[0042] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0043] Example 1: Quick-install structure for telescopic gate shaft

[0044] like Figures 1-6 As shown, a quick-install structure 100 for a telescopic door shaft is used to fix a fixed shaft 200 inside a door frame profile 300. The quick-install structure includes a shaft fixing seat 1 and an elastic element 2.

[0045] One side of the shaft fixing seat 1 is the door frame mounting side 11, which is fixedly installed with the door frame profile, and the other side is the fixed shaft mounting side 12, which is fixedly installed with the fixed shaft. At least one first snap-fit ​​hole 121 is provided on the fixed shaft mounting side, and at least one second snap-fit ​​hole 201 is provided on the fixed shaft 200. The elastic member 2 is installed in the fixed shaft or the shaft fixing seat. The elastic member 2 is provided with a snap-fit ​​part 21. The elastic member 2 is configured to apply a force that causes the snap-fit ​​part to extend out of the first snap-fit ​​hole and the second snap-fit ​​hole, so that the elastic member locks the fixed shaft in the shaft fixing seat.

[0046] This application designs an assembly structure for the shaft fixing seat and elastic element. Specifically, through the snap-fit ​​part of the elastic element within the shaft fixing seat or the fixed shaft, the expansion and contraction of the elastic element ensures both the stability of the fixed shaft and the door frame profile after installation and the ease of assembly of the fixed shaft, reducing the installation time and labor costs of the central shaft. Furthermore, the installation and disassembly processes of the above structure are relatively simple, facilitating subsequent maintenance and repair of the central shaft.

[0047] As a further preferred embodiment, the elastic element is an elastic sheet 22, and the elastic sheet 22 and the snap-fit ​​portion 21 are integrally formed.

[0048] As a further preferred embodiment, the elastic element is a U-shaped elastic sheet 22, and the snap-fit ​​part 21 is located at both ends of the U-shaped elastic sheet and protrudes outward from the far end, forming a marble shape, which is convenient for manual pressing and also convenient for installation.

[0049] There are two first snap-fit ​​holes on the shaft fixing seat, and the number of second snap-fit ​​holes corresponds one-to-one with the number of first snap-fit ​​holes.

[0050] The elastic piece is simple in structure and easy to implement. Specifically, the elastic piece is a metal piece, and the clamping portion can be formed by forging and pressing with the elastic piece or welded on the elastic piece. It can be imagined that the elastic piece can also be a spring, one end of the spring abuts against the clamping portion, thereby exerting a force on the clamping portion to extend the two clamping holes in sequence, and satisfying the locking force of the locking structure.

[0051] As a further preferred solution, the shaft rod fixing seat 1 comprises a door frame mounting sheet 11 and a middle shaft sleeve 12 vertically connected to one side of the door frame mounting sheet. The door frame mounting sheet 11 and the middle shaft sleeve 12 can be integrally formed or welded in later period. The door frame mounting sheet is fixedly installed in the door frame profile through fasteners (not shown in the figure), the first clamping hole is arranged on the middle shaft sleeve, the fixed shaft rod is sleeved or inserted on the middle shaft sleeve, and the hole axes of the first clamping hole and the second clamping hole coincide with each other, the clamping portion on the elastic piece extends out of the first clamping hole and the second clamping hole, so that the elastic piece locks the fixed shaft rod in the shaft rod fixing seat.

[0052] As a further preferred solution, the middle shaft sleeve 12 is provided with an anti-falling groove 122 along the radial direction of the pipe wall, the length distribution direction of the anti-falling groove is consistent with the axial direction of the outer wall of the middle shaft sleeve, and the first clamping hole is located on the anti-falling groove.

[0053] In the present application, the structure design of the anti-falling groove can be concave along the radial direction of the pipe wall of the middle shaft sleeve, that is, the local pipe wall of the middle shaft sleeve is narrowed to the position of the middle axis, so as to increase the locking force of the elastic piece on the overall locking structure and achieve the effect of preventing the elastic piece from falling off.

[0054] As a further preferred solution, the inner side of the door frame profile 300 is provided with a plug-in hole 301 for inserting the middle shaft sleeve and a first fastening hole 302 for fixing the door frame mounting sheet, and the door frame mounting sheet 11 is provided with a second fastening hole 111 matched with the first fastening hole.

[0055] As a further preferred solution, the telescopic door shaft rod quick mounting structure further comprises a decoration piece 3.

[0056] The present application can improve the overall appearance of the telescopic door, hide the connection part, and make the appearance more neat by designing the decoration piece and covering the connection position between the middle shaft rod and the door frame profile.

[0057] As a further preferred solution, the decoration piece 3 has a decoration cover 31, the outer side of the decoration cover is a smooth decoration surface 311, and the inner side of the decoration cover is provided with an Ω-shaped limiting clamping groove 312 matched with the clamping portion of the elastic piece.

[0058] In addition, the application further limits the position of the elastic member clamping part by internally arranging a limiting clamping position on the decoration piece, which can further improve the telescopic stability of the assembled elastic member, reduce the jamming and shaking, and avoid the problem of telescopic incoordination caused by long-term use of the fixed shaft.

[0059] As a further preferred solution, the door frame profile 300 is recessed with a slot 303, the depth of which is the same as the thickness of the decoration cover of the decoration piece, and the width of which is the same as the width of the decoration cover of the decoration piece.

[0060] The application recesses the internal slot on the door frame profile, which can accommodate the decoration piece in the slot and ensure that the telescopic door meets the telescopic movement range of the sliding shaft during the telescopic closing process of the connecting rod mechanism.

[0061] Embodiment 2 includes a telescopic door with a shaft quick-mounting structure

[0062] As shown in Figures 7-8 A telescopic door includes a door body A and a driving system B. The door body A includes a door head A1 and a plurality of door frame profiles A2 / 300 arranged on one side of the door head. The door frame profiles A2 / 300 perform telescopic opening and closing actions under the driving control of the driving system.

[0063] A connecting rod mechanism C is connected between the plurality of door frame profiles A2 / 300. The connecting rod mechanism C is installed in each door frame profile through a sliding shaft C1 and a fixed shaft C2 / 200. The fixed shaft C2 / 200 is fixedly installed in the door frame profile A2 / 300 through the telescopic door shaft quick-mounting structure 100 as described above. The connection relationship and assembly process of the telescopic door shaft quick-mounting structure 100 are described in detail in Embodiment 1 and the accompanying Figures 1-6 The functions and effects are the same as those of the overall telescopic door, and will not be repeated here.

[0064] In summary, the telescopic door of the application can directly insert and assemble the fixed shaft and the door frame profile or disassemble them with the help of simple tools, which is very convenient to operate and brings great convenience to the installation work of the staff, thereby greatly improving the installation efficiency.

[0065] The above embodiments are only preferred embodiments of the present application, and cannot be used to limit the scope of protection of the present application. Any non-essential changes and substitutions made by those skilled in the art on the basis of the present application are within the scope of the present application.
