[0024] The technical solution of the present application is further described below in conjunction with specific embodiments, but the present application is not limited to these embodiments.
[0025] like Figure 1As shown, this embodiment provides a handlebar height detection device, the handlebar has a handle 11 and a riser 12, the handle 11 is mounted on the riser 12, and the height detection device includes:
[0026] A support platform 13, on which a positioning seat 14 is installed, and on which a circular hole 15 is provided, and in which the riser 12 is rotatably inserted;
[0027] A caliper 16, wherein the caliper 16 is vertically mounted on the supporting platform 13, and a push handle 17 is slidably provided on the caliper 16;
[0028] The measuring part 18 is fixed to the lower end of the push handle 17 and is used to measure the height of the handlebar.
[0029] The technical effect of this solution is that the height of the handlebars 11 on both sides of the handlebars can be accurately measured, so that it can be determined whether the heights of the two handlebars 11 are consistent, thereby achieving effective detection of the handlebar height.
[0030] Working principle: Insert the handlebar stem 12 into the circular hole 15 of the positioning seat 14, then manually rotate the stem 12 so that the handlebar 11 on one side is directly below the measuring part 18, and measure the height of the handlebar 11 on that side. Then, adjust the position of the handlebar and measure and record the height of the handlebar 11 on the other side. By comparison, it can be determined whether the heights of the handlebars 11 on both sides are consistent.
[0031] This solution realizes the positioning and rotation adjustment of the handlebars through the positioning seat 14, and the positioning seat 14 and the height detection device are both installed on the same support platform 13, so that the height of the handlebars on both sides can be detected by rotating the handlebars, which has the advantages of easy operation and high detection efficiency.
[0032] In addition, the circular hole 15 on the positioning seat 14 and the aperture of the seat tube 12 are consistent, and the seat tube 12 can just be inserted into the circular hole 15. In the same batch, if the seat tube 12 cannot be inserted into the circular hole 15, it can be detected that the handlebar does not belong to the product of this batch, thereby effectively avoiding the occurrence of mixing of materials.
[0033] This solution designs the installation form of the positioning seat 14, wherein one solution is: the positioning seat 14 is fixed on the supporting platform 13. Another solution is: the positioning seat 14 is detachably installed on the supporting platform 13.
[0034] Furthermore, the positioning seat 14 can be installed on the supporting platform 13 by bolts, which has the advantage of a simple connection form.
[0035] In other embodiments, Figure 2 and Figure 3 As shown, a limit groove 19 is provided at the lower end of the positioning seat 14, and a limit block 20 is fixed on the support platform 13, and the limit block 20 is used to be inserted and installed in the limit groove 19. The positioning seat 14 in this solution has the advantages of high disassembly efficiency and fast speed. When other batches of handles 11 are tested, only the corresponding positioning seat 14 needs to be replaced.
[0036] In addition, the positioning seat 14 has a certain height, and the handlebar must be taken and placed in the vertical direction to ensure that the vertical tube 12 at the lower end of the handlebar is not deformed. When the operator takes and places the handlebar in the vertical direction every time during a long-term test, it is difficult to ensure that the handlebar is taken and placed in the vertical direction every time. When it is taken and placed at an angle, the vertical tube 12 and the upper edge of the circular hole 15 of the positioning seat 14 will be squeezed, which will easily cause the vertical tube 12 to deform. In this embodiment, due to the connection method of the limit block 20 and the limit groove 19, the positioning seat 14 will fall off when the force is too large, thereby effectively protecting the vertical tube 12 of the handlebar.
[0037] As an implementation mode of this embodiment, the positioning seat 14 is cylindrical, the number of the limiting grooves 19 is multiple, and the multiple limiting grooves 19 are evenly distributed in a circular array based on the axis of the positioning seat 14, and the number of the limiting blocks 20 is the same as the number of the limiting grooves 19.
[0038] Furthermore, a rounded corner is provided at the upper end of the limit block 20. The technical effect of this solution is that the positioning seat 14 can be more conveniently assembled and disassembled.
[0039] As an implementation of this embodiment, the stop block 20 is a magnet. The positioning seat 14 is made of a metal material that can be attracted by a magnet, such as steel. The technical effect of this solution is to improve the stability of the installation of the positioning seat 14.
[0040] As an implementation method of this embodiment, Figure 4 As shown, an extension arm 21 is installed on one side of the measuring part 18, and an inserting part 22 is provided at one end of the extension arm 21, and the inserting part 22 is installed in the inserting port 23 of the measuring part 18. Further, a tightening screw 24 is provided on the measuring part 18, and the tightening screw 24 is used to lock the inserting part 22.
[0041] The technical effect of this solution is that the extension arm 21 is provided to ensure contact with the handlebar, thereby effectively detecting the height of the handlebar.
[0042] For ordinary technicians in this field, several modifications and improvements can be made without departing from the creative concept of the utility model, which all fall within the protection scope of the utility model.
