Furthermore, the described specific features, structures, materials, or properties may be combined appropriately in one or more embodiments or examples.A retractable barrier gate is a tool typically equipped with a retractable mesh panel, which primarily serves as a barrier. By adjusting the extended length of the mesh panel, it can be used in various locations such as doorways, stairwells, courtyards, maintenance areas, and so on. The retractable barrier gate is particularly characterized by its compact storage space and wide adjustable length range.

[0022] With the existing telescopic door barrier, the mesh fabric remains taut after being extended to a certain length solely due to the tensile force between the hook and the spring-loaded roller tube. However, if the central area of ​​the mesh fabric is subjected to an external force, it can be extended further. Therefore, the mesh fabric cannot be fixed and locked in any desired position, which significantly impairs the barrier's function. To solve the aforementioned problems, this embodiment discloses an extendable door barrier 100.

[0023] As in Fig. As shown in Figures 1 to 15, the extendable door barrier 100 in this embodiment comprises the following: a mesh screen 1, on the outside of which at least one first suspension tab 2 is arranged; a spring-loaded roller tube 9, to which the inner side of the mesh screen 1 is connected; and an upper fixing base component 5 and a lower fixing base component 6, each connected to the upper end section and the lower end section, respectively, of the spring-loaded roller tube 9. Furthermore, the upper fixing base component 5 and the lower fixing base component 6 are connected and fixed via a support rod 7. The mesh screen 1 can be wound onto the spring-loaded roller tube 9 and can be released from the spring-loaded roller tube 9 by an external pulling force.

[0024] In this embodiment, the extendable door barrier 100 comprises at least: a mesh cloth 1, on the outside of which a first hook 13 is provided; a spring roller tube 9, to which the inner side of the mesh fabric 1 is connected; a lower fixing base component 6, which is connected to the lower end section of the spring roller tube 9; and an upper fixing base component 5, which is connected to the upper end section of the spring roller tube 9, wherein the upper fixing base component 5 includes a locking mechanism for locking or unlocking the spring roller tube 9 at any desired position. The upper and lower ends of the spring roller tube 9 are each rotatably connected to the upper fixing base component 5 and the lower fixing base component 6, respectively. Simultaneously, the upper fixing base component 5 and the lower fixing base component 6 can also be attached to supports such as walls to fix the extendable door barrier of the present embodiment to the support in the application.

[0025] In the present embodiment, the inside of the grid cloth 1 refers to the left side, as shown in Fig. 3 shown, and the outside refers to the right side, as also shown in Fig. Figure 3 shows that at least one handle element 12 is provided on the outside of the mesh sheet 1. This handle element 12 facilitates the manual winding and unwinding of the mesh sheet 1. At the same time, in its retracted position, it can limit the outer edge of the mesh sheet 1 to prevent excessive retraction.

[0026] To improve the force distribution when extending the mesh panel 1 and to ensure more even unfolding, a second hook 14 is attached to the outside of the mesh panel 1. The first hook 13 and the second hook 14 are positioned in the upper and lower sections, respectively. The handle element 12 is located between the first hook 13 and the second hook 14.

[0027] As in Fig. As shown in Figures 8 to 15, the locking mechanism comprises the following: an upper seat housing, a button 52 and an axle connecting element 55 arranged in the upper seat housing, a locking element 54 bearing against the button 52, and a first spring element 58 connected to the locking element 54; wherein a gear section 551 is provided on the axle connecting element 55, a locking opening 543 is provided on the locking element 54 which engages with the gear section 551, and wherein the first spring element 58 serves to move the locking element 54 away from the axle connecting element 55 when an external force is released, so that the locking opening 543 is separated from the gear section 551, and the button 52 serves to drive the locking element 54 to move closer to or away from the axle connecting element 55.The upper seat housing comprises the following: an upper housing 51 and a lower housing 56, wherein the upper housing 51 and the lower housing 56 are positively connected or fastened by means of screws, and a mounting cavity is formed between them in which the locking mechanism is arranged.

[0028] Furthermore, the locking element 54 has a deflection arm 541, with a pivot bore 542 at one end of the deflection arm 541 and the locking opening 543 at the other end. The pivot bore 542 is rotatably connected to the pivot pin 513 on the upper housing 51, and the spring force direction of the first spring element 58 coincides with the deflection direction of the deflection arm 541. That is, the first spring element 58 serves to pivot the deflection arm 541 with the pivot pin 513 as its pivot point when the external force is released. After pivoting, the locking opening 543 disengages from the gear section 551, thereby eliminating the limiting function for the axle connecting element 55. In this case, the spring roller tube 9 can rotate freely, allowing the mesh fabric 1 to be easily stretched.

[0029] As in Fig. 11 and Fig. As shown in Figure 12, the locking mechanism further comprises a guide base 53 in which a guide groove 531 is provided, and a guide section 523 is provided on the button 52, which is inserted into the guide groove 531, with the button 52 moving back and forth under the guidance of the guide base 53 in the longitudinal direction of the deflection arm 541. This means that the button 52 can be moved horizontally back and forth along the guide groove 531. During this movement, the button 52 is in the unlocked state with the spring roller tube 9 in the first position, and when the button 52 is moved to the second position, it is in the locked state with the spring roller tube 9.

[0030] In particular, the key 52 comprises the following: a limiting section 521, a push-button section 522 connected to the top of the limiting section 521, and a stop section 524 connected to the bottom of the limiting section 521, the stop section 524 bearing against the outside of the deflection arm 541, and the push-button section 522 projecting at least partially from the key opening 511 on the top of the upper housing 51 of the upper seat housing. The limiting section 521 has a plate-like structure and serves to prevent the key 52 from falling out of the key opening 511 of the upper housing 51.

[0031] Furthermore, at least two secondary spring elements 57 are arranged between the base of the guide 53 and the lower housing 56. These secondary spring elements 57 drive the guide 53 upwards, so that the limiting section 521 abuts the inner wall of the upper housing 51. The button 52 is mounted in the guide 53. The base of the guide 53 is acted upon by the spring force of the secondary spring element 57, so that the button 52 is constantly in contact with the inner wall of the upper housing 51. When the push section 522 of the button 52 is actuated, the presence of the secondary spring element 57 ensures a more pleasant feel and smoother operation.Furthermore, the upper fixing base component 5 also has an upper suspension bore 562, and the extendable door barrier further comprises an upper suspension base 8, which includes a suspension base body 81 and an upper hook 82 connected to the suspension base body 81, the upper hook 82 being inserted into the upper suspension bore 562. The upper suspension base 8 is attached to supports such as walls by means of screws or double-sided adhesive tape. The locking mechanism can be quickly connected to the upper suspension base 8 via the upper suspension bore 562 provided in it, and disassembly is also relatively easy.

[0032] To connect and secure the upper fixing base component 5 and the lower fixing base component 6, the extendable door barrier also includes a support rod 7, wherein the upper end of the support rod 7 is connected to the upper fixing base component 5, and the lower end of the support rod 7 is connected to the lower fixing base component 6. A clamping base 4 is also provided at the center of the support rod 7, wherein the clamping base 4 is firmly connected to supports such as walls, and wherein the center of the support rod 7 is positively locked in this clamping base 4.

[0033] In particular, the upper housing 51 also has an upper insertion bore 514 for receiving the support rod 7, and the lower housing 56 has an aligned bore 563. As shown in Fig. 9 and Fig. As shown in Figure 11, the axle connecting element 55 is inserted into the mounting opening 561 of the lower housing 56. This axle connecting element 55 comprises an axle connecting section 552 and a gear section 551, which is arranged near the upper end of the outer wall of the axle connecting section 552. The axle connecting section 552 is inserted into the lower housing 56 through the mounting opening 561, with the gear section 551 securing the axle connecting element 55 in the mounting cavity. A blind groove 512 is also provided in the upper housing 51 to limit the upper end of the axle connecting section 552 and thus improve the rotational stability of the axle connecting element 55.

[0034] In this embodiment, both the first spring element 58 and the second spring element 57 are springs. A connecting pin 544 is further provided at one end of the locking element 54, which is located near the locking opening 543, and one end of the first spring element 58 is fixedly connected to this connecting pin 544. In addition, the extendable door barrier 100 further comprises a first suspension tab 2 and a second suspension tab 3, corresponding to the first hook 13 and the second hook 14, respectively, wherein the first suspension tab 2 and the second suspension tab 3 are fixedly connected to a wall or other support and serve to secure the mesh panel 1 in the extended state.

[0035] Furthermore, the grid fabric 1 has several support strips 10 which serve to increase the vertical support function of the grid fabric. The support strips 10 can either be support structures formed integrally with the grid fabric 1 or separate, subsequently attached clamping support elements.

[0036] The following describes the working sequence of the locking mechanism of the extendable door barrier 100 of this embodiment with further reference to Fig. 1 to 15 briefly described: When the stop section 524 of the button 52 abuts the deflection arm 541 on the side of the joint bore 542, the side of the locking opening 543 of the deflection arm 541 is driven by the first spring element 58. This releases the locking opening 543 from the gear section 551 of the axle connecting element 55. In this case, the axle connecting section 552 can rotate in any direction, and accordingly, the mesh cloth 1 connected to it can be extended or retracted as desired.

[0037] When the button 52 is moved along the guide base 53, causing the stop section 524 to strike the outer wall of the side of the locking opening 543, the stop section 524 drives the deflecting arm 541 to deflect and simultaneously compresses the first spring element 58, so that the locking opening 543 approaches and meshes with the gear section 551. In this case, the axle connecting element 55 is locked by the locking element 54. The locking opening 543 has reverse teeth that mesh with the gear section 551. Regardless of the state of the mesh, it is fixed in its current position. If the mesh 1 is struck by external forces, it does not loosen, remains taut, and exhibits improved defense and protection.

[0038] In the extendable door barrier of the present invention, the locking mechanism is integrated into the upper fixing base component, which is connected to the spring roller tube. The locking mechanism, by means of a combination structure consisting of a button, guide base, locking element, and first spring element, enables the spring roller tube to be locked and fixed in any desired position, thereby fixing the extended mesh fabric in the corresponding position. The locking mechanism itself is simple and reliable, thus ensuring the barrier's locking and protective function. The present invention has been explained in more detail only with reference to embodiments to facilitate the reader's technical understanding. However, this does not mean that the embodiments of the invention are limited to these embodiments.All technical extensions or new developments based on this invention are subject to the scope of protection of the present invention.
