[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] See also Figure 1 and Figure 2 The utility model provides a technical solution: a lock body adjustable baffle, comprising a baffle panel 1 fixed on the lock body and an adjustable dust shield box 4 mounted in the baffle panel 1, the baffle panel 1 can slide horizontally relative to the width direction of the adjustable dust shield box 4, and a middle fixing piece 2 is provided at the middle position of the adjustable dust shield box 4, and a fastener 3 is provided on the outside of the baffle panel 1 that passes through the middle fixing piece 2 and fixes the baffle panel 1 to the adjustable dust shield box 4.

[0027] See also Figure 3 A supporting portion 11 is provided on one side of the baffle panel 1, which is the "baffle tongue" described in the background technology. Positioning holes 12 are provided at both ends of the baffle panel 1, which are used to fix the baffle panel 1 to the lock body by screws. A center hole 14 is provided in the middle of the baffle panel 1 between the two positioning holes 12, which is used for the fastener 3 to pass through, so as to realize the fixation of the baffle panel 1 and the adjustment dust box 4. The baffle panel 1 is provided with two hollows on both sides of the center hole 14, and a bayonet 13 is provided in one of the hollows for sliding guidance of the baffle panel 1 and the adjustment dust box 4.

[0028] See also Figure 4 and Figure 5 A card slot 41 for placing the middle fixing plate 2 is opened in the middle position of the adjustment dust shield box 4, and a first waist-shaped groove 42 corresponding to the positioning hole 12 is opened at both ends of the adjustment dust shield box 4 to make room for the movement of the screw. A card head 43 is provided on one side of the adjustment dust shield box 4 to limit the sliding movement in the bayonet 13.

[0029] See also Figure 6A second waist-shaped groove 21 corresponding to the center hole 14 is provided on the middle fixing plate 2 to make way for the movement of the fastener 3.

[0030] See also Figure 7 and Figure 8 The fastener 3 includes a metal clip 31 and a bolt 32. The metal clip 31 is mounted outside the middle fixing plate 2 and is fixed to the baffle panel 1 by the bolt 32. The vertical cross-section of the metal clip 31 is in the shape of a teardrop. A first through hole 311 and a second through hole 312 are provided on both sides of the metal clip 31 for the bolt 32 to pass through. The aperture of the first through hole 311 is smaller than that of the second through hole 312.
