DETAILED DESCRIPTION

[0024] The present invention is described in detail below with reference to the accompanying drawings and embodiments.

[0025] This embodiment provides a telescopic positioning clamping mechanism, which has the advantages of small size, easy operation, reliable positioning and convenient module installation. It can be flexibly pulled out and positioned, and can be applied to equipment with strict space requirements.

[0026] like Figure 1-3 As shown, the positioning and clamping mechanism includes: a module bracket 1, an outer cover 2, a support 3, a two-section guide rail 4 and a wedge-shaped guide rail assembly 5; wherein, the two-section guide rail 4 includes: a two-section guide rail inner guide rail 6, a retaining spring I 7, a retaining spring II 8 and a two-section guide rail outer guide rail 9; the wedge-shaped guide rail assembly 5 includes: a wedge-shaped guide rail and a wedge-shaped guide rail mounting seat 12; the wedge-shaped guide rail includes: a wedge-shaped guide rail front slider 11, a wedge-shaped guide rail fixing block 13 and a wedge-shaped guide rail rear slider 14.

[0027] The connection relationship of the positioning and clamping mechanism is as follows: the outer cover 2 is fixedly mounted on one longitudinal end of the module bracket 1 by means of buckles and screws, and the lateral sides of the module bracket 1 are mounted on two two-section guide rails 4 embedded in the bottom thereof, and each two-section guide rail 4 is retractable relative to the module bracket 1, and can be locked in state after being retracted to a set position; Figure 4 As shown, two two-section guide rails 4 are respectively mounted on two wedge-shaped guide rail assemblies 5, and the two wedge-shaped guide rail assemblies 5 are respectively embedded and pressed and positioned in the corresponding supports 3, and the entire positioning clamping mechanism is fixed on the installation plane through the two supports 3; the shape of the outer cover 2 can be aligned with the outer shell of the equipment stand;

[0028] The support 3 and the two guide rails 4 are compactly embedded in the lateral sides of the module bracket 1. The bottom surface of the support 3 is slightly lower than the bottom of the module bracket 1 and is fixed on the installation plane, which greatly reduces the installation space of the positioning clamping mechanism and reserves the largest space for the installation of the module.

[0029] Furthermore, the two two-section guide rail inner guide rails 6 are respectively embedded and fixed on the lateral sides of the module bracket 1, and the two two-section guide rail outer guide rails 9 are respectively fixedly installed on the corresponding wedge-shaped guide rail components 5. The two-section guide rail inner guide rail 6 and the two-section guide rail outer guide rail 9 on the same side are slidably matched, and a sliding cavity is formed between the two. A retaining spring I7 and a retaining spring II8 are respectively arranged at the longitudinal ends of the sliding cavity, so that the end where the outer cover 2 is located is the proximal end of the positioning and clamping mechanism, and the other end is the distal end; the retaining spring I7 is located at the proximal end, the retaining spring II8 is located at the distal end, and one end of the retaining spring I7 and the retaining spring II8 are both fixed on the two-section guide rail inner guide rail 6, and the other ends are both in contact with the two-section guide rail outer guide rail in a free state. 9; a positioning block is provided on the proximal upper surface of the two-section guide rail outer guide rail 9. When the two-section guide rail outer guide rail 9 is completely retracted relative to the two-section guide rail inner guide rail 6, one end of the retaining spring Ⅰ7 abuts against the two-section guide rail outer guide rail 9 and is clamped on the positioning block, so that the retracted state between the two-section guide rail inner guide rail 6 and the two-section guide rail outer guide rail 9 is locked; when the two-section guide rail outer guide rail 9 is completely unfolded relative to the two-section guide rail inner guide rail 6, one end of the retaining spring Ⅱ8 abuts against the two-section guide rail outer guide rail 9 and is clamped on the positioning block, so that the unfolded state between the two-section guide rail inner guide rail 6 and the two-section guide rail outer guide rail 9 is locked. After the unfolded state is locked, the module can be installed on the module bracket 1 and the corresponding operation can be performed;

[0030] Furthermore, when the inner guide rail 6 of the two-section guide rail and the outer guide rail 9 of the two-section guide rail are in a retracted state, double locking can be performed by means of a non-loose nail assembled on the second-section guide rail 4, which is conducive to reinforcing the retracted state between the inner guide rail 6 of the two-section guide rail and the outer guide rail 9 of the two-section guide rail;

[0031] Furthermore, the switching between the two matching states (the folded state and the unfolded state) between the two-section guide rail inner guide rail 6 and the two-section guide rail outer guide rail 9 can be unlocked from the current matching state by manually squeezing the retaining spring I7 or the retaining spring II8, so that the two-section guide rail outer guide rail 9 can slide relative to the two-section guide rail inner guide rail 6, thereby switching the two-section guide rail inner guide rail 6 and the two-section guide rail outer guide rail 9 to another matching state;

[0032] Furthermore, if Figure 5As shown, each wedge-shaped guide rail is formed by a wedge-shaped guide rail screw 10 that passes through the wedge-shaped guide rail front slider 11, the wedge-shaped guide rail fixing block 13 and the wedge-shaped guide rail rear slider 14 in sequence and then screwed together; the wedge-shaped guide rail mounting seat 12 is an inverted T-shaped structure, and the two wedge-shaped guide rails are respectively located on the horizontal section of the wedge-shaped guide rail mounting seat 12, and are arranged on both sides of the vertical section, and are riveted on the vertical section to form a wedge-shaped guide rail assembly 5; the wedge-shaped guide rail front slider 11 and the wedge-shaped guide rail rear slider 14 are respectively matched with the inclined surfaces of the wedge-shaped guide rail fixing block 13, and the inclined surfaces are inclined in opposite directions. When the wedge-shaped guide rail screw 10 is tightened, the wedge-shaped guide rail front slider 11 and the wedge-shaped guide rail rear slider 14 are lifted up by the inclined surfaces on both sides of the wedge-shaped guide rail fixing block 13, thereby being pressed against the upper end of the support 3; at the same time, the wedge-shaped guide rail fixing block 13 and the wedge-shaped guide rail mounting seat 12 are pressed against the lower end of the support 3;

[0033] Furthermore, waist-shaped holes are respectively provided in the front slider 11 of the wedge-shaped guide rail and the fixing block 13 of the wedge-shaped guide rail, and a threaded hole is provided in the rear slider 14 of the wedge-shaped guide rail. When the wedge-shaped guide rail screw 10 is rotated, the clamping force of the wedge-shaped guide rail assembly 5 can be adjusted bidirectionally along both ends of the longitudinal direction, so that the longitudinal locking and force transmission of the positioning and clamping mechanism can be reliably achieved, and the overturning phenomenon of the positioning and clamping mechanism during the operation can be effectively prevented. Compared with the conventional screw installation, the stability of the module operation during the pulling and pulling can be more reliably guaranteed.

[0034] In summary, the above are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
