Description

Technical Field

[0001] The utility model relates to the field of airport pavement and municipal road construction, in particular to a lightweight Beckmann beam wind shielding device. Background Art

[0002] During the construction process, the applicant found that the Beckman beam was affected by wind during the inspection process, which made it difficult to ensure the accuracy of the inspection data. The inspection process was time-consuming and labor-intensive. Through research and development, a number of Beckman beam wind shielding devices were developed and patents were applied for: a Beckman beam wind shielding device (application number 2024201774140), a folding Beckman beam wind shielding board (application number 2024201922689). During use, it was found that both were too heavy and required two people to lift. Although a folding Beckman beam wind shielding board overcomes the disadvantage of a Beckman beam wind shielding device that is inconvenient to store, its length is too long. In order to prevent deformation, it cannot be placed vertically and can only be placed horizontally, so the disadvantage of inconvenient storage is still not completely solved. Utility Model Content

[0003] The utility model aims to solve the problems existing in the above-mentioned prior art and provide a lightweight Beckmann beam windshield device which is light in weight and convenient to store.

[0004] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a lightweight Beckman beam windshield device, the main points of which are: it includes a support rod, a foldable windshield cloth and a plurality of pressure strips, the support rod is an inverted "V" shape, and the bottom is a straight rod extending to both sides, and the plurality of support rods are fixed at equal intervals on the inner surface of the foldable windshield cloth, and the pressure strip is provided with fixing holes.

[0005] The utility model uses a lightweight foldable windshield cloth to replace the original aluminum alloy plate, which reduces the overall weight, uses support rods as a skeleton to meet the overall rigidity and strength, and uses pressure strips to ensure the overall stability. The design of multiple pressure strips also overcomes the length problem of accessories.

[0006] The bottom edge of the foldable windshield has a hole that matches the fixing hole of the pressure strip, and the circumference of the hole has a fixing ring to prevent cracking, and below the fixing hole there is a circle of countersunk holes that match the outer circle of the fixing ring. The pressure strip can press the foldable windshield flat by the cooperation between the countersunk holes and the fixing ring.

[0007] The width of the layering strip is equal to the length of the straight rod of the support rod.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. This description is only a preferred embodiment of the utility model and is not intended to limit the protection scope of the utility model. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] like Figure 1 As shown, a lightweight Beckman beam windshield device includes a support rod 1, a foldable windshield cloth 2 and a pressure strip 3. The support rod 1 is inverted "V" shape, with a straight rod 101 extending to both sides at the bottom. A plurality of support rods 1 are fixed on the inner surface of the foldable windshield cloth 2 at equal intervals. The fixing method of the support rod can refer to the fixing method of the ribs of an umbrella, and can also be made of two layers of cloth sewn into a fixed through hole. The pressure strip 3 is provided with a fixing hole 301. The support rod is bent from a steel bar (rust-free) with a diameter of 0.5 mm, or connected by four sections of support rods. The connecting part has the same structure as the ribs of an umbrella, and is hinged between two of them. The distance between two adjacent support rods 1 is 30-60 cm.

[0023] An unfolded width limiting module 5 is arranged between the two windshield modules. The unfolded width limiting module 5 is two straight bars hinged to each other. The free ends of the straight bars are hinged and fixed to the two windshield modules 1 respectively. When retracted, the width limiting module is sealed and does not affect the overall thickness. When opened, the width limiting module is unfolded, but its overall length is fixed, so it also limits the width between the two windshield modules after unfolding. After opening, it can be used directly without adjusting the opening angle. When there is an unfolded width limiting module, the support rods at both ends can also be replaced with end face fixing strips, that is, there are end face fixing strips on both end faces. The end face fixing strips are made of flat steel, and the folding method is similar to the support rod. The width is 3-10mm, which is convenient for fixing the unfolded width limiting module 5. Using the end face fixing strip 7 to fix the unfolded width limiting module can ensure that the connection between the two is more firm.

[0024] The bottom edge of the foldable windshield cloth 2 has a hole corresponding to the pressure strip fixing hole 301, and the circumference of the hole has a fixing ring to prevent cracking. The inner diameter of the fixing ring is not less than the inner diameter of the fixing hole 301. The pressure strip has a circle of countersunk holes below the fixing hole 301 that match the outer circle of the fixing ring.

[0025] The width of the layering strip 3 is equal to the length of the support rod straight rod 101. The length of the layering strip is generally about 40-50 cm, and it is composed of multiple strips. In this example, it is composed of four equal-length sections, a total of eight strips on the left and right, which can be used universally.

[0026] There is a marking line 201 on the side of the foldable windshield cloth 2 corresponding to the fixing circle. The fixing position between the convenient pressing strip and the foldable windshield cloth corresponds.

[0027] A binding belt 4 is fixed on the outer surface of the foldable windshield 2, and the two ends of the binding belt 4 have matching snap buckles, and there are also snap buckles matching the snap buckles at the corresponding positions on the outer surface of the foldable windshield 2. The utility model has its own binding belt, which is used to tie up when stored, and is fixed to the snap buckles on the surface of the foldable windshield when working.

[0028] The foldable windshield is provided with a longitudinal through hole in the middle of the foldable windshield, which is used to pass a telescopic rod or a steel wire, such as a foldable flat telescopic rod. A telescopic rod 6 having the same longitudinal length as the foldable windshield is provided, and a telescopic rod end fixing sleeve 601 larger than the through hole is provided at one end to facilitate taking out the telescopic rod.

[0029] Or there is a steel wire that is consistent with the longitudinal length of the foldable windshield.

[0030] The utility model utilizes a telescopic rod or a steel wire as a longitudinal support of the top of the foldable windshield cloth, which is inserted when in use to ensure the rigidity of the top of the foldable windshield cloth, and can be stored by folding or winding when not in use.

[0031] The remaining parts not described are the same as the prior art.

[0032] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
