Description

Technical Field

[0001] This utility model belongs to the technical field of analog input modules, and specifically relates to an analog input module mounting bracket. Background Technology

[0002] An analog input module mounting bracket is a mechanical structure used to install and secure analog input modules in industrial automation control systems. These modules are typically used to acquire continuously changing analog signals such as temperature, pressure, and flow rate, and convert them into digital signals for processing by the control system. As a supporting accessory, the mounting bracket must be designed to match the module's dimensions, installation interface, and operating environment requirements.

[0003] In the prior art, such as the analog input acquisition module device disclosed in patent publication number CN209546164U, an integrated circuit board is provided inside the housing. The integrated circuit board includes a sensor module, an AD sampling module, a signal switching circuit, a signal adjustment circuit, and a controller connected in sequence. The sensor module includes a voltage sensor and a current sensor, and the AD sampling module includes multiple AD sampling channels. Multiple terminals are provided outside the housing, and each terminal is connected to a module on the integrated circuit board. However, in practical applications, when the analog input module body is placed in the mounting frame, there is a lack of effective reinforcement devices, which is not conducive to reinforcing the placed analog input module. When vibrations occur during equipment operation or when it is subjected to external collisions, the analog input module body is prone to movement, which affects the signal acquisition accuracy of the analog input module and the stability of system operation, and may even lead to module damage.

[0023] 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.

[0024] Example 1

[0025] Please see Figures 1-5 This is the first embodiment of the present invention, which provides an analog input module mounting bracket, including...

[0026] The fixed frame body 1 has an analog input module body 2 inside the fixed frame body 1. The core components of the fixed frame and the relationship between the two are clearly defined. The disassembly and assembly setting makes it easy to install and replace the analog input module body 2. When the module fails or needs to be upgraded, it can be quickly disassembled, repaired and replaced, reducing maintenance costs and downtime, and improving the flexibility and convenience of equipment use.

[0027] The reinforcement device includes a reinforcement plate 4 rotatably mounted on the fixed frame body 1. The reinforcement plate 4 can rotate to ensure the placement and removal of the analog input module body 2. A limiting block 41 is set at the bottom of the reinforcement plate 4, which realizes the addition of the limiting block 41. A baffle 6 is installed on the front surface of the analog input module body 2 by screws to increase the stability of the baffle 6 installation. A slot 61 is opened on the top of the baffle 6 for the limiting block 41 to be inserted. A baffle 7 is set on the inner side of the slot 61. When the limiting block 41 is inserted into the slot 61, the limiting block 41 abuts against the baffle 7. By rotating the reinforcement plate 4, the limiting block 41 is inserted into the slot 61 and abuts against the baffle 7, forming a mechanical limiting structure. The analog input module body 2 is reinforced from the front, effectively preventing the module from moving in the front-back direction within the fixed frame. The structure is simple and stable. Compared with complex reinforcement methods, it is lower in cost and more reliable. At the same time, it is easy to operate and facilitates quick installation and removal of the module.

[0028] In this embodiment, preferably, it also includes a threaded hole 42 opened inside the reinforcing plate 4, realizing the opening of the threaded hole 42. A threaded rod 5 is threadedly connected to the threaded hole 42, and a threaded groove 23 is opened on the analog input module body 2 and threadedly connected to the threaded rod 5. The threaded rod 5 cooperates with the threaded hole 42 and the threaded groove 23. After the reinforcing plate 4 is initially limited by the limiting block 41, the reinforcing plate 4 is further fastened to the analog input module body 2, providing additional fixing force from above, enhancing the firmness of the module fixation, preventing the module from loosening or detaching upward under vibration or other conditions, and improving the stability and reliability of the overall structure.

[0029] In this embodiment, preferably, the limiting block 41 and the reinforcing plate 4 are an integral structure, which reduces the number of component connections, enhances the structural strength, and avoids the reinforcement effect being affected by loose connections. The rear surface of the reinforcing plate 4 is provided with a fixing shaft 8, and the analog input module body 2 is provided with a rotating hole for the fixing shaft 8 to rotate. The fixing shaft 8 cooperates with the rotating hole, making the rotation process of the reinforcing plate 4 smoother and more stable, facilitating quick reinforcement and disassembly operations of the module, and improving the efficiency of use.

[0030] In this embodiment, preferably, an extension strip 22 is also provided at the bottom of the analog input module body 2, which realizes the addition of the extension strip 22. A sliding groove 12 is opened in the bottom of the fixing frame body 1 for the extension strip 22 to be inserted. The extension strip 22 cooperates with the sliding groove 12 to guide and limit the analog input module body 2 from the bottom. This not only makes it convenient for the module to be accurately installed into the fixing frame body 1, but also prevents the module from moving in the left and right and up and down directions in the fixing frame. It cooperates with the reinforcing plate 4 and other structures to achieve multi-directional fixation of the module and further improve the stability of the module installation.

[0031] In this embodiment, preferably, the side surface of the analog input module body 2 is provided with heat dissipation holes 21, and the side surface of the fixing bracket body 1 is provided with an opening 11. The heat dissipation holes 21 and the opening 11 cooperate to form a heat dissipation channel, which accelerates the dissipation of heat generated during the operation of the analog input module body 2, effectively reduces the module temperature, avoids the module performance degradation or damage due to excessive temperature, extends the module service life, and ensures stable system operation.

[0032] Example 2

[0033] Please see Figures 1-6 This is the second embodiment of the present invention, which is based on the previous embodiment, but differs in that:

[0034] A dustproof mesh 3 is installed on the inner side of the opening 11. The dustproof mesh 3 can prevent dust and debris from entering the interior of the mounting bracket body 1 through the opening 11, avoiding dust accumulation that affects the heat dissipation and normal operation of the module and protecting the module performance. A fastening plate 9 is installed on the inner side of the mounting bracket body 1. The fastening plate 9 has a cuboid structure. The rear surface of the analog input module body 2 abuts against the fastening plate 9. The cuboid structure of the fastening plate 9 has a large contact area, which can evenly apply the abutment force to the analog input module body 2 and avoid excessive local force that could damage the module.

[0035] The working principle and usage process of this utility model are as follows: Align the extension strip 22 at the bottom of the analog input module body 2 with the slide groove 12 at the bottom of the fixed frame body 1, and slowly push the module along the slide groove 12 so that the module can slide smoothly into the fixed frame body 1. The initial positioning and guidance are achieved through the cooperation of the extension strip 22 and the slide groove 12.

[0036] Continue pushing the module until the rear surface of the analog input module body 2 abuts against the fastening plate 9. At this time, the module is initially limited in the front-back direction, and the fastening plate 9 abuts against the rear surface of the module evenly to avoid excessive local force.

[0037] Rotate the reinforcing plate 4 downwards with the fixed shaft 8 as the axis, so that the limiting block 41 at the bottom of the reinforcing plate 4 is aligned with the slot 61 at the top of the baffle 6; insert the limiting block 41 into the slot 61 until the limiting block 41 abuts against the baffle 7 on the inner side of the slot 61. At this time, the analog input module body 2 is initially reinforced from the front to prevent the module from moving in the front-back direction.

[0038] The threaded rod 5 is passed through the threaded hole 42 inside the reinforcing plate 4 and then screwed into the corresponding threaded groove 23 on the analog input module body 2. Through the threaded connection between the threaded rod 5 and the threaded hole 42 and the threaded groove 23, the reinforcing plate 4 and the analog input module body 2 are further fastened together, providing additional fixing force from above and enhancing the module's fixation.

[0039] During the operation of the analog input module body 2, the heat generated by it is discharged through the heat dissipation holes 21 on the side surface and the opening 11 on the side surface of the mounting frame body 1. The dustproof net 3 can prevent dust and debris from entering the mounting frame, ensuring good heat dissipation and normal operation of the module.

[0040] Regularly check whether the connections of each component of the fixing frame are loose, such as whether the threaded rod 5 is tightened, whether the reinforcing plate 4 rotates flexibly, and whether the dust screen 3 is blocked. If any problems are found, deal with them in time to ensure the stable operation of the system.

[0041] First, unscrew the threaded rod 5 to separate it from the threaded hole 42 and the threaded groove 23, and release the upper fastening connection between the reinforcing plate 4 and the analog input module body 2;

[0042] Rotate the reinforcing plate 4 upwards to disengage the limiting block 41 from the slot 61, thereby releasing the restriction on the module from the front direction;

[0043] Hold the analog input module body 2 and slowly pull it out from inside the mounting bracket body 1 along the slide 12 to complete the module disassembly for maintenance, upgrade or replacement.

[0044] Although embodiments of the present invention have been shown and described in detail above, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
