Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1 and 2, the present invention provides a fixing and locking device with a sliding block, which includes a fixing base 1, an upper cover 2, a sliding block 3, a spring 4 and a set screw 5. The upper surface of the fixed base 1 is provided with a sliding chute 11 with two ends not penetrating through along the long edge direction; the upper cover 2 is fixedly connected to the upper surface of the fixing base 1 through a bolt 6, the upper cover 2 is provided with a threaded hole 21 and an equipment mounting hole 22, the equipment mounting hole 22 is also a threaded hole, and after the fixing and locking device is fixed on a lamp post, the external functional module can be mounted through the bolt. The number of the sliding blocks 3 is two, the sliding blocks are arranged in the sliding groove 11 side by side and can slide along the direction of the sliding groove 11. Referring to fig. 3, the fixing and locking device is a bilateral structure. The inner sides (the sides in contact with each other) of the sliding blocks are provided with inclined planes 31, the inclined planes of the two sliding blocks are close to each other to form a V-shaped groove right below the threaded hole 21, the outer sides of the sliding blocks are respectively provided with a convex block 32, and the convex blocks 32 extend out of the fixed base 1 along with the outward movement of the sliding blocks 3. In the extended state, the protrusions 32 on both sides abut against the inside of the T-shaped groove of the lamp post, so that the fixing and locking device cannot freely slide in the T-shaped groove, and the fixing of the fixing and locking device is realized.

Referring to fig. 3, in a normal state, the two sliders 3 are close to each other toward the middle, and the protrusion 32 is hidden in the fixed base. To achieve this effect, a spring 4 is mounted on the outside of each slider 3. Specifically, the first end of the spring 4 is installed on the outer side of the sliding block 3, and the second end is installed on the inner side of the fixed base 1. The spring 4 is a compression spring and pushes the slider 3 inward. In order to extend the projection 32, the jack screw 5 is installed in the screw hole 21, and as the jack screw 5 is gradually screwed into the screw hole 21, the lower end of the jack screw 5 contacts the inclined surface 31 of the slider to push the slider 3 and the projection 32 outward, so that the projection 32 protrudes out of the fixing base.

It is worth mentioning that in order to prevent the damage of the workpiece caused by the process that the lower end of the jacking screw 5 is extruded with the inclined plane 31, the lower end of the jacking screw 5 is provided with a chamfer, the formed chamfer surface is attached to the inclined planes 31 of the two sliders, and in the process of screwing the jacking screw 5, the original line contact is changed into surface contact, so that the contact area is increased, the pressure is reduced, and the damage of the workpiece is reduced to the greatest extent.

In the present embodiment, referring to fig. 3, in order to enhance the stability of the installation of the spring 4, a first groove 33 is disposed at a contact position of the slider 3 and the spring 4. Similarly, a second groove 12 is arranged at the contact position of the fixed base 1 and the spring 4. In fig. 3, the right-hand spring 4 is omitted for the sake of clarity in the illustration of the first recess 33 and the second recess 12. The two ends of the spring 4 are respectively positioned in the first groove 33 and the second groove 12, the two ends of the spring do not need to be welded, and the mounting stability is also guaranteed.

In order to more conveniently install the spring, the bottom of the second groove 12 is provided with a hole sealing screw 13. In the installation process, the spring is firstly placed into the first groove 33 from the through hole of the fixed base, and then the hole sealing screw 13 is screwed into the through hole to resist the outer end of the spring 4.

Referring to fig. 2, in order to deepen the device mounting hole 22, the device mounting hole 22 extends downward into the stationary base 1.

In the specific installation process, the fixing and locking device is firstly placed into the T-shaped groove 71 of the lamp post 7 along the short edge, and then the fixing and locking device body is rotated, as shown in fig. 4, so that the long edge of the fixing and locking device body is clamped in the T-shaped groove 71. As shown in fig. 5, the set screw is then screwed into the threaded hole to tighten the projections on both sides against the inner wall of the T-shaped groove 71, thereby limiting the sliding of the fixed locking device in the T-shaped groove. Finally, as shown in fig. 6, the functional module 8 is fixed in the device mounting hole of the upper cover 2 by a bolt. The whole process does not need to be perforated on the original lamp pole, and the lamp pole is not damaged.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
