Description

Technical Field

[0001] This utility model relates to the field of road signage equipment technology, and in particular to a traffic sign installation and positioning device. Background Technology

[0002] Many subway traffic signs are circular in shape and made of plastic. During installation, adhesive is usually applied to the back before installation. Because the surface of the circular traffic signs is smooth, it is not easy to use auxiliary tools for installation. As a result, workers need to wear gloves and install them by hand. This is not only inconvenient to operate, but also requires multiple people to work together. In addition, the traffic signs are easy to slip off the hands during installation, which may lead to installation failure.

[0003] Therefore, it is necessary to provide a new traffic sign installation and positioning device to solve the above-mentioned technical problems. Utility Model Content

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0023] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0024] Please see Figures 1 to 4 This utility model provides a traffic sign installation and positioning device, which includes an attachment plate 1, a clamping arm 2, and a deflection component 4.

[0025] In the embodiments of this utility model, please refer to Figures 1 to 4 A triangular hand-held bracket 5 is fixedly installed on the attachment plate 1. Multiple clamping arms 2 are installed inside the attachment plate 1, arranged in a ring and radially along the attachment plate 1. A drive disc 3, coaxially arranged and rotatably connected, is also installed inside the attachment plate 1. The drive disc 3 drives the clamping arms 2 to slide radially along the attachment plate 1 and clamp the traffic sign. Specifically:

[0026] The attachment plate 1 has an installation cavity 1a and multiple annularly distributed sliding grooves 1b arranged radially along the attachment plate 1. The sliding grooves 1b are connected to the installation cavity 1a. The drive plate 3 is rotatably installed in the installation cavity 1a and has multiple annularly distributed eccentric cavities 3a. The distance between the eccentric cavities 3a and the center of the drive plate 3 decreases in a clockwise direction along the drive plate 3. The clamping arm 2 is slidably installed in the sliding groove 1b and a guide post 22 is fixedly installed on the clamping arm 2. The guide post 22 is inserted into the corresponding eccentric cavity 3a and slidably connected to the eccentric cavity 3a. The clamping end of the clamping arm 2 is fixedly installed with an abutment plate 21, and the abutment plate 21 and the clamping arm 2 form an L-shaped structure. The abutment plate 21 passes through the through cavity 1c of the attachment plate 1 and extends out of the plate surface of the attachment plate 1 for loading traffic signs.

[0027] It should be noted that: when the operator slides the toothed plate 41 along the sliding rod 43, the toothed plate 41 compresses the spring 44, thereby driving the eccentric cavity 3a on the drive disk 3 to drive the guide post 22 to slide the clamping arm 2 in a direction away from the center radial direction of the drive disk 3. At this time, the inner diameter of the clamping ring structure formed by multiple abutment plates 21 increases until it is larger than the inner diameter of the traffic sign. Then, the traffic sign is placed on the loading surface of the attachment disk 1 and located within the clamping ring structure (the back of the traffic sign is facing up). Then, the toothed plate 41 is released, and thus the toothed plate 41... Under the action of the spring force of the spring 44, the toothed plate 41 is driven to slide along the sliding rod 43. At this time, the toothed plate 41 drives the gear 31 to rotate counterclockwise. Therefore, the eccentric cavity 3a on the drive disk 3 drives the guide post 22 to slide the clamping arm 2 towards the center of the drive disk 3, so that the clamping ring structure composed of multiple abutting plates 21 firmly clamps the traffic sign. Then, the back of the traffic sign is coated with adhesive, and then the staff uses the handheld triangular handheld frame 5 to install the traffic sign on the attachment plate 1 into the traffic sign installation area.

[0028] In this embodiment: the abutment plate 21 passes through the cavity 1c of the attachment plate 1 and extends out of the plate surface of the attachment plate 1 for loading traffic signs. The abutment plate 21 extends out of the plate surface of the attachment plate 1 by 2-5mm, so that the clamping part of the abutment plate 21 extending out of the plate surface for loading traffic signs will not exceed the thickness of the sign, thus avoiding the abutment plate 21 from affecting the installation and attachment of the sign, and ensuring that the back of the sign can be completely attached to the installation area.

[0029] The clamping arm 2 adopts a ring-shaped distribution design. Through the cooperation of the eccentric cavity 3a and the guide post 22, it ensures that the clamping force is evenly distributed and can firmly clamp traffic signs of different sizes.

[0030] Furthermore, a limiting slide block 11 is fixedly installed inside the sliding groove 1b, and a limiting protrusion is fixedly fitted into the inner side wall of the limiting slide block 11. The limiting protrusion is inserted into the groove opened on the side wall of the clamping arm 2 and is slidably connected to the groove, thereby improving the stability of the clamping arm 2 when it slides along the sliding groove 1b.

[0031] In the embodiments of this utility model, please refer to Figures 1 to 4A gear 31 is fixedly mounted on the drive disk 3 and coaxially arranged. A deflection assembly 4 for driving the drive disk 3 to rotate is installed inside the attachment disk 1. The deflection assembly 4 includes a toothed plate 41 that meshes with the gear 31 and a spring 44 for pushing the toothed plate 41 to drive the clamping arm 2 to clamp the traffic sign. The deflection assembly 4 also includes a mounting frame 42, which is fixedly mounted inside the attachment disk 1. Two symmetrically distributed sliding rods 43 are fixedly mounted on the mounting frame 42. The toothed plate 41 is sleeved on the two sliding rods 43 and slidably connected to the sliding rods 43. A spring 44 is sleeved on each sliding rod 43. One end of the spring 44 is fixedly connected to the inner wall of the mounting frame 42, and the other end of the spring 44 is fixedly connected to one end of the toothed plate 41. The toothed plate 41 drives the gear 31 to rotate counterclockwise through the elastic force of the spring 44.

[0032] It should be noted that: through the linkage design of the drive plate 3 and the deflection component 4, the operator only needs to slide the toothed plate 41 to quickly adjust the position of the clamping arm 2 to clamp or release the sign. The elastic force of the spring 44 automatically drives the clamping arm 2 to close, which simplifies the operation steps and significantly improves the installation efficiency.

[0033] The working principle of the traffic sign installation and positioning device provided by this utility model is as follows:

[0034] Because the gear plate 41 drives the gear 31 to rotate counterclockwise through the elastic force of the spring 44, in the initial state, the drive disk 3 deflects counterclockwise to its maximum extent (to the extent that the gear 31 rotates counterclockwise). Figure 1 As an explanation), the guide post 22 drives the clamping arm 2 to slide towards the center of the drive disk 3 through the eccentric cavity 3a on the drive disk 3. At this time, the inner diameter of the clamping ring structure composed of multiple abutment plates 21 is the smallest.

[0035] The operator slides the toothed plate 41 along the sliding rod 43, causing the toothed plate 41 to compress the spring 44. This drives the eccentric cavity 3a on the drive plate 3 to drive the guide post 22 to slide the clamping arm 2 in a radial direction away from the center of the drive plate 3. At this time, the inner diameter of the clamping ring structure formed by multiple abutment plates 21 increases until it is larger than the inner diameter of the traffic sign. The traffic sign is then placed on the loading surface of the attachment plate 1 and located in the clamping ring structure (back of the traffic sign facing up). Then the toothed plate 41 is released, and the toothed plate 41 is driven to slide along the sliding rod 43 under the action of the spring 44. At this time, the toothed plate 41 drives the gear 31 to rotate counterclockwise. Therefore, the eccentric cavity 3a on the drive plate 3 drives the guide post 22 to drive the clamping arm 2 to slide towards the center of the drive plate 3, so that the clamping ring structure formed by multiple abutment plates 21 firmly clamps the traffic sign. Then the back of the traffic sign is coated with adhesive, and the operator uses the handheld triangular handheld frame 5 to install the traffic sign on the attachment plate 1 into the traffic sign installation area.

[0036] After installation, the workers slide the toothed plate 41 along the sliding rod 43, causing the toothed plate 41 to compress the spring 44. This increases the inner diameter of the clamping ring structure formed by the abutment plate 21 and removes the clamping of the traffic sign, thus allowing the traffic sign to be installed quickly.

[0037] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
