The plastic elevator car coaming shown in fig. 1 comprises a panel 1 and a first clamping part 2 arranged on the panel 1, wherein the panel 1 and the first clamping part 2 are plastic products; the first engaging part 2 is elastically engaged with the car wall, and the panel 1 shields the engaging position of the first engaging part 2 with the car wall.

Wherein, the plastic elevator car coaming is arranged in the elevator and mainly plays the roles of shielding and decoration. Plastics system elevator sedan-chair bounding wall is generally installed in elevator car's bottom, and there is the ventilation gap elevator car bottom to avoid the car to seal completely, and plastics system elevator sedan-chair bounding wall is used for sheltering from this department ventilation gap of protection. In this ventilation slot, air is introduced into the interior of the car, and the panel 1 serves as an external protection.

After the plastic elevator car coaming is installed, people can only observe the outer surface of the panel 1. The first engaging portion 2 functions to fix the panel 1 for connection with the elevator car, and the joint is shielded by the panel 1. The length of the first engaging portion 2 is smaller than the length of any one surface of the panel 1, and the panel 1 needs to completely shield the first engaging portion 2. When avoiding panel 1 to install on the elevator, first block portion 2 causes and blocks, exposes too big gap between panel 1 and the elevator.

In addition, because of the wide use of metal, the traditional car boarding is made of metal, and the car boarding made of metal has high rigidity and high strength, but lacks elasticity and plasticity. The existing installation mode of the metal car coaming is that a clamping hole is formed in the metal car coaming, and the clamping hole is compacted and fixed by using an elastic piece. It can be understood that the traditional metal car coaming is relatively complex in both manufacturing process and combination mode.

The utility model discloses a plastic products has the elastoplasticity, can go into to the integrated configuration that corresponds after extrusion elastic deformation in the card. Such as extrusion from PVC material, which is inexpensive. Compared with the traditional metal material, the plastic material preparation can reduce the material cost and simplify the production process. For example, the melting point of plastic is lower than that of metal, so that the production requirement can be reduced, and the cost can be reduced. The first engaging portion 2 made of a plastic material has excellent elasticity and can be elastically deformed. Manufacturing first clamping parts 2 with different shapes or sizes, and clamping the first clamping parts into different gap structures in a deformable manner; the problem that the metal piece lacks deformability and the fixing mode is complex is solved. In addition, it should be noted that plastic products are lighter than metal products, are easier to carry and reduce the load of the components.

In an embodiment, the first engaging portion 2 is a first engaging arrow 21 or a first accommodating cavity 22.

In the first engaging portion 2 shown in fig. 1 and fig. 7, the first engaging arrow 21 can be compressed and contracted to be restored to an original shape so as to be engaged with the corresponding cavity; the first receiving chamber 22 can be expanded by pressing and restored to its original shape to hook the corresponding component.

In one embodiment, the first engaging arrow 21 includes a first connecting bar 211 having one end disposed on the panel 1 and a first triangular engaging head 212 disposed on the other end of the first connecting bar 211, and the first triangular engaging head 212 is elastically engaged in the car wall. In the embodiment of the present application, a shape of a first engaging arrow 21 is disclosed, a first connecting bar 211 extends a first triangular engaging head 212 from the panel 1, and the first triangular engaging head 212 has elasticity and plasticity, and can be engaged in a gap to fix the panel 1. As can be seen in fig. 1, the panel 1 is in the shape of an inverted "L" having a horizontal plane and a vertical plane, the end of the vertical plane being connected perpendicularly to the end of the horizontal plane for forming a relative enclosure with the internal corner of the bottom of the car, blocking the internal ventilation structure, and the first snap-on arrow existing in this enclosure, fixing the panel 1. Specifically, the first snap arrow 21 is mounted on the vertical face of the panel 1, parallel to the horizontal face of the panel 1, on the inside of the horizontal face and the vertical face, the inside being the side where the vertical face and the horizontal face join to form an inner angle. When the first triangular chuck 212 is engaged with the car wall, the horizontal surface of the panel 1 presses against the car wall, preventing the first engaging arrow 21 from further penetrating into the car wall, and the first engaging arrow 21 restricts the panel 1 from disengaging. If the panel 1 needs to be disassembled, a force in the opposite direction is applied to the panel 1, and a large force is needed to deform the first engagement arrow 21 again. Generally, the elevator car has a mounting slot and mounting chamber, which is fitted with the first snap arrow 21. The first triangular chuck 212 is compressed and deformed when sliding into the mounting gap, and finally enters the mounting cavity to be restored and hooked. It should be mentioned that the first connecting strip 211 can slide in the mounting slot of the car wall.

In one embodiment, two bottom corners of the first triangular clamping head 212 protrude outwards relative to the other end of the first connecting bar 211 to form barbs for limiting the first triangular clamping head 212 to be elastically clamped in the car wall and then separated from the car wall.

The first triangular chuck 212 is triangular, the front end is pointed, and the rear end is gradually enlarged to form a barb. When the first triangular chuck 212 moves in the mounting gap, the barb deforms and compresses until entering the mounting cavity, the size is reduced, the shape of the barb is larger than that of the mounting gap, and then the first triangular chuck 212 is hooked in the mounting cavity.

In an embodiment, the first receiving cavity 22 includes a first engaging plate 221 with one end connected to the panel 1 and a second engaging plate 222 with one end connected to the panel 1, and the first engaging plate 221 and the second engaging plate 222 are separated by a certain distance to form a chamber elastically engaged with the car wall.

In another embodiment, the first receiving cavity 22 shown in fig. 7 is used for receiving a fastening structure for hooking the car wall. For example, the engaging structure of the car wall is arrow-shaped, so that the first accommodating chamber 22 is inserted into the arrow-shaped engaging structure. In the insertion process, the clamping structure is inserted into a cavity between the first clamping plate 221 and the second clamping plate 222, the first clamping plate 221 and the second clamping plate 222 are bent outwards until the clamping structure completely enters the cavity between the first clamping plate 221 and the second clamping plate 222, and the first clamping plate 221 and the second clamping plate 222 are restored to the original state, so that the cavity is reduced in volume and the clamping structure is hooked. If the panel 1 needs to be detached from the installation, the panel 1 is repeatedly swung up and down to slide the first engaging plate 221 and the second engaging plate 222 outward.

In one embodiment, a first hooking portion 100 extending in the direction of the second engaging plate 222 is provided at the other end of the first engaging plate 221, and a second hooking portion 200 extending in the direction of the first engaging plate 221 is provided at the other end of the second engaging plate 222; after the second accommodating chamber 42 is elastically engaged with the plastic elevator car wall, the first and second hooking portions 100 and 200 are used to restrict the first accommodating chamber 22 from being detached from the car wall.

Wherein the first hooking part 100 and the second hooking part 200 are disposed at the entrance of the chamber between the first engaging plate 221 and the second engaging plate 222. The inlet of the chamber is narrowed to form a gap. The engaging structure of the car wall first enters the gap, so that the first engaging plate 221 and the second engaging plate 222 are forced to bend outward, and the gap is enlarged. Until the engaging structure completely enters the chamber, the first engaging plate 221 and the second engaging plate 222 are restored to their original shapes, and the gap is smaller than the engaging structure, so that the first hooking portion 100 and the second hooking portion 200 hook the engaging structure, and the panel 1 cannot be separated.

In one embodiment, the first engaging portion 2 extends from one side of the panel 1 to the other side of the panel 1.

The one side of the panel 1 refers to one of the left and right sides of the panel 1 as shown in fig. 1 and 7, and the first engaging portion 2 extends from one of the left and right sides of the panel 1 to the other side, so that the first engaging portion 2 is continuously and transversely provided on the panel 1. It can be understood that the first engaging portion 2 has a transverse length consistent with that of the panel 1, and is not broken, so that the first engaging portion 2 has a large volume, is thick, has high rigidity, and can easily support the weight of the panel 1. In addition, the first engaging portion 2 also serves as a rigid strip for increasing the rigidity of the panel 1, so that the panel is not easily deformed.

In the rest plastic elevator car coamings, a plurality of small clamping pieces at intervals are arranged on the plastic elevator car coamings, so that the panel 1 is fixed. However, because the plurality of small clamping pieces are not arranged consecutively, each clamping piece has small volume, poor rigidity and bearing capacity, and can not be used as a rigid strip of the panel 1, so that the performance of the plastic elevator car coaming is low.

In one embodiment, the surface of the panel 1 is provided with a coating film for protecting the panel 1 from corrosion, and the coating film comprises PVC or PP or PET material.

Wherein, plastic materials are used for film covering, and the materials include but are not limited to PVC, PP, PET and other materials. Different plastic coatings can be used according to different process requirements. Wherein, the price of PVC is the lowest, the material of PP material is the lightest, and the physical and chemical stability of PET is higher. The plastic film is used, various colors and textures are easily added into the film, the beautiful decoration effect is achieved, and meanwhile the panel 1 can be protected from corrosion.

As shown in fig. 2, the car fixing member is used for being clamped and installed with a plastic elevator car coaming, and includes a mounting plate 3 and a second clamping portion 4, the mounting plate 3 is installed on the car wall, the second clamping portion 4 is arranged on the mounting plate 3, and the mounting plate 3 and the second clamping portion 4 are made of elastic materials; the second engaging portion 4 is used for engaging and combining with the plastic elevator car boarding.

The mounting plate 3 mainly plays a mounting role, so that the mounting plate 3 is fixed on the car wall and can have various shapes. Generally, the mounting plate 3 is manufactured as a vertical flat plate, mounted vertically on the car floor or close to the car wall, for ease of assembly and structure reduction. In addition, the upper end of the mounting plate 3 has a corner portion extending toward the second engaging portion 4, and this structure has the function of blocking rainwater and facilitating taking.

The car mounting is as the connecting piece between plastics system elevator sedan-chair bounding wall and the car, fixes the car mounting on car lateral wall earlier, installs plastics system elevator sedan-chair bounding wall in the car mounting again, and at this moment, the car mounting is fixed by subassembly such as bolt, and plastics system elevator sedan-chair bounding wall is fixed with car mounting block, can manually use external force to make plastics system elevator sedan-chair bounding wall install or dismantle on the car mounting. The first engaging portion 2 and the second engaging portion 4 are corresponding engaging members. The car mounting is small, and the structure is simple and easy, makes easily, only makes the fixed action between plastics system elevator sedan-chair bounding wall and car to can not cause the stopping to inside air flow. The size and the shape of the car fixing part can be improved, and the installation of plastic elevator car coamings of different specifications and different styles can be met. This car mounting adopts for elastic material, because metal material makes technology and material cost higher on the one hand, on the other hand elastic material can carry out the block combination better.

Accordingly, in one embodiment, the car mount and the plastic elevator car fence are both made of plastic, and the plastic elevator car fence is lighter than a metal fence, so that the car mount for fixing the plastic elevator car fence is lighter in weight bearing without requiring too high rigidity.

In an embodiment, the second engaging portion 4 is a second engaging arrow 41 or a second accommodating cavity 42.

In the second engaging portion 4 shown in fig. 2 and fig. 8, the second engaging arrow 41 can be pressed and contracted to be restored to the original shape so as to be engaged with the corresponding first accommodating cavity 22; the second receiving chamber 42 can be expanded by pressing and restored to its original shape to hook the corresponding component. It is understood that the mounting plate 3 is a vertical plate, the vertical surface is mounted on the car wall, and the second engaging portion 4 extends horizontally. At the moment, the car fixing piece is fixed and immovable, and the plastic elevator car coaming is actively clamped into the car fixing piece.

In one embodiment, the second engaging arrow 41 includes a second connecting bar 411 having one end disposed on the panel 1 and a second triangular engaging head 412 disposed on the other end of the second connecting bar 411, and the second triangular engaging head 412 is elastically engaged in the plastic elevator car enclosure.

In the embodiment of the present application, a shape of a second engaging arrow 41 is disclosed, and a second triangular engaging head 412 is extended from the panel 1 by a second connecting bar 411, and the second triangular engaging head 412 can be engaged by the first receiving cavity 22. In the clamping process, the second triangular clamping head 412 and the first accommodating cavity 22 are deformed to a certain degree, so that the second triangular clamping head 412 is contracted, and the first accommodating cavity 22 is enlarged. In consideration of the clamping requirement and the load-bearing requirement, the second triangular clamping head 412 has certain hardness on the basis of having certain deformation capacity, and the sliding of the installation position of the second triangular clamping head 412 and the first accommodating cavity 22 in the installation process is avoided. The second triangular clamp 412 finally enters the installation chamber to be restored and hooked. It should be mentioned that the second connecting strip 411 can slide in the first receiving cavity 22.

In one embodiment, two bottom corners of the second triangular clamping head 412 protrude outwards relative to the other end of the second connecting strip 411 to form barbs for limiting the second triangular clamping head 412 to be elastically clamped behind the plastic elevator car enclosure plate and separated from the plastic elevator car enclosure plate.

The second triangular chuck 412 is triangular, the front end is pointed, and the rear end is gradually enlarged to form a barb. When the first triangular chuck 212 moves in the installation gap of the first accommodating cavity 22, the barb deforms and compresses until entering the first accommodating cavity 22, the size is reduced, the barb shape is larger than the installation gap, and then the second triangular chuck 412 is hooked in the first accommodating cavity 22.

In an embodiment, the second receiving cavity 42 includes a third engaging plate 421 having one end connected to the mounting plate 3 and a fourth engaging plate 422 having one end connected to the mounting plate 3, and the third engaging plate 421 and the fourth engaging plate 422 are separated by a certain distance to form a cavity elastically engaged with the plastic elevator car cover plate.

In another embodiment, the second receiving cavity 42 is used for receiving the hooking first engaging arrow 21. For example, the first engagement arrow 21 is arrow-shaped, and the first engagement arrow 21 is inserted into the second accommodation chamber 42. That is, the first engaging plate 221 and the second engaging plate 222 are continuously inserted into the cavity between the third engaging plate 421 and the fourth engaging plate 422, and the third engaging plate 421 and the fourth engaging plate 422 are restored to their original shapes until the engaging structure completely enters the cavity between the third engaging plate 421 and the fourth engaging plate 422, so that the cavity is reduced in volume and the engaging structure is hooked.

In one embodiment, a third hooking portion 300 extending in the direction of the fourth engaging plate 422 is provided at the other end of the third engaging plate 421, and a fourth hooking portion 400 extending in the direction of the third engaging plate 421 is provided at the other end of the fourth engaging plate 422; after the second accommodating cavity 42 is elastically clamped and mounted with the plastic elevator car boarding, the third hooking part 300 and the fourth hooking part 400 are used for limiting the second accommodating cavity 42 to be separated from the plastic elevator car boarding.

The third hooking portion 300 and the fourth hooking portion 400 are disposed at an entrance of a chamber between the third engaging plate 421 and the fourth engaging plate 422, and the entrance of the chamber is narrowed to form a gap. The first engaging arrow 21 first enters the gap, so that the first engaging plate 221 and the second engaging plate 222 are forced to bend outward, and the gap is enlarged. Until the engaging structure completely enters the chamber, the first engaging plate 221 and the second engaging plate 222 are restored to their original shapes, and the gap is smaller than the engaging structure, so that the first hooking portion 100 and the second hooking portion 200 hook the engaging structure, and the panel 1 cannot be separated.

In one embodiment, the second engaging portion 4 extends from one side of the mounting plate 3 to the other side of the mounting plate 3.

The one side of the mounting plate 3 refers to one of the left and right sides of the mounting plate 3 as shown in fig. 2 and 8, and the second engaging portion 4 extends from one of the left and right sides of the mounting plate 3 to the other side, so that the second engaging portion 4 is continuously provided in the mounting plate 3 in the lateral direction. It can be understood that the second clamping part 4 has the same transverse length as the mounting plate 3 and is not broken, so that the second clamping part 4 has large volume, is thick and has high rigidity, and can easily support the weight of the plastic elevator car coaming connected with the second clamping part. In addition, the second engaging portion 4 also serves as a rigid strip for increasing the rigidity of the mounting plate 3, so that the mounting plate 3 is not easily deformed.

In other car fixing parts, a plurality of small clamping pieces are arranged at intervals, so that the connecting effect of the plastic elevator car coaming is realized. However, since the small engaging members are not arranged consecutively, each engaging member has a small volume, is rigid, has poor load-bearing capacity, and cannot serve as a rigid strip of the mounting plate 3, so that the performance of the car fixing member is low.

Both of the combination structures shown in figures 3 and 9 include plastic elevator car fenders and car mounts that are snap fit to each other.

The following detailed description will be given with reference to various examples:

the first embodiment is as follows:

Example two:

the plastic elevator car shroud shown in fig. 4 has a first snap arrow 21; the car fixture as shown in fig. 5 has a second receiving chamber 42; the car fixing member is mounted in an elevator car, and the plastic elevator car boarding is inserted into the car fixing member, and the car fixing member and the plastic elevator car boarding are assembled into a combined structure as shown in fig. 6.

The second embodiment is similar to the first embodiment in combination structure, except that the first triangular clamp 212 in the second embodiment has only one bottom corner for hooking, correspondingly, the corresponding second accommodating cavity 42 has only one hooking portion, and the third locking plate 421 without the third hooking portion 300 on the second accommodating cavity 42 is inclined and attached to the first connecting bar 211. When the first engaging portion 2 is inserted into or withdrawn from the second receiving cavity 42, the third engaging plate 421 needs to be pressed against and overcome the resistance to enlarge the gap. Wherein, the third snap-fit plate 421 that lacks the third hooking portion 300 is disposed at the end far away from the mounting plate 3, so as to reduce the connection area between the mounting plate 3 and the third snap-fit plate 421, and the third snap-fit plate 421 is easily elastically deformed.

Example three:

the plastic elevator car enclosure shown in fig. 7 has a first receiving cavity 22; the car fixture as shown in fig. 8 has a second snap arrow 41; the car fixing member is mounted in an elevator car, and the plastic elevator car boarding is inserted into the car fixing member, and the car fixing member and the plastic elevator car boarding are assembled into a combined structure as shown in fig. 9.
