Description

Technical Field

[0001] This utility model relates to the field of inward folding door technology, specifically an inward folding door with a protective mechanism. Background Technology

[0002] An inward-folding door is a special type of folding door design. Its characteristic is that the door leaf folds inward when opened, meaning that the folded door leaf is located inside the doorway. This design ensures that the door does not occupy outdoor space when opened, making it ideal for situations where outdoor space is limited or where it is necessary to keep the outside space unobstructed.

[0003] In actual use, due to the presence of many hinges in inward-folding doors, there are also relatively more gaps in the door. When it is necessary to close the inward-folding door, people often push the protruding hinge part inside the door to close it for convenience. This can easily cause the risk of being pinched. At the same time, inward-folding doors can usually only maintain stability when fully open or fully closed. Without an additional fixing structure, it is difficult to stably control the opening size of the inward-folding door. Utility Model Content

[0004] The purpose of this invention is to provide an inward-folding door with a protective mechanism to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: It includes a fixed door frame and folding door panels. The fixed door frame has a track groove. The folding door panels are arranged in pairs and connected by hinges. Each pair of folding door panels is slidably connected to the track groove on the opposite side via a track block. The track block is rotatably connected to the end of the folding door panel. A vertical rod is fixed to the end of the folding door panel, and a push-pull handle is fixed to the vertical rod. Positioning rods are installed at both the upper and lower ends of the vertical rod. A positioning groove is provided on the fixed door frame at a position corresponding to the positioning rod. The end of the positioning rod is inserted into the positioning groove. A traction rope is provided between the positioning rod and the push-pull handle.

[0006] Preferably, the positioning rod has a hollow groove, and telescopic blocks are slidably connected to both ends of the hollow groove. One end of the positioning rod is fixed to the telescopic block inside the hollow groove. A pull rod is installed inside the push-pull handle, and the two ends of the traction rope are fixed to the pull rod and the telescopic block.

[0007] Preferably, a fixing plate is fixed inside the hollow groove and on the side close to the telescopic block. The fixing plate has a circular ring structure. The traction rope passes through the fixing plate, and a push-out spring is fixed between the fixing plate and the telescopic block.

[0008] Preferably, a pair of guide rods are fixed inside the push-pull handle, and the guide rods pass through the pull rod and are slidably connected to the pull rod.

[0009] Preferably, a through hole is provided on the side wall of the hollow groove at a position corresponding to the pull rod, and a pair of guide wheels are rotatably connected inside the hollow groove at a position aligned with the through hole.

[0010] Preferably, a single-sided baffle is fixed to the outer side of the fixed door frame surface, and the single-sided baffle is located between the track groove and the positioning groove.

[0011] Compared with the prior art, the beneficial effects of this utility model are: when closing the door, the pull rod inside the push-pull handle must be pulled to perform a normal closing operation, avoiding the risk of hand pinching caused by pushing the hinge position, improving the safety of using the inward folding door, and at the same time, when opening, the inward folding door can be opened and closed more stably to the specified size.

[0017] 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.

[0018] Please see Figure 1-4This utility model provides a technical solution: including a fixed door frame 1 and a folding door panel 2. The fixed door frame 1 is provided with a track groove 11. The folding door panels 2 are arranged in pairs and are connected by hinges. Each pair of folding door panels is slidably connected to the track groove 11 by a track block 12 on the opposite side. The track block 12 is rotatably connected to the end of the folding door panel 2. A vertical rod 3 is fixed on the end of the folding door panel 2. A push-pull handle 4 is fixed on the vertical rod 3. Positioning rods 33 are installed at both the upper and lower ends of the vertical rod 3. A positioning groove 13 is provided on the fixed door frame 1 at a position corresponding to the positioning rod 33. The end of the positioning rod 33 is inserted into the positioning groove 13. A traction rope 5 is provided between the positioning rod 33 and the push-pull handle 4. A single-sided baffle 14 is fixed on the outer side of the surface of the fixed door frame 1. The single-sided baffle 14 is located between the track groove 11 and the positioning groove 13.

[0019] A hollow groove 31 is provided inside the positioning rod 33. Telescopic blocks 32 are slidably connected to both ends of the hollow groove 31. One end of the positioning rod 33 is fixed to the telescopic block 32 inside the hollow groove 31. A pull rod 41 is installed inside the push-pull handle 4. The two ends of the traction rope 5 are fixed to the pull rod 41 and the telescopic block 32. A fixing plate 34 is fixed inside the hollow groove 31 and on the side close to the telescopic block 32. The fixing plate 34 has a circular ring structure. The traction rope 5 passes through the fixing plate 34. A push-out spring 35 is fixed between the fixing plate 34 and the telescopic block 32. A pair of guide rods 42 are fixed inside the push-pull handle 4. The guide rods 42 pass through the pull rod 41 and are slidably connected to the pull rod 41. A through hole is provided on the side wall of the hollow groove 31 at the position corresponding to the pull rod 41. A pair of guide wheels 36 are rotatably connected inside the hollow groove 31 and at the position aligned with the through hole.

[0020] Working principle: First, hold the push-pull handle 4 and pull the pull rod 41 to extend and retract the traction rope 5, which in turn pulls the telescopic block 32. When the ejector spring 35 is compressed, the end of the positioning rod 33 is pulled out from the positioning groove 13, releasing the fixation between the upright 3 and the fixed door frame 1. At this time, the front end of the folding door panel 2 can slide freely, realizing the opening of the inward folding door. At the same time, when the pull rod 41 is released, the positioning rod 33 can be pushed out by the reset of the ejector spring 35, so that its end can be re-inserted into the corresponding positioning groove 13, thus fixing the end of the folding door panel 2. The positioning rod 33 can be inserted into different positioning grooves 13 to fix the inward folding door after opening to different sizes. When closing, the hand must be held on the push-pull handle 4 to pull the end of the folding door panel 2 to avoid the risk of pinching the hand when pushing the gap of the folding door panel 2, thus improving the safety of use.
