Description
Technical Field
[0001] This utility model belongs to the field of medical device technology, specifically relating to a test tube storage device. Background Technology
[0002] When conducting medical blood tests, laboratory personnel need to use test tubes to hold the blood samples, and these test tubes need to be placed on test tube racks. Existing test tube racks are mostly made of wood, bamboo, or plastic, with multiple test tube holes to hold multiple test tubes. However, these test tube racks are all open structures, making them easy to accidentally take or replace, and inconvenient to send them to the medical laboratory for testing at the same time. Utility Model Content
[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a highly secure test tube storage device.
[0004] The present invention adopts the following technical solution: A test tube storage device includes a test tube box, a test tube rack, and a switching mechanism. The test tube box includes a box body, a lid rotatably disposed on one side of the box body, and a locking assembly disposed between the box body and the lid. The box body includes a mounting cavity extending inward from one side of the box body for mounting the test tube rack and multiple mounting ports spaced apart at the top of the box body and communicating with the mounting cavity. The lid can open or close the mounting cavity. The test tube rack is detachably disposed within the mounting cavity and includes multiple test tube insertion holes disposed on the test tube rack that are one-to-one with the multiple mounting ports. The switching mechanism is disposed on the box body and includes multiple spring covers respectively disposed on the multiple mounting ports and rotatably connected to the opposite mounting ports via torsion springs, a limiting frame movably disposed in the mounting cavity, and a limiting assembly disposed between the limiting frame and the multiple spring covers to limit the ejection of the multiple spring covers. The limiting frame can move outward after the lid is opened, causing the multiple spring covers to automatically rotate upward under the action of the torsion springs to open the multiple mounting ports.
[0005] Furthermore, the limiting assembly includes a plurality of limiting blocks spaced apart along the length of the limiting frame, elastic blocks respectively disposed on a plurality of spring covers that can abut against the relative limiting blocks, a first guide surface extending obliquely upward from the bottom of the limiting block, and a second guide surface obliquely disposed on the elastic block that can cooperate with the first guide surface. When the spring cover is rotated downward to seal the mounting opening, the elastic block rotates downward under the action of the first guide surface and the second guide surface until its upper end abuts against the lower end of the relative limiting block, thereby sealing the mounting opening of the opposite spring cover.
[0006] Furthermore, the elastic block includes a fixed block extending outward from the opposite surface of the spring cover and the mounting cavity, an abutment block movably disposed on the fixed block, and a reset spring disposed between the fixed block and the abutment block. The second guide surface is formed obliquely upward from the bottom of the abutment block. When the elastic block rotates downward with the spring cover, the first guide surface and the second guide surface slide and fit together, causing the reset spring to be squeezed and deformed. When the first guide surface slides off the second guide surface, the first guide surface disengages from the second guide surface, causing the reset spring to reset. The upper end of the abutment block abuts against the lower end of the limiting block.
[0007] Furthermore, the limiting frame includes a movable rod movably disposed within the mounting cavity and a plurality of limiting crossbars disposed on the movable rod at intervals along its length. The movable rod is vertically disposed in the middle of the limiting crossbars, the mounting opening is disposed between two adjacent limiting crossbars, and the limiting block extends outward from the opposite surface of the limiting crossbar and the interior of the mounting cavity.
[0008] Furthermore, the mounting cavity includes multiple guide seats with an inner top surface for the moving rod to pass through, and two guide rails disposed on both sides inside the mounting cavity and respectively cooperating with the ends of the limiting crossbars. The multiple guide seats are respectively located between two adjacent limiting crossbars.
[0009] Furthermore, the test tube rack includes a bracket movably disposed within the mounting cavity and a first tray and a second tray arranged sequentially from top to bottom on the bracket. The test tube insertion holes extend downward from the top surface of the first tray to the second tray. A plurality of the test tube insertion holes are spaced apart along the length direction of the first tray. Two movable grooves are arranged opposite each other on the bottom surface of the mounting cavity, and two movable blocks are provided at the bottom of the bracket, which are respectively opposite to the two movable grooves.
[0010] Furthermore, the locking assembly includes a first latch extending outward from the mounting cavity, a first lock sleeve disposed on the other side of the lid through which the first latch passes, and a digital combination lock disposed on the lid to engage with the first latch.
[0011] Furthermore, the box also includes a handle provided on the box for carrying the test tube box.
[0012] As can be seen from the above description of this utility model, compared with the prior art, the beneficial effects of this utility model are as follows: This application, through the cooperation of the test tube box, the test tube rack detachably set in the installation cavity, and the switch mechanism set on the box body, can sequentially close multiple installation ports or open all installation ports at once. After multiple spring covers are sealed and fixed in multiple installation ports, the sampled test tubes are stored in the test tube box, realizing a closed storage structure. At the same time, the test tubes in the installation cavity can only be taken out by opening the box cover, realizing a storage method in which only authorized specific personnel can open the test tube box, reducing the probability of test tube racks or test tubes being replaced or mistakenly taken, and improving the security of the test tube box.

[0028] There are two specific ways to set the locking component 13 in this application, see reference. Figures 1 to 3 As shown, the first embodiment of the locking assembly 13 of this application includes a first locking buckle 131 extending outward from the mounting cavity 15, a first locking sleeve 132 disposed on the other side of the cover 12 through which the first locking buckle 131 passes, and a digital combination lock 133 disposed on the cover 12 and cooperating with the first locking buckle 131; specifically, the digital combination lock 133 is a three-digit sliding digital combination lock commonly used in the prior art, and its specific structure and location will not be further described here.
[0029] Reference Figures 10 to 11 As shown, the second embodiment of the latch in this application includes a second latch 134 extending outward from the mounting cavity 15, a second lock sleeve 135 on the other side of the cover 12 through which the second latch 134 passes, a lock hole 136 on the second latch 134, and a padlock 137 that cooperates with the lock hole 136. Specifically, the padlock 137 is a conventional mechanical lock type that can be opened with a corresponding key in the prior art. Its principle and specific selection will not be further described here.
[0030] There are two specific ways to set the handle 14 in this application, see below. Figures 1 to 4 As shown, the first embodiment of the handle 14 of this application includes two rotating rods 141 disposed opposite to each other on both sides of the box body 11 and a first U-shaped rod 142 whose two ends are respectively rotatably connected to the two rotating rods 141.
[0031] Reference Figures 10 to 11 As shown, the second embodiment of the handle 14 of this application includes two second U-shaped rods 143 disposed opposite to each other on the top of the box body 11 and two rotating seats 144 disposed on the top of the box body 11 and rotatably connected to the two ends of the opposite second U-shaped rods 143. The ends of the second U-shaped rods 143 can be embedded in the opposite rotating seats 144 and rotatably connected by a rotating shaft 145.
[0032] The test tube rack 2 is detachably installed in the mounting cavity 15 and includes multiple test tube insertion holes 21 that are one-to-one with multiple mounting ports 16. Specifically, the test tube rack 2 includes a bracket 22 movably installed in the mounting cavity 15 and a first support plate 23 and a second support plate 24 arranged sequentially from top to bottom on the bracket 22. The test tube insertion holes 21 extend downward from the top surface of the first support plate 23 to the second support plate 24, and the multiple test tube insertion holes 21 are spaced apart along the length of the first support plate 23. Test tubes can be stably placed on the first support plate 23 and the second support plate 24 through the corresponding test tube insertion holes 21. Furthermore, two moving grooves 17 are provided opposite to each other on the bottom surface of the mounting cavity 15, and two moving blocks 25 are provided at the bottom of the bracket 22 that are respectively opposite to the two moving grooves 17. The test tube rack 2 and the mounting cavity 15 are slidably connected by the moving blocks 25 and the moving grooves 17.
[0033] The switching mechanism 3, mounted on the housing 11, includes multiple spring covers 31 respectively mounted on multiple mounting openings 16 and rotatably connected to the opposite mounting openings 16 via torsion springs; a limiting frame 32 movably mounted in the mounting cavity 15; and a limiting component 33 positioned between the limiting frame 32 and the multiple spring covers 31 to restrict the ejection of the multiple spring covers 31. The limiting frame 32 can move outward after the housing cover 12 is opened, causing the multiple spring covers 31 to automatically rotate upward under the action of the torsion springs, opening the multiple mounting openings 16. Through the mutual cooperation between the multiple spring covers 31, the limiting frame 32, and the limiting component 33, the multiple mounting openings 16 can be closed sequentially or all mounting openings 16 can be opened at once. 1. After being sealed and fixed within multiple mounting ports 16, the test tubes in the mounting cavity 15 can only be removed by opening the box cover 12, thus achieving a closed storage structure. Simultaneously, only authorized personnel can open the test tube box 1, reducing the probability of the test tube rack 2 or test tubes being replaced or mistakenly taken, thereby improving the security of the test tube box 1. Specifically, the limiting component 33 includes multiple limiting blocks 34 spaced along the length of the limiting frame 32, elastic blocks 35 respectively disposed on multiple spring covers 31 that abut against the corresponding limiting blocks 34, a first guide surface 36 extending obliquely upward from the bottom of the limiting block 34, and a second guide surface obliquely disposed on the elastic block 35 that cooperates with the first guide surface 36. 37; When the spring cover 31 rotates downward to seal the mounting port 16, the elastic block 35 rotates downward under the action of the first guide surface 36 and the second guide surface 37 until its upper end abuts against the lower end of the relative limiting block 34, thus sealing the mounting port 16 of the opposite spring cover 31; further, the elastic block 35 includes a fixed block 351 extending outward from the opposing surfaces of the spring cover 31 and the mounting cavity 15, an abutment block 352 movably disposed on the fixed block 351, and a return spring 353 disposed between the fixed block 351 and the abutment block 352, and the second guide surface 37 is formed inclined upward from the bottom of the abutment block 352; when the elastic block 35 rotates downward with the spring cover 31, the first guide surface 36 and the second guide surface 37 abut against the lower end of the relative limiting block 34, thus sealing the mounting port 16 of the opposite spring cover 31; The sliding contact of surface 37 causes the return spring 353 to be compressed and deformed. When the first guide surface 36 slides off the second guide surface 37, the first guide surface 36 disengages from the second guide surface 37, causing the return spring 353 to return to its original position. The upper end of the abutment block 352 abuts against the lower end of the limiting block 34. Furthermore, the limiting frame 32 includes a movable rod 321 movably disposed in the mounting cavity 15 and a plurality of limiting crossbars 322 disposed on the movable rod 321 at intervals along its length. The movable rod 321 is vertically disposed in the middle of the limiting crossbars 322. The mounting opening 16 is disposed between two adjacent limiting crossbars 322. The limiting block 34 extends outward from the opposite surface of the limiting crossbar 322 and the interior of the mounting cavity 15.Furthermore, the mounting cavity 15 includes multiple guide seats 18 with their inner top surface for the moving rod 321 to pass through, and two guide rails 19 disposed on both sides inside the mounting cavity 15, respectively cooperating with the ends of the limiting crossbars 322. The multiple guide seats 18 are respectively located between two adjacent limiting crossbars 322.
[0034] The specific working principle of this application is as follows: In the initial state, the box body 11 and the box cover 12 are rotatably connected, the mounting cavity 15 is in the open state, multiple spring covers 31 are located above the corresponding mounting openings 16, and the limiting bracket 32 can be pulled outwards. In use, first place the test tube rack 2 inside the mounting cavity 15, then rotate the box cover 12. The locking assembly 13 then fixes the box cover 12 to the box body 11. At this time, the mounting cavity 15 is in the closed state, and the test tube rack 2 is fixedly installed inside the mounting cavity 15. After medical personnel or patients collect samples, a single sampling test tube is inserted through the mounting opening 16 into the corresponding test tube holder. Inside hole 21, manually rotate spring cover 31 downwards to seal the opposite mounting port 16, which provides temporary protection for a single test tube. After all mounting ports 16 are closed, all test tubes are sealed and stored in test tube box 1. When test tube box 1 is delivered to the laboratory, authorized personnel can open the locking assembly 13 to remove test tube rack 2. At the same time, simply pull the limiting frame 32 outwards to rotate multiple spring covers 31 upwards to reset them. There is no need to manually open them one by one. The operation is simple and convenient for medical staff to use next time.
[0035] In summary, by utilizing the above-mentioned technical solution of this utility model, through the cooperation between the test tube box 1, the test tube rack 2 detachably disposed in the mounting cavity 15, and the switch mechanism 3 disposed on the box body 11, multiple mounting ports 16 can be closed sequentially or all mounting ports 16 can be opened at once. When multiple spring covers 31 are sealed and fixed in multiple mounting ports 16, the sampled test tubes are stored in the test tube box 1, realizing a closed storage structure. At the same time, the test tubes in the mounting cavity 15 can only be taken out by opening the box cover 12, realizing a storage method in which only authorized specific personnel can open the test tube box 1, reducing the probability of the test tube rack 2 or test tubes being replaced or mistakenly taken, and improving the security of the test tube box 1.
[0036] The above description is merely a preferred embodiment of the present utility model, and therefore cannot be construed as limiting the scope of the present utility model. All equivalent changes and modifications made in accordance with the scope of the present utility model application and the contents of the specification should still fall within the scope of the present utility model application.
