Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to an automobile overhauling device, and more particular to a tester which is used for overhauling the engine, the radiator, and the tubes therebetween. 
     2. Description of the Prior Art 
     Conventional engine  101 , as shown in  FIG. 6 , is connected to grille  102  by tubes  103  directly. The tubes  103  are usually made by metal, and the engine and the grille are metal, too. After a long period of using, the tubes would probably rust, or even break. Thus, engine, grille, and the tubes checking and testing should be included in automobile overhauling procedure. 
     Conventional radiator grille tester, as shown in TW utility model TWM354734, is provided for connecting an engine to a radiator. Water of the engine and the radiator can flow into the tester. Servicemen can observe the water with the tester via a window of the tester. Further, the tester can detect temperature of the water. Thus, servicemen can judge whether the engine and the radiator is malfunctioned with the tester. 
     However, the tester mentioned above still has several disadvantages in practical using. When servicemen observe color of the water, the top viewing window is too small to observe the water clearly. Further, servicemen can hardly judge whether water is flowing or not. Therefore, obstruction of the tube, the radiator, or the engine can hardly be detected. 
     The present invention is, therefore, arisen to obviate or at least mitigate the above mentioned disadvantages. 
     SUMMARY OF THE INVENTION 
     The main object of the present invention is to provide another tester which is provided for observing status of the engine, the radiator, and the tubes easily and clearly. 
     To achieve the above and other objects, a radiator grille tester of the present invention is used for connecting an engine to a radiator. The radiator grille tester includes a main body. 
     The main body has a water channel. The main body has two adapters, a transparent tube, and a detector. The adapters are located at two ends of the channel respectively. The channel is defined in the transparent tube and the detector. One of the adapters is adapted for the engine to connect thereto. The other one of the adapters is adapted for the radiator to connect thereto, so that water is able to flow from the engine to the channel via one of the adapters, flow passing through the transparent tube and the detector, and flow from the channel to the radiator via the other one of the adapters. 
     Further, the detector has at least one sensor. The sensor is adapted for showing one of temperature of the water and inner pressure of the channel. 
     The present invention will become more obvious from the following description when taken in connection with the accompanying drawings, which show, for purpose of illustrations only, the preferred embodiment(s) in accordance with the present invention.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     Please refer to  FIG. 1  to  FIG. 3  for a preferred embodiment of the present invention. The radiator grille tester of the present embodiment is used for connecting an engine  1  to a grille  2  by tubes  11 ,  12 . The radiator  2  may have a heat dispenser  22 . Thus, water in the engine  1  can flow into the radiator  2  via the radiator grille tester. The radiator grille tester includes a main body. 
     The main body includes two adapters  3 ,  4 , a transparent tube  5 , and a detector  6 . Preferably, a quick release joint  7  is also included. 
     The transparent tube  5  connects one adapter  3  to the detector  6 . The quick release joint  7  connects the other one adapter  4  to the detector  6 . The main body has a channel. More particularly, the channel extends from the adapter  3  to the other adapter  4 , passing through the transparent tube  5 , the detector  6 , and the quick release joint  7 . The adapters  3 ,  4  are located at two ends of the channel. The transparent tube  5  may be made by plastic of the similar material, so that the transparent tube  5  is capable of being bent. Further, user can observe the water in the channel with the transparent tube  5 . 
     The adapters  3 ,  4  are connected to the engine  1  and the grille  2  by the tubes  11 ,  12  respectively. More particularly, one adapter  3  is provided for the engine  1  to connect thereto. The other adapter  4  is provided for the radiator  2  to connect thereto. Thus, water is able to flow from the engine  1  to the channel via one adapter  3 , flowing passing through the transparent tube  5  and the detector  6 , and flow from the channel to the radiator  2  via the other adapter  4 . Since the transparent tube  5  is contained in the main body, water flow in the channel would show up in the transparent tube  5 . Thus, user can check the water flow easily. Preferably, each of the adapters  3 ,  4  has a detachable connection tube  31 ,  41 . User can exchange the connection tubes  31 ,  41  with a larger one  32 , as shown in  FIG. 2A , or a smaller one. 
     The quick release joint  7  connects the detector  6  to the adapter  4 . In other possible embodiments of the present invention, the quick release joint may be disposed between the detector  6  and the transparent tube  5  or between the transparent tube  5  and the adapter  3 . The quick release joint  7  is provided for being decomposed selectively, so that the main body is partitioned into an engine portion, which is connected to the engine, and a radiator portion, which is connected to the radiator. Simultaneously, the channel is partitioned into a sub-channel of the engine and a sub-channel of the radiator portion. 
     The detector  6  includes a base portion  61 , a head portion  62 , and two sensors  63 ,  64 . The detector  6  can further include a compression head  65  and another quick release joint  66 . The base portion  61  has a hole  611  and an opening  612 . The opening  612  communicates laterally with the hole  611 . Laterally communication means that axis of the opening  312  is not parallel to axis of the hole  611 . In the present embodiment, the hole  611  extends horizontally, and the opening  612  extends vertically. The head portion  62  is formed with a chamber  621  therein and several connection apertures  622  communicating with the chamber  621  respectively. More particularly, there are three connection apertures  622  in the present embodiment, as shown in  FIG. 2  and  FIG. 3 . Each of the connection apertures  622  communicates with the chamber  621 . The connection apertures  622  are threaded. The head portion  62  may further have a transparent window  623 . Thus, user can observe into the chamber  621  via the transparent window  623 . One sensor  63  is a temperature sensor so as to sense and display the temperature of the chamber  621 . The other sensor  64  is a pressure sensor so as to sense and display the pressure of the chamber  621 . It is noted that water in the chamber would flow into the chamber  621  via the opening  612  and the hole  611 , so that temperature and pressure of the chamber  621  would almost equal to temperature and pressure of the water in the channel. For describing purpose, it is considered that temperature and pressure of the chamber is namely temperature and pressure of the water in the channel. The sensors  63 ,  64  are disposed on the head portion  62  and are located in the connection apertures  622  respectively. Temperature and pressure detection of the sensors  63 ,  64  can be progressed toward the chamber  621  via the connection apertures  622 . Thus, temperature and pressure of the chamber or the channel can be displayed or shown up. 
     In the preferred embodiment of the present invention, one sensor  63  may has a lighting device, such as LED. The sensor  63  can project light into the chamber  621 . As such, user can also observe the water in the chamber  621  via the transparent window  623 . The compression head  65  is disposed on the head portion  62 , and is located at one of the connection apertures  622 . User can inject fluid with a compressor into the chamber  621  via the compression head  65  so as to raise pressure of the chamber  621 . The quick release joint  66  connects the head portion  62  to the base portion  61 , so that the opening is connected to the chamber. The quick release joint  66  is used for decomposing, so that the head portion  62  can be detached from the base portion  61 . 
     Accordingly, the radiator grille tester can be assembled between the engine  1  and the radiator  2 , connecting the engine  1  to the radiator  2 , as shown in  FIG. 1 . User can overhaul the engine, the radiator, and the tubes by using the radiator grille tester. Firstly, user can check flow and color of the water to know whether the tubes are ruptured, obstructed, or rusted. 
     Secondly, user can connect the compression head  65  to a compressor, such as a cylinder  8  shown in  FIG. 4 . Air or water is injected into the chamber so as to raise pressure of the chamber. User can read the pressure on the sensor  64  then. If value of the pressure can be maintained, tubes, engine, and the radiator may be kept well without rupture. Otherwise, if value of the pressure decreases rapidly, tubes, engine, and the radiator would probably ruptured. 
     Tube rupture would follow with engine oil leakage. Water in engine would be contaminated by the engine oil. Thus, water in the engine and the radiator should be exchanged. Please refer to  FIG. 5 . User can decompose the quick release joint  7 , connect the adapter  4  to a water pump  9 , and connect the quick release joint  7  to a tube  91 . The water pump  9  is then started. Contaminated water would be expelled out from the radiator  2  and the engine  1 , and the water in engine is then refreshed. 
     To conclude, the radiator grille tester of the present invention can be used in automobile overhauling, making overhauling easier and quicker.
