The limiting portion 21 protrudes out of the lock sleeve 1 through the first opening 11, corresponds to the locking position of the lock assembly 100, and pushes the elastic clamping member 2 through the pushing member 3, so that the limiting portion 21 corresponds to the unlocking position of the lock assembly 100 when moving to the inner side of the lock sleeve 1. Like this, when hasp subassembly 100 is used in domestic appliance 200, for example in the garment steamer, for example telescopic link assembly 20 cup joints in the hasp cover 1 outside of garment steamer, and hasp subassembly 100 when fixing on the host computer of garment steamer, when spacing portion 21 passes through first opening 11 protrusion outside hasp cover 1 and blocks and hang on the relevant position of telescopic link assembly 20 and host computer, can realize the position locking of telescopic link assembly 20 and host computer, when bulldozing piece 3, make spacing portion 21 remove to hasp cover 1 inboard, can accomplish the position unblock of telescopic link assembly 20 and host computer, compare with telescopic link assembly 20 and host computer need be through the condition of continuous rotation operation and fixing among the prior art, easy operation, convenient to detach, and when the dismouting number of times is more, also do not have the problem that the screw-thread fit among the prior art is invalid easily, product life is higher.

In fig. 1, the sliding direction of the pushing member 3 is indicated by letter H, the direction perpendicular to the sliding direction of the pushing member 3 is indicated by letter R,

specifically, the lock sleeve 1 may be a sleeve-like structure with a hollow interior, and at least a part of the pushing member 3, the elastic locking member 2, and the like may be accommodated therein. When the pushing element 3 slides in the locking sleeve 1, the pushing element 3 may be partially arranged in the locking sleeve 1 and partially arranged outside the locking sleeve 1, so that an external part can apply pushing force to the pushing element 3. Or the pushing element 3 may be entirely located inside the locking sleeve 1, and in this case, an external member for applying a pushing force to the pushing element 3 may be inserted into the locking sleeve 1 to apply a pushing force to the pushing element 3. In addition, the edge contour of the first opening 11 may be matched with the outer contour of the limiting portion 21, or the edge contour of the first opening 11 may be larger than the outer contour size of the limiting portion 21, so that the limiting portion 21 smoothly protrudes from the first opening 11 to the buckle sleeve 1.

It can be understood that the locking sleeve 1 is provided with a sliding slot 14, and the pushing element 3 can slide in the sliding slot 14, specifically, at least one part of the pushing element 3 can slide in the sliding slot 14, and the pushing element 3 can be prevented from being separated from the locking sleeve 1 by the mutual cooperation between the sliding slot 14 and the at least one part. As an alternative embodiment, as shown in fig. 1, the pushing element 3 is provided with a limit hook 31, and the limit hook 31 can slide in the sliding slot 14 and is hooked on the edge of the sliding slot 14.

In addition, the pushing element 3 can push the elastic locking element 2 to reciprocate, specifically, when the pushing element 3 is pushed, the elastic locking element 2 is pushed, so that the limiting portion 21 of the elastic locking element 2 retracts into the locking sleeve 1, and at this time, the locking assembly 100 is in an unlocked state. When the pushing element 3 moves upward and releases the pushing action on the elastic locking element 2, the limiting portion 21 of the elastic locking element 2 extends out of the locking sleeve 1 through the first opening 11 again under the action of the elastic force, so that the locking assembly 100 is in a locked state.

In order to make the pushing of the pushing member 3 drive the limiting portion 21 of the elastic locking member 2 to retract into the locking sleeve 1, it is considered that a first inclined guide portion 33 is provided on the pushing member 3, and a second inclined guide portion 34 is provided on the elastic locking member 2 to form an inclined fit. The cooperation of the slopes of the first slope guide 33 and the second slope guide 34 enables the elastic locking member 2 to move toward the inside of the locking sleeve 1 when the pushing member 3 is pushed downward.

Further, as shown in fig. 1, the locking sleeve 1 is provided with a first partition wall 12, the first partition wall 12 is provided with at least one first limiting groove 122, and the first inclined plane guide portion 33 partially penetrates through the first partition wall 12 and/or the second inclined plane guide portion 34 partially penetrates through the first partition wall 12. By making the partial structures of the first inclined guide 33 or the second inclined guide 34 pass through the first partition wall 12, that is, fit with each other through the first stopper groove 122, the first partition wall 12 does not interfere with the movement of the first inclined guide 33 or the second inclined guide 34, and in addition, the movement of the first inclined guide 33 and the second inclined guide 34 can be stopped and guided by the first stopper groove 122. Either a partial structure of the first guide portion is fitted through the first partition wall 12 to the second slope guide portion 34, a partial structure of the second slope guide portion 34 is fitted through the first partition wall 12 to the first slope guide portion 33 located above, or a partial structure of the first slope guide portion 33 is passed through the first partition wall 12 and a partial structure of the second slope guide portion 34 is also passed through the first partition wall 12 and the first slope guide portion 33 and the second slope guide portion 34 are fitted to each other.

Furthermore, the first partition wall 12 may be arranged parallel to the bottom surface of the shackle 1, the first partition wall 12 extending, for example, in a horizontal direction. For the forming mode of the first limiting groove 122, the outer edge of the first partition wall 12 close to the guide sleeve is locally recessed to form a notch, and the notch and the inner wall of the lock sleeve 1 can form the first limiting groove 122.

In addition, in order to ensure that the displacement of the second inclined guide portion 34 in the extending direction of the elastic locking member 2 is not limited by the first limiting groove 122, alternatively, as shown in fig. 1, the dotted line is a schematic view when the elastic locking member 2 is located at the innermost side of the shackle 1, and the maximum lateral displacement L1 caused by the relative movement of the first inclined guide portion 33 and the second inclined guide portion 34 is not greater than the length L2 of the first limiting groove 122.

Further, the first inclined plane guide portion 33 includes a sliding surface 333, the first limiting groove 122 includes a first end 123 and a second end 124, and the first end 123 of the first limiting groove 122 is in sliding fit with the sliding surface 333. With this arrangement, it is ensured that the first end 123 of the first stopper groove 122 stops and guides the movement of the first inclined guide portion 33.

As a possible implementation of the specific formation structure of the first inclined plane guide part 33, as shown in fig. 1 and 3, at least two first limiting grooves 122 are arranged in parallel on the first partition wall 12, the first inclined plane guide part 33 includes at least two inclined plane guide pieces 330, and the inclined plane guide pieces 330 respectively pass through the first limiting grooves 122 to be matched with the second inclined plane guide part 34. At this time, the two inclined guide pieces 330 are required to be spaced apart from each other to form an escape space between the two inclined guide pieces 330, so that when the pushing member 3 slides along the inner wall of the shackle sleeve 1, the two inclined guide pieces 330 straddle the two sides of the first partition wall 12, and therefore the first partition wall 12 does not interfere with the movement of the pushing member 3. Further, the lower surfaces of the two slant guide pieces 330 may be formed as slant surfaces to be engaged with the second slant guides 34.

As a possible embodiment of the specific formation structure of the second inclined plane guide portion, as shown in fig. 1 and 3, the upper portion of the elastic latching portion is formed with two second inclined planes 334 which are disposed in one-to-one correspondence with the two inclined plane guide pieces 330 so as to be engaged with the lower surfaces of the two inclined plane guide pieces 330. At this time, the lower surfaces of the two slant guides 330 may be extended to pass through the first partition wall 12, and/or the lower surfaces of the two second slant guides 334 may be passed through the first partition wall 12 to achieve the engagement of the lower surfaces of the slant guides 330 and the second slant guides 334. Here, the second inclined surface 334 is inclined with respect to the vertical direction toward the direction away from the first opening 11, specifically, the second inclined surface 334 faces to the left side in fig. 1, that is, the second inclined surface 334 is formed as an inclined surface away from the first opening 11. In addition, a separation part 343 may be provided on the second inclined guide part 34 corresponding to the two inclined guide pieces, and the position of the separation part 343 corresponds to the interval between the two inclined guide pieces 330, so that when the pushing member 3 slides downward and the first inclined guide part 33 and the second inclined guide part 34 slide relatively, the two inclined guide pieces 330 straddle both sides of the separation part 343 to prevent the elastic locking member 2 from shaking and falling left and right.

Illustratively, when the pushing member 3 is assembled in the lock sleeve 1, the first inclined guide part 33 and the second inclined guide part 34 are at least partially in structural contact, so that the first inclined guide part 33 pushes the second inclined guide part 34.

As shown in fig. 2, a second partition wall 13 parallel to the first partition wall 12 is further provided inside the lock sleeve 1, and a space for accommodating the elastic locking member 2 is formed between the second partition wall 13 and the first partition wall 12. The surfaces of the first partition wall 12 and the second partition wall 13 facing each other form a slide passage for the elastic stopper 2 to slide. It will be understood that it is necessary that the surfaces of the first partition wall 12 and the second partition wall 13 which face each other are formed parallel to the bottom surface of the shackle sleeve 1. Of course, the first partition wall 12 may form the sliding channel together with the bottom wall of the shackle 1 in the case where the second partition wall 13 is not provided.

Optionally, at least one of the first partition wall 12 and the second partition wall 13 is provided with a rib 121 which is matched with the elastic blocking member 2 in the sliding direction. Thus, when the elastic stopper 2 slides along the slide chamber formed by the first partition wall 12 and the second partition wall 13, the frictional force between the surface of the elastic stopper 2 and the first partition wall 12 and the second partition wall 13 can be reduced.

In addition, as shown in fig. 2, optionally, a first guiding column 61 is disposed on a side wall of the lock sleeve 1, the elastic locking member 2 includes a first elastic member 6 and a locking member 7, and the first elastic member 6 is connected between the first guiding column 61 and the locking member 7. By arranging the first elastic element 6, when the pushing element 3 releases the pushing of the elastic clamping element 2, the limiting part 21 of the elastic clamping element 2 extends out of the lock sleeve 1 through the first opening 11, and the locking state is maintained.

Furthermore, the position-locking member 7 is provided with a first receiving groove 22 for at least partially receiving the first elastic member 6. This makes it possible to accommodate part of the structure of the first elastic element 6 in the detent element 7, in order to reduce the size of the elastic detent element 2 in its direction of extension. Meanwhile, the first receiving groove 22 can also guide and limit the elastic deformation of the first elastic element 6.

In addition, optionally, the locking assembly 100 further includes a second elastic member 5, the first partition 12 is provided with a second guiding column 51, and the second elastic member 5 is connected between the second guiding column 51 and the pushing member 3. Thus, after the pushing force of the pusher 3 is released, the pusher 3 can return the pusher 3 by the elastic force of the second elastic member 5. The second elastic member 5 may be a compression spring and in a compressed state, an axis of the second elastic member 5 is in the H direction so as to apply an upward force in the H direction to the urging member 3. It is understood that the second guide posts 51 may be provided on the surfaces of the pushing element 3 and the first partition wall 12 facing each other, the two ends of the second elastic element 5 are connected to the second guide posts 51 on the pushing element 3 and the second guide posts 51 on the first partition wall 12, respectively, and the axial directions of the second guide posts 51 of the pushing element 3 and the second guide posts 51 of the first stopper portion 21 are along the H direction.

Further, in order to prevent the push piece 3 from being fitted reversely when it is fitted to the lock case 1, a reverse fitting prevention structure may be provided on the push piece 3. Specifically, optionally, as shown in fig. 3, a guide groove 35 is provided on the pushing element 3, and a guide protrusion capable of being inserted into the guide groove 35 is provided on the inner wall of the lock sleeve 1 corresponding to the guide groove 35, so that when the pushing element 3 is assembled to the lock sleeve 1, the guide groove 35 and the guide protrusion are aligned, and the guide protrusion is inserted into the guide groove 35, thereby preventing the reverse assembly. Further, the extending direction of the guide groove 35 and the guide projection may be made along the sliding direction of the pushing member 3. Besides the above manner, a guide protrusion may be provided on the pushing element 3, and a guide groove 35 capable of receiving the guide protrusion is provided on the inner wall of the locking sleeve 1 corresponding to the guide protrusion, which is similar to the above principle, and will not be described herein again.

The operation of the locking assembly 100 of the present embodiment will now be described. As shown in fig. 1, the position-limiting portion 21 protrudes out of the first opening 11 of the lock catch sleeve 1, corresponding to the locking state of the lock catch assembly 100, at this time, the second elastic member 5 pushes the pushing member 3 to the top, the position-limiting hook 31 is hooked on the upper edge of the sliding slot 14, so as to prevent the pushing member 3 from coming off the lock catch sleeve 1, at this time, the pushing member 3 does not act on the elastic latching member 2, and the position-limiting portion 21 protrudes out of the first opening 11 under the elastic force of the first elastic member 6 of the elastic latching member 2. When an operator wants to release the locked state, the operator only needs to push the pushing element 3 downwards, the pushing element 3 overcomes the elastic force of the second elastic element 5 to displace downwards, the first inclined guide part 33 and the second inclined guide part 34 slide relatively, the elastic clamping element 2 overcomes the elastic force of the first elastic element 6 and slides in the sliding cavity to the locking sleeve 1, until the limiting element retracts into the locking sleeve 1, and the locking assembly 100 is in the unlocked state.

In this embodiment, the limiting portion protrudes out of the lock sleeve through the first opening, and corresponds to the locking position of the lock assembly, and the pushing member pushes the elastic clamping member, so that the limiting portion corresponds to the unlocking position of the lock assembly when moving to the inner side of the lock sleeve. Like this, the hasp subassembly is applied to domestic appliance, for example when in the garment steamer, for example telescopic link assembly 20 cup joints in the hasp cover 1 outside of garment steamer, and hasp subassembly 100 when fixing on the host computer of garment steamer, spacing portion 21 through first opening 11 protrusion outside hasp cover 1 and card hang when the relevant position of telescopic link assembly 20 and host computer, can realize the position locking of telescopic link assembly 20 and host computer, bulldoze piece 3 when bulldozing, make spacing portion 21 remove when hasp cover 1 is inboard, can accomplish the position unblock of telescopic link assembly 20 and host computer, moreover, the operation is simple, easy to detach, and when the dismouting number of times is more, also there is not the problem that the screw-thread fit among the prior art is inefficacy easily, product life is higher.

The specific structure, function and operation principle of the locking assembly 100 have been described in detail in the first embodiment, and are not described herein again.

In the above scheme, the locking assembly 100 is fixedly installed at the bottom of the installation hole 80, the telescopic rod assembly 20 is inserted into the installation hole 80 and sleeved outside the locking assembly 100, and at this time, the limiting portion 21 in the locking assembly 100 passes through the second opening 23 and is clamped and hung at the lower end of the second opening 23 to complete the locking of the locking assembly 100. When bulldozing piece 3, make spacing portion 21 remove when hasp cover 1 is inboard, can accomplish the position unblock of telescopic link subassembly 20 and carrier 60, compare with telescopic link subassembly 20 and the condition that carrier 60 need be fixed through continuous rotation operation among the prior art, easy operation, convenient to detach to when the dismouting number of times is more, also there is not the problem that the screw-thread fit among the prior art became invalid easily, product life is higher.

In addition, when the telescopic rod assembly is specifically installed, one installation hole 80 corresponds to one locking component 100 and one telescopic rod assembly 20, namely, the installation holes are installed in a one-to-one correspondence mode, or one installation hole 80 corresponds to a plurality of locking components 100 and one telescopic rod assembly 20, and the transformation can be carried out.

Further, in this embodiment, the household appliance 200 may be an appliance that is often used in daily life, for example, the household appliance 200 may be a garment steamer, and the carrier 60 may be a main machine, in this case, the garment steamer includes the ironing head assembly 30, the upper cover 40, and the drying cover 50 in addition to the main machine and the telescopic rod assembly 20. One end of the drying cover 50 is connected with the upper cover 40, and the other end is fixed at the upper end of the main machine 60, so that the upper cover 40, the drying cover 50 and the main machine 60 together form a drying chamber for drying clothes, and the ironing head assembly 30 is connected with the main machine 60 to iron the clothes.

The latch assembly 100 may be secured to the host 60 as shown in fig. 5. Fig. 6 is a cross-sectional view of the household appliance provided by the second embodiment of the present invention in the first state; fig. 7 is a cross-sectional view of the household appliance provided by the second embodiment of the present invention in a second state; fig. 8 is a partial cross-sectional view of the household appliance in the second state according to the second embodiment of the present invention; fig. 9 is a schematic structural diagram of a pressing block in a household appliance provided in the second embodiment of the present invention; fig. 10 is a schematic structural view of a sleeve in a household appliance according to an embodiment of the present invention.

Optionally, as shown in fig. 6, 7, and 8, the telescopic rod assembly 20 includes a first telescopic rod 25 and a hollow second telescopic rod 26, the first telescopic rod 25 can slide inside the second telescopic rod 26 to extend and retract the telescopic rod assembly 20, a pressing block 27 is disposed at a bottom end of the first telescopic rod 25, and the pressing block 27 is configured to push the pushing element 3 to move toward a direction close to the elastic clamping element 2 when the telescopic rods extend and retract. When the lock of the lock catch assembly 100 is to be released, the first telescopic rod 25 is slid downward along the inside of the second telescopic rod 26, and the pressing piece 27 is pushed against the pushing piece 3, so that the stopper 21 can be retracted from the second opening 23 into the lock catch 1, thereby unlocking the telescopic rod assembly 20 and the main unit 60. Of course, a third section of the telescopic rod 28 may be further disposed on the first section of the telescopic rod 25, as shown in fig. 4, the third section of the telescopic rod 28 can slide inside the first section of the telescopic rod 25, and therefore, when the telescopic rod assembly 20 includes three sections of telescopic rods, it is considered that the third section of the telescopic rod 28 slides inside the first section of the telescopic rod 25 first, and then the first section of the telescopic rod 25, which contains the third section of the telescopic rod 28 therein, slides inside the second section of the telescopic rod 26, so as to achieve the extension and retraction of the telescopic rod assembly 20.

The pressing piece 27 has a specific structure as shown in fig. 9, and the bottom is formed flat so as to be in contact with the tip of the pushing member 3 to apply a force to the pushing member 3.

Further, as shown in fig. 8 and 10, a sleeve 29 is fixedly connected to the inside of the bottom end of the second telescopic rod 26, the inner diameter of the sleeve 29 is greater than or equal to the outer diameter of the locking assembly 100, a limiting wall 291 is provided at an end portion of the sleeve 29 close to the first telescopic rod 25, and a through hole 292 through which an end portion of the pushing element 3 passes is provided on the limiting wall 291. A third opening 293 is provided in the sleeve 29 at a position corresponding to the stopper 21 for the stopper 21 to pass through. The sleeve 29 is fixed to the bottom end of the second telescopic rod 26, so that the limiting wall 291 can limit the downward movement of the first telescopic rod 25, and the end of the pushing element 3 extends above the sleeve 29 through the through hole 292, so that the pressing block 27 can push the end of the pushing element 3 when the first telescopic rod 25 moves downward.

Here, the end of the pushing element 3 may be formed as a constricted portion 36 with a partially reduced size, and the diameter of the through hole 292 may be matched with the outer size of the constricted portion 36, so that the constricted portion 36 can enter the inside of the second telescopic rod 26 from the through hole 292.

Further, the outer edge profile of the second opening 23 is smaller than the outer edge profile of the first opening 11. When the size of the first opening 11 is large enough not to limit the position of the detent 2, the wall of the second section of the limiting rod can stop the detent 2 when the locking assembly 100 is sleeved inside the second section of the limiting rod, so as to prevent the detent 2 from being released from the locking sleeve 1. The construction of the press piece 27 and the sleeve 29 has been described above by way of example with the catch assembly 100 secured in the carrier 60. But similarly, the locking assembly 100 is secured to the pole assembly 20 and will not be expanded in detail.

In addition, optionally, when the locking assembly 100 is fixed inside the mounting hole 80, it is considered that the mounting hole 80 further has a first supporting surface therein, and the first supporting surface is used for supporting the bottom end of the second telescopic rod 26, that is, when the telescopic rod assembly 20 is inserted into the mounting hole 80, the bottom end of the second telescopic rod 26 abuts against the first supporting surface. The first bearing surface here may be formed by a stepped hole, specifically, a stepped hole whose stepped surface in the radial direction thereof forms the first bearing surface is formed in the mounting hole 80. Specifically, a gap is formed between the outer wall of the lock sleeve 1 and the inner surface of the mounting hole 80, the bottom of the second section of the telescopic rod 26 can be inserted into the gap, and the bottom of the second section of the telescopic rod 26 can be just supported on the first supporting surface.

Optionally, the end of the latch sleeve 1 away from the pushing element 3 is bent outward to form an assembly groove 15, the notch of the assembly groove 15 faces the pushing element 3, an installation portion 16 matched with the assembly groove 15 is arranged on the end face of the installation hole 80, and the latch assembly 100 is sleeved on the installation portion 16 through the assembly groove 15 and fixed on the bearing element 60.

In addition, in the case where the locking catch assembly 100 shown in fig. 8 is fixed to the carrier 60, the surface of the stopper portion 21 that abuts the lower end of the second opening 23 extends in the protruding direction of the stopper portion 21. In this way, in the process of lifting up the telescopic link assembly 20, the surface of the limiting portion 21 abutting against the lower end of the second opening 23 can be hooked on the lower end of the second opening 23 of the telescopic link assembly 20, and the telescopic link assembly 20 can be prevented from coming out of the mounting hole 80.

Specifically, the surface 211 of the limiting portion 21 facing away from the pushing element 3 is a plane extending along the protruding direction of the limiting portion 21, i.e. a horizontally disposed plane, because when the locking sleeve 1 is fixed in the mounting hole 80 of the bearing element 60, the limiting portion 21 is hooked in the second opening 23, when the operator needs to move the position of the garment steamer, e.g. grasp the telescopic rod assembly 20, and lift the bearing element 60, the second section of telescopic rod 26 has a tendency to disengage from the bearing element 60, and at this time, the surface 211 of the limiting portion 21 facing away from the pushing element 3 is hooked on the lower edge of the second opening 23, and if the surface 211 of the limiting portion 21 facing away from the pushing element 3 is disposed parallel to the bottom of the locking sleeve 1, the force applied to the surface 211 is perpendicular to the force applied to the second section of telescopic rod 26, so that the second section of telescopic rod 26 can be prevented from disengaging from the bearing element 60. Of course, the hole wall of the mounting hole 80 may be provided with a second limiting groove 81 at a position corresponding to the second opening 23.

Next, taking the case that the locking assembly 100 shown in fig. 6 and 7 is disposed on the carrier 60 as an example to describe the assembling and disassembling process of the household appliance 200 of the present embodiment, as shown in the first state shown in fig. 6, the limiting portion 21 protrudes out of the first opening 11 and the second opening 23, and is hooked in the second limiting groove 81, corresponding to the locking state of the second telescopic rod 26 and the carrier 60. At this time, the second elastic element 5 pushes the pushing element 3 to the uppermost end, the necking part 36 penetrates out of the through hole 292, the upper part of the pushing element 3 is also abutted against the limiting wall 291, and the limiting hook 31 is clamped and hung on the upper edge of the sliding groove 14, so that the pushing element 3 can be prevented from being separated from the locking sleeve 1, at this time, the pushing element 3 does not act on the elastic clamping element 2, the limiting part 21 protrudes out of the first opening 11 and the second opening 23 under the elastic force of the first elastic element 6 of the elastic clamping element 2. When an operator wants to release the locked state, the operator only needs to move the first section of telescopic rod 25 downwards to make the pressing block 27 push the pushing element 3 downwards, the pushing element 3 overcomes the elastic force of the second elastic element 5 to displace downwards, the first guiding inclined plane 33 and the second guiding inclined plane 34 slide relatively, the elastic clamping element 2 overcomes the elastic force of the first elastic element 6 and slides in the sliding cavity into the locking sleeve 1 until the limiting element retracts into the locking sleeve 1, and at this time, the telescopic rod assembly 20 can be taken out from the mounting hole 80, so that the telescopic rod assembly 20 and the host 60 can be detached. The installation process for the telescopic rod assembly 20 and the main machine 60 is similar, and will not be described in detail here.
