments of this application. The bearing beam 5 is used to support part of the oil circuit assembly mechanism 300.

[0042] In this embodiment, the supporting beam 5 connects each supporting platform to form an overall frame, which is used to bear the weight of the oil pipe of the oil circuit assembly 300 and the oil injection pressure, and to prevent the oil pipe from drooping or twisting excessively on the horizontal first supporting platform 2. At the same time, the supporting beam 5 bridges the peripheral second supporting platform 3 and the oil injection platform 4 to the center, ensuring that the oil pipe interface of the oil circuit assembly 300 is stably aligned with the oil injection port of each oil cylinder, realizing smooth oil flow and preventing pipeline fatigue fracture, improving the reliability of the oil injection process and the assembly accuracy of the hydraulic system, while facilitating the removal and placement of the oil circuit assembly 300.

[0043] The above description is only a part or preferred embodiment of this application. Neither the text nor the drawings should limit the scope of protection of this application. All equivalent structural transformations made using the content of this application's specification and drawings under the overall concept of this application, or direct / indirect applications in other related technical fields, are included within the scope of protection of this application.
