Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present utility model, "a plurality" means two or more unless otherwise specifically defined.

[0031] Please refer to Figures 1 to 3 , the present utility model provides a handle structure 100 for a ventilator, which includes a main unit 11 and a handle 12 assembled on the main unit 11. The main unit 11 is provided with two insertion slots 112 arranged at intervals along the top plane. Two nuts 1121 are respectively built in the two insertion slots 112. Two installation slots 123 are respectively opened at both ends of the handle 12. A screw 124 is installed in each installation slot 123, and an avoidance hole for passing through the threaded portion of the screw 124 is opened at the bottom of the installation slot 123. The head of each screw 124 is movably assembled in an installation slot 123, and the threaded portions of the screws 124 are respectively locked with the nuts 1121 in one-to-one correspondence.

[0032] In this embodiment, the screw 124 can be a hexagonal shoulder screw 124, and the nut 1121 can be a press riveting nut 1121. The press riveting nut 1121 has a circular shape and is provided with embossed teeth and a guiding groove at one end. The principle is that the embossed teeth are pressed into the pre-set hole position of the sheet metal. Generally, the diameter of the pre-set hole is slightly smaller than that of the embossed teeth of the press riveting nut 1121. Through pressure, the embossed teeth of the press riveting nut 1121 are squeezed into the plate, causing plastic deformation around the pre-set hole. The deformed material is squeezed into the guiding groove, thus producing a locking effect.

[0033] The screw 124 includes a screw part and a head. The screw part is provided with threads, and the diameter of the head is larger than that of the threaded part. The threaded part passes through the avoidance hole, and the head abuts against the bottom of the installation groove 123. After the screw 124 and the nut 1121 are locked, they are locked to each other. The nut 1121 will not displace within the insertion groove 112. Therefore, the locked screw 124 will not rotate either. The head of the screw 124 and the installation groove 123 are movably assembled. Therefore, as the handle 12 rotates, the peripheral wall of the installation groove 123 and the head of the screw 124 move relative to each other. Thus, friction is generated by the extrusion between the head of the screw 124 and the peripheral wall of the installation groove 123, with a certain damping effect, enabling the handle 12 to stop at a certain position during the rotation process, offsetting the influence of the self-weight of the handle 12. When the user uses the handle 12 multiple times, there is no need to repeatedly lift the handle 12, greatly improving the usage efficiency of the handle 12.

[0034] To further increase the friction between the head of the screw 124 and the inner wall of the installation groove 123, a friction member is provided on the inner wall of each installation groove 123, which is wound around the head of the screw 124. The friction member can be made of materials such as rubber and plastic. Structures for increasing friction, such as friction marks or grooves, can also be provided on the direction of the friction member facing the head of the screw 124. The larger friction can effectively support the relatively heavy handle 12, increasing the applicability of the handle 12 within different mass ranges.

[0035] In this embodiment, the two installation grooves 123 of the handle 12 are connected through the avoidance holes, that is, the screw 124 is inserted through the avoidance hole from the opening of the installation groove 123, so that the notch of the screw 124 faces the same direction as the opening of the installation groove 123. The user can insert a corresponding screwdriver into the opening of the installation groove 123 to lock the screw 124 and the nut 1121. After the locking is completed, to maintain the integration of the outer surface of the handle 12 and prevent foreign objects from entering the installation groove 123, a sealing member 125 is installed in each installation groove 123, and each sealing member 125 is used to block the opening of an installation groove 123. The sealing member 125 can be made of materials such as rubber and resin, and can be provided with a handle for facilitating the removal of the sealing member 125 during the process of disassembling and assembling the screw 124.

[0036] Please refer to Figure 4 and Figure 5, in this embodiment, the handle 12 includes a holding portion 121 and two plugging portions 122 respectively connected to both ends of the holding portion 121. An included angle exists between the extending direction of each plugging portion 122 and the extending direction of the holding portion 121. An installation groove 123 is formed at one end of each plugging portion 122 away from the holding portion 121. When the handle 12 is made of a hard material such as plastic, the provided holding portion 121 and the two plugging portions 122 can have a certain angle, so that the holding portion 121 and the two plugging portions 122 in the handle 12 assembled at the top of the main body 11 enclose a space area for the user to place the hand. The user holds the holding portion 121 to perform the lifting action using the handle 12. When the handle 12 is made of a soft material such as leather, the holding portion 121 and the two plugging portions 122 can have a certain angle or be on the same horizontal line. The user lifts the holding portion 121, causing the holding portion 121 and the two plugging portions 122 to bend naturally. And when the handle 12 hovers at different positions on the rotation path, it is beneficial for the user to use the holding portion 121.

[0037] Specifically, the opening directions of the two plugging slots 112 are arranged in opposite directions. The distance between the two installation grooves 123 is greater than the distance between the two plugging slots 112. The extending directions of the threaded portions of the two screws 124 disposed in the two installation grooves 123 are arranged relatively. In other embodiments, the distance between the two plugging portions 122 can be less than the distance between the two plugging slots 112, so that the handle 12 is clamped between the two plugging slots 112, which is not limited herein.

[0038] In this embodiment, the two plugging portions 122 are respectively perpendicular to the holding portion 121, and the two plugging portions 122 are arranged in parallel. The rotation direction of the corresponding holding portion 121 is a horizontal rotation along the extending direction of the holding portion 121. The rotation angle on the plane is smaller and more labor-saving. The two parallel plugging portions 122 maintain synchronous rotation with the same force, maintaining the use stability of the ventilator handle structure 100.

[0039] Please refer to Figure 3 , two clamping portions 111 protrude from the top of the main body 11. A plugging slot 112 is formed on each clamping portion 111. The main body 11 includes a cover body 113 assembled on the two clamping portions 111. The cover body 113 is provided with two limiting holes 1131 that are respectively communicated with the two plugging slots 112 and used for passing through the threaded portions of the two screws 124. The cover body 113 makes the top of the main body 11 integrated, covering the internal installation structure of the main body 11 and preventing foreign objects from entering the main body 11. The cover body 113 also enhances the connection relationship between the clamping portion 111 and the plugging portion 122, improving the aesthetic degree of the plugging installation of the main body 11 and the handle 12.

[0040] Please refer to Figures 9 to 10, To better install the cover 113, an installation platform 114 is correspondingly provided on the top plane of the main body 11. The installation platform 114 limits the installation area of the cover 113, and multiple reinforcing ribs are provided inside the installation platform 114 to enhance the structural strength of the top shell. Before installing the cover 113, the rivet nut 1121 needs to be riveted in the insertion slot 112 of the clamping part 111 first, and then the two clamping parts 111 with the rivet nut 1121 are inserted into the through hole of the installation platform 114. The connection relationship between the clamping part 111 and the installation platform 114 can be a detachable connection, such as insertion, clamping, screw component locking, etc. In this embodiment, the installation platform 114 is provided with screw holes for locking at the top of the shell to realize the assembly between the clamping part 111 and the shell.

[0041] The cover 113 is correspondingly provided with screw holes on the installation platform 114 for direct locking assembly. Then, the two insertion parts 122 of the handle 12 are inserted into both ends of the cover 113, and then locked tightly at both ends by two screws 124 respectively. Then, the seal 125 is inserted into the installation slots 123 at both ends of the handle 12 to complete the assembly.

[0042] In this embodiment, the handle 12 has a use position perpendicular to the top plane of the main body 11 and a storage position in contact with the top plane of the main body 11. When the handle 12 is in the storage position, part of the outer surface of the cover 113 is in contact with the inner sides of the holding part 121 and the two insertion parts 122. The cover 113 can have a certain height and is added to the top of the main body 11. There is a height difference between the cover 113 and the top plane of the main body 11. When the handle 12 is in the storage position, the handle 12 can be clamped on the periphery of the cover 113, so that the handle 12 and the cover 113 form the same plane, providing a position for fixing the handle 12. Clasps can be added to the periphery of the cover 113. When the handle 12 is in the storage position, the clasps on the cover 113 can fix the handle 12, and the handle 12 will not rotate or move in the scenario where the handle 12 is not needed.

[0043] Please refer to Figure 7 and Figure 8 , In the actual process of using the handle 12, the handle 12 only needs to rotate a fixed angle and does not need to rotate in a full circle. The rotation area with a limited fixed angle can limit the fixed storage position and use position, improving the use efficiency. To limit the rotation trajectory of the handle 12, a limiting part 1221 is protruded along the periphery of an avoidance hole on each insertion part 122, and each limiting part 1221 is assembled in a limiting hole 1131. A blocking part 1132 that abuts against a limiting part 1221 is protruded on the inner wall of each limiting hole 1131, and each blocking part 1132 is used to limit the movement trajectory of the handle 12 between the use position and the storage position.

[0044] Specifically, when the cross-sections of the insertion slot 112 and the insertion portion 122 are circular, the cross-section of the limiting portion 1221 can be formed as a sector ring. The inner circle diameter of the limiting portion 1221 is the same as the diameter of the avoidance hole. The outer circle diameter of the limiting portion 1221 is the same as the diameter of the insertion slot 112 and the diameter of the limiting hole 1131. The blocking portion 1132 in the limiting hole 1131 is also arranged as a sector ring. The inner circle diameter of the blocking portion 1132 is the same as the diameter of the avoidance hole, and is used for passing through the threaded portion of the screw 124. The outer circle diameter of the blocking portion 1132 is the same as the outer circle diameter of the limiting portion 1221. Therefore, the width of the blocking portion 1132 is the same as the width of the limiting portion 1221. By setting the arc lengths of different blocking portions 1132 and the arc lengths of the limiting portions 1221, the movement trajectories of the storage position and the use position of the handle 12 are regulated. In other embodiments, the angle between the handle 12 and the top plane of the main body 11 when the handle 12 is in the storage position can be less than or greater than 90 degrees.

[0045] In one embodiment, a placement groove is concavely provided at the top end of the main body 11. The two insertion slots 112 are arranged on two opposite side walls of the placement groove. The handle 12 has a storage position placed inside the placement groove and a use position perpendicular to the top plane of the main body 11. The distance between the two insertion slots 112 is greater than the distance between the two insertion portions 122. The placement groove concavely provided at the top end of the main body 11 can be arranged to fit the shapes of the holding portion 121 and the two insertion portions 122, so that the handle 12 can be embedded into the top plane of the main body 11, effectively saving space.

[0046] Please refer to Figure 6 , to reduce the collision between the handle 12 and the top end of the main body 11 during the rotation process, a shock-absorbing pad 126 is provided on one side of each insertion portion 122 facing the top end of the main body 11. The shock-absorbing pad 126 can be made of flexible materials such as rubber and resin. The shock-absorbing pad 126 is arranged on the insertion portion 122. When the handle 12 enters the storage position, the shock-absorbing pad 126 contacts the top plane of the main body 11 prior to the insertion portion 122 and the holding portion 121, thereby playing a shock-absorbing role. The protruding shock-absorbing pad 126 can also make a gap between the handle 12 and the outer shell of the main body 11, facilitating the use of the handle 12. Correspondingly, in other embodiments, a shock-absorbing pad 126 can also be provided on the top plane of the main body 11 for the purpose of separating the handle 12 and the main body 11 housing.

[0047] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
