Description

Technical Field

[0001] This utility model belongs to the technical field of elevator door frame installation, and in particular relates to an elevator door frame structure and an elevator. Background Technology

[0002] The elevator door frame is installed at the elevator entrance on each floor. It includes a small door frame and a large door frame. The small door frame is used to fix the elevator door and is installed at the door opening. The installation of the small door frame is completed during the elevator installation. The large door frame covers the part of the wall between the small door frame and the outer edge of the wall. It is used to cover part of the gap between the small door frame and the door opening. It is installed after the elevator installation is completed.

[0003] Currently, traditional elevator door frames are typically installed and fixed to the elevator shaft wall. There are two main types of door frames: the first uses stone or wall tiles; the second uses decorative wood. However, door frames installed with stone or wall tiles have a long construction period and are easily affected by the adhesive materials and the skill of the installer, often posing a safety hazard of falling off. Door frames using decorative wood are complex to install, require painting for corrosion protection afterward, and are prone to rotting, necessitating frequent inspection and maintenance. Utility Model Content

[0004] Therefore, it is necessary to provide an elevator door frame structure and elevator that are easy to install.

[0005] An elevator door frame structure, comprising:

[0006] Small door frame;

[0007] Door frame;

[0008] The connecting component includes a clip, a snap-fit ​​plate, and a connector. The clip and the snap-fit ​​plate can be fixed to the small door frame by the connector, so that a slot is formed between the clip and the snap-fit ​​plate, and the slot can be inserted into the large door frame.

[0009] The snap-fit ​​plate has a snap hook, which is disposed in the slot and can engage with the door frame inserted into the slot to lock the door frame and fix the door frame to the small door frame.

[0010] Understandably, the main door frame is fixed to the connecting component of the smaller door frame using a snap-fit ​​method, allowing the main door frame to be installed using the smaller door frame as the installation base. This facilitates the installation of the main door frame, significantly improves the construction efficiency during installation, shortens the construction cycle, and reduces costs.

[0011] In one embodiment, a bent plate is formed on the card strip, which can abut against the door frame inserted into the slot to limit the door frame to the card plate and engage the door frame with the card hook.

[0012] Understandably, the door frame is limited to the snap-fit ​​plate by the bending plate on the snap-fit ​​strip, so that the snap-fit ​​strip can prevent the door frame from detaching from the snap-fit ​​plate, thus ensuring the stability of the door frame installation.

[0013] In one embodiment, the door frame is partially bent and has barbs, and the door frame can engage with the hooks via the barbs.

[0014] In one embodiment, the number of hooks is configured as multiple rows, and the multiple rows of hooks are arranged at intervals along the depth direction of the slot;

[0015] The barbs can engage with multiple rows of hooks respectively.

[0016] Understandably, because the barbs on the door frame can engage with multiple rows of hooks, the door frame can be locked multiple times during the insertion and assembly process in the slot. This allows users to achieve assembly by repeatedly tapping the door frame, which further facilitates the installation of the door frame.

[0017] In one embodiment, the main door frame is bent to form a U-shaped bend, which is located on the outside of the small door frame and is used to abut against the exterior of the elevator shaft to limit the insertion depth of the main door frame in the slot.

[0018] It is understandable that the U-shaped bend on the door frame and its contact with the exterior of the elevator shaft are used to limit the assembly of the door frame onto the smaller door frame, thus serving as a reminder to ensure the door frame is properly assembled.

[0019] In one embodiment, the card strip has a first bent edge, the card plate has a second bent edge, and the second bent edge abuts against the first bent edge;

[0020] The connector is configured as a self-tapping screw, which passes through the first bent edge and the second bent edge and is screwed to the small door frame.

[0021] It is understandable that the self-tapping screws are used to simultaneously pass through the first bent edge on the clip and the second bent edge on the snap-fit ​​plate and then screw them into the small door frame to achieve the assembly and fixation of the clip and snap-fit ​​plate on the small door frame. This makes it easier to fix the connecting component to the small door frame.

[0022] In one embodiment, the door frame includes an upper door frame and two side door frames, the upper door frame being disposed between the two side door frames and being inserted into each of the two side door frames respectively.

[0023] Understandably, the two side door frames are connected to the upper door frame by a plug-in joint, which allows the door frame to be assembled on-site, thus facilitating the assembly of the door frame.

[0024] In one embodiment, a plug-in piece is connected to the side wall of the upper door frame, one end of the plug-in piece connected to the side wall forms a connecting end, and the end of the plug-in piece away from the side wall is configured as a movable end.

[0025] When the upper door frame is inserted into the side door frame, the movable end passes through the side door frame and is subjected to a force, causing the movable end to deform and form a perpendicular structure with the connecting end, thereby locking the upper door frame onto the side door frame.

[0026] It is understandable that by utilizing the deformation of the movable end of the upper door frame's insert plate under external forces such as torsional force, upward folding force, or downward folding force, and forming a perpendicular structure with the connecting end, the locking between the upper door frame and the side door frame can be achieved. This facilitates the locking between the upper door frame and the side door frame, making operation simple; on the other hand, it also improves the structural stability when the upper door frame and the side door frame are locked, and enhances the structural strength of the connection between the upper door frame and the side door frame.

[0027] In one embodiment, the upper door frame and the two side door frames are respectively connected to the small door frame by a plurality of the connecting components.

[0028] Understandably, using multiple connecting components to connect and fix the upper door frame and the two side door frames to the smaller door frame can improve the stability of the installation of the main door frame on the smaller door frame.

[0029] This application also claims protection for an elevator, including the elevator door frame structure described above.

[0030] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art:

[0031] The elevator door frame structure and elevator claimed in this application are provided. The large door frame is fixed to the connecting component connected to the small door frame by a snap-fit ​​method, so that the large door frame can be installed on the basis of the small door frame. This facilitates the installation of the large door frame, greatly improves the construction efficiency during the installation of the large door frame, shortens the construction period, and reduces costs.

[0041] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0042] like Figures 1 to 4 As shown, the elevator door frame structure 100 provided in this application includes a small door frame 10, a large door frame 20, and a connecting assembly 30. The connecting assembly 30 includes a locking strip 31, a locking plate 32, and a connector 33. The locking strip 31 and the locking plate 32 can be fixed to the small door frame 10 through the connector 33, so that a slot 301 is formed between the locking strip 31 and the locking plate 32. The slot 301 can be inserted and engaged with the large door frame 20. The locking plate 32 has a hook 321, which is disposed in the slot 301 and can engage with the large door frame 20 inserted into the slot 301 to lock the large door frame 20 and fix the large door frame 20 to the small door frame 10. In other words, the large door frame 20 can be fixed to the small door frame 10 through the connecting assembly 30.

[0043] As can be seen from the above, the main door frame 20 of this application is fixed to the connecting component 30 connected to the small door frame 10 by a snap-fit ​​method, so that the main door frame 20 can be installed on the small door frame 10 as the installation base. This facilitates the installation of the main door frame 20, and has the effect of greatly improving the construction efficiency of the installation of the main door frame 20, shortening the construction cycle, and reducing costs.

[0044] In one embodiment, the door frame 20 is made of black titanium stainless steel, which makes the overall appearance of the door frame 20 simple and elegant.

[0045] like Figure 5 As shown, in one embodiment, the main door frame 20 includes an upper door frame 21 and two side door frames 22. The upper door frame 21 is disposed between the two side door frames 22 and is inserted into each of the two side door frames 22, allowing the main door frame 20 to be assembled on-site, thus facilitating its assembly. It should be noted that in this embodiment, the upper door frame 21 can be first inserted and fixed to one of the side door frames 22, and then inserted and fixed to the other side door frame 22, forming the main door frame 20 into a single integral structure. It is understood that in other embodiments, the upper door frame 21 can also be connected and fixed to the two side door frames 22 by welding or adhesive bonding, which will not be elaborated upon here.

[0046] like Figure 5As shown, in this embodiment, a connector 212 is connected to the side wall 211 of the upper door frame 21. One end of the connector 212 connected to the side wall 211 forms a connecting end, and the other end of the connector 212 away from the side wall 211 is configured as a movable end 2121. When the upper door frame 21 is inserted into the side door frame 22, the movable end 2121 is subjected to forces such as torsional force, upward or downward folding force after passing through the side door frame 22, so that the movable end 2121 deforms and forms a non-plane perpendicular structure with the connecting end, such as forming a <-shaped, L-shaped or large-angle (greater than 90 degrees) L-shaped non-plane perpendicular structure; and locks the upper door frame 21 onto the side door frame 22. This facilitates locking between the upper door frame 21 and the side door frame 22, making operation simple; on the other hand, it also improves the structural stability when the upper door frame 21 and the side door frame 22 are locked, and improves the structural strength of the connection between the upper door frame 21 and the side door frame 22. Here, the upper door frame 21 and the side door frame 22 can be locked together by multiple plug-in pieces 212. The movable end 2121 of the plug-in piece 212 can be operated manually or by using tools, such as using pliers to twist the movable end 2121 of the plug-in piece 212 that passes through the side door frame 22.

[0047] like Figure 3 , Figure 4 As shown, in one embodiment, the upper door frame 21 and the two side door frames 22 can be formed by bending stainless steel single plates. One end of the stainless steel single plate is bent to form a barb 201, which serves to fix and adjust the distance between the door frame 20 and the slot 301. The other end of the stainless steel single plate is bent to form a U-shaped bend 202, which enhances the overall rigidity and stability of the door frame 20.

[0048] like Figures 2 to 4 As shown, in this embodiment, the door frame 20 can be inserted into the slot 301 using a barb 201, and can be engaged with the hook 321 on the snap-fit ​​plate 32 through the barb 201, thereby achieving the snap-fit ​​between the door frame 20 and the hook 321 on the snap-fit ​​plate 32. During this process, the U-shaped bend 202 of the door frame 20 is provided on the outside of the small door frame 10, so that when the door frame 20 is inserted into the slot 301, the U-shaped bend 202 can be close to the outer facade 200 of the elevator shaft, thereby limiting the insertion depth of the door frame 20 in the slot 301, and serving as a reminder that the door frame 20 is properly assembled.

[0049] In this embodiment, the upper door frame 21 and the two side door frames 22 are connected to the smaller door frame 10 using multiple connecting components 30, resulting in multiple connection nodes between the upper door frame 21 and the two side door frames 22 and the smaller door frame 10. This improves the stability of the larger door frame 20 when installed on the smaller door frame 10. Here, the upper door frame 21 and the smaller door frame 10 can be connected and fixed using two spaced-apart connecting components 30, while the two side door frames 22 and the smaller door frame 10 can be connected and fixed using three spaced-apart connecting components 30 arranged sequentially. It should be noted that the number and arrangement of the connecting components 30 used to connect and fix the upper door frame 21 and the two side door frames 22 to the smaller door frame 10 can be specifically set according to the usage requirements, and will not be elaborated here.

[0050] like Figure 4 As shown, in one embodiment, the clip 31 has a first bent edge 311, and the snap-fit ​​plate 32 has a second bent edge 322, which abuts against the first bent edge 311. The connector 33 is configured as a self-tapping screw 331, which passes through both the first bent edge 311 and the second bent edge 322 and is screwed onto the small door frame 10. This allows for the assembly and fixation of the snap-fit ​​plate 32 and the clip 31 onto the small door frame 10, facilitating the fixing of the connecting assembly 30 to the small door frame 10. Here, a single self-tapping screw 331 is used to simultaneously fix the clip 31 and the snap-fit ​​plate 32 to the small door frame 10. It is understood that in other embodiments, the first bent edge 311 of the clip 31 and the second bent edge 322 of the snap-fit ​​plate 32 can be fixed to the small door frame 10 separately using self-tapping screws 331, or the connector 33 can be configured as a stainless steel screw; these details will not be elaborated upon here.

[0051] like Figure 3 , Figure 4 As shown, in one embodiment, the number of hooks 321 is configured in multiple rows, with the multiple rows of hooks 321 arranged sequentially and at intervals along the depth direction of the slot 301; wherein, the barbs 201 of the door frame 20 can engage with the multiple rows of hooks 321 respectively. This allows the barbs 201 of the door frame 20 to engage with the multiple rows of hooks 321 sequentially during insertion into the slot 301, enabling the barbs 201 of the door frame 20 to be locked multiple times during insertion, preventing the door frame 20 from falling off during installation, thus further facilitating the installation of the door frame 20. It should be noted that during the installation of the door frame 20, the user can repeatedly tap the door frame 20 to drive it into place.

[0052] like Figure 4As shown, in one embodiment, a bent plate 312 is formed on the locking strip 31. The bent plate 312 can abut against the door sleeve 20 inserted into the slot 301, thereby limiting the door sleeve 20 to the locking plate 32 and engaging the door sleeve 20 with the hook 321. In other words, the locking strip 31 can prevent the door sleeve 20 from detaching from the locking plate 32, thus ensuring the stability of the door sleeve 20 installation.

[0053] As can be seen from the above, when the staff needs to carry out on-site installation of the door frame 20, the upper door frame 21 and the two side door frames 22 can be inserted and locked to make the door frame 20 a whole structure; then, the self-tapping screws 331 are used to lock the clip 31 and the snap plate 32 to the small door frame 10; then, the entire door frame 20 is aligned with the slot 301 formed between the clip 31 and the snap plate 32 and inserted. During this process, the door frame 20 can be tapped until the U-shaped bend 202 on the door frame 20 can be against the outer facade 200 of the elevator shaft.

[0054] In addition, this application also provides an elevator, including the elevator door frame structure 100 described above.

[0055] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0056] Those skilled in the art should recognize that the above embodiments are only used to illustrate the present utility model and are not intended to limit the present utility model. Any appropriate changes and variations made to the above embodiments within the scope of the essential spirit of the present utility model shall fall within the scope of protection claimed by the present utility model.
