Technical Field

[0001] This utility model relates to the field of mechanical technology, specifically to a lamp cover tightening fixture. Background Technology

[0002] Explosion-proof lighting fixtures are typically large in size, which results in the lamp cover and lamp body being also relatively large.

[0003] In practice, it usually requires two workers to work together. One worker fixes the lamp body, while the other worker rotates the lamp cover to perform the assembly work.

[0004] When connecting and installing the lamp cover to the lamp body, the traditional manual tightening method is inefficient and makes it difficult to ensure the uniformity and stability of the connection between the lamp cover and the lamp body. Utility Model Content

[0005] The purpose of this utility model is to address the aforementioned problems in existing technologies by providing a simple and labor-saving lamp cover tightening fixture.

[0006] To achieve the above objectives, this utility model can be implemented through the following technical solutions:

[0007] A lamp cover tightening fixture is characterized in that it includes a collar and a handle. The collar includes an annular ring body with several protruding teeth on the inner side of the ring body. The outer side of the ring body also has a rod-shaped connecting rod. The handle is made of flexible material and has a recessed connecting hole at the inner end of the handle. The connecting rod is embedded in the connecting hole and a connecting component is provided between the connecting rod and the handle to lock the two together.

[0008] In the aforementioned lamp cover tightening fixture, the ring and the connecting rod are an integral structure.

[0009] In the aforementioned lamp cover tightening fixture, the connecting rod is prismatic in shape, and the connecting hole on the handle matches the connecting rod.

[0010] In the aforementioned lamp cover tightening fixture, the handle is arc-shaped.

[0011] In the aforementioned lamp cover tightening fixture, the arc-shaped protrusion of the handle has a contact portion with a concave-convex shape.

[0012] In the aforementioned lamp cover tightening fixture, the contact part is a ring-shaped recessed groove on the protruding part of the handle.

[0013] In the above-mentioned lamp cover tightening fixture, the contact part also includes several protrusions protruding from the outside of the handle. The protrusions are evenly distributed along the length of the handle and all protrusions are located in the annular inner area of ​​the groove.

[0014] In the aforementioned lamp cover tightening fixture, the inner end of the handle has an annular protruding retaining edge.

[0015] In the aforementioned lamp cover tightening fixture, the connecting assembly includes a positioning recess recessed on the side of the connecting rod and a spring hole recessed in the handle. The spring hole contains a spring and a ball. Under the elastic force of the spring, the ball tends to be embedded in the positioning recess.

[0016] In the above-mentioned lamp cover tightening fixture, there are several connecting components, which are evenly distributed along the length of the connecting hole.

[0017] Compared to existing technologies, this lamp cover tightening fixture features a detachable connection between the collar and handle. Therefore, the fixture can be disassembled when not in use, avoiding excessive storage space. Simultaneously, the flexible handle improves comfort during operation, preventing cuts or scratches to the operator's hands caused by the rigid collar. The fixture allows for faster and more comfortable tightening of the lamp cover, making the operation more effortless for the operator.

[0018] In addition, the contact part on the handle can appropriately increase the friction between the operator's hand and the handle during operation, ensuring a more stable tightening of the lamp cover, which has high practical value. Attached Figure Description

[0025] The following are specific embodiments of the present invention, and the technical solution of the present invention will be further described in conjunction with the accompanying drawings.

[0026] like Figure 1-4As shown, the lamp cover tightening fixture includes a collar and a handle 3. The collar includes an annular ring body 1 with several protruding teeth 11 on the inner side of the ring body 1. The outer side of the ring body 1 also has a rod-shaped connecting rod 2. The handle 3 is made of flexible material and has a recessed connecting hole 31 at the inner end of the handle 3. The connecting rod 2 is embedded in the connecting hole 31 and there is a connecting component between the connecting rod 2 and the handle 3 that can lock the two together.

[0027] The collar is made of a rigid metal material; in this embodiment, the collar is made of aluminum alloy. The collar made of aluminum alloy not only has sufficient strength but is also relatively lightweight.

[0028] The handle 3 is made of flexible material; in this embodiment, the handle 3 is made of rubber.

[0029] The inner cavity of the ring 1 matches the outer side of the lamp cover; that is, the outer edge of the lamp cover has a groove-like structure that matches the teeth. Once the ring 1 is fitted onto the lamp cover, a stable circumferential fixed connection is formed between the ring 1 and the lamp cover.

[0030] Next, the operator holds the flexible handle 3 and applies external force to stably rotate the ring 1. The lamp cover connected to the ring 1 rotates along with it, thus completing the connection between the lamp cover and the lamp body. Of course, the lamp cover and the lamp body are connected by a threaded connection, so the operator needs to apply external force to make the ring rotate 360 ​​degrees a set number of times.

[0031] Once the lamp cover is connected to the lamp body, an external force is applied to move the collar along its axis, and the collar is then stably separated from the lamp cover.

[0032] During the assembly process described above, the operator simply supports the lamp body with one hand and holds the handle with the other, turning it as needed. Therefore, the entire operation can be completed by a single person.

[0033] The ring 1 and the connecting rod 2 are an integral structure.

[0034] This can appropriately improve the structural compactness of the collar.

[0035] The connecting rod 2 is prismatic in shape, and the connecting hole 31 on the handle 3 matches the connecting rod 2.

[0036] This structure prevents the collar from rotating relative to handle 3.

[0037] The handle 3 is arc-shaped.

[0038] The curved handle 3 is ergonomic, which not only maximizes the contact area of ​​the operator's hands, but also makes the grip more stable.

[0039] The outwardly protruding arc of the handle 3 has a contact portion with a concave-convex shape.

[0040] The contact part is a groove 4 that is annularly recessed at the protruding part of the handle 3.

[0041] The groove 4 makes the contact part concave and convex, which effectively increases the friction between the contact part and the operator's hand.

[0042] The contact portion also includes several protrusions 5 protruding from the outside of the handle 3. The protrusions 5 are evenly distributed along the length of the handle 3 and all protrusions 5 are located in the annular inner area of ​​the groove 4.

[0043] The multiple adjacent protrusions 5 further increase the friction between the operator's hand and the handle 3 during operation.

[0044] The handle 3 has an annular protruding flange 6 at its inner end.

[0045] The baffle 6 prevents the operator's hand from accidentally crossing the handle 3 and touching the rigid collar during the rotation of the handle 3.

[0046] The connecting assembly includes a positioning recess 21 recessed on the side of the connecting rod 2 and a spring hole 7 recessed in the handle 3. The spring hole 7 contains a spring 8 and a ball 9. Under the elastic force of the spring 8, the ball 9 tends to be embedded in the positioning recess 21.

[0047] Under the elastic force of spring 8, linkage 2 and handle 3 can be positioned together. Of course, when a sufficiently large external force is applied, linkage 2 can push against spring 8 and stably disengage from handle 3.

[0048] The number of connecting components is several, and the several connecting components are evenly distributed along the length direction of the connecting hole 31.

[0049] The arrangement of multiple connecting components can further improve the connection stability between handle 3 and link 2.

[0050] The above-described technical solution of this utility model addresses the problem that existing technical solutions are too simplistic and provides a solution that is significantly different from existing technologies. The parts not covered in this application's technical solution are the same as or can be implemented using existing technologies, and will not be described in detail here.
