Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings 1 to 6 and the specific embodiments.

The doorframe installing tool as shown in fig. 1 comprises a telescopic supporting rod 10 and two clamping pieces 20 respectively arranged at opposite ends of the telescopic supporting rod 10. The telescopic support rod 10 is used for adjusting the distance between the clamping pieces 20 at the two ends, the clamping pieces 20 are used for clamping and fixing on the door frame upright post, and the two clamping pieces 20 are matched with each other to limit the relative position of the door frame upright post, in particular to enable the centers of the two upright posts of the door frame to be positioned on the same vertical plane. When a plurality of door frame mounting tools are used for mounting the same door frame, the door frame mounting tools can be arranged at intervals in the height direction of the door frame, the telescopic supporting rods 10 of each door frame mounting tool are kept at the same length, the upper part and the lower part of the door frame upright post are both in a vertical state, the clearance sizes of the upper part and the lower part of the door frame upright post are consistent, the relative position of the door frame upright post is controlled, and the deformation of the door frame or the uneven upper and lower gaps in the construction process are avoided.

As shown in fig. 2 and 3, each clamping member 20 of the present embodiment includes a fixed clamping head, a movable clamping head, and a locking mechanism, the fixed clamping head is provided with a fixed clamping end, the movable clamping head is provided with a movable clamping end, the fixed clamping end and the movable clamping end are arranged at a relative distance to form a clamping space, the fixed clamping head is further provided with a limiting groove 24, and the movable clamping head passes through the limiting groove 24 and is in relative sliding fit with the fixed clamping head to enable the movable clamping end to approach or leave the fixed clamping end; the locking mechanism is matched with the fixed chuck and the movable chuck to realize the locking or unlocking of the movable chuck and the fixed chuck.

As shown in fig. 4, the fixed collet includes a web 21 and first and

second end plates

22 and 23 respectively disposed at opposite ends of the web 21; the web plate 21 is connected with the telescopic support rod 10, the first end plate 22 is provided with a fixed clamping end right facing the surface of the second end plate 23, and the second end plate 23 is provided with a limiting groove 24.

As shown in fig. 5, the movable chuck includes a back plate 25 and a third end plate 26, the back plate 25 passes through the limiting groove 24, one end of the back plate 25 is provided with the third end plate 26, the third end plate 26 is located between the first end plate 22 and the second end plate 23, and the face of the third end plate 26 facing the first end plate 22 is provided with the movable chuck. The web 21 and the back plate 25 are parallel. The limiting groove 24 limits the moving direction of the back plate 25, so that the back plate 25 can only move parallel to the web 21 to realize that the movable clamping end is close to or far away from the fixed clamping end. When a clamping piece 20 is used for clamping a stand column of a door frame, the relative position of the back plate 25 and the limiting groove 24 is adjusted to reserve a clamping space, the stand column to be clamped of the door frame is positioned in the clamping space, the back plate 25 is pushed, and the movable clamping end is close to the fixed clamping end until the movable clamping end and the fixed clamping end are respectively clamped on two sides of the stand column. In the same way, the other clamping member 20 is clamped to the other pillar of the door frame. Since the two clamping members 20 are connected by the telescopic support rod 10, the door frame pillar clamped by the two clamping members 20 is restricted in relative position. Of course, a locking mechanism is required to lock the movable and fixed clamp ends of clamp 20.

As shown in fig. 2 in particular, the locking mechanism includes a first through slot 27, a second through slot 28, a third through slot 29, a first wedge plate 210, and a second wedge plate 211; the first through groove 27 is arranged on the web 21, the second through groove 28 is arranged on the back plate 25, the third through groove 29 is arranged on the first wedge-shaped plate 210, and the small end of the first wedge-shaped plate 210 sequentially penetrates through the second through groove 28 and the first through groove 27, so that the first wedge-shaped plate 210 is in insertion fit with the web 21 and the back plate 25; the small end of the second wedge-shaped plate 211 passes through the third through groove 29 at the small end of the first wedge-shaped plate 210, so that the second wedge-shaped plate 211 is in insertion fit with the first wedge-shaped plate 210.

The first wedge plate 210 and the second wedge plate 211 are triangular plates.

The first wedge plate 210 in this embodiment perpendicularly intersects the second wedge plate 211. The first wedge plate 210 perpendicularly intersects the web 21 and the back plate 25. The slot length direction of the third through slot 29 on the first wedge plate 210 is perpendicular to the web 21 and the back plate 25.

After the movable clamping end and the fixed clamping end clamp the door frame pillar, the first through groove 27 corresponds to the second through groove 28, so that the small head end of the first wedge plate 210 sequentially passes through the second through groove 28 and the first through groove 27, it should be noted that the size of the large head end of the first wedge plate 210 is larger than the size of the first through groove 27 and the second through groove 28, so as to avoid the first wedge plate 210 from being separated from the first through groove 27 or the second through groove 28, and therefore, after the small head end of the first wedge plate 210 passes through the second through groove 28 and the first through groove 27, the small head end and the large head end of the first wedge plate 210 are respectively located on the opposite sides of the back plate 25 and the web plate 21. Then, the second wedge-shaped plate 211 is inserted into the third through groove 29 of the first wedge-shaped plate 210 close to the small end, and the second wedge-shaped plate 211 is matched with the large end of the first wedge-shaped plate 210 to limit the movement of the first wedge-shaped plate 210, so that the web 21 and the back plate 25 are fixed, and the movable clamping end and the fixed clamping end are kept in a clamping state. In this state, the second wedge plate 211 may abut on the surface of the web 21 opposite to the back plate 25 to further clamp the web 21 and the back plate 25.

In order to facilitate the cooperation of the first wedge plate 210 with the second through grooves 28 and the first through grooves 27, as shown in fig. 4, the first through grooves 27 are plural, and the plural first through grooves 27 are arranged in an array on the web 21. The plurality of first through grooves 27 arranged on the web 21 in an array comprise a plurality of first groove groups arranged at intervals in the width direction of the web 21, each first groove group comprises a plurality of first through grooves 27 arranged at intervals in the length direction of the web 21, and the first through grooves 27 of adjacent first groove groups are arranged at intervals in the width direction of the web 21.

Referring to fig. 5, the second through groove 28 is provided in plural, and the plural second through grooves 28 are arranged in an array on the back plate 25.

Through the arrangement of the plurality of first through grooves 27 and the plurality of second through grooves 28, the position where the first wedge plate 210 is inserted is more flexibly selected, and thus the clamping accuracy of the clamping member 20 is higher.

As shown in fig. 6, the telescopic supporting rod 10 includes a holder 11 and rod bodies 12 respectively disposed at both ends of the holder 11, and the holder 11 includes an internally threaded tube. One end of the rod body 12 is in threaded fit with the internal threaded pipe, and the other end of the rod body 12 is connected with the fixed chuck.
