Abstract
Description
Technical Field
[0001] This utility model relates to the field of heater assembly technology, specifically a handle structure for a desktop heater. Background Technology
[0002] The handle of a heater is a portable component designed on the outside of the unit. It is mainly used for users to move the device safely. It is usually located on the top or side and is connected to the body by a physical structure (such as a buckle, screw or one-piece molding). Its core functions include portability (avoiding direct contact with the hot body), safety (anti-detachment design such as screw fixing or buckle locking) and space adaptability (detachable, foldable or rotatable).
[0003] In existing technologies, the connection methods between the heater and the handle are divided into screw fastening and magnetic connection. Screw fastening uses a pre-set threaded hole to fix the handle by the screw and the threaded hole. It usually requires the assistance of tools to fix it. It has strong stability but is inconvenient to disassemble. Repeated disassembly and assembly or over-tightening can wear down the threads. Small parts are easy to be lost during installation and disassembly. Magnetic connection uses a strong magnet to embed the handle into the body. It has limited weight capacity. High-frequency vibration during equipment operation may cause the magnetic handle to gradually shift. Long-term exposure to the high temperature air outlet of the heater may weaken the performance of the magnet and pose a risk of dropping the machine. The metal handle conducts heat through the magnet, and it may be hot to the touch after holding it for a long time.
[0004] Therefore, this utility model provides a handle structure for a desktop heater that is easy to assemble and disassemble and can be mechanically self-locking. Utility Model Content
[0005] To address the problems of inconvenience in disassembly and assembly or easy detachment during use in existing technologies, a handle structure for a desktop heater has been designed.
[0006] The technical solution adopted by this utility model to solve its technical problem is: a handle structure for a desktop heater, including a heater cover and a handle detachably connected to its outer side, with fixing components at both ends of the handle and a separation component on the inner side of the heater cover; the fixing component includes a fixing pin slidably connected to the handle, which is compressed and reset by an elastic element set on the inner side of the handle, so that the handle and the heater cover can be assembled without tools; the separation component, through a support foot slidably connected to the inner side of the heater cover, drives the separation pin set on its inner side to move horizontally, pushing out and resetting the fixing pin, so that the handle can be separated from the heater cover.
[0007] Preferably, circular locking blocks are fixedly connected to both sides of the handle, the heater cover has locking grooves on both sides, the handle ends are rounded, and the heater has rounded grooves on both sides.
[0008] Preferably, the fixing component includes fixing grooves formed at both ends of the handle, a fixing plate fixedly connected to the middle of the fixing groove, a fixing pin slidably connected to the middle of the fixing plate, an elastic element fixedly connected to the outside of the fixing pin, the elastic element being fixedly connected to the fixing plate, and the fixing pin being able to engage with the slot.
[0009] Preferably, the separation assembly includes a button slidably connected to the top of the heater cover, a support foot fixedly connected to the button, a separation pin slidably connected to the heater cover, a support foot slidably engaged with the separation pin, a limit rod slidably connected to the inner side of the separation pin, and an elastic element two fixedly connected to the inner side of the separation pin, the elastic element two being fixedly connected to the limit rod.
[0010] Preferably, the pin heads of both the fixing pin and the separating pin are set as bevels.
[0011] Preferably, a storage column is fixedly connected to one side of the handle, and a limiting plate is fixedly connected to the end of the storage column away from the handle.
[0012] Preferably, a fixing block is fixedly connected to the side of the handle near the storage column. A limiting groove is opened on the inner side of the fixing block. An elastic element three is fixedly connected to one side of the limiting groove. A cylindrical pin is fixedly connected to the other end of the elastic element three. The cylindrical pin is slidably connected to the fixing block.
[0013] Preferably, the side of the fixing pin near the elastic element one and the side of the cylindrical pin near the elastic element three are both fixedly connected to the limiting piece.
[0014] The beneficial effects of this utility model are:
[0015] (1) The handle structure of the desktop heater described in this utility model realizes tool-free quick disassembly and assembly of the heater handle through the sliding cooperation of the circular block and the slot and the automatic spring-locking mechanism of the fixing pin, which simplifies the maintenance or cleaning process. Its rigid snap-fit ensures the safety of handling the heater during use and improves the disassembly and assembly efficiency of the heater handle.
[0016] (2) The handle structure of the desktop heater described in this utility model is designed in conjunction with the storage column and the arc groove to ensure that the wire is not easy to loosen after winding. The cylindrical pin limits the wire to prevent it from slipping off, avoiding the risk of dragging during transportation and reducing the wear of the wire during the use of the heater.

Detailed Implementation
[0026] To make the technical means, technical features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0027] Example: Figures 1-7 As shown, the present invention discloses a handle structure for a desktop heater, comprising a heater cover 5 and a handle 1 detachably connected to its outer side. The handle 1 has fixing components 2 at both ends, and a separation component 3 is provided on the inner side of the heater cover 5. The fixing component 2 includes a fixing pin 24 slidably connected to the handle 1. Through compression and reset by an elastic element 23 located on the inner side of the handle 1, the handle 1 and the heater cover 5 can be assembled without tools. The separation component 3, through a support leg 35 slidably connected to the inner side of the heater cover 5, drives the separation pin 31 located on its inner side to move horizontally, pushing out and resetting the fixing pin 24, allowing the handle 1 to be separated from the heater cover 5. Through the cooperation of the fixing component and the separation component, the heater handle can be disassembled and assembled without tools, facilitating the maintenance and cleaning of the heater.
[0028] In this embodiment, circular locking blocks 4 are fixedly connected to both sides of the handle 1, and slots are provided on both sides of the heater cover 5. The two ends of the handle 1 are set as arcs, and arc grooves are provided on both sides of the heater. When assembling the heater handle 1, the circular locking blocks 4 on both sides of the handle 1 are inserted into the slots on both sides of the heater cover 5 and pushed downward. The circular locking blocks 4 slide along the slots, and the arc grooves limit the handle 1, keeping the handle 1 suspended in the air. This avoids the heat conduction caused by long-term operation, which can lead to hot hands when holding it. After installation, the handle 1 remains flat with the side wall of the heater, reducing the risk of hooking other items when the protruding structure is transported or moved.
[0029] In this embodiment, the fixing component 2 includes fixing grooves 21 formed at both ends of the handle 1. A fixing plate 22 is fixedly connected to the middle of the fixing groove 21. A fixing pin 24 is slidably connected to the middle of the fixing plate 22. An elastic element 23 is fixedly connected to the outside of the fixing pin 24. The elastic element 23 is fixedly connected to the fixing plate 22. The fixing pin 24 can be engaged with the slot. When the handle 1 is installed, the fixing pin 24 is pressed by the heater cover 5 and slides along the fixing plate 22, compressing the elastic element 23. When the circular locking block 4 slides to the bottom of the slot, the fixing pin 24 slides to the top of the slot. The squeezing force on the elastic element 23 disappears, pushing the fixing pin 24 to reset. The fixing pin 24 is popped out and engaged with the slot, so that the handle 1 is fixed on the heater cover 5, which meets the requirement of assembling the heater handle 1 without tools.
[0030] In this embodiment, the separation component 3 includes a button 36 slidably connected to the top of the heater cover 5, a support leg 35 fixedly connected to the button 36, a separation pin 31 slidably connected to the heater cover 5, a support leg 35 slidably engaging with the separation pin 31, a limit rod 33 slidably connected to the inner side of the separation pin 31, and an elastic element 34 fixedly connected to the inner side of the separation pin 31, the elastic element 34 being fixedly connected to the limit rod 33. When it is necessary to remove the handle 1, the button 36 on the top of the heater cover 5 is pressed, and the support leg 35 slides downward along the slide groove 32 with the button 36. The vertical sliding of the support leg 35 causes the separating pin 31 to move towards the slot side, compressing the elastic element 34. The fixing pin 24 is pushed out of the slot by the separating pin 31. While pressing the button 36, the handle 1 is pulled upward, and the circular block 4 slides to the top of the slot. When the button 36 is released, the squeezing force on the elastic element 34 disappears, pushing the separating pin 31 to reset. The separating pin 31 pushes the support leg 35 upward, causing the button 36 to reset. After the circular block 4 is disengaged from the slot, the handle 1 is disassembled, which meets the requirement of easy disassembly of the heater handle 1.
[0031] In this embodiment, the pin heads of both the fixing pin 24 and the separating pin 31 are set as bevels; this prevents the fixing pin 24 from being stuck by the heater cover 5 and unable to slide along the fixing plate 22 when the handle 1 is installed, and prevents the circular block 4 from being stuck by the separating pin head when it moves towards the top of the slot, thus preventing the circular block 4 from being unable to disengage and affecting the normal use of the heater.
[0032] In this embodiment, a storage column 6 is fixedly connected to one side of the handle 1, and a limiting plate is fixedly connected to the end of the storage column 6 away from the handle 1. When the heater needs to be moved or is not in use, the wire is wound around the storage column 6, and the limiting plate limits the wire to prevent the wire from falling off.
[0033] In this embodiment, a fixing block 7 is fixedly connected to the side of the handle 1 near the storage column 6. A limiting groove is opened on the inner side of the fixing block 7. An elastic element 8 is fixedly connected to one side of the limiting groove. A cylindrical pin 9 is fixedly connected to the other end of the elastic element 8. The cylindrical pin 9 is slidably connected to the fixing block 7. After the wire is wrapped around the storage column 6, the wire near the plug is inserted into the fixing block 7. The wire pushes the cylindrical pin 9 away from each other, squeezing the elastic element 8. When the wire is pushed to the bottom of the fixing block 7, the elastic element 8 pushes the cylindrical pin 9 to reset and limit the wire, preventing the wire from falling off. This makes the heater easy to move and store.
[0034] In this embodiment, the fixed pin 24 near the elastic element 23 and the cylindrical pin 9 near the elastic element 8 are both fixedly connected to a limiting piece; when the elastic element 8 pushes the cylindrical pin 9 to reset, the cylindrical pin 9 is limited to prevent it from being pushed out of the limiting groove and affecting the normal use of the structure.
[0035] Working principle: When assembling the handle 1 of the heater, insert the circular locking blocks 4 on both sides of the handle 1 into the slots on both sides of the heater cover 5 and push them downwards. When the circular locking blocks 4 slide to the bottom of the slot, the fixing pin 24 is popped out and engages with the slot, fixing the handle 1 to the heater cover 5. When the heater needs to be moved or is not in use, wrap the wire around the storage column 6. After wrapping, insert the wire near the plug into the fixing block 7, and the cylindrical pin 9 limits the wire. When the handle 1 needs to be disassembled, press the button 36 and pull the handle 1 upwards. The circular locking blocks 4 slide to the top of the slot. Release the button 36 to disengage the circular locking blocks 4 from the slot, completing the disassembly of the handle 1.
