Detailed Description
Referring to fig. 1 to 4, an embodiment of the fixing device of the present invention is illustrated, in which the fixing device includes two adjustable limiting mechanisms 100, and is adapted to be installed on a loading structure 101 at an adjustable position. In this embodiment, the top side of the fixing device can be used in cooperation with clamping arms and other mechanisms not shown in the drawings to fix printed circuit boards with different dimensions. The loading structure 101 is illustrated as a rod-shaped structure, and the fixing device can slide on the loading structure 101 after the locking state is released, so as to be matched with printed circuit boards with different sizes for processing. In the present embodiment, the adjustable limiting mechanism 100 is implemented in a left-right mirror symmetry manner, and the two are connected by a mechanism not described in detail for use in cooperation. According to various embodiments, the fixing device can also be implemented by one or more of any number of adjustable limiting mechanisms 100, and the type of the loading structure 101 is not limited to a rod-like structure, and thus is not limited to a specific embodiment. For clarity of explanation of the present embodiment, the following description will be given mainly with reference to the adjustable stopper mechanism 100 located on the right side of the drawing.
Referring to fig. 2 to 5, each adjustable limiting mechanism 100 includes a first locking structure 1, a second locking structure 2 and an elastic element 3.
The first locking structure 1 is, for example, a plate-shaped structure made of a metal material, and a first locking hole 11 is formed through the first locking structure, and the first locking hole 11 is suitable for the loading structure 101 to penetrate through. The second locking structure 2 is, for example, a plate-shaped structure made of metal, and one side (top side in the figure) of the second locking structure is pivoted to the first locking structure 1, so that the second locking structure 2 can pivot relative to the first locking structure 1. The second clamping structure 2 penetrates through to form a second clamping hole 21 corresponding to the first clamping hole 11, the size of the second clamping hole 21 is different from that of the first clamping hole 11, and the second clamping hole 21 is suitable for being penetrated and extended by the loading structure 101 together with the first clamping hole 11. The elastic element 3 is connected to the first engaging structure 1 and the second engaging structure 2, and provides an elastic force for pivoting the second engaging structure 2 in a direction away from the first engaging structure 1, so that a part of the hole edge of the second engaging hole 21 is engaged with the loading structure 101. Accordingly, the positive force and the friction force formed by the engagement between the hole edge (the bottom hole edge in fig. 5) of the second engaging hole 21 and the loading structure 101 can limit the relative movement between the adjustable position-limiting mechanism 100 and the loading structure 101, so that the fixing device shown in fig. 3 to 5 can be set to the locking state, and the fixing device cannot move on the loading structure 101. Of course, according to the size of the first locking hole 11, in the locked state, the hole edge of the first locking hole 11 may also be configured to be similarly locked on the loading structure 101, so that the hole edges of the first locking hole 11 and the second locking hole 21 are both locked on the loading structure 101, and the fixing effect can be further ensured.
Referring to fig. 1, 6 to 8, the second fastening structure 2 includes a pivot portion 22 pivotally connected to the first fastening structure 1, and a pressing portion 23 located on two opposite sides of the second fastening hole 21 and the pivot portion 22 respectively. The pressing portion 23 is adapted to be pressed by a device (not shown in the drawings), so that the second locking structure 2 can pivot toward the first locking structure 1 by overcoming the elastic force of the elastic member 3 as shown in fig. 6 to 8, and the edges of the second locking hole 21 and the first locking hole 11 are not locked to the loading structure 101. In this way, the locking state of the fixing device can be released, so that the fixing device can be moved freely on the loading structure 101 to adjust the size of the printed circuit board to be processed.
Referring to fig. 1 to 3 and 5, in the embodiment, the cross-sectional size of the hole of the first locking hole 11 is slightly larger than the cross-sectional size of the loading structure 101, and the cross-sectional size of the hole of the second locking hole 21 is larger than the cross-sectional size of the hole of the first locking hole 11. The first locking hole 11 and the second locking hole 21 have the same shape, and the shape may be selected from one of a circle, a square, or other polygon, which is illustrated as a square in the figure, and the shapes of both are the same as the cross section of the loading structure 101. Since the hole cross-sectional dimension of the second locking hole 21 is configured to be larger than the hole cross-sectional dimension of the first locking hole 11, the second locking structure 2 is ensured to have a certain movement space when pivoting, but still can provide a locking and limiting effect by the edge of the second locking hole 21 when being locked against the loading structure 101. In a different embodiment, the first locking hole 11 and the second locking hole 21 may be different in shape, and at least one of the two holes may be locked by the mounting structure 101 to play a fixing role.
Referring to fig. 1 to 4, the adjustable limiting mechanism 100 further includes a supporting structure 4 protruding from an inner side of one of the first locking structure 1 and the second locking structure 2 to the other of the first locking structure 1 and the second locking structure 2. In this embodiment, the supporting structure 4 protrudes from the inner side of the second fastening structure 2 to the first fastening structure 1. Therefore, after the second locking structure 2 pivots towards the direction close to the first locking structure 1, the supporting structure 4 will support between the first locking structure 1 and the second locking structure 2, so that the second locking structure 2 cannot continue to pivot towards the first locking structure 1. In this way, after the second locking structure 2 is pressed towards the first locking structure 1, the supporting structure 4 can provide a supporting function between the first locking structure 1 and the second locking structure 2, so as to prevent the second locking structure 2 from being excessively pressed, thereby providing a structural protection function. In addition, in this embodiment, the elastic element 3 is a torsion spring disposed at the pivot joint of the first locking structure 1 and the second locking structure 2, and two ends of the torsion spring are respectively connected to the first locking structure 1 and the second locking structure 2, so as to provide an elastic force required for maintaining the locking state of the fixing device and the adjustable limiting mechanism 100. However, the elastic member 3 may be a member other than a torsion spring as needed, and is not limited to the disclosure of the embodiment.
In summary, the fixing device of the present invention can be configured in size by the first engaging hole 11 of the first engaging structure 1 and the second engaging hole 21 of the second engaging structure 2, or further by the shape design of the two, so that the first engaging structure 1 and the second engaging structure 2 are driven by the elastic force of the elastic member 3, and at least the hole edge of the second engaging hole 21 is engaged with the loading structure 101, thereby achieving the limiting and fixing effect. When necessary, the locking state can be released by pressing the second clamping structure 2, so that the operation is simple and convenient, the structure is simple and uncomplicated, and the operation of cost control and maintenance and part replacement is facilitated. Therefore, the fixing device and the adjustable limiting mechanism 100 of the present invention can achieve the objective of the present invention.
