[0025] 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.

[0026] Example

[0027] See Figures 1 to 4 As shown, a bulb lamp housing structure includes an upper housing 1 and a lower housing 2. A connecting cylinder 3 for connecting a lamp holder is fixed on the top of the upper housing. In this embodiment, the upper housing is a plastic structure, and the lower housing is a light-transmitting plastic structure or an acrylic structure. The connecting cylinder is mainly used to connect the lamp holder, and the lamp holder can be fixed by riveting or by glass glue.

[0028] In actual application, a plurality of strip grooves 4 are provided at the lower part of the side wall of the upper shell; and the plurality of strip grooves are on the same circular ring; an n-shaped clamping spring 5 is provided on the upper shell, and the transverse part of the n-shaped clamping spring is in the strip groove; the number of the strip grooves is three or four. In this embodiment, the n-shaped clamping spring is a stainless steel sheet with a thickness of 0.1-0.5 mm. The width of the opening of the n-shaped clamping spring is smaller than the thickness of the upper shell and the lower shell. When in use, the elastic force of the n-shaped clamping spring can be used to quickly clamp the lower shell, and the disassembly operation is also convenient.

[0029] In actual application, the top of the lower shell is integrally formed with a convex strip 6; during installation, the upper outer surface of the lower shell is attached to the inner wall of the upper shell, and the convex strip is inserted into the n-shaped clamping spring for positioning. The convex strip can ensure the stability of the connection and prevent loosening or falling off. When the external force is greater than the spring of the n-shaped clamping spring, the lower shell can fall off from the upper shell, which improves the stability of installation and the convenience of disassembly.

[0030] In actual application, the two vertical parts of the n-shaped clamping spring are bent to form a C-shaped clamping protrusion 7, and the arched part of the C-shaped clamping protrusion is in the concave area of ​​the n-shaped clamping spring; the C-shaped clamping protrusion is clamped under the convex strip to achieve positioning. The C-shaped clamping protrusion is mainly used to increase the clamping force of the clamping point, and cooperates with the convex strip to ensure the stability and reliability of installation.

[0031] In actual application, in order to prevent light from escaping from the strip groove, an arc-shaped shielding sheet 8 is provided on the inner wall of the upper shell; the arc-shaped shielding sheet is located inside the strip groove. The arc-shaped shielding sheet can prevent light from entering the strip groove, thereby ensuring the effectiveness of lighting.

[0032] In actual application, a plurality of heat dissipation fins 9 are arranged on the outer wall of the upper shell. A limiting convex ring 10 is arranged on the outer wall of the lower shell, and the bottom surface of the upper shell is positioned at the upper limit of the limiting convex ring. The limiting convex ring is mainly used to limit the position when the upper shell and the lower shell are connected, and the convex strip can ensure the stability and reliability of the connection between the upper shell and the lower shell.

[0033] The utility model has positive effects: the structure of the utility model is reasonably arranged. A strip groove is arranged on the upper shell body, and an n-shaped clamping spring is matched. When in use, the lower shell body is clamped between the n-shaped clamping spring and the inner wall of the upper shell body, and the n-shaped clamping spring is clamped and positioned on the bottom surface of the convex strip, which improves the convenience and stability of disassembly and assembly, and can also improve the effectiveness of the connection between the upper shell body and the lower shell body. It is not easy to loosen or fall off, and has strong practicality.

[0034] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural components recorded in the specification can also be directly processed according to existing technical common sense. At the same time, the connection method of each component adopts the mature conventional means in the prior art, and the machinery, parts and equipment all adopt the conventional models in the prior art, so no specific description will be given here.

[0035] Obviously, the above embodiments of the present invention are merely examples for clearly explaining the present invention, and are not intended to limit the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. However, these obvious changes or modifications derived from the essential spirit of the present invention still belong to the protection scope of the present invention.
