Embodiment 1

[0014] see Figure 1~Figure 3 , the compression elastic ball type door pin is composed of a fixed seat, a pin rod and an elastic ball, and is characterized in that: the fixed seat is an angle iron composed of a vertical base and a horizontal bolt seat; the pin rod It is a right-angled rod composed of a vertical long rod and a horizontal short rod fixedly connected to the upper end of the long rod; the bolt seat has a perforation and the long rod of the pin rod is dynamically mated, and the upper end of the bolt seat is fixedly connected to a guide The groove is slidingly matched with the long rod of the pin rod; the lower end of the long rod of the pin rod is fixedly connected with the elastic ball.

Embodiment 2

[0016] This embodiment is basically the same as Embodiment 1, and the special features are: the bottom of the guide groove is welded on the top of the base; the base is processed with mounting holes, and the inner side of the base has strong ribs; There are card slots at the upper end and 10mm±1mm from the lower end respectively, which can hold the short rod part of the pin rod.

[0017] The installation and working principle is as follows:

[0018] Fix the fixed seat 8 on the lower end of the door with screws at 80-120mm from the ground. When the door needs to be fixed, select the opening angle of the door, move the short rod part 11 of the pin rod 1, rotate the pin rod 1 to make it move down along the guide groove 2, and when the elastic ball 4 presses the ground, rotate the pin rod 1, make the short rod part 11 stuck in the slot 9, and then be fixed. The pressure of pin rod 1 makes elastic ball 4 shrink close to the ground, produces pressure and frictional force and can o...

Abstract

The invention relates to a compaction elastic-ball-type door bolt. The compaction elastic-ball-type door bolt consists of a fixed seat, an elastic ball and a pin rod, wherein the fixed seat is arranged at the bottom of a sliding door-window; the pin rod can move up and down along a guide groove of the fixed seat; the elastic ball is compacted or loosened, and the sliding door-window can be fixed at any position by using the friction force between the elastic ball and the ground, so that the compaction elastic-ball-type door bolt is good in flexibility, and damages caused by an ordinary door pin to the ground, the door-window or walls can be avoided.

Description

technical field [0001] The invention relates to a compression elastic ball type door pin. Background technique [0002] At present, the fixing method of the door of most families is to set the door stop on the wall, so that the door can only be fixed at its limit position when it is opened, which is poor in flexibility and very inconvenient. Using the elastic ball door pin to fix any open position of the door can better control the indoor air circulation, lighting, etc., and overcome the shortcomings of the door stopper and the damage to the door caused by the chair, stool and wooden wedge. Contents of the invention [0003] The object of the present invention is to overcome the disadvantages and deficiencies in the prior art, and provide an elastic ball door pin with simple structure, convenient installation, easy operation, practicality and reliability. [0004] The concrete idea that the present invention solves the above problems is as follows: [0005] A compression...
