Detailed Description

The technical solution of the present invention will be further described in detail with reference to the accompanying drawings and embodiments.

As shown in fig. 1 to 7, a toggle type closing device for a box body comprises a box body 1, a toggle switch 2 and an ejecting mechanism 3, wherein a buckle 11 is arranged at the top of one side of the box body 1, the buckle 11 is of an L-shaped structure, and an inclined plane is arranged on the outer side of the top of the buckle 11. The toggle switch 2 is arranged on the front side of the box body 1 close to the buckle 11. When implementing, can fix toggle switch 2 in the drawer bottom or instrument case rear portion one side that need go on fixing to box body 1 to in the pumping process, carry out the joint to box body 1 and fix.

The toggle switch 2 comprises a frame 21, a first spring 22, a switch button 23 and a pulling block 24, wherein the switch button 23 and the pulling block 24 are fixedly connected and can adopt an integrated design. During implementation, the frame 21 is fixed at a proper position according to actual needs, the pulling block 24 is movably connected with the outer side of the frame 21 up and down through the first spring 22, and the bottom of the pulling block 24 is matched and clamped with the buckle 11. Referring to fig. 2, the cross section of the pulling block 24 is trapezoidal, and the bevel edge of the pulling block is matched with the bevel edge of the buckle 11, so that after the box body 1 is pushed to the right position, the pulling block is clamped together by the bevel edge of the buckle 11 and the cutting edge of the pulling block 24.

The ejecting mechanism 3 is arranged at one side of the box body 1 close to the buckle 11, and can be fixed at the rear part of a drawer or the rear part of an instrument box during implementation. Referring to fig. 8, the pop-up mechanism 3 includes an upper cover 31, a lower cover 32, a second spring 33 and a pushing cylinder 34, wherein four ends of the upper cover 31 are provided with fixing holes 311, the upper cover 31 is fixedly connected with the lower cover 32 through the fixing holes 311, and the pop-up mechanism 3 is fixed at a working position as required, so as to conveniently implement a pop-up function. The second spring 33 and the push cylinder 34 are positioned inside the upper cover 31 and the lower cover 32, the second spring 33 is elastically connected with the push cylinder 34, and the end of the push cylinder 34 is in contact with the box body 1.

In the specific implementation of the pop-up mechanism 3, spring slots 321 are respectively formed in the upper cover 31 and the lower cover 32, and the spring slots 321 are square-hole-shaped structures. The second spring 33 and the push cylinder 34 are placed in the spring groove 321, the push cylinder 34 is a square structure, the push cylinder 34 is movably connected with the upper cover 31 and the lower cover 32 in the spring groove 321 through the second spring 33, the end portion of the spring groove 321 is provided with a limiting opening 322, the middle portion of one side of the push cylinder 34 is provided with a spring hole 341, a blocking frame 342 is arranged outside the same side of the push cylinder 34, and the spring hole 341 is sleeved with one end of the second spring 33.

Preferably, in the above embodiment, the outer surfaces of the front and rear sides of the box body 1 are horizontally provided with the slide rails 12. When the box body 1 is pushed out from the bottom of a fixed drawer or the rear part of an instrument box, the box body 1 can stably slide out along a sliding rail in the drawer or the instrument box through the arranged sliding rail 12, so that the situation that the position is deviated when the box body is pushed out is avoided, and the experimental articles stored in the box body 1 are protected.

When the box body 1 is not pushed to the toggle switch 2 and the ejection mechanism 3, the push cylinder in the ejection mechanism 3 is ejected due to the elastic force of the second spring 33, but only one end can be ejected due to the existence of the blocking frame 342 and the limiting opening 322, and the other end with the spring hole 341, which is in contact with the second spring 33, is still in the spring groove 321 in the upper cover 31 and the lower cover 32. When the box body 1 is close to the toggle switch 2 and the ejection mechanism 3 through pushing, the bottom of the shifting block 24 connected with the toggle switch 2 is clamped with the buckle 11 at the top of the box body 1, in the clamping process, the inclined surface of the buckle 11 and the trimming edge of the shifting block 24 are excessive, and then the box body is firmly clamped together. At this time, the second spring is always in a compressed state because the cartridge 1 compresses the push cylinder 34 during the pushing process.

When the box body 1 needs to be pushed out to check articles in the laboratory ware inside, the switch button 23 is pressed manually to be pulled up, the pull block 24 and the buckle 11 are in a separation state, the second spring 33 in the pop-up mechanism 3 pushes the push cylinder 34 out stably, and therefore the box body 1 is pushed out of the original position, and technicians can operate the laboratory ware in the box body 1 in the later period normally.

The utility model discloses in, when pushing into drawer rear portion or instrument case rear portion with box body 1, box body 1 compresses the pusher 34 among the compression pop-up mechanism 3 earlier, and then buckle 11 through box body 1 top carries out the joint with toggle switch 2's pull block 24 and fixes, and when box body 1 was taken out to needs, pulling shift knob 23 made pull block 24 and buckle 11 separate to will push away a 34 steady release through second spring 33, thereby with the ejecting drawer of box body 1 or instrument case. Like this to the box body 1 of depositing the test article, can guarantee that the test article is in good experimental environment, the relevant experimental data of the postrecord of being convenient for.

The above-mentioned embodiments further explain in detail the objects, technical solutions and advantages of the present invention, and it should be understood that the above-mentioned embodiments are only the embodiments of the present invention, and are not intended to limit the scope of the present invention, any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included within the scope of the present invention.
