Description

Technical Field

[0001] The invention relates to an electronic equipment structure, in particular to a portable anti-overturning tripod. Background Art

[0002] Most of the known military portable tripod mounting surfaces and level indicating devices are liquid bubble levels. When the temperature fluctuates greatly or is minus 40°, the position of the sighting axis and the level tube axis will shift due to the different materials of the base and the level, and the different thermal expansion and contraction coefficients, and the accuracy of the liquid bubble level will be significantly reduced.

[0003] For military equipment, it is often necessary to check the horizontal state of the equipment after setting it up. Most of the known tripods have inconvenient level gauges, which is not conducive to timely finding the horizontal state of the equipment and adjusting it in time. Under certain weight and size restrictions, the load capacity is low. At the same time, the working environment of military equipment is harsh. It is difficult to meet the requirements in environments with strong winds and sand or when the load capacity of military equipment is large. Summary of the invention

[0004] The purpose of the invention is to provide a portable anti-overturning tripod, which can be quickly erected and leveled and adapt to the harsh working environment with strong wind and sand and frequent temperature changes.

By rotating the locking piece, the tapered threads of the locking piece and the connecting piece are gradually tightened, the connecting piece and the inner rod are pressed tightly, and the inner rod cannot move due to the friction between the connecting piece and the inner rod, thereby achieving fixation at any position; The inner rod is embedded in the supporting foot, and the third stopper is pushed by the compression of the third spring, so that the body of the third stopper is embedded in the supporting foot, and the boss of the third stopper is embedded in the opening of the inner rod, so that the inner rod and the supporting foot are relatively fixed; The screw passes through the threaded hole of the connector, the outer rod and the through hole of the gasket, the end face of the screw contacts the outer surface of the inner rod, and the screw cap of the screw is embedded in the groove of the outer ring to fix the outer ring, the connector, the gasket and the outer rod.

[0008] Furthermore, the leveling device comprises a pointer and a suspension shaft, the pointer points to a direction marking scale line, an extension line of the scale line passes through the center of the suspension shaft and is perpendicular to the pointer installation surface.

[0009] Furthermore, there are three leveling devices, one of which is provided on the mounting surface of each leg. After the tripod is erected, the entire device can be horizontally adjusted by adjusting any two of the supporting legs so that the directions of the two pointers are consistent with their corresponding marking lines.

[0010] Furthermore, the support leg includes a support leg, a screw, a sphere, an end cap, a connector, and a rotating shaft support, wherein: The support foot is connected to the sphere through screws, the end cover clamps the sphere inside the connecting piece, the rotating shaft is supported in the transition between the sphere and the connecting piece, the end cover is connected to the connecting piece through screws, and the connecting piece is connected to the supporting leg.

[0011] Furthermore, the support leg includes a boss and a ground nail installation hole to increase friction.

[0012] Furthermore, the connecting device includes a connecting rod, a connector and a ground nail mounting hole, wherein there are three connecting rods, each connected to a supporting leg, and the three connecting rods are connected by a connector to form a tripod structure, thereby increasing the stability of the base. At the same time, a ground nail mounting hole is arranged in the center of the connector, and the wind resistance of the tripod is increased by installing the ground nail.

[0013] Compared with the prior art, the present invention has the following significant advantages: 1) The equipment installation and leveling process is simple and time-saving. The leveling device is a pure structural device and is less affected by the external environment. At the same time, anti-overturning equipment is installed to adapt to special environments with strong winds and sand and large temperature changes. 2) The tripod adopts a partial carbon fiber structure, which has a small size and light weight after shrinking, and can bear heavy military equipment at the same time, and is easy to carry.

[0016] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0017] The present invention discloses a portable anti-overturning tripod, which comprises a base 1, three supporting legs 2, a leveling device 3, supporting feet 4 and a connecting device 5.

[0018] The base mounting surface 1-1 is a regular hexagon and bilaterally symmetrical. The three supporting legs 2 are evenly distributed. The vertical surface 1-2 adjacent to the side of the base mounting surface is installed with a leveling device 3. In addition, the adjacent side surface of the leveling device mounting surface is installed with a handle 1-3, which is used to install a wind-resistant pull rope to achieve the purpose of anti-overturning.

[0019] The leveling device 3 includes a pointer 3-1 and a suspension shaft 3-2. The pointer points to a marking line, and the extension line of the marking line passes through the center of the suspension shaft and is perpendicular to the pointer installation surface. After the equipment is erected, by adjusting any two of the support legs 2 so that the directions of the two pointers are consistent with their corresponding marking lines, the level adjustment of the entire equipment can be achieved.

[0020] The support leg 2 includes a rotating shaft support 2-1, an inner rod 2-2, an outer rod 2-3, a locking member 2-4, a connecting member 2-5, a first spring 2-6, a first stopper 2-7, a guide member 2-8, a second spring 2-9, a second stopper 2-10, a third spring 2-11, a third stopper 2-12, a screw 2-13, an outer ring 2-14 and a gasket 2-15. The support leg 2 is connected to the base 1 through the rotating shaft support 2-1, the rotating shaft is embedded in the groove of the base, and the rotating shaft support 2-1 is fixed in the groove of the base by screws and nuts to realize the rotation of the support leg, thereby completing the erection and storage of the tripod. The outer rod 2-3 of the support leg is embedded in the groove of the rotating shaft support 2-1, and the first stopper 2-7 is pushed by the compression of the first spring 2-6 to realize the relative fixation of the outer rod 2-3 and the rotating shaft support 2-1, so that they are connected as a whole. The guide member 2-8 is embedded in the inner rod 2-2 of the support leg. By utilizing the compression of the second spring 2-9, the second stopper 2-10 is pushed to achieve relative fixation of the inner rod 2-2 and the guide member 2-8, and they are connected as one. The connector, the outer ring and the liner are fixed by screws. During the erection of the tripod, the inner rod 2-2 is pulled out to achieve the erection of various heights. The liner 2-15 limits the maximum stroke of the inner rod, prevents the inner rod 2-2 from falling off, and achieves the maximum height of the tripod. The locking member 2-4 is connected to the connector by a threaded connection. The connector 2-5 is pressed against the inner rod 2-2 by the locking member 2-4, and the friction between the connector 2-5 and the inner rod 2-2 is increased to achieve the purpose of locking the inner rod 2-2, thereby achieving fixation at any position. The inner rod 2-2 is embedded in the support foot 4, and by utilizing the compression of the third spring 2-11, the third stopper 2-12 is pushed to achieve relative fixation of the inner rod 2-2 and the support foot 4, and they are connected as one. The supporting feet 4 are in contact with the ground.

[0021] The support leg includes a support leg 4-1, a screw 4-2, a sphere 4-3, an end cap 4-4, a connector 4-5, and a shaft support 4-6. The support leg 4-1 is connected to the sphere 4-3 by means of a screw 4-2, and the sphere 4-3 is clamped inside the connector 4-5 by means of the end cap 4-4, while the shaft support 4-6 is in the middle of the transition, and the sphere 4-3 can rotate inside the end cap 4-4 and the shaft support 4-6 to achieve the goal of universal rotation. The support leg 4-1 includes a boss 4-7 and a ground nail installation hole 4-8 to increase friction and achieve the purpose of anti-overturning.

[0022] In the connecting device 5, the connecting rod 5-1 is connected to the outer ring 2-14 and the connector 5-2 respectively by rivets. After the tripod is erected, the connecting rod 5-1 is in a horizontal state. At the same time, the rotating shaft support 2-1 connected to the supporting leg 2 contacts the edge of the base 1 to generate an interaction force, thereby increasing the stability of the base 1. At the same time, a ground nail installation hole is set in the center of the connector 5-2. Installing the ground nail can increase the wind resistance of the tripod.
