Description

Technical Field

[0001] This invention relates to the field of mechanical technology, and more specifically, to a linear guide. Background Technology

[0002] The main components of a linear guide rail include a guide rail body and a slider slidably connected to the guide rail body. Parts mounted on the slider can reciprocate along with the slider on the guide rail body, but can only perform linear reciprocating movements and cannot perform other movements, including rotation. Accordingly, this invention proposes a linear guide rail. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a linear guide rail.

[0004] To solve the above-mentioned technical problems, the present invention achieves its objective as follows: A linear guide rail according to the present invention includes a guide rail base extending horizontally left and right. The guide rail base has two side frames arranged symmetrically left and right. A main guide rod and a secondary guide rod extending horizontally left and right are provided between the side frames. A slider is slidably connected to the main guide rod, and a sliding sleeve is slidably connected to the secondary guide rod. The sliding sleeve and the slider are connected by a bracket. The secondary guide rod is composed of two guide rod units arranged coaxially, with a movable gap between the two guide rod units. Below the movable gap is a gear mounting hole opened on the guide rail base. A driven gear is rotatably connected to the guide rail base in the gear mounting hole, and a driving gear meshes with the driven gear. The axis of the driven gear also extends horizontally left and right. The bottom of the slider has a fixed missing gear adapted to the driven gear. When the sliding sleeve is within the movable gap, the fixed missing gear meshes with the driven gear.

[0005] The width of the movable gap is greater than the height of the sliding sleeve, and the width of the driven gear is not less than the width of the movable gap; the cross-section of the main rod is circular.

[0006] The present invention is further configured such that: the number of the main guide rod is one, the number of the auxiliary guide rods is two, and the auxiliary guide rods are respectively disposed on the front and rear sides of the main guide rod.

[0007] The present invention is further configured such that: the end of any of the guide rod units facing the other guide rod unit has a guide portion.

[0008] The present invention is further configured such that the top of the slider is provided with a threaded mounting hole.

[0009] The present invention is further configured such that the width of the driven gear is greater than the width of the clearance.

[0010] The present invention is further configured such that a power source for controlling the rotation of the drive gear is connected to the drive gear.

[0011] In summary, the present invention has the following beneficial effects: the linear guide rail involved in the present invention can achieve the rotation of the slider by inputting a power source and transmitting through gears when the slider moves to a set position, thereby achieving the steering effect of the components installed on it; if no power source input is applied, it can still be used as a conventional linear guide rail. The structure is special and novel, the overall function is complete, and the practicality is strong. Attached Figure Description

[0016] To enable those skilled in the art to better understand the technical solutions of the present invention, preferred embodiments of the present invention are described below in conjunction with specific examples. However, it should be understood that these descriptions are merely for further illustrating the features and advantages of the present invention, and not for limiting the scope of the patent claims of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0017] The present invention will be further described below with reference to the accompanying drawings and preferred embodiments.

[0018] Example 1

[0019] See Figures 1 to 4As shown, the linear guide rail involved in this embodiment includes a guide rail base 1 extending horizontally left and right. Two side frames 2 are symmetrically arranged left and right on the guide rail base 1. A main guide rod 3 and a secondary guide rod 4 extending horizontally left and right are arranged between the side frames 2. A slider 5 is slidably connected to the main guide rod 3, and a sliding sleeve 6 is slidably connected to the secondary guide rod 4. The sliding sleeve 6 and the slider 5 are connected by a bracket 7. The secondary guide rod 4 is composed of two guide rod units 41 arranged coaxially. A movable gap 42 is left between the two guide rod units 41. Below the movable gap 42, there is a [missing information - likely a design feature] formed on the [missing information - likely a design feature]. The guide rail seat has a gear mounting hole 8, within which a driven gear 9 is rotatably connected to the guide rail seat. A driving gear 10 meshes with the driven gear 9. The axis of the driven gear 9 extends horizontally to the left and right. The bottom of the slider 5 has a fixed missing gear 11 that matches the driven gear. When the sliding sleeve 6 is within the movable gap, the fixed missing gear 11 meshes with the driven gear 9. The width of the movable gap 42 is greater than the height of the sliding sleeve 6, and the width of the driven gear 9 is greater than the width of the movable gap 42. The cross-section of the main guide rod 3 is circular. The driven gear 9, driving gear 10, and fixed missing gear 11 are all spur gears.

[0020] Furthermore, there is one main guide rod 3 and two auxiliary guide rods 4, which are respectively located on the front and rear sides of the main guide rod 3.

[0021] Furthermore, each of the guide rod units 41 has a guide portion 43 at the end facing the other guide rod unit 41.

[0022] Furthermore, the top of the slider 5 is provided with a threaded mounting hole 12.

[0023] Furthermore, the drive gear 10 is connected to a power source (not shown in the figure) that controls its rotation.

[0024] In this embodiment, the slider 5 can reciprocate on the main guide rod 3. When the slider 5 moves above the movable gap 42, the sliding sleeve 6 disengages from the guide rod unit 41 on the secondary guide rod 4 and is located within the movable gap 42. However, at this time, because the fixed missing gear 11 is engaged with the driven gear 9, even if the cross-section of the main guide rod 3 is circular, the slider 5 will not deflect, swing, or rotate. If it is necessary to add a compound motion of the slider 5 in another direction at this position, such as rotation around an axis, rotational power can be applied to the driving gear 10. Through the transmission of the driven gear 9 and the fixed missing gear 11, the slider 5 can be driven to rotate relative to the main guide rod 3.

[0025] Among them, by setting auxiliary guide rods 4 on both sides of the main guide rod 3, the forces on both sides are balanced during the sliding of the slider 5; and the auxiliary guide rods 4 help to limit the back-and-forth swing of the slider 5 (when the sliding sleeve 6 is disengaged from the auxiliary guide rod 4, it can be used as a swing limiter during the swing).

[0026] The addition of guide section 43 enables slider 5 located in movable gap 42 to quickly match guide rod unit 41 and play a sliding guiding role.

[0027] The linear guide rail involved in this invention can rotate the slider by inputting a power source and transmitting it through gears when the slider moves to a set position, thereby achieving the steering effect of the components installed on it; if no power source input is applied, it can still be used as a conventional linear guide rail. It has a special and novel structure, complete overall functions, and strong practicality.
