[0002] In real life, the matching of gears and racks is a common and important mechanical matching structure. Because it is common and critical, the safety of gears and racks needs to be taken seriously. One of the common potential problems is that the gear may detach from the rack, which will not only interrupt the task being performed by the sliding of the gear, but may also cause safety problems.
[0003] In the prior art, the friction between the gear and the rack is usually increased to press the two together as tightly as possible. However, this method is relatively rough and has a poor effect. Utility Model Content

[0015] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0016] One of the core concepts of the utility model is that gears are arranged in the space formed in the middle of the relatively connected gear protection shells, so that when the gears rotate in the ordinary way (slide on the gear guide rail), they will not deviate in the direction perpendicular to the plane where the gears are located; and the relatively connected gear protection shells are fixed on the fixed shell, and the space formed between the short side of the fixed shell and the pulley can just allow the gear protection shells to maintain their position at a certain distance on the gear guide rail, so that the gears will not deviate from the gear guide rail in a direction parallel to the plane where the gears are located and perpendicular to the gear guide rail.
[0017] See Figures 1 to 4 A safety system 1 for preventing gear derailment comprises: a gear guide rail 2, a gear 3, a fixed housing 4, and a pair of gear protection housings 5 arranged in relative connection; the fixed housing 4 comprises a first L-shaped plate 41 and a pulley 42 arranged on the inner side of the long side of the first L-shaped plate away from the short side; the pulley 42 is tightly fitted on one side of the smooth surface 21 of the gear guide rail, and a gear is arranged on the rack side 22 on the other side of the gear guide rail; the gear 3 is arranged in the middle recess of the gear protection housing 5, and is fixedly connected to the short side of the L plate of the fixed housing 4.
[0018] Reference Figure 1 , showing a schematic three-dimensional diagram of the safety system provided in this embodiment.
[0019] In the figure, the sliding part formed by the gear 3 and the gear protection housing 5 slides on the gear guide rail 2 and is restricted by the fixed housing 4 so that the gear 3 will not separate from the rack when sliding.
[0020] Reference Figures 2 to 4 , Figure 2The enlarged schematic diagram of a part of the safety system provided by the present embodiment is shown. The fixed housing 4 includes a first L-shaped plate 41 and a pulley 42 arranged on the inner side of the long side of the first L-shaped plate 41 away from the short side. The pulley 42 is tightly fitted on the smooth surface 21 of the gear guide 2. The space formed between the pulley and the short side of the fixed housing 4 is just enough to allow the gear protection housing 5 to maintain a certain distance on the gear guide 2, and the gear 3 will not derail from the rack 22 when sliding.
[0021] The gear protection housing 5 is a second L-shaped plate. A pair of gear protection housings are arranged opposite to each other, and the gear 3 is arranged in a space formed by the opposite arrangement and is tightly fitted with the rack side 22 of the gear guide rail 2 .
[0022] In this embodiment, the number of pulleys is two. And the fixed housing and the gear protection housing are fixedly connected by bolts. In this embodiment, the fixed housing and the gear protection housing are fixedly connected by four bolts. Similarly, a pair of oppositely arranged gear protection housings are also fixedly connected by bolts, wherein the long sides of the gear protection housings are fixedly connected. In this embodiment, the gear protection housings are fixedly connected by four bolts.
[0023] The fixed housing is fixed to the gear protection housing, and the two gear protection housings are relatively fixed, so that the gear arranged between the two gear protection housings will not be separated from the rack when sliding.
[0024] See Figure 3 to Figure 4 When the gear 3 slides on the rack side 22 of the gear guide 2, due to the limiting effect of the above-mentioned fixed housing 4 and the gear protection housing 5, it will not deviate in the direction perpendicular to the plane where the gear is located, and the gear will not deviate from the gear guide in the direction parallel to the plane where the gear is located and perpendicular to the gear guide.
[0025] The utility model of the present application provides a safety system for preventing gears from derailing, comprising a gear guide rail, a gear, a fixed housing, and a pair of gear protection housings arranged in relative connection; the fixed housing comprises a first L-shaped plate and a pulley arranged on the inner side of the long side of the first L-shaped plate away from the short side; the pulley is tightly fitted on one side of the smooth surface of the gear guide rail, and a gear is arranged on the rack side on the other side of the gear guide rail; the gear is arranged in a recessed position in the middle of the gear protection housing, and is fixedly connected to the short side of the first L-shaped plate of the fixed housing. According to the utility model, when the gear slides on the gear guide rail, the gear can be prevented from being separated from the gear guide rail due to the limiting effect of the fixed housing and the gear protection housing.
