Description

Technical Field

[0001] The utility model relates to the technical field of sealing strip opening tools, and more specifically, to a cutting pliers for opening drainage holes on a sealing strip. Background Art

[0002] In the current rapidly developing automotive industry, as one of the key components, the performance and quality of automotive sealing strips directly affect the sealing performance and durability of vehicles. Among them, the sealing strip used for the automotive trunk mainly plays the roles of sealing and waterproofing. It can effectively prevent external substances such as rainwater and dust from entering the trunk interior, protect the items in the trunk from damage. At the same time, the sealing strip can also reduce wind noise during vehicle driving and improve riding comfort.

[0003] Opening drainage holes on the sealing strip of the automotive trunk is a detail part in automotive design. During long-term use or under extreme weather conditions, the sealing strip may age, be damaged, or have poor sealing, which is likely to cause water infiltration. At this time, the drainage holes play a key role. These drainage holes are usually located at the lowest part of the sealing strip, and it can timely drain this part of the water from the sealing strip to prevent water accumulation in the sealing strip, resulting in a reduced service life of the sealing strip. However, currently, most of the methods for opening drainage holes on the sealing strip are manual cutting with scissors, that is, first draw the contour line of the drainage hole on the sealing strip, and then use scissors to cut out the drainage hole according to the drawn contour line. The drainage holes cut by this method are prone to non-compliant sizes and irregular shapes, and the opening speed is slow and the process is cumbersome.

[0004] Therefore, how to provide a cutting pliers for opening drainage holes on a sealing strip with high opening accuracy, high efficiency, simple operation and convenient use is a technical problem that those skilled in the art need to solve urgently. Summary of the Utility Model

[0005] In view of this, in order to solve the technical problems of slow speed, poor accuracy and cumbersome process in manually cutting drainage holes on the sealing strip in the prior art, the utility model provides a cutting pliers for opening drainage holes on a sealing strip with simple operation, convenient use, high opening accuracy and high efficiency.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0007] The upper clamping arm, lower clamping arm, upper clamping plate, lower clamping plate, clamping shaft, articulated strip plate and handle rod; the upper clamping arm and the lower clamping arm are both strip-shaped blocks and are arranged parallel to each other vertically; one end of the upper clamping plate is connected to the first end of the upper clamping arm, and the middle plate body extends vertically downward to form a cutter; one end of the lower clamping plate is connected to the first end of the lower clamping arm, and a cutting through hole corresponding to the cutter up and down is formed in the middle plate body thereof. Opposite end portions of the upper clamping plate and the lower clamping plate are respectively formed with an upper clamping plate engaging portion and a lower clamping plate engaging portion, and the upper clamping plate engaging portion and the lower clamping plate engaging portion can bite and clamp the sealing strip; the clamping shaft is arranged between the upper clamping arm and the lower clamping arm, and its axis direction is perpendicular to the length direction of the upper clamping arm; the articulated strip plates are two, and the two articulated strip plates are perpendicular to the clamping shaft and are arranged in an X shape. Free end portions of each of the articulated strip plates are respectively fixedly connected to the upper clamping arm and the lower clamping arm, and the central position is rotatably connected to the clamping shaft; the handle rods are two and are respectively fixedly connected to the articulated strip plates corresponding to the second ends of the upper clamping arm and the lower clamping arm.

[0008] Preferably, a cutting pliers for opening a drainage port on a sealing strip further includes connecting blocks. There are two connecting blocks, and the two connecting blocks are respectively formed by extending outward along the length direction from the first ends of the upper clamping arm and the lower clamping arm. An assembly groove is formed at one end of each connecting block away from the clamping shaft, and one ends of the upper clamping plate and the lower clamping plate are respectively fixed in the corresponding assembly grooves.

[0009] Preferably, a cutting pliers for opening a drainage port on a sealing strip further includes a return spring. Spring grooves are formed on opposite wall surfaces of the two connecting blocks, and two ends of the return spring are respectively fixed in the spring grooves of the two connecting blocks.

[0010] Preferably, a shaft connection hole is formed in the center of each of the two articulated strip plates, and the clamping shaft is rotatably connected in the shaft connection holes of the two articulated strip plates.

[0011] Preferably, the articulated strip plates are two groups, and the two groups of articulated strip plates are symmetrically arranged on both sides of the upper clamping arm and the lower clamping arm and are respectively rotatably connected to both ends of the clamping shaft.

[0012] Preferably, one end of each articulated strip plate away from the return spring extends outward along the length direction and is respectively connected to the corresponding handle rod.

[0013] Preferably, the upper clamping plate engaging portion is a horizontal convex surface protruding downward from the upper clamping plate; the lower clamping plate engaging portion is a horizontal concave surface recessed downward from the lower clamping plate.

[0014] Preferably, the cutting through hole is 55 mm long and 6 mm wide.

[0015] As can be seen from the above technical solutions, compared with the prior art, the present utility model discloses a cutting pliers for opening drainage holes on a sealing strip, and its main effects and advantages are as follows:

[0016] 1. Place the sealing strip between the upper clamping plate and the lower clamping plate, hold the two handle rods and apply force. The two hinged strip plates rotate reversely around the pliers shaft driven by the handle rods. The upper pliers arm and the lower pliers arm approach each other. The cutter of the upper clamping plate passes through the sealing strip and enters the cutting through hole of the lower clamping plate. The sealing strip is clamped and positioned by the clamping part of the upper clamping plate and the clamping part of the lower clamping plate. The cutter can cut a drainage notch on the sealing strip that is the same size as the cutting through hole.

[0017] 2. When the device is not in use, the reset spring can make the two connecting blocks move away from each other, so that the upper clamping plate and the lower clamping plate no longer contact each other.

[0018] 3. The pliers shaft is the rotation fulcrum of the two X-shaped hinged strip plates. According to the lever principle, the force applied to the two handle rods is less than the clamping force of the upper clamping plate and the lower clamping plate on the sealing strip, and the device is more labor-saving when in use.

[0019] 4. The device not only cuts the drainage notch on the sealing strip quickly and with high precision, but also has a simple structure, is easy to operate and convenient to carry. BRIEF DESCRIPTION OF THE DRAWINGS
