Abstract
Description
Technical Field
[0001] This utility model relates to the field of air defense door testing technology, specifically an air defense door opening and closing force testing device. Background Technology
[0002] Civil defense doors are the entrances and exits of civil defense projects. They are typically characterized by high thickness, strong sealing, and high strength. Some also have small openings for ventilation or temporary personnel access. Currently, civil defense projects are standard equipment in all regions of China. As an important component of civil defense projects, the quality of civil defense doors must be treated with high standards. After production, civil defense doors usually undergo a series of systematic tests. Among them, the opening and closing force of civil defense doors is a very important indicator, reflecting the functionality of civil defense doors. Currently, the installation of civil defense door opening and closing force testing devices is relatively cumbersome. Therefore, a civil defense door opening and closing force testing device is proposed to solve the above problems. Utility Model Content
[0003] (a) Technical problems to be solved
[0004] The purpose of this utility model is to solve the problem that the current air defense door opening and closing force detection device is too cumbersome to fix the air defense door, and to propose an air defense door opening and closing force detection device.
[0005] (II) Technical Solution
[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:
[0007] A device for detecting the opening and closing force of a civil defense door includes an electric telescopic rod. Both the moving and fixed ends of the electric telescopic rod are fixedly connected to U-shaped connectors. The other ends of the two U-shaped connectors are fixedly connected to support seats. Each support seat has a groove at one opposite end, and the inner sides of the two grooves are rotatably connected to a door hinge. A civil defense door is fixedly connected to the right end of the door hinge. A clamping mechanism is provided on the civil defense door, and anchor points are provided on the clamping mechanism for connecting to a traction detection mechanism.
[0008] Based on the above technical solution, the present invention can be further improved as follows.
[0009] Preferably, the clamping mechanism includes a clamping base, which is provided at the right end of the air-raid shelter door. Two fixing plates are fixedly connected to the left end of the clamping base. The two fixing plates are located at the front and rear sides of the air-raid shelter door, respectively. The inner sides of the two fixing plates are threaded with screws. The opposite ends of the two screws abut against the front and rear ends of the air-raid shelter door, respectively. The anchor point is provided at the front end of the clamping base.
[0010] (III) Beneficial Effects
[0011] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:
[0012] This utility model, by setting up an electric telescopic rod, a support seat, and a groove, first activates the electric telescopic rod, causing its moving end to move upward, which in turn moves the upper support seat upward, inserting the door hinge of the air-raid shelter door into the groove of the lower support seat. Then, the moving end of the electric telescopic rod is controlled to retract until the top of the door hinge is inserted into the groove of the upper support seat. The clamping mechanism then clamps the front and rear sides of the air-raid shelter door. Activating the traction detection mechanism allows for the detection of the opening and closing force of the air-raid shelter door. Compared with existing technologies, fixing the air-raid shelter door is simple and quick. Attached Figure Description

[0017] 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.
[0018] In the embodiments, by Figure 1-3 A device for detecting the opening and closing force of a civil defense door is provided, comprising an electric telescopic rod 1, with U-shaped connectors 2 fixedly connected to both the moving end and the fixed end of the electric telescopic rod 1, and support seats 3 fixedly connected to the other ends of the two U-shaped connectors 2, with grooves 4 provided at opposite ends of the two support seats 3, and the inner sides of the two grooves 4 being rotatably connected to a door hinge 5, with a civil defense door 6 fixedly connected to the right end of the door hinge 5, and a clamping mechanism 7 provided on the civil defense door 6, with anchor points 8 provided on the clamping mechanism 7, the anchor points 8 being used to connect to a traction detection mechanism.
[0019] With the above setup, the lower support 3 is fixedly connected to the ground. First, the electric telescopic rod 1 is activated, causing its moving end to move upward, which in turn moves the upper support 3 upward, inserting the door hinge 5 of the air-raid shelter door 6 into the groove 4 of the lower support 3. Then, the moving end of the electric telescopic rod 1 is retracted until the top of the door hinge 5 is inserted into the groove 4 of the upper support 3. The clamping mechanism 7 is used to clamp the front and rear sides of the air-raid shelter door 6. The traction detection mechanism is then activated to detect the opening and closing force of the air-raid shelter door 6. It should be noted that the traction detection mechanism connected to the anchor point 8 consists of a winch, two sections of pull rope, and a force gauge. The winch pulls the pull rope, with the end of the pull rope fixed at the anchor point 8. The two ends of the force gauge are fixed at the ends of the two pull ropes, respectively. When the winch pulls the pull rope, the opening and closing force of the air-raid shelter door 6 can be detected by observing the data from the force gauge. This technology is existing and therefore has not been further expanded.
[0020] Reference Figure 1-3 The clamping mechanism 7 includes a clamping base 71. The clamping base 71 is provided at the right end of the air defense door 6. Two fixing plates 72 are fixedly connected to the left end of the clamping base 71. The two fixing plates 72 are located at the front and rear sides of the air defense door 6 respectively. The inner side of the two fixing plates 72 is threaded with screws 73. The opposite ends of the two screws 73 abut against the front and rear ends of the air defense door 6 respectively. Anchor point 8 is provided at the front end of the clamping base 71.
[0021] With the above-mentioned structural setup, the clamping base 71 is pressed tightly against the right end of the air-raid shelter door 6. The two screws 73 are rotated until the opposite ends of the two screws 73 are in close contact with the front and rear surfaces of the air-raid shelter door 6. The traction detection mechanism can then be activated to detect the opening and closing force of the air-raid shelter door 6.
