Description

Technical Field

[0001] This utility model relates to the field of building decoration technology, and in particular to a floor lifting device. Background Technology

[0002] During the decoration process, it is necessary to remove and peel off the original flexible building materials such as resilient flooring and carpet. Existing methods include using a knife to cut and peel off the adhesive layer between the resilient flooring / carpet and the ground, and then scraping off the flooring. For large areas of flooring, the scraping method is labor-intensive and requires squatting, which is time-consuming and laborious.

[0003] Alternatively, the floor or carpet can be lifted to one side and then pulled apart. This requires using a tool to clamp the floor or carpet, and then applying force to separate them. When operated by a single person, this is difficult because the clamping tool needs to be held manually, and considerable force is required when pulling. Furthermore, using a clamping locking mechanism involves frequent locking and unlocking, which is also time-consuming and laborious. Utility Model Content

[0004] The purpose of this utility model is to solve the above problems and provide a floor lifting device that clamps the floor and carpet materials when peeling them off and releases them when the tension is released. It is convenient for one person to operate with one hand.

[0005] The technical solution adopted by this utility model is:

[0006] A floor lifting device is characterized by comprising a lifting base and a clamp. The front end of the lifting base is provided with a retaining seat, the retaining seat includes a retaining groove and a rotating shaft disposed within the retaining groove. The clamp includes a first claw and a second claw. The tail end of the first claw is disposed within the retaining groove and rotates on the rotating shaft. The rear end of the second claw and the first claw are connected by a retaining pin and a retaining spring to form an elastic clamping structure. The tail end of the second claw extends rearward to the front end of the retaining seat. A handle is provided at the rear end of the lifting base.

[0007] Furthermore, the rear end of the pull seat forms left and right support pillars, and the handle is provided at the rear end of the support pillars, with a rubber pad on the handle.

[0008] Furthermore, a rotating wheel is provided on the rear side of the rotating shaft inside the slot. The rotating wheel protrudes from the card seat and engages with the tail end of the second claw.

[0009] Furthermore, the inner sides of the front ends of the first and second claws of the clamp are both provided with serrations, and the serrations of the two claws are corresponding and cooperate with each other.

[0010] Furthermore, reinforcing ribs are provided on the outer surface of the second claw of the clamp.

[0011] The beneficial effects of this utility model are:

[0012] (1) The clamp clamps the floor when the pull seat is pulled. The greater the pulling force, the greater the clamping force.

[0013] (2) When the pull seat is released, the clamping force is released due to the spring force of the clamp, and the clamping of the floor can be released;

[0014] (3) The structure is simple and can be operated by a single person to remove the floor. Attached Figure Description

[0028] The specific embodiments of the floor lifting device of this utility model will be described in detail below with reference to the accompanying drawings.

[0029] See appendix Figures 1 to 4The floor lifting device 1 includes a pull base 2 and a clamp 3. The front end of the pull base 2 is provided with a card seat 4. The card seat 4 includes a card groove 5 and a rotating shaft 6 provided in the card groove 5. The clamp 3 includes a first claw 7 and a second claw 8. The tail end of the first claw 7 is provided in the card groove 5 and rotates on the rotating shaft 6. The rear end of the second claw 8 and the first claw 7 are connected by a locking pin 9 and a retaining spring 10 to make the clamp 3 form an elastic clamping structure.

[0030] The elastic clamping structure includes protrusions 11 on the first claw 7 and the second claw 8, with a locking pin 9 passing through the protrusion 11. A retaining spring 10 is provided on the locking pin 9, which allows the first claw 7 and the second claw 8 to open in the normal state. Sawtooth teeth 12 are provided on the inner side of the front end of both the first claw 7 and the second claw 8, and the sawtooth teeth 12 of both claws correspond to each other and engage.

[0031] The outer surface of the second claw 8 is provided with reinforcing ribs 13, and the tail end extends backward to the front end of the card seat 4. The rear side of the rotating shaft 6 in the card slot 5 is provided with a rotating wheel 14. The rotating wheel 14 protrudes from the card seat 4 and cooperates with the tail end of the second claw 8. When the end face of the tail end of the second claw 8 slides, it forms a rolling cooperation with the rotating wheel 14.

[0032] A handle 15 is provided at the rear end of the pull seat 2, and the rear end of the pull seat 2 forms left and right support columns 16. A handle 15 is provided at the rear end of the support column 16, and a rubber pad is provided on the handle 15.

[0033] When using the floor lifting device 1 of this patent to peel off flooring or carpet, first lift one edge of the flooring or carpet, and clamp the open clamp 3 onto the edge of the flooring or carpet. Hold the handle 15 and lift the floor lifting device 1. Under the pull, the first claw 7 rotates around the pivot 6 and rotates towards the second claw 8. At the same time, the extended part of the tail end of the second claw 8 rotates and slides backward in cooperation with the rotating wheel 14, so that the second claw 8 also moves closer to the first claw 7. At this time, as the handle 15 is lifted, the clamp 3 formed by the first claw 7 and the second claw 8 clamps the edge of the flooring tighter and tighter. As the flooring is lifted, the adhesive layer between the flooring and the ground is peeled off, thus completing the peeling of the flooring or carpet and preparing for subsequent re-decoration.

[0034] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make several improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
