Description

TECHNICAL FIELD

[0001] The application relates to the technical field of oil sample storage, and particularly relates to a portable constant-temperature oil sample storage box. BACKGROUND

[0002] The constant-temperature oil sample storage box mainly comprises a heating system, a cooling system, a temperature control system and a heat preservation layer. During the storage of oil products, the heating and cooling system can automatically adjust according to the temperature change of the oil products, so that the oil products can always be kept in a set temperature range. The temperature control system can accurately control the temperature of the oil products, and ensures that the oil sample does not change in quality during the storage process due to the temperature change.

[0003] Although the existing constant-temperature oil sample storage box can provide a constant-temperature and constant-humidity environment for the oil sample tube to a certain extent, the contact ability of the oil sample tube with the environment is crossed, and the hot flow and the cold flow flow in the sample storage hole with or without the oil sample tube, which causes resource waste.

[0038] The circular oil storage area 5 is fixedly arranged in the box 1.

[0039] The strip-shaped oil storage area 6 is fixedly arranged in the box 1, and the upper end of the strip-shaped oil storage area 6 is flush with the upper end of the circular oil storage area 5, and the heating and refrigeration device 7 can provide hot flow and cold flow to the circular oil storage area 5 and the strip-shaped oil storage area 6.

[0040] Based on the above technical scheme, when the oil storage pipe is placed in the box 1, the lock catch 4 is opened, the end cover 3 is rotated, the oil storage pipe is placed in the corresponding circular oil storage area 5 and strip-shaped oil storage area 6, the circular oil storage area 5 and the strip-shaped oil storage area 6 are communicated with the heating and refrigeration device 7, then the end cover 3 is closed, and the end cover 3 and the box 1 are closed through the lock catch 4; when the oil storage pipe is taken out from the box 1, the lock catch 4 is opened, the end cover 3 is rotated, the oil storage pipe to be used is taken out from the corresponding circular oil storage area 5 and strip-shaped oil storage area 6, and the circular oil storage area 5 and the strip-shaped oil storage area 6 are disconnected with the heating and refrigeration device 7.

[0041] Based on the above technical scheme, the circular oil storage area 5 and the strip-shaped oil storage area 6 are communicated with the heating and refrigeration device 7 after the oil storage pipe is placed, so that the oil sample can quickly reach the set temperature, the response speed and accuracy of temperature control are improved, and only when the oil storage pipe is placed, the hot flow contacts the oil storage pipe through the communication of the circular oil storage area 5 and the strip-shaped oil storage area 6 with the heating and refrigeration device 7, so that invalid heating during no load is avoided, the safety of the equipment is improved, and energy is saved.

[0042] In a possible implementation, the circular oil storage area 5 includes a circular oil storage tank 51 fixedly arranged in the box 1, at least four circular oil storage holes 52 are uniformly arranged in the circular oil storage tank 51, a take-out and storage flow control unit 55 is symmetrically arranged on the circular oil storage tank 51 at the lower end of the circular oil storage hole 52, a column cylinder 53 located in the circular oil storage hole 52 is arranged on the take-out and storage flow control unit 55, and a circular damping layer 54 is fixedly arranged in the column cylinder 53.

[0043] In one possible implementation, the strip-shaped oil storage area 6 includes a strip-shaped oil storage tank 61 fixedly disposed within the housing 1. At least three strip-shaped oil storage holes 62 are evenly arranged inside the strip-shaped oil storage tank 61, and the oil storage and flow control unit 55 is symmetrically installed on the strip-shaped oil storage tank 61 located at the lower end of the strip-shaped oil storage holes 62. A strip tube 63 located inside the strip-shaped oil storage holes 62 is placed on the oil storage and flow control unit 55. A strip-shaped shock-absorbing layer 64 is fixedly disposed inside each strip tube 63. By placing the strip tube 63 and the strip-shaped shock-absorbing layer 64 inside the strip-shaped oil storage holes 62, the strip-shaped shock-absorbing layer 64 can provide a buffering and shock-absorbing effect for the oil storage tube.

[0044] In one possible implementation, both the circular oil storage tank 51 and the strip-shaped oil storage tank 61 are provided with symmetrical connecting holes 511. The connecting holes 511 are connected to the heating and cooling device 7. The heat flow and cold flow generated by the heating and cooling device 7 can be guided to the circular oil storage hole 52 and the strip-shaped oil storage hole 62 through the connecting holes 511.

[0045] In one possible implementation, a circular oil storage tube 13 may be installed inside the circular damping layer 54 on the storage and flow control unit 55, and a strip oil storage tube may be installed inside the strip damping layer 64 on the storage and flow control unit 55. The upper ends of the circular oil storage tube 13 and the strip oil storage tube may be sealed to prevent the oil sample inside the circular oil storage tube 13 and the strip oil storage tube from flowing out after being placed in the housing 1 and then moved.

[0046] In one possible implementation, the upper end of the end cap 3 is hinged with a handle, which allows the constant temperature oil sample box to be moved, thus improving its portability.

[0047] In one possible implementation, the access control unit 55 includes:

[0048] The guide rail 550 is configured as two rails, and a slider 551 is movably provided at the upper end of each rail. A limit seat 552 is fixedly provided between the sliders 551.

[0049] The bottom hinge shaft 553 has one end hinged to the limiting seat 552, and the other end is fixedly provided with a base plate 554.

[0050] A deflection shaft 555 is hinged to the limiting seat 552. A plug 556 is fixedly provided on one side of the deflection shaft 555 away from the limiting seat 552, and a pawl 557 is fixedly provided on the other side of the deflection shaft 555 away from the limiting seat 552. Each pawl 557 is fixedly provided with a plastic soft pad. A connecting shaft 558 is hinged at the center of the deflection shaft 555, and the connecting shaft 558 is hinged to the inner side of the bottom hinge shaft 553 near the bottom plate 554.

[0051] The support spring 559 is fixedly installed at the lower end of the bottom hinge shaft 553.

[0052] Through the above technical solution, after the base plate 554 is pressed down and deflected, the base plate 554 drives the connecting shaft 558 and the deflection shaft 555 to deflect, and the blockage 556 deflects inward; after the corresponding circular oil storage pipe 13 and strip oil storage pipe on the base plate 554 are removed, the base plate 554 deflects during the reset process of the support spring 559, and the blockage 556 deflects outward.

[0053] In one possible implementation, the guide rail 550 is fixedly disposed in the circular oil storage hole 52 and the strip-shaped oil storage hole 62 respectively, and the lower end of the support spring 559 is fixedly disposed with the circular oil storage tank 51 located at the bottom of the circular oil storage hole 52 and the strip-shaped oil storage tank 61 located at the bottom of the strip-shaped oil storage hole 62 respectively.

[0054] Using the above technical solution, a circular oil storage tube 13 is placed inside the column cylinder 53, and a strip-shaped oil storage tube is placed inside the strip cylinder 63. The column cylinder 53, the circular damping layer 54, and the circular oil storage tube 13, together with the strip cylinder 63, the strip-shaped damping layer 64, and the strip-shaped oil storage tube, press down on the bottom plate 554. The claws 557 are engaged on the outside of the column cylinder 53 and the strip cylinder 63, which on the one hand prevents the clamping force from acting directly on the circular oil storage tube 13 and the strip-shaped oil storage tube, and on the other hand provides positioning for the circular oil storage tube 13 and the strip-shaped oil storage tube. Then, the end cap 3 is closed, and the end cap 3 is locked to the housing 1. When the lock is closed, the slider 551 descends along the guide rail 550, and the support spring 559 is compressed. When retrieving the circular oil storage tube 13 and the strip oil storage tube from the housing 1, the end cover 3 is rotated. During the process of the support spring 559 recovering its deformation, the slider 551 rises along the guide rail 550, the limit seat 552 rises, and the column cylinder 53, the circular shock-absorbing layer 54, and the circular oil storage tube 13 extend out of the circular oil storage hole 52. The strip cylinder 63, the strip shock-absorbing layer 64, and the strip oil storage tube extend out of the strip oil storage hole 62. They do not need to be manually pulled out, which greatly improves the convenience of retrieval.

[0055] In one possible implementation, the plugs 556 are all provided corresponding to the connecting holes 511. A circular oil storage tube 13 is placed inside the cylinder 53, and the bottom plate 554 is deflected, so that the plugs 556 are away from the connecting holes 511. After the circular oil storage tube 13 and the strip oil storage tube at this position are taken out, the bottom plate 554 is deflected during the reset process of the support spring 559, and the plugs 556 close the connecting holes 511 at this position.

[0056] In one possible implementation, a circular limiting groove 5541 is provided on the base plate 554 away from the bottom hinge shaft 553. The circular limiting groove 5541 can lock the bottom of the circular oil storage tube 13 for positioning. A shock-absorbing layer is fixedly provided on the upper end of the base plate 554 to protect the bottom of the circular oil storage tube 13 and the strip oil storage tube, thereby enabling all-round shock absorption protection for the circular oil storage tube 13 and the strip oil storage tube.

[0057] In specific implementation, when placing the circular oil storage tube 13 and the strip oil storage tube inside the housing 1, unlock 4, rotate end cap 3, place column cylinder 53 and circular damping layer 54 inside circular oil storage hole 52, place strip cylinder 63 and strip damping layer 64 inside strip oil storage hole 62, place circular oil storage tube 13 inside column cylinder 53, and place strip oil storage tube inside strip cylinder 63. Column cylinder 53, circular damping layer 54, and circular oil storage tube 13 are connected to strip cylinder 63 and strip oil storage tube 64. The shock-absorbing layer 64 and the strip oil storage pipe press down on the bottom plate 554. The bottom plate 554 drives the connecting shaft 558 and the deflection shaft 555 to deflect. The block 556 moves away from the connecting hole 511. The heat or cold flow generated by the heating and cooling unit 7 enters the circular oil storage hole 52 and the strip oil storage hole 62 along the connecting hole 511. Then the end cover 3 is closed and the end cover 3 is sealed to the box 1 by the lock 4. At this time, the slider 551 descends along the guide rail 550 and the support spring 559 is compressed.

[0058] When retrieving the circular oil storage tube 13 and the strip oil storage tube from the housing 1, the latch 4 is opened, the end cover 3 is rotated, and during the process of the support spring 559 restoring its deformation, the slider 551 rises along the guide rail 550, the limit seat 552 rises, the column cylinder 53, the circular damping layer 54 and the circular oil storage tube 13 extend out of the circular oil storage hole 52, and the strip cylinder 63, the strip damping layer 64 and the strip oil storage tube extend out of the strip oil storage hole 62. After retrieving the circular oil storage tube 13 and the strip oil storage tube at this position, the bottom plate 554 deflects during the reset process of the support spring 559, blocking 556 and sealing the connecting hole 511 at this position.

[0059] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
