Description

Technical Field

[0001] The present invention relates to the technical field of electrical equipment installation, and in particular to a guide rail installation structure and a controller system. Background Art

[0002] The control unit of the industrial automation system is generally installed at the manufacturing site through the DIN (German Institute for Standardization) standard rail. The product unit is fixed on the DIN rail using the groove structure on the back of the product unit and a movable sliding buckle structure. When the sliding buckle is close to the center of the groove, the sliding buckle and the groove form a shape similar to the letter C, which is in a "locked" state, so that the product unit cannot fall out of the rail, and the product unit can be fixed and installed; when the sliding buckle is moved to a position away from the center of the groove, the original side of the letter C shape is opened, becoming an "open" state, so that the product unit can be removed from the rail.

[0003] When repairing, debugging, and replacing automation systems, it is often necessary to disassemble the control unit. Existing solutions require the use of tools, such as screwdrivers, to easily open the sliding buckle. When there are no suitable tools on site, it will affect the user's normal maintenance, debugging, and replacement work. The industry also has this demand and has proposed tool-free operation solutions, but these solutions require the cooperation of multiple parts to achieve tool-free locking and opening of the sliding buckle. Not only is the cost high and the production efficiency low, but the cooperation of multiple parts also reduces the reliability and service life of the system, and the requirements for the matching accuracy of the components become higher.

The unit body 10 is provided with a groove 101 for assembling the guide rail 20; the sliding buckle 30 is slidably arranged on the unit body 10, and a clamping portion 34 is arranged at one end of the sliding buckle 30 close to the groove 101; one of the guide groove 11 and the locking member 31 is arranged on the unit body 10, and the other is arranged on the sliding buckle 30, and the locking member 31 is slidably connected to the guide groove 11, and the guide groove 11 is provided with a starting position a and a locking position d, and the locking position d is located at the starting position a facing the groove 101; the elastic mechanism is arranged between the unit body 10 and the sliding buckle 30; wherein the sliding buckle 30 is used to move the locking member 31 from the starting position a to the locking position d under the action of an external force, so that the clamping portion 34 moves to the groove 101 to lock the guide rail 20; and is used to make the locking member 31 disengage from the locking position d under the action of an external force and return to the starting position a under the action of the elastic force provided by the elastic mechanism, so that the clamping portion 34 disengages from the groove 101 to release the guide rail 20.

[0046] Specifically, the guide rail installation structure can realize tool-free installation and removal between the product unit and the guide rail 20. Among them, the type of the product unit is not limited, for example, it can be a control unit of an industrial automation system or other functional module units. The guide rail 20 can be a DIN rail or a guide rail with a structure similar to the DIN rail. The guide rail 20 includes a U-shaped guide rail body and flanges respectively arranged on both sides of the width direction of the guide rail body, so that the cross-section of the guide rail 20 generally presents a "J"-shaped structure. The back of the unit body 10 of the product unit is provided with a groove 101 extending along the length direction of the guide rail 20, and the groove 101 can be used to accommodate the guide rail 20. The sliding buckle 30 can be slidably installed on the unit body 10 and is arranged adjacent to the groove 101. In order to facilitate the installation of the sliding buckle 30, optionally, the unit body 10 is also provided with a slide groove 102 for installing the sliding buckle 30, and the slide groove 102 extends along the width direction of the groove 101 and is connected to the groove 101. The sliding buckle 30 is installed in the slide groove 102, and the side wall of the slide groove 102 can also guide the sliding buckle 30. Optionally, the two side walls of the slide groove 102 are correspondingly provided with clamping grooves, and the opposite sides of the sliding buckle 30 are slidably arranged in the clamping grooves. The sliding buckle 30 can slide along the width direction of the groove 101 to approach or move away from the guide rail 20 in the groove 101. When the sliding buckle 30 moves toward the guide rail 20 to a position where the guide rail 20 is locked, the sliding buckle 30 is in a locked state, and in the locked state, the unit body 10 can be assembled with the guide rail 20; when the sliding buckle 30 moves away from the guide rail 20 to a position where the guide rail 20 is released, the sliding buckle 30 is in an open state, and in the open state, the unit body 10 can be removed from the guide rail 20.

[0047] The guide groove 11 and the locking member 31 cooperate to form a guide mechanism, and the locking member 31 can slide along the guide groove 11. The guide groove 11 can guide the locking member 31 to slide between the starting position a and the locking position d, thereby switching the sliding buckle 30 between the open state and the locked state. Figure 5 As shown, when the locking member 31 is in the starting position a, the sliding buckle 30 is in the open state, and the engaging portion 34 of the sliding buckle 30 is out of the groove 101 to release the guide rail 20; Figure 8As shown, when the locking member 31 is in the locking position d, the sliding buckle 30 is in a locked state, and the engaging portion 34 of the sliding buckle 30 moves into the groove 101 to lock the guide rail 20. One of the guide groove 11 and the locking member 31 is provided on the unit body 10, and the other is provided on the sliding buckle 30. For example, in this embodiment, the guide groove 11 is provided on the unit body 10, and the locking member 31 is provided on the sliding buckle 30. When the sliding buckle 30 moves relative to the unit body 10, the locking member 31 moves along the guide groove 11. Of course, in other embodiments, the positions of the guide groove 11 and the locking member 31 can also be interchanged, that is, the locking member 31 is provided on the unit body 10, and the guide groove 11 is provided on the sliding buckle 30. The guide groove 11 and the locking member 31 can be used as a part of the unit body 10 or the sliding buckle 30 respectively. In this way, there is no need to provide other independent components between the unit body 10 and the sliding buckle 30, which can reduce the number of overall components. The elastic mechanism is disposed between the unit body 10 and the sliding buckle 30, and the elastic mechanism is used to provide an elastic force (such as Figures 5 to 10 The elastic mechanism has a plurality of specific structures, such as an elastic member (such as a spring, a spring, etc.), or other mechanical matching structures capable of generating elastic deformation.

[0048] The technical solution of the present invention is to provide a guide groove 11, a locking member 31 and an elastic mechanism between the unit body 10 and the sliding buckle 30. When the sliding buckle 30 is in the open state, the locking member 31 is in the starting position a of the guide groove 11, and the guide rail 20 can be assembled into the groove 101 of the unit body 10; then a pressing force is applied to the sliding buckle 30 in the locking direction, and the locking member 31 can move from the starting position a to the locking position d along the guide groove 11. At this time, the pressing force on the sliding buckle 30 is cancelled, and the elastic force applied by the elastic mechanism can stably lock the locking member 31 at the locking position d, so that the sliding buckle 30 is kept in the locked state, thereby realizing the rapid assembly between the unit body 10 and the guide rail 20. When a pressing force in the locking direction is applied to the sliding buckle 30 again, the locking member 31 can be disengaged from the locking position d, and then under the elastic force applied by the elastic mechanism, the locking member 31 can move along the guide groove 11 to the starting position a, so that the sliding buckle 30 is switched from the locked state to the open state, thereby realizing the rapid disassembly between the unit body 10 and the guide rail 20. The technical solution of the present invention can reciprocate between the locking state and the open state by a simple pressing operation, thereby realizing the tool-free installation and disassembly between the unit body 10 and the guide rail 20, and the operation is simple and convenient; in addition, the guide groove 11 and the locking member 31 can be used as a part of the unit body 10 or the sliding buckle 30 respectively, so that the above functions can be realized without setting other independent components between the unit body 10 and the sliding buckle 30, the overall structure is simple, the components are streamlined, the cost can be effectively reduced, the production efficiency can be improved, and the reliability of the entire system can be guaranteed.

[0049] Please refer to Figures 2 to 4 In one embodiment, the guide groove 11 is an annular groove provided in the unit body 10, and the locking member 31 includes a rocker arm 311 connected to the sliding buckle 30, and a lock buckle 312 provided at the free end of the rocker arm 311, and the lock buckle 312 is inserted into the guide groove 11, and the rocker arm 311 is used to generate elastic deflection when the lock buckle 312 moves along the guide groove 11 to maintain the tendency of returning to the natural state.

[0050] In this embodiment, an annular guide groove 11 can be directly opened on the back of the unit body 10, and a locking member 31 can be integrally formed on the sliding buckle 30 to simplify the manufacturing process. The sliding buckle 30 can be made of POM (polyoxymethylene resin) material with good elasticity and wear resistance. Figure 4As shown, the sliding buckle 30 is provided with through holes penetrating both sides thereof in the thickness direction, the locking member 31 is provided in the through hole, and the locking member 31 includes a swing rod 311 and a lock 312. The swing rod 311 extends along the sliding direction of the sliding buckle 30, one end of the swing rod 311 is a connection end connected to the inner wall surface of the through hole, and the other end is a suspended free end, and the lock 312 extends from the free end of the swing rod 311 toward the unit body 10. When the sliding buckle 30 is installed on the unit body 10, the lock 312 is inserted into the guide groove 11. The swing rod 311 is a cantilever beam structure, and has a certain elastic deformation ability. When the sliding buckle 30 slides in a straight line relative to the unit body 10, the lock buckle 312 moves along the annular guide groove 11, and the side wall of the guide groove 11 will exert a certain amount of pressure on the lock buckle 312, so that the swing rod 311 can produce a certain elastic deflection, and at the same time, the swing rod 311 always maintains a tendency to return to the natural state, so that the lock buckle 312 can slide smoothly along the annular guide groove 11 to avoid jamming. Of course, in other embodiments, the elastic deflection and reset of the swing rod 311 can also be achieved by adding other components. For example, the connecting end of the swing rod 311 can be rotatably connected to the sliding buckle 30, and an elastic member is provided at the rotating connection.

[0051] Please refer to Fig.11 In one embodiment, the guide groove 11 includes a first guide segment 111, a locking segment 113 and a second guide segment 115 connected in sequence. The first guide segment 111 and the second guide segment 115 both extend obliquely relative to the sliding direction of the sliding buckle 30. The inlet end of the first guide segment 111 is connected to the outlet end of the second guide segment 115. The outlet end of the first guide segment 111 is connected to the inlet end of the second guide segment 115 via the locking segment 113. The inner ring wall of the guide groove 11 is provided with a locking groove 117 corresponding to the locking segment 113. The bottom of the locking groove 117 is lower than the outlet end of the first guide segment 111 and the inlet end of the second guide segment 115. The starting position a corresponds to the inlet end of the first guide segment 111. The locking groove 117 is provided with a locking position d.

[0052] In this embodiment, the first guide section 111, the locking section 113 and the second guide section 115 are connected end to end in sequence, so that the guide groove 11 generally presents an annular groove with a triangular structure. The first guide section 111 and the second guide section 115 are both inclined to extend relative to the sliding direction of the sliding buckle 30, and the extension direction of the locking section 113 is perpendicular or substantially perpendicular to the sliding direction of the sliding buckle 30. Figure 5As shown, when the sliding buckle 30 is in the open state, the lock buckle 312 is in the starting position a, and the swing rod 311 is in the natural state (no resilience), at which time the user can install the combination of the unit body 10 and the sliding buckle 30 on the guide rail 20 or remove it from the guide rail 20. The bottom of the locking groove 117 is lower than the outlet end of the first guide section 111 and the inlet end of the second guide section 115, and the locking groove 117 is provided with a locking position d, so that the locking position d is at a lower position than the outlet end of the first guide section 111 and the inlet end of the second guide section 115, so as to ensure that the lock buckle 312 can be kept in the locking position d when there is no external force.

[0053] For example, after the combination of the unit body 10 and the sliding buckle 30 is installed on the guide rail 20, the user applies a pressing force in the locking direction to the sliding buckle 30, and the sliding buckle 30 moves toward the locked state, and the lock buckle 312 of the locking member 31 moves from the starting position a along the first guide section 111 toward the locking position d. During the movement of the lock buckle 312, the swing rod 311 undergoes cantilever deformation to generate elastic deflection and gradually generates a rebound force to return to the natural state. When the lock buckle 312 moves to the corner position of the first guide section 111 and the locking section 113, it can no longer be pushed. At this time, the pressing force on the sliding buckle 30 is stopped. Under the action of the elastic force of the elastic mechanism and the rebound force of the swing rod 311, the lock buckle 312 can move to the locking position d, and the elastic mechanism applies an elastic force toward the open state to the sliding buckle 30, which can press the lock buckle 312 to the locking position d, so that the sliding buckle 30 remains in the locked state. When it is necessary to remove the unit body 10 from the guide rail 20, the user only needs to apply pressing force in the locking direction to the sliding buckle 30 again, and the locking member 31 will disengage from the locking position d and move to the entrance end of the second guide section 115 under the action of the rebound force of the rocker arm 311, and then move along the second guide section 115 under the action of the elastic mechanism, and finally move to the starting position a under the action of the rebound force of the rocker arm 311. At this time, the sliding buckle 30 and the guide rail 20 are loosened, and the user can remove the combination of the unit body 10 and the sliding buckle 30 from the guide rail 20.

[0054] In one embodiment, the connecting line direction of the starting position a and the locking position d is consistent with the extension direction of the swing rod 311 in the natural state. In this way, the lock buckle 312 is in the natural state (no rebound force) whether in the starting position a or the locking position d. In this way, even if the sliding buckle 30 is in the locked state or the open state for a long time, the swing rod 311 is not subjected to stress and is not easy to break, which can effectively improve the service life of the sliding buckle 30.

[0055] Furthermore, the extension direction of the swing rod 311 in the natural state is inclined at a preset angle toward the side close to the first guide section 111 relative to the sliding direction of the sliding buckle 30. In this way, when a pressing force in the locking direction is applied to the sliding buckle 30, an oblique force in the direction away from the first guide section 111 can be generated on the swing rod 311, thereby enabling the swing rod 311 to move toward the side away from the first guide section 111 to the entrance end of the second guide section 115.

[0056] In one embodiment, the outer annular wall of the guide groove 11 is provided with a first stop position b at the outlet end corresponding to the first guide section 111, a buffer position c is provided on the side of the locking groove 117 close to the inlet end of the locking section 113, a locking position d is formed on the side of the locking groove 117 close to the outlet end of the locking section 113, and the guide groove 11 also includes a sliding guide section 112 connected between the first stop position b and the buffer position c.

[0057] In this embodiment, Figures 5 to 8 As shown, when a pressing force is applied to the sliding buckle 30 in the open state, the lock buckle 312 moves from the starting position a along the first guide section 111 to the first stop position b. At this time, the outer ring wall of the guide groove 11 will stop the lock buckle 312, and the user can no longer push the sliding buckle 30. At this time, the user stops pressing the sliding buckle 30. Under the action of the elastic mechanism and the rebound action of the swing rod 311, the lock buckle 312 can move along the sliding guide section 112 to the buffer position c, and then under the rebound action of the swing rod 311, the lock buckle 312 moves from the buffer position c to the locking position d. The lock buckle 312 can be accurately guided to the buffer position c by the sliding guide section 112. In addition, during the process of the lock buckle 312 sliding from the buffer position c to the locking position d, the swing rod 311 can release a certain amount of elastic potential energy to prevent the lock buckle 312 from falling out of the locking position d due to excessive rebound force of the swing rod 311 at the locking position d. In order to make the lock buckle 312 slide into the buffer position c more easily and prevent the lock buckle 312 from easily falling out of the locking position d, the side wall height H1 of the locking groove 117 near the buffer position c is lower than the side wall height H2 of the locking groove 117 near the locking position d.

[0058] like Fig.11 and Fig.12As shown, in one embodiment, the outer ring wall of the guide groove 11 is provided with a second stop position e at the outlet end corresponding to the locking section 113, and the guide groove 11 also includes a slide-out guide section 114 connected between the locking position d and the second stop position e. Specifically, when a pressing force in the locking direction is applied to the sliding buckle 30 in the locked state, the lock buckle 312 can be guided from the locking position d to the second stop position e by the slide-out guide section 114 under the action of the rebound force of the swing rod 311. Due to the stopping effect of the outer ring wall of the guide groove 11, the user cannot continue to push the sliding buckle 30. At this time, the user stops pressing the sliding buckle 30, and the lock buckle 312 can slide into the second guide section 115 and move toward the starting position a under the action of the elastic mechanism. The lock buckle 312 can be guided by the slide-out guide section 114 so that the lock buckle 312 can smoothly escape from the locking position d and slide into the second guide section 115.

[0059] In one embodiment, the outer ring wall of the guide groove 11 is provided with a third stop position f corresponding to the outlet end of the second guide section 115, and the third stop position f is arranged side by side with the starting position a, and the guide groove 11 also includes a buffer section 116 connected between the third stop position f and the starting position a. Specifically, when the lock buckle 312 is released from the locking position d and slides to the second guide section 115, under the elastic force of the elastic mechanism, the lock buckle 312 slides toward the outlet end of the second guide section 115, during which the swing rod 311 undergoes cantilever deformation, generating a rebound force tending to a natural state, and after reaching the third stop position f, under the rebound force of the swing rod 311, the lock buckle 312 moves along the buffer section 116 to the starting position a, and the elastic potential energy of the swing rod 311 can be released through the buffer section 116, so that the swing rod 311 can finally return to a natural state.

[0060] The following combination Figures 5 to 10 as well as Fig.11 and Fig.12 , the specific movement process of the sliding buckle 30 of an embodiment is described in detail.

[0061] In one of the embodiments, the sliding direction of the sliding buckle 30 is taken as the first direction, and the direction intersecting with the first direction is taken as the second direction; wherein the second direction may intersect with the first direction perpendicularly, or the second direction may have a certain inclination angle with the first direction. For example, in this embodiment, the first direction is perpendicular to the second direction. The guide groove 11 is provided with a starting position a, a first stop position b, a buffer position c, a locking position d, a second stop position e and a third stop position f in sequence on the sliding path of the lock buckle 312; that is, the lock buckle 312 moves along the annular guide groove 11 in the order of starting position a-first stop position b-buffer position c-locking position d-second stop position e-third stop position f-starting position a. The first stop position b and the second stop position e are both located on the side of the locking position d away from the starting position a in the first direction, the first stop position b and the second stop position e are arranged side by side in the second direction, the buffer position c and the locking position d are arranged side by side in the second direction, and the third stop position f and the starting position a are arranged side by side in the second direction; a first guide section 111 is formed between the starting position a and the first stop position b, a sliding-in guide section 112 is formed between the first stop position b and the buffer position c, a locking section 113 is formed between the buffer position c and the locking position d, a sliding-out guide section 114 is formed between the locking position d and the second stop position e, a second guide section 115 is formed between the second stop position e and the third stop position f, and a buffer section 116 is formed between the third stop position f and the starting position a; the length of the first guide section 111 is greater than the length of the second guide section 115, and the lengths of the sliding-in guide section 112, the locking section 113 and the sliding-out guide section 114 are all less than the length of the second guide section 115.

[0062] like Figure 5 As shown, when the sliding buckle 30 is in the open state, the lock buckle 312 is in the starting position a, and the swing rod 311 is in a natural state without resilience; when a pressing force is applied to the sliding buckle 30 in the locking direction, as shown in FIG. Figure 6 As shown, the lock buckle 312 moves from the starting position a to the first stop position b along the first guide section 111. During this process, the swing rod 311 undergoes cantilever deformation, and cannot continue to push the sliding buckle 30 at the first stop position b, so it stops pushing. Figure 7 As shown, the lock buckle 312 moves to the buffer position c under the elastic force of the elastic mechanism and the rebound force of the swing rod 311; Figure 8 As shown, under the action of the rebound force of the swing rod 311, the lock buckle 312 moves from the buffer position c to the locking position d and is locked. At this time, the sliding buckle 30 is in a locked state; when a pressing force in the locking direction is applied to the sliding buckle 30 again, as shown in FIG. Fig. 9 As shown, the lock buckle 312 escapes from the locking position d under the rebound effect of the swing rod 311 and moves to the second stop position e. At the second stop position e, the sliding buckle 30 cannot be pushed further and is no longer pushed. Fig.10As shown, under the elastic force of the elastic mechanism, the lock buckle 312 moves from the second stop position e along the second guide section 115 to the third stop position f. During this process, the swing rod 311 undergoes cantilever deformation, and then the swing rod 311 drives the lock buckle 312 to move to the starting position a under the action of the rebound force, and the swing rod 311 returns to the natural state. That is, the user only needs to press twice to make the lock buckle 312 move along the guide groove 11 according to the closed loop path of starting position a-first stop position b-buffer position c-locking position d-second stop position e-third stop position f-starting position a, thereby realizing the switching of the sliding lock buckle 312 from the open state to the locked state, and then from the locked state to the open state. In the above process, the elastic force generated by the elastic mechanism is greater than the rebound force generated by the elastic deflection of the swing rod 311.

[0063] There are many specific structures of elastic mechanisms, such as Figure 3 As shown, in one embodiment, the elastic mechanism includes a limiting structure 12 and an elastic deformable member 32, one of the limiting structure 12 and the elastic deformable member 32 is arranged on the unit body 10, and the other is arranged on the sliding buckle 30, and the limiting structure 12 cooperates with the elastic deformable member 32 to provide an elastic force to move the locking member 31 toward the starting position a.

[0064] Specifically, in the present embodiment, the elastic deformable member 32 is provided on the sliding buckle 30, and the limiting structure 12 is provided on the unit body 10. When the sliding buckle 30 slides relative to the unit body 10, the limiting structure 12 generates a certain force on the elastic deformable member 32, so that the elastic deformable member 32 is elastically deformed, and then the elastic force is generated on the sliding buckle 30 to move toward the open state. Of course, in other embodiments, the positions of the limiting structure 12 and the elastic deformable member 32 can also be interchanged, that is, the elastic deformable member 32 is provided on the unit body 10, and the limiting structure 12 is provided on the sliding buckle 30. In addition, in other embodiments, an elastic member can also be directly provided between the sliding buckle 30 and the unit body 10 as an elastic mechanism. In the present embodiment, the limiting structure 12 and the elastic deformable member 32 can be respectively used as a part of the unit body 10 or the sliding buckle 30, so that there is no need to provide other independent components between the unit body 10 and the sliding buckle 30, which can further simplify the components.

[0065] Please refer to Figure 3 and Figure 4 In one embodiment, the limiting structure 12 is a limiting groove provided on the unit body 10, and the limiting groove has an extrusion surface opposite to the sliding buckle 30 and arranged at an angle, and the extrusion surface is arranged at an angle from one side close to the groove 101 toward the other side to gradually move away from the sliding buckle 30, and the elastic deformable member 32 includes an elastic arm 321 connected to the sliding buckle 30, and a convex buckle 322 provided at the free end of the elastic arm 321, and the convex buckle 322 is inserted into the limiting groove and can move along the extrusion surface.

[0066] Specifically, a limiting groove can be directly opened on the back of the unit body 10, and the elastic deformation member 32 can be integrally formed on the sliding buckle 30 to simplify the manufacturing process. Figure 4 As shown, the sliding buckle 30 is provided with through holes penetrating its two sides along the thickness direction, and the elastic deformation member 32 is provided in the through hole. The elastic deformation member 32 includes an elastic arm 321 and a convex buckle 322. The elastic arm 321 extends along the sliding direction of the sliding buckle 30. One end of the elastic arm 321 is a connection end connected to the inner wall surface of the through hole, and the other end is a suspended free end. The convex buckle 322 extends from the free end of the elastic arm 321 toward the unit body 10. When the sliding buckle 30 slides relative to the unit body 10, the convex buckle 322 can move along the extrusion surface. Since the extrusion surface is set as an inclined surface, the elastic arm 321 will be elastically deformed during the movement of the convex buckle 322, and then a force can be generated on the sliding buckle 30 toward the open state.

[0067] In addition, in actual applications, users can only judge whether the sliding buckle 30 is in a locked state or an open state based on experience from the tightness of the product installation and the position of the sliding buckle 30. There is no clear signal or mark in the related art to prompt the user of the installation status of the product. It is easy for the sliding buckle 30 to be unlocked. When it is unlocked, the product unit can also be hung on the guide rail 20, but it is easy for the unit to fall during the manufacturing process, causing the automation system to malfunction, resulting in production safety accidents and economic losses.

[0068] In order to enable users to understand the actual installation status of the product more intuitively and clearly, such as Figure 3 and Figure 4 As shown, in one embodiment, the end of the sliding buckle 30 away from the guide rail 20 is an identification end provided with a prompt mark 33; when the sliding buckle 30 is in an open state, the identification end extends out of the unit body 10 by a first length to display a first prompt information; when the sliding buckle 30 is in a locked state, the identification end extends out of the unit body 10 by a second length to display a second prompt information.

[0069] Specifically, when the sliding buckle 30 is in an open state, the identification end of the sliding buckle 30 extends out of the unit body 10 by a first length, and when the sliding buckle 30 is in a locked state, the identification end of the sliding buckle 30 extends out of the unit body 10 by a second length; the first length is generally greater than the second length, and due to the difference in length between the first length and the second length, the information displayed by the prompt mark 33 on the identification end that the user can see is also different, and thus the user can determine that the sliding buckle 30 is in an open state based on the first prompt information, and determine that the sliding buckle 30 is in a locked state based on the second prompt information. Among them, the prompt mark 33 on the identification end includes but is not limited to the use of text, numbers, shapes, patterns, colors, etc. For example, Figure 4 As shown, in this embodiment, the prompt mark 33 provided at the identification end is two letters "NOT" and "LOCK" arranged side by side along the sliding direction of the sliding buckle 30. When the sliding buckle 30 is in the open state, the identification end of the sliding buckle 30 extends out of the unit body 10 by a first length. At this time, the user can see the prompt message "NOT LOCK", and then it can be clearly seen that the sliding buckle 30 is in the open state. When the sliding buckle 30 is in the locked state, the identification end of the sliding buckle 30 extends out of the unit body 10 by a second length, and the second length is less than the first length. At this time, the user can see the prompt message "LOCK", and then it can be clearly seen that the sliding buckle 30 is in the locked state.

[0070] like Figure 1 As shown, in one embodiment, a sliding buckle 30 is provided on one side of the unit body 10 corresponding to the width direction of the groove 101, and a fixed buckle 13 is provided on the other side. When the guide rail 20 is assembled into the groove 101, one side of the guide rail 20 is limited by the fixed buckle 13, and the other side of the guide rail 20 is locked and limited by the sliding buckle 30, so that the guide rail 20 and the unit body 10 can be stably assembled. When disassembly is required, it is only necessary to press the sliding buckle 30 to move the sliding buckle 30 to the open state. It should be noted that the number of the fixed buckle 13 and the sliding buckle 30 is not limited. For example, one, two or more fixed buckles 13 can be arranged at intervals along the length direction on one side of the groove 101, and one, two or more sliding buckles 30 can be arranged at intervals along the length direction on the other side of the groove 101.

[0071] Of course, in other embodiments, the unit body 10 may be provided with sliding buckles 30 on both sides of the width direction of the groove 101. That is, the unit body 10 and the guide rail 20 are stably assembled by the cooperation of the sliding buckles 30 on both sides of the width direction of the groove 101. Similarly, the number of sliding buckles 30 on both sides of the groove 101 can be set according to actual needs, and can be one, two or more.

[0072] In one embodiment, the unit body 10 is provided with sliding buckles 30 on both sides of the groove 101 in the width direction, and the sliding buckles 30 on both sides of the groove 101 form a linkage match through a linkage mechanism. The linkage mechanism includes but is not limited to a mechanism that can realize power transmission, such as a connecting rod mechanism and a connecting rod slider mechanism. The sliding buckles 30 on both sides of the groove 101 are linked and connected through the linkage mechanism. In this way, only the sliding buckle 30 on one side needs to be operated, and the sliding buckle 30 on the other side can be driven to move synchronously through the linkage mechanism, which can improve the convenience of operation. For example, when the sliding buckle 30 on one side is pressed and locked, the sliding buckle 30 on the other side also moves to a locked state under the drive of the linkage mechanism; when the sliding buckle 30 on one side is pressed and opened, the sliding buckle 30 on the other side also moves to an open state under the drive of the linkage mechanism. And when the sliding buckles 30 on both sides are in the open state at the same time, the two sides of the guide rail 20 are not limited, and the unit body 10 can be more conveniently removed from the guide rail 20.

[0073] The present invention further provides a controller system, which includes a guide rail 20 and a plurality of control units, and the control units are mounted on the guide rail 20 through a guide rail mounting structure. The specific structure of the guide rail mounting structure refers to the above embodiment. Since the controller system 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 will not be described one by one here.

[0074] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
