Description

Technical Field

[0001] The utility model belongs to the technical field of proximity switch accessories and relates to an elastic telescopic bracket for a proximity switch. Background Art

[0002] Proximity switches are devices commonly used in engineering to transmit equipment working signals. When a device approaches the sensing distance of the proximity switch, it triggers its internal controller and sends a signal to the outside, and stops sending signals when the device is out of the sensing distance. This function of the electronic component is often used in engineering practice to determine whether the equipment is in operation. However, considering the operation mode, operation distance and harsh working environment of the equipment, the equipment cannot directly approach the proximity switch or cannot run within its sensing distance when it directly approaches the proximity switch, or may damage the proximity switch when it runs within the sensing distance. At the same time, proximity switches with long sensing distances are often more expensive, increasing the cost of use and maintenance. Utility Model Content

When the load contacts the load baffle 1, the load baffle 1 will overcome the elastic force of the elastic support structure, so that the signal baffle 3 gradually approaches the proximity switch 5 mounted on the proximity switch mounting frame 4, so that the proximity switch 5 sends the working state of the load in the form of an electrical signal.

[0025] In the utility model, the relative movement between the proximity switch and the load is vertical movement, which avoids the possibility of damaging the proximity switch due to direct contact between the load and the proximity switch, and solves the problem that the proximity switch is easily damaged.

[0026] In order to improve the adaptability of the bracket, the present invention sets the position of the signal baffle 3 to be adjustable, that is, along the axial direction of the proximity switch, the position of the signal baffle 3 relative to the load baffle 1 is adjustable. The signal baffle 3 can be of the following structure: a slide rail and slider structure is provided between the signal baffle 3 and the load baffle 1 to achieve relative movement between the two, and the two are locked by a locking structure, which can be a locking screw.

[0027] In order to facilitate the adjustment of the sensing area of ​​the proximity switch 5, the utility model designs the proximity switch mounting frame 4 as an adjustable structure, that is, the proximity switch mounting frame 4 can make the position of the proximity switch 5 in the axial direction and vertical direction of the proximity switch adjustable. The proximity switch mounting frame 4 can be the following structure: the proximity switch mounting frame 4 includes a guide rail located on the bracket bottom plate 6 and arranged parallel to the axial direction of the proximity switch, a slider slidably connected to the guide rail, and a mounting plate arranged on the slider, and the mounting plate is provided with a strip mounting groove for mounting the proximity switch 5 and arranged vertically so that the installation height of the proximity switch 5 can be adjusted, and the slider is provided with a locking screw to limit the movement of the slider relative to the bracket bottom plate 6.

[0028] Optionally, the elastic support structure includes a plurality of support springs 2 distributed at intervals to achieve stable support for the load baffle 1.

[0029] Example

[0030] An elastic telescopic bracket for a proximity switch, such as Figures 1-2 As shown, it includes a bracket bottom plate 6, on which a support spring 2 and a proximity switch mounting frame 4 are installed; a load baffle 1 is installed on the support spring 2 to contact the load, and the proximity switch mounting frame 4 can be installed with a proximity switch 5; a signal baffle 3 is installed under the load baffle 1, and the signal baffle 3 can be horizontally moved and adjusted under the load baffle 1 to be within the signal sensing distance of the proximity switch 5; the interior of the proximity switch mounting frame 4 can be adjusted horizontally and vertically, so that the proximity switch 5 can be within the signal sensing distance of the signal baffle 3. The bracket bottom plate 6 can be installed on the equipment or other suitable positions by various installation forms such as welding or bolt connection. In order to better contact with the load to improve the contact stability, the load baffle 1 is V-shaped to increase the contact surface and rubber, engraving and other process technologies can be added to its contact surface to increase friction.

[0031] In order to better reflect its function, its working process is described below. Figure 2 In the embodiment, the load moves downward, approaches and contacts the load baffle 1, and moves downward with the signal baffle 3 to overcome the spring force of the supporting spring 2, so that the signal baffle 3 and the proximity switch 5 are within the sensing distance, and the proximity switch 5 sends out a working signal; when the load moves upward and leaves the load baffle 1, the load baffle 1 and the signal baffle 3 are pushed upward by the supporting spring 2, so that the signal baffle 3 and the proximity switch 5 are outside the sensing distance, and the proximity switch 5 stops sending a working signal.

[0032] The utility model effectively solves the problems in the prior art that the proximity switch has a short sensing distance adjustment, is limited in application scenarios, and is easily damaged by a load.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution, which should be included in the scope of the claims of the utility model.
