The body of eight ally oneself with pipe 6 is arranged in the body and is held seat 111, and the lid 7 of eight ally oneself with pipe 6 is interconnect's lid together, links together between every single pcr pipe of eight ally oneself with pipe 6, and location notch 112 is used for the different hookup location to eight ally oneself with pipe 6, plays the effect of stabilizing eight ally oneself with pipe 6, simultaneously, does benefit to the position of confirming lid 7 and then propulsion unit 2 can carry out the operation of uncapping accurately.
As shown in fig. 4 to 6, the pushing unit 2 includes a pushing member 21, a door opening assembly 22, and a rear pushing projection 23, the pushing member 21 has the door opening assembly 22 fixed to an end thereof, the pushing member 21 has the rear pushing projection 23 fixed to an end thereof remote from the door opening assembly 22, and the rear pushing projection 23 passes through the apparatus casing 4 and protrudes outside the apparatus casing 4. The cover opening assembly 22 comprises a hand grip 221 and a wedge-shaped block 222, a channel 223 capable of accommodating the cover body 7 is formed between the hand grip 221 and the wedge-shaped block 222, and the channel 223 is obliquely arranged from bottom to top. In an initial state, a certain distance is reserved between the rear pushing lug 23 and the front fixing lug 13, a certain distance is reserved between the cover opening assembly 22 and the eight-joint pipe 6, a through groove is formed in the device shell 4, an external force is applied to the rear pushing lug 23, the rear pushing lug 23 moves along the through groove and gradually approaches to the front fixing lug 13, the pushing piece 21 also continuously shortens the distance between the pushing piece and the eight-joint pipe 6 in the moving process of the rear pushing lug 23, a channel 223 formed by the wedge-shaped piece 222 and the hand-grasping piece 221 penetrates through the side portion of the cover body 7, the wedge-shaped piece 222 is in contact with the pipe wall of the eight-joint pipe, the hand-grasping piece 221 covers the upper portion of the cover body 7, and the wedge-shaped piece 222 gradually lifts the cover body 7 in the moving process due to the inclined arrangement of the channel 223, and the cover body 7 is opened. With the above solution, the forces applied to each individual lid are uniform, and there is no risk that one or several lids are subjected to excessive forces which could affect the plurality of tubes. The finger grip 221 and wedge 222 cooperate to receive the opened lid within the channel 223 without the lid being forced to pop out upon opening.
The front fixing lug 13 and the rear propelling lug 23 are arranged along the same straight line, and one side of the front fixing lug 13, which is close to the rear propelling lug 23, is in threaded connection with a limiting adjusting knob 5. The limit adjusting knob 5 can adjust the accessible distance between the front fixing lug 13 and the rear pushing lug 23 by screwing in and out, thereby limiting the degree of pushing the cover body 7 by the wedge-shaped block 222. A plurality of wedge blocks 222 are sequentially arranged along the end of the propelling part 21, and the length of each wedge block 222 is the same. The wedge-shaped blocks 222 with the same length simultaneously reach the cover 7 of the eight-way pipe 6, so that the cover 7 of the eight-way pipe 6 can be removed simultaneously, and the stress applied to the cover corresponding to each pipe body is the same.
The automatic reset device is characterized by further comprising an automatic reset unit 3, wherein the automatic reset unit 3 comprises a first fixing rod 31, a second fixing rod 32 and a tension spring 33, the first fixing rod 31 is fixed on the propelling part 21, the second fixing rod 32 is fixed on the base 12, and the tension spring 33 is installed between the first fixing rod 31 and the second fixing rod 32. The rear pushing cam 23 can be returned to the initial position by the automatic reset unit 3 after moving to the front fixing cam 13 without manually moving the rear pushing cam 23 back to the original position. Because the extension spring 33 is installed between the first fixing rod 31 and the second fixing rod 32, in the initial state, the extension spring 33 is in the extension state, when the rear propelling protrusion 23 moves towards the direction close to the front fixing protrusion 13, the extension spring 33 is gradually compressed, after the cover 7 of the octuple tube 6 is opened, the acting force applied to the rear propelling protrusion 23 is removed, the extension spring 33 will restore the extension state and drive the propelling member 21 to return to the initial position, and further, the automatic reset is realized.
Example two:
as shown in fig. 7 and 8, a plurality of wedge blocks 222 are sequentially arranged along the end of the propelling member 21, and the length of the wedge blocks 222 is gradually increased. The length of the wedge-shaped blocks 222 is set to be inconsistent, and the length difference of the two adjacent wedge-shaped blocks 222 is kept consistent, the technical scheme can gradually and sequentially open each single cover of the eight-way pipe 6, the wedge-shaped blocks 222 sequentially act on the cover body 7 during sequential opening, and the force acting on the eight-way pipe 6 at the same time does not need to be large. Meanwhile, the moving distance of the rear pushing lug 23 can be changed by adjusting the screwing-in or screwing-out length of the limiting adjusting knob 5, so that the number of the covers of the eight-way pipes 6 to be opened is changed, and the eight-way pipe 6 cover opening device is suitable for the situation that the covers of the eight-way pipes 6 are not required to be opened, or the covers of the eight-way pipes 6 are required to be opened in sequence to prevent substances in the eight-way pipes 6 from being exposed in the air in advance and being polluted.
Example three:
as shown in fig. 7-9, the wedge block 222 has flanges 224 extending along its axis to either side. The flanges 224 arranged at the two sides of the wedge-shaped block 222 can reduce the contact area between the wedge-shaped block 222 and the eight-joint pipe orifice when the cover body 7 is opened, and the wedge-shaped block is completely isolated from the pipe orifice, so that the probability of pollution is reduced. If the flange 224 is not provided, the side wall of the wedge-shaped block 222 is in contact with the orifice of the eight-way pipe 6 in a large area, the wedge-shaped block 222 is liable to contaminate the substance in the eight-way pipe 6, and after the flange 224 is provided, since the area of the flange is small and the flange 224 is provided at the lower part of the wedge-shaped block 224, the flange 224 is hardly in contact with the orifice, and the possibility of contamination of the substance in the eight-way pipe 6 is reduced.
The working principle is as follows:
when the front fixing lug 13 and the rear pushing lug 23 are not subjected to external force, the front fixing lug and the rear pushing lug 23 are in a far state, the tension spring 33 is in an extension state, when the rear pushing lug 23 is subjected to external force to enable the rear pushing lug to be close to the front fixing lug 13, the tension spring 33 is stressed to be compressed, the pushing piece 21 and the wedge-shaped block 222 advance towards the eight-joint pipe 6 and simultaneously push the cover body 7 of the eight-joint pipe 6 upwards, and when the cover body 7 is opened, the cover body 7 moves backwards and upwards along a channel 223 between the wedge-shaped block 222 and the hand grip piece 221. When the limit adjusting knob 5 is adjusted to enable the pushing piece 21 to move forwards for a short distance, the cover body 7 can only be half opened, the external force applied to the rear pushing lug 23 is removed, the tension spring 33 pulls the pushing piece 21 to move backwards, and the wedge-shaped block 222 and the hand grip piece 221 are removed from the octuple pipe 6 to enable the cover body 7 to move backwards; when the limit adjusting knob 5 is adjusted to enable the pushing piece 21 to move forwards for a large distance, the cover body 7 can be completely opened, the opened cover body 7 can be directly moved away, then the external force applied to the rear pushing lug 23 is removed, and the tension spring 33 pulls the pushing piece 21 to move backwards to return to the initial position.
Above-mentioned technical scheme has only embodied the utility model discloses technical scheme's preferred technical scheme, some changes that this technical field's technical staff probably made to some parts wherein have all embodied the utility model discloses a principle belongs to within the protection scope of the utility model.
