Description

Technical Field

[0001] The utility model relates to the technical field of switches, in particular to an adjustable anti-dumping switch. Background Art

[0002] The anti-dump switch is used to detect the tilt state of an object and send a signal after the object dumps to prevent accidents caused by the object dumping.

[0003] Although the existing anti-dump switch can monitor the tilt angle of an object and send a signal during use, in actual use, since the existing anti-dump switch does not have an adjustment mechanism, it is not convenient for the user to adjust the position and size of the installation base according to actual conditions during installation, thereby reducing the practicality and scope of use of the existing anti-dump switch. For this reason, we propose an adjustable anti-dump switch. Utility Model Content

[0004] In view of the deficiencies of the prior art, the utility model provides an adjustable anti-dumping switch, which has the advantages of strong practicability and good stability, and solves the problems raised by the above-mentioned background technology.

[0005] The utility model provides the following technical solution: an adjustable anti-dump switch, comprising a main body, a limit shell fixedly assembled at the bottom of the main body, installation grooves are provided on both side inner walls of the limit shell, a movable groove is provided on the bottom inner wall of the limit shell, a straight rod is fixedly assembled on the inner wall of the installation groove, a reset spring is sleeved on the outer edge of the straight rod, the top end of the reset spring overlaps the limit base, a positioning plate one is fixedly assembled on the bottom of the limit base, and a positioning plate two is also fixedly assembled on the outer wall of the main body.

[0006] As a preferred technical solution of the utility model, the outer walls of the positioning plate 2 and the positioning plate 1 are both provided with positioning holes, and the main body is fixed by the cooperation of the existing bolts and the positioning holes.

[0007] As a preferred technical solution of the utility model, the number of the return springs is two, and the two return springs are symmetrically distributed along the inner wall of the installation groove.

[0008] As a preferred technical solution of the utility model, the inner wall of the installation groove and the inner wall of the movable groove are slidably connected to the limiting base and the outer wall of the positioning plate 1 respectively.

[0009] As a preferred technical solution of the utility model, the straight rod and the limiting base are both made of galvanized iron metal.

[0010] As a preferred technical solution of the utility model, the shape of the positioning plate one is set to be "L" type. After the bolt on the positioning plate one is threadedly connected with the positioning hole on the positioning plate one, its top end overlaps with the bottom of the positioning plate two, and the bottom of the bolt on the positioning plate two overlaps with the outer wall of the positioning plate one.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] 1. The adjustable anti-dump switch, through the provided main body, limit shell, positioning plate 2, limit base, and mounting groove structure, enables the installer to pull the positioning plate 1 to make the limit base slide along the inner wall of the mounting groove to compress the reset spring during the use of the anti-dump switch, thereby making the length between the limit shell and the positioning plate 1 adjustable, and at the same time increasing the distance between the positioning plate 1 and the positioning plate 2, so that the user can install and fix the main body according to actual conditions, thereby improving the practicality and use range of the anti-dump switch.

[0013] 2. The adjustable anti-dump switch is provided with a movable groove, a limit base, and an installation groove structure. When the user pulls the positioning plate 1, the limit base can limit the positioning plate 1, thereby ensuring that the positioning plate 1 cannot separate from the limit shell and the inner wall of the movable groove, thereby improving the tightness of the connection structure between the limit shell and the positioning plate 1. At the same time, with the thrust of the reset spring on the limit base, the anti-dump switch can automatically reset the positioning plate 1 to the initial state after disassembly, which will not affect the subsequent use of the anti-dump switch. It has the characteristics of simple structure and good stability, and has certain promotion value. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] 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. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

[0020] See also Figure 1-4 , an adjustable anti-dump switch, including a body 1, a limit shell 2 is fixedly assembled at the bottom of the body 1, and both side inner walls of the limit shell 2 are provided with mounting grooves 7, and the bottom inner wall of the limit shell 2 is provided with a movable groove 5, and the inner wall of the mounting groove 7 is fixedly assembled with a straight rod 8, and the outer edge of the straight rod 8 is sleeved with a reset spring 9, and the top of the reset spring 9 overlaps the limit base 6, and the bottom of the limit base 6 is fixedly assembled with a positioning plate 1 3, and the outer wall of the body 1 is also fixedly assembled with a positioning plate 2 4. Through the provided positioning plate 1 3 and positioning plate 2 4 structure, the anti-dump switch only needs to be threadedly connected with the threaded holes on the positioning plate 1 3 and the positioning plate 2 4 by two bolts, which is convenient for users to install the anti-dump switch and improves the user's work efficiency.

[0021] In a preferred embodiment, positioning holes are provided on the outer walls of positioning plate 2 4 and positioning plate 1 3, and the main body 1 is fixed by the cooperation of bolts and positioning holes in the prior art. The positioning holes can be fixed by being threadedly connected with the bolts, thereby ensuring the stability of the main body 1 after installation, and also facilitating the user to perform installation operations thereon.

[0022] In a preferred embodiment, there are two return springs 9, and the two return springs 9 are symmetrically distributed along the inner wall of the mounting groove 7. The two return springs 9 can apply a thrust to the limit base 6, allowing the limit base 6 to be smoothly reset after the anti-dump switch is removed. The thrust can be applied to the limit base 6 to achieve the effect of automatic reset, and at the same time, the limit base 6 can be smoothly moved by cooperating with the straight rod 8 to limit the limit base 6, thereby improving the stability of the limit base 6 during the sliding process.

[0023] In a preferred embodiment, the inner wall of the mounting groove 7 and the inner wall of the movable groove 5 are respectively slidably connected to the limit base 6 and the outer wall of the positioning plate 3. The mounting groove 7 can facilitate the user to install the straight rod 8 and the return spring 9 to ensure that there is enough space to accommodate the straight rod 8 and the return spring 9, so that the anti-dump switch has the advantages of small size and high portability.

[0024] In a preferred embodiment, the straight rod 8 and the limit base 6 are both made of galvanized iron metal. The galvanized iron metal has the characteristics of hardness and low cost, which can effectively reduce the wear of both and also reduce the production cost of the anti-dump switch.

[0025] In a preferred embodiment, the shape of the positioning plate 3 is set to be "L" type. After the bolt on the positioning plate 3 is threadedly connected with the positioning hole on the positioning plate 3, its top end overlaps with the bottom of the positioning plate 2 4, and the bottom of the bolt on the positioning plate 2 4 overlaps with the outer wall of the positioning plate 3. The shape of the positioning plate 3 can ensure that the bolt contacts the positioning plate 2 4 after installation to generate resistance to fix the main body 1, thereby achieving the effect of quickly fixing the main body 1. At the same time, after the distance between the limit shell 2 and the positioning plate 3 is adjusted, only the length of the bolt needs to be adjusted to achieve the fixation of the main body 1, thereby improving the use range of the anti-dump switch.

[0026] Working principle: first, after the user installs the anti-dump switch, adjust the distance between the limit shell 2 and the positioning plate 3 according to the actual size of the base in the installation area. The specific operation steps are: pull the positioning plate 3 to make the limit base 6 compress the reset spring 9. At this time, the limit base 6 will slide along the inner wall of the installation groove 7, and the distance between the limit shell 2 and the positioning plate 3 will increase. Place the base between the limit shell 2 and the positioning plate 3, and then use bolts to threadedly connect with the positioning holes on the positioning plate 3 and the positioning plate 4 respectively, so that the main body 1 is fixed. When disassembling, remove the bolts through the above-mentioned reverse steps. After picking up the main body 1, the limit base 6 is pushed by the two reset springs 9 and automatically resets.

[0027] Although 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.
