[0024] The present invention is further described in detail below in conjunction with the embodiments.
[0025] The specific embodiment of the vibration detector with adjustable detection head length provided by the utility model is as follows:
[0026] See also Figure 1-5 The vibration detector with adjustable detection head length includes a detector body 1; a display screen and operation buttons are provided on the front side of the detector body 1, and a single-chip microcomputer and a vibration detection circuit are built in. The vibration detection of the vibration detector is an existing technology, so it will not be repeated in this embodiment.
[0027] A vertical slide groove 2 is provided at the rear of one side of the detector body 1, and a slide seat 3 sliding along the slide groove 2 is provided in the slide groove 2. The slide seat 3 is a shell structure sliding on the inner side of the slide groove 2, and the lower side of the slide seat 3 has an opening.
[0028] The upper side of the slide 3 is connected with a cylinder 4, and the interior of the cylinder 4 is connected with the interior of the slide 3; the upper end of the detector body 1 is provided with a through hole corresponding to the slide 2 for the cylinder 4 to pass through. The end of the cylinder 4 away from the slide 3 is installed with a detection head 5 for detecting vibration, and the detection head 5 is connected with a transmission line 6. The transmission line 6 adopts an elastic spiral signal cable. When the detection head 5 moves, the transmission line 6 can be regularly extended and retracted to avoid tangled lines; the transmission line 6 passes through the cylinder 4 and the slide 3, and the other end enters the interior of the detector body 1 from the end of the slide 2, and is connected to the single-chip microcomputer through the vibration detection circuit. During detection, the detection head 5 contacts the device under test, detects the vibration of the device under test and transmits it to the single-chip microcomputer for processing, and then displays the vibration data through the display.
[0029] In this embodiment, the total length of the slide 3, the cylinder 4 and the detection head 5 is no greater than the length of the slide slot 2; when the detector is stored, the detection head 5 can be prevented from extending out of the detector body 1, thereby protecting the detection head 5 and preventing damage to the detection head 5.
[0030] Steps 7 are symmetrically provided on both sides of the inner side of the groove 2, and the inner side surfaces of the steps 7 are provided with teeth 8 evenly distributed along the extension direction of the groove 2. A push handle 9 is slidably connected to the outer side of the slide seat 3, and the sliding direction of the push handle 9 is perpendicular to the extension direction of the groove 2. Two T-shaped guide columns 11 are connected to the inner side of the push handle 9, and the guide columns 11 pass through the outer side wall of the slide seat 3 and are slidably connected to the slide seat 3.
[0031] Two elastic members are provided between the push handle 9 and the slide seat 3. Limiting posts 10 cooperating with the teeth 8 are provided on both sides of the push handle 9. The elastic members keep the push handle 9 away from the slide seat 3 and make the limiting posts 10 cooperating with the teeth 8. In this embodiment, the elastic member is a coil spring 12, and the two elastic members are respectively sleeved on the outside of the two guide posts 11.
[0032] By pressing the push handle 9 inward, the limit column 10 can be separated from the tooth 8, and then the push handle 9 can be moved along the direction of the slide groove 2, and the push handle 9 drives the slide seat 3 and the cylinder body 4 to move along the slide groove 2, thereby adjusting the extension length of the detection head 5; loosening the push handle 9, the elastic member moves the push handle 9 outward, the limit column 10 cooperates with the tooth 8, and the push handle 9, the slide seat 3, the cylinder body 4 and the detection head 5 are positioned. When the detection head 5 is extended for a long time, it can easily contact the recesses and gaps of the equipment and perform vibration detection.
[0033] In order to facilitate pushing the push handle 9, anti-slip grooves are provided on the outer side of the push handle 9; the side of the push handle 9 facing the slide seat 3 is flat, and the thickness of the push handle 9 gradually decreases from the middle to the two ends, so that the outer side of the push handle 9 has two symmetrical inclined surfaces, both of which have anti-slip grooves, making the bidirectional pushing of the push handle 9 easier.
[0034] Finally, it should be noted that the above is only a preferred embodiment of the utility model and is not intended to limit the utility model.
