Description

Technical Field

[0001] This utility model relates to the field of production operation technology, and in particular to a special nail gun for zipper pulls. Background Technology

[0002] As an indispensable piece of furniture in modern homes and commercial spaces, the comfort, durability, and internal structure of sofas are closely related to the design and installation of the seat cushion support system. A crucial step in sofa manufacturing is installing and tensioning the elastic bands (also known as webbing) that support the foam seat cushions onto the sofa's wooden or metal frame. The quality of this process directly determines the cushion's support, resilience, and ability to maintain its shape over long-term use, making it a vital factor affecting the overall quality and user experience of the sofa.

[0003] Currently, the commonly used elastic band fixing process in the industry is as follows: The operator first uses a pneumatic or electric nail gun to initially fix one end of the elastic band to a predetermined position on the sofa's bottom frame. Then, the operator must use one hand (usually the non-dominant hand) to forcefully pull the other end of the elastic band, creating sufficient elastic deformation and tension, ensuring the elastic band is pulled past the predetermined fixing point on the other end of the bottom frame. In this state, the operator must use their other hand (dominant hand) to hold the nail gun, aim at the fixing position, and press the trigger, thus triggering the nailing action and completing the final fixing of the other end of the elastic band.

[0004] However, the existing process has significant drawbacks. The core problem lies in the fact that tightening the elastic band and the nailing action of the nail gun are two completely separate, unlinked steps. The firing of the nail gun relies entirely on the worker's manual, instantaneous triggering action. This presents the worker with a significant challenge: they must simultaneously apply and maintain tension on the elastic band with one hand, accurately judge the optimal moment for nailing, and operate the nail gun while being distracted.

[0005] Because the tension of the elastic band and the timing of nailing rely entirely on the worker's personal feel and experience, it is difficult for different workers, or even the same worker, to maintain a uniform tension at different moments. This directly leads to significant differences in the tension of different elastic bands, affecting the standardization and stability of product quality.

[0006] Therefore, existing nail guns need to be improved to solve the problem of poor consistency in elastic band installation caused by the independent separation of their pulling and nailing actions.

[0007] The information disclosed in this background section is included only to enhance the understanding of the context of this disclosure, and therefore may contain information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0008] One objective of this invention is to provide a special nail gun for elastic bands, which can solve the problem that the existing nail guns have separate pulling and nailing actions, resulting in poor consistency in elastic band installation.

[0009] To achieve the above objectives, this utility model provides a special nail gun for zip ties, comprising:

[0010] The nail gun body includes a nail outlet and a trigger assembly for controlling the nail outlet to eject the nail;

[0011] A sliding clamp, located below the nail gun outlet and slidably connected to the nail gun body, is used to clamp the elastic band to be tightened;

[0012] A detection mechanism is located at the end of the sliding clamp away from the nail outlet and is electrically connected to the trigger assembly, for triggering the trigger assembly to control the nail outlet to eject when the sliding clamp is detected.

[0013] Optionally, the trigger assembly includes:

[0014] A rotary trigger, rotatably mounted on the nail gun body, is used to control the nail ejection from the nail outlet;

[0015] An electric latching mechanism is installed inside the nail gun body, and the drive end of the electric latching mechanism is connected to the rotary trigger; the electric latching mechanism is electrically connected to the detection mechanism and is used to trigger the rotary trigger by the detection mechanism.

[0016] Optionally, the electric latch mechanism includes:

[0017] An electric rotary wheel is located inside the nail gun body and is electrically connected to the detection mechanism.

[0018] A pull rope, one end of which is fixed to the electric rotary wheel, and the other end of which is connected to the rotary trigger;

[0019] A trigger return spring is sleeved on the pull rope and abuts against the side of the rotating trigger near the electric rotary wheel, used to drive the rotating trigger to rotate away from the electric rotary wheel.

[0020] Optionally, the sliding clamp includes:

[0021] A sliding clamp plate, wherein the sliding clamp plate has a slider part on the side near the nail gun body that is slidably connected to the nail gun body and is positioned opposite the detection mechanism;

[0022] A vertical torsion spring shaft is located in the middle of the sliding clamp;

[0023] A rotating clamp is located on the side of the sliding clamp away from the nail gun body and is rotatably connected to the sliding clamp via the vertical torsion spring shaft.

[0024] The vertical torsion spring shaft is used to provide preload, so that the clamping ends of the two clamping plates come close to each other to clamp the elastic band.

[0025] Optionally, both clamping ends are provided with anti-slip pins for insertion into cable ties.

[0026] Optionally, a reset positioning block is fixed on the nail gun body. The reset positioning block is located on the side of the slider that is away from the detection mechanism, and is used to restrict the slider from continuing to slide away from the detection mechanism.

[0027] Optional, also includes:

[0028] A clamp reset spring is located on the side of the slider portion away from the detection mechanism, and is used to drive the slider portion to slide away from the detection mechanism until it abuts against the reset positioning block.

[0029] Optionally, the detection mechanism is a limit switch.

[0030] Optionally, the detection mechanism is a ranging sensor;

[0031] The outer surface of the nail gun body is also fixedly equipped with a display screen electrically connected to the testing mechanism, which is used to display graphic and textual information representing the testing results of the testing mechanism in real time.

[0032] Optionally, the sliding clamp is provided with guide sleeves above and / or below for the elastic band to pass through.

[0033] The beneficial effects of this utility model are as follows: It provides a special nail gun for zip ties, and the usage process is as follows:

[0034] (1) The operator first fixes one end of the elastic band to one end of the sofa bottom frame, and then pulls the other end of the elastic band until it passes over the other end of the sofa bottom frame;

[0035] (2) Next, the operator aligns the nail gun outlet with the connection point between the elastic band and the other end of the sofa frame; then, the operator opens the sliding clamp and puts the elastic band into the sliding clamp to clamp it (at this time, the sliding clamp is in the initial position away from the detection mechanism).

[0036] (3) The operator holds the nail gun body with one hand (non-dominant hand) and pulls the elastic band with the other hand (dominant hand) to make the sliding clamp slide along the nail gun body. When the sliding clamp slides to the detection area of ​​the detection mechanism, the detection mechanism detects the presence of the sliding clamp and sends an electrical signal to trigger the trigger assembly.

[0037] (4) The trigger assembly then controls the nail outlet to eject the nail, fixing the other end of the elastic band to the bottom frame of the sofa.

[0038] The pull-belt nail gun provided by this utility model achieves automatic linkage between tightening the elastic band and nailing actions by setting up a trigger assembly, a sliding clamp, and a detection mechanism. When the elastic band is pulled, causing the sliding clamp to slide to a predetermined position, the detection mechanism automatically triggers the trigger assembly to perform the nailing operation, ensuring that the tension of the elastic band is consistent each time a nail is driven. This solves the problem of poor work consistency caused by the independent separation of the pull-belt action and the nailing action, improves the standardization and stability of product quality, and reduces reliance on manual operation experience.

[0057] This utility model provides a special nail gun for elastic bands, which can solve the problem that the existing nail guns have separate pulling action and nailing action, resulting in poor consistency in elastic band installation.

[0058] See Figure 1 The zipper-specific nail gun provided in this embodiment includes:

[0059] The nail gun body 1 includes a nail outlet 101 and a trigger assembly for controlling the nail outlet 101 to dispense nails.

[0060] A sliding clamp 3 is located below the nail gun outlet 101 and is slidably connected to the nail gun body 1 for clamping the elastic band 100 to be tightened.

[0061] The detection mechanism 4 is located at one end of the sliding clamp 3 away from the nail outlet 101 and is electrically connected to the trigger assembly. It is used to trigger the trigger assembly to control the nail outlet 101 to eject the nail when the sliding clamp 3 is detected.

[0062] Furthermore, the trigger assembly includes:

[0063] A rotary trigger 102 is rotatably mounted on the nail gun body 1 and is used to control the nail outlet 101 for nail dispensing;

[0064] An electric latching mechanism 104 is installed inside the nail gun body 1, and the drive end of the electric latching mechanism 104 is connected to the rotary trigger 102; the electric latching mechanism 104 is electrically connected to the detection mechanism 4, and is used to trigger the rotary trigger 102 by the detection mechanism 4.

[0065] It should be noted that the specific structure of nailing by pulling the rotating trigger 102 is existing technology, and the detailed structure and principle will not be described in detail.

[0066] When using a zip tie nail gun, the process is as follows:

[0067] (1) The operator first fixes one end of the elastic band 100 to one end of the sofa bottom frame, and then pulls the other end of the elastic band 100 until it passes over the other end of the sofa bottom frame;

[0068] (2) Next, the operator aligns the nail outlet 101 with the connection position of the elastic band 100 and the other end of the sofa bottom frame; then, the operator opens the sliding clamp 3 and puts the elastic band 100 into the sliding clamp 3 to clamp it (at this time, the sliding clamp 3 is in the initial position away from the detection mechanism 4).

[0069] (3) The operator holds the nail gun body 1 with one hand (non-dominant hand) and pulls the elastic band 100 with the other hand (dominant hand) to make the sliding clamp 3 slide along the nail gun body 1. When the sliding clamp 3 slides to the detection area of ​​the detection mechanism 4, the detection mechanism 4 detects the presence of the sliding clamp 3 and sends an electrical signal to trigger the electric latch mechanism 104.

[0070] (4) The drive end of the electric buckle mechanism 104 is connected to the rotary trigger 102. Then, the rotary trigger 102 is pulled to control the nail outlet 101 to release the nail and fix the other end of the elastic band 100 to the bottom frame of the sofa.

[0071] The pull-belt nail gun provided by this utility model achieves automatic linkage between tightening the elastic band 100 and the nailing action by setting up a sliding clamp 3, a detection mechanism 4, and an electric latching mechanism 104. When the elastic band 100 is pulled so that the sliding clamp 3 slides to a predetermined position, the detection mechanism 4 automatically triggers the electric latching mechanism 104 to pull the rotating trigger 102, ensuring that the tension of the elastic band 100 is consistent each time a nail is driven. This solves the problem of poor work consistency caused by the independent separation of the pull-belt action and the nailing action, improves the standardization and stability of product quality, and reduces the reliance on manual operation experience.

[0072] In this embodiment, the electric latch mechanism 104 includes:

[0073] An electric rotary wheel 1041 is located inside the nail gun body 1 and is electrically connected to the detection mechanism 4.

[0074] A pull rope 1042, one end of which is fixed to the electric rotary wheel 1041, and the other end is connected to the rotary trigger 102;

[0075] A trigger return spring 1043 is sleeved on the pull rope 1042 and abuts against the side of the rotary trigger 102 near the electric wheel 1041, for driving the rotary trigger 102 to rotate away from the electric wheel 1041.

[0076] When the detection mechanism 4 sends an electrical signal, the electric rotary wheel 1041 rotates, pulling the pull rope 1042, thereby pulling the rotary trigger 102. When the electric rotary wheel 1041 releases the pull rope 1042, the trigger reset spring 1043 drives the rotary trigger 102 to rotate away from the electric rotary wheel 1041, thereby achieving automatic reset of the rotary trigger 102.

[0077] Furthermore, the sliding clamp 3 includes:

[0078] A sliding clamp 301 is provided on the side of the sliding clamp 301 near the nail gun body 1, and a slider part 3011 is provided that is slidably connected to the nail gun body 1 and is disposed opposite to the detection mechanism 4;

[0079] A vertical torsion spring shaft 302 is located in the middle of the sliding clamp 301;

[0080] Rotate clamping plate 303, which is located on the side of sliding clamping plate 301 away from the nail gun body 1, and is rotatably connected to sliding clamping plate 301 through vertical torsion spring shaft 302;

[0081] The vertical torsion spring shaft 302 is used to provide preload, so that the clamping ends of the two clamping plates come close to each other to clamp the elastic band 100.

[0082] Optionally, both clamping ends are provided with anti-slip pins 304 for insertion into cable ties.

[0083] When the elastic band 100 needs to be clamped, the operator opens the rotating clamp 303 (overcoming the preload of the vertical torsion spring shaft 302) and places the elastic band 100 between the sliding clamp 301 and the rotating clamp 303. After opening, the vertical torsion spring shaft 302 provides preload, bringing the clamping ends of the two clamps closer together to clamp the elastic band 100. At this time, the anti-slip pin 304 is inserted into the elastic band 100, effectively preventing the elastic band 100 from slipping or coming out during the tightening process, enhancing the stability and reliability of the clamping, and ensuring that the tension force is transmitted evenly.

[0084] In this embodiment, a reset positioning block 103 is fixed on the nail gun body 1. The reset positioning block 103 is located on the side of the slider part 3011 away from the detection mechanism 4, and is used to restrict the slider part 3011 from continuing to slide away from the detection mechanism 4.

[0085] The zipper nail gun also includes a clamp reset spring 5, which is located on the side of the slider 3011 away from the detection mechanism 4, and is used to drive the slider 3011 to slide away from the detection mechanism 4 until it abuts against the reset positioning block 103.

[0086] When the elastic band 100 is pulled, the sliding clamp 3 slides along the nail gun body 1 via the slider part 3011 until it is detected by the detection mechanism 4. After the sliding clamp 3 slides to the position of the detection mechanism 4 and completes nailing, the operator releases the elastic band 100, and the clamp reset spring 5 drives the slider part 3011 to slide away from the detection mechanism 4 until the slider part 3011 abuts against the reset positioning block 103, thereby realizing the automatic reset of the sliding clamp 3.

[0087] As an optional implementation, the detection mechanism 4 is a limit switch. When the sliding clamp 3 slides into the detection area, the slider part 3011 touches the limit switch, triggering the limit switch to send an electrical signal to the electric latching mechanism 104.

[0088] Alternatively, the detection mechanism 4 can be a distance sensor. The distance sensor detects the distance between the sliding clamp 3 (such as the slider part 3011) and the sensor in real time; when the distance reaches a preset value, the distance sensor sends an electrical signal to trigger the electric latch mechanism 104. Furthermore, a display screen 6 electrically connected to the detection mechanism 4 is fixedly installed on the outer surface of the nail gun body 1, for displaying graphic and textual information representing the detection results of the detection mechanism 4 in real time.

[0089] Optionally, the display screen 6 can directly display the distance information detected by the detection mechanism 4, or it can calculate the specific tension by combining the preset elastic modulus of the elastic band 100 with the real-time detected distance information, and then display the tension so that the worker can choose the timing to manually pull the rotating trigger 102 according to the tension value when necessary.

[0090] In this embodiment, a guide sleeve 2 is provided above and / or below the sliding clamp 3 for the elastic band 100 to pass through. During operation, the elastic band 100 passes through the guide sleeve 2, which guides the direction of the elastic band 100, ensuring it maintains the correct direction during tightening. This prevents the elastic band 100 from deviating, twisting, or tangling during tightening, ensuring uniform tension and improving operational smoothness and safety.

[0091] Finally, it should be noted that although the above embodiments have been described in the text and drawings of this application, this should not limit the scope of patent protection of this application. Any technical solutions that are based on the essential concept of this application and utilize the content described in the text and drawings of this application, resulting in equivalent structural or procedural substitutions or modifications, as well as the direct or indirect application of the technical solutions of the above embodiments to other related technical fields, are all included within the scope of patent protection of this application.
