Technical Field
[0003] The present disclosure relates to the technical field of detections of inflatable products, and in particular to a test cover replacement structure for an air leakage detection device of inflatable products.
Background
[0004] Common inflatable products, such as inflatable beds, inflatable tables, inflatable ships and inflatable toys, on the market are very popular with consumers because they are light, foldable, easy to carry and comfortable. They are widely applied and are necessary products at home and for travel. They have a broad market prospect. The airtightness of inflatable products is a key index deciding the quality of inflatable products and the airtightness directly influences consumers' experience in the use of inflatable products. For this reason, an airtightness detection, namely, air leakage detection will be performed for most inflatable products before they are launched on the market.
[0005] Currently, a special detection device is usually used to perform an air leakage detection and a sealed test cover is provided for the detection device. An inflatable product is put into the test cover and the air pressure or air in the test cover is detected to determine whether the inflatable product leaks or not. In reality, a manufacturer will usually produce various inflatable products, such as inflatable beds, inflatable ships and inflatable toys. Since
each type of inflatable product has a different structure, the test cover cooperating with each type of inflatable product will also be different. If the test cover used does not match an inflatable product during an air leakage detection of the inflatable product, the efficiency of the air leakage detection will be influenced or the air leakage detection will even fail. Thus, manufacturers currently provide at least an air leakage detection device for each type of inflatable product to guarantee that an air leakage detection can be performed successfully for each type of inflatable product.
[0006] However, a problem is also brought about the utilization of a special air leakage detection device specially purchased or produced for inflatable products with a small output, which will undoubtedly increase manufacturing costs and bring about a certain amount of waste.

The second fixing piece is disposed in the test frame and is connected with the lifting device. When the test cover is located in the test frame the first fixing piece is connected with the second fixing piece.
[0009] In an example thereof, the distance between the lower end face of the plurality of rollers and the lower end face of the test cover is d and a height of the guide rail is greater than d.
[0010] In another example thereof, the guide rail comprises a first section and a second section, the first section is detachably connected with the conveyor line, and the second section extends into the test frame.

[0028] Referring to Figs. 1-3, a test cover replacement structure for an air leakage detection device of inflatable products is shown. As shown in Fig. 1, the air leakage detection device may comprise a conveyor line 40 for conveying inflatable products and a test frame 50. A test cover 60 is disposed in the test frame 50, and the test cover is connected with a lifting device 70 which drives the test cover 60 to move up or down.
[0029] The test cover replacement structure comprises rollers 10 disposed on the two sides of the test cover 60, a guide rail 20 detachably disposed on the conveyor line 40 and in the test frame 50, and a fixing assembly 30 which fixes a location the test cover 60. A lower end face of the rollers 10 is higher than a lower end face of the test cover 60. The fixing assembly may comprise a first fixing piece 31 and a second fixing piece 32. The first fixing piece 31 is disposed on a side of the test cover 60. The second fixing piece 32 is disposed in the test frame 50 and is connected with the lifting device 70. When the test cover 60 is located in the test frame 50, the first fixing piece is connected with the second fixing piece. In embodiments, the first fixing piece 31 is connected with the second fixing piece 32 with a locking piece 33.
[0030] The test cover 60 needs to cooperate with the plane below (a lower upward facing surface in the testing frame in FIG. 1) to form a sealed test cavity. The airtightness of the sealed test cavity may be influenced if the guide rail 20 is directly disposed in the test cover 60. Therefore, the guide rail 20 is detachably disposed on the conveyor line 40 and in the test frame 50 in embodiments in the present disclosure. When it is necessary to replace the test cover 60, the guide rail 20 is mounted for a test cover replacement. The guide rail 20 is removed from the conveyor line 40 and the test frame 50 during an air leakage detection in the test cover 60. In addition, the lower end face of the rollers 10 is configured to be higher than the lower end face of the test cover 60 in order to guarantee that the rollers 10 will not
influence the sealing effect of a sealed test cavity when the test cover 60 and the plane below form the sealed test cavity, thus guaranteeing normal air leakage detection operations.
[0031] In addition, when the test cover 60 is replaced, the rollers 10 on the test cover 60 are cooperatively located on the guide rail 20. If the lower end face of the test cover still contacts the plane below in this case, a larger friction force needs to be overcome and the replacement difficulty is increased. Furthermore, after friction occurs at the lower end face of the test cover, the sealing effect of the formed sealed test cavity may be influenced. In view of this, as shown in Fig. 4, the distance between the lower end face of the rollers and the lower end face of the test cover is d and the height of the guide rail is greater than d.
[0032] In embodiments, the guide rail 20 comprises a first section and a second section. The first section is detachably connected with the conveyor line 40. The second section extends into the test frame 50. A baseplate is provided in the test frame 50 and the baseplate is located below the test cover 60. When the first section of the guide rail 20 is connected with the conveyor line 40, the second section is placed on the baseplate. The detachable connection between the guide rail 20 and the conveyor line 40 can be realized in a locking or snap-in way or other suitable ways. In embodiments, a snap-in connection is realized between guide rail 20 and the conveyor line 40, a connecting seat 21 is connected with the first section of the guide rail 20, and a snap-in seat 22 cooperating with the connecting seat 21 is provided on the conveyor line 40 accordingly. When the guide rail is mounted, it is only necessary to keep the connecting seat 21 and the snap-in seat 22 in fit. [0033] The fixing assembly 30 further comprises a locking piece 33. The locking piece 33 joins the first fixing piece 31 and the second fixing piece 32 so as to lock the first fixing piece 31 and the second fixing piece 32. In the illustrated embodiment, the locking piece 33 is a pin, and a fixing hole for the pin to pass through is provided in both the first fixing piece 31 and the second fixing piece 32.
[0034] An exemplary operational principle of the replacement structure for replacing the test cover 60 is as follows:
[0035] First, raise the test cover 60 by using the lifting device 70 of the test cover and then mount the guide rail 20 on the conveyor line 40. The guide rail 20 will extend to the baseplate of the test frame 50. Next, lower the test cover 60 and keep the rollers 10 and the guide rail 20 in fit, then remove the pin 33 from the first fixing piece 31 and the second fixing piece 32. With pin 33 removed, pull out the test cover 60 to the conveyor line 40 and remove the test cover 60.
[0036] Next, place a new test cover 60 on the conveyor line 40. Keep the rollers 10 and the guide rail 20 in fit. Push the test cover 60 until the test cover 60 goes into the test frame 50 along the guide rail 20. After the test cover 60 goes into the test frame 50, connect the first fixing piece 31 and the second fixing piece 32, and then fix them by use of the pin 33 to complete the replacement of the test cover.
[0037] Finally, raise the new test cover 60 by using the lifting device 70 and remove the guide rail 20 from the conveyor line 40.
[0038] An advantage, among others, of the embodiments disclosed herein is that, with the aid of a seal cover replacement structure added to an air leakage detection device, the replacement of different types of test covers may be realized without influencing the air leakage detection performance of the seal cover 60. Thus, an air leakage detection device can perform an air leakage detection for different types of inflatable products and the utilization of the air leakage detection device is improved.
