Description

Technical Field

[0001] This invention belongs to the field of clothing processing, specifically, it relates to a door lock module and a washing machine. Background Technology

[0002] In existing garment handling devices, the outer tub is located inside a drawer, and the outer tub is pulled out of the casing along with the drawer. Due to space constraints in this drawer, the space utilization of each component is very high, making the installation position and space utilization of each key component a challenge. The upper surface of the drawer has a drawer lid with a loading opening, and a door cover on the loading opening. The rear end of the door cover is pivotally mounted on the outer tub drawer lid. Locking the door cover is one problem that needs to be solved.

[0003] In the prior art, the pulsator washing unit is set in a drawer. Due to space limitations, drawer-type washing machines are relatively low. The low space determines that the door locking structure needs to be simple and have high locking strength to prevent the door from being accidentally opened due to washing machine vibration, while not taking up too much vertical space inside the washing machine drawer.

[0004] To address the aforementioned technical issues, high-strength push-button locks can be installed at the bottom of the door cover and the drawer cover. One end of a spring-loaded actuating element is positioned inside the push-button lock, while the other end is slidably positioned in the groove of the locking element. When pressed, the locking element rotates to lock the door cover; pressing again automatically unlocks the door cover. However, a retaining element needs to be installed inside the push-button lock to ensure that the other end of the spring-loaded actuating element remains within the groove of the locking element. Furthermore, the limited space prevents the use of screws for fixing the structure, making the proper installation of the retaining element within the push-button lock a pressing technical problem that urgently needs to be solved.

[0005] In view of this, the present invention is proposed. Summary of the Invention

[0006] The technical problem to be solved by this invention is to overcome the shortcomings of the prior art and provide a door cover lock module. By setting a pressing member, the other end of the elastic pressing member is always located in the groove of the locking member, preventing the other end of the elastic pressing member from falling out of the groove and ensuring the normal use of the door cover lock module. The pressing member can receive the force from the upper part of the door cover lock module housing, pressing the elastic pressing member to rotate in the groove, thereby causing the locking member to rotate and the lock hook to rotate out of the lower part of the door cover lock module housing, thereby locking the door cover. This invention has a low vertical height requirement, high locking strength, and is safe and reliable.

[0007] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is to provide a door cover lock module, including...

[0008] The housing has a receiving cavity, the bottom of which has a first opening;

[0009] A locking element, rotatably mounted in the receiving cavity, the locking element including a locking hook and having a sliding groove;

[0010] An elastic pressing member, with one end disposed in the receiving cavity and the other end slidably disposed in the slide groove, is used to receive the downward force from the top of the housing to press against the locking member. The force is converted into a force to drive the locking member to rotate as the locking member slides in the slide groove. The rotation of the locking member causes the locking hook to extend from the first opening to the outside of the housing and locks the locking member in the rotation direction. After receiving the downward force from the top of the housing again, the locking member is unlocked in the rotation direction.

[0011] The pressing member has one end fixed to the top inside the housing, and the other end extends inside the housing to press against the upper part of the elastic pressing member, so that the other end of the elastic pressing member is located in the groove.

[0012] This invention relates to a door cover lock module, which includes a rotatable locking component within a housing. A groove is provided on the outer wall of the locking component. The invention utilizes a pressing component at the top of the housing. When the elastic pressing component receives a downward force from the top of the housing, the pressing component also receives the downward force from the top of the door cover lock module's housing, pressing the elastic pressing component to rotate within the groove. This causes the locking component to rotate, and the locking hook extends out of the first opening after rotation, locking the door cover. This design minimizes the vertical height of the door cover lock, provides high locking strength, and ensures safety and reliability. Furthermore, it ensures that the other end of the elastic pressing component remains within the groove of the locking component, preventing it from falling out and guaranteeing the normal operation of the door cover lock module.

[0013] Furthermore, the other end of the pressing member is provided with a downwardly protruding portion, which presses against the elastic pressing member.

[0014] Furthermore, the housing includes,

[0015] A bottom shell having a receiving cavity therein, and the locking member being rotatably mounted in the receiving cavity;

[0016] A cover that closes the opening at the top of the receiving cavity, forming the receiving cavity with the receiving cavity;

[0017] The cover is provided with a clearance opening to allow the protrusion to pass.

[0018] Furthermore, the elastic pressing member includes,

[0019] The mounting rod is fixed to the bottom shell on the side opposite to the direction of rotation of the locking member under pressure;

[0020] An extension rod extends from the mounting rod toward the upper part of the locking member;

[0021] A sliding rod is disposed at one end of the extension rod and extends into the sliding groove;

[0022] The protrusion presses against the extension rod, so that the sliding rod is located in the groove;

[0023] Preferably, the extension direction of the pressing member is the same as the extension direction of the elastic pressing member.

[0024] Furthermore, the inner wall of the shell cover is provided with a insertion hole, and one end of the pressing member is inserted into the insertion hole.

[0025] Furthermore, the two ends of the shell cover are provided with downwardly extending insertion portions, which are engaged with the outer wall of the receiving cavity;

[0026] The insertion hole includes a first insertion hole, which is located at the connection between the insertion part and the shell cover. The top of the receiving cavity is provided with a through-hole to avoid the pressing member. One end of the pressing member is inserted into the through-hole and the first insertion hole.

[0027] Furthermore, the insertion hole also includes a second insertion hole, and the inner wall of the shell cover is provided with a protruding pressing member mounting part, located between the first insertion hole and the clearance opening, and the second insertion hole is provided at the connection between the pressing member mounting part and the shell cover;

[0028] One end of the pressing member passes through the second insertion hole and is inserted into the first insertion hole.

[0029] Furthermore, a snap-fit ​​portion is provided on the cover between the pressing member mounting portion and the insertion portion, and a matching snap-fit ​​is provided on the pressing member, the snap-fit ​​being engaged with the snap-fit ​​portion.

[0030] Furthermore, the pressing member is an extended pressing sheet, and the pressing sheet includes sequentially extended components.

[0031] The first segment is inserted into the first connector hole.

[0032] The second segment is connected to the first segment and passes through the second insertion hole. The width of the second segment is smaller than the width of the first segment, and the bayonet is provided on the second segment.

[0033] The bent segment is connected to the second segment, and the middle part protrudes from top to bottom to form the protrusion, which presses against the elastic pressing member.

[0034] The present invention also provides a washing machine having any of the door lock modules described above.

[0035] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art.

[0036] (1) The door cover lock module of the present invention has a rotatable locking member inside the housing and a sliding groove on the outer wall of the locking member. The present invention provides a pressing member at the top of the housing. When the elastic pressing member receives the downward force from the top of the housing, the pressing member can receive the downward force from the top of the housing of the door cover lock module and press the elastic pressing member to rotate in the sliding groove, thereby causing the locking member to rotate. After the lock hook rotates, it extends out of the first opening and locks, thereby locking the door cover. The vertical height of the door cover lock is low, the locking strength is high, and it is safe and reliable. It can also keep the other end of the elastic pressing member always in the sliding groove of the locking member, preventing the other end of the elastic pressing member from falling out of the sliding groove, thus ensuring the normal use of the door cover lock module.

[0037] (2) By inserting one end of the pressing member into the inner wall of the shell cover, this invention saves the space occupied by the pressing member in the receiving cavity, eliminates the need for additional installation structures, and features low structural cost and simple installation.

[0038] The specific embodiments of the present invention will now be described in further detail with reference to the accompanying drawings. Attached Figure Description

[0056] like Figures 1 to 11 As shown, the present invention provides a door cover lock module.

[0057] In one embodiment, the door cover lock module includes a housing 1, a locking member 3, and an elastic pressing member 2.

[0058] The housing 1 has a receiving cavity, and the bottom of the receiving cavity has a first opening 114. The locking member 3 is rotatably mounted in the receiving cavity. The locking member 3 includes a locking hook 33, and the outer wall of the locking member 3 has a sliding groove 31.

[0059] One end of the elastic pressing member 2 is disposed on the receiving cavity, and the other end is slidably disposed in the slide groove 31. It is used to receive the downward force from the top of the housing 1 to press against the locking member 3. The sliding in the slide groove 31 is converted into a force to drive the locking member 3 to rotate. After the locking member 3 rotates, the locking hook 33 extends from the first opening 114 to the outside of the housing 1 and locks the locking member 3 in the rotation direction. After receiving the downward force from the top of the housing 1 again, the locking member 3 is unlocked in the rotation direction.

[0060] The door cover lock module of the present invention has a rotatable locking member 3 inside the housing 1. A sliding groove 31 is provided on the outer wall of the locking member 3. When the elastic pressing member 2 receives the downward force from the top of the housing 1, the other end of the elastic pressing member 2 presses the locking member 3 downward and moves along the sliding groove 31 on the locking member 3, thereby causing the locking member 3 to rotate. The locking hook 33 extends out of the first opening 114 and locks. This allows the locking hook 33 of the door cover lock module to cooperate with the locking groove on the washing machine drawer to lock the door cover onto the washing machine drawer. It occupies a small vertical height of the door cover lock, has high locking strength, can achieve press locking, and the locking operation is simple, improving the user experience.

[0061] The locking hook 33 on the locking member 3 of the present invention can be rotatably extended out of the first opening 114 or retracted into the receiving cavity.

[0062] The elastic pressing member 2 is disposed in the receiving cavity. One end of the elastic pressing member 2 is fixed to the receiving cavity, and the other end of the elastic pressing member 2 is located between the locking member 3 and the top of the housing 1, that is, the other end of the elastic pressing member 2 is located between the locking member 3 and the top wall of the receiving cavity.

[0063] The other end of the elastic pressing member 2 is used to receive a downward force from the top wall of the receiving cavity, pressing the locking member 3 downward to rotate, so that the sliding groove 31 of the locking member 3 slides along the other end of the elastic pressing member 2 until the locking hook 33 extends out of the first opening 114.

[0064] Furthermore, the slide groove 31 has a closed track and is disposed on the outer wall of the locking member 3. The slide groove 31 has a locking groove section 312 for locking the rotation of the locking member 3.

[0065] When the other end of the elastic pressing member 2 is subjected to a downward force at the top of the housing 1, the locking member 3 rotates until the other end of the elastic pressing member 2 is located in the locking groove section 312 and the locking hook 33 extends out of the first opening 114. At this time, the downward force at the top of the housing 1 disappears, and the other end of the elastic pressing member 2 is locked in the locking groove section 312, and the door cover lock module is locked.

[0066] Furthermore, the slide groove 31 also includes a sliding groove segment 311 and a recovery groove segment 313, wherein the sliding groove segment 311, the locking groove segment 312 and the recovery groove segment 313 are connected end to end in sequence to form a closed trajectory.

[0067] Under the downward pressure of the top of the housing 1, the other end of the elastic pressing member 2 moves from the initial position at the connection of the sliding groove section 311 and the recovery groove section 313 along the sliding groove section 311 to the locking groove section 312, thereby locking the other end of the elastic pressing member 2 into the locking member 3. After the downward pressure of the top of the housing 1 is applied again, the other end of the elastic pressing member 2 slides out of the locking groove section 312 and moves along the recovery groove section 313 back to the initial position, allowing the locking member 3 to rotate freely.

[0068] Furthermore, each connection point of the sliding groove section 311, the locking groove section 312, and the recovery groove section 313 is provided with a one-way limiting part, which is used to restrict the other end of the elastic pressing member 2 from moving in the same direction in a closed trajectory.

[0069] Specifically, when the other end of the elastic pressing member 2 is in the initial position of the sliding groove 31, after receiving the downward force from the top of the housing 1, it can only slide towards the sliding groove section 311 under the guidance of the unidirectional limiting part. The other end of the elastic pressing member 2 can only slide sequentially along the sliding groove section 311, the locking groove section 312, and the restoring groove section 313.

[0070] Furthermore, one end of the recovery groove 313 is positioned at the initial position of the locking member 3, and the other end of the recovery groove 313 extends outward in the circumferential direction toward the locking hook 33.

[0071] One end of the sliding groove segment 311 is set at the initial position of the locking member 3, and the other end of the sliding groove segment 311 is offset from the recovery groove segment 313 in the axial direction of the rotation of the locking member 3, and extends outward in the direction of the locking hook 33.

[0072] The sliding groove section 311 extends in the same direction as the recovery groove section 313.

[0073] The locking groove 312 extends from the other end of the sliding groove 311 in the opposite direction to the direction of the force pressing and rotating of the locking member 3, and then extends in the opposite direction to connect with the other end of the recovery groove 313.

[0074] When the other end of the elastic pressing member 2 is in the initial position of the sliding groove 31, after receiving the downward force applied by the user from the top of the housing 1, it slides in the sliding groove section 311 under the guidance of the one-way limiting part, and the other end of the elastic pressing member 2 moves downward in the housing 1; when it moves to the other end of the sliding groove section 311, the other end of the elastic pressing member 2 stops moving downward in the housing 1, and at this time the user will stop applying the downward force.

[0075] After the force disappears, the other end of the elastic pressing member 2 moves upward into the locking groove section 312 under the action of the one-way limiting part, so that the locking member 3 is locked and rotated.

[0076] When the user applies a downward force from the top of the housing 1 again, the other end of the elastic pressing member 2 moves downward inside the housing 1 and stops moving downward when it reaches the connection between the locking groove 312 and the recovery groove 313. At this time, the user will stop applying the downward force.

[0077] After the force disappears, the other end of the elastic pressing member 2 moves upward into the recovery groove section 313 under the action of the one-way limiting part, and the locking member 3 can rotate freely.

[0078] Preferably, the other end of the recovery groove 313 is flush with the other end of the sliding groove 311 in the rotational axial direction of the locking member 3. The middle portion of the locking groove 312 is recessed in the opposite direction to the extension direction of the recovery groove 313 and the sliding groove 311.

[0079] Furthermore, one end of the elastic pressing member 2 is fixed to the bottom of the receiving cavity, and the other end is bent and extended to the space between the top wall of the housing 1 and the locking member 3. The other end of the elastic pressing member 2 is provided with a downwardly extending sliding rod 21, which is slidably disposed in the sliding groove 31.

[0080] Furthermore, the housing 1 includes a bottom shell 11 and a cover 12.

[0081] The bottom shell 11 has a receiving cavity 1111, and the locking member 3 is rotatably installed in the receiving cavity 1111. The shell cover 12 closes the opening at the top of the receiving cavity 1111, forming the receiving cavity with the receiving cavity 1111.

[0082] The bottom shell 11 has a fixing part 113 located on the side opposite to the direction of rotation of the locking member 3 under pressure. One end of the elastic pressing member 2 is fixed to the fixing part 113.

[0083] The first opening 114 is disposed on the bottom wall of the bottom shell 11. The fixing part 113 and the first opening 114 are respectively located on the bottom walls of the receiving cavities on both sides of the rotation direction of the locking member 3.

[0084] The fixing part 113 protrudes from the bottom wall inside the bottom shell 11.

[0085] The elastic pressing member 2 includes a mounting rod 22, an extension rod 23, and a sliding rod 21 connected in sequence.

[0086] The mounting rod 22 is vertically disposed in the fixing part 113. The extension rod 23 extends from the top of the mounting rod 22 toward the upper part of the locking member 3. The sliding rod 21 extends downward from the extension rod 23 into the sliding groove 31.

[0087] The extension rod 23 of the elastic pressing member 2 extends between the top wall of the housing 1 and the locking member 3.

[0088] Furthermore, the locking element 3 includes a cam 32 and a locking hook 33.

[0089] The cam 32 is rotatably mounted inside the housing 1 via a rotating shaft. The bottom shell 11 has mounting holes on opposite sides, and the rotating shaft passes through the two mounting holes and the shaft hole of the cam 32, thereby rotatably fixing the cam 32 to the bottom shell 11.

[0090] The locking hook 33 extends along the rotation direction of the cam 32 and is disposed on the outer peripheral wall of the cam 32, and continues to extend outward until it protrudes from the cam 32. The sliding groove 31 is disposed on the outer wall of the locking hook 33.

[0091] Preferably, the bottom shell 11 is a bottom shell 11 with a certain extension length, such as a long strip or a boat-shaped bottom shell. The pivot is arranged in the width direction of the bottom shell 11.

[0092] Furthermore, the door lock module also includes an elastic element 4.

[0093] One end of the elastic element 4 is fixed to the receiving cavity, and the other end is connected to the locking element 3, which is used to provide a restoring force for the locking element 3 to return to its initial position after unlocking.

[0094] Specifically, when the applied force disappears again, the other end of the elastic pressing member 2 moves into the recovery groove section 313 under the action of the one-way limiting part, and the locking member 3 can rotate freely. The elastic member 4 can provide the force for the locking member 3 to rotate until the other end of the elastic pressing member 2 moves to the initial position.

[0095] By incorporating an elastic element 4, the present invention can stretch the locking element 3 when it is compressed and rotated in the initial position, and provide restoring force when it moves from the recovery groove 313 back to the initial position. This allows the user to lock the door cover after pressing it and automatically unlock it after pressing it again, thus improving the user experience.

[0096] Preferably, the door cover lock module of this embodiment has the specific structure of the door cover lock of any of the following embodiments.

[0097] In one embodiment, the door cover lock module includes a housing 1, a locking element 3, an elastic pressing element 2, and an elastic element 4.

[0098] The housing 1 has a receiving cavity, and the bottom of the receiving cavity has a first opening 114. The locking member 3 is rotatably mounted in the receiving cavity. The locking member 3 includes a locking hook 33. The locking member 3 has a sliding groove 31.

[0099] One end of the elastic pressing member 2 is disposed in the receiving cavity, and the other end is slidably disposed in the slide groove 31. It is used to receive the downward force from the top of the housing 1 to press against the locking member 3. The sliding in the slide groove 31 is converted into a force to drive the locking member 3 to rotate. After the locking member 3 rotates, the locking hook 33 extends from the first opening 114 to the outside of the housing 1 and locks the locking member 3 in the rotation direction. After receiving the downward force from the top of the housing 1 again, the locking member 3 is unlocked in the rotation direction.

[0100] One end of the elastic element 4 is fixed to the receiving cavity, and the other end is connected to the locking element 3, which is used to provide the restoring force for the locking element 3 to reset after unlocking.

[0101] This invention relates to a door cover lock module, which includes a rotatable locking member 3 within a housing 1. A groove 31 is provided on the outer wall of the locking member 3. When the elastic pressing member 2 receives a downward force from the top of the housing 1, the other end of the elastic pressing member 2 presses down on the locking member 3 and moves along the groove 31, causing the locking member 3 to rotate. After the locking hook 33 rotates, it extends out of the first opening 114 and locks. Upon receiving another downward force, it automatically unlocks under the restoring force of the elastic member 4. This design is convenient to use, allowing the locking hook 33 of the door cover lock module to engage with the locking groove on the washing machine drawer to lock the door cover onto the drawer. It occupies a small vertical height of the door cover lock, has high locking strength, and enables press-to-lock operation. The locking operation is simple and improves the user experience.

[0102] The elastic pressing member 2 is disposed inside the receiving cavity.

[0103] Furthermore, a notch 1121a is provided on the peripheral wall of the receiving cavity, and one end of the elastic member 4 passes through the notch 1121a and is engaged with the peripheral wall of the receiving cavity.

[0104] The locking member 3 has an abutment portion 34 that extends outward along the rotation axis. The other end of the elastic member 4 is slidably abutted against the outer peripheral wall of the abutment portion 34 on the side away from the notch 1121a, for stretching after the locking member 3 is compressed and rotated.

[0105] The notch 1121a is provided on one side of the rotation direction of the locking member 3. The notch 1121a and the first opening 114 are respectively located on opposite sides of the rotation direction of the locking member 3.

[0106] The other end of the elastic member 4 extends beyond the abutting portion 34 and slides against the end of the abutting portion 34 away from the notch 1121a, that is, slides against the end of the abutting portion 34 near the first opening 114.

[0107] Preferably, the abutting portion 34 has a groove on the side opposite to the notch 1121a, and the other end of the elastic member 4 can slide against the groove.

[0108] The present invention has one end of the elastic member 4 passing through the notch 1121a of the peripheral wall of the receiving cavity and snapping it onto the peripheral wall of the receiving cavity, and the other end extending over the abutment part 34 and slidingly abutting against the other side of the abutment part 34. It does not require a screw fixing structure, is simple to install, occupies little space, reduces the vertical space occupied, and ensures that the door lock module can be applied to the door cover of a drawer-type washing machine.

[0109] Furthermore, the housing 1 includes a bottom shell 11 and a cover 12.

[0110] The bottom shell 11 has a receiving cavity 1111, and the locking member 3 is rotatably installed in the receiving cavity 1111. The cover 12 closes the opening at the top of the receiving cavity 1111, forming the receiving cavity with the receiving cavity 1111.

[0142] Preferably, the door cover lock module of this embodiment has the specific structure of the door cover lock of any of the above and below embodiments.

[0143] In one embodiment, the door cover lock module includes a housing 1, a locking member 3, an elastic pressing member 2, and a pressing member 5.

[0144] The housing 1 has a receiving cavity, the bottom of which has a first opening 114. The locking member 3 is rotatably mounted in the receiving cavity. The locking member 3 includes a locking hook 33 and has a sliding groove 31.

[0145] One end of the elastic pressing member 2 is disposed in the receiving cavity, and the other end is slidably disposed in the slide groove 31. It is used to receive the downward force from the top of the housing 1 to press against the locking member 3. The sliding in the slide groove 31 is converted into a force to drive the locking member 3 to rotate. After the locking member 3 rotates, the locking hook 33 extends from the first opening 114 to the outside of the housing 1 and locks the locking member 3 in the rotation direction. After receiving the downward force from the top of the housing 1 again, the locking member 3 is unlocked in the rotation direction.

[0146] One end of the pressing member 5 is fixed to the top inside the housing 1, and the other end extends inside the housing 1 to press against the upper part of the elastic pressing member 2, so that the other end of the elastic pressing member 2 is located in the groove 31.

[0147] This invention relates to a door cover lock module, which includes a rotatable locking member 3 within a housing 1. A sliding groove 31 is provided on the outer wall of the locking member 3. The invention utilizes a pressing member 5 at the top of the housing 1. When the elastic pressing member 2 receives a downward force from the top of the housing 1, the pressing member 5 receives the downward force from the top of the housing 1 of the door cover lock module, pressing the elastic pressing member 2 to rotate within the sliding groove 31. This causes the locking member 3, with its locking hook 33, to rotate and extend beyond the first opening 114, thus locking the door cover. This design results in a low vertical height requirement, high locking strength, and reliable safety. Furthermore, it ensures that the other end of the elastic pressing member 2 remains within the sliding groove 31 of the locking member 3, preventing it from falling out and guaranteeing the normal operation of the door cover lock module.

[0148] The other end of the pressing member 5 is provided with a downward protrusion, which presses against the elastic pressing member 2.

[0149] The present invention provides a protrusion on the pressing member 5, which presses the elastic pressing member 2 against the elastic pressing member 2 in real time, so that the elastic pressing member 2 is located in the sliding groove 31, thus saving as much space as possible in the cavity occupied by the pressing member 5.

[0150] Furthermore, the housing 1 includes a bottom shell 11 and a cover 12.

[0151] The bottom shell 11 has a receiving cavity 1111, and the locking member 3 is rotatably installed in the receiving cavity 1111. The shell cover 12 closes the opening at the top of the receiving cavity 1111, forming the receiving cavity with the receiving cavity 1111. The shell cover 12 is provided with a clearance opening 126 for avoiding the protrusion.

[0152] When the downward force on the top of the housing 1 is too great, the protrusion of the pressing member 5 can move into the relief opening 126 on the top of the housing 1 to avoid excessive pressure causing damage to the pressing member 5 or the locking member 3.

[0153] Furthermore, the elastic pressing member 2 includes a mounting rod 22, an extension rod 23, and a sliding rod 21.

[0154] The mounting rod 22 is fixed to the bottom shell 11 on the side opposite to the direction of rotation of the locking member 3 under pressure. The extension rod 23 extends from the mounting rod 22 toward the upper part of the locking member 3. The sliding rod 21 is disposed at one end of the extension rod 23 and extends into the sliding groove 31.

[0155] The protrusion presses against the extension rod 23, so that one end of the sliding rod 21 is always located in the groove 31.

[0156] Preferably, the extending direction of the pressing member 5 is the same as the extending direction of the elastic pressing member 2.

[0157] Furthermore, the inner wall of the shell cover 12 is provided with a plug hole, and one end of the pressing member 5 is inserted into the plug hole.

[0158] By inserting one end of the pressing member 5 into the inner wall of the shell cover 12, the present invention can save the space occupied by the installation of the pressing member 5 in the receiving cavity, without the need for additional installation structure, resulting in low structural cost and simple installation.

[0159] Furthermore, the two ends of the shell cover 12 are provided with downwardly extending insertion portions 122, which are engaged with the outer wall of the receiving cavity 1111.

[0161] The insertion hole also includes a second insertion hole 1241. A protruding pressing member mounting portion 124 is provided on the inner wall of the cover 12, located between the first insertion hole 123 and the clearance opening 126. The second insertion hole 1241 is located at the connection between the pressing member mounting portion 124 and the cover 12. One end of the pressing member 5 passes through the second insertion hole 1241 and is inserted into the first insertion hole 123.

[0162] Preferably, the first insertion hole 123 and the second insertion hole 1241 are arranged to extend through the pressing member 5.

[0163] The cover 12 has a through opening opposite to the mounting portion 124 of the pressing member, which facilitates the installation of the pressing member 5 and allows for easy observation of the installation status of the pressing member 5.

[0164] The present invention provides a first insertion hole 123 and a second insertion hole 1241 on the shell cover 12. One end of the pressing member 5 passes through the second insertion hole 1241 and is inserted into the first insertion hole 123. This ensures that one end of the pressing member 5 has sufficient fixing strength, and the structure is simple and easy to install.

[0165] Furthermore, a snap-fit ​​portion 125 is provided on the cover 12 between the pressing member mounting portion 124 and the insertion portion 122, and a matching snap-fit ​​slot 51 is provided on the pressing member 5, which snaps into the snap-fit ​​portion 125.
