[0025] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0026] In the description of this utility model, it should be understood that the terms "upper," "lower," "left," "right," "vertical," "horizontal," etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and 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, and therefore should not be construed as a limitation of this utility model. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0027] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0028] The following is for reference. Figures 1-4 Describe this utility model;

[0029] Rectifier bridge anti-reverse fixture, including:

[0030] The support frame 100 includes vertically arranged support legs 110 and obliquely arranged sliding plates 120; the support legs 110 and the sliding plates 120 are fixedly connected.

[0031] The guide seat 200 is detachably and fixedly mounted on the sliding plate 120. It has several tube insertion slots 210 with top openings. The tube insertion slots 210 are adapted to the packaging tubes, and the packaging tubes are inserted into the tube slots 210. The bottom of the tube insertion slots 210 is provided with a discharge slot 220 that communicates with it. The cross-section of the discharge slot 220 is V-shaped, that is, larger at the top and smaller at the bottom. The discharge slot 220 is provided with a support platform 230 adapted to the rectifier bridge encapsulation body. The rectifier bridge is not a symmetrical design. The support platform 230 can better fix the positive electrode in the same direction and at the same time improve the convenience of picking up.

[0032] The packaging tube filled with rectifier bridges is inserted into the insertion slot 210. The width of the slot is set so that the outlet of the packaging tube is positioned at the junction of the insertion slot 210 and the outlet slot 220. The first rectifier bridge at the outlet slides into the outlet slot (with the plastic seal on top and the four pins on the bottom). The second rectifier bridge is mostly located inside the packaging tube. That is, the length of the outlet slot 220 is less than the sum of the lengths of the two rectifier bridges. This prevents friction during material handling and avoids carrying the previous material out of the track, ensuring that only one material can be picked up at a time.

[0033] When the rectifier bridges leave the factory, the factory will install several rectifier bridges in the same direction in sequence into a customized packaging tube (the packaging tube has a storage cavity, with hollowed-out ends, and is covered by a detachable and fixedly connected cap; the cross-sectional structure of the storage cavity is adapted to the side structure of the rectifier bridge) so that the positive and negative directions of the rectifier bridges in the whole tube are consistent.

[0034] In this case, the center line of the discharge trough 220 is not on the same straight line as the insertion trough 210, but slightly off to one side of the insertion trough 210. This results in a certain misalignment between the rectifier bridge of the discharge trough 220 and the previous rectifier bridge, reducing friction between materials and preventing damage to the materials.

[0035] The top surface of the support platform 230 is located below the top surface of the guide seat 200.

[0036] The bottom of the support leg 110 is equipped with an adjustable and fixed height-increasing leg 300.

[0037] The outrigger 110 is provided with at least one pair of positioning holes;

[0038] The heightening leg 300 is provided with several positioning holes 2 evenly distributed vertically; the number of horizontal positioning holes 2 of the heightening leg 300 is equal to the number of horizontal positioning holes 2 of the support leg 110, and they correspond one to one. By adjusting the vertical positioning holes 2 of the heightening leg 300, the inclination of the sliding plate 120 can be adjusted for adaptation.

[0039] Positioning hole one and positioning hole two are connected and fixed by positioning pins.

[0040] The top opening of the insertion slot 210 has a rounded chamfer to facilitate the insertion of the corresponding packaging tube.

[0041] The guide seat 200 has several hollowed-out sections to reduce the load on the support frame 100.

[0043] (1) The accompanying drawings of the embodiments disclosed in this case only involve the structures involved in the embodiments disclosed in this case. Other structures can refer to the general design.

[0044] (2) Where there is no conflict, the embodiments and features disclosed in this case can be combined with each other to obtain new embodiments;
