Description

Technical Field

[0001] The utility model relates to the technical field of equipment protection, in particular to an equipment protection structure and an industrial control equipment. Background Technique

[0002] Many industrial control equipments are assembled by multiple structural parts. Inevitably, the screw fastening method is used during the assembly process. In this way, mounting holes for screw fastening need to be provided on the structural parts so as to fix multiple structural parts through screws, thereby assembling into a complete equipment. However, after the equipment is assembled, since the screws are exposed outside the mounting holes, foreign matters such as dust and water in the outside are likely to enter, affecting the service life of the equipment, and the mounting holes on the structural parts are still visible to the naked eye, which also affects the appearance of the equipment.

[0003] To solve this problem, in the prior art, usually a soft silicone or a plug with an elastic wall is arranged in the exposed mounting hole. The soft silicone or the plug is fixed in the mounting hole by means of soft glue interference, elastic wall snap or back glue auxiliary bonding, etc., so as to protect the internal structural features of the mounting hole and play a role in aesthetics.

[0004] Although the above methods can achieve better protection and aesthetic effects, when the soft silicone or the plug needs to be disassembled during equipment maintenance, it can only be pried open from the place where the soft silicone or the plug is matched with the mounting hole, which makes it difficult to disassemble the soft silicone or the plug from the structural part, and even a destructive disassembly or it cannot be disassembled at all, which is not convenient for the installation and maintenance of the equipment, thus increasing the installation and maintenance cost of the equipment. Content of the Utility Model

[0005] The main purpose of the utility model is to propose an equipment protection structure and an industrial control equipment, aiming to reduce the installation and maintenance cost of the equipment.

[0006] To achieve the above object, an equipment protection structure proposed by the utility model includes:

[0007] A first structural part, on which a mounting hole is formed, and a first stepped guiding chute is formed on the inner peripheral surface of the mounting hole;

[0008] A second structural part, which is installed in the mounting hole, a force-applying structure is formed on the upper surface of the second structural part, a second stepped guiding chute is formed on the outer peripheral surface of the second structural part, and the first stepped guiding chute is engaged with the second stepped guiding chute which is matched with it.

[0009] In an embodiment, the first stepped guiding chute is a groove, and the second stepped guiding chute is a convex groove.

[0010] In one embodiment, chamfers are formed on at least one side of the second stepped guiding chute.

[0011] In one embodiment, the number of the first stepped guiding chute and the second stepped guiding chute is at least two.

[0012] In one embodiment, the shapes of the first stepped guiding chute and the second stepped guiding chute are any one of trapezoidal, circular and spherical.

[0013] In one embodiment, a limiting structure is formed on the inner peripheral surface of the mounting hole of the first structural member or the outer peripheral surface of the second structural member.

[0014] In one embodiment, the limiting structure is formed on the outer peripheral surface of the second structural member and is tangent to the outer peripheral surface of the second structural member, and the thickness of the limiting structure is gradually decreased from one end close to the upper surface of the second structural member to one end far from the upper surface of the second structural member.

[0015] In one embodiment, the cross-sectional area of the limiting structure is gradually decreased from one end close to the upper surface of the second structural member to one end far from the upper surface of the second structural member.

[0016] In one embodiment, the force-applying structure is in a shape of a single character or a cross.

[0017] The present utility model further provides an industrial control device, and the industrial control device includes the device protection structure as described above.

[0018] The device protection structure provided by the present utility model forms a first stepped guiding chute on the inner peripheral surface of the mounting hole on the first structural member, forms a second stepped guiding chute on the outer peripheral surface of the second structural member which is matched with the first structural member, the first stepped guiding chute is clamped with the second stepped guiding chute, and simultaneously a force-applying structure is formed on the upper surface of the second structural member. In this way, when the second structural member needs to be removed for equipment maintenance, a force-applying tool can be placed in the force-applying structure on the second structural member, and then the force-applying tool is rotated. At this time, the mutually matched first guiding chute and second guiding chute will contact each other and generate an outward thrust force, prompting a relative movement between the first structural member and the second structural member, so that the second structural member can be easily rotated out of the mounting hole of the first structural member, greatly facilitating the installation and maintenance of the equipment and reducing the cost of equipment installation and maintenance.

[0033] In addition, the technical solutions between the various embodiments of the present utility model can be combined with each other, but it must be based on the ability of those of ordinary skill in the art to implement. When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the embodiments of the present utility model.

[0034] To better understand the above technical solutions, the above technical solutions will be described in detail below with reference to the accompanying drawings.

[0035] As Figure 1 shown, during the assembly process of industrial control equipment, a plurality of structural parts are fixed by using screw fastening to assemble into a complete device. The first structural part 10 is a device using screw fastening. After the device is assembled, the mounting holes 11 for screw fastening on the first structural part 10 are exposed, and foreign matters such as dust and water in the outside world are likely to enter, affecting the service life of the device. Moreover, the mounting holes 11 are still visible to the naked eye, which also affects the aesthetics of the device.

[0036] Therefore, in related technologies, a second structural member 20 is usually disposed in the mounting hole 11, such as soft silicone or a plug with an elastic wall. The soft silicone or the plug is fixed in the mounting hole by means of soft glue interference, elastic wall snap, or adhesive auxiliary bonding, etc., so as to protect the internal structural features of the mounting hole 11 and play a role in aesthetics. Although this method can play a good role in protection and aesthetics, when the soft silicone or the plug needs to be disassembled during equipment maintenance, it can only be pried open from the place where the soft silicone or the plug is fitted with the mounting hole 11, which makes it difficult to disassemble the soft silicone or the plug from the structural member, inconvenient for equipment installation and maintenance, and greatly increases the cost of equipment installation and maintenance.

[0037] In view of this, as Figures 2 to 6 shown, an embodiment of the present invention provides an equipment protection structure 100, and the equipment protection structure 100 includes:

[0038] A first structural member 10 and a second structural member 20. A mounting hole 11 is formed on the first structural member 10, and a first stepped guide chute 12 is formed on the inner peripheral surface of the mounting hole 11; the second structural member 20 is used to be installed in the mounting hole 11. A force application structure 22 is formed on the upper surface of the second structural member 20, and a second stepped guide chute 21 that cooperates with the first stepped guide chute 12 is formed on the outer peripheral surface of the second structural member 20, and the first stepped guide chute 12 is engaged with the second stepped guide chute 21 that cooperates with it. In this embodiment, the first structural member 10 is usually an equipment with a screw fastening structure, such as a PLC (Programmable Logic Controller) in industrial control equipment, an inverter, or an input / output module, etc.; the second structural member 20 is usually a circular plug or a protective cap for preventing foreign matters such as dust and water from the outside from entering; the force application structure 22 is usually a structure that can be acted on by a force application tool 30. For example, when the force application tool 30 is a screwdriver, the corresponding force application structure 22 is a groove for the screwdriver to act on.

[0039] In the technical solution adopted in this embodiment, a first stepped guiding chute 12 is formed on the inner peripheral surface of the mounting hole 11 on the first structural member 10, and a second stepped guiding chute 21 that cooperates with the first structural member 10 is formed on the outer peripheral surface of the second structural member 20. The first stepped guiding chute 12 is engaged with the second stepped guiding chute 21. At the same time, a force-applying structure 22 is formed on the upper surface of the second structural member 20. With such a setting, when it is necessary to remove the second structural member 20 from the first structural member 10 during equipment maintenance, a force-applying tool 30 can be placed in the force-applying structure 22 on the second structural member 20, and then the force-applying tool 30 is rotated. At this time, the mutually cooperating first stepped guiding chute 12 and second stepped guiding chute 21 will come into contact with each other and generate an outward thrust, prompting the first structural member 10 and the second structural member 20 to have relative movement, so that the second structural member 20 can be easily rotated out of the mounting hole 11 of the first structural member 10, greatly facilitating the installation and maintenance of the equipment, solving the problem of difficult disassembly in the prior art, reducing material damage during the disassembly process, greatly improving the ease of maintenance, and reducing the cost of equipment installation and maintenance.

[0040] It can be understood that when the second structural member 20 needs to be installed into the mounting hole 11 of the first structural member 10, the second structural member 20 is placed in the mounting hole 11 of the first structural member 10 and gently pressed. Under the interaction of the mutually cooperating first stepped guiding chute 12 and second stepped guiding chute 21, an inward thrust is generated, and the second structural member 20 can be smoothly installed into the first structural member 10. In this way, foreign matters such as dust and water from the outside are not easily introduced into the mounting hole 11, and thus are not easily introduced into the first structural member 10, improving the service life of the equipment. Moreover, the second structural member 20 covers the mounting hole 11, avoiding the exposure of the mounting hole 11 and making the equipment more beautiful.

[0041] In an embodiment of the present invention, as Figures 2 to 4 shown, the first stepped guiding chute 12 is a groove, and the second stepped guiding chute 21 is a protrusion. With such a setting, the concave-convex cooperation between the first stepped guiding chute 12 and the second stepped guiding chute 21 is realized through a groove and a protrusion, facilitating the relative movement between the first stepped guiding chute 12 and the second stepped guiding chute 21, and thus being conducive to generating an outward thrust when the first structural member 10 and the second structural member 20 are disassembled or an inward thrust when they are installed. It can be understood that the first stepped guiding chute 12 can also be a protrusion, and the second stepped guiding chute 21 can also be a groove, and the achieved effect is the same, which will not be elaborated here.

[0042] In an embodiment of the present invention, as Figure 4As shown, chamfers 23 are formed on at least one side of the second stepped guide chute 21. With such a setting, by providing chamfers 23 on one side of the second stepped guide chute 21, when the second structural member 20 is installed into the installation hole 11 of the first structural member 10, the chamfers 23 can play a good guiding role, facilitating the smooth installation of the second structural member 20 into the installation hole 11 of the first structural member 10 and making the installation process smoother.

[0043] In an embodiment of the present utility model, as Figures 3 to 4 shown, the number of the first stepped guide chutes 12 and the second stepped guide chutes 21 is at least two. Compared with only providing one first stepped guide chute 12 and one second stepped guide chute 21, providing at least two first stepped guide chutes 12 and second stepped guide chutes 21 can make it easier and more convenient for the second structural member 20 to rotate and withdraw from the installation hole 11 of the first structural member 10, further reducing the installation and maintenance costs. The specific number of the first stepped guide chutes 12 and the second stepped guide chutes 21 can be set as needed, and no limitation is made thereto, as long as it is convenient for the installation and disassembly of the first structural member 10 and the second structural member 20.

[0044] In an embodiment of the present utility model, as Figures 3 to 4 shown, the shapes of the first stepped guide chutes 12 and the second stepped guide chutes 21 can be any one of trapezoidal, circular, and spherical. Of course, in other embodiments, the shapes of the first stepped guide chutes 12 and the second stepped guide chutes 21 can be set as needed, and no limitation is made thereto.

[0045] In an embodiment of the present utility model, as Figures 4 to 5 shown, a limiting structure 24 is formed on the inner peripheral surface of the installation hole 11 of the first structural member 10 or the outer peripheral surface of the second structural member 20. Taking the limiting structure 24 being formed on the outer peripheral surface of the second structural member 20 as an example, a number of limiting structures 24 for interference and fixing are provided on the outer peripheral surface of the second structural member 20. When the second structural member 20 is installed into the installation hole 11 of the first structural member 10, first, the chamfers 23 will guide the second structural member 20 to be smoothly installed into the installation hole 11 of the first structural member 10, and then by gently pressing, the limiting structure 24 will interfere with the inner peripheral surface of the first structural member 10 and provide resistance, thereby fixing the second structural member 20 on the first structural member 10. It can be understood that when the limiting structure 24 is provided on the inner peripheral surface of the first structural member 10, the limiting structure 24 will interfere with the outer peripheral surface of the second structural member 20 and provide resistance to fix the second structural member 20 on the first structural member 10. With such a setting, the provision of the limiting structure 24 realizes the stable fixing of the second structural member 20 on the installation hole 11 of the first structural member 10, preventing the second structural member 20 from slipping out of the installation hole 11 of the first structural member 10.

[0046] In an embodiment of the present utility model, as Figures 4 to 5 shown, the limiting structure 24 is disposed on the outer peripheral surface of the second structural member 20 and is tangent to the outer peripheral surface of the second structural member 20. The thickness of the limiting structure 24 is gradually decreased from one end close to the upper surface of the second structural member 20 to the other end away from the upper surface of the second structural member 20. One end of the limiting structure 24 close to the upper surface of the second structural member 20 is thicker, and the other end away from the upper surface of the second structural member 20 is thinner. With such a setting, the thinner end of the limiting structure 24 can facilitate the second structural member 20 to smoothly enter the mounting hole 11 of the first structural member 10, and the thicker end of the limiting structure 24 can generate a greater interference resistance with the inner peripheral surface of the mounting hole 11 of the first structural member 10 to fix the second structural member 20 in the mounting hole 11 of the first structural member 10.

[0047] In an embodiment of the present utility model, as Figures 4 to 5 shown, the cross-sectional area of the limiting structure 24 is gradually decreased from one end close to the upper surface of the second structural member 20 to the other end away from the upper surface of the second structural member 20. One end of the limiting structure 24 close to the upper surface of the second structural member 20 is wider, and the other end away from the upper surface of the second structural member 20 is narrower. With such a setting, the narrower end of the limiting structure 24 can facilitate the second structural member 20 to smoothly enter the mounting hole 11 of the first structural member 10, and the wider end of the limiting structure can generate a greater interference resistance with the inner peripheral surface of the mounting hole 11 of the first structural member 10 to fix the second structural member 20 in the mounting hole 11 of the first structural member 10.

[0048] In an embodiment of the present utility model, as Figures 4 to 5 shown, the limiting structure 24 can be a rib position structure such as a small rib. The widths on both sides of the small rib are different, and the thicknesses are also different. Of course, in other embodiments, the limiting structure 24 can also be other structures for interference fixing, which is not limited herein.

[0049] In an embodiment of the present utility model, as Figure 6 shown, the shape of the force application structure 22 is a straight shape or a cross shape. When the second structural member 20 needs to be installed into the mounting hole 11 of the first structural member 10, a force application tool 30 can be placed in the straight-shaped or cross-shaped force application structure 22, and then the force application tool 30 is rotated to make the first structural member 10 and the second structural member 20 move relative to each other, so as to install the second structural member 20 into the mounting hole 11 of the first structural member 10 or remove the second structural member 20 from the mounting hole 11 of the first structural member 10. With such a setting, the straight-shaped or cross-shaped force application structure 22 provides a good force application point for the force application tool 30, facilitates the installation and disassembly of the second structural member 20, and reduces the installation and maintenance costs.

[0050] To achieve the above object, an embodiment of the present utility model provides an industrial control device, which includes the device protection structure of the above embodiment. Since this industrial control device adopts all the technical solutions of the above embodiment, it has at least all the beneficial effects brought by the technical solutions of the above embodiment, which will not be elaborated one by one here. In one embodiment, the industrial control device can be a PLC (Programmable Logic Controller), a frequency converter, an input / output module, etc., which is not limited herein.

[0051] The above is only an exemplary embodiment of the present utility model, and does not limit the patent scope of the present utility model. Any equivalent structural transformation made under the technical concept of the present utility model by using the content of the specification and drawings of the present utility model, or any direct / indirect application in other related technical fields is included in the patent protection scope of the present utility model.
