Description

Technical Field

[0001] The utility model relates to the technical field of steel connectors and discloses a double-fixed steel connector. Background Art

[0002] Connectors are devices or parts used to connect two or more components or structures. They play a vital role in industries such as industry, construction, and machinery manufacturing, ensuring the integrity and stability of structures. Connectors come in a variety of types and forms, depending on the application and needs.

[0003] Steel connectors are typically used to fasten two or more steel components together. They are crucial in construction and engineering, ensuring structural stability and safety. However, in practice, most steel connectors are secured using threaded fastening methods such as bolts, nuts, and screws. This single method of fastening can lead to loosening of the steel components if the nut becomes loose for some reason.

[0004] Therefore, a steel connection piece that can be doubly fixed is needed. Utility Model Content

[0005] In order to overcome the disadvantages of the prior art that, in actual use, most steel connectors are fixed by means of bolts, nuts, screws, etc. through threaded fastening. Since it relies on only a single fixing method, if the nut loosens for some reason, the steel may also become loose. The purpose of the utility model is to provide a steel connector that can be doubly fixed.

[0006] The utility model provides the following technical solution: a steel connector that can be doubly fixed, including a connector body, bolts and nuts, a plurality of bolts are provided on the connector body, and the plurality of bolts are all threadedly provided with nuts, two bonding grooves are provided on the connector body, and a liquid inlet is provided on the connector body.

[0007] As a further preferred solution, it also includes a steel plate connector, a tenon block, a tenon rod and a connecting plate. Two tenon blocks are slidingly arranged on the connector body. A plurality of tenon rods are fixedly connected to the connector body. The tenon blocks are clamped with the tenon rods. A steel plate connector is fixedly connected to the side of the tenon block away from the connector body. Connecting plates are detachably arranged on both sides of the steel plate connector.

[0008] As a further preferred solution, mounting holes matching the bolts are provided on the connecting plate.

[0009] As a further preferred solution, it also includes a stabilizing rod, a rotating plate, a spiral spring, a limit plate and a fitting block. Both the connector body and the steel plate connector are slidably provided with two stabilizing rods, and rotating plates are rotatably provided on both sides of the stabilizing rod. A spiral spring is sleeved on the rotating plate, and both ends of the spiral spring are connected to the rotating plate. The bottom of the stabilizing rod is fixedly connected to the limit plate, and both the connector body and the steel plate connector are slidably provided with two sets of fitting blocks.

[0010] As a further preferred solution, it also includes connecting blocks, pressing plates and anti-slip rings. The connector body and the steel plate connector are fixedly connected to multiple connecting blocks. Pressing plates are slidably provided on the left and right sides of the connector body and the steel plate connector. The pressing plates are docked with the connecting blocks, and multiple anti-slip rings are provided inside the connector body.

[0011] As a further preferred solution, a pull ring is further included, and the pull ring is fixedly connected to the stabilizing rod.

[0012] Compared with the prior art, the present invention provides a steel connector that can be doubly fixed, which has the following beneficial effects: 1. Epoxy resin adhesive is injected into the bonding groove through the liquid inlet on the connector. After the epoxy resin adhesive is dried and solidified, the steel is tightly adhered to the connector body. Even if the nut is loosened for some reason, the steel will not loosen, thereby achieving a double fixation effect.

[0013] 2. By inserting the tenon block into the connector body, the tenon block and the tenon rod are engaged, and then the steel plate connector is connected to the connector body, thereby increasing the number of connectors and facilitating the fixing of multiple pieces of steel.

[0014] 3. When the rotating plate completely enters the steel, the elastic force of the spiral spring will cause the rotating plate to rotate outward and reset, and then pull the stabilizing bar to make the rotating plate contact the steel, thereby limiting the steel and achieving the purpose of temporary fixation.

[0015] 4. The high pressure generated by the press is used to press the pressing plate into the connector body to form a tight fit, so that the connector can be used in different scenarios and improve the efficiency of the connector. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Example 1: A double-fixed steel connector, see Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 7 , including a connector body 1, bolts 2 and nuts 3. The connector body 1 is provided with a plurality of bolts 2, and the plurality of bolts 2 are all threadedly provided with nuts 3. The connector body 1 is provided with two bonding grooves 4, and the connector body 1 is provided with a liquid inlet 5.

[0026] When it is necessary to fix the steel together, first, insert the steel into the corresponding position in the connector body 1, then pass the bolt 2 through the reserved holes on the connector body 1 and the steel, and then tighten the nut 3 on the bolt 2 to preliminarily fix the steel. Then, inject epoxy resin adhesive into the bonding groove 4 through the liquid inlet 5 on the connector. After the epoxy resin adhesive dries and solidifies, the steel is tightly adhered to the connector body 1. In this way, even if the nut 3 loosens for some reason, the steel will not loosen, thereby achieving a double fixation effect.

[0027] Example 2: Based on Example 1, please refer to Figure 1 and Figure 4 Two tenon blocks 7 are slidingly provided on the connector body 1, and four tenon rods 8 are provided on the connector body 1 by welding. The tenon blocks 7 are clamped with the tenon rods 8, and a steel plate connector 6 is provided on the side of the tenon block 7 away from the connector body 1 by welding. Connecting plates 9 are detachably provided on the left and right sides of the steel plate connector 6. Mounting holes matching the bolts 2 are opened on the connecting plate 9. Insert the bolts 2 into the connecting plate 9, and then tighten the nuts 3 to connect the connecting plate 9 and the connector body 1.

[0028] When multiple pieces of steel need to be fixed, first insert the tenon block 7 into the connector body 1 so that the tenon block 7 is engaged with the tenon rod 8, and then connect the steel plate connector 6 to the connector body 1, thereby increasing the number of connectors and facilitating the fixing of multiple pieces of steel. After fixing the steel plate connector 6 on the connector body 1, insert the steel into the steel plate connector 6, and finally fix the multiple pieces of steel with the bolts 2 and nuts 3.

[0029] See also Figure 1 、 Figure 5 and Figure 6 The connecting body 1 and the steel plate connecting piece 6 are both slidably provided with two stabilizing rods 10, and rotating plates 11 are rotatably provided on both sides of the stabilizing rod 10. A spiral spring 12 is sleeved on the rotating plate 11, and both ends of the spiral spring 12 are connected to the rotating plate 11. A limiting plate 13 is provided at the bottom of the stabilizing rod 10 by welding. The connecting body 1 and the steel plate connecting piece 6 are both slidably provided with two sets of fitting blocks 14, and a pull ring 15 is provided on the stabilizing rod 10 by welding. The pull ring 15 increases the fulcrum between the hand and the stabilizing rod 10, which is convenient for pulling the stabilizing rod 10.

[0030] When it is necessary to temporarily fix the steel, first insert the steel into the connector body 1, and then insert the stabilizing rod 10 into the connector body 1. At this time, the connector body 1 will squeeze the rotating plate 11 to rotate inward, and the spiral spring 12 will also deform accordingly. When the rotating plate 11 completely enters the interior of the steel, the elastic force of the spiral spring 12 will cause the rotating plate 11 to rotate outward and reset. Then, pull the stabilizing rod 10 to make the rotating plate 11 contact the steel, thereby limiting the steel and achieving the purpose of temporary fixation. Subsequently, the fitting block 14 is inserted into the connector body 1 to limit the stabilizing rod 10.

[0031] See also Figure 1 and Figure 7 The connector body 1 and the steel plate connector 6 are both provided with eight connecting blocks 16 by welding. The connector body 1 and the steel plate connector 6 are both slidably provided with pressing plates 17 on the left and right sides. The pressing plates 17 are docked with the connecting blocks 16. Three anti-slip rings 18 are provided inside the connector body 1.

[0032] When steel is needed for the manufacture of precision equipment, the steel is first inserted into the connector body 1, and then the pressing plate 17 is put on the connector body 1 or the steel plate connector 6 to dock the pressing plate 17 with the connecting block 16. Next, a press is used to press the pressing plate 17 into the connector body 1 or the steel plate connector 6 through the high pressure generated by the press to form a tight fit, so that the connector can be used in different scenarios, thereby improving the efficiency of the connector.

[0033] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
