Abstract
Description
[Technical Field]
[0001] This utility model relates to the field of hardware accessories technology, and more particularly to a perimeter edging structure for glass heating plates used in glass plate processing. [Background Technology]
[0002] As consumers' living standards continue to improve, their demands for the quality and usability of furniture in daily life are also increasing. Consequently, various hardware accessories have become widely used in consumers' lives. From kitchen utensils and tableware to bathroom fixtures, electric heaters, and other household appliances, a large number of hardware accessories are involved in their production.
[0003] However, the hardware accessories involved in this case include transparent glass panels. These transparent glass panels are composed of two layers of transparent glass and an adhesive layer between them. Due to manufacturing factors, it is easy for adhesive residue to remain at the edges of the transparent glass panels, or for the edges to naturally form right angles or sharp corners where the edges intersect. If transparent glass panels are directly applied to products such as electric towel racks or electric heaters, it is easy for users to accidentally injure their fingers during use.
[0004] Due to the material properties of the transparent glass plate itself, it is not possible to install power cords around the transparent glass plate or between transparent glass plates for heating purposes. [Utility Model Content]
[0005] In view of this, the technical problem to be solved by this utility model is to provide a perimeter edging structure for a glass heating plate that not only avoids injury to the user's fingers during use, but also facilitates the installation of various power cords or heating wires.
[0006] To address the aforementioned technical problems, the present invention provides a perimeter edging structure for a glass heating plate, applicable to the field of electric towel racks or electric heaters. It includes a heating plate body with its own heating function and a metal edge frame component installed around the perimeter of the heating plate body.
[0007] The hardware edge frame component includes two horizontally arranged long frame bars, two vertically arranged short frame bars, and a corner connector located at the intersection of the long frame bars and the short frame bars.
[0008] The upper inner end of the long and short frame bars is provided with a strip-shaped power cord receiving space for installing the power cord, and the lower inner end of the long and short frame bars is provided with an edge receiving space for installing the four edges of the transparent glass plate.
[0009] The metal edge frame component completely encloses the right angles and sharp angles formed by the edges around the heating plate body.
[0010] During installation, first, insert the heating plate body into the edge receiving space on all four sides. Then, install the power cord inside the power cord receiving space. Next, connect the two long frame bars and the two short frame bars together using corner connectors. This allows the heating plate body to be enclosed within the planar receiving space formed by the two long frame bars and the two short frame bars. Finally, tighten the screws through the corner connectors to lock the positions between the adjacent long frame bars and the short frame bars, thus completely enclosing the heating plate body within the metal edge frame formed by the two long frame bars and the two short frame bars.
[0011] Further defined, the corner connector includes a corner L-shaped part placed at the intersection of the long frame bar and the short frame bar, and a locking screw that securely connects the corner L-shaped part to the long frame bar or the corner L-shaped part to the short frame bar.
[0012] Further defined, the corner L-shaped part includes a part body located at the intersection, a transverse connecting arm located at the upper end of the part body and connected to one end of the long strip of the frame, a transverse bending arm located inside the transverse connecting arm and bent inward on both sides, and a transverse locking screw hole located on the side of the transverse bending arm for locking screws to pass through and fix; a longitudinal connecting arm located at the lower end of the part body and connected to one end of the short strip of the frame, a longitudinal bending arm located inside the longitudinal connecting arm and bent inward on both sides, and a longitudinal locking screw hole located on the side of the longitudinal bending arm for locking screws to pass through and fix.
[0013] Further defining the frame's long bar, it includes a long horizontal bar with a hollow rectangular cross-section, wider at the top and narrower at the bottom. Inside the long horizontal bar, on both sides, are long inner baffles for use with the horizontal connecting arms. A power cord receiving space is formed at the upper end of the long inner baffle for installing a power cord or heating wire, and an edge receiving space is formed at the lower end of the long inner baffle for installing the edge of the heating plate body. The internal structure of the frame's long bar is the same as that of the frame's short bar.
[0014] The beneficial technical effects of this utility model are as follows: The transparent glass plate includes a heating plate body with its own heating function and a metal edge frame component installed around the periphery of the heating plate body.
[0015] The hardware edge frame component includes two horizontally arranged long frame bars, two vertically arranged short frame bars, and a corner connector located at the intersection of the long and short frame bars.
[0016] Because the metal edge frame component completely encloses the right angles and sharp corners formed by the edges around the heating plate body, it solves the technical problem in the prior art where the right angles or sharp corners directly contact the user's fingers during use, thereby preventing the user's fingers from being injured during use.
[0017] Because the upper inner ends of the long and short frame bars are provided with power cord receiving spaces, and the lower inner ends of the long and short frame bars are provided with edge receiving spaces; during installation, the four edges of the heating plate body are placed inside the edge receiving spaces at the lower inner ends of the long and short frame bars, and the power cord or heating wire is installed inside the power cord receiving space, so that the entire heating plate body is wrapped inside the planar receiving space formed by the interconnection of the two long and two short frame bars; this installation method solves the technical problem that power cords cannot be installed between heating plate bodies, thus facilitating the installation of various power cords or heating wires.
[0018] The technical solution of this utility model will be further described in detail below with reference to the accompanying drawings and embodiments. [Attached Image Description]

[0032] Please refer to Figures 1 to 9 As shown, the following describes a perimeter edging structure for a glass heating plate, applicable to the fields of electric towel racks or electric heaters. The perimeter edging structure includes a heating plate body 1 with its own heating function, and metal edge frame members installed around the perimeter of the heating plate body 1.
[0033] The hardware edge frame component includes two horizontally arranged long frame bars 2, two vertically arranged short frame bars 3, and a corner connector located at the intersection of the long frame bars 2 and the short frame bars 3.
[0034] The corner connector includes a corner L-shaped part 4 located at the intersection of the long frame bar 2 and the short frame bar 3, and a locking screw 5 that securely connects the corner L-shaped part 4 to the long frame bar 2 or the corner L-shaped part 4 to the short frame bar 3. The corner L-shaped part 4 includes a part body located at the intersection, a transverse connecting arm 401 located at the upper end of the part body and connected to one end of the long frame bar 2, a transverse bending arm 402 located inside the transverse connecting arm 401 with both sides bent inward, and a transverse locking screw hole 403 located on the side of the transverse bending arm 402 for the locking screw 5 to pass through and be fixed; a longitudinal connecting arm 404 located at the lower end of the part body and connected to one end of the short frame bar 3, a longitudinal bending arm 405 located inside the longitudinal connecting arm 404 with both sides bent inward, and a longitudinal locking screw hole 406 located on the side of the longitudinal bending arm 405 for the locking screw 5 to pass through and be fixed.
[0035] The frame long bar 2 includes a long horizontal bar with a hollow rectangular cross-section that is larger at the top and smaller at the bottom. Long inner baffles 201 are respectively provided on both sides inside the long horizontal bar for use with the horizontal connecting arm 401. A power cord receiving space 202 for installing power cord or heating wire is formed at the upper end of the long inner baffle 201, and an edge receiving space 203 for installing the edge of the heating plate body 1 is formed at the lower end of the long inner baffle 201. The internal structure of the frame long bar 2 is the same as the internal structure of the frame short bar 3.
[0036] During installation, first, insert the four edges of the heating plate body 1 into the edge receiving space 203, install the power cord inside the power cord receiving space 202, and then connect the two long frame bars 2 and the two short frame bars 3 together through the corner connectors, so that the heating plate body 1 is wrapped inside the planar receiving space 204 formed by the two long frame bars 2 and the two short frame bars 3. Finally, the locking screws 5 pass through the corner connectors to lock the position between the adjacent long frame bars 2 and the short frame bars 3, so that the heating plate body 1 is completely wrapped inside the hardware edge frame formed by the two long frame bars 2 and the two short frame bars 3.
[0037] The long frame bars 2 are arranged in parallel horizontally, while the short frame bars 3 are arranged in parallel vertically. The long frame bars 2 and the adjacent short frame bars 3 are connected together by corner connectors to form the planar receiving space 204. The heating plate body 1 is installed and fixed inside the planar receiving space 204.
[0038] The metal edge frame component completely encloses the right angles and sharp corners formed by the edges around the heating plate body 1; it solves the technical problem in the prior art where the right angles or sharp corners directly contact the user's fingers during use, thereby avoiding the occurrence of injury to the user's fingers during use.
[0039] Because the upper inner end of the long frame bar 2 and the short frame bar 3 is provided with a power cord receiving space 202, and the lower inner end of the long frame bar 2 and the short frame bar 3 is provided with an edge receiving space 203; during installation, the four edges of the heating plate body 1 are placed inside the edge receiving space 203 at the lower inner end of the long frame bar 2 and the short frame bar 3, and the power cord or heating wire is installed inside the power cord receiving space 202. This installation method solves the technical problem that power cords cannot be installed between the heating plate bodies, thereby facilitating the installation of various power cords or heating wires.

This electric towel rack includes a support base 9 that directly contacts the wall surface, a plurality of connecting rods 6 mounted on the support base 9, and a support rod 7 mounted on each connecting rod 6. The glass plate 8, which consists of a heating plate body and a metal edge frame, can be directly mounted on the support rod 7. This also achieves the purpose of preventing injury to the user's fingers during use and facilitating the installation of various power cords or heating wires.
[0041] Please refer to Figure 11 As shown, the four-sided edging structure described in this case is applied to a floor-standing electric heater. The electric heater includes support legs 10 on both sides that are in direct contact with the ground, and a glass plate 101 installed between the support legs 10 on both sides. The glass plate 101 is composed of a heating plate body and a metal edge frame. This structure can also prevent users from injuring their fingers during use and facilitate the installation of various power cords or heating wires.
[0042] Please refer to Figure 12 As shown, the four-sided edging structure described in this case is applied to a wall-mounted electric heater. This heater includes a bracket 30 that directly contacts the wall where it is installed, and a glass plate 301 mounted on two brackets 30.
