Abstract
Description
Technical Field
[0001] This utility model relates to the field of fire door technology, and in particular to a flipper for fire door production. Background Technology
[0002] Fire doors are doors that can meet the requirements of fire resistance stability, integrity and heat insulation within a certain period of time. They are fire-resistant partitions with a certain degree of fire resistance, installed in fire compartments, evacuation stairwells and vertical shafts.
[0003] In the application document CN202022105192.6, the fire door is placed on a platform. Several telescopic hydraulic cylinders 21 simultaneously push the clamps 23 to move along the guide rods 22. The clamps 23 gradually fix the two sides of the wooden door 6. Then, four servo motors 7 are started. The servo motors 7 drive the lead screw 8 to rotate. The lead screw 8 interacts with the threaded hole 12 on the threaded block 11, thereby driving the threaded block 11 to rise. After the wooden door 6 rises to a certain height, motor 14 is started. Motor 14 drives the rotating shaft 15 to rotate. The rotating shaft 15 drives the driving wheel 16 to rotate. The driving wheel 16 drives the driven wheel 17 to rotate. The driven wheel 17 drives the driven shaft 18 to rotate. The driven shaft 18 drives the connecting piece 20 to rotate. The connecting piece 20 drives the telescopic hydraulic cylinders 21 and the wooden door 6 to rotate, thereby realizing the flipping action.
[0004] After the fire door is placed on the placement platform, the lack of a limiting mechanism on the platform prevents the fire door from being positioned in the middle of the two clamps. This results in one side of the clamp extending too far and the other side extending too little after fixing the fire door, thus reducing the flipping effect. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of existing technologies where the lack of a limiting mechanism on the placement platform prevents the fire door from being positioned in the middle of the two clamps, and to propose a flipper for fire door production.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A flipper for fire door production is designed, comprising a base frame, with two symmetrically arranged movable frames slidably connected to the upper end of the base frame. Each movable frame is connected to a flipping mechanism. An electric telescopic rod is fixedly connected to the upper end of the base frame, and a support mechanism is fixedly connected to the upper end of the electric telescopic rod. Fixed seats are connected to both sides of the bottom end of the support mechanism, and a limit member is slidably connected to each fixed seat. A fixed plate is connected between the two limit members, and a threaded hole is opened on the fixed plate. A second mounting plate is fixedly connected to the bottom end of the support mechanism, and a threaded rod is rotatably connected to the second mounting plate, the threaded rod cooperating with the threaded hole.
[0008] Preferably, the flipping mechanism includes a motor, which is fixedly connected to the movable frame. The output end of the motor is fixedly connected to a first mounting plate, and two parallel clamps are fixedly connected to one side of the first mounting plate.
[0009] Preferably, the electric telescopic rod is located between the two movable frames, and the electric telescopic rod and the two movable frames are on the same straight line.
[0010] Preferably, the support mechanism includes a support plate, the bottom end of which is connected to the telescopic end of the electric telescopic rod, a fixed seat and a second mounting plate, and the upper end of the support plate is provided with a plurality of mounting slots, each of which is rotatably connected to a ball.
[0011] Preferably, the limiting member includes a movable plate, which is slidably inserted into a fixed seat. One end of the movable plate is fixedly connected to a fixed plate, and the other end of the movable plate is rotatably connected to a limiting plate. A spring is fixedly connected to the limiting plate, and one end of the spring is fixedly connected to the movable plate.
[0012] Preferably, an anti-collision pad is fixedly connected to the limiting plate, and the anti-collision pad and the support plate are located on the same side.
[0013] The present invention provides a flipper for fire door production, which has the following advantages:
[0014] The fixed plate drives the limiting component to move, and the distance between the limiting component and the support mechanism is adjusted. After the distance is determined, the threaded rod is stopped from rotating. The fire door is placed on the support mechanism and pushed so that one side of the fire door contacts the limiting component. The limiting component limits the fire door, so that the fire door is located in the middle position of the two flipping mechanisms, and the distances of the two sides of the fire door extending out of the support mechanism are the same, thereby improving the flipping effect of the fire door.

Detailed Implementation
[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0021] Example 1: Refer to Figure 1-4 A flipper for fire door production includes a base frame 1. Two symmetrically arranged movable frames 2 are slidably connected to the upper end of the base frame 1. A motor drive 3 for adjusting the distance between the two movable frames 2 is connected to the base frame 1. Each movable frame 2 is connected to a flipping mechanism 4. An electric telescopic rod 5 is fixedly connected to the upper end of the base frame 1. The electric telescopic rod 5 is located between the two movable frames 2 and is on the same straight line as the two movable frames 2. A support mechanism is fixedly connected to the upper end of the electric telescopic rod 5. Fixed seats 9 are connected to both sides of the bottom end of the support mechanism. A limit member is slidably connected to each fixed seat 9. A fixed plate 15 is connected between the two limit members. A threaded hole is opened on the fixed plate 15. A second mounting plate 14 is fixedly connected to the bottom end of the support mechanism. A threaded rod 16 is rotatably connected to the second mounting plate 14 and engages with the threaded hole.
[0022] Work process:
[0023] Rotate the threaded rod 16. With the cooperation of the threaded hole, the fixed plate 15 moves along the length of the threaded rod 16. The fixed plate 15 drives the limiting member to move. Adjust the distance between the limiting member and the support mechanism. After the distance is determined, stop rotating the threaded rod 16.
[0024] After the electric telescopic pole 5 is powered on, it pushes the support mechanism to move upward a set distance. The limiting component moves synchronously with the support mechanism, placing the fire door on the support mechanism. Pushing the fire door causes one side of the fire door to contact the limiting component, which then limits the fire door, positioning it in the middle of the two flipping mechanisms 4. This ensures that both sides of the fire door extend equidistantly from the support mechanism, improving the flipping effect of the fire door.
[0025] After the motor drive unit 3 is started, the two movable frames 2 move towards each other. Each movable frame 2 drives the flipping mechanism 4. After the two flipping mechanisms 4 move towards each other a certain distance, they clamp the fire door. When the fire door is flipped, the electric telescopic rod 5 drives the support mechanism to move downward a set distance. The support mechanism is a certain distance from the lower surface of the fire door. After the two flipping mechanisms 4 are started, they drive the fire door to flip.
[0026] Example 2: Refer to Figure 2 As another preferred embodiment of this utility model, the difference from embodiment 1 is that the flipping mechanism 4 includes a motor 41, which is fixedly connected to the movable frame 2. The motor 41 is a servo motor. The output end of the motor 41 is fixedly connected to a first mounting plate 42. Two parallel clamps 43 are fixedly connected to one side of the first mounting plate 42. After the motor 41 starts, it drives the first mounting plate 42 to rotate. The first mounting plate 42 drives the clamps 43 to rotate. The clamps 43 drive the fire door to rotate, thus flipping the fire door.
[0027] Example 3: In Example 1, when the support mechanism supports the fire door, the fire door experiences significant friction during movement when it is pushed to contact the limiting component, making it difficult to move the fire door. (Refer to...) Figure 4 As another preferred embodiment of this utility model, the difference from embodiment 1 is that the support mechanism includes a support plate 6. The bottom end of the support plate 6 is connected to the telescopic end of the electric telescopic rod 5, the fixed seat 9 and the second mounting plate 14. The upper end of the support plate 6 is provided with a plurality of mounting grooves 7. A ball 8 is rotatably connected in each mounting groove 7. The fire door contacts the upper end of the ball 8. When the fire door is pushed, the ball 8 and the fire door roll into contact, reducing the resistance encountered when pushing the fire door to move, thereby facilitating the movement of the fire door.
[0028] Example 4: In Example 1, when the limiting member limits the fire door, a collision occurs when the fire door contacts the limiting member, which can easily damage the limiting member. (Refer to...) Figure 3-4 As another preferred embodiment of this utility model, the difference from embodiment 1 is that the limiting member includes a movable plate 10, the movable plate 10 is slidably inserted into the fixed seat 9, one end of the movable plate 10 is fixedly connected to the fixed plate 15, the other end of the movable plate 10 is rotatably connected to the limiting plate 12, a spring 11 is fixedly connected to the limiting plate 12, one end of the spring 11 is fixedly connected to the movable plate 10, and an anti-collision pad 13 is fixedly connected to the limiting plate 12. The anti-collision pad 13 and the support plate 6 are located on the same side, and the anti-collision pad 13 is a rubber pad.
[0029] When the fire door is pushed to move, it contacts the limiting plate 12 after moving a certain distance. After the limiting plate 12 is impacted, it pulls the spring 11. The spring 11 generates elastic force after being pulled, and the tension generated by the spring 11 limits and fixes the limiting plate 12, so that the connection between the movable plate 10 and the limiting plate 12 will not break. At the same time, the anti-collision pad 13 reduces the impact intensity between the fire door and the limiting plate 12.
[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
