Description

Technical Field

[0001] The present invention relates to the technical field of level measurement, and specifically to a measuring device for assisting in the horizontal installation of air conditioners. Background Art

[0002] Air conditioners are one of the essential electrical appliances in people's lives in the hot summer. Since condensate water is generated during the use of the indoor unit of the air conditioner, during installation, most rely on the personal experience of the installer, without pre-measuring the levelness of the installation position. The angle cannot be accurate. If the installation angle is too large or too small, the left and right sides of the indoor unit of the air conditioner will be unbalanced, easily causing the position of the side where the drain pipe is led out to be too high, resulting in drainage difficulties, and thus the phenomenon of water dripping from the indoor unit of the air conditioner. The water will drip indoors, causing the indoor floor to be wet, which not only affects the indoor environment but may also cause damage due to moisture on the ground. Therefore, a measuring device for assisting in the horizontal installation of air conditioners is designed here to solve the above problems. Summary of the Invention

[0003] The purpose of the present invention is to provide a measuring device for assisting in the horizontal installation of air conditioners to solve the problems raised in the above background art.

[0004] To achieve the above purpose, the present invention provides the following technical solution: A measuring device for assisting in the horizontal installation of air conditioners includes a support plate and a support column. An articulated block is fixed at the middle position of the bottom end of the support plate, and an articulated seat is fixed at the upper end of the support column. The articulated seat and the articulated block are hinged to each other. The support plate is used to lift the indoor unit of the air conditioner to be installed to the installation position, and then, according to the orientation of the water outlet of the indoor unit of the air conditioner, the articulated block at the bottom end of the support plate is rotated around the position hinged to the articulated seat to adjust the balance of the left and right sides of the indoor unit of the air conditioner on the support plate, so as to prevent the position of the side where the drain pipe is led out from being too high, resulting in drainage difficulties, causing water to drip from the indoor unit of the air conditioner, and causing the indoor floor to be wet, which not only affects the indoor environment but may also cause damage due to moisture on the ground.

[0005] A pin shaft with a half-cylindrical structure is rotatably provided at the bottom side of the articulated seat. An angle scale with a half-cylindrical structure is fixed at the end of the pin shaft. A pointer that can point to the scale line of the angle scale is vertically fixed at the side of the middle position of the bottom end of the support plate. When the support plate is flipped, the pointer flips simultaneously with the support plate. Since the angle scale has a half-cylindrical structure, when the articulated seat cannot be kept in the vertical direction, the angle scale will automatically flip through the pin shaft, so that its zero scale line is always in the vertical direction and does not affect the accuracy of the value indicated by the end of the pointer on the angle scale.

[0006] The outer wall bottom end of the support column symmetrically fixes two T-shaped sliders. The outer walls of the T-shaped sliders are slidably provided with adjusting cross bars. The two adjusting cross bars are arranged in parallel. And the ends of the two adjusting cross bars are both fixed with lapping blocks in an inverted V-shaped structure. After the air conditioner indoor unit is placed on the support plate, lift the support plate upward and adjust the positions of the adjusting cross bars on the two T-shaped sliders according to the shoulder width of the staff, that is, adjust the gap between the two adjusting cross bars. Seat the two lapping blocks in an inverted V-shaped structure on the shoulders of the staff, and use the strength of the body to assist in lifting the support plate upward, and free up both hands to facilitate the balance adjustment of the support plate around the flipping position of the hinge seat.

[0007] In a further embodiment, a threaded rod is rotatably provided at the bottom end of the support column, and a hollow sleeve is slidably sleeved on the outer wall of the threaded rod.

[0008] The top end of the radial side wall of the hollow sleeve is fixed with an adjusting sleeve. The connection between the adjusting sleeve and the hollow sleeve is communicated with each other, and a threaded column is rotatably provided at the communication part. The threaded column is in threaded connection with the outer wall of the threaded rod. An annular rotating groove is opened on the radial side wall of the threaded column. An adjusting rod is rotatably inserted into the adjusting sleeve. The end of the adjusting rod extends into the annular rotating groove. An annular limiting groove is opened on the outer wall of the end of the adjusting rod. The top wall of the annular rotating groove is provided with tooth blocks distributed along the edge of the groove. The tooth blocks match the limiting groove. By matching the tooth blocks with the limiting groove, when the adjusting rod rotates, the threaded column can rotate synchronously. At the same time, when the threaded column rotates, it can drive the threaded rod to axially adjust along the adjusting sleeve by using the external thread, so as to facilitate the lifting and lowering of the threaded rod, and the threaded rod is restricted by the external thread and will not drop randomly.

[0009] In a further embodiment, a hollow sleeve is rotatably provided at the end of the adjusting rod, and the hollow sleeve is rotatably sleeved on the outer wall of the annular rotating groove.

[0010] In a further embodiment, a hollow cavity is provided in the support column. Two openings are symmetrically opened on the radial side wall of the support column. Two arc-shaped adjusting plates are slidably provided in the two openings respectively. Two arc-shaped sliders are symmetrically slidably provided on the inner wall of the hollow cavity, and the two arc-shaped sliders are respectively fixedly connected with the two arc-shaped adjusting plates. Hinge rods are respectively hinged between the upper ends of the two arc-shaped adjusting plates and the two sides of the bottom end face of the support plate.

[0011] In a further embodiment, a fastening sleeve is threadedly connected to the outer wall of the support column. The inner wall of the fastening sleeve is threadedly connected to the outer walls of two arc-shaped adjusting plates. The outer threads of the two arc-shaped adjusting plates have opposite helix directions. By rotating the fastening sleeve, the position can be adjusted up and down along the outer wall of the support column. When the fastening sleeve is screwed onto the outer walls of the two arc-shaped adjusting plates, due to the opposite helix directions of the outer threads of the two arc-shaped adjusting plates, as the fastening sleeve rotates continuously, the two arc-shaped adjusting plates can be adjusted in opposite directions, that is, when one arc-shaped adjusting plate is adjusted upward, the other arc-shaped adjusting plate is adjusted downward. The arc-shaped slider abuts against the inner wall of the hollow cavity of the support column to prevent the arc-shaped adjusting plate from falling off from the opening. Through the corresponding hinge rod, the hinge block at the bottom end of the support plate can be pulled to rotate unidirectionally around the hinge position with the hinge seat.

[0012] In a further embodiment, an anti-detachment disk located below the fastening sleeve is fixed to the bottom end of the support column.

[0013] In a further embodiment, an installation groove is formed at the upper end of the support plate. A plurality of conveyor rollers are rotatably arranged between the left and right side walls in the installation groove, and the upper end of the radial side wall of the conveyor roller is higher than the height of the notch of the installation groove.

[0014] In a further embodiment, two adjustment through holes are formed on both sides of the support plate. The two through holes on the same side form a group and are located on the front and rear sides of the support plate. A limiting rod is slidably inserted into the adjustment through hole, and the limiting rod is in interference fit with the inside of the adjustment through hole. In this way, without external force, the limiting rod will not slide up and down randomly along the inner wall of the adjustment through hole. The upper end of the limiting rod extends out of the upper opening of the adjustment through hole to serve as a limiting member blocking the front and rear sides of the air conditioner indoor unit, avoiding the air conditioner indoor unit from slipping and being damaged during the process of lifting the air conditioner indoor unit.

[0015] In a further embodiment, a connecting rod located below the support plate is fixed between the bottom ends of the opposite side walls of the two front and rear limiting rods.

[0016] In a further embodiment, sliding grooves are formed on both side walls of the limiting rod, and clamping blocks slidably engaged with the sliding grooves are fixed to the inner wall of the adjustment through hole.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] The present invention relates to a measuring device for assisting in the horizontal installation of an air conditioner. The measuring device uses a support plate to lift the indoor unit of the air conditioner to be installed to the installation position, and then rotates the hinge block at the bottom of the support plate around the hinge position with the hinge seat, and the pointer flips synchronously for measurement operation. The angle scale automatically flips through the pin shaft, so that its zero scale line is always in the vertical direction. Therefore, the scale indicated by the pointer on the angle scale is the installation angle of the indoor unit of the air conditioner. The balance on the left and right sides of the indoor unit of the air conditioner located on the support plate is precisely adjusted to prevent the position of the side where the drain pipe is led out from being too high, resulting in difficult drainage, causing the indoor unit of the air conditioner to drip water, and causing the indoor floor to be wet, which not only affects the indoor environment, but also may cause damage due to moisture on the ground.

Detailed implementation mode

[0030] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0031] Embodiment. This embodiment provides a measuring device for assisting in the horizontal installation of an air conditioner, including a support plate 1 and a support column 3. An articulated block is fixed at the middle position of the bottom end of the support plate 1, and an articulated seat 2 is fixed at the upper end of the support column 3. The articulated seat 2 and the articulated block are articulated with each other, as Figure 1 and Figure 2 shown. Use the support plate 1 to lift the indoor unit of the air conditioner to be installed to the installation position, and then rotate the articulated block at the bottom end of the support plate 1 around the articulated position with the articulated seat 2 according to the orientation of the water outlet of the indoor unit of the air conditioner, so as to adjust the balance on the left and right sides of the indoor unit of the air conditioner on the support plate 1, preventing the position on the side where the drain pipe is led out from being too high, causing drainage difficulties, resulting in water dripping from the indoor unit of the air conditioner, and causing the indoor ground to be wet, which not only affects the indoor environment, but also may cause damage to the ground due to moisture.

[0032] When rotating the support plate 1 to adjust the balance on the left and right sides of the indoor unit of the air conditioner without any reference, there are certain errors. Although the installation of the indoor unit of the air conditioner does not belong to precision installation, if the installation inclination is too large, it also affects the aesthetics. Therefore, in order to accurately solve the problem of the flipping angle of the support plate 1, a pin shaft with a half-cylindrical structure is rotatably provided at the bottom side of the articulated seat 2, and an angle scale 8 with a half-cylindrical structure is fixed at the end of the pin shaft. A pointer 7 that can point to the scale line of the angle scale 8 is vertically fixed at the side position of the middle position of the bottom end of the support plate 1. Since the angle scale 8 is a half-cylindrical structure, when the articulated seat 2 cannot be kept in the vertical direction, the angle scale 8 will automatically flip through the pin shaft, so that its zero scale line is always in the vertical direction, and it will not affect the accuracy of the value indicated by the end of the pointer 7 on the angle scale 8.

[0033] When the support plate 1 flips, the pointer 7 flips simultaneously with the support plate 1, and the pointer 7 flips synchronously for measurement operation. That is to say, regardless of whether the articulated seat 2 is in the numerical direction, the angle scale 8 flips around the pin shaft, its zero scale line is in the vertical direction, and the position where the deflected end of the pointer 7 is located is the inclination angle of the indoor unit of the air conditioner, avoiding poor measurement accuracy caused by external factors.

[0034] The staff only needs to refer to the angle value indicated by the end of the pointer 7 deviating from the zero scale line on the angle scale 8, which is the deflection angle of the indoor unit of the air conditioner. The measurement is fast and convenient. Usually, the deflection angle is about within 1-5°.

[0035] When installing the indoor unit of the air conditioner, it is necessary to lift the indoor unit of the air conditioner to a certain height until it reaches the preset installation hole position. In this process, the method adopted in the prior art is that the staff manually lift it with force, which is quite laborious. Therefore, two T-shaped sliders 4 are symmetrically fixed at the bottom end of the outer wall of the support column 3. An adjusting cross bar 5 is slidably arranged on the outer wall of the T-shaped slider 4. The two adjusting cross bars 5 are arranged in parallel with each other, and inverted V-shaped structure lapping blocks 6 are fixed at the ends of the two adjusting cross bars 5. As Figure 1 shown, after placing the indoor unit of the air conditioner on the support plate 1, lift the support plate 1 upward, and adjust the position of the adjusting cross bar 5 on the two T-shaped sliders 4 according to the shoulder width of the staff, that is, adjust the gap between the two adjusting cross bars 5, so as to place the inverted V-shaped structure lapping blocks 6 on the shoulders of the staff, use the strength of the body to assist in lifting the support plate 1 upward, and free both hands to facilitate the balance adjustment of the support plate 1 around the flipping position with the hinge seat 2.

[0036] An installation groove is opened at the upper end of the support plate 1. A plurality of conveying rollers 11 are rotatably arranged between the left and right side walls in the installation groove. The upper end of the radial side wall of the conveying roller 11 is higher than the height of the installation groove opening. As Figure 8 shown, when the support plate 1 lifts the indoor unit of the air conditioner to the installation position, the indoor unit of the air conditioner can be slid on the plurality of conveying rollers 11 from the side close to the staff to the side close to the installation position by pushing the indoor unit of the air conditioner, saving the physical strength of the staff.

[0037] Adopting the method of using the body to assist in lifting the indoor unit of the air conditioner upward can assist in quickly lifting the indoor unit of the air conditioner to the installation position. However, during installation, it is difficult to ensure that the height of the indoor unit of the air conditioner does not change. Further, a threaded rod 9 is rotatably arranged at the bottom end of the support column 3. A hollow sleeve 10 is slidably sleeved on the outer wall of the threaded rod 9. As Figure 3 shown, lift the threaded rod 9 along the inside of the hollow sleeve 10. The hollow sleeve 10 stands on the ground, so as to assist in stably supporting the support plate 1 from floating up and down in height, so as to prevent the position of the indoor unit of the air conditioner from changing in the vertical direction, resulting in the misalignment of the installation hole position and affecting the quick installation of the indoor unit of the air conditioner.

[0038] A regulating sleeve 101 is fixed at the top end of the radial side wall of the hollow sleeve 10. The connection between the regulating sleeve 101 and the hollow sleeve 10 is mutually communicated, and a threaded column 103 is rotatably arranged at the communication part. The threaded column 103 is threadedly connected with the outer wall of the threaded rod 9. An annular rotating groove is opened on the radial side wall of the threaded column 103. A regulating rod 102 is rotatably inserted into the regulating sleeve 101. The end of the regulating rod 102 extends into the annular rotating groove. An annular structure limiting groove is opened on the outer wall of the end of the regulating rod 102. Tooth blocks are arranged on the top wall of the annular rotating groove along the edge position of the groove. The tooth blocks are matched with the limiting groove. As Figure 6 and Figure 7As shown, by matching the tooth block with the limit groove, when the adjusting rod 102 rotates, the threaded column 103 can rotate synchronously. At the same time, when the threaded column 103 rotates, it can drive the threaded rod 9 to axially adjust along the adjusting sleeve 101 by using the external thread, so as to facilitate the lifting of the threaded rod 9. Moreover, the threaded rod 9 is restricted by the external thread and will not drop randomly.

[0039] A hollow sleeve 104 is rotatably provided at the end of the adjusting rod 102. The hollow sleeve 104 is rotatably sleeved on the outer wall of the annular rotating groove, and the hollow sleeve 104 can prevent the adjusting rod 102 from falling off.

[0040] A hollow cavity is provided inside the support column 3. Two openings are symmetrically formed on the radial side wall of the support column 3. Two arc-shaped adjusting plates 33 are slidably provided in the two openings. Two arc-shaped sliders 35 are symmetrically slidably provided on the inner wall of the hollow cavity, and the two arc-shaped sliders 35 are respectively fixedly connected to the two arc-shaped adjusting plates 33. Hinge rods 34 are hinged between the upper ends of the two arc-shaped adjusting plates 33 and the two sides of the bottom end face of the support plate 1. A fastening sleeve 32 is threadedly connected to the outer wall of the support column 3, and the inner wall of the fastening sleeve 32 is threadedly connected to the outer walls of the two arc-shaped adjusting plates 33. The external threads of the two arc-shaped adjusting plates 33 have opposite helix directions. As Figure 3 、 Figure 4 and Figure 5 shown, by rotating the fastening sleeve 32, its position can be adjusted up and down along the outer wall of the support column 3. When the fastening sleeve 32 is screwed onto the outer walls of the two arc-shaped adjusting plates 33, due to the opposite helix directions of the external threads of the two arc-shaped adjusting plates 33, as the fastening sleeve 32 rotates continuously, the two arc-shaped adjusting plates 33 can be adjusted in opposite directions, that is, when one arc-shaped adjusting plate 33 moves upward, the other arc-shaped adjusting plate 33 moves downward. The arc-shaped slider 35 abuts against the inner wall of the hollow cavity of the support column 3 to prevent the arc-shaped adjusting plate 33 from falling off from the opening. Through the corresponding hinge rod 34, the hinge block at the bottom end of the support plate 1 can be pulled to rotate unidirectionally around the hinge position with the hinge seat 2.

[0041] The opposite adjustment of the two arc-shaped adjusting plates 33 can quickly adjust the balance of the left and right sides of the air conditioner indoor unit, and the support plate 1 will not be randomly flipped around the hinge position due to the lack of limiting components, resulting in the air conditioner indoor unit falling and being damaged.

[0042] An anti-drop plate 31 is fixed at the bottom end of the support column 3 below the fastening sleeve 32 to prevent the fastening sleeve 32 from falling off.

[0043] Furthermore, two adjustment through holes are formed on both sides of the support plate 1. The two through holes on the same side are in a group and are located on the front and rear sides of the support plate 1. A limiting rod 12 is slidably inserted into the adjustment through hole. As Figure 9 and Figure 10As shown, the limiting rod 12 is in an interference fit with the inside of the adjustment through-hole, so that the limiting rod 12 will not slide up and down randomly along the inner wall of the adjustment through-hole without external force. The upper end of the limiting rod 12 extends out of the upper opening of the adjustment through-hole to serve as a limiting member that blocks the front and rear sides of the indoor unit of the air conditioner, preventing the indoor unit of the air conditioner from slipping and being damaged during the process of lifting the indoor unit of the air conditioner.

[0044] After the indoor unit of the air conditioner is lifted to the installation position, all the limiting rods 12 are slid downward along the inside of the adjustment through-hole to prevent the upper ends of the limiting rods 12 from protruding out of the upper opening of the adjustment through-hole, which facilitates the horizontal sliding of the indoor unit of the air conditioner for installation. In order to quickly slide the limiting rods 12 along the inside of the adjustment through-hole, a connecting rod 121 located below the support plate 1 is fixed between the bottom ends of the opposite side walls of the two relatively front and rear limiting rods 12. The staff can pull down the two connecting rods 121 with both hands to synchronously slide the four limiting rods 12 downward along the inside of the adjustment through-hole, improving the adjustment efficiency of the limiting rods 12.

[0045] In addition, sliding grooves are formed on both side walls of the limiting rod 12, and clamping blocks that are slidably clamped with the sliding grooves are fixed on the inner wall of the adjustment through-hole. By slidably clamping the clamping blocks with the sliding grooves, the limiting rod 12 is prevented from being pulled out of the bottom opening of the adjustment through-hole.

[0046] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
