Description

Technical Field

[0001] The utility model relates to the technical field of single-groove double-needle needle plates, in particular to a single-groove double-needle needle plate device for a computer host. Background Art

[0002] A single slot double needle needle board is a component used in knitting machines or looms, commonly used in the textile and weaving industries. This needle board has one slot but can accommodate two needles for knitting or weaving operations.

[0003] For example, the Chinese patent with publication number CN215593342U, a plug for a single-slot double-needle needle plate device, includes a plug body, and avoidance grooves for avoiding the expansion ring plate on the discarded needle are opened on the two side walls of the front end of the plug body, and the front end of the avoidance groove is a through groove; the bottom surface of the avoidance groove is divided into two parts: a horizontal surface and an inclined surface, the front end of the horizontal surface is flush with the front end surface of the plug body, the rear end of the horizontal surface is connected to the lower end of the inclined surface, and the high end of the inclined surface is flush with the side wall surface of the plug body.

[0004] In the above scheme, avoidance grooves for avoiding the expansion piece on the needle are opened on the wall surfaces on both sides of the front end of the insert body, and the front end of the avoidance groove is a through groove; the bottom surface of the avoidance groove is divided into two parts: a horizontal surface and an inclined surface. The inclined surface allows the needle to remain stable during the retreat process and will not collide with the expansion piece. However, during the retreat process of the expansion piece on the needle, the expansion piece contacts the inclined surface and retreats tiltedly, resulting in the following disadvantages: during the retreat process of the expansion piece on the needle, the side surface of the expansion piece contacts the inclined surface and retreats tiltedly. In the long-term production process, multiple contacts between the side surface of the expansion piece and the inclined surface can easily cause the needle and the expansion piece to be skewed, thereby causing damage to the needle and the expansion piece, thereby reducing the product yield. For this reason, we propose a single-slot double-needle needle plate device for a computer host. Utility Model Content

[0005] The purpose of the utility model is to provide a single-slot double-needle needle plate device for a computer host, so as to solve the problem that during a long-term production process, the side of the expansion plate contacts the inclined surface many times, which easily causes the needle and the expansion plate to be skewed, thereby causing damage to the needle and the expansion plate.

[0006] In order to achieve the above-mentioned purpose of the utility model, the utility model adopts the following technical scheme: a single-slot double-needle needle plate device for a computer host, including a needle plate, a top surface of the needle plate is provided with a plurality of insertion slots, the interiors of the plurality of insertion slots are removably inserted with insertion bodies, both sides of the plurality of insertion bodies are provided with stabilizing slots, one side of the inner wall surface of the stabilizing slot is provided with a slow-retreat slot, the upper and lower sides of the inner wall of the slow-retreat slot are respectively provided with concave arc slopes, and the two concave arc slopes are semi-conical at one end away from the opening of the slow-retreat slot.

[0007] Preferably, a plurality of positioning holes are opened on one side of the insert body, positioning rods are arranged inside the positioning holes, and the positioning holes and the positioning rods are interference fit.

[0008] Preferably, two fixing holes are provided on one side of the insert body, a fixing rod is inserted into the fixing hole, a clamping groove is provided on the top surface of the needle plate, the clamping groove is connected with the insert groove, and the clamping groove and the fixing rod are detachably clamped.

[0009] Preferably, two protective plates are fixed to the top surface of the needle plate, and the two protective plates are respectively located on both sides of the insert body, and a number of mounting holes are opened on the adjacent sides of the two protective plates, and the several mounting holes are respectively inserted into the two ends of a number of positioning rods.

[0010] Preferably, a plurality of limit baffles are vertically arranged between the two protective plates, a plurality of positioning notches are opened on the top surface of the insert body, and the plurality of positioning notches are arranged along the direction of the limit baffles. The limit baffles are slidably inserted into the positioning notches, and the two ends of the limit baffles are respectively abutted against the two sides of the protective plates close to each other.

[0011] Preferably, a plurality of threaded holes are formed on the top surface of the needle plate, and bolts are connected to the internal threads of the threaded holes.

[0012] Compared with the prior art, a single-slot double-needle needle plate device for a computer host using the above technical solution has the following beneficial effects:

[0013] 1. In use, when the needle is retreating, the expanding ring piece of the needle enters the slow retreat groove. The inclined design of the top and bottom surfaces of the slow retreat groove will fit the shape of the expanding ring piece, and the top and bottom surfaces of the expanding ring piece are limited and buffered, so that when the needle is retreating, the expanding ring piece will not collide with each other under the fit of the two surfaces. In addition, by limiting and slowly retreating the top and bottom surfaces of the expanding ring piece, the needle and the expanding ring piece will not be skewed or damaged during long-term use, thereby extending the service life of the needle and the expanding ring piece, thereby improving the product yield rate;

[0014] 2. During use, the staff can make the insert body more firmly in the insert slot by inserting the fixing hole and the fixing rod, and the snap-in slot and the fixing rod can be detachably snap-in, which is convenient for disassembly and maintenance;

[0015] 3. During use, the two ends of the positioning rod are abutted by two protective plates. The interference fit between the positioning rod and the positioning hole on the insert body can prevent the insert body from shifting in the insert slot, making the insert body more stable. The limit stopper and the positioning notch on the insert body are slidably inserted, and the limit stopper is abutted between the two protective plates. In this way, the limit stopper can further prevent the insert body from shifting in the insert slot, thereby improving the accuracy of production. The threaded connection between the threaded hole and the bolt can facilitate the installation of the needle plate in the specified position and facilitate disassembly and maintenance.
