A manual obtuse-angle push-pull plate comprises a main frame, an installation space is formed inside the main frame, two push-pull plates 4 are symmetrically arranged in the middle of the installation space, the push-pull plates 4 move laterally along the length direction of the installation space, and two corner plates 5 are symmetrically arranged on the left and right sides of the installation space, the corner plates 5 are tilted backward from the outside to the inside, and the inner side of the corner plates 5 is located in front of the push-pull plate 4 to avoid the lateral movement of the push-pull plate 4.

[0026] The utility model provides a manual obtuse-angle push-pull plate. Compared with the prior art, the two push-pull plates 4 are symmetrically installed in the middle of the installation space of the main frame, and the two corner plates 5 are symmetrically installed on the left and right sides of the installation space of the main frame. The two push-pull plates 4 are both arranged longitudinally and can move laterally along the length direction of the installation space, and the corner plates 5 are arranged to tilt backward from the outside to the inside. In addition, the inner end of the corner plate 5 is located in front of the push-pull plate 4. When the push-pull plate 4 moves laterally to the outside, there is no need to adjust the corner plate 5. The push-pull plate 4 can be directly hidden behind the corner plate 5 through the inner end of the corner plate 5, which is more convenient to operate and avoids the problem of wasting class time due to adjusting the corner plate 5.

[0027] The main frame includes an upper frame 1 and a lower frame 2 arranged horizontally from top to bottom, and vertical frames 3 are respectively arranged on both sides of the upper frame 1 and the lower frame 2. The lengths of the upper frame 1 and the lower frame 2 are the same and both are greater than the lengths of the vertical frames 3, so that the main frame forms a rectangular frame, and the push-pull plate 4 and the corner plate 5 are both rectangular plates, and are installed in the installation space formed by the above-mentioned rectangular frame. Among them, the push-pull plate 4 moves laterally along the length direction of the upper frame 1 and the lower frame 2, and the outer side of the corner plate 5 is connected to the vertical frame 3 on the corresponding side.

[0028] See also Figure 3 The lower end surface of the upper frame 1 and the upper end surface of the lower frame 2 are respectively provided with slide rails 6 along the length direction, and the upper and lower ends of the push-pull plate 4 are both provided with sliders 7, which slide with the corresponding slide rails 6 to realize the lateral sliding of the push-pull plate 4.

[0029] There are multiple sliders 7 at the upper end of the push-pull plate 4, which are evenly spaced and evenly arranged; there are multiple sliders 7 at the lower end of the push-pull plate 4, which are evenly spaced and evenly arranged. Multiple sliders 7 slide in cooperation with the slide rail 6, which can improve the stability of the lateral sliding of the push-pull plate 4 and reduce shaking.

[0030] Specifically, the slider 7 includes a connecting section 71 and a bending section 72, and the connecting section 71 and the bending section 72 are integrally formed to form a hook structure. The connecting section 71 located at the upper end of the push-pull plate 4 has its lower end vertically connected to the upper end of the push-pull plate 4, and the bending section 72 is connected to the upper end of the connecting section 71, and the bending section 72 extends vertically downward after bending. Similarly, the connecting section 71 located at the lower end of the push-pull plate 4 has its upper end vertically connected to the lower end of the push-pull plate 4, and the bending section 72 is connected to the lower end of the connecting section 71, and the bending section 72 extends vertically upward after bending.

[0031] Correspondingly, the slide rail 6 includes a connecting plate 61 and a bending plate 62, and the connecting plate 61 and the bending plate 62 are integrally formed. The track connected to the lower end surface of the upper frame 1 has the upper end of the connecting plate 61 vertically connected to the lower end surface of the upper frame 1, and the bending plate 62 is bent and vertically extended upward, so that a slide groove 63 with an opening upward is formed between the connecting plate 61 and the bending plate 62, and the slide groove 63 extends along the length direction of the upper frame 1. The bending section 72 of the slider 7 at the upper end of the push-pull plate 4 is hooked in the slide groove 63, which can realize the sliding of the push-pull plate 4 along the length direction of the slide groove 63. Similarly, the track connected to the upper end surface of the lower frame 2 has its lower end of the connecting plate 61 vertically connected to the upper end surface of the lower frame 2, and the bending plate 62 is bent and vertically extended upward, so that a downwardly opening slide 63 is formed between the connecting plate 61 and the bending plate 62, and the slide 63 extends along the length direction of the lower frame 2. The bending section 72 of the slider 7 at the lower end of the push-pull plate 4 is hooked in the slide 63, and the push-pull plate 4 can be driven to slide along the length direction of the slide 63. Therefore, the push-pull plate 4 realizes overall stable lateral sliding through the cooperation of the upper slider 7 and the slide rail 6 and the cooperation of the lower slider 7 and the slide rail 6.

[0032] In addition, the upper and lower ends of the push-pull plate 4 are provided with mounting grooves 41 along their length direction, and a mounting plate 73 is provided at one end of the connecting section 71 away from the bending section 72. The mounting plate 73 is integrally formed with the connecting section 71, and relatively extending ribs are provided on both sides of the mouth of the mounting groove 41. The width of the mounting plate 73 is smaller than the width of the mounting groove 41, ensuring that the mounting plate 73 can smoothly enter the mounting groove 41. The width of the mounting plate 73 is greater than the gap between the two ribs, which can prevent the mounting plate 73 from longitudinally escaping from the mounting groove 41. Specifically, the mounting plate 73 is located in the mounting groove 41, and a connecting hole is provided at the bottom of the mounting plate 73. The mounting plate 73 is fixedly connected to the bottom of the mounting groove 41 by screws penetrating the connecting hole, thereby fixing the mounting plate 73 in the mounting groove 41.

[0033] See also Figure 5A connecting frame 51 is provided on the rear end face of the outer side of the corner plate 5, and a rotating body 52 is provided at the end of the connecting frame 51. A rotating groove 31 is provided on the front side of the inner wall of the vertical frame 3. The rotating body 52 is a cylindrical structure, and the rotating groove 31 is an adaptive semi-cylindrical cavity groove structure. The rotating body 52 is adapted to be installed in the rotating groove 31. The corner plate 5 can adjust its inclination angle through the rotational cooperation relationship between the rotating body 52 and the rotating groove 31, so that the inner end of the corner plate 5 can avoid the push-pull plate 4, so that the push-pull plate 4 can move smoothly laterally without adjusting the corner plate 5.

[0034] In addition, a plurality of positioning frames 8 are arranged at longitudinal intervals on the inner wall of the vertical frame 3. The positioning frames 8 are formed of a plurality of integrally formed folded plates. The plate body at one end of the positioning frame 8 is fixed to the inner wall of the vertical frame 3 by bolts, and the plate body at the other end of the positioning frame 8 is fixed to the rear end surface of the outer side of the corner plate 5 by bolts. The positioning frames 8 can position the corner plate 5 at a specific inclination angle, so that the corner plate 5 can remain stable without affecting the lateral movement of the push-pull plate 4.

[0035] Preferably, the outer side of the corner plate 5 extends to the outer side of the vertical frame 3 to cover the vertical frame 3. When people watch from the front, they cannot see the vertical frame 3, making the overall appearance more slender and beautiful.

[0036] See also Figure 1 A push-pull wrench 42 is respectively provided on one side of the front end surfaces of the two push-pull plates 4 that are close to each other, which is convenient for personnel to hold, so that the lateral movement of the push-pull plates 4 is more convenient.
