[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.
[0027] Embodiment 1,
[0028] See also Figure 1-Figure 5 The utility model discloses a limited assembly base, including a base shell 10 and a connecting base 20, wherein an insertion port 15 and a first limiting portion are provided on the base shell 10. In addition, an insertion block 21 and a second limiting portion are provided on the connecting base 20. When the connecting base 20 and the base shell 10 are assembled, the insertion block 21 can be inserted into the insertion port 15. After the insertion block 21 is inserted into the insertion port 15, the second limiting portion can be pressed and abutted by the first limiting portion to prevent the insertion block 21 from being separated from the insertion port 15.
[0029] On the basis of the above structure, when the base of the position-limiting assembly of the utility model is used, the base of the position-limiting assembly can be applied to electric appliances such as heaters, electric fans, and humidifiers, and the bottom end of the main body of the electric appliance is detachably connected to the connecting seat 20. During transportation, the connecting seat 20 and the base can be in a disassembled state, which is convenient for storage and transportation. When in use, the connecting seat 20 is connected to the base in a plug-in manner, and then the bottom end of the main body of the electric appliance is connected to the connecting seat 20. In this way, the main body of the electric appliance can be used with the base as a support basis, and the use process is stable.
[0030] When the connection base 20 and the base shell 10 are assembled, the insertion block 21 of the connection base 20 is inserted into the insertion port 15 on the base shell 10. After the insertion, if the position is limited, it is easy to be separated under the action of external force. Therefore, in this embodiment, by further providing a first limit part on the connection base 20, and correspondingly providing a second limit part on the base shell 10, after the insertion block 21 is inserted into the insertion port 15, the first limit part and the second limit part are used to press against each other, so that the insertion and limiting of the insertion block 21 and the insertion port 15 are achieved, the stability of the insertion is improved, and the use process of the base is more stable.
[0031] Furthermore, in order to prevent the connection seat 20 from being detached after being inserted into the insertion slot, a limiting notch 211 can be provided on the side of the insertion block 21, and a corresponding limiting piece 151 is provided on the side wall of the insertion port 15. After the insertion block 21 is inserted into the insertion port 15, the connection seat 20 can be rotated. Since the side of the insertion block 21 is provided with a limiting notch 211, and the side wall of the insertion slot is provided with a limiting piece 151, when the connection seat 20 is rotated, the limiting piece 151 on the side wall of the insertion slot can be inserted into the limiting notch 211. After the limiting piece 151 is inserted into the limiting notch 211, the insertion block 21 can be prevented from being detached from the insertion slot, and the insertion structure is more stable.
[0032] Furthermore, a first limit block 22 at the bottom of the connecting seat 20 may be provided with a limit buckle corresponding to the base shell 10. The specific limit buckle has an elastic arm 11 and a second limit block 12. The elastic arm 11 is connected to the base shell 10. The elastic arm 11 can be made of a plastic sheet or a metal spring sheet in the prior art, so that the elastic arm 11 can bounce open and rebound autonomously when subjected to force.
[0033] The above-mentioned second limit block 12 is arranged at the end of the elastic arm 11, and the second limit block 12 has a pressure surface and a limit surface. When the insertion block 21 is inserted into the insertion slot, the first limit block 22 can first press the limit surface. When the connecting seat 20 rotates, the first limit block 22 slides along the pressure surface. During the sliding process, the second limit block 12 can be pressed. After the second limit block 12 is pressed, the elastic arm 11 unfolds, so that the first limit block 22 can slide to the end of the pressure surface and cross the second limit block 12 to abut against the limit surface, thereby achieving limitation.
[0034] When the elastic arm 11 is opened under pressure, the first limit block 22 abuts against the limit surface of the second limit block 12, and the elastic arm 11 can rebound, so that the first limit block 22 remains in a tightly abutted state, achieving stable limiting and not easy to disengage.
[0035] On the basis of the above structure, the first limiting block 22 is formed as a first limiting portion, and the limiting buckle is formed as a second limiting portion.
[0036] It should be noted that the above-mentioned limit buckle can be realized by using elastic buckles in the prior art.
[0037] More specifically, a hook 14 may be further provided at the end of the elastic arm 11, and a locking gap may be formed between the hook 14 and the limiting surface. After sliding over the pressure surface, the first limiting block 22 may cross the pressure surface and abut against the limiting surface, and be locked to the locking gap. The elastic arm 11 rebounds so that the first limiting block 22 remains in a locked state and is not easily detached.
[0038] Furthermore, the second limit block 12 is provided with a first inclined surface, and the first inclined surface is formed as a pressure surface, so that when the first limit block 22 slides against the first inclined surface of the second limit block 12, the force applied by the first limit block 22 can be decomposed by the first inclined surface, so that when the first limit block 22 rotates, it can press the elastic arm 11, so that after the elastic arm 11 opens, the first limit block 22 can slide to the limiting surface, and then the elastic arm 11 rebounds to maintain the limiting state.
[0039] More specifically, the first limiting block 22 is provided with a second inclined surface that is slidably matched with the first inclined surface, so that the inclined surfaces are slidably matched with each other, and the sliding pressing process is smoother.
[0040] Furthermore, the base housing 10 is provided with an insertion slot, and the insertion opening 15 is provided on the bottom wall of the insertion slot; the second limiting portion is provided on the insertion slot. During assembly, after the connection seat 20 is inserted into the insertion slot, the insertion block 21 of the connection seat 20 can be inserted into the insertion opening 15 of the corresponding insertion slot, so that the insertion slot can be inserted and abutted against the outer peripheral wall of the connection seat 20, and then the insertion of the insertion block 21 and the insertion opening 15 is further limited, and the insertion structure is more stable.
[0041] Furthermore, a wire threading hole 13 is provided in the middle of the insertion slot. Since the body of the electrical equipment generally needs to be wired, in order to prevent wiring confusion, after the connecting socket 20 is connected to the base shell 10, the power cord of the electrical equipment connected to the connecting socket 20 can be led out through the wire threading hole 13.
[0042] Furthermore, a plurality of reinforcing ribs are provided at the bottom end of the base shell 10. Since the base structure is used to support the main structure of the electrical equipment and needs to have a certain load-bearing performance, a plurality of reinforcing ribs are provided at the bottom end of the base shell 10 to strengthen the strength of the base shell 10 and improve the supporting performance.
[0043] Embodiment 2,
[0044] A heater comprises a heater body and the base. The bottom of the heater body can be connected to a connecting seat 20. Thus, the heater body can be used with the base as a supporting basis, and the use process is stable.
[0045] When the connection base 20 and the base shell 10 are assembled, the insertion block 21 of the connection base 20 is inserted into the insertion port 15 on the base shell 10. After the insertion, if the position is limited, it is easy to be separated under the action of external force. Therefore, in this embodiment, by further providing a first limit part on the connection base 20, and correspondingly providing a second limit part on the base shell 10, after the insertion block 21 is inserted into the insertion port 15, the first limit part and the second limit part are used to press against each other, so that the insertion and limiting of the insertion block 21 and the insertion port 15 are achieved, the stability of the insertion is improved, and the use process of the base is more stable.
[0046] Of course, the heater body and the connection seat 20 can be assembled by bolts, or by providing a threaded connection head on the connection seat 20, and correspondingly providing a threaded connection groove on the heater body, and directly performing threaded connection assembly. Alternatively, a plug-in column can be directly provided at the bottom of the heater body, and a slot can be provided on the connection seat 20, and the plug-in connection can be achieved by plugging the plug-in column into the slot. The selection is made according to actual needs.
[0047] The technical means disclosed in the solution of the utility model are not limited to the technical means disclosed in the above-mentioned implementation mode, but also include technical solutions composed of any combination of the above technical features. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model, and these improvements and modifications are also regarded as the protection scope of the utility model.
