The utility model installs the inner concave block and the second mounting plate on the outer side of the second bus duct body by screws, and installs the fixing block and the first mounting plate on the outer side of the first bus duct body by screws. First, align the connection positions of the first bus duct body and the second bus duct body, insert the outer protrusion and the elastic steel sheet into the inner cavity of the inner concave block, and there is a certain gap between the outer protrusion and the elastic steel sheet after the connection, and the gap forms a slot, and the card strip is just stuck in the slot, which plays a role of limiting, and prevents the outer protrusion and the elastic steel sheet from moving in the inner cavity of the inner concave block. The elastic steel sheet is elastic, and the convex part is just stuck in the card strip to form a preliminary splicing.

[0003] As mentioned above, Chinese patent CN220066827U can realize the splicing of the first bus duct body and the second bus duct body with the help of a pre-splicing structure and a lateral fixing mechanism. In actual use, the pre-splicing structure and the lateral fixing mechanism have a limited coverage range, so that there is a gap between the first bus duct body and the second bus duct body after splicing is completed, and the sealing effect is poor. For this reason, the applicant has designed a bus duct splicing mechanism to solve the above problem. Utility Model Content

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] See also Figure 1-5 The utility model provides a technical solution: a splicing mechanism of a bus duct, comprising two bus duct shells 100 and a splicing structure 200 for docking the two bus duct shells 100, the splicing structure 200 comprising two positioning components 210 symmetrically distributed on the left and right and two first pressing plates 220 symmetrically distributed on the upper and lower sides and both covering the docking position laterally, the positioning component 210 comprising two mounting accessories 2110 symmetrically distributed on the upper and lower sides and both assembled on the sides of the docking position and a second pressing plate 2120 clamped between the two mounting accessories 2110 and longitudinally covering the docking position, the mounting accessory 2110 comprising a slot 2111 and two first locking screws 2112 threadedly penetrating the outer wall of the slot 2111, the inner side of the outer wall of the slot 2111 is provided with a first extension edge 2113 distributed along a horizontal plane and in a trapezoidal structure, and the first extension edge 2113 is threadedly penetrated with a second locking screw 2114 for positioning the first pressing plate 220.

[0028] Based on the setting of the above structure, the splicing mechanism of the bus duct is composed of a splicing structure 200 and two bus duct shells 100, wherein the ends of the two bus duct shells 100 are butted together to achieve fixed connection through the splicing structure 200. Specifically, during the installation process, the operator first presses the two second pressing plates 2120 respectively on the left and right sides of the splicing of the two bus duct shells 100, and uses the two installation accessories 2110 to position the two second pressing plates 2120 respectively. The slot 2111 is clamped at the corner of the splicing of the two bus duct shells 100. The operator tightens the two first locking screws 2112 in turn, and the inner ends of the two first locking screws 2112 are pressed against the two bus duct shells 100 respectively, so that the inner side of the inner side wall of the slot 2111 fits with the bus duct shell 100, that is, the installation of the slot 2111 at the splicing is completed, and the two slots symmetrically distributed on the same side are arranged in the upper and lower directions. 2111 is used to position the second pressure plate 2120. After the four card slots 2111 are installed, the two second pressure plates 2120 are pressed onto the left and right sides of the joint respectively. Subsequently, the operator sequentially fits the two first pressure plates 220 onto the top and bottom of the joint respectively, and sequentially tightens the four second locking screws 2114 so that the two first pressure plates 220 are pressed onto the upper and lower sides of the joint respectively, thereby completing the splicing of the two bus duct shells 100. The splicing mechanism of the bus duct is provided with two positioning assemblies 210 symmetrically distributed on the left and right and two first pressure plates 220 symmetrically distributed on the upper and lower sides. Under the action of the mounting accessories 2110 and in conjunction with the second locking screws 2114, the two first pressure plates 220 can be respectively covered horizontally at the joint and the two second pressure plates 2120 can be covered vertically at the joint, thereby ensuring the sealing of the two bus duct shells 100 after the splicing is completed.

[0029] Furthermore, a second extension edge 2115 distributed in the vertical direction and having a trapezoidal structure is provided on the outer side of the inner wall of the slot 2111 away from the docking point, and a third locking screw 2116 is threaded through the second extension edge 2115 for the second pressure plate 2120 to press against the docking point. Among them, the second pressure plate 2120 is clamped between the two installation accessories 2110 in the vertical direction. On the one hand, the second pressure plate 2120 cooperates with the clamping structure to ensure the upper and lower symmetrical relationship of the two installation accessories 2110, which is helpful for the positioning and installation of the installation accessories 2110. On the other hand, the second pressure plate 2120 can ensure the accuracy of the covering position of the second pressure plate 2120 under the limitation of the clamping structure of the two installation accessories 2110. However, in actual use, due to the manufacturing error of the clamping structure, the second pressure plate 2120 may have poor stability and shaking, affecting the sealing effect. Preferably, by providing a second extension edge 2115 and cooperating with the third locking screw 2116 with threads running through the second extension edge 2115, the second pressure plate 2120 can be further limited and fixed, thereby optimizing the pressing effect of the second pressure plate 2120 at the joint and ensuring the sealing.

[0030] Furthermore, both sides of the outer side walls of the two first pressing plates 220 are provided with limiting grooves 2210 for accommodating the ends of the second locking screws 2114. The limiting grooves 2210 are provided, on the one hand, so that the end threads of the second locking screws 2114 penetrate through the first extended edge 2113 and press against the limiting grooves 2210, and the limiting grooves 2210 can limit the ends of the second locking screws 2114, ensuring the firmness and stability of the first pressing plates 220 at the joints, and on the other hand, the two mounting accessories 2110 located at the top or at the bottom can be aligned and calibrated by means of the two limiting grooves 2210, so as to ensure that the two positioning components 210 are symmetrically distributed on the left and right sides, further ensuring the firmness and stability of the overall assembly of the splicing structure 200.

[0031] Furthermore, the inner side of the inner side wall of the slot 2111, the inner side wall of the first pressing plate 220, and the inner side wall of the second pressing plate 2120 are all glued with gaskets 300. Under the action of the first locking screw 2112, the inner side of the inner side wall of the slot 2111 is pressed and fitted with the bus duct housing 100, under the action of the second locking screw 2114, the inner side wall of the first pressing plate 220 is pressed and fitted with the bus duct housing 100, and under the action of the third locking screw 2116, the inner side wall of the second pressing plate 2120 is pressed and fitted with the bus duct housing 100. Preferably, by providing gaskets 300 at the positions of the pressed and fitted contact, effective protection can be provided for the bus duct housing 100.
