Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of industrial control equipment installation, in particular to a module installation structure and industrial control equipment. Background Art
[0002] IO modules (input / output modules) play an important role in automation control systems. They are responsible for transmitting signals from field devices (such as sensors, actuators, etc.) to control systems (such as PLCs, industrial PCs, etc.), and transmitting control system instructions to field devices. IO modules generally need to be installed on the rail through a module mounting seat for installing electrical modules to facilitate system layout and maintenance.
[0003] In the related art, the module mounting seat usually adopts a snap-on assembly to achieve a detachable connection with the guide rail. Specifically, a movable snap-on is formed on the back of the module mounting seat. When fixed, the movable snap-on locks the guide rail so that the module mounting seat cannot fall off the guide rail. When disassembling, the module mounting seat is pushed hard in the direction of the movable snap-on so that one side of the module mounting seat is first detached from the guide rail, and then the module mounting seat is rotated to detach the other side of the module mounting seat from the guide rail.
[0004] The above scheme establishes a reliable connection between the module mounting seat and the guide rail through the movable buckle. However, in order to ensure the stable position of the module mounting seat, the side wall of the module mounting seat facing the guide rail is usually arranged in close contact with the mounting surface of the guide rail. This will make it easy for the staff to interfere with the guide rail during the rotation process when performing the disassembly operation, resulting in limited operating space and difficult disassembly.

[0034] The utility model provides a module installation structure 100 .
[0035] See also Figures 1 to 4 In one embodiment of the utility model, the module mounting structure 100 includes a guide rail 1, a mounting seat 2 and a cushion block 3, a first mounting surface 11 is formed on one side of the guide rail 1; the mounting seat 2 is clamped on the guide rail 1, and the mounting seat 2 has a second mounting surface 23 facing the first mounting surface 11; the cushion block 3 is arranged on the mounting seat 2 or the guide rail 1, and the cushion block 3 has a first side wall and a second side wall arranged opposite to each other in a first direction, the first side wall abuts against the first mounting surface 11, and the second side wall abuts against the second mounting surface 23.
[0036] The module mounting structure 100 provided by the utility model forms a gap between the mounting seat 2 and the guide rail 1 by adding a cushion block 3 between the mounting seat 2 and the guide rail 1, thereby providing an escape space for the rotation of the mounting seat 2 during the disassembly process of the mounting seat 2, so that the mounting seat 2 can be smoothly disassembled from the guide rail 1, thereby improving the ease of disassembly of the entire module and facilitating maintenance and replacement by users. In addition, the design of the cushion block 3 can effectively reduce the direct contact between the mounting seat 2 and the guide rail 1, thereby reducing the risk of wear caused by friction during the disassembly process, helping to extend the service life of the mounting seat 2 and the guide rail 1, and reducing failures caused by wear.
[0037] It should be noted that the pad 3 can be arranged on the mounting seat 2 or on the guide rail 1, as long as the distance between the guide rail 1 and the mounting seat 2 can be increased, and its fixing method can be achieved through a snap-on structure 4 or a screw locking structure; and in one embodiment of the present application, the pad 3 is fixed on the mounting seat 2.
[0038] Furthermore, in one embodiment of the present application, the cross-sectional area of the cushion block 3 is gradually reduced from one end close to the mounting seat 2 to one end away from the mounting seat 2. The mounting seat 2 can rotate with one edge or one point of the first side wall of the cushion block 3 as support during the rotation process. Since the cross-sectional area of the cushion block 3 is gradually reduced from one end close to the mounting seat 2 to one end away from the mounting seat 2, it is possible to avoid interference between the cushion block 3 and the guide rail 1 during rotation, thereby further ensuring smooth rotation of the mounting seat 2.
[0039] It can be known that the pad 3 of the trapezoidal structure or the pad 3 of the truncated cone structure can provide an avoidance space for rotation, but considering that the pad 3 of the truncated cone structure is in point-to-surface contact with the guide rail 1 during the rotation of the mounting seat 2, this will result in only one contact point between the pad 3 and the guide rail 1, which may cause instability during the rotation process. Therefore, in one embodiment of the present application, the cross-section of the pad 3 is a trapezoidal structure, that is, the pad 3 is a trapezoidal boss, so that when the pad 3 rotates with the mounting seat 2, one side of the first side wall of the pad 3 can form a continuous contact line with the first mounting surface 11 of the guide rail 1. This contact method can provide a larger contact area than point-to-surface contact, thereby dispersing the pressure, reducing the risk of wear and deformation of the pad 3 and the guide rail 1, and improving the service life.
[0040] In one embodiment of the present application, the cushion block 3 and the mounting seat 2 are an integrally formed structure. The integrally formed structure ensures the geometric and performance consistency between the cushion block 3 and the mounting seat 2, reduces the performance difference caused by assembly errors, thereby reducing possible stress concentration points and improving the strength and durability of the structure. The integral forming method can be selected according to the different materials of the mounting seat 2, such as plastic injection molding or metal die casting.
[0041] In one embodiment of the present application, the module mounting structure 100 further includes a snap structure 4, which includes a first clamping arm 41 and a second clamping arm 42 arranged at intervals on the mounting seat 2 along the second direction, and a clamping space for clamping the guide rail 1 is formed between the first clamping arm 41 and the second clamping arm 42; wherein the first direction and the second direction are arranged vertically, and at least one of the first clamping arm 41 and the second clamping arm is an elastic arm. The design of the snap structure 4 enables the mounting seat 2 to firmly clamp the guide rail 1 during the installation and removal process, thereby improving the stability of the structure. Specifically, during installation, the bayonet formed by the first clamping arm 41 and the second clamping arm 42 is first clamped on the guide rail 1, and then the elastic arm is pressed hard, so that the mounting seat 2 can be stably installed on the guide rail 1. During disassembly, the mounting seat 2 is grasped and pushed hard in the movable direction of the elastic arm, so that one end of the mounting seat 2 can be separated from the guide rail 1 first. Of course, in other embodiments of the present application, an active snap structure 4 with a spring assembly can also be used to replace the clamping method of setting the elastic arm.
[0042] Usually, the guide rail 1 needs to be installed on a rack or a cabinet. Therefore, in order to prevent the mounting base 2 from interfering with the rack or the cabinet during rotation and affecting the disassembly and assembly efficiency, in one embodiment of the present application, the first clamping arm 41 is an elastic arm; the mounting base 2 includes a mounting section 21 and an avoidance section 22 connected in sequence in the second direction, and the mounting section 21 is provided with a first clamping arm 41 and a second clamping arm 42. The cross-sectional area of the avoidance section 22 is gradually reduced from close to the first clamping arm 41 toward a direction away from the first clamping arm 41. In this way, sufficient avoidance space can be provided to prevent the mounting base 2 from directly contacting the rack or the cabinet during rotation, thereby ensuring smooth rotation of the mounting base 2 and improving disassembly and assembly efficiency.
[0043] In one embodiment of the present application, the first clamping arm 41 has a first end and a second end in the first direction, the first end of the first clamping arm 41 is connected to the mounting seat 2, the second end of the first clamping arm 41 is swingably arranged in the second direction, and the second end of the first clamping arm 41 is spaced apart from the mounting seat 2, and a clamping protrusion is formed at the second end of the first clamping arm 41; the second clamping arm 42 has a first end and a second end in the second direction, the first end of the second clamping arm 42 is connected to the mounting seat 2, the second end of the second clamping arm 42 is arranged toward the first clamping arm 41, and the second clamping arm 42 and the clamping protrusion limit the guide rail 1 in the first direction. The second end of the first clamping arm 41 is formed with a clamping protrusion, which helps to provide better grip and stability when clamping the guide rail 1, ensuring that the guide rail 1 does not slide or move during installation.
[0044] In one embodiment of the present application, the second mounting surface 23 is concavely provided with a positioning groove 24, and the groove wall of the positioning groove 24 facing the first mounting surface 11 forms the second mounting surface 23; the guide rail 1 is inserted into the positioning groove 24 from the notch of the positioning groove 24. The design of the positioning groove 24 can ensure that the mounting seat 2 can be accurately positioned on the guide rail 1 during installation, reducing equipment failure or performance degradation caused by inaccurate installation, and because the guide rail 1 can be inserted into the positioning groove 24 from the notch of the positioning groove 24, the alignment process of the mounting seat 2 can also be simplified, reducing the installation steps and improving the installation efficiency.
[0045] The utility model also provides an industrial control device, which includes a module installation structure 100. The specific structure of the module installation structure 100 refers to the above embodiment. Since the industrial control device adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which are not described one by one here.
