Description

Technical Field

[0001] The utility model belongs to the technical field of air-conditioning repair tools, and in particular relates to an air-conditioning refrigerant filling and metering tool. Background Art

[0002] Existing air conditioning refrigerant (also known as refrigerant) is a substance that transfers heat within an air conditioning system by changing state. It absorbs heat in the evaporator, transforming from liquid to gas, thereby lowering the ambient temperature and achieving cooling. It then releases heat in the condenser, transforming back into liquid, completing a cycle. Typically, after a certain period of use, the refrigerant will gradually leak due to microscopic gaps in pipe connections, aging seals, or accidental damage. This requires repair and recharging, which often requires metering tools.

[0003] When measuring refrigerant, an electronic scale is usually used to determine the refrigerant filling amount by measuring the weight change of the refrigerant tank before and after filling. The weight of the refrigerant is equal to its density multiplied by the volume. When the refrigerant type is known (because different refrigerants have different densities), the filling volume can be converted by accurately measuring the weight. For example, for R410A refrigerant, its density is about 1.109g / cm3. When the electronic scale shows that 1109g of R410A refrigerant has been added, it is equivalent to adding 1 liter. And so on. During use, it is usually necessary to place the refrigerant tank on the electronic scale to stabilize it, then tare it, and then fill it. The calculation is based on the fixed data change of the electronic scale. Since the refrigerant tank itself may have a certain weight, the refrigerant tank will cause a momentary collision when placed on the scale. This impact may cause permanent deformation of the elastic element of the sensor, thereby affecting the performance of the scale. In addition, when the electronic scale is placed on an uneven surface, it may tilt, resulting in subsequent unstable and tilted measurements, affecting the accuracy of the measurement.

[0004] In view of this, the present utility model is proposed. Utility Model Content

[0005] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide an air-conditioning refrigerant charging and metering tool.

[0006] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is:

[0015] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described below at the same time:

[0016] 1. The utility model provides a carrying plate and a carrying tray, and can realize supporting both sides of the carrying tray by rotating the adjusting screw rod and pushing the carrying plate. When the refrigerant tank is placed on the upper side of the carrying tray, the carrying plate supports the carrying tray, so that the pressure during placement is offset by the carrying plate and will not be transmitted to the inside of the electronic scale body through the carrying tray. After the placement is stable, the carrying plate can be moved by rotating the adjusting screw rod to separate it from the carrying tray, and it can be used. This can avoid protecting the electronic scale body when placing the refrigerant tank, thereby improving its service life.

[0017] 2. The utility model is provided with a threaded sleeve, an adjusting threaded rod and a support block. By holding the support block, the adjusting threaded rod can be driven to move inside the threaded sleeve so that it can be probed into different positions. By observing the bulb level in the hidden groove, the balance degree of the electronic scale body can be observed, thereby maintaining the balance of the electronic scale body and ensuring that the sensor inside the electronic scale body is evenly stressed, thereby making the measured refrigerant weight more accurate.

[0018] The specific implementation of the present invention will be described in further detail below with reference to the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] Both sides of the electronic scale body 1 are fixedly connected with force plates 6, one side of the two force plates 6 is threadedly engaged with an adjustment screw 7, the adjacent sides of the two adjustment screws 7 are rotatably engaged with a supporting plate 8, the adjacent sides of the two supporting plates 8 are abutted against the supporting disc 2, a display controller 9 is provided on one side of the electronic scale body 1, and a horizontal component 10 is provided on the upper side of the electronic scale body 1.

[0030] See also Figure 1 The horizontal component 10 includes a hidden groove 101 opened on the upper side of the electronic scale body 1 and a bulb level 102 fixedly connected to the inner wall of the hidden groove 101. When the electronic scale body 1 is placed, the flatness of the electronic scale body 1 can be observed through the bulb level 102 in the hidden groove 101 to improve the flatness.

[0031] See also Figure 1 A buffer pad 11 is fixedly connected to the upper side of the carrying plate 2, and an anti-slip strip 12 is provided on the upper side of the buffer pad 11. When the medium can is placed, the contact between the medium can and the buffer pad 11 can reduce its instantaneous impact force. The anti-slip strip 12 can improve the anti-slip effect of the placed medium can.

[0032] See also Figure 2 The outer sides of the multiple support blocks 5 are fixedly connected with force pads 13, and the outer sides of the multiple force pads 13 are provided with protective grooves 14. When the position of the support block 5 needs to be adjusted, the support block 5 can be rotated and adjusted by holding the force pad 13. The protective grooves 14 can increase the friction between the force pad 13 and the palm when holding the hand.

[0033] See also Figure 3 A guide opening 15 is provided on the opposite side of the two force-bearing plates 6, and a guide rod 16 is fixedly connected to the opposite side of the two supporting plates 8. The two guide rods 16 cooperate with the two guide openings 15. When the supporting plate 8 moves, it is guided inside the guide opening 15 by the guide rod 16, thereby improving the stability of the movement of the supporting plate 8.

[0034] See also Figure 1A carrying shell 17 is fixedly connected to one side of the electronic scale body 1, and the carrying shell 17 cooperates with the display controller 9. When not in use, the display controller 9 can be inserted into the carrying shell 17 for storage. When needed, it can be taken out of the carrying shell 17 and controlled by controlling the display controller 9. The separation between the display controller 9 and the electronic scale body 1 can reduce the impact on the electronic scale body 1 during operation.

[0035] Please refer to the figure. The adjacent sides of the two supporting plates 8 are set to be inclined. The adjacent sides of the two supporting plates 8 are fixedly connected with soft pads 18. When the supporting plates 8 are tightened, they will gradually contact and squeeze the supporting disc 2. The soft pads 18 can be interposed in between to reduce the degree of damage to the supporting disc 2.

[0036] The working principle of the air conditioner refrigerant charging metering tool of the embodiment of the present application is as follows: when in use, the corresponding support block 5 can be rotated to drive the adjustment threaded rod 4 to move inside the threaded sleeve 3, so that the support block 5 can be protruded to different positions. By observing the bulb level 102 in the hidden groove 101, the balance degree of the electronic scale body 1 can be observed, so that the electronic scale body 1 can be kept balanced, and the sensor inside the electronic scale body 1 can be ensured to be evenly stressed, thereby making the measured refrigerant weight more accurate;

[0037] By adjusting the screw rod 7 to rotate on the force plate 6, the supporting plate 8 is pushed to support both sides of the supporting disc 2. When the refrigerant tank is placed on the upper side of the supporting disc 2, the supporting plate 8 supports the supporting disc 2, so that the pressure during placement is offset by the supporting plate 8 and will not be transmitted to the inside of the electronic scale body 1 through the supporting disc 2. After the placement is stable, the supporting plate 8 is moved by rotating the adjusting screw rod 7 to separate it from the supporting disc 2, and it can be used. This can avoid protecting the electronic scale body 1 when placing the refrigerant tank and improve its service life.
