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

[0037] See also Figures 1 to 14 As shown, according to an embodiment of the present invention, a double-guide assembly component is provided, the double-guide assembly component comprising an assembly shaft core 10 and an assembly shaft sleeve 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 surface 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 sleeve 20 has an installation channel 21 for inserting and assembling the assembly shaft core 10, and the inner wall of the installation channel 21 has a first protrusion 22, and the first protrusion 22 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, and the second limiting structure A2 is arranged corresponding to the first limiting structure A1;

[0039] When the first end of the assembly shaft core 10 is inserted into the installation channel 21 along the axial direction, the first protrusion 22 and the first guide groove 11 form an axial guide and limit;

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

[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] The dual-guide assembly component of the present invention, when assembling, firstly, when the first end of the assembly shaft core 10 is inserted into the installation channel 21 along the axial direction, the first protrusion 22 and the first guide groove 11 form an axial guide and limit, forming a first guide assembly structure, so that the assembly shaft core 10 can be accurately inserted into the assembly sleeve and reach the predetermined position. When the assembly shaft core 10 is inserted into the first protrusion 22 and reaches the second guide groove 12 position, the assembly shaft core 10 can rotate circumferentially, the first protrusion 22 and the second guide groove 12 form a circumferential guide and limit, the length of the second guide groove 12 can limit the rotation angle of the assembly shaft core, and the size of 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 limit structure A1 is moved to the second limit structure A2 and a limit fit is formed, and then the assembly shaft core is completely inserted into the assembly sleeve to be assembled in place. During the rotation process, the cooperation between the first protrusion 22 and the second guide groove 12, and the cooperation between the first limiting structure A1 and the second limiting structure A2 together form a second guide assembly structure, so that the assembly shaft core can be accurately assembled in place, and the entire assembly operation is more direct and reliable, solving the problem of assembly difficulties. The dual-guide assembly component of the present invention plays a guiding and limiting role in the assembly process of complex sleeve-like structures through structural cooperation, and guides and limits in both the insertion direction and the rotation direction to prevent the assembly parts from being misplaced, and allows the assembled structure to have a certain relative rotation angle, 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 installation channel 21. Since the material of the assembly shaft core is a harder material that can be deformed to a certain extent, such as plastic. Therefore, the first limiting structure A1 is selected as the limiting groove, which is conducive to the rotation of the assembly shaft core at a certain angle. After the assembly shaft core is inserted into the installation channel for a certain distance, during the process of rotating the assembly shaft core, the first limiting structure A1, as a limiting groove, will not have too much friction with the inner wall of the installation channel or the assembly sleeve, and can reach the second limiting structure A2 more smoothly and form a limiting fit (the second protrusion is inserted into the limiting groove), which is conducive 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 interchange the structural types, 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 on the assembly process, and the corresponding position of the assembly sleeve needs to be designed with a structural shape to match, which can also achieve the technical effect of rapid limiting matching.

[0045] In the present embodiment, it is further preferred that 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 can play the role of auxiliary positioning, auxiliary guiding and limiting. When the assembly shaft core 10 is inserted into the assembly sleeve until the annular protrusion 13 contacts the assembly sleeve, the assembly sleeve is provided with a positioning step groove (the end step of the installation channel) matching the annular protrusion. When the annular protrusion 13 enters the positioning step groove, it plays the role of positioning, guiding and limiting, further preventing the problem of assembly misalignment. Moreover, the limiting groove is provided on the annular protrusion 13, which can facilitate processing and manufacturing, reduce production costs, and the structural position of the first limiting structure A1 cooperates with the annular protrusion to form a better limiting effect, prevent loosening after assembly, and improve assembly stability.

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

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

[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 to prevent the assembly shaft core from rotating or loosening after being assembled, thereby ensuring the stability of the assembly and the structural stability of the complex sleeve-like structure.

[0050] To further ensure the stability of the assembly, see Figures 10 to 13 In this embodiment, a plurality of claws 14 are provided at the first end of the assembly shaft core 10 , and the claws 14 are clamped on the end surface of the assembly sleeve 20 when the assembly shaft core 10 is installed in place.

[0051] When the assembly shaft core is installed in place, the claw 14 will pass through the installation channel 21 and engage with the end face of the assembly sleeve 20, and make a snapping sound during the engagement, which is fed back to the installer or operator, indicating that the claw of the assembly shaft core has passed through and engaged in place, reminding the installer or operator to proceed to the next step, thereby improving assembly efficiency.

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

[0053] The arrangement position of the clamping claw 14 is staggered with the position of the first guide groove 11, so that the assembly shaft core will not be interfered by other structures when it is inserted into the installation channel 21, and the position of the first guide assembly structure can be quickly found, so that the first guide groove 11 and the first protrusion 22 can quickly form a match. After the assembly shaft core is assembled in place, the positional relationship between the multiple clamping claws 14 and the first protrusion 22 forms a limit fixation for the assembly shaft core in multiple directions, which improves the limit fixation effect, prevents misalignment or disengagement after assembly, and increases structural stability. In summary, the arrangement position of the clamping claw 14 is matched with the position of the first guide groove 11, which achieves the effect of one thing with multiple uses.

[0054] In this embodiment, a flange structure 15 is disposed on the annular protrusion 13 , and the flange structure 15 and the limiting groove are staggered in position.

[0055] The flange structure 15 is provided for the installation personnel to continue the operation. The flange structure 15 is an operating component. The installation personnel can pinch the flange structure 15 by hand to insert the assembly shaft core and rotate the assembly shaft core. The shape of the flange structure 15 can be designed and adjusted according to the structural requirements, and the present invention does not make specific restrictions.

[0056] In other embodiments not shown in the figure, two flange structures 15 are arranged on the annular protrusion 13, and the two flange structures 15 are arranged at intervals and symmetrically. The advantage of the symmetrical arrangement of the two flange structures 15 is that the installer can pinch the flange structures 15 at the same time to cause a smaller deformation of the annular protrusion 13, which is convenient for rotating the assembly shaft core, reducing the friction of the rotation and increasing the assembly speed. Moreover, the flange structures 15 are arranged at intervals so that there is a certain space between the two flange structures. This part of the space can cooperate with other rotating shaft structures to limit the rotation angle of the rotating shaft, such as hinges or doors with fixed opening angles, so that the dual-guide assembly component can form a structural combination or structural coordination with other various complex shaft structures, thereby improving versatility and simplifying the complexity of the overall structure.

[0057] The dual-guide assembly component of the present invention has a very wide range of application scenarios. The assembly sleeve 20 is located on the structure to be assembled, and a mounting groove is provided in the middle of the assembly shaft core 10, and a spring is installed in the mounting groove.

[0058] The assembly sleeve is located on the structure to be assembled, and can be connected to the structure to be assembled by welding or other fixing methods. The assembly sleeve itself may also be a part of the structure with the assembly structure. The assembly sleeve can be set on any structure that meets the requirements, and the structure has higher versatility and application flexibility. An installation groove is provided in the middle of the assembly shaft core 10, and in particular, the spring structure can adapt to the insertion and rotation of the assembly shaft core. The above-mentioned structural coordination enables the dual-guide assembly component to be applied to structural combinations such as spring sleeves and springs. The assembly effect meets the requirements and can prevent assembly misalignment.

[0059] Application description of the double-guide assembly component in one of the devices: The device is a sealed cabin component, which includes a spring sleeve, a spring, a spring bracket, a sealed cabin, and a sealed cabin door. The assembly shaft core in the double-guide assembly component is a spring sleeve, and the assembly sleeve is a part of the sealed cabin door (the sleeve on the sealed cabin door). During assembly, the assembly shaft core (spring sleeve) first enters the assembly position and is inserted into the assembly sleeve (the sleeve on the sealed cabin door), which can limit the rotation angle between the two structures. The size of the rotation angle can be adjusted as needed. During the rotation process, the second guide assembly structure performs the guide restriction. After the first limiting structure and the second limiting structure form a limiting match, the two assembly structures enter the assembly position. When the spring sleeve is completely inserted into the sleeve on the sealed cabin door, the assembly is in place, thereby ensuring the accuracy of the assembly position and improving the assembly efficiency.

[0060] In the above application, the replaceable parts are: spring, sealed hatch, spring bracket, and the impact on the assembly structure after replacement is as follows: the spring affects the force magnitude of the structure of this invention in the scheme, and a spring of appropriate size can ensure that the structure is assembled firmly; the spring bracket affects the force direction of the spring sleeve, ensuring that the axial force of the assembly structure is uniform and avoiding excessive wear around the shaft hole; hatch replacement has no effect on the structure.

[0061] Expansion and derivation direction: The dual-guide assembly assembly of the present invention can be used in various types of rotating door shafts and shaft matching structures with axial limit. The secondary assembly structure can play a guiding and limiting role in the axial assembly process of the components to prevent the assembly parts from being misplaced. After the assembly of this structure, the assembled structure is allowed to have a certain relative rotation angle.

[0062] The double-guide assembly component of the present invention has a higher assembly effect than the existing single short guide component, saves more guide component manufacturing materials than the existing single long guide structure, and the components are simpler and lighter.
