As shown in fig. 1 to 4, the small linear module comprises a section bar 1 and a screw rod 2 arranged in the section bar 1, wherein the top of the section bar 1 is sealed by steel belts 4 fixed at two ends, and two sides of each steel belt 4 are magnetically connected with the section bar 1. Be connected with integral type slider mechanism 3 on lead screw 2, integral type slider mechanism 3 includes lead screw slider 31, steel band slider 32 and load connecting seat 33 that fixed connection is as an organic whole, and lead screw slider 31 cup joints with lead screw 2 screw thread, and steel band slider 32 extends behind the section bar 1 with 4 butts of steel band, and load connecting seat 33 is located the steel band 1 outside, is provided with the rete on lead screw slider 31 and the 1 sliding connection of section bar and the sliding fit face.

In a linear module, the top of the profile needs to be provided with an opening to allow the internal slider to be connected to the load connection socket, which is used to connect the load driven by the linear module and must be located outside the profile. In the fields of food, medical treatment and the like, the requirement on the cleanliness of equipment is high, and engine oil and the like on screw transmission cannot leak, so that the screw transmission part needs to be well sealed. In this scheme, come the opening at 1 top of sealing section bar through steel band 4, the both ends and the 1 fixed connection of section bar of steel band 4, the both sides of steel band 4 (two edges along width direction are referred to the steel band) are connected with section bar magnetism, magnetism is connected and is made steel band 4 and section bar 1 can be together fixed on the direction of height, and on length direction, do not have magnetic force, can not interfere integral type slider mechanism 3 again and follow the ascending removal of length direction, when guaranteeing to remove smoothly, can guarantee the inside leakproofness of section bar again.

The distance of steel band slider 32 ejecting out section bar 1 top surface can be temporarily be separated steel band 4 and section bar 1 thereby leave the interval and let the connection structure between load connecting seat 33 and the steel band slider 32 pass through, and steel band slider 32 just plays the effect that produces sufficient distance and let steel band 4 and section bar 1 temporarily separate, and steel band slider 32 needs to play again simultaneously and can seal up the effect again with section bar 1 at steel band 4 after integral type slider mechanism 3 slips away.

Specifically, the two sides of the screw rod sliding block 31 are symmetrically processed with sliding grooves 311, the profile 1 is integrally formed with a sliding rail 11 connected with the sliding grooves 311 in a sliding fit manner, and the matching surfaces of the sliding rail 11 and the sliding grooves 311 are both formed with a coating layer through surface treatment. The sliding grooves 311 slide along the sliding rails 11, the sliding grooves 311 are symmetrically arranged, so that the screw rod sliding blocks 31 can be suspended inside the section bars 1 and are only connected with the sliding grooves 311 through the sliding rails 11, the screw rod sliding blocks 31 cannot be in contact with the section bars 1 even if slightly inclined, the balance of the screw rod sliding blocks 31 is improved, and the possibility that the screw rod sliding blocks 31 can be subjected to larger friction force is reduced.

A first inclined plane and a second inclined plane are arranged in the sliding groove 311, the first inclined plane and the second inclined plane are intersected at the bottom of the sliding groove 311, the shape of the sliding rail 11 corresponds to that of the sliding groove 311, and the sliding rail 11 also has two inclined planes which are parallel to the first inclined plane and the second inclined plane respectively, so that the cross sections of the sliding rail 11 and the sliding groove 311 are triangular, the sliding rail 11 plays a guiding role for the screw rod sliding block 31, and also plays a role in supporting the screw rod sliding block 31. The coating layer is disposed on the two inclined planes of the slide rail 11 and the slide groove 311.

An arc surface 321 protruding outwards towards one side of the steel belt 4 is fixed on the steel belt slide block 32. The highest position of the arc-shaped surface 321 needs to satisfy the requirement that the space between the steel strip 4 and the profile 1 which are pushed open can allow the side wing 322 to pass through, and the lowest position is not higher than the top surface of the profile 1, so that after the side wing 322 slides away, the steel strip 4 can continuously adsorb to the profile 1 to be sealed. The arc-shaped surface 321 is fixed with a coating layer to increase hardness and reduce friction force, the surface of the coating layer is smooth, and the noise and the friction force are small when the steel strip 4 passes through.

The hard anodic oxide coating is preferably selected as the coating layer, the hardness of the coating layer is over HV400, the thickness of the coating layer can reach dozens or even hundreds of micrometers, the thickness is easy to control, the size precision is high, the coating layer is provided with micropores, various lubricants can be absorbed, the later maintenance is not needed, and the self-lubricating effect is achieved.

The flank 322 of the steel belt sliding block 32 penetrates out of the interval between the steel belt 4 and the section bar 1 and then is fixed with the load connecting seat 33, so that the load connecting seat 33 can move together with the steel belt sliding block 32, the steel belt sliding block 32 moves together with the screw rod sliding block 31, the screw rod 2 rotates to drive the screw rod sliding block 31 to move, and therefore the load can move.

Sealing baffles 331 are fixed on two sides of the load connecting seat 33, the inner sides of the sealing baffles 331 are fixedly connected with the side wings 322, the length of the sealing baffles 331 is not less than the length of the interval between the steel strip 4 and the section bar 1 (the length is the size along the axial direction of the screw rod 2), and a small gap is left between the bottom surfaces of the sealing baffles 331 and the top surface of the section bar 1, so that the section bar is prevented from interfering the movement of the load connecting seat 33. The interval between the steel strip 4 and the section bar 1 can be shielded by the sealing baffle 331, and the sealing performance of the linear module is improved.

An opening groove for the steel strip sliding block 32 to penetrate out is formed in the top plate of the section bar 1, and the width of the opening groove is smaller than that of the steel strip 4. Inlay the magnetic stripe 5 that is equipped with absorption steel band 4 on the 1 top surface of section bar, two magnetic stripes 5 distribute in the both sides of open slot, and the length of magnetic stripe 5 is isometric with the length of steel band 4 for steel band 4 can be fully adsorbed to magnetic stripe 5, only leaves the interval in the place that integral type slider mechanism 3 passes through, in case integral type slider mechanism 3 removes away and will adsorb. The bottom of arcwall face 321 is fixed with the magnetic path 6 that adsorbs steel band 4, and magnetic path 6 magnetizes arcwall face 321, and when integral type slider mechanism 3 removed, arcwall face 321 adsorbable steel band 4 made it just hug closely arcwall face 321 fast, formed the enclosure, and noise abatement reaches dustless standard, improves dustproof and waterproof grade.
