Description

Technical Field

[0001] The utility model relates to the technical field of shelters, and more specifically to an adjustable proximity switch mounting frame and a shelter. Background Art

[0002] The switch cover signal proximity switch mounting bracket is a bracket used to install a proximity switch. A proximity switch is a sensor that is usually used to detect whether an object is close to or in contact with a surface and is commonly used in industrial automation control systems.

[0003] The existing switch cover signal proximity switch mounting frame adopts a structure that completely fixes the proximity switch. In actual use, when the top cover of the box-type equipment (cabin) is opened and closed (especially closed), the proximity switch using the fixed structure mounting frame is easily damaged due to the closing speed and weight of the top cover, thereby causing the proximity switch to lose its function.

[0004] In view of this, the prior art discloses an installation structure that can protect a proximity switch, which is designed as a compressible structure. Since the proximity switch is fixed on an upper support seat, it can be extended and retracted together with the upper support seat. However, in actual use, there is a situation where the top cover cannot completely compress the upper support seat, causing the upper support seat to tilt, thereby increasing the distance between the proximity switch and the sensor sheet, exceeding the sensing distance of the proximity switch, resulting in insufficient sensing.

[0032] The structure provided by the utility model is explained and illustrated in detail below in conjunction with the accompanying drawings of the specification.

[0033] refer to Figures 1 to 4 As shown, this embodiment specifically discloses an adjustable proximity switch mounting bracket, including: a lower support seat 1, which is used to fix the proximity switch 100, and the mounting bracket can be fixedly mounted on the cabin body through the lower support seat 1;

[0034] The connecting columns 3 are provided with two, and the bottoms of the connecting columns 3 are fixedly connected to the lower support base 1, and can be fixed by welding, and are evenly distributed on the left and right sides of the lower support base 1, that is, located on the left and right sides of the proximity switch 100; in some other embodiments, the number can also be adjusted according to the situation;

[0035] The spring 4 is sleeved on the connecting column 3. In the illustrated embodiment, each connecting column 3 is sleeved with a spring 4 to ensure support stability;

[0036] The upper support seat 5 is sleeved on the connecting column 33, and includes an upper bottom plate 51. The two ends of the upper bottom plate 51 are connected with upper vertical plates 52 extending vertically upward. The upper ends of the upper vertical plates 52 are connected with upper folding edges 53 extending horizontally inward. The upper bottom plate 51 is provided with a first through hole 511 and a second through hole 512. The upper part of the proximity switch 100 moves through the first through hole 511 and can slide up and down along the first through hole 511. The upper part of the connecting column 3 moves through the second through hole 512 and is fixed by the stopper 6. The spring 4 is sleeved on the connecting column 3 between the upper bottom plate 51 and the lower support seat 1.

[0037] When the upper folded edge 53 moves downward under force, that is, when the hatch cover of the cabin is in the process of closing, the lower end surface of the upper folded edge 53 can contact the upper end of the connecting column 3 to achieve limiting. At this time, the height of the upper end surface of the upper folded edge 53 is greater than the height of the upper end surface of the proximity switch 100 and is within the sensing range of the proximity switch 100.

[0038] Specifically, a sensing sheet is installed on the hatch cover. When the hatch cover is closed, the sensing sheet will move toward the upper support seat together with the hatch cover. When the sensing sheet contacts the upper folded edge 53 of the upper support seat 5 of the adjustable mounting frame, the sensing sheet enters the sensing distance range of the proximity switch 100. When the hatch cover contacts the upper support seat 5 due to speed and weight reasons and needs to be pressed down further, the folded edges on both sides of the upper support seat 5, i.e., the lower edges of the upper folded edges 53, will contact the connecting column 3, thereby limiting the position (in this embodiment, the distance between the lower edge of the upper folded edge 53 and the connecting column 3 is 3 mm, and the distance between the upper edge of the upper folded edge 53 and the highest point of the proximity switch 100 is 4 mm. After the hatch cover compresses the upper support seat to the limit position, the highest point of the proximity switch 100 will maintain a gap of 1 mm with the hatch cover. In some other embodiments, the distance between the upper edge of the upper folded edge 53 and the highest point of the proximity switch 100, and the distance between the upper edge of the upper folded edge 53 and the highest point of the proximity switch 100 are 2 mm. The distance from the highest point of the switch 100 can also be set to other values, as long as it is ensured that when the lower edge of the upper folded edge 53 contacts the connecting column 3, the upper edge of the upper folded edge 53 is higher than the highest point of the proximity switch 100, that is, a gap is formed, and at the same time, the gap is within the sensing range of the proximity switch 100), thereby ensuring that the upper support seat 5 no longer moves downward. At this time, the upper edge of the upper folded edge 53 is higher than the highest point of the proximity switch 100, avoiding the sensor sheet from directly pressing on the proximity switch 100, and being within the sensing range of the proximity switch 100, thereby protecting the proximity switch 100 and realizing the function of sensing limit.

[0039] It should be noted that, in the present embodiment, since the proximity switch 100 is fixed on the lower support seat 1, when the hatch cover is pressed downward and drives the upper support seat 5 to be pressed downward, the proximity switch 100 will not move downward with the upper support seat 5, but will gradually move closer to the hatch cover, and the distance between the proximity switch 100 and the sensing sheet on the hatch cover will gradually decrease until the upper folding edge 53 is limited and fixed by the connecting column 3. At this time, the distance between the proximity switch 100 and the sensing sheet is the smallest, which can avoid the situation where the proximity switch cannot sense in place. At the same time, since there is a gap between the proximity switch 100 and the upper folding edge 53 of the upper support seat 5, there is also a gap between the proximity switch 100 and the hatch cover, thereby avoiding pressure damage to the contact switch 100.

[0040] In some embodiments, the overall cross-section of the lower support seat 1 is roughly Ω-shaped, including a lower base plate 11, and the two ends of the lower base plate 11 are connected to lower vertical plates 12 extending downward, and the lower vertical plates 12 are connected to a lower folding edge 13 extending outward, and a mounting hole 131 is provided on the lower folding edge 13. The mounting hole 131 can be used to fix the entire mounting frame on the cabin body of the cabin, and the proximity switch 100 is fixed to the middle part of the lower base plate 11; in a preferred embodiment, the proximity switch 100 can be detachably mounted on the lower base plate 11 by a first fixing nut 7 and a second fixing nut 8, the first fixing nut 7 is located at the upper end of the lower base plate 11, and the second fixing nut 8 is arranged at the lower end of the lower base plate 11. It can be understood that a through hole for the proximity switch 100 to pass through is provided on the lower base plate 11, and a thread is provided on the peripheral side of the proximity switch 100. In combination with the first fixing nut 7 and the second fixing nut 8, the proximity switch 100 can be detachably fixed to the lower base plate 11, i.e., the lower support seat 1, thereby facilitating maintenance and replacement.

[0041] Among them, the lower bottom plate 11 is supported by the lower vertical plate 12, and an inverted U-shaped notch is formed between the two lower vertical plates 12 and the lower bottom plate 11, so that a certain space is formed between the lower bottom plate 11 and the cabin. In this embodiment, by increasing the height of the lower vertical plate 12, the depth of the notch of the lower support seat can be increased, which can ensure that the lower part of the proximity switch 100 can be easily disassembled after the cable connector is installed, avoiding the phenomenon of the cable connector being soaked in water in a rainy environment. Specifically, in a preferred embodiment, the distance H between the bottom of the proximity switch 100 and the lower folding edge 13 is set to 20mm-40mm, preferably 30mm-35mm.

[0042] In this embodiment, the limiting member 6 includes a spring pressing piece 61 and a cotter pin (not shown in the figure). A penetrating positioning hole 31 is opened in the radial direction of the upper end of the connecting column 3. The cotter pin is inserted into the positioning hole 31. The spring pressing piece 61 is sleeved on the connecting column 3 and is located between the cotter pin and the upper base plate 51. The upper support seat is limited by the cotter pin and the positioning hole 31, which can facilitate disassembly and maintenance. The setting of the spring pressing piece 61 can increase the force-bearing area of ​​the contact between the cotter pin and the upper base plate 51.

[0043] Continue to combine Figure 3 and Figure 4As shown, the lower base plate 11, the lower vertical plate 12 and the lower folding edge 13 are an integrally formed structure; the upper base plate 51, the upper vertical plate 52 and the upper folding edge 53 are also an integrally formed structure; that is, the lower support seat 1 and the upper support seat 5 are both integrally formed structures, and the bending parts of the lower support seat 1 and the upper support seat 5 are both provided with fillets 2, that is, the connection between the lower base plate 11 and the lower vertical plate 12, the connection between the lower vertical plate 12 and the lower folding edge 13, the connection between the upper base plate 51 and the upper vertical plate 52, and the connection between the upper vertical plate 52 and the upper folding edge 53 are all provided with fillets 2. The integrally formed structure can improve the overall structural strength of the upper support seat 5 and the lower support seat 1, and is easy to process and manufacture. Fillets are provided at each bending part, that is, arc transition, which can disperse stress concentration, thereby improving the strength and service life of the upper support seat 5 and the lower support seat 1.

Specifically, the shelter comprises a cabin body and a hatch cover, an opening is formed on the cabin body, the hatch cover is flipably arranged on the cabin body for controlling the opening and closing of the opening, and an opening and closing mechanism may be arranged on the cabin body for controlling the opening and closing of the hatch cover. Optionally, the opening and closing mechanism comprises a retractable mechanism such as an electric cylinder, a hydraulic cylinder, or a pneumatic cylinder, and the automatic opening and closing of the hatch cover is controlled by retracting;

[0045] The adjustable proximity switch mounting frame is mounted on the cabin body, the proximity switch 100 is mounted on the mounting frame, and a corresponding induction sheet is arranged on the hatch cover. The proximity switch 100 is used to detect the position of the induction sheet. When the hatch cover is closed at the opening, the hatch cover is pressed against the upper folding edge and the spring 4 is in a compressed state. It can be understood that after the hatch cover is closed, the induction sheet is just located directly above the proximity switch 100. Of course, the number of mounting frames and proximity switches 100 can be set according to the size of the cabin body, which is not limited here. When the hatch cover is opened, the compressed spring 4 will push the upper support seat to move upward until it is limited by the cotter pin.
