Description

Universal magnetic seat with angle adjustment constant force mechanism and locking

The invention has an angle adjusting constant force mechanism and a locking universal magnetic seat, and is mainly used for avoiding damage of internal components caused by excessive external force during locking, and technically ensuring measurement accuracy after locking.

According to the angle adjustment and fixing device of the conventional magnetic seat, please refer to the first figure: the sectional combination diagram of the system. The main function is: an angle adjustment and fixing device is fixed between the magnetic base 10 and the measuring gauge 80, and the angle adjusting and fixing device is disposed at the upper end and the lower end of the two mutually coupled connecting rod arms 1, 1' Two adapters 2, 2', and two ball shafts 3, 3' are arranged inside the two adapters 2, 2', and the two ball shafts 3, 3' are locked and fixed to the magnetic base 10 and the measuring scale 80. The two ball shafts 3, 3' are controlled by two ball sockets 4, 4' and two pressing rods 5, 5', and a sliding shaft rod is disposed at the pivot joint of the adapter rod arms 1, 1'. 6. A gasket O, a sliding sleeve 7, and a rotary knob 8 at the outer end of the sliding shaft 6, and grooves 6', 7' are formed on the sliding shaft 6 and the sliding sleeve 7, Let the grooves 6', 7' slide in the pressing rods 5, 5'; when the rotating button 8 is tightened, the sliding shaft 6 and the sliding sleeve 7 are inwardly closed, so that the pressing rods 5, 5' on both sides are along The grooves 6', 7' climb up to a high point, and then use the pressing rods 5, 5' to firmly hold the ball sockets 4, 4' against the ball shafts 3, 3' to form a fixed state; 8 When the loosening, the sliding shaft 6 and the sliding sleeve 7 are moved outward to make the two sides Pressing the rods 5, 5' back to the low point of the grooves 6', 7', letting the ball sockets 4, 4' The loose ball shafts 3, 3' form an adjusted state; at the same time, the measuring gauge 80 and the ball shaft 3' are provided with two rotating wheels 9, 9' as an angle between the measuring gauge 80 and the ball shaft 3'. .

However, the angle adjustment and fixing device of the above-mentioned conventional magnetic seat has at least the following problems and defects that need to be solved in practical application:

1. Because the rotary button 8 of the outer end of the sliding shaft 6 is locked, there is a thread gap between the two, which causes the button 8 to be unlocked, and when the button 8 is locked too hard, too When it is tight, its internal components are easily damaged.

2. Since the pressing rods 5, 5' are not provided with elastic members, when the rotary button 9 is loosened, the pressing rods 5, 5' on both sides do not necessarily automatically return to the low points of the grooves 6', 7', resulting in The angle adjustment action is not correct, the accurate angle adjustment cannot be obtained, the stability is not good, the stable combination relationship cannot be obtained, and the situation of sloshing is easy to occur, which directly affects the accuracy of the measurement of the scale.

The inventor is currently engaged in the manufacture and design of related products, and has accumulated many years of practical experience and experience. In view of the existing problems and lack of the angle adjustment and fixing device of the above magnetic seat, the inventor actively invested in the spirit of innovation and improvement, and completed the The angle adjustment mechanism and the locked universal magnetic seat.

The technical means for solving the problem and the effect of the prior art are that the magnetic seat and the measuring gauge are each locked with a universal joint and a movable rod, and the two movable rods are provided with pivoting portions which are pivotally connected to each other. The pivoting portion is provided with a radial hole, wherein a radial hole of a movable rod can accommodate a bushing, and a radial hole of the other movable rod can be provided with a bolt, and the bolt is locked by a knob a flat thrust bearing and a coupling member are disposed on the outer side of the bushing, and the flat thrust shaft is utilized The bearing knob is more smoothly and smoothly locked, and the friction between the bushing and the bushing is reduced, and the bushing can be prevented from rotating along with the knob. The connecting member is provided with the first and second capacities corresponding to the bushing and the knob. The slotting mechanism is configured to provide a constant force mechanism, the force determining mechanism includes a first disc type washer and a second disc type washer. When the knob is locked, the outer diameter of the second disc type washer is the second capacity The inner diameters of the grooves are abutted against each other, and the force and the reaction force formed by the second disc type gasket enable the nut of the knob to be tightly pressed against the thread of the bolt, thereby eliminating the gap of the screw. At the same time, the locking force of the knob can be set to avoid damage to the internal components caused by the knob being locked too tightly, and the efficiency is improved, and the main purpose is achieved.

The technical means applied by the invention solves the problem 2 and the efficacy of the prior art is that the magnetic seat and the measuring gauge are each locked with a universal joint, and the other end of the universal joint is provided with a sphere, and the ball system is provided for adjustment. The adjusting member is internally provided with a ball socket and a sleeve, the sleeve is locked at one end of the movable rod, and the other end of the movable rod is provided with a pivoting portion pivoted to each other, and the pivoting portion is provided with a radial direction a hole, wherein a radial hole of a movable rod can accommodate a bushing, and a radial hole of the other movable rod can be provided with a bolt and locked by a knob, and the movable rod is provided with a radial hole a through hole, the axial hole is adapted to pass through the ejector rod and the linkage rod, and an elastic element is sleeved in the linkage rod, and the ejector rod is provided with a circular arc convex portion corresponding to the radial hole, The bushing and the bolt are provided with a circular arc concave portion corresponding to the arc convex portion of the ejector pin. When the knob is tightened, the bushing and the bolt are simultaneously displaced inward, and the circular arc concave portion of the bushing and the bolt is used for the two ejector pins. The arc convex portion generates a pushing action, so that the two linked rods can drive the two spheres of the two ball sockets to the two universal joints The pressing action of the pressing force allows the two movable rods to fix the measuring scale to an appropriate measuring angle. Since the connecting rod is provided with an elastic member, the connecting rod can be accurately actuated, and the stability is good, and no shaking occurs. The situation ensures the accuracy of the measurement; there is an increase in efficacy, reaching for its secondary purpose.
