Description

Technical Field

[0001] The utility model provides a roadblock with stable placement for municipal engineering construction, belonging to the technical field of municipal construction tools. Background Technique

[0002] In municipal engineering construction, in order to ensure the safety of the construction area, prevent non-construction personnel from entering the construction site and guarantee traffic safety during the construction process, various types of roadblocks usually need to be set up. These roadblocks can effectively guide the traffic flow, protect construction personnel and equipment, and prevent accidents. Especially in urban roads and busy traffic areas, the use of roadblocks for municipal engineering construction is particularly important.

[0003] At present, there are various types of roadblocks for municipal engineering construction, including plastic conical roadblocks, rubber roadblocks, steel roadblocks, etc. Among them, plastic conical roadblocks are widely used in municipal engineering sites due to their light weight, easy handling and economic characteristics. The traditional plastic conical roadblock design is usually made of integrally formed plastic materials, with certain flexibility and a significantly marked function in color. However, the existing plastic conical roadblocks have obvious deficiencies in terms of stability. Due to the relatively light weight of the plastic material itself and the conical structure design, they are prone to tipping or displacement when affected by strong winds or vehicle impacts. Therefore, in some special occasions of the existing technology, in order to ensure the stability of the plastic conical roadblocks, weights are usually added to the roadblocks; however, when installing the weights, fixing components such as screws are often required to fixedly connect the weights to the bottom of the roadblocks, resulting in low installation efficiency and inconvenient adjustment of the weight of the weights. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is the insufficient stability of the traditional plastic conical roadblock, low efficiency in assembling weights, and inconvenient adjustment of the weight of the weights.

[0005] In order to solve the above problems, the technical solution proposed by the utility model is: a roadblock with stable placement for municipal engineering construction, including a conical cylinder; a bottom plate is arranged below the conical cylinder; an installation groove is opened in the bottom plate, and an installation plate inserted into the installation groove is fixedly connected below the conical cylinder; fixing holes are opened on the outer wall of the installation plate, and an elastic plugging component inserted into the fixing holes is arranged in the bottom plate; a bottom groove located inside the conical cylinder is opened on the upper surface of the bottom plate, and a weight block installed on the bottom plate through the bottom groove is arranged inside the conical cylinder; the weight block is frustum-shaped, the weight blocks are stacked up and down inside the conical cylinder, and the inclined surface of the weight block is mutually attached and corresponding to the inclined surface of the inner wall of the conical cylinder.

[0006] As an improvement, the installation plate is circular, and the fixing holes are evenly distributed in a circular pattern on the installation plate.

[0007] As an improvement, the elastic plug-in component includes a fixing rod, a fixing plate, and a compression spring. A groove is formed in the bottom plate, the fixing rod is located in the groove, and the fixing rod is inserted into the fixing hole; the fixing plate is fixedly sleeved on the fixing rod, and the compression spring is sleeved on the fixing rod.

[0008] As an improvement, a compression amount is reserved when the compression spring is installed; a countersunk hole is formed in the side wall of the bottom plate, and the operating end of the fixing rod is located in the countersunk hole.

[0009] As an improvement, a connecting block is fixedly connected to the lower end of the counterweight block, and a connecting groove is formed in the upper end of the counterweight block; the connecting block of the counterweight block located above is inserted into the connecting groove of the counterweight block located below, and the connecting block of the lowermost counterweight block is inserted into the bottom groove.

[0010] The beneficial effects of the present utility model:

[0011] Fixing holes are formed in the outer wall of the mounting plate, and an elastic plug-in component inserted into the fixing holes is arranged in the bottom plate; by providing the fixing holes and the elastic plug-in component, the quick connection of the conical cylinder and the bottom plate can be facilitated. The counterweight blocks are stacked on the bottom plate, and the mass of the counterweight is changed by the stacking quantity. At the same time, the lowermost counterweight block does not need to be fixed to the bottom plate, and the counterweight blocks do not need to be fixed to each other either. Only by utilizing the cooperation between the inclined surface of the frustum-shaped counterweight block and the inclined surface of the inner wall of the conical cylinder, the counterweight blocks can stay stably in the conical cylinder, and the installation efficiency of the roadblock can be improved.

[0019] By setting the elastic plugging component, the assembly of the bottom plate 1 and the conical cylinder 2 can be quickly completed, and the counterweights 7 are stacked up and down on the bottom plate 1. By changing the number of counterweights 7, the mass of the counterweight can be changed, and the cooperation between the inclined surface of the inner wall of the conical cylinder 2 and the frustum-shaped counterweight 7 can stably fix and limit the counterweight 7 inside the conical cylinder 2, without additionally fixing the counterweight 7, improving the assembly efficiency.

[0020] As Figure 2 shown, the installation plate 4 is circular, and the fixing holes 5 are evenly distributed in a circular pattern on the installation plate 4. The setting of multiple fixing holes 5 can reduce the time for aligning the fixing holes 5 with the fixing rods 6 when installing the conical cylinder 2, and even if the installation plate 4 is not accurately aligned when inserted into the installation groove 3, the fixing rods 6 can be inserted into the fixing holes 5 by slightly rotating the conical cylinder 2.

[0021] As Figure 4 shown, the elastic plugging component includes fixing rods 6, fixing plates 10, and compression springs 11. Grooves 9 are opened in the bottom plate 1, the fixing rods 6 are located in the grooves 9, and the fixing rods 6 are inserted into the fixing holes 5; the fixing plates 10 are fixedly sleeved on the fixing rods 6, and the compression springs 11 are sleeved on the fixing rods 6. The compression springs 11 have a reserved compression amount during installation, which can continuously generate pressure on the fixing plates 10, thereby increasing the stability of the fixing rods 6 in fixing the installation plate 4; counterbored holes 8 are opened on the side wall of the bottom plate 1, and the operating ends of the fixing rods 6 are located in the counterbored holes 8. The setting of the counterbored holes 8 can prevent the fixing rods 6 from being accidentally touched.

[0022] A connecting block 12 is fixedly connected to the lower end of the counterweight block 7, and a connecting groove 13 is formed in the upper end of the counterweight block 7; the connecting block 12 of the counterweight block 7 located above is inserted into the connecting groove 13 of the counterweight block 7 located below, and the connecting block 12 of the lowermost counterweight block 7 is inserted into the bottom groove 14; the counterweight block 7 is connected to the bottom plate 1 through the bottom groove 14, and the counterweight block 7 is connected to the counterweight block 7 through the connecting block 12 and the connecting groove 13, which can quickly position the counterweight block 7 when installing the counterweight block 7.

[0023] Principle of the utility model

[0024] As Figure 5 shown, when assembling the counterweight for the roadblock, first select the appropriate number of counterweight blocks 7 according to actual needs, stack the counterweight blocks 7 on top of the bottom plate 1 in sequence through the bottom groove 14, the connecting block 12 and the connecting groove 13. After the state shown in Figure 2 is achieved, then install the conical cylinder 2. Pull the fixing rod 6 to make the fixing rod 6 retract into the groove 9, and at the same time, the fixing plate 10 compresses the compression spring 11; insert the mounting plate 4 below the conical cylinder 2 into the mounting groove 3 to align the fixing hole 5 with the fixing rod 6, and release the fixing rod 6. Under the action of the resilience of the compression spring 11, the fixing rod 6 is inserted into the fixing hole 5, thereby quickly fixing and connecting the bottom plate 1 and the conical cylinder 2, as Figure 4 shown. When the bottom plate 1 and the conical cylinder 2 are fixedly connected, the inclined surface of the frustum-shaped counterweight block 7 is in mutual contact with the inclined surface of the inner wall of the conical cylinder 2. Without fixedly connecting the counterweight blocks 7 to each other, the stacked counterweight blocks 7 can be stably limited and fixed in the conical cylinder 2, as Figure 3 shown.

[0025] The above describes the utility model and its implementation manners. This description is not restrictive. What is shown in the drawings is only one of the implementation manners of the utility model, and the actual structure is not limited thereto. Generally speaking, if those of ordinary skill in the art are inspired by it and design similar structural manners and embodiments without creative work without departing from the creative purpose of the utility model, they shall fall within the protection scope of the utility model.
