Abstract
The utility model discloses a rotary joint locating angle lock of a movable joint carriage, which consists of a master locking plate 1, a rotary axis pin 2, an additional locking plate 3, concave points 7 annularly arranged on the master locking plate 1, a clearing hole 6 on the additional locking plate 3, a spring 5 in the clearing hole 6 and a locking head 4. After adopting the rotary joint locating angle lock, the movable joint carriage is good and elegant in appearance and is simple, lowers production cost and prolongs service life.
Description
(1) technical field
The utility model has related to a kind of rotary joint positioning angle locking that is used for movable joint bracing frame.
(2) technical background
Now the movable joint bracing frame of using mostly adopts the pull bar location, and therefore many pull bars on supporting frame make its cost of production higher and outward appearance is not attractive in appearance, and working life are also very short.
The purpose of this utility model is the short and high problem of cost of production for the working life of the positioning tie bar that solves movable joint bracing frame, and outward appearance is also had greatly improved.
(3) summary of the invention
The utility model rotary joint positioning angle locking is by passing through the hole and form by spring in the hole and locking head on the depression points of the annular array on main locking plate, rotating shaft pin, attached locking plate, the main locking plate, the attached locking plate.
The locking plate of the utility model rotary joint positioning angle locking can be a monolithic, also can be biplate.
Passing through the hole on depression points on the main locking plate of the utility model rotary joint positioning angle locking and the attached locking plate, can be that through hole or depression are held the hole.
The locking head of the utility model rotary joint positioning angle locking can be a hoodle, also can be the cylinder or the cone of fillet, can also be the spring sheet of distortion, also can also be little protruding cap.
The utility model rotary joint positioning angle locking simple in structure made easy.After movable joint bracing frame adopts rotary joint positioning angle locking, attractive in appearance, generous, succinct, reduced cost of production simultaneously, prolonged working life.
(4) description of drawings
Fig. 1, Fig. 2, Fig. 3, Fig. 4 are the main structure figure of the utility model rotary joint positioning angle locking.
Fig. 5 is the structure sectional view of Fig. 1, and Fig. 6 and Fig. 7 are that the structure of two kinds of patterns of Fig. 2 is analysed and observe.Fig. 8 is that the structure of Fig. 3 is analysed and observe, and Fig. 9 to Figure 11 is that the structure of three kinds of patterns of Fig. 4 is analysed and observe.
The utility model rotary joint positioning angle locking by main locking plate 1, rotating shaft pin 2, attached locking plate 3, locking head 4, On depression points 7 on spring 5, the main locking plate, the attached locking plate 3 pass through hole 6, by spring 5 and locking head 4 in the hole 6 Form.
(5) embodiment
The main locking plate 1 of the utility model rotary joint positioning angle locking and attached locking plate 3, combine by rotating shaft pin 2, the joint that has replaced supporting frame, main locking plate 1 and attached locking plate 3 are connected the end, joint of movable joint bracing frame respectively, and the locking heads 4 in the hole 6 of passing through on the attached locking plate 3 are absorbed under the promotion of spring 5 in the depression points 7 on the locking plate 1 and carry out locking.When main locking plate 1 and attached locking plate 3 relatively rotate, locking head 4 is retracted into by pressure spring 5 in the hole 6, along with main locking plate 1 and attached locking plate 3 continue to relatively rotate the position of needs the time, locking head 4 enters in the depression points 7 on the main locking plate 1 and carries out locking once more.
The utility model rotary joint positioning angle locking during fabrication; attached locking plate 3 can be processed into one with rotating shaft pin 2 (when main locking plate 1 is one chip); its structure is identical with structure of the present utility model and principle with principle, belongs to protection domain of the present utility model.
Claims (4)
