[0018] In order to make the technical means, creative features, achieving purposes and functions of the utility model easy to understand, the utility model will be further described below in conjunction with specific embodiments.
[0019] Such as Figures 1-4As shown in the figure, a new type of enclosed lead screw module includes a housing 1, a lead screw mechanism 3 is arranged inside the housing 1, a side cover 2 is arranged at the right end of the housing 1, and an adjusting mechanism 4 is arranged at the front of the housing 1; In summary, when the lead screw mechanism 3 drives the light shielding plate 404 to move to the middle of the photoelectric switch 403, the photoelectric switch 403 will send an electrical signal to an external terminal, and the external terminal will control the motor to reverse, so that the moving block 303 drives the connecting block 304 to move in the reverse direction, and thus by controlling the position of the adjusting component 402 in the chute 401, the stroke of the moving block 303 can be controlled, which is convenient for use.
[0020] The adjusting mechanism 4 includes a sliding groove 401, two adjusting components 402, a photoelectric switch 403 and a light-shielding plate 404. The sliding groove 401 is opened in the middle of the front side of the housing 1. The rear sides of the two adjusting components 402 are installed inside the sliding groove 401. The lower part of the photoelectric switch 403 is installed on the upper front side of the adjusting component 402. The rear side of the light-shielding plate 404 is installed on the front part of the lead screw mechanism 3. When the lead screw mechanism 3 drives the light-shielding plate 404 to move to the middle of the photoelectric switch 403, the photoelectric switch 403 will send an electrical signal to an external terminal, and the external terminal will control the motor to rotate in the reverse direction, so that the moving block 303 drives the connecting block 304 to move in the reverse direction. Thus, by controlling the position of the adjusting component 402 in the sliding groove 401, the stroke of the moving block 303 can be controlled, which is convenient for use. A scale 405 is arranged in the middle and lower part of the front side of the housing 1. Through the scale 405, the positions of the two adjusting components 402 can be conveniently adjusted quickly. The lead screw mechanism 3 includes a coupling 301, a lead screw 302, a lead screw 302, a moving block 303 and two connecting blocks 304. The opposite sides of the connecting blocks 304 are fixedly connected to the front and rear sides of the moving block 303. The outer circumference of the moving block 303 is slidably connected inside the housing 1. The middle part of the moving block 303 is threadedly connected to the outer circumference of the lead screw 302. One end of the lead screw 302 is installed at the output end of the motor through the coupling 301. By driving the motor to rotate forward and backward, the lead screw 302 rotates forward and backward. Since the moving block 303 is restricted from rotating, the moving block 303 drives the connecting blocks 304 to move left and right. The adjusting component 402 includes a slider 4021, two threaded rods 4022, two mounting holes 4023, a mounting plate 4024, two spring washers 4025 and four nuts 4026. The rear part of the slider 4021 is slidably connected inside the sliding groove 401. The rear ends of the threaded rods 4022 are fixedly connected to the left and right sides of the front part of the slider 4021. The mounting holes 4023 are opened on the left and right sides of the rear part of the mounting plate 4024. The threaded rods 4022 pass through the mounting holes 4023 and spring washers 4025 and two nuts 4026 are arranged on the front side of the front part of the threaded rods 4022. The spring washers 4025 and nuts 4026 are arranged on the front side of the rear part of the mounting plate 4024. A fixing bolt 4027 is threadedly connected to the upper left corner of the front part of the slider 4021. A rubber pad is installed at one end of the fixing bolt 4027 close to the housing 1. By means of the rubber pad, the friction between the fixing bolt 4027 and the housing 1 is increased, so that the mounting plate 4024 can be stably fixed in the middle of the sliding groove 401. Spring rods 5 are installed on the left inner wall of the housing 1 and the left part of the side cover 2. The moving block 303 is buffered by the spring rods 5 to prevent collision.
[0021] Working principle:
[0022] When the lead screw mechanism 3 drives the light shielding plate 404 to move to the middle of the photoelectric switch 403, the photoelectric switch 403 will send an electrical signal to an external terminal, and the external terminal will control the motor to rotate in the reverse direction, so that the moving block 303 drives the connecting block 304 to move in the reverse direction. Thus, by controlling the position of the adjusting component 402 in the sliding groove 401, the stroke of the moving block 303 can be controlled, which is convenient for use.
