Detailed Implementation

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] This utility model provides a specimen collection device, such as... Figure 1 As shown, the specimen box includes a specimen box body 1 and a lid 2. The specimen box body 1 has a collection chamber inside. The lid 2 has a fixed base 3 integrally formed inside. The lower end of the fixed base 3 is connected to a connecting rod 4. The middle part of the connecting rod 4 is provided with a positioning ring 5. The lower end of the connecting rod 4 is integrally formed with a collection spoon 6. When the lid 2 is fastened to the upper end of the specimen box body 1, the collection spoon 6 can be suspended and extended into the collection chamber.

[0022] like Figure 2-3 As shown, a separating mechanism is installed on the fixed base 3. The separating mechanism includes a guide frame 7, a separating sleeve 8, and a pressing block 9. The separating sleeve 8 is slidably fitted above the collection spoon 6. The guide frame 7 includes a sliding ring 71, an abutting ring 72, and several guide rods 73. The sliding ring 71 is slidably fitted on the fixed base 3. The guide rods 73 are connected between the sliding ring 71 and the abutting ring 72. A flange ring 10 is provided in the middle of the fixed base 3. The guide rods 73 slide through the flange ring 10. The abutting ring 72 is located below the flange ring 10 and abuts against the upper side of the separating sleeve 8.

[0023] The separating sleeve 8 includes an integrally formed guide sleeve 81 and a separating sleeve 82. The abutting ring 72 abuts against the upper end of the guide sleeve 81. The upper end of the guide ring is provided with a limiting hole that slides and cooperates with the connecting rod 4. The connecting rod 4 slides through the limiting hole. The inner diameter of the guide sleeve is equal to the outer diameter of the positioning ring 5. The guide sleeve 81 is slidably sleeved on the outside of the positioning ring 5. A return spring 11 is connected between the guide sleeve 81 and the positioning ring 5. The inner diameter of the separating sleeve 82 is larger than the width of the collection spoon 6, and it can be used to slide down and cover the outside of the collection spoon 6 to separate the collection spoon 6 and prevent the collection spoon 6 from contacting the inner wall of the specimen box 1.

[0024] The lid 2 has guide slots on both sides corresponding to the fixed base 3. The upper side of the sliding ring 71 has a contact groove corresponding to the guide slot. The pressing block 9 is slidably installed in the guide slot. The pressing block 9 includes an integrally formed sliding part 91 and a wedge part 92. The sliding part 91 slides through the guide slot and the outer end of the sliding part 91 protrudes from the guide slot. The front end of the wedge part 92 is provided with a contact slope. The wedge part 92 is slidably inserted into the contact groove. The contact slope slides against the lower side wall of the contact groove. A pressing spring 12 is connected between the rear end of the wedge part 92 and the inner wall of the lid 2.

[0025] Working principle:

[0026] In this invention, when pulling out and inserting the lid 2, the sliding part 91 of the pressing block 9 protruding from the guide slot is manually pressed simultaneously, causing the pressing block 9 to slide inward as a whole. During the sliding process, the guide frame 7 is pushed downward by sliding on an inclined plane, thereby causing the separating sleeve 8 to slide downward to cover the outside of the collection spoon 6. This can prevent the collection spoon 6 from contacting the specimen box 1 due to improper operation when pulling out and inserting the lid 2. When specimen collection is required, the pressing block 9 is released, and the pressing block 9 is reset under the action of the pressing spring 12. At the same time, the reset spring 11 moves upward against the separating sleeve 8, exposing the collection spoon 6 to facilitate specimen collection. After collection, the pressing block 9 is manually pressed again, and the separating sleeve 8 covers the outside of the collection spoon 6, which can prevent the collection spoon 6 or the specimen from contacting the specimen box 1 when the lid 2 is closed.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
