It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of the present disclosure.

[0021] Embodiment 1

[0022] An automatic induction alarm injection pump, such as Figure 1As shown (and referenced Figure 2-3 ), comprising a body 1, a pushing mechanism 4 and a tube groove 2 for installing a syringe are arranged on one side of the body 1, and the pushing mechanism 4 is installed on one side of the tube groove 2. A locking assembly 3 is arranged on the tube groove 2. The locking assembly 3 comprises a fixing seat 31, a locking seat 32 and a curved rod 33, one end of the curved rod 33 is rotatably connected to the fixing seat 31. The other end of the curved rod 33 is installed on the locking seat 32; a locking groove 326 is provided on the locking seat 32.

[0023] Furthermore, if Figure 2 As shown, a spring slot 321 is provided on the side wall of the lock slot 326. A lock tongue 322 and a pull rod 323 are installed in the spring slot 321, and one end of the pull rod 323 is connected to one end of the lock tongue 322. A spring 324 is provided between the spring slot 321 and the lock tongue 322, and the spring 324 is sleeved on the pull rod 323. In a natural state, the spring 324 pushes the lock tongue 322 to move to the outside of the spring slot 321.

[0024] Furthermore, if Figure 3 As shown, a locking hole 331 is provided at one end of the arc rod 33 away from the fixing seat 31. The locking hole 331 cooperates with the locking tongue 322 to install the other end of the arc rod 33 in the locking groove 326. Further, a magnet 325 is provided at the bottom of the locking seat 32. Further, the arc rod 33 is made of metal material. The magnet 325 can attract the arc rod 33 to quickly lock in the locking groove 326, and has the function of reinforcing the fixation of the arc rod 33, thereby reinforcing the installation of the syringe in the tube groove 2.

[0025] Furthermore, a rubber pad 332 is provided on the side of the arc rod 33 facing the tube groove 2. The rubber pad 332 is elastic and cooperates with the arc rod 33 to press the syringe so that the syringe is more firmly fixed in the tube groove 2. Furthermore, a clamping groove 21 is provided on the side of the tube groove 2 close to the pushing mechanism 4. The clamping groove 21 is used to install the support ear of the syringe to prevent the syringe from moving relative to the tube groove 2.

[0026] Working principle:

[0027] When installing the syringe, the arc rod 33 is rotated downward, and then the syringe is placed in the tube groove 2, and the ear of the syringe is correspondingly clamped in the clamping groove 21. Then the arc rod 33 is rotated upward, and one end of the arc rod 33 is attracted by the magnetic force of the magnet 325 and quickly slides into the locking groove 326. When one end of the arc rod 33 quickly slides into the locking groove 326, the locking tongue 322 is squeezed into the spring groove 321. When one end of the arc rod 33 completely enters the locking groove 326, the locking tongue 322 corresponds to the position of the locking hole 331, and the locking tongue 322 is moved into the locking hole 331 by the elastic force of the spring 324, so that the locking tongue 322 cooperates with the locking hole 331, and one end of the arc rod 33 is locked in the locking groove 326. If the syringe needs to be taken out, the pull rod 323 is pulled to move the locking tongue 322 into the spring groove 321, and then the arc rod 33 is rotated to rotate it out of the locking groove 326, and then the syringe can be taken out.

[0028] The utility model conveniently and quickly takes out and fixes the syringe from the tube groove through the rotational cooperation between the fixing seat, the locking seat and the cambered rod, and prevents the syringe from being easily rubbed off or moved by a person carelessly, so that the syringe is deflected or dropped from the injection pump.
