[0014] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but they are not intended to limit the present invention.
[0015] like Figure 1 and Figure 2 As shown, a weighing spoon for standard substance dispensing in a preferred embodiment is shown, comprising:
[0016] A sleeve 1, a weighing spoon body 2, a rubber plug 3, a pull rod 4, an elastic member 5 and a cap 6. The sleeve 1 has an accommodating space. Both ends of the sleeve 1 are open. The rubber plug 3 is slidably installed in the accommodating space. One end of the weighing spoon body 2 is installed at one end of the rubber plug 3. The weighing spoon body 2 is arranged in the accommodating space. The other end of the weighing spoon body 2 can be operably extended out of one end of the sleeve 1. A movable window 7 is provided on the outer wall of the sleeve 1. The movable window 7 is arranged near the other end of the sleeve 1. One end of the pull rod 4 is installed on the side wall of the rubber plug 3. The other end of the pull rod 4 extends out of the movable window 7. The pull rod 4 can be operably moved in the movable window 7 along the length direction of the sleeve 1. One end of the cap 6 is installed in the opening at the other end of the sleeve 1. One end of the elastic member 5 is installed at the other end of the rubber plug 3. The other end of the elastic member 5 is installed at one end of the cap 6.
[0017] During actual use, when not in use, the elastic member 5 maintains its original length. At this time, the other end of the weighing spoon body 2 extends out of one end of the sleeve 1. When it is necessary to weigh the standard substance, first weigh a certain amount of the standard substance through the weighing spoon body 2. After the weighing is completed, pull the pull rod 4, and the pull rod 4 drives the rubber plug 3 to move in the direction close to the other end of the sleeve 1 until the weighing spoon body 2 is located in the accommodating space of the sleeve 1 as a whole. Then, after moving to the required position, release the pull rod 4, and the other end of the weighing spoon body 2 extends out of the other end of the sleeve 1 again, and the standard substance can be poured.
[0018] Furthermore, as a preferred embodiment, it further comprises: two hooks 8, one of which is mounted on the other end of the rubber plug 3, and the other hook is mounted on one end of the cap 6, and the two ends of the elastic member 5 are detachably mounted on the two hooks. Furthermore, the rubber plug 3 and the cap 6 are connected to the elastic member 5 through the hooks 8, and when the elastic member 5 needs to be replaced, it is easy to disassemble, which is convenient and quick.
[0019] Further, as a preferred embodiment, the elastic member 5 is a spring.
[0020] Further, as a preferred embodiment, it also includes: a pull ring 9, which is arranged in a semicircular shape, and the two ends of the pull ring 9 are installed on the outer wall of the sleeve 1, and the pull ring 9 is arranged opposite to the movable window 7. Further, when weighing the standard substance, inserting a finger into the pull ring 9 is convenient for pulling the pull rod 4, and it is convenient to keep the sleeve 1 stable, so as to avoid the spillage of the standard substance during weighing. Specifically, insert the middle finger into the pull ring 9, press the cap 6 with the thumb, and pull the pull rod 4 with the index finger.
[0021] Further, as a preferred embodiment, the sleeve 1, the weighing spoon body 2 and the pull ring 9 are all made of antistatic materials. Further, the sleeve 1, the weighing spoon body 2 and the pull ring 9 are made of antistatic materials to avoid static electricity generated during weighing and contamination of the standard substance, thereby ensuring the stability of the standard substance.
[0022] Further, as a preferred embodiment, the movable window 7 is arranged in a long strip shape, and the movable window 7 is arranged along the length direction of the sleeve 1. Further, the width of the movable window 7 is slightly larger than the width of the pull rod 4, which ensures the stability of the pull rod 4 when moving, thereby preventing the weighing spoon body 2 from shaking and causing the standard substance to spill.
[0023] Further, as a preferred embodiment, the movable window 7 includes a first strip hole and a second strip hole that are interconnected, the first strip hole and the second strip hole are arranged in an "L" shape, the first strip hole is extended along the length direction of the sleeve 1, the second strip hole is extended along the circumference of the sleeve 1, and the connection between the first strip hole and the second connection hole is arranged near the other end of the sleeve 1. Further, in actual use, the pull rod 4 first moves along the length direction of the first strip hole, and then enters the second strip hole. When entering the second strip hole, the sleeve 1 is rotated at the same time to avoid the standard substance in the weighing spoon from spilling. The second strip hole is arranged to facilitate the fixing of the pull rod 4 to avoid the pull rod 4 from moving due to the compression of the elastic member 5 during movement, thereby ensuring the stability of the weighing spoon body 2.
[0024] The above description is only a preferred embodiment of the present invention, and does not limit the implementation mode and protection scope of the present invention. For those skilled in the art, it should be aware that all solutions obtained by equivalent substitutions and obvious changes made using the description and illustrations of the present invention should be included in the protection scope of the present invention.
