Detailed Description

The following further explains the specific embodiments of the present invention with reference to the drawings, and clearly and completely describes the technical solutions in the embodiments of the present invention.

The first embodiment is as follows:

a turning bracket comprises a connecting seat 1 for fixing the bracket, a turning structure 2 for connecting the connecting seat 1 and a clamping part 3 for clamping a sighting telescope; the overturning structure 2 comprises an overturning shaft 21, a first spring 26, a second spring 22 and a support frame 23, wherein the first spring 26, the second spring 22 and the support frame 23 are sleeved on the overturning shaft 21, a pin hole 241 is formed in the support frame 23, and the overturning of the clamping part 3 is limited by the fact that a stop block 27 enters and exits the pin hole 241; the clamping part 3 is fixed on the support frame 23 through the fixing bolt 4 and rotates around the overturning shaft 21 along with the support frame 23. On will overturn the support through connecting seat 1 and be fixed in gun, 3 centre gripping sighting telescope of clamping part rotate around trip shaft 21 along with support frame 23 to realize the upset of sighting telescope, after the sighting telescope position control is good, make it insert pinhole 241 through rotatory dog 27 and make the trip shaft 21 can not overturn, thereby fixed sighting telescope.

In order to better fix the sighting telescope after the position is adjusted and prevent the sighting telescope from moving in the using process, the support frame 23 is square, two opposite sides of the support frame 23 extend to one side to form the turnover connecting blocks 24, and the support frame 23 is sleeved on the turnover shaft 21 through holes in the two turnover connecting blocks 24. The second spring 22 is disposed inside two flip connector blocks 24.

Upset connecting block 24 is the trapezium structure to block on connecting seat 1 through two trapezoidal base angles, prevent that trip shaft 21 from rotatory. The second spring 22 and two turning connecting blocks 24 of the supporting frame 23 are clamped on the connecting seat 1 together, so that the fixing is firmer.

Two ends of one side of the connecting seat 1 are upwards formed with two turning support rods, namely a first turning support rod 12 and a second turning support rod 11, and the two turning support rods are sleeved on the turning shaft 21.

One end of the turning shaft 21 is fixed with a handle 25, the other end is fixed with a block 27, and the block 27 is in a column shape with an oval cross section. The handle 25 and the first flip support bar 12 are connected to both ends of the first spring 26. The stopper 27 passes through the second inversion support bar 11, and when the first spring 26 is compressed, the inversion shaft 21 is moved such that the stopper 27 passes through and moves inside the second inversion support bar 11.

One side that support frame 23 and clamping part 3 are connected is provided with rectangle bayonet 231, and two ends of second spring 22 outwards overturn for the straight line, and one end card is in connecting seat 1 below, and the other end card is in bayonet 231.

In order to insert the stopper 27 into the pin hole 241 to restrict the turning when the turning structure 2 is fixed, the pin hole 241 is provided on one surface of the turning connecting block 24 adjacent to the stopper 27, the pin hole 241 has the same cross section as the two stoppers 27 perpendicular to each other, and the center of the pin hole 241 coincides with the center of the through hole of the turning connecting block 24.

When the sighting telescope needs to be adjusted, the handle 25 is pressed to compress the first spring 26, the stop block 27 is moved out of the pin hole 241, and at the moment, the support frame 23 can be arbitrarily turned around the turning shaft 21 to adjust the position of the sighting telescope. After the sighting telescope moves to a required position, if the sighting telescope is turned over by 90 degrees, the handle is loosened, the turnover shaft 21 reversely moves under the elastic action of the first spring 26, the stop block 27 moves and is inserted into the pin hole 241, the turnover shaft 21 stops rotating, and the sighting telescope is fixed in position. The second spring 22 and the turning connecting block 24 assist in fixing the turning structure 2, so that the fixing is more stable.

In a preferred embodiment, in order to fix the supporting frame 23 and the holding portion 3 more firmly, and the position of the sighting telescope will not change when the sighting telescope is adjusted to work, a groove 232 is provided on one side of the supporting frame 23 facing the holding portion 3, a protrusion 31 matching with the groove 232 is provided on the holding portion 3, and a matching tooth-like structure 233 is provided on the position of the groove 232 corresponding to the protrusion 31. The groove 232, the protrusion 31 and the tooth-shaped structure 233 are combined with each other, so that the relative movement between the supporting frame 23 and the clamping part 3 is prevented, and the fixation is firmer.

Example two:

unlike the first embodiment, the support frame 23 is further provided with a rectangular through hole 234 extending in the longitudinal direction, so that the holder 3 moves up and down along the rectangular through hole 234. The fixing bolt 4 is fixed to the holder 3 through the rectangular through hole 234.

When the height of the sighting telescope needs to be adjusted, the fixing bolt 4 is unscrewed, the fixing bolt 4 moves along the rectangular through hole 234, the clamping part 3 is driven to move up and down, and when the height is adjusted to be required, the fixing bolt 4 is screwed down, and the clamping part 3 is fixed.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those skilled in the art; the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not substantially depart from the scope of the embodiments of the present invention, and are intended to be covered by the claims and the specification.
