Description

Technical Field

[0001] The utility model relates to lamp positioning, and more specifically, to a position limiting fixing structure and a reflector positioning structure. Background Art

[0002] During the installation and fixing process of the lamp, the parts need to be assembled, including the connection forms of snap-on and fastener connection. The connection through fasteners has stronger reliability than the snap-on connection and is also simple and easy to maintain.

[0003] Especially for the connection of the reflector, the reflector will receive a lot of heat during operation, resulting in temperature rise. In the related art, the fixation of the reflector is mostly connected by fasteners.

[0004] The existing reflector has the problem of difficult positioning and poor freedom restriction in the setting of the fastening limit structure position. Workers need to keep the two parts to be connected aligned before fasteners can be connected. This places high demands on the fixture and affects the yield of the product.

[0005] The present application aims to address the deficiencies in the related art and to provide a position limiting and fixing structure to assist in positioning and limit the degrees of freedom, thereby facilitating accurate and reliable installation. Summary of the invention

[0006] The utility model overcomes the shortcomings of the existing fastener's position-limiting and fixing structure, which has poor positioning and freedom restriction, and provides a position-limiting and fixing structure and a reflector positioning structure, which can assist in positioning and freedom restriction, and facilitate accurate and reliable installation.

[0007] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0008] A limiting fixing structure includes a first connector and a second connector, the first connector includes an annular column base for inserting a fastener and a plurality of ribs extending in a radial direction on the outer wall of the annular column base, the second connector includes a first bonding plate bonded to the annular column base, a plurality of second bonding plates bonded to the ribs and an opening concentric with the annular column base for inserting the fastener, when the first connector and the second connector are fixedly connected, the first connector and the second connector are concentrically arranged and the end faces are bonded.

[0009] The first connector and the second connector of the present application are both structures fixedly connected to the two parts to be connected. The function of the first connector and the second connector is to pre-connect the two parts and achieve position limiting in the process. When the two parts are connected, the first bonding plate and the outer wall of the annular column base are bonded to achieve the position limiting effect, limiting the freedom of movement of the two parts in the cross-sectional direction of the annular column base, and only allowing the two parts to move along the axial direction of the annular column base and rotate around the axial direction as the axis.

[0010] When the two parts rotate relative to each other, the rib plate will abut against the second bonding plate, and the cooperation between the rib plate and the second bonding plate plays the role of limiting the aforementioned freedom of rotation about the axial direction.

[0011] The structure achieves the effect of positioning and limiting. The two parts can be pre-positioned by plugging, which is convenient for subsequent fastener connection.

[0012] Preferably, the free end of the annular column base is thin and the fixed end is thick. The structure is small in front and large in the back, which plays a guiding role and facilitates the annular column base to be inserted into the first bonding plate to achieve pre-positioning.

[0013] Preferably, the first bonding plate is an arc plate, and when the first connector and the second connector are fixedly connected, the two ends of the first bonding plate are respectively bonded to the rib plate. The semi-annular ring column of the structure provides an insertion space for the annular column platform. The two ends of the first bonding plate abut against the rib plate, which can also achieve the effect of limiting relative rotation.

[0014] Preferably, there are two ribs, and the two ribs extend out from both ends of the annular column base along a diameter direction respectively.

[0015] Preferably, it further comprises a secondary rib plate, which is arranged along the radial direction, and the angle between the secondary rib plate and the two rib plates is 90 degrees.

[0016] Preferably, there are two second bonding plates, which are respectively located on both sides of the secondary ribs and bonded with adjacent ribs and secondary ribs.

[0017] Preferably, the second bonding plate further has an arc segment, which is located at the corner of the second bonding plate and has the same arc as the outer diameter of the annular column base. The arc segment cooperates with the first bonding plate to form a space for inserting and positioning the annular column base.

[0018] Preferably, the top height of the secondary rib is lower than the top height of the rib, a support column is fixedly connected between the two second bonding plates, and when the first connector and the second connector are fixedly connected, the secondary rib abuts the support column. The structure increases the abutment area and reduces the local pressure when the two parts abut.

[0019] Preferably, the support column and the two second bonding plates are integrally structured, and the support column increases the connection area of ​​the two second bonding plates, thereby achieving a better injection molding effect.

[0020] A reflector positioning structure comprises a reflector body and a connecting structure, wherein the reflector body and the connecting structure are connected via the above-mentioned limiting fixing structure.

[0021] Compared with the prior art, the beneficial effects of the utility model are:

[0022] (1) A space for inserting the annular column base is formed by the first bonding plate, thereby achieving pre-positioning;

[0023] (2) The cooperation between the second bonding plate and the rib plate limits the relative rotation between the parts, facilitating accurate and reliable installation. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] A position limiting and fixing structure comprises a first connecting body 1 and a second connecting body 2.

[0037] The first connector 1 includes an annular column base 3 for inserting fasteners and a plurality of ribs 4 extending in the radial direction and arranged on the outer wall of the annular column base 3. The free end of the annular column base is thin and the fixed end is thick. The structure is small in front and large in the back, which plays a guiding role and facilitates the insertion of the annular column base 3 into the first bonding plate 6 to achieve pre-positioning. Among them, there are two ribs 4, and the two ribs 4 extend at both ends of the annular column base 3 in a diameter direction respectively.

[0038] The second connector 2 includes a first bonding plate 6 bonded to the annular column base, a plurality of second bonding plates 7 for bonding to the rib plate 4, and an opening 8 concentric with the annular column base for inserting fasteners. The first bonding plate 6 is an arc plate. When the first connector 1 and the second connector 2 are fixedly connected, the two ends of the first bonding plate 6 are respectively bonded to the rib plate 4. The semi-annular column of the structure provides an insertion space for the annular column base 3. The two ends of the first bonding plate 6 abut against the rib plate 4 can also achieve the effect of limiting relative rotation.

[0039] In some embodiments, the ribs 4 are also connected with reinforcing ribs 5 to play a supporting and reinforcing role.

[0040] The opening 8 is an oblong hole, and the opening and the annular column base 3 form a channel for the fastener to pass through.

[0041] Embodiment 1:

[0042] The first connecting body 1 includes an annular column 3. Figures 1 to 4 As shown, the annular column base is connected with two ribs 4 along the diameter direction. It also includes a secondary rib 9, which is arranged along the radial direction, and the angle between the secondary rib 9 and the two ribs 4 is 90 degrees. The height of the secondary rib 9 is lower than that of the rib 4.

[0043] There are two second bonding plates 7, which are respectively located on both sides of the secondary rib plate 9 and bonded with the adjacent rib plate 4 and the secondary rib plate 9. The second bonding plate 7 is L-shaped. The second bonding plate 7 also has an arc segment 10, which is located at the corner position of the second bonding plate 7 and has the same arc as the outer diameter of the annular column base. The arc segment 10 cooperates with the first bonding plate 6 to form a space for inserting and positioning the annular column base 3. The top height of the secondary rib plate 9 is lower than the top height of the rib plate 4.

[0044] The second connector 2 is fixedly connected with a support column 11, which is located between the two second connecting plates. When the first connector 1 and the second connector 2 are fixedly connected, the secondary rib plate 9 abuts against the support column 11. The structure increases the abutment area and reduces the local pressure when the two parts abut. The support column 11 is an integral structure with the two second bonding plates 7. The support column 11 increases the connection area of ​​the two second bonding plates 7, thereby achieving a better injection molding effect, and can also increase the connection strength and improve the positioning accuracy.

[0045] When the first connecting body 1 and the second connecting body 2 are fixedly connected, the first connecting body 1 and the second connecting body 2 are concentrically arranged and the end faces are in contact with each other.

The second connector 2 includes an opening 8 of the same size as the inner annular surface of the annular column base 3, and a plurality of first bonding plates 6 and second bonding plates 7 arranged concentrically with the opening 8. Each first bonding plate 6 is arranged at equal intervals, and there is a gap between adjacent first bonding plates 6, and the gap is adapted to the ribs 4. The first bonding plate 6 is integrally connected to the second bonding plate 7, which is arranged in the radial direction and is bonded to the ribs 4.

[0048] The first connector 1 and the second connector 2 of the present application are structures fixedly connected to the two parts to be connected. The function of the first connector 1 and the second connector 2 is to pre-connect the two parts and achieve position limiting in the process. When the two parts are connected, the first bonding plate 6 and the outer wall of the annular column base 3 are bonded to achieve the position limiting effect, limiting the freedom of movement of the two parts in the cross-sectional direction of the annular column base 3, and only allowing the two parts to move along the axial direction of the annular column base 3 and rotate around the axial direction.

[0049] When the two parts rotate relative to each other, the rib plate 4 will abut against the second bonding plate 7, and the cooperation between the rib plate 4 and the second bonding plate 7 plays the role of limiting the aforementioned freedom of rotation about the axial direction.

[0050] The structure achieves the effect of positioning and limiting. The two parts can be pre-positioned by plugging, which is convenient for subsequent fastener connection.
