[0044] In order to make the purpose, technical scheme and advantages of the utility model more clearly understood, the utility model will be further described in detail below in combination with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the utility model and are not used to limit the utility model.
[0045] As Figure 1As shown, it is the structural schematic view of the balcony guardrail sliding support provided by the embodiment of the utility model, the balcony guardrail sliding support is used for installing the window sash to the balcony guardrail, and the opening and positioning of the window sash are realized. The balcony guardrail sliding support of the embodiment includes slide rail 21, support arm 11, first cantilever 12, second cantilever 13, third cantilever 14 and sliding block assembly 30, wherein the slide rail 21 has sliding groove, and the sliding block assembly 30 is arranged in the sliding groove; the first end of the first cantilever 12 and the second cantilever 13 are respectively hinged with the support arm 11, the tail end of the second cantilever 13 and the third cantilever 14 are respectively hinged with the slide rail 21, the tail end of the first cantilever 12 is hinged with the sliding block assembly 30, and the first end of the third cantilever 14 is hinged on the middle part of the first cantilever 12 in the length direction. The support arm 11, the first cantilever 12, the second cantilever 13 and the third cantilever 14 and the connecting structure thereof can adopt the conventional structure in the field, and will not be repeated here.
[0046] The sliding block assembly 30 has a clamping block, and the slide rail 21 has a plurality of clamping grooves 215 matched with the clamping block, the sliding block assembly 30 is prevented from closing the window sash by embedding the clamping block into the clamping groove 215, and at least one clamping groove 215 is located at the position of the tail end of the first cantilever 12 when the support arm 11 is perpendicular to the slide rail 21, so that the clamping block on the sliding block assembly 30 can be embedded into the clamping groove 215 when the sliding block assembly 30 is slid to the clamping groove 215 by the first cantilever 12, thereby preventing the window sash from closing and realizing the 90° opening and positioning of the window sash.
[0047] The balcony guardrail sliding support is matched by the clamping block on the sliding block assembly 30 and the clamping groove on the slide rail 21 corresponding to the position of the tail end of the first cantilever when the support arm is perpendicular to the slide rail, so that the window sash installed to the balcony guardrail can be opened to 90°, thereby facilitating the drying of clothes.
[0048] Combining Figure 2 , Figure 3 As shown, in an embodiment of the utility model, the slide rail 21 is processed from a metal material with high strength and in a strip shape. The slide rail 21 specifically includes bottom plate 211, two side plates 212 and two folded edges 213, wherein the two side plates 212 are connected to the width direction of the bottom plate 211 (such as the left-right direction in the drawing), and the two folded edges 213 are connected to the length direction of the bottom plate 211 (such as the up-down direction in the drawing). Figure 3The two edges (in the direction indicated by arrow X) are connected to the tops of the two side plates 212 respectively, and the two edges 213, the two side plates 212 and the bottom plate 211 are connected in a C-shape (i.e., there is a gap between the two edges 213), and a sliding groove 214 is formed between the two edges 213, the two side plates 212 and the bottom plate 211 along the length direction of the slide rail 21. A slot 215 is formed on the edge 213 and is connected to the sliding groove 214. In addition, multiple slots 215 distributed along the length direction of the slide rail 21 can be formed on the edge 213. In particular, each edge 213 has multiple slots 215, and the slots 215 on the two edges 213 are aligned in the width direction of the slide rail 21.
[0049] In practical implementation, the aforementioned slide rail 21 can adopt a two-section structure, for example, consisting of a main slide rail and a fixing rod connected together. The sliding groove 214 is located on the main slide rail, and the fixing rod has a wrap-around corner 22. The main slide rail adopts an integral structure, meaning the side plate 212 is formed by vertically bending the outer edge of the base plate 211, and the folded edge 213 is formed by vertically bending the outer edge of the side plate 212. Similar to existing sliding supports, when the aforementioned balcony railing sliding support is assembled to the window frame, the slide rail 21 is fixed to the horizontal profile of the base plate of the window frame using screws or the like.
[0050] In one embodiment of this utility model, the slider assembly 30 includes a limiting block 31 and an elastic element 34. The limiting block 31 can be made of materials such as metal or hard plastic. Figure 4 , Figure 6 As shown, the locking block 312 protrudes from the two sides of the main body 311 of the limiting block 31 in the width direction, and the width of the main body 311 of the limiting block 31 is less than or equal to the gap between the two folded edges 213. The distance between the outer edges of the two locking blocks 312 is less than the distance between the inner sides of the two side plates 212 on the slide rail 21. The size and position of each locking block 312 correspond to the locking groove 215 on the slide rail 21.
[0051] When the limiting block 31 is installed into the slide rail 21, the elastic member 34 is installed between the limiting block 31 and the bottom plate 211 of the slide rail 21, that is, the elastic member 34 pushes the corresponding part of the limiting block 31 away from the bottom plate 211, and when the limiting block 31 slides towards the first direction and the clamping block 312 passes through the clamping groove 215, the elastic member 34 pushes the limiting block 31 to make the clamping block 312 embedded into the clamping groove 215. Specifically, a blind hole can be opened on the bottom plate of the limiting block 31, the elastic member 34 includes a spring 341 installed into the blind hole and a steel ball 342, and the steel ball 342 is pushed out of the lower surface of the limiting block 31 by the spring 341, thereby applying a force away from the bottom plate 211 to the limiting block 31. It can be understood by those skilled in the art that the embedding of the limiting block 31 into the sliding groove 214 means that the clamping blocks 312 on both sides of the limiting block 31 are respectively embedded between the two folded edges 213 and the bottom plate 211, and the main part 311 of the limiting block 31 is located between the gaps of the two folded edges 213.
[0052] In an embodiment of the present application, the sliding block assembly 30 further comprises a connecting block 32 and a fixing plate 33, which are also made of metal, hard plastic or other materials. As shown in Figure 4 、 Figure 6 The limiting block 31 also comprises a relief notch 313 extending from the lower surface of the main part 311 to the front end face, that is, the front end of the main part 311 of the limiting block 31 is vacant.
[0053] The fixing plate 33 is also embedded into the sliding groove 214 and can slide along the length direction of the sliding groove 214, and the relief notch 313 on the limiting block 31 faces the fixing plate 33. It can be understood by those skilled in the art that the embedding of the fixing plate 33 into the sliding groove 214 means that the two side edges of the fixing plate 33 are respectively embedded between the two folded edges 213 and the bottom plate 211. The connecting block 32 is stacked on the fixing plate 33, one end of the connecting block 32 is movably connected with the limiting block 31, and at least a part of the fixing plate 33 protrudes from the main part of the connecting block 32 towards the limiting block 31. The movably connecting of the connecting block 32 with the limiting block 31 means that the connecting block 32 can move within a certain range relative to the limiting block 31 in the length direction of the slide rail 21, that is, the connecting block 32 can move alone along the length direction of the slide rail 21 (the limiting block 31 remains stationary) while driving the limiting block 31 to move along the length direction of the slide rail 21.
[0054] As Figure 2As shown, the tail end of the first cantilever 12, the connecting block 32 and the fixed plate 33 are connected together through the pin shaft 35, and the sliding block assembly 30 is driven by the first cantilever 12 to slide in the sliding groove 214, and the tail end of the first cantilever 12 can rotate around the pin shaft 35. Specifically, the tail end of the first cantilever 12, the connecting block 32 and the fixed plate 33 have through holes respectively, and the pin shaft 35 passes through the through holes of the tail end of the first cantilever 12, the connecting block 32 and the fixed plate 33 to assemble them together, and the pin shaft 35 can be a rivet or the like, and in order to ensure the stability of the connection, a gasket 36 can also be arranged between the connecting block 32 and the tail end of the first cantilever 12.
[0055] When the first cantilever 12 drives the sliding block assembly 30 to slide towards the first direction (i.e. the opening direction of the window sash), the clamping block 312 of the limiting block 31 passes through the clamping groove 215, the elastic member 34 pushes the limiting block 31 to make the clamping block 312 embedded into the clamping groove 215, and when the clamping block 312 is embedded into the clamping groove 215, the limiting block 31 can only slide towards the first direction, and cannot slide against the first direction (i.e. the closing direction of the window sash), so as to realize the angle limiting of the opening window. When the first cantilever 12 drives the sliding block assembly 30 to slide against the first direction (the clamping block 312 is not embedded into the clamping groove 215), the fixed plate 33 is inserted into the avoiding notch 313 of the limiting block 31 and prevents the clamping block 312 of the limiting block 31 from being embedded into the clamping groove 215, so as to facilitate the closing operation of the window. Specifically, in order to facilitate the embedding of the clamping block 312 into the clamping groove 215, the elastic member 34 can be located between the two clamping blocks 312.
[0056] As shown in the drawings, Figure 4 In an embodiment of the utility model, the above-mentioned clamping block 312 includes a first inclined surface 3122 facing the first direction and a retreat stop surface 3121 (for example, the retreat stop surface 3121 can specifically adopt a vertical surface) facing against the first direction, when the clamping block 312 is embedded into the clamping groove 215, the retreat stop surface 3121 prevents the limiting block 31 from moving against the first direction, and further prevents the sliding block assembly 30 and the tail end of the first cantilever 12 from moving against the first direction, that is, the window cannot be closed at this time. And when the clamping block 312 is embedded into the clamping groove 215, the first inclined surface 3122 cooperates with the folded edge 213 of the sliding rail 21, the limiting block 31 can overcome the elastic force of the elastic member 34 to make the clamping block 312 disengage from the clamping groove 215 and re-embed into the sliding groove 214, that is, the limiting block 31 can still move towards the first direction, and further makes the opening angle of the window sash increase. Through the first inclined surface 3122 and the retreat stop surface 3121 on the clamping block 312, the clamping block 312 can only slide in one direction after being embedded into the clamping groove 215.
[0057] As shown in the drawings, Figure 8As shown, in one embodiment of this utility model, in order to better prevent backward movement, a second inclined surface 316 is provided between the aforementioned clearance notch 313 and the lower surface of the limiting block 31. That is, the clearance notch 313 and the lower surface of the limiting block 31 are connected through the second inclined surface 316. In this way, when the elastic member 34 pushes the locking block 312 upward and embeds it into the locking groove 215, the limiting block 31 can be twisted, so that the second inclined surface 316 abuts against the bottom plate 211 of the slide rail 21, and the front end of the top surface of the clearance notch 313 also abuts against the bottom plate 211 of the slide rail 21. At this time, the fixing plate 33 cannot be inserted into the clearance notch 313, so the limiting block 31 cannot move away from the first direction.
[0058] To prevent the limiting block 31 from dislodging from the sliding groove 214 of the slide rail 21 when the locking block 312 is inserted into the locking groove 215, in one embodiment of this utility model, the two side walls of the main body portion 311 of the limiting block 31 in the width direction each have a protrusion 318. The protrusion 318 is located on the front side of the locking block 312 (i.e., the side facing the fixing plate 33), and when the locking block 312 is inserted into the locking groove 215, the protrusion 318 remains embedded in the sliding groove 214. That is, the two protrusions 318 are respectively located between the folded edge 213 of the slide rail 21 and the base plate 211. Specifically, to facilitate the torsion of the limiting block 31, the protrusion 318 can be cylindrical.
[0059] Combination Figure 4 , Figure 5 As shown, in one embodiment of this utility model, the connecting block 32 has a driving part 321 at one end facing the limiting block 31. Correspondingly, the limiting block 31 has a connecting groove 314. The connecting block 32 is connected to the limiting block 31 by the driving part 321 being embedded in the connecting groove 314, and the dimension of the connecting groove 314 in the first direction is larger than the dimension of the driving part 321 in the first direction. Figure 6- Figure 8 As shown. Thus, when the connecting block 32 drives the limiting block 31 to slide in the first direction, the driving part 321 abuts against the front sidewall of the connecting groove 314, as... Figure 7 As shown, there is a gap between the fixed plate 33 and the front end face of the limiting block 31 (at this time, because the locking block 312 is held between the folded edge 213 and the bottom plate 211, the limiting block 31 will not twist, and there is a gap between the clearance notch 313 and the bottom plate 211); when the connecting block 32 drives the limiting block 31 to move away from the first direction, the driving part 321 abuts against the rear side wall of the connecting groove 314, as shown. Figure 6 As shown, the fixing plate 33 is embedded in the clearance notch 313, the limiting block 31 cannot be twisted, and even if the locking block 312 passes through the slot 215, the elastic member 34 cannot push the limiting block 31 to make the locking block 312 embedded in the slot 215.
[0060] In one embodiment of this utility model, the connecting block 32 includes an arm portion 322, and the driving portion 321 is connected to the main body portion of the connecting block 32 via the arm portion 322; correspondingly, the front end face of the limiting block 31 has a clearance groove 317 communicating with the connecting groove 314, and when the driving portion 321 is inserted into the connecting groove 314, the arm portion 322 of the connecting block 32 is embedded in the clearance groove 317. The above structure facilitates the assembly of the connecting block 32 and the limiting block 31 together.
[0061] Specifically, the drive portion 321 on the connecting block 32 is rod-shaped and arranged along a second direction (the width direction of the slide rail 21), with the arm portion 322 connected to the middle position of the drive portion 321; correspondingly, the connecting groove 314 is formed by a through groove located on the bottom wall of the clearance notch 313 (the through groove penetrates the width direction of the limiting block 31). The above structure can, to a certain extent, prevent the drive portion 321 from dislodging from the connecting groove 314.
[0062] To further prevent the drive part 321 from coming out of the connecting groove 314, the limiting block 31 also includes an extension 315 located at the opening of the connecting groove 314. The extension 315 is connected to the rear side wall of the connecting groove 314 and extends toward its front side wall, thereby making the opening of the connecting groove 314 relatively small, thereby reducing the probability of the drive part 321 of the connecting block 32 coming out of the connecting groove 314.
[0063] like Figure 4 As shown, in one embodiment of this utility model, the clearance notch 313 of the limiting block 31 is connected to the front end face of the limiting block 31 via a third inclined surface 319. When the first cantilever 12 drives the slider assembly 30 to slide away from the first direction (for example, from sliding towards the first direction to sliding away from the first direction), the fixing plate 33 is guided by the third inclined surface 319 to embed into the clearance notch 313. With the above structure, it is easier to insert the fixing plate 33 into the clearance notch 313 (i.e., between the limiting block 31 and the bottom plate 211 of the slide rail 21).
[0064] After the aforementioned multi-angle limiting sliding support is installed on the window frame and window sash, i.e., the slide rail 21 is fixed to the window frame, the support arm 11 is fixed to the window sash, and the slider assembly 30 is installed on the slide rail, when the window sash is in the closed state, the two locking blocks 312 on the limiting block 31 are respectively located between the folded edge 213 and the bottom plate 211, the driving part 321 of the connecting block 32 abuts against the rear side wall of the connecting groove 314, and at least a portion of the fixing plate 33 is inserted into the clearance notch 313 of the limiting block 31, such as Figure 6 As shown; when the window sash is opened, the first cantilever 12 drives the connecting block 32 and the fixing plate 33 to move in the first direction. At this time, the limiting block 31 remains stationary until the driving part 321 abuts against the front side wall of the connecting groove 314. At the same time, the fixing plate 33 moves out of the clearance notch 313, and then the driving part 321 drives the limiting block 31 to move in the first direction, as shown.Figure 7 As shown in the figure, during the movement of the sliding block assembly 30 driven by the first cantilever 12 towards the first direction, if the clamping blocks 312 pass through the clamping groove 215, the elastic member 34 pushes the limiting block 31 to make the two clamping blocks 312 embedded in the clamping groove 215, at the same time, the limiting block 31 is twisted to make the bottom plate of the avoiding gap abut against the bottom plate 211, as shown in the figure, at this time, the whole sliding block assembly 30 and the first cantilever 12 cannot move towards the first direction, realizing the opening angle limiting; if the first cantilever 12 continues to move towards the first direction, the folded edge at the clamping groove 215 pushes the first inclined surface 3122 to push the clamping blocks 312 back into the space between the folded edge 213 and the bottom plate 211, as shown in the figure, the sliding block assembly 30 can continue to move towards the first direction. Figure 8 When the window is needed to be closed (or the opening angle of the window is needed to be reduced) in the window sash opening limiting state (the clamping blocks 312 are embedded in the clamping groove 215), the sliding block assembly 30 needs to be pulled towards the first direction by the first cantilever 12 first, so that the clamping blocks 312 enter into the space between the folded edge 213 and the bottom plate 211, as shown in the figure, then the first cantilever 12 is pushed towards the reverse direction of the first direction, so that the driving part 321 of the connecting block 32 abuts against the rear side wall of the connecting groove 314, at the same time, at least a part of the fixed plate 33 is inserted into the avoiding gap (during the process, the limiting block 31 remains static), as shown in the figure, then the limiting block is pushed by the driving part 321 to move towards the reverse direction of the first direction, realizing the window closing. Figure 7 Figure 7 Figure 6
[0065] The above is only the preferred specific implementation of the present application, but the protection scope of the present application is not limited to this, any skilled person in the art can easily think of the changes or replacements within the technical range disclosed by the present application, which should be covered in the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
