Description

Technical Field

[0001] This application relates to the field of cake mold technology, and in particular to a locking device and a cake mold. Background Technology

[0002] Cake molds are used to shape cakes during the baking process. A cake mold consists of a ring made of long, rolled steel strips. The diameter of the ring is changed by altering the degree of overlap between the ends of the steel strip, allowing for the creation of cakes of different sizes. Current cake molds use pressure plates on the steel strips to press the overlapping portions together, preventing slippage. However, this pressure plate design is prone to displacement or loosening during baking, which can affect the cake's shape. Utility Model Content

[0020] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0021] Please see Figure 1-5The locking device 100 includes a first connecting member 1, a second connecting member 2, a first locking member 3, and a second locking member 4. The first connecting member 1 includes a first end 11 and a second end 12 disposed opposite to each other, with the first end 11 used to clamp the top end of the ring body 200. The second connecting member 2 includes a third end 21 and a fourth end 22 disposed opposite to each other, with the third end 21 used to clamp the bottom end of the ring body 200. The first locking member 3 includes a fifth end 31 and a sixth end 32 disposed opposite to each other, with the fifth end 31 rotatably connected to the fourth end 22 and connected to the second end 12. The fifth end 31 can rotate relative to the fourth end 22 about a rotation axis z, thereby causing the connection between the second end 12 and the fifth end 31 to rotate about the rotation axis z. The sixth end 32 is provided with a first locking portion 321. The second locking member 4 is fixed to the second connecting member 2 and is provided with a second locking portion 41. When the fifth end 31 rotates to the first position relative to the fourth end 22, the first locking part 321 locks with the second locking part 41, and the fifth end 31 applies a pulling force to the second end 12 and the fourth end 22 respectively to drive the first end 11 closer to the third end 21.

[0022] When the locking device 100 is used in the cake mold 1000, the first end 11 is fastened to the top of the overlapping portion 203 of the ring body 200, and the third end 21 is fastened to the bottom of the overlapping portion 203 of the ring body 200. When the fifth end 31 rotates relative to the fourth end 22 to the first position, the fifth end 31 applies a pulling force to the second end 12 and the fourth end 22 respectively to drive the first end 11 closer to the third end 21, thereby fastening the overlapping portion 203 of the ring body 200 through the first end 11 and the third end 21 to maintain the diameter of the ring body 200. The first locking part 321 and the second locking part 41 are locked, and the sixth end 32 is fixed to the second locking member 4.

[0023] The locking device 100 provided in this application embodiment drives the first end 11 to approach the third end 21 by rotating the fifth end 31 relative to the fourth end 22, so that the first end 11 and the third end 21 fasten the overlapping portion 203 of the ring body 200. Furthermore, the first locking part 321 locks with the second locking part 41 when the fifth end 31 rotates to the first position, so as to lock the fifth end 31 in the first position. Compared with the traditional cake mold that only uses a pressing sheet to press the ring body, the locking device 100 provided in this application embodiment has higher reliability and helps to reduce the problem of the ring body 200 loosening during the baking process.

[0024] In some embodiments, the first locking part 321 includes a slot, and the second locking part 41 includes a hook. When the fifth end 31 rotates relative to the fourth end 22 to the first position, the hook engages with the slot.

[0026] In some embodiments, the second locking member 4 is provided with an elastic member 5. The second locking part 41 includes a connecting arm 412, which includes a seventh end 4121 and an eighth end 4122 disposed opposite to each other. The seventh end 4121 is rotatably connected to the second locking member 4, and a hook is disposed at the eighth end 4122, which is connected to the elastic member 5. The eighth end 4122 can reciprocate between a locked position and an unlocked position under the drive of the seventh end 4121. When the eighth end 4122 is in the locked position, the hook engages with the slot. When the eighth end 4122 is in the unlocked position, the hook disengages from the slot. The elastic member 5 is used to generate an elastic force to resist the movement of the eighth end 4122 from the locked position to the unlocked position.

[0027] Please see Figure 5 and Figure 6 In some embodiments, the seventh end 4121 is provided with a mounting hole 4121a, and the second locking member 4 is provided with a mounting protrusion 43.

[0029] Please see Figure 7 and Figure 8 In other embodiments, the second locking member 4 is provided with an elastic member 5. The second locking part 41 includes a connecting arm 412, which includes a seventh end 4121 and an eighth end 4122 disposed opposite to each other. The seventh end 4121 is fixed to the second locking member 4, and the eighth end 4122 is connected to the elastic member 5. The eighth end 4122 can be elastically bent relative to the seventh end 4121 to reciprocate between a locked position and an unlocked position. When the eighth end 4122 is in the locked position, the hook engages with the slot. When the eighth end 4122 is in the unlocked position, the hook disengages from the slot. The elastic member 5 is used to generate an elastic force to resist the movement of the eighth end 4122 from the locked position to the unlocked position.

[0030] It is understandable that the seventh end 4121 can be fixed to the second locking member 4 by means of welding, fastening with fasteners or bonding.

[0034] In some embodiments, the elastic member 5 is used to generate an elastic force against the movement of the eighth end 4122 from the locked position to the unlocked position when pressed. By pressing the two opposing eighth ends 4122, the two eighth ends 4122 are moved towards each other, thereby causing the first hook 4111 and the second hook 4112 to avoid the first slot portion 3211 and the second slot portion 3212, respectively.

[0035] In some other embodiments, the number of connecting arms 412 is one, the hook only includes the first hook 4111, the slot only includes the first slot 3211, or the hook only includes the second hook 4112, and the slot only includes the second slot 3212.

The overlapping portion 2011 of the eleventh end 201 and the overlapping portion 2021 of the twelfth end 202 and the eleventh end 201 constitutes the overlapping portion 203 of the ring body 200. The eleventh end 201 and the twelfth end 202 can slide relative to each other about the axis of the ring body 200, thereby increasing or decreasing the overlapping area of ​​the eleventh end 201 and the twelfth end 202, and thus increasing or decreasing the diameter of the ring body 200.

[0062] In some embodiments, the ring 200 is formed by winding a stainless steel sheet.

[0063] In some embodiments, the cake mold 1000 includes a limiting ring 300, which is sleeved on the overlapping portion 203 of the ring body 200. The limiting ring 300 is used to limit the overlapping portion 203 of the ring body 200 in the axial direction of the ring body 200.

[0064] In some embodiments, the fourth end 22 is fixed to the outer peripheral wall of the ring body 200. Fixing the fourth end 22 to the outer peripheral portion of the ring body 200 helps to reduce the problem of the second locking member 4 causing the fourth end 22 to wobble relative to the ring body 200 when the first locking part 321 is not locked to the second locking part 41.

[0065] In some embodiments, the fourth end 22 is welded and fixed to the outer peripheral wall of the ring body 200. It is understood that in other embodiments, the fourth end 22 may also be fixed to the ring body 200 by means of bonding, riveting, etc.

[0066] The above are merely embodiments of this application and do not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
