Abstract
Description
TECHNICAL FIELD
[0001] The application belongs to the technical field of door locks, and particularly relates to a film body covering structure of a door lock handle.
BACKGROUND
[0002] In the production and sales process of door handles, in order to meet the market demand for different appearances, manufacturers will attach a covering film to the door handle to change its color and texture. However, when a batch of door handles of one color is produced, there will be some remaining stock that is not sold in time. When another batch of door handles of a different color needs to be produced, if the remaining door handles with covering films are attached with a covering film again, the outer covering film will be convex and not fit the surface of the door handle, thereby affecting the overall appearance. The manufacturer can only dispose of these remaining door handles, which cannot be reused, thereby undoubtedly increasing the production cost and causing waste of resources.
CONTENT OF THE UTILITY MODEL
[0003] In order to solve the problem that the door handle with a covering film cannot be reused in the prior art, thereby increasing the production cost, the application provides a film body covering structure of a door lock handle for reusing the door handle with a covering film and reducing the production cost.
[0004] The application is implemented by the following technical scheme:
[0005] The film body covering structure of the door lock handle comprises a door handle grip, a limiting end head arranged near a lock body end of the door handle grip, and a limiting end tail arranged away from the lock body end, a fitting surface for fitting the covering film is formed between the limiting end head and the limiting end tail, the protruding height of the limiting end head relative to the fitting surface is H, and the thickness of the covering film is B, wherein H is greater than or equal to 2B.
[0006] The film body covering structure of the door lock handle as described above further comprises a dividing rib arranged along the length direction of the fitting surface and connected to the limiting end head and the limiting end tail at two ends.
[0007] The film body covering structure of the door lock handle as described above is arranged on the side facing the door body.
[0008] The film body covering structure of the door lock handle as described above is arranged on the side facing the door body.
[0009] The film body covering structure of the door lock handle as described above is arranged on the side facing the door body.
[0010] In the membrane covering structure of the door lock handle as described above, the protrusion height of the limiting end relative to the contact surface is the same as the protrusion height of the limiting end relative to the contact surface.
[0011] As described above, in the membrane covering structure of the door lock handle, the circumference of the arc near the limiting end on the bonding surface is S1, the circumference of the arc near the limiting end is S2, the short arc length of the covering membrane is L1, the long arc length is L2, and the width of the dividing rib is D, wherein S1-D=L1 and S2-D=L2.
[0012] The membrane covering structure of the door lock handle described above is made of PVC material.
[0013] As described above, in the membrane covering structure of the door lock handle, the radius of the covering membrane corresponds to the length of the dividing rib.
[0014] As described above, the membrane covering structure of the door lock handle has a transition surface that bends outward at the end of the limiting end away from the contact surface.
[0015] Compared with the prior art, this application has the following advantages:
[0016] The membrane covering structure of the door lock handle disclosed in this application forms a bonding surface for the membrane by setting a limiting end and a limiting end on the door handle handle. The protrusion height H of the limiting end relative to the bonding surface is greater than or equal to twice the thickness B of the membrane. This ensures that when re-wrapping a membrane-covered door handle, the newly applied membrane is effectively constrained by the limiting end and the limiting end, and will not exceed the protrusion height of the limiting end relative to the bonding surface. This avoids the problem of the outer membrane protruding outwards, ensuring the overall harmony of the door handle. Furthermore, it allows the reuse of leftover membrane-covered door handles from the previous batch without discarding them, thus significantly reducing production costs and minimizing resource waste.

DETAILED DESCRIPTION
[0027] In order to make the technical problems and beneficial effects of the technical solutions of the present application more clear, the present application will be further described in detail below in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and do not limit the present application.
[0028] Referring to Figures 1 to 9 , the film body covering structure of the door lock handle includes a door handle knob 1, a limiting end head 11 is arranged on the door handle knob 1 close to one end of the lock body, and a limiting end tail 12 is arranged on the door handle knob 1 away from one end of the lock body, a fitting surface 13 for fitting the covering film 2 is formed between the limiting end head 11 and the limiting end tail 12, the protruding height of the limiting end head 11 relative to the fitting surface 13 is H, and the thickness of the covering film 2 is B, wherein H≥2B.
[0029] The film body covering structure of the door lock handle of the present application forms a fitting surface for fitting the covering film by arranging the limiting end head and the limiting end tail on the door handle knob, and the protruding height H of the limiting end head relative to the fitting surface is greater than or equal to twice the thickness B of the covering film, so that when the door handle with the covering film is re-covered with the film, the newly fitted covering film can be effectively constrained by the limiting end head and the limiting end tail, and will not exceed the protruding height of the limiting end head relative to the fitting surface, thereby avoiding the problem of the outer covering film protruding outward, and ensuring the overall coordination of the door handle. The remaining covered door handle of the previous batch can be utilized without being discarded, thereby significantly reducing the production cost and reducing resource waste.
[0030] Further, as a preferred embodiment of the present solution but not limited, the fitting surface 13 is further provided with a split rib 131 arranged along the length direction thereof and connected to the limiting end head 11 and the limiting end tail 12 respectively.
[0031] In the present embodiment, the presence of the split rib 131 enables the cladding film 2 to be more closely fitted to the fitting surface 13 during the fitting process, reducing the generation of bubbles and wrinkles, thereby improving the fitting quality and appearance effect of the cladding film 2. In addition, the split rib 131 can also serve as a positioning reference for the cladding film 2, ensuring accurate alignment of the cladding film 2 during the fitting process, thereby improving production efficiency.
[0032] Further, as a preferred embodiment of the present solution but not limited, the split rib 131 is located towards the door body side. In the present embodiment, the split rib 131 is located towards the door body side, which can to some extent shield the gap between the door handle and the door body, thereby improving the overall aesthetic appearance of the door handle.
[0033] Further, as a preferred embodiment of the present solution but not limited, the split rib 131 is provided with a circular arc transition 1311 corresponding to the two sides of the fitting surface 13.
[0034] In the present embodiment, the sharp edges are avoided, thereby preventing the cladding film 2 from being damaged or wrinkled, thereby improving the fitting quality and durability of the cladding film 2. In addition, when holding the door handle, the user's hand will not easily feel the abruptness of the split rib, thereby providing a more comfortable hand feel.
[0035] Further, as a preferred embodiment of the present solution but not limited, the fitting surface 13 gradually increases in inner diameter from one end of the limiting end head 11 to the other end of the limiting end tail 12, and the cladding film 2 is in a fan ring shape.
[0036] In the present embodiment, the gradually changing inner diameter design can better adapt to the gripping needs of the door handle, providing a more comfortable hand feel, while enhancing the appearance aesthetics of the door handle. In addition, the fan ring-shaped cladding film 2 can be more closely fitted to the fitting surface 13 with a gradually changing inner diameter, thereby reducing the wrinkling or loosening of the cladding film 2 due to size mismatch, thereby improving the fitting quality and durability of the cladding film 2.
[0037] Further, as a preferred embodiment of the present solution but not limited, the protrusion height of the limiting end tail 12 relative to the fitting surface 13 is the same as the protrusion height of the limiting end head 11 relative to the fitting surface 13.
[0038] In this embodiment, the balance of the door handle during holding and use is ensured, and the feeling of discomfort or inconvenience caused by the inconsistent height of the two ends is avoided. The fitting quality and appearance effect of the cladding film 2 are improved.
[0039] Further, as a preferred embodiment of the present scheme but not limited, the circular arc length of the fitting surface 13 near one end of the limiting end head 11 is S1, the circular arc length near the limiting end tail 12 is S2, the short arc length of the cladding film 2 is L1, the long arc length is L2, and the width of the segmentation rib 131 is D, wherein S1-D=L1 and S2-D=L2.
[0040] In this embodiment, the cladding film 2 can be perfectly fitted on the fitting surface 13, avoiding the problems of wrinkling, loosening or incomplete coverage of the cladding film 2 caused by size mismatch, thereby improving the fitting quality and appearance effect of the cladding film 2. Secondly, by considering the width D of the segmentation rib 131, this design can also ensure that the cladding film 2 will not be hindered by the segmentation rib 131 during fitting, so that the cladding film 2 can be more smoothly covered on the fitting surface 13.
[0041] Further, as a preferred embodiment of the present scheme but not limited, the cladding film 2 is made of PVC material.
[0042] In this embodiment, PVC material has good mechanical properties and weather resistance, which can effectively resist friction, scratching and environmental changes in daily use, thereby prolonging the service life of the cladding film 2 and maintaining the appearance of the door handle. Secondly, PVC material is easy to process and form, and can be easily made into cladding films 2 of various shapes and sizes to adapt to door handles with different design requirements, improving the flexibility and efficiency of production. In addition, PVC material also has good chemical stability, which can resist the erosion of most chemicals, so that the cladding film 2 is not easy to discolor, deform or damage during use.
[0043] Further, as a preferred embodiment of the present scheme but not limited, the radius length of the cladding film 2 corresponds to the length of the segmentation rib 131.
[0044] In this embodiment, by controlling the radius length of the cladding film to be consistent with the length of the segmentation rib, the cladding film can be tightly fitted to the edge of the segmentation rib during installation, avoiding problems such as wrinkles, bubbles or loose fitting caused by size mismatch.
[0045] Further, as a preferred embodiment of the present scheme but not limited, the limiting end head 11 is provided with a transition curved surface 111 extending outwardly away from the fitting surface 13.
[0046] In the embodiment, the smooth transition structure can enhance the overall aesthetics of the door handle, making the appearance of the door handle more smooth and natural, and improving the product grade and attractiveness. In addition, the transition curved surface 111 can also guide the gripping action of the hand to some extent, so that the user can find the best gripping position more naturally when using the door handle, improving the convenience and comfort of use.
[0047] The working principle of the embodiment is as follows:
[0048] The film covering structure of the door lock handle of the application forms a fitting surface for the covering film by setting the limiting end and the limiting end tail on the door handle handle, and the protrusion height H of the limiting end relative to the fitting surface is greater than or equal to twice the thickness B of the covering film, so that when the door handle with the covering film is re-covered with the film, the newly pasted covering film can be effectively constrained by the limiting end and the limiting end tail, and will not exceed the protrusion height of the limiting end relative to the fitting surface, avoiding the problem of the outer covering film protruding outward, and ensuring the overall coordination of the door handle. The remaining covered film door handle of the previous batch can be utilized without being discarded, thereby significantly reducing the production cost and reducing resource waste.
[0049] The above is an embodiment provided in combination with specific content, and it is not intended that the specific implementation of the application is limited to these descriptions. Any similar structure or method as the application, or any technical deduction or replacement made on the basis of the concept of the application, should be considered as the protection scope of the application.
