Description

Technical Field

[0001] The utility model relates to the technical field of stoppers, in particular to a connecting rod type stopper structure. Background Art

[0002] At present, when processing the counterweight on the forklift, a conveying mechanism is required for transportation, and a stopper is required for limiting the position at the processing node so that the counterweight can be processed or painted normally, and after the processing is completed, it needs to be dropped to transport the counterweight to the subsequent processing node.

[0003] However, the currently used stopper is a push-pull stopper. When the push-pull stopper is under a heavy load, the force of the cylinder cannot effectively pull the roller down to release the counterweight. Workers who scrape the plaster often need to use a crowbar to knock the stopper roller to release the counterweight. Over time, the roller is deformed during the knocking process, making it difficult to drop the stopper even after knocking, which greatly affects the normal progress of production work. Utility Model Content

[0004] The utility model aims to solve the problem in the prior art that the roller is deformed during the knocking process, which makes it difficult to drop the stopper after the knocking, greatly affecting the production work, and proposes the following technical solutions:

[0009] As an improvement of the above technical solution, the lower pull rod, the limiting rod and the driving pull rod are connected via a first rotating shaft.

[0010] As an improvement of the above technical solution, the limit rod is fixedly installed inside the fixing seat through a limit shaft passing through the inside for movement.

[0011] As an improvement of the above technical solution, the fixing seat includes a supporting seat, and a driving mechanism fixing seat is arranged on an upper end of one side of the supporting seat.

[0013] As an improvement of the above technical solution, one end of the fixing rod is movably connected to the upper end of the support seat through a fixing pin, and the lower end of the separate stop seat is connected to the upper end of the lower pull rod by a second rotating shaft.

[0014] As an improvement of the above technical solution, a limiting bolt is further installed on one side of the inner part of the support seat, and the position of the limiting bolt corresponds to that of the limiting rod.

[0015] Beneficial effects of the utility model:

DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution of the present utility model will be clearly and completely described below in conjunction with the embodiments.

[0022] Example

[0023] The connecting rod type stopper structure comprises:

[0024] A fixing seat 1, a stop rod 2 is installed at the upper end of the fixing seat 1, a connecting rod 3 is installed at the lower end of the stop rod 2, and a driving mechanism 5 is connected to one side of the connecting rod 3;

[0025] The fixing seat 1 comprises a supporting seat 11, and a driving mechanism fixing seat 12 is arranged at an upper end of one side of the supporting seat 11;

[0026] The support seat 11 can support and fix the whole body, making it more stable during linkage adjustment to avoid falling off. At the same time, the drive mechanism fixing seat 12 can install and fix the drive mechanism 5 to avoid falling off during the extension and retraction process.

[0027] The stop rod 2 includes a fixed rod 21, one end of which is connected to a separate stop seat 22, a roller is installed inside the upper end of the separate stop seat 22 through an axle, and a fixing pin 23 is installed at the other end of the fixed rod 21;

[0028] The fixed rod 21 is provided to limit the whole, and the separate stop seat 22 connected at one end can limit the conveyed counterweight, thereby improving the conveying efficiency after the counterweight is processed. In addition, by installing rollers inside the upper end, the counterweight can be moved more conveniently during the conveying process.

[0029] As an improvement of the above technical solution, one end of the fixing rod 21 is connected to the upper end of the support seat 11 through a fixing pin 23, and the lower end of the separate stop seat 22 is connected to the upper end of the lower pull rod 31 by a second rotating shaft 4, so that it can be positioned after installation to avoid falling off due to counterweight restrictions, while ensuring the stability of the counterweight during processing.

[0030] The linkage rod 3 includes a lower pull rod 31 and a limit rod 32 clamped to the lower end of the lower pull rod 31. A limit shaft 33 for limit movement is also installed at one end of the limit rod 32.

[0031] The lower pull rod 31 can be folded in cooperation with the limit rod 32 after being pulled by the driving mechanism, so as to drive the stop rod 2 connected to the upper end to move downward, so that the counterweight can be transported, which greatly improves the work efficiency.

[0032] As an improvement of the above technical solution, the limiting rod 32 is fixedly installed inside the fixing seat 1 through the limiting shaft 33 passing through the inside for movement, and can be positioned when pulling and adjusting to avoid falling off due to excessive pulling force.

[0033] The driving mechanism 5 comprises a driving cylinder 51, a telescopic rod 52 is clamped at the output end of the driving cylinder 51, and a driving pull rod 53 is connected to one end of the telescopic rod 52;

[0034] The driving cylinder 51 is connected to the external cylinder for telescopic work, so that the telescopic rod 52 installed with a piston inside can be adjusted after control, and the driving pull rod 53 is set, the connecting rod 3 can be pulled or pushed to move during the telescopic adjustment process, so that the stopper can be adjusted, thereby improving work efficiency.

[0035] As an improvement of the above technical solution, the lower pull rod 31, the limit rod 32 and the driving pull rod 53 are connected by the first rotating shaft 6, so that they can be fixed uniformly during the pushing and pulling process to avoid falling off between the three due to the pushing and pulling force.

[0036] In order to prevent the linkage rod 3 from flipping over during retraction, causing the stop rod 2 to tip to the other side and causing damage to the stopper, as well as obstruction to the conveying mechanism, a limit bolt 7 is also installed on one side of the support seat 11, and the limit bolt 7 corresponds to the position of the limit rod 32.

[0037] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
