Embodiment Construction
[0012] refer to figure 1 The positioning and stretching fixture 1 includes a base 10, a stopper 20 slidably arranged on the base 10, two first springs 30, a handle 40, an adapter 50, two connecting rods 60 and a second spring 70, Wherein the adapter 50 is provided with a pressure head 53 . Driven by the above-mentioned mechanism, the pressure head 53 can press down and clamp the sealing rubber ring (not shown in the figure) and stretch it to a designated position, so that it can fit tightly to the housing (not shown in the figure) and facilitate installation .
[0013] together with reference figure 2 The base 10 includes a base 11, a linear guide rail 12 arranged on the base 11, a plurality of first limit blocks 13 arranged on both sides of the guide rail 12, support plates 14 spaced apart from each other protruding from both sides of the base 11, The fixing bar 15 fixed between the two supporting plates 14 and the second limiting blocks 16 located on both sides of the su...

Disclosed is a jig. The jig comprises a base, a stop block, a handle, a switching piece and a connecting rod. The base comprises a foundation part, a guide rail and a supporting plate, wherein the guide rail is arranged on the base, and the supporting plate is arranged at the side end of the foundation part in a protruding mode. The stop block is slidably arranged on the guide rail of the base and comprises an ejection face parallel to the guide rail. The handle comprises a handle part and a first support connected to the handle part. The end, away from the handle part, of the first support is connected to the supporting plate in a pivoting mode. The switching piece comprises an ejection plate, a second support and a pressing head arranged on the ejection plate, wherein the second support is connected to the ejection plate aslant by a certain included angle. The end, close to the ejection plate, of the second support is rotatably connected to the stop block. The two ends of the connecting rod are connected to the other end of the first support and the end, away from the ejection plate, of the second support respectively. When the handle is pressed, the pressing head can position an elastic silicon seal in a pressing mode so that the elastic silicon seal can be tensioned to an appointed position. By means of the jig, the silicon seal can be accurately and quickly tensioned to the appointed position so as to be conveniently installed.
Description
technical field [0001] The invention relates to the mechanical field, in particular to a fixture capable of positioning and stretching a sealing rubber ring. Background technique [0002] Electronic products, such as tablet computers, are usually provided with sealing rubber rings on the side ends of their casings to prevent light leakage and seal them. Since the sealing ring is relatively thin, long, narrow, and easily deformed and warped, the sealing ring cannot be tightly attached to the housing, which brings inconvenience to installation. Contents of the invention [0003] In view of this, it is necessary to provide a jig that can be stretched after relative positioning of the sealing rubber ring. [0004] The invention provides a positioning and stretching jig, which includes a base, a stopper, a handle, an adapter and a connecting rod. The base includes a base, a guide rail arranged on the base, and a protrusion on The support plate at the side end of the base, the...
