Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery connection technology, specifically to an agricultural machinery connector. Background Technology

[0002] Agricultural machinery connectors are an important structural element in agricultural machinery design. They connect the housing structure to the machinery, improving overall rigidity and stability, preventing loosening and detachment of components during operation, and ensuring reliability and safety. Connectors also facilitate easy disassembly and repair of the housing and machinery, greatly simplifying maintenance. However, traditional agricultural machinery connectors use simple pin connections, which makes turning and disassembly inconvenient and prone to damage over time. Furthermore, the need for manual lifting during installation poses a safety hazard. Utility Model Content

[0003] Therefore, the purpose of this utility model is to provide an agricultural machinery connector that can be quickly and conveniently snapped together, thereby saving users a lot of physical effort when connecting and reducing safety hazards during installation.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an agricultural machinery connector, comprising a first connecting block, a first connecting member, and a second connecting member. The first connecting member is disposed on the inner side of the first connecting block, and two sets of fixing plates are fixed on the front surface of the first connecting member. A sliding cylinder is fixed at one end of the fixing plate away from the horizontal central axis of the first connecting member, and a sliding plate slides inside the sliding cylinder. A limiting block is fixed at one end of the sliding plate close to the horizontal central axis of the first connecting member, and a first pushing surface is provided on one side of the limiting block. A second pushing surface is symmetrically disposed on one side of the second connecting member.

[0005] By adopting the above technical solution, the first connecting member forms an integrated structure with the slide cylinder through the fixing plate. The slide cylinder is used to provide sliding space for the slide plate, and the slide plate is used to drive the limiting block to slide. The limiting block is fitted with the second pushing surface on the second connecting member through the first pushing surface, and the second connecting member pushes the limiting block through the second pushing surface.

[0006] Furthermore, the first connecting block and the first connecting piece are both inserted and engaged with the two sets of first connecting rods. Each set of first connecting rods has a hole-like structure on one side and is inserted into the fixing rod. Both sides of the fixing rod are fixed with spring clips and are engaged with the first connecting rods.

[0007] By adopting the above technical solution, the first connecting block and the first connecting member are both inserted and engaged with the two sets of first connecting rods. The hole-like structure opened on one side of the two sets of first connecting rods and the insertion design of the fixing rod provide additional support and fixing points for the first connecting rod, thereby enhancing the stability and tensile strength of the connecting member.

[0008] Furthermore, a pull rod is fixed to one end of the slide plate away from the horizontal central axis of the first connector, and slides and engages with the slide cylinder. A strong spring is fixed to the top inner side of the slide cylinder, and the other end of the strong spring is pressed against the slide plate.

[0009] By adopting the above technical solution, a pull rod is fixed at the end of the skateboard away from the horizontal central axis of the first connector, so that the operator can easily control the sliding of the skateboard in the slide tube by pulling the pull rod. A strong spring is fixed at the top of the inner side of the slide tube, and the other end of the strong spring is pressed against the skateboard. The design of the strong spring provides continuous elastic support for the skateboard.

[0010] Furthermore, a second connecting block is provided at one end of the second connecting member, and a rotating rod is rotatably provided at the middle of the second connecting block and the second connecting member.

[0011] By adopting the above technical solution, a second connecting block is provided at one end of the second connector, which enables the second connector to be easily connected to external equipment or components, expanding the application range and applicability of the connector. A rotating rod is rotatably provided in the middle of the second connecting block and the second connector. The rotation design allows the second connector to rotate within a certain range, thereby adapting to the connection requirements of different angles or positions.

[0012] Furthermore, both the first and second push surfaces are inclined structures, and the first and second push surfaces abut and fit together.

[0013] By adopting the above technical solution, both the first and second push surfaces are designed as inclined structures. When the second connector approaches the first connector, the second push surface can slide smoothly along the first push surface, thereby realizing the automatic alignment and guidance of the connector, which greatly improves the convenience and accuracy of the connection. The first and second push surfaces abut and fit together, ensuring the tight fit of the connector during the connection process and enhancing the stability and reliability of the connection.

[0014] Furthermore, four sets of locking blocks are fixed in a circular array on the outer side of the slide plate, and they engage and limit the movement of the slide cylinder.

[0015] By adopting the above technical solution, four sets of locking blocks are fixed in a circular array on the outer side of the skateboard. This design increases the contact points and locking points between the skateboard and the slide tube, making the skateboard slide more stably in the slide tube.

[0016] In summary, the present invention has the following main advantages:

[0017] 1. This utility model sets up a limiting block, a first pushing surface, a second connecting member, and a second pushing surface. The second connecting member is pushed so that the second connecting member pushes against the first pushing surface on one side of the limiting block through the second pushing surface. This allows the limiting block to drive the slide plate to slide inside the slide tube through the pushing force. When the second connecting member moves to the middle of the inner side of the fixed plate, the strong spring will release the slide plate through the elastic force generated during compression. This allows the slide plate to drive the limiting block to insert and engage with the hole-like structure in the middle of the second connecting member.

[0018] 2. This utility model, by setting a fixing rod and a spring clip, when the first connecting rod is used to insert and limit the first connecting block and the first connecting piece, inserts the fixing rod into the hole-like structure on one side of the first connecting rod, and at the same time uses the spring clip to lock the first connecting rod, thereby limiting the first connecting rod and effectively preventing the first connecting rod from falling off when limiting the first connecting block and the first connecting piece.

Detailed Implementation

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0025] In this embodiment:

[0026] A type of agricultural machinery connector, such as Figures 1-4As shown, it includes a first connecting block 1, a first connecting member 5, and a second connecting member 13. The first connecting member 5 is provided on the inner side of the first connecting block 1, and two sets of fixing plates 6 are fixed on the front surface of the first connecting member 5. A slide cylinder 7 is fixed at one end of the fixing plate 6 away from the horizontal central axis of the first connecting member 5, and a slide plate 8 slides inside the slide cylinder 7. A limit block 9 is fixed at one end of the slide plate 8 close to the horizontal central axis of the first connecting member 5, and a first push surface 10 is provided on one side of the limit block 9. A second push surface 14 is symmetrically provided on one side of the second connecting member 13.

[0027] The two sets of fixing plates 6 fixed to the front surface of the first connector 5 enhance the stability of the connection of the slide cylinder 7. The slide cylinder 7 fixed at the end of the fixing plate 6 away from the horizontal central axis of the first connector 5, and the sliding plate 8 inside the slide cylinder 7, constitute a flexible sliding mechanism, which allows the limiting block 9 to slide inside the slide cylinder 7 through the sliding plate 8 when needed, thereby accurately positioning and engaging the second connector 13. The first push surface 10 opened on one side of the limiting block 9 and the second push surface 14 symmetrically arranged on one side of the second connector 13 cooperate with each other, so that when the second connector 13 is inserted, the second push surface 14 can apply a pushing force to the first push surface 10, thereby driving the limiting block 9 and the sliding plate 8 to slide inside the slide cylinder 7.

[0028] See Figure 1 , Figure 2 and Figure 4 The first connecting block 1 and the first connecting piece 5 are both inserted and engaged with the two sets of first connecting rods 2. The two sets of first connecting rods 2 have a hole-like structure on one side and are inserted into the fixing rod 3. The fixing rod 3 has spring clips 4 fixed on both sides and engaged with the first connecting rod 2.

[0029] The two sets of first connecting rods 2 are designed to be inserted into the first connecting block 1 and the first connecting piece 5, making the connection between the first connecting block 1 and the first connecting piece 5 more stable and reliable. It also facilitates assembly and disassembly, improving the maintenance efficiency of agricultural machinery. Spring clips 4 are fixed on both sides of the fixing rod 3 and engage with the first connecting rod 2. The engaging design effectively prevents the fixing rod 3 from falling off during the insertion process or during use, ensuring the long-term stable operation of the connecting piece.

[0030] See Figure 1 , Figure 2 and Figure 3 A pull rod 11 is fixed at one end of the slide plate 8 away from the horizontal central axis of the first connecting piece 5, and slides and engages with the slide cylinder 7. A strong spring 12 is fixed at the top inner side of the slide cylinder 7, and the other end of the strong spring 12 is pressed against the slide plate 8.

[0031] Among them, the end of the slide plate 8 away from the horizontal central axis of the first connector 5 is fixed with a pull rod 11, which realizes precise control of the position of the limit block 9, and improves the flexibility and convenience of the connector. The top of the inner side of the slide cylinder 7 is fixed with a strong spring 12, and the other end of the strong spring 12 is pressed against the slide plate 8, so that the slide plate 8 can automatically reset when it is not subjected to external force, and maintain the stability of the connector.

[0032] See Figure 1 and Figure 2 A second connecting block 15 is provided at one end of the second connecting member 13, and a rotating rod 16 is rotatably provided at the middle of the second connecting block 15 and the second connecting member 13.

[0033] The connection between the second connecting block 15 and the second connecting member 13 provides additional support and stability for the connecting member, enhancing its overall stability and tensile strength. The stability and durability of the rotating rod 16 ensure the stability and reliability of the connecting member during long-term use, reducing agricultural machinery malfunctions or safety issues caused by loosening or damage to the connecting member.

[0034] See Figure 1 , Figure 2 and Figure 3 Both the first push surface 10 and the second push surface 14 are inclined structures, and the first push surface 10 and the second push surface 14 abut against each other and are adapted to each other.

[0035] The inclined structure design reduces friction during the connection process, making the connection smoother and reducing wear and damage to the connectors. The mating fit allows the connectors to support each other when subjected to external forces, jointly resisting the influence of external forces and maintaining the stability of the connection.

[0036] See Figure 3 Four sets of locking blocks are fixed in a circular array on the outer side of the slide plate 8, and they engage with the slide cylinder 7 to limit their movement.

[0037] Among them, four sets of locking blocks are fixed in a circular array on the outer side of the slide plate 8, which effectively prevents the slide plate 8 from tilting or shaking during the sliding process, and improves the accuracy and reliability of the connecting parts.

[0038] The implementation principle of this embodiment is as follows: First, the first connecting block 1 and the second connecting block 15 are installed in designated positions. The first connecting block 1 is fixedly connected to the external agricultural machinery by bolts, and the second connecting block 15 is fixedly connected to the external box and its other equipment by bolts. Then, the first connecting block 1 and the first connecting piece 5 are limited and inserted through the first connecting rod 2, and the fixing rod 3 is used to limit the insertion of the hole-like structure on one side of the first connecting rod 2. When the fixing rod 3 inserts into the first connecting rod 2, the spring clip 4 will form a locking structure with the first connecting rod 2 to prevent the fixing rod 3 from falling off when limiting the first connecting rod 2.

[0039] Then, the second connecting piece 13, which is rotatably connected to the second connecting block 15 by the rotating rod 16, is pushed against the first pushing surface 10 on the limiting block 9 by the second pushing surface 14. The second connecting piece 13 can push the limiting block 9 to both sides by the second pushing surface 14, so that the limiting block 9 slides inside the slide cylinder 7 by the slide plate 8. While the slide plate 8 is sliding, it will compress the strong spring 12. Then, when the second connecting piece 13 enters the inner side of the fixed plate 6, the limiting block 9 will be inserted and engaged with the hole structure in the middle of the second connecting piece 13 by the elastic potential energy of the slide plate 8 by the strong spring 12, so that the second connecting piece 13 is stably installed on the inner side of the fixed plate 6, and the second connecting block 15 can be connected to the first connecting block 1 by the second connecting piece 13 and the first connecting piece 5.

[0040] Finally, when it is necessary to disassemble the second connector 13, simply pull the lever 11 to release the locking block 9 from the second connector 13, thereby allowing the second connector 13 to slide out from the inside of the fixing plate 6.
