Description

Technical Field

[0001] This utility model relates to the field of electromagnetic shielding door technology, and in particular to a manual electromagnetic shielding door. Background Technology

[0002] Manual electromagnetic shielding doors have an irreplaceable position due to their suitability for specific needs. In some small, confidential computer rooms, laboratories, and temporary electromagnetic protection areas, where space is limited and the opening and closing frequency is low, if electric electromagnetic shielding doors are used, not only will the large size of the equipment occupy additional space, but the motor and control device will also increase costs and maintenance burdens, and the protective function may be lost in the event of power failure or other emergencies.

[0003] Meanwhile, although manual shielding doors rely on human operation, their shortcomings can be avoided through structural optimization. Problems such as poor sealing and difficulty in opening and closing some early manual doors can be solved by improving the locking mechanism and optimizing the fitting accuracy between the door body and the door frame. Therefore, in electromagnetic protection scenarios, its research and application has become an important choice to supplement the function of electric shielding doors. However, existing electromagnetic shielding doors have a high failure rate, a high failure rate of electronic components, are only suitable for outward-opening doors, have weak anti-theft protection performance, and are affected by unstable voltage and power outages, thus reducing their efficiency. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a manual electromagnetic shielding door, which aims to improve the problems of high failure rate of electromagnetic shielding doors and electronic components in the prior art, as well as the fact that they are only suitable for outward opening doors, have weak anti-theft protection performance, and are affected by unstable voltage and power outages.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a manual electromagnetic shielding door, comprising a door frame, a door leaf disposed in the middle of the front side of the door frame, a locking device disposed at the top of the left front end of the door frame, an upper locking rod disposed at the left front end of the door leaf, a limit seat disposed at the bottom left side of the upper locking rod, a lower locking rod rotatably connected to the bottom of the limit seat, a connecting piece rotatably connected to the bottom end of the lower locking rod, a drive shaft rotatably connected to the inner side of the connecting piece, a fixed seat disposed on the left side of the drive shaft, and a lock head disposed at the top of the fixed seat.

[0006] As a further description of the above technical solution:

[0007] A hinge device is installed between adjacent door panels and door frames.

[0008] As a further description of the above technical solution:

[0009] Locking brackets are fixedly connected to the outer wall of the door frame near the edge.

[0010] As a further description of the above technical solution:

[0011] The left and right ends of the drive shaft are fixedly connected to the bottom of the outer wall of the door.

[0012] As a further description of the above technical solution:

[0013] A manual handrail is rotatably connected to the front left end of the limiting seat.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, a locking device and a hinge device are installed on the vertical beam of the shielded door frame, which works in conjunction with the hinge device connecting the door frame and the door leaf. Then, a manual locking device is installed behind the door leaf, which drives the lower locking rod and the upper locking rod so that the transmission shaft moves in a triangular pattern under the force of the shaft connecting piece, in conjunction with the lock head fixing wheel, to complete the purpose of opening and locking.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see the appendix Figure 1 - Appendix Figure 3 An embodiment of this utility model is provided: a manual electromagnetic shielding door, including a door frame 2, a door leaf 1 is provided in the middle of the front side of the door frame 2, a locking device 12 is provided at the top of the left front side of the door frame 2, an upper locking rod 11 is provided at the left front side of the door leaf 1, a limit seat 10 is provided on the left side of the bottom of the upper locking rod 11, a lower locking rod 8 is rotatably connected to the bottom of the limit seat 10, a connector 5 is rotatably connected to the bottom of the lower locking rod 8, a transmission shaft 4 is rotatably connected to the inner side of the connector 5, a fixed seat 6 is provided on the left side of the transmission shaft 4, and a lock head 7 is provided on the top of the fixed seat 6;

[0024] Specifically, a locking device 12 is provided at the top left side of the front side of the door frame 2. The locking device 12 ensures the safety of the door. When the door leaf 1 is closed, the locking device 12 can accurately lock the door leaf 1 with the corresponding lock hole on the door leaf 1. The limiting seat 10 is a positioning device that can control the movement range of the upper locking rod 11, prevent the upper locking rod 11 from moving excessively during the movement, and ensure the normal operation of the door lock. The limiting seat 10 also has a certain buffering effect, which can reduce the impact force generated by the upper locking rod 11 during the movement, so that the lower locking rod 8 can flexibly follow the movement of the upper locking rod 11 to rotate accordingly, thereby realizing the locking between the bottom of the door leaf 1 and the door frame 2.

[0025] Please see the appendix Figure 2 - Appendix Figure 4 Locking bases 13 are fixedly connected to the outer wall of the door frame 2 near the edge. Hinges 3 are installed between the door leaf 1 and the door frame 2. The left and right ends of the drive shaft 4 are fixedly connected to the bottom of the outer wall of the door leaf 1. A manual handrail 9 is rotatably connected to the front left end of the limit seat 10.

[0026] Specifically, the door frame 2 serves as the stable frame of the entire door, and the locking fixing seat 13 is firmly connected to ensure that the connection between the door leaf 1 and the door frame 2 is tight and stable, without any loosening or jamming. This ensures that the drive shaft 4 and the door leaf 1 become an organic whole. During the door lock operation, the drive shaft 4 can operate accurately and flexibly. It is also connected to the manual handle 9, which is comfortable to hold and easy to operate.

[0027] Working principle: A locking device 12 and a hinge device 3 are installed on the vertical beam of the shielded door frame 2. The hinge device 3 connects the door frame 2 and the door leaf 1. Then, a manual locking device 12 is installed on the back of the door leaf 1. The manual locking device 12 and the manual handrail 9 drive the lower locking rod 8 and the upper locking rod 11, so that the transmission shaft 4 moves in a triangular pattern under the force of the shaft connecting piece 5, in conjunction with the fixed wheel of the lock head 7, to complete the opening and locking purpose. Therefore, the manual locking electromagnetic shielded door does not affect its effect in the absence of power or power failure. It has strong locking force, high stability, low maintenance cost, wide applicability, high flexibility, and improves the efficiency of use.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
