Description

Technical Field

[0001] This utility model specifically relates to the field of power-free automatic password sealing cap technology, and more specifically to a power-free automatic password sealing cap for a sampling sealing barrel. Background Technology

[0002] In fields such as environmental monitoring, geological exploration, and biological sample collection, it is often necessary to collect and temporarily store various samples on-site. Sampling containers, as key equipment for sample preservation and transportation, have caps whose performance directly affects the safety and integrity of the samples. Traditional sampling container caps have many drawbacks.

[0003] Most of these containers use simple mechanical fasteners or ordinary locks, offering limited sealing performance. In complex environments, they are prone to sample leakage and contamination. Furthermore, ordinary locks offer weak anti-theft and anti-tampering capabilities, leaving samples vulnerable to accidental opening and malicious replacement, making them unsuitable for scenarios with stringent requirements for sample authenticity and uniqueness. Some container lids with encryption functions use electronic combination locks, which rely on batteries for operation. However, during long-term field sampling or operations in remote areas, power supply is difficult, and the electronic locks are prone to failure due to battery depletion, failing to continuously guarantee sealing security. Simultaneously, the poor stability of electronic components under extreme temperature and humidity conditions further reduces encryption reliability.

[0004] Traditional sealing caps are cumbersome to open and close, and lack convenient and safe designs for small-volume sample extraction. If a portion of the sample needs to be taken, the cap often needs to be fully opened, which disrupts the overall sealed environment and increases the probability of sample contamination. Furthermore, the sealing caps of different sampling buckets have poor compatibility, which is not conducive to the standardized configuration and management of equipment. Utility Model Content

The lock beam bracket 31 is provided with a combination wheel positioning core 32 and a lock beam 33. The combination wheel positioning core 32 is provided with multiple combination wheel groups 34 in a rectangular array. The lock beam 33 is slidably connected to the inner side of the latch connecting seat 25 and the latch connecting seat 14.

[0035] The inner side of the lock beam 33 is slidably connected to the auxiliary locking rod 38. The auxiliary locking rod 38 is provided on the lock beam bracket 35. The lock beam bracket 35 is also provided with a password unlocking pin 36. The password unlocking pin 36 is slidably connected to the password wheel positioning core 32. The password unlocking pin 36 is provided with multiple unlocking pin linkage teeth 37 in a rectangular array. The unlocking pin linkage teeth 37 are connected to the inner side of the password wheel positioning core 32.

[0036] By adopting the above technical solution, the mechanical combination lock 3 does not require a power source during use, making it suitable for complex environments such as field operations and areas without electricity. The encryption structure composed of components such as the combination wheel group 34 and the combination unlocking pin 36 increases the difficulty of cracking, prevents the sample from being illegally opened or tampered with, and ensures the security of the sample.

[0037] In this embodiment, the locking connecting seat 14 is located on the outside of the barrel reinforcing ring 12, and two sets of connecting ear seats 13 are also provided on the outside of the barrel reinforcing ring 12. The barrel reinforcing ring 12 is fixedly connected to the upper outside of the sampling barrel body 11.

[0038] The upper inner side of the sampling barrel body 11 is connected to the lower end of the encapsulation cover body 21. A rubber sealing ring 22 is provided on the lower outer side of the encapsulation cover body 21. A connecting seat 24 is provided on the upper outer side of the encapsulation cover body 21. A connecting arm 23 is rotatably connected to the connecting seat 24. The lower end of the connecting arm 23 is rotatably connected to two sets of connecting ear seats 13 respectively.

[0039] The locking connector 25 is located on the outside of the packaging cover body 21; the upper end of the packaging cover body 21 is provided with a connecting ear 26 and a connecting ear plate 27 respectively, and a sample extraction port 28 is provided between the connecting ear 26 and the connecting ear plate 27.

[0040] The sample extraction port 28 is connected to the sealing cap 211. A rubber sealing ring 212 is provided on the outer side of the lower end of the sealing cap 211. A connector 210 and a connecting ear plate 213 are respectively provided on the upper end of the sealing cap 211.

[0041] The other end of the connector 210 is fixedly connected to the rotating rod 29, and the rotating rod 29 is rotatably connected to the connecting ear seat 26; a top combination lock 214 is connected between the connecting ear plate 213 and the connecting ear plate 27.

[0042] By adopting the above technical solution, the sampling bucket body 11 and the bucket lid body 21 are sealed by rubber sealing ring 1 22, and the sample extraction port 28 is sealed by rubber sealing ring 212. The double sealing structure effectively blocks the external environment, prevents the sample from being contaminated or leaked, and ensures the stability of the sample storage environment.

[0043] The connecting arm 23, connecting ear seat and other connecting structures enable the bucket lid to be quickly closed and positioned. The sealing cap 211 of the sample extraction port 28 and the top combination lock 214 ensure safety while facilitating the extraction of small amounts of samples as needed, thus balancing safety and ease of operation.

[0044] The working principle of this utility model is as follows: the sampling barrel body 11 and the barrel cover body 21 are initially sealed by the rubber sealing ring 22; the connecting arm 23 rotates to connect the connecting seat 24 and the connecting ear seat 13 to assist the sealing cover body 21 in closing and positioning; the locking connecting seat 14 and the locking connecting seat 25 cooperate with the mechanical combination lock 3 to complete the locking of the barrel body and the cover.

[0045] In the mechanical combination lock 3, the combination wheel set 34 is arranged in an orderly manner on the combination wheel positioning core 32.

The sliding of the lock beam 33 and the auxiliary locking rod 38 locks or unlocks the first lock connecting seat 14 and the second lock connecting seat 25. The auxiliary locking rod 38 also enhances the locking stability of the lock beam 33.

[0046] The sample extraction port 28 is sealed by the sealing cover 211, and the rubber sealing ring 212 ensures the sealing performance; the rotating rod 29 and the linkage connector 210 control the opening and closing of the sealing cover 211; the top combination lock 214 connects the connecting ear plate 27 and the connecting ear plate 213, which provides secondary encryption for the extraction port, while facilitating the extraction of small amounts of sample and reducing the large-area contact of the sample with the external environment.

[0047] When in use, the mechanical combination lock 3 requires no power supply and is suitable for complex environments, such as field operations and areas without electricity. The encryption structure composed of components such as the combination wheel group 34 and the combination unlocking pin 36 increases the difficulty of cracking, prevents the sample from being illegally opened or tampered with, and ensures the security of the sample.

[0048] The sampling bucket body 11 and the bucket lid body 21 are sealed by a rubber sealing ring 22, and the sample extraction port 28 is sealed by a rubber sealing ring 212. The double sealing structure effectively blocks the external environment, prevents the sample from being contaminated or leaking, and ensures the stability of the sample storage environment.

[0049] The connecting arm 23, connecting ear seat and other connecting structures enable the bucket lid to be quickly closed and positioned. The sealing cap 211 of the sample extraction port 28 and the top combination lock 214 ensure safety while facilitating the extraction of small amounts of samples as needed, thus balancing safety and ease of operation.
