Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Referring to fig. 1-6, a splicing type fence comprises a fixing rod 1 (referring to fig. 1-6, the number of the fixing rod 1 is two, which facilitates the explanation of the installation and use process), wherein one side of the fixing rod 1 is provided with a first groove 2, the other side of the fixing rod 1 is provided with a sliding groove 3, the first groove 2 is communicated with the sliding groove 3, the fixing rod 1 at the first groove 2 is provided with a second groove 4, the first groove 2 is spaced from the second groove 4, the sliding groove 3 is communicated with the second groove 4, the fixing rod 1 at the second groove 4 is fixedly provided with two connecting rods 5 through bolts, one ends of the two connecting rods 5 far away from the second groove 4 are provided with a fixture block 6 through fixing bolts (the fixture block 6 arranged here is placed inside the first groove 2 in the splicing process), the fixture block 6 is in clearance fit with the first groove 2, the middle of second recess 4 is installed pivot 7 through the bearing, fixed mounting has gear 8 on the pivot 7 in the inside of second recess 4, spout 3 is close to and has placed movable block 9 in the first recess 2, clearance fit between movable block 9 and the spout 3, spout 3 keeps away from movable block 9 one side card and is equipped with fixed block 11, the butt has spring 12 between fixed block 11 and the movable block 9, movable block 9 is close to gear 8 one side and has seted up rack 10, gear 8 meshes with rack 10 mutually, the inside fixture block 6 of first recess 2 is run through by movable block 9, fixed mounting has handle 13 on the pivot 7 in the second recess 4 outside. Through setting up clearance fit between movable block 9 and the spout 3, convenient back is through the rotation of gear 8, lets inside movable block 9 inserts fixture block 6, avoids the inside fixture block 6 of first recess 2 to break away from first recess 2, leads to the device combination failure. Through setting up clearance fit between fixture block 6 and the first recess 2, let first recess 2 inject the size of fixture block 6, conveniently carry on spacingly to the position of fixture block 6 to the cooperation of being convenient for lets movable block 9 insert inside fixture block 6.
