Description

Technical Field

[0001] This utility model belongs to the field of seat cover manufacturing technology, and more specifically, it relates to a pattern sewing projection auxiliary alignment device. Background Technology

[0002] Seat covers, as bedding products that combine functionality, decoration, and ease of maintenance, are widely used in high-end commercial settings (such as five-star hotels, luxury cruise ships, and high-end clubs) and residential settings (such as custom furniture and infant safety seats). Some high-end seat covers require manual sewing during processing, but the frequent positioning of the covers during sewing leads to low work efficiency. Therefore, a pattern sewing projection-assisted alignment device is needed.

[0003] Existing pattern sewing projection-assisted alignment devices have drawbacks: the projector is not easy to disassemble and assemble quickly, which can affect the maintenance efficiency of the device; and the adjustability of the device needs to be improved, making it difficult to fix seat covers of different sizes as needed. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a pattern sewing projection auxiliary alignment device, which solves the problems of existing similar devices where the projector is inconvenient to quickly disassemble and assemble, easily affecting the maintenance efficiency of the device; and the adjustability of the device needs to be improved, making it inconvenient to fix seat covers of different sizes as needed.

[0005] The pattern sewing projection-assisted alignment device of this utility model is achieved by the following specific technical means: A pattern sewing projection-assisted alignment device includes a work frame; A set of brackets is fixedly installed on the top of the work frame. A set of projectors is snapped onto the brackets. A set of limiting grooves is opened on the side of the projectors. A set of limiting blocks is slidably installed on the side of the brackets. The limiting blocks on the side of the brackets are inserted into the limiting grooves on the side of the projectors. Two sets of movable frames are also threaded onto the work frame. A set of movable blocks is threaded onto the top two ends of the movable frames. Two sets of fixing plates are threaded onto the outer ends of the movable blocks.

[0006] In at least some embodiments, a set of first double-ended screws is rotatably mounted on the top of the work frame, and a first screw hole is opened at the bottom of the movable frame. The first screw holes at the bottom of the two sets of movable frames are respectively threaded onto the two ends of the first double-ended screws on the top of the work frame.

[0007] In at least some embodiments, a set of third double-ended screws is rotatably mounted on the outer end of the movable block, and a set of threaded holes is opened on the inner end of the fixing plate, and the threaded holes on the inner ends of the two sets of fixing plates are respectively threaded onto the two ends of the third double-ended screws.

[0008] In at least some embodiments, a set of support plates are fixedly installed on the outer end of the work frame, and a set of sliding holes are provided on the support plates. A set of support rods are fixedly installed on the outer end of the limiting block, and the support rods at the outer end of the limiting block are slidably installed on the sliding holes of the support plates.

[0009] In at least some embodiments, a set of second double-ended screws is rotatably mounted on the top of the movable frame, and a set of second screw holes is opened at the bottom of the movable block, and the two sets of second screw holes at the bottom of the movable block are respectively threaded onto the two ends of the second double-ended screws.

[0010] In at least some embodiments, a set of elastic elements is also sleeved on the support rod at the outer end of the limiting block, and the outer end of the elastic elements is in contact with the inner end face of the support plate on the work frame.

[0011] In at least some embodiments, a set of positioning slots is provided on the top of the bracket, and a set of positioning blocks are fixedly installed on the bottom of the projector, with the positioning blocks at the bottom of the projector snapped into the positioning slots on the top of the bracket.

[0012] Compared with the prior art, the pattern sewing projection-assisted alignment device of this utility model has the following beneficial effects: The projector, in conjunction with the limiting block, allows for easy sliding installation of the limiting block onto the sliding hole in the support plate via the support rod at the outer end of the limiting block. Pulling the limiting block outward engages the positioning block at the bottom of the projector with the positioning groove at the top of the bracket. Once the projector has moved to a fixed position, releasing the limiting block allows it to move inward under the action of the elastic element on the support rod. The limiting block at the side end of the bracket then inserts into the limiting groove at the side end of the projector. This facilitates quick and easy disassembly and assembly of the projector for maintenance, improving the maintenance efficiency of the device.

[0013] The movable frame and movable blocks are designed to be threaded onto both ends of a third double-ended screw via the threaded holes at the inner ends of the two sets of fixed plates. Rotating the third double-ended screw causes the two sets of fixed plates to move inward simultaneously, thus securing the outer end of the seat cover. The first threaded holes at the bottom of the two sets of movable frames are threaded onto both ends of the first double-ended screw at the top of the work frame, and the second threaded holes at the bottom of the two sets of movable blocks are threaded onto both ends of the second double-ended screw. Rotating the first double-ended screw adjusts the distance between the two sets of movable frames, and rotating the second double-ended screw adjusts the distance between the two sets of movable blocks. This provides the device with excellent adjustability, facilitating the securing of seat covers of different sizes as needed. Attached Figure Description

[0021] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples.

[0022] As attached Figure 1 To be continued Figure 6 As shown: Example 1: This utility model provides a pattern sewing projection auxiliary alignment device, including a work frame 1; A set of brackets 101 is fixedly installed on the top of the work frame 1. A set of projectors 2 is snapped onto the brackets 101. A set of limiting grooves 202 is opened on the side end of the projector 2. A set of limiting blocks 104 is slidably installed on the side end of the brackets 101. The limiting blocks 104 on the side end of the brackets 101 are inserted into the limiting grooves 202 on the side end of the projector 2. Two sets of movable frames 3 are also threadedly installed on the work frame 1. A set of movable blocks 4 are threadedly installed at both ends of the top of the movable frames 3. Two sets of fixing plates 403 are threadedly installed on the outer ends of the movable blocks 4.

[0023] like Figure 3 and Figure 4As shown, a set of positioning grooves 102 are provided on the top of the bracket 101, and a set of positioning blocks 201 are fixedly installed on the bottom of the projector 2. The positioning blocks 201 at the bottom of the projector 2 are snapped onto the positioning grooves 102 on the top of the bracket 101. A set of support plates 103 are fixedly installed on the outer end of the work frame 1. A set of sliding holes are provided on the support plates 103. A set of support rods 1041 are fixedly installed on the outer end of the limiting block 104. The support rods 1041 at the outer end of the limiting block 104 are slidably installed on the sliding holes of the support plates 103. A set of elastic elements 1042 are also sleeved on the support rods 1041 at the outer end of the limiting block 104. The outer end of the elastic element 1042 is connected to the support plate on the work frame 1. The inner end faces of 103 are in contact; specifically, the support rod 1041 at the outer end of the limiting block 104 is slidably installed on the sliding hole of the support plate 103. Pulling the limiting block 104 outward will engage the positioning block 201 at the bottom of the projector 2 with the positioning groove 102 at the top of the bracket 101. After the projector 2 moves to the fixed position, the limiting block 104 is released. Under the action of the elastic element 1042 on the support rod 1041, the limiting block 104 moves inward, and the limiting block 104 at the side end of the bracket 101 is inserted into the limiting groove 202 at the side end of the projector 2. This makes it easy and quick to disassemble and assemble the projector 2 of this device for maintenance, thus improving the maintenance efficiency of the device.

[0024] Example 2: Based on Example 1, as follows Figure 5 and Figure 6As shown, a set of first double-ended screws 105 are rotatably mounted on the top of the work frame 1. A first screw hole 301 is opened at the bottom of the movable frame 3. The two sets of first screw holes 301 at the bottom of the movable frame 3 are respectively threaded onto the two ends of the first double-ended screws 105 at the top of the work frame 1. A set of second double-ended screws 302 are rotatably mounted on the top of the movable frame 3.

A set of third double-ended screws 402 is rotatably mounted on the outer end of the movable block 4. A set of threaded holes is opened at the inner end of the fixing plate 403, and the two sets of threaded holes at the inner end of the fixing plate 403 are respectively threaded onto the two ends of the third double-ended screws 402. Specific functions... The threaded holes at the inner ends of the two sets of fixing plates 403 are respectively threaded onto the two ends of the third double-ended screw 402. Rotating the third double-ended screw 402 causes the two sets of fixing plates 403 to move inward simultaneously, so as to fix the outer end of the seat cover. The first screw holes 301 at the bottom of the two sets of moving frames 3 are respectively threaded onto the two ends of the first double-ended screw 105 at the top of the working frame 1. The second screw holes 401 at the bottom of the two sets of moving blocks 4 are respectively threaded onto the two ends of the second double-ended screw 302. That is, rotating the first double-ended screw 105 can adjust the distance between the two sets of moving frames 3, and rotating the second double-ended screw 302 can adjust the distance between the two sets of moving blocks 4, so that the device has better adjustability and can easily fix seat covers of different sizes as needed.

[0025] The specific usage and function of this embodiment are as follows: In use, the limiting block 104 is pulled outward to engage the positioning block 201 at the bottom of the projector 2 with the positioning groove 102 at the top of the bracket 101. After the projector 2 moves to the fixed position, the limiting block 104 is released. Under the action of the elastic element 1042 on the support rod 1041, the limiting block 104 moves inward, and the limiting block 104 at the side end of the bracket 101 is inserted into the limiting groove 202 at the side end of the projector 2. This allows the projector 2 of this device to be easily and quickly disassembled and assembled for maintenance, improving the maintenance efficiency of the device. The threaded holes at the inner ends of the two sets of fixing plates 403 are respectively threaded onto the two ends of the third double-ended screw 402. The third double-ended screw 402 is moved so that the two sets of fixing plates 403 move inward simultaneously to fix the outer end of the seat cover. The first screw holes 301 at the bottom of the two sets of moving frames 3 are respectively threaded to the two ends of the first double-ended screw 105 at the top of the working frame 1. The second screw holes 401 at the bottom of the two sets of moving blocks 4 are respectively threaded to the two ends of the second double-ended screw 302. That is, rotating the first double-ended screw 105 can adjust the distance between the two sets of moving frames 3, and rotating the second double-ended screw 302 can adjust the distance between the two sets of moving blocks 4, so that the device has better adjustability and can be used to fix seat covers of different sizes as needed.
