[0002] Industrial doors serve various purposes in specific industries. They are convenient to use as they are raised and lowered by winches. However, during typhoons, due to the high wind pressure, the door body experiences significant pressure on a large area. By adding reinforcing ribs to the surface of the door body, the pressure resistance requirement can be met. However, when under pressure, the door body is concave, and the rollers that drive the door to rise and fall are compressed within the track, causing one side to collide with the track, resulting in wear and misalignment of the rollers. Based on this, this application provides an industrial door with wind-resistant features. Utility Model Content

[0029] Please see Figures 1-6 Industrial doors serve different purposes in special industries. They are convenient to use as they are raised and lowered by a winch. However, during typhoons, due to the high wind pressure, the door body 2 has a large pressure-bearing area. By setting reinforcing ribs on the surface of the door body 2, the pressure resistance of the door body 2 can be met. However, when under pressure, the door body 2 is concave, and the rollers that drive the door body 2 to rise and fall will be compressed within the track 1, causing one side to abut against the track 1, resulting in wear and misalignment of the rollers. Based on this, this application provides an industrial door windproof pin 3, which includes a door body 2 for sealing and protection. Tracks 1 are set on both the upper and lower parts of the door body 2 to restrict the movement of the door body 2.

[0030] The door body 2 includes a main body 22, with the top and bottom of the main body 22 both provided with a combination strip 21. Rollers are installed on the combination strip 21 and are adapted to the track 1.

[0031] One or more through holes are provided on the outer side of the combination strip 21, and wind-resistant pins 3 are provided;

[0032] The wind-resistant pin 3 includes a pin body 31, which is inserted into the through hole and adapted to the roller to limit the movement of the roller.

[0033] One or more mounting blocks 33 are provided on the outer side of the pin 31. A roller placement area 310 is provided at the mounting block 33 and is adapted to the outer side of the roller.

[0034] Example 1: Design of a single-hole wind-resistant pin 3

[0035] The top and bottom of the door body 22 are each provided with a combination strip 21. Rollers are installed on the combination strip 21 and the rollers are adapted to the track 1. A through hole is opened on the outer side of the combination strip 21, and a windproof pin 3 is inserted into the through hole.

[0036] The pin 31 of the wind-resistant pin 3 is inserted into the through hole and is adapted to the roller to limit the movement of the roller.

[0037] A mounting block 33 is provided on the outer side of the pin 31, and a roller placement area 310 is provided at the mounting block 33, which is adapted to the outer side of the roller.

[0038] Operating steps:

[0039] During the installation of the door body 2, the assembly strip 21 is fixed to the top and bottom of the door body 22.

[0040] Install the roller on the assembly strip 21 and insert the pin 31 of the wind-resistant pin 3 into the through hole of the assembly strip 21 to ensure that the pin 31 is compatible with the roller.

[0041] Place the rollers in the placement area of ​​the mounting block 33, ensuring that the rollers are in a fixed position and preventing them from shaking.

[0042] The single-hole wind-resistant pin design simplifies the installation process and reduces production costs.

[0043] The wind-resistant pin 3 can effectively limit the movement of the rollers and improve the stability of the door 2 under wind pressure.

[0044] Example 2: Design of Multi-hole Wind-resistant Pin 3

[0045] The top and bottom of the door body 22 are provided with two combination strips 21. Each combination strip 21 is equipped with two rollers. The rollers are adapted to the track 1. Two or more through holes are opened on the outer side of each combination strip 21, and two wind-resistant pins 3 are inserted into the through holes.

[0046] Each wind-resistant pin 3 has a pin body 31 inserted into a through hole, which is adapted to the corresponding roller to limit the movement of the roller.

[0047] Each pin 31 has two mounting blocks 33 on its outer side. The mounting blocks 33 have roller placement areas 310 that are adapted to the outer side of the rollers.

[0048] Operating steps:

[0049] During the installation of the door body 2, two combination strips 21 are fixed to the top and bottom of the door body 2 body 22.

[0050] Install the four rollers on the two combination strips 21 respectively, and insert the pins 31 of the four wind-resistant pins 3 into the through holes of the combination strips 21 respectively, ensuring that the pins 31 are compatible with the rollers.

[0051] Place the rollers in the placement areas of the four mounting blocks 33 respectively, ensuring that the rollers are in a fixed position and avoiding shaking.

[0052] The multi-hole wind-resistant pin 3 design increases the support points of the door body 2 and the fixing points of the rollers, significantly improving the wind resistance of the door body 2 under wind pressure. The multi-hole design can disperse wind pressure, reduce the stress on individual rollers and pins 31, and extend service life.

[0053] The wind-resistant pin 3 can effectively restrict the movement of the rollers and improve the stability of the door body 2 under wind pressure. By increasing the number of through holes and mounting blocks 33, the wind-resistant pin 3 can significantly improve the wind resistance of the door body 2. The combination of the wind-resistant pin 3 and the mounting blocks 33 reduces the wear and misalignment of the rollers and extends the service life of the rollers and the door body 2. Multiple through holes and multiple mounting blocks 33 can disperse wind pressure, reduce the force on a single roller and pin 31, and further enhance the wind resistance effect.

[0054] The mounting block 33 is provided with one or more protrusions 39 arranged in a circular array on the side of the roller placement area 310, and the protrusions 39 are adapted to the outer side of the roller.

[0055] A fitting area 32 is provided between the two support blocks 33, and the fitting area 32 is used to control the distance between the two support blocks 33.

[0056] On the side of the roller placement area 310, there is a protrusion 39 arranged in a circular array.

[0057] The protrusion 39 is fitted to the outer side of the roller to further fix the position of the roller.

[0058] A fitting area 32 is provided between the two support blocks 33 to control the spacing between the two support blocks 33.

[0059] Operating steps:

[0060] Place the roller in the placement area of ​​the mounting block 33, ensuring that the protrusion 39 fits the outer side of the roller.

[0061] By adjusting the fitting area 32, the distance between the two mounting blocks 33 is controlled, ensuring that the position of the roller is fixed and stable. Since the outer side of the roller has an annular track 1, the roller can be positioned without affecting the rolling by combining with the protrusion 39. The simple annular protrusion 39 further enhances the fixing effect of the roller and prevents the roller from shifting under wind pressure. The fitting area 32 makes the distance between the mounting blocks 33 adjustable to accommodate rollers of different sizes, improving the flexibility of application. The multi-directional fixed roller design significantly improves the stability of the roller and the wind resistance of the door 2 under wind pressure.

[0062] A positioning block 37 is provided on the outer side of the pin 31, which is located on the outer side of the mounting block 33. A positioning hole 34 is provided on the outer side of the positioning block 37 for inserting fasteners.

[0063] The mounting block 33 is provided with a screw hole 38 at the positioning hole 34 of the positioning block 37. The screw hole 38 is adapted to the fastener thread on the positioning block 37.

[0064] One end of the pin 31 has an insertion area 35. A positioning groove 36 is provided on the outer side of the insertion area 35 at the pin 31. An abutment is installed at the insertion area 35 to fix the pin 31.

[0065] The other end of the pin 31 is provided with a mounting groove 311, and a blocking member is installed at the mounting groove 311 to restrict the other end of the pin 31.

[0066] A positioning block 37 is provided on the outside of the pin 31 and on the outside of the mounting block 33. A positioning hole 34 is provided on the outside of the positioning block 37 for inserting fasteners. A screw hole 38 is provided on the mounting block 33 at the positioning hole 34 of the positioning block 37. The screw hole 38 is adapted to the thread of the fastener inserted into the positioning block 37.

[0067] Operating steps:

[0068] Fix the positioning block 37 to the outside of the mounting block 33, ensuring that the positioning hole 34 of the positioning block 37 is aligned with the screw hole 38 of the mounting block 33.

[0069] Insert the fastener into the positioning hole 34 and screw it into the screw hole 38 to ensure that the positioning block 37 and the mounting block 33 are tightly fixed.

[0070] By setting up positioning blocks 37 and fasteners, the fixing effect of mounting blocks 33 is further enhanced, the stability of the overall structure is improved, the installation steps are simplified, and a firm connection between mounting blocks 33 and pins 31 is ensured.

[0071] A insertion area 35 is provided at one end of the pin body 31, and a positioning groove 36 is provided on the outer side of the insertion area 35 at the pin body 31.

[0072] An abutment is installed at the insertion area 35 to fix the insertion area 35 and the pin 31.

[0073] Operating steps:

[0075] Install the contact element at the insertion area 35 to ensure that the contact element fits tightly with the insertion area 35 and fix the pin 31.

[0076] The design of the insertion area 35 and the abutment further enhances the fixing effect of the pin 31, prevents the pin 31 from shifting under wind pressure, improves the connection stability between the pin 31 and the door 2, and enhances the wind resistance of the overall structure.

[0077] Meanwhile, the other end of the pin 31 is provided with a mounting groove 311, and a blocking member is installed at the mounting groove 311. The blocking member is used to restrict the other end of the pin 31.

[0078] Operating steps:

[0079] Install the blocking component in the mounting slot 311 to ensure that the blocking component fits tightly with the mounting slot 311.

[0080] The blocking component restricts the pin body 31, ensuring that the other end is fixed and preventing the pin body 31 from shifting under wind pressure.

[0081] The combination of mounting groove 311 and blocking component further enhances the fixing effect of pin 31, prevents pin 31 from shifting under wind pressure, improves the connection stability between pin 31 and door 2, and enhances the wind resistance of the overall structure.

[0082] The design of positioning block 37, fasteners, insertion area 35, abutting parts, mounting groove 311 and blocking parts further enhances the fixing effect of pin 31 and mounting block 33, prevents displacement under wind pressure, significantly improves the connection stability between pin 31, mounting block 33 and door 2, and enhances the wind resistance of the overall structure.

[0083] The design of the positioning block 37 and the fasteners simplifies the installation steps of the mounting block 33 and the pin 31, ensuring a secure connection between them.

[0084] Multiple fixing mechanisms effectively prevent the pin 31 and roller from shifting under wind pressure, significantly improving the wind resistance of the industrial door.
