[0036] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention.

[0037] See Figures 1 to 14 As shown, according to an embodiment of the present invention, a dual-guide assembly assembly is provided. The dual-guide assembly assembly includes an assembly shaft core 10 and an assembly bushing 20. The outer surface of the assembly shaft core 10 is provided with a first guide groove 11 extending in the axial direction and a second guide groove 12 extending in the circumferential rotation direction. The first end of the first guide groove 11 is connected to the first end face of the assembly shaft core 10, and the second end of the first guide groove 11 is connected to the second guide groove 12. The second end of the assembly shaft core 10 is provided with a first limiting structure A1.

[0038] The assembly bushing 20 has an installation channel 21 for inserting the assembly shaft core 10 into the assembly. The inner wall of the installation channel 21 has a first protrusion 22, which matches the first guide groove 11 and the second guide groove 12. The installation channel 21 is also provided with a second limiting structure A2, which is correspondingly provided with the first limiting structure A1.

[0039] When the first end of the assembly shaft 10 is inserted into the mounting channel 21 in the axial direction, the first protrusion 22 and the first guide groove 11 form axial guidance and limitation.

[0040] When the assembly shaft 10 is inserted into the first protrusion 22 and reaches the second guide groove 12, the assembly shaft 10 can rotate circumferentially, and the first protrusion 22 and the second guide groove 12 form circumferential guidance and limitation;

[0041] When the assembly shaft core 10 and the assembly shaft sleeve 20 are fixedly assembled, the first limiting structure A1 and the second limiting structure A2 form a limiting fit.

[0042] In this utility model's dual-guide assembly assembly, during assembly, when the first end of the assembly shaft core 10 is inserted axially into the mounting channel 21, the first protrusion 22 and the first guide groove 11 form an axial guide and limit, creating the first guide assembly structure. This allows the assembly shaft core 10 to be accurately inserted into the assembly bushing and reach a predetermined position. When the assembly shaft core 10 is inserted to the position where the first protrusion 22 reaches the second guide groove 12, the assembly shaft core 10 can rotate circumferentially. The first protrusion 22 and the second guide groove 12 form a circumferential guide and limit, and the length of the second guide groove 12 can limit the rotation angle of the assembly shaft core. The rotation angle can be set according to the length of the second guide groove as needed. When the assembly shaft core 10 is rotated circumferentially, the first limiting structure A1 moves to the second limiting structure A2 and forms a limiting fit. Then, the assembly shaft core is fully inserted into the assembly bushing, thus completing the assembly. During rotation, the cooperation of the first protrusion 22 and the second guide groove 12, along with the limiting cooperation of the first limiting structure A1 and the second limiting structure A2, together form a second guiding assembly structure. This ensures that the assembly shaft core can be accurately assembled into place, making the entire assembly operation more direct and reliable, and solving the problem of difficult assembly. The dual-guide assembly assembly of this invention, through structural cooperation, plays a guiding and limiting role in the assembly process of complex bushing structures. It provides guidance and limitation in both the insertion and rotation directions, preventing misalignment of the assembled parts and allowing for a certain relative rotation angle after assembly, increasing assembly flexibility.

[0043] Preferably, in this embodiment, the first limiting structure A1 is a limiting groove, and the second limiting structure A2 is a second protrusion on the mounting channel 21. Since the assembly shaft is made of a relatively hard material that can deform to a certain extent, such as plastic, selecting the first limiting structure A1 as a limiting groove facilitates the rotation of the assembly shaft at a certain angle. After the assembly shaft is inserted into the mounting channel for a certain distance, during the rotation of the assembly shaft, the first limiting structure A1, as a limiting groove, will not experience excessive friction with the inner wall of the mounting channel or the assembly shaft sleeve, and can smoothly reach the second limiting structure A2 and form a limiting fit (the second protrusion engages in the limiting groove), which is beneficial to assembly efficiency.

[0044] In other embodiments not shown in the figures, the first limiting structure A1 and the second limiting structure A2 can also be interchanged, that is, the first limiting structure A1 is a limiting protrusion and the second limiting structure A2 is a limiting groove. This structural combination has strict requirements for the assembly process, and the corresponding positions of the assembly bushing need to be designed with structural shapes to fit, which can also achieve the technical effect of rapid limiting and fitting.

[0045] In a further preferred embodiment, the second end of the assembly shaft core 10 has an annular protrusion 13, and the annular protrusion 13 has the limiting groove.

[0046] The annular protrusion 13 serves as an auxiliary positioning, guide, and limiter. When the assembly shaft core 10 is inserted into the assembly bushing until the annular protrusion 13 contacts the bushing, the assembly bushing is provided with a matching locking step groove (the end step of the installation channel). When the annular protrusion 13 enters the locking step groove, it provides positioning, guidance, and limiter functions, further preventing assembly misalignment. Furthermore, the limiting groove on the annular protrusion 13 facilitates manufacturing and reduces production costs. The structural position of the first limiting structure A1, in conjunction with the annular protrusion, creates a better limiting effect, preventing loosening after assembly and improving assembly stability.

[0047] Preferably, the first protrusion 22 and the second limiting structure A2 are disposed opposite to each other on both sides of the mounting channel 21;

[0048] The positions of the first guide groove 11 and the second guide groove 12 are located on both sides of the assembly shaft core 10, respectively, as are the positions of the first limiting structure A1.

[0049] The relative positions of the first protrusion 22 and the second limiting structure A2 can limit and lock the assembly shaft core 10 in two relative directions, preventing the assembly shaft core from rotating or loosening after assembly, ensuring the stability of the assembly, and ensuring the structural stability of the complex bushing structure.

[0050] To further ensure the stability of the assembly, see [link / reference]. Figures 10 to 13 In this embodiment, the first end of the assembly shaft core 10 is provided with a plurality of claws 14, which are engaged with the end face of the assembly bushing 20 when the assembly shaft core 10 is installed in place.

[0051] When the assembly shaft core is installed in place, the pawl 14 will pass through the installation channel 21 and engage with the end face of the assembly shaft sleeve 20. When engaging, a snapping sound will be emitted, which will provide feedback to the installer or operator, indicating that the pawl of the assembly shaft core has passed through and engaged in place, reminding the installer or operator to proceed to the next step, thus improving assembly efficiency.

[0052] Preferably, the claws 14 are arranged at intervals along the circumference of the assembly shaft core 10, and the arrangement position of the claws 14 is staggered from the position of the first guide groove 11.

[0053] The arrangement of the claws 14 is offset from the position of the first guide groove 11, ensuring that the assembly shaft is not interfered with by other structures at the beginning of its insertion into the installation channel 21. This allows it to quickly locate the position of the first guiding assembly structure, enabling the first guide groove 11 and the first protrusion 22 to quickly form a fit. After the assembly shaft is in place, the positional relationship between the multiple claws 14 and the first protrusion 22 creates multiple directions for limiting and fixing the assembly shaft, improving the limiting and fixing effect, preventing misalignment or disengagement after assembly, and increasing structural stability. In summary, the arrangement of the claws 14 in conjunction with the position of the first guide groove 11 achieves a multi-functional effect.

[0054] In this embodiment, a flange structure 15 is provided on the annular protrusion 13, and the flange structure 15 is offset from the position of the limiting groove.

[0055] The flange structure 15 serves to provide a means for the installer to continue operating. The flange structure 15 is an operating component; the installer can hold the flange structure 15 by hand to insert and rotate the assembly shaft. The shape of the flange structure 15 can be designed and adjusted according to structural needs; this utility model does not impose specific limitations.

[0056] In other embodiments not shown in the figures, the annular protrusion 13 is provided with two flange structures 15, which are spaced apart and symmetrically arranged. The advantage of the symmetrical arrangement of the two flange structures 15 is that the installer can simultaneously pinch the flange structures 15 to cause a small deformation of the annular protrusion 13, thus facilitating the rotation of the assembly shaft, reducing rotational friction, and increasing assembly speed. Furthermore, the spaced arrangement of the flange structures 15 provides a certain amount of space between them. This space can be used with other pivot structures to limit the rotation angle of the pivot, such as hinges or doors with fixed opening angles. This allows the dual-guide assembly assembly to form structural combinations or combinations with various other complex shaft structures, improving versatility and simplifying the overall structural complexity.

[0057] The dual-guide assembly assembly of this utility model has a wide range of applications. The assembly bushing 20 is located on the structure to be assembled, and the assembly core 10 has an installation groove in the middle, in which a spring is installed.

[0058] The assembly bushing is located on the structure to be assembled and can be connected to the structure by welding or other fixing methods. Alternatively, the assembly bushing itself can be part of the assembly structure. This allows the assembly bushing to be placed on any suitable structure, increasing its versatility and application flexibility. The assembly shaft core 10 has a mounting groove in the middle, which, especially for spring structures, can accommodate the insertion and tightening of the assembly shaft core. This structural fit allows the dual-guide assembly assembly to be used in combinations of spring sleeves, springs, and other structural components, achieving the desired assembly effect and preventing misalignment.

[0059] Application Description of the Dual-Guide Assembly Assembly in One Device: This device is a sealed chamber assembly, which comprises a spring sleeve, a spring, a spring support, a sealed chamber, and a sealed chamber door. The assembly shaft core in the dual-guide assembly assembly is the spring sleeve, which is part of the sealed chamber door (the bushing on the sealed chamber door). During assembly, the end of the assembly shaft core (spring sleeve) that first enters the assembly position is inserted into the assembly bushing (the bushing on the sealed chamber door), thus limiting the rotation angle between the two structures. The rotation angle can be adjusted as needed. During rotation, the second guide assembly structure provides guidance and limitation. After the first and second limiting structures form a limiting engagement, the two assembly structures enter the assembly position. Assembly is complete when the spring sleeve is fully engaged with the bushing on the sealed chamber door, ensuring accurate assembly positioning and improving assembly efficiency.

[0060] In the above applications, the replaceable components are: spring, sealing hatch, and spring bracket. The impact of replacement on the assembly structure is as follows: the spring affects the magnitude of the force on the structure in the design, and an appropriately sized spring can ensure that the structure is firmly assembled; the spring bracket affects the direction of the force on the spring sleeve, ensuring uniform axial force on the assembly structure and avoiding excessive wear around the shaft hole; replacing the hatch has no impact on the structure.

[0061] Expansion and Derivation Directions: The dual-guide assembly component of this utility model can be applied to various revolving door shafts and shaft mating structures with axial limiting. By applying this assembly structure, the components can be guided and limited during axial assembly, preventing misalignment. After assembly, this structure allows for a certain relative rotation angle.

[0062] The dual-guide assembly of this invention has a higher assembly effect than the existing single short guide assembly, saves more material in the production of guide components than the existing single long guide structure, and the components are simpler and lighter.
