Description

Technical Field

[0001] This application relates to the field of industrial control technology, and in particular to a guide rail hook and electronic device. Background Technology

[0002] Currently, in the field of industrial control, guide rails are typically engaged with guide rail hooks on electronic devices to allow the guide rails to be installed on the electronic devices, and other modules are installed on the guide rails to achieve physical connection between the electronic devices and various modules.

[0003] In related technologies, guide rail hooks are typically detachable hooks, meaning they are assembled from multiple separate parts. These parts are hinged together. When the guide rail needs to be removed from the hook, pressing or pulling one part will trigger the hinged parts, causing the hook to open.

[0004] However, the hinge gaps between the multiple parts of the guide rail hook can cause errors in the travel transmission of the guide rail hook, and the high structural complexity of the guide rail hook results in high production costs. Utility Model Content

[0005] The purpose of this application is to provide a guide rail hook and an electronic device to simplify the structure of the guide rail hook, reduce errors in stroke transmission, and lower production costs. The specific technical solution is as follows:

[0006] This application provides a guide rail hook, including: a connecting part, a spring arm, a first locking part, and a second locking part;

[0009] The second snap-fit ​​portion is fixedly connected to the second end of the connecting portion, located on the side corresponding to the position of the first snap-fit ​​portion, and spaced apart from the first snap-fit ​​portion;

[0010] After the external force is removed, the first locking part is reset, and the width of the mounting area between the first locking part and the second locking part after the first locking part is reset is not greater than the width of the guide rail.

[0011] In some embodiments of this application, the guide rail hook further includes: a guide portion;

[0012] The first end of the guide portion is fixedly connected to the second end of the connecting portion, and the other end extends in a direction away from the elastic arm;

[0013] The electronic device housing on which the guide rail hook is mounted has a hook blocking part, which is located between the first end and the second end of the connecting part and abuts against the elastic arm.

[0014] When a pulling force opposite to the first direction of the elastic arm is applied to the second end of the guide portion, the guide portion drives the connecting portion and the elastic arm to move in the first direction. The elastic arm is blocked by the hook blocking portion, causing the moving end to drive the first locking portion to move in the opposite direction of the first direction, so as to increase the distance between the first locking portion and the second locking portion.

[0015] In some embodiments of this application, the connecting part includes: a main trunk and a fixed frame that are connected to each other, and the main trunk has a through swing arm opening;

[0016] The fixed frame includes: a top beam and side walls located at both ends of the top beam; the elastic arm is located between the two side walls; the fixed end of the elastic arm is fixedly connected to the top beam; and the movable end of the elastic arm passes through the swing arm opening.

[0017] In some embodiments of this application, a feedback block is provided on the guide portion; the feedback block is used to cooperate with the feedback groove of the device housing of the electronic device on which the guide rail hook is installed, and can provide tactile feedback to the user when the feedback block is inserted into or removed from the feedback groove to indicate that it has been moved into place.

[0018] In some embodiments of this application, a positioning guide groove is provided on the side wall of the connecting part and / or the guide part for cooperating with the positioning slider of the device housing of the electronic device on which the guide rail hook is installed, and the positioning slider is slidably embedded in the positioning guide groove.

[0019] In some embodiments of this application, the first latching portion has a guide surface facing the second latching portion;

[0020] And / or,

[0021] The second snap-fit ​​portion has a guide surface facing the first snap-fit ​​portion.

[0022] This application also provides an electronic device, including: a device housing and a guide rail hook of any of the above embodiments;

[0023] The device housing is provided with a hook mounting groove; the guide rail hook is slidably mounted in the hook mounting groove.

[0024] In some embodiments of this application, the hook mounting groove includes a hook blocking portion; the hook blocking portion is located between the first end and the second end of the connecting portion; the hook blocking portion is used to abut against the elastic arm.

[0025] In some embodiments of this application, when a guide portion is present on the guide rail hook, a feedback block is provided on the guide portion;

[0026] The hook mounting slot includes a feedback slot.

[0027] In some embodiments of this application, when a guide portion is present on the guide rail hook, positioning guide grooves are provided on the sidewalls of the connecting portion and the guide portion;

[0028] The device housing is equipped with a positioning slider; the positioning slider is slidably embedded in the positioning guide groove.

[0029] Beneficial effects:

[0030] This application provides a guide rail hook and electronic device. A first engaging portion can move away from a second engaging portion under external force, increasing the distance between the two portions. During this distance increase, the guide rail can be installed into or removed from the mounting area between the first and second engaging portions. Furthermore, after the first engaging portion is reset, the width between the first and second engaging portions is not greater than the width of the guide rail, allowing the guide rail to engage within the mounting area.

[0031] Compared to guide rail hooks in related technologies that consist of multiple separate parts connected by hinges, the guide rail hook provided in this application eliminates the hinge design between parts, eliminating gaps between them. Instead, it utilizes the elastic deformation of the spring arm itself to open and close the first locking part, avoiding errors in stroke transmission during the opening and closing of the guide rail hook. Furthermore, the guide rail hook of this application does not require complex linkage between the parts; the opening and closing of the first locking part can be controlled solely by the spring arm, effectively simplifying the structure of the guide rail hook and reducing production costs.

[0032] Of course, any product implementing this application does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0046] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art based on this application are within the scope of protection of this application.

[0047] This application provides a guide rail hook, such as Figures 1 to 2b As shown, Figure 1 A schematic diagram of the guide rail hook provided in this application; Figure 2a for Figure 1 The cross-sectional view of the guide rail hook shown; Figure 2b for Figure 1The diagram shows a cross-sectional view of the guide rail hook in conjunction with the guide rail. The guide rail hook includes: a connecting part 1, a spring arm 2, a first locking part 31, and a second locking part 32; the fixed end 201 of the spring arm 2 is fixedly connected to the first end of the connecting part 1, and the movable end 202 of the spring arm 2 protrudes outward from the connecting part 1; the first locking part 31 is fixedly connected to the movable end 202 of the spring arm 2; the second locking part 32 is fixedly connected to the second end of the connecting part 1, located on the side corresponding to the position of the first locking part 31, and spaced apart from the first locking part 31; after the external force is eliminated, the first locking part 31 resets, and the width of the mounting area between the first locking part 31 and the second locking part 32 after the first locking part 31 resets is not greater than the width of the guide rail 100.

[0048] In this embodiment, the first latching portion 31 can move away from the second latching portion 32 under the action of an external force, thereby increasing the distance between the first latching portion 31 and the second latching portion 32. During the distance increase, the guide rail 100 can be installed into or removed from the installation area between the first latching portion 31 and the second latching portion 32. Furthermore, after the first latching portion 31 is reset, the width between the first latching portion 31 and the second latching portion 32 is not greater than the width of the guide rail, thus allowing the guide rail to latch into the installation area.

[0049] Compared to guide rail hooks in related technologies that consist of multiple separate parts connected by hinges, the guide rail hook provided in this application eliminates the hinge design between parts, eliminating gaps between them. Instead, it utilizes the elastic deformation of the spring arm 2 to open and close the first locking part 31, avoiding errors in stroke transmission during the opening and closing of the guide rail hook. Furthermore, the guide rail hook of this application does not require complex linkage between the parts; the opening and closing of the first locking part 31 can be controlled solely by the spring arm 2, effectively simplifying the structure of the guide rail hook and reducing production costs.

[0050] Specifically, in the initial state, the first latching part 31 is in a closed state. See also Figure 2a At this time, the mounting area between the first snap-fit ​​part 31 and the second snap-fit ​​part 32 can be adapted to the size of the guide rail 100, so that the first snap-fit ​​part 31 and the second snap-fit ​​part 32 can snap the guide rail 100 into the mounting area.

[0051] During installation of the guide rail 100, the first locking part 31 and the second locking part 32 are aligned with the guide rail 100, pressing the guide rail 100 into the installation area. During this pressing process, the two sides of the guide rail 100 press against the first locking part 31 and the second locking part 32, causing the elastic arm 2 to deform. This causes the first locking part 31 to move away from the second locking part 32. At this time, the first locking part 31 is in an open state, increasing the distance between it and the second locking part 32, allowing the guide rail 100 to enter the installation area. Once the guide rail 100 is in the installation area, the first locking part 31 is no longer pressed and returns to its original position under the elastic force of the elastic arm 2, allowing the first and second locking parts to clamp the guide rail 100, thus achieving stable and reliable clamping and locking.

[0052] When disassembling the guide rail 100, the first locking part 31 can be pulled away from the second locking part 32. Under external force, the first locking part 31 can move away from the second locking part 32, increasing the distance between them. At this point, the distance between the first locking part 31 and the second locking part 32 is greater than the size of the guide rail 100, releasing the clamp on the guide rail 100. Thus, the guide rail 100 can be disengaged from the mounting area.

[0053] In some embodiments of this application, the first latching portion 31 has a guide surface facing the second latching portion 32; and / or, the second latching portion 32 has a guide surface facing the first latching portion 31. In this embodiment, a rounded corner may be provided on the side of the first latching portion 31 and the second latching portion 32 facing the guide rail 100 to guide the installation of the guide rail 100.

[0054] The guide rail hook is compatible with DIN metal guide rails (DIN is a German standard) with a width of 35mm. Of course, the size of the guide rail hook can also be modified according to the actual situation so that the guide rail hook can be compatible with other models of guide rails.

[0055] In some embodiments, such as Figures 1 to 2b As shown, the first latching portion 31 can be spaced apart from the connecting portion 1, and the spaced area is the first latching groove 311; a portion of the second latching portion 32 can be spaced apart from the connecting portion 1, and the spaced area is the second latching groove 321; the two sides of the guide rail 100 are respectively embedded in the first latching groove 311 and the second latching groove 321. Of course, slots can also be directly provided on the first latching portion 31 and the second latching portion 32, and the guide rail 100 can be directly embedded in the first latching portion 31 and the second latching portion 32.

[0056] In some implementations of this application, such as Figures 1 to 2bAs shown, the guide rail hook also includes: a guide portion 4; the first end of the guide portion 4 is fixedly connected to the second end of the connecting portion 1, and the other end extends in a direction away from the elastic arm 2; the device housing 5 of the electronic device on which the guide rail hook is installed has a hook blocking portion 511, which is located between the first end and the second end of the connecting portion 1 and abuts against the elastic arm 2; when the second end of the guide portion 4 is subjected to a pulling force away from the first direction of the elastic arm 2, the guide portion 4 drives the connecting portion 1 and the elastic arm 2 to move in the first direction, and the elastic arm 2 is blocked by the hook blocking portion, so that the moving end 202 drives the first locking portion 31 to move in the opposite direction of the first direction, so that the distance between the first locking portion 31 and the second locking portion 32 increases.

[0057] In this embodiment, the guide portion of the guide rail hook extends the length of the guide rail hook, see [reference]. Figure 3 and Figure 4 , Figure 3 for Figure 1 The guide rail hook shown is installed in a partial cross-sectional view of an electronic device; Figure 4 for Figure 3 The front view. When the guide rail hook is installed inside the device housing 5 of the electronic device, the guide part 4 can extend out of the device housing 5, so that when the guide rail 100 is disassembled, it is not necessary to disassemble the device housing 5. By pulling the guide part 4, the first locking part 31 can be opened through the cooperation of the elastic arm 2 and the hook blocking part 511, thereby realizing the disassembly of the guide rail 100.

[0058] Specifically, when the guide rail 100 needs to be disassembled, the guide part 4 is pulled, causing the guide rail hook to move in the first direction. Since the hook blocking part 511 is fixed to the equipment housing 5, it does not move with the guide rail hook. When the elastic arm 2 moves in the first direction, the elastic arm 2 abuts against the hook blocking part 511. Under the obstruction of the hook blocking part 511, the moving end 202 of the elastic arm 2 is subjected to pressure away from the first direction and cannot move in the first direction, while the fixed end 201 of the elastic arm 2 can continue to move in the first direction with the guide rail hook. In other words, at this time, the elastic arm 2 deforms under the pressure of the hook blocking part 511, and the moving end 202 moves relative to the connecting part in a direction away from the first direction, thereby rotating around the fixed end 201 and causing the first locking part 31 to open, increasing the distance between the first locking part 31 and the second locking part 32. The first locking part 31 disengages from the guide rail 100, and the second locking part 32 disengages from the guide rail 100 during its movement in the first direction, so that the guide rail 100 can be removed from the guide rail hook. In this way, the guide rail hook can achieve bidirectional clamping and separation of the guide rail under the action of a single force. That is, by outputting a unidirectional pulling or pushing force to the guide rail hook, the first locking part 31 and the second locking part 32 can be engaged or disengaged from the guide rail 100.

[0059] During production, the positional relationship between the guide part 4 and the connecting part 1 can be adjusted according to actual needs. (See [reference]) Figures 1 to 2b The top surface of the guide part 4 can be positioned below the top surface of the main body 11 of the connecting part 1, so that the guide part 4 avoids the hook blocking part 511.

[0060] In some embodiments, the guide portion 4 can be connected to the first latching portion 31 or the moving end 202 of the elastic arm 2, so that pulling the guide portion 4 can directly drive the first latching portion 31 to open. Alternatively, guide portions 4 can be provided at the first end and the second end of the connecting portion 1, so that pulling the guide portions 4 at both ends of the connecting portion 1 at the same time can cause the first latching portion 31 and the second latching portion 32 to disengage from the guide rail 100 simultaneously.

[0061] In some embodiments, see Figures 1 to 2b A guide support groove 41 can be provided on the guide portion 4. As mentioned earlier, the guide portion 4 extends the length of the guide rail hook, see [reference]. Figure 3 and Figure 4 The second support plate 515 on the outer casing 5 is inserted into the guide support groove 41, so that the top surface of the second support plate 515 abuts against the bottom surface of the guide support groove 41, thereby providing support for the guide part 4 and preventing the guide part 4 from sagging under the action of gravity.

[0062] In some implementations of this application, such as Figures 1 to 2b As shown, the connecting part 1 includes: a main body 11 and a fixed frame 12 that are connected to each other. The main body 11 has a through swing arm opening 111. The fixed frame 12 includes: a top beam 121 and side walls 122 located at both ends of the top beam 121. The elastic arm 2 is located between the two side walls 122. The fixed end 201 of the elastic arm 2 is fixedly connected to the top beam 121. The movable end 202 of the elastic arm 2 passes through the swing arm opening 111.

[0063] In this embodiment, see Figures 1 to 2b The elastic arm 2 passes through the swing arm opening 111 of the main trunk 11, such that the fixed end 201 and the moving end 202 of the elastic arm 2 are located on the upper and lower sides of the main trunk 11, respectively. See below. Figure 3 and Figure 4 The hook blocking part 511 can be positioned above the main stem 11, both to abut against the elastic arm 2 and to restrict the upward movement of the guide rail hook. Simultaneously, positioning the hook blocking part 511 above the main stem 11 frees up space below the main stem 11. For example... Figure 3 and Figure 4 As shown, at this time, a first support plate 513 can be set below the main trunk 11 to provide upward support for the guide rail hook.

[0064] In some embodiments, see Figure 3 and Figure 4 The fixed frame 12 can extend into the hook positioning groove 514 on the device housing 5 of the electronic device. The top crossbeam 121 of the fixed frame 12 extends into the hook positioning groove 514 to limit the initial position of the guide rail hook installation. Furthermore, when the guide rail hook moves to its maximum limit position, both sides of the fixed frame 12 abut against both sides of the hook positioning groove 514, thereby limiting the range of movement of the guide rail hook. Simultaneously, the hook positioning groove 514 also serves as a partial limit for the overall installation of the guide rail hook and as a mid-range limit during the entire movement process.

[0065] In some implementations of this application, such as Figures 1 to 2b As shown, a feedback block 13 is provided on the guide section 4; see also Figure 3 and Figure 4 The feedback block 13 is used to cooperate with the feedback groove 512 of the device housing 5 of the electronic device that is mounted on the guide rail hook. When the feedback block 13 is inserted into or removed from the feedback groove 512, it can provide the user with tactile feedback to indicate that it has been moved into place.

[0066] In this embodiment, the user is provided with tactile feedback by the insertion or removal of the feedback block 13 and the feedback slot 512 to indicate that the movement has been completed.

[0067] For details, see Figures 2a to 3 The guide section 4 has a slot, and the feedback block 13 is disposed within the slot and connected to either side wall of the slot via a spring rod. When the guide rail hook is pushed or pulled, the feedback groove 512 on the device housing 5 of the electronic device passes through the feedback block 13 and presses down on the feedback block 13. The feedback block 13 moves downward after being pressed, and at this time, the spring rod stores force. When the feedback block 13 is fully inserted into or completely disengaged from the feedback groove 512, the spring rod releases its force, causing the feedback block 13 to reset. The reset action of the feedback block 13 causes the guide rail hook to vibrate, providing the user with tactile feedback to indicate that it has moved into place.

[0068] In some implementations of this application, such as Figures 1 to 2b As shown, a positioning guide groove 14 is provided on the side wall of the connecting part 1 and / or the guide part 4 for cooperating with the positioning slider of the device housing 5 of the electronic device on which the guide rail hook is installed. The positioning slider is slidably embedded in the positioning guide groove 14.

[0069] In this embodiment, the positioning guide groove 14 on the connecting part 1 and / or the guide part 4 cooperates with the equipment housing 5. Thus, when the guide hook slides along the first direction, the positioning guide groove 14 provides guidance for the guide hook, thereby achieving lateral and longitudinal positioning of the guide hook. The lateral direction is the direction in which the guide hook slides; the longitudinal direction is the direction from the fixed end 201 to the moving end 202 when the elastic arm 2 is not deformed. That is, the positioning guide groove 14 extending along the first direction ensures that the guide hook slides only laterally and restricts the longitudinal displacement of the guide hook, thereby achieving positioning.

[0070] In some embodiments, see Figures 1 to 4 A handle position 15 can be provided on the side of the guide part 4 away from the connecting part 1. In this way, when the guide part 4 extends out of the device housing 5 of the electronic device, the handle position 15 can be pulled directly to drive the guide rail hook to slide along the hook mounting groove 51 of the device housing 5.

[0071] In some embodiments, see Figures 1 to 4 A reset block 16 can be provided on the guide section 4, and an elastic element 52 can be provided inside the electronic device. The elastic element 52 extends along the sliding direction of the guide rail hook, with one end abutting against the reset block 16 and the other end fixedly connected to the device housing 5. When the guide rail hook is pulled in the first direction, the reset block 16 moves in the first direction and presses against the elastic element 52, at which time the elastic element 52 stores force. After the guide rail 100 is disassembled, the guide rail hook is released, the elastic element 52 releases its elastic force, pushes the reset block 16, and drives the guide rail hook to reset.

[0072] This application also provides an electronic device, which can be a PLC (Programmable Logic Controller) or a servo controller, or other device that needs to be mounted on a guide rail. Figure 3 and Figure 4 As shown, the electronic device includes: a device housing 5 and a guide rail hook of any of the above embodiments; the device housing 5 is provided with a hook mounting groove 51; the guide rail hook is slidably mounted in the hook mounting groove 51.

[0073] In this embodiment, the guide rail hook can slide along the hook mounting groove 51. During the sliding process, the first locking part 31 of the guide rail hook can move away from the second locking part 32 under the action of external force, so as to increase the distance between the first locking part 31 and the second locking part 32, so that the guide rail 100 can be installed in the mounting area between the first locking part 31 and the second locking part 32, or removed from the mounting area.

[0074] Compared to guide rail hooks in related technologies that consist of multiple separate parts connected by hinges, the guide rail hook provided in this application eliminates the hinge design between parts, eliminating gaps between them. Instead, it utilizes the elastic deformation of the spring arm 2 to open and close the first locking part 31, avoiding errors in stroke transmission during the opening and closing of the guide rail hook. Furthermore, the guide rail hook of this application does not require complex linkage between the parts; the opening and closing of the first locking part 31 can be controlled solely by the spring arm 2, effectively simplifying the structure of the guide rail hook and reducing production costs.

[0075] In some embodiments of this application, such as Figure 3 and Figure 4 As shown, the hook mounting groove 51 includes a hook blocking part 511; the hook blocking part 511 is located between the first end and the second end of the connecting part 1; the hook blocking part 511 is used to abut against the elastic arm 2.

[0076] In this embodiment, the elastic arm 2 is deformed by the hook blocking part 511, and its technical effect is the same as that of the previous embodiment, so it will not be described in detail here.

[0077] In some implementations of this application, such as Figure 3 and Figure 4 As shown, when the guide part 4 is present on the guide rail hook, a feedback block 13 is provided on the guide part 4; the hook mounting groove 51 includes a feedback groove 512.

[0078] In this embodiment, the cooperation relationship and technical effect between the feedback block 13 and the feedback slot 512 are the same as in the previous embodiment, and will not be described in detail here.

[0079] In some implementations of this application, such as Figure 3 and Figure 4 As shown, when the guide part 4 is present on the guide rail hook, a positioning guide groove 14 is provided on the side wall of the connecting part 1 and the guide part 4; a positioning slider is provided on the equipment housing 5; the positioning slider is slidably embedded in the positioning guide groove 14.

[0080] In this embodiment, the cooperation relationship and technical effect between the positioning guide groove 14 and the positioning slider are the same as in the previous embodiment, and will not be described in detail here.

[0081] The above description is merely a preferred embodiment of this application and is not intended to limit the scope of protection of this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application are included within the scope of protection of this application.
