[0022] The present invention is further described in detail below in conjunction with the embodiments and drawings.

[0023] like Figures 1 to 5As shown, a firearm rear sight structure capable of adjusting the width of a gap comprises a rear sight seat 3, a bottom of the rear sight seat 3 is provided with an interface for connecting with a gun body, a square groove is provided above the rear sight seat 3, an adjusting rod 4 is provided between the two side walls of the square groove of the rear sight seat 3, a middle portion of the adjusting rod 4 is provided with a cross thread, a left rear sight 8 and a right rear sight 6 are provided in the square groove of the rear sight seat 3, a rear sight gap is formed between the left rear sight 8 and the right rear sight 6, a leaf spring 9 is provided between the bottom wall of the square groove of the rear sight seat 3 and the bottom of the left rear sight 8 and the right rear sight 6, the leaf spring 9 positions the left rear sight 8 and the right rear sight 6 circumferentially, the left rear sight 8 and the right rear sight 6 respectively cooperate with the cross thread on the adjusting rod 4 to form a screw nut mechanism, the threads on the left rear sight 8 and the right rear sight 6 have opposite rotation directions, and the adjusting rod 4 is used to drive the left rear sight 8 and the right rear sight 6 to move toward / away from each other.

[0024] Both ends of the adjusting rod 4 are clearance-matched with the rear sight seat 3. The right end of the adjusting rod 4 is provided with a head with an increased diameter, and an opening for matching with a screwdriver is provided on the end surface of the head of the adjusting rod 4. A countersink is provided on the right side wall of the rear sight seat 3. The step surface of the head of the adjusting rod 4 and the step surface of the countersink of the rear sight seat 3 are axially positioned. A head 1 and a head spring 2 are provided in the rear sight seat 3 corresponding to the head of the adjusting rod 4. The head 1 is perpendicular to the adjusting rod 4. A plurality of arc-shaped grooves are uniformly provided on the cylindrical surface of the head of the adjusting rod 4 along the circumferential direction. The head 1 is pushed into a groove under the action of the head spring 2, forming a circumferential positioning of the adjusting rod 4 and playing a role of stopping rotation. During the adjustment process, the adjusting rod 4 rotates, and the head 1 can slide out of the groove and enter the next groove for positioning.

[0025] A sight spring 7 is provided between the left sight 8 and the right sight 6. The sight spring 7 is sleeved on the adjustment rod 4. One end of the sight spring 7 contacts the left side wall of the right sight 6, and the other end contacts the right side wall of the left sight 8, so as to eliminate the transverse thread gap between the left sight 8, the right sight 6 and the adjustment rod 4. The adjustment rod spring 5 is on the right side of the right sight 6. One end of the adjustment rod spring 5 contacts the side wall of the right sight 6, and the other end contacts the side wall of the sight seat 3. The adjustment rod 4 passes through the adjustment rod spring 5. Under the action of the spring force of the adjustment rod spring 5, the end face of the right head of the adjustment rod 4 contacts the bottom face of the countersunk hole of the sight seat 3, and the transverse thread gap between the adjustment rod 4 and the right sight 6 can be eliminated. Under the action of the spring force of the leaf spring 9, the lower end faces of the left sight 8 and the right sight 6 always contact the leaf spring 9, so as to eliminate the longitudinal thread gap between the adjustment rod 4 and the right sight 6.

[0026] The thread of the adjustment rod 4 is a cross thread, which can engage with a left-handed or right-handed thread. The left sight 8 and the right sight 6 have a left-handed threaded through hole or a right-handed threaded through hole respectively. The threads of the left sight 8 and the right sight 6 are in opposite directions, and are matched with the cross thread of the adjustment rod 4 and installed on the adjustment rod 4. When the adjustment rod 4 is rotated, the left sight 8 and the right sight 6 will be driven to move in different directions respectively, so that the width of the sight gap can be adjusted.
