Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, and in particular to a nut cap tightening device. Background Technology

[0002] An air conditioner evaporator is made by passing a set of U-shaped tubes through fins, expanding the tubes, and welding them together. During its production process, the nuts and caps need to be tightened to check the sealing of the pipes and to fill them with protective gas to protect the evaporator. Air conditioner manufacturers generally use assembly line operations for sealing tests. The products to be inspected on the line move with the rhythm of the assembly line, and the operators repeatedly take the nuts and caps from the storage location and install them on the pipes one by one.

[0003] Chinese Patent Publication No.: CN 217317799 U, Publication Date: August 30, 2022. This utility model relates to a toggle switch nut tightening device, characterized in that: a hexagonal head is fixedly connected to the upper part of the wrench seat, and an integrated reinforcing ring is provided below it; an integrated wrench locking slot is provided below the reinforcing ring. The drawback of this technical solution is that it is difficult to perform efficient continuous batch tightening operations for operations requiring continuous nut tightening, thus reducing tightening efficiency.

[0004] In summary, the tightening device has the disadvantages of making it difficult to perform continuous batch tightening operations and reducing tightening efficiency when tightening nuts. Utility Model Content

[0005] The present invention aims to overcome the shortcomings of existing tightening devices in tightening nuts, such as difficulty in continuous batch tightening operations and reduced tightening efficiency, and provides a nut cap tightening device that facilitates continuous batch tightening operations and improves tightening efficiency.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A nut cap tightening device includes a rotating seat with a storage cavity. One end of the storage cavity is a discharge port, and the other end is a feed port. A plurality of nut cap bodies are slidably connected inside the storage cavity. The rotating seat is provided with an anti-slip push rod, a limiting rod, and a fixing rod. The anti-slip push rod is movably connected to the rotating seat. The limiting rod and the fixing rod are both movably connected to the rotating seat through the anti-slip push rod. The limiting rod is placed at the feed port, and one end of the fixing rod is pressed against the nut cap body closest to the feed port.

[0008] The interior of the screw-in seat is a storage cavity for stacking multiple nut caps, enabling batch tightening without the need for separate handling, thus improving tightening efficiency. The storage cavity is a central cavity open at both ends. One end has an inlet for replenishing nuts caps to be tightened, and the other end has an outlet for nuts caps to contact the pipe before tightening and for unloading nuts caps after tightening, further improving operational efficiency. The outer surface of the screw-in seat has an anti-slip push rod to make the surface of the screw-in seat protrude, preventing slippage during tightening and enhancing the tightening tightness with the pipe. A limiting rod is movably connected to the inlet of the screw-in seat to open and close the inlet and position the nut caps. A fixing rod moves to fix and press the nut caps, ensuring that the nut caps rotate with the anti-slip push rod and the screw-in seat, further improving stability and tightening tightness. Both the limiting rod and the fixing rod are moved by the anti-slip push rod, making operation convenient and the structure compact. The device achieves the effects of increasing the turning efficiency and tightness of nuts and caps through tightening, enabling batch tightening operations, and featuring a compact structure and convenient operation.

[0009] Preferably, the end face of the rotating seat is provided with a first sliding groove, and an elastic mechanism is provided within the first sliding groove. One end of the elastic mechanism is connected to the first sliding groove, and the other end of the elastic mechanism is connected to a first slider. A limiting rod is connected to the first slider. The end face of the rotating seat near the feed inlet is provided with the first sliding groove. The elastic mechanism is connected within the first sliding groove and drives the first slider, so that the limiting rod connected to the first slider can automatically reset and open the feed inlet after the anti-slip push rod loses its force, allowing the tightened nut cap to be quickly removed. This further improves the ease of use of the device and the efficiency of the tightening operation.

[0010] Preferably, the rotating base has a second sliding groove on its side, within which is a second elastic mechanism. One end of the second elastic mechanism is connected to the first sliding groove, and the other end is connected to a second slider. A fixed rod is connected to the second slider. The second sliding groove on the side of the rotating base, with the elastic mechanism connected within it and driving the second slider, allows the fixed rod connected to the second slider to automatically reset and loosen the nut cap after the anti-slip push rod is released, enabling the tightened nut cap to be smoothly removed. This further improves the ease of use of the device and the efficiency of tightening operations.

[0011] Preferably, the end face of the limiting rod is provided with a sliding ramp, and one end of the anti-slip push rod is slidably connected to the sliding ramp. The limiting rod, via the sliding ramp, allows the anti-slip push rod to move to the other side as it moves on the rotating seat, simplifying operation and limiting the feed inlet. This achieves the effect of simplifying the device structure and improving operational efficiency.

[0012] Preferably, the anti-slip push rod is connected to a top block, and the side of the rotating seat has a third sliding groove that communicates with the second sliding groove. The top block is slidably connected to the third sliding groove, and the top block is pressed against the other end of the fixing rod. The inner wall of the anti-slip push rod is connected to the top block, and the top block slides along the third sliding groove and finally pushes the fixing rod on the second sliding groove to lock the nut cap. This improves the stability of the nut cap locking operation.

[0013] Preferably, the rotating base is provided with a limiting slide groove, into which a slide rod is inserted. The other end of the anti-slip push rod is connected to a connecting rod, which is connected to the slide rod. The slide rod has a limiting groove, and the rotating base is connected to a third slider, which slidably connects to the limiting groove. The rotating base is connected to the slide rod via the limiting slide groove, allowing the slide rod to reciprocate within the groove via the anti-slip push rod on the connecting rod. The third slider, through the limiting groove, limits the movement path, thereby limiting the pushing path of the anti-slip push rod and preventing excessive pushing, thus improving operational efficiency. This achieves the effect of improving the operational stability and efficiency of the device.

[0014] The beneficial effects of this utility model are: improving the turning efficiency and tightness of the nut cap through the tightening device; realizing batch tightening operations; the device has a compact structure and is easy to operate; improving the ease of use of the device; improving the stability of the nut cap locking operation; and improving the operational stability and efficiency of the device.

[0024] Example 1:

[0025] like Figure 1 , 2 As shown, a nut cap tightening device includes a rotating base 1, a storage cavity 2, one end of the storage cavity 2 is a discharge port, and the other end of the storage cavity 2 is a feed port. A plurality of nut cap bodies 3 are slidably connected in the storage cavity 2. The rotating base 1 is provided with an anti-slip push rod 4, a limiting rod 5 and a fixing rod 6. The anti-slip push rod 4 is movably connected to the rotating base 1. The limiting rod 5 and the fixing rod 6 are both movably connected to the rotating base 1 through the anti-slip push rod 4. The limiting rod 5 is placed at the feed port, and one end of the fixing rod 6 is pressed against the nut cap body 3 closest to the feed port.

[0026] like Figure 2 , 3 As shown, the end face of the rotating seat 1 is provided with a first sliding groove 7, and an elastic mechanism 8 is provided in the first sliding groove 7. One end of the elastic mechanism 8 is connected to the first sliding groove 7, and the other end of the elastic mechanism 8 is connected to a first slider 9. The limiting rod 5 is connected to the first slider 9.

[0027] like Figure 3 As shown, the side of the rotating seat 1 is provided with a second sliding groove 10, and an elastic mechanism 2 11 is provided in the second sliding groove 10. One end of the elastic mechanism 2 11 is connected to the first sliding groove 7, and the other end of the elastic mechanism 2 11 is connected to a second slider 12. The fixing rod 6 is connected to the second slider 12. The end face of the limiting rod 5 is provided with a sliding inclined surface 13, and one end of the anti-slip push rod 4 is slidably connected to the sliding inclined surface 13.

[0028] like Figure 2 , 4 As shown, the anti-slip push rod 4 is connected to the top block 14, and the side of the rotating seat 1 is provided with a third slide groove 15. The third slide groove 15 is connected to the second slide groove 10. The top block 14 is slidably connected to the third slide groove 15, and the top block 14 is pressed against the other end of the fixing rod 6.

[0029] like Figure 4 As shown, the rotating base 1 is provided with a limiting slide groove 16, and a slide rod 17 is inserted into the limiting slide groove 16. The other end of the anti-slip push rod 4 is connected to a connecting rod 18, which is connected to the slide rod 17. The slide rod 17 is provided with a limiting groove 19. The rotating base 1 is connected to a third slider 20, which is slidably connected to the limiting groove 19.

[0030] like Figure 1-4As shown: There are at least two limiting rods 5 and fixing rods 6. In this embodiment, two objects are arranged as an example to make the nut cap body 3 subject to uniform and stable force application.

[0031] Both the first elastic mechanism 8 and the second elastic mechanism 11 are spring structures, so that the limiting rod 5 and the fixing rod 6 can be automatically reset.

[0032] The inlet of storage chamber 2 is fitted with a rear cover to prevent the nut cap 3 from falling out from the rear during installation.

[0033] In use: Connect the nut cap 3 at the outlet end of the rotating seat 1 to the pipe port and rotate it to make the pipe and nut cap 3 threadedly connected.
