Description

Technical Field

[0001] This utility model relates to the technical field of piggy bank accessories, and in particular to a locking mechanism and a piggy bank. Background Technology

[0002] With the continuous development of the economy, family education should also pay more attention to money management education, helping children learn to use their own money reasonably. The most traditional way is to use piggy banks, which can help children save their spare change and cultivate their financial management concept.

[0003] Most existing piggy banks are made of ceramic. Ceramic piggy banks generally lack a coin slit; the coins can only be retrieved by breaking the bank when needed or when the bank is full. These ceramic piggy banks are only for single use and cannot be reused. While some piggy banks have a larger opening at the bottom for easy retrieval, these are less secure, as anyone, including the owner, can easily open them and take the coins. Therefore, this paper provides a locking mechanism and a piggy bank to address these issues. Utility Model Content

The drive assembly 13 is disposed within the main housing 11 and is connected to the latch assembly 12, driving the latch assembly 12 to move, thereby enabling the piggy bank to be opened or closed. The first fixing plate 14 is fixedly disposed above the latch assembly 12 and the drive assembly 13, limiting the latch assembly 12 and fixing the drive assembly 13. The second fixing plate 15 is fixedly disposed above the latch assembly 12, limiting its movement.

[0029] Please see Figures 1-4 As shown, in this embodiment, the main housing 11 is provided with a mounting cavity 111 and a limiting post 112. The drive assembly 13 is disposed in the mounting cavity 111. The latch assembly 12 moves through the limiting post 112, and the limiting post 112 performs a limiting and guiding operation on the latch assembly 12. A lock hole 113 is provided through the side of the main housing 11, and the latch assembly 12 passes through the main housing 11 through the lock hole 113. A plurality of fixing posts 114 are also integrally provided in the main housing 11. The latch assembly 12, the drive assembly 13, the first fixing plate 14 and the second fixing plate 15 are respectively disposed in the main housing 11 through the corresponding fixing posts 114.

[0030] Please see Figure 1 , Figure 2 , Figure 3 and Figure 5As shown, in this embodiment, the latch assembly 12 includes a guide seat 121, a latch 122, and an elastic element 123. The guide seat 121 is fixedly installed in the main housing 11 by a corresponding fixing post 114. The latch 122 is slidably disposed on the guide seat 121 and moves through the main housing 11 via the lock hole 113. The drive assembly 13 is connected to the latch 122 and drives the latch 122 to move on the guide seat 121, thereby realizing the opening or closing operation of the piggy bank. The guide seat 121 supports and guides the latch 122. The elastic element 123 is disposed between the guide seat 121 and the latch 122, and provides a restoring clamping force to the latch 122, so that the latch 122 is in a locked state. Specifically, the elastic element 123 is a spring.

[0031] Please see Figure 3 and Figure 5 As shown, specifically, the guide seat 121 has multiple fixing holes 1211 through it, and the fastening screws are fixedly connected to the corresponding fixing posts 114 through the multiple fixing holes 1211 respectively; the guide seat 121 has two first limiting grooves 1212 symmetrically arranged, and the two ends of the locking tongue 122 are respectively slidably arranged in the corresponding first limiting grooves 1212, and the movement of the locking tongue 122 is limited and guided by the first limiting grooves 1212; the guide seat 121 is also provided with a first connecting post 1213, and one end of the elastic element 123 is connected to the first connecting post 1213.

[0032] Please see Figure 3 and Figure 5As shown, in this embodiment, the latch 122 includes a sliding block 1221 and a latch body 1222. The sliding block 1221 is movably disposed on the guide seat 121 and is connected to the drive assembly 13, and is in contact with the elastic element 123. The latch body 1222 is fixedly disposed on one side of the sliding block 1221 and movably penetrates the main housing 11 through the lock hole 113. Specifically, guide strips 12211 are symmetrically disposed at both ends of the sliding block 1221. The two guide strips 12211 are slidably disposed in the corresponding first limiting grooves 1212. Through the cooperation of the guide strips 12211 and the first limiting grooves 1212, the guide seat 121 performs a limiting and guiding operation on the latch 122. A second guide groove 12212 is disposed through the sliding block 1221. The second guide groove 12212 is movably disposed through the limiting post 112. Through the cooperation of the second guide groove 12212 and the limiting post 112, the locking and guiding operation on the latch 122 is achieved. Operation: A drive connection part 12213 is provided at the position where the sliding block 1221 contacts the drive assembly 13. The drive connection part 12213 is arc-shaped to facilitate contact and transmission connection with the drive assembly 13. A through hole 12214 is also provided through the sliding block 1221. A second connecting post 12215 is provided in the through hole 12214. The second connecting post 12215 is arranged opposite to the first connecting post 1213. The two ends of the elastic member 123 are respectively connected to the first connecting post 1213 and the second connecting post 12215, thereby providing a restoring elastic force to the locking tongue 122.

[0033] Please see Figures 1-3 As shown, in this embodiment, the drive assembly 13 includes a drive motor 131 and a drive block 132. The drive motor 131 is fixedly installed in the main housing 11 and can rotate in both directions. The drive block 132 is connected to the drive motor 131 and can be connected to the drive connection part 12213, thereby driving the lock tongue assembly 12 to perform the unlocking operation.

[0034] This utility model provides a piggy bank that includes a locking mechanism 10 as described above, which enables the piggy bank to be opened or closed.

[0035] It should be noted that the specific working process of the lock mechanism and piggy bank of this utility model is as follows: When an unlocking operation is required, the drive motor 131 rotates forward to drive the drive block 132 to move, so that the drive block 132 contacts and is connected to the latch 122, thereby driving the latch 122 to retract into the main housing 11 under the guidance of the guide seat 121, while compressing the elastic element 123, thereby realizing the unlocking operation; when a locking operation is required, the drive motor 131 rotates in reverse to drive the drive block 132 to move, so that the drive block 132 slowly disengages from the contact and transmission connection with the latch 122, while under the restoring force of the elastic element 123, the latch 122 moves outward under the guidance of the guide seat 121, thereby realizing the locking operation.

[0036] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0037] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
