Description

Technical Field

[0001] The utility model relates to the field of ejection platforms, in particular to an ejection platform with a buffering function. Background Art

[0002] The stage is the space provided for actors to perform in the theater. It can focus the audience's attention on the actors' performance and achieve an ideal viewing effect. Generally, a catapult is set up in the center of the stage so that during the performance, whether it is actors, props or lighting equipment, they can be quickly and safely ejected to the designated position, greatly improving the efficiency of the performance.

[0003] With the existing ejection platform with lifting function, when the staff is ejected from the ejection platform and falls onto the lifting platform, due to the certain height of the ejection, the staff will exert a large pressure on the platform when falling onto the platform, and it is difficult to buffer the pressure. Over time, the platform may be damaged, and the staff's legs will also be subjected to a large reaction force when falling onto the platform, which may cause injury to the staff's legs, thereby reducing the effectiveness of the ejection platform. Utility Model Content

[0004] Based on this, the purpose of the present invention is to provide a ejection platform with a buffering function to solve the technical problem of the inconvenience of buffering the pressure exerted on the platform when the staff falls onto the platform.

[0006] By adopting the above technical solution, when the staff is ejected from the ejection platform and falls onto the buffer plate, the buffer plate will move downward under the force and squeeze the spring rod, causing the spring rod to contract.

[0007] Furthermore, the buffer plate is slidably connected to the movable groove via a movable block, and a rubber pad is provided on the top of the buffer plate.

[0008] By adopting the above technical solution, when the buffer plate moves downward, it can drive the movable block to slide inside the movable groove, thereby improving the stability of the buffer plate when moving.

[0009] Furthermore, the buffer block is slidably connected to the buffer groove, and the outer wall of the buffer plate is fitted with the inner wall of the buffer cavity.

[0010] By adopting the above technical solution, the buffer block can slide inside the buffer groove, thereby squeezing the buffer spring, so that the buffer spring is compressed.

[0011] Furthermore, the rotating plate is rotatably connected to the buffer plate, and the length of the rotating plate is greater than the depth of the buffer cavity.

[0012] By adopting the above technical solution, the rotating plate can be easily rotated, and the rotating plate can push the buffer block to move after rotation.

[0013] Furthermore, a through opening is provided on the top of the ejection platform body, and the length and width of the frame are the same as the length and width of the through opening.

[0014] By adopting the above technical solution, the opening is provided so that the frame and the platform on the scissor lift can be moved out, making it convenient to eject a person from the ejection platform body.

[0015] Furthermore, both sides of the interior of the ejection platform body are provided with limiting grooves, a limiting block is provided inside the limiting groove, and a movable plate is connected to one side of the limiting block.

[0016] By adopting the above technical solution, the setting of the limit block can guide the frame, thereby improving the stability of the movable plate and the frame during movement.

[0017] Furthermore, the top of the movable plate is welded to the bottom of the frame, and the frame and the movable plate are slidably connected to the limiting groove via a limiting block.

[0018] By adopting the above technical solution, when the frame moves, it drives the movable plate to move, and the movable plate drives the limiting block to slide inside the limiting groove.

[0019] Furthermore, a door is hingedly connected to the outer surface of the ejection platform body, and an observation window is provided on the door.

[0020] By adopting the above technical solution, the setting of the observation window makes it easy to observe the interior of the ejection platform body. When a person needs to enter the ejection platform body, he can first open the box door and then enter the interior of the ejection platform body.

[0021] Furthermore, a base is installed at the bottom of the ejection platform body, and protective pads are provided on the inner wall of the through opening and the upper part of the interior of the ejection platform body.

[0022] By adopting the above technical solution, the base can support the ejection platform body, and the provision of the protective pad allows the staff to directly bump into the ejection platform body, thereby protecting the staff.

[0023] In summary, the present invention has the following beneficial effects:

[0024] The utility model is provided with a buffer assembly. When the staff is ejected from the ejection platform main body and falls onto the buffer plate, the buffer plate is squeezed and moves downward, driving the movable block to slide inside the movable groove, and at the same time pushing the rotating plate to rotate, so that the rotating plate pushes the buffer block to slide inside the buffer groove and squeezes the buffer spring, so that the buffer spring is compressed. At the same time, the downward movement of the buffer plate also squeezes the spring rod, so that the spring rod contracts. In this way, the pressure exerted on the staff when they fall onto the buffer plate can be buffered, preventing the scissor lift from being damaged by the large pressure exerted by the staff. In addition, the buffering effect of the buffer spring and the spring rod can protect the legs of the staff, avoiding injuries caused by the reaction force on the legs of the staff.

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0031] The following describes an embodiment of the present invention based on its overall structure.

[0032] Example 1:

[0033] A catapult with a buffer function, such as Figure 1-Figure 4 As shown, it includes a launch platform body 1, a scissor lift 6 is provided inside the launch platform body 1, and a frame 4 is installed on the scissor lift 6, and a buffer assembly 9 is provided on the top of the scissor lift 6. A through opening 3 is opened on the top of the launch platform body 1, and the length and width of the frame 4 are the same as the length and width of the through opening 3. The through opening 3 is set so that the frame 4 and the platform on the scissor lift 6 can be moved out, making it convenient to eject people from the launch platform body 1. The outer surface of the launch platform body 1 is hinged with a box door 10, and the box door 10 is An observation window 11 is provided. The setting of the observation window 11 is convenient for observing the interior of the ejection platform body 1. When someone needs to enter the ejection platform body 1, he can first open the box door 10, and then he can enter the interior of the ejection platform body 1. A base 2 is installed at the bottom of the ejection platform body 1, and a protective pad is provided on the inner wall of the opening 3 and the upper part of the interior of the ejection platform body 1. The base 2 can support the ejection platform body 1. The setting of the protective pad allows the staff to directly bump into the ejection platform body 1, thereby protecting the staff.

[0034] Specifically, the buffer assembly 9 includes a buffer cavity 902 opened at the top of the scissor lift 6, and movable grooves 905 are opened on both sides of the interior of the buffer cavity 902, and movable blocks 904 are provided inside the movable groove 905, and a buffer plate 901 is installed between the two movable blocks 904. Two buffer grooves 908 are opened at the lower part of the interior of the buffer cavity 902, and a buffer spring 906 is provided on one side of the interior of the buffer groove 908. The buffer plate 901 is slidably connected to the movable groove 905 through the movable block 904. A rubber pad is provided on the top of the buffer plate 901. When the buffer plate 901 moves downward, it can drive the movable block 904 to slide inside the movable groove 905, thereby improving the stability of the buffer plate 901 during movement.

[0035] Specifically, a buffer block 907 is installed at one end of the buffer spring 906, and a rotating plate 903 is installed between the buffer block 907 and the buffer plate 901 through a rotating shaft. The rotating plate 903 is rotatably connected to the buffer plate 901. The length of the rotating plate 903 is greater than the depth of the buffer cavity 902, which facilitates the rotation of the rotating plate 903. After the rotating plate 903 rotates, it can push the buffer block 907 to move. The buffer block 907 is slidably connected to the buffer groove 908. The outer wall of the buffer plate 901 fits the inner wall of the buffer cavity 902, so that the buffer block 907 can slide inside the buffer groove 908, and then squeeze the buffer spring 906, so that the buffer spring 906 is compressed. A plurality of spring rods 909 are installed between the buffer plate 901 and the buffer cavity 902. When the staff pops out of the ejection platform and falls on the buffer plate 901, the buffer plate 901 will move downward after being subjected to force and squeeze the spring rod 909, causing the spring rod 909 to shrink.

[0036] Example 2:

[0037] On the basis of the above-mentioned embodiment 1, in order to improve the stability of the frame 4 during movement and prevent the frame 4 from shaking, it is necessary to guide it, so the following structure is provided.

[0038] See Figure 2 and Figure 4 , both sides of the interior of the ejection platform body 1 are provided with limiting grooves 5, and a limiting block 7 is arranged inside the limiting groove 5, and a movable plate 8 is connected to one side of the limiting block 7. The setting of the limiting block 7 is to guide the frame 4, thereby improving the stability of the movable plate 8 and the frame 4 when moving. The top of the movable plate 8 is welded to the bottom of the frame 4, and the frame 4 and the movable plate 8 are both slidably connected to the limiting groove 5 through the limiting block 7. When the frame 4 moves, it will drive the movable plate 8 to move, and the movable plate 8 will drive the limiting block 7 to slide inside the limiting groove 5.

[0039] The working principle of the present invention is as follows: first, when a person needs to be lifted out of the ejection platform body 1, he or she can first open the box door 10, then squat on the platform on the scissor lift 6, and then close the box door 10. When the person needs to be ejected from the ejection platform body 1, the scissor lift 6 can be started, so that the platform of the scissor lift 6 moves up and drives the person to move up, thereby allowing the person to be ejected from the ejection platform body 1; and the equipment required for the ejection platform can also be placed on the platform of the scissor lift 6, and the scissor lift 6 can be used to move the equipment out of the opening 3 when the scissor lift 6 is working;

[0040] At the same time, when the staff is ejected from the ejection platform body 1 and falls on the buffer plate 901, the buffer plate 901 is squeezed and moves downward, driving the movable block 904 to slide inside the movable groove 905, and at the same time pushing the rotating plate 903 to rotate, so that the rotating plate 903 pushes the buffer block 907 to slide inside the buffer groove 908, and squeezes the buffer spring 906, so that the buffer spring 906 is compressed. At the same time, the downward movement of the buffer plate 901 will also squeeze the spring rod 909, so that the spring rod 909 contracts, so that the pressure exerted on the buffer plate 901 by the staff falling on it can be buffered, preventing the scissor lift 6 from being damaged by the large pressure exerted by the staff, and the buffering effect of the buffer spring 906 and the spring rod 909 can protect the legs of the staff.
