Description

Technical Field

[0001] This invention relates to the field of roof walkway technology, specifically a quick-release buckle structure for prefabricated roof walkways. Background Technology

[0002] Roof walkways are a type of safe passageway for maintenance workers to walk on the roof during inspection and cleaning. They provide a safe, non-slip, green walking path for roof workers. The walkway distributes the load of pedestrians on the roof surface, protecting the roof from unnecessary damage and preventing people from falling.

[0003] The existing roof walkways are mainly installed on the roof joists with bolts and nuts. Although bolts and nuts can play a locking role, since the walkways themselves are exposed to the roof, they are prone to corrosion and damage under the adverse conditions of wind and rain. This can lead to stripping, loosening, and falling off of the bolts and nuts, which makes it extremely easy for the walkways to separate from the roof joists, posing a safety hazard and creating certain dangers for maintenance personnel when inspecting and cleaning the roof.

[0004] In addition, a large number of bolts and nuts are used when installing and locking the walkway to the roof joists. This method requires a lot of manpower and time, significantly increasing the labor intensity and resulting in extremely low efficiency. This is especially true when installing the walkway at a 90° angle, which is even more cumbersome. Therefore, it is necessary to provide a quick-release buckle structure for prefabricated roof walkways to solve the above-mentioned technical problems. Summary of the Invention

[0005] The purpose of this invention is to provide a quick-release buckle structure for prefabricated roof walkways, in order to solve the problems mentioned in the background art, such as the cumbersome installation, low efficiency, and extreme risk of safety issues associated with existing roof walkways. This invention provides a solution that is significantly different from existing technologies, addressing the problem that existing solutions are too simplistic.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a quick-release buckle structure for prefabricated roof walkways, comprising a base support, railings installed on both the front and rear sides above the base support, a lifting rod slidably connected to the inner side of the railings, a pressing rod provided on the inner side below the lifting rod, a third spring clamped on the outer side of the pressing rod, a lifting block installed on the outer side of the lifting rod, a locking mechanism provided on the inner side of the lifting block, a push plate installed on the upper inner side of the base support, a driving mechanism provided on the left side inside the base support, and a locking mechanism installed on the upper right side of the push plate.

[0007] In a further embodiment, a first dovetail groove is provided on the upper inner wall of the bottom support, and a slot is provided on the right side of the bottom support. A first pressing rod is installed on the upper inner side of the slot, and a first spring is engaged on the outer side of the first pressing rod.

[0008] In a further embodiment, a second spring is engaged above the outer side of the lifting rod.

[0009] In a further embodiment, a frustum is connected above the lifting block, and a second dovetail groove is provided on the inner side of the bottom of the lifting block.

[0010] In a further embodiment, the locking mechanism includes a locking block slidably connected to the inner side of the second dovetail groove, and a push rod is installed above one side of the locking block. A compression sleeve is provided on the outer side of the push rod, and one end of the compression sleeve is connected to the left and right sides of the lifting rod. The compression sleeve and the push rod form a sealed sliding structure.

[0011] In a further embodiment, the bottom of the push plate is equidistantly hinged with bosses, and the area below the bosses is arc-shaped. The top of the push plate and the first dovetail groove form a left-right sliding structure.

[0012] In a further embodiment, the driving mechanism includes an oil cavity disposed on the left side inside the bottom support, and a pressing block is slidably connected to the upper inner side of the oil cavity. A fourth spring is engaged on the outer side of the pressing block. An oil pipe is connected to the lower right side of the oil cavity, and a limiting sleeve is installed on the upper right side of the oil cavity. The bottom left side of the limiting sleeve is connected to the oil pipe.

[0013] In a further embodiment, the engaging mechanism includes a fifth spring mounted on the right end above the push plate, and a locking block is mounted above the fifth spring, the locking block and the locking groove forming an engaging structure.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. This invention includes a locking mechanism and a driving mechanism. By using a foot to press down on the block in conjunction with a fourth spring, the oil inside the oil chamber is effectively squeezed through the oil pipe to the inside of the limiting sleeve. This pushes the push plate and boss to the right in conjunction with the first dovetail groove. Multiple bosses effectively press the corresponding lifting blocks downwards under the inclined guidance of the truncated cone, thereby simultaneously lowering the locking mechanism, the pressing rod, and the third spring. When the boss moves to the plane above the truncated cone, the roof joists can press the pressing rod upwards in conjunction with the third spring, drawing the oil from the lower inside of the pressing sleeve into the lifting block. The inner side of the rod effectively drives the push rods and locking blocks on both sides below the lifting rod to move relative to each other, so that the locking blocks can quickly lock the corresponding roof joists on both sides. At this time, the locking block on the right end of the push plate, in conjunction with the elastic extension and contraction of the fifth spring at the bottom, can lock the locking block into the slot on the right side of the bottom support, thereby limiting and locking each set of locking blocks to the corresponding roof joists on both sides. Compared with the existing technology, it allows the operator to lock the locking blocks at the bottom of the walkway to the corresponding roof joists on both sides in the most labor-saving way, while improving the stability of the walkway, thereby increasing the overall practicality and convenience.

[0016] 2. This invention is equipped with a first pressing rod and a first spring. When the walkway needs to be disassembled, the operator only needs to step on the first pressing rod, causing the first pressing rod to move downward in conjunction with the first spring. This effectively pushes the locking block downward in conjunction with the fifth spring. At this time, the locking block, push plate, and boss move to the left under the elastic reset of the fourth spring and separate from the slot, thereby effectively separating the boss from the top of the truncated cone. At this time, the lifting block, truncated cone, and locking mechanism move upward under the elastic reset of the second spring, thereby allowing the locking mechanism to unlock and disassemble the corresponding roof joists. Compared with the existing technology, this invention allows the operator to unlock and disassemble each set of locking blocks from the corresponding roof joists in the most labor-saving way, thereby improving the efficiency of walkway installation and disassembly.

[0017] 3. This invention features a lifting rod. When the walkway needs to be repositioned 90°, since the roof joists remain in place, the walkway can be easily repositioned and installed on the roof. Simply rotate the entire walkway 90°, aligning the center of the square grooves on both sides of the walkway's bottom with the longitudinal center of the roof joists. Then, manually rotate the lifting rod 90° sequentially to ensure each locking block is positioned on either side of the roof joists. Finally, lock the locking mechanism onto both sides of the roof joists in the same manner. Compared to existing technologies, this invention allows operators to easily reposition the walkway 90°, facilitates extensive roof cleaning and maintenance, makes the device more marketable, improves application effectiveness, and increases installation efficiency.

Detailed Implementation

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Please see Figure 1-8 One embodiment of the present invention provides a quick-release buckle structure for a prefabricated roof walkway, comprising a base support 1, a first dovetail groove 101, a slot 102, a first pressing rod 103, a first spring 104, a railing 2, a lifting rod 3, a second spring 301, a pressing rod 4, a third spring 5, a lifting block 6, a frustum 601, a second dovetail groove 602, a locking mechanism 7, a locking block 701, a push rod 702, a pressing sleeve 703, a push plate 8, a boss 801, a drive mechanism 9, an oil chamber 901, a pressing block 902, a fourth spring 903, and an oil... The bottom support 1 has a tube 904, a limiting sleeve 905, a locking mechanism 10, a fifth spring 1001, and a locking block 1002. The bottom support 1 is equipped with railings 2 on both the front and rear sides. The railings 2 are slidably connected to the inner side of the railings 2. The inner side of the lower part of the lifting rod 3 is provided with a pressing rod 4. The outer side of the pressing rod 4 is locked with a third spring 5. The outer side of the lifting rod 3 is equipped with a lifting block 6. The inner side of the lifting block 6 is provided with a locking mechanism 7. The bottom support 1 is equipped with a push plate 8 on the upper inner side. The bottom support 1 is equipped with a drive mechanism 9 on the left side inside. The push plate 8 is equipped with a locking mechanism 10 on the upper right side. Example 1

[0029] Please see Figure 1-8The bottom support 1 has a first dovetail groove 101 on its inner upper wall and a slot 102 on its right side. A first pressing rod 103 is installed on the upper inner side of the slot 102, and a first spring 104 is secured on the outer side of the first pressing rod 103. A second spring 301 is secured on the upper outer side of the lifting rod 3. A frustum 601 is connected above the lifting block 6, and a second dovetail groove 602 is provided on the inner bottom side of the lifting block 6. The locking mechanism 7 includes a locking block 701 slidably connected to the inner side of the second dovetail groove 602. A push rod 702 is installed on the upper side of one side of the locking block 701. A compression sleeve 703 is provided on the outer side of the push rod 702, and one end of the compression sleeve 703 is connected to the left and right sides of the lifting rod 3. The compression sleeve 703 and the push rod 702 form a sealed sliding structure. The bottom of the plate 8 is equidistantly hinged with bosses 801, and the lower part of the bosses 801 is arc-shaped. The upper part of the push plate 8 and the first dovetail groove 101 form a left-right sliding structure. The drive mechanism 9 includes an oil cavity 901 located on the left side inside the bottom support 1, and a pressing block 902 is slidably connected to the upper inner side of the oil cavity 901. A fourth spring 903 is engaged on the outer side of the pressing block 902. An oil pipe 904 is connected to the lower right side of the oil cavity 901, and a limiting sleeve 905 is installed on the upper right side of the oil cavity 901. The lower left side of the bottom of the limiting sleeve 905 is connected to the oil pipe 904. The locking mechanism 10 includes a fifth spring 1001 installed on the right side above the push plate 8, and a locking block 1002 is installed above the fifth spring 1001. The locking block 1002 and the locking groove 102 form a locking structure. When installing the walkway on the roof, the device is first placed manually on the roof. Since the spacing of the roof joists is pre-measured, the spacing of the square grooves at the bottom of the device is designed based on the known roof joist spacing. The center of the square grooves at the bottom is aligned with the horizontal center of the roof joists. Then, the foot is used to press down on the pressing block 902 in conjunction with the fourth spring 903, squeezing the oil inside the oil chamber 901. This causes the oil inside the oil chamber 901 to be squeezed through the oil pipe 904 to the inside of the limiting sleeve 905. As the amount of oil inside the limiting sleeve 905 increases, it pushes the push plate 8 and the boss 801 to the right in conjunction with the first dovetail groove 101, allowing the multiple bosses 801 to effectively position the corresponding lifting blocks 6 on the truncated cone. Under the inclined guidance of 601, the lifting block 6 is pressed downwards. When the lifting block 6 descends, it can drive the locking mechanism 7, the pressing rod 4, and the third spring 5 to descend simultaneously. The locking mechanism 7 here includes a locking block 701, a push rod 702, and a pressing sleeve 703. When the boss 801 moves above the inclined surface of the frustum 601, each set of locking blocks 701 is positioned on both sides of each roof joist. When the boss 801 moves to the plane above the frustum 601, the pressing rod 4, in conjunction with the third spring 5, presses against the roof joist, causing the pressing rod 4 to move upwards. This draws the oil from the lower inner side of the pressing sleeve 703 to the lower inner side of the lifting rod 3, thereby driving the push rods 702 and the locking blocks 701 on both sides below the lifting rod 3 to move relative to each other simultaneously.This effectively locks the locking blocks 701 onto both sides of the corresponding roof joists. When the boss 801 moves to the flat area at the top of the truncated cone 601, the locking block 1002 at the right end of its push plate 8, in conjunction with the elastic extension and contraction of the fifth spring 1001 at the bottom, can precisely engage the locking block 1002 inside the slot 102 on the right side of the bottom support 1. This limits and locks each set of locking blocks 701 to the corresponding sides of the roof joists. Through this structure, the operator can lock the locking blocks 701 at the bottom of the walkway onto both sides of the corresponding roof joists in the least effortful way, while simultaneously improving the stability of the walkway, thereby increasing the overall practicality and stability. Example 2

[0030] Please see Figure 4 and Figure 7 The first pressing rod 103 is fitted with a first spring 104 on its outer side. The locking mechanism 10 includes a fifth spring 1001 installed on the right side above the push plate 8, and a locking block 1002 is installed above the fifth spring 1001. The locking block 1002 and the locking groove 102 form a locking structure. When the walkway needs to be disassembled, the operator only needs to step on the first pressing rod 103. At this time, the first pressing rod 103 moves downward in conjunction with the first spring 104, and presses the locking block 1002 downward in conjunction with the fifth spring 1001. At this time, the locking block 1002 and the push plate 8 move to the left under the elastic reset of the fourth spring 903, and separate from the locking groove 102. When the push plate 8 moves to the left, it can also drive the boss 801 to move to the left, thereby separating the boss 801 from the top of the truncated cone 601. Then, the lifting block 6, the truncated cone 601 and the locking mechanism 7 move upward under the elastic reset of the second spring 301, thereby locking the mechanism. 7. Unlock and disassemble the corresponding roof joists. The above structure allows operators to unlock and disassemble each locking block 701 with the corresponding roof joist using the least effort, thus improving the efficiency of walkway installation and disassembly. When the walkway needs to be repositioned 90°, since the roof joist position remains unchanged, when installing the walkway on the roof at a 90° angle, first rotate the entire walkway 90°, aligning the center of the square grooves on both sides of the bottom of the walkway with the longitudinal center of the roof joist. Then, manually rotate the lifting rod 3 90° sequentially, ensuring that each locking block 701 is positioned on both sides of the roof joist. Lock the locking mechanism 7 on both sides of the roof joist using the same method. This structure allows operators to easily install the walkway at a 90° angle, facilitating large-scale cleaning and maintenance of the roof, and making the device more marketable.

[0031] Working principle: such as Figure 1-8As shown, when installing the walkway on the roof, the device is first placed manually on the roof. Since the spacing of the roof joists is pre-measured, the spacing of the square groove at the bottom of the device is designed based on the known roof joist spacing. At this time, the center of the square groove at the bottom is aligned with the horizontal center of the roof joists. Then, the foot is used to step on the pressing block 902 in conjunction with the fourth spring 903, squeezing the oil inside the oil chamber 901. This causes the oil inside the oil chamber 901 to be squeezed through the oil pipe 904 to the limiting sleeve 905. Inside, as the oil inside the limiting sleeve 905 increases, it can push the push plate 8 and the boss 801 to the right in conjunction with the first dovetail groove 101, so that the multiple bosses 801 can effectively squeeze the corresponding lifting blocks 6 downward under the inclined guidance of the frustum 601. When the lifting blocks 6 descend, they can drive the locking mechanism 7, the pressing rod 4 and the third spring 5 to descend simultaneously. The locking mechanism 7 here includes a locking block 701, a push rod 702 and a pressing sleeve 703. When the boss 801 moves above the inclined surface of the frustum 601, it can make each The locking blocks 701 are located on both sides of each roof joist. When the boss 801 moves to the plane above the frustum 601, the pressing rod 4, in conjunction with the third spring 5, presses against the roof joist, causing the pressing rod 4 to move upward. This draws the oil from the lower inner side of the pressing sleeve 703 to the lower inner side of the lifting rod 3, thereby causing the push rods 702 and locking blocks 701 on both sides of the lower part of the lifting rod 3 to move relative to each other. This effectively locks the corresponding roof joist on both sides with the locking blocks 701. When the boss 801... When the push plate 8 moves to the flat area at the top of the truncated cone 601, the locking block 1002 at the right end of the push plate 8, in conjunction with the elastic extension and retraction of the fifth spring 1001 at the bottom, can lock the locking block 1002 into the slot 102 on the right side of the bottom support 1. This locks each set of locking blocks 701 to the corresponding roof joists on both sides. Through the above structure, the operator can lock the locking blocks 701 at the bottom of the walkway to the corresponding roof joists on both sides in the most labor-saving way, and at the same time improve the stability of the walkway, thereby increasing the overall practicality and stability.

[0032] Conversely, when the walkway needs to be disassembled, the operator only needs to step on the first pressing rod 103. At this time, the first pressing rod 103 moves downward with the first spring 104 and presses the locking block 1002 downward with the fifth spring 1001. At this time, the locking block 1002 and the push plate 8 move to the left under the elastic reset of the fourth spring 903 and separate from the slot 102. When the push plate 8 moves to the left, it can also drive the boss 801 to move to the left, thereby separating the boss 801 from the top of the truncated cone 601. Then, the lifting block 6, the truncated cone 601 and the locking mechanism 7 move upward under the elastic reset of the second spring 301, thereby allowing the locking mechanism 7 to unlock and disassemble the corresponding roof joists. Through the above structure, the operator can unlock and disassemble each set of locking blocks 701 with the corresponding roof joists in the most labor-saving way, thereby improving the efficiency of walkway installation and disassembly.

[0033] When the walkway needs to be repositioned by 90°, since the position of the roof joists remains unchanged, when installing the walkway on the roof with a 90° repositioning, first rotate the entire walkway by 90° and align the center of the square grooves on both sides of the bottom of the walkway with the longitudinal center of the roof joists. Then, manually rotate the lifting rod 3 by 90° in sequence so that each set of locking blocks 701 can be located on both sides of the roof joists. Then, lock the locking mechanism 7 on both sides of the roof joists in the same way as described above. Through the above structure, it is convenient for operators to install the walkway with a 90° repositioning in the most convenient way, which facilitates the operators to carry out large-scale cleaning and maintenance of the roof, and makes the device more suitable for the market.
