Referring to fig. 1 to 4, an embodiment of the utility model provides a door locking structure 100 for being mounted to an external device, where the external device includes a first body 210 and a second body 220 that can be relatively buckled with each other, and the door locking structure includes a locking member 110, a locking member 120, a first elastic member 130, a toggle member 140, a pushing member 150, and a second elastic member 160. The locking member 110 is fixed to the second body 220. The locking member 120 is slidably disposed in the first body 210, and when the first body 210 is engaged with the second body 220, the locking member 120 contacts the locking member 110 and slides. The first resilient member 130 is used to urge the locking member 120 to slide toward the locking member 110 after the first body 210 is fastened to the second body 220 to lock the locking member 110. The toggle member 140 is used to urge the locking member 120 to slide away from the latch member 110 under an external force to release the latch member 110. The pushing member 150 is slidably disposed on the first body 210, and when the first body 210 is buckled with the second body 220, the pushing member 150 contacts the locking member 110 and slides. The second elastic member 160 is used for deforming along with the sliding of the pushing member 150 when the first body 210 is buckled with the second body 220, and is also used for driving the pushing member 150 to slide after the locking member 120 releases the locking piece 110 so as to push the second body 220 out.
According to the door-locking structure 100 provided in the above embodiment, when the first body 210 is locked with the second body 220, the locking piece 110 contacts with the locking piece 120 and drives the locking piece 120 to slide away from the locking piece 110, and meanwhile, the locking piece 110 contacts with the pushing piece 150 and drives the pushing piece 150 to slide, and the second elastic piece 160 contacting with the pushing piece 150 is deformed. After the locking member 120 slides a certain distance, the locking member 110 no longer exerts a sliding force on the locking member 120, and the locking member 120 abuts against the locking member 110 under the action of the first elastic member 130 to lock the first body 210 and the second body 220. When opening the door, the user contacts the toggle member 140, and the toggle member 140 urges the locking member 120 to slide away from the locking member 110 and release the locking member 110. Since the locking member 110 loses the constraint of the locking member 120, the locking member 110 is moved away from the first body 210 by the second resilient member 160 and the pushing member 150. Compared with the prior art, the door locking structure 100 provided by the embodiment does not need to be manually pulled after the lock is released, and is more convenient for a user to operate.
Of course, in this embodiment, the first body 210 and the second body 220 may be slidably engaged or may be hinge engaged.
Specifically, two ends of the first elastic element 130 respectively abut against the first body 210 and the toggle element 140, and two ends of the second elastic element 160 respectively abut against the first body 210 and the push element 150.
Preferably, the first elastic member 130 and the second elastic member 160 are both coil springs.
Referring to fig. 2-4, in a specific embodiment of the present invention, the locking member 110 has a position-limiting hole 110a, the locking member 120 has a position-limiting post 122 adapted to the position-limiting hole 110a, and after the first body 210 and the second body 220 are fastened, the position-limiting post 122 is inserted into the position-limiting hole 110a under the action of the first elastic member 130. The design of the position-limiting post 122 and the position-limiting hole 110a in this embodiment can further improve the locking capability of the locking member 120, especially when the first body 210 and the second body 220 are of a hinge-locked structure.
In one embodiment, the end of the locking member 110 adjacent to the locking member 120 is provided with a guiding surface for abutting against the position-limiting post 122 to drive the locking member 120 to slide.
Preferably, the guide surface is a cambered surface.
Referring to fig. 4, in another embodiment of the present invention, the door locking structure 100 further includes a shielding member 170 for limiting the position of the locking member 120 so that the locking member 120 is away from the locking member 110. Thus, when the first body 210 is engaged with the second body 220, the locking member 110 does not contact the locker 120, thereby shielding the locking function of the cover locker 120.
In a specific embodiment, a spherical protrusion is fixedly disposed on the locking member 120, a through slot 170a adapted to the protrusion is disposed on the shielding member 170, and when the protrusion moves to the through slot 170a along with the locking member 120, the protrusion is inserted into the through slot 170a to fix the locking member 120. It will be appreciated that the bulbous protrusion configuration may facilitate access to the channel 170a, and that the protrusion that fits into the channel 170a may be sized to adjust the force required by the user to actuate the toggle 140.
In a specific embodiment, a third elastic member 175 is further disposed in the through slot 170a, and the third elastic member 175 is configured to abut against the convex portion. In this way, the protrusion can be facilitated to exit the through slot 170 a.
In another specific embodiment, the door locking structure 100 further includes a first magnetic member 192 fixed on the first body 210 and a second magnetic member 194 fixed on the second body 220, and when the first body 210 is buckled with the second body 220, the first magnetic member 192 is magnetically connected with the second magnetic member 194. It should be noted that, after the shielding member 170 shields the locking function of the locking member 120, the first body 210 and the second body 220 can be connected through the first magnetic member 192 and the second magnetic member 194. This provides the user with a variety of locking means.
Referring to fig. 3 and 4, in another embodiment of the present invention, a pushing member 150 is slidably disposed on the locking member 120. Therefore, an additional structure for fixing the pushing member 150 is not required to be added in the first body 210, and the compactness of the structure is improved.
In a more specific embodiment, the locking member 120 is provided with a guide block 124, the pushing member 150 is provided with a guide groove 150a, and the guide block 124 is slidably disposed in the guide groove 150a, although the reverse is also possible.
In addition, in order to make the locking structure better fixed in the first body 210, the door locking structure 100 further includes a pressing block 180 adapted to each component thereof.
Another embodiment of the present invention further provides a syringe pump 200, which includes the door locking structure 100 provided in any of the above embodiments, and the first body 210 and the second body 220.
The above disclosure is only for the purpose of illustrating the preferred embodiments of the present invention, and it is therefore to be understood that the utility model is not limited by the scope of the appended claims.
