Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of sample barrels, in particular, relates to a sample barrel capable of improving sealing performance and being quickly disassembled. BACKGROUND

[0002] The sample barrel is used for storing various samples to be detected and sampled, and is usually composed of a barrel body and a barrel cover. However, in the process of storing samples, some powdery or granular sample raw materials are easily dropped into the barrel opening during loading. If the barrel cover is directly installed and closed without attention, the sample raw materials will exist in the connection between the barrel body and the barrel cover, thereby greatly reducing the sealing performance of the sample barrel.

[0003] In addition, in order to enhance the sealing performance of the connection between the barrel body and the barrel cover, the existing sample barrel usually sets a silica gel product such as a sealing strip or a sealing ring, and some also sets a magnet to make the connection more closely. However, this will cause a certain resistance when the connection between the barrel body and the barrel cover is disassembled, thereby making the disassembly of the sample barrel cover more difficult.

[0025] Figure 1 is a perspective view of a sample bucket according to an embodiment of the present application.

[0026] Referring to Figure 1 , a sample bucket according to an embodiment of the present application comprises a bucket body 1, two fixing blocks 2 are fixed symmetrically on the periphery of the bucket mouth of the bucket body 1, a bucket cover 3 is arranged above the bucket mouth of the bucket body 1, two connecting blocks 4 are fixed symmetrically on the periphery of the bucket cover 3, and the two fixing blocks 2 are connected to the two connecting blocks 4 one by one respectively.

[0027] In addition, magnets (not labeled) that are magnetically attracted to each other are arranged in the edge of the bucket mouth of the bucket body 1 and the edge of the bucket cover 3 that corresponds to the edge of the bucket mouth of the bucket body 1. Further, sealing strips (not labeled) are arranged in the edge of the bucket mouth of the bucket body 1 and the edge of the bucket cover 3 that corresponds to the edge of the bucket mouth of the bucket body 1. When the bucket body 1 and the bucket cover 3 are completely closed, the two sealing strips correspond and fit, thereby achieving a sealed closure between the bucket body 1 and the bucket cover 3.

[0028] Figure 2 is another perspective view of a sample bucket according to an embodiment of the present application. In Figure 2 , in order to clearly show the internal structure of the bucket cover 3, the top plate of the bucket cover 3 is removed. Figure 3 is a structural view of the bottom plate of the bucket cover according to an embodiment of the present application.

[0029] Referring to Figure 2 and Figure 3 , a large gear 7 is rotatably fitted in the bottom of the bucket cover 3, small gears 8 are rotatably fitted in the bottom of the two connecting blocks 4, the two small gears 8 are engaged with the large gear 7, and two L-shaped cleaning plates 11 are symmetrically and slidingly fitted on the outer ring of the large gear 7, and the two L-shaped cleaning plates 11 correspond to the bucket mouth of the bucket body 1.

[0030] The lower part of the bucket cover 3 of the present embodiment is provided with an annular track 5, and the two L-shaped cleaning plates 11 are slidingly fitted in the annular track 5. The outer ring of the large gear 7 is symmetrically provided with two sliding grooves (see Figure 6), two L-shaped cleaning plates 11 are respectively slidably fitted in the two sliding grooves, two recesses 6 are symmetrically arranged at the edge below the barrel cover 3, and the lower ends of the two L-shaped cleaning plates 11 correspond to the two recesses 6 respectively.

[0031] When the barrel cover 3 moves downward to close, the rotation of the large gear 7 drives the two L-shaped cleaning plates 11 to move synchronously, so that the two L-shaped cleaning plates 11 slide along the annular track 5, the upper ends of the two L-shaped cleaning plates 11 are slidably fitted in the two sliding grooves, until the lower ends of the L-shaped cleaning plates 11 are retracted into the recesses 6, so that the lower side of the L-shaped cleaning plates 11 is flush with the lower side of the barrel cover 3, thereby the L-shaped cleaning plates 11 complete the cleaning of the barrel opening, and the barrel cover 3 is closed.

[0032] Figure 4 is another perspective view of the sample barrel according to the embodiment of the present application. In Figure 4 , in order to show the internal structure of the fixed block 2, the fixed block 2 on the right side in Figure 4 is removed. Figure 5 is a sectional view of the sample barrel according to the embodiment of the present application. Figure 4 without removing the fixed block. Figure 6 is an enlarged view of the A area in Figure 5 .

[0033] Referring to Figures 4 to 6 together, the middle part of the pinion 8 is threadedly fitted with a screw rod 9, the middle part of the fixed block 2 is provided with a circular groove 12 corresponding to the lower end of the screw rod 9, and a disassembling assembly is arranged in the fixed block 2, the disassembling assembly is clamped with the circumferential side of the lower end of the screw rod 9, and corresponds to the connection between the barrel body 1 and the barrel cover 3.

[0034] One aspect of the application of the embodiment is as follows: first, when the barrel cover 3 is installed, the barrel cover 3 is placed directly above the barrel body 1, then the lower ends of the two screw rods 9 are respectively inserted into the middle parts of the two circular grooves 12, at this time the disassembling assembly in the fixed block 2 is clamped with the screw rod 9, then the barrel cover 3 is pressed downward, at this time the two screw rods 9 are respectively threadedly fitted with the two pinions 8 and drive the two pinions 8 to rotate in the same direction, so that the two pinions 8 are engaged with the large gear 7, then the large gear 7 drives the two L-shaped cleaning plates 11 to rotate synchronously along the barrel opening above the barrel body 1, and the sum of the rotation numbers of the two L-shaped cleaning plates 11 is one circle, thereby the cleaning of the barrel opening is realized, and at the same time the two L-shaped cleaning plates 11 are gradually retracted into the barrel cover 3, at this time the barrel body 1 and the barrel cover 3 are completely closed, and the closing connection relationship between the two is strengthened by the two magnets arranged therebetween, thereby the installation of the barrel cover 3 is realized.

[0035] When the bucket cover 3 needs to be disassembled, the disassembling assembly needs to be rotated first, so that the disassembling assembly cancels the clamping relationship of the screw rod 9, and extends into the connection between the barrel body 1 and the bucket cover 3, so that a gap is generated between the barrel body 1 and the bucket cover 3, thereby reducing the attraction between the two magnets, and the bucket cover 3 can be directly manually lifted to realize disassembly. It should be noted that all electrical equipment involved in the present application can be powered by a battery or an external power supply.

[0036] With reference to the foregoing Figure 5 , the top of the bucket cover 3 of the present embodiment is rotationally fitted with a rotating disc 20, a rectangular cylinder is fixed between the upper side of the large gear 7 and the rotating disc 20, a first spring 10 is fixed between the upper end of the L-shaped cleaning plate 11 and the lower side of the rotating disc 20, and the first spring 10 is located inside the rectangular cylinder, and the upper end of the L-shaped cleaning plate 11 is slidingly fitted in the rectangular cylinder.

[0037] When the large gear 7 rotates, the rotating disc 20 is synchronously driven to rotate by the two rectangular cylinders, the upper end of the L-shaped cleaning plate 11 is slidingly fitted in the rectangular cylinder and exerts pressure on the first spring 10, the first spring 10 is in a reduced compression state, and then the elastic rebound force of the first spring 10 will always make the lower end of the L-shaped cleaning plate 11 adhere to the bucket opening, thereby completing the cleaning work.

[0038] As shown in Figure 5 and Figure 6 , the lower half of the screw rod 9 of the present embodiment is a smooth surface corresponding to the circular groove 12, and two clamping grooves are symmetrically provided on the radial side of the lower half of the screw rod 9. When the barrel body 1 and the bucket cover 3 need to be installed, the lower half of the two screw rods 9 is directly aligned and inserted into the circular groove 12 in the upper middle part of the fixed block 2, and the smooth surface of the lower half of the screw rod 9 can reduce the resistance, thereby being more conveniently and smoothly placed in the circular groove 12.

[0039] In addition, the disassembling assembly includes a channel 13 provided in the inside of the fixed block 2, a short clamping plate 14 and a long clamping plate 15 slidingly fitted in the inner wall of the channel 13, a clamping block 19 fixed to the opposite inner sides of the short clamping plate 14 and the long clamping plate 15, a trapezoidal block 16 located at the bottom of the channel 13, a screw rod 17 threadedly fitted in the middle part of the trapezoidal block 16, and a triangular block 18 fixed to the outer side of the upper end of the long clamping plate 15.

[0040] When the barrel cover 3 needs to be disassembled, first rotate the screw rod 17, so that the screw rod 17 and the trapezoidal block 16 threadedly drive the trapezoidal block 16 to move upward, at this time the trapezoidal block 16 is located between the short clamping plate 14 and the long clamping plate 15 and extrudes them, so that the short clamping plate 14 and the long clamping plate 15 move relatively as a whole in parallel and reverse, thereby changing the distance between the short clamping plate 14 and the long clamping plate 15, so that they relatively far away, then the two clamping blocks 19 on the relatively inner side of the short clamping plate 14 and the long clamping plate 15 exit the clamping groove to cancel the clamping relationship of the screw rod 9, and at the same time the triangular block 18 on the upper end of the long clamping plate 15 extends into the connection between the barrel body 1 and the barrel cover 3, so that a slight gap is generated between the connection of the barrel body 1 and the barrel cover 3, reducing the attraction between the magnets, and finally the barrel cover 3 can be directly opened manually.

[0041] The relatively inner end of the upper side of the two clamping blocks 19 is arc-shaped, and the two clamping blocks 19 correspond to the two clamping grooves respectively, and the second spring (not shown) is fixed between the relatively outer side of the short clamping plate 14 and the long clamping plate 15 (i.e. the side of the short clamping plate 14 facing away from the long clamping plate 15, and the side of the long clamping plate 15 facing away from the short clamping plate 14) and the inner wall of the channel 13. The two isosceles sides of the trapezoidal block 16 correspond to the lower ends of the short clamping plate 14 and the long clamping plate 15 respectively, the screw rod 17 is rotatably connected to the middle part below the fixed block 2, and the long clamping plate 15 is located on the side close to the barrel body 1.

[0042] When the barrel cover 3 needs to be installed, the lower half of the screw rod 9 is aligned and extends into the circular groove 12 in the middle part above the fixed block 2, then the lower end of the screw rod 9 contacts and extrudes the arc-shaped surface on the upper side of the two clamping blocks 19, at this time the second spring is in a compressed state, when the screw rod 9 is completely inserted into the circular groove 12, the clamping block 19 is aligned with the clamping groove, at this time the elastic rebound force of the second spring drives the clamping block 19 to extend into the clamping groove to generate a clamping relationship, thereby completing the installation of the barrel cover 3, at this time the trapezoidal block 16 should be located at the bottom of the channel 13 and exit between the short clamping plate 14 and the long clamping plate 15.

[0043] The triangular block 18 of the embodiment is slidably connected to the upper part of the fixed block 2, and the inclined corner of the triangular block 18 corresponds to the connection between the barrel body 1 and the barrel cover 3. When the short clamping plate 14 and the long clamping plate 15 relatively far away cancel the clamping of the screw rod 9, the long clamping plate 15 will move towards the side close to the barrel body 1, then the long clamping plate 15 drives the inclined corner of the triangular block 18 to extend into the connection between the barrel body 1 and the barrel cover 3, thereby generating a slight gap between the connection of the barrel body 1 and the barrel cover 3.

[0044] In summary, in the sample bucket according to the embodiment of the present application, through the screw rod arranged in the middle of the pinion and the two L-shaped cleaning plates arranged below the bucket cover, when the bucket cover is installed downward, the two screw rods drive the two pinions and the gear to engage, thereby synchronously driving the two L-shaped cleaning plates to rotate and clean the bucket opening above the bucket body, preparing for the subsequent closing of the bucket cover, effectively reducing the situation that materials fall off at the bucket opening, and further ensuring the sealing performance when the bucket body and the bucket cover are closed. Further, by arranging the magnet at the connection between the bucket body and the bucket cover, the quick alignment and installation of the bucket cover are improved. Further, by arranging the disassembly assembly in the fixing block, the screw rod can be quickly connected or disconnected, and when the bucket cover is disassembled, the disassembly assembly can also extend into the connection between the bucket body and the bucket cover, thereby reducing the force generated when the magnets attract each other, and further facilitating the disassembly of the bucket cover.
