Abstract

The utility model relates to an arresting pin. The utility model is characterized in that a guide sleeve is fixed to an arresting hole of a plate, a bolt in the guide sleeve can longitudinally shift, the diameter of a pin rod of the bolt is smaller than the diameter of a pin head, a hole at the rear end of the guide sleeve can only pass through the pin rod, a fixed handle on the tail end of the pin rod can be clamped in a cross slot at the rear end of the guide sleeve to limit a torsion and a compression spring arranged in the guide sleeve can make the bolt bear the constant force in the locking direction. The arresting pin has the advantages of convenient operation and reliable locking.

Description

A kind of stop pin

The utility model relates to a kind of latch, the interlace stop pin of displacement of two plate objects that particularly a kind of restriction is taken mutually.

There are multiple two to take the interlace situation of displacement of plate object mutually.As, the folding of two fan sliding windows, the two sash displacement of taking mutually and interlace exactly.If run through two window sash frame lap-joints, then can limit the two dislocation and move with a pin.And for example, the folding joint of folding bicycle, two joint connecting plates are to fashionable, and two connecting plates respectively protrude an engaging lug to be taken mutually, inserts a pin and runs through two engaging lugs, limit both and misplace and move this folding joint that has been fastening.General stop pin is a shaft, and it inserts in stop hole, can be because of vibrations etc. former thereby twist in addition from the hole vibrations break away from, thereby the reliability of conventional stop pin dislikes poor.

The purpose of the utility model be provide a kind of easy to operate and lock reliable stop pin.

Stop pin described in the utility model, guide pin bushing at the stop hole place of plate fixed vertical plate face, there is latch to vertically move in the guide pin bushing along it, the pin of a latch diameter is identical with the nominal size of stop hole, the diameter of pin rod is less than the pin head, pin rod only can be passed through in the hole of rear end of conducting sleeve, and rear end of conducting sleeve has translot, the fixing handle that can snap in translot of pin rod tail end.

Constant stressed for guaranteeing latch to being seated direction, on the pin rod of latch, be with stage clip, the two ends of stage clip push against the aft bulkhead of pin head and guide pin bushing respectively.

Stop pin described in the utility model, its latch and a plate structurally become one, and can guarantee that the axis advance and retreat that latch is parallel to stop hole move, and only depend on and draw or press latch to get final product execution, and be easy to operate.The handle of pin rod tail end snaps in and can prevent the latch twisting in the rear end translot of guide pin bushing, and the reliability that locks is improved.Be with reliable that stage clip more can guarantee to lock on the pin rod.

The sectional view of Fig. 1 stop pin locking state;

The sectional view of Fig. 2 stop pin open mode;

The sectional view of Fig. 3 stop pin.

Have on plate 1, two plates of take mutually two displacements that can interlace can be overlapping stop hole, fixing guide pin bushing 2 on plate wherein, latch 3 can vertically move in guide pin bushing 2.The pin of a latch 3a is identical with the stop hole nominal size, and the diameter of pin rod 3b is less than pin head 3a, and the porose pin rod 3b that makes in guide pin bushing 2 rear ends can pass.Guide pin bushing 2 rear ends have translot 5, and the fixing handle 4 of pin rod 3b tail end can snap in the translot 5, and handle 4 is straight-bars, as Fig. 1.Pull out latch 3 and rotate 90 °, handle 4 is horizontally placed on the groove 5, can guarantee that latch maintains open mode.Be with stage clip 6 on the pin rod 3b, its two ends push against the aft bulkhead of pin head 3a and guide pin bushing 2 respectively.Handle 4 is annulus.

Claims

1, a kind of stop pin, it is characterized in that: the stop hole place fixed vertical of a plate (1) is in the guide pin bushing (2) of plate face, there is latch (3) to vertically move in the guide pin bushing (2) along it, pin head (3a) diameter of latch is identical with the nominal size of stop hole, the diameter of pin rod (3b) is less than pin head (3a), pin rod (3b) only can be passed through in the hole of guide pin bushing (2) rear end, and rear end of conducting sleeve has translot (5), the fixing handle (4) that can snap in translot (5) of pin rod (3b) tail end.

2, by the described stop pin of claim 1, it is characterized in that the two ends that are with stage clip (6), stage clip on the pin rod (3b) push against the rear wall of pin head (3a) and guide pin bushing (2) respectively.
