The specific working principle and process of the feeding locking device provided by the invention will be described in detail.
As shown in fig. 3 and 4, the loading lock device 100 is in an initial state, in which the lock structure 101 slides along the rail groove 2 and coincides with the bottom plate 1. In this embodiment, the feeding clamping block 3 and the first link mechanism 5 are respectively located on the front and back sides of the sliding plate 41, so as to provide a placement platform for the test piece. Specifically, the surface of the feeding clamping block 3 is defined as the front surface, and the feeding clamping block 3 passes through the sliding plate 41 and is respectively and fixedly connected with the left sliding block 52 and the right sliding block 53, i.e. the feeding clamping block 3 can synchronously slide with the left sliding block 52 and the right sliding block 53.

As shown in fig. 5, when the slide plate 41 is manually pulled, at this time, the second rail 43 slides out of the rail groove 2, the first rail 42 also slides out of the second rail 43, and when the locking member 44 located on the first rail 42 slides out of the second rail 43, the free end 44a of the locking member 44 is ejected and extends and tilts in the opposite direction of the sliding of the first rail 42 into the second rail 43, the feeding clamping block 3 is manually pushed, the left slider 52 slides in the first direction (i.e., arrow E direction) so that the ram 64 collides with the free end 44a of the locking member 44, and the locking member 44 is positioned in an inclined manner between the first rail 42 and the second rail 43 (as shown in fig. 6), thereby locking the first rail 42 and the second rail 43. When the locking member 44 is specifically an elastic sheet, it is required that the free end of the elastic sheet exceeds the port of the second rail 43, and the free end is away from the first rail 42 and contacts the port of the second rail 43 while abutting against the ram 64, but not limited thereto. At this time, since the locking member 44 abuts against the pressing head 64 and the middle portion of the pressing head 64 is rotatably connected to the transmission member 62, the elastic member 63 connected to the other end of the locking member 44 abutting against the pressing head 64 will be in a stretched state by the principle of leverage, thereby maintaining the pressing head 64 in a balanced state, while the rotational connection point of the second link 55 and the third link 56 is in contact with the transmission member 62. The first guide rail 42 and the second guide rail 43 are locked by the pressure of the second connecting rod 55 and the third connecting rod 56 to the transmission member 62, the tension of the elastic member 63 to the pressing head 64, and the elastic force of the locking member 44 to the pressing head 64.

As shown in fig. 8, the test piece is placed in the product placement area 8, the feeding clamping block 3 is manually pushed to clamp the test piece, the left slider 52 is driven to slide in the second direction (i.e. the arrow F direction), at this time, the left slider 52 and the right slider 53 are close to each other, the first link mechanism 5 is in a folded state and drives the second link mechanism 6 to move, so that the pressing head 64 is pressed against the free end 44a of the locking piece 44, and the free end 44a moves in the direction close to the first guide rail 42 and is gradually attached to the first guide rail 42. At this time, the lock 44 is flattened by the ram 64, and the lock on the first rail 42 and the second rail 43 is released (as shown in fig. 9). Subsequently, the slide plate 41 is pushed so that the slide plate 41 slides into the rail groove 2, the final state is as shown in fig. 3, 4,
The locking structure 101 provided by the invention comprises a mechanism to be locked 4, a first link mechanism 5 and a second link mechanism 6.
