DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1 - Figure 5 As shown, the utility model is a ball screw for adjusting a car seat, comprising a ball screw body 1, a clamping assembly 2 is provided on one side of the ball screw body 1, a screw sleeve assembly 3 is provided on the outer surface of the clamping assembly 2, a latch 4 is provided inside the screw sleeve assembly 3, and a threaded rod 5 is provided at one end of the latch 4.

[0026] The clamping assembly 2 includes a connecting rod 201, a plug 202, a limit plate 203 and a threaded groove 204. The plug 202 is fixedly installed at one end of the ball screw body 1, and the limit plate 203 is fixedly installed on the peripheral side of the plug 202. The number of the limit plates 203 is fixed to four, and a threaded groove 204 is opened at one end of the plug 202 away from the ball screw body 1.

[0027] The screw sleeve assembly 3 includes a screw sleeve shell 301, a maintenance hole 302, a limiting groove 303, a refueling hole 304 and a sealing plug 305. The outer surface of the screw sleeve shell 301 is provided with a plurality of maintenance holes 302, and the inner wall of the screw sleeve shell 301 is provided with a limiting groove 303. The number of the limiting grooves 303 is fixed at four, and the limiting grooves 303 are snap-connected with the limiting plate 203. The outer surface of the screw sleeve shell 301 is provided with a refueling hole 304, and the refueling hole 304 is connected with the interior of the screw sleeve shell 301. The inner wall of the refueling hole 304 is provided with a sealing plug 305.

[0028] A latch 4 is disposed inside the screw rod housing 301 .

[0029] A threaded rod 5 is fixedly mounted on one end of the latch pin 4 , and the threaded rod 5 is threadedly connected to the thread groove 204 .

[0030] A baffle plate 6 is fixedly mounted on the peripheral side of the latch pin 4 . The baffle plate 6 abuts against the screw housing 301 . A hexagon socket disassembly end 7 is fixedly mounted on one side of the baffle plate 6 .
