Description

Technical Field

[0001] This utility model relates to the field of mechanical technology, and more specifically to a lampshade mounting clamp. Background Technology

[0002] Explosion-proof lighting fixtures are lighting devices specifically designed for use in hazardous environments where explosive gases, vapors, or dust may be present. These fixtures are designed and manufactured in strict accordance with specific safety standards to ensure they will not become ignition sources, thereby preventing explosions.

[0003] Because some explosion-proof lights are quite large, at least two workers are needed to install the lamp housing and lamp cover. One worker positions the lamp housing, and the other worker fastens the lamp cover onto the lamp housing for assembly.

[0004] It can be seen that the above-mentioned operation method requires a lot of manpower and the tacit cooperation of multiple operators, which makes the assembly difficult and the assembly efficiency relatively low. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned problems in existing technologies by providing a lampshade mounting clamp that can stably position lamps during the process of a single person loading and unloading lampshades.

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

[0007] A lampshade mounting clamp includes a long plate-shaped base plate, characterized in that it further includes a positioning part one, a positioning part two, a positioning part three, and a clamping assembly. The positioning parts one, two, and three are all fixed to the upper part of the base plate. The positioning parts one and three are symmetrically distributed at both ends of the base plate. The positioning part two is located on the side of the line connecting the positioning parts one and three. There are two clamping assemblies, and the two clamping assemblies are respectively adjacent to the positioning parts one and three. The positioning part two has a buffer assembly that can make buffer contact with the lamp.

[0008] In the above-mentioned lampshade mounting fixture, the first positioning part is a positioning rod 1 fixed to one end of the substrate and in the shape of a round rod, the third positioning part is a positioning rod 3 fixed to the other end of the substrate and in the shape of a round rod, the second positioning part is a positioning rod 2 fixed to the middle of the substrate and in the shape of a round rod, and the number of the second positioning rods is at least two and several second positioning rods are arranged adjacent to each other.

[0009] In the lampshade mounting fixture described above, the line connecting positioning rod one and positioning rod three is parallel to the line connecting the two positioning rods two.

[0010] In the above-mentioned lampshade mounting fixture, the buffer component is a flexible sleeve, and each positioning rod is fitted with a sleeve.

[0011] In the above-mentioned lampshade mounting fixture, the sleeve is made of rubber.

[0012] In the above-mentioned lampshade mounting fixture, the sleeve is a piece of fabric covering the positioning rod two.

[0013] In the aforementioned lampshade mounting fixture, the clamping assembly includes a base, a pressure head, a handle, and a connecting rod. The lower part of the base is fixed to the base plate. The two ends of the base have protruding hinge portion one and hinge portion two, respectively. The lower part of the inner end of the pressure head is hinged to hinge portion one. The inner end of the handle is hinged to the upper part of the inner end of the pressure head. The two ends of the connecting rod are hinged to the middle of the handle and hinge portion two, respectively. When an external force is applied to make the outer end of the handle swing down and abut against hinge portion two, a parallelogram structure with four-point hinges is formed between the base, pressure head, handle, and connecting rod, and the structure is in a locked state at this time.

[0014] In the above-mentioned lampshade mounting fixture, the protruding connecting part on the side of the base also includes a support rod, the upper end of which is fixedly connected to the connecting part, and the lower end of which is fixedly connected to the substrate.

[0015] In the lampshade mounting fixture described above, the connecting part has at least two support rods along its length.

[0016] In the lampshade mounting fixture described above, both sides of the base have protruding connecting parts, and each connecting part has several support rods.

[0017] Compared to existing technologies, this lampshade mounting fixture positions the lamp housing on both sides using positioning part one and positioning part three, and on the rear side using positioning part two. Therefore, the lamp housing to be assembled can be directly pushed onto the substrate, and the three positioning parts provide stable positioning. It can be seen that during assembly, only one operator is needed to position the lamp housing between the three positioning parts on the substrate. Because the positioned lamp housing is fixed, subsequent lampshade assembly can proceed smoothly and quickly. Clearly, this lampshade mounting fixture allows one operator to quickly complete the installation of the lampshade for explosion-proof lighting fixtures, saving labor and increasing efficiency.

[0018] Meanwhile, the clamping assembly further stabilizes the lamp housing. In other words, the three positioning parts initially position the lamp housing, and the clamping assembly achieves final stable positioning, effectively improving the positioning stability of the lamp housing and ensuring that the lamp housing will not loosen during the installation of the lampshade and the lamp housing, which has high practical value.

[0024] 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.

[0025] like Figure 1-3 As shown, the lampshade mounting fixture includes a long plate-shaped base plate 1, and also includes a positioning part one, a positioning part two, a positioning part three, and a clamping assembly. The positioning parts one, two, and three are all fixed to the upper part of the base plate 1. The positioning parts one and three are symmetrically distributed at both ends of the base plate 1. The positioning part two is located on the side of the line connecting the positioning parts one and three. There are two clamping assemblies, and the two clamping assemblies are adjacent to the positioning parts one and three, respectively. The positioning part two has a buffer assembly that can make buffer contact with the lamp.

[0026] The first positioning part is a positioning rod 2 fixed to one end of the substrate and in the shape of a round rod. The third positioning part is a positioning rod 4 fixed to the other end of the substrate and in the shape of a round rod. The second positioning part is a positioning rod 3 fixed to the middle of the substrate and in the shape of a round rod. The number of the second positioning rods 3 is at least two and several second positioning rods 3 are arranged adjacent to each other.

[0027] Explosion-proof lighting fixtures include a lamp housing and a lamp cover. This clamp is used to position the lamp housing in the explosion-proof lighting fixture. Once the lamp housing is positioned, the fixed lamp housing can facilitate the subsequent installation of the lamp cover and the lamp housing.

[0028] Since explosion-proof lighting fixtures are existing technology and are commercially available components, their specific structure will not be described in this embodiment.

[0029] This embodiment can position both rectangular and circular lamp housings.

[0030] When the lamp housing is rectangular, positioning rod 1 (2) and positioning rod 3 (4) are positioned on the left and right sides of the lamp housing, while positioning rod 2 (3) is positioned on the rear side of the lamp housing.

[0031] Because the contact area between positioning rod 1, 2 and positioning rod 3, 4 and the lamp housing is relatively small, but there are multiple positioning rods 2, 3, each of which abuts against the rear side of the lamp housing, the lamp housing being positioned will not rotate or swing on this fixture.

[0032] When the lamp housing is round, positioning rod 1 (2) and positioning rod 3 (4) are positioned on the left and right sides of the lamp housing, and two positioning rods 2 (3) are positioned on the rear side of the lamp housing.

[0033] As can be seen, both rectangular and round lamp housings can be stably positioned by this fixture.

[0034] In actual assembly operations, there are two scenarios:

[0035] Firstly, for applications requiring low positioning accuracy, positioning can be achieved using only three positioning units.

[0036] Secondly, when the positioning accuracy requirement is relatively high, the three positioning parts pre-position the lamp housing, and then the lamp housing is positioned by the clamping assembly.

[0037] For assembly operations requiring high positioning accuracy, the lamps must have protruding edges on their housings, and the clamping assembly must press these protruding edges firmly onto the substrate. Similarly, lamps with protruding edges are already commercially available components, and will not be described in detail in this embodiment.

[0038] The line connecting positioning rod 1 (2) and positioning rod 3 (4) is parallel to the line connecting the two positioning rods 2 (3).

[0039] This structure allows the lamp housing to be stably positioned.

[0040] The buffer assembly is a flexible sleeve 5, and each positioning rod 3 is fitted with a sleeve 5.

[0041] The flexible sleeve 5 not only prevents the lamp from rigidly contacting the positioning rod 2 3, but also effectively eliminates the gap between the lamp housing and the positioning rod 2 3 under the action of the buffer component.

[0042] Since positioning rods 1 and 2 lack cushioning components, they are made of plastic. The plastic material of positioning rods 1 and 2 minimizes the risk of scratches to the lamp housing.

[0043] Of course, to ensure strength, the positioning rod 2 is made of metal.

[0044] In this embodiment, the sleeve 5 is made of rubber. However, depending on the actual situation, it is also feasible to use fabric covering the positioning rod 3 as the sleeve 5.

[0045] The clamping assembly includes a base 6, a pressure head 7, a handle 8, and a connecting rod 9. The lower part of the base 6 is fixed to the base plate 1. The two ends of the base 6 have protruding hinge portions 6a and 6b, respectively. The lower part of the inner end of the pressure head 7 is hinged to the hinge portion 6a. The inner end of the handle 8 is hinged to the upper part of the inner end of the pressure head 7. The two ends of the connecting rod 9 are hinged to the middle of the handle 8 and the hinge portion 6b, respectively. When an external force is applied to make the outer end of the handle 8 swing down and abut against the hinge portion 6b, a parallelogram structure with four-point hinges is formed between the base 6, the pressure head 7, the handle 8, and the connecting rod 9, and the structure is in a locked state at this time.

[0046] After the base 6, pressure head 7, handle 8, and connecting rod 9 form a parallelogram structure with four-point hinges, the entire clamping assembly can be locked. At this time, the edge of the lamp housing is stably pressed between the pressure head 7 and the base plate 1. Only when the operator applies external force to swing the handle 8 upward can the above-mentioned locking state be released and the pressure head 7 be swung upward. After being swung upward, the pressure head 7 stably detaches from the lamp.

[0047] The connecting part 6c protruding from the side of the base 6 also includes a support rod 10. The upper end of the support rod 10 is fixed to the connecting part 6c, and the lower end of the support rod 10 is fixed to the substrate 1.

[0048] The connecting part 6c provides sufficient space for the support rod 10 to be connected.

[0049] The connecting part 10 has two support rods 10 along its length. Of course, depending on the actual situation, it is feasible to have three or four support rods 10.

[0050] The base 6 has protruding connecting parts 6c on both sides, and each connecting part 6c has several support rods 10.

[0051] Each connecting part 6c has multiple corresponding support rods 10. Therefore, the above structure can ultimately enable the clamping assembly to be stably connected to the substrate 1.

[0052] This lampshade mounting fixture positions the lamp housing on both sides using positioning part one and positioning part three, and on the rear side using positioning part two. Therefore, the lamp housing to be assembled can be directly pushed onto the base plate, and the three positioning parts provide stable positioning. It can be seen that during assembly, only one operator is needed to position the lamp housing between the three positioning parts on the base plate. Because the positioned lamp housing is fixed, subsequent lampshade assembly can proceed smoothly and quickly. Clearly, this lampshade mounting fixture allows one operator to quickly complete the installation of the lampshade for explosion-proof lighting fixtures, saving labor and speeding up the process.

[0053] Meanwhile, the clamping assembly further stabilizes the lamp housing. In other words, the three positioning parts initially position the lamp housing, and the clamping assembly achieves final stable positioning, effectively improving the positioning stability of the lamp housing and ensuring that the lamp housing will not loosen during the installation of the lampshade and the lamp housing, which has high practical value.

[0054] 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.

[0055] The technical solutions in the above embodiments have clearly and completely described the content of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
