Description

Technical Field

[0001] This utility model relates to the field of seat cover processing technology, specifically to a surface stitching tooling for processing antibacterial car seat covers. Background Technology

[0002] Car seat covers are exterior fabrics that are fitted onto the seat frame. They are mainly made of artificial leather or animal leather. In order to improve the antibacterial effect and aesthetics of the covers, an antibacterial layer is coated on the leather surface and decorative stitching is added. When adding decorative stitching, edge sewing equipment is mainly used to sew the stitches onto the leather surface.

[0003] For example, Chinese patent document CN218876339U discloses a stitching device for soft-surface automotive interior materials, including a support panel. A first electric slide rail is fixedly connected to both sides of the support panel. A second electric slide rail is mounted on the first electric slide rail via a connecting block. A connecting plate is provided on the front of the second electric slide rail. An L-shaped placement plate for placing the soft-surface automotive interior material is fixedly connected to the front of the connecting plate. Auxiliary positioning mechanisms for limiting the position of the soft-surface automotive interior material are provided on both sides of the L-shaped placement plate. An intelligent sewing machine for stitching the soft-surface automotive interior material is provided on the back of the top of the support panel.

[0004] In the above technical solution, the design of the auxiliary positioning mechanism can fix the plastic film in a secondary manner, which improves the fixing effect of the plastic mold on which the soft surface of the car interior is placed and effectively prevents the plastic mold on which the soft surface of the car interior is placed from shifting during sewing. However, the auxiliary positioning mechanism is mainly fixed by suction cups. Therefore, a certain amount of time needs to be reserved when vacuuming the suction cups, which makes it impossible to quickly fix the leather on the edge to be sewn. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a surface stitching tool for processing antibacterial car seat covers, which can quickly fix the leather during stitching to improve the stitching efficiency of leather.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a surface stitching fixture for processing antibacterial car seat covers, comprising a base plate and a clamp, wherein a protruding support seat is fixed on the base plate, and multiple support seats are arranged around the base plate to form a placement area for placing leather to be stitched, and the clamp is fitted around the outer periphery of the support seat to quickly fix the edge of the leather.

[0007] The present invention is further configured such that: the top of the sleeve is symmetrically provided with a liftable drive rod, the inner wall of the drive sleeve is rotatably connected with a transmission rod, and the lower part of the transmission rod is provided with symmetrically arranged clamping blocks, which are respectively located on both sides of the support base. The transmission rod is raised and lowered by the drive rod to drive the clamping blocks on both sides to move towards each other or away from each other. A spring is fitted on the outer periphery of the drive rod, and the spring is used to provide pressure to the clamping blocks.

[0008] The present invention is further configured such that: the clamping block is provided with a laterally extending rack, the transmission rod is provided with a protruding connecting flange, a connecting rod is provided between the transmission rod and the drive rod, one end of the connecting rod is rotatably connected to the connecting flange, and the other end is rotatably connected to one side end of the drive rod, the transmission rod is provided with transmission teeth on the side away from the connecting flange, the transmission teeth can mesh with the rack, the transmission rod is raised and lowered by the drive rod to rotate, and the clamping block is moved by the meshing transmission teeth and the rack.

[0009] The present invention is further configured such that: the inner wall of the sleeve is provided with a transversely extending guide groove, the outer wall of the clamp is provided with a protruding guide block, and the guide block can be coupled to the guide groove to form a sliding fit between the two.

[0010] The present invention is further configured such that: the two ends of the sleeve are provided with handles for gripping.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] Because multiple clips are provided, each clip contains a clamping block that can be moved up and down via a drive rod. By pressing the drive rod, the clamping blocks on both sides can be moved away from each other for quick release. At this time, the clip can be fitted onto the outer periphery of the support base. After the drive rod is released, the clamping blocks can be reset by the spring to quickly clamp and fix the outer edge of the leather. Therefore, it effectively solves the technical problem that the existing technology of fixing leather by vacuum adsorption requires a long waiting time. This allows for quick fixation of the leather during sewing, thereby improving the sewing efficiency of the leather surface. Attached Figure Description

[0016] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0018] As shown in the figures, this utility model discloses a surface stitching fixture for processing antibacterial car seat covers, including a base plate 1 and a clamp 2. A protruding support seat 3 is fixed on the base plate 1, and the support seats 3 are distributed around the perimeter of the base plate 1, forming a rectangular placement area 100 for supporting the leather 300 to be stitched. The clamp 2 has a U-shaped cross-section and is used to fit around the support seat 3. Internal clamping blocks 6 quickly secure the edges of the leather 300. In practice, the operator first lays the leather 300 to be stitched flat in the placement area 100, extending its edges to the outside of the support seat 3. Then, the clamp 2 is fitted onto the support seat 3 from top to bottom. Pressure is applied to the leather 300 by driving the clamping blocks 6 of the clamp 2 to achieve stable clamping. In addition, pin holes 200 for inserting pin rods are provided around the base plate 1. When the base plate 1 needs to be installed on the sewing machine's worktable, simply align the pin holes 200 with the corresponding holes on the worktable, insert the pin rod, and the base plate 1 can be laterally limited, thus achieving quick installation of the base plate 1.

[0019] Furthermore, two liftable drive rods 4 are symmetrically arranged at the top of the sleeve clamp 2, penetrating the top wall of the sleeve clamp 2 and extending into its interior. Below each drive rod 4 is a transmission rod 5, which is rotatably connected to the inner wall of the support base 3 via a pin. The transmission rod 5 and the drive rod 4 are connected by a connecting rod described below. Below the transmission rod 5 are symmetrically distributed clamping blocks 6, located on both sides of the support base 3. A spring 7 is fitted around the outer periphery of the drive rod 4, with one end of the spring 7 abutting against the top wall of the sleeve clamp 2 and the other end abutting against the top of the drive rod 4, providing continuous clamping force to the clamping blocks 6. When the drive rod 4 is pressed down, the spring 7 compresses and stores force, while the drive rod 4 drives the transmission rod 5 to rotate via the connecting rod. The rotational motion of the transmission rod 5 is converted into lateral linear motion of the clamping blocks 6, causing the two clamping blocks 6 to move away from the edge of the leather 300. When the drive rod 4 is released, the spring 7 rebounds, pushing the drive rod 4 back to its original position, causing the two clamping blocks 6 to move towards each other to clamp the edge of the leather 300.

[0020] Specifically, the structure that converts the rotational motion of the transmission rod 5 into the lateral linear motion of the clamping block 6 is as follows: a laterally extending rack 61 is provided at the top of the clamping block 6; a transmission tooth 52 that meshes with the rack 61 is provided on the side of the transmission rod 5 away from the drive rod 4; and a connecting flange 51 is provided on the other side of the transmission rod 5, which is hinged to one end of the drive rod 4 via a connecting rod. When the drive rod 4 rises and falls, the connecting rod pushes the connecting flange 51, driving the transmission rod 5 to rotate. The meshing of the transmission tooth 52 with the rack 61 further converts the rotational motion into the synchronous horizontal movement of the clamping block 6, ensuring that the clamping force on both sides is evenly distributed. To improve the stability of the movement of the clamping block 6, a laterally extending guide groove 21 is provided on the inner wall of the sleeve 2, and a protruding guide block 62 is provided on the outer wall of the clamping block 6. The guide block 62 is embedded in the guide groove 21 to form a sliding fit, restricting the clamping block 6 to move only in the horizontal direction, avoiding deviation or jamming.

[0021] In addition, the sleeve 2 is equipped with handles 8 at both ends. During operation, the worker can quickly clamp and release the sleeve 2 by pulling or pressing down the handles 8 while simultaneously pressing the drive rod 4. This improves the convenience of single-person operation.

[0022] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
