Description

Technical Field

[0001] The utility model relates to the technical field of profiles, in particular to an elevator car column profile. Background Art

[0002] As a means of transportation, elevators have become an indispensable part of high-rise buildings and public spaces. As living standards improve, so too do people's expectations for elevators. They demand not only stylish and aesthetically pleasing walls but also a host of new features, such as impact resistance, vibration reduction, and noise reduction. Elevator cars typically consist of columns and crossbeams, with the crossbeams connecting two adjacent columns. Existing car wall structures are typically constructed of bent steel plates or stainless steel. These require numerous fasteners to secure the walls to the columns, making installation cumbersome, time-consuming, and labor-intensive.

[0003] In order to solve the above problems, in the prior art, such as the patent document with application number CN202323473723.7, a mounting profile for the large column of the elevator car is disclosed. By setting a mounting profile with a special structure, it is convenient for installation and subsequent maintenance. If the car wall needs to be replaced, the rear column buckle plate can be directly removed without removing the car roof; at the same time, the entire column mounting structure has good stress effect and stable structure.

[0004] However, the technical solutions provided in the above patent documents still have limitations when they are implemented, as follows:

[0005] First, although the profiles provided in the above patent document can be used for the assembly of the car (specifically used as columns, please refer to the patent document with application number CN202220584430.2, which discloses an elevator car with an aluminum profile structure, the location of the profiles can be referred to the attached drawings of the specification of the patent document. Figure 1 However, when facing high-rise and heavy-duty cars, because high-rise and heavy-duty cars require heavy loads, the profiles provided in the above patent documents, although reduced in weight by a larger internal cavity, are insufficient in strength. Once the length of the car design is long, under a heavy load, the profiles are prone to deformation (especially when used as columns, the strength of the middle area of ​​the longer columns may not meet the requirements, so the probability of deformation increases);

[0006] Secondly, the internal cavity of the profile is large, resulting in insufficient overall space utilization.

[0007] Finally, the profile structure provided in the above patent document has a relatively simple function. When in use (in the car, the side facing people is the door opening area, and this side for entering requires a movable door leaf. The back side after entering does not require it), it is necessary to design whether to install a movable door leaf.

[0008] Therefore, how to solve the above-mentioned deficiencies existing in the prior art has become the subject to be studied and solved by the utility model. Utility model content

[0022] The first rectangle has four corners, wherein the second corner is a corner of the first rectangle, and a first bent plate is provided at a corner of the first rectangle opposite to the second corner;

[0023] One end of the first bent plate is connected to the first horizontal auxiliary plate, and the other end is connected to the first vertical auxiliary plate;

[0024] The first bent plate, the first horizontal auxiliary plate, and the first vertical auxiliary plate define a first square cavity within the first rectangle;

[0028] The second horizontal auxiliary plate, the second vertical auxiliary plate, the first horizontal auxiliary plate and the second vertical plate define a second rectangle;

[0034] The profile body further includes a notch portion and a step portion;

[0035] The notch is provided on a side surface of the second horizontal auxiliary plate away from the second vertical auxiliary plate, and is located at an end of the second horizontal auxiliary plate away from the second vertical plate;

[0036] The step portion is provided at an end portion of the frame structure corresponding to the first rectangle.

[0037] The relevant contents of the above plan are explained as follows:

[0038] In the above scheme, the arc plate and the second connecting plate are formed as one piece. At the same time, the opening on the arc plate is set so that the side wall of the circular structure formed by the arc plate and the second corner has an opening. Without affecting the design function, it is beneficial to the design and processing of the mold and reduces the production difficulty. Functionally speaking, this is used to insert pins for connecting profiles, which plays a positioning role and facilitates installation.

[0039] In the above scheme, the design of the "L"-shaped closed cavity and other cavities is to reduce the weight of the profile itself. While ensuring sufficient bearing capacity, the weight of the profile is reduced as much as possible, reducing the overall weight and saving costs.

[0040] In the above scheme, the two bent plates and the two notches are designed to carry and fix fasteners. The fasteners are used to connect the two profile bodies. Because when longer columns are required, the two profile bodies need to be connected, so fasteners are needed. Fasteners usually use connecting components such as connecting plates and pins.

[0041] In the above solution, the notch portion can be used to fix the wire pressing profile by a snap connection; the step portion can be used to fix the adapter profile by a screw fixation;

[0042] The function of the press-line profile and the transfer profile is to fix the insulating glass, but the scenarios when they are used are different, because when in use, the side facing people in the car is the door opening area, and this side needs to have a movable door leaf. That is to say, at this time, the main body of the profile is used as a column, and only the notch part is used to install the insulating glass. The back side after entering is not needed, so the main body of the profile is used as a corner, and both the notch part and the step part need to be installed with insulating glass.

[0043] The reinforcing plate can increase the stability of product production, and can also increase the strength and reliability of the profile body.

[0044] Further, the first transverse auxiliary plate is provided with a selective thickening part at a position corresponding to the first notch.

[0045] The second vertical auxiliary plate is also provided with a selective thickening part at a position corresponding to the second notch.

[0046] The selective thickening part is provided to provide sufficient strength support to the profile body (mainly the first notch and the second notch) when the fastener is subjected to vertical and transverse stress.

[0047] Further, the notch part includes a first hook and a second hook provided on the same side surface of the second transverse auxiliary plate, the first hook is provided apart from the second hook, and both are located at an end of the second transverse auxiliary plate away from the second longitudinal plate.

[0048] The first hook is provided with a first hook part protruding from one side of the first hook toward the second hook.

[0049] The second hook is provided with a second hook part protruding from one side of the second hook toward the first hook.

[0050] With the above design, the notch part can be quickly clamped and fixed with the wire pressing profile.

[0051] Further, the step part is a protruding block provided at an end of the first transverse plate and extending away from the first longitudinal plate.

[0052] The design of the protruding block facilitates the installation of the adapter profile and increases safety.

[0053] Further, the fastener includes a first component connecting plate, a pin column, and a second component connecting plate.

[0054] The first component connecting plate is provided in the second square cavity.

[0055] The pin column is located in the second square cavity, and the pin column is provided on the first component connecting plate, the pin column passes through the second notch, and the second component connecting plate is connected with the profile body through the passing end of the pin column.

[0056] When two profile bodies are spliced ​​into one, a connecting assembly is needed to splice the two profile bodies. Under normal circumstances, if the connecting piece is directly attached to the connection between the two profile bodies and a pin is passed through, preliminary fixation can be achieved. However, this will cause a problem, that is, gaps are easily generated when the two profile bodies are connected. The reason is that when the two profile bodies are connected up and down, once shaking occurs, the two connecting surfaces are easily offset and misaligned.

[0057] By means of the above-mentioned design of providing two bent plates and two notches, and the two bent plates and two notches being respectively located in the length direction and width direction of the profile body, the calibration problem during splicing is solved.

[0058] The selective thickening portion is provided so that the main body of the profile (mainly at the first notch) can have sufficient strength support when the fastener generates vertical and horizontal forces.

[0059] According to a further technical solution, both the first corner and the second corner are arc-shaped and are concentrically arranged.

[0060] With the aid of the above design, the difficulty of forming the frame structure is further reduced.

[0061] According to a further technical solution, a surface of the first longitudinal plate has a groove, the groove is arranged toward the inner side of the closed cavity and is integrally connected to the reinforcing plate.

[0062] The groove design can increase the aesthetics and overall three-dimensionality; secondly, if the temperature difference between the inside and outside causes water mist, the water vapor can be separated and gathered here, which is conducive to cleaning.

[0063] According to a further technical solution, the turning angles of the first bending plate and the second bending plate are both 90 degrees.

[0064] With the above design, when the fastener is installed in the first square cavity and / or the second square cavity, the first component connecting plate can fully fit the inner wall of the first square cavity and / or the second square cavity.

[0065] The terms “first”, “second”, etc. used in this document do not specifically refer to an order or sequence, nor are they used to limit this case. They are only used to distinguish components or operations described with the same technical terms.

[0066] As used herein, “connected” or “positioned” may refer to two or more components or devices being in direct or indirect physical contact with each other, or may refer to two or more components or devices operating or moving with each other.

[0067] The terms “include”, “including”, “have”, etc. used in this document are open-ended terms, meaning including but not limited to.

[0068] As to the terms used herein, generally, each term has the ordinary meaning used in the art, in the context of the present case and in the special context, unless otherwise specifically indicated. Some terms used to describe the present case will be discussed below or elsewhere in the specification to provide additional guidance to those skilled in the art on the relevant description of the present case.

[0069] As to the terms "front", "back", "up", "down", "left", "right" and the like used herein, they are all directional terms, which are only used to illustrate the positional relationship between structures in the present case, and are not used to limit the specific direction of the protection scheme and actual implementation of the present case.

[0070] The working principle and advantages of the present utility model are as follows:

[0071] In the present utility model, the design of the "L" shaped closed cavity and other cavities is to reduce the weight of the profile itself. Under the condition of ensuring sufficient bearing capacity, the profile weight is reduced as much as possible, the overall weight is reduced, and the cost is saved.

[0072] In the present utility model, the cooperation of the two bending plates and the two notches is used to bear and fix the fastener, and the fastener is used to connect the two profile main bodies. Because the longer stand is needed when it is used, the two profile main bodies need to be connected, so the fastener is needed, and the fastener usually adopts connecting components such as connecting sheets and pins. Secondly, the notch part can be used to fix the pressed wire profile, and the fixing mode is buckle connection; the step part can be used to fix the adapter profile, and the fixing mode is screw fixing; the functions of the pressed wire profile and the adapter profile are to fix the hollow glass, but the scenes are different when they are used. Because in the use, the side facing the people in the car is the door opening area, and the face after entering needs to have a movable door leaf, that is, at this time, the profile main body is used as a stand, and only the notch part is used to install the hollow glass at this time, and the back after entering is not needed, so the profile main body is used as a corner at this time, and the notch part and the step part both need to install the hollow glass, so it can be shown that the profile main body in the present utility model has diversified functions and does not need to be designed separately for different use cases.

[0073] In the present utility model, the setting of the reinforcing plate can increase the stability of product production, and secondly, it can also increase the strength and reliability of the profile main body.

[0074] In the present utility model, the first bending plate and the second bending plate capable of cooperating with the fastener are arranged in the first rectangle and the second rectangle respectively, which greatly improves the equipment utilization. BRIEF DESCRIPTION OF DRAWINGS

[0112] In the present invention, the design of the "L"-shaped closed cavity and other cavities is to reduce the weight of the profile itself. While ensuring sufficient bearing capacity, the weight of the profile is reduced as much as possible, the overall weight is reduced, and the cost is saved.

[0113] In the present invention, the two bent plates and the two notches are used to carry and fix fasteners, and the fasteners are used to connect the two profile bodies 1. Because when a longer column is required, the two profile bodies 1 need to be connected, so fasteners are needed. The fasteners usually use connecting components such as connecting plates and pins.

[0114] In the present invention, the notch portion 17 can be used to fix the wire pressing profile, and the fixing method is a snap connection; the step portion 18 can be used to fix the adapter profile, and the fixing method is screw fixing;

[0115] The function of the pressing profile and the transfer profile is to fix the insulating glass, but the scenarios when they are used are different, because when in use, the side facing people in the car is the door opening area, and the side entering requires a movable door leaf, that is to say, at this time, the profile body 1 is used as a column, and only the notch portion 17 is used to install the insulating glass. The back side after entering is not needed, so the profile body 1 is used as a corner at this time, and both the notch portion 17 and the step portion 18 need to be installed with insulating glass.

[0118] When a longer profile body 1 is required, two profile bodies 1 need to be spliced ​​together, and the profile body 1 can be limited and fixed in the width direction by means of the first notch 21 on the first rectangle 35, the first bent plate 19 and the cooperation with the fastener.

[0119] By means of the second notch 34 on the second rectangle 36 , the second bent plate 27 and the cooperation with the fastener, the profile body 1 can be limited and fixed in the length direction.

[0120] It should be noted that the length and width of the profile body 1 are defined from the perspective of the cross section. Figure 1 、 Figure 3 、 Figure 4 and Figure 5 .

[0121] A selective thickening portion 22 is provided at a position corresponding to the first notch 21 on the first horizontal auxiliary plate 13;

[0122] The second vertical auxiliary plate 16 is also provided with a selective thickening portion 22 at the position corresponding to the second notch 34. The selective thickening portion 22 is provided to ensure that the profile body 1 (mainly the first notch 21 and the second notch 34) has sufficient strength to support the fastener when the fastener generates vertical and horizontal forces.

[0123] like Figures 1-5 As shown, in order to enable the notch portion 17 to be quickly engaged and fixed with the wire pressing profile, the notch portion 17 includes a first hook 23 and a second hook 24 provided on the same side surface of the second horizontal auxiliary plate 15. The first hook 23 and the second hook 24 are spaced apart and are both located at the end of the second horizontal auxiliary plate 15 away from the second longitudinal plate 4.

[0124] A first hook portion 25 is protruded from one side of the first hook 23 toward the second hook 24;

[0125] The second hook 24 is provided with a second hook portion 26 on one side thereof protruding toward the first hook 23. Specifically, when the notch portion 17 needs to fix the wire pressing profile, the wire pressing profile is directly guided to be pressed between the first hook 23 and the second hook 24. When the wire pressing profile contacts the first hook 23 and the second hook 24, the first hook portion 25 and the second hook portion 26 will simultaneously buckle the wire pressing profile to complete the purpose of fixing the wire pressing profile.

[0126] like Figure 1 、 Figure 3 、 Figure 4 and Figure 5 As shown, the step portion 18 is a protrusion 30 provided at the end of the first transverse plate 3 and extending toward the side away from the first longitudinal plate 2. The design of the protrusion 30 facilitates the installation of the transition profile and increases safety. When the transition profile needs to be fixed, the transition profile is first overlapped on the protrusion 30, thereby achieving pre-positioning through the protrusion 30, and then the transition profile is fixedly connected to the profile body 1 by a pin (for example, refer to Figure 3 The fastener structure in the embodiment can be connected with two fasteners).

[0127] In some embodiments, the fastener includes a first component connecting plate 31, a pin column 32, and a second component connecting plate 33;

[0128] The first component connecting plate 31 is disposed in the second square chamber 28;

[0129] The pin column 32 is located within the second square cavity 28 and is inserted through the first component connecting plate 31. The protruding end of the pin column 32 passes through the second notch 34. The second component connecting plate 33 is connected to the profile body 1 via the protruding end of the pin column 32. The fastener can be a connecting member such as a pin that connects two objects. The following provides a preferred embodiment of the fastener for this application:

[0130] When two profile bodies 1 are spliced ​​into one, a connecting assembly is required to splice the two profile bodies 1. Under normal circumstances, if the connecting piece is directly attached to the connection between the two profile bodies 1 and a pin is passed through, preliminary fixation can be achieved. However, this will cause a problem, that is, a gap is easily generated when the two profile bodies 1 are connected. The reason is that when the two profile bodies 1 are connected up and down, once shaking occurs, the two connecting surfaces are easily offset and misaligned.

[0131] By means of the above-mentioned design of two bent plates and two notches, and the two bent plates and two notches being respectively located in the length direction and width direction of the profile body 1, the calibration problem during splicing can be solved.

[0132] Specifically, when the profile body 1 is fixedly connected in the length direction and the width direction and the limit calibration is performed (refer to Figure 3 The following is an example from the longitudinal direction of the profile body 1, because the fixing method in the width direction is the same and is not drawn in the drawings of the specification).

[0133] The first component connecting plate 31 is directly clamped into the first square cavity 20. At this time, the upper end of the first component connecting plate 31 abuts against the surface of the second horizontal auxiliary plate 15, and the lower end abuts against the second bending plate 27 (that is, the width of the first component connecting plate 31 is equal to the width of the second square cavity 28).

[0134] Before the first component connecting plate 31 is snapped into the first square chamber 20, the pin column 32 is inserted into the first component connecting plate 31. After the first component connecting plate 31 is snapped into the first square chamber 20, the protruding end of the pin column 32 will pass through the second notch 34. Subsequently, the second component connecting plate 33 is connected to the profile body 1 through the protruding end of the pin column 32, thereby realizing the fixed connection and limit calibration of the profile body 1 in the length direction.

[0135] In some specific embodiments, the first corner 7 and the second corner 8 are both arc-shaped and are arranged concentrically. With the above design, the difficulty of forming the frame structure 12 is further reduced.

[0136] In some embodiments, the surface of the first longitudinal plate 2 has a groove 29, which faces the inside of the enclosed cavity and is integrally connected to a reinforcing plate 6. The design of the groove 29 enhances the aesthetics and overall three-dimensionality of the structure. Furthermore, if a temperature difference between inside and outside causes mist, the mist can be isolated and collected here, facilitating cleaning.

[0137] In some specific embodiments, the turning angles of the first bent plate 19 and the second bent plate 27 are both 90 degrees.

[0138] With the above design, when the fastener is installed in the first square cavity 20 and / or the second square cavity 28, the first component connecting plate 31 can fully fit the inner wall of the first square cavity 20 and / or the second square cavity 28.

[0139] Working principle:

[0140] From the perspective of a single profile body 1, the notch portion 17 can be used to fix the wire-pressing profile by a snap connection; the step portion 18 can be used to fix the adapter profile by screw fixation; this can expand the scope of use of the profile body 1 and provide the profile body 1 with more functions.

[0141] The function of the pressing profile and the transfer profile is to fix the insulating glass, but the scenarios when they are used are different, because when in use, the side facing people in the car is the door opening area, and the side entering requires a movable door leaf, that is to say, at this time, the profile body 1 is used as a column, and only the notch portion 17 is used to install the insulating glass. The back side after entering is not needed, so the profile body 1 is used as a corner at this time, and both the notch portion 17 and the step portion 18 need to be installed with insulating glass.

[0142] Specifically, when the notch portion 17 needs to fix the wire-pressing profile, the wire-pressing profile is directly guided to be pressed between the first hook 23 and the second hook 24. When the wire-pressing profile contacts the first hook 23 and the second hook 24, the first hook portion 25 and the second hook portion 26 will simultaneously buckle the wire-pressing profile to achieve the purpose of fixing the wire-pressing profile.

[0143] When the transition profile needs to be fixed, the transition profile is first overlapped on the protruding block 30, so that the protruding block 30 is pre-positioned, and then the transition profile is fixedly connected to the profile body 1 by a pin (for example, refer to Figure 3 The fastener structure in the embodiment can be connected with two fasteners).

[0144] Secondly, when the car requires a longer column, the two profile bodies 1 need to be butt-jointed up and down.

[0145] Specifically, when the profile body 1 is fixedly connected in the length direction and the width direction and the limit calibration is performed (refer to Figure 3 An example is given from the longitudinal direction of the profile body 1. Since the fixing method in the width direction is the same and is not drawn in the drawings of the specification, no detailed description will be given).

[0146] The first component connecting plate 31 is directly clamped into the first square cavity 20. At this time, the upper end of the first component connecting plate 31 abuts against the surface of the second horizontal auxiliary plate 15, and the lower end abuts against the second bending plate 27 (that is, the width of the first component connecting plate 31 is equal to the width of the second square cavity 28).

[0147] Before the first component connecting plate 31 is snapped into the first square chamber 20, the pin column 32 is inserted into the first component connecting plate 31. After the first component connecting plate 31 is snapped into the first square chamber 20, the protruding end of the pin column 32 will pass through the second notch 34. Subsequently, the second component connecting plate 33 is connected to the profile body 1 through the protruding end of the pin column 32, thereby realizing the fixed connection and limit calibration of the profile body 1 in the length direction.

Their purpose is to enable those familiar with the art to understand the contents of the present invention and implement them accordingly. They are not intended to limit the scope of protection of the present invention. Any equivalent changes or modifications based on the spirit of the present invention are intended to be included in the scope of protection of the present invention.
