More importantly, once the welding position needs maintenance, the entire welding position is difficult to repair locally, and often needs to be replaced or welded after cutting, which is extremely difficult to maintain in the later period. In addition, the bolt or nut connection adopts threaded fasteners to realize the detachable connection of the pole frame. The advantage of this mode is convenient installation and maintenance, but in actual application, it is necessary to predrill or tap on the pole frame, which undoubtedly increases the processing cost. Moreover, under the action of long-term vibration or external force, the bolt or nut is prone to loosening, which needs to be checked and tightened regularly, otherwise it will affect the stability of the pole frame connection.

[0031] The embodiments of the present utility model will be described in detail below, examples of which are shown in the drawings, wherein the same or similar numerals represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present utility model, and cannot be understood as a limitation of the present utility model.

If it is described to the first, the second is only used for distinguishing the purpose of technical features, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of indicated technical features or implicitly indicating the sequence of indicated technical features.

[0034] In the description of the utility model, unless otherwise explicitly limited, the words such as setting, installation, connection, etc. Should be understood in a broad sense, and the person skilled in the art can reasonably determine the specific meaning of the above words in the utility model according to the specific content of the technical scheme.

[0035] In the description of the utility model, the description of the reference terms "one embodiment", "some embodiments", "illustrative embodiment", "example", "specific example" or "some examples" means that the specific features, structures, materials or characteristics described in combination with the embodiment or example are included in at least one embodiment or example of the utility model. In the specification, the illustrative description of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0036] The existing rod frame butt joint mode mainly includes welding connection, bolt or nut connection and the like. Among them, the welding process is complex, professional equipment must be used and operated by technical personnel. Moreover, in the welding process, the welding position is easy to deform due to thermal stress, which affects the overall structural precision of the rod frame, and more importantly, once the welding position needs maintenance, the entire welding position is difficult to repair locally, and often needs to be replaced or cut and re-welded, which is extremely difficult to maintain in the later period. In addition, the bolt or nut connection realizes the detachable connection of the rod frame by using threaded fasteners. The advantage of this way is convenient to install and maintain, but in actual application, it is necessary to pre-drill or tap on the rod frame, which undoubtedly increases the processing cost, and under the action of long-term vibration or external force, the bolt or nut is easy to loosen, which needs to be checked and tightened regularly, otherwise it will affect the stability of the rod frame connection. In addition, the connection position is exposed and is easy to be corroded, which further affects the stability of the structure.

[0037] Furthermore, some problems commonly exist in the connection nodes of some modular pole structures. For example, they have poor resistance to loosening. During long-term use, under the influence of vibration, external forces, and other factors, the connection points are prone to gradually loosening, thus affecting the strength and stability of the entire pole structure. Moreover, the installation process is often cumbersome, requiring specialized tools or complex procedures, making rapid assembly difficult and impacting construction efficiency. In particular, when a component in a connection node is damaged, maintenance is challenging, often requiring the destruction of the original connection structure for replacement. This not only increases maintenance costs but also affects the normal use of the pole.

[0038] Therefore, such as Figure 1 As shown, the plug-in type connecting buckle 100 proposed in this utility model includes a first connecting part 110 and a second connecting part 120 integrally connected to the first connecting part 110. The first connecting part 110 is provided with a communicating first positioning groove 1101 and a first engaging groove 1102, and the second connecting part 120 is provided with a communicating second positioning groove 1201 and a second engaging groove 1202. (See also...) Figure 2 The openings of the first positioning groove 1101 and the first snap-fit ​​groove 1102 are both arranged facing downwards. The first positioning groove 1101 is for the first crossbar 211 to be inserted and can drive the first crossbar 211 to snap into the first snap-fit ​​groove 1102. Similarly, the openings of the second positioning groove 1201 and the second snap-fit ​​groove 1202 are both arranged facing downwards. The second positioning groove 1201 is for the second crossbar 221 to be inserted and can drive the second crossbar 221 to snap into the second snap-fit ​​groove 1202. It should be noted that the integrated double-connector design achieves an efficient and stable connection between the first crossbar 211 and the second crossbar 221. For example, adjacent pole frames 320 are connected at the corresponding crossbars by plug-in type connecting buckles 100. The downward-opening positioning groove and the snap-fit ​​groove form a step-by-step guiding and locking mechanism. The positioning and locking of the crossbar can be completed simply by vertical insertion, without the need for additional tools. This significantly reduces the assembly difficulty, improves the assembly efficiency, and facilitates the maintenance of the pole frames 320 corresponding to the first crossbar 211 and the second crossbar 221 after disassembly.

[0039] Refer to Figure 1 and Figure 2In some embodiments of the utility model, the width of first positioning slot 1101 matches the outer diameter of first horizontal rod 211, which can ensure that first horizontal rod 211 forms a close fit after being inserted into first positioning slot 1101, avoids shaking or deviation caused by gaps, and thus can be better clamped into first clamping slot 1102, further improves the structural stability and anti-loosening performance of the connection node, and at the same time reduces the abnormal noise or wear problems caused by vibration or external force in long-term use. Similarly, the width of second positioning slot 1201 matches the outer diameter of second horizontal rod 221, which can ensure that second horizontal rod 221 forms a close fit after being inserted into second positioning slot 1201, avoids shaking or deviation caused by gaps, and thus can be better clamped into second clamping slot 1202, and at the same time, the structural stability and anti-loosening performance of the connection node can be improved, and the abnormal noise or wear problems caused by vibration or external force in long-term use can be reduced.

[0040] Referring again to Figure 2 Taking combination rack 200 as an example, in some embodiments of the utility model, combination rack 200 includes first rod rack 210 and second rod rack 220, wherein first rod rack 210 is provided with first horizontal rod 211 and first vertical rod 212, and second rod rack 220 is provided with second horizontal rod 221 and second vertical rod 222. In this regard, first positioning slot 1101 can allow first vertical rod 212 connected to the end of first horizontal rod 211 to enter and position first vertical rod 212, and similarly, second positioning slot 1201 can allow second vertical rod 222 connected to the end of second horizontal rod 221 to enter and position second vertical rod 222. Through the positioning function of first positioning slot 1101 and second positioning slot 1201 on first vertical rod 212 and second vertical rod 222 respectively, rod rack 320 is further constrained in multiple directions through vertical rods on the basis of horizontal rod connection, which enhances the anti-overturning ability and load stability of the overall structure, is especially suitable for scenes that need to bear external force or vibration, and at the same time simplifies the installation steps and can complete multi-dimensional positioning without additional fixing devices.

[0041] Referring again to Figure 1 and Figure 2In some embodiments of the utility model, first clamping groove 1102 and second clamping groove 1202 are arranged at the same horizontal position, which can ensure that first horizontal rod 211 and second horizontal rod 221 are in the same stress plane after insertion, avoid local stress concentration or distortion caused by height difference, thereby improving the stress uniformity of the connection node, prolonging the service life, and reducing the repair difficulty caused by structural deviation during maintenance. Further, first clamping groove 1102 and second clamping groove 1202 are arranged perpendicularly, which are suitable for first rod frame 210 and second rod frame 220 that are butt-jointed at 90°. First horizontal rod 211 and second horizontal rod 221 are locked by plug-in type connecting buckle 100, forming a right-angle locking structure, which significantly improves the shear resistance and torsion resistance, and is especially suitable for combined rod frame 320 structure that needs to bear complex external force, such as lateral thrust or torsion. It is easy to understand that when first rod frame 210 and second rod frame 220 are butt-jointed at other angles, such as 30°, 45°, 70°, 115°, 130°, etc., the intersection angle of first clamping groove 1102 and second clamping groove 1202 can be designed as needed according to the actual situation.

[0042] Referring again to Figure 1 In some embodiments of the utility model, the side of the first connecting part 110 away from the connection with the second connecting part 120 is provided with a first clamping part 111, the first positioning groove 1101 is arranged on the first connecting part 110, and the first clamping groove 1102 is arranged on the first clamping part 111, so that the plug-in paths of the first horizontal rod 211 and the first vertical rod 212 are separated and do not interfere with each other. This not only simplifies the step logic of single plug-in operation, but also can achieve double locking effect through step-by-step clamping, further improve the reliability of the connection, and at the same time, it is convenient to separately disassemble the rod in one direction without damaging the overall structure. For example, in application, the first vertical rod 212 and the first horizontal rod 211 with the same outer diameter are horizontally or vertically transversely moved into the first positioning groove 1101, and then the first clamping part 111 is moved downward to be clamped with the first horizontal rod 211. At this time, the first vertical rod 212 is limited by abutting with the first positioning groove 1101. Similarly, the side of the second connecting part 120 away from the connection with the first connecting part 110 is provided with a second clamping part 121, the second positioning groove 1201 is arranged on the second connecting part 120, and the second clamping groove 1202 is arranged on the second clamping part 121. The application and function of the second clamping part 121 on the second connecting part 120 can refer to the application and function of the first clamping part 111 on the first connecting part 110, which will not be described in detail here.
