That is, when the catch 300 is at the second position, the projection of the outermost point of the catch 300 on the surface of the support plate 3000 in the axial direction of the recess of the support plate 3000 is located outside the recess thereof.

Fig. 4B shows a state of the holder 1000 at a certain time during the process of penetrating the recess of the support plate 3000 along the axial direction of the recess of the support plate 3000 with the casing 2000 of the range hood, referring to fig. 4B, in this state, at least part of the buckle 300 is located in the recess of the support plate 3000, and the part of the buckle 300 is pressed by the inner groove wall of the recess of the support plate 3000, the second end of the buckle 300 is in the first position, and the width of the second end of the buckle 300 exposed at the outermost end face of the range hood is narrowed.

Fig. 4C shows a state of the holder 1000 penetrating the recess of the support plate 3000 along the axial direction of the recess of the support plate 3000, referring to fig. 4C, in this state, the second end of the buckle 300 is higher than the recess of the support plate 3000, the support plate 3000 has no extrusion effect on the buckle 300, the second end of the buckle 300 is restored from the first position to the second position, at this time, the second end of the buckle 300 can be exposed outside the outermost end face of the range hood, and the width of the second end of the buckle 300 exposed outside the outermost end face of the range hood is greater than the width between the inner groove wall of the recess of the support plate 3000 and the outermost end face of the range hood. That is, when the catch 300 is at the second position, the projection of the outermost point of the catch 300 on the surface of the support plate 3000 in the axial direction of the recess of the support plate 3000 is located outside the recess thereof. The clasp 300 is supported between the support plate 3000 and the base 100 such that the support plate 3000 can provide support for the housing 2000.

In summary, the fixer 1000 provided by the embodiment of the utility model has the advantage of being convenient for installing the embedded range hood.

Fig. 5 is a perspective cross-sectional view of the holder 1000 shown in fig. 3, and fig. 6 is an exploded view of the holder 1000 shown in fig. 3. Referring to fig. 3, 5 and 6, alternatively, the clip 300 may have elasticity, and the clip 300 may include a first portion 310 and a second portion 320. The first portion 310 may be hinged to the base 100, the second portion 320 is connected to the first portion 310 and is bent relative to the first portion 310, and a bending angle between the first portion 310 and the second portion 320 is an obtuse angle, and the bending angle gradually becomes smaller during the movement of the buckle 300 from the first position to the second position.

Specifically, when the buckle 300 moves above the support plate 3000, the buckle 300 is at the second position, and the supporting force received by the buckle 300 by the support plate 3000 is sequentially transferred to the base 100 through the second portion 320 and the first portion 310. That is, the buckle 300 is supported between the base 100 and the supporting plate 3000, and the bending portion between the first portion 310 and the second portion 320 can play a better supporting role to avoid deformation of the buckle 300.

In addition, the buckle 300 can utilize the change of the bending angle to realize the elastic change of the buckle 300. Specifically, during the process that the buckle 300 passes through the groove of the support plate 3000 in the forward direction along the second direction, the first portion 310 is first abutted against by the inner groove wall of the groove of the support plate 3000 to rotate, so that the second portion 320 moves towards the base 100, and the overall lateral width of the buckle 300 is reduced. The connection of the first portion 310 and the second portion 320 is the most protruding position of the entire clasp 300, and when the connection is abutted by the inner groove wall of the groove of the support plate 3000, the bending angle between the first portion 310 and the second portion 320 increases from the initial angle. When the second portion 320 is positioned above the support base, the bent angle between the first portion 310 and the second portion 320 is reduced to an initial angle. In addition, the bent angle forming the obtuse angle has the advantages of good stability and high reliability compared with other angles.

Further, the second portion 320 may extend along the axial direction of the recess of the support plate 3000 when the buckle 300 is in the second position. Thus, when the catch 300 is located above the support plate 3000, the catch 300 is in the second position, and the catch 300 is supported between the base 100 and the support surface of the support plate 3000. At this time, the second portion 320 of the buckle 300 extends along the second direction, and the supporting force of the supporting plate 3000 on the second portion 320 will be along the second direction, so as to reduce the loss of the supporting force and facilitate the improvement of the supporting effect.

Optionally, the fastener 1000 provided in the embodiment of the present utility model may further include a restoring member 500, where the restoring member 500 may connect the buckle 300 and the base 100, and may provide a restoring force for the buckle 300 to maintain the buckle 300 in the second position.

Specifically, during the process of the buckle 300 passing through the groove of the support plate 3000, the inner groove wall of the groove of the support plate 3000 compresses the reset member 500 to be elastically deformed. After the catch 300 is separated from the supporting plate 3000, the reset member 500 is restored to the deformed state, and the catch 300 is restored to the second position.

Illustratively, the reset member 500 may be a linear spring that may be connected between the buckle 300 and the base 100 to achieve a reset function using a tensile force in an axial direction of the linear spring; as another example, the reset member 500 may be a torsion spring, which may be sleeved on the hinge member 200, and both ends of which may respectively abut against the base 100 and the buckle 300, so as to implement a reset function by using a torsion force of the torsion spring; still another exemplary embodiment of the reset member 500 may be a V-shaped spring plate with a bent angle as shown in fig. 5 and 6, wherein one side of the bent angle of the spring plate may abut against the base 100, and the other side of the bent angle of the spring plate may abut against the buckle 300, so as to implement the reset function by using the angle change of the bent angle.

Referring to fig. 3, 5 and 6, in order to facilitate adjusting the position of the built-in range hood relative to the support plate 3000, the holder 1000 according to the embodiment of the present utility model may further include a hinge member 200, wherein the hinge member 200 may be disposed through the base 100 along a first direction, and the position of the hinge member 200 relative to the base 100 in a second direction, which is opposite to the first direction, may be adjusted. When the holder 1000 assists in assembling the housing 2000 and the support plate 3000 of the range hood, the second direction is the axial direction of the recess of the support plate 3000. In addition, the first end of the above-mentioned clasp 300 may be hinged with the base 100 by the hinge 200. In this manner, by enabling the position of the hinge 200 relative to the base 100 in the second direction to be adjusted, the position of the first end of the buckle 300 relative to the base 100 in the second direction is made adjustable, so that the height of the base 100 relative to the support plate 3000 is made adjustable, and thus the height of a range hood or other device connected to the base 100 relative to the support plate 3000 is made adjustable. In summary, the holder 1000 provided by the embodiment of the present utility model has the advantages of facilitating installation of the apparatus and adjusting the heights of the apparatus and the support plate 3000.

With continued reference to fig. 3, 5 and 6, the base 100 may be provided with a stop 110, and at least a portion of the hinge 200 slides in a second direction relative to the stop 110. The holder 1000 may further include a locking member 400, and the locking member 400 may be provided to the base 100 and lock the position of the hinge 200 in the second direction with respect to the base 100.

Specifically, the hinge 200 slides in the second direction with respect to the stopper 110 of the base 100, and when the hinge 200 slides to the target position, the hinge 200 is locked with the base 100 by the locking member 400 to avoid the hinge 200 from moving with respect to the base 100.

For example, the limiting portion 110 may be an elongated chute as shown in fig. 5 and 6, and the chute may extend along the second direction. At least a portion of the hinge 200 may be slidably disposed in the chute.

Among other possible implementations, the locking member 400 may be as follows:

in one possible implementation, the locking member 400 may be a nut, which may be sleeved on the hinge member 200 and may be screwed with the hinge member 200, and one end of which abuts against the base 100. In this way, the end of the nut is tightly abutted against the base 100 by the screw tightening force between the nut and the hinge 200, so that the pressure between the nut and the base 100 is larger, the friction between the nut and the base 100 is larger, the position of the nut relative to the base 100 in the second direction is locked, and the position of the hinge 200 in threaded connection with the nut relative to the base 100 in the second direction is locked.

In another possible implementation, referring to fig. 3, 5 and 6, the locking member 400 may be a screw, one end of which is rotatably disposed on the base 100, and the other end of which is threaded through the hinge 200 and is screwed with the hinge 200.

Specifically, when the screw is rotated, the hinge 200 screwed with the screw is restricted by the base 100 to slide in the second direction. When the screw stops rotating, the position of the hinge 200 in the second direction with respect to the base 100 is locked by means of the screw tightening force between the screw and the hinge 200.

In addition, the hinge 200 may have several possible implementations:

in one possible implementation, the hinge 200 is a rod with external threads. As such, the external threads of the hinge 200 may be threadably coupled with the nuts or screws mentioned above. The first end of the buckle 300 may be sleeved on the rod body, and rotate with the axis of the rod body as the axis of the rotating shaft 210.

In another possible implementation, the hinge 200 includes a connection base 220 and two rotating shafts 210, and two ends of the connection base 220 along the first direction are connected to the two rotating shafts 210 in a one-to-one correspondence. Thus, the two rotating shafts 210 may be respectively disposed on two sides of the first end of the buckle 300 along the first direction, so that the first end of the buckle 300 can stably rotate through the two rotating shafts 210. In addition, the two rotating shafts 210 are connected through the connecting seat 220, so as to reduce the length of the rotating shaft 210 and avoid the breakage of the rotating shaft 210. In addition, when the locking member 400 is the screw rod mentioned above, the screw rod may be disposed through the connection base 220 and may be screwed with the connection base 220. The arrangement of the threaded holes in the connecting seat 220 has the advantage of convenient processing compared with the arrangement of the threaded holes in the rod body.

As mentioned above, the hinge 200 enables adjustment of the position of the hinge 200 by sliding in the second direction with respect to the stopper 110 of the base 100. In addition to this, the modes shown in fig. 7 and 8 are also possible. Specifically, fig. 7 is a side view of a base 100 of another fastener 1000 according to an embodiment of the present utility model, and fig. 8 is a partial cross-sectional view of another fastener 1000 according to an embodiment of the present utility model.
