Description

Technical Field

[0001] The utility model relates to the technical field of life buoys, in particular to a life buoy conveying mechanism. Background Art

[0002] Lifebuoy refers to a kind of water lifesaving equipment, usually made of cork, foam, plastic or other light materials with low specific gravity, and covered with canvas, plastic, etc. Since the volume of lifebuoy increases after inflation and most of them are round, when transporting lifebuoys, if they are manually held, the number of lifebuoys held at a time is limited; if they are pushed by a trolley, too many lifebuoys will cause them to slip easily; if a positioning mechanism is used to position the lifebuoy, it is impossible to match lifebuoys of different diameters. Utility Model Content

[0003] In view of the deficiencies in the prior art, the utility model provides a lifebuoy conveying mechanism to solve the problems mentioned in the above background technology.

[0004] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0005] A life buoy conveying mechanism comprises a trolley, which is connected to a center rod. Two limit rods with telescopic functions are connected to the outer ring of the center rod on the trolley, and the distances between the two limit rods and the center rod are equal. A driving mechanism for controlling the two limit rods to move toward or in opposite directions at the same time is arranged in the trolley.

[0006] Preferably, a driving cavity is provided in the cart, and sliding holes communicating with the driving cavity are provided on both sides of the center rod on the top surface of the cart. The driving mechanism includes a screw rod rotatably connected to the driving cavity, a motor installed at one end of the cart and transmission connected to the screw rod, reverse threads are provided on both sides of the screw rod, and sliders are threadedly connected on both sides of the screw rod, the sliders are slidably connected to the sliding holes, and the limit rod is connected to the slider.

[0007] Preferably, the limiting rod includes an outer tube and an inner tube slidably connected to the outer tube, a first positioning hole is opened on the upper part of the outer tube, and a plurality of second positioning holes are opened on the inner tube. The inner tube is fixed to the outer tube by the cooperation of a pin, the second positioning hole and the first positioning hole.

[0008] Preferably, the cart is provided with a control box, in which a controller and a battery are provided, and the controller is provided with a start button, and the motor and the start button are electrically connected to the controller.

[0009] Compared with the prior art, the utility model has the following beneficial effects:

[0010] Multiple lifebuoys are overlapped on the cart, and the lifebuoys are limited by the center rod and the limit rod to prevent them from slipping, so that more lifebuoys can be transported at one time. If you want to increase the number, you can extend the length of the limit rod to further increase the number of lifebuoys transported.

[0011] After the life buoy is put on the center rod, the two limit rods are controlled by the driving mechanism to move toward each other at the same time, which will clamp the life buoy to prevent it from slipping, thereby adapting to life buoys of different diameters.

[0015] 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 in 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.

[0016] See also Figure 1-2 A life buoy conveying mechanism includes a trolley 1, which is connected to a center rod 2. Two limit rods 3 with telescopic function are connected to the outer ring of the center rod on the trolley 1. The distances between the two limit rods 3 and the center rod 2 are equal. The limit rod 3 includes an outer tube 31 and an inner tube 32 slidably connected to the outer tube. A first positioning hole 33 is opened on the upper part of the outer tube 31, and a plurality of second positioning holes 34 are opened on the inner tube 32. The inner tube 32 is fixed to the outer tube 31 by the cooperation of a pin 35, the second positioning hole 34 and the first positioning hole 33. By increasing the length of the limit rod, the placement amount of the life buoy can be increased.

[0017] The cart 1 is provided with a driving mechanism for controlling the two limit rods 3 to move toward or in opposite directions at the same time. The cart 1 is provided with a driving cavity, and the top surface of the cart 1 is provided with sliding holes 4 connected to the driving cavity on both sides of the center rod. The driving mechanism includes a screw rod 5 rotatably connected to the driving cavity, a motor 6 installed at one end of the cart and connected to the screw rod in a transmission manner, and the screw rod 5 is provided with opposite threads on both sides, and the screw rod 5 is threadedly connected with sliders 7 on both sides. The sliders 7 are slidably connected to the sliding holes 4, and the limit rod 3 is connected to the slider 7, and the distances from the two sliders to the center of the screw rod are the same. Starting the motor and driving the screw rod to rotate can drive the two sliders to move in the same direction at the same time, thereby driving the limit rod to move to clamp the life buoy.

[0018] The cart 1 is provided with a control box 8, in which a controller and a battery are arranged, and a start button is arranged on the controller, and the motor 6 and the start button are electrically connected to the controller. A control program is written in the controller for controlling the operation of the motor.

[0019] The working principle of the utility model is: multiple lifebuoys are put on the center rod and overlapped on the cart. The lifebuoys are limited by the center rod and the limit rod to prevent the lifebuoys from sliding off, so that more lifebuoys can be transported at one time. If the number is increased, the length of the limit rod can be extended to further increase the number of lifebuoys to be transported. After the lifebuoy is put on the center rod, the motor is started to drive the screw rod to rotate, drive the two sliders to move in the same direction at the same time, and thus drive the limit rod to move, so as to clamp the lifebuoy to prevent it from sliding off, and can adapt to lifebuoys of different diameters.
