DETAILED DESCRIPTION
[0022] 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.
[0023] The utility model provides Figure 1-3 A high-speed opening and closing door for a security inspection passage shown in the figure comprises a sliding door 1 and a fixing plate 8 mounted on the upper end of the sliding door 1;
[0024] A fixed frame 2 is provided on the upper side of the sliding door 1;
[0025] A driving motor 3 is fixedly connected to the inner wall of the left end of the fixing frame 2;
[0026] The driving motor 3 is electrically connected to the external power supply, a plurality of moving wheels 6 are arranged on the left side of the fixing plate 8, and a synchronous belt 5 is arranged on the right side of the driving motor 3 to provide power for the moving wheels 6 to move under the drive of the driving motor 3. After the external access control recognition system recognizes the personnel information, if a pass instruction is issued, the driving motor 3 starts working after receiving the instruction, so that the synchronous belt 5 rotates, and the plurality of moving wheels 6 connected to the synchronous belt 5 rotate in the opposite direction, and the combined sliding door 1 is opened to the left and right sides, so that the personnel can pass through the sliding door 1. If the recognition information is not passed, the driving motor 3 will not start working;
[0027] An abutment plate 15 is provided on the left side of the moving wheel 6. A return spring 14 is fixedly connected to the outer wall of the left end of the abutment plate 15 and close to the upper and lower sides respectively to provide a force for returning the moving wheel 6. When the security personnel carrying the suitcase passes through the sliding door 1 and hits the sliding door 1, the moving wheel 6 tilted by the impact will collide with the abutment plate 15, causing the return spring 14 to contract and exert a force in the opposite direction to quickly reset the moving wheel 6 and prevent the moving wheel 6 from escaping from the synchronous belt 5.
[0028] like Figure 3 As shown, a fixing block 11 is fixedly connected to the inner wall of the upper end of the fixing frame 2 and close to the left and right sides respectively, a plurality of rightward-opening grooves 13 are provided inside the right end outer wall of the fixing block 11 to provide and limit the contraction path of the reset spring 14, a connecting plate 12 is fixedly connected between the left end inner wall of the reset spring 14 and the right end inner wall of the groove 13 to limit the position of the left end of the reset spring 14, and a buffer pad 16 is fixedly connected to the right end outer wall of the abutment plate 15.
[0029] When the return spring 14 contracts, it will contract along the lateral direction of the groove 13 to maintain the stability of the movement of the return spring 14 when it contracts. When the transfer wheel 6 hits the abutment plate 15, it will first contact the buffer pad 16 to prevent the transfer wheel 6 from directly hitting the harder abutment plate 15 and being damaged.
[0030] like Figure 1 and Figure 3 As shown, the buffer pad 16 is made of soft rubber material, the connecting plate 12, the return spring 14 and the abutment plate 15 are fixedly connected by welding, the lateral length of the fixed block 11 is the same as the lateral length between the inner walls at the left and right ends of the fixed frame 2, and a buffer space is reserved between the abutment plate 15 and the fixed block 11.
[0031] The buffer pad 16 made of soft rubber material has a certain buffering effect and can fit the shape of the shifting wheel 6 to avoid damage to the shifting wheel 6. The fixed connection is welded to avoid breakage and separation between the connecting plate 12, the return spring 14 and the abutting plate 15.
[0032] like Figure 1 and Figure 2 As shown, the left end outer wall of the fixed plate 8 is fixedly connected to a positioning shaft 9 which passes through the inside of the moving wheel 6 to the left to limit the position of the moving wheel 6, the right end outer wall of the driving motor 3 is fixedly connected to a driving shaft 4 to drive the synchronous belt 5 to rotate, and a synchronous wheel 7 is fixedly connected between the front and rear end inner walls of the fixed frame 2 near the left side to limit the position of the synchronous belt 5, and the right end outer wall of the fixed plate 8 is fixedly connected to a positioner 10 to limit the moving direction and position of the fixed plate 8.
[0033] The positioning shaft 9 can limit the position of the moving wheel 6 and keep the moving wheel 6 in a stable state during rotation. The driving motor 3 drives the driving shaft 4 to drive the synchronous belt 5 connected to the driving shaft 4 and the synchronous wheel 7 to rotate, so as to drive the moving wheel 6 to rotate and move. The positioner 10 can limit the stable track of the fixed plate 8 when moving.
[0034] The implementation principle of this embodiment is: after the external access control recognition system recognizes the personnel information, if a pass instruction is issued, the drive motor 3 starts working after receiving the instruction, so that the synchronous belt 5 rotates, and the multiple shifting wheels 6 connected to the synchronous belt 5 rotate in opposite directions, and the combined sliding door 1 is opened to the left and right sides, so that people can pass through the sliding door 1. If the recognition information is not passed, the drive motor 3 will not start working. When the security personnel carrying the suitcase passes through the sliding door 1 and hits the sliding door 1, the shifting wheel 6 tilted by the impact will collide with the abutment plate 15, causing the reset spring 14 to contract and issue a force in the opposite direction to quickly reset the shifting wheel 6 to prevent the shifting wheel 6 from escaping from the synchronous belt 5.
[0035] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
