Description

Technical Field

[0001] This utility model relates to the field of lock technology, and in particular to a push-button lock for use on the cargo bed cover of a pickup truck. Background Technology

[0002] Pickup trucks, also known as pickup trucks, are a special type of vehicle designed with an open cargo bed specifically for carrying goods. Due to this open design, items inside the cargo bed may get wet in rainy or snowy weather. To solve this problem, a special cover has been designed for the pickup truck cargo bed. This cover can be installed on the cargo bed to cover and protect the goods, preventing them from getting wet from rain or snow.

[0003] While the cargo cover of a pickup truck can protect the contents of the bed from rain or snow, the open design of the bed makes goods vulnerable to theft. Therefore, people have begun to consider installing locks to improve cargo security, such as the lock for a pickup truck bed cover disclosed in existing patent (publication number CN221220102U). However, when using the above-mentioned lock, the first locking element can only be unlocked by pressing the pressing part of the lock from the outside (outside the bed), and cannot be unlocked from the inside (inside the bed). If someone is sitting inside the bed, the inability to unlock the first locking element from the inside makes the lock extremely inconvenient to use.

[0004] In summary, existing push-button locks can usually only be unlocked by pressing from the outside, not from the inside, making them inconvenient to use. Utility Model Content

[0005] In view of the shortcomings of the existing technology, one of the objectives of this utility model is to provide a push-button lock, which aims to solve the technical problem that the existing push-button locks can usually only be unlocked by pressing from the outside and cannot be unlocked by pressing from the inside, resulting in the inconvenience of using push-button locks.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A push-button lock includes a lock shell, a lock body, a torsion spring, and a bolt. The lock shell has a lock cavity with a locking groove inside. The lock body includes a hinge portion hinged to the lock shell, a locking portion and an operating portion located at both ends of the hinge portion. The operating portion has a mounting groove penetrating its opposite surface and communicating with the lock cavity. The bolt is hinged to the operating portion, and a first end of the bolt has a push-button portion located in the mounting groove, and a second end of the bolt has a locking portion capable of locking with the locking groove. The torsion spring includes a coil portion located on the hinge portion, a first shaft portion connected to the bolt, and a locking portion that engages with the locking groove. A second shaft portion is connected to the lock housing; the pressing portion is used to disengage the locking portion from the locking groove; a driving portion is also provided at the second end of the latch; a pressing component is slidably provided on the side of the lock housing opposite to the operating portion, the pressing component is used to push the driving portion to drive the locking portion out of the locking groove; wherein, when the locking portion and the locking groove are in the locked state, the torsion spring is in the energy storage state; when the pressing portion or the pressing component is pressed to unlock the locking portion, the lock body rotates around the lock housing under the kinetic energy provided by the torsion spring, so that the operating portion opens the lock cavity and the locking portion unlocks.

[0008] The beneficial effects of this utility model are as follows:

[0009] When this push-button lock is installed on the cargo bed cover of a pickup truck, the pressing part is located outside the pickup truck cargo bed, and the pressing component is located inside the pickup truck cargo bed. In the locked state, the locking part of the latch engages with the locking groove, the torsion spring is in a stored energy state, the operating part covers the lock cavity, and the locking part is in a locked state. When it is necessary to unlock the lock from the outside, pressing the pressing part of the lock causes the latch to rotate, disengaging the locking part of the latch from the locking groove. Simultaneously, the lock body rotates around the lock shell under the kinetic energy provided by the torsion spring, causing the operating part to open the lock cavity and the locking part to unlock, thus completing the action of unlocking the lock from the outside. When it is necessary to unlock the lock from the inside, pressing the pressing component of the lock pushes the driving part of the latch, causing the locking part of the latch to disengage from the locking groove. Simultaneously, the lock body rotates around the lock shell under the kinetic energy provided by the torsion spring, causing the operating part to open the lock cavity and the locking part to unlock, thus completing the action of unlocking the lock from the inside. Therefore, it can be seen that the push-button lock of this utility model can be unlocked by pressing from the outside or from the inside, overcoming the defect of existing push-button locks that can usually only be unlocked by pressing from the outside and cannot be unlocked by pressing from the inside.

[0010] Furthermore, the pressing component includes a pressing rod and a pressing head. The first end of the pressing rod extends into the lock cavity, and the second end of the pressing rod is located outside the lock cavity. The pressing rod is slidable relative to the lock housing. The pressing head is disposed at the second end of the pressing rod and is used to press the pressing rod to slide relative to the lock housing, thereby driving the locking part to disengage from the locking groove.

[0011] Beneficial effect: Makes it easy to unlock the lock by pressing from the inside.

[0012] Furthermore, the first end of the pressing rod is provided with a limiting part located in the locking cavity. The limiting part is coaxially arranged with the pressing rod and is used to prevent the pressing rod from disengaging from the locking cavity.

[0013] Beneficial effect: It can prevent the pressing rod from dislodging from the locking cavity.

[0014] Furthermore, the push-button lock of this utility model also includes a push-button reset assembly, which includes a mounting plate, a spring, and a sleeve. The mounting plate is disposed on the lock housing, and the sleeve is disposed on the mounting plate along the thickness direction of the mounting plate. The push-button slides sequentially through the sleeve and the mounting plate along the axial direction of the sleeve. A positioning part located inside the sleeve is sleeved on the push-button. The spring is sleeved on the push-button and located inside the sleeve, with both ends of the spring abutting against the mounting plate and the positioning part, respectively.

[0015] Beneficial effect: After the pressing rod pushes the drive part of the locking tongue, the pressing rod can be automatically reset.

[0016] Furthermore, the first end of the pressing rod is configured as a tapered structure, and the driving part is provided with an inclined surface facing the pressing rod. The tapered surface of the tapered structure is used to slide and adapt to the inclined surface.

[0017] Beneficial effect: It allows the locking part of the latch to quickly disengage from the locking groove.

[0018] Furthermore, the push-button lock of this utility model also includes a lock cylinder, which is rotatably mounted on the operating part to prevent the locking part of the lock tongue from disengaging from the locking groove.

[0019] Beneficial effects: Externally, the locking part of the bolt can be prevented from disengaging from the locking groove by rotating the lock cylinder with a key, or the locking part of the bolt can be unlocked from disengaging from the locking groove.

[0020] Furthermore, the push-button lock of this utility model also includes a locking knob, which is rotatably mounted on the lock housing. The locking knob is located on the side of the lock housing facing away from the operating part, and the locking knob is used to prevent the locking part of the bolt from disengaging from the locking groove.

[0021] Beneficial effect: Internally, the locking part of the bolt can be prevented from disengaging from the locking groove by rotating the locking knob, or the locking part of the bolt can be unlocked from disengaging from the locking groove.

[0022] Furthermore, when the locking knob prevents the locking part of the bolt from disengaging from the locking groove, the lock cylinder cannot unlock the bolt from disengaging from the locking groove.

[0023] Beneficial effect: When the locking part of the bolt is locked from the inside by the locking knob, it is impossible to unlock the bolt from the outside by pressing the pressing part of the lock and rotating the lock cylinder with the key.

[0024] Furthermore, the first end of the locking knob is located inside the lock cavity, and the second end of the locking knob is located outside the lock cavity. When the second end of the locking knob is rotated so that the first end of the locking knob abuts against the driving part, the locking knob is in a locked state; when the second end of the locking knob is rotated so that the first end of the locking knob is misaligned with the driving part, the locking knob is in an unlocked state.

[0025] Beneficial effect: It facilitates the locking part of the locking tongue to disengage from the locking groove when locking or unlocking.

[0026] Furthermore, finger gripping portions are provided on opposite sides of the second end of the locking knob.

[0027] Beneficial effect: Facilitates unlocking of the locking knob.

[0028] In summary, the significant advantages of this push-button lock are:

[0029] This utility model's push-button lock can be unlocked by pressing from the outside or from the inside. Externally, the locking part of the bolt can be locked or unlocked by rotating the lock cylinder with the key, disengaging it from the locking groove. Internally, the locking part of the bolt can be locked or unlocked by a locking knob, disengaging it from the locking groove. When the locking part of the bolt is locked from the inside by the locking knob, pressing the pressing part of the lock externally or rotating the lock cylinder with the key will not unlock the bolt from the locking groove, thus greatly improving the lock's security performance.

[0050] Please refer to Figure 1 - Figure 15 This utility model provides a push-button lock, including a lock shell 1, a lock body 2, a lock tongue 3, a torsion spring 4, a push-button component 5, a lock cylinder 6, and a locking knob 7.

[0051] Reference Figure 1 , Figure 2and Figure 6 - Figure 8 The lock housing 1 is provided with a lock cavity 10, the opening of the lock cavity 10 faces outward, and a locking groove 11 is provided inside the lock cavity 10; the lock housing 1 is provided with a mounting base 12 located outside the locking groove 11, and the mounting base 12 is used to install and fix the lock in the position to be installed.

[0052] Reference Figure 1 , Figure 2 , Figure 4 , Figure 12 and Figure 13 The lock body 2 includes a hinge portion 20 that is hinged to the lock housing 1, and a locking portion 21 and an operating portion 22 disposed at both ends of the hinge portion 20. The two sides of the hinge portion 20 are hinged to the lock housing 1 via hinge shafts 203. A groove 201 is formed on the inner sidewall of the hinge portion 20, and a torsion spring winding portion 202 connected to the hinge shaft 203 is fixed within the groove 201. The torsion spring winding portion 202 is coaxial with the hinge shaft 203. The operating portion 22 has a mounting groove 220 that penetrates its opposing surface and communicates with the lock cavity 10.

[0053] Reference Figure 1 , Figure 4 , Figure 9 , Figure 10 and Figure 12 The latch 3 is hinged to the operating part 22 of the lock body 2 via a hinge pin 330, which is keyed to the mounting hole 33 on the latch 3. A pressing part 30 is integrally connected to the first end of the latch 3, located within a mounting groove 220. The rotation of the pressing part 30 is limited by a limiting part 221 within the mounting groove 220, preventing excessive rotation of the pressing part 30 around the hinge pin 330 and affecting its usability. A locking part 31, capable of locking with the locking groove 11, is integrally connected to the second end of the latch 3; the pressing part 30 is used to disengage the locking part 31 from the locking groove 11. Furthermore, a driving part 32 is integrally connected to the second end of the latch 3, used to drive the locking part 31 out of the locking groove 11.

[0054] Reference Figure 4 and Figure 13 The torsion spring 4 includes a coil portion 40 disposed on the hinge portion 20, a first shaft portion 41 connected and fixed to the latch 3, and a second shaft portion 42 connected and fixed to the lock housing 1. Specifically, the coil portion 40 is sleeved on the torsion spring winding portion 202 of the hinge portion 20; the second shaft portion 42 of the torsion spring 4 is fixed on the torsion spring fixing portion 101 inside the lock cavity 10.

[0055] Reference Figure 1 , Figure 2 , Figure 4 and Figure 5The pressing component 5 is slidably disposed on the side of the lock housing 1 facing away from the operating part 22. The pressing component 5 is used to push the driving part 32 of the bolt 3, causing the locking part 31 to disengage from the locking groove 11. When the locking part 31 is locked to the locking groove 11, the torsion spring 4 is in a stored-energy state. When the pressing part 30 or the pressing component 5 is pressed to unlock the locking part 31, the lock body 2 rotates around the lock housing 1 under the kinetic energy provided by the torsion spring 4, causing the operating part 22 to open the lock cavity 10 and the locking part 21 to unlock.

[0056] As an application scenario, when the push-button lock of this embodiment is installed on the cargo bed cover of a pickup truck, the mounting base 12 is fixedly installed on the cargo bed cover, and the pressing part 30 is located outside the pickup truck cargo bed, while the pressing component 5 is located inside the pickup truck cargo bed. When the lock is in the locked state, the locking part 31 of the latch 3 engages with the locking groove 11, the torsion spring 4 is in a stored state, the operating part 22 covers the lock cavity 10, and the locking part 21 is in a locked state. When it is necessary to unlock the lock from the outside, pressing the pressing part 30 of the lock causes the latch 3 to rotate, thus unlocking the latch 3. The locking part 31 disengages from the locking groove 11, and the lock body 2 rotates around the lock shell 1 under the kinetic energy provided by the torsion spring 4, causing the operating part 22 to open the lock cavity 10 and the locking part 21 to unlock, thereby completing the action of unlocking the lock from the outside; when it is necessary to unlock the lock from the inside, by pressing the pressing part 5 of the lock, the driving part 32 of the bolt 3 is pushed, causing the locking part 31 of the bolt 3 to disengage from the locking groove 11, and the lock body 2 rotates around the lock shell 1 under the kinetic energy provided by the torsion spring 4, causing the operating part 22 to open the lock cavity 10 and the locking part 21 to unlock, thereby completing the action of unlocking the lock from the inside.

[0057] Therefore, it can be seen that the push-button lock of this utility model can be unlocked by pressing from the outside or from the inside, overcoming the defect of existing push-button locks that can usually only be unlocked by pressing from the outside and cannot be unlocked by pressing from the inside.

[0058] It should be noted that the locking state of the lock refers to the state in which the locking part 31 of the bolt 3 is engaged with the locking groove 11, and the unlocking state of the lock refers to the state in which the locking part 31 of the bolt 3 is disengaged from the locking groove 11.

[0059] In this embodiment, refer to Figure 2 , Figure 4 and Figure 5The pressing component 5 includes a pressing rod 50 and a pressing head 51. The outer diameter of the pressing head 51 is larger than the outer diameter of the pressing rod 50. The first end of the pressing rod 50 extends into the lock cavity 10, and the second end of the pressing rod 50 is located outside the lock cavity 10. The pressing rod 50 can slide relative to the lock housing 1. The pressing head 51 is located at the second end of the pressing rod 50 and is used to press the pressing rod 50 to slide relative to the lock housing 1, thereby driving the locking part 31 out of the locking groove 11. Therefore, when it is necessary to unlock the lock from the inside, pressing the pressing rod 50 pushes the driving part 32 of the bolt 3, thereby driving the locking part 31 out of the locking groove 11.

[0060] In addition, refer to Figure 4 , Figure 5 , Figure 11 and Figure 12 The first end of the pressing rod 50 is provided with a limiting part 501 located within the lock cavity 10. The limiting part 501 is coaxially arranged with the pressing rod 50 and is used to prevent the pressing rod 50 from disengaging from the lock cavity 10, thereby facilitating the pressing rod 50 to drive the locking part 31 out of the locking groove 11. In addition, the first end of the pressing rod 50 is provided with a tapered structure 502, and the driving part 32 is provided with an inclined surface 320 facing the pressing rod 50. The tapered surface of the tapered structure 502 is used to slide and adapt to the inclined surface 320. When the pressing rod 50 is manually pushed to move towards the driving part 32, the force exerted by the tapered surface of the tapered structure 502 on the inclined surface 320 causes the locking tongue 3 to rotate around the hinge axis 330, thereby causing the locking part 31 to disengage from the locking groove 11.

[0061] In order to enable the push rod 50 to automatically reset, a push rod reset assembly is provided on the lock housing 1.

[0062] In this embodiment, refer to Figure 2 and Figure 5 The push-button reset assembly includes a mounting plate 52, a spring 53, and a sleeve 54. The mounting plate 52 is fixed to the lock housing 1 with screws. The sleeve 54 is fixed to the mounting plate 52 along its thickness direction. The first end of the push-button 50 slides axially through the sleeve 54 and mounting plate 52 into the lock cavity 10. A positioning part 503 is fitted onto the push-button 50 and located within the sleeve 54, coaxial with the push-button 50. The spring 53 is fitted onto the push-button 50, located within the sleeve 54, with both ends abutting against the mounting plate 52 and the positioning part 503, respectively. When the user presses the push-button 51 inside (in the pickup truck bed), causing the push-button 50 to push the driving part 32 of the latch 3, disengaging the locking part 31 from the locking groove 11, the push-button 50 resets under the elastic force of the spring 53.

[0063] In this embodiment, refer to Figure 1 , Figure 4 , Figure 5 and Figure 14 The lock cylinder 6 is rotatably mounted on the operating part 22 of the lock body 2. The lock cylinder 6 is a commonly used key lock cylinder 6, which is used to prevent or unlock the locking part 31 of the bolt 3 from disengaging from the locking groove 11. The lock cylinder 6 is provided with an unlocking groove 60. When the lock cylinder 6 is rotated by the key, so that the unlocking groove 60 on the lock cylinder 6 faces the corresponding driving part 32, the lock cylinder 6 does not block the rotation of the driving part 32, so the lock cylinder 6 is in the unlocked state; when the lock cylinder 6 is rotated by the key, so that the unlocking groove 60 on the lock cylinder 6 is misaligned with the driving part 32, that is, the peripheral wall of the lock cylinder 6 blocks the rotation of the driving part 32, so the lock cylinder 6 is in the locked state.

[0064] It should be noted that when the lock cylinder 6 is in the unlocked state, it means that the lock cylinder 6 does not prevent the locking part 31 from disengaging from the locking groove 11; when the lock cylinder 6 is in the locked state, it means that the lock cylinder 6 prevents the locking part 31 from disengaging from the locking groove 11.

[0065] When the lock cylinder 6 is in the locked state, the lock tongue 3 cannot be rotated whether the pressing part 30 is pressed from the outside or the pressing rod 50 is pressed from the inside. That is, the locking part 31 of the lock tongue 3 cannot be disengaged from the locking groove 11, so the lock of this embodiment cannot be unlocked.

[0066] In this embodiment, refer to Figure 4 , Figure 5 and Figure 15 The locking knob 7 is rotatably mounted on the lock housing 1 via a bearing. The locking knob 7 is located on the side of the lock housing 1 facing away from the operating part 22. The locking knob 7 is used to prevent the locking part 31 of the bolt 3 from disengaging from the locking groove 11. The locking knob 7 and the lock cylinder 6 are independent of each other. When the locking knob 7 prevents the locking part 31 of the bolt 3 from disengaging from the locking groove 11, the lock cylinder 6 cannot unlock the locking part 31 of the bolt 3 from disengaging from the locking groove 11. That is, when the locking part 31 of the bolt 3 is locked from the inside by the locking knob 7, pressing the pressing part 30 of the lock and rotating the lock cylinder 6 by the key from the outside will also prevent the locking part 31 of the bolt 3 from disengaging from the locking groove 11.

[0067] The first end of the locking knob 7 is located inside the lock cavity 10, and the second end of the locking knob 7 is located outside the lock cavity 10. When the second end of the locking knob 7 is rotated, the second end of the locking knob 7 is configured as a knob part 702. When the first end of the locking knob 7 abuts against the driving part 32, the locking knob 7 is in a locked state. When the second end of the locking knob 7 is rotated, the first end of the locking knob 7 is misaligned with the driving part 32, the locking knob 7 is in an unlocked state. Specifically, the locking knob 7 has a locking block 70 at its first end. The locking block 70 has a square structure and a locking end 701. When the second end of the locking knob 7 is manually rotated, the locking end 701 on the locking block 70 rotates towards the driving part 32 of the bolt 3. The locking block 70 of the locking knob 7 blocks the rotation of the driving part 32 of the bolt 3. At this time, whether the pressing part 30 is pressed from the outside or the pressing rod 50 is pressed from the inside, the bolt 3 cannot be driven to rotate, that is, the locking part 31 cannot be unlocked from the locking groove 11. Even if the lock cylinder 6 is in the unlocked state, pressing the pressing part 30 from the outside cannot drive the bolt 3 to rotate, that is, the locking part 31 cannot be unlocked from the locking groove 11. In this case, the locking knob 7 can only be unlocked from the inside by pressing the pressing rod 50 to unlock the locking part 31 from the locking groove 11.

[0068] It should be noted that when the locking knob 7 is in the locked state, it means that the locking end 701 of the locking knob 7 is facing the driving part 32 of the bolt 3, so that the locking block part 70 of the locking knob 7 blocks the bolt 3 from rotating; when the locking knob 7 is in the unlocked state, it means that the locking end 701 of the locking knob 7 is misaligned with the driving part 32 of the bolt 3, and the locking block part 70 does not block the bolt 3 from rotating.

[0069] In addition, finger gripping portions 703 are provided on opposite sides of the second end of the locking knob 7, which make it easy for the user to grip the locking knob 7 and rotate it.

[0070] The working principle of this push-button lock:

[0071] With both the lock cylinder 6 and the locking knob 7 in the locked state, pressing the pressing part 30 of the lock from the outside or pressing the pressing rod 50 of the lock from the inside will rotate the bolt 3, causing the locking part 31 of the bolt 3 to disengage from the locking groove 11. At this time, the lock body 2 rotates around the lock case 1 under the kinetic energy provided by the torsion spring 4. The bolt 3 and the lock cylinder 6 also rotate with the lock body 2, causing the operating part 22 to open the lock cavity 10 and the locking part 21 to unlock, thus completing the unlocking action of the lock. When it is necessary to lock the lock, the user manually pushes the operating part 22 of the lock body 2 from the outside, causing the lock body 2 to rotate around the hinge axis 203. The bolt 3 and the lock cylinder 6 also rotate with the lock body 2 until the locking part 31 on the bolt 3 is engaged in the locking groove 11, thus completing the locking action of the lock.

[0072] In summary, the push-button lock of this utility model can be unlocked by pressing from the outside or from the inside. Externally, the locking part 31 of the bolt 3 can be locked or unlocked by rotating the lock cylinder 6 with the key to disengage it from the locking groove 11. Internally, the locking part 31 of the bolt 3 can be locked or unlocked by the locking knob 7 to disengage it from the locking groove 11. When the locking part 31 of the bolt 3 is locked from the locking groove 11 by the locking knob 7 internally, pressing the pressing part 30 of the lock externally or rotating the lock cylinder 6 with the key will not unlock the locking part 31 of the bolt 3 from the locking groove 11, thus greatly improving the security performance of the lock.

[0073] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural or procedural transformations made based on the content of the present utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present utility model.
