Description

Technical Field

[0001] The utility model relates to the technical field of push-rod vacuum cleaners, in particular to a handle structure and a push-rod vacuum cleaner. Background Art

[0002] At present, most of the push-rod vacuum cleaner handle structures on the market are as follows:

[0003] 1) The connection method of connecting the main body and the handle with a screw stud: The handle and the main body are directly connected together with a stud. After the vacuum cleaner is used for cleaning, the handle cannot be folded up directly. Instead, the stud must be loosened with a tool, which is extremely inconvenient to use.

[0004] 2) Knob-type handle structure: It uses a side knob-type switch, which is mostly a two-point fixed structure. The installation is complicated and not firm. The knob-type switch is also not convenient to use.

[0005] 3) Connecting rod movable buckle type lock folding structure: The handle releases the buckle connecting rod installed on the handle by pressing a button to release the folding handle. This structure has insufficient strength and the force of the entire product is concentrated on the connecting rod. The connecting rod is prone to breakage and failure, and the swing of the product during use is prone to disengagement.

[0006] The Chinese utility model patent with authorization announcement number CN208784600U discloses a vacuum cleaner with a foldable body. The handle of the prior art can be folded relative to the body assembly to facilitate the storage of the vacuum cleaner body; however, the lock hook structure of the prior art is very complicated, including a first lock part, a second lock part and a third lock part arranged from top to bottom, the first lock part is hinged on the handle, the second lock part is connected to the first lock part at an obtuse angle, the third lock part is connected to the second lock part at a right angle, and the lock hook is hinged on the handle, so that its bite force is subjected to force along the tangent direction of the circle through a fulcrum. When in use, the lock buckle is always subjected to tangential force and is easily disengaged.

[0007] Therefore, there is still room for improvement and development in the existing technology. Utility Model Content

[0008] In response to the problems of the existing technology, the utility model provides a handle structure and a push-rod vacuum cleaner, in which the handle can be folded or unfolded relative to the main body, making it easy to use; when the handle is unfolded relative to the main body, the pin is vertically inserted into the slot and locked, so that the force is applied in the up and down directions. When the pin is vertically inserted into the slot, the handle and the main body can be locked with each other and will not come loose.

[0009] In order to achieve the above-mentioned purpose, the technical solution applied by the present utility model is as follows:

[0010] A handle structure includes a handle and a body, the handle and the body being hingedly connected and foldable relative to the body. A locking mechanism is provided between the handle and the body. When the handle and the body are unfolded, the inner end surface of the handle corresponds to and abuts the outer end surface of the body, locking the locking mechanism. When the locking mechanism is unlocked, the handle and the body can be folded, and the inner end surface of the handle corresponds to and separates from the outer end surface of the body. This arrangement allows the handle to be folded or unfolded relative to the body, making it convenient to use.

[0011] According to the above solution, the locking mechanism includes a pin movably disposed within the handle and a slot fixedly disposed on the main body, the pin and slot being positioned correspondingly. When the handle is extended relative to the main body, the pin engages vertically into the slot and locks the handle. The pin is then driven out of the slot by a drive assembly. This arrangement allows the pin to engage vertically into the slot and lock the handle when the handle is extended relative to the main body, resulting in a vertical force applied. When the pin engages vertically into the slot, the handle and main body are locked together, preventing disengagement.

[0012] According to the above solution, a guide groove is provided within the handle, and a latch is slidably disposed within the guide groove. Multiple elastic members are fixed within the guide groove, and the multiple elastic members abut or are fixed to the latch. When the handle is unfolded relative to the main body, the latch engages and locks into the latch groove due to the elastic force of the multiple elastic members. The latch is driven up and down within the guide groove by a drive assembly to disengage the latch, and the guide groove is provided with a guide assembly that allows the latch to be vertically raised and lowered. With this arrangement, when the handle is unfolded relative to the main body, the latch engages and locks vertically within the latch groove under the elastic force of the multiple elastic members, and the handle cannot be folded relative to the main body. Furthermore, under the action of the guide assembly, the drive assembly drives the latch to vertically raise and lower within the guide groove.

[0013] According to the above solution, the guide assembly includes a plurality of guide posts fixed vertically in the guide slots, and the bayonet is provided with a plurality of guide holes, the guide posts being slidably connected to the guide holes. This arrangement enables the bayonet to be lifted and lowered vertically along the guide posts.

[0014] According to the above solution, the elastic member includes a supporting spring, which is sleeved on the guide post of the guide assembly. In this way, the supporting spring is limited by the guide post so that the supporting spring is stable when compressed and released.

[0015] According to the above solution, the drive assembly includes a release button on the handle, one end of which extends into the guide slot and abuts or is fixed to the latch. In this arrangement, when the handle is folded relative to the main body, pressing the release button pushes the latch, causing the latch to disengage the slot, and the handle can now be folded relative to the main body.

[0016] According to the above solution, a limit seat is fixed to the opening of the guide slot, and one end of the release key passes through the limit seat and abuts against the latch. This arrangement allows the limit seat to be used to limit the latch pin's position within the guide slot and to limit the latch pin's position at the opening of the guide slot when it is raised. In actual use, the limit seat and the guide post are fixed by fixing bolts, and both the limit seat and the guide post are provided with screw holes that mate with the fixing bolts.

[0017] According to the above solution, the release button is formed with a driving rod, the limit seat is formed with a slot, and the bayonet is formed with a transmission post. The driving rod passes through the slot and abuts the transmission post. In this arrangement, when the release button is pressed, the driving rod passes through the slot and abuts the transmission post, thereby driving the bayonet to descend and disengage from the slot. When the release button is released, the elastic member pushes the bayonet, and the transmission post passes through the slot and abuts the driving rod, thereby driving the release button to reset.

[0018] According to the above solution, the stopper seat is formed with a perforation, and the latch pin is formed with a latching post, which is positioned corresponding to the perforation. With this arrangement, when the handle is extended relative to the main body, the latch pin is raised under the elastic force of the multiple elastic members. The latching post on the latch pin passes through the perforation and vertically engages with the latching slot to lock, while the stopper seat simultaneously restrains the latch pin. In actual use, the latching post is positioned vertically on the latch pin.

[0019] According to the above solution, a retaining plate extends from the outer end surface of the main body, a retaining slot is provided on the retaining plate, and a hole is provided on the inner end surface of the handle corresponding to the retaining plate. This arrangement allows the retaining plate to extend into the hole and engage with the retaining pin to lock the handle when the handle is extended relative to the main body. In actual use, when the handle is extended relative to the main body, the inner end surface of the handle aligns with the outer end surface of the main body, and the retaining plate and retaining pin form a concealed lock structure, resulting in a more aesthetically pleasing appearance.

[0020] According to the above solution, the handle includes an upper handle cover and a lower handle cover, which are fixedly connected; the main body includes an upper handle cover and a lower handle cover, which are fixedly connected; the lower handle cover and the lower handle cover are hingedly connected via a rotating shaft, and the upper handle cover and the upper handle cover are detachably connected via a locking mechanism.

[0032] The technical solution of the present utility model is described below with reference to the accompanying drawings and embodiments.

[0033] like Figures 1 to 6As shown, the handle structure of the present invention includes a handle 20 and a main body 30. The handle 20 is hingedly connected to the main body 30 and can be folded or unfolded relative to the main body 30. A locking mechanism is provided between the handle 20 and the main body 30. When the handle 20 and the main body 30 are unfolded, the inner end surface 16 of the handle 20 is aligned with the outer end surface 17 of the main body 30, and the locking mechanism is locked. After the locking mechanism is unlocked, the handle 20 and the main body 30 can be folded, and the inner end surface 16 of the handle 20 is separated from the outer end surface 17 of the main body 30. This arrangement allows the handle 20 to be folded or unfolded relative to the main body 30, making it convenient to use. In actual application, the end of the handle 20 closest to the main body 30 is the inner end, and the end of the main body 30 closest to the handle 20 is the outer end.

[0034] More specifically, the locking mechanism includes a latch 4 movably disposed within the handle 20 and a slot 100 fixedly disposed on the body 30. The latch 4 and slot 100 are correspondingly disposed. When the handle 20 is extended relative to the body 30, the latch 4 vertically engages and locks within the slot 100. The latch 4 is driven by a drive assembly to disengage the slot 100. This arrangement allows the latch 4 to vertically engage and lock within the slot 100 when the handle 20 is extended relative to the body 30, resulting in a vertical force applied. When the latch 4 vertically engages the slot 100, the handle 20 and body 30 are locked together, preventing disengagement.

[0035] In this embodiment, the handle 20 is provided with a guide slot 13, and the latch 4 is slidably disposed within the guide slot 13. Multiple elastic members are fixed within the guide slot 13, and the multiple elastic members abut or are fixed to the latch 4. When the handle 20 is unfolded relative to the body 30, the latch 4 engages and locks into the slot 100 due to the elastic force of the multiple elastic members. The latch 4 is driven to rise and fall within the guide slot 13 by a drive assembly, thereby disengaging the latch 4 from the slot 100. The guide slot 13 is provided with a guide assembly that allows the latch 4 to be vertically raised and lowered. This arrangement allows the handle 20 to be unfolded relative to the body 30, and the latch 4 engages and locks vertically within the slot 100 due to the elastic force of the multiple elastic members. At this point, the handle 20 cannot be folded relative to the body 30. Furthermore, the drive assembly drives the latch 4 to vertically rise and fall within the guide slot 13 under the action of the guide assembly.

[0036] More specifically, the guide assembly includes a plurality of guide posts 12 vertically fixed in guide slots 13, and the bayonet 4 is provided with a plurality of guide holes 43, the guide posts 12 being slidably connected to the guide holes 43. This arrangement allows the bayonet 4 to be vertically lifted along the guide posts 12 when it is lifted.

[0037] In this embodiment, the elastic member includes a support spring 6, which is sleeved on a guide post 12 of the guide assembly. In this way, the support spring 6 is limited by the guide post 12 so that the support spring 6 is stable when compressed and released.

[0038] In this embodiment, the drive assembly includes a release button 3 on the handle 20. One end of the release button 3 extends into the guide slot 13 and abuts against the latch 4. With this arrangement, when the handle 20 is folded relative to the main body 30, pressing the release button 3 pushes the latch 4 to move, causing the latch 4 to disengage from the slot 100, allowing the handle 20 to fold relative to the main body 30.

[0039] In this embodiment, a limit seat 5 is fixed to the opening of the guide slot 13. One end of the release button 3 passes through the limit seat 5 and abuts against the latch 4. This arrangement allows the limit seat 5 to prevent the latch 4 from being located within the guide slot 13 and to prevent the latch 4 from being located at the opening of the guide slot 13 when it is raised. In practice, the limit seat 5 and the guide post 12 are secured by fixing bolts 7. Both the limit seat 5 and the guide post 12 are provided with screw holes that mate with the fixing bolts 7.

[0040] In this embodiment, the release button 3 is formed with a driving rod 31, the limiting seat 5 is formed with a slot 51, and the latch pin 4 is formed with a transmission post 41. The driving rod 31 passes through the slot 51 and abuts against the transmission post 41. In this arrangement, when the release button 3 is pressed, the driving rod 31 passes through the slot 51 and abuts against the transmission post 41, thereby driving the latch pin 4 to descend and disengage from the slot 100. When the release button 3 is released, the elastic member pushes the latch pin 4 to actuate, and the transmission post 41 passes through the slot 51 and abuts against the driving rod 31, thereby driving the release button 3 to return to its original position.

[0041] In this embodiment, the stopper seat 5 is formed with a through-hole 52, and the latch 4 is formed with a latch post 42, with the latch post 42 corresponding to the through-hole 52. With this arrangement, when the handle 20 is extended relative to the body 30, the latch 4 is raised under the elastic force of the multiple elastic members. The latch post 42 on the latch 4 passes through the through-hole 52 and vertically engages with the latch slot 100, locking the latch 4. Simultaneously, the stopper seat 5 limits the position of the latch 4. In actual use, the latch post 42 is vertically located on the latch 4.

[0042] In this embodiment, a retaining plate 14 extends from the outer end surface 17 of the body 30, a retaining groove 100 is provided on the retaining plate 14, and a hole 15 is provided on the inner end surface 16 of the handle 20, corresponding to the retaining plate 14. This arrangement allows the retaining plate 14 to extend into the hole 15 and engage with the bayonet 4 to lock the handle 20 when the handle 20 is extended relative to the body 30. In actual use, when the handle 20 is extended relative to the body 30, the inner end surface 16 of the handle 20 and the outer end surface 17 of the body 30 are aligned, and the retaining plate 14 and the bayonet 4 form a concealed lock structure, resulting in a more aesthetically pleasing appearance.

[0043] In this embodiment, the handle 20 includes an upper handle cover 1 and a lower handle cover 2, which are fixedly connected. The main body 30 includes an upper handle cover 10 and a lower handle cover 11, which are fixedly connected. The lower handle cover 2 and the lower handle cover 11 are hingedly connected via a rotating shaft 40, and the upper handle cover 1 and the upper handle cover 10 are detachably connected via a locking mechanism. In actual application, the lower handle cover 2 and the lower handle cover 11 are each provided with a connecting column with a hole, and the two connecting columns are hingedly connected via the rotating shaft 40 after being aligned. The rotating shaft 40 includes a rotating shaft 1 8 and a rotating shaft 2 9, which are assembled together to form the rotating shaft 40.
