DETAILED DESCRIPTION

[0019] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0020] like Figure 1-3 As shown, the quick clamping device of the foldable truss for the reel sprinkler of this embodiment includes a first connecting plate 1 and a second connecting plate 2. One side of the first connecting plate 1 and the second connecting plate 2 is hinged by a rotating shaft 3, and the other side is provided with a locking device. The locking device includes a locating pin 4 arranged on the first connecting plate 1, a locking head 5 arranged on the second connecting plate 2 and used in conjunction with the locating pin 4, and a driving handle 6 is provided on the locking head 5. The driving handle 6 can drive the locking head 5 and the locating pin 4 to work separately, thereby adjusting the locking or opening state of the first connecting plate 1 and the second connecting plate 2. The structure is simple and the operation is convenient. Compared with the existing detachable connection method, the sprinkler truss can be quickly stored or unfolded, thereby improving the installation efficiency of the truss.

[0021] There are two rotating shafts 3. An adapter plate 7 for installing the rotating shaft 3 is provided on the inner side of the first connecting plate 1. An adapter angle 8 is provided at the connection between the adapter plate 7 and the first connecting plate 1. The adapter angle 8 is 120-135 degrees. The design of the adapter angle can ensure that the first connecting plate 1 and the second connecting plate 2 can be fully fitted in a closed state to avoid water leakage. At the same time, in order to improve the sealing performance, a clamping boss is provided at the lower part of the first connecting plate 1, and a sealing ring 16 is provided on the clamping boss. When the first connecting plate 1 and the second connecting plate 2 are fitted, the water pipes located on both sides of the clamping device will abut under the action of the clamping boss, and the sealing ring 16 can enhance the sealing of the connection between the two.

[0022] A sleeve 9 used in conjunction with the rotating shaft 3 is provided on the inner side wall of the second connecting plate 2. The rotating shaft 3 is inserted into the adapter plate 7 and the sleeve 9 so that the two can realize the function of rotating to open and close.

[0023] A hinge block 10 is provided at the front end of the driving handle 6, the upper part of the hinge block 10 is connected to the lock head 5, and the lower part is provided with a pin shaft 11 rotatably connected to the second connecting plate 2. After the rotation of the driving handle 6, the lock head 5 can be engaged or separated with the positioning 4, thereby realizing the locking or opening of the first connecting plate 1 and the second connecting plate 2.

[0024] There are two lock heads 5, which are respectively located at the upper and lower ends of the second mounting plate 2. A driving handle 6 is installed on each lock head 5, and a linkage rod 12 is provided between the two driving handles 6. The design of the linkage rod 12 can realize the synchronous operation of the two driving handles 6, while strengthening the connection state of the closed state, without the need for unnecessary operations.

[0025] The lock 5 includes a base plate 13, an end of which is provided with a hook 14 connected to the positioning pin 4, and the lower surface of the other end is provided with a avoidance groove 15 corresponding to the position of the pin shaft 11. The avoidance groove 15 is arc-shaped and fits with the outer wall of the pin shaft 11. In the locked state, the avoidance groove 15 fits with the outer wall of the pin shaft 11 to play a limiting role, thereby preventing the driving handle 6 from opening due to collision during operation.

[0026] During installation, two adjacent trusses are respectively installed on the back of the first connecting plate 1 and the second connecting plate 2. When it is needed, the second connecting plate 2 is rotated to make it fit with the first connecting plate 1. At this time, the water pipes of the two trusses are connected at the lower parts of the first connecting plate 1 and the second connecting plate 2, and the sealing strength of the connection is strengthened by the sealing ring 16 at the connection. Then, by rotating the driving handle 6, the locking head 5 and the positioning pin 4 are hooked to make the entire clamping device enter a locking state, ensuring that the entire truss is maintained in an open state. After the operation is completed, the driving handle 6 is reversed to separate the locking head 5 from the positioning pin 4, cancel the locking of the two connecting plates, and reversely rotate the second connecting plate 2 so that the truss connected to the second connecting plate 2 is folded inward and is parallel to the previous truss. At this time, the entire truss is in a folded state.
