Abstract

1. A hinge joint made in the form of a ball bearing, including an open outer casing and a swivel head, characterized in that the swivel head is mounted on the rod and equipped with a locking mechanism, which includes a rod, a stopper lever attached to the rod, a spring and a brake shoe, and in An open outer casing is fitted with a stabilizer consisting of a casing with a stabilizer hinge in the center and a stabilizer spring, while the unclosed outer casing is connected to the rod. 2. The articulated joint according to claim 1, characterized in that the rod and the rod are made with a threaded joint.

Description

The utility model relates to the field of mechanical engineering, namely to the mechanical assembly of mating parts and assemblies that provide the ability to fix parts.

Known ball joint comprising a housing, a heel connected to a movable element and provided with an annular ridge; a movable thrust bearing made in the form of a hemisphere with a groove and a protrusion and mounted in the casing (SU 389301, publ. 1973. F16C 11/06).

The disadvantage of this hinge is the inability to automatically move and fix the heel with a movable element, which significantly limits the scope of the known hinge.

Known ball joint containing a finger with a ball head placed on it with liners installed in the housing. Installed in the ball head from the side opposite the finger, the cavity, and a compression spring located between the glass and the bottom of the cavity (SU 1739099. 06/06/1992. F16C 11/06). The disadvantage of this hinge is the design complexity and therefore the likelihood of structural failure increases. The lack of rotation of the head.

The closest in technical essence to the claimed technical solution is a ball joint containing a ball head and an open loop housing. The housing is made in the form of a bracket covering the ball head (RU 2068500, publ. 10.27.1996. F16C 11/06). The disadvantages of this device are the lack of the possibility of a fixed installation of the rotary head and the inability to return the rod to its original position.

The technical task of the claimed utility model is the creation of a device that can significantly expand the possibility of using a ball joint, with the possibility of fixing in a given position the details of the connection.

The technical result achieved by using the claimed utility model is expressed in the acceleration and simplification of the change of position of the rotary head of the ball joint in the range from 0 to 150 °, which is achieved due to the quick and accurate installation of the parts of the ball joint in a given position with subsequent fixation of the position.

The technical result of the claimed utility model is achieved by the fact that the swivel is made in the form of a ball bearing, including an open outer casing and a rotary head. The swivel head is mounted on the rod and is equipped with a locking mechanism including a rod, a stopper lever mounted on the rod, a spring and a brake shoe. In the open outer casing, a stabilizer is installed consisting of a casing in the center of which a stabilizer hinge is located, and springs. In this case, the open outer casing is connected to the rod.

The rod and rod are threaded.

The drawings show:

Figure 1 - ball joint in the initial position

Figure 2 - ball joint movement of the rotary head

Figure 3 - ball joint operation of the stabilizer

The figures depict the claimed device comprising a rod (1) connected to the hinge body (2). At the opposite end of the threaded thread (14). Inside the open housing there is a stabilizer (5), a stabilizer hinge (3), a stabilizer spring (4). A rod (11) with a brake shoe (12) fixed at one end and a threaded connection (14) at the other end passes through the pivoting head of the hinge (6). A stop lever (10) is mounted on the stem (11). The stopper lever (10) rests against the protrusion (7) against the protrusion (7) and affects the spacer spring (13) mounted on the rod (11).

Use ball connection as follows. To set the ball joint to the required position, move the stopper lever (10). In this case, the nose of the stopper handle (8) rests on the axis (9) and affects the spacer spring (13) which is compressed (figure 2). The rod (11) with the brake shoe (12) moves away from the stabilizer body (5) allowing free movement of the hinge head (6), thereby exposing the rod (11) to the desired position (figure 2). After releasing the stopper knob (10), the brake shoe (12) under the reverse action of the force of the spacer spring (13) abuts against the stabilizer and firmly fixes the set position. The range of the angle of the parts is from 0 to 150 °.

The principle of action of the stabilizer is that after the application of force to the rod (11), it deviates. The stabilizer taper spring (4), under the influence of the stabilizer body, briefly takes a compressed position (Fig. 3) deviating in the direction of the applied force from a given axis to 35 °, and under the influence of the reverse spring force (4) returns the rod (11) to its original position. The stabilizer spring dampens inertial oscillatory movements and, if necessary, can work on twisting.

The utility model can be manufactured using standard industrial equipment.
