[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. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-3 The utility model provides an installation protection device for a pull-wire switch, which relates to a pull-wire switch 100, which has two installation feet 101, and the ends of the installation feet 101 are provided with limit blocks 102, and the bottom surface of the limit blocks 102 is an arc surface; it also includes,

[0021] The base 200 is provided with a groove 201 adapted to the mounting foot 101 , and a mounting structure is provided in the groove 201 , which moves in contact with the bottom surface of the limit block 102 inserted into the groove 201 and moves to the top surface of the limit block 102 to limit it.

[0022] In this embodiment, the installation foot 101 of the pull-cord switch 100 is aligned with the groove 201 on the base 200 and inserted from top to bottom, and the limit block 102 is against the installation structure. As the installation process continues, the installation structure slides along the bottom surface of the limit block 102 to the top surface to limit the installation foot 101. The operation is simple and quick, which reduces the difficulty of installation and improves the installation efficiency.

[0023] In one embodiment, see Figure 3 The mounting structure includes a spherical block 202, which is rotatably arranged at one end of a support rod 203, and the other end of the support rod 203 is connected to an elastic member 204. Specifically, the elastic member 204 can be an elastic telescopic rod.

[0024] This embodiment is configured such that when the mounting foot 101 is inserted into the groove 201, the limit block 102 abuts against the spherical block 202, and as the limit block 102 gradually extends, the spherical block 202 slides along the bottom surface of the limit block 102, and when the mounting foot 101 is completely in place, the spherical block 202 slides to the top surface of the limit block 102, and the mounting foot 101 is fixed in the groove 201. The sizes of the support rod 203 and the limit block 102 can be adjusted according to needs, and it is sufficient to ensure that after the support rod 203 is pressed on the limit block 102, the overall stability of the pull-cord switch 100 is guaranteed.

[0025] In one embodiment, see Figure 3 The limiting block 102 has a limiting groove 103 on its top surface. After the spherical block 202 moves along the bottom surface of the limiting block 102 to its top surface, the bottom surface of the support rod 203 is adapted to be connected with the limiting groove 103 .

[0026] This embodiment is configured such that after the mounting foot 101 is installed in place, the support rod 203 is adapted to be connected with the limiting groove 103 on the top surface of the limiting block 102, which can increase the stability of the support rod 203, reduce the risk of the support rod 203 moving horizontally, and thus improve the overall stability.

[0027] In one embodiment, see Figure 2 and Figure 3 A support plate 205 is disposed in the groove 201, a bottom elastic member 206 is disposed at the bottom of the support plate 205, and the top of the support plate 205 is embedded in the bottom surface of the mounting foot 101. Specifically, the bottom elastic member 206 can be a spring.

[0028] This configuration of the present embodiment can provide more space for the installation of the mounting foot 101, so that the spherical block 202 can be smoothly moved to the top surface of the limiting block 102. At the same time, the support plate 205 and the support rod 203 limit the mounting foot 101 in both directions, which provides better stability.

[0029] In one embodiment, see Figure 1A pull rope 207 is inserted into the base 200 , one end of the pull rope 207 is connected to the support rod 203 , and the other end extends to the outside of the base 200 and is bolted to the pull ring 208 .

[0030] The present embodiment is configured such that when the staff disassembles the pull-cord switch 100, they pull the pull ring 208 to pull the pull cord 207 outward, driving the support rod 203 to compress the elastic member 204, so that the spherical block 202 retracts and disengages from the limit block 102, so that the mounting foot 101 is released from the limit, and the pull-cord switch 100 is disassembled, which is simple and quick to operate.

[0031] In one embodiment, see Figure 1 A pull rope 207 is shared between the support rods 203 corresponding to the positions of the two mounting feet 101, and a pull ring 208 is located at the front side of the base 200. A guide wheel 209 is provided on the side wall of the base 200 for steering the pull rope 207.

[0032] The present embodiment is configured in such a way that when disassembling the pull-cord switch 100, the staff only needs to pull a pull cord 207 to quickly release the limit of the installation feet 101 on both sides, thereby efficiently achieving disassembly, being simple and quick to operate, and improving work efficiency.

[0033] In one embodiment, see Figure 1 , and also includes an insertion rod 300, which is inserted into the base 200 and extends into the groove 201, and a socket adapted to the insertion rod 300 is opened on the installation foot 101.

[0034] This embodiment is configured such that whether to use the insertion rod 300 is selected according to the installation environment. If the vibration in the use environment is strong, the insertion rod 300 can be inserted to further lock the position of the installation foot 101, thereby avoiding the problem of the installation foot 101 shaking up and down slightly due to the installation of the support plate 205, thereby improving the overall stability.

[0035] It should be noted that if the embodiments of the present invention involve directional indications such as up, down, left, right, front, back, etc., then the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture as shown in the accompanying drawings. If the specific posture changes, the directional indication will also change accordingly.

[0036] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the utility model, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the meaning of "and / or" appearing in the full text includes three parallel schemes. Taking "A and / or B" as an example, it includes scheme A, or scheme B, or schemes that satisfy both A and B. In addition, "multiple" refers to more than two. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist.

[0037] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
