Detailed Implementation

[0041] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0042] The core of this application is to provide a quick-release connection structure that eliminates the need for fixing holes, effectively ensuring the cleanliness of the power control cabinet. Another core aspect of this application is to provide a power control cabinet incorporating the aforementioned quick-release connection structure that eliminates the need for fixing holes.

[0043] This application provides a quick-release connection structure without fixing holes for fixing the part to be installed 2 to the support 1. The support 1 has a mounting through hole for inserting the part to be installed 2, and includes the part to be installed 2, a number of brackets 3 and a number of threaded fasteners 4.

[0044] The peripheral surface of the to-be-installed piece 2 has a plurality of positioning grooves 21, the first end of the to-be-installed piece 2 has a rim structure 22, and the tail end structure of the to-be-installed piece 2 is used for being inserted into the installation through hole, so that the positioning grooves 21 are located on the back surface side of the support piece 1, and the rim structure 22 is used for abutting against the front surface of the support piece 1.

[0045] The first end of the bracket 3 is used for being inserted into the positioning groove 21, and the second end has a positioning through hole 311;

[0046] A plurality of threaded fasteners 4 are used for being inserted into the corresponding positioning through hole 311 and being inserted into the back surface structure of the support piece 1, and the plurality of threaded fasteners 4 can fix the to-be-installed piece 2 to the support piece 1.

[0047] As shown in Figure 6 and Figure 8 , the rim structure 22 is left on the front surface side of the to-be-installed piece 2, as shown in Figure 7 and Figure 9 , a plurality of positioning grooves 21 are opened on the peripheral surface of the to-be-installed piece 2, and the positioning grooves 21 can adopt rectangular grooves or trapezoidal grooves.

[0048] In order to install the to-be-installed piece 2, the support piece 1 is provided with a through hole along the thickness direction thereof as an installation through hole, which can be a rectangular hole or a circular hole, etc., for inserting the tail end structure of the to-be-installed piece 2 from the front surface side of the support piece 1 to the back surface side thereof, and, as shown in Figures 1 to 5 , after the to-be-installed piece 2 is inserted into place on the support piece 1, the above-mentioned rim structure 22 abuts against the front surface of the support piece 1, and the above-mentioned positioning grooves 21 are located on the back surface side of the support piece 1.

[0049] In cooperation, the connecting structure is also provided with a bracket 3, so as to fix the to-be-installed piece 2 on the support piece 1 through the bracket 3. Specifically, the bracket 3 is placed on the back surface side of the support piece 1, one end of the bracket 3 which is not provided with a positioning through hole 311 is inserted into the positioning groove 21, the positioning through hole 311 of the other end is inserted with a threaded fastener 4, and the head end of the threaded fastener 4 is inserted into the structure on the back surface side of the support piece 1, so as to fix the to-be-installed piece 2 on the support piece 1. Since the bracket 3 and the threaded fastener 4 used for fixing the to-be-installed piece 2 are both located on the back surface side of the support piece 1, it can effectively avoid the dirt that may be generated due to exposure. Since the rim structure 22 is only used for positioning the to-be-installed piece 2, it is not necessary to open a through hole thereon and insert a fastener thereinto to achieve installation, the width of the rim structure 22 can be smaller than the width of the rim structure 22 of the to-be-installed piece 2 in the related art which needs to insert a fastener thereinto to achieve installation, so that the to-be-installed piece 2 does not occupy a large space on the front surface of the support piece 1, that is, the space occupied by the to-be-installed piece 2 on the front surface of the support piece 1 is effectively reduced.

[0050] In some specific embodiments, the first end of the bracket 3 is inserted into the positioning slot 21 in an interference fit, the threaded fastener 4 is inserted into the positioning through hole 311 in a clearance fit, and the threaded fastener 4 is screwed to the support 1.

[0051] On the basis of the above-mentioned embodiments, the positioning through hole 311 is a threaded through hole, and the first end of the bracket 3 is movably inserted into the positioning slot 21.

[0052] Specifically, as shown in Figure 10 and Figure 12 , in use, the head end of the threaded fastener 4 is first inserted into the bracket 3, the end of the bracket 3 without the positioning through hole 311 is inserted into the positioning slot 21, the threaded fastener 4 is continuously screwed until the threaded fastener 4 abuts against the back surface of the support 1, then the threaded fastener 4 is continuously screwed, the bracket 3 continuously abuts against the groove wall of the fixing groove of the to-be-installed piece 2 to drive the to-be-installed piece 2 to tightly fit the edge structure 22 of the to-be-installed piece 2 to the front surface of the support 1, so as to complete the fixing of the to-be-installed piece 2; conversely, when the to-be-installed piece 2 needs to be disassembled, the threaded fastener 4 is screwed in the opposite direction, the threaded fastener 4 is separated from the support 1, the bracket 3 is taken out of the fixing groove of the to-be-installed piece 2, after the threaded fastener and the bracket 3 are disassembled, the pressing force of the to-be-installed piece 2 disappears, the to-be-installed piece 2 can be quickly taken off from the support 1, the disassembly is completed, and thus the convenience of disassembly and assembly of the to-be-installed piece 2 is further reduced.

[0053] Further, the threads on the peripheral wall of the positioning through hole 311 are in a clockwise spiral, and in use, the operator rotates to the right side of himself to tighten to complete the fixing of the to-be-installed piece 2, conversely, the operator rotates to the left side of himself to loosen to complete the disassembly of the to-be-installed piece 2, and thus the operation mistake is avoided.

[0054] On the basis of the above-mentioned embodiments, the bracket 3 has a first positioning plate 31, a second positioning plate 32, and a connecting plate 33.

[0055] The first positioning plate 31, the connecting plate 33, and the second positioning plate 32 are sequentially spliced to form a zigzag plate body structure, and the first positioning plate 31 has the positioning through hole 311, and the second positioning plate 32 is movably inserted into the positioning slot 21.

[0056] Specifically, as shown in Figure 10 and Figure 11 , in use, the head end of the threaded fastener 4 is first inserted into the bracket 3, the end of the bracket 3 without the positioning through hole 311 is inserted into the positioning slot 21, the threaded fastener 4 is continuously screwed until the threaded fastener 4 abuts against the back surface of the support 1, then the threaded fastener 4 is continuously screwed, the bracket 3 continuously abuts against the groove wall of the fixing groove of the to-be-installed piece 2 to drive the to-be-installed piece 2 to tightly fit the edge structure 22 of the to-be-installed piece 2 to the front surface of the support 1, so as to complete the fixing of the to-be-installed piece 2; conversely, when the to-be-installed piece 2 needs to be disassembled, the threaded fastener 4 is screwed in the opposite direction, the threaded fastener 4 is separated from the support 1, the bracket 3 is taken out of the fixing groove of the to-be-installed piece 2, after the threaded fastener and the bracket 3 are disassembled, the pressing force of the to-be-installed piece 2 disappears, the to-be-installed piece 2 can be quickly taken off from the support 1, the disassembly is completed, and thus the convenience of disassembly and assembly of the to-be-installed piece 2 is further reduced.As shown, the first positioning plate 31, the second positioning plate 32, and the connecting plate 33 are all flat plates. A positioning through hole 311 is opened on the first positioning plate 31 along its own thickness direction for inserting threaded fasteners 4. The first positioning plate 31, the connecting plate 33, and the second positioning plate 32 are sequentially spliced ​​to form a zigzag plate structure. The free end of the second positioning plate 32 away from the first positioning plate 31 can be easily inserted into the positioning groove 21. With this setting, the bracket 3 is lighter in weight.

[0057] Based on the above embodiments, the first positioning plate 31 is perpendicular to the connecting plate 33; as shown above. Figure 11 As shown, the included angle A between the first positioning plate 31 and the connecting plate 33 is 90 degrees. This setting helps to apply a greater fastening force to the part to be installed 2 and improve the connection strength between the part to be installed 2 and the support 1.

[0058] like Figure 11 As shown, based on the above embodiment, the included angle B between the second positioning plate 32 and the connecting plate 33 is equal to 70 degrees. This setting helps to reduce the installation difficulty of the bracket 3 and ensure the connection strength between the component to be installed 2 and the support component 1.

[0059] Based on the above embodiment, the positioning groove 21 has a 70-degree angle with the thickness direction of the component 2 to be installed, and the positioning groove 21 is inclined toward the back side of the component 2 to be installed.

[0060] Specifically, such as Figure 1 and Figure 4 As shown, after the component to be installed 2 and the support component 1 are connected by the threaded fastener 4, the threaded fastener 4 extends along the depth direction of the mounting through hole and is perpendicular to the first positioning plate 31. Then the first positioning plate 31 extends along the direction perpendicular to the thickness direction of the component to be installed 2. The structure of this connection is simple and the manufacturing difficulty is low.

[0061] Preferably, in some specific embodiments, the support member 1 is a flat plate structure, the threaded fastener 4 is perpendicular to the support member 1, and the first positioning plate 31 is parallel to the support member 1.

[0062] Based on the above embodiments, the bracket 3 is a bent sheet metal structural component. The bracket 3 has a simple structure, is relatively easy to manufacture, and is conducive to improving the connection strength between the component to be installed 2 and the support component 1.

[0063] And, the length L1 of the first positioning plate 31 is greater than the length L2 of the second positioning plate 32, and the length L2 of the second positioning plate 32 is greater than the length L3 of the connecting plate 33, for example, in some embodiments, the length L1 of the positioning plate 31 is equal to 13mm, the length L2 of the second positioning plate 32 is equal to 6.6mm, and the length L3 of the connecting plate 33 is equal to 5.6mm. In this way, the stress on the to-be-installed piece 2 is effectively increased, and the threaded fastener is facilitated to be installed.

[0064] As shown in Figure 10 the above embodiments, the side of the second positioning plate 32 away from the first positioning plate 31 has a first fillet structure 321 to reduce the difficulty of inserting the bracket 3 into the positioning groove 21.

[0065] As shown in Figure 10 the above embodiments, the top corner of the first positioning plate 31 away from the second positioning plate 32 has a second fillet structure 312 to avoid injury to the operator.

[0066] On the basis of the above embodiments, the to-be-installed piece 2 is of a rectangular structure, and the peripheral surface of the to-be-installed piece 2 has eight positioning grooves 21, and each side of the to-be-installed piece 2 has two positioning grooves 21.

[0067] The number of brackets 3 is eight, and the first ends of the eight brackets 3 are movably inserted into the corresponding positioning grooves 21.

[0068] Specifically, as shown in Figure 3 and Figure 5 eight positioning grooves 21 are formed around the center of the to-be-installed piece 2, of which two positioning grooves 21 are formed at intervals on the upper side of the to-be-installed piece 2, another two positioning grooves 21 are formed at intervals on the lower side of the to-be-installed piece 2, and the remaining two positioning grooves 21 are formed at intervals on the right side of the to-be-installed piece 2. In cooperation, the eight brackets 3 are inserted into the eight positioning grooves 21 one by one, and the threaded fasteners 4 are respectively inserted into the free ends of the eight brackets 3.

[0069] In addition to the above fixing-hole-free quick disassembly and assembly type connecting structure, the application also provides a power control cabinet comprising the fixing-hole-free quick disassembly and assembly type connecting structure disclosed in the above embodiments. The cabinet body is provided as the panel of the cabinet body, so that the to-be-installed piece 2 can be fixed at a predetermined position of the panel. In some embodiments, the to-be-installed piece 2 refers to a display. Since the fixing-hole-free quick disassembly and assembly type connecting structure disclosed in the above embodiments is adopted, the display provided in the power control cabinet can be kept clean, and the display is also increased in aesthetic appearance.
