Furthermore, the technical features mentioned in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

The embodiment of the utility model discloses lock in middle of rail guard, as shown in fig. 1-5, include: lock seat 1 and spring bolt 2 are equipped with lockhole 11 in the lock seat 1, and one side of spring bolt 2 is equipped with the lock platform 21 with lockhole 11 adaptation, is equipped with first locking surface 111 and second locking surface 112 in the lockhole 11 relatively, is equipped with first butt face 211 and second butt face 212 on the lock platform 21, and first butt face 211 and first locking surface 111 locking cooperation, second butt face 212 and second locking surface 112 locking cooperation.

It should be noted that, a lock platform 21 adapted to the lock hole 11 is disposed on one side of the lock tongue 2, the first abutting surface 211 is in locking fit with the first locking surface 111, and the second abutting surface 212 is in locking fit with the second locking surface 112, so as to provide a middle lock of the guard rail, thereby achieving locking in two directions and preventing shaking.

As shown in fig. 2-5, the lock base 1 is provided with at least one first mounting hole 12, and the bolt 2 is provided with at least one second mounting hole 22. In the specific implementation process, the number of the first mounting holes 12 and the number of the second mounting holes 22 are both set to two, the two first mounting holes 12 are distributed at two opposite ends of the lock base 1, and the two second mounting holes 22 are distributed at two opposite ends of the bolt 2.

As shown in fig. 2-5, the first mounting hole 12 and the second mounting hole 22 may be countersunk holes or other holes capable of realizing fixed mounting. In the implementation, the first mounting hole 12 and the second mounting hole 22 are used for mounting the countersunk head screw 3.

As shown in fig. 2-5, the lock platform 21 and the bolt 2 are integrally formed.

As shown in fig. 2 to 5, the width of the lock hole 11 gradually decreases from outside to inside, and the width of the lock platform 21 gradually decreases along a direction away from the lock tongue 2. It should be noted that, because the width of the lock hole 11 gradually decreases from outside to inside, the width of the lock platform 21 gradually decreases along the direction away from the bolt 2, and the greater the depth of the lock platform 21 entering the lock hole 11, the greater the locking degree between the lock platform 21 and the lock hole 11.

As shown in fig. 2-5, the first locking surface 111 and/or the second locking surface 112 are disposed in an arc shape.

As shown in fig. 2 and 3, the first abutting surface 211 and/or the second abutting surface 212 are provided as arc-shaped surfaces.

As shown in fig. 2 and 3, at least one second mounting hole 22 is offset to one side along a center line in a width direction of the locking bolt 2. It should be noted that the second mounting hole 22 is offset to one side along the center line of the bolt 2 in the width direction, and is suitable for mounting a guard rail profile.

As shown in fig. 1-5, the overlapping surfaces of the notches at the two ends of the lock base 1 and the lock tongue 2 are T-shaped surfaces or rectangular surfaces. It should be noted that, because the notch faying surface at lock base 1 and spring bolt 2 both ends is T profile or rectangular surface, conveniently carries out preassembly, and the adaptation section bar notch, the installation is stable does not produce and rocks.

As shown in fig. 6 and 7, the lock base 1 is fixedly mounted on the sash profile 4 by a countersunk screw 3, and the latch bolt 2 is fixedly mounted on the frame profile 5 by a countersunk screw 3. It should be noted that, as the lock base 21 is inserted into the lock hole 11, the first abutting surface 211 is in locking fit with the first locking surface 111, and the second abutting surface 212 is in locking fit with the second locking surface 112, so that the bolt 2 and the lock base 1 are locked in two directions, and the sash section 4 and the frame section 5 can be prevented from shaking.

The working principle is as follows: one side of the bolt 2 is provided with a lock platform 21 matched with the lock hole 11, the first abutting surface 211 is in locking fit with the first locking surface 111, and the second abutting surface 212 is in locking fit with the second locking surface 112, so that a guard rail middle lock is provided, locking in double directions is realized, and shaking is prevented.

It should be understood that the above examples are only for clarity of illustration and are not intended to limit the embodiments. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. And obvious variations or modifications can be made without departing from the scope of the invention.
