Description

Technical Field

[0001] The utility model relates to the technical field of daily life, in particular to a self-locking cup cover and a water cup containing the cup cover. Background Art

[0002] Most existing thermoses, straw cups, and other cups feature lids that open with a single push of a button. This method of opening the lid can easily lead to accidental opening due to external forces such as impact or pressure, resulting in leaks, burns, and other problems. Therefore, a separate locking mechanism, such as a snap ring, is typically provided. However, this locking mechanism requires the user to lock it themselves, and if the user forgets to do so, the same problem of accidental opening can occur. Other existing technologies use a button assembly and multiple sets of elastic components to lock and unlock the button at the push position. However, this self-locking assembly is complex, requires numerous parts, and is inconvenient to assemble. Utility Model Content

The following examples are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0036] like Figures 1-9 As shown, the present invention provides a self-locking cup lid, which includes a lid body 200, a flip cover 300, and a locking assembly 400. The lid body 200 is threadedly connected to the mouth of the cup body 100 and is provided with a water outlet 202 extending vertically therethrough. The first side of the flip cover 300 is hingedly connected to the lid body 200. The second side of the flip cover 300 is engaged with or separated from the lid body 200 via the locking assembly 400. When the flip cover 300 and the lid body 200 are engaged, a receiving chamber is formed between the two. By definition, the direction from the first side of the flip cover 300 to the second side of the flip cover 300 is considered horizontal.

[0037] A sealing plug 302 is provided on the inner wall of the flip cover 300 at a position corresponding to the water outlet 202 , and an upper snap ring 301 is provided on the inner wall of the second side. The upper snap ring 301 is provided with a through hole groove 3011 .

[0038] An installation chamber 201 is provided on one side of the cover body 200 and the second side of the flip cover 300 in the same direction, and the locking assembly 400 is slidably disposed in the installation chamber 201 .

[0039] The mounting chamber 201 is a box body with an opening. The opening of the box body is located opposite the hinged joint between the flip cover and the cover body 200. The bottom surface of the box body is a strip-shaped groove 2011 formed by the upper surface of the cover body 200. The inner wall of the side of the box body opposite the opening is provided with a spring positioning groove 2012 for connecting the self-locking spring 4032 described below. The top surface of the box body is provided with a chamber slot 2013, the outer edge of which is a locking rib 2013a.

[0040] The upper snap ring 301 is engaged with the lock assembly 400 after passing through the bin body slot 2013. In addition, for the convenience of installing the lock assembly 400, the top surface of the box body and the two vertical sides connecting the top surface and the strip groove 2011 are all retracted relative to the outer side wall of the cover body 200.

[0041] The lock assembly 400 includes a lower hook seat 401 , a cover opening button 402 and an elastic push rod assembly 403 .

[0042] The lower hook seat 401 slides laterally within the mounting compartment 201. It is a box-like body with a hollowed-out bottom. An opening is provided on the side of the lower hook seat 401 near the spring positioning slot 2012. Its top surface is provided with a first slot 4011 and a second slot 4012, which are arranged parallel to each other. The second slot 4012 is located adjacent to the spring positioning slot 2012 and coaxially with the compartment slot 2013. A latch 4013 is also provided on the inner wall of the second slot 4012. After the upper snap ring 301 passes through the compartment slot 2013, the latch 4013 engages with the through-hole 3011 of the upper snap ring 301. The first slot 4011 is located on the side of the lower hook seat 401's top surface facing away from the spring positioning slot 2012. Its outer edge, the side facing away from the spring positioning slot 2012, is recessed, forming a stepped surface 4011a. The first slot 4011 is used to connect to the lid opening button 402.

[0043] Preferably, in order to facilitate the engagement between the upper snap ring 301 and the tongue 4013, the bottom surface of the upper snap ring 301 in contact with the tongue 4013 is set to be an arc shape, and the surface of the tongue 4013 in contact with the bottom surface of the upper snap ring 301 is set to be a sloped surface.

[0044] In addition, limiting grooves 4014 are symmetrically provided on both sides of the lower hook seat 401 and below the tongue 4013. A pin shaft 4015 runs through the limiting groove 4014, and both ends of the pin shaft 4015 are respectively connected to the inner wall of the installation chamber 201.

[0045] Preferably, the lower hook seat 401 is horizontally perpendicular to the two horizontal sides, located below the second slot 4012 and relative to the upper snap ring 301, and each is convex and concave toward its center axis, each forming a receiving edge 4016, which provides an accommodating space for the upper snap ring 301 after it is engaged with the tongue 4013.

[0046] The elastic push rod assembly 403 includes a push rod 4031 and a self-locking spring 4032 .

[0047] One top end of the push rod 4031 is a wedge block 4031a, which is placed on the strip groove 2011. The other end of the push rod 4031 is connected to one end of the self-locking spring 4032, and the other end of the self-locking spring 4032 is set in the spring positioning groove 2012.

[0048] The cover opening button 402 includes a first side stop 4021 and a second side stop 4022 that are opposite to each other, and a snap-fitting groove 4023 is provided between the first side stop 4021 and the second side stop 4022 . The snap-fitting groove 4023 opens downward and faces the downward hook seat 401 .

[0049] The second side stop 4022 is a rectangular plate, the upper end of which is located above the snap-fitting groove 4023, and the upper end thereof is concave toward the side of the installation bin 201, forming an L-shaped locking side stop 4025. The lower end of the second side stop 4022 is located below the snap-fitting groove 4023, and the bottom end thereof is provided with a wedge-shaped groove 4024 that matches the above-mentioned wedge block 4031a.

[0050] The lower end of the second side stop 4022 slides in the up and down directions and is engaged in the first slot 4011, and is against the wedge block 4031a. The inner wall of the first side stop 4021 is against the outer side of the step surface 4011a. When the self-locking spring 4032 is in a non-elastic state, the engaging groove 4023 is located above the step surface 4011a, and the locking side stop 4025 is against the outer side of the above-mentioned locking stop 2013a.

[0051] Preferably, the length of the first side stop 4021 below the snap-fitting slot 4023 is smaller than the length of the second side stop 4022 below the snap-fitting slot 4023 .

[0052] Preferably, a drinking port 500 is snap-fitted to the water outlet 202 of the cover body 200 . When the flip cover 300 is buckled onto the cover body 200 , the sealing plug 302 blocks the water outlet of the drinking port 500 .

[0053] Preferably, a filter 501 is further provided at the bottom of the drinking spout 500 .

[0054] The present invention also provides a water cup with the self-locking cup cover. The water cup comprises a cup body 100 , and the cover body 200 is threadedly connected to the cup body 100 .

[0055] The operation process of this utility model:

[0056] After the upper snap ring 301 on the flip cover 300 passes through the housing slot 2013 and the second slot 4012 in sequence, the latch tongue 4013 engages with the through hole slot 3011 of the upper snap ring 301 , and the flip cover 300 is now engaged with the cover body 200 .

[0057] When the first side stop 4021 is pressed downward, it simultaneously drives the second side stop 4022 and the engaging groove 4023 to slide down. In the process of the step surface 4011a gradually engaging with the engaging groove 4023, the locking side stop 4025 also gradually moves down to below the locking side stop 2013a. At the same time, the wedge block 4031a is also subjected to the pressure from the second side stop 4022, and the self-locking spring 4032 is slightly deformed. The cover opening button 402 is further pushed inward, and the cover opening button 402 simultaneously drives the lower hook seat 401 and the wedge block 4031a to move laterally away from the upper snap ring 301. The latch tongue 4013 also moves synchronously toward the upper snap ring 301 until it is disengaged from the through hole groove 3011, and the flip cover 300 is separated from the cover body 200.

[0058] As the wedge block 4031a moves laterally away from the upper retaining ring 301, the self-locking spring 4032 is further deformed. When the thrust acting on the cover opening button 402 disappears, the deformation rebound force of the self-locking spring 4032 drives the wedge block 4031a, the cover opening button 402 and the lower hook seat 401 to reset. At this time, the locking side guard 4025 is also reset to the outside of the above-mentioned locking guard 2013a.

[0059] Since the cover opening button 402 of the present invention needs to first slide down and then push inwards, the flip cover 200 can be released from the cover body, thereby effectively avoiding the situation where the cover opening button 402 is accidentally hit by external force and the cover is opened.

[0060] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
