Description

Technical Field

[0001] The invention belongs to the field of elevator accessories, in particular to a light and thin high-strength sill. Background Art

[0002] An elevator is a permanent transportation device that serves several specific floors in a building and whose car runs on at least two rows of rigid rails that are perpendicular to the horizontal plane or have an inclination angle of less than 15° to the plumb line.

[0003] There are also stepped types, with the treads mounted on tracks and running continuously, commonly known as escalators or moving walkways. A fixed lifting device that serves a specified number of floors.

[0004] A vertical elevator consists of a car that travels between at least two vertical rigid guide rails, or rails inclined at an angle of less than 15°. The car's size and structure facilitate passenger entry and exit, as well as loading and unloading of goods. Elevators are generally considered a general term for vertical transportation within a building, regardless of their drive method.

[0005] There are many accessories in an elevator, and it requires a lot of auxiliary devices to cooperate when in use. Among them, the more common ones are elevator sills that limit the elevator doors and ensure the stability of the elevator doors' operation.

[0006] The traditional elevator sill is a strip structure with a slide;

[0007] For example, Chinese invention patent CN102390776B discloses an elevator sill, in which the sill body, first side arm, second side arm, first bottom bracket and second bottom bracket are arranged in one piece, and the second bottom bracket has a partially concave upward to form a reinforcing groove, which not only strengthens the sill strength, but also makes the sill beautiful, simple and generous in appearance, and truly practical, thereby solving the shortcomings of existing sills such as low strength, easy deformation, and the need for regular inspection and maintenance. In addition, the present invention adopts an integral stainless steel structure, which not only increases strength and reduces manufacturing costs, but also simplifies manufacturing and makes installation and maintenance convenient and quick.

[0008] After research, it was found that the above-mentioned elevator sill has certain disadvantages when used;

[0009] The above-mentioned elevator sill uses a groove-shaped structure to guide and limit the elevator door. When in use, it is affected by various forces such as gravity, friction, and collision, and the structures on the elevator door and the elevator sill will undergo certain deformation. This new type of structure will hinder the opening and closing of the elevator door and generate a lot of noise. In this case, the elevator sill is usually replaced directly, which requires high costs and a certain amount of time, seriously affecting people's travel and not meeting people's usage requirements.

[0010] The above-mentioned elevator sill adopts a groove-shaped structure to guide and limit the elevator door. During long-term use, a large amount of debris will pass through the gap between the elevator door and the ground and enter the slide. However, due to the limited width of the slide and the thick elevator door, the lower end of the elevator door will completely block the slide. Therefore, normal cleaning cannot clean the debris in the slide. Over a long period of use, a large amount of debris will accumulate in the slide, and these debris are difficult to clean, which easily causes the elevator door to jam, which does not meet people's usage requirements.

[0011] In summary, since the existing elevator sill has great drawbacks when used and does not meet people's usage requirements, people have invented an elevator sill. Summary of the Invention

[0012] In order to overcome the shortcomings of the existing technology, the embodiment of the present application provides a light and thin high-strength sill, which can solve the technical problems thereof. The technical solution adopted is:

[0013] A light, thin, high-strength sill, comprising a sill body and a sliding member:

[0014] A slideway is provided near the middle of the upper end surface of the sill body;

[0015] The sliding member is slidably installed in the slideway, and the upper end surface of the sliding member is fixedly connected to the elevator door;

[0016] Wherein, the sliding member includes a slider and a connecting plate:

[0017] The slider is slidably installed inside the slideway;

[0018] The lower end surface of the connecting plate is fixedly connected to the upper end surface of the slider, and the upper end surface of the connecting plate is fixedly connected to the elevator door;

[0019] The sill body comprises a first portion, a middle elastic portion and a second portion, and the side surface of the first portion, the upper end surface of the middle elastic portion and the other side surface of the second portion form a slideway.

[0020] The present invention records a lightweight, high-strength sill, in which the slide on the sill body is composed of the side surface of part No. 1, the upper end surface of the middle elastic part and the other side surface of part No. 2. The middle elastic part is used to support part No. 1 and part No. 2, so that there is a certain adjustment range between part No. 1 and part No. 2. During long-term use, the distance between part No. 1 and part No. 2 can be fine-tuned, thereby avoiding collision between the slider and the slide, effectively reducing noise, and effectively extending the service life of the sill.

[0021] Preferably, the middle elastic portion is an elastic strip, and the end surface of the elastic strip is arc-shaped.

[0022] The end face of the elastic strip is arc-shaped, and the distance between the first part and the second part can be changed by changing the pressure applied to the elastic strip.

[0023] Preferably, a side surface of the No. 1 part and another side surface of the No. 2 part are provided with strip grooves near the lower end, and both sides of the elastic strip are integrally formed with limit strips, which are inserted into the strip grooves, and the upper end surface of the elastic strip is provided with several groups of bolt holes at equal intervals.

[0024] The limit strip is inserted into the strip groove, and after insertion, it is fixed by friction and will not loosen easily.

[0025] Part one, part two and the middle elastic part are designed to be split, which makes it easier to install the slider during installation.

[0026] When in use, install the bolt into the bolt hole on the elastic bar. When in use, tighten the bolt, and the bolt moves downward, which will squeeze the upper end surface of the elastic bar, causing the elastic bar to deform, which will push the No. 1 and No. 2 parts to move sideways, thereby changing the distance between the No. 1 and No. 2 parts.

[0027] Preferably, a limit blocking strip is integrally formed on the side surface of the No. 1 portion and the other side surface of the No. 2 portion, and the limit blocking strip is located above the slider.

[0028] The setting of the limit blocking strip can apply force from above, which can effectively prevent the elevator door from separating from the slide, achieving a long-term positioning effect.

[0029] Preferably, a plurality of groups of arc-shaped protrusions are fixedly mounted on the outer surface of the slider, and the protrusions fit in contact with the inner side wall of the slideway.

[0030] The raised setting can reduce friction.

[0031] The present invention records a lightweight and high-strength sill, on which a limit blocking strip is integrally formed on the side of the No. 1 part and the other side of the No. 2 part. The limit blocking strip is located above the slider. The use of the limit blocking strip further above the slider can provide a better supporting effect and can effectively prevent the slider from detaching from the slide when the door is deformed due to impact. It has good use effect and has good prospects for use.

[0032] Preferably, a cavity for storing sundries is provided inside the No. 2 part, and a plurality of groups of openings are provided on the other side of the No. 2 part. The plurality of groups of openings are arranged at equal intervals, and the cavities are connected to each other through the openings.

[0033] The cavity can accommodate a certain amount of debris, which can reduce the impact of the debris on the movement of the slider.

[0034] Preferably, the front end face and the rear end face of the slider are both provided with push blocks, and the push blocks are tilted away from one end face of the slider.

[0035] The push block is tilted to shovel debris in the slideway, separating the debris from the inner wall of the slideway. At the same time, its tilted surface can guide the movement of the debris, so that the debris moves into the interior of the cavity.

[0036] Preferably, a guide block is fixedly installed on the other side of the No. 2 part, and the number of the guide blocks is several groups, and the guide blocks in the several groups are arranged at equal intervals on the other side of the No. 2 part.

[0037] The guide block and the push block cooperate with each other. The combination of the two can enable most debris to pass through the opening and fall into the interior of the cavity, thereby effectively reducing the debris in the slideway and making the movement of the slider more stable and smooth.

[0038] Preferably, a through opening is provided on the upper end surface of the second portion near the front end, and the lower end of the through opening is connected to the interior of the cavity.

[0039] The setting of the through-port can facilitate its connection with the dust collection device, and the debris stored in the cavity can be directly extracted through the through-port to achieve a cleaning effect.

[0040] The present invention records a lightweight, high-strength sill, which records a cavity, and the cavity is connected to the slide, and a push block is arranged on the slider. This arrangement enables the slider to scrape off most of the debris and push it into the cavity during operation. Combined with the arrangement of the opening, it can extract the debris, thereby effectively avoiding the interference of the debris on the operation of the elevator door, improving the smoothness of the use of the elevator door, and has good use prospects.

[0041] Preferably, the other side surface of the No. 1 portion and the side surface of the No. 2 portion are both integrally formed with a reinforcement strip, and the reinforcement strip is bent away from the middle elastic portion.

[0042] There are multiple groups of reinforcing strips, which can effectively increase the strength of the sill. The reinforcing strips are bent to limit the positions of the No. 1 and No. 2 parts, avoiding excessive squeezing of the middle elastic part when it is deformed under force.

[0043] In summary, the present invention includes at least one of the following beneficial technical effects:

[0044] First, the present invention records a lightweight and high-strength sill, in which the slide on the sill body is composed of the side of part No. 1, the upper end face of the middle elastic part and the other side of part No. 2. The middle elastic part is used to support part No. 1 and part No. 2, so that there is a certain adjustment range between part No. 1 and part No. 2. During long-term use, the distance between part No. 1 and part No. 2 can be fine-tuned, thereby avoiding collision between the slider and the slide, effectively reducing noise, and effectively extending the service life of the sill.

[0045] Secondly, the present invention records a light and thin high-strength sill, on which a limit blocking strip is integrally formed on the side of the No. 1 part and the other side of the No. 2 part.

It has good use effect and good prospects for use.

[0046] Third, the present invention records a light and thin high-strength sill, which records a cavity, and the cavity is connected to the slide, and a push block is arranged on the slider. This arrangement enables the slider to scrape off most of the debris and push it into the cavity during operation. Combined with the setting of the through opening, it can extract the debris, thereby effectively avoiding the interference of debris on the operation of the elevator door, improving the smoothness of the use of the elevator door, and has good use prospects.

[0057] The embodiment of the present application provides a light, thin, and high-strength sill to solve the problem that the existing elevator sill uses a groove-shaped structure to guide and limit the elevator door. When in use, it is affected by various forces such as gravity, friction, and collision, and the structures on the elevator floor door and the elevator sill will produce a certain amount of deformation. This new type of structure will make the elevator door opening and closing blocked and generate a lot of noise. In this case, the elevator sill is usually replaced directly, which requires a relatively high cost and a certain amount of time, seriously affecting people's travel. In addition, the existing elevator sill uses a groove-shaped structure to guide and limit the elevator door. During long-term use, a large amount of debris will pass through the gap between the elevator door and the ground and enter the slide. However, due to the limited width of the slide and the thick elevator door, the lower end of the elevator door will completely block the slide. Therefore, normal washing cannot clean the debris in the slide. Over long-term use, a large amount of debris will accumulate in the slide, and these debris are difficult to clean, which easily causes the elevator door to jam.

[0058] The patent discloses a light and thin high-strength sill in which the slide on the sill body is composed of the side surface of the first part, the upper end surface of the middle elastic part and the other side surface of the second part. The middle elastic part is used to support the first and second parts, so that there is a certain adjustment range between the first and second parts. During long-term use, the distance between the first and second parts can be fine-tuned, thereby avoiding collision between the slider and the slide, effectively reducing noise, and effectively extending the service life of the sill. It can effectively solve the problem that the elevator door is easily blocked when opening and closing, which will generate a lot of noise.

[0059] The present invention records a lightweight, high-strength sill, which records a cavity, and the cavity is connected to the slide, and a push block is arranged on the slider. This arrangement enables the slider to scrape off most of the debris and push it into the cavity during operation. Combined with the arrangement of the through opening, it can extract the debris, thereby effectively avoiding the interference of the debris on the operation of the elevator door, improving the smoothness of the use of the elevator door, and has good usage prospects. It can solve the shortcomings of being difficult to clean up the debris and easily causing the elevator door to get stuck.

[0060] Example 1:

[0061] A thin and light high strength sill, such as Figure 1-Figure 7 As shown, it includes a sill body 1 and a sliding member:

[0062] A slide 2 is provided near the middle position on the upper end surface of the sill body 1 for guiding the movement of the elevator door; the sliding member is slidably installed in the slide 2, and the upper end surface of the sliding member is fixedly connected to the elevator door; the sliding member includes a slider 3 and a connecting plate 4: the slider 3 is slidably installed inside the slide 2, and the combination of the slider 3 and the slide 2 is an existing commonly used structure, which has a good guiding effect and can be used for a long time; the lower end surface of the connecting plate 4 is fixedly connected to the upper end surface of the slider 3, and the upper end surface of the connecting plate 4 is fixedly connected to the elevator door, and the connecting plate 4 is connected to the inside of the elevator door, and its fixing effect is good and will not loosen easily; the sill body 1 includes part No. 1, an intermediate elastic part and part No. 2, and the side surface of part No. 1, the upper end surface of the intermediate elastic part and the other side surface of part No. 2 constitute the slide 2.

[0063] The side section of the No. 2 part and the other side end face of the No. 1 part can be tilted near the upper end. If the tilted setting is adopted, there will be no obstruction and the use effect will be better.

[0064] If the side section of part No. 2 and the other side end face of part No. 1 near the upper end adopt the structure shown in the figure, grooves need to be cut during installation so that the upper end faces of part No. 2 and part No. 1 are flush with the ground. In this case, there will be no obstruction and the use effect will be better.

[0065] The present invention records a lightweight and high-strength sill, in which the slide 2 on the sill main body 1 is composed of the side surface of the No. 1 part, the upper end surface of the middle elastic part and the other side surface of the No. 2 part. The middle elastic part is used to support the No. 1 part and the No. 2 part, so that there is a certain adjustment range between the No. 1 part and the No. 2 part. During long-term use, the distance between the No. 1 part and the No. 2 part can be fine-tuned, thereby avoiding the collision between the slider 3 and the slide 2, effectively reducing noise, and thus effectively extending the service life of the sill.

[0066] The sill body 1 is divided into three parts: part 1, middle elastic part and part 2. The weight and volume of each part are smaller than the volume of the existing sill. Therefore, each part is relatively light and thin and can be easily carried.

[0067] Example 2:

[0068] On the basis of Example 1, Figures 1-8 As shown, this embodiment shows the structure of the middle elastic part;

[0069] The middle elastic part adopts an elastic strip 10, the end surface of the elastic strip 10 is arc-shaped, and the elastic strip 10 is made of metal. Its deformation can expand to both sides.

[0070] The end surface of the elastic strip 10 is arc-shaped, and the distance between the first part and the second part can be changed by changing the pressure applied to the elastic strip 10.

[0071] A strip groove 11 is provided on the side surface of part No. 1 and the other side surface of part No. 2 near the lower end. Limit strips 12 are integrally formed on both sides of the elastic strip 10. The limit strips 12 are inserted into the strip groove 11. Several groups of bolt holes 13 are provided on the upper end surface of the elastic strip 10 at equal intervals.

[0072] The limiting strip 12 is inserted into the strip groove 11 . After the limiting strip 12 and the strip groove 11 are inserted, they are fixed by friction and will not become loose in normal use.

[0073] The first part, the second part and the middle elastic part adopt a split design, which can facilitate the installation of the slider 3 during installation.

[0074] When in use, install the bolt into the bolt hole 13 on the elastic strip 10. When in use, tighten the bolt, and the bolt moves downward, which will squeeze the upper end surface of the elastic strip 10, causing the elastic strip 10 to deform, which will push the No. 1 part and the No. 2 part to move sideways, thereby changing the distance between the No. 1 part and the No. 2 part.

[0075] There are multiple groups of bolt holes 13. When part No. 1 and part No. 2 are locally deformed, the mounting bolts in the bolt holes 13 on the elastic strip 10 corresponding to the positions where part No. 1 and part No. 2 are deformed can be turned and adjusted appropriately. This can fine-tune the supporting strength of the middle elastic part on part No. 1 and part No. 2, thereby achieving an improved effect.

[0076] Example 3:

[0077] On the basis of Example 2, Figures 1-9 As shown, this embodiment shows the structure of the limit strip 12;

[0078] like Figure 9 As shown, the shape of the limiting strip 12 is various. Figure 9 The structure of the first limiting strip 12 is the most common and commonly used structure. When in use, the limiting strip 12 can be directly inserted sideways into the strip groove 11;

[0079] like Figure 9 As shown, using Figure 9 The second limiting strip 12 can be directly inserted into the strip groove 11 sideways when in use. The area of ​​the end surface is relatively small, so it is more convenient to insert when in use than the first structure.

[0080] like Figure 9 As shown, using Figure 9The structure of the third limit strip 12. When this structure is adopted, the strip groove 11 is set corresponding to the structure of the limit strip 12. When in use, the limit strip 12 must be inserted into the strip groove 11 from the end. After insertion, the limit strip 12 is restricted, and the No. 1 part, the middle elastic part and the No. 2 part are combined to form a whole, and will not be easily separated when subjected to force.

[0081] like Figure 9 As shown, using Figure 9 The structure of the fourth limit strip 12, when adopting this structure, the strip groove 11 is set corresponding to the structure of the limit strip 12, and the limit strip 12 must be inserted into the strip groove 11 from the end when in use. After insertion, the limit strip 12 is restricted, and the No. 1 part, the middle elastic part and the No. 2 part are combined to form a whole, which will not be easily separated when subjected to force. Compared with the third structure, it has a wider contact area and a better connection effect.

[0082] Example 4:

[0083] On the basis of Example 3, Figures 1-8 As shown, this embodiment shows the partial structure of the first and second parts;

[0084] A limit blocking strip is integrally formed on the side surface of the No. 1 portion and the other side surface of the No. 2 portion, and the limit blocking strip is located above the slider 3 .

[0085] The setting of the limit blocking strip can apply force from above, limit the position of the slider 3, and effectively prevent the elevator door from detaching from the slide 2. The limit blocking strip can achieve a long-term positioning effect, has a relatively long service life, and has a good use effect.

[0086] The slide 2 is supported from the side. When in use, although the upper and lower ends of the slider 3 do not contact the lower end surface of the limit blocking strip and the upper end surface of the middle elastic part, the connecting plate 4 will contact the limit blocking strip after the elevator door is slightly deformed by force. At this time, the limit blocking strip plays a supporting and limiting role, which can prevent the slider 3 from detaching from the slide 2. The supporting effect can reduce the deformation of the elevator door, extend the service life of the elevator door, and have a good use effect.

[0087] The end surface of the limit blocking strip facing the middle elastic part is arc-shaped, and the limit blocking strip can reduce contact with the connecting plate 4, thereby making the elevator door move more smoothly, and no noise is generated during movement, with good use effect.

[0088] A plurality of groups of arc-shaped protrusions 15 are fixedly mounted on the outer surface of the slider 3 , and the protrusions 15 fit in contact with the inner side wall of the slideway 2 .

[0089] The protrusion 15 is hemispherical in shape. When it fits with the inner wall of the slide 2, the fitting point is a point, and the fitting area is very small, which can reduce friction and make the movement of the slider 3 smoother.

[0090] The present invention records a lightweight and high-strength sill, on which a limit blocking strip is integrally formed on the side of the No. 1 part and the other side of the No. 2 part. The limit blocking strip is located above the slider 3. The use of the limit blocking strip further above the slider 3 can provide a better supporting effect, and can effectively prevent the slider 3 from being separated from the slide 2 when the door is deformed due to impact. It has good use effect and has good prospects for use.

[0091] Example 5:

[0092] On the basis of Example 4, Figures 1-8 As shown, this embodiment is the structure of the second part;

[0093] A cavity 5 for storing miscellaneous items is provided inside the No. 2 part, and a plurality of groups of openings 6 are provided on the other side of the No. 2 part. The plurality of groups of openings 6 are arranged at equal intervals, and the cavities 5 are connected to each other through the openings 6 .

[0094] Like ordinary elevator sills, due to the limited width of slide 2 and the thick elevator door, the lower end of the elevator door will completely block the slide 2. Therefore, normal washing cannot clean out the debris in the slide 2. After long-term use, a large amount of debris will accumulate in the slide 2, and these debris are difficult to clean, which may easily cause the elevator door to jam.

[0095] When there is a hard object inside the slideway 2, if the existing elevator sill is used, the slider 3 will be subjected to force when it contacts the hard object, and it will shake violently. Over time, the slider 3 is likely to derail or deform.

[0096] The structure recorded in this patent is different. In this patent, during the operation of the slider 3, the push block 7 will come into contact with the debris first. If it encounters a hard object, it can directly shovel the hard object off. Through the cooperation of the guide block 8 and the push block 7, the hard object shoveled off can be quickly guided into the interior of the cavity 5, thereby reducing the contact between the hard object and the slider 3, thereby improving the stability of the operation of the slider 3, thereby extending the service life of the slider 3, and greatly reducing the failure rate of the elevator door operation.

[0097] During use, debris in the slide 2 will move through the opening 6 into the cavity 5 , thereby reducing the amount of debris in the slide 2 .

[0098] The cavity 5 can accommodate a certain amount of debris, thereby reducing the impact of the debris on the movement of the slider 3 .

[0099] The front end face and the rear end face of the slider 3 are both provided with push blocks 7 , and the push blocks 7 are tilted away from the end face of the slider 3 .

[0100] The push block 7 is tilted and can shovel debris in the slide 2 so that the debris is separated from the inner wall of the slide 2. At the same time, its tilted surface can guide the movement of the debris so that the debris moves into the interior of the cavity 5.

[0101] A guide block 8 is fixedly installed on the other side of the No. 2 part. The outer surface of the guide block 8 is set at an angle. The number of guide blocks 8 is several groups, and the several groups of guide blocks 8 are arranged at equal intervals on the other side of the No. 2 part.

[0102] The guide block 8 and the push block 7 cooperate with each other. The combination of the two can enable most of the debris to pass through the opening 6 and fall into the interior of the cavity 5, thereby effectively reducing the debris in the slide 2 and making the movement of the slider 3 more stable and smooth.

[0103] A through opening 9 is provided on the upper end surface of the second portion near the front end, and the lower end of the through opening 9 is communicated with the interior of the cavity 5 .

[0104] When in use, a rubber plug can be installed at the through port 9, which can be opened when cleaning and closed when not cleaning, thereby effectively preventing debris from falling into the interior of the cavity 5 and achieving good use effect.

[0105] The provision of the through-port 9 can facilitate its connection with the dust collection device, and the sundries stored inside the cavity 5 can be directly extracted through the through-port 9 to achieve a cleaning effect.

[0106] For example, an existing vacuum cleaner can be used, and the pipe of the vacuum cleaner can be aligned with the opening 9. The suction force generated by the vacuum cleaner can extract the debris, and the use effect is good.

[0107] The present invention records a lightweight, high-strength sill, which records a cavity 5, and the cavity 5 is connected to the slide 2, and a push block 7 is provided on the slider 3. This setting enables the slider 3 to scrape off most of the debris and push it into the cavity 5 during operation. Combined with the setting of the opening 9, it can extract the debris, thereby effectively avoiding the interference of the debris on the operation of the elevator door, improving the smoothness of the use of the elevator door, and has good use prospects.

[0108] The other side surface of the No. 1 portion and the side surface of the No. 2 portion are both integrally formed with a reinforcement strip 14 , which is bent away from the middle elastic portion.

[0109] The reinforcing strip 14 is made of high-strength material and mainly plays a supporting role. The setting of the reinforcing strip 14 can effectively increase the strength and reduce the deformation of the elevator sill during use.

[0110] The bent portion of the reinforcing strip 14 fits with the concrete or other materials, and the concrete or other materials provide an outward force, which can prevent the No. 1 and No. 2 parts from excessively squeezing the middle elastic part, thereby effectively extending the service life of the middle elastic part.

[0111] For example, the reinforcing strip 14 can be made of alloy material or carbon fiber material. When carbon fiber material is used, it is thinner and lighter, and the overall weight is also lighter, which can be convenient for workers to carry, has a longer service life, and has a good use effect.

[0112] There are multiple groups of reinforcing strips 14, which can effectively increase the strength of the sill. The reinforcing strips 14 are bent to limit the positions of the No. 1 and No. 2 parts, avoiding excessive squeezing of the middle elastic part when it is deformed under force.

[0113] It should be noted that the present invention is a light and thin high strength sill. When in use, the sill is installed as follows Figure 8 When the slider 3 is in motion, the protrusion 15 just contacts the side wall of the slide 2, and the door will not be opened or closed smoothly, and there will be a loud noise. Then, the connecting plate 4 can be installed. No new parts need to be replaced during the whole process. The maintenance time is relatively short, the overall cost is relatively low, and the use effect is good.
