[0033] Reference Figures 1 to 5 This utility model provides a lamp housing, comprising a housing body 100 and a housing cover 200. The housing body 100 has an upward-facing mounting cavity 110 with an opening 111. The mounting cavity 110 contains two mounting platforms 120, each with a clamping part 300. The side wall of the mounting cavity 110 has four slots 112. The side wall of the housing cover 200 has four locking blocks 210. The housing cover 200 is rotatably mounted in the mounting cavity 110 through the opening 111. The four locking blocks 210 are inserted into the four slots 112 one-to-one to restrict the longitudinal movement of the housing cover 200. The clamping part 300 abuts against the housing cover 200 to press against the housing body 100 and the housing cover 200. The housing cover 200 can rotate relative to the housing body 100, causing the four locking blocks 210 to move away from the four slots 112 one-to-one, so that the housing cover 200 can be pulled out upward from the opening 111.

[0034] It is understandable that the process of rotating and inserting the cover 200 into the shell body 100 is as follows: 1. Insert the cover 200 into the mounting cavity 110 through the opening 111; 2. Rotate the cover 200 so that the four locking blocks 210 are inserted into the four locking slots 112 one by one. At this time, the abutting part 300 abuts against the cover 200 to tighten the shell body 100 and the cover 200.

[0035] It is understandable that the process of removing the cover 200 from the shell body 100 is as follows: 1. Drive the cover 200 to rotate relative to the shell body 100, so that the four locking blocks 210 move away from the four locking slots 112 one by one; 2. Drive the cover 200 to be pulled upward through the opening 111. At this time, the contact between the pressing part 300 and the cover 200 is released.

[0036] With the above structure, the clamping part 300 located on the mounting platform 120 can abut against the shell cover 200, so that a continuous clamping force can be formed after the locking block 210 and the locking groove 112 are inserted, so as to effectively eliminate the loose gap of the traditional rotary plug-in structure, ensure the tight connection between the shell body 100 and the shell cover 200, and improve the connection stability between the shell body 100 and the shell cover 200.

[0037] In some embodiments, the number of card slots 112 and card blocks 210 is set to three, etc.

When the four locking blocks 210 are inserted into the four locking slots 112 in a one-to-one correspondence, the two abutting parts 300 abut against the two mounting platforms 120 in a one-to-one correspondence to tighten the shell body 100 and the shell cover 200.

[0040] In some embodiments, the mounting platform 120 has an annular structure, and both the shell cover 200 and the mounting platform 120 are provided with abutting portions 300. When the four locking blocks 210 are inserted into the four locking slots 112 in a corresponding manner, the abutting portions 300 on the shell cover 200 abut against the mounting platform 120 to tighten the shell body 100 and the shell cover 200. The abutting portions 300 on the mounting platform 120 abut against the shell cover 200 to tighten the shell body 100 and the shell cover 200.

[0041] In this embodiment, refer to Figure 2 and Figure 4 The tight part 300 has a spherical crown-shaped structure.

[0042] Furthermore, in this embodiment, referring to Figure 2 and Figure 5 The cover 200 is provided with a groove 220 that cooperates with the abutment 300. The number of grooves 220 is set to two. The two abutments 300 are respectively provided in the two grooves 220 of the cover 200 and abut against the bottom of the grooves 220 to press the shell body 100 and the cover 200 tightly.

[0043] With the above structure, the spherical crown-shaped clamping part 300 is provided in the corresponding groove 220, so as to restrict the rotation of the shell cover 200 relative to the shell body 100 to a certain extent, thereby further improving the connection stability of the rotating shell body 100 and the shell cover 200.

[0044] In some embodiments, both abutting portions 300 are provided on the shell cover 200, and both mounting platforms 120 are provided with grooves 220 that cooperate with the abutting portions 300. The two abutting portions 300 are provided one-to-one with the grooves 220 on the two mounting platforms 120, and respectively abut against the bottom of the grooves 220 to press against the shell body 100 and the shell cover 200.

[0045] In this embodiment, refer to Figure 2 The cover 200 is rotatably abutted against the mounting platform 120 through the opening 111. It can be understood that the cover 200 abuts against the mounting platform 120 while simultaneously abutting against the clamping part 300 on the mounting platform 120.

[0046] In some embodiments, the cover 200 abuts only against the abutment 300 on the mounting platform 120.

[0047] In this embodiment, refer to Figure 1 The top side of the cover 200 is provided with a bracket 400, which can be used to mount lamps using the lamp housing of this application.
