Detailed description of the invention
Below in conjunction with embodiment, the utility model will be further described.
In the drawings, one of the present utility model anti-loosening be locked pipe clamp mainly by lower clamp 1, upper clamp 2, connect screw rod 3,
Locking device 4, nut draw-in groove 5, installation endoporus 6, locking top 7, latch 8, expanding sheath 9, lower nut 10, upper spiral shell
Mother 11, stop screw rod 12 form.
Described compound tube folder includes lower clamp 1, upper clamp 2, connects screw rod 3, locking device 4；Described lower clamp 1, upper folder
Connected by connection screw rod 3 between body 2；The bottom of described lower clamp 1 is provided with nut draw-in groove 5；Described connection screw rod 3
Nut is installed in nut draw-in groove 5；The upper end of described connection screw rod 3 is provided with locking device 4；Described locking device 4 is by pacifying
Dress endoporus 6, locking top 7, latch 8, expanding sheath 9, lower nut 10, top nut 11, stop screw rod 12 form；Institute
The upper end stating connection screw rod 3 offers installation endoporus 6；In described installation endoporus 6, stop screw rod 12 is installed；Described stop spiral shell
