Abstract
Description
Technical Field
[0001] This utility model relates to the field of test tube extraction technology, specifically to a test tube extraction device. Background Technology
[0002] Since test tubes are fragile glass items and cylindrical with curved bottoms, they need to be neatly loaded and stacked to reduce the risk of breakage. Currently, loading racks with insertion holes are commonly used for loading. Test tubes are vertically inserted into the insertion holes of the loading rack to achieve the requirement of neat loading and stacking.
[0003] To facilitate subsequent tube retrieval, this type of loading rack generally has an elastic mechanism installed in the insertion hole. The test tube inserted vertically into the insertion hole is held by the elastic mechanism to maintain stability during loading. When it is necessary to retrieve the tube, simply lift or press the test tube up to squeeze the elastic mechanism, which will gradually separate the test tube from the loading rack, thus meeting the need for convenient tube retrieval.
[0004] However, manually removing the test tube is not only inefficient, but also carries the risk of the test tube falling and breaking when pressed down. Utility Model Content

Detailed Implementation
[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of this utility model are only used to explain this utility model and are not intended to limit this utility model.
[0025] Example
[0026] Please refer to Figure 1 and Figure 2 This embodiment provides a test tube retrieval device, including a base frame 20, which is provided with a lifting joint that can rise or fall vertically; secondly, it includes a retrieval lever 21, which is disposed on the lifting joint, and the bottom of the retrieval lever 21 is used to contact and press down on the test tube to be retrieved loaded on the loading rack, so that the test tube to be retrieved is detached from the loading rack; thirdly, it includes a connecting pipe mechanism, which is disposed on the base frame 20 and located directly below the retrieval lever 21, and the connecting pipe mechanism is used to receive the test tube to be retrieved that is pressed down and detached by the retrieval lever 21.
[0027] This utility model provides a test tube retrieval device. A base frame 20 provides the structural mechanism of the device. A lifting joint and a retrieval lever 21 are included. The lifting joint lowers the retrieval lever 21 to press down on the test tubes loaded on the loading frame, causing the test tubes to detach from the loading frame. A connecting pipe mechanism is provided to catch the detached and falling test tubes, thus stably retrieving them. The entire process is mechanically completed, effectively improving retrieval efficiency compared to manual methods. The connecting pipe mechanism also effectively prevents the test tubes from falling and breaking. Through the cooperation of these features, this test tube retrieval device effectively solves the problems of low efficiency and easy breakage associated with manual retrieval.
[0028] In order to make the tube-retrieving lever 21 have a certain degree of elasticity, a large contact area, and be lightweight enough, the tube-retrieving lever 21 includes a vertical plate 211 and a horizontal plate 212. The top of the vertical plate 211 is connected to the lifting pair, and the bottom is connected to the horizontal plate 212, so that the tube-retrieving lever 21 is L-shaped. The bottom surface of the horizontal plate 212 is used to contact and press down the test tube to be retrieved.
[0029] With the above settings, even if the test tube to be retrieved is tilted to a certain extent, it can be effectively pressed down and corrected by the tube retrieval lever.
[0030] To further optimize the structure of the tube-retrieving lever 21 and improve its stress distribution, the longitudinal lever 211 includes a vertical portion 2111 and an inclined portion 2112. The top of the vertical portion 2111 is connected to the lifting joint. The top of the inclined portion 2112 is connected to the bottom of the vertical portion 2111, and the bottom is connected to the horizontal lever 212. The inclined portion 2112 is set at an obtuse angle to the vertical portion 2111, so that the middle part of the horizontal lever 212 is located directly below the vertical portion 2111.
[0031] To improve the overall structural performance of the tube-retrieving lever 21, the vertical part 2111, the inclined part 2112, and the horizontal piece 212 are integrally formed.
[0032] Since the insertion holes of the loading rack are generally arranged in rows, in order to adjust the horizontal position of the tube picking lever 21 so as to sequentially pick out multiple test tubes arranged in rows, the frame 20 is provided with a translation pair, which can move in the horizontal direction; the lifting pair is provided on the translation pair; the tube picking mechanism is provided on the translation pair.
[0033] It should be noted that the above-mentioned lifting and translation joints can adopt any of the relevant mechanisms in the existing technology. For example, a slide rail and slider structure can be used in conjunction with a motor and track for driving, or a motor and gear set can be used for driving. Alternatively, a cylinder or hydraulic cylinder can be used for pushing and pulling, as long as it can achieve lifting or translation.
[0034] In order to indicate and calibrate the displacement distance of the translation pair, the frame 20 is provided with a channel code plate 22. The channel code plate 22 extends along the moving direction of the translation pair, and the channel code plate 22 is provided with a plurality of code teeth evenly spaced along the length direction. The code teeth are used to indicate and calibrate the displacement distance of the translation pair.
[0035] To further explain the specific structure of the take-up mechanism, the take-up mechanism includes a tube transfer bucket 23 and an opening and closing mechanism; the tube transfer bucket 23 is vertically disposed on the translation pair, the opening of the tube transfer bucket 23 faces vertically upward and is aligned with the center of the bottom of the tube take-up lever 21, and the outlet diameter of the tube transfer bucket 23 is slightly larger than the diameter of the test tube to be taken; the opening and closing mechanism can open or close the outlet of the tube transfer bucket 23.
[0036] With the above setup, the shape of the tube transfer bucket 23 is used to effectively collect and retrieve the falling test tubes.
[0037] It should be noted that the opening and closing mechanism can be any of the existing related mechanisms, such as baffles, hinged doors, or stop bars, as long as it can switch between closed and open. When it is necessary to take out the test tube to be taken out in the tube transfer hopper 23, simply open the opening and closing mechanism, and the test tube to be taken out can slide out from the bottom of the tube transfer hopper 23.
[0038] In order to keep the test tubes to be taken in the tube transfer container 23 in a vertical position so as to facilitate their sliding out during subsequent tube removal, the tube transfer container 23 includes a conical part 231 and a vertical cylindrical part 232. The conical part 231 and the vertical cylindrical part 232 are coaxially connected and communicate with each other. The inner diameter of the vertical cylindrical part 232 is slightly larger than the diameter of the test tube to be taken.
[0039] To further prevent the test tubes to be taken from falling out of the opening of the tube transfer hopper 23, an arc-shaped baffle 233 is provided at the opening of the conical part 231, and the slope of the baffle 233 matches the slope of the conical part 231.
[0040] Preferably, the translation pair is provided with a monitoring optocoupler 24, which is used to monitor the amount of test tubes to be taken loaded on the loading rack.
[0041] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
