Technical Field

[0001] The utility model relates to the technical field of curtain motor testing, in particular to a testing device for the winding function of a curtain motor. Background Art

[0002] An electric curtain is a way to control the curtain by driving with a motor. It can be divided into built-in type and external type in terms of installation. According to different operating mechanisms and decorative effects, electric curtains are divided into electric opening and closing curtain series, electric lifting curtain series, electric ceiling curtain (outdoor electric awning and indoor electric awning), electric sunshade board, electric sunshade awning and other series, specifically such as venetian blinds, roller blinds, roman blinds, soft yarn curtains, accordion curtains, honeycomb curtains, etc.

[0003] The motor structures adopted by existing curtain motors are relatively complex and have diverse functions. When factories produce, they need to test whether the curtain motor can work normally and its service life. Among them, the manual starting function of the curtain motor needs to be tested manually. Since the pulling forces of different people are different, it is easy to apply too much force when pulling the switch, resulting in damage. Therefore, repeated testing is required during the testing process, which has the disadvantages of complex testing and extended testing cycle. At the same time, when testing the curtain motor, it is necessary to install a curtain roll for testing the winding function. Since the curtain roll needs to be assembled and tested with the output shaft of the curtain motor, the operation process requires disassembling the machine cover of the curtain motor and then installing and connecting the output shaft of the curtain motor and the curtain roll through bolts. The installation process is cumbersome, thus reducing the testing efficiency.

[0004] Therefore, it is extremely urgent to design a testing device for the winding function of a curtain motor to solve the above defects, which is particularly important. Summary of the Utility Model

[0025] Embodiment:

[0026] Please refer to Figures 1 - 6 , the present utility model provides a technical solution:

[0027] A curtain motor winding function test device, including a support frame 1, a guide rail frame 2 is fixedly installed at the top of the front of the support frame 1, a tensile test switch 3 is fixedly installed at the left end of the guide rail frame 2, a machine cover 4 is fixedly installed at the right end of the guide rail frame 2, a curtain motor body 5 is fixedly installed at the right end of the top of the machine cover 4, a curtain seat 6 is fixedly installed at the bottom of the machine cover 4, a winding rotating shaft 7 is rotatably connected inside the curtain seat 6, a curtain roll 8 is fixedly connected to the outside of the winding rotating shaft 7, a connecting sleeve 9 is fixedly connected to the top of the winding rotating shaft 7, and the connecting sleeve 9 is fixedly connected to the output shaft of the curtain motor body 5 through a quick-release pin 10.

[0028] First, both the left and right ends of the back of the guide rail frame 2 are fixedly connected with mounting plates 201, and the two groups of mounting plates 201 are fixedly connected to the support frame 1 through mounting screws. A hanging wheel 202 is movably installed at the right end inside the guide rail frame 2, a connecting ear 203 is fixedly connected to the bottom end of the hanging wheel 202, and the connecting ear 203 is fixedly connected to the top end of the curtain roll 8 through a connecting pin 204. The guide rail frame 2 is installed at the top of the front of the support frame 1 through the mounting plates 201. When testing the winding function of the curtain motor, after installing and connecting the curtain roll 8 and the curtain motor body 5, the top end of the curtain roll 8 is installed and connected to the connecting ear 203 at the bottom end of the hanging wheel 202 through the connecting pin 204, so that when the curtain roll 8 is wound and unwound, the hanging wheel 202 assists in rolling inside the guide rail frame 2, enabling the curtain roll 8 to be smoothly unwound.

[0029] Furthermore, an S-shaped pressure sensor 301 is fixedly installed inside the tensile test switch 3, and a start switch 302 is fixedly installed inside the tensile test switch 3 and below the S-shaped pressure sensor 301. A pull rope 303 is fixedly connected to the bottom end of the S-shaped pressure sensor 301, and a pull ring 304 is fixedly connected to the bottom end of the pull rope 303. By pulling the pull rope 303 through the pull ring 304, when pulling the S-shaped pressure sensor 301 through the pull rope 303, the specific value of the test tensile force can be obtained. At the same time, when pulling the S-shaped pressure sensor 301, its bottom end will deform and touch the start switch 302. Through the S-shaped pressure sensor 301, both the specific tensile force value can be obtained and the start switch 302 can be prevented from being damaged due to excessive tensile force. The curtain motor body 5 is started through the start switch 302 to perform the winding and unwinding function test.

[0030] Then, an operation door 401 is rotatably connected to the outer side of the hood 4, and a door handle is fixedly connected to the outer side of the left end of the operation door 401. When installing and connecting the curtain roll 8 and the curtain motor body 5, the curtain base 6 is butted against the bottom of the hood 4, so that the output shaft of the curtain motor body 5 automatically inserts into the inner side of the connecting sleeve 9. Then, the operation door 401 is opened, and the quick-release pin 10 is used to quickly connect between the connecting sleeve 9 and the output shaft of the curtain motor body 5.

[0031] Furthermore, a plurality of positioning posts 601 are fixedly connected to the top end of the curtain base 6, and positioning jacks are provided at positions corresponding to the plurality of positioning posts 601 at the bottom of the hood 4. The winding rotating shaft 7 is rotatably connected to the curtain base 6 through a bearing 602. When docking the curtain base 6 and the hood 4, the positioning posts 601 are aligned with the positioning jacks at the bottom of the hood 4, so as to facilitate the quick installation and positioning of the curtain base 6. After connecting and fixing the connecting sleeve 9 and the output shaft of the curtain motor body 5, the curtain base 6 and the hood 4 are fixed, so that when the curtain motor body 5 is started, the connecting sleeve 9 is driven to rotate under the connection of the bearing 602, thereby driving the winding rotating shaft 7 to rotate, and then performing the function test of winding and unwinding the curtain roll 8.

[0032] Secondly, connection holes 1001 adapted to the quick-release pin 10 are provided inside the connecting sleeve 9 and the output shaft of the curtain motor body 5. A pin shaft 1002 is threadedly connected inside the quick-release pin 10. One end of the pin shaft 1002 located inside the quick-release pin 10 is fixedly connected to a spring 1003, and one end of the spring 1003 away from the pin shaft 1002 is fixedly connected to a movable block 1004. A plurality of ball studs 1005 are movably installed inside the quick-release pin 10 and outside the movable block 1004. A card slot 1006 adapted to the ball studs 1005 is provided inside the connecting sleeve 9. After the output shaft of the curtain motor body 5 is inserted into the inner side of the connecting sleeve 9, the quick-release pin 10 is inserted into the inner side of the connection hole 1001. Then, the pin shaft 1002 is rotated to push the movable block 1004, so that the ball studs 1005 are extruded from the inner side of the quick-release pin 10, and the ball studs 1005 are snapped into the card slot 1006, thereby quickly connecting and fixing between the output shaft of the curtain motor body 5 and the connecting sleeve 9, and further facilitating the quick test and improving the test efficiency.

[0033] Finally, a positioning head 1007 is fixedly connected to one end of the quick-release pin 10 located outside the connecting sleeve 9, and a turning handle 1008 is fixedly connected to one end of the pin shaft 1002 located outside the quick-release pin 10. After the quick-release pin 10 is inserted into the inner side of the connection hole 1001, it is positioned against the outer side of the connecting sleeve 9 under the action of the positioning head 1007. Then, the pin shaft 1002 is rotated through the turning handle 1008 to connect and fix between the output shaft of the curtain motor body 5 and the connecting sleeve 9.

[0034] In this embodiment, the implementation scenario is specifically as follows: When conducting the winding function test on the curtain motor body 5, first dock the curtain seat 6 with the machine cover 4 so that the output shaft of the curtain motor body 5 automatically inserts into the inner side of the connecting sleeve 9. Then, open the operation door 401 and insert the quick-release pin 10 into the inner side of the connecting hole 1001. Then, rotate the pin shaft 1002 to push the movable block 1004, thereby squeezing the ball 1005 out of the inner side of the quick-release pin 10, so that the ball 1005 is stuck into the card slot 1006, quickly connecting and fixing the output shaft of the curtain motor body 5 and the connecting sleeve 9. Install and connect the top end of the curtain roll 8 to the connecting ear 203 at the bottom end of the hanging wheel 202 through the connecting pin 204. Pull the pull rope 303 through the pull ring 304. When pulling the S-shaped pressure sensor 301 through the pull rope 303, the specific value of the test pulling force can be obtained. At the same time, when pulling the S-shaped pressure sensor 301, its bottom end will deform and touch the start switch 302. Through the S-shaped pressure sensor 301, both the specific pulling force value can be obtained and the start switch 302 can be prevented from being damaged due to excessive pulling force. Start the curtain motor body 5 through the start switch 302 to conduct the winding and unwinding function test. The curtain seat 6 is fixed to the machine cover 4, so that when the curtain motor body 5 starts, it drives the connecting sleeve 9 to rotate under the connection of the bearing 602, thereby driving the electric winding rotating shaft 7 to rotate, and then conducting the winding and unwinding function test on the curtain roll 8. The whole operation process is simple and convenient. Compared with the existing curtain motor winding function test method, the present utility model can both obtain the specific pulling force value and prevent damage caused by excessive pulling force through the design, and at the same time is convenient for quick assembly test, further improving the test efficiency.
