[0002] In the building door and window industry, as an important hardware fitting, the sliding brace is widely used in the opening and closing operations of various doors and windows. The traditional sliding brace design usually adopts a relatively simple structure, mainly including basic components such as a bottom rail, a sliding block, a stress arm, a supporting arm, and a guiding arm, and realizes the opening and closing of the door and window through the sliding of the sliding block.
[0003] In the traditional sliding brace, the bottom rail is horizontally installed on the door and window, and usually a chute is provided on the bottom rail, and the sliding block is slidably connected to the chute. Usually, a stainless steel rivet and a plastic damping member are also provided in the chute. The stainless steel rivet is fixed in the chute, and the plastic damping member moves together with the sliding block. When the plastic damping member abuts against the stainless steel rivet, the sliding brace is opened to the maximum angle. However, under extreme weather conditions, such as strong wind or typhoon weather, the strength of the plastic damping member is insufficient to cope with the strong impact under extreme weather conditions; secondly, the contact surface between the plastic damping and the stainless steel rivet is too small, the stainless steel rivet is easy to damage the plastic damping, and the stainless steel rivet is easy to deform, so the anti-destruction performance of the sliding brace is poor, which not only affects the normal use of the door and window, but also may bring potential safety hazards. In addition, the traditional sliding brace is made of stainless steel, and a stainless steel connecting member is provided in the chute to connect the slider and the guiding arm, and a plastic gasket is sleeved outside the stainless steel connecting member to reduce the wear between the chute and the stainless steel connecting member. However, the strength of the plastic gasket is insufficient, the indirect contact area between the stainless steel connecting member and the chute is too small, and the plastic gasket is easy to get stuck in the chute, resulting in the stainless steel connecting member and the slider being separated from the chute, there is a potential safety hazard.
[0004] The above defects need to be solved urgently. Content of the Utility Model
[0005] In order to solve the problems that the strength of the plastic damping member of the existing sliding brace is insufficient and the contact surface between the plastic damping and the stainless steel rivet is too small, resulting in poor anti-destruction performance of the sliding brace, the utility model provides a sliding brace with improved anti-destruction performance.
[0006] The technical solution of the utility model is as follows:

[0009] The blocking block is arranged on the side of the force-bearing arm close to the sliding block, and the blocking block is connected to the fixed arm by a stainless steel rivet. A plastic damping member is arranged on the side of the sliding block away from the blocking block.
[0010] The utility model according to the above solution further includes an auxiliary arm. One end of the auxiliary arm is hinged to the supporting arm, and the other end of the auxiliary arm is hinged to the blocking block.
[0011] In the utility model according to the above solution, the blocking block protrudes outwards to form a first limiting portion, and a second limiting portion is arranged on the fixed arm.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0028] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.
[0029] As Figure 1 shown, the present utility model provides a sliding support for improving anti-destruction performance, which includes a fixed arm 1, a stress arm 2, a supporting arm 3, a guiding arm 4, and an auxiliary arm 5. The fixed arm 1 is installed on the wall, ensuring the stability and reliability of the sliding support. One side of the fixed arm 1 is bent upward to form a chute 11, on which a sliding block 6 and a blocking block 7 are arranged. One end of the stress arm 2 is hinged to the fixed arm 1, and the other end of the stress arm 2 is hinged to one end of the supporting arm 3. The doors and windows are installed on the supporting arm 3, enabling the supporting arm 3 to perform corresponding actions as the stress arm 2 rotates, thereby realizing the supporting function for the doors and windows. The other end of the supporting arm 3 is hinged to one end of the guiding arm 4, the other end of the guiding arm 4 is hinged to the sliding block 6, and the sliding block 6 is slidably connected to the chute 11. The guiding arm 4 will guide the sliding block 6 to slide in the chute 11, thereby realizing the opening and closing of the doors and windows. One end of the auxiliary arm 5 is hinged to the supporting arm 3, and the other end of the auxiliary arm 5 is hinged to the blocking block 7. The design of the auxiliary arm 5 further enhances the stability and load-bearing capacity of the sliding support, making the sliding support more stable and reliable when bearing the weight of the doors and windows.
[0030] In the existing sliding support, the stress arm 2 is slidably connected to the fixed arm 1, and the stress arm 2, the auxiliary arm 5, the sliding block 6 and the connecting piece 100 are integrated. It is difficult to ensure the same height of each component, and it is difficult to ensure the same space for the parts that need to slide in the chute 11. In this embodiment, the stress arm 2 is hinged to the fixed arm 1, and the stress arm 2 does not need to slide together with the sliding block 6 and the connecting piece 100, making it easy to ensure the same height of the stress arm 2, that is, it is easy to ensure the same space for a part in the chute 11. In addition, in each opening and closing of the sliding support, the stress arm 2 needs to rotate and does not need to slide, which can reduce the reserved gap in the chute 11 and reduce the wear and deformation of the sliding support.
[0031] As Figure 1 、 Figure 2 shown, in this embodiment, the chute 11 is arranged along the length direction of the fixed arm 1, ensuring that the sliding block 6 can slide smoothly and smoothly along the length direction of the fixed arm 1. The existence of the chute 11 not only provides a clear moving path for the sliding block 6, but also increases the stability and reliability of the sliding.
[0032] As Figure 1 、 Figure 2 、 Figure 5As shown in the figure, in this embodiment, the blocking block 7 is arranged on the side of the force-bearing arm 2 close to the sliding block 6, and the blocking block 7 is connected to the fixed arm 1 by a stainless-steel rivet 8, that is, the position of the blocking block 7 on the fixed arm 1 is fixed. A plastic damping member 9 is arranged on the side of the sliding block 6 away from the blocking block 7. Compared with the traditional slide support, the stainless-steel rivet 8 of the present utility model passes through the blocking block 7 and is connected to the force-bearing arm 2, that is, the plastic damping member 9 of the present utility model does not contact the stainless-steel rivet 8. When the slide support is opened to the maximum angle, the blocking block 7 and the sliding block 6 are in mutual abutment for limiting, and the blocking block 7 and the sliding block 6 are in surface-to-surface contact, increasing the contact area between the blocking block 7 and the sliding block 6, making the blocking block 7 and the sliding block 6 more stable when bearing external forces, not easily deformed, capable of improving the anti-destruction performance of the slide support, ensuring the normal use of doors and windows, and reducing potential safety hazards.
[0033] As Figure 1 , Figure 4 , Figure 5 shown, in this embodiment, the plastic damping member 9 is snap-connected to the sliding block 6. The main function of the plastic damping member 9 is to provide resistance to adjust the moving speed of the sliding block 6 in the sliding groove 11, so as to achieve smooth and safe sliding. In addition, the snap-fastening connection between the plastic damping member 9 and the sliding block 6 ensures the close fit and stability between the two, enabling the plastic damping member 9 to move along with the sliding block 6, which is not only convenient for installation and disassembly, but also can maintain the effectiveness of the plastic damping member 9 during use, not easily falling off or shifting. Additionally, a damping installation position is provided on the sliding block 6, and at least a part of the plastic damping member 9 is arranged on the damping installation position to ensure that the plastic damping member 9 can be stably installed on the sliding block 6 and move along with the sliding block 6.
[0034] As Figure 1 , Figure 4 , Figure 5 shown, in this embodiment, the plastic damping member 9 includes a damping housing 91. A damping adjustment groove 92 is provided on the damping housing 91, and the width of the damping adjustment groove 92 gradually decreases from one side of the damping housing 91 to the other side. The damping adjustment member 93 is connected to the damping adjustment groove 92. By adjusting the position of the damping adjustment member 93 in the damping adjustment groove 92, the height of the damping housing 91 is adjusted, and further the damping magnitude of the plastic damping member 9 is adjusted. When the damping adjustment member 93 is moved from the end with a larger width of the damping adjustment groove 92 to the end with a smaller width of the damping adjustment groove 92, the height of the damping housing 91 becomes larger, thereby making the sliding resistance of the sliding block 6 larger. On the contrary, the height of the damping housing 91 becomes smaller, thereby making the sliding resistance of the sliding block 6 smaller.
[0035] As Figure 1 , Figure 2 , Figure 5As shown, in this embodiment, the blocking block 7 protrudes outward to form a first limiting portion 71. A second limiting portion 12 is provided on the fixed arm 1. The second limiting portion 12 extends into the sliding groove 11 and abuts against the upper end surface of the first limiting portion 71. During the operation of the sliding support, whether it is opened or closed, the second limiting portion 12 will closely fit with the first limiting portion 71 to prevent the blocking block 7 from disengaging from the sliding groove 11 and ensure the stable position of the blocking block 7. In addition, at least a part of the blocking block 7 is arranged in the sliding groove 11, and the auxiliary arm 5 is hinged to the part of the blocking block 7 exposed from the sliding groove 11, which can reduce the width of the sliding groove 11 and reduce the friction and wear of the auxiliary arm 5 in the sliding groove 11.
[0036] As Figure 1 , Figure 3 , Figure 5 As shown, in this embodiment, a connecting member 100 is provided on the top of the sliding block 6. The connecting member 100 is arranged in the sliding groove 11. A rivet passes through the sliding block 6 and is hinged to the connecting member 100, and the second limiting portion 12 of the blocking block 7 abuts against the upper end surface of the connecting member 100. When the sliding block 6 moves in the sliding groove 11, the second limiting portion 12 will always be in contact with the upper end surface of the connecting member 100 to ensure that the sliding block 6 will not move excessively or disengage from the sliding groove 11, which not only improves the stability and safety of the sliding support, but also makes the sliding block 6 move more smoothly and stably during the movement. In addition, at least a part of the sliding block 6 is arranged in the sliding groove 11, and the guiding arm 4 is hinged to the part of the sliding block 6 exposed from the sliding groove 11. Then, the inside of the sliding groove 11 does not need to provide additional space for the guiding arm 4, so that the width of the sliding groove 11 can be correspondingly reduced, thereby reducing the use of materials and the occupation of space, reducing the friction and wear of the guiding arm 4 in the sliding groove 11, and improving the stability and reliability of the entire sliding support.
[0037] In this embodiment, it is possible to design the connecting member 100 not to contact the obstructing member, or to design the connecting member 100 to contact the obstructing member to improve the assembly stability of the sliding block 6 and the obstructing block 7. During actual design, the connection relationship between the connecting member 100 and the obstructing member can be designed according to actual needs. In addition, the material of the connecting member 100 is copper, and the material of the obstructing block 7 is zinc alloy. The obstructing block 7 and the sliding block 6 have higher strength than the plastic damping member 9, enabling the slide support to withstand strong impacts under extreme weather conditions. Of course, during actual design, the materials of the connecting member 100 and the obstructing block 7 can be designed according to actual circumstances. Additionally, the strength of the obstructing block 7 is close to that of the stainless steel rivet 8, so the obstructing block 7 is not easily deformed after being connected to the stainless steel rivet 8, improving the connection stability between the two. At the same time, compared with traditional slide supports, the connecting member 100 of the present utility model does not require a plastic gasket to be sleeved on its outer side, which increases the thickness of the connecting member 100, increases the contact area between the connecting member 100 and the sliding groove 11, and the wear resistance of the copper material connecting member 100 is high, and the copper material connecting member 100 has higher strength than the plastic gasket, improving the assembly stability of the connecting member 100 and the sliding groove 11, making it difficult for the connecting member 100 and the sliding block 6 to disengage from the sliding groove 11, and reducing potential safety hazards.
[0038] As Figure 1 , Figure 5 shown, in this embodiment, a clamping block 200 for connecting with the door or window is provided at the hinge joint of the force arm 2 and the supporting arm 3. A supporting convex block 2001 is provided at the bottom of the side of the clamping block 200 close to the door or window, and the supporting convex block 2001 abuts against the bottom of the door or window, shifting the center of gravity of the door or window from the center to the corner, enabling the slide support to better disperse and bear the weight of the door or window, not only improving the load-bearing capacity of the slide support, but also effectively reducing the occurrence of the phenomenon of the door or window sagging, providing a safer and more reliable use experience for the occupants.
[0039] As Figure 1 , Figure 5As shown, in this embodiment, the side of the clamping block 200 is provided with a plurality of first threaded holes, and the side top screw 2002 fixes the clamping block 200 to the door and window through the first threaded hole, ensuring that the door and window can remain stable and not easily shake or shift when subjected to external force. In addition, the clamping block 200 is provided with a second threaded hole, and the top top screw 2003 is threadedly connected to the clamping block 200 through the second threaded hole. The supporting arm 3 is provided with an adjustment rod, and the clamping block 200 is sleeved on the adjustment rod through the second threaded hole, and the top top screw 2003 abuts against the adjustment rod. The adjusting rod is arranged on the stress point, the clamping block 200 is sleeved on the adjusting rod through the second threaded hole, the top top screw 2003 abuts against the adjusting rod, and the gap between the door and window and the sliding support is adjusted. The top top screw 2003 is adjusted downward along the second threaded hole, and the clamping block 200 is subjected to an upward thrust, and the clamping block 200 moves upward, and the gap between the door and window and the sliding support becomes larger, so that the door and window will not press the stress arm 2 of the sliding support, and the sliding support cannot be opened or closed normally. In addition, a plastic ring is provided at the bottom of the top top screw 2003, and the top top screw 2003 abuts against the adjusting rod through the plastic ring, which plays a buffering role on the top top screw 2003, and prevents the adjustment of the top top screw 2003 from causing damage to the adjusting rod.
