Description

Technical Field

[0001] This utility model relates to the field of printer technology, and more specifically, to a mechanical assembly connection structure with multiple types of constraints. Background Technology

[0002] In the field of mechanical design and assembly, the reliability, convenience, and safety of connection structures are crucial considerations. Traditional mechanical connection methods, such as bolt connections and pin connections, while widely used, have certain limitations. For example, bolt connections are prone to loosening under vibration, requiring additional anti-loosening measures (such as return spring washers and thread-locking agents), and installation and disassembly often require specific tools and a large operating space, resulting in low efficiency. Although pin connections can withstand shear forces, they typically lack effective axial restraint, requiring the addition of snap rings or cotter pins. These additional parts not only increase assembly steps but also pose a risk of loss or failure.

[0003] In the existing technology, some quick-connect or snap-fit ​​connection structures often have a single type of constraint. They either rely on the elasticity of plastic snaps, which have limited strength and durability, or they only provide unidirectional constraint, which may accidentally disengage under complex forces, resulting in insufficient safety. Utility Model Content

[0004] This utility model addresses the technical problems existing in the prior art by providing a mechanical assembly connection structure with multiple types of constraints. It solves the problem that some quick-connect or snap-fit ​​connection structures in the prior art often have only one type of constraint, either relying on the elasticity of plastic snaps, which have limited strength and durability, or only providing unidirectional constraints, which may accidentally disengage under complex forces, resulting in insufficient safety.

[0005] To achieve the above objectives, this utility model provides a mechanical assembly connection structure with multiple types of constraints, including a mounting plate and a connector. A mounting block is fixedly connected to the mounting plate, and a connector head is provided on the connector head, which includes a connecting block and a conical head. The connecting block is fixedly mounted on the connector head, and the conical head is fixed to the connecting block. A connecting groove and a conical groove are formed on the mounting block, and the conical head is disposed in the conical groove. The connecting block passes through the connecting groove. A constraint assembly is provided on the mounting block, which includes a first constraint member and a second constraint member, which constrain the connecting block and the conical head mounted on the mounting block.

[0006] Preferably, the first constraint member includes a first rectangular block fixedly connected to the side wall of the mounting block. The first rectangular block includes a first mounting cavity. A sliding plate is slidably connected to the inner wall of the first mounting cavity. An insertion rod is fixedly connected to the sliding plate. The mounting block has a through-hole that communicates with the first mounting cavity and the connecting groove. An insertion port is provided on the connecting block. The end of the insertion rod facing away from the sliding plate passes through the through-hole and extends into the insertion port.

[0007] Preferably, a connecting rod is fixedly connected to the side of the slide away from the insertion rod. The connecting rod passes through the side wall of the first rectangular block and is fixedly connected to a rectangular plate. A semi-circular pull ring is fixedly connected to the rectangular plate. Two return springs are symmetrically fixedly connected to the slide. The end of each return spring away from the slide is fixedly connected to the inner wall of the first mounting cavity.

[0008] Preferably, the second constraint component includes a second rectangular block fixedly connected to the upper surface of the first rectangular block. The second rectangular block has a second mounting cavity, which is connected to the first mounting cavity. The upper surface of the second rectangular block has a circular opening, in which a rotating plate is rotatably mounted. A screw is fixedly connected to the rotating plate, and a strip nut is threaded onto the screw. The insertion rod has a circular hole, and the lower end of the strip nut passes through the circular hole.

[0009] Preferably, the second rectangular block has a groove, and the strip nut is symmetrically fixed with sliding rods, with the opposite ends of the two sliding rods slidably connected to the inner wall of the second mounting cavity.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: By organically combining the conical surface positioning constraint, the spring pin lateral constraint, and the helical locking vertical constraint, the cooperation between the conical head and the conical groove achieves initial automatic alignment and axial load bearing. The insertion rod driven by the return spring provides the primary and rapid lateral locking. The helical driven bar nut serves as the final safety guarantee, locking the insertion rod and preventing its accidental retraction. This "three-in-one" constraint mechanism constitutes multiple insurances, greatly improving the reliability and anti-loosening ability of the connection structure under harsh working conditions such as vibration and impact.

Detailed Implementation

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Please see Figures 1-2This embodiment provides a mechanical assembly connection structure with multiple types of constraints, including a mounting plate 1 and a connector 3. A mounting block 2 is fixedly connected to the mounting plate 1. A connector head 301 is provided on the connector 3, comprising a connecting block 3011 and a conical head 3012. The connecting block 3011 is fixedly mounted on the connector 3, and the conical head 3012 is fixed to the connecting block 3011. A connecting groove 201 and a conical groove 202 are provided on the mounting block 2. The conical head 3012 is disposed in the conical groove 202, and the connecting block 3011 passes through the connecting groove 201. A constraint assembly 4 is provided on the mounting block 2, comprising a first constraint member 401 and a second constraint member 402. The first constraint member 401 and the second constraint member 402 constrain the connecting block 3011 and the conical head 3012 mounted on the mounting block 2. The first constraint member 401 includes a first rectangular block 4011 fixedly connected to the side wall of the mounting block 2. Rectangular block 4011 includes a first mounting cavity, on the inner wall of which a sliding plate 4012 is slidably connected. An insertion rod 4013 is fixedly connected to the sliding plate 4012. Mounting block 2 has a through-hole that communicates with the first mounting cavity and the connecting groove 201. Connecting block 3011 has an insertion port, and one end of the insertion rod 4013, facing away from the sliding plate 4012, passes through the through-hole and extends into the insertion port. Second constraint member 402 includes components fixedly connected to the first rectangular block 4011. The upper surface has a second rectangular block 4021, which has a second mounting cavity. The second mounting cavity is connected to the first mounting cavity. The upper surface of the second rectangular block 4021 has a round opening, in which a rotating plate 4022 is rotatably installed. A screw 4023 is fixedly connected to the rotating plate 4022. A strip nut 4024 is threadedly connected to the screw 4023. A round hole is opened on the insertion rod 4013, and the lower end of the strip nut 4024 passes through the round hole.

[0015] In summary, the improvement of this embodiment lies in: By organically combining the conical surface positioning constraint, the spring pin lateral constraint, and the helical locking vertical constraint, the cooperation between the conical head 3012 and the conical groove 201 achieves initial automatic alignment and axial load bearing; the helical driven strip nut 4024 serves as the final safety guarantee, locking the insertion rod 4013 to prevent its accidental retraction. This "three-in-one" constraint mechanism constitutes multiple insurances, greatly improving the reliability and anti-loosening capability of the connection structure under harsh working conditions such as vibration and impact.

[0016] Based on the above, other structures also need to be disclosed in detail, such as: A connecting rod 4014 is fixedly connected to the side of the slide plate 4012 opposite to the insertion rod 4013. The connecting rod 4014 passes through the side wall of the first rectangular block 4011 and is fixedly connected to a rectangular plate 4015. A semi-circular pull ring 4016 is fixedly connected to the rectangular plate 4015. Two return springs 4017 are symmetrically fixedly connected to the slide plate 4012. The end of each return spring 4017 opposite to the slide plate 4012 is fixedly connected to the inner wall of the first mounting cavity. When the return spring 4017 releases its elastic force, it can push the slide plate 4012 and the insertion rod 4013 to move laterally, so that the insertion rod 4013 can be automatically and quickly inserted into the insertion port of the connecting block 3011.

[0017] A groove is provided on the second rectangular block 4021, and slide rods 4025 are symmetrically fixedly connected to the strip nut 4024. The opposite ends of the two slide rods 4025 are slidably connected to the inner wall of the second mounting cavity. Under the action of the slide rods 4025, the strip nut 4024 moves vertically.

[0018] In summary, the working principle of this solution is as follows: During assembly, the worker inserts their fingers into the semi-circular pull ring 4016 and pulls it outward to pull the insertion rod 4013 out of the connecting groove 201. By aligning the connector head 301 of the connector 3 with the opening at the bottom of the mounting block 2, the conical head 3012 first enters the conical groove 202. Utilizing the self-centering effect of the conical surface, the position of the connector 3 is automatically corrected, ensuring that the connector block 3011 can smoothly pass through the connecting groove 201. When the connector head 301 is installed in place, the insertion port on the connector block 3011 is exactly aligned with the insertion rod 4013 of the first constraint member 401. At this time, the return spring 4017, which is in a compressed state, releases its elastic force, pushing the slide plate 4012 and the insertion rod 4013 to move laterally, so that the insertion rod 4013 automatically and quickly inserts into the insertion port of the connector block 3011, achieving... The first type of constraint—lateral pin constraint—effectively prevents the connector 3 from displacing or detaching in the horizontal and vertically downward directions. After the pin constraint is completed, in order to prevent the insertion rod 4013 from accidentally retracting under vibration or external impact, which would cause the constraint to fail, a secondary locking is required. The operator rotates the rotating plate 4022 of the second constraint component 402, and the screw 4023 rotates accordingly, driving the strip nut 4024 to move vertically downward along the guide of the slide rod 4025. The lower end of the strip nut 4024 acts like a "latch," directly inserting into and passing through the round hole on the insertion rod 4013. This forms the second type of constraint—spiral vertical locking constraint. This constraint firmly "nails" the insertion rod 4013 to its working position, preventing it from moving laterally, thus completely eliminating the possibility of the first constraint failing.

[0019] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
