[0049] See Figures 1-11 This is one embodiment of a shelf handle proposed in this utility model. The shelf handle 100 is snapped onto the shelf 200, which is composed of multiple support rods. The shelf handle 100 can be mounted on multiple support rods, and the shelf handle 100 is mounted on at least the first support rod 201 and the second support rod 202. The shelf 200 can be a shelf in a dishwasher, a shelf in a refrigerator, or other shelves used for holding containers.

[0050] A shelf handle 100 includes a handle body 10 and a decorative panel 20. The handle body 10 is integrally formed and has a receiving cavity 13 with a lower opening. The handle body 10 has a body portion 11 and engaging plates 12 located at both ends of the body portion 11. The body portion 11 and the engaging plates 12 surround the receiving cavity 13. The engaging plates 12 are provided with receiving grooves 121 for accommodating at least a first support rod 201 and a second support rod 202 on the shelf 200. The first support rod 201 and the second support rod pass through the receiving cavity 13 and engage with the receiving grooves 121 to install and fix the shelf handle 100. The upper end of the receiving groove 121 is provided with a first engaging groove 1211 that matches the first support rod 101, and the lower end is provided with a lower engaging protrusion 125 that is limited to the lower side of the second support rod 202 to prevent the first support rod 101 and the second support rod 102 from moving downward and dislodging relative to the receiving groove 121. The receiving groove 121 has a first groove wall 123 and a second groove wall 124 arranged opposite to each other. The lower locking protrusion 125 extends closer to the first groove wall 123 along the second groove wall 124. The lower locking protrusion 125 and the first groove wall 123 form an installation opening 1216 for the receiving groove 121. The first support rod 101 and the second support rod 102 both enter the receiving groove 121 upward through the installation opening 1216.

[0051] In this embodiment, the shelf handle 100 is snapped onto the shelf 200. The gap between the lower locking protrusion 125 and the first groove wall 123 forms an installation opening 1216, allowing the support rod on the shelf 200 to slide directly into the installation opening 1216 without the need for tools, significantly shortening the installation time and facilitating rapid installation. The first locking groove 1211 engages with the first support rod 201, forming an upper positioning; the lower locking protrusion 125 hooks onto the lower side of the second support rod 202, forming a lower limit, which helps to improve the firmness of the connection between the shelf handle 100 and the shelf 200, making it less prone to shaking or falling off. The shelf handle 100 can be installed and removed by hand without tools; and the handle body 10 has an integral molded structure, so there are no exposed sharp parts, avoiding hand cuts during installation and improving safety.

[0052] In some other embodiments, the lower protrusion 125 may also be provided on the first groove wall 123.

[0053] In this embodiment, the shelf handle 100 is installed on the front side of the shelf 200, enabling the shelf 200 to be pulled out in the front-back direction. A first support rod 201 and a second support rod 202 are arranged vertically, with the diameter of the first support rod 201 being larger than the diameter of the second support rod 202. A lower locking protrusion 125 and a second groove wall 124 form a limiting groove 1217 that matches the second support rod 202. The inner side of the lower locking protrusion 125 is located inside the vertical plane containing the center of the cross-section of the second support rod 202. The distance from the inner side of the lower locking protrusion 125 to the vertical plane containing the center of the cross-section of the second support rod 202 is greater than half the radius of the second support rod 202.

[0054] In some embodiments of this application, a first locking protrusion 1231 and a second locking protrusion 1241 are provided close to each other along the first groove wall 123 and the second groove wall 124, and a locking opening 1212 is formed between the first locking protrusion 1231 and the second locking protrusion 1241 to form a first locking groove 1211. The width of the locking opening 1212 is smaller than the diameter of the first support rod 201, that is, the distance between the first locking protrusion 1231 and the second locking protrusion 1241 is smaller than the diameter of the first support rod 201; such that when the first support rod 201 passes upward through the locking opening 1212, the deformation of the first groove wall 123 and / or the second groove wall 124 causes the body part 11 to deform, and then the first support rod 201 engages with the upper side of the first locking protrusion 1231 and the second locking protrusion 1241, thereby achieving engagement of the first support rod 201. When the shelf handle 100 is installed, it moves from top to bottom, so that the first support rod 201 passes through the mounting openings 1216 on the left and right sides, and enters the receiving cavity 13. The first support rod 201 also passes through the receiving groove 121 on the locking plate 12. Then, it continues to move upward, so that the first support rod 201 passes through the locking opening 1212 and the second support rod 202 passes through the mounting opening 1216. The first support rod 201 is locked in the first locking groove 1211, and the second support rod enters the receiving groove 121 and is located on the upper side of the lower locking protrusion 125.

[0055] In some embodiments of this application, the locking plate 12 is provided with a guide opening 122 connected to the lower side of the mounting opening 1216. The guide opening 122 is wider in the downward direction. By providing the guide opening 122, it is beneficial for the first support rod 201 and the second support rod 202 to reach the mounting opening 1216, thereby improving the installation efficiency of the shelf handle 100. Specifically, a first guide surface 1221 and a second guide surface 1221 that are far apart from each other in the downward direction are provided at the lower end of the first groove wall 123 and the lower end of the second groove wall 124. The upper end of the second guide surface 1221 is connected to the lower locking protrusion 125. The first guide surface 1221 and the second guide surface 1221 surround to form the guide opening 122, and the upper end of the guide opening 122 is connected to the mounting opening 1216. The width of the mounting opening 1216 is smaller than the diameter of the second support rod 202.

[0056] In some embodiments of this application, a plurality of support ribs 14 are provided in the receiving cavity 13, spaced apart and arranged in parallel. The support ribs 14 have support slots 141 that match the first support rod 201. The support slots 141 have the same structure as the upper end of the receiving groove 121, thereby achieving matching with the first support rod 201, increasing the contact area between the handle body 10 and the shelf 200, and increasing the stability of the shelf handle 100 after installation.

[0057] In some embodiments of this application, the body portion 11 has an inner plate portion 111 and an outer plate portion 112 disposed opposite to each other, and an upper connecting portion 113 connecting the inner plate portion 111 and the outer plate portion 112. A first groove wall 123 is connected to the inner plate portion 111, and a second groove wall 124 is connected to the outer plate portion 112. The support rib 14 has a vertical portion 142 extending outward along the inner plate portion 111, and the upper end of the vertical portion 142 is connected to the inner groove wall of the support groove 141. The vertical portion 142 is used to increase the structural strength of the body portion 11; and the vertical portion 142 is limited to the inner side of the first support rod 101 and the second support rod 102, increasing the stability of the shelf handle 100 after installation; and during the installation of the shelf handle 100, the vertical portion 142 can play a guiding role for the first support rod 101 and the second support rod 102.

[0058] In some embodiments of this application, the outer plate portion 112 is connected to the outer wall of the support groove 141. The outer plate portion 112 has multiple openings 1121, and a support rib 1122 is provided between two adjacent openings 1121. The support rib 1122 is located outside the first support rod 101 and the second support rod 102. By providing multiple openings 1121, it is beneficial to reduce the weight of the handle body 10 and reduce the amount of injection molding material. The outer plate portion 112 serves to limit the outward movement of the first support rod 101 and the second support rod 102, which helps to increase the stability of the shelf handle 100 after it is fixed. The support rib 1121 and the support rib 14 are alternately arranged in the left-right direction.

[0059] In some embodiments of this application, an inwardly extending limiting protrusion 11221 is provided on the support rib 1122, and the limiting protrusion 11221 is located on the outside of the second support rod 202; thereby limiting the second support rod 202.

[0060] In some embodiments of this application, the shelf handle 100 further includes a decorative panel 20 installed on the outside of the handle body 10. The handle body 10 is made of injection molding, and the decorative panel 20 is made of sheet metal, preferably stainless steel. The outside of the handle body 10 is provided with a mounting groove 15 for installing the decorative panel 20, and the decorative panel 20 is located in the mounting groove.

[0061] In some embodiments of this application, a plurality of engaging claws 21 are provided at one end of the decorative panel 20, and a mounting hole 151 for the engaging claws 21 to pass through is provided at the bottom of the mounting groove 15. The engaging claws 21 have an inwardly extending inner extension 211 and an engaging portion 212 that bends and extends along the inner side of the inner extension 211.

[0062] In some embodiments of this application, the receiving cavity 13 is provided with a engaging surface 131 that matches the engaging portion 21, and a relief groove 132 located at the top of the receiving cavity 13, the relief groove 132 being used to avoid the engaging portion 21. The engaging portion 212 is formed by bending upward along the inner side of the inner extension 211. When the decorative panel 20 is installed, the decorative panel 20 is tilted, and then the engaging claw 21 is passed through the mounting hole 151.

[0063] In some embodiments of this application, the decorative panel 20 is provided with an inwardly extending insertion claw 22. An insertion hole 152, matching the insertion claw 22, is formed at the bottom of the mounting groove 15. The length of the insertion claw 22 is greater than the depth of the insertion hole 152. After the insertion claw 22 is inserted into the insertion hole 152, the portion extending into the receiving cavity 13 is bent to form a limiting structure, preventing the insertion claw 22 from dislodging and increasing the stability of the decorative panel 20 after installation.

[0064] In some embodiments of this application, an inner groove 133 communicating with the insertion hole 152 is provided on the inner wall of the receiving cavity 13, and the bent portion of the insertion claw 22 after being inserted into the insertion hole 152 is located within the inner groove 133. The inner groove 133 is provided so that the bent portion of the insertion claw 22 does not protrude from the inner wall of the receiving cavity 13, avoiding interference when the shelf handle 100 is installed onto the shelf 200; and also helping to ensure the stability of the decorative panel 20 after installation.
