[0015] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. 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.
[0016] A protective device for construction, such as Figure 1 , 2 As shown in Figures 3, 4, and 5, the device includes a base 1, on which a barrier 2 is movably mounted. A first dovetail slider 3 is fixedly installed at the bottom of the barrier 2. Several first dovetail grooves 4 are formed on the top of the base 1 corresponding to the first dovetail slider 3. In this embodiment, there are three first dovetail grooves 4, with their front and rear ends communicating with the outside. The first dovetail slider 3 can be slidably installed within the first dovetail slider 4. The barrier 2 consists of three parts: front, middle, and rear. The first dovetail slider 3 is also divided into three parts corresponding to the barrier 2. One side of two adjacent parts of the barrier 2 is rotatably connected by a vertical hinge axis. The front-to-back length of the middle part of the barrier 2 is greater than or equal to the sum of the front-to-back lengths of the front and rear parts of the barrier 2. This utility model has a simple structure and ingenious design. The barrier 2 can be folded up, and its length after folding is less than a person's arm span, making it easy to transport and store. It meets market demand and is suitable for promotion. When using this utility model, the base 1 is fixedly installed in a suitable position on the ground, and the first dovetail slider 3 on the enclosure 2 is slidably installed in one of the first dovetail grooves 4, thereby installing the enclosure 2 on the base 1. The user can select any first dovetail groove 4 according to actual needs. After use, the enclosure 2 is moved, and the movement of the enclosure 2 causes the first dovetail slider 3 to move out of the first dovetail groove 4. The front part of the enclosure 2 is rotated 180 degrees backward along the hinge axis between the front part and the middle part, and the rear part of the enclosure 2 is rotated 180 degrees forward along the hinge axis between the rear part and the middle part, thereby folding the enclosure 2 up for easy handling and storage. Then the base 1 is removed from the ground for easy use next time.
[0017] Specifically, as shown in the figure, the bottom of the enclosure 2 in this embodiment has a groove 20, the front side of which is connected to the outside. The first dovetail slider 3 has a corresponding insertion hole 21 on the groove 20, and the inner wall of the first dovetail slide 4 has a corresponding slot 22 on the insertion hole 21. The groove 20, the insertion hole 21 and the slot 22 aligned with the insertion hole 21 are coaxially arranged and connected. The insertion rod 23 is slidably installed on the inner circumference of the insertion hole 21. The insertion rod 23 is connected to the first dovetail slider 3 through a spring 24. The spring 24 is fitted on the outer circumference of the insertion rod 23. One end of the spring 24 is fixedly connected to the outer circumference of the insertion rod 23, and the other end of the spring 24 is fixedly connected to one side of the first dovetail slider 3. The upper end of the insertion rod 23 is located in the groove 20, and a person's finger can be inserted into the groove 20 to pull the insertion rod 23 upward. The lower end of the insertion rod 23 is inserted into the aligned slot 22. Pulling the insert rod 23 upwards causes the spring 24 to extend, retracting the lower end of the insert rod 23 into the insertion hole 21. This allows the first dovetail slider 3 to slide into one of the first dovetail grooves 4. Then, releasing the insert rod 23 causes it to align with the slot 22. Under the elastic force of the spring 24, the insert rod 23 moves downwards to engage with the slot 22, thus limiting the first dovetail slider 3 and the enclosure 2 and preventing them from sliding back and forth. Similarly, pulling the insert rod 23 upwards retracts it into the insertion hole 21, allowing the first dovetail slider 3 to slide back and forth.
[0018] Specifically, as shown in the figure, a baffle 30 is fixedly installed at the upper end of the insertion rod 23 in this embodiment. Pulling the insertion rod 23 through the baffle 30 is more convenient and less strenuous.
[0019] Furthermore, as shown in the figure, the base 1 described in this embodiment has several mounting holes 40. The mounting holes 40 facilitate the fixing of the base 1 to a designated position on the ground.
[0020] Furthermore, as shown in the figure, vertical second dovetail sliders 50 are fixedly installed on the sides of the front, middle, and rear sections of the enclosure 2 away from the hinge axis, respectively. The structural strength of the enclosure 2 can be increased by using several second dovetail sliders 50.
[0021] Furthermore, as shown in the figure, in this embodiment, the bottom of the base 1 has two second dovetail slide grooves 60 corresponding to the two second dovetail sliders 50 of the front and rear parts of the enclosure 2. By rotating the front and rear parts of the enclosure 2 along the hinge axis to fold the enclosure 2, the second dovetail slider 50 of the middle part of the enclosure 2 is slidably installed in the first dovetail slide groove 4 in the middle of the base 1, and the second dovetail sliders 50 on the front and rear parts of the enclosure 2 are slidably installed in the second dovetail slide groove 60 at the bottom of another base 1. The two bases 1 and the folded enclosure 2 are spliced together, which is convenient for transportation and can be further spliced with the enclosure 2 and the base 1 as needed.
[0022] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
