[0002] Existing common head-end boxes are either welded or assembled using C-shaped steel. The former increases the workload and is difficult to weld large boxes, making it difficult to ensure welding accuracy. The latter, assembled using C-shaped steel, results in large seams at corners, failing to maintain the required protection level and lacking aesthetic appeal. Furthermore, both types of boxes are made of steel, which is not only heavy and difficult to transport, but also creates closed loops that generate eddy currents and cause localized temperature increases. A new head-end box is urgently needed to address the shortcomings of traditional head-end boxes. Summary of the Invention

[0003] The purpose of the utility model is to provide an assembled starting end box, which makes the unit more convenient to produce, easier to install, lighter in weight and significantly improves the protection level.

[0005] The box frame is composed of frame profiles;

[0006] The top plate covers the upper and lower sides of the box frame and is fixed on the box frame;

[0007] The sealing plate covers the other sides of the box except the upper and lower sides and is fixed on the box frame.

[0008] The feature is that the four edges of the sealing plate are bent inward at right angles, inserted into the groove of the box frame, and contacted with the sealing strip arranged in the groove;

[0009] The box frame also includes corner pieces, which are positioned with the frame profiles by means of concave and convex pieces and fixedly connected by fasteners.

[0010] Furthermore, the frame profile includes frame profile A, which encloses the upper and lower surfaces of the box frame; the frame profile A includes groove 1, groove 2 and through hole A, the groove 1 matches the self-tapping screw, and a sealing strip is set in the groove 2.

[0011] Furthermore, the frame profile includes frame profile B, which is the side support structure of the box frame; the frame profile B includes groove three, groove four and through hole B, the groove four matches the T-shaped or slider nut, and a sealing strip is set in the groove three.

[0012] Furthermore, a boss is provided at the connection between the corner piece and the frame profile, including two bosses 1 and one boss 2, wherein the boss 1 matches the through hole A of the frame profile A, and the boss 2 matches the through hole B of the frame profile B.

[0013] Furthermore, the boss 1 and the boss 2 are different in shape and size, and the ends of the bosses are chamfered.

[0014] Furthermore, the corner piece includes a fixed plate 1 fixedly connected to the frame profile A, the frame profile B, and the closing plate, and the connection positions between the fixed plate 1 and the frame profile A, the frame profile B, and the closing plate are riveted with rivet nuts.

[0015] Furthermore, a sealing gasket is provided on an outer side surface of the fixed plate.

[0016] Furthermore, the corner piece includes a second fixing plate fixedly connected to the frame profile B and the top plate, and a rivet nut is provided at the connection position between the second fixing plate and the frame profile B and the top plate.

[0017] Furthermore, the sealing strip includes a top with a semicircular cross section, a hollow deformation cavity and a bottom with an arrow-shaped cross section.

[0018] Furthermore, it also includes a door panel, and the door panel and the frame profile B are connected by a hinge.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] The starting box involved in the utility model is an assembly structure, which is simple to produce and process, reduces labor costs, improves production efficiency, is simple to assemble, has a reliable structure, and is easy to transport.

[0021] Second, the four sides of the sealing plate are bent to increase the strength. At the same time, it can press the sealing strip to form a seal, so that the box has a higher level of protection. Similarly, the sealing gaskets on the corner pieces can also improve the protection level.

[0022] Third, the corner pieces are equipped with bosses to provide support, preventing the entire force from acting on the bolts and causing deformation of the profile. The bosses are chamfered to facilitate insertion into the through-holes. Bosses 1 and 2 have different shapes to prevent errors.

[0023] Fourth, the plane enclosed by the frame profile A covers the top plate. The groove of the frame profile A is used to fix the top plate with self-tapping screws. Since the profile has grooves along its entire length, it can be fixed to the top plate at any position. Therefore, there is no need to worry about the top plate not matching due to incorrect hole positions during processing.

[0024] Fifth, the profile has grooves and through holes along its entire length, which reduces weight while ensuring structural strength.

[0025] Sixth, frame profile A and frame profile B have the same groove for installing sealing strips. The bottom of the sealing strip is arrow-shaped, which can prevent it from falling after being installed in the groove. The semicircle on the top will be close to the folded edge of the sealing plate when installing the sealing plate. The hollow semicircle can give the sealing plate a certain locking stroke to avoid the solid strip being too hard or the folding error of the sealing plate resulting in insufficient compression and bulging of the door panel plane, affecting the appearance. At the same time, it will also have a better contact effect and enhance the overall sealing. BRIEF DESCRIPTION OF THE DRAWINGS
