Abstract
Description
Technical Field
[0001] This utility model relates to the field of switch chassis technology, specifically an industrial switch chassis. Background Technology
[0002] A switch is an intelligent network interconnection device used within a local area network (LAN) to filter and forward data frames based on MAC addresses. By isolating collision domains, providing dedicated bandwidth, and enabling full-duplex communication, it greatly improves the performance, security, and manageability of LANs. It is an indispensable key component of modern network infrastructure and can be used for electrical signal forwarding. Industrial switches, also known as industrial Ethernet switches, are Ethernet switching devices used in the industrial control field.
[0003] Industrial switch chassis serve as the "robust shell" and "mounting frame" for industrial switches. They are characterized by their robustness, reliability, and adaptability, protecting various internal electronic components. Typically, they consist of an outer shell with ventilation holes and various wiring holes. The outer shell generally comprises an upper protective cover and a lower base plate, secured together with bolts. Disassembly is possible by loosening screws for maintenance. Currently, during disassembly, the removed screws are usually placed elsewhere and reinstalled after repair. However, screws are typically small, and multiple screws need to be removed at once, making them prone to loss and causing inconvenience. Therefore, we offer industrial switch chassis to solve these problems. Utility Model Content
[0004] 1) Technical problems to be solved
[0005] This utility model proposes an industrial switch chassis that solves the problem that existing screws are usually small in size and require multiple screws to be removed at once, which makes the screws very easy to lose and causes inconvenience.
[0006] (ii) Technical Solution
[0007] To achieve the above objectives, this utility model provides the following technical solution: an industrial switch chassis, comprising a protective shell and a base plate at the bottom of the protective shell, wherein the protective shell has a plurality of wiring reserved holes and heat dissipation reserved holes, a fixing component is provided on the inner top wall of the protective shell, and a limiting component is provided on the upper surface of the base plate, the limiting component being located inside the fixing component and being able to slide inside the fixing component; a locking component is provided inside the limiting component, the limiting component being used to prevent the locking component from falling off the base plate; the upper end of the locking component is detachably connected to the fixing component, the locking component being used to fix the limiting component and the fixing component together.
[0008] Furthermore, the limiting component includes a cylinder, the lower end of which is fixedly connected to a base plate, and a limiting block is fixedly connected to the inner wall of the cylinder.
[0009] Furthermore, the fixing component includes a fixing cylinder, the upper surface of which is fixedly connected to the inner top wall of the protective shell, and the inner wall of which is slidably connected to the cylinder body.
[0010] Furthermore, the locking assembly includes a screwing block, a connecting rod fixedly connected to the upper surface of the screwing block, a locking block fixedly connected to the upper surface of the connecting rod, and a threaded rod fixedly connected to the upper surface of the locking block.
[0011] Furthermore, the outer surface of the twisting block is slidably connected to the cylinder, the outer surface of the connecting rod is slidably connected to the limiting block, the outer surface of the locking block is slidably connected to the cylinder, and the diameter of the locking block and the outer diameter of the limiting block are the same and both larger than the diameter of the connecting rod.
[0012] Furthermore, the inner wall of the upper end of the fixed cylinder is provided with a threaded groove, and the outer surface of the threaded rod is threadedly connected to the threaded groove.
[0013] Furthermore, a rubber base is slidably connected to the inner wall of the cylinder to support the entire structure.
[0014] (iii) Beneficial effects:
[0015] Compared with existing technologies, this industrial switch chassis has the following advantages:
[0016] I. This industrial switch chassis incorporates locking and limiting components. After the locking component is disassembled, the limiting component keeps it in place, preventing separation between the locking and limiting components. This avoids the locking component from separating from the base plate, eliminating the need for separate storage like traditional screws. This fundamentally prevents maintenance delays or additional procurement costs caused by the loss of small fasteners, effectively preventing the loss of the locking component. It also solves the problem that existing screws are typically small and require multiple removals at once, making them prone to loss and causing inconvenience.
[0017] Second, the industrial switch chassis, through the setting of fixed components and other parts, forms a threaded connection between the threaded rod and the threaded groove on the inner wall of the upper end of the fixed cylinder. As it rotates in the forward direction, the threaded rod gradually screws into the depth of the threaded groove until the lower surface of the clamping block tightly presses against the upper end face of the cylinder. Thus, through the fixed relationship between the fixed cylinder and the protective shell, and the fixed relationship between the cylinder and the base plate, a firm connection between the protective shell and the base plate is achieved, ensuring the stable operation of the equipment in the industrial environment.

Detailed Implementation
[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] like Figure 1-5As shown, this utility model provides a technical solution: an industrial switch chassis, including a protective shell 1 and a base plate 2 at the bottom of the protective shell 1. The protective shell 1 has several wiring reserved holes 6 and heat dissipation reserved holes 7. A fixing component 3 is provided on the inner top wall of the protective shell 1. A limiting component 4 is provided on the upper surface of the base plate 2. The limiting component 4 is located inside the fixing component 3 and can slide inside the fixing component 3. A locking component 5 is provided inside the limiting component 4. The limiting component 4 is used to prevent the locking component 5 from falling off the base plate 2. The upper end of the locking component 5 is detachably connected to the fixing component 3. The locking component 5 is used to fix the limiting component 4 and the fixing component 3 together. During normal use, the locking component 5 can be used to fix the limiting component 4 together with the fixing component 3. Component 5 connects and fixes the limiting component 4 and the fixing component 3 together, preventing slippage between them and thus fixing the protective shell 1 and the base plate 2 together for stable use. After the locking component 5 is disassembled, the limiting component 4 limits the locking component 5 to prevent it from separating from the limiting component 4, thereby preventing the locking component 5 from separating from the base plate 2. Compared with the existing screw separation method, the locking component 5 is always located on the base plate 2 and will not be lost, achieving the effect of preventing the locking component 5 from being lost. The protective shell 1 and the base plate 2 are made of SUS304 stainless steel, which has excellent corrosion resistance to adapt to industrial environments.
[0027] The limiting component 4 includes a cylindrical body 401, the lower end of which is fixedly connected to the base plate 2. A limiting block 402 is fixedly connected to the inner wall of the cylindrical body 401. There are two cylindrical bodies 401, which are combined to form an integral cylinder. There are also two limiting blocks 402, which are combined to form an annular block. The two limiting blocks 402 are fixed to the inner sides of two different cylindrical bodies 401. During production, the internal locking component 5 needs to be placed between the two cylindrical bodies 401 first, and then the two cylindrical bodies 401 are combined and welded to fix them so as to restrict the locking component 5 inside. The fixing cylinder 301 and the cylindrical body 401 are made of 6061 aluminum alloy and are anodized.
[0028] The fixing component 3 includes a fixing cylinder 301, the upper surface of which is fixedly connected to the inner top wall of the protective shell 1, and the inner wall of the fixing cylinder 301 is slidably connected to the cylinder body 401. The locking component 5 includes a screwing block 501, a connecting rod 502 is fixedly connected to the upper surface of the screwing block 501, a locking block 503 is fixedly connected to the upper surface of the connecting rod 502, and a threaded rod 504 is fixedly connected to the upper surface of the locking block 503. The inner wall of the screwing block 501 is provided with a cross groove to facilitate tightening or loosening using a Phillips screwdriver.
[0029] The outer surface of the rotating block 501 is slidably connected to the cylinder 401, the outer surface of the connecting rod 502 is slidably connected to the limiting block 402, and the outer surface of the locking block 503 is slidably connected to the cylinder 401. The diameter of the locking block 503 is the same as the outer diameter of the limiting block 402, both of which are larger than the diameter of the connecting rod 502. After disassembly, the locking component 5 moves downward as a whole, and the locking component 5 is blocked by the limiting block 402 to prevent the locking component 5 from coming off the inside of the cylinder 401. This ensures that the locking component 5 is always on the bottom plate 2 and does not need to be moved to another position, thus preventing the loss of the locking component 5.
[0030] The upper inner wall of the fixed cylinder 301 has a threaded groove 302. The outer surface of the threaded rod 504 is threadedly connected to the threaded groove 302. By rotating the screwing block 501, the locking assembly 5 can be rotated as a whole, including the uppermost threaded rod 504, thereby realizing the rotation of the threaded rod 504 inside the threaded groove 302. When rotating in the forward direction, the threaded rod 504 is inserted deep into the threaded groove 302, and the upper end of the cylinder 401 is pressed by the locking block 503 to fix the cylinder 401 to the fixed cylinder 301. When rotating in the reverse direction, the threaded rod 504 is driven to disengage from the inside of the threaded groove 302, thereby realizing the separation of the cylinder 401 from the fixed cylinder 301, so as to disassemble the protective shell 1 and the base plate 2.
[0031] A rubber base 8 is slidably connected to the inner wall of the cylinder 401 to support the whole. The rubber base 8 makes it easy to place the switch on the platform and seal the screw block 501. Firstly, it prevents dust from entering, and secondly, it increases the aesthetics of the bottom. The rubber base 8 can be pulled out directly from the bottom of the cylinder 401.
[0032] Working principle: During production, the locking component 5 is first placed between the two cylinders 401, and then the two cylinders 401 are welded together to form a complete cylinder. At the same time, the two limiting blocks 402 on the inner side are simultaneously merged into an annular block. The locking component 5 is restricted inside the cylinder 401 and can only slide along the axis of the cylinder 401. It cannot be dislodged laterally, which lays the foundation for subsequent anti-loss.
[0033] During installation, insert a Phillips screwdriver into the Phillips groove of the tightening block 501 and rotate the block 501 clockwise to rotate the connecting rod 502, the locking block 503 and the threaded rod 504 fixed thereto. The threaded rod 504 forms a threaded connection with the threaded groove 302 on the inner wall of the upper end of the fixed cylinder 301. As the clockwise rotation occurs, the threaded rod 504 gradually screws into the depth of the threaded groove 302 until the lower surface of the locking block 503 tightly presses against the upper end face of the cylinder 401.
[0034] The squeezing action of the clamping block 503 eliminates the relative sliding gap between the cylinder 401 and the fixed cylinder 301. Thus, through the fixed relationship between the fixed cylinder 301 and the protective shell 1, and the fixed relationship between the cylinder 401 and the base plate 2, a firm connection between the protective shell 1 and the base plate 2 is achieved, ensuring stable operation of the equipment in the industrial environment. At the same time, the wiring reserved hole 6 can be used to connect cables normally, and the heat dissipation reserved hole 7 can be used to dissipate heat from the internal components. A dustproof net can be pasted on the inside of the heat dissipation reserved hole 7 to increase the dustproof effect.
[0035] When it is necessary to disassemble the protective shell 1 for internal maintenance, use a Phillips screwdriver to rotate the block 501 in the opposite direction, causing the threaded rod 504 to rotate in the opposite direction simultaneously. This causes the threaded rod 504 to gradually disengage from the threaded groove 302 of the fixed cylinder 301 until the threaded rod 504 is completely disengaged from the threaded groove 302. At this time, the locking state of the fixed component 3 and the limiting component 4 is released. After the lock is released, lift the protective shell 1 upwards. The fixed cylinder 301 will disengage from the cylinder 401 simultaneously with the protective shell 1. At the same time, the locking component 5, having lost the support of the threaded groove 302, slides downwards along the inner wall of the cylinder 401 under the action of gravity. Since the diameter of the locking block 503 is the same as the outer diameter of the limiting block 402 and both are larger than the diameter of the connecting rod 502, when the locking block 503 slides to the upper surface of the limiting block 402, it will be blocked by the limiting block 402 and cannot continue to slide downwards, thus preventing the locking component 5 from disengaging from the inside of the cylinder 401.
[0036] After the maintenance is completed, there is no need to find additional fasteners. Simply fasten the protective shell 1 onto the base plate 2, so that the cylinder 401 slides back into the fixed cylinder 301. Then, rotate the screw block 501 in the forward direction to complete the locking. Throughout the process, the locking component 5 remains connected to the base plate 2, which completely solves the problem of traditional screws being easily lost after disassembly.
