Description

Technical Field

[0001] This application relates to the field of installation and fixing technology, and in particular to an installation frame. Background Technology

[0002] Circuit breakers (air circuit breakers) are a common electrical safety protection device. They are installed in household circuits, home appliances, and electrical equipment used in commercial settings to improve circuit safety.

[0003] Currently, the assembly of circuit breakers generally requires the use of screws to fix the circuit breaker in the set position. Screws are needed for installation, operation, maintenance and replacement, which is inconvenient and inefficient. Summary of the Invention

[0004] Based on this, this application proposes an installation frame to address the problems of inconvenient and inefficient installation and maintenance of circuit breakers. This installation frame has the technical effect of facilitating installation and disassembly and improving operational efficiency.

[0005] A mounting bracket includes a base plate, which comprises a first fixing plate and a second fixing plate rotatably connected. The first fixing plate has a first fixing position, and the second fixing plate has a second fixing position. Both the first and second fixing plates have a first mounting surface and a second mounting surface facing the same side. The base plate has a pre-installed state and a fixed state. When the base plate is in the pre-installed state, the first and second fixing plates can rotate relative to each other, and at least one of the first and second fixing positions is allowed to move relative to the component to be fixed. When the base plate is in the fixed state, the first and second mounting surfaces are coplanar, and both the first and second fixing positions are engaged with the component to be fixed.

[0006] In one embodiment, the mounting frame further includes a locking element for locking the first fixing plate and the second fixing plate when the base plate is in a fixed state.

[0007] In one embodiment, the end of the first fixing plate away from the second fixing plate forms the first fixing position, and the end of the second fixing plate away from the first fixing plate forms the second fixing position;

[0008] The two ends of the component to be fixed are provided with slots. When the base plate is in the pre-installed state, at least one of the first fixing position and the second fixing position can move relative to the slots at both ends.

[0009] When the base plate is in a fixed state, both the first fixing position and the second fixing position are engaged in the slot.

[0010] In one embodiment, the first fixing plate and the second fixing plate are arranged along a second direction, and the mounting frame further includes at least one limiting member, all of which are arranged at intervals along the first direction on the base plate;

[0011] The first direction and the second direction are intersecting.

[0012] In one embodiment, the limiting member includes a first limiting block and a second limiting block disposed opposite to each other along the second direction. The first limiting block is disposed on the first fixed plate, and the second limiting block is disposed on the second fixed plate. Each pair of the first limiting block and the second limiting block disposed opposite to each other along the second direction forms a limiting group.

[0013] At least two sets of the limiting groups are arranged at intervals along the first direction on the base plate.

[0014] In one embodiment, the locking element includes a support rod, one end of which is fitted onto the first fixing plate and the other end of which is fitted onto the second fixing plate to lock the first fixing plate and the second fixing plate together.

[0015] Furthermore, at least one end of the support rod is detachably connected to the base plate.

[0016] In one embodiment, at least one set of the limiting group has a first mounting groove and a second mounting groove disposed opposite to each other in the second direction, and one end of the support rod is fitted into the first mounting groove and the other end is fitted into the second mounting groove.

[0017] In one embodiment, at least one end of the support rod includes an elastic segment that can deform under stress.

[0018] In one embodiment, the support rod includes a rod body and an elastic segment disposed at at least one end thereof, the elastic segment including a ball and an elastic part, the elastic part being elastically connected between the ball and the rod body.

[0019] In one embodiment, at least one of the limiting members is movably disposed relative to the base plate.

[0020] In one embodiment, the first fixing plate and / or the second fixing plate are provided with fixing holes.

[0021] The aforementioned mounting frame is used to assemble components to be fixed, which can be circuit breakers or other structures. During assembly, one end of the component to be fixed can be first fixed to the first fixing position, and the other end can be movably connected to the second fixing position 121, or both ends can be movably connected to the base plate. Then, the first fixing plate and the second fixing plate are controlled to rotate relative to each other, causing one or both sides of the movably connected side to interlock. At this time, the first and second assembly surfaces are coplanar and fit against the side of the component to be fixed facing the base plate, thus completing the assembly of the component. When it is necessary to remove the component, the first and second fixing plates are controlled to rotate relative to each other, separating at least one fixing position (at least one of the first and second fixing positions) from the component. The component can then be removed from the base plate for maintenance or replacement. Thus, the mounting frame provided in this application facilitates the installation and disassembly of components and improves operational efficiency. Attached Figure Description

Detailed Implementation

[0029] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0030] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0031] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0032] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0033] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0034] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0035] In actual circuit installations, circuit breakers or air switches are generally required to ensure timely tripping in case of circuit abnormalities, thus protecting circuit safety. When assembling circuit breakers or air switches into the electrical box, the current assembly method typically involves fixing them in place with screws. When replacing a circuit breaker or air switch, the screws are removed, and the circuit breaker or air switch is taken out.

[0036] However, this disassembly and assembly method requires the use of tools to tighten screws during installation, maintenance and replacement operations, which is inconvenient and inefficient.

[0037] To solve the above problems, see Figure 1 This application provides an mounting frame 100 for assembling electrical appliances such as circuit breakers and air compressor switches or other structural components 200 to be fixed.

[0038] Specifically, see Figures 2 to 4 The mounting frame 100 includes a base plate 10, which includes a first fixing plate 11 and a second fixing plate 12 that are rotatably connected. The first fixing plate 11 has a first fixing position 111, and the second fixing plate 12 has a second fixing position 121. The first fixing plate 11 and the second fixing plate 12 have a first mounting surface 112 and a second mounting surface 122 facing the same side.

[0039] The base plate 10 has a pre-installed state and a fixed state. When the base plate 10 is in the pre-installed state, the first fixed plate 11 and the second fixed plate 12 can rotate relative to each other, and at least one of the first fixed position 111 and the second fixed position 121 is allowed to move relative to the fixed member 200.

[0040] When the base plate 10 is in a fixed state, the first assembly surface 112 and the second assembly surface 122 are coplanar, and the first fixing position 111 and the second fixing position 121 are both engaged with the part to be fixed 200.

[0041] Understandably, the component to be fixed 200 is also provided with a first mating part and a second mating part that respectively mate with the first fixing position 111 and the second fixing position 121. When the base plate 10 is in the pre-installed state, the first mating part of the component to be fixed 200 can be fixed to the first fixing position 111, and the second mating part can be movably connected to the second fixing position 121. Alternatively, the first mating part can be movably connected to the first fixing position 111 while the second mating part is movably connected to the second fixing position 121. Then, the first fixing plate 11 and the second fixing plate 12 can be controlled to rotate relative to each other, so that the movably connected first mating part and the first fixing position 111, and / or the movably connected second mating part and the second fixing position 121 can be engaged with each other. At this time, the first assembly surface 112 and the second assembly surface 122 are coplanar and fit against the side of the component to be fixed 200 facing the base plate 10, thereby completing the assembly of the component to be fixed 200.

[0042] In one embodiment, the first fixing position 111 and the first mating part can be either a protrusion or a groove, and the second fixing position 121 and the second mating part can also be either a protrusion or a groove. When the protrusion is inserted into the groove, the two will not separate from each other when there is no external force.

[0043] Furthermore, when it is necessary to remove the component to be fixed 200, the first fixing plate 11 and the second fixing plate 12 of the control rotation connection rotate relative to each other, separating at least one of the fixing positions (at least one of the first fixing position 111 and the second fixing position 121) from the component to be fixed 200. At this time, the component to be fixed 200 can be removed from the base plate 10 for maintenance or replacement.

[0044] Thus, the mounting frame 100 provided in this application can facilitate the installation and disassembly of the component to be fixed 200 and improve operational efficiency.

[0045] A first fixing plate 11 and a second fixing plate 12 are arranged along a second direction L2. In one embodiment, the first fixing plate 11 may include multiple first sub-plates, and multiple first support plates are also arranged along the second direction L2 and connected in pairs. The connection between any two first sub-plates can be fixed or rotatable. Similarly, the second fixing plate 12 may include multiple second sub-plates, and multiple second support plates are also arranged along the second direction L2 and connected in pairs. The connection between any two second sub-plates can be fixed or rotatable. The interconnected first sub-plates and second sub-plates are rotatably connected. A first fixing position 111 is provided on any first sub-plate, and a second fixing position 121 is fixed on any second sub-plate.

[0046] In one embodiment, the mounting frame 100 further includes a locking member 30, which is used to lock the first fixing plate 11 and the second fixing plate 12 when the base plate 10 is in a fixed state, so that the first fixing plate 11 and the second fixing plate 12 are fixed and the member to be fixed 200 is locked on the base plate 10.

[0047] Understandably, even if the fastener 200 or the base plate 10 is subjected to force, the fastener 200 will not detach from the base plate 10. If it is necessary to remove the fastener 200, the locking state of the locking member 30 is canceled, and then the first fixing plate 11 and the second fixing plate 12 are controlled to rotate relative to each other to switch to the pre-installed state. At this time, the fastener 200 can be removed from the base plate 10.

[0048] Optionally, see Figure 3 In one specific embodiment, the end of the first fixing plate 11 away from the second fixing plate 12 forms a first fixing position 111, and the end of the second fixing plate 12 away from the first fixing plate 11 forms a second fixing position 121. When the base plate 10 is in a fixed state, the first fixing position 111 and the second fixing position 121 are engaged in the slots 2011 opened at opposite ends of the component to be fixed 200. When the base plate 10 is in a pre-installed state, at least one of the first fixing position 111 and the second fixing position 121 can move relative to the slots 2011 at opposite ends.

[0049] One end of the first fixing plate 11 is used as the first fixing position 111, and one end of the second fixing plate 12 is used as the second fixing position 121. In this case, the first fixing plate 11 and the second fixing plate 12 can be simple plate structures without any additional processing. Both the first mating part and the second mating part are slots 2011.

[0050] First, when the base plate 10 is in the pre-installed state, one end of the first fixing plate 11 is inserted into the slot 2011 of the first mating part, and one end of the second fixing plate 12 is aligned with the opening of the slot 2011 of the second mating part, or one end of both the first fixing plate 11 and the second fixing plate 12 are aligned with the opening of the corresponding slot 2011. At this time, the first mounting surface 112 and the second mounting surface 122 form an obtuse angle. Then, the component to be fixed 200 is controlled to exert force on the side closer to the base plate 10 so that the second fixing plate 12 is inserted into the slot 2011 of the second mating part, and the first fixing plate 11 is inserted into the slot 2011 of the first mating part. The first fixing plate 11 and the second fixing plate 12 are driven to move relative to each other until the first mounting surface 112 and the second mounting surface 122 are coplanar, and the base plate 10 is switched to the fixed state.

[0051] Furthermore, after the base plate 10 is in a fixed state, the locking member 30 can be fixed at one end to the first fixing plate 11 and at the other end to the second fixing plate 12 to lock the first fixing plate 11 and the second fixing plate 12.

[0052] If it is necessary to remove the component 200 to be fixed, at least one end of the locking member 30 is unlocked from the first fixing plate 11 or the second fixing plate 12. Then, the first fixing plate 11 and the second fixing plate 12 are rotated relative to each other so that the point where they are connected moves away from the component 200 to be fixed until the first fixing plate 11 and / or the second fixing plate 12 disengage from the slot 2011 of the component 200 to be fixed, thereby completing the disassembly.

[0053] In one embodiment, the first fixing plate 11 and the second fixing plate 12 can be directly rotatably connected, or a rotating shaft 14 can be provided between them. When the first fixing plate 11 and the second fixing plate 12 are subjected to force, they can rotate relative to the rotating shaft 14.

[0054] In one embodiment, see [reference] Figures 2 to 4 The mounting frame 100 also includes at least one limiting member 20. All the limiting members 20 are arranged at intervals along the first direction L1 on the base plate 10, and the first direction L1 and the second direction L2 are intersected.

[0055] The limiting member 20 is used to limit the fixed member 200 mounted on the base plate 10, preventing it from sliding along the first direction L1 after being assembled on the base plate 10. All the limiting members 20, the first assembly surface 112 and the second assembly surface 122 form a receiving space, which has an opening facing the assembly surface 10b. Understandably, the first fixing position 111 and the second fixing position 121 need to be connected to or located within the receiving space. When the fixed member 200 can enter the receiving space from the opening for pre-assembly, it can be directly movably connected to the first fixing position 111 or the second fixing position 121. Then, after the state of the base plate 10 is switched, it can be directly fastened to the base plate 10 through the first fixing position 111 and the second fixing position 121.

[0056] Specifically, the limiting member 20 may include one or more. When the limiting member 20 includes one, it may be disposed on either the first fixing plate 11 or the second fixing plate 12. When the limiting member 20 includes multiple, they are disposed at intervals along the first direction L1 on the base plate 10 and located on both sides of the member to be fixed 200, for limiting the member to be fixed 200.

[0057] In one embodiment, the limiting member 20 includes a first limiting block 211 and a second limiting block 212 disposed opposite to each other along the second direction L2. The first limiting block 211 is disposed on the first fixing plate 11, and the second limiting block 212 is disposed on the second fixing plate 12. Every two first limiting blocks 211 and second limiting blocks 212 disposed opposite to each other along the second direction L2 form a limiting group 21. At least two limiting groups 21 are arranged at intervals along the first direction L1 on the base plate 10.

[0058] Each set of limiting groups 21 limits the member 200 to be fixed from one side, and a member 200 to be fixed can be installed between every two sets of adjacent limiting groups 21. The distance between every two sets of adjacent limiting groups 21 in the first direction L1 can be limited according to the specific size of the member 200 to be fixed.

[0059] Furthermore, at least one limiting member 20 can be provided to be movable relative to the base plate 10, that is, any one of the first limiting block 211 and the second limiting block 212 can be moved relative to the base plate 10, so as to be applicable to the fixed member 200 of different sizes, volumes and shapes.

[0060] In one embodiment, see [reference] Figures 2 to 4 The locking component 30 includes a support rod 31, one end of which is mounted on the first fixing plate 11 and the other end is mounted on the second fixing plate 12 to lock the first fixing plate 11 and the second fixing plate 12, and at least one end of the support rod 31 is detachably connected.

[0061] After the first fixing plate 11 and the second fixing plate 12 rotate relative to each other until the first mounting surface 112 and the second mounting surface 122 are coplanar, the opposite ends of the support rod 31 are fixed to the first fixing plate 11 and the second fixing plate 12 respectively, thereby supporting and locking the first fixing plate 11 and the second fixing plate 12 and preventing them from continuing to rotate relative to each other. When it is necessary to unlock, one end of the support rod 31 can be removed from the base plate 10 or both ends can be removed from the base plate 10.

[0062] Furthermore, the limiting assembly 21 mentioned above can be used to install the support rod 31. In this case, the limiting assembly 21 not only limits the fixing part 200 but also allows for the installation of the support rod 31. For details, please refer to [link / reference needed]. Figures 2 to 5 At least one set of limiting blocks 211 and the second limiting block 212 in the limiting group 21 have a first mounting groove 2111 and a second mounting groove 2121 that are arranged opposite to each other in the second direction L2. One end of the support rod 31 is fitted into the first mounting groove 2111 and the other end is fitted into the second mounting groove 2121.

[0063] Since the first limiting block 211 is located on the first fixed plate 11 and the second limiting block 212 is located on the second fixed plate 12, one end of the support rod 31 is fitted into the first mounting groove 2111 of the first limiting block 211 and the other end is fitted into the second mounting groove 2121 of the second limiting block 212, thus achieving the support and fixation of the first fixed plate 11 and the second fixed plate 12.

[0064] When assembling the support rod 31, one end can be inserted into the first mounting groove 2111, and the other end into the second mounting groove 2121. Understandably, the distance between the first mounting groove 2111 and the second mounting groove 2121 in the second direction L2 is the length of the support rod 31. For convenient installation of the support rod 31, please refer to... Figure 6 At least one end of the support rod 31 includes an elastic segment 312, which can deform under stress.

[0065] Specifically, when one end of the support rod 31 has an elastic segment 312, the other end can be first inserted into one of the first mounting groove 2111 and the second mounting groove 2121, and then the elastic segment 312 can be pressed to allow it to enter the other of the first mounting groove 2111 and the second mounting groove 2121. Alternatively, one end of the elastic segment 312 can be first inserted into one of the first mounting groove 2111 and the second mounting groove 2121, and then the support rod 31 can be pressed from the end without the elastic segment 312, causing the elastic segment 312 to deform so that the end without the elastic segment 312 can be inserted into the other of the first mounting groove 2111 and the second mounting groove 2121.

[0066] Preferably, elastic sections 312 can be provided at both ends of the support rod 31 to facilitate the installation of the support rod 31.

[0067] In one embodiment, the support rod 31 includes a rod body 311 and an elastic segment 312 disposed at at least one end thereof. The elastic segment 312 includes a ball 3121 and an elastic portion 3122, which is elastically connected between the ball 3121 and the rod body 311.

[0068] The ball 3121 can rotate relative to the elastic section 312. During the assembly process of the support rod 31, the elastic part 3122 is elastically deformed by pressing the ball 3121, thereby changing the length of the support rod 31. After the support rod 31 is assembled, the ball 3121 at at least one end of the support rod 31 abuts against the groove wall of the first mounting groove 2111 and / or the second mounting groove 2121.

[0069] The elastic part 3122 can be a common elastic structure such as a helical spring, and this application does not limit it.

[0070] Furthermore, the mounting frame 100 of this application may include multiple sets of limiting groups 21, and each set of limiting groups 21 may be equipped with a support rod 31. The limiting group 21 is used not only to limit the fixed part 200, but also to limit the support rod 31.

[0071] In one embodiment, the first fixing plate 11 and / or the second fixing plate 12 are provided with fixing holes 13. After the component to be fixed 200 is assembled on the base plate 10, additional fasteners can be inserted into the fixing holes 13 and the mounting frame 100 can be installed in a set position to realize the assembly of the component to be fixed 200.

[0072] The mounting frame 100 provided in this application can quickly and easily install and remove the components 200 to be fixed, such as circuit breakers and air compressor switches, and improve operational efficiency.

[0073] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0074] The above embodiments merely illustrate several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
