[0021] 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.

[0022] See also Figure 1 The utility model provides a passenger and cargo elevator stop rod and elevator operation linkage device, comprising:

[0023] A stop rod 100, on which a first limiter 101 is provided;

[0024] The elevator door 200 is provided with a second stopper 201;

[0025] The first stopper 101 and the second stopper 201 are connected in series in the same electrical circuit. When both the first stopper 101 and the second stopper 201 are triggered to form a complete electrical circuit, the elevator can run.

[0026] This embodiment places two limiters in the same electrical circuit. When the stop rod of the passenger and cargo elevator is closed, the stop rod limiter will be triggered; at the same time, when the door of the passenger and cargo elevator is closed, the elevator door limiter will be triggered. Only when both limiters are triggered to form a complete electrical circuit can the elevator run. If the elevator door limiter is triggered but the stop rod limiter is not triggered, the electrical circuit is incomplete and the elevator cannot be started. The safety of the elevator operation is guaranteed and the safety of the construction work is improved.

[0027] In one embodiment, see Figure 1 One end of the stop rod 100 is rotatably connected to the support leg 300, and the other end is detachably connected to the support leg 300, and the bottom of the support leg 300 is connected to the elevator floor.

[0028] This embodiment is configured such that, by installing the stop rod 100 on the support leg 300 , a certain height is provided for the stop rod 100 , thereby providing a reliable protection effect for the operator.

[0029] It should be noted that the first limiter 101 is not necessarily installed on the stop rod 100 , but may also be installed on the support leg 300 , as shown in the accompanying drawings.

[0030] In one embodiment, see Figure 2 and Figure 3 A limiting groove 301 is provided on the top of the supporting leg 300 detachably connected to the stop rod 100 , and a buffer limiting structure is provided in the limiting groove 301 .

[0031] The present embodiment is configured in this way because the stop rod 100 is often opened and closed manually in actual use, and manual opening and closing is prone to cause impact damage when closing the stop rod 100. Therefore, a buffer limit structure is provided to reduce the impact force of the stop rod 100 when closing, thereby reducing damage to the stop rod 100 and the first limiter 101.

[0032] In one embodiment, see Figure 2 and Figure 3 The buffer limiting structure includes a buffer block 302 arranged in the limiting groove 301, an elastic member 303 is provided at the bottom of the buffer block 302, and a protrusion 304 is provided on the side wall of the buffer block 302, and the protrusion 304 is movably embedded in a sliding groove on the inner wall of the limiting groove 301.

[0033] This embodiment is configured such that when the stop rod 100 falls freely and closes, its end contacts the buffer block 302, and the buffer block 302 compresses the elastic member 303, thereby reducing the impact force of the stop rod 100 when it falls, and reducing damage to the stop rod 100 and the first limiter 101; during the movement of the buffer block 302, the protrusion 304 slides in the slide groove on the inner wall of the limiting groove 301, thereby ensuring the path guidance of the buffer block 302 and avoiding the buffer block 302 from moving at will, resulting in failure to achieve the buffering effect.

[0034] Specifically, the elastic member 303 may be a spring or an elastic gasket.

[0035] In one embodiment, see Figure 2 and Figure 3 A magnetic block 305 is provided on the surface of the buffer block 302 , and a rod sleeve 102 is sleeved on the end of the stop rod 100 .

[0036] This embodiment is configured such that if the impact force generated when the stop rod 100 falls is too large, resulting in intermittent bouncing and multiple collisions when in contact with the buffer block 302, the magnetic block 305 is provided so that when the stop rod 100 contacts the buffer block 302, the rod sleeve 102 at its end is adsorbed by the magnetic block 305 to ensure that the stop rod 100 does not separate from the buffer block 302, thereby better exerting the buffering effect of the buffer block 302.

[0037] Specifically, the rod sleeve 102 is made of magnetically absorbable material.

[0038] In one embodiment, see Figure 4 The stop bar 100 is provided with a reflective strip 103, which is arranged on the outer side of the stop bar 100. This embodiment is arranged in this way, and the setting of the reflective strip 103 can improve the warning effect at the stop bar 100, prompt the operator to pay attention, and improve safety.

[0039] 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.

[0040] 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.

[0041] 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.
