Abstract
Description
Technical Field
[0001] This utility model relates to the field of air conditioning equipment technology, and in particular to a beam mounting structure. Background Technology
[0002] In the design of multi-split central air conditioning outdoor units, the motor crossbeam is typically installed horizontally between two parallel lower crossbeams. The motor crossbeam is horizontally positioned along the front-to-back direction, while the lower crossbeams are horizontally positioned along the left-to-right direction. The motor crossbeam has first mounting holes at both ends, and the corresponding lower crossbeams have second mounting holes; the two are connected by screws.
[0003] For example, Chinese utility model patent with publication number CN207515094U discloses a motor bracket and an outdoor air conditioner unit. The motor bracket includes two brackets and two crossbeams. The two brackets are spaced apart, and the two ends of the two crossbeams are respectively connected to the two brackets. The cross-sectional shape of the crossbeams in the width direction is U-shaped. The crossbeams are used to connect the motor. The two ends of the crossbeams are provided with connection holes, and screws are inserted in the connection holes for connection with the brackets.
[0004] The standard installation procedure is as follows: first, assemble the motor and fan onto the motor crossbeam; then, hoist this assembly above the lower crossbeam; align the first and second mounting holes, and secure it with screws or bolts. However, in actual installation, the first and second mounting holes are often difficult to align quickly, requiring workers to make multiple adjustments, which significantly reduces installation efficiency. Utility Model Content
[0005] To address the technical problem of low installation efficiency in existing technologies, this utility model provides a beam installation structure.
[0006] The technical solution adopted by this utility model to solve its technical problem is:
[0007] The crossbeam mounting structure includes a motor crossbeam and two lower crossbeams arranged side by side and spaced apart. The motor crossbeam is horizontally arranged in the front-to-back direction, and the lower crossbeams are horizontally arranged in the left-to-right direction. The motor crossbeam overlaps between the two lower crossbeams. The motor crossbeam is provided with a first connecting hole at each end, and the lower crossbeams are provided with a corresponding second connecting hole, so that the first connecting hole and the second connecting hole are aligned for bolts or screws to be inserted.
[0008] At least one lower crossbeam has a first limiting member, and at least one side of the left and right walls of the motor crossbeam contacts the first limiting member to restrict the unilateral or bilateral movement of the motor crossbeam in the left-right direction.
[0009] At least one lower crossbeam has a second limiting member, and at least one end face of the front end face and the rear end face of the motor crossbeam contacts the second limiting member to restrict the single or double movement of the motor crossbeam in the front-rear direction.
[0010] When the motor beam contacts the first limiting member and the second limiting member simultaneously, the first connecting hole and the second connecting hole are aligned.
[0011] Furthermore, each of the two lower crossbeams has a first limiting member, and the left side wall of the motor crossbeam contacts the first limiting member to restrict the motor crossbeam from moving to the left. Each of the two lower crossbeams also has a second limiting member, and the front and rear faces of the motor crossbeams contact the second limiting member to restrict the motor crossbeam from moving forward and backward.
[0012] Furthermore, the lower crossbeam includes a first strip plate and a second strip plate connected to each other. The first strip plate is horizontally arranged, and the second strip plate is vertically arranged. The two lower crossbeams are arranged opposite each other, with the first strip plates of the two lower crossbeams close to each other and the second strip plates of the two lower crossbeams far from each other. The bottom wall of the motor crossbeam is in contact with the upper surface of the first strip plate. The surface of the second strip plate facing the motor crossbeam is the first surface, and the surface of the second strip plate away from the motor crossbeam is the second surface. At least one of the front end face and the rear end face of the motor crossbeam is in contact with the first surface of the second strip plate. The second strip plate constitutes a second limiting member. The upper surface of the first strip plate or the first surface of the second strip plate has a limiting protrusion, which constitutes a first limiting member.
[0013] Furthermore, the first connecting hole is located on the front and rear faces of the motor crossbeam, and the second connecting hole is located on the second strip plate.
[0014] Furthermore, a portion of the second surface of the second strip plate is recessed, and the corresponding position of the first surface is raised. The length of the raised area is 70% to 95% of the length of the second strip plate, and the second connecting hole is provided on the raised area.
[0015] Furthermore, the upper side of the second strip plate has multiple upwardly extending first legs, which are arranged at intervals along the length of the second strip plate.
[0016] Furthermore, the upper side of the second strip plate has a bent edge.
[0017] Furthermore, it also includes reinforcing ribs, which are connected to the upper surface of the first strip plate and the first surface of the second strip plate.
[0018] Furthermore, the lower side of the second strip plate has a second leg extending downwards.
[0019] Furthermore, the second strip plate is provided with hooks and first mounting holes on both the left and right sides, and also includes a bracket for installing the lower crossbeam. The bracket is provided with corresponding grooves and second mounting holes. The hooks of the second strip plate are hooked into the grooves, and the first mounting holes and second mounting holes are aligned for screws or bolts to pass through and fix them.
[0020] The beneficial effects of this utility model are:
[0021] This invention uses a first limiting member to restrict the unilateral or bilateral movement of the motor crossbeam in the left-right direction, and a second limiting member to restrict its unilateral or bilateral movement in the front-back direction. When the motor crossbeam is hoisted onto the lower crossbeam, the worker only needs to push the assembly horizontally until it simultaneously contacts the first and second limiting members. At this point, the first and second connecting holes automatically and precisely align, and installation is completed by fixing with bolts or screws.
[0022] This design completely solves the shortcomings of traditional installation methods. When heavy components such as motors and fans are assembled onto the motor beam, the entire assembly becomes bulky and difficult to handle. In traditional techniques, workers need to repeatedly adjust the left-right and front-back positions visually to align the holes. Due to the lack of a two-way positioning reference, multiple trials are often required, consuming a lot of time and energy. This utility model relies on the physical positioning and guiding function of the first and second limiting components to quickly align the first and second connecting holes, improving installation efficiency, significantly reducing labor intensity, and eliminating safety hazards.

[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.

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.

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 6 This utility model provides a crossbeam mounting structure.
[0034] like Figure 1 As shown, in some embodiments, a crossbeam mounting structure is provided, including a motor crossbeam 1 and two lower crossbeams 2 arranged side by side and spaced apart. The motor crossbeam 1 is arranged horizontally in the front-back direction, and the lower crossbeams 2 are arranged horizontally in the left-right direction. The motor crossbeam 1 overlaps between the two lower crossbeams 2. The motor crossbeam 1 is provided with a first connecting hole 3 at both ends, and the lower crossbeams 2 are provided with a second connecting hole 4, so that the first connecting hole 3 and the second connecting hole 4 are aligned for bolts or screws to pass through.
[0035] At least one lower crossbeam 2 has a first limiting member, and at least one side of the left side wall and the right side wall of the motor crossbeam 1 contacts the first limiting member to restrict the single or double movement of the motor crossbeam 1 in the left and right directions.
[0036] At least one lower crossbeam 2 has a second limiting member, and at least one end face of the front end face and the rear end face of the motor crossbeam 1 contacts the second limiting member to restrict the single or double movement of the motor crossbeam 1 in the front-rear direction.
[0037] When the motor beam 1 contacts the first limiting member and the second limiting member at the same time, the first connecting hole 3 and the second connecting hole 4 are aligned.
[0038] For the first connecting hole 3 and the second connecting hole 4, one of them can be a screw through hole and the other is a threaded hole. After the tail of the screw passes through the screw through hole, it is threadedly connected to the threaded hole, and the head of the screw presses against the motor crossbeam 1 or the lower crossbeam 2. Alternatively, both can be bolt through holes. The bolt is inserted into the bolt through hole and the bolt is tightened to fix the motor crossbeam 1 and the lower crossbeam 2.
[0039] like Figures 1 to 3 As shown, the first limiting member can be a limiting protrusion 7 on the lower crossbeam 2; it can also be a protruding structure formed by a stamping process; or a local area of the lower crossbeam 2 can be stamped to form a flip-up piece. The first limiting members on both lower crossbeams 2 can be located on the left side of the motor crossbeam 1, with the first limiting member contacting the left side wall of the motor crossbeam 1, restricting the motor crossbeam 1 from moving to the left; the first limiting members on both lower crossbeams 2 can be located on the right side of the motor crossbeam 1, with the first limiting member contacting the right side wall of the motor crossbeam 1, restricting the motor crossbeam 1 from moving to the right; the first limiting members on both lower crossbeams 2 can be located on the left and right sides of the motor crossbeam 1, with the first limiting member contacting the left and right side walls of the motor crossbeam 1, restricting the motor crossbeam 1 from moving to the left and right; alternatively, one of the first limiting members on the lower crossbeam 2 can be located on both the left and right sides of the motor crossbeam 1, with the first limiting member contacting the left and right side walls of the motor crossbeam 1, restricting the motor crossbeam 1 from moving to the left and right. The left and right walls of beam 1 are in contact. The first limiting member on the other lower crossbeam 2 is set on the left or right side of motor crossbeam 1, and the first limiting member is in contact with the left or right wall of motor crossbeam 1. Alternatively, the first limiting member can be set on one of the lower crossbeams 2, in contact with the left or right wall of motor crossbeam 1, while the other lower crossbeam 2 is not set with the first limiting member. This can also restrict the unilateral or bilateral movement of motor crossbeam 1 in the left and right directions. Alternatively, the first limiting member can be set on one of the lower crossbeams 2, in contact with the left and right walls of motor crossbeam 1, while the other lower crossbeam 2 is not set with the first limiting member. This can also restrict the bilateral movement of motor crossbeam 1 in the left and right directions.
[0040] like Figures 1 to 3 As shown, the second limiting member can be configured in the same way as the first limiting member, or the lower crossbeam 2 can be designed as follows: the lower crossbeam 2 includes a first strip plate 5 and a second strip plate 6 connected to each other. The first strip plate 5 is horizontally arranged, and the second strip plate 6 is vertically arranged. In this case, the second strip plate 6 serves as the second limiting member. Either the front end face or the rear end face of the motor crossbeam 1 can contact the second strip plate 6, which can restrict the unilateral movement of the motor crossbeam 1 in the front-to-back direction, i.e., restrict the motor crossbeam 1 to move forward or backward; alternatively, both the front end face and the rear end face of the motor crossbeam 1 can contact the second strip plate 6, which can restrict the bilateral movement of the motor crossbeam 1 in the front-to-back direction, i.e., restrict the motor crossbeam 1 to move forward and backward.
[0041] like Figures 1 to 3As shown, preferably, both lower crossbeams 2 have a first limiting member, and the left side wall of the motor crossbeam 1 contacts the first limiting member to restrict the leftward movement of the motor crossbeam 1. Both lower crossbeams 2 have a second limiting member, and the front and rear ends of the motor crossbeam 1 contact the second limiting member to restrict the forward and backward movement of the motor crossbeam 1. With this configuration, the motor crossbeam 1 is limited in the forward and backward direction. Simply push the motor crossbeam 1 to the left until the left side wall of the motor crossbeam 1 contacts the first limiting member. At this point, the motor crossbeam 1 is positioned, and the first connecting hole 3 and the second connecting hole 4 are perfectly aligned, making operation simpler.
[0042] like Figures 1 to 4 As shown, for the setting of the lower crossbeam 2, the lower crossbeam 2 can be designed as a conventional beam structure, or preferably, the lower crossbeam 2 includes a first strip plate 5 and a second strip plate 6 connected to each other. The first strip plate 5 is set horizontally, and the second strip plate 6 is set vertically. The two lower crossbeams 2 are set opposite to each other. The first strip plates 5 of the two lower crossbeams 2 are close to each other, and the second strip plates 6 of the two lower crossbeams 2 are far apart from each other. The bottom wall of the motor crossbeam 1 is in contact with the upper surface of the first strip plate 5. The surface of the second strip plate 6 facing the motor crossbeam 1 is the first surface, and the surface of the second strip plate 6 away from the motor crossbeam 1 is the second surface. At least one of the front end face and the rear end face of the motor crossbeam 1 is in contact with the first surface of the second strip plate 6. The second strip plate 6 constitutes a second limiting member. The upper surface of the first strip plate 5 or the first surface of the second strip plate 6 has a limiting protrusion 7, and the limiting protrusion 7 constitutes a first limiting member. With this design, there is no need to set up a second limiting component. The lower crossbeam 2 itself can be used as a second limiting component, such as the second strip plate 6. At least one of the front and rear faces of the motor crossbeam 1 is in contact with the first surface of the second strip plate 6. Preferably, both the front and rear faces of the motor crossbeam 1 are in contact with the first surface of the second strip plate 6. In this way, the motor crossbeam 1 is set between the two lower crossbeams 2. The front face of the motor crossbeam 1 is in contact with the first surface of the second strip plate 6 of one of the lower crossbeams 2, and the rear face of the motor crossbeam 1 is in contact with the first surface of the second strip plate 6 of the other lower crossbeam 2. This can restrict the forward and backward movement of the motor crossbeam 1. Simply push the motor crossbeam 1 to move in the left and right direction until the motor crossbeam 1 contacts the first limiting component to complete the positioning. The first connecting hole 3 and the second connecting hole 4 are just aligned.
[0043] like Figure 1 and Figure 5As shown, regarding the arrangement of the first connecting hole 3 and the second connecting hole 4, the first connecting hole 3 is located at the end of the motor crossbeam 1, which can be located on the bottom wall of the end, i.e., the motor crossbeam 1 rests on the lower crossbeam 2. The first connecting hole 3 on the bottom wall of the motor crossbeam 1 is aligned with the second connecting hole 4 on the lower crossbeam 2. Preferably, the first connecting hole 3 is located on the front and rear faces of the motor crossbeam 1, and the second connecting hole 4 is located on the second strip plate 6. This facilitates the installation of screws or bolts by workers, who only need to install and tighten the screws from front to back and from the outside to the inside, without needing to insert them into the mounting frame, making installation more convenient.
[0044] like Figures 1 to 3 As shown, to enhance the strength of the lower crossbeam 2, a portion of the second surface of the second strip plate 6 is recessed, while the corresponding position on the first surface is raised. This raised area 8 serves as a reinforcing structure, increasing the strength of the second strip plate 6. The length of the raised area 8 is 70% to 95% of the length of the second strip plate 6, for example, 70%, 80%, 85%, 90%, or 95%. Of course, multiple raised areas 8 can also be spaced along the length of the second strip plate 6. The length of a single raised area 8 is much smaller than the length of the second strip plate 6, while the combined length of multiple raised areas 8 is 70% to 95% of the length of the second strip plate 6. The second connecting hole 4 is provided on the raised area 8. Preferably, the top of the raised area 8 is a flat surface, so that the second connecting hole 4 can be aligned with the first connecting hole 3 on the front and rear faces of the motor crossbeam 1 and connected with screws.
[0045] like Figure 2 and Figure 3 As shown, the second strip plate 6 further has multiple upwardly extending first legs 9 on its upper side, and the multiple first legs 9 are arranged at intervals along the length direction of the second strip plate 6. The first legs 9 are used to install the air guide ring sleeved on the outside of the fan, directly supporting the air guide ring, and are used for the collection and guidance of the exhaust air from the fan, reducing additional fasteners and lowering assembly costs.
[0046] like Figure 2 and Figure 3 As shown, the second strip plate 6 further includes a bent edge 10 on its upper side, which is used to strengthen the structural strength of the second strip plate 6. The bending process forms an integrated reinforced structure, improving its resistance to deformation, making it particularly suitable for vibration or load-bearing scenarios without requiring additional material costs.
[0047] like Figure 2 and Figure 3As shown, furthermore, it also includes a reinforcing rib 11, which connects the upper surface of the first strip plate 5 and the first surface of the second strip plate 6. The first strip plate 5 and the second strip plate 6 can be assembled and fixed by welding, or they can be formed by bending. Thus, the reinforcing rib 11 is provided between the upper surface of the first strip plate 5 and the first surface of the second strip plate 6 to increase the structural strength. Regardless of whether it is welded or bent, the reinforcing rib 11 can compensate for the weak points at the connection, prevent cracking, reduce the fatigue risk at the connection, and extend the service life.
[0048] like Figure 5 As shown, the second strip plate 6 further has a downward-extending second leg 12 on its lower side. The core 18 is fixed to the frame composed of the lower crossbeam 2 and other components. Since the upper part of the core 18 is not fastened, it may tilt forward during actual transportation due to bumps and other factors, severely affecting its appearance. The second leg 12 can abut against the upper part of the outer surface of the core 18, effectively limiting the movement of the core 18 and preventing it from tilting forward.
[0049] like Figure 5 and Figure 6 As shown, the second strip plate 6 is further provided with hooks 13 and first mounting holes 14 on both its left and right sides, and also includes a bracket for installing the lower crossbeam 2. The bracket is provided with corresponding grooves 15 and second mounting holes 16. The hooks 13 of the second strip plate 6 are hooked into the grooves 15, and the first mounting holes 14 and second mounting holes 16 are aligned for screws or bolts to be inserted and fixed. The bracket can be a vertically installed column, or it can be a vertically installed left side panel 19 and right side panel 20 of the air conditioner. The lower crossbeam 2 is hooked into the grooves 15 by the hooks 13 to achieve the pre-positioning of the lower crossbeam 2. At this time, the worker does not need to keep lifting or pressing the lower crossbeam 2, and the worker can free up his hands to fix it with screws or bolts, improving installation efficiency. For the first mounting hole 14 and the second mounting hole 16, one of them can be a screw through hole and the other can be a threaded hole. The tail of the screw passes through the screw through hole and is threaded into the threaded hole, and the head of the screw presses against the bracket or the lower crossbeam 2. Alternatively, both can be bolt through holes, with the bolt passing through the bolt through hole and the bolt being tightened to fix the bracket and the lower crossbeam 2.
