Description

Technical Field

[0001] This utility model relates to the field of air conditioning equipment technology, and in particular to a panel mounting structure. Background Technology

[0002] In the design of outdoor units of multi-split central air conditioning systems, the outdoor unit panel is usually large and heavy, and the panel is generally installed on the front side of the casing frame using screws.

[0003] For example, Chinese utility model patent CN219243756U discloses an installation structure for a panel assembly and an outdoor unit / air conditioner. The panel assembly includes a lower rear panel and an upper rear panel, both of which are assembled to the rear crossbeam of the housing. The upper rear panel has a screw hole for a first screw to pass through, and a portion of the upper rear panel is pressed against the outside of the lower rear panel. The first screw passes through the screw hole to thread the lower rear panel to the rear crossbeam of the housing.

[0004] However, this screw fixing method has obvious shortcomings: maintenance personnel must remove and install each screw individually, a tedious and time-consuming process that results in low installation and maintenance efficiency and fails to meet users' needs for convenience. More importantly, due to the large size and heavy weight of the panel, if no one supports it during disassembly, the panel is very likely to suddenly fall when the last screw is removed, posing a serious safety hazard of injuring maintenance personnel, making it impractical. Utility Model Content

[0005] To address the technical problem of low disassembly and assembly efficiency in existing technologies, this utility model provides a panel mounting structure.

[0006] The technical solution adopted by this utility model to solve its technical problem is:

[0007] The panel mounting structure includes a panel and a mounting frame. The panel is detachably mounted on the front side of the mounting frame. Pin assemblies are provided on both the left and right sides of the panel. Each pin assembly includes a pin seat and a pin post. The pin seat is fixedly mounted on the panel, and the pin post is movably connected to the pin seat. The mounting frame has pin holes corresponding to the pin posts. The insertion direction of the pin post on the left side of the panel is at an angle to the insertion direction of the pin post on the right side of the panel, so that the panel is fixed on the mounting frame.

[0008] Furthermore, the insertion direction of the pin on the left side of the panel is horizontal to the right, while the insertion direction of the pin on the right side of the panel is horizontal to the back.

[0009] Furthermore, a groove is provided on the side of the pin holder facing the panel. The groove includes a first end face close to the panel, a second end face away from the panel, and a sidewall connecting the first and second end faces. A mating hole is provided on the second end face of the groove, extending through to the side of the pin holder away from the panel. The pin is inserted into the groove and the mating hole, with the first end of the pin extending out of the mating hole. An elastic element is provided on the pin. Pulling the first end of the pin can disengage the second end of the pin from the pin hole. Releasing the first end of the pin allows the second end of the pin to at least partially extend into the pin hole under the restoring action of the elastic element. The pin has a limiting part to prevent the first end of the pin from extending out of the mating hole at any time.

[0010] Furthermore, the elastic element is a compression spring, and a mounting part is provided between the first end and the second end of the pin, with the compression spring positioned between the mounting part and the second end face of the groove.

[0011] Furthermore, the limiting part is located at the first end of the pin, and the limiting part is a limiting block.

[0012] Furthermore, the pin includes a first mating section and a second mating section. The outer diameter of the first mating section is smaller than that of the second mating section. A step is formed at the junction of the first and second mating sections, which is the mounting part. A compression spring is sleeved on the first mating section. One end of the compression spring abuts against the second end face of the groove, and the other end of the compression spring abuts against the step.

[0013] Furthermore, the second mating section of the pin has an annular groove and also includes a retaining spring. The retaining spring is sleeved in the annular groove and is used to limit the travel of the pin when it contacts the panel.

[0014] Furthermore, there are hanging holes on both the left and right sides of the panel, and corresponding hooks are provided on the mounting frame, with the hanging holes and hooks cooperating with each other.

[0015] Furthermore, a handle is provided on the front side of the panel.

[0016] Furthermore, the handle is formed by the front surface of the panel being recessed to the rear to create a receiving space.

[0017] The beneficial effects of this utility model are:

[0018] This invention features pin assemblies on both the left and right sides of the panel, with corresponding pin holes on the mounting frame. The insertion direction of the pin on the left side of the panel forms an angle with that of the pin on the right side, thus securing the panel to the mounting frame. Disassembly and assembly are simple; the pins can be manually pulled out or inserted. Compared to traditional techniques that require tools to remove and install screws one by one, this invention reduces the difficulty of disassembly and assembly, saving maintenance time.

[0019] In addition, the panel is equipped with a handle and hanging holes, and the mounting frame has corresponding hooks. During installation, the panel is first hung on the mounting frame before the fasteners are installed, making installation easier and less difficult. During disassembly, even if all the fasteners are removed, the panel is still hung on the mounting frame, solving the problem of the panel easily falling off during disassembly and improving safety.

Detailed Implementation

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the present invention will be further described below with reference to the accompanying drawings.

[0031] First, it should be stated that the technical solutions of the embodiments of this application are clearly and completely described. The described embodiments are only some of the embodiments of this application, and not a limitation of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0032] In the description of this utility model, it should be understood that the terms "first", "second", "upper", "lower", "left", "right", "inner", "outer", "axial" or "radial" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing this utility model and are not intended to indicate or imply that the device or element referred to must have a specific orientation structure and operation. Therefore, they should not be construed as limitations on this utility model.

[0033] Reference Figures 1 to 9 This utility model provides a panel mounting structure.

[0034] like Figures 1 to 4 As shown, in some embodiments, a panel mounting structure is provided, including a panel 1 and a mounting frame 2. The panel 1 is detachably mounted on the front side of the mounting frame 2. A pin assembly 3 is provided on both the left and right sides of the panel 1. The pin assembly 3 includes a pin seat 31 and a pin post 32. The pin seat 31 is fixedly mounted on the panel 1, and the pin post 32 is movably connected to the pin seat 31. The mounting frame 2 has a pin hole 4 corresponding to the pin post 32. The insertion direction of the pin post 32 on the left side of the panel 1 is at an angle to the insertion direction of the pin post 32 on the right side of the panel 1, so that the panel 1 is fixed on the mounting frame 2.

[0035] Due to the presence of the included angle, panel 1 can be limited in the vertical, horizontal, and front-back directions. The included angle is greater than 0° and less than 180°. Options include 30°, 40°, 45°, 60°, 90°, 120°, or 150°. No particular limitation is made here, as long as panel 1 does not detach from the mounting frame 2 after installation.

[0036] like Figures 1 to 4 As shown, preferably, the insertion direction of the pin 32 on the left side of panel 1 forms a 90° angle with the insertion direction of the pin 32 on the right side of panel 1. That is, the insertion direction of the pin 32 on the left side of panel 1 is horizontal to the right, and the insertion direction of the pin 32 on the right side of panel 1 is horizontal to the rear. This arrangement provides a more balanced limitation of the pins 32 in terms of vertical, horizontal, and forward / backward movement of panel 1, resulting in a more stable structure. Figure 5 As shown, preferably, two latch assemblies 3 are provided on both the left and right sides of panel 1.

[0037] The pin 32 can be inserted and reset manually, or it can be inserted by the elastic force of the elastic element. This embodiment does not make any special limitations, as long as the pin 32 can be inserted into and detached from the pin hole 4.

[0038] For the pin 32 to be movably connected to the pin seat 31, it is sufficient to ensure that the pin 32 can move relative to the pin seat 31. It can be a sliding connection, for example, the pin seat 31 is provided with a guide groove, and the pin 32 fits into the guide groove, or a guide rail sliding connection can be provided, or it can be an elastic connection. Of course, there are other movable connections that can be realized, which will not be listed here.

[0039] like Figures 2 to 4 As shown, when installing panel 1, push panel 1 from front to back. Due to the presence of the guide slope 16, the compression spring 7 will slowly contract, and the pin 32 will also contract, making it easier to push in. After the pin 32 is pushed into place, the pin 32 will be inserted into the pin hole 4 of the mounting frame 2. The hanging hole 13 of panel 1 is hooked onto the hook 14 of the mounting frame 2, and the entire panel 1 is installed. When disassembling panel 1, simply hold the first end of the pin 32 and pull it outward. The pin 32 will disengage from the pin hole 4. Lift panel 1 upward, and the hanging hole 13 will disengage from the hook 14, thus completing the disassembly of panel 1.

[0040] Another installation method is to attach the hanging hole 13 of the panel 1 to the hook 14 of the mounting frame 2. At this time, pull the first end of the pin 32 outward. When the second end of the pin 32 is aligned with the pin hole 4, release the first end of the pin 32 and insert the second end of the pin 32 into the pin hole 4.

[0041] like Figures 6 to 8 As shown, for the pin assembly 3, a commonly used pin assembly 3 can be used. As a preferred embodiment, the pin seat 31 has a groove 5 on the side facing the panel 1. The groove 5 includes a first end face close to the panel 1, a second end face away from the panel 1, and a side wall connecting the first end face and the second end face. The second end face of the groove 5 has a mating hole 6, which extends to the side of the pin seat 31 away from the panel 1. The pin post 32 passes through the groove 5 and the mating hole 6. The first end of the pin post 32 extends out of the mating hole 6. The pin post 32 is provided with an elastic element. Pulling the first end of the pin post 32 can disengage the second end of the pin post 32 from the pin hole 4. Releasing the first end of the pin post 32 can allow the second end of the pin post 32 to at least partially extend into the pin hole 4 under the reset action of the elastic element. The pin post 32 has a limiting part to prevent the first end of the pin post 32 from extending out of the mating hole 6 at any time.

[0042] Preferably, the elastic element on the pin 32 is a compression spring 7. A mounting portion is provided between the first and second ends of the pin 32. The compression spring 7 is positioned between the mounting portion and the second end face of the groove 5. When the first end of the pin 32 is pulled, the compression spring 7 is compressed, allowing the second end of the pin 32 to disengage from the pin hole 4. When the first end of the pin 32 is released, the second end of the pin 32, under the restoring action of the compression spring 7, at least partially extends into the pin hole 4. Alternatively, a tension spring can be used. A mounting portion is provided between the first and second ends of the pin 32. The tension spring is positioned between the mounting portion and the panel 1. When the first end of the pin 32 is pulled, the tension spring is stretched, allowing the second end of the pin 32 to disengage from the pin hole 4. When the first end of the pin 32 is released, the second end of the pin 32, under the restoring action of the tension spring, at least partially extends into the pin hole 4.

[0043] The pin holder 31 is fixed on the panel 1, and can be fixed by welding, screws, bolts or snap-fit.

[0044] like Figures 6 to 9 As shown, the mounting portion can be a limiting protrusion or an annular protrusion provided between the first and second ends of the pin 32. Preferably, the mounting portion is located near the second end of the pin 32 to ensure that the pin 32 has sufficient length to cooperate with the elastic element and serve as the force point of the elastic element. In a preferred embodiment, the elastic element is a compression spring 7. The pin 32 includes a first mating section 8 and a second mating section 9. The outer diameter of the first mating section 8 is smaller than the outer diameter of the second mating section 9. A step 10 is formed at the junction of the first mating section 8 and the second mating section 9. The step 10 is the mounting portion. The compression spring 7 is sleeved on the first mating section 8. One end of the compression spring 7 abuts against the second end face of the groove 5, and the other end of the compression spring 7 abuts against the step 10.

[0045] The elastic element can be a compression spring, a tension spring, or an elastic rubber block.

[0046] like Figures 6 to 9 As shown, when the elastic element is positioned between the mounting portion and the second end face of the groove 5, the force exerted by the elastic element should act on both the mounting portion and the second end face of the groove 5. When the elastic element is a compression spring 7, the compression spring 7 can be directly sleeved on the pin 32, or a mounting structure can be provided on the pin 32, and a guide post can be provided on the second end face of the groove 5. Both the mounting structure and the compression spring 7 are sleeved on the guide post. The compression spring 7 is parallel to the length direction of the pin 32. One end of the compression spring 7 abuts or connects to the mounting structure, and the other end abuts or connects to the second end face of the groove 5.

[0047] like Figures 6 to 9As shown, the limiting part is designed to prevent the first end of the pin 32 from extending out of the mating hole 6 at any time, thus ensuring that the worker can access the first end of the pin 32 at any time and perform disassembly or installation work, and preventing the first end of the pin 32 from extending into the pin seat 31. The limiting part can be a limiting block provided at the first end of the pin 32, with the outer contour of the limiting block at least partially outside the mating hole 6 to ensure that the limiting block does not enter the mating hole 6; the limiting part can also be an annular groove 11 provided on the second mating section 9 of the pin 32, and a retaining spring 12 provided, which is sleeved in the annular groove 11. When the second end of the pin 32 extends into the pin hole 4, the retaining spring 12 contacts the panel 1 to ensure that the pin 32 does not completely enter the pin hole 4, and the first end of the pin 32 still extends out of the mating hole 6, for limiting the stroke of the pin 32; it can be a limiting protrusion or an annular protrusion provided between the first end and the second end of the pin 32, with the limiting part and the mounting part arranged side by side and spaced apart along the length direction of the pin 32; it can be the mounting part in the aforementioned embodiment, which can serve as the limiting part in this embodiment.

[0048] like Figure 3 and Figure 5 As shown, to enhance safety during the installation and removal of panel 1, in some embodiments, hanging holes 13 are provided on both the left and right sides of panel 1, and corresponding hooks 14 are provided on the mounting frame 2. The hanging holes 13 and hooks 14 cooperate with each other. During installation, panel 1 is first hung on the mounting frame 2 before the fasteners are installed, making installation easier and less difficult. During removal, even if all fasteners are removed, panel 1 remains hung on the mounting frame 2, solving the problem of panel 1 easily falling off during removal and improving safety. Of course, the arrangement of hanging holes 13 and hooks 14 can be adjusted flexibly, i.e., hooks 14 can be provided on panel 1, and hanging holes 13 can be provided on the mounting frame 2.

[0049] like Figure 5 As shown, in order to make it easier to install and remove the panel 1, a handle 15 is provided on the front side of the panel 1. The handle 15 can be a common handle or a protrusion. As a preferred embodiment, the handle 15 is recessed from the front surface of the panel 1 to the rear to form a receiving space. The setting of the receiving space makes the panel 1 more beautiful. At the same time, the setting of the receiving space makes it easy for people to reach in and exert force.
