Detailed Description
The utility model will be further described with reference to examples of drawings.
Example 1
As shown in fig. 1-below: the lock catch structure applied to the battery compartment of the handheld meter reading terminal comprises a battery compartment 3, a battery compartment lock catch 3-1 is arranged below the battery compartment 3, a bottom shell 1 is arranged below the battery compartment lock catch 3-1, a sliding lock catch 2 is arranged in the bottom shell 1,
the sliding lock catch 2 comprises a sliding plate 2-5, a connecting rod sliding groove 2-3 is formed in the center of the sliding plate 2-5, the upper portion of the sliding plate 2-5 is connected with a lock catch 2-1 through an elastic angle 2-2, a guide rod 2-4 is arranged at the lower portion of the sliding plate 2-5, a compression spring 4 is sleeved on the guide rod 2-4, and a connecting rod 5 is further arranged outside the compression spring 4.
Wing plates 1-1 are arranged on the left side and the right side of the sliding plate 2-5, and sliding grooves 1-2 matched with the wing plates 1-1 are also arranged on the edge of the bottom shell 1.
The connecting rod 5 is of a C-shaped structure, the lower end of the connecting rod 5 is fixed at the lower end of the guide rod 2-4, and the upper end of the connecting rod is suspended in the connecting rod sliding groove 2-3 and can move along the connecting rod sliding groove 2-3.
The lock catch 2-1 and the elastic angle 2-2 respectively comprise two groups which are symmetrical to each other.
The working principle and working process of the utility model are as follows:
as shown in fig. 4, when the battery compartment 3 is not pushed in, the compression spring 4 is in an uncompressed state, the locker 2-1 is in an opened state, and the elastic angle 2-2 is in a free state.
As shown in fig. 5, when the battery compartment 3 is pushed in, the compression spring 4 is in a compressed state, the lock catch 2-1 is in a closed and locked state, and the elastic angle 2-2 is in a compressed state. At this time, the battery compartment 3 is locked in a fixed position and cannot be pulled out.
As shown in fig. 6 and 7, when the battery compartment 3 is pushed in, the battery compartment buckle 3-1 contacts with the sliding lock catch 2, when the battery compartment 3 is pushed in continuously, the connecting rod 5 slides along the path a-B-C-D-F in the connecting rod sliding groove 2-3, the wing plate 1-1 slides in the sliding groove 1-2, during sliding, when the sliding lock catch 2-1 contacts with the bottom shell 1, the elastic angle 2-3 starts to be compressed, the lock catch 2-1 is limited by the connecting rod 5 when the connecting rod 5 slides to the point F, the sliding lock catch 2 is limited by the connecting rod 5, the lock catch 2-1 is limited in a closed state, the compression spring 4 is in a compressed state, at this time, the battery compartment buckle 3-1 is blocked by the lock catch 2-1, and the battery compartment 3 is fixed and cannot be pulled out.
