Description

Technical Field

[0001] The present application relates to the field of elevator equipment, and in particular to an elevator landing door frame. Background Art

[0002] The elevator door frame is the structure around the elevator door in the building. It is usually located at the elevator stop on the floor. It is installed on the wall around the elevator door frame to protect and decorate the elevator door and wall. At present, the elevator door frame is mainly made of bent metal. In order to ensure smooth door opening, there will be a 4-8mm gap between the elevator door frame and the floor door.

[0003] At present, the European elevator standard EN81-20 clearly stipulates that for horizontal sliding glass doors, corresponding measures must be taken to prevent children from dragging their hands. One of the requirements is that the gap between the door frame and the floor door should not be greater than 4mm. Generally, elevator companies reduce the gap between the door frame and the floor door to reduce the possibility of pinching people's fingers or foreign objects falling between the door frame and the floor door.

[0004] Regarding the above-mentioned related technologies, the inventor believes that since the elevator shaft is built when the floors are constructed, it is difficult to reduce the gap between the door frame and the floor door during the installation process. After reducing the gap between the door frame and the floor door, the floor door is prone to deformation due to the temperature difference caused by sunlight, and is prone to scratching with the door frame. Summary of the invention

[0005] In order to solve the problem that the gap between the door frame and the floor door may pinch people's fingers or foreign objects may fall between the door frame and the floor door, the present application provides an elevator floor station door frame.

[0006] The present application provides an elevator landing door frame adopting the following technical solution:

[0007] An elevator landing door cover comprises a support body and an inner lining body connected to the support body. A receiving groove is provided on the side of the inner lining body, and a soft anti-scratch piece is inserted in the receiving groove.

[0008] By adopting the above technical solution, when installing the elevator, the soft anti-scratch component contacts the side wall of the floor door, shielding the gap between the floor door and the door frame, reducing the possibility of pinching people's fingers in the gap between the floor door and the door frame or foreign objects falling between the floor door and the door frame and affecting the normal sliding of the floor door, while also ensuring the normal sliding of the floor door.

[0009] Optionally, the soft anti-scratch component is an elastic rubber strip.

[0010] By adopting the above technical solution, the gap between the floor door and the door frame is covered by an elastic rubber strip to reduce the possibility of pinching people's fingers in the gap between the floor door and the door frame; at the same time, during the operation of the floor door, the floor door will cause the elastic rubber strip to undergo a slight elastic deformation. The excellent elasticity, acid and alkali resistance and wear resistance of the elastic rubber strip can ensure the smooth operation of the floor door, while also reducing the possibility of scratching the floor door.

[0011] Optionally, the hardness of the elastic rubber strip is 30-60HA.

[0012] By adopting the above technical solution and selecting an elastic rubber strip within a specific hardness range, the elastic rubber strip has good elasticity and wear resistance, can meet the requirements of adjusting the gap between the layer door and the door frame, and has a long service life.

[0013] Optionally, one end of the elastic rubber strip extending out of the accommodating groove is arranged in an arc shape.

[0014] By adopting the above technical solution, the contact area between the elastic rubber strip and the landing door is reduced, and the friction between the elastic rubber strip and the landing door can be reduced to a certain extent, which is conducive to the smooth operation of the landing door.

[0015] Optionally, the accommodating groove is L-shaped or inverted T-shaped.

[0016] By adopting the above technical solution, the possibility of the elastic rubber strip escaping from the accommodating groove is reduced.

[0017] Optionally, the lining body is made of PVC resin.

[0018] By adopting the above technical solution, PVC resin is used to ensure that the lining body has a fixed shape while reducing the weight of the door frame, making it easier for workers to construct.

[0019] Optionally, the lining body has a cavity, and the cavity is triangular or honeycomb-shaped.

[0020] By adopting the above technical solution, while ensuring that the lining body has high strength, the amount of raw materials used in making the lining body can be reduced, saving the cost of raw materials.

[0021] Optionally, the support body is made of stainless steel, carbon steel plate or copper plate.

[0022] By adopting the above technical solution, the strength of the door cover is ensured and the service life of the door cover is prolonged.

[0023] Optionally, the support body has a thickness of 0.5-1.2 mm.

[0024] By adopting the above technical solution, while ensuring that the door frame has a certain strength, the use of raw materials can be saved, and the weight of the door frame can be reduced, which is convenient for workers to construct.

[0025] Optionally, the support body and the lining body are connected by gluing or screws.

[0026] By adopting the above technical solution, it is convenient for workers to assemble the door frame.

[0027] In summary, the present application includes at least one of the following beneficial technical effects:

[0028] 1. The present application uses a soft anti-scratch member to adjust the gap between the floor door and the door frame, thereby reducing the possibility of the gap between the floor door and the door frame pinching a person's fingers or a foreign object falling between the floor door and the door frame and affecting the normal sliding of the floor door, and also reduces the possibility of scratches between the floor door and the door frame;

[0029] 2. The present application utilizes the combination of a support body and an inner lining body, which can reduce the weight of the door frame while ensuring the basic use functions of the door frame, making it easier for workers to construct. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] The following is combined with Figure 1-3 This application is described in further detail.

[0035] The embodiment of the present application discloses an elevator landing door frame.

[0036] Example 1

[0037] Reference Figure 1 and Figure 2, is the state after the door cover is installed, and the door cover is connected to the wall 1. The door cover includes a rectangular lining body 3 and a support body 4 covered on the side of the lining body 3, and the support body 4 and the lining body 3 are bonded by glue. The door cover can be connected to the wall 1 through an L-shaped connecting plate 11, and the L-shaped connecting plate 11 is connected to the wall 1 through screws 12. The door cover and the L-shaped connecting plate 11 can be connected by welding or screws 12.

[0038] Reference Figure 2 The inner lining body 3 is provided with a clearance groove 31 along the height direction of the inner lining body 3, and the bottom of the clearance groove 31 is provided with an inclined surface 32 connected to two adjacent right-angled sides of the inner lining body 3 to enhance the strength of the inner lining body 3. The inner lining body 3 is made of PVC resin, and the PVC resin is used to reduce the overall weight of the door frame, which is convenient for the staff to install the door frame.

[0039] Reference Figure 2 The lining body 3 has a honeycomb-shaped cavity 33 along the height direction of the lining body 3. The honeycomb-shaped cavity 33 can not only enhance the overall strength of the lining body 3, but also reduce the weight of the door frame and reduce the cost of raw materials.

[0040] Reference Figure 2 The side of the lining body 3 facing the floor door 2 is provided with an L-shaped receiving groove along the height direction of the lining body 3. An elastic rubber strip 34 is arranged in the receiving groove. The elastic rubber strip 34 is also L-shaped to reduce the possibility of the elastic rubber strip 34 escaping from the receiving groove. One end of the elastic rubber strip 34 extends out of the receiving groove and protrudes 3-6 mm from the plane of the lining body 3. In actual installation, the gap between the door frame and the floor door 2 is 3-6 mm. According to actual needs, the thickness of the elastic rubber strip 34 protruding from the plane of the lining body 3 can be limited so that the elastic rubber strip 34 can contact the floor door 2, while reducing the gap between the floor door 2 and the door frame, without affecting the normal sliding of the floor door 2. In addition, when adjusting the gap between the floor door 2 and the door frame, the floor door 2 can squeeze the elastic rubber strip 34, so that the elastic rubber strip 34 undergoes elastic deformation, thereby achieving the purpose of adjusting the gap between the floor door 2 and the door frame.

[0041] Reference Figure 2 The end of the elastic rubber strip 34 extending out of the receiving groove is arranged in an arc shape to form an arc-shaped tip to reduce the friction between the elastic rubber strip 34 and the landing door 2, so that the landing door 2 can slide smoothly and maintain stable operation. The hardness of the elastic rubber strip 34 can be selected from 30-60HA. The present embodiment 1 selects an elastic rubber strip 34 with a hardness of 40HA. By limiting the hardness of the elastic rubber strip 34, the elasticity of the elastic rubber strip 34 can meet the requirement of being able to adjust the gap between the landing door 2 and the door frame, and at the same time, the elastic rubber strip 34 can have a certain wear resistance, have a long service life, and reduce the frequency of maintenance of the door frame by the staff.

[0042] Reference Figure 2 The support body 4 can be made of stainless steel, carbon steel plate or copper plate. In this embodiment 1, stainless steel is used to make the support body 4, so that the support body 4 has high strength. The thickness of the support body 4 is controlled within the range of 0.5-1.2 mm. The thickness of the support body 4 in this embodiment 1 is 1 mm. By limiting the thickness of the support body 4, the strength of the support body 4 is sufficient to support the lining body 3 and the support body 4 has a long service life, while the use of stainless steel materials can be saved, reducing the cost of raw materials.

[0043] The implementation principle of Example 1 is as follows: when assembling the door cover, the elastic rubber strip 34 is inserted into the receiving groove from the end of the inner lining body 3 or squeezed into the receiving groove from the side of the inner lining body 3 by applying a certain pressure, and the door cover is installed on the wall 1 through the L-shaped connecting plate 11. When installing the floor door 2, the elastic rubber strip 34 contacts the floor door 2, so that the gap between the floor door 2 and the door cover is shielded by the elastic rubber strip 34, reducing the possibility of pinching the fingers of people in the gap between the floor door 2 and the door cover, and also reducing the possibility of foreign objects falling between the floor door 2 and the door cover and affecting the normal operation of the floor door 2.

[0044] In addition, when the elevator is running in the hoistway, a piston effect will be generated, compressing the air in the direction of movement, causing the air to pass through the gap between the floor door 2 and the door frame to generate noise. The elastic rubber strip 34 has the function of blocking the air from passing through the gap between the floor door 2 and the door frame, thereby achieving the purpose of sound insulation and noise reduction.

[0045] Example 2

[0046] Reference Figure 3 The difference between this embodiment and the embodiment 1 is that the support body 4 and the lining body 3 are connected by screws 12. The receiving groove and the elastic rubber strip 34 are both in an inverted T shape, and the cavity 33 is a right triangle.

[0047] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
