Description

Technical Field

[0001] This utility model relates to the technical field of isolation safety barrier equipment, and in particular to a quick-connect type isolation safety barrier. Background Technology

[0002] The isolation safety barrier transmits voltage and current signals from the hazardous area to the safe area via isolated transmitters, either as a single channel or two independent channels. It can also be networked via serial communication within the safe area through a configured communication interface. This intelligent safety barrier product allows users to set the input signal type and output range using a dedicated programmer or computer. The isolation safety barrier prevents hazardous energy from entering the hazardous area through intrinsically safe circuit terminals, improving the explosion-proof performance of the system's intrinsically safe circuits, increasing the system's anti-interference capability, and significantly improving the system's operational reliability. Its function is implemented as follows: a Zener diode (Z) is used to limit the voltage; when the circuit voltage approaches the safe voltage limit, the Zener diode conducts, keeping the voltage across it below the safe voltage limit.

[0003] For example, patent document CN220187843U discloses an isolation safety barrier for an IEPE vibration acceleration sensor, including a main body, a connector, and a push plate. The bottom of the main body has a guide rail that slidably connects to the main body. A connector is fixedly connected to the main body on one side. An insert is fixedly connected to the main body on the side of the main body away from the connector. Push plates are located on both sides of the connector, movably connecting to the connector. This isolation safety barrier improves the installation stability between side-by-side unit bodies. As shown in the aforementioned patent, existing isolation safety barriers typically have slots directly provided on the back of the isolation safety barrier unit body, allowing for sliding installation on a mounting strip inside the distribution box via a slot-rail connection. This enables the side-by-side connection of numerous isolation safety barrier units on the same mounting strip, thereby increasing the installation capacity. However, when at least one safety barrier is damaged, it is necessary to remove numerous other intact safety barriers on one side of it according to its installation position before it can be removed from the mounting strip. The entire disassembly and maintenance process is cumbersome, time-consuming, labor-intensive, and prone to damaging other components. Because several safety barriers are installed on the mounting strip in the distribution box with no gaps, their movable space and angle are limited. In particular, the safety barriers are also blocked by other mechanisms on their upper and lower sides, making the removal operation of the safety barriers during later maintenance more difficult. Due to the restrictions of other safety barriers on both sides and other mechanisms on the upper and lower sides, the safety barrier to be removed cannot move freely left and right or up and down. There is only a small range of up and down shaking and pull-out longitudinal translation. This also makes it difficult to remove some safety barriers with adjustable slots, as their slot adjustment structure is blocked by other mechanisms, increasing the difficulty of disassembly and assembly. Utility Model Content

[0004] The purpose of this utility model is to provide a quick-connect type safety barrier that can be plugged in and unplugged to achieve flexible disassembly and assembly in small spaces, thereby improving the convenience and efficiency of disassembly and assembly. This solves the problems of existing safety barriers being cumbersome to disassemble and assemble, having a high workload, and being time-consuming and labor-intensive. In addition, the left, right, top, and bottom sides of the installation position are easily blocked, which restricts the direction and space of its movement, resulting in increased disassembly and assembly difficulty and reduced efficiency and convenience.

[0005] The technical solution adopted by this utility model is as follows: a quick-connect type isolation safety barrier, including a mounting base plate detachably connected to the inner wall of the distribution box, a plurality of insertion seats are installed side by side on the top surface of the mounting base plate, and the insertion seats can be limited and assembled with the insertion components that are snapped onto the isolation safety barrier unit, thereby limiting the working position of the isolation safety barrier unit relative to the mounting base plate; the insertion components are assembled and connected to the isolation safety barrier unit in such a way that the snap-fit ​​connector can be limited and snapped into the back slot of the isolation safety barrier unit; the insertion seats limit their relative position to the insertion components by positioning the limiting connector of the insertion components in the limiting socket.

[0006] According to a preferred embodiment, the locking connector is installed on the top surface of the insertion plate of the insertion assembly, and the insertion posts and the limiting connector are symmetrically arranged on the bottom surface of the insertion plate. The insertion plate also has a first through hole at the center of the plate body that exposes at least a portion of the bottom surface of the locking connector.

[0007] According to a preferred embodiment, a top-pressure limiting post is provided through the trapezoidal insert of the locking connector, such that a portion of the top-pressure limiting post extends into the first through hole. A top-pressure head is connected to the upper axial end of the top-pressure limiting post, and the surface of the top-pressure head is covered with an anti-slip pad. A first receiving cavity for accommodating the top-pressure head is also provided on the surface of the trapezoidal insert, and a first limiting spring for limiting the initial working position of the top-pressure head is sleeved on the post of the top-pressure limiting post.

[0008] According to a preferred embodiment, the limiting connector includes a plug post installed on the bottom surface of the plug-in plate and parallel to the plug post, and a trapezoidal limiting end connected to the end of the plug post away from the plug-in plate.

[0009] According to a preferred embodiment, the insert includes a base connected to the mounting base plate and an elastic positioning mechanism disposed inside the base plate to adjustably position the limiting insert.

[0010] According to a preferred embodiment, the surface of the base away from the mounting base plate is provided with a limiting socket for accommodating the limiting connector and an auxiliary socket for accommodating the insertion post, wherein the limiting socket and the auxiliary socket are provided in parallel.

[0011] According to a preferred embodiment, the seat body is further provided with a horizontal receiving cavity that communicates with the limiting insertion hole and a vertical receiving cavity that communicates with the end of the horizontal receiving cavity that is away from the limiting insertion hole.

[0012] According to a preferred embodiment, the elastic positioning mechanism includes a horizontal positioning column, a vertical adjusting rod, an adjusting step block, and a second limiting spring. The horizontal positioning column is movably inserted into the communicating chamber formed by the horizontal receiving cavity and the vertical receiving cavity, and the adjusting step block is movably inserted through the through groove of the horizontal positioning column. The top of the adjusting step block is connected to the vertical adjusting rod located in the vertical receiving cavity, and the bottom surface of the adjusting step block is connected to the second limiting spring that can limit its initial working position.

[0013] According to a preferred embodiment, the end of the transverse positioning column away from the adjusting ladder block is connected to a triangular limiting block that can be adjusted to partially insert into the limiting hole; a third limiting spring on the column body of the transverse positioning column can limit its initial working position, wherein one end of the third limiting spring abuts against the triangular limiting block.

[0014] According to a preferred embodiment, the mounting base plate is further provided with a plurality of through-holes spaced apart along its edge.

[0015] The beneficial effects of this utility model are:

[0016] The insert socket provided in this application enables quick insertion and connection with the plug-in assembly, thereby improving the ease of installation of the safety barrier unit and reducing the difficulty of disassembly. In particular, the insert socket allows the plug-in assembly to be easily pulled out and separated by pressing and releasing, avoiding the defects of other mechanisms in the distribution box obstructing the safety barrier unit and making disassembly difficult. This allows the plug-in assembly and the safety barrier unit to be removed and removed by longitudinal insertion and removal. The plug-in assembly limits the assembly stability and ease of disassembly with the safety barrier unit through snap-fit ​​and elastic pressing, thereby improving the efficiency of the safety barrier unit's assembly and disassembly. It achieves the effect of independent assembly and disassembly of several safety barrier units, allowing for selective and independent disassembly and assembly of damaged safety barrier units. It also reduces the need for operating space, enabling flexible assembly and disassembly of the plug-in assembly and the safety barrier unit in small spaces where the surroundings are obstructed or restricted.

[0017] The elastic positioning mechanism provided in this application can abut and limit the limit connector inserted into the limit socket, thereby adjusting the relative assembly position of the insertion base and the insertion assembly. Furthermore, it can release the limit by pressing and adjusting, thus facilitating the removal and disassembly of the insertion assembly and the isolation safety barrier unit. This improves the ease of disassembly and assembly, avoiding the drawback of the original up-and-down pull-type movable slot being blocked by surrounding mechanisms and unable to be effectively pulled and removed. This application only requires longitudinal pressing and insertion / removal operations to complete the removal process, avoiding the defect of surrounding mechanisms blocking and restricting the isolation safety barrier from all sides, thus preventing convenient removal.

[0030] The following is a detailed explanation with reference to the accompanying drawings.

[0031] Example 1

[0032] This application provides a quick-connect type isolation safety barrier, which includes a mounting base plate 1, a plug-in socket 2, a plug-in assembly 3, and an isolation safety barrier unit 4.

[0033] according to Figure 1-6In one specific embodiment, the mounting base plate 1 is detachably connected to the inner wall of the distribution box, thereby replacing the mounting strip and facilitating the pre-attachment of multiple insertion sockets 2 on the mounting base plate 1. Several insertion sockets 2 are mounted side-by-side on the top surface of the mounting base plate 1. The insertion sockets 2 can be positioned and assembled with the insertion assembly 3 that is snapped onto the isolation safety barrier unit 4, thereby defining the working position of the isolation safety barrier unit 4 relative to the mounting base plate 1. The insertion assembly 3 is assembled and connected to the isolation safety barrier unit 4 in such a way that the snap-fit ​​connector 31 can be snapped into the slot on the back of the isolation safety barrier unit 4. The insertion base 2 defines its relative position to the insertion assembly 3 by positioning the limiting connector 32 of the insertion assembly 3 within the limiting socket 23. Specifically, when the limiting connector 32 and the insertion post 33 of the insertion assembly 3 are respectively inserted into the limiting socket 23 and auxiliary socket 24 of the insertion base 2, the elastic positioning mechanism 22 of the insertion base 2 defines the position of the limiting connector 32 within the limiting socket 23 by abutting against the surface of the trapezoidal limiting end 322 of the limiting connector 32. The insertion base 2 provided in this application can cooperate with the insertion assembly 3 to achieve quick insertion and connection, thereby improving the ease of installation of the isolation safety barrier unit 4 and reducing the difficulty of disassembly. In particular, the insertion base 2 allows the insertion assembly 3 to be easily pulled out and separated by pressing and releasing, avoiding the defect of other mechanisms in the distribution box forming a perimeter around the isolation safety barrier unit 4 without requiring disassembly. This allows the insertion assembly 3 and the isolation safety barrier unit 4 to be disassembled by longitudinal insertion and removal. The plug-in component 3 can limit the assembly stability and easy disassembly of the isolation safety barrier unit 4 by snap-fit ​​and elastic pressing, thereby improving the disassembly and assembly efficiency of the isolation safety barrier unit 4, realizing the independent disassembly and assembly of several isolation safety barrier units 4, so that damaged isolation safety barrier units 4 can be selectively disassembled and assembled independently, and reducing the requirement for operating space, realizing flexible disassembly and assembly of the plug-in component 3 and the isolation safety barrier unit 4 in small spaces where the surroundings are blocked or restricted.

[0034] Preferably, the mounting base plate 1 has multiple through-holes 11 spaced apart along its edge to position and install it in the distribution box. Specifically, the mounting base plate 1 is installed inside the distribution box using screws, bolts, or limiting blocks inserted into the through-holes 11, thereby positioning the installation position of the isolation safety barrier unit 4.

[0035] Preferably, the insertion base 2 includes a base body 21 connected to the mounting base plate 1 and an elastic positioning mechanism 22 disposed inside the base body 21 to adjustably position the limiting connector 32. Preferably, the base body 21 is fixedly connected to the mounting base plate 1 by integral molding, fixed adhesion, bolt connection, or other means. More preferably, the surface of the base body 21 away from the mounting base plate 1 has a limiting insertion hole 23 for accommodating the limiting connector 32 and an auxiliary insertion hole 24 for accommodating the insertion post 33. Specifically, the limiting insertion hole 23 and the auxiliary insertion hole 24 are provided in parallel. The elastic positioning mechanism 22 provided in this application can abut and limit the insertion of the limiting connector 32 inserted into the limiting socket 23, thereby adjusting the relative assembly position of the insertion base 2 and the insertion assembly 3. Furthermore, it can release the limit by pressing and adjusting, thereby facilitating the removal and disassembly of the insertion assembly 3 and the isolation safety barrier unit 4, improving the ease of disassembly and assembly, and avoiding the disadvantage of the original up-and-down pull-type movable slot being blocked by the surrounding mechanism and unable to be effectively pulled and removed. This application only requires longitudinal pressing and insertion / removal operations to complete the removal process, avoiding the defect of the surrounding mechanism blocking and restricting the isolation safety barrier from all sides and making it difficult to remove.

[0036] Preferably, the base 21 also includes a horizontally accommodating cavity 211 that communicates with the limiting insertion hole 23 and a vertically accommodating cavity 212 that communicates with the end of the horizontally accommodating cavity 211 away from the limiting insertion hole 23. Specifically, the vertically accommodating cavity 212 can construct a large bottom cavity to accommodate the adjusting step block 223 that can move up and down while limiting the movement direction of the vertical adjusting rod 222.

[0037] Preferably, the elastic positioning mechanism 22 includes a lateral positioning column 221, a vertical adjusting rod 222, an adjusting step block 223, and a second limiting spring 224. Preferably, the lateral positioning column 221 is movably inserted into the communicating chamber formed by the horizontal receiving cavity 211 and the vertical receiving cavity 212. More preferably, the adjusting step block 223 is also movably inserted into the through groove 2211 of the lateral positioning column 221. Preferably, the top end of the adjusting step block 223 is connected to the vertical adjusting rod 222 located in the vertical receiving cavity 212. Preferably, the bottom surface of the adjusting step block 223 is also connected to a second limiting spring 224 that can limit its initial working position. The adjusting step block 223 provided in this application can drive the lateral positioning column 221 to move laterally during descent by the upwardly inclined and acute-angled ramp surface on its right side, thereby causing the lateral positioning column 221 to move laterally to the right. This application provides a second limiting spring 224 at the bottom of the adjusting ladder block 223, which limits the initial working position of the adjusting ladder block 223. As the vertical adjusting rod 222 moves downward, the adjusting ladder block 223 descends and compresses the second limiting spring, simultaneously driving the lateral positioning column 221 to move laterally to the right, thus releasing the restriction on the limiting connector 32. The elastic positioning mechanism 22 provided in this application can release the restriction by longitudinal pressing, facilitating the removal and removal of the connector 3. This significantly improves the overall ease of assembly and disassembly. Furthermore, the longitudinal pressing point is easily controlled by the operator and is not easily obstructed or restricted by other surrounding mechanisms, enhancing the convenience of assembly and disassembly. It does not conflict with the installation positions of other mechanisms and enables efficient, barrier-free assembly and disassembly operations.

[0038] Preferably, the end of the transverse positioning column 221 away from the adjusting ladder block 223 is connected to a triangular limiting block 2212 that can be adjusted to partially insert into the limiting socket 23. Preferably, a third limiting spring 2213 is provided on the column body of the transverse positioning column 221 to limit its initial working position. More preferably, one end of the third limiting spring 2213 abuts against the triangular limiting block 2212, so that the third limiting spring 2213 changes its compression degree on the transverse positioning column 221 by the translation of the triangular limiting block 2212. The triangular limiting block 2212 provided in this application can press against the upper end surface of the trapezoidal limiting end 322 of the limiting plug 32, thereby limiting the position of the limiting plug 32 in the limiting socket 23, realizing the assembly connection between the insert base 2 and the plug-in assembly 3. Furthermore, the triangular limiting block 2212 can be adjusted and automatically reset as needed by the movable limiting of the third limiting spring 2213, thereby improving the convenience of insertion and disassembly when the insert base 2 and the plug-in assembly 3 are combined.

[0039] Preferably, the plug-in assembly 3 includes a locking connector 31, a limiting connector 32, an insertion post 33, and a plug-in middle plate 34. Preferably, the locking connector 31 is mounted on the top surface of the plug-in middle plate 34. Preferably, the insertion post 33 and the limiting connector 32 are symmetrically arranged on the bottom surface of the plug-in middle plate 34. Preferably, a top-pressing limiting post 312 is passed through the trapezoidal insertion strip 311 of the locking connector 31, so that part of the top-pressing limiting post 312 extends into the first through hole 341. Preferably, a top-pressing head 313 is connected to the axial upper end of the top-pressing limiting post 312, and the surface of the top-pressing head 313 is also covered with an anti-slip soft pad 314. Preferably, the anti-slip soft pad 314 is a material with a large coefficient of friction, such as a silicone pad layer, which can improve surface adhesion when deformed under pressure. Preferably, a first receiving cavity 315 for accommodating the pressing head 313 is further formed on the surface of the trapezoidal insert 311, and a first limiting spring 316 for limiting the initial working position of the pressing head 313 is also sleeved on the column of the pressing limiting post 312. Specifically, when no external force is applied, the pressing head 313 covered with the anti-slip pad 314 can abut against the bottom surface of the slot on the back of the isolation safety barrier unit 4, thereby limiting the relative sliding between the isolation safety barrier unit 4 and the locking connector 31, so as to ensure the stability of the sliding engagement between the two. Preferably, a pull ring is provided at the axial lower end of the pressing limiting post 312 extending to the first through hole 341, so that the operator can pull the pull ring to move the pressing head 313 down into the first receiving cavity 315, thereby releasing the pressing head 313 from the pressing limit when the trapezoidal insert 311 is engaged with the back slot, so as to facilitate the release of the mutual connection between the trapezoidal insert 311 and the back slot. The locking connector 31 provided in this application can improve the connection stability between the plug-in component 3 and the isolation safety barrier unit 4 through the plug-in connection and synchronous elastic pressure limit. Furthermore, the elastic pressure limit can be manually released as needed, thereby facilitating the disassembly and assembly of the plug-in component 3 and the isolation safety barrier unit 4, and improving the convenience of disassembly and assembly and the stability of assembly.

[0040] Preferably, the limiting connector 32 includes a plug post 321 mounted on the bottom surface of the connecting plate 34 and parallel to the plug post 33, and a trapezoidal limiting end 322 connected to the end of the plug post 321 away from the connecting plate 34. Preferably, the connecting plate 34 also has a first through hole 341 at the center of its body, which exposes at least a portion of the bottom surface of the locking connector 31.

[0041] Preferably, the isolation safety barrier unit 4 adopts an existing conventional isolation safety barrier product with a back slot, ensuring its versatility and the universality of this structure. Specifically, the isolation safety barrier unit 4 can be an existing product with a slot having a trapezoidal cross-section, such as the SFX141-single-channel switch input relay output type safety barrier.

[0042] The disassembly and assembly method of this application is as follows:

[0043] The mounting base plate 1 is pre-installed on the inner wall of the distribution box or the frame by means of bolts / screws, and the insert 2 is pre-assembled with the mounting base plate 1 as a whole.

[0044] Manually pulling the pull ring causes the pressing head 313 to retract into the first receiving cavity 315, thereby engaging the locking connector 31 from the side of the isolation safety barrier unit 4 into the back slot of the isolation safety barrier unit 4. Both the locking connector 31 and the back slot have matching isosceles trapezoidal cross sections. The bottom surface of the isosceles trapezoidal cross section defined by the back slot is the longer trapezoidal bottom surface, and its opening surface is the shorter trapezoidal top surface, thus ensuring the effectiveness of the locking and limiting connection between the two. Then, the external force pulling on the pull ring is released, so that the pressing limiting post 312 and the pressing head 313 move out of the first receiving cavity 315 under the reset push of the first limiting spring 316 and abut against the bottom surface of the back slot of the isolation safety barrier unit 4. The reaction force is applied to the locking connector 31, so that the two are subjected to a force perpendicular to the locking direction, which increases the friction of the contact surface and thus improves the stability of their relative positions.

[0045] Align the limiting connector 32 and the insertion post 33 with the limiting socket 23 and the auxiliary socket 24 on the same base 21, respectively, and insert them into them. The limiting connector 32 pushes the transverse positioning square post 221 to move laterally and then abuts and limits it, thereby ensuring the limiting stability of the insertion connection.

[0046] When it is necessary to remove the plug-in assembly 3 and the isolation safety barrier unit 4, first press the vertical adjustment rod 222 to release the restriction of the horizontal positioning column 221 on the limiting plug 32, and then pull it out directly. For subsequent operations on the isolation safety barrier unit 4, after pulling the pull ring again to release the top pressure limit of the top pressure head 313, move it laterally to release the restriction between the locking connector 31 and the back slot, thus enabling the removal and replacement of the isolation safety barrier unit 4. In this application, the plug-in assembly 3 can be fully assembled and used; only the isolation safety barrier unit 4 needs to be replaced according to the working conditions.
