Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to a fixed rod connector. Background Technology

[0002] Liquid agronomic filling machines are pharmaceutical equipment specifically designed for filling liquid pesticides, fertilizers, plant growth regulators, and other agronomic products. These machines are commonly used in agricultural production processes to help achieve precise and automated filling of liquid agronomic products, thereby improving production efficiency and reducing waste.

[0003] Bottles loaded with pesticides in a liquid agronomic filling machine are conveyed through a production line. Limiting components are installed on the production line to prevent the bottles from tipping over during filling and conveying. The limiting components are installed on the production line by multiple fixing rods.

[0004] Multiple connectors are fixedly installed on the outside of the production line. Then, multiple fixing rods are installed on the multiple connectors to assemble the limiting component. The fixing rods are usually inserted into the connectors, and then the fixing rods are fixed by tightening the positioning bolts. This connection method is very cumbersome, requiring multiple bolts to be tightened one by one, resulting in low installation efficiency. Utility Model Content

[0005] The purpose of this utility model is to solve the problem that fixing the rod by tightening the positioning bolts is a very cumbersome connection method, which requires tightening multiple bolts one by one and has low installation efficiency. Therefore, a fixing rod connector is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A fixed rod connector includes a connecting seat and a mounting hole formed on the connecting seat, the mounting hole extending laterally through the connecting seat; a limiting rod slidably mounted on the connecting seat, wherein the limiting rod is arranged longitudinally, and the connecting seat is provided with a limiting part for driving the limiting rod into or away from the mounting hole.

[0008] In order to drive the limiting rod into the limiting groove to connect the rod body, preferably, the limiting part includes a sliding groove opened inside the connecting seat, a limiting ring is fixedly connected to the circumferential surface of the limiting rod, the limiting ring is slidably connected to the inner wall of the sliding groove, and a first spring is fixedly connected between the limiting ring and the inner wall of the sliding groove.

[0009] In order to limit the position of the limiting rod, preferably, a protrusion is fixedly connected to one end of the limiting rod extending out of the connecting seat, a first magnet is fixedly connected to the upper surface of the protrusion, a circular plate is fixedly connected to the top of the connecting seat, and a second magnet is fixedly connected to the bottom of the circular plate. The second magnet and the first magnet attract each other.

[0010] To further limit the position of the limiting rod, preferably, a limiting hole is provided on the limiting rod.

[0011] To facilitate the removal of the fixing block from the limiting hole, a groove is further provided at one end of the extending connecting seat of the limiting rod. A pressure plate is slidably installed on the inner wall of the groove. A third spring is fixedly connected between the bottom of the pressure plate and the inner wall of the groove. A connecting rod is fixedly connected to the bottom of the pressure plate. The connecting rod is slidably connected to the limiting rod. A roller is rotatably installed below the connecting rod, and the roller is located in the limiting hole.

[0012] For the installation of the connector, preferably, a fixing plate is fixedly connected to the connector, and the fixing plate has threaded holes.

[0013] Compared with the prior art, the present invention provides a fixed rod connector, which has the following advantages:

[0014] 1. This fixed rod connector allows the limiting rod to be pulled out of the mounting hole by the limiting part, then the rod body is inserted into the mounting hole, and then the limiting part is used to insert the limiting rod into the limiting groove, thereby making it easy to connect and install the rod body and improving the efficiency of installation and connection.

[0015] 2. This fixed rod connector, by setting a fixed block and a limiting groove, allows the fixed block to slide into the sliding groove and compress the second spring when the lower surface of the limiting rod contacts the inclined surface of the top of the fixed block during the insertion of the limiting rod into the limiting groove. When the limiting rod is fully inserted into the limiting groove, the second spring returns to its original position, allowing the fixed block to be inserted into the limiting hole, thus limiting the limiting rod and preventing it from easily moving out of the limiting groove, thereby improving the stability of the installation connection.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0023] Example:

[0024] Reference Figures 1-4This utility model provides a fixed rod connector, including a connecting seat 1, a fixing plate 5 fixedly connected to the connecting seat 1, and a threaded hole 6 on the fixing plate 5. The connecting seat 1 is fixed to the production line by bolts through the threaded hole 6 on the fixing plate 5. It also includes a mounting hole 201 opened on the connecting seat 1, and the mounting hole 201 laterally penetrates the connecting seat 1. The mounting hole 201 matches a rod 4 in the prior art. The rod 4 is a fixed rod, on which a limiting component for limiting the bottle is fixedly connected. The rod 4 is laterally inserted into the mounting hole 201. A limiting groove 202 is formed on the surface of the rod body 4; a limiting rod 203 is slidably installed on the connecting seat 1. The limiting rod 203 is arranged longitudinally to prevent the rod body 4 from sliding laterally. The limiting rod 203 is inserted into the limiting groove 202. The connecting seat 1 is provided with a limiting part that drives the limiting rod 203 to enter or move away from the limiting groove 202. That is, when the limiting rod 203 enters the mounting hole 201, the limiting rod 203 cooperates with the limiting groove 202 to lock the rod 4. When the limiting rod 203 disengages from the mounting hole 201, that is, moves away from the limiting groove 202, the rod 4 has the freedom to slide laterally.

[0025] During connection, the limiting rod 203 is pulled out of the mounting hole 201 by the limiting part, and then the rod body 4 is inserted into the mounting hole 201. The limiting part is then used to insert the limiting rod 203 into the limiting groove 202, so that the rod body 4 can be easily connected and installed, thus improving the efficiency of installation and connection.

[0026] The limiting part includes a groove 204 formed inside the connecting seat 1. A limiting ring 205 is fixedly connected to the circumferential surface of the limiting rod 203. The limiting ring 205 is used to limit the limiting rod 203 and prevent the limiting rod 203 from being pulled out from the top of the connecting seat 1. The limiting ring 205 is slidably connected to the inner wall of the groove 204. A first spring 206 is fixedly connected between the top of the limiting ring 205 and the inner wall of the groove 204. A protrusion 207 is fixedly connected to one end of the limiting rod 203 that extends out of the connecting seat 1. The protrusion 207 acts as a handle. A first magnet 208 is fixedly connected to the upper surface of the protrusion 207. A circular plate 209 is fixedly connected to the top of the connecting seat 1. A second magnet 210 is fixedly connected to the bottom of the circular plate 209. The second magnet 210 and the first magnet 208 attract each other. The attraction between the second magnet 210 and the first magnet 208 is greater than the elastic force of the first spring 206.

[0027] During connection, by pulling the protrusion 207 upward, the protrusion 207 drives the limiting rod 203 to slide upward. The limiting rod 203 drives the limiting ring 205 to slide upward along the slide groove 204 and compress the first spring 206, pulling the limiting rod 203 out of the mounting hole 201. Then, by continuously pulling the protrusion 207, the first magnet 208 and the second magnet 210 on the protrusion 207 come into contact and attract each other. At this time, the limiting rod 203 cannot slide downward automatically. Then, the rod body 4 is inserted into the mounting hole 201, and the protrusion 207 is pulled to move the first magnet 208 and the second magnet 210 away. The protrusion 207 is released, the first spring 206 returns to its original position, and the limiting ring 205 slides downward along the slide groove 204. The limiting ring 205 drives the limiting rod 203 to slide downward, and the limiting rod 203 is inserted into the limiting groove 202, completing the connection of the rod body 4.

[0028] The rod body 4 has a sliding groove 301 communicating with the limiting groove 202 inside. The sliding groove 301 is arranged horizontally. A fixing block 302 is slidably installed on the inner wall of the sliding groove 301. There are two fixing blocks 302 arranged symmetrically. The top of the fixing block 302 is provided with an inclined surface. A second spring 303 is fixedly connected between the fixing block 302 and the inner wall of the sliding groove 301. A limiting hole 304 is provided on the limiting rod 203. The fixing block 302 is inserted into the limiting hole 304. A groove 305 is provided at one end of the limiting rod 203 that extends out of the connecting seat 1. The groove 305 is recessed downward. A pressure plate 306 is slidably installed on the inner wall of the groove 305. In the initial state, the pressure plate 306 is flush with the upper end of the limiting rod 203. A third spring 307 is fixedly connected between the bottom of the pressure plate 306 and the inner wall of the groove 305. In the middle, a connecting rod 308 is fixedly connected to the bottom of the pressure plate 306. The connecting rod 308 is arranged longitudinally and is slidably connected to the limiting rod 203. A roller 309 is rotatably installed below the connecting rod 308. The roller 309 is located in the limiting hole 304. When the fixing block 302 is inserted into the limiting hole 304, the roller 309 contacts the inclined surface of the fixing block 302. The bottom of the fixing block 302 is chamfered, and the bottom edge of the inner wall of the limiting hole 304 is also chamfered. The lower surface of the limiting rod 203 is rounded. By inserting the fixing block 302 into the limiting hole 304, the limiting rod 203 is limited, preventing the first spring 206 from deforming when the liquid agronomic filling machine vibrates during operation, causing the limiting rod 203 to move out of the limiting groove 202 and the rod body 4 to detach.

[0029] During connection, as the limiting rod 203 is inserted into the limiting groove 202, the rounded corner of the lower surface of the limiting rod 203 contacts the inclined surface of the top of the fixing block 302. The fixing block 302 is then pressed and slides into the sliding groove 301, compressing the second spring 303. When the limiting rod 203 is fully inserted into the limiting groove 202, the second spring 303 returns to its original position, allowing the fixing block 302 to insert into the limiting hole 304, thus limiting the limiting rod 203 and preventing it from easily moving out of the limiting groove 202. This improves the stability of the installation connection. When disassembling the rod body 4, the limiting rod 203 needs to be pulled out of the limiting groove 202. Before this, the pressure plate 306 is pressed down. The pressure plate 306 slides downward along the groove 305 and compresses the third spring 307. Simultaneously, the pressure plate 306 drives the connecting rod 3... 08 moves downwards, and the connecting rod 308 drives the roller 309 to move synchronously. The roller 309 rolls on the inclined surface of the fixed block 302 and squeezes the fixed block 302, causing the fixed block 302 to slide into the sliding groove 301 and compress the second spring 303. Since the roller 309 is in the limiting hole 304, the fixed block 302 will not completely move out of the limiting hole 304. At this time, the bottom of the fixed block 302 is stuck at the bottom edge of the limiting hole 304. Then, the limiting rod 203 is pulled upwards, and the limiting hole 304 squeezes the fixed block 302, causing the fixed block 302 to slide further into the sliding groove 301 and compress the second spring 303. At this time, the fixed block 302 is completely moved out of the limiting hole 304, and the limiting rod 203 can be pulled out from the limiting groove 202 to complete the disassembly of the rod body 4.

[0030] In use, this fixed rod connector works by pulling the protrusion 207 upward, causing the limiting rod 203 to slide upward. The limiting rod 203 then causes the limiting ring 205 to slide upward along the slide groove 204 and compress the first spring 206, pulling the limiting rod 203 out of the mounting hole 201. Then, by continuously pulling the protrusion 207, the first magnet 208 and the second magnet 210 on the protrusion 207 come into contact and attract each other. At this point, the limiting rod 203 cannot slide downward automatically. Next, the rod body 4 is inserted into the mounting hole 201, and then the protrusion 207 is pulled to move the first magnet 208 and the second magnet 210 away. Releasing the protrusion 207 resets the first spring 206, causing the limiting ring 205 to slide downward along the slide groove 204. The limiting ring 205 then causes the limiting rod 203 to slide downward, inserting the limiting rod 203 into the limiting groove 202, thus completing the connection of the rod body 4.

[0031] During the process of inserting the limiting rod 203 into the limiting groove 202, after the rounded corner of the lower surface of the limiting rod 203 contacts the inclined surface of the top of the fixing block 302, the fixing block 302 is squeezed and slides into the sliding groove 301, compressing the second spring 303. When the limiting rod 203 is fully inserted into the limiting groove 202, the second spring 303 returns to its original position, so that the fixing block 302 is inserted into the limiting hole 304, limiting the limiting rod 203 and preventing the limiting rod 203 from easily moving out of the limiting groove 202, thus improving the stability of the installation connection.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
