[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 1-5 , an embodiment provided by the utility model:

[0026] A linear guide rail slider gear connecting rod with a limiting mechanism, comprising:

[0027] The block includes a movable slider 1. The movable slider 1 is an existing product and is not a technical protection point of the present application, so no further description is made here.

[0028] The limiting mechanism includes a fixed block 2, which is arranged at both ends of the moving slider 1 and is used to limit the movement of the moving slider 1. A fixed tooth 21 is provided on the surface of the fixed block 2, so that the fixed tooth 21 can be embedded in the tooth-shaped groove 31 to fix the fixed block 2. A connecting groove 22 is provided on the surface of the fixed block 2 for inserting the plug-in rod 23. The surface of the fixed block 2 is plug-in connected with the plug-in rod 23 for connecting the fixed block 2 and the limiting block 24. The surface of the plug-in rod 23 is fixedly connected with the limiting block 24 for connecting the fixed block 2 to the surface of the rack guide 3. A slot 25 is provided on the surface of the limiting block 24 for inserting a fixing bolt 26. The interior of the slot 25 is threadedly sleeved with a fixing bolt 26 for connecting the fixed block 2 for fixing. After fixing, the limiting of the moving slider 1 is completed;

[0029] The moving mechanism includes a rack guide 3, which acts on the surface of the moving slider 1 to provide a guide for the movement of the moving slider 1. A toothed groove 31 is provided on the surface of the rack guide 3 for the movement of the rotating gear 32 and the engagement and fixation of the fixed tooth 21. The surface of the toothed groove 31 is movably connected with a rotating gear 32 so that the moving slider 1 can move on the surface of the rack guide 3. A connecting round rod 33 is penetrated and connected to the surface of the rotating gear 32 for connecting the moving slider 1 so that the rotating gear 32 can rotate.

[0030] Furthermore, the fixed teeth 21 are evenly arranged on the surface of the fixed block 2, and multiple groups of fixed teeth 21 can better form fixation. The width of the fixed teeth 21 is smaller than the width of the tooth-shaped groove 31, so that the fixed teeth 21 can be embedded in the tooth-shaped groove 31. The fixed block 2 is connected by the surface plug-in of the fixed teeth 21 and the tooth-shaped groove 31. When the fixed teeth 21 are plugged into the tooth-shaped groove 31, the fixed block 2 cannot move on the surface of the rack guide 3, thereby blocking the moving slider 1 and limiting the moving slider 1.

[0031] Furthermore, the plug-in rod 23 is cylindrical, the diameter of the connecting groove 22 is larger than the diameter of the plug-in rod 23, the limit block 24 is plugged and connected to the inside of the connecting groove 22 through the plug-in rod 23, the plug-in rod 23 is completely inserted into the connecting groove 22, the connection between the limit block 24 and the fixed block 2 is completed, and the rack guide rail 3 is clamped inside the fixed block 2 and the limit block 24, so that the limit can be carried out.

[0032] Furthermore, the diameter of the slot 25 is larger than the diameter of the fixing bolt 26, and the limit block 24 is threadedly connected through the fixing bolt 26 and the surface of the fixing block 2, and the fixing bolt 26 is inserted into the connecting groove 22 through the slot 25, and then tightened until the fixing bolt 26 is completely located inside the limit block 24 and the fixing block 2, completing the fixation of the connection between the fixing block 2 and the limit block 24. After screwing, the fixing block 2 and the limit block 24 can be freely moved to change the limit range of the moving slider 1.

[0033] Furthermore, the toothed groove 31 is evenly opened at the lower end of the rack guide 3, and the limit block 24 acts on the surface of the rack guide 3. The evenly opened toothed groove 31 enables the rotating gear 32 to move efficiently and stably, and ensures that the fixed tooth 21 can be fixed. The limit block 24 is placed on the surface of the rack guide 3, and the limit range can be processed as needed.

[0034] Furthermore, the width of the toothed groove 31 is greater than the width of the rotating gear 32 to ensure the movement of the rotating gear 32. The rotating gear 32 is in three groups, so that the moving slider 1 will be more stable and efficient when moving through the rotating gear 32 on the surface of the rack guide 3. The connecting round rod 33 passes through the rotating gear 32 and the inner surface of the moving slider 1 and is fixedly connected to connect the rotating gear 32 so that the rotating gear 32 can move, thereby driving the movement of the moving slider 1.

[0035] Furthermore, the movable slider 1 is movably connected to the lower end of the rack guide 3 through a rotating gear 32, and the evenly opened toothed grooves 31 provide a movable guide. The distribution of multiple sets of rotating gears 32 helps the movable slider 1 to move more efficiently, so that the movable slider 1 can move at the lower end of the rack guide 3.

[0036] Working principle: When using the movable slider 1, first pass the movable slider 1 through the front end of the rack guide rail 3 and move it to the middle area of ​​the rack guide rail 3. Then, it is necessary to limit the movable slider 1, and distribute the two sets of limit blocks 24 at both ends of the movable slider 1. After determining the limit range, align the connecting groove 22 of the fixed tooth 21 with the plug-in rod 23 and insert it. After determining that the fixed tooth 21 is fully in contact with the toothed groove 31, insert the fixing bolt 26 into the slot 25 and tighten the fixing bolt 26 until the fixing bolt 26 is completely immersed in the slot 25 to complete the limiting of the movable slider 1. When it is necessary to change the limiting range of the movable slider 1, the fixing bolt 26 is screwed in so that the fixing tooth 21 and the toothed groove 31 are no longer in contact. At this time, the fixed block 2 and the limit block 24 can be moved to change the limiting range. After determining the position, tighten the fixing bolt 26. During use, the movable slider 1 will move to the lower end of the rack guide rail 3 by rotating the rotating gear 32.

Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
