The utility model relates to a kind of position limiting structures, especially a kind of bulb Universal rotary position limiting structure, including bulb, bulb bottom cover, bulb pressing plate and steel ball, the bulb pressing plate is mounted on the top of bulb bottom cover, bulb is mounted on bulb bottom cover, and the spherical part of bulb is located in the diameter of Spherical Volume that bulb bottom cover and bulb pressing plate are formed；The top of bulb is equipped with track groove, and the inner wall of bulb pressing plate is equipped with limiting slot, and the steel ball is placed between track groove and limiting slot.The utility model does not have to excessive cumbersome structure; both it had been able to satisfy the angle rotation demand that bulb connects lower operational module; it can limit that operational module is avoided excessively to rotate around bulb again, to protect the circumscripted power line and data line on operational module, meet design use demand.
Description
Technical field
The utility model relates to a kind of position limiting structure, especially a kind of bulb Universal rotary position limiting structure.
Background technique
When the operational module of bulb connection makees universal rotational rotation, the meeting such as external power supply line, data line on operational module
It reverses, rotate with rotation, do not damaged because crossing big angle rotary for protection power source line, data line, therefore it is universal to design bulb
Rotation limiting structure scheme.
Summary of the invention
The utility model is intended to provide a kind of bulb Universal rotary position limiting structure, its transition rotation is avoided to cause operational module
The damages such as upper external power supply line, data line.
According to the technical solution of the utility model, the bulb Universal rotary position limiting structure, including bulb, bulb bottom cover,
Bulb pressing plate and steel ball, the bulb pressing plate are mounted on the top of bulb bottom cover, and bulb is mounted on bulb bottom cover, the ball of bulb
Shape part is located in the diameter of Spherical Volume that bulb bottom cover and bulb pressing plate are formed；The top of bulb is equipped with track groove, bulb pressing plate
Inner wall is equipped with limiting slot, and the steel ball is placed between track groove and limiting slot.
Further, the track groove in the shape of a spiral, is set to the top center of bulb.
Further, the angle of circumference of the track groove is 360-450 °.
Further, the limiting slot is laterally arranged along the arc inner wall of bulb pressing plate, through the inner wall of bulb pressing plate.
Further, the bulb bottom cover is equipped with mounting groove, and the lower end of bulb pressing plate is protruded into mounting groove.
The utility model has the beneficial effects that: not having to excessive cumbersome structure, bulb both it had been able to satisfy and has connected lower Working mould
The angle of block rotates demand, and can limit that operational module is avoided excessively to rotate around bulb, to protect on operational module
Circumscripted power line and data line, meet design use demand.
Detailed description of the invention

Specific embodiment
The utility model is described in further detail with attached drawing combined with specific embodiments below.
It is as shown in the figure: bulb Universal rotary position limiting structure, including bulb 4, bulb bottom cover 3, bulb pressing plate 2 and steel ball 1, ball
Head pressing plate 2 is mounted on the top of bulb bottom cover 3, and bulb 4 is mounted on bulb bottom cover 3, and the spherical part of bulb 4 is located at bulb bottom
In the diameter of Spherical Volume that lid 3 and bulb pressing plate 2 are formed, bulb bottom cover 3 is stretched out for connecting operational module in the lower end of bulb 4.
It is equipped with track groove 4.1 at the top of bulb 4, the inner wall of bulb pressing plate 2 is equipped with limiting slot 2.1, for cooperating steel
Pearl movement, steel ball 1 are placed between track groove 4.1 and limiting slot 2.1.
Specifically, track groove 4.1 is in the shape of a spiral, it is set to the top center of bulb 4, the angle of circumference of track groove 4.1 is
360-450 °, to meet work rotation angle needs.Limiting slot 2.1 is laterally arranged along the arc inner wall of bulb pressing plate 2, runs through ball
The inner wall of head pressing plate 2.Bulb bottom cover 3 is equipped with mounting groove, and the lower end of bulb pressing plate 2 is protruded into mounting groove, and installation reliability is high.
When bulb 4 rotates, steel ball 1 can meet the track groove movement that work rotation angle needs on bulb 4；And ball
Head pressing plate 2 is equipped with the limiting slot 2.1 of the lateral arc of cooperation steel ball above, and limitation steel ball 1 can only move in track groove；Track
The operational module that slot circumferential angle connects bulb goes down from the rotation of ceaselessly contiguous circumferential, and the angle that maximum is pivoted is
The angle of circumference of track groove, is 390 ° in diagram, is limited when all around rotating (universal rotational) by bulb pressing plate 2, angle is
40 °, the part provided in the diameter of Spherical Volume that bulb bottom cover and bulb pressing plate are formed on bulb pressing plate is bigger, and rotatable angle is got over
Greatly；The not too big circle rotation of power supply line, data line in this way on operational module and protected.
