Description

Technical Field

[0001] This utility model relates to the field of clamping technology, and in particular to a clamping fixture for assembling furniture concealed locks. Background Technology

[0002] Casement window concealed locks are a type of lock installed between the casement window sash and the window frame. By embedding core components such as the lock body, lock plate, and bolt inside the window profile, they ensure the window's locking function while avoiding the aesthetic problems associated with traditional exposed locks. They are widely used in high-end furniture and architectural doors and windows. The assembly of this type of lock requires the precise alignment and fixing of multiple disparate components such as the lock plate, transmission rod, and bolt, followed by assembly using screws and other connectors. This process demands high precision and stability in the positioning of each component.

[0003] In existing assembly processes, due to the small size and irregular shape of lock components, most steps require manual support and fixation of the lock plate and related components. This is not only labor-intensive but also prone to component displacement due to hand tremors, affecting assembly accuracy. Although mechanical clamps are used to assist in fixation in some production processes, existing clamps are mostly manual tightening structures or large electronically controlled structures, making the adjustment process cumbersome. In addition, the clamp model needs to be readjusted every time a different lock model is changed, which is inconvenient and has a long assembly cycle, making it difficult to meet the needs of efficient and mass production. Therefore, this utility model proposes a clamp for assembling furniture concealed locks to solve the problems existing in the prior art. Utility Model Content

[0004] To address the aforementioned problems, this utility model proposes a clamp for assembling concealed furniture locks. This clamp achieves quick clamping via a foot pedal, making operation convenient and efficient.

[0005] To achieve the purpose of this utility model, the utility model is implemented through the following technical solution: a clamp for assembling a furniture concealed lock, including a bracket and a support. The support is disposed above the bracket, and a footrest is elastically hinged to the lower part of one end of the bracket. Pull arms are hinged to both sides of the footrest, and a central shaft is provided between the upper parts of the two sets of pull arms. A first hinge arm is hinged to one end of the central shaft, and a second hinge arm is hinged to the other end of the central shaft. One end of the first hinge arm is hinged to the support, and a sliding sleeve is slidably provided on the other end of the support. One end of the second hinge arm is hinged to the sliding sleeve. An adjusting rod is slidably mounted on one end of the bracket and fixed by a fastener; clamping elements are provided on the sliding sleeve and the adjusting rod.

[0006] A further improvement is that the clamping component includes a first clamping block and a second clamping block, the first clamping block is disposed on the sliding sleeve, the second clamping block is disposed on one end of the adjusting rod, and the inner sides of both the first clamping block and the second clamping block are provided with rubber.

[0007] A further improvement is that a support plate is provided above one end of the bracket, and a through hole is provided below the interior of the second clamping block, with the support plate passing through the through hole.

[0008] A further improvement is that the fixing component includes a base block and a cam, the cam is rotatably located inside the lower part of the base block and a handle is connected to the cam, a push rod is slidably provided inside the upper part of the base block and the lower end of the push rod is supported on the cam, and the upper end of the push rod is provided with a fixing block extending into the bracket.

[0009] A further improvement is that the bottom of the adjusting rod is provided with a fixing tooth, and the upper end of the fixing block is provided with a friction tooth that matches the fixing tooth.

[0010] A further improvement is that: the bottom of the bracket is provided with a chassis, and the inner side of the chassis is provided with an inner frame; the bracket is welded and fixed to the chassis, and the chassis and the inner frame are integrally formed.

[0011] A further improvement is that a reinforcing rib is provided above one end of the bracket, and a bracket is connected above the reinforcing rib.

[0012] A further improvement is that a first hinge lug is provided at the lower end of one end of the bracket, the footrest is hinged to the first hinge lug, and a pedal is provided on the footrest.

[0015] The beneficial effects of this utility model are as follows: 1. This utility model achieves rapid clamping of components such as locking plates by stepping on a foot pedal, which is convenient and efficient. When the foot pedal is stepped on, it drives the pull arms on both sides to move. The pull arms drive the first and second hinge arms to rotate synchronously through the central shaft. Based on the fulcrum at one end of the first hinge arm, the second hinge arm pushes the sliding sleeve to slide along the bracket, so that the first clamping block on the sliding sleeve quickly approaches the second clamping block on the adjusting rod, thereby achieving rapid clamping of components such as locking plates. This structure does not require manual tightening and can be completed by foot movement, freeing the operator's hands, facilitating synchronous assembly operations, effectively shortening the assembly time per operation, and improving production efficiency.

[0019] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.

[0020] according to Figure 1 , 2 As shown in Figure 3, this embodiment proposes a fixture for assembling a furniture concealed lock, including a bracket 1 and a support 2. The support 2 is located above the bracket 1, and a footrest 3 is elastically hinged to the lower part of one end of the bracket 1. Pull arms 4 are hinged to both sides of the footrest 3, and a central shaft 5 is provided between the upper parts of the two sets of pull arms 4. A first hinge arm 6 is hinged to one end of the central shaft 5, and a second hinge arm 7 is hinged to the other end of the central shaft 5. One end of the first hinge arm 6 is hinged to the support 2, and a sliding sleeve 8 is slidably provided on the other end of the support 2. One end of the second hinge arm 7 is hinged to the sliding sleeve 8.

[0021] One end of the bracket 2 is slidably mounted with an adjusting rod 9 and fixed by a fastener. The sliding sleeve 8 and the adjusting rod 9 are provided with clamping components.

[0022] During operation, by stepping on the foot pedal 3, the foot pedal 3 rotates around the hinge point and drives the pull arm 4 to move. The pull arm 4 drives the first hinge arm 6 and the second hinge arm 7 to rotate synchronously through the central shaft 5. The second hinge arm 7 pushes the sliding sleeve 8 to slide along the bracket 2, so that the clamping part on the sliding sleeve 8 approaches the clamping part on the adjusting rod 9, thereby clamping the component. When the foot pedal 3 is released, the elastic force drives it to reset, and the components move in the opposite direction, and the clamping part is released.

[0023] The clamping component includes a first clamping block 10 and a second clamping block 11. The first clamping block 10 is disposed on the sliding sleeve 8, and the second clamping block 11 is disposed on one end of the adjusting rod 9. Both the first clamping block 10 and the second clamping block 11 are provided with rubber on their inner sides.

[0024] During operation, the sliding sleeve 8 drives the first clamping block 10 to move, which cooperates with the second clamping block 11 fixed on the adjusting rod 9. The components are clamped by the rubber on the inner side of the two. The rubber can prevent the components from being damaged by the clamping, and at the same time increase the friction to prevent the components from sliding.

[0025] A support plate 12 is provided on the upper part of one end of the bracket 2, and a through hole 13 is provided on the lower part of the second clamping block 11, through which the support plate 12 passes. By providing the support plate 12, the component to be clamped can be supported. The second clamping block 11 moves along the support plate 12 through the through hole 13, ensuring that the second clamping block 11 does not deviate from the support surface when adjusted, thus improving the stability of the component during clamping.

[0026] The fixing component includes a base block 15 and a cam 16. The cam 16 is rotatably located inside the lower part of the base block 15, and a handle 17 is connected to the cam 16. A push rod 18 is slidably located inside the upper part of the base block 15, and the lower end of the push rod 18 is supported on the cam 16. The upper end of the push rod 18 is provided with a fixing block 19 extending into the bracket 2. The working principle of the fixing component is as follows: by rotating the handle 17, the cam 16 is driven to rotate. The protruding part of the cam 16 pushes up the push rod 18, causing the push rod 18 to drive the fixing block 19 to move upward and press the adjusting rod 9, thereby fixing the adjusting rod 9. When the handle 17 is rotated in the opposite direction, the cam 16 returns to its original position, the push rod 18 and the fixing block 19 move downward, and the adjusting rod 9 can slide freely.

[0027] The bottom of the adjusting rod 9 is provided with fixing teeth 14, and the upper end of the fixing block 19 is provided with friction teeth that are adapted to the fixing teeth 14. When the fixing block 19 moves upward, the friction teeth at its upper end mesh with the fixing teeth 14 at the bottom of the adjusting rod 9. The meshing of the teeth enhances the friction between the fixing block 19 and the adjusting rod 9, preventing the adjusting rod 9 from sliding during clamping and improving the reliability of the fixation.

[0028] The support 1 has a base plate 20 at its bottom, and an inner frame 21 is provided on the inner side of the base plate 20. The support 1 is welded and fixed to the base plate 20, and the base plate 20 and the inner frame 21 are integrally formed. The base plate 20 increases the contact area between the support 1 and the ground, and the inner frame 21 enhances the structural strength of the base plate 20. The two work together to improve the overall stability of the clamp and prevent the clamp from tipping over or shaking during clamping operations.

[0029] A reinforcing rib 22 is provided above one end of the bracket 1, and the bracket 2 is connected above the reinforcing rib 22. The reinforcing rib 22 connects the bracket 1 and the bracket 2, and enhances the connection strength between the two through a triangular stabilizing structure, reduces the deformation of the bracket 2 under stress, and improves the structural rigidity of the clamp.

[0030] The bracket 1 has a first hinge lug 23 at one end, and the footrest 3 is hinged to the first hinge lug 23. The footrest 3 is also equipped with a pedal 24. The first hinge lug 23 provides a pivot point for the footrest 3, ensuring that the footrest 3 can rotate flexibly around it. The pedal 24 increases the contact area between the foot and the footrest 3, making it easier for the operator to step on and apply force, thus improving the ease of operation.

[0031] A second hinge 25 is provided on the bracket 1 located above the first hinge ear 23, and a connecting shaft is provided on the second hinge ear 25. A spring 26 is connected between the connecting shaft and the foot pedal 3. When the foot pedal 3 is stepped on, the spring 26 is stretched and stores force; after the foot pedal is released, the elastic force of the spring 26 pulls the foot pedal 3 to rotate in the opposite direction around the first hinge ear 23, so that the foot pedal 3 returns to its initial position, preparing for the next clamping.

[0032] The bracket 2 has a hinge seat 27 at one end of its top. One end of the first hinge arm 6 is hinged to the hinge seat 27. The sliding sleeve 8 has a third hinge ear 28, and one end of the second hinge arm 7 is hinged to the third hinge ear 28. The hinge seat 27 provides a fixed rotation fulcrum for the first hinge arm 6, ensuring that the first hinge arm 6 can rotate stably. The third hinge ear 28 provides a rotation fulcrum for the second hinge arm 7, allowing it to move with the sliding sleeve 8, so that the second hinge arm 7 can smoothly push the sliding sleeve 8 to slide along the bracket 2, ensuring the stability of the transmission mechanism.

[0033] This furniture concealed lock assembly clamp achieves rapid clamping of components such as the lock plate by stepping on the foot pedal 3. The operation is convenient and efficient. When the foot pedal 3 is stepped on, the foot pedal 3 drives the pull arms 4 on both sides to move. The pull arms 4 drive the first hinge arm 6 and the second hinge arm 7 to rotate synchronously through the central shaft 5. Based on the fulcrum at one end of the first hinge arm 6, the second hinge arm 7 pushes the sliding sleeve 8 to slide along the bracket 2, so that the first clamping block 10 on the sliding sleeve 8 quickly approaches the second clamping block 11 on the adjusting rod 9, thereby achieving rapid clamping of components such as the lock plate. This structure does not require manual tightening. The clamping can be completed by stepping on the foot, freeing the operator's hands, facilitating synchronous assembly operations, effectively shortening the assembly time per cycle, and improving production efficiency. Furthermore, this product features flexible adjustment capabilities and strong adaptability. The adjusting rod 9 can slide along the bracket 2 to change the initial position of the second clamping block 11. After adjustment, the cam 16 is rotated by turning the handle 17. The cam 16 pushes up the top rod 18, causing the friction teeth on the fixed block 19 to mesh with the fixed teeth 14 at the bottom of the adjusting rod 9, thereby firmly fixing the adjusting rod 9. This design allows the clamping stroke and range of the clamp to be flexibly adjusted according to the size of different models of lock components. It can meet the assembly needs of various specifications of products without changing the clamp, reducing equipment replacement costs and enhancing the versatility of the clamp.
