Description

Technical Field

[0001] The utility model belongs to the technical field of generators, and particularly refers to a floating installation structure for the top cover of a generator. Background Art

[0002] Digital variable-frequency generators are used as small portable power sources in many occasions. Existing digital variable-frequency generators include a housing assembly and components such as a power assembly and a fuel tank arranged inside the housing assembly. The housing assembly includes a top cover arranged above the fuel tank, and the left and right sides of the top cover are fixedly connected to the corresponding side plates respectively. For example, the Chinese Patent Network discloses a generator fuel tank and power assembly installation system [Application No.: 202011608015.8], which includes an outer frame, a power assembly, and a fuel tank. The outer frame is formed by enclosing a chassis, a top cover, a front cover, a rear cover, a left housing, and a right housing to form an accommodation cavity. The power assembly and the fuel tank are installed inside the accommodation cavity. The fuel tank and the power assembly are arranged together in the vertical space between the chassis and the top cover. The fuel tank is located directly above the power assembly. The fuel tank and the power assembly are separately arranged. The fuel tank is supported and installed through the top cover, the front cover, the rear cover, the left housing, and the right housing. The power assembly is supported and installed on the chassis. The rear end of the top cover has a rear edge that slopes downward, and the left and right sides of the rear edge have rear buckling parts connected to the left housing and the right housing. The left and right sides of the rear end of the top cover are connected to the left housing and the right housing through the rear buckling parts, and the entire rear edge is arranged inward in the rear concave area. Since the top cover is connected to the left housing and the right housing by a snap connection, the strength of this snap connection structure is not high, and there is a risk of detachment between the top cover and the left housing and the right housing.

[0003] There is also a method of connecting the top cover to the left housing and the right housing through fasteners. Specifically, connection holes are opened on the top cover, and installation holes are also opened on the housing. During assembly, the connection holes and the installation holes are coaxially arranged. After the fasteners pass through the connection holes and the installation holes, the top cover and the housing are fixedly connected. However, since the top cover, the left housing, and the right housing are all made of plastic materials, there is a certain degree of deformation after the top cover, the left housing, and the right housing are formed, which leads to the inability to accurately align the connection holes and the installation holes. There is a certain degree of misalignment between the connection holes and the installation holes, making it difficult for the fasteners to pass through the connection holes and the installation holes, resulting in inconvenient assembly. Summary of the Utility Model

[0004] The purpose of the present utility model is to address the above problems existing in the prior art and propose a floating installation structure for the top cover of a generator. The technical problem to be solved by the present utility model is: how to improve the convenience of installing the top cover between the left housing and the right housing.

[0005] The purpose of the present utility model can be achieved by the following technical solutions:

[0006] A floating installation structure for the top cover of a generator, comprising a top cover, a left housing and a right housing. A handle rod is provided at the end of the top cover, and the handle rod can rotate relative to the top cover. It is characterized in that floating connection structures are provided between one end of the handle rod and the left housing and between the other end of the handle rod and the right housing respectively; the floating connection structure includes a connection bracket and a stepped screw. The connection bracket is connected to the left housing or the right housing through a fastener. The stepped screw is screwed at the end of the handle rod. The connection bracket has a connection boss, and the connection boss has a first mounting hole. The connection boss is sleeved on the stepped screw through the first mounting hole, and the connection bracket can swing forward and backward by a certain angle.

[0007] The handle rod of the generator is used for the staff's hand to hold when carrying the generator. Connection brackets are connected to both ends of the handle rod of this structure. The connection bracket and the handle rod are connected by a stepped screw. When the connection bracket swings forward or backward, the handle rod serves as a swing axis, and the handle rod rotates relative to the top cover, thereby causing the connection bracket to swing forward or backward; the left housing or the right housing and the connection bracket are both connected by fasteners, that is, mounting hole positions are provided on both the housing and the connection bracket. During the installation process, in order to eliminate the forming error between the top cover and the housing, with the housing position unchanged, the connection bracket can be swung forward or backward by a certain angle to accurately align the mounting hole position on the housing with the mounting hole position on the connection bracket, thereby facilitating the smooth insertion of the fastener into the mounting hole positions on the housing and the connection bracket, improving the convenience of installation; in addition, the connection bracket in this structure is made of metal material and has high structural strength, thereby ensuring good structural strength and stability of the connection between the top cover and the housing.

[0008] In the above floating installation structure for the top cover of a generator, the connection boss can move axially along the stepped screw. The connection bracket in this structure can move axially along the stepped screw, thereby realizing a slight up and down movement of the connection bracket, further realizing the dynamic adjustment of the position of the connection bracket, and further ensuring the accurate alignment of the mounting hole position on the housing with the mounting hole position on the connection bracket.

[0009] In the above floating installation structure for the top cover of a generator, the connection bracket has a connection part, and a connection hole is provided on the connection part. The end of the handle rod is inserted into the connection hole, and the connection boss is arranged on the connection part and is located below the handle rod. The setting of the connection hole facilitates the rotation of the handle rod, reduces the force on the boss screw, and the connection boss located below the handle rod does not interfere with the rotation of the handle rod.

[0010] In the floating mounting structure of the top cover of the generator described above, a second mounting hole is provided at the lower end of the connecting bracket, and third mounting holes are provided at the positions of the left housing and the right housing corresponding to the second mounting hole. During assembly, fasteners pass through the third mounting hole and the second mounting hole, so that the housing is fixedly connected to the connecting bracket.

[0011] In the floating mounting structure of the top cover of the generator described above, there are two second mounting holes, and the two second mounting holes are dispersedly arranged. There are two third mounting holes on both the left housing and the right housing, and the third mounting holes correspond to the second mounting holes. One of the fixed points of this connecting bracket is fixedly connected to the lifting rod through a stepped screw, and the other two dispersed fixed points are fixedly connected to the housing through fasteners, ensuring that the connecting bracket is positioned and will not displace, and ensuring the connection stability between the top cover and the housing.

[0012] In the floating mounting structure of the top cover of the generator described above, a connecting seat is fixed at the position of the back surface of the connecting bracket corresponding to the second mounting hole. A threaded hole is provided on the connecting seat, and the threaded hole is coaxially arranged with the second mounting hole. During assembly, after the fastener passes through the third mounting hole and the second mounting hole, it is threadedly connected to the threaded hole. The setting of the connecting seat facilitates the connection and fixation of the fastener.

[0013] In the floating mounting structure of the top cover of the generator described above, limit seats and limit plates are provided on the inner walls of both the left housing and the right housing. The limit seat has a guiding surface and a limiting surface. The guiding surface is used to contact the side edge of the limiting part and guide the limiting part to move between the limiting surface and the limit plate. During assembly, the housing and the top cover are brought close to each other and pressed. The side edge of the limiting part first contacts the guiding surface and moves along the guiding surface to between the limiting surface and the limit plate, so that the limiting part is limited between the limiting surface and the limit plate. The second mounting hole in this structure is provided on the limiting part, thereby ensuring that the second mounting hole can be accurately aligned with the third mounting hole, and further improving the convenience of assembly.

[0014] Compared with the prior art, the floating mounting structure of the top cover of the generator of the present utility model has the following advantages: During the installation process, in order to eliminate the forming error between the top cover and the housing, with the position of the housing unchanged, the connecting bracket can be swung forward or backward by a certain angle to accurately align the mounting hole positions on the housing with the mounting hole positions on the connecting bracket, thereby facilitating the smooth insertion of the fasteners into the mounting hole positions on the housing and the connecting bracket, improving the convenience of installation; In addition, the connecting bracket in this structure is made of metal material and has high structural strength, thereby ensuring that the connection between the top cover and the housing has good structural strength and stability.
