Description

Technical Field

[0001] The utility model belongs to the technical field of composite material products, in particular to an SMC box body with a box door which is convenient to open and close. Background Art

[0002] The current opening and closing method of the cylindrical connection between the box body and the box door is that a cylindrical pin penetrates the box body and the box door to form a movable structure to achieve free opening and closing of the box door and the box body. This method requires through holes to be drilled in both the box body and the box door at the same time. This method is extremely inconvenient in the use of SMC molded boxes, and requires secondary drilling, which increases the workload and cannot guarantee the accuracy of the hole size and the product appearance. In addition, based on the SMC box in the prior art, its door is prone to loosening during actual use, resulting in poor stability and sealing of the mechanism itself, which is very likely to affect the safety of the use of the facilities inside the box. Therefore, we have made technical improvements to the SMC box on the basis of the existing technology to solve the above problems. Utility Model Content

[0003] The utility model aims to provide an SMC box body with a box door that is convenient to open and close, so as to solve the problems of complex processing procedures and poor structural stability of the existing molded box body.

[0005] The utility model discloses an SMC box body with a door that is convenient to open and close, comprising a working box, a closed door and an adjusting handle, wherein a mounting opening is provided on one side of the working box, wherein the closed door is arranged inside the mounting opening and folded with the closed door; two mounting blocks are bolted and fixed on one surface of the closed door, the adjusting handle is hinged between the two mounting blocks, and the adjusting handle and the closed door cooperate with each other; the technical scheme mainly combines the common SMC box bodies in the prior art and improves it more conveniently, wherein the working box and the closed door are an assembled structure, and the connection method between the two in the prior art usually requires a through hole to be opened on the box body of the working box, and a swivel is used to connect the working box and the closed door, while in the technical scheme, only mounting grooves on both sides need to be reserved during the pressing process of the box body of the working box, thereby reducing the risk of hole opening error.

[0006] Furthermore, the two opposite inner walls of the installation opening are provided with installation grooves and locking grooves, wherein the two installation grooves are positioned opposite to each other, the two locking grooves are positioned opposite to each other, and the installation grooves are arranged above the locking grooves; the upper end of the closed door is provided with installation cavities on the two opposite side surfaces, and the interior of the installation cavity is slidably engaged with a support pin, wherein a support spring is arranged between one end of the support pin and the inner surface of the installation cavity, and the other end extends to the interior of the installation groove through the installation cavity; combined with the above-mentioned structure, the working box and the closed door cooperate with each other through the support pin and the installation groove to form an assembled hinge structure, and during assembly, it is only necessary to push the support pin into the interior of the installation cavity in advance, and then align the installation cavity with the installation groove, so that the support pin automatically pops into the installation groove under the action of the support spring to complete the assembly.

[0007] Furthermore, locking cavities are provided on both opposite sides of the lower end of the closed door, and a locking pin is slidably engaged inside the locking cavity, and the locking pin and the locking groove cooperate with each other; combined with the aforementioned structure, when the SMC box in the present technical solution is assembled, when the closed door is in the closed state, the locking pin is inserted into the locking groove, so that the closed door can complete the closing of the working box.

[0008] Furthermore, a transmission cavity is opened inside the closed door, wherein the transmission cavity is connected with the locking cavity; two driven rods are slidably engaged inside the transmission cavity, wherein a driven plate is welded to one end of the driven rod, and the other end slides through the transmission cavity to extend to the inside of the locking cavity, and is spirally connected and fixed with the locking pin, so as to facilitate quick assembly between the driven rod and the locking pin.

[0009] Furthermore, one side of the transmission cavity is connected to the outside of the closed door; the adjusting handle is a "U"-shaped handle structure, and a hinge rod is fixedly connected between its two relatively inner side surfaces, and the hinge rod is a threaded rod structure, and is meshed with the driven plate through the transmission cavity; a connecting spring is welded between the two relatively driven plates; two sections of thread grooves are opened on the surface of the hinge rod, which correspond to the two driven plates respectively, and the opening directions of the two sections of thread grooves are opposite; a limit spring is welded and fixed between the locking pin and the locking cavity, and the limit spring is slidably nested on the outside of the driven rod; combined with the above structure, in actual work, the hinge rod is driven to rotate by rotating the adjusting handle, and then the driven rod is driven to slide inside the transmission cavity through the meshing structure of the hinge rod and the two driven plates, thereby controlling the extension and retraction of the locking pin, thereby achieving the effect of locking and unlocking the closed door.

[0010] The utility model has the following beneficial effects:

[0011] This technical solution mainly combines the common SMC box in the prior art and makes a more convenient improvement thereto, wherein the working box and the closed door are assembled structures. In the prior art, the connection method between the two usually requires opening a through hole on the box of the working box and using a swivel to connect the working box and the closed door. In this technical solution, only the installation grooves on both sides need to be reserved during the pressing process of the box of the working box, thereby reducing the risk of hole opening error;

[0012] Among them, the utility model forms an assembled hinge structure by arranging a support pin and an installation slot between the working box and the closed door to cooperate with each other. When assembling, it is only necessary to push the support pin into the interior of the installation cavity in advance, and then align the installation cavity with the installation slot, so that the support pin automatically bounces into the installation slot under the action of the support spring to complete the assembly;

[0013] In addition, by setting an adjustment handle, rotating the adjustment handle drives the hinge rod to rotate, and then the engagement structure between the hinge rod and the two driven plates drives the driven rod to slide inside the transmission cavity, thereby controlling the extension and retraction of the locking pin, thereby achieving the effect of locking and unlocking the closed door.

[0014] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

During assembly, it is only necessary to push the support pin 9 into the interior of the mounting cavity 8 in advance, and then align the mounting cavity 8 with the mounting groove 6, so that the support pin 9 automatically pops into the mounting groove 6 under the action of the support spring 10 to complete the assembly.

[0029] Preferably, locking cavities 11 are provided on both opposite sides of the lower end of the closed door 2, and a locking pin 12 is slidably engaged inside the locking cavity 11, and the locking pin 12 cooperates with the locking groove 7; combined with the aforementioned structure, when the SMC box in the present technical solution is assembled, when the closed door 2 is in the closed state, the locking pin 12 is inserted into the locking groove 7, so that the closed door 2 can complete the closing of the working box 1.
