Description
Technical Field
[0001] The present application relates to the technical field of door seals, and particularly to a door seal structure. Background Art
[0002] A door seal is a strip-shaped article used to close a portal or utensil, commonly seen in the sealing of doors and windows, playing roles such as sound insulation, dust prevention, anti-freezing, and heat preservation. A door seal is an important component of a steam oven structure. The door seal of a steam oven is usually made of silicone or special rubber material, which can ensure that the high temperature and steam inside the steam oven do not leak during operation, and at the same time prevent external cold air from entering and affecting the cooking effect.
[0003] The door seal of a steam oven is usually snap-fitted and fixed to the door frame of the cabinet. To facilitate snap-fitting the snap-fitting part of the door seal into the snap-fitting groove opened in the door assembly, a buffer cavity is provided in the snap-fitting part. When snap-fitting and installing the snap-fitting part, due to the softness of the material of the door seal, when the snap-fitting part enters the snap-fitting groove, the buffer cavity is squeezed until the snap-fitting part enters the snap-fitting position of the snap-fitting groove, and the buffer cavity resumes its shape, and the snap-fitting part is tightly engaged with the snap-fitting groove. However, when the depth of the snap-fitting groove of the door assembly is deep, the snap-fitting part cannot penetrate into the snap-fitting position of the snap-fitting groove for snap-fitting, or the buffer cavity cannot resume its shape after being squeezed, causing the door-latching part of the door seal to bulge. When the cabinet and the door are closed, the cabinet and the door cannot be closely attached, resulting in the possibility of steam leakage and water leakage, thus requiring remanufacturing the snap-fitting part, and the applicability of the door seal is low. Utility Model Content
[0004] In order to improve the applicability of the door seal, the present application provides a door seal structure.
[0005] A door seal structure provided by the present application adopts the following technical solution:
[0006] A door seal structure includes:
[0007] A snap-fitting part, including a snap-fitting member and an extension member. The snap-fitting member is connected to the extension member. The snap-fitting member is provided with a buffer cavity, and the snap-fitting member is provided with a first ventilation hole penetrating the buffer cavity. The extension member is provided with an extension cavity, and the wall of the extension cavity is provided with a second ventilation hole. The extension cavity is communicated with the buffer cavity through the second ventilation hole;
[0008] A door-latching part, connected to the extension member.
[0009] By adopting the above technical solution, when the door seal strip needs to be installed, it is snapped into the snap groove. The extension piece provides a function of deepening the depth for the snap piece to penetrate into the snap groove, so that the snap piece can penetrate into the snap part of the snap groove for snapping. If there is a possibility that the buffer cavity cannot be restored when the snap piece is snapped into the snap groove, the snap piece is extruded and deformed, and the snap piece is deformed and extended towards the extension cavity. The extension cavity provides a deformation range for the compressive deformation of the snap piece, reducing the possibility of the door latching part being deformed and bulged due to the deformation of the snap piece, improving the applicability of the door seal strip, enabling the door latching part to be stably installed on the door assembly, and improving the sealing performance between the box body and the box door.
[0010] Optionally, the snap piece and the extension piece are integrally formed.
[0011] By adopting the above technical solution, the snap piece and the extension piece are integrally formed, reducing the possibility of the snap piece being deformed and causing the snap piece and the extension piece to split or break, thereby improving the structural stability of the door seal strip.
[0012] Optionally, the door latching part includes a first latching piece and a second latching piece. The first latching piece is connected to the extension piece, and the second latching piece is connected to a side of the first latching piece away from the extension piece. The first latching piece includes a first latching surface on the side away from the extension piece, and the first latching surface is located at one end of the first latching piece close to the extension piece. The second latching piece includes a second latching surface, and the second latching surface forms an angle greater than 90° with the first latching surface.
[0013] By adopting the above technical solution, when the box door is closed on the box body, the box door contacts the second latching piece first, and then fits with the first latching piece, so that the box door fits on the first latching piece and the second latching piece. The second latching piece provides a buffering performance for the box door to be closed on the box body, reducing the possibility of the box body being damaged due to long-term impact when the box body is directly closed on the first latching piece.
[0014] Optionally, the cross-sectional area of the end of the second latching piece away from the first latching piece is larger than the cross-sectional area of the end close to the first latching piece.
[0015] By adopting the above technical solution, when the box door is attached to the second latching piece, it is convenient for the second latching piece to be bent, thereby improving the buffering performance of the second latching piece.
[0016] Optionally, the end of the second latching piece away from the first latching piece is provided with anti-slip stripes, and the anti-slip stripes are convexly arranged on one side of the second latching piece.
[0017] By adopting the above technical solution, when the box door is closed at the position of the box body, the second latching piece and the box door are in contact with each other and slightly offset. The anti-slip stripes can increase the friction between the box door and the second latching piece, so that the plane of the second latching piece can be flatly attached to the box door, improving the sealing effect at the fitting position between the box door and the second latching piece.
[0018] Optionally, the first engaging member includes a first positioning section, a lapping section, and a second positioning section. The first positioning section is connected to the lapping section. One side of the lapping section away from the first positioning section is connected to the second positioning section. The lengthening member is connected to the lapping section, and the second engaging member is connected to the lapping section.
[0019] By adopting the above technical solution, the first positioning section and the second positioning section pre-position the installation position of the engaging member, enabling the engaging member to be accurately engaged at the door frame position of the box body, thereby improving the installation efficiency.
[0020] Optionally, the second positioning section is perpendicular to the lapping section, and one end of the second positioning section away from the lapping section is located on the side of the lapping section close to the lengthening member.
[0021] By adopting the above technical solution, when the door seal needs to be installed, the second positioning section is inserted into the pre-positioning of the installation position, enhancing the structural stability of the door seal installation.
[0022] Optionally, a first folded line protrusion is provided on one side of the engaging member close to the second positioning section, and a second folded line protrusion is provided on the side of the engaging member away from the first folded line protrusion. The number of the second folded line protrusions is multiple.
[0023] By adopting the above technical solution, an inner groove is formed between the first folded line protrusion, the second positioning section and the lapping section, reducing the possibility of the second positioning section detaching from the door frame. Multiple folded line protrusions are provided to form a multi-stage lip structure. Each lip structure has a sealing effect, enabling the door seal and the door frame to form a multi-stage sealing effect, thereby improving the sealing effect at the connection position between the door seal and the box body.
[0024] In summary, the present application includes at least one of the following beneficial technical effects:
[0025] 1. When the door seal needs to be installed, it is snapped into the snap groove. The lengthening member provides a function of deepening the insertion depth of the engaging member into the snap groove, enabling the engaging member to be inserted into the snap part of the snap groove for snapping. If there is a possibility that the buffer cavity cannot be restored when the engaging member is snapped into the snap groove, the engaging member is squeezed and deformed, and the engaging member deforms and extends towards the lengthening cavity. The lengthening cavity provides a deformation range for the compressive deformation of the engaging member, reducing the possibility of the engaging member deforming and causing the door latching part to bulge, improving the applicability of the door seal, enabling the door latching part to be stably installed on the door assembly, and improving the sealing performance between the box body and the box door;
[0026] 2. When the door of the box is closed on the box body, the door of the box contacts the second fitting, and then fits with the first fitting, so that the door of the box fits on the first fitting and the second fitting. The second fitting provides buffering performance for the door of the box to be closed on the box body, reducing the possibility of damage to the box body caused by long-term impact when the box body is directly closed on the first fitting;
[0027] 3. An inner groove is formed between the first folded line protrusion, the second positioning section and the overlapping section, reducing the possibility of the second positioning section detaching from the door frame. Multiple folded line protrusions are provided to form a multi-stage lip structure. Each lip structure has a sealing effect, enabling the door seal strip and the door frame to form a multi-stage sealing effect with each other, improving the sealing effect at the connection position between the door seal strip and the box body.

[0033] The following is a further detailed description of the present application in conjunction with the attached Figures 1-3 Drawings.
[0034] The embodiment of the present application discloses a door seal strip structure.
[0035] Refer to Figure 1 and Figure 2, A door seal structure, including a clamping part and a door fastening part. The clamping part is connected to the door fastening part and integrally formed. The length direction of the clamping part is parallel to the length direction of the door fastening part. The clamping part includes a clamping member 1 and an extension member 2. One side of the clamping member 1 is fixedly connected to one side of the extension member 2. The clamping member 1 is provided with a buffer cavity 11, and the clamping member 1 is provided with a first ventilation hole 111 penetrating the buffer cavity 11. Along the length direction of the extension member 2, the extension member 2 is provided with an extension cavity 21, and the cavity wall of the extension cavity 21 is provided with a second ventilation hole 211. The extension cavity 21 is communicated with the buffer cavity 11 through the second ventilation hole 211. The door fastening part is fixedly connected to the side of the extension member 2 away from the clamping member 1.
[0036] When installing the door seal, the clamping member is snapped into the clamping groove. The extension member 2 provides a depth extension function for the clamping member 1 to penetrate deeper into the clamping groove, so that the clamping member 1 can be snapped into the clamping part of the clamping groove. If there is a possibility that the buffer cavity 11 cannot recover when the clamping member 1 is snapped into the clamping groove, the clamping member 1 is extruded and deformed, and the clamping member 1 deforms and extends towards the extension cavity 21. The extension cavity 21 provides a deformation range for the compressive deformation of the clamping member 1, reducing the possibility of the clamping member 1 deforming and causing the door fastening part to bulge, improving the applicability of the door seal, enabling the door fastening part to be stably installed on the door assembly, improving the sealing performance between the box body and the box door. At the same time, when the box door is closed on the box body, the contraction of the buffer cavity 11 can provide a buffering effect. The gas in the buffer cavity 11 circulates through the first ventilation hole 111, and the gas in the extension cavity 21 circulates through the second ventilation hole 211 into the buffer cavity 11 and then circulates through the first ventilation hole 111. The buffer cavity 11 and the extension cavity 21 cooperate with each other to provide an effective shock absorption effect for the box door.
[0037] To reduce the possibility of the clamping member 1 and the extension member 2 splitting or breaking, the clamping member 1 and the extension member 2 are integrally formed.
[0038] The door fastening part includes a first fastening member 3 and a second fastening member 4. The first fastening member 3 is fixedly connected to the side of the extension member 2 away from the clamping member 1, and the second fastening member 4 is fixedly connected to the side of the first fastening member 3 away from the extension member 2. The first fastening member 3 includes a first lapping surface 31 on the side away from the extension member 2, and the first lapping surface 31 is located at one end of the first fastening member 3 close to the extension member 2. The second fastening member 4 includes a second lapping surface 41, and the second lapping surface 41 is located on the side of the second fastening member 4 close to the clamping part and adjacent to the first lapping surface 31. The second lapping surface 41 and the first lapping surface 31 form an angle greater than 90°.
[0039] When the box door is closed on the box body, the box door contacts the second engaging member 4 first, and then fits with the first engaging member 3, so that the box door fits on the first overlapping surface 31 of the first engaging member 3 and the second overlapping surface 41 of the second engaging member 4. The second engaging member 4 provides buffering performance for the box door to close on the box body, reducing the possibility that the box body directly closes on the first engaging member 3, causing the box door to collide with the box body through the first engaging member 3 and resulting in damage to the box body due to long-term impact.
[0040] In addition, to facilitate the bending of the second engaging member 4 when it touches the box door and improve the buffering performance of the second engaging member 4, in the cross-sectional area of the second engaging member 4, the cross-sectional area of the end of the second engaging member 4 far from the first engaging member 3 is larger than the cross-sectional area of the end of the second engaging member 4 close to the first engaging member 3, so that the closer the second engaging member 4 is to the first engaging member 3, the thinner the second engaging member 4 becomes.
[0041] Refer to Figure 2 and Figure 3 As shown in, an anti-slip stripe 42 is provided at one end of the second engaging member 4 far from the first engaging member 3. The anti-slip stripe 42 is located on the second overlapping surface 41, and the anti-slip stripe 42 is convexly provided on one side of the second engaging member 4. The length direction of the anti-slip stripe 42 is the same as the length direction of the second engaging member 4.
[0042] When the box door is closed at the position of the box body, the second engaging member 4 contacts the box door and undergoes a slight offset. The anti-slip stripe 42 can increase the friction between the box door and the second engaging member 4, making the plane of the second engaging member 4 fit flatly on the box door and improving the sealing effect at the fitting position of the box door and the second engaging member 4.
[0043] The first engaging member 3 includes a first positioning section 32, an overlapping section 33, and a second positioning section 34. The first positioning section 32 is fixedly connected to the overlapping section 33. The side of the overlapping section 33 far from the first positioning section 32 is connected to the second positioning section 34. The side of the extension member 2 far from the clamping member 1 is fixedly connected to one side of the overlapping section 33. The extension member 2 is located between the first positioning section 32 and the second positioning section 34. The second engaging member 4 is fixedly connected to the side of the overlapping section 33 far from the extension member 2. The side of the overlapping section 33 far from the extension member 2 and the side of the first positioning member are smooth connection surfaces, and this smooth connection surface is the first overlapping surface 31 in this embodiment.
[0044] The first positioning section 32 and the second positioning section 34 pre-position the installation position of the clamping member 1, enabling the clamping member 1 to be accurately clamped at the door frame position of the box body and improving the installation efficiency.
[0045] One side of the first positioning section 32 and the side of the overlapping section 33 close to the extension member 2 are located on the same plane. The second positioning section 34 is perpendicular to the overlapping section 33, and one end of the second positioning section 34 far from the overlapping section 33 is located on the side of the overlapping section 33 close to the extension member 2.
[0046] When installing the door seal, the second positioning section 34 is inserted into the pre-positioning of the installation position to enhance the structural stability of the door seal installation.
[0047] On one side of the clamping member 1 close to the second positioning section 34, a first folding convex 12 is provided. The length direction of the first folding convex 12 is parallel to the length direction of the clamping member 1. An inner groove is formed between the first folding convex 12, the second positioning section 34 and the overlapping section 33, facilitating the insertion of the door frame into the inner groove to improve the installation stability of the door seal. On the side of the clamping member 1 away from the first folding convex 12, a second folding convex 13 is provided, and the number of the second folding convex 13 is multiple, forming a multi-stage lip structure. Each lip structure has a sealing effect, enabling the door seal and the door frame to form a multi-stage sealing effect and improving the sealing effect at the connection position between the door seal and the box body.
[0048] The implementation principle of a door seal structure in an embodiment of the present application is as follows: The clamping member 1 is fixed by being snapped into the clamping groove of the door frame of the box body. The extension member 2 provides a depth extension function for the clamping member 1 to penetrate deeper into the clamping groove, enabling the clamping member 1 to be snapped into the clamping part of the clamping groove. If there is a possibility that the buffer cavity 11 cannot recover when the clamping member 1 is snapped into the clamping groove, the clamping member 1 is squeezed and deformed, and the clamping member 1 deforms and extends towards the extension cavity 21. The extension cavity 21 provides a deformation range for the compressive deformation of the clamping member 1, reducing the possibility of the door latching part deforming and protruding due to the deformation of the clamping member 1, improving the applicability of the door seal, enabling the door latching part to be stably installed on the door assembly, and improving the sealing performance between the box body and the box door.
[0049] The above are all preferred embodiments of the present application. This embodiment is only an explanation of the present application and does not limit the protection scope of the present application in sequence. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
