Description

Technical Field

[0001] The invention relates to the technical field of grating plates, in particular to an anti-slip grating plate. Background Art

[0002] Steel grating is an open steel structure that is an orthogonal combination of load-bearing flat steel and cross bars at a certain interval and fixed by welding or compression locking. It has the characteristics of high load-bearing capacity, good lighting and ventilation effects, durability, beauty and practicality. Steel grating is usually made of carbon steel, stainless steel, aluminum and other materials. The surface can be hot-dip galvanized, sprayed and other treatments to enhance its corrosion resistance. In terms of safety performance, its use function can be improved by adding anti-slip and anti-dirt properties during the design and manufacturing process. The flexible design of steel grating allows it to be customized in size, shape and load-bearing capacity according to needs. It is widely used in industrial platforms, stair treads, equipment protection and other fields. In addition, it is also used in urban planning such as drain ditch covers, pedestrian overpasses, municipal manhole covers, etc. to meet different engineering and aesthetic needs. Steel grating plays an important role in modern construction and industrial applications due to its efficient performance and economic benefits.

[0003] Existing metal grating plates are usually designed to be welded by flat steel and metal cross bars to form multiple repeated small rectangular units, which are assembled into a large rectangular structure, and the anti-skid effect is achieved by opening carved patterns on the surface of the metal cross bars. The structure of the existing device is relatively simple. When multiple grating plates need to be spliced, grating plates of the same size are usually placed side by side and used directly, or holes are punched at their connections and the grating plates are firmly fixed together with bolts. Although this method is relatively simple in operation, it requires operators to repeatedly punch holes on the outside of the grating plates when splicing them, and connect the multiple grating plates together with bolts. This splicing method may have some problems. First, multiple punching may weaken the structural integrity of the grating plate, especially in situations where it is loaded or subjected to impact, which may affect its durability and safety. Secondly, as the use time increases, the bolts may loosen due to external environmental factors such as corrosion or vibration, thereby affecting the stability and anti-skid performance of the splicing. In view of this, we provide an anti-skid grating plate. Summary of the invention

[0015] Compared with the prior art, the anti-slip grating plate has the following beneficial effects:

[0016] 1. The present invention places the anti-skid cross bar on the top of the grille frame through the semi-lunar groove on the top surface of the grille frame, with one side of the anti-skid groove opened on the anti-skid cross bar facing upwards, and rotates the bidirectional screw rod located at the top end inside the grille frame to respectively drive multiple groups of corresponding positioning plug-ins at the top end of the limit frame along the outer wall of the limit frame to move toward the anti-skid cross bar between the positioning plug-ins, and insert one side of the top of the positioning plug-in into the positioning slot, so that the anti-skid cross bar is stably and firmly installed on the top of the grille frame, so that with the continuous rotation of the bidirectional screw rod, the positioning plug-in is gradually inserted into the positioning slot of the anti-skid cross bar until it is completely tightened.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] like Figure 1-7 As shown, the present invention provides a technical solution: an anti-skid grating plate, comprising a grating frame 1, wherein the grating frames 1 have two grating frames 1, and the two grating frames 1 are slidably connected to each other, the top end of the interior of the grating frame 1 is rotated to connect with a plurality of bidirectional screw rods 2, and the top surfaces of the grating frames 1 are respectively provided with a plurality of semi-lunar grooves 201, the top end of the interior of the grating frame 1 is engaged with an anti-skid cross bar 202 through the semi-lunar grooves 201, and the bottom end of the interior of the anti-skid cross bar 202 corresponds to the semi-lunar grooves 201, and the top surface of the anti-skid cross bar 202 is provided with a plurality of anti-skid grooves 203, a group of corresponding connecting frames 3 are fixedly connected to both sides of the outer wall of the grating frame 1, and a group of corresponding connecting plug-ins 301 are fixedly connected to the outer wall of one end of the connecting frame 3, the connecting plug-in 301 is located at one end inside the other connecting frame 3, one side of the outer wall of the connecting plug-in 301 is connected through and inside the end of the connecting frame 3, and the inner end of the connecting frame 3 is slidably connected to the outer wall of one side of the connecting plug-in 301.

[0030] With one side of the anti-skid groove 203 of the anti-skid cross bar 202 facing upwards, the anti-skid cross bar 202 is placed on the top of the grille frame 1 through the semi-moon groove 201 on the top surface of the grille frame 1, and the groove at the bottom end of the anti-skid cross bar 202 corresponds to the semi-moon groove 201, so that the grille frame 1 is clamped with the anti-skid cross bar 202 through the semi-moon groove 201;

[0031] After it is limited at the top of the grid frame 1, the bidirectional screw rod 2 located at the top of the grid frame 1 is rotated by the hexagonal wrench. Since a set of limit frames 204 are respectively arranged on both sides of the inner wall of the grid frame 1, the limit frame 204 is penetrated with the inner side of the positioning plug-in 205 and the inner side of the positioning plug-in 205 is slidably connected with the outer wall side of the limit frame 204. The positioning plug-in 205 is limited by the limit frame 204, so that the positioning plug-in 205 can only move horizontally along the outer wall of the limit frame 204;

[0032] As the operator rotates the bidirectional screw rod 2, the bidirectional screw rod 2 drives the corresponding multiple groups of positioning plug-ins 205 at the top of the inner top of the limit frame 204 through the multiple groups of bidirectional threads arranged on the outer wall thereof, respectively, to move along the outer wall of the limit frame 204 toward the anti-slip cross bar 202 between the positioning plug-ins 205, and as the bidirectional screw rod 2 rotates, the top side of the positioning plug-in 205 is inserted into the positioning slot 206 located on one side of the inner side of the anti-slip cross bar 202, so that the anti-slip cross bar 202 is stably and firmly installed on the top of the grille frame 1;

[0033] Move one end of the connecting frame 3 fixed with the connecting plug 301 close to the outer wall of one end of the other connecting frame 3, and insert the connecting plug 301 into the other connecting frame 3. Since a plurality of guide frames 302 are fixedly connected to one end of the connecting frame 3, the connecting fastener 303 is limited by penetrating the guide frame 302 and one side of the inner part of the connecting fastener 303.

[0034] When the connecting fastener 303 moves, it can only slide along the outer wall of the guide frame 302, and a tension spring 304 is arranged between the connecting fastener 303 and the inner wall of the connecting frame 3. After the connecting plug 301 is inserted into the connecting frame 3, the inclined surface of one side of the connecting plug 301 and one end of the inclined surface of the connecting fastener 303 are attached to and abut against each other. As the connecting plug 301 is inserted, the connecting plug 301 pushes the connecting fastener 303 to move along the outer wall of the guide frame 302 away from the outer wall of the end of the tension spring 304 through the inclined outer wall.

[0035] When the outer walls of the two connecting frames 3 collide, since one side of the outer wall of the connecting fastener 303 loses the thrust from the outer wall of the connecting plug 301, the connecting plug 301 is pulled toward itself along the outer wall of the guide frame 302 by the force of the tension spring 304 itself, so that the connecting fastener 303 and the connecting plug 301 are engaged and connected, and the two connecting frames 3 and the grid frame 1 are spliced ​​by the mutual engagement of the connecting fastener 303 and the connecting plug 301;

[0036] The sliding button 305 is slid away from the connecting plug 301. Since the guide frame 302 limits the connecting fastener 303 by itself, as the sliding button 305 moves, the sliding shafts 307 on both sides of the outer wall of the sliding button 305 penetrate the oblique groove 306 and are slidably connected with one end inside thereof. Through the cooperation between the sliding shafts 307 and the oblique groove 306, the connecting fastener 303 is driven to move along the outer wall of the guide frame 302 away from the tension spring 304.

[0037] Separate the connecting plug 301 from the connecting fastener 303. At this time, the two grille frames 1 can be moved to both sides to separate them. Through the cooperation of the interlocking mechanism of the inclined surfaces among the tension spring 304, the connecting plug 301 and the connecting fastener 303, the device can realize the rapid splicing of the two grille frames 1 and ensure the stability of the splicing. In addition, in terms of stability, the device ensures that the grille frame 1 can withstand pressure and tension from different directions during use. When the two grille frames 1 are tightly spliced ​​by the connecting plug 301 and the connecting fastener 303, the tension spring 304 provides additional vibration resistance and tensile strength, making the structure more stable. In terms of impact resistance, the interlocking mechanism of the inclined surfaces can effectively disperse the impact force, reduce the impact of direct impact on the splicing structure, and ensure that the grille frame 1 is not easily displaced during the splicing process, thereby improving the firmness and safety of the overall structure, so that the structure of the entire grille frame 1 is not only stable but also has good impact resistance, which is suitable for industrial environments with higher requirements.

The top end of the interior of the grid frame 1 is slidably connected to the two sides of the outer wall of the positioning plug-in 205 through the limit frame 204 and the two-way screw rod 2. A group of corresponding positioning slots 206 are provided on both sides of the outer wall of the anti-slip cross bar 202, and the anti-slip cross bar 202 is located at the top of one side of the positioning plug-in 205. The positioning slot 206 corresponds to the positioning plug-in 205, and the corresponding surface side of the positioning plug-in 205 is slidably connected to one side of the inner wall of the positioning slot 206.

[0039] With one side of the anti-skid groove 203 of the anti-skid cross bar 202 facing upwards, the anti-skid cross bar 202 is placed on the top of the grille frame 1 through the semi-moon groove 201 on the top surface of the grille frame 1, and the groove at the bottom end of the anti-skid cross bar 202 corresponds to the semi-moon groove 201, so that the grille frame 1 is clamped with the anti-skid cross bar 202 through the semi-moon groove 201;

[0040] After it is limited at the top of the grid frame 1, the bidirectional screw rod 2 located at the top of the grid frame 1 is rotated by the hexagonal wrench. Since a set of limit frames 204 are respectively arranged on both sides of the inner wall of the grid frame 1, the limit frame 204 is penetrated with the inner side of the positioning plug-in 205 and the inner side of the positioning plug-in 205 is slidably connected with the outer wall side of the limit frame 204. The positioning plug-in 205 is limited by the limit frame 204, so that the positioning plug-in 205 can only move horizontally along the outer wall of the limit frame 204;

[0041] As the operator rotates the bidirectional screw rod 2, the bidirectional screw rod 2 drives the multiple groups of corresponding positioning plug-ins 205 at the top of the inner top of the limit frame 204 along the outer wall of the limit frame 204 through the multiple groups of bidirectional threads arranged on its outer wall, and moves toward the anti-slip cross bar 202 between the positioning plug-ins 205. As the bidirectional screw rod 2 rotates, the top side of the positioning plug-in 205 is inserted into the positioning slot 206 located on one side of the inner side of the anti-slip cross bar 202, and the anti-slip cross bar 202 is stably and firmly installed on the top of the grid frame 1, so that as the bidirectional screw rod 2 continues to rotate, the positioning plug-in 205 is The positioning plug-in 205 is gradually inserted into the positioning slot 206 of the anti-slip cross bar 202 until it is completely tightened. At this time, the connection between the anti-slip cross bar 202 and the grille frame 1 reaches the optimal stable state, ensuring the anti-slip effect and the stability of the overall structure in various working environments. Through the cooperation between the anti-slip cross bar 202 and the positioning plug-in 205, the device can not only improve the installation efficiency, but also realize the fast and reliable installation and disassembly of the anti-slip cross bar 202 while ensuring safety, which greatly improves the practicality of the metal grille plate and the convenience of maintenance.

[0043] Move one end of the connecting frame 3 fixed with the connecting plug 301 close to the outer wall of one end of the other connecting frame 3, and insert the connecting plug 301 into the other connecting frame 3. Since a plurality of guide frames 302 are fixedly connected to one end of the connecting frame 3, the connecting fastener 303 is limited by penetrating the guide frame 302 and one side of the inner part of the connecting fastener 303.

[0044] When the connecting fastener 303 moves, it can only slide along the outer wall of the guide frame 302, and a tension spring 304 is arranged between the connecting fastener 303 and the inner wall of the connecting frame 3. After the connecting plug 301 is inserted into the connecting frame 3, the inclined surface of one side of the connecting plug 301 and one end of the inclined surface of the connecting fastener 303 are attached to and abut against each other. As the connecting plug 301 is inserted, the connecting plug 301 pushes the connecting fastener 303 to move along the outer wall of the guide frame 302 away from the outer wall of the end of the tension spring 304 through the inclined outer wall.

[0052] When the connecting fastener 303 moves, it can only slide along the outer wall of the guide frame 302, and a tension spring 304 is arranged between the connecting fastener 303 and the inner wall of the connecting frame 3. After the connecting plug 301 is inserted into the connecting frame 3, the inclined surface of one side of the connecting plug 301 and one end of the inclined surface of the connecting fastener 303 are attached to and abut against each other. As the connecting plug 301 is inserted, the connecting plug 301 pushes the connecting fastener 303 to move along the outer wall of the guide frame 302 away from the outer wall of the end of the tension spring 304 through the inclined outer wall.

[0053] When the outer walls of the two connecting frames 3 collide, since one side of the outer wall of the connecting fastener 303 loses the thrust from the outer wall of the connecting plug 301, the connecting plug 301 is pulled toward itself along the outer wall of the guide frame 302 by the force of the tension spring 304 itself, so that the connecting fastener 303 and the connecting plug 301 are engaged and connected, and the two connecting frames 3 and the grid frame 1 are spliced ​​by the mutual engagement of the connecting fastener 303 and the connecting plug 301;

[0054] The sliding button 305 is slid away from the connecting plug 301. Since the guide frame 302 limits the connecting fastener 303 by itself, as the sliding button 305 moves, the sliding shafts 307 on both sides of the outer wall of the sliding button 305 penetrate the oblique groove 306 and are slidably connected with one end inside thereof. Through the cooperation between the sliding shafts 307 and the oblique groove 306, the connecting fastener 303 is driven to move along the outer wall of the guide frame 302 away from the tension spring 304.

[0055] Separate the connecting plug 301 from the connecting fastener 303. At this time, move the two grid frames 1 to both sides to separate them. Through the interlocking mechanism of the inclined surfaces of the tension spring 304, the connecting plug 301 and the connecting fastener 303, the device can quickly splice the two grid frames 1 to ensure the stability of the splicing.

[0056] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
