Next, please refer to the third figure to the tenth figure together, wherein, the sixth figure shows the operation lever and the first stopper in the operation lever assembly for preventing rotation during operation provided by the preferred embodiment of the present invention. The three-dimensional view of the stopper; the seventh figure is a schematic diagram showing the first stopper of the lever assembly for preventing rotation during operation provided by the preferred embodiment of the present invention; the eighth figure is the schematic diagram of the present invention A side view of the lever assembly for preventing rotation during operation provided by the preferred embodiment; Figure 9 shows the operation lever assembly for preventing rotation during operation provided by the preferred embodiment of the present invention. Partial top view of the operating lever after rotation; and, Figure 10 is a perspective view showing the operating lever assembly for preventing rotation during operation provided by the preferred embodiment of the present invention is pivoted to the chassis and moved into the chassis.

As shown in the figure, the operating lever assembly 1 is used for pivotally connected to the case 2, and allows the user to assemble the case 2 into the case 3 along the assembly direction D1.

When the operating lever assembly 1 is operated by the user and drives the chassis 2 to move outside the casing 3 along the assembly direction D1, the first stopper 122 is pressed against the first elastic element 123 along the first abutting direction D4, so that the first stopper 122 is pressed against the first pressing direction D4. A receiving groove T2 is not aligned with the side extending portion 112a. The operation lever 11 cannot rotate in the first direction D2 or the second direction D3 because the side extension portion 112 a is pressed against the first stopper 122 , as shown in the fifth and sixth figures. Therefore, the present invention solves the hand-pinch problem caused by the possible rotation of the handle PA13 along the first direction D2 or the second direction D3 during the movement in the prior art.

When the operating lever assembly 1 is operated by the user to drive the chassis 2 to move into the casing 3 along the assembly direction D1, the inner walls on both sides of the casing 3 will gradually press against the first stopper along the first guide surface S1 and compress the first stopper. 122. At the same time, the first stopper 122 moves along a first compression direction D5 and compresses the first elastic element 123 .

When the first stopper 122 is moved to align the first receiving groove T2 with the side extension 112a, as shown in FIG. 7, the operating rod 11 can be rotated in the first direction D2, as shown in FIG. 8 Show. In this embodiment, when the inner wall of the casing 3 abuts against the first abutting surface S2, the first stopper 122 will not move any more, and the first receiving groove T2 at this time will be aligned with the side edge Extension 112a.

After the operating rod assembly 1 drives the chassis 2 to move into the chassis 3 along the assembly direction D1 , the first pivoting recess O1 of the side extension 112 a covers a first pivoting member in the chassis 3 . It should be noted that the chassis 2 and the chassis 3 in this embodiment and the chassis PA11 and the chassis PA12 in the prior art are the same. Therefore, although the drawings do not draw the first pivoting member in the chassis 3, it can be Please refer to the pivot member PA121 in the casing PA12 in the second figure, both of which are the same component.

Then, the user can rotate the operating rod 11 along the first direction D2. Because the first receiving groove T2 is aligned with the side extension 112a and the first pivoting notch O1 covers the first pivoting member in the casing 3, the user can make the operating lever 11 use the first pivoting member In order to rotate the fulcrum, it is rotated into the first accommodating groove T2 and the first accommodating groove T1, as shown in the ninth figure, thereby achieving the effect of saving labor. At the same time, the user can fix the case 2 in the case 3, as shown in the tenth figure. The present invention solves the problem in the prior art that the handle PA13 may rotate along the first direction D2 or the second direction D3, so that the pivoting recess PA131 cannot be aligned with the pivoting member PA121 when the chassis PA11 is moved into the casing PA12, so that the The problem of pivoting PA121 as a fulcrum.

In addition, the first stop sub-assembly 12 is used to describe and illustrate the above, and the operation principle of the second stop sub-assembly 13 is basically the same. The only difference is that the second stop sub-assembly 13 is pivotally connected and corresponds to the side extension portion 112b, and because the second stop sub-assembly 13 and the first stop sub-assembly 12 are located on the left and right sides, respectively, the second stop sub-assembly 13 The direction of operation of the assembly 13 is also different from that of the first stop subassembly 12 . To put it simply, a second abutting direction of the second elastic element is opposite to a first abutting direction D4 of the first elastic element 123 , and the second stopper is pressed against by the casing 3 to compress a portion of the second elastic element. The second compression direction will be opposite to the first compression direction D5.

In addition, the above is only a preferred embodiment of the present invention. In other embodiments of the present invention, the operating lever assembly 1 only includes the first stop sub-assembly 12 or only includes the second stop sub-assembly 13, which can also be implemented accordingly. , and solve the problems of the prior art, and achieve the above effects.

To sum up, in the operation lever assembly for preventing rotation during operation provided by the present invention, the first stop sub-assembly can prevent the operation lever from rotating during operation. Compared with the prior art, the present invention has Preventing the operation lever from rotating during operation can avoid safety problems such as pinching hands. In addition, it can also ensure that when the chassis is moved into the casing, the first pivoting notch can align and cover the first pivoting piece. In addition, the first pivot member is used as a fulcrum to rotate, thereby achieving the effect of saving labor, and at the same time, the box can be assembled and fixed in the casing.
