Description

Technical Field

[0001] This utility model relates to the field of hinge technology, and in particular to a hinge with self-cleaning function for steel doors. Background Technology

[0002] Hinges are the core pivotal components that enable the opening and closing of doors. They connect the door to the door frame and allow the door to rotate around the pivot. For steel doors, especially those used in industrial environments, outdoors, or fire-resistant compartments, their weight is usually large, and the operating environment is relatively complex, which places high demands on the structural stability and durability of the hinges.

[0003] During daily use, the pivot components and structural gaps of a hinge are inevitably exposed to the environment. In dusty or outdoor environments, dust, grit, and other foreign objects can easily accumulate at the hinge's moving joints.

[0004] These accumulated foreign objects significantly increase the hinge's rotational resistance, causing the door to open and close poorly and produce abnormal noises. More seriously, these hard particles act as abrasives, accelerating wear on the pivot components when the door rotates, severely shortening the hinge's lifespan, and potentially causing the door to sag.

[0005] Currently, solving this problem mainly relies on regular manual cleaning and lubrication. However, this passive cleaning method is often untimely and increases the burden and cost of maintenance. Existing steel door hinges generally do not consider how to actively prevent or remove these accumulated foreign objects in their structural design, lacking a mechanism for automatic cleaning during daily use.

[0006] Therefore, this utility model proposes a hinge with self-cleaning function for steel doors to overcome the shortcomings of the prior art. Utility Model Content

[0007] In view of the problems in the existing technology of self-cleaning hinges for steel doors, such as the easy accumulation of dust and foreign objects in the moving joints, which leads to stuck rotation, accelerated wear, and lack of automatic cleaning mechanism, relying on manual passive maintenance, this utility model aims to provide a self-cleaning hinge for steel doors with an improved structure that can effectively solve the above problems.

[0008] This utility model provides a self-cleaning hinge for steel doors, comprising: a base post, an opening plate pivotally mounted on the base post, a closing plate, and a top post connecting the closing plate; the closing plate has screw holes. The hinge also includes a wear-compensating mechanism. The wear-compensating mechanism includes a thrust member, a wear-resistant ring, a support plate, a scraper, bristles, a linkage rod, a slide rail, and a cylinder. The base post has an inner groove in which the thrust member of the wear-compensating mechanism is accommodated, and the thrust member is used to push the wear-resistant ring upwards to achieve wear compensation. Furthermore, the support plate of the wear-compensating mechanism is fixedly connected to the opening plate, and a slide rail is provided on the support plate. The scraper of the wear-compensating mechanism is slidably connected to the slide rail via a cylinder on it; the bristles are fixedly connected to the scraper; one end of the linkage rod of the wear-compensating mechanism is connected to the scraper, and the other end is connected to the base post, used to drive the scraper to move along the slide rail when the opening plate rotates, thereby achieving an automatic cleaning function.

[0009] Preferably, the hinge further includes a connecting block and a locking mechanism; the connecting block is connected to the top post, and the connecting block has a groove and a slot; the opening plate is adapted to be inserted into the groove; the locking mechanism is set inside the opening plate, and the locking mechanism includes a locking block and a spring, the spring being used to drive the locking block to engage in the slot, so as to realize the separable locking of the opening plate and the connecting block.

[0010] Preferably, as a specific implementation of the locking mechanism, the locking mechanism also includes a locking element; a sliding groove is provided in the opening plate; the locking block is slidably connected to the sliding groove, and the locking block is driven by the locking element to realize the extension and retraction of the locking tongue.

[0011] Preferably, to improve the operational stability of the locking mechanism, the locking mechanism further includes a horizontal column; a fixing groove is provided inside the locking block; a spring is sleeved on the horizontal column, and the horizontal column is slidably connected to the fixing groove to guide and limit the movement of the spring.

[0012] Preferably, to improve the stability of wear compensation, the support mechanism also includes a column; a limiting groove that matches the column is provided in the wear-resistant ring; the column is sleeved in the thrust member and slidably connected to the limiting groove to guide the pushing motion of the thrust member and prevent it from jamming or deviating.

[0013] Preferably, the thrust element is an elastic telescopic element, which is pre-compressed and installed in the inner groove to ensure that it can continuously provide upward compensating elastic force.

[0014] Preferably, the hinge also includes a groove assembly, which is a collection of groove structures in the hinge used to achieve functions such as guiding, fitting, and locking. It includes slides, fixing grooves, recesses, slots, slides, and cylinders.

[0015] Preferably, the bristles are made of a flexible material that can adapt to uneven surfaces on the hinge to improve cleaning coverage and cleaning effect.

[0016] This utility model has the following beneficial effects:

[0017] 1. This utility model, by setting up a support mechanism, uses a thrust member housed in the bottom column to continuously push the wear-resistant ring, which solves the problem in the prior art where the wear-resistant parts of the hinge wear due to long-term load-bearing rotation, thus causing the door to sag. It achieves the technical effect of automatically compensating for wear gaps, ensuring stable operation of the door and extending the service life of the equipment.

[0018] 2. This utility model, by setting a scraper, brush bristles and linkage rod in the support mechanism, uses the opening and closing action of the door to drive the brush bristles to reciprocate in the slide of the support plate, which solves the problem that the hinges in the prior art are prone to accumulating dust and foreign objects, resulting in rotation jamming, noise and accelerated wear. It achieves the technical effect of automatically cleaning the hinge surface, preventing the accumulation of foreign objects, maintaining smooth rotation and reducing manual maintenance.

[0019] 3. This utility model, by setting a locking mechanism, uses a spring to drive the locking block to retract and lock into the slot of the connecting block, realizing the separable connection between the opening plate and the connecting block.

[0020] 4. This utility model solves the problem of possible skewing, jamming or falling off of moving parts such as springs, thrusters and scrapers during movement by setting sliding cooperation between the column and the limiting groove, the horizontal column and the fixing groove, and the cylinder and the slide in the locking mechanism and the holding mechanism, respectively. It achieves the technical effect of ensuring that each mechanism runs stably along the predetermined trajectory and improving the reliability and durability of the entire hinge device.

[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0032] Example:

[0033] Please refer to Figures 1 to 4 This utility model provides a hinge with self-cleaning function for steel doors, which aims to solve the problems in the prior art such as the lack of automatic compensation when the door sags due to wear of the steel door hinge, the easy accumulation of dust in the hinge components causing jamming and lack of automatic cleaning, and the complex structure of door installation and disassembly.

[0034] like Figure 1 and Figure 4 As shown, the hinge includes a base post 1, a split plate 2, a mating plate 6, and a top post 5. The split plate 2 is pivotally mounted on the base post 1. The mating plate 6 has screw holes 7. The top post 5 is connected to the mating plate 6.

[0035] The hinge is equipped with a support mechanism 4, which includes an inner groove 42, a thrust member 41, a column 43, a wear-resistant ring 45, and a limiting groove 44, all located within the base column 1. The thrust member 41 is an elastic telescopic member, which is pre-compressed and installed within the inner groove 42. The wear-resistant ring 45 is located between the base column 1 and the opening plate 2. The thrust member 41 is used to push the wear-resistant ring 45 upward. A limiting groove 44 is provided within the wear-resistant ring 45. The column 43 is sleeved within the thrust member 41 and slidably connected to the limiting groove 44.

[0036] The support mechanism 4 also includes a support plate 46, a scraper 47, bristles 48 and a linkage rod 49. The support plate 46 is fixedly connected to the opening plate 2. The scraper 47 is fixedly connected to the bristles 48, which are made of flexible material to adapt to the unevenness of the hinge surface. One end of the linkage rod 49 is connected to the scraper 47 and the other end is connected to the bottom column 1.

[0037] Reference Figures 1 to 3 The hinge also includes a connecting block 35 and a locking mechanism 3. The connecting block 35 is connected to the top post 5, and the locking mechanism 3 is located inside the opening plate 2. The locking mechanism 3 includes a locking element 31, a locking block 32, a spring 33, and a cross post 34. The hinge also includes a groove assembly 36, which includes a sliding groove 361, a fixing groove 362, a recess 363, a locking groove 364, a sliding track 365, and a cylinder 366. The support plate 46 has a sliding groove. The slide 365 is connected to the scraper 47 via the cylinder 366; the block 35 has a groove 363 and a slot 364; the opening plate 2 has a slide groove 361, the slot 32 is slidably connected to the slide groove 361, the locking piece 31 is set on the opening plate 2 and drives the locking piece 32; the locking piece 32 has a fixing groove 362, the horizontal column 34 is slidably connected to the fixing groove 362, and the spring 33 is sleeved on the horizontal column 34.

[0038] Reference Figures 1 to 4 The support mechanism 4 includes a pre-compressed thrust member 41 installed in the inner groove 42 of the base column 1, and a wear-resistant ring 45 located between the pivot contact surfaces of the base column 1 and the opening plate 2. The thrust member 41 continuously applies an upward pushing force to the bottom of the wear-resistant ring 45. When the wear-resistant ring 45 wears due to long-term use, the thrust member 41 will automatically extend to lift the wear-resistant ring 45, thereby compensating for the height lost due to wear and ensuring the stable support of the hinge. To ensure the stability of the movement of the thrust member 41, a limiting groove 44 is opened at the bottom of the wear-resistant ring 45. At the same time, a column 43 is fixedly connected to the thrust member 41, and the top of the column 43 is slidably connected in the limiting groove 44. This sliding fit structure guides and limits the extension and retraction movement of the thrust member 41, effectively preventing it from deviating or getting stuck.

[0039] The support mechanism 4 includes a support plate 46 fixedly connected to the opening plate 2, a slide rail 365 on the support plate 46, and a scraper 47 with bristles 48 fixedly connected to it and slidably connected to the slide rail 365 via the cylinder 366. The support mechanism 4 also includes a linkage rod 49, one end of which is rotatably connected to the bottom column 1 and the other end of which is rotatably connected to the scraper 47. In the assembled state, when the opening plate 2 rotates around the bottom column 1, the linkage rod 49 drives the scraper 47 and the bristles 48 thereon to move along a predetermined trajectory under the guidance of the slide rail 365. This linkage structure utilizes the power of the door opening and closing to enable the bristles 48 to automatically clean the dust on the hinge surface, thus achieving a self-cleaning function.

[0040] The hinge also includes a connecting block 35 and a locking mechanism 3. The connecting block 35 is connected to the top post 5. The connecting block 35 has a groove 363 and a slot 364. The opening plate 2 is adapted to insert into the groove 363. The locking mechanism 3 is set in the opening plate 2. The locking mechanism 3 includes a locking block 32 and a spring 33. The spring 33 drives the locking block 32 to engage with the slot 364 to achieve locking. The locking mechanism 3 also includes a locking element 31. The opening plate 2 has a sliding groove 361. The locking block 32 is slidably connected to the sliding groove 361. The locking block 32 is driven by the locking element 31 to achieve the retraction of the locking mechanism. The locking mechanism 3 also includes a horizontal post 34. The locking block 32 has a fixing groove 362. The spring 33 is sleeved on the horizontal post 34. The horizontal post 34 is slidably connected to the fixing groove 362 to prevent the spring 33 from deflecting when compressed or released. The thrust element 41 in the holding mechanism 4 is an elastic telescopic element. The thrust element 41 is pre-compressed and installed in the inner groove 42.

[0041] The implementation principle of this application embodiment is as follows: When the door needs to be locked, by pressing the locking piece 31, the locking block 32 connected to the locking piece 31 is driven to move. At this time, the locking block 32 will slide in the sliding groove 361 opened in the opening plate 2. At the same time, the movement of the locking block 32 will compress the spring 33 connected to the inner wall of the opening plate 2. The spring 33 will generate a reaction force to pop out the locking block 32. At the same time, the horizontal column 34 sleeved on the spring 33 will slide in the fixing groove 362 opened in the locking block 32, effectively preventing equipment damage caused by the locking when the spring 33 moves. At this time, the opening plate 2 is aligned with the groove 363 opened in the connecting block 35 and inserted. At this time, the locking piece 31 is released, and the locking block 32 will automatically pop out under the action of the spring 33 and slide into the locking groove 364 opened in the connecting block 35. At this time, the door has been installed. The locking mechanism 3 and the groove assembly 36 achieve quick disassembly of the door. The top column 5 is connected to the connecting plate 6. The connecting plate 6 has screw holes 7. The equipment is fixed by driving in screws.

[0042] When the door rotates, the wear-resistant ring 45 will wear down. At this time, the continuously compressed thrust member 41 in the inner groove 42 opened in the bottom column 1 will move, lifting the wear-resistant ring 45. At the same time, the column 43 fitted with the thrust member 41 slides in the limiting groove 44 opened in the wear-resistant ring 45, effectively preventing the equipment from being damaged by the thrust member 41 getting stuck. At the same time, when the equipment is opened and closed, the scraper 47 will move. At this time, the cylinder 366 connected to the scraper 47 will slide in the slide 365 opened on the support plate 46 connected to the opening plate 2, ensuring the smooth operation of the equipment. At the same time, the linkage rod 49 plays a connecting role. At this time, the bristles 48 connected to the scraper 47 have soft characteristics, which can adapt to the unevenness of the hinge surface and increase the dust removal effect. Through the effect of the holding and replenishing mechanism 4, the wear-resistant ring 45 is continuously replenished, effectively extending the service life of the equipment.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
