[0002] In the field of aero-engines, engine casings typically have multiple mounting points. These mounting points are used to secure various components such as air lines and test sensors. Threaded bushings are usually fixed to these mounting points for connecting these components. Commonly used bushing structures have inner and outer threads. The outer thread is used to secure the bushing assembly, while the inner thread is used to connect air line flanges, test sensors, and other components. However, threaded bushing structures have the following problems:

[0003] First, special tools are needed to screw the threaded insert in order to install and remove it, and the installation and removal process is quite cumbersome.

The sleeve portion is provided in the base hole portion and is arranged sequentially with the stop portion of the retaining ring in a direction away from the bottom of the mounting hole. The limiting lug portion is provided in the limiting hole portion to restrict the rotation of the threaded sleeve around its own axis.

[0012] Optionally, the limiting holes are arranged in pairs along the diameter direction of the mounting hole, and the limiting lugs correspond one-to-one with the limiting holes; the base hole and the limiting holes are interconnected along the diameter direction of the mounting hole.

[0013] Optionally, the retaining ring has a flexible opening.

[0014] Optionally, a first limiting flange is provided on the outer periphery of the retaining ring, at least a portion of which extends to one of the paired limiting holes; a second limiting flange is provided on the outer periphery of the retaining ring, at least a portion of which extends to the other of the paired limiting holes.

[0015] Secondly, the present invention discloses a housing including a mounting bracket assembly.

[0016] Thirdly, the present invention discloses an assembly method for a mounting base assembly, applicable to a mounting base assembly, the method comprising:

[0017] Step S100: Perform the flexible component assembly process, including:

[0018] Connect the retaining ring to the elastic element;

[0019] The connecting rod is passed through the retaining ring so that the retaining cover is positioned opposite to the side of the retaining ring connected to the elastic element;

[0020] Step S200: Perform the threaded sleeve assembly process, including:

[0021] Connect the connecting rod to the bottom of the receiving hole so that the retaining ring is limited between the threaded sleeve and the retaining cover.

[0022] Step S400: Perform the threaded sleeve assembly process, including:

[0023] With the bottom of the threaded sleeve facing the bottom of the mounting hole, insert the threaded sleeve together with the elastic component into the mounting hole;

[0024] Step S600: Perform the circlip pressing process, including:

[0025] Press the threaded sleeve to a height less than the groove;

[0026] Insert the retaining ring into the retaining slot;

[0027] Release the threaded sleeve so that it abuts against the retaining ring.

[0028] The beneficial effects of this invention are as follows:

[0029] This application discloses a mounting base assembly, comprising: a mounting base with a mounting hole, the peripheral surface of which is smooth and has a groove; a retaining ring, the connecting portion of which is located in the groove, and the stopping portion of which extends into the mounting hole; a threaded sleeve disposed in the mounting hole, the outer peripheral surface of which is smooth, and the threaded sleeve and the stopping portion of the retaining ring being arranged sequentially in a direction away from the bottom of the mounting hole; and an elastic component disposed in the mounting hole, the elastic component being elastically supported between the threaded sleeve and the mounting base so that the threaded sleeve abuts against the retaining ring.

[0030] Compared with related technologies, the mounting bracket assembly of the present invention can improve the efficiency of disassembly and assembly. The following describes the effect of this technology in conjunction with the disassembly and assembly process of the mounting bracket assembly of the present invention:

[0031] When assembling the mounting bracket assembly, first insert the threaded sleeve into the mounting hole with the bottom of the threaded sleeve facing the bottom of the mounting hole; then press the retaining ring into the retaining groove to achieve axial positioning of the threaded sleeve.

[0032] When the mounting bracket assembly needs to be disassembled, first separate the retaining ring from the retaining groove and remove the retaining ring from the mounting hole to release the axial restriction on the threaded sleeve; then pull the threaded sleeve out of the mounting hole to separate the threaded sleeve from the mounting bracket.

[0033] It can be seen that the structure of the mounting base assembly has been improved in the embodiments of the present invention. Specifically, the mounting base assembly in the related art adopts a connection method of "the external thread of the threaded sleeve is connected to the threaded hole of the mounting base", while the mounting base assembly of the present invention adopts a connection method of "setting the peripheral surface of the mounting hole and the outer peripheral surface of the threaded sleeve to be smooth, and using a retaining ring to limit the axial movement of the threaded sleeve".

[0034] In the first aspect, during the assembly and disassembly of the mounting base assembly of the present invention, the threaded sleeve can be inserted or removed from the mounting base by inserting or pulling, thereby avoiding the need for special tools to screw the threaded sleeve for assembly and disassembly in related technologies, thus reducing tool usage. In the second aspect, compared with the threaded sleeve screwing method in related technologies, the insertion and pulling method of the threaded sleeve in the embodiment of the present invention can better ensure the smooth assembly and disassembly of the mounting base assembly and improve the assembly and disassembly efficiency. In the third aspect, since the mounting base and the threaded sleeve have a smooth surface contact, it can avoid damage to the thread surface caused by screwing during the assembly and disassembly process, thereby reducing the replacement frequency of related parts of the mounting base assembly, improving the service life of related parts, and ensuring the reliability of subsequent use. In the fourth aspect, compared with the threaded sleeve screwing method in related technologies, the smooth surface contact and fit between the mounting base and the threaded sleeve in the present invention allows for a certain installation gap, making it more convenient to fix and install various components such as air pipeline flanges and test sensors.

[0035] The elastic component is configured such that when the retaining ring is separated from the mounting base and moved out of the mounting hole, the elastic component can drive at least a portion of the threaded sleeve to extend out of the mounting hole, for example, the elastic component only pushes the top of the threaded sleeve out of the mounting hole, or the elastic component pushes the entire threaded sleeve out of the mounting hole.

[0036] After the mounting bracket assembly is assembled, the retaining ring will compress the elastic component through the threaded sleeve, so that the elastic component stores elastic potential energy. When the mounting bracket assembly needs to be disassembled, the retaining ring is removed from the mounting bracket, and the elastic component will restore its deformation, so that at least part of the threaded sleeve driven by the elastic component extends out of the mounting bracket, thereby facilitating the removal of the threaded sleeve from the mounting hole. This can further improve the disassembly efficiency of the mounting bracket assembly and simplify the disassembly action. Attached Figure Description

[0064] The present invention will be further described below with reference to specific embodiments and accompanying drawings. More details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention can obviously be implemented in many other ways different from those described herein. Those skilled in the art can make similar extensions and derivations based on actual application situations without departing from the spirit of the present invention. Therefore, the scope of protection of the present invention should not be limited by the content of this specific embodiment.

[0065] It should be noted that these and other accompanying drawings are merely examples and are not drawn to scale, and should not be construed as limiting the scope of protection of the present invention.

[0066] In related technologies, engine casings are equipped with mounting seats, and threaded sleeves are installed in the mounting seats to connect various components. Common threaded sleeve structures have inner and outer threads. The outer thread is used to fix the sleeve to the mounting seat assembly, while the inner thread is used to connect various components such as air line flanges and test sensors. However, this requires special tools to tighten the threaded sleeve for installation and removal, making the process cumbersome. Furthermore, the threads are prone to structural damage during installation and removal, and in subsequent use, leading to inconvenience and low reliability. Therefore, to solve these problems, the technical solution of this invention was developed. The following describes the invention in conjunction with... Figures 1 to 11 To elaborate.

[0067] This invention discloses a mounting base assembly, which includes a mounting base 10, a retaining ring 20, and a threaded sleeve 30. The mounting base 10 can be... Figure 1 The housing mounting base shown is a column structure protruding from the outer ring surface of the housing 1. The cross-section of the mounting base 10 is rectangular, but it can also be other shapes. The mounting base 10 and the housing 1 are integrated to ensure the overall structural strength. Figure 8 This is a structural diagram of the mounting base of the present invention. The mounting base 10 is provided with a mounting hole 101, which is a blind hole to achieve axial positioning of the threaded sleeve 30. The peripheral surface of the mounting hole 101 is a smooth surface, and the peripheral surface of the mounting hole 101 is provided with a groove 102, which is an annular groove provided along the circumference of the mounting hole 101.

[0068] like Figure 2 , Figure 3 and Figure 8 As shown, the retaining ring 20 is disposed in the mounting hole 101. Specifically, the connecting part of the retaining ring 20 is located in the retaining groove 102, and the stopping part of the retaining ring 20 extends into the mounting hole 101 to achieve the fixation of the retaining ring 20 along the axial direction of the mounting hole 101.

[0069] A threaded sleeve 30 is disposed in the mounting hole 101. The outer circumferential surface of the threaded sleeve 30 is smooth. The stop portions of the threaded sleeve 30 and the retaining ring 20 are arranged sequentially in a direction away from the bottom of the mounting hole 101, that is, the threaded sleeve 30 and the retaining ring 20 are arranged sequentially in a direction away from the housing 1. In this way, the retaining ring 20 achieves axial limiting of the threaded sleeve 30, so that the threaded sleeve 30 is limited between the retaining ring 20 and the bottom surface of the mounting hole 101. The top surface of the threaded sleeve 30 faces the retaining ring 20, and the bottom surface of the threaded sleeve 30 faces the bottom surface of the mounting hole 101. A first threaded hole 301 is provided on the top of the threaded sleeve 30. The first threaded hole 301 has an opening located on the top surface of the threaded sleeve 30, so that the first threaded hole 301 can be connected to various components such as air pipes and test sensors.

[0070] Compared with related technologies, the mounting bracket assembly of the present invention can improve the efficiency of disassembly and assembly. The following describes the effect of this technology in conjunction with the disassembly and assembly process of the mounting bracket assembly of the present invention:

[0071] When assembling the mounting bracket assembly, first insert the threaded sleeve 30 into the mounting hole 101 with the bottom of the threaded sleeve 30 facing the bottom of the mounting hole 101; then press the retaining ring 20 into the retaining groove 102 to achieve axial positioning of the threaded sleeve 30.

[0072] When the mounting bracket assembly needs to be disassembled, first separate the retaining ring 20 from the retaining groove 102 and remove the retaining ring 20 from the mounting hole 101 to release the axial restriction on the threaded sleeve 30; then pull the threaded sleeve 30 out of the mounting hole 101 to separate the threaded sleeve 30 from the mounting bracket 10.

[0073] It can be seen that the structure of the mounting base assembly has been improved in the embodiments of the present invention. Specifically, the mounting base assembly in the related art adopts a connection method of "the external thread of the threaded sleeve is connected to the threaded hole of the mounting base", while the mounting base assembly of the present invention adopts a connection method of "setting the peripheral surface of the mounting hole 101 and the outer peripheral surface of the threaded sleeve 30 to be smooth, and axially limiting the threaded sleeve 30 by the retaining ring 20".

[0074] In the first aspect, during the assembly and disassembly of the mounting base assembly of the present invention, the threaded sleeve 30 can be inserted into or removed from the mounting base 10 by inserting or pulling, thereby avoiding the need for special tools to tighten the threaded sleeve for assembly and disassembly as in related technologies, thus reducing tool usage. In the second aspect, compared with the threaded sleeve tightening method in related technologies, the insertion and pulling method of the threaded sleeve 30 in the embodiment of the present invention can better ensure the smooth assembly and disassembly of the mounting base assembly and improve the assembly and disassembly efficiency. In the third aspect, since the mounting base 10 and the threaded sleeve 30 have a smooth surface contact, it can avoid damage to the thread surface caused by thread tightening during the assembly and disassembly process, thereby reducing the replacement frequency of related parts of the mounting base assembly, improving the service life of related parts, and ensuring the reliability of subsequent use. In the fourth aspect, compared with the threaded sleeve tightening method in related technologies, the smooth surface contact and fit between the mounting base 10 and the threaded sleeve 30 in the present invention can provide a certain installation gap, which is more convenient for fixing and installing various components such as air pipeline flanges and test sensors.

[0075] Optionally, such as Figures 2-4 As shown, the mounting assembly also includes an elastic component 40, which is disposed in the mounting hole 101 and located at the bottom of the threaded sleeve 30, wherein the bottom of the threaded sleeve 30 is close to the bottom of the mounting hole 101. The elastic component 40 is elastically supported between the threaded sleeve 30 and the mounting base 10 so that the threaded sleeve 30 abuts against the retaining ring 20. The elastic component 40 is configured such that when the retaining ring 20 is separated from the mounting base 10 and moved out of the mounting hole 101, the elastic component 40 can drive at least a portion of the threaded sleeve 30 to extend out of the mounting hole 101. For example, the elastic component 40 may push only the top of the threaded sleeve 30 out of the mounting hole 101, or the elastic component 40 may push the entire threaded sleeve 30 out of the mounting hole 101.

[0076] After the mounting base assembly is assembled, the retaining ring 20 will compress the elastic component 40 through the threaded sleeve 30, so that the elastic component 40 stores elastic potential energy. When the mounting base assembly needs to be disassembled, the retaining ring 20 is removed from the mounting base 10. At this time, the elastic component 40 will restore its deformation, so that the elastic component 40 drives at least a part of the threaded sleeve 30 to extend outside the mounting base 10, thereby facilitating the removal of the threaded sleeve 30 from the mounting hole 101. This can further improve the disassembly efficiency of the mounting base assembly and simplify the disassembly action.

[0077] Optionally, regarding the specific structure of the elastic component 40, the elastic component 40 can be an elastic pad disposed at the bottom of the threaded sleeve 30. However, to ensure the effective ejection of the threaded sleeve 30 during disassembly, the elastic component 40 of the mounting base assembly of the present invention is configured with the following structure:

[0078] like Figures 4-7As shown, the elastic component 40 includes a limiting member 41, a retaining ring 42, and an elastic member 43. The limiting member 41 includes a connecting rod portion 411 and a cover portion 412. The first end of the connecting rod portion 411 is detachably connected to the bottom of the threaded sleeve 30, and the second end of the connecting rod portion 411 extends toward the bottom of the mounting hole 101. The cover portion 412 is disposed at the second end of the connecting rod portion 411.

[0079] The retaining ring 42 is movably fitted onto the connecting rod portion 411 and is confined between the threaded sleeve 30 and the cover portion 412. An elastic element 43 is fixed to the side of the retaining ring 42 facing the bottom of the mounting hole 101. For example, the elastic element 43 is welded to the retaining ring 42, and the elastic element 43 is elastically supported between the bottom of the threaded sleeve 30 and the bottom of the hole in the mounting base 10. The elastic element 43 can be a spring, and a limiting element 41 is fitted onto the elastic element 43. Thus, in the first aspect, the limiting effect of the limiting element 41 ensures the connection stability between the elastic component 40 and the threaded sleeve 30; in the second aspect, the separation or installation of the limiting element 41 and the threaded sleeve 30 facilitates the removal or installation of the elastic component 40 onto the threaded sleeve 30.

[0080] Optionally, a special area can be reserved between the threaded sleeve 30 and the bottom of the mounting hole 101 to accommodate the elastic component 40. To improve the compactness of the mounting assembly, the present invention adopts the following structure:

[0081] like Figure 3 and Figure 5 As shown, the bottom of the threaded sleeve 30 is provided with a receiving hole 302. The first end of the connecting rod part 411 is connected to the bottom of the receiving hole 302. For example, the limiting member 41 is a bolt, the connecting rod part 411 is the threaded part of the bolt, and the cover part 412 is the bolt head. The bottom of the receiving hole 302 is provided with a second threaded hole 303. The first end of the connecting rod part 411 is threaded to the second threaded hole 303 to realize the detachable connection between the limiting member 41 and the threaded sleeve 30. At the same time, the side of the cover part 412 facing away from the connecting rod part 411 can be provided with a flat groove 413 or a cross groove. In this way, the limiting member 41 can be screwed with a screwdriver or other tools, thereby better realizing the detachable connection between the limiting member 41 and the threaded sleeve 30. The limiting member 41 can also be configured with other structures, such as the connecting rod part 411 being an optical axis, and the bottom of the receiving hole 302 being provided with a matching insertion hole for the connecting rod part 411, with the connecting rod part 411 being interference-fitted in the insertion hole, which will not be described in detail here.

[0082] The elastic member 43 causes the retaining ring 42 to abut against the bottom of the receiving hole 302, thereby allowing at least a portion of the elastic component 40 to be received in the receiving hole 302, improving the compactness and space utilization of the mounting assembly and facilitating the miniaturization of the mounting assembly.

[0083] Optionally, the length of the elastic member 43 in its naturally extended state is greater than the depth of the receiving hole 302; the distance between the cover portion 412 and the bottom of the receiving hole 302 is less than the depth of the receiving hole 302. That is, the limiting member 41 will be entirely housed in the receiving hole 302, and the limiting member 41 will not have any part protruding outside the receiving hole 302.

[0084] After the mounting bracket assembly is assembled, on the one hand, the installation interference of the limiting member 41 can be avoided, so that the retaining ring 20 can effectively press the threaded sleeve 30 into place; on the other hand, the elastic member 43 can be free from the interference of the limiting member 41, so as to ensure that the elastic member 43 is fully compressed.

[0085] Optionally, such as Figure 3 As shown, the cover portion 412 satisfies: 2mm ≤ h1 ≤ 5mm; for example, h1 = 2mm, 4mm, 5mm, etc., where h1 is the distance between the end face of the cover portion 412 away from the connecting rod portion 411 and the bottom surface of the threaded sleeve 30. If the value of h1 is too small, the cover portion 412 will be too close to the bottom surface of the threaded sleeve 30, and interference from the limiting member 41 cannot be fully avoided. If the value of h1 is too large, the limiting member 41 will be screwed too deeply and will be difficult to disassemble and assemble. Therefore, the above values ​​are set to balance anti-interference and easy disassembly performance.

[0086] Optionally, the elastic element 43 satisfies: 5mm ≤ T ≤ 10mm; for example, T = 5mm, 6mm, 8mm, 10mm, etc., where T is the compression amount of the elastic element 43 after it is installed into the mounting base assembly. If the compression amount of the elastic element 43 is too small, the threaded sleeve 30 will not have enough extension relative to the mounting hole 101 during the disassembly process of the mounting base assembly, and the disassembly efficiency will not be significantly improved. If the compression amount of the elastic element 43 is too large, the external force required to compress the elastic element 43 during the assembly process of the mounting base assembly will be too large, increasing the assembly difficulty. Therefore, the above values ​​are selected to balance disassembly efficiency and assembly convenience.

[0087] Optionally, such as Figure 3 As shown, the retaining ring 42 and the connecting rod 411 satisfy the condition: 0.3mm ≤ a2 ≤ 0.5mm, for example, a2 = 0.3mm, 0.4mm, 0.5mm, etc., where a2 is the single-sided clearance between the inner hole of the retaining ring 42 and the connecting rod 411, that is, the difference between the radius of the inner hole of the retaining ring 42 and the radius of the connecting rod 411. If the value of a2 is too small, it will be difficult to assemble the retaining ring 42 and the connecting rod 411; if the value of a2 is too large, the retaining ring 42 will have a large radial wobble after assembly. Therefore, the above values ​​are selected to reduce the assembly difficulty and control the degree of wobble of the retaining ring 42.

[0088] Optionally, such as Figure 3As shown, the retaining ring 20 satisfies the following condition: 0.5mm ≤ h2 ≤ 2mm, for example, h2 = 0.5mm, 1mm, 1.5mm, 2mm, etc., where h2 is the gap value between the retaining groove 102 and the retaining ring 20 along the depth direction of the mounting hole 101, that is, the difference between the groove width of the retaining groove 102 and the thickness of the retaining ring 20. If h2 is too small, the gap between the retaining groove 102 and the retaining ring 20 will be too small, which is not conducive to the installation of the retaining ring 20. If h2 is too large, the retaining ring 20 will have large axial wobble. Therefore, according to the above values, it is convenient for the retaining ring 20 to be installed into the retaining groove 102 while reducing the wobble of the retaining ring 20.

[0089] Optionally, such as Figure 4 As shown, the retaining ring 20 satisfies the following condition: 0.3mm ≤ a1 ≤ 1mm, for example, a1 = 0.3mm, 0.5mm, 0.7mm, 1mm, etc., where a1 is the single-sided gap value between the retaining groove 102 and the retaining ring 20 along the diameter direction of the mounting hole 101, that is, the difference between the radius of the retaining groove 102 and the radius of the retaining ring 20. If a1 is too small, the gap between the retaining groove 102 and the retaining ring 20 will be too small, which is not conducive to the installation of the retaining ring 20. If a1 is too large, the retaining ring 20 will have a large radial wobble. Therefore, according to the above values, it is convenient to install the retaining ring 20 into the retaining groove 102 while controlling the wobble of the retaining ring 20.

[0090] Optionally, such as Figure 4 As shown, the threaded sleeve 30 satisfies: 2mm≤h3≤10mm, for example, h3=2mm, 5mm, 7mm, 10mm, etc., where h3 is the gap value between the bottom surface of the threaded sleeve 30 and the bottom surface of the mounting hole 101. If h3 is too small, it will be difficult to install the retaining ring 20 into the retaining groove 102. If h3 is too large, the threaded sleeve 30 will wobble significantly along the axial direction. Therefore, the above values ​​are selected to ensure that the retaining ring 20 is easy to install while the threaded sleeve 30 is not easy to wobble.

[0091] Optionally, such as Figure 2 , Figure 4 and Figure 8 As shown, the mounting hole 101 includes a base hole portion 103 and a limiting hole portion 104 that are interconnected. The slot 102 is provided on the circumferential surface of the hole in the base hole portion 103, and the stop portion of the retaining ring 20 extends into the base hole portion 103.

[0092] like Figure 4 , Figure 8 and Figure 9As shown, the threaded sleeve 30 includes a sleeve portion 31 and a limiting lug portion 32 connected to each other. The sleeve portion 31 is provided in the base hole portion 103, and the sleeve portion 31 and the stop portion of the retaining ring 20 are arranged sequentially in a direction away from the bottom of the mounting hole 101. The limiting lug portion 32 is provided in the limiting hole portion 104. The stop engagement between the limiting lug portion 32 and the limiting hole portion 104 restricts the rotation of the threaded sleeve 30 around its own axis, thereby improving the fixing effect of the threaded sleeve 30 in the mounting base 10.

[0093] Optionally, the limiting hole 104 can be located at the bottom of the base hole 103, and the limiting lug 32 can be a protrusion protruding from the bottom surface of the sleeve 31; or, the limiting lug 32 can be a key tooth protruding from the circumferential surface of the sleeve 31, and the limiting hole 104 can be a keyway located on the circumferential surface of the base hole 103. All of the above arrangements can restrict the rotation of the threaded sleeve 30 along its own axial direction. The present invention employs the following arrangement:

[0094] like Figure 8 As shown, the limiting hole portion 104 is arranged in pairs along the diameter direction of the mounting hole 101, and the base hole portion 103 and the limiting hole portion 104 are interconnected along the diameter direction of the mounting hole 101. Figure 9 As shown, the limiting lugs 32 are located on both sides of the sleeve portion 31 and are arranged in pairs along the axial diameter direction of the threaded sleeve 30. The limiting lugs 32 correspond one-to-one with the limiting holes 104. This design can further prevent the threaded sleeve 30 from rotating.

[0095] Optionally, such as Figure 2 , Figure 8 and Figure 9 As shown, the limiting hole portion 104 includes a straight groove section and an arc-shaped groove section arranged sequentially along the direction away from the base hole portion 103; the limiting support portion 32 includes a straight plate section and an arc-shaped section arranged sequentially along the direction away from the sleeve portion 31. The straight plate section of the limiting support portion 32 is accommodated in the straight groove section of the limiting hole portion 104, and the arc-shaped section is accommodated in the arc-shaped groove section. The planar fit between the straight plate section and the straight groove section is more conducive to limiting.

[0096] The limiting lug 32 satisfies the following condition: 0.5mm ≤ b1 ≤ 2mm, where b1 is the single-sided gap between the straight groove section of the limiting hole 104 and the straight plate section of the limiting lug 32, which is half the difference between the width of the straight groove section of the limiting hole 104 and the width of the straight plate section of the limiting lug 32. If b1 is too small, it will be difficult to disassemble and assemble the threaded sleeve 30 with the mounting base 10; if b1 is too large, the threaded sleeve 30 will have a large rotation angle in the mounting base 10. Therefore, the above values ​​are selected to control the rotation amplitude of the threaded sleeve 30 while disassembling and assembling it.

[0097] Optionally, such as Figure 11As shown, the retaining ring 20 is an elastic retaining ring with an elastic opening 201. This allows the elastic deformation of the retaining ring 20 to change the size of the elastic opening 201, thereby achieving elastic contraction of the retaining ring 20. The elastic contraction of the retaining ring 20 makes it easier to insert and remove the retaining ring 20 from the retaining groove 102.

[0098] Optionally, such as Figure 2 , Figure 8 and Figure 11 As shown, a first limiting flange 21 is provided on the outer periphery of the retaining ring 20. At least a portion of the first limiting flange 21 extends to one of the paired limiting holes 104. The first limiting flange 21 is provided in pairs on both sides of the elastic opening 201, and the elastic opening 201 corresponds to one of the paired limiting holes 104. A second limiting flange 22 is provided on the outer periphery of the retaining ring 20. At least a portion of the second limiting flange 22 extends to the other of the paired limiting holes 104. This facilitates fixing the retaining ring 20 and prevents the retaining ring 20 from rotating after assembly.

[0099] Optionally, the retaining ring 20 satisfies the condition 0.5mm≤b1≤2mm, where b1 is the single-sided gap between the second limiting flange 22 and the limiting hole 104, i.e., half the difference between the width of the second limiting flange 22 and the width of the limiting hole 104. If b1 is too small, it will be difficult to assemble and disassemble the retaining ring 20 with the mounting base 10; if b1 is too large, the retaining ring 20 will have a large rotation angle on the mounting base 10. Therefore, the above values ​​are selected to control the rotation amplitude of the retaining ring 20 while assembling and disassembling it.

[0100] Optionally, the inner circumference of the retaining ring 20 is provided with a mounting flange 23, which is symmetrically arranged on both sides of the elastic opening 201. The mounting flange 23 is provided with a tool hole 202. This allows tools such as tweezers to be inserted into the tool hole 202 to facilitate the application of external force to the retaining ring 20, thereby achieving elastic contraction of the retaining ring 20 and facilitating the installation and removal of the retaining ring 20 from the retaining groove 102.

[0101] like Figure 1 As shown, the present invention also discloses a housing, including the aforementioned mounting base assembly. The mounting base 10 is a housing mounting base protruding from the outer circumferential surface of the housing 1, and multiple mounting base assemblies can be arranged along the outer circumferential surface of the housing 1.

[0102] The present invention also discloses an assembly method for a mounting base assembly, applied to the above-mentioned mounting base assembly, the method comprising:

[0103] Step S100: Perform the flexible component assembly process, including:

[0104] The first end face of the retaining ring 42 is connected to the elastic element 43 by welding or other methods;

[0105] The connecting rod portion 411 passes through the retaining ring 42 so that the retaining cover portion 412 is positioned opposite to the first end face of the retaining ring 42.

[0106] Step S200: Perform the threaded sleeve assembly process, including:

[0107] The elastic component 40 is installed into the receiving hole 302, specifically by screwing the connecting rod part 411 into the second screw hole 303 so that the connecting rod part 411 is connected to the bottom of the receiving hole 302, and the cover part 412 is positioned opposite to the bottom of the receiving hole 302, with the retaining ring 42 limited between the threaded sleeve 30 and the cover part 412.

[0108] Step S300: Perform the elastic element extension measurement procedure, including:

[0109] Check whether the length of the elastic element 43 in its natural extended state is greater than the depth of the receiving hole 302. If not, replace the elastic element 43 with one of a different length.

[0110] Check whether the limiting member 41 is completely submerged in the receiving hole 302, and use a measuring tool to check whether the distance between the cover part 412 and the bottom surface of the threaded sleeve 30 meets the first preset distance h1; if the limiting member 41 has a part extending out of the receiving hole 302, or the distance between the cover part 412 and the bottom surface of the threaded sleeve 30 does not meet the first preset distance h1, then adjust the distance between the cover part 412 and the bottom of the receiving hole 302, for example, by continuing to screw the connecting rod part 411 into the second screw hole 303, or by replacing the limiting member 41 with one of other length specifications.

[0111] Step S400: Perform the threaded sleeve assembly process, including:

[0112] With the bottom of the threaded sleeve 30 facing the bottom of the mounting hole 101, the threaded sleeve 30 together with the elastic component 40 is inserted into the mounting hole 101.

[0113] Step S500: Perform the threaded sleeve extension inspection process, including:

[0114] At this time, the elastic element 43 is in a naturally extended state, so at least part of the threaded sleeve 30 extends out of the mounting hole 101. Check whether the size of the threaded sleeve 30 extending out of the mounting hole 101 meets the preset extension amount. The preset extension amount is the compression amount T of the elastic element 43. If not, remove the threaded sleeve 30 and disassemble the elastic component 40. After replacing the elastic element 43 with another length specification, repeat step S100.

[0115] Step S600: Perform the circlip pressing process, including:

[0116] Use tweezers or other tools to reach into the tool hole 202 to pick up the retaining ring 20 to the top surface of the thread sleeve 30;

[0117] An external force is applied along the width direction of the elastic opening 201 by tweezers to cause the retaining ring 20 to elastically contract;

[0118] By applying axial external force with tweezers, the threaded sleeve 30 is pressed into a height less than the groove 102, and the retaining ring 20 is aligned radially with the groove 102, that is, the top surface of the threaded sleeve 30 is below the groove 102, at which time the elastic component 40 is compressed.

[0119] The tweezers release the external force along the width of the elastic opening 201. At this time, the retaining ring 20 restores its elastic deformation and is inserted into the retaining groove 102.

[0120] The tweezers release the axial external force and separate from the retaining ring 20. At this time, the wire sleeve 30 is released, and the elastic component 40 drives the wire sleeve 30 to rise so that the wire sleeve 30 abuts against the retaining ring 20.

[0121] The disassembly method for the mounting bracket assembly is the reverse of the assembly method. Specifically, the disassembly method includes:

[0122] Step B100: Insert tweezers or other tools into the tool hole 202 to apply external force to cause the retaining ring 20 to elastically contract and separate from the retaining groove 102; then use tweezers to remove the retaining ring 20 from the mounting hole 101. At this time, the retaining ring 20 releases its stop on the threaded sleeve 30, the elastic component 40 will restore its elastic deformation, and the elastic component 40 will drive the threaded sleeve 30 to rise so that at least a portion of the threaded sleeve 30 extends out of the mounting hole 101.

[0123] Step B200: Pick up the part of the threaded sleeve 30 that extends out of the mounting hole 101 by hand or by using a tool, and then remove the threaded sleeve 30 together with the elastic component 40 from the mounting hole 101.

[0124] Step B300: Twist the connecting rod 411 to the second screw hole 303 to separate the limiting member 41 from the threaded sleeve 30, and then remove the limiting member 41, the retaining ring 42, and the elastic member 43 from the receiving hole 302.

Any variations and modifications can be made by those skilled in the art without departing from the spirit and scope of the invention. Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention, without departing from the scope of the invention, fall within the protection scope defined by the claims of the present invention.
