Technical Field

[0001] The utility model relates to the technical field of analytical instruments, in particular to a door opening mechanism for analytical instruments. Background Art

[0002] Analytical instruments are one of the main branches of scientific instruments. With the development and progress of science and technology, especially the development of life sciences, materials sciences, environmental sciences, energy sciences and civil needs, and the increase in demand for on-site and online testing, the portability, miniaturization and diversification of analytical instruments have become the trend and fashion of the current scientific development of analytical instruments. In traditional laboratories, when an object needs to be tested, it is necessary to manually place the object to be tested into the analytical instrument and then conduct relevant inspections and tests.

[0003] When manually placing the object to be tested, the cover of the testing equipment needs to be opened and closed back and forth. These operations are all done manually. When the amount of samples to be tested is huge, manual labor is required to open the cover back and forth, which adds cumbersome steps. As a result, manual testing is not only inefficient, but also prone to errors under high-intensity repetitive labor, which can easily cause errors in the experimental results.

[0004] Therefore, those skilled in the art provide a door opening mechanism for an analytical instrument to solve the problems raised in the above background technology. Utility Model Content

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] An analytical instrument door opening mechanism comprises a base, and an opening and closing mechanism is arranged above the base;

[0008] The opening and closing mechanism includes an analyzer body, the right side of the analyzer body is movably hinged with an upper cover body, the inner wall of the upper cover body is fixedly connected to a crossbeam support, the inner wall of the crossbeam support is rotatably connected to a retractable push rod, the bottom surface of each retractable push rod is fixedly connected to the upper surface of the base, the upper surface of the analyzer body is provided with a sensing groove, the inner wall of the sensing groove is fixedly connected to an infrared sensor, the front of the analyzer body is fixedly connected to a microprocessor controller, and the microprocessor controller is electrically connected to the infrared sensor and the retractable push rod through wires.

[0009] As a further solution of the utility model: two auxiliary handles are fixedly connected to the inner wall of the base, and a protective door is movably hinged on the left side of the analyzer body.

[0010] As a further solution of the utility model: a sealing ring is fixedly connected to the outer surface of the analyzer body, and a protective shell is fixedly connected to the front side of the analyzer body.

[0011] As a further solution of the utility model: an anti-skid plate is arranged below the base, and the upper surface of the anti-skid plate is in contact with the bottom surface of the base.

[0012] As a further solution of the utility model: two first Velcros are fixedly connected to the bottom surface of the base, and the upper surface of the anti-slip plate is fixedly connected to the second Velcro, and the outer surface of each of the first Velcros is in contact with the outer surface of the second Velcro.

[0013] As a further solution of the utility model: the inner wall of the base is rotatably connected with five auxiliary rollers, and the outer surface of each of the auxiliary rollers is in contact with the inner wall of the anti-slip plate.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] The utility model is provided with a crossbeam support, a retractable push rod, an induction slot, an analyzer body, an upper cover body, a microprocessor controller and an infrared sensor, so that the analyzer body can be automatically opened. The retractable push rod provides power for opening and closing the upper cover body of the analyzer, and the cover is opened and closed smoothly, which reduces the number of manual operation steps.

DETAILED DESCRIPTION

[0023] See also Figure 1-6 A door opening mechanism for an analytical instrument includes a base 1, an opening and closing mechanism 2 is arranged above the base 1, the opening and closing mechanism 2 includes an analyzer body 206, an upper cover body 201 is movably hinged on the right side of the analyzer body 206, a crossbeam support 207 is fixedly connected to the inner wall of the upper cover body 201, two auxiliary handles 6 are fixedly connected to the inner wall of the base 1, a protective door 4 is movably hinged on the left side of the analyzer body 206, and the protective door 4 can be conveniently used to increase the protective structure of the analyzer body 206, and the auxiliary handle 6 can be used to conveniently lift the analyzer sideways.

[0024] The inner wall of the crossbeam support 207 is rotatably connected with a retractable push rod 202, and the bottom surface of each retractable push rod 202 is fixedly connected to the upper surface of the base 1. The upper surface of the analyzer body 206 is provided with a sensing groove 205, and the outer surface of the analyzer body 206 is fixedly connected with a sealing ring 3, and the front of the analyzer body 206 is fixedly connected with a protective shell 5. The sealing ring 3 can increase the sealing performance between the upper cover body 201 and the analyzer body 206, thereby effectively increasing the closing effect.

[0025] An infrared sensor 204 is fixedly connected to the inner wall of the sensing groove 205, and an anti-skid plate 9 is arranged under the base 1. The upper surface of the anti-skid plate 9 contacts the bottom surface of the base 1. The anti-skid plate 9 can increase the anti-slip property of the bottom of the base 1 and effectively ensure the bottom stability of the equipment.

[0026] The front of the analyzer body 206 is fixedly connected to a microprocessor controller 203, the bottom surface of the base 1 is fixedly connected to two first Velcro strips 7, the upper surface of the anti-slip plate 9 is fixedly connected to a second Velcro strip 10, and the outer surface of each first Velcro strip 7 is in contact with the outer surface of the second Velcro strip 10. The first Velcro strip 7 and the second Velcro strip 10 can increase the connection between the anti-slip plate 9 and the bottom of the analyzer body 206 to prevent it from falling off.

[0027] The microprocessor controller 203 is electrically connected to the infrared sensor 204 and the retractable push rod 202 through wires. Five auxiliary rollers 8 are rotatably connected to the inner wall of the base 1. The outer surface of each auxiliary roller 8 is in contact with the inner wall of the anti-slip plate 9. Through the auxiliary rollers 8, the movement effect of the bottom of the analyzer body 206 can be easily increased, thereby increasing the convenience of the equipment.

[0028] The working principle of the utility model is as follows: when in use, the retractable push rod 202 is first connected to the power supply. The retractable push rod 202 can be a cylinder push rod with a cylinder at the bottom, which is connected to the gas source. When the analyzer body 206 needs to be opened, the retractable push rod 202 is extended under the action of the cylinder inside it, thereby pushing the crossbeam support 207 to move, thereby driving the upper cover body 201 of the analyzer body 206 to flip upward through the crossbeam support 207 to realize the action of opening the analyzer body 206. Conversely, the action of closing the analyzer body 206 is realized under the contraction action of the cylinder. During the detection work or the closing process, an infrared sensor 204 is arranged inside the analyzer body 206, and the infrared sensor 204 can directly detect the object above The body is detected. If a hand or other object is detected, the infrared sensor 204 can transmit the detection signal to the microprocessor controller 203, and the microprocessor controller 203 stops the retractable push rod 202 from closing, effectively increasing the overall safety of the opening and closing mechanism 2, and avoiding the opening and closing of the door and other operations to be completed manually, which not only leads to low efficiency of manual detection, but also under high-intensity repetitive labor, manual operation is prone to errors, which can easily cause errors in the experimental results. If it is necessary to move the instrument body, the side of the base 1 can be lifted by the auxiliary handles 6 on both sides, and the anti-slip plate 9 can be taken out through the second Velcro 10. At this time, the auxiliary roller 8 is in contact with the plane, which is convenient for moving the instrument as a whole through the auxiliary roller 8, effectively increasing the translation effect.
