[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model.
[0027] Please refer to Figures 1-7 , the present utility model provides a telescopic height jig, including a sliding rod 3 and a main rod 6 that slidably sleeved on the sliding rod 3. Both the main rod 6 and the sliding rod 3 are made of aluminum alloy. Through the sliding rod 3 and the main rod 6, not only can the length be changed by sliding, but also relative rotation can occur. A guiding and limiting groove 9 is circumferentially provided on the main rod 6, and a through hole 11 is provided on the outer side of the sliding rod 3. A limiting rod 4 is passed through the guiding and limiting groove 9 and the through hole 11 between the main rod 6 and the sliding rod 3. The movement of the limiting rod 4 inside the guiding and limiting groove 9 causes the main rod 6 and the sliding rod 3 to slide integrally, thereby changing their overall length. When the device is in use, by moving the limiting rod 4 in the guiding and limiting groove 9, the sliding rod 3 follows the movement of the limiting rod 4, so that the overall length of the slidably sleeved sliding rod 3 and main rod 6 changes, thus completing the height telescopic change process.
[0028] Please refer to Figures 1-7 , the guiding and limiting groove 9 is provided with a turning portion 10. When the limiting rod 4 is located at the turning portion 10, the main rod 6 and the sliding rod 3 are limited and fixed. The setting of the turning portion 10 enables the limiting rod 4 to be clamped by the turning portion 10 when the sliding rod 3 is located at the turning portion 10, thereby fixing the overall length of the sliding rod 3 and the main rod 6. This process only requires the sliding rod 3 to rotate to drive the limiting rod 4.
[0029] Please refer to Figures 1-7 , multiple different turning portions 10 can be provided on the guiding and limiting groove 9. Through different turning portions 10, different lengths of the main rod 6 and the sliding rod 3 can be limited and fixed. By providing different turning portions 10 on the guiding and limiting groove 9, the limiting rod 4 can be clamped on different turning portions 10, thereby realizing the limiting and fixing of different lengths of the main rod 6 and the sliding rod 3, improving the applicable range of the device, and further improving the practicality of the device.
[0030] Please refer to Figures 1-5, the guide and slide limiting groove 9 can be an inverted L shape, and one end of the inverted L shape serves as the turning part 10 to realize the limiting and fixing of the main rod 6 and the sliding rod 3.
[0031] Please refer to Figures 1-5 , a buffer member 5 for buffering when the sliding rod 3 moves is provided at the bottom end of the sliding rod 3. The buffer member 5 is made of silica gel material. Through the buffer member 5, the impact force caused by the sliding rod 3 falling on the bottom can be reduced.
[0032] Please refer to Figures 1-5 , a top connecting member 2 is threadedly installed at one end of the sliding rod 3 away from the main rod 6. A top contact member 1 is fixed to the top of the top connecting member 2. The top contact member 1 is used to contact the element touched at the top. The top contact member 1 is made of PEEK material, and the top contact member 1 is fixedly connected to the top connecting member 2 through a fastener. PEEK is polyether ether ketone, which is a special engineering plastic with excellent properties such as high temperature resistance, self-lubrication, easy processing, and high mechanical strength. Through the top contact member 1 made of PEEK material, the impact force when the top of this device contacts and collides with the outside can be reduced, and the service life of this device can be extended.
[0033] Please refer to Figures 1-7 , a bottom connecting member 7 is threadedly installed at one end of the main rod 6 away from the sliding rod 3. A bottom contact member 8 is fixed to the bottom of the bottom connecting member 7. The bottom contact member 8 is used to contact the element touched at the bottom. The bottom contact member 8 is made of PEEK material, and the bottom contact member 8 is fixedly connected to the bottom connecting member 7 through a fastener. Through the bottom contact member 8 made of PEEK material, the impact force when the bottom of this device contacts and collides with the outside can be reduced, and the service life of this device can be extended.
[0034] Working principle: When this device is in use, first place the bottom contact member 8 on the bottom plane of the space to be tested. At this time, the whole device is in a contracted state, that is, the sliding rod 3 and the main rod 6 are in a contracted state as a whole. Then adjust the sliding rod 3 and the main rod 6 to an extended state, and then fix the overall length of this device through the cooperation of the limiting rod 4 and the turning part 10. Then move the device as a whole and slowly raise the bottom until the top contact member 1 is about to contact the top contact surface of the space to be tested. At this time, since the bottom connecting member 7 is threadedly installed on the sliding rod 3, the device can be finely adjusted by rotating the bottom connecting member 7, which further improves the accuracy of this device. At this time, the distance between the top contact surface of the space to be tested and the bottom contact member 8 of this device can be obtained, and then the device can be taken out as a whole to obtain the measurement result, thus completing the working process of this device;
[0035] In addition, through the multiple different turning parts 10 provided in this device, it can measure multiple heights to be measured, improving the adaptable height measurement range of this device.
[0036] Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
