It not only extends the service life of machine tools and guide rails, but also improves production efficiency and operational safety.

[0003] Common guide rail telescopic shields are directly installed on the track slider and extend and retract as the track slider slides. This installation method requires frequent extension and retraction of the track shield, and its connecting spring parts are prone to damage. Tracks of different lengths need to be replaced with shields of corresponding telescopic lengths, which is relatively troublesome to operate. Secondly, the shield has a maximum extension length and a compression length, which imposes certain restrictions on the sliding range of the track slider, reducing the usability of the shield.

[0016] The technical solution of the utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0017] Example

[0018] like Figure 1-3As shown, the utility model proposes a guide rail telescopic shield that is easy to install, comprising a track base plate 1 and a sliding shield 2, a track body 3 is fixed at the middle position of the upper end of the track base plate 1, a track plate 31 is slidably connected to the upper end of the track body 3, a track connecting column 32 is fixed to the upper end of the track plate 31, the sliding shield 2 is slidably connected to both sides of the track base plate 1, and is symmetrically distributed, the sliding shield 2 is close to one side and abuts against each other, a telescopic rod 22 is fixed to the outer side of the bottom of the sliding shield 2, telescopic grooves 11 are opened on both sides of the track base plate 1 and at positions corresponding to the telescopic rod 22, the end of the telescopic rod 22 is slidably connected in the telescopic groove 11, a driving component 4 is arranged between the track plate 31 and the track base plate 1, a rubber pad 21 is fixed to one side of the upper end of the sliding shield 2, and the upper end is inclined toward the outside, a guide groove 12 is opened at the upper end of the track base plate 1 and at a position corresponding to the sliding shield 2, a guide block 23 is fixed to the bottom of the sliding shield 2 at a position corresponding to the guide groove 12, and the guide block 23 is slidably connected in the guide groove 12.

[0019] The drive assembly 4 includes a drive slot 43 and a mounting plate 41. The mounting plate 41 is fixed to the front and rear sides of the track plate 31 and is symmetrically distributed. The drive slot 43 is opened at the upper end of the track bottom plate 1 and is aligned with the telescopic slot 11. A fixed tooth plate 42 is fixed to the bottom of the mounting plate 41. A drive gear 44 is rotatably connected in the drive slot 43. The upper end of the drive gear 44 extends out of the drive slot 43 and meshes with the fixed tooth plate 42. The outer wall of the drive slot 43 is communicated with the telescopic slot 11, and a reciprocating screw rod 45 is rotatably connected in the telescopic slot 11. A threaded sleeve 46 is threaded on the reciprocating screw rod 45, and the threaded sleeve 46 is fixed to the end of the telescopic rod 22. The driving gear 44 can be driven to rotate by sliding the fixed tooth plate 42. After the front fixed tooth plate 42 and the rear fixed tooth plate 42 slide over the top of the drive slot 43 once, the reciprocating screw rod 45 can be driven to rotate at a specified angle, thereby causing the threaded sleeve 46 to perform a single reciprocating motion.

[0020] When the track plate 31 slides on the track body 3, the mounting plate 41 at the front end of the track plate 31 will pass over the driving groove 43 in advance. At this time, the corresponding fixed tooth plate 42 at the bottom meshes with the driving gear 44 for transmission, driving the reciprocating screw rod 45 to rotate, so that the threaded sleeve 46 slides outward, and finally drives the sliding shield 2 to slide outward. At this time, when the track plate 31 slides to this position, the sliding shield 2 at this position slides to both sides, so that the track connecting column 32 can pass smoothly, and after sliding, the fixed tooth plate 42 on the rear side of the track plate 31 is used to drive the driving gear 44 and the reciprocating screw rod 45 to rotate again, and the threaded sleeve 46 and the telescopic rod 22 will be driven to slide inward, thereby closing the sliding shield 2 of the same group to protect the track body 3. In this case, the sliding shield 2 will not occupy the telescopic space of the track body 3. A specified number of sliding shields 2 can be installed according to the length of the track of different lengths, and there is no corrugated structure to avoid the accumulation of foreign matter and dust, and the operation is simpler.

[0021] The above-mentioned specific embodiments are only several preferred embodiments of the present invention. Based on the technical solution of the present invention and the relevant inspiration of the above-mentioned embodiments, those skilled in the art can make various alternative improvements and combinations to the above-mentioned specific embodiments.
