Description

Technical Field

[0001] This utility model relates to the field of electric door technology, specifically to an electric door guide rail reinforcement and adjustment device. Background Technology

[0002] Electric gates, also known as "electric sliding gates" or "electric folding gates," are categorized by "electric" type into standard, electromechanical integrated, and intelligent integrated types. Electric gates, in general, refer to industrial doors, sliding gates, revolving doors, swing doors, roller shutters, and cantilever doors.

[0003] Application number CN202321276523.X discloses a guide rail mechanism for electric doors with adjustable length that is easy to install. This mechanism includes a threaded screw, a threaded cylinder, a limiting hole, a guide rod, a guide tube, a mounting hole, and bolts. The guide rail can be extended or retracted based on the connection between the guide rod and the guide tube. The threaded screw and the threaded cylinder work together to allow the threaded screw to rotate inside the cylinder while simultaneously inserting into the limiting hole. This combination of the limiting hole and the threaded screw effectively limits the guide rod's position. The method is simple and convenient to use, and the length can be easily adjusted according to usage requirements. However, this design has shortcomings. When the guide rod is fixed in position by the threaded screw and the guide tube, the threaded screw must be manually screwed into the threaded cylinder and precisely inserted into the limiting hole. This operation is cumbersome, consuming a lot of time and manpower, reducing installation efficiency. Furthermore, if the alignment of the threaded screw and the limiting hole is misaligned during installation, it can lead to installation failure, increasing the difficulty and probability of errors.

[0004] Therefore, we propose a reinforcement and adjustment device for electric door guide rails. Utility Model Content

[0005] The main purpose of this utility model is to provide an electric door guide rail reinforcement and adjustment device. Through the linkage structure design of knob, turntable, rotating shaft, gear and threaded rod, the operation process of adjusting and fixing the guide rail length is greatly simplified, which can effectively solve the problems in the background technology.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] An electric door guide rail reinforcement and adjustment device includes a guide tube and a guide rod. The guide tube has a first cavity, a second cavity and a third cavity arranged from left to right. One end of the guide rod is horizontally inserted into the third cavity. The first cavity is provided with a first gear, a second gear and a rotating shaft. The second cavity is provided with a horizontally arranged threaded rod, a top rod and a vertically arranged push plate. Sliding plates are fixedly connected to the inner walls on both sides of the third cavity.

[0008] The lower part of the conduit away from the third cavity has an embedded groove for installing fasteners. The fasteners are fastened to the lower part of the conduit from bottom to top. A horizontally arranged turntable is provided below the fasteners. A vertically arranged rotating shaft is fixedly connected to the center of the upper surface of the turntable. A knob is fixedly connected to the center of the lower surface of the turntable. The turntable is fixedly connected to the bottom end of the fasteners by a positioning bolt.

[0009] By adopting the above technical solution and through the linkage structure design of knob, turntable, shaft, gear and threaded rod, the operation process of adjusting and fixing the guide rail length is greatly simplified.

[0010] Specifically, the top end of the rotating shaft passes through the fastener, the inner wall of the bottom end of the first cavity, and is fixedly connected to the bottom end of the first gear at the center. The rotating shaft is rotatably connected to the guide tube and the fastener.

[0011] Specifically, the first gear and the second gear are arranged at a right angle, the first gear meshes with the second gear, and the second gear is fixedly sleeved on one end of the threaded rod.

[0012] Specifically, the end of the threaded rod away from the second gear is rotatably connected to the inner wall of the second cavity near the third cavity, and the other end of the threaded rod passes through the inner wall of the second cavity and is rotatably connected to the inner wall of the first cavity.

[0013] Specifically, the push plate is sleeved on the threaded rod, and both ends of the push plate are slidably connected to the inner walls of the second cavity. A top rod is vertically inserted into the side of the push plate near the third cavity.

[0014] Specifically, the end of the push rod away from the push plate passes through the inner wall of the second cavity and is vertically inserted into one end of the guide rod. Both sides of the guide rod are provided with sliding grooves that are adapted to the sliding plate.

[0015] The beneficial effects of this utility model are as follows: The electric door guide rail reinforcement and adjustment device described in this utility model greatly simplifies the operation process of adjusting and fixing the guide rail length through the linkage structure design of knob, turntable, rotating shaft, gear and threaded rod. Compared with the traditional method that requires manual screwing of the threaded rod into the threaded cylinder and precise insertion into the limiting hole, this device only requires turning the knob to realize the push and fixation of the guide rod by the top rod through mechanical transmission. There is no need for cumbersome alignment operation, which significantly reduces the installation difficulty, saves a lot of time and labor costs, and greatly improves the installation efficiency. The cooperation of the sliding plate and the sliding groove ensures the stability of the guide rod when sliding in the third cavity, effectively avoiding the shaking or deviation of the guide rod. At the same time, the fixing method of the top rod vertically inserting into the guide rod provides a more stable connection effect compared with the fixing of the threaded rod and the limiting hole, reduces the risk of installation failure due to poor connection, improves the stability and reliability of the overall structure of the guide rail, and extends the service life of the electric door guide rail.

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] As one embodiment of this utility model, such as Figures 1-3 As shown, the electric door guide rail reinforcement and adjustment device of this utility model includes a guide tube 1 and a guide rod 2. The guide tube 1 has a first cavity 4, a second cavity 5 and a third cavity 6 arranged from left to right. One end of the guide rod 2 is horizontally inserted into the third cavity 6. The first cavity 4 is provided with a first gear 8, a second gear 9 and a rotating shaft 10. The second cavity 5 is provided with a horizontally arranged threaded rod 16, a top rod 15 and a vertically arranged push plate 14. Sliding plates 7 are fixedly connected to the inner walls on both sides of the third cavity 6.

[0023] The lower part of the conduit 1 away from the third cavity 6 is provided with an embedding groove for installing fastener 11. The fastener 11 is fastened to the lower part of one end of the conduit 1 from bottom to top. A horizontally arranged turntable 12 is provided below the fastener 11. A vertically arranged rotating shaft 10 is fixedly connected to the center of the upper end face of the turntable 12. A knob 17 is fixedly connected to the center of the lower end face of the turntable 12. The turntable 12 is fixedly connected to the bottom end of the fastener 11 by a positioning bolt 13.

[0024] In use, when the length of the guide tube 1 needs to be adjusted, the operator turns the knob 17, which drives the turntable 12 to rotate. The turntable 12 rotates the first gear 8 via the shaft 10. Since the first gear 8 and the second gear 9 are arranged at right angles and mesh with each other, the rotation of the first gear 8 will drive the second gear 9 to rotate. The second gear 9 is fixedly sleeved on one end of the threaded rod 16, which in turn causes the threaded rod 16 to rotate. When the threaded rod 16 rotates, the push plate 14 moves horizontally along the threaded rod 16. As the push plate 14 moves towards the third cavity 6, the push rod 15 on one side of the push plate 14 can push the guide rod 2 out of the third cavity 6 until the guide rod 2 is pushed to the designated position. After determining its length, the top of the positioning bolt 13 is threaded through the turntable 12 and connected to the fastener 11, thereby positioning the guide rod 2.

[0025] The present invention also includes that the top end of the rotating shaft 10 passes through the fastener 11 and the inner wall of the bottom end of the first cavity 4 in sequence and is fixedly connected to the bottom end of the first gear 8 at the center. The rotating shaft 10 is rotatably connected to the guide tube 1 and the fastener 11.

[0026] The present invention also includes that the first gear 8 and the second gear 9 are arranged at right angles, the first gear 8 and the second gear 9 mesh, and the second gear 9 is fixedly sleeved on one end of the threaded rod 16.

[0027] The present invention further includes that the end of the threaded rod 16 away from the second gear 9 is rotatably connected to the inner wall of the second cavity 5 near the third cavity 6, and the other end of the threaded rod 16 passes through the inner wall of the second cavity 5 and is rotatably connected to the inner wall of the first cavity 4.

[0028] The present invention also includes that the push plate 14 is sleeved on the threaded rod 16, both ends of the push plate 14 are slidably connected to the inner walls of both sides of the second cavity 5, and a top rod 15 is vertically inserted into the side of the push plate 14 near the third cavity 6.

[0029] The present invention also includes that the end of the push rod 15 away from the push plate 14 passes through the inner wall of the second cavity 5 and is vertically inserted into one end of the guide rod 2, and both sides of the guide rod 2 are provided with sliding grooves 3 that are adapted to the sliding plate 7.

[0030] When using this utility model, firstly, one end of the guide rod 2 is horizontally inserted into the third cavity 6 of the guide tube 1. The sliding grooves 3 on both sides of the guide rod 2 cooperate with the sliding pieces 7 on both sides of the inner wall of the third cavity 6, so that the guide rod 2 can slide smoothly in the third cavity 6, realizing the basic operation of length adjustment.

[0031] When the length of the guide tube 1 needs to be adjusted, the operator turns the knob 17, which drives the turntable 12 to rotate. The turntable 12 rotates the first gear 8 through the rotating shaft 10. Since the first gear 8 and the second gear 9 are arranged at right angles and mesh with each other, the rotation of the first gear 8 will drive the second gear 9 to rotate. The second gear 9 is fixedly sleeved on one end of the threaded rod 16, which in turn causes the threaded rod 16 to rotate. When the threaded rod 16 rotates, the push plate 14 moves horizontally along the threaded rod 16. As the push plate 14 moves towards the third cavity 6, the push rod 15 on one side of the push plate 14 can push the guide rod 2 out of the third cavity 6 until the guide rod 2 is pushed to the designated position. After determining its length, the top of the positioning bolt 13 is threaded through the turntable 12 and connected to the fastener 11, thereby positioning the guide rod 2.
