Description

Technical Field

[0001] This utility model relates to the field of civil defense door processing, and in particular to a drilling and positioning fixture for civil defense doors. Background Technology

[0002] Civil defense doors are used as entrances and exits for civil defense projects. They are manufactured in accordance with national civil defense standards and are mainly made of metal. During the manufacturing process, larger metal parts are quite heavy. The drilling operation is mostly done manually and requires strict control of drilling accuracy. This requires workers to measure and confirm the drilling position multiple times before drilling. However, during the measurement process, operators often forget to mark the position after measurement, and the markings are not obvious, making it difficult to find the drilling position. This requires re-measurement and confirmation of the position. Therefore, the whole process is inefficient and prone to quality problems. Utility Model Content

[0003] One objective of this utility model is to provide a hole-drilling and positioning fixture for air-raid shelter doors that at least solves any of the above-mentioned technical problems.

[0004] A further objective of this invention is to avoid workers having to measure and confirm the drilling location multiple times, thereby preventing situations where the marking is forgotten after the measurement is completed.

[0005] Another further objective of this invention is to improve the drilling effect and fix the drilling position.

[0006] In particular, this utility model provides a hole-drilling and positioning clamp for a civil defense door, including a first clamping member. The first clamping member has a right corner placed on the door body, and a through groove is provided on the upper part of the first clamping member, and a sliding plate is provided in the groove.

[0007] A second clamping member, one end of which is telescopically connected to the first clamping member, and a portion of the second clamping member is located on the opposite side of the first clamping member.

[0008] Furthermore, a positioning element is provided at one end of the sliding plate near the door.

[0009] Furthermore, a positioning hole is provided in the middle of the positioning member.

[0010] Furthermore, both the first clamping member and the second clamping member have a plurality of rollers on the side facing the door body, and the rollers are partially embedded in the first clamping member and the second clamping member.

[0011] Furthermore, the first clamping member has a telescopic groove at one end facing the second clamping member, the second clamping member is inserted into the telescopic groove at one end facing the first clamping member, and the first clamping member is provided with a fixing screw inserted into the telescopic groove.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] This utility model forms a door clamping structure by arranging the first and second clamping parts of the positioning fixture vertically. In use, the first and second clamping parts are first installed and clamped on one side of the door, the distance between the first and second clamping parts and the upper and lower surfaces of the door is tightened, and the fixing screws are tightened. Then, the first and second clamping parts are moved to the same horizontal line as the position where a hole needs to be drilled. At the same time, the positioning hole on the sliding plate is moved to align with the position where a hole needs to be drilled. Then, the drill bit is passed through the positioning hole to drill a hole, accurately aligning the drilling position. It is convenient to use and has a good positioning effect.

[0023] This embodiment provides a drilling and positioning fixture for a civil defense door, including a first clamping member 301 and a second clamping member 302. The first clamping member 301 has a right-hand corner placed on the door body 1, and a through groove 3011 is provided on the upper part of the first clamping member 301, in which a sliding plate 303 is disposed. One end of the second clamping member 302 is telescopically connected to the first clamping member 301, and a portion of the second clamping member 302 is located on the opposite side of the first clamping member 301. Figures 1 to 5 As shown, the door 1 is laid flat, and a support block is placed under the door panel. The drilling and positioning clamp 3 is clamped and fixed from one side of the door 1. By setting a roller 306 on the side facing the door 1, the positioning clamp 3 can be moved according to different drilling point positions.

[0024] It should be further explained that a positioning member 304 is provided at one end of the sliding plate 303 near the door body 1. The positioning member 304 is fixedly connected to the sliding plate 303. A positioning hole 3041 is provided in the middle of the positioning member 304. The positioning hole 3041 can be aligned with the drilling position, so that the drill bit is kept perpendicular to the door body 1, preventing the drilling position or hole from being off-center.
