[0016] In order to more clearly illustrate the purpose, technical solutions and advantages of the embodiments of the present invention, the present invention will be further described below in conjunction with the accompanying drawings and embodiments for a clear and complete description. Obviously, the embodiments described are partial embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. In addition, the directional terms mentioned in the present invention, such as "up", "down", "front", "back", "left", "right", "inside", "outside", etc., are only references to the directions of the attached diagrams. The directional terms used are for better and clearer explanation and understanding of the present invention, rather than indicating or implying the orientation that the present invention must have, and therefore cannot be understood as limitations on the present invention.

[0017] The present invention is implemented as follows Figure 1 and Figure 2As shown in, a positioning pin comprises a positioning pin cover 1 and a positioning pin rod 2 fixedly connected to the positioning pin cover 1. The positioning pin cover 1 can be in different shapes such as round, oval, square, etc. according to different usage requirements, or it can be a cross bar perpendicular to the positioning pin rod 2, and the positioning pin rod 2 is fixedly connected thereto. The two are made of iron material, and can be made separately and then welded together, or the two are formed as one piece to reduce the process and facilitate production. Preferably, the two are formed as one piece. The positioning pin rod 2 selects a cylindrical structure, such as a cylinder or a square cylinder, to reduce resistance in the process of puncturing the component to be positioned. A plurality of pin rod slots 21 in the axial direction are arranged on the outer wall of the positioning pin rod 2 at intervals along its circumference, that is, the pin rod slots 21 are on the positioning pin rod 2. The locating pin 2 is arranged at intervals in the circumferential direction, preferably at equal intervals, and the direction of the pin rod slot 21 is the same as the axial direction of the positioning pin rod 2. In this way, after the positioning pin passes through the component to be positioned, the positioning pin rod 2 and the component to be positioned form a large contact area, thereby increasing the friction between each other and avoiding loosening. The pin rod slot 21 is a V-shaped slot, and the groove walls of adjacent slots are inverted V-shaped. Multiple pin rod slots form a serrated structure. The positioning pin rod 2 is provided with a positioning pin head 3 with a conical structure integrally formed with the positioning pin rod 2 at one end away from the positioning pin cover 1. The positioning pin head 3 and the positioning pin cover 1 are at opposite ends of the positioning pin rod 2. The positioning pin head 3 is a conical structure, and its length is not more than 2 cm. The positioning pin head 3 is 15-20 degrees to the axis of the positioning pin rod 2. The cone angle, such length and angle can make it easier to puncture the positioning component, and it will not be deformed during the puncture process. At the same time, it can be bent well after passing through the component to be positioned, ensuring its contact area with the surface of the component to be positioned, thereby avoiding loosening. The middle of the positioning pin head 3 is hollowed out with a pin head through hole 32 with a conical structure, that is, the bottom end of the pin head through hole 32 is at the end of the positioning pin rod 2, and the top of the pin head through hole 32 corresponds to the top of the positioning pin head 3. The pin head through hole 32 divides the positioning pin head 3 into a left pin head 30 and a right pin head 31 that are detachably connected at the top of the vertebral body. The left pin head 30 and the right pin head 31 can be bent relative to the positioning pin rod 2, so that the interior of the positioning pin head 3 forms a hollow structure. When not in use, the left and right pin heads are connected together, so that When in use, first pass the positioning pin head 3 through the component to be positioned, then separate the left and right pin heads and bend them to press against the surface of the component to be positioned, thereby completing the positioning. The separation of the left and right pin heads can be achieved by using a plug. The width of the bottom surface of the plug is greater than the diameter of the pin head through hole 32. First, insert the plug into the pin head through hole 32, and then rotate the plug so that the edge of the side where the plug is larger than the diameter of the pin head through hole 32 presses against the inner walls of the left and right pin heads, and then move the plug toward the top of the pin head through hole 32. The left and right pin heads are pushed outward to separate and bend relative to the positioning pin rod 2. The connection of the left and right pin heads can be connected at the position near the top by a corresponding card block or card groove, or by forming a breakable crease at the top by the stamping groove after stamping.Or the two can be connected by putting a conical sleeve on the top of the pin. In this way, the bent left and right pin heads press against different positions on the surface of the component to be positioned, forming multiple fixed points. The positioning structure is firm and will not loosen, ensuring the positioning effect.

[0018] Further improvements, such as Figure 1 and Figure 2 As shown in , the left pin head 30 and the right pin head 31 are both provided with a pin head retaining groove 4 along the radial direction of the positioning pin rod 2 at the connection with the positioning pin rod 2, that is, the pin head retaining groove 4 is provided at the bottom end position corresponding to the pin head through hole 32, which facilitates the bending of the left and right pin heads without affecting the puncture of the left and right pin heads. At this time, according to different usage modes, the pin head retaining groove 4 is provided on the inner surface and / or outer surface of the left pin head 30 and the right pin head 31, that is, the inner surface, outer surface, or inner and outer surfaces of the left pin head 30 are both provided with the pin head retaining groove 4, and the inner surface, outer surface, or inner and outer surfaces of the right pin head 31 are also provided with the pin head retaining groove 4.

[0019] Further improvements, such as Figure 1 and Figure 2 As shown in, the positioning pin rod 2 is provided with a first through hole 20 along its axial direction with a diameter larger than the diameter of the bottom end of the pin head through hole 32, and the positioning pin rod 20 forms a cylindrical structure. Since the diameter of the first through hole 20 is larger than the diameter of the pin head through hole 32, the left and right pin heads corresponding to the bottom ends of the pin head through holes 32 have a portion of their projections in the first through hole 20, that is, the bottom ends of the left and right pin heads are partially blocked at the end of the first through hole 20, and the parts passing through the first through hole 20 will exert force on the left and right pin heads, facilitating the separation of the left and right pin heads. The positioning pin cover 1 is provided with a second through hole 20 which is coaxial with the first through hole 20 and has a diameter not less than that of the first through hole 20. In this way, the left and right pin heads can be separated by inserting a component which passes through the second through hole 10 and the first through hole 20 in sequence into the pin head through hole 32, thereby bending and positioning the left and right pin heads. The component inserted into the two through holes can be a piston rod having a length not less than the sum of the thickness of the positioning pin cover 1, the length of the positioning pin rod 2, and the length of the positioning pin head 3, and the diameter of the piston rod matches the diameter of the first through hole 20. When in use, the piston rod is inserted into the second through hole 10 and the first through hole 20 in sequence, and then the piston rod slides in the first through hole 20 toward the pin head through hole 32. After the piston rod passes through the first through hole 20, it presses against the bottom ends of the left and right pin heads, and then continues to push the piston rod to move toward the top end of the pin head through hole 32 in the pin head through hole 32, so that the left and right pin heads are forced to separate and then bend and position. In order to facilitate the movement of the piston rod in the pin head through hole 32 when the piston rod is pressed against the bottom ends of the left and right pin heads, the left pin head 30 and the right pin head 31 have rounded corners at one end adjacent to the first through hole 20. The rounded corners reduce resistance and facilitate the movement of the piston rod. At the same time, the head of the piston rod is also set to be spherical to facilitate its sliding.

[0020] A method for applying a positioning pin, using the positioning pin as described above, the steps are as follows:

[0021] S1, the filling material is sealed in the packaging bag to form a geometric filling piece with the packaging bag. For example, expanded perlite particles and rock wool used in thermal insulation wall panels can be used as filling materials. The packaging bag can be made of an accordion bag. After the filling material is filled in the packaging bag, vacuum is applied to make the two materials adhere to each other to form a geometric filling piece, which is convenient for placement in the box;

[0022] S2, place the filling pieces in the box and seal the box. The box is made of cardboard, which is convenient, practical and environmentally friendly;

[0023] S3, insert the positioning pin into the box from the top of the box and make the positioning pin head 3 pass through the bottom surface of the box, then use the pin head through hole 32 to separate the left and right pin heads, and bend the positioning pin head 3 outward and press it against the bottom surface of the box, so as to fix the filling piece in the box and prevent it from sliding in the box.

[0024] It should be understood that those skilled in the art may make improvements or changes based on the above description, and all such improvements and changes should fall within the scope of protection of the appended claims of the present invention.
