Description

Technical Field

[0001] The utility model relates to the technical field of sterilization devices, in particular to an anti-motion alarm triggering device for a heat preservation sterilization box. Background Art

[0002] Incubators and sterilizers must maintain constant temperature and humidity during the insulation and sterilization process, or even a high temperature and high humidity environment. If the incubator or sterilizer is opened in the middle of the process, it is easy to affect the activity of the cultured organisms in the incubator, and for the sterilizer, it will also affect the sterilization effect. Therefore, today's insulation and sterilization boxes need to be equipped with a relatively accurate alarm device.

[0003] However, the existing alarm triggering devices mostly use sensors for triggering, which is costly. At the same time, due to the high humidity environment inside the incubator, moisture leakage can easily affect the sensor, and long-term use will affect its sensitivity and service life.

[0006] The switch trigger seat is installed at the bottom of the screw rod, the switch trigger seat is arranged in the mounting seat, the micro switch is installed on the side of the mounting seat, and the side of the switch trigger seat is provided with a tooth-shaped protrusion that matches the button of the micro switch.

[0007] Furthermore, the switch trigger seat is cylindrical, the upper part is a small-diameter cylinder, and the lower part is a large-diameter cylinder; a protrusion is provided on the side of the large-diameter cylinder, and the protrusion cooperates with the button of the micro switch.

[0008] Furthermore, the mounting seat is a hollow cylinder, the inner diameter of which matches the large diameter cylinder of the switch trigger seat;

[0009] A notch is provided on one side of the mounting seat, a mounting plate is provided at the notch, and the micro switch is fixed on the mounting plate.

[0010] Furthermore, after the switch trigger seat is placed on the mounting seat, it is positioned in the mounting seat through a pressure cover;

[0011] The pressure cover is annular, and the pressure cover and the mounting seat are provided with notches at the same position for placing the micro switch.

[0012] Furthermore, the inner ring of the gland is adapted to the small diameter cylinder of the switch trigger seat, and after being sleeved on the outer ring of the small diameter cylinder, it is fixed to the surface of the mounting seat by screws.

[0013] Compared with the prior art, the advantages of the utility model are: the trigger device of the utility model has a simple structure, and the micro switch is triggered by the rotation of the switch trigger seat. As the rotating shaft part of the box door, the switch of the box door can achieve timely alarm response, and the cost and sensitivity are relatively high. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] Figure 1 This is a schematic diagram of the overall structure of the anti-motion alarm triggering device in the embodiment of the utility model;

[0015] Figure 2 It is a structural schematic diagram of the switch trigger seat in the embodiment of the utility model. DETAILED DESCRIPTION

[0016] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be further described below.

[0017] like Figure 1 As shown, the utility model provides an anti-motion alarm trigger device for a heat preservation sterilization box, comprising a screw 1, a micro switch 2, a mounting seat 3 and a switch trigger seat 4;

[0018] The switch trigger seat 4 is installed at the bottom of the screw rod 1, and the end of the screw rod 1 and the corner of the bottom of the box door serve as a rotation axis. The switch trigger seat 4 is arranged in the mounting seat 3, and the micro switch 2 is installed on the side of the mounting seat 3. The side of the switch trigger seat 4 is provided with a tooth-shaped protrusion 41 that matches the button of the micro switch 2.

[0019] In this embodiment, if Figure 2 As shown, the switch trigger seat 4 is cylindrical, with the upper part being a small diameter cylinder and the lower part being a large diameter cylinder; a protrusion 41 is provided on the side of the large diameter cylinder, and the protrusion 41 matches with the button of the micro switch 2. The mounting seat 3 is a hollow cylinder, and the inner diameter matches with the large diameter cylinder of the switch trigger seat 4; a notch is provided on one side of the mounting seat 3, and a mounting plate is provided at the notch, and the micro switch 2 is fixed on the mounting plate.

[0020] In this embodiment, if Figure 1 As shown, after the switch trigger seat 4 is placed on the mounting seat 3, it is positioned in the mounting seat 3 through the gland 5; the gland is annular, and the gland and the mounting seat 3 are provided with notches at the same position for placing the micro switch 2. The inner ring of the gland is adapted to the small diameter cylinder of the switch trigger seat 4, and after being sleeved on the outer ring of the small diameter cylinder, it is fixed to the surface of the mounting seat 3 by screws.

[0021] The principle of the utility model is that the micro switch 2 is electrically connected to the alarm device, which can be a buzzer or a warning light; when the door is closed, the protrusion 41 on the switch trigger seat 4 just contacts the micro switch 2, and the micro switch 2 is in a closed state and will not trigger the alarm. When the door is opened and rotated, the screw 1 and the switch trigger seat 4 are driven to rotate together, and the protrusion 41 is separated from the micro switch 2, triggering the alarm to respond in time.

[0022] The above are only preferred embodiments of the present invention and do not limit the present invention in any way. Any technician in the relevant technical field, without departing from the scope of the technical solution of the present invention, may make any equivalent replacement or modification to the technical solution and technical content disclosed in the present invention, which shall be deemed as the content of the technical solution of the present invention and still fall within the protection scope of the present invention.
